DESCRIPTION OF THE EMBODIMENTS

The present application is described in further detail below with reference toFIGS. 1-8.

Embodiments of the present application provide a handle.

Referring toFIGS. 1 and 3, a handle includes a handle portion1and a rotating shaft portion2, which are used cooperatively. The rotating shaft portion2is inserted into the handle portion1. The handle portion1and the rotating shaft portion2are integrated as a whole by means of a snap-fit mounting structure, and are locked with each other by means of a press-on member3mounted inside the handle portion1. In this way, instead of a conventional screw locking manner, a snap-fitting structure and a press-on locking are cooperated, so as to improve the usage stability of the handle.

Referring toFIGS. 1 and 2, in this embodiment, the handle portion1is configured with an L-shaped structure, which includes a long side11having a flat shape and a short side12that is integrated with any end of the long side11and is formed by bending. The short side12is perpendicular to the long side11, and one end of the short side12is integrally formed with the long side11. The other end of the short side12is coaxially provided with an assembly mounting hole13. The rotating shaft portion2is coaxially inserted into the assembly mounting hole13and integrated with the short side12as a whole by means of a snap-fit mounting structure.

Referring toFIG. 3, the rotating shaft portion2includes a front section21, an intermediate section22and a rear section23which are integrally formed in sequence, and all of which have a coaxially arranged cylindrical structure. The front section21is mainly configured for a snap-fitting with the assembly mounting hole13by means of the snap-fit mounting structure. The intermediate section22includes a first section221and a second section222, both of which have a diameter greater than that of the front section21. The diameter of the first section221is greater than that of the second section222. The second section222is coaxially formed with a shaft end of the front section21. Correspondingly, a stepped groove131is formed on an inner wall of an orifice of the assembly mounting hole13. When the rotating shaft portion2is inserted into the assembly mounting hole13, a stepped limiting structure formed by the first section221and the second section222may be fitted with the stepped groove131, thereby achieving a purpose of limiting the insertion depth of the rotating shaft portion2. The diameter of the rear section23is larger than the diameter of the front section21, but slightly smaller than the diameter of the second section222, so as to lock and connect with a lock for using with the handle.

Referring toFIGS. 3 and 4, the snap-fit mounting structure includes a first snap-fit portion4integrally formed on the rotating shaft portion2, and a second snap-fit portion5integrally formed on a hole wall of the mounting hole. The first snap-fit portion4has a ring-shaped structure integrally formed along the periphery of a shaft end of the front section21that is away from the intermediate section22. Two snap-fit positions are formed on the first snap-fit portion4. In the embodiment of the present application, the snap-fit position is a snap-fit groove41that is formed on an inner side surface of a ring-shaped structure, and the snap-fit groove41is a rectangular groove. The second snap-fit portion5includes a first snap-fit block51which forms a snap-fitting with two snap-fit positions of the first snap-fit portion4. A notch42is provided on the first snap-fit portion4. When the rotating shaft portion2is inserted into the assembly mounting hole13, the first snap-fit block51may penetrate through the first snap-fit portion4via the notch42. During the rotation of the rotating shaft portion2, the snap-fitting with any of the snap-fit positions can be realized.

Referring toFIGS. 4 and 5, the number of snap-fit grooves41is set to two, and an intermediate groove43is formed at a position in the middle of the two snap-fit grooves41on the first snap-fit portion4. The two snap-fit grooves41are positioned at two opposite ends in a diameter direction of the front section21. In other words, the two snap-fit grooves41are respectively formed at positions of 0 degree and 180 degree in a circumferential direction of the front section21, and the intermediate groove43is formed at a position of 90 degree in the circumferential direction of the front section21. According to actual requirements, the user may select two snap-fit grooves41at the position of 0 degree or 180 degrees to be used cooperatively with the first snap-fit block51, so as to achieve the purpose of adaptively adjusting of the handle mounting position. The snap-fit groove41at the position of 90 degree is an intermediate transition position. Generally, when a door with the handle according to the embodiment is transported, the snap-fit groove41at the position of 90 degree is selected to be used cooperatively with the first snap-fit block51, so that the handle is arranged along the height direction of the door, thereby facilitating binding and fixing of the handle and the door.

Referring toFIG. 4, on the basis of the above embodiment, a curved section44is formed at a transition position between the intermediate groove43and the snap-fit grooves41on both sides of the first snap-fit portion4. The first snap-fit block51can smoothly rotate through the curved section44and the intermediate groove43during the rotating of the rotating shaft portion2.

Referring toFIGS. 4 and 5, one end of the first snap-fit portion4at the position of the notch42extends in the axial direction of the front section21to integrally form a transition portion45. The transition portion45further extends to integrally form a limiting snap-fit portion46. The limiting snap-fit portion46includes a ring plate461that is integrally formed by extending in the circumferential direction of the front section21. An end of the ring plate461away from the transition portion45extends in the axial direction of the front section21to integrally form a stopper462. A snap-fit groove41is formed at the other end of the first snap-fit portion4at a position of the notch42, and the snap-fit groove41is used as a boundary groove411. The boundary groove411is directly communicated with the notch42. The other snap-fit groove41is formed at a corner position where the first snap-fit portion4is connected with the transition portion45. Referring toFIG. 2, in addition to the first snap-fit block51described above, the second snap-fit portion5further includes a second snap-fit block52that is also formed on the inner wall of the assembly mounting hole13. The second snap-fit block52and the first snap-fit block51are arranged in a front-rear misalignment manner on the inner wall of the assembly mounting hole13, an included angle of which in the circumferential direction of the assembly mounting hole13is set to 90 degree. With reference toFIGS. 2 and 4, when the rotating shaft portion2is inserted into the assembly mounting hole13of the handle portion1, the first snap-fit block51snap-fits with a corresponding snap-fit groove41, and the second snap-fit block52abuts against an outer side surface of the ring plate461. When the first snap-fit block51snap-fits with the boundary groove411, the second snap-fit block52slides along the outer side surface of the ring plate461and is snap-fitted at a position where the ring plate461and the stopper462are connected, thereby preventing the first snap-fit block51from escaping from the boundary groove411on the basis that the first snap-fit block51can quickly snap-fits with the boundary groove411, and obtaining a more stable snap-fitting. Further, the handle mounting direction is quickly and conveniently adjusted and the purpose of stabilizing the snap-fitting structure is achieved.

With reference toFIGS. 2 and 4, a disengagement interval47is formed on a cylindrical surface of the front section21, which is positioned between the second section222and the stopper462. A sliding interval48is formed between the outer side surface of the ring plate461and the inner side surface of the first snap-fit portion4. When the rotating shaft portion2needs to be disassembled, the user may rotate the rotating shaft portion2such that the boundary groove411snap-fits with the first snap-fit block51, press the rear section23of the rotating shaft portion2to overcome the press-on acting force of the press-on member so that the second snap-fit block52disengages the limiting snap-fit portion46and slides along the axial direction of the front section21into the disengagement interval47, i.e., the second snap-fit block52abutting against a side edge of the second section222. Meanwhile, the first snap-fit block51is disengaged from a corresponding snap-fit position and slides along the axial direction of the front section21into the sliding interval48, i.e., the first snap-fit block51abutting against the outer side surface of the ring plate461. Then, the user rotates the rotating shaft portion2until the first snap-fit block51is in butt joint with the notch42. At this time, the rotating shaft portion2can be pulled out in a direction opposite to the pressing direction, and the first snap-fit block51can be disengaged from the notch42. When the second snap-fit block52is disengaged, it is required to rotate the rotating shaft portion2by an appropriate angle, so that the second snap-fit block52is in butt joint with the notch42and is disengaged from the notch42, thereby completing the disassembling operation of the rotating shaft portion2.

Referring toFIGS. 2 and 4, when changing the direction of the handle, different with the disassembling operation of the rotating shaft portion2, it is only required to press the rear section23of the rotating shaft portion2to separate the first snap-fit block51from a corresponding snap-fit groove41. At this time, the first snap-fit block51enters into the sliding interval48; however, the second snap-fit block52does not completely enter into the disengagement interval47. As a result, the stopper462can still function to restrict the first snap-fit block51from being disengaged form the first snap-fit portion4. The user rotates the rotating shaft portion2until the first snap-fit block51rotates to a position where it is in butt joint with another snap-fit position, and then releases the rotating shaft portion2such that the press-on member3presses on the rotating shaft portion2again and the first snap-fit block51snap-fits another snap-fit position. Thus, the reversing operation of the handle is completed.

With reference toFIGS. 2 and 4, on the basis of the above embodiment, an elastic member is used as the press-on member3. In this embodiment, a spring is used as the press-on member3, and the spring is sandwiched between an inner end of the assembly mounting hole13and a shaft end of the front section21. When the first snap-fit block51snap-fits with any one of snap-fit positions, the spring can press the shaft end of the front section21toward the direction in which the rotating shaft portion2is disengaged from the assembly mounting hole13, so that the rectangular groove and the first snap-fit block51form a stable snap-fit locking.

With reference toFIGS. 2 and 3, a positioning hole211is coaxially formed on an end surface of the front section21, and correspondingly, an inserting hole132is formed on an inner end of the assembly mounting hole13. An end of the spring and the corresponding positioning hole211or inserting hole132form a positioning and plug-in fitting. A positioning block6may be embedded in the positioning hole211or the inserting hole132. The positioning block6can be fitted to the end of the spring in a sleeving manner, thereby achieving the purpose of stably mounting the spring and obtaining a relatively stable press-on force.

The operation principle of embodiment 1 will be described below.

When the assembling operation is performed, a user aligns the notch42and the second snap-fit block52on the rotating shaft portion2, and rotates the rotating shaft portion2by an angle after the second snap-fit block52passes through the notch42so that the first snap-fit block51passes through the notch42, and then rotates the rotating shaft portion2so that the first snap-fit block51rotates into the sliding interval48until the first snap-fit block51is in butt joint with a corresponding snap-fit groove41; at this time, releases the rotating shaft portion2such that the rotating shaft portion2moves towards a direction to be separated from the assembly mounting hole13under the action of the press-on member3until the first snap-fit block51snap-fits with a corresponding snap-fit groove41and the second snap-fit block52abuts against the ring plate461or is snap-fitted to a position where the ring plate461and the stopper462are formed.

When the disassembling operation is performed, the user presses the rear section23of the rotating shaft portion2in order to overcome the pressing force of the press-on member3so that the second snap-fit block52is disengaged from the limiting snap-fit portion46and slides along the axial direction of the front section21into the disengaging interval47, and at the same time, the first snap-fit block51is disengaged from a corresponding snap-fit position and slides along the axial direction of the front section21into the disengagement interval48. Then, the user rotates the rotating shaft portion2until the first snap-fit block51is in butt joint with the notch42. At the same time, the rotating shaft portion2can be pulled out in the direction opposite to the pressing direction. The first snap-fit block51can be disengaged from the notch42. When the second snap-fit block52is disengaged, it is required to rotate the rotating shaft portion2by an appropriate angle, so that the second snap-fit block52is in butt joint with the notch42and disengaged from the notch42, thereby completing the disassembling operation of the rotating shaft portion2.

When changing the direction of the handle, the rear section23of the rotating shaft portion2is pressed, so that the first snap-fit block51is separated from the corresponding snap-fit groove41. At this time, the first snap-fit block51enters into the sliding interval48, and however, the second snap-fit block52does not completely enter into the disengagement interval47. As a result, the stopper462can still function to restrict the first snap-fit block51from being disengaged from the first snap-fit portion4. The user rotates the rotating shaft portion2until the first snap-fit block51rotates to a position where it is in butt joint with another snap-fit position. Then, the rotating shaft portion2is released, and the press-on member3presses on the rotating shaft portion2again such that the first snap-fit block51snap-fits with another snap-fit position. In this way, the direction of the handle is changed.

With reference toFIGS. 6 and 7, a handle differs from Embodiment 1 in that, the first snap-fit portion4and the second snap-fit portion5are formed at different positions. In this embodiment, the first snap-fit portion4is formed on the inner wall of the assembly mounting hole13of the handle portion1, while the second snap-fit portion5is formed on the cylindrical surface of the front section21of the rotating shaft portion2.

An embodiment of the present application further provides a lock structure with a handle as described above.

With reference toFIGS. 1 and 8, a lock structure includes a lock cylinder8that is operated in conjunction with the described handle via a connecting portion7. The connecting portion7has a disc-shaped structure, and is rotatably mounted on a door panel. The connecting portion7is in locking connection with the rotating shaft portion2of the handle via a locking member9. A screw is used as the locking member9. Correspondingly, the rear section23of the rotating shaft portion2is provided with an inserting end232, the shaft end of the inserting end232is coaxially provided with a threaded mounting hole231, and the locking member9is inserted into the connecting portion7and then forms threaded connection and locking with the threaded mounting hole231. On this basis, the inserting end232has a square structure, and forms a positioning and insertion fit with the connecting portion7, so as to improve the accuracy of connecting when the connecting portion7and the handle are mounted.

The above description is only preferred embodiments of the present application and is not intended to limit the protection scope of the present application. Therefore, all equivalent changes of the structure, shape or principle according to the spirit of the present application should be all included in the protection scope of the present application.
