DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. EMBODIMENT
[0027] As shown in Figs. 1 to 4 The novel lock catch of the latch lock comprises a fixing member 1 with an inner cavity, a base 3 connected to the bottom of the inner cavity of the fixing member through a shaft 2, a movable member 5 rotatably connected to the inner cavity of the fixing member through a pin shaft 4, and a torsion spring 6 arranged between the fixing member and the movable member. The torsion spring is sleeved on the pin shaft and abuts against the inner walls of the fixing member and the movable member at both ends. In the embodiment, the fixing member, the base and the movable member are metal structures. The fixing member, the base and the movable member are conventional structures of the prior art, which are simply applied, so they are not described in detail. The torsion spring is mainly used for storing energy when the movable member is pressed, so as to quickly pop open when unlocking.
[0028] In addition, in the embodiment, a lock catch 8 is rotatably connected to the upper part of the inner cavity of the fixing member through a connecting shaft 7. An abutting recess 9 is arranged on the outer side wall of the lock catch, and a lock catch recess 10 is arranged on the inner side wall of the lock catch. The abutting recess cooperates with the abutting protrusion of the base, and the lock catch recess cooperates with the movable member. When the movable member is locked, it is clamped into the lock catch recess, and the lock catch rotates around the connecting shaft and makes the abutting protrusion of the base clamped into the abutting recess of the lock catch, so as to ensure the stability and reliability of the locking position. The connecting shaft and the pin shaft are arranged on both sides of the center line of the inner cavity of the fixing member. A reset spring 11 is arranged between the movable member and the lock catch. The reset spring is sleeved on the connecting shaft, and both ends of the reset spring are connected to the movable member and the lock catch. When the lock catch is locked, the reset spring stores energy, and when the movable member is opened, the lock catch can rotate within a certain angle range and separate from the base, so as to ensure the stability of the effectiveness of subsequent locking.
[0029] In practical application process, the inner wall upper portion of the base is provided with a stop protrusion 12; in use, the stop protrusion is clamped into the stop recess of the locking piece to limit. When locking, the locking piece can be limited by the base, and the stability and reliability of the connection with the movable piece can be improved.
[0030] In practical application process, the lower portion of the locking piece is bent to form a protrusion 13; the lower portion of the movable piece is inclined to form a boss 14, and the boss is provided with a clamping protrusion 15; in assembly, one end of the reset spring is fixed with a ring 16 and the other end is bent to form a transverse rod 17; the protrusion is clamped into the ring, and the transverse rod is positioned on the top surface of the clamping protrusion. Through the above structure, the effectiveness and stability of the connection between the reset spring and the locking piece and the movable piece can be ensured.
[0031] In practical application process, the end of the movable piece away from the pin shaft is rotatably connected with a roller 18 through a circular shaft. The width of the roller is less than the width of the inner cavity of the fixed piece. The roller is a conventional structure of the prior art, which is simply applied, so it is not described in detail. The main function is to guide, ensure the effectiveness and reliability of unlocking or locking.
[0032] The utility model has the positive effect: the utility model discloses the structure setting is reasonable, is provided with the locking piece, and cooperates reset spring and torsion spring, and the whole structure is simple, and it is favorable to improve the convenience and stability of assembly, and through reset spring and torsion spring, the impact between movable piece and fixed piece can be reduced, so as to avoid damage, improve the number of opening and closing, and better positioning and locking operation can be carried out, and the use stability and service life are improved.
[0033] The standard parts used in the embodiment can be directly purchased from the market, and the non-standard structural parts according to the description can also be directly processed according to the existing technical knowledge without doubt. Meanwhile, the connection mode of each part adopts the mature conventional means in the existing technology, and the machinery, parts and equipment adopt the conventional models in the existing technology, so specific description is not made here.
[0034] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. The changes or variations extended from the essential spirit of the utility model are still within the protection scope of the utility model.
