Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is a schematic structural view of an embodiment of the latch of the present invention, fig. 2 is an exploded view of fig. 1, and fig. 3 is a front view of the holder. As shown in fig. 1, 2 and 3, the present invention provides a lock catch, which includes a holder 1, a fixing member 2 and a fixing groove 3.

As shown in fig. 1 and 2, the clamping frame 1 includes a first clamping member 11 and a second clamping member 12, and the first clamping member 11 and the second clamping member 12 are connected to form a clamping slot 13. In a specific use, an object to be locked can be inserted into the clamped groove 13, or the object to be locked can be inserted between the first clamping piece 11 and the first clamping piece 12.

With reference to fig. 1 and fig. 2, in this embodiment, one end of the first clamping member 11 is bent and extended to one side thereof to form a bent portion 111, the first clamping member 12 is disposed at an end of the bent portion 111 away from the end of the first clamping member 11, and the first clamping member 11, the bent portion 111 and the first clamping member 12 together form the clamping slot 13 for inserting the object to be locked. In detail, the bent portion 111 is L-shaped, one side surface of the bent portion 111 is a bottom surface of the clamping groove 13, and an end of the other side surface of the bent portion 111 is connected to the first clamping member 12.

In other embodiments, the cross section of the bent portion 111 is a straight line or a plane, that is, the first clamping member 11 and the bent portion 111 are L-shaped as a whole. The second clamping member 12 is connected to the bent portion 111 on a side opposite to the first clamping member 11, and the first clamping member 11, the second clamping member 12 and the bent portion 111 together form the clamping groove 13.

In this embodiment, the first clamping member 11 and the second clamping member 12 are fixedly connected. In other embodiments, the first clamping member 11 and the first clamping member 12 can also be hinged or integrally formed. That is, in practical operation, the above embodiment is not limited, and any mechanism or connection manner that can connect the first clamping member 11 and the first clamping member 12 with each other and can move relative to each other is feasible.

With continued reference to fig. 1 and fig. 2, in the present embodiment, a step surface structure 121 is disposed on a side of the first clamping member 12 facing the first clamping member 11. When the object to be locked is inserted into the clamping groove 13, the stepped surface structure 121 can be matched with the thickness of the object to be locked. That is, the stepped surface structure 121 can prevent the first clamping member 11 and the first clamping member 12 from being deformed due to the thickness difference of different regions of the object to be locked.

In practical implementation, the first clamping member 11 can be made of a material with high hardness. The first clamping member 12 can be made of an elastic material (having a function of restoring to shape) or a material with a hard surface and capable of rebounding by deformation, such as some plastic members, metal members, etc., capable of rebounding by deformation, can be selected. By using an elastic material or a resilient material, the ends of the first clamping member 11 and the second clamping member 12 far away from the bending portion 111 can move mutually, thereby facilitating the insertion or removal of the object to be locked.

As shown in fig. 1 and 2, a fixing member 2 is disposed on the first clamping member 11 toward the first clamping member 12, and the fixing member 2 includes a base 21, a transition portion 22, a snap groove 23, and a positioning portion 24.

With continued reference to fig. 1 and fig. 2, the base 21 is located at an end of the fixing member 2, and the fixing member 2 is connected to the first clamping member 11 through the base 21. In the present embodiment, the fixing member 2 is directly disposed on the side of the first clamping member 11 facing the first clamping member 12 through the base 21. In other embodiments, the fixing member 2 may be disposed on the first clamping member 11 in a manner of penetrating through the first clamping member 11 and being engaged and connected by the base 21. In practical application, the fixing member 2 and the first clamping member 11 can also adopt other suitable connection modes.

With continued reference to fig. 1 and fig. 2, the positioning portion 24 is located at the other end of the fixing member 2, and the positioning portion 24 can be inserted into the fixing groove 3 of the first clamping member 12.

In this embodiment, the positioning portion 24 is cylindrical, and an end portion of the positioning portion 24 on a side away from the base 21 is inwardly contracted to form a conical mesa structure, so as to be conveniently inserted into the fixing groove 3 to realize locking.

With reference to fig. 1 and fig. 2, a clamping groove 23 is circumferentially disposed on an outer surface of the fixing member 2, and the clamping groove 23 is located between the base 21 and the positioning portion 24. In specific implementation, the outer diameter of the clamping groove 23 is smaller than the outer diameters of the two adjacent sections of the clamping groove to form a clamping groove structure, so that the fixing member 2 and the fixing groove 3 can be conveniently and relatively positioned.

With reference to fig. 1, a transition portion 22 is further disposed between the clamping groove 23 and the base 21, the transition portion 22 is cylindrical, and an outer diameter of the transition portion 22 on a side away from the base 21 is gradually reduced along a direction from the base 21 to the clamping groove 23, so as to form a conical mesa structure.

In specific implementation, the fixing members 2 are made of elastic materials (having a function of restoring after deformation) or materials with hard surfaces and capable of rebounding after deformation, such as plastic members, metal members and the like capable of rebounding.

As shown in fig. 1 and 2, a fixing groove 3 is formed at a position of the first clamping member 12 corresponding to the fixing member 2, and the fixing groove 3 is engaged with the fixing member 2 to be fastened. Through the fixing piece 2 and the fixing groove 3 are clamped and connected, the first clamping piece 11 and the first clamping piece 12 can be fixed, and then the object to be locked, which is inserted between the first clamping piece 11 and the first clamping piece 12, can be locked or fixed.

As shown in fig. 1, 2 and 3, the fixing groove 3 has a projection 31, the projection 31 is disposed along the circumferential direction of the inner surface of the fixing groove 3, and the projection 31 is matched with the engaging groove 23 and can be inserted into the engaging groove 23. In detail, the fixing member 2 can be inserted into the fixing groove 3, and the boss 31 can be embedded into the clamping groove 23, so that the fixing groove 3 and the fixing member 2 can be clamped in a matched manner.

In this embodiment, the fixing groove 3 is a U-shaped groove, so that the fixing member 2 can be inserted into the fixing groove 3 and the fixing member 2 are engaged with each other.

The lock catch of the utility model can fix the first clamping piece 11 and the first clamping piece 12 by adopting the mutual matching of the fixing piece 2 and the fixing groove 3, thereby realizing the relative fixing effect on the object between the first clamping piece 11 and the first clamping piece 12; furthermore, the lock catch of the utility model has the advantages of reasonable structure, strong practicability and high market popularization value.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
