Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a lock body with low friction and smooth unlocking. Background Technology

[0002] Car door locks are one of the important components of a car body. They have a variety of functions and operating methods, and are mainly divided into three types: mechanical locks, ordinary electric locks and super locks. Mechanical locks mostly use mechanical locking plates to open and lock the lock body.

[0003] However, existing lock bodies have certain defects in actual use. The rotating connecting shaft is still connected by rivets, which can easily cause jamming or even jamming when unlocking, resulting in unsmooth unlocking. Over time, it can also cause wear and tear on the lock, affecting its service life. Utility Model Content

[0004] The purpose of this invention is to provide a lock body with low friction and smooth unlocking, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lock body with low friction and smooth unlocking, comprising a lower housing and an upper housing. A locking plate is provided on the lower housing via a rotating assembly. A first slot and a second slot are sequentially formed on the locking plate. A locking groove matching the locking plate is formed on the lower housing. An auxiliary assembly is provided at one end of the lower housing near the locking groove, and a reset assembly is provided at one end of the lower housing away from the locking groove. The reset assembly matches the rotating assembly. An upper housing is provided on the lower housing.

[0006] Preferably, in order to facilitate connection and assembly, both the upper and lower housings are provided with connection holes.

[0007] Preferably, in order to facilitate rotation, opening and locking operations, reduce friction, and make the operation smoother, the rotating assembly includes a sleeve rod disposed on the lower housing and the locking plate, the sleeve rod being provided with a miniature bearing that matches the locking plate.

[0008] Preferably, in order to facilitate opening and locking operations, the rotating assembly also includes a lever mounted on the sleeve, and a rotating component is provided on the lower housing, which matches the locking plate.

[0009] Preferably, in order to facilitate the storage of potential energy and subsequent automatic reset, the lever is provided with a second mounting sleeve, and the second mounting sleeve is provided with a second torsion spring, which is matched with the rotating part.

[0010] Preferably, in order to facilitate the storage of potential energy and subsequent automatic reset, the reset component includes a mounting sleeve 1 disposed on the lower housing, and a torsion spring 1 disposed on the outside of the mounting sleeve 1, the torsion spring 1 matching the rotating component.

[0011] Preferably, in order to avoid hard contact and provide protection for locks, the auxiliary component includes a vertical rod disposed at one end of the lower housing near the locking groove, and a rubber gear post is rotatably provided on the outside of the vertical rod, the rubber gear post matching the locking plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating component, in conjunction with the reset component, allows for convenient rotation and adjustment of the locking plate, facilitating opening and locking operations. Furthermore, the use of miniature bearings instead of traditional rivets reduces sliding friction to rolling friction, resulting in smoother unlocking. After fatigue testing, the unlocking remains smooth, preventing jamming and stuck phenomena, and exhibiting good wear resistance. The auxiliary components prevent hard contact during opening and locking rotation, protecting the lock and extending its service life. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides an embodiment of a lock body with low friction and smooth unlocking, comprising a lower housing 1 and an upper housing 2. Both the lower housing 1 and the upper housing 2 have connecting holes 3, allowing for connection and assembly via screws or other means. A locking plate 5 is rotatably mounted on the lower housing 1 via a rotating assembly. The locking plate 5 has a first slot 16 and a second slot 17 sequentially formed, facilitating locking with a locking rod. The lower housing 1 also has a locking groove 6 matching the locking plate 5 (containing a locking rod, not shown in the figure; this is a mature technology and will not be elaborated upon here). A sleeve rod of the rotating assembly is welded to the lower housing 1. 10. The locking plate 5 is sleeved on the sleeve rod 10. The sleeve rod 10 is equipped with a miniature bearing 7, which can be easily changed from rotation to rolling friction, reducing friction, making unlocking smoother, and improving wear resistance. The sleeve rod 10 is equipped with a lever 4 through the miniature bearing 7, and the lower housing 1 is equipped with a rotating component 13, which matches the locking plate 5. The lever 4 is equipped with a mounting sleeve 2 14, and the mounting sleeve 2 14 is equipped with a torsion spring 2 15, which matches the rotating component 13. The lever 4 can be easily moved. With the help of the rotating component 13, the torsion spring 2 15, etc., the locking plate 5 can be rotated and adjusted, which facilitates the unlocking operation.

[0020] Please see Figures 1-4 To facilitate unlocking and avoid hard contact, the lower housing 1 is provided with a mounting sleeve 11 for a reset component. The mounting sleeve 11 is provided with a torsion spring 12. The torsion spring 12 cooperates with the rotating part 13 to facilitate unlocking. The lower housing 1 is provided with a vertical rod 8 of an auxiliary component at one end near the locking groove 6. A rubber gear column 9 is rotatably provided on the outside of the vertical rod 8 to guide and limit the locking plate 5 and avoid hard contact.

[0021] Working principle: In use, the upper housing 2 and lower housing 1 can be connected and assembled through the connecting hole 3 and screws. When locking, moving the lever 4, in conjunction with the sleeve 10 and miniature bearing 7, rotates the locking plate 5. Simultaneously, the rotating part 13 and torsion springs 12 and 15 store potential energy. The locking rod (not shown in the figure) is located in the locking groove 6. Releasing the lever 4 resets the locking plate 5 under the action of the potential energy of torsion springs 12 and 15, rotating it. The locking rod can be adjusted as needed by the... The locking bar is locked by the first slot 16 or the second slot 17. During the rotation of the locking plate 5, the rubber gear column 9 can avoid hard contact. When unlocking is required, the locking plate 5 can be rotated by moving the lever 4, which can turn out the first slot 16 or the second slot 17, thus losing the locking of the locking bar and completing the unlocking. The rotation is carried out by the miniature bearing 7, which changes from sliding friction to rolling friction, reducing the friction force and making unlocking smoother. After fatigue testing, the unlocking is smooth, avoiding jamming and jamming, and has good wear resistance.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
