The terms used in the specification of the present application are only for the purpose of describing specific embodiments, and are not used for limiting the present application. As used in this specification, the term “and/or” includes any and all combinations of one or more of associated listed items.

In addition, the technical features involved in the different embodiments of the present application described below may be combined with each other as long as there is no conflict with each other.

As shown inFIG.2toFIG.4, a belt buckle900provided by one of the embodiments of the present application includes a female buckle100and a male buckle200. The female buckle100may be fastened to the male buckle200, and the female buckle100is used to connect to one end of a lace. The male buckle200is used to connect to the other end of the lace.

The female buckle100includes a base110, a cover plate120, and an elastic member130. The base110is mounted to fit the cover plate120, and the elastic member130is arranged on one side of the cover plate120facing towards the base110, wherein the cover plate120can swing relative to the base110. One end of the cover plate120is pressed so that the elastic member130and the base110press each other, and the other end of the cover plate120swings in a direction away from the base110.

According toFIG.5toFIG.7, the base110includes a bottom plate111, a first side plate112, a second side plate113, and a connecting piece114. Both sides of the bottom plate111are connected to the first side plate112and the second side plate113respectively to form the insertion slot115. Two ends of the connecting piece114are respectively connected to the first side plate112and the second side plate113, end portions of the connecting piece114and the bottom plate111are arranged at an interval, and the connecting piece114is used for winding the lace.

In some embodiments, the first side plate112and the second side plate113are in a round arch shape, and when the cover plate120covers the base110, the ends of the first side plate112and the second side plate113away from the male buckle200are arranged at a distance from the cover plate120, the cover plate120is pressed, and the cover plate120is movable in a direction close to the bottom plate111, so as to press the elastic member130.

In some embodiments, the side walls of the first side plate112and the second side plate113are respectively provided with a first position-limiting slot1121and a second position-limiting slot1131, and the first position-limiting slot1121and the second position-limiting slot1131are symmetrically arranged. It is understandable that the first position-limiting slot1121and the second position-limiting slot1131may be in a circular shape or an arch shape, and of course, may also be in other shapes. Preferably, the first position-limiting slot1121and the second position-limiting slot1131are in an arch shape.

In some embodiments, ends of the first side plate112and the second side plate113close to the male buckle200extend outward to form a first extension portion1122and a second extension portion1132, respectively.

In some embodiments, one end of the bottom plate111close to the male buckle200extends outward and forms a guide piece1111.

In some embodiments, in order to enhance the strength of the female buckle100, the first side plate112partially extends in a direction towards the second side plate113to form a first supporting plate1123, and the second side plate113partially extends in a direction towards the first side plate112to form a second supporting plate1133, the first supporting plate1123and the second supporting plate1133are arranged symmetrically at an interval, and the first supporting plate1123and the second supporting plate1133are both located on one side of the base110away from the male buckle200. It is understandable that when the cover plate120is subjected to an external force, it swings towards the bottom plate111and presses the elastic member130. After the cover plate120swings by a certain angle, the cover plate120abuts against the first supporting plate1122and the second supporting plate1132, so as to prevent the cover plate120from breaking the elastic member130after subjected to the force.

In some embodiments, the base110further includes a guard rod116, the first side plate112and the second side plate113extend outward towards one end away from the bottom plate111and are connected to both ends of the guard rod116, and the guard rod116is located on one side of the base110away from the male buckle200.

Referring toFIG.7andFIG.8, one end face of the cover plate120is partially stretched outward to form a protrusion121, a first guide block122, and a second guide block123. The first guide block122and the second guide block123are arranged at an interval so that a channel is formed between the first guide block122and the second guide block123. The protrusion121is located between the first guide block122and the second guide block123. Preferably, one side of the protrusion121transitions from the end portion of the cover plate120to the side where the elastic member130is located, so as to form an arc surface1211.

In some embodiments, both the first guide block122and the second guide block123are higher than the protrusion121. Of course, the first guide block122and the second guide block123may also be as high as the protrusion121. In this embodiment, both the first guide block122and the second guide block123are higher than the protrusion121.

Further, the cover plate120is further provided with a supporting block124, the supporting block124is accommodated in the channel, two ends of the supporting block are respectively connected to the first guide block122and the second guide block123, and the supporting block124is located between the protrusion121and the elastic member130.

Further, the cover plate120is further provided with a plurality of ribbed plates125, one side of the ribbed plate125is connected to one side of the supporting block124, and the other side of the ribbed plate125is connected to an end face of the cover plate120.

In some embodiments, one side of the first guide block122away from the second guide block123is provided with a first position-limiting block126, one side of the second guide block123away from the first guide block122is provided with a second position-limiting block127, and the first position-limiting block126and the second position-limiting block127are symmetrically arranged.

The elastic member130is arranged at one end of the cover plate120and is located at one end of the first guide block122or the second guide block123away from the protrusion121. In this embodiment, the elastic member130is an elastic sheet bent in a direction away from the protrusion121, one end of the elastic sheet is connected to the cover plate120, and the other end is used for abutting against the base110. In other embodiments, the elastic member130may also be a spring, one end of the spring is fixedly connected to the cover plate120, and the other end of the spring is used for abutting against the base. Of course, the elastic member may also be another structure, as long as when the cover plate120is pressed, one end of the cover plate120may press the elastic member130and the other end of the cover plate120is lifted.

When the base110is mounted to fit the cover plate120, the first position-limiting block126and the second position-limiting block127extend into the first position-limiting slot1121and the second position-limiting slot1131, respectively. The first position-limiting block126and the second position-limiting block127rotate synchronously in the first position-limiting slot1121and the second position-limiting slot1131respectively, so that the two ends of the cover plate120swing relative to the base110. The other end of the elastic member130abuts against the bottom plate111. When the cover plate120is pressed to close to one side of the elastic member, the elastic member130presses the bottom plate111, and the side of the cover plate120away from the elasticity lifts in a direction away from the bottom plate111, so that the position of the protrusion121changes accordingly.

Referring toFIG.9andFIG.10, in some embodiments, the male buckle200includes an insertion block210and a male buckle main body220. The male buckle main body220is connected to the insertion block210. One end of the insertion block210is recessed inward to form a recess211, and the insertion block210is provided with an inclined surface212. Specifically, when the male buckle200is fitted with the female buckle100, the insertion block210is inserted into the insertion slot115, and the protrusion121extends into the recess211, so that the female buckle100and the male buckle200are fastened together.

In some embodiments, the male buckle main body220includes an opening frame221, and the opening frame221includes a main frame block2211, a first sub-frame block2212, and a second sub-frame block2213. Two ends of the main frame block2211are respectively connected to ends of the first sub-frame block2212and the second sub-frame block2213, respectively. The other ends of the first sub-frame block2212and the second sub-frame block2213respectively extend towards a middle closing direction to form a first extension block2214and a second extension block2215. Two side surfaces of the insertion block210are respectively connected to the first extension block2214and the second extension block2215.

Further, the male buckle main body220further includes a connecting rod2216, and the first sub-frame block2212and the second sub-frame block2213extend to one end to form a first abutting block2217and a second abutting block2218. Two ends of the connecting rod2216are respectively connected to the first abutting block2217and the second abutting block2218.

Specifically, during use, when the insertion block210is inserted into the female buckle100towards the channel, the protrusion121abuts against the inclined surface212and moves along the inclined surface212. The protrusion121is gradually lifted by the insertion block210. Limited by the first position-limiting slot1121and the second position-limiting slot1131, the first position-limiting block126and the second position-limiting block127rotate in the slot. The side of the cover plate120close to the elastic member130downward-presses the elastic member130towards the bottom plate111. After the protrusion121extends into the recess211, the elastic member is restored from the deformation. The side of the cover plate120close to the male buckle200moves in the direction towards the base110, and the cover plate120returns to its original position, thereby realizing fastening together of the male buckle200and the female buckle100.

It is understandable that, in order to facilitate the docking of the female buckle100and the male buckle200, when the insertion block210extends into the insertion slot115, the guide piece1111slides tightly close to a bottom surface of the insertion block210away from the inclined surface212. When the first extension block2214and the second extension block2215respectively abut against end portions of the first side plate112and the second side plate113, the protrusion121is exactly embedded in the recess211. At this moment, the two ends of the guide piece1111respectively abut against the first extension block2214and the second extension block2215. The first abutting block2217abuts against the first extension portion1122and the end portion of the cover plate120, and the second abutting block2218abuts against the second extension portion1132and the end portion of the cover plate120. The above structure guarantees the tight fit between the female buckle100and the male buckle200.

On the other hand, when the cover plate120is pressed to close to one side of the elastic member130, the elastic member130and the base110press each other, and the other side of the cover plate120will be lifted in the direction away from the bottom plate111. After the elastic member130is pressed to a certain degree, the protrusion121is released from the recess211, and at this moment, the male buckle200is pulled in the direction away from the female buckle100, and the fastening relationship of the male buckle200and the female buckle100is released.

Through the structure, the male buckle200only needs to use the insertion block210inserted into the insertion slot in the female buckle100, and the fitted mounting of the female buckle100and the male buckle200can be quickly realized. When it is necessary to release the fastening relationship between the female buckle100and the male buckle200, the separation of the two may be achieved by pressing the cover plate120and drawing and pulling the male buckle200. Therefore, the docking and separation of the female buckle100and the male buckle200are convenient and fast.

The belt buckle900provided by the embodiments of the present application includes: a female buckle100, including a base110and a cover plate120, an insertion slot115being provided in the base110, the cover plate120being mounted on the base110, the cover plate120being provided with a protrusion121, the cover plate120being rotatable relative to the base110, and the female buckle100being used to connect to one end of a lace; a male buckle200, including an insertion block210and a male buckle main body220, the male buckle main body220being connected to the insertion block210, a recess211being provided in the end of the insertion block210facing towards the cover plate120, the male buckle200being used to connect to the other end of the lace, wherein when the insertion block210is inserted into the insertion slot115, and the protrusion121extends into the recess211, the female buckle100and the male buckle200are fastened together; and an elastic member130arranged on the end of the cover plate120away from the male buckle200. Therefore, when the cover plate120is pressed, one end of the cover plate120moves towards the base110, the elastic member130presses the base110, and the other end of the cover plate120lifts in the direction away from the base110, so as to cause the protrusion121to separate from the recess211, which is more convenient in use. Meanwhile, after a front end portion of the insertion block210is broken, as long as the recess211still exists, the female buckle100and the male buckle200can still fit each other.

As shown inFIG.11, a belt (not shown) provided by another embodiment of the present application includes the belt buckle900of the above embodiment and a lace (not shown), one end of the lace is connected to the female buckle, and the other end of the lace is connected to the male buckle.

It is understandable that one end of the lace may be tied to the connecting piece114of the female buckle100, and of course may also be tied to other positions of the female buckle100. In this embodiment, the lace is tied to the connecting piece114. Similarly, the other end of the lace may be tied to the connecting rod2216or other positions of the male buckle200, such as the main frame block2211. Preferably, the other end of the lace is tied to the connecting rod2216.
