TECHNICAL FIELD

The present disclosure relates to a technical field of crimping equipment, and in particular to crimping pliers.

BACKGROUND

There are so many tools used in traditional industrial wiring, such as screwdrivers, needle-nose pliers, wire strippers or pipe cutters, etc. Each tool has its own specific use method and purpose. The most important part is the wiring part used to connect electrical appliances. The fastest way for early construction masters to connect the wires was to peel off a small section of the outer sheath of the wires to expose the internal metal wires, and then wrap them directly around the contacts of electrical appliances. This connection method is not allowed under current industrial wiring regulations. The reason is that the connection through metal wires is not stable enough at all and is easily broken and deformed. As a result, the circuit is disconnected and leads to a major disaster. In order to solve this problem, crimping pliers are currently used to achieve a more stable connection between wires.

There are many types of crimping pliers in the prior art, and various special wiring and crimping tools need to be prepared according to the type and model of wiring. For construction sites that require a variety of wiring requirements, a variety of crimping pliers are needed at the same time. Traditional crimping pliers can only meet the wiring requirements of one or two sizes of cables of a single line type. Corresponding wiring and crimping tools are still needed for different types of line types. The disadvantage is that the number of tools is large, and the tool bag is large and heavy. It is inconvenient to carry and the cost of purchasing tools is high.

The following describes in detail the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are not intended to limit the present disclosure.

In order to make the purpose, technical solutions, and advantages of the present disclosure clear, the following further describes the present disclosure in detail with reference to accompanying drawings and embodiments.

FIG.1toFIG.3show a schematic structural diagram of an embodiment of the crimping pliers. Referring toFIG.1toFIG.3, the present disclosure provides a crimping pliers, comprising: a first plier member1, a second plier member2, a limiting component3, a first crimping module4, a second crimping module5. The first plier member1comprises a first clamping part11and a first handle12connected with the first clamping part11; the first clamping part11comprises two first clamping pieces111spaced apart to form a first clamping gap112; a first magnetic component13is disposed in the first clamping gap112at the jaw of the first clamping part11; the second plier member2comprises a second clamping part21, a connecting member22and a second handle23; one side of the connecting member22is fixedly arranged on the second clamping part21; one end of the connecting member22is pivotally connected in the first clamping gap112on one side of the first clamping part11, and the other end is pivotally connected to one end of the second handle23; the second clamping part21comprises two second clamping pieces211spaced apart to form a second clamping gap212; a second magnetic component24is disposed in the second clamping gap212at the jaw of the second clamping part21. The limiting component3is provided between the first handle12and the second handle23to provide support when a gripping force is applied to the first handle12and the second handle23. The first crimping module4is detachably disposed in the first clamping gap112at the jaw of the first clamping part11and is adsorbed by the first magnetic member13. The second crimping module5is detachably disposed in the second clamping gap212at the jaw of the second clamping part21and is adsorbed by the second magnetic member24. It should be noted that the first crimping module4and the second crimping module5are made of materials that can be attracted by the magnetic force generated by the first magnetic component13and the second magnetic component24.

Preferably, in this embodiment, the first clamping part11and the first handle12are integrally formed, thereby increasing the strength of the first plier member1and extending the service life of the crimping pliers.

Preferably, the connecting member22is configured in a triangular shape, with one corner fixed to the second clamping part21through two through-axes. And insert the other corner into the first clamping gap112on one side of the first clamping part11and pivot it, and pivot the last corner with one end of the second handle23.

Specifically, when using the crimping pliers, hold the first handle12and the second handle23tightly, under the support of the limiting component3, the rear end of the second handle23moves in a direction closer to the first handle12, and the front end of the second handle23moves in a direction away from the first handle12, driving the end of the connecting member22connected to the second handle23to move. The other end of the connecting member22is pivotally connected to the first clamping part11, so that the side of the connecting member22fixedly connected to the second clamping part21moves, driving the second clamping part21to move toward the first clamping part11, thereby compressing the wires between the first crimping module4and the second crimping module5.

Preferably, in this embodiment, the first handle12and the second handle23are both covered with rubber sleeves6, and the rubber sleeves6are provided with anti-slip patterns.

In this embodiment, the crimping module is detachably disposed at the jaws of the first clamping part11and the second clamping part21of the crimping tool, so that the crimping module can be disassembled and replaced. In this way, crimping modules of different line types can be matched according to needs.

Furthermore, referring toFIG.4, the second handle23comprises a first handle piece231and a second handle piece232spaced apart from each other; one end of the first handle piece231is provided with a first engaging hole233; the same end of the second handle piece232is provided with a second engaging hole234facing the first engaging hole233; one end of the connecting member22is inserted into the gap between the first handle piece231and the second handle piece232and is provided with a through hole221directly opposite the first engaging hole233; an adjustment pin25is provided in the first engaging hole233, the second engaging hole234and the through hole221.

Furthermore, referring toFIG.5, the adjustment pin25comprises a knob portion251arranged in sequence, a first engaging portion252matching the first engaging hole233, an eccentric shaft253matching the through hole221, a second engaging portion254matching the second engaging hole234, a threaded portion255, and a nut256screwed to the threaded portion255.

It should be noted that when the adjustment pin25is installed into the first engaging hole233, the through hole221and the second engaging hole234, the first engaging portion252engages with the first engaging hole233. The first engaging portion252is configured in an angular shape, such as a triangle, a quadrilateral, a polygon, etc. The first engaging hole233is configured in a shape matching the first engaging portion252. Therefore, when the first engaging portion252is engaged with the first engaging hole233, the mutual cooperation between the first engaging portion252and the first engaging hole233can make the adjustment pin25and the second handle23relatively fixed. The through hole221is engaged with the eccentric shaft253. It should be noted that the center line of the eccentric shaft253does not coincide with the center line of the entire adjustment pin25. That is, when the adjustment pin25rotates to drive the eccentric shaft253to rotate, the eccentric shaft253can drive the connecting member22to move. The movement of the connecting member22can drive the first crimping module4and the second crimping module5to move closer to or away from each other. When equal force is applied to the first handle12and the second handle23, if the first crimping module4and the second crimping module5are closer, the clamping force generated between the first crimping module4and the second crimping module5will be greater. If the first crimping module4and the second crimping module5are further apart, the clamping force generated between the first crimping module4and the second crimping module5will be smaller.

Specifically, by providing the adjustment pin25, when it is necessary to adjust the clamping strength between the first crimping module4and the second crimping module5, the user can manually squeeze the nut256to cause the adjustment pin25to move upward for a certain distance, so that the first engaging portion252and the first engaging hole233are disengaged, and then the knob portion251is rotated to drive the eccentric shaft253to rotate, thereby driving the connecting member22to rotate. To adjust the distance between the first crimping module4and the second crimping module5, after the adjustment, squeeze the knob part251again to make the first engaging portion252snap into the first engaging hole233, and the adjustment is completed.

Preferably, the first engaging portion252and the first engaging hole233are set in a regular polygon, such as a regular hexagon. When adjusting, each side can correspond to an adjustment gear. For example, the regular hexagonal first engaging portion252can set the adjustment gears to six gears, and each time the adjustment pin25is rotated 60 degrees, it is one gear.

Furthermore, the second engaging portion254is covered with a first elastic member257, and the first elastic member257is located between the nut256and the second handle piece232.

Specifically, by arranging the first elastic member257, when the nut256is squeezed to cause the first engaging portion252to disengage from the first engaging hole233, the first elastic member257undergoes elastic deformation and exerts a reverse thrust on the nut256. When the adjustment pin25is rotated to a certain angle so that the first engaging portion252can engage in the first engaging hole233, under the elastic force of the first elastic member257, the first engaging portion252automatically snaps into the first engaging hole233. There is no need to manually engage the first engaging portion252into the first engaging hole233, making the adjustment process more convenient and faster.

Furthermore, in this embodiment, referring toFIG.3, a second elastic member7is provided between the connecting member22near the second handle23and the first clamping part11.

Specifically, the second elastic member7is in a normal state when the first handle12and the second handle23are not gripped tightly. When the first handle12and the second handle23are held tightly, the pivot point of the connecting member22and the second handle23moves in a direction away from the first handle12. The first crimping module4and the second crimping module5are clamped, the second elastic member7is in a stretched state, and the second elastic member7generates a pulling force between the connecting member22near the second handle23and the first clamping part11. When the first handle12and the second handle23are released, under the pulling force of the second elastic member7, the pivot joint between the connecting member22and the second handle23moves toward the first handle12, the first crimping module4and the second crimping module5are opened. By providing the second elastic member7, when the first handle12and the second handle23are released, the crimping pliers can automatically return to the open state, making it convenient for the user to perform the next crimping operation.

Furthermore, referring toFIG.6, the limiting component3comprises a limiting rod31and a limiting part32, both ends of the limiting rod31are pivotally connected to the first handle12and the second handle23respectively; one end of the limiting rod31pivotally connected to the second handle23is provided with a tooth groove311; the limiting part32includes an internal hollow shaft body321and a third elastic member322. The shaft body321is pivotally assembled on the second handle23and close to the tooth groove311; the outer wall of the shaft body321is provided with a cog part323, a dialing part324and a hooking part325that match the tooth groove311; one end of the third elastic member322is connected to the second handle23, and the other end of the third elastic member322is connected to the hooking part325.

Specifically, both ends of the limiting rod31are pivotally connected to the first handle12and the second handle23respectively, so that when the first handle12and the second handle23are grasped, the limiting rod31rotates, thereby driving the tooth groove311to rotate. After the tooth groove311rotates to a certain angle, it meshes with the cog part323. At this time, even if the first handle12and the second handle23are released, the first handle12and the second handle23will maintain the gripped state due to the cooperation of the tooth groove311and the cog part323. When it is necessary to release the grip state, move the dialing part324to disengage the cog part323from the tooth groove311. After losing the support of the cog part323, the first handle12and the second handle23move away from each other under the action of the second elastic member7. The first crimping module4and the second crimping module5are switched to the open state.

Furthermore, in this embodiment, referring toFIG.7, a first guide body113is provided at the jaw of the first clamping part11, and a second guide body213is provided at the jaw of the second clamping part21; the first guide body113and the second guide body213are both provided with limiting slide rails8, and the first magnetic member13and the second magnetic member24are provided at the ends of the slide rails8; the first crimping module4and the second crimping module5are both provided with slide grooves9that match the limiting slide rails8.

Specifically, by arranging the slide rails8at the pliers mouth, arranging the magnetic members at the end of the slide rails8, and arranging the slide grooves9on the crimping module, on the one hand, it enables the crimping module to quickly align itself with the magnetic members during installation and be absorbed by the magnetic members. On the other hand, the crimping module can only move along the direction of the slide rail8, and with the magnetic component provided at the end of the slide rail8, the function of fixing the crimping module is further improved.

Furthermore, in order to improve the practicality of the crimping pliers, in some embodiments, referring toFIG.3andFIG.8, the connection between the first handle12and the first clamping part11is provided with a installation housing14and a fixed installation groove15, one of the two first clamping piece111is provided with a bayonet114and the bayonet114is located at the bottom of the installation housing14, and the other first clamping piece111is provided with a card slot115and the card slot115is located at the top of the installation housing14; an elastic button116is movably provided in the installation housing14. The elastic button116includes a pressing part and a spring. The pressing part is arranged on the top end of the spring. The bottom end of the spring is in contact with the first clamping piece111provided with the bayonet114. A first peeling knife117is provided at the lower end of the elastic button116and the first peeling knife117is inserted into the bayonet114. A second peeling knife118is disposed in the fixed installation groove15and is inserted into the card slot115, and the cutting edges of the first peeling knife117and the second peeling knife118are in contact with each other.

Specifically, when the wire needs to be stripped, the end of the wire that needs to be stripped is stuck into the cutting edges of the first peeling knife117and the second peeling knife118, then press the elastic button116downward again, and the first peeling knife117moves downward to peel the end of the wire. After the peeling is completed, the elastic button116is released, and the elastic button116is reset, driving the first peeling knife117to return to its original position, and then the stripped end of the wire is taken out.

Furthermore, in order to meet the different needs of users, please refer toFIG.9. The first peeling knife117and the second peeling knife118are respectively provided with a plurality of tangent grooves119with different diameters along the length direction.

Specifically, by providing a plurality of tangent grooves119with different diameters, wires with different wire specifications can be stripped, thereby improving the practicality of the wire stripping structure.

Furthermore, in order to adapt to the different needs of users, please refer toFIG.10, one side of the second crimping module5facing the first crimping module4is recessed to form clamping grooves51of different diameters; one side of the first crimping module4facing the second crimping module5is equipped with protrusions41of different sizes, and the protrusions41are one-to-one corresponding to the clamping grooves51.

Specifically, the diameter specifications of wires corresponding to different clamping grooves51are different, so that the first crimping module4and the second crimping module5can be applied to wires of various specifications. Combined with the replaceable characteristics of the first crimping module4and the second crimping module5, it can adapt to more wire specifications.

Above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modification, equivalent replacement and improvement made within spirit and principle of the present disclosure should be included in protective scope of the present disclosure.
