Abstract
Description

[0001] The utility model relates to the technical field of lock tongue resetting, in particular to a novel lock tongue resetting structure. Background Art
[0002] The lock tongue is an important component in the lock. When the lock is working, the lock tongue will be stuck on the "door frame" to complete the locking work. When in use, the lock tongue also needs to be reset through the reset structure. The traditional reset structure is achieved by independently equipping a torsion spring or a compression spring. That is to say, the lock tongue is equipped with a torsion spring or a compression spring separately, and the stop claw is also equipped with a torsion spring or a compression spring separately. The structure is relatively complicated, and the two torsion springs have different degrees of elasticity consumption during long-term use, making it difficult for the lock tongue and the stop claw to achieve close matching in their active work, and errors are prone to occur, resulting in poor reset accuracy of the lock tongue, affecting the user's normal use in the later stage.

DETAILED DESCRIPTION
[0029] The following is a combination of the appended examples of the present invention Figure 1-7 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example
[0030] A novel lock tongue reset structure includes a shell 1, and mounting holes 2 are provided at both ends of the inner bottom of the shell 1. A rotating shaft assembly 3 is inserted into the inside of the two mounting holes 2. The surfaces of the two rotating shaft assemblies 3 are respectively sleeved with mutually adapted lock tongues 4 and adapters 5. A retaining spring 6 is hung between the lock tongue 4 and the adapter 5. A protrusion 7 that is adapted to the retaining spring 6 is fixedly connected to one side of the top of the adapter 5, and a protrusion 8 that is adapted to the retaining spring 6 is embedded on one side of the lock tongue 4.
[0031] The specific usage process is as follows: an opening is provided on one side of the shell 1 for the lock head to be inserted when in use. When working, the lock head is inserted from the opening and then touches the lock tongue 4 first. The lock tongue 4 is squeezed by the lock head and will first rotate to the side away from the adapter 5. At the same time, the lock tongue 4 will also rotate on the shaft assembly 3. Because the second protrusion 8 and the first protrusion 7 are respectively integrally formed on the lock tongue 4 and the adapter 5, and the two ends of the first protrusion 7 are respectively hung on the second protrusion 8 and the first protrusion 7. In this way, when the lock tongue 4 rotates, its corresponding end will squeeze the retaining spring 6 toward one end of the adapter 5, and then the retaining spring 6 will follow and push the adapter 5 to make a corresponding rotation. It should be noted that the activity angle of the adapter 5 is limited to a certain extent by the inner wall of the shell 1. Figure 1It can be seen that a part of the adapter 5 extends to the outside of the shell 1, and the part is located on the opposite side of the end extending from the adapter port 10, so that the movement of the adapter 5 is restricted by the shell 1. At the same time, the part of the adapter 5 extending out of the inner cavity of the shell 1 can be used as an unlocking button for the user to use. Therefore, at this time, the retaining spring 6 is in a squeezed state. When the lock head is fully inserted into the opening on the shell 1, the retaining spring 6 will rebound the lock tongue 4 to its original position under the action of the retaining spring 6, and then the end of the lock tongue 4 that adapts to the lock head will be stuck on the lock head to realize the locking work, so that the reset work of the lock tongue 4 can be realized, and the reset structure of the lock tongue 4 adopts The structure of single spring connection has strong structural linkage and high structural followability, and the structure is also highly flexible when working. Each structure is highly flexible and precise, and the partial structure of the lock tongue and the stop claw is changed, and the two are connected in series with a retaining spring. The initial position has a certain pulling force, and the effect of the previous double retaining spring can also be achieved. The structure will be more compact, and the movement between the lock tongue and the stop claw will be smoother, tighter, and more synchronous. The reset accuracy is higher, and the lock sensitivity is higher, which provides convenience for the user's work. The limiting boss 9 is used to guide and limit the rotation of the lock tongue 4. When the lock tongue 4 rotates The end of the adapter 5 extends out from the housing 1 through the adapter port 10, and the diameter of the adapter port 10 is much larger than that of the end of the adapter 5, so that the end of the adapter 5 can be used for flexible activities with enough space, which provides convenience for the user's work. The shaft hole 11 and the shaft hole 2 12 are both used to install the shaft assembly 3 and the snap ring 32. Therefore, during assembly, the shaft rod 31 will be inserted into the corresponding shaft hole 11 or the shaft hole 2 12, and the snap ring 32 will also be clamped in the corresponding shaft hole 11 or the shaft hole 2 12, so that the snap ring 32 will not After it has rotated, the shaft 31 can then rotate in the retaining ring 32, ensuring that the lock tongue 4 and the adapter 5 can work normally, and also improving the flexibility and smoothness of the rotation of the lock tongue 4 and the adapter 5, providing convenience for the user's work. The support plate 14 is embedded in the bottom of the shell 1, and the shaft assembly 3 is passed through the bottom of the support plate 14 and then inserted into the shell 1 during installation. In this way, the support plate 14 can support and limit the shaft assembly 3, avoiding the shaft assembly 3 from tilting to one side during long-term use, thereby improving the flexibility and smoothness of the shaft assembly 3 during rotation, providing convenience for the user's work.
[0032] Therefore, a single retaining spring series structural design is adopted, and part of the structure of the lock tongue and the stop claw is changed. The two are connected in series with a retaining spring. The initial position has a certain pulling force, which can also achieve the effect of the previous double retaining springs. The structure will be more compact, and the movement between the lock tongue and the stop claw will be smoother, tighter, and more synchronized. The reset accuracy is higher, and the lock is more sensitive, which provides convenience for users' work.

The end of the adapter 5 extends from the shell 1 through the adapter mouth 10, and the diameter of the adapter mouth 10 is much larger than that of the end of the adapter 5, which can provide sufficient space for the end of the adapter 5 to move flexibly, providing convenience for the user's work.

[0036] Specifically, the setting of the second shaft hole 12 and the first shaft hole 11, the first shaft hole 11 and the second shaft hole 12 are both used to install the shaft assembly 3, and are also used to install the snap ring 32. Therefore, during assembly, the shaft rod 31 will be inserted into the corresponding shaft hole 11 or the second shaft hole 12, and the snap ring 32 will also be clamped in the corresponding shaft hole 11 or the second shaft hole 12, so that the snap ring 32 will not rotate, and then the shaft rod 31 can rotate in the snap ring 32, ensuring that the lock tongue 4 and the adapter 5 can work normally, and also improving the flexibility and smoothness of the rotation of the lock tongue 4 and the adapter 5, providing convenience for the user's work.
[0037] A slot 13 is formed on one side of the bottom of the housing 1 , and a support plate 14 adapted to the shaft assembly 3 is clamped inside the slot 13 .
[0038] Specifically, the arrangement of the card slot 13 and the support plate 14 is that the support plate 14 is embedded in the bottom of the shell 1, and the shaft assembly 3 is passed through the bottom of the support plate 14 and then inserted into the shell 1 during installation. In this way, the support plate 14 can support and limit the shaft assembly 3, preventing the shaft assembly 3 from tilting to one side during long-term use, thereby improving the flexibility and smoothness of the shaft assembly 3 during rotation, and providing convenience for the user's work.

[0040] Specifically, the arrangement of the shaft 31 and the retaining ring 32, the entire shaft assembly 3 is used to provide stable rotation for the lock tongue 4 and the adapter 5. When the lock tongue 4 and the adapter 5 rotate, the shaft assembly 3 will also rotate accordingly, and the ball 36 rolls close to the inner wall of the retaining ring 32 as the shaft 31 rotates, thereby improving the smoothness and flexibility of the working activities of the lock tongue 4 and the adapter 5, improving the accuracy of the resetting of the adapter 5, and improving the working stability of the lock tongue 4 and the adapter 5, providing convenience for the user's work.
[0041] The surface of the shaft 31 is provided with evenly distributed threaded holes 33 , and a bolt rod 34 is installed through the internal threads of the threaded holes 33 . A fixing bracket 35 is detachably installed at one end of the bolt rod 34 .
