Description

Technical Field

[0001] The utility model relates to a lock, in particular to a lock body structure. Background Art

[0002] Locks refer to devices that have a sealing function, including locks, keys and their accessories. It is generally interpreted as "a seal that can only be opened with a key". In addition to being opened with a key, locks can also be opened with instructions such as light, electricity, magnetism, sound and fingerprints. Locks are not only protective equipment, but also have the functions of "management" and "decoration". There is also a kind of etiquette in international exchanges, which uses symbolic "keys" as a token of friendship. Most of the existing products are external handle structures, which are set on the surface and occupy a certain space when opening and closing. Although there are some hidden handle products, most of them are too simple in structure, easy to open by mistake, and not stable enough. For example, flip-top products are designed with torsion springs or general spring structures, and are matched with buckles or card points to limit and maintain relative states. However, after long-term use, they are prone to failure of the elastic part or local wear and tear and cannot be operated smoothly. Even if high-strength elastic materials are used, it cannot be completely avoided, which affects daily use and increases production costs. High elasticity may also hurt users. Utility Model Content

[0014] like Figure 1-Figure 4As shown, a lock body structure comprises a hinged lock box 1 and a lock cover 2, wherein the lock box 1 is provided with a chamber 3 for installing parts, wherein the chamber 3 is provided with a base 4, and the base 4 is connected to the lock box 1 as a whole. The base 4 is provided with a movable toothed member 5 and an elastic member 6 combined therewith on opposite sides, and an open movable groove 7 is provided on the base 4, wherein a slider 8 and a bracket 10 for hingedly connecting the slider 8 are provided in the movable groove 7, and an elastic member 9 for elastic reset is provided between the movable groove 7 and the slider 8, and the bracket 10 and the lock cover 2 are hingedly assembled, and an engaging portion 11 for engaging and limiting with the toothed member 5 is provided on the lock cover 2, wherein the slider 8 is linearly reciprocated by the elastic member 9, and the lock cover 2 is elastically locked by the elastic member 9. A knob is provided on the surface of the lock box 1, and it should be pointed out that the outer door does not have such a knob, and the lock core at the knob and the elastic member 9 can be linked to control the switching of the locking state, but it is by no means limited to this. In this embodiment, the lock cover 2 and the lock box 1 are hinged and rotated through the connecting shaft 13, and the toothed member 5 and the meshing part 11 play a damping role. Specifically, the toothed member 5 can be tightly assembled, but can still rotate under a large external force. There are many implementation methods and are not limited to this. The elastic member 16 makes the lock cover 2 have a tendency to open elastically, and the toothed member 5 plays a reverse damping effect. The design of the bracket 10 plays a role similar to an active joint, which can transmit the action of the elastic member 29 to the lock cover 2 and adjust the direction of action, that is, the lock cover 2 has an elastic locking tendency, so that the lock cover 2 is kept at a specified position of the lock box 1.

[0015] A connecting shaft 13 is provided between the lock box 1 and the lock cover 2, and the elastic member 1 6 is a torsion spring sleeved on the connecting shaft 13, and the two ends of the elastic member 1 6 elastically abut the lock cover 2 and the lock box 1 respectively. The connection and assembly method here is simple, reliable, and convenient for assembly. The elastic member 2 9 includes a swing arm driven to rotate by a torsion spring, and a linkage column 14 is provided on the slider 8, and a linkage groove 15 is provided on the swing arm to cooperate with the linkage column 14. This is one embodiment, and the rotation direction of the elastic member 2 9 is perpendicular to the installation direction of the linkage column 14, and there is no need for too complicated design. The bracket 10 is a concave structure, and the bracket 10 is also provided with a hinge shaft 16 that passes through the slider 8. The central section of the bracket 10 is cylindrical, and the central section of the bracket 10 is also provided with a connecting block 17. A clamping groove 18 for clamping the central section of the bracket 10 and a screw hole 19 for threaded connection are provided between the connecting block 17 and the lock cover 2. The central section of the bracket 10 is equivalent to being fixed on the lock cover 2 by the connecting block 17, and a screw hole 19 is also provided to strengthen the connection and fixation, but it does not limit its relative rotation. The base 4 is provided with a protruding positioning block 20, and the lock cover 2 is provided with a positioning groove 21 corresponding to the shape and size of the positioning block 20 to enhance the positioning effect during locking. It should be pointed out that the slide moves relatively forward and backward, and the lock cover 2 is pulled close to the lock box 1 through the bracket 10 to ensure the locked hidden state, which will not be elaborated and limited in detail here.
