Description

Buffer cushion positioning and mounting structure of lockset Technical Field The utility model relates to the field of locks, in particular to a buffer cushion positioning and mounting structure of a lock. Background The tool to lock is as the core safety element of the door body, and its stability and durability directly influence user experience. In the scenes such as metal frame glass door, timber, the tool to lock needs to realize the connection with the door body through the blotter usually-the blotter not only can cushion the rigid contact of lock body and door body, reduces wearing and tearing, can also assist fixed lock body and handle, avoids becoming flexible or shifting because of frequent operation leads to. In the prior art, for example, chinese patent No. CN217735110U discloses a lock structure of a metal frame glass door, in which an inner rubber pad and an outer rubber pad are used to isolate the contact surface between the lock body and the glass door, and a certain protection is provided by the soft material of the rubber pad. However, the rubber pad mounting structure in this patent still has the following significant drawbacks: 1. The rubber pad in this patent realizes preliminary fixed through "the pad falls into lock body mounting groove" and "pad laminating glass surface", after long-term use, the tool to lock handle frequently rotates the transverse stress that produces easily to lead to the rubber pad to slide or drop along the lock body surface, can't guarantee the lock body and the stable connection of the door body. 2. The binding force between the rubber pad and the glass door only depends on the friction force of the pad, and the handle is easy to sag due to gravity or rotational inertia after long-term use, so that the closing precision and the aesthetic property of the lockset are affected. Therefore, the existing installation structure of the lock cushion has the problems of poor stability, insufficient buffering and unloading force, weak sagging resistance and the like, and cannot meet the requirement of users on long-term stable use of the lock, so that a structure-optimized lock cushion positioning and installation structure is needed to solve the defects. Disclosure of Invention The technical problem to be solved by the utility model is to provide a buffer pad positioning and mounting structure of a lockset aiming at the defects of the prior art. In order to achieve the purpose, the technical scheme is that the buffer cushion positioning and mounting structure of the lockset comprises a lock cover and a buffer cushion, wherein at least one group of positioning grooves and positioning blocks which are correspondingly arranged are arranged between the buffer cushion and the lock cover, and the positioning grooves and the positioning blocks are in plug-in fit to form a limiting structure. By adopting the technical scheme, through corresponding setting up constant head tank and locating piece between blotter and locking closure, utilize the grafting cooperation of both to form physical limit structure, the shape of constant head tank and locating piece, the size is mutually adapted, when blotter and locking closure are assembled, the locating piece inserts in the constant head tank, the cell wall forms the block, limit structure refers to restriction blotter and locking closure's horizontal slip (if along the horizontal or longitudinal movement on locking closure surface) and rotary displacement, thereby be relatively stable whole with blotter and locking closure fixing, through the grafting cooperation of constant head tank and locating piece, the relative motion of blotter and locking closure has been directly restrained, the blotter that has avoided the transverse stress that produces because of the frequent rotation of handle shifts or drops, the connection steadiness of blotter and locking closure has been showing to be promoted, simultaneously, this kind of stable connection structure has ensured the reliable fixation of lock body and door body, effectively reduced the handle sagging problem because of not hard up arouses, thereby the whole stability in use and the durability of tool to lock have been promoted. The buffer cushion positioning and mounting structure of the lock can be further arranged that the buffer cushion comprises a spacer arranged on the inner side of the lock cover and a pad attached to the surface of the side wall of the lock cover, and the spacer is connected with the pad and the joint is in a step-shaped arrangement. By adopting the technical scheme, the buffer pad is designed into the two parts of the buffer pad and the pad, the buffer pad is used for being installed on the inner side of the lock cover, the buffer pad is attached to the side wall surface of the lock cover, the buffer pad and the pad are connected through the step-shaped connecting part, the step-shaped structure is formed by the buffer pad and the pad at the connecting part, th
