Description

Technical Field

[0001] The utility model belongs to the technical field of locks, in particular to a waterproof lock. Background Art

[0002] A lock is a device that serves a sealing function, which includes a lock, key and other accessories. In addition to being opened by a key, a lock can also be opened by light, point, magnetism, sound and fingerprint commands. Its functions are becoming more and more diverse. For some key locks used outdoors, since their waterproof effect is relatively general, when the lock is opened under extremely harsh conditions, external rainwater can easily splash onto the lock and penetrate into the lock through the keyhole, making the lock prone to rust and unable to be opened.

[0003] A Chinese patent document (application publication number CN220687008U) discloses a lock having a waterproof structure, which includes a lock shell and a waterproof component. A connecting seat is provided in the lock shell, and a first groove is provided on the connecting seat. The first groove has a through hole for facilitating the installation of an external lock body. The waterproof component includes a first U-shaped groove provided along the side wall of the first groove and a protective cover movably connected to the connecting seat that can be opened and closed.

[0004] It can be seen that the patent document cited above also has the same problem. The waterproof effect of its lock is relatively general. When the lock is opened under extremely harsh conditions, after the protective cover is rotated downward to open, the external rainwater can easily splash onto the lock, and then penetrate into the lock through the keyhole, making the lock easy to rust inside and unable to open the lock. Utility Model Content

[0005] The purpose of the present utility model is to provide a waterproof lock to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a waterproof lock, comprising a lock shell, a lock hole for opening and closing the lock is provided in the middle of one side of the inner wall of the lock shell, two fixing blocks are installed on the inner top end of the lock shell, and a protective plate is commonly provided on the opposite sides of the two fixing blocks, a connecting component is provided inside the protective plate, and two auxiliary plates are connected to the protective plate through the connecting component, sealing strips are installed at both ends of one side of the protective plate, and a fixing component is provided at the bottom end of the protective plate.

[0007] As a preferred embodiment, water guide strips are installed on the outer sides of the top inner side of the lock housing.

[0008] As a preferred embodiment, the connecting assembly includes a connecting shaft, a transmission gear is installed on the outer wall of the connecting shaft, and racks are meshed at the upper and lower ends of the tooth edge of the transmission gear. The opposite ends of the two racks are fixedly connected to the opposite sides of the two auxiliary plates respectively, and an elastic block is installed on the back of one of the racks.

[0009] As a preferred implementation, the fixing assembly comprises a buckle, an outer wall of the buckle is provided with a clamping block, and the top end of the clamping block is fixedly connected with the bottom end of the lock shell.

[0010] As a preferred implementation, the outer walls of the two auxiliary plates are respectively connected with the two sides of the protection plate.

[0011] As a preferred implementation, two flow guide grooves are formed at the two ends of one side of the inner wall of the lock shell, and the inner walls of the two flow guide grooves are respectively connected with the outer walls of the two sealing strips.

[0012] As a preferred implementation, the opposite sides of the two auxiliary plates are respectively provided with fixing grooves, and the inner walls of the two fixing grooves are respectively connected with the other ends of the two racks.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The waterproof lock benefits from the design of the protection plate, the auxiliary plate and the connecting assembly. The protection plate is opened in an upward rotating manner. When the lock is opened under extreme harsh conditions, this manner can shield the upper part of the lock hole, avoid rainwater from splashing on the lock and penetrating into the inside of the lock through the lock hole, and prevent the inside of the lock from being rusted and the lock from being unable to be opened, thereby prolonging the service life of the lock. Meanwhile, the auxiliary plate can be unfolded outward through the connecting assembly, so that the protection area is increased when the protection plate is opened, and the waterproof effect is further improved.

[0015] The water guide strip is arranged on the lock shell and is in an inward bending shape. When the rainwater at the top end of the outer wall of the lock shell flows downward, the rainwater is directly guided outward, and the rainwater is prevented from flowing to the side of the lock hole on the inner wall of the lock shell, thereby improving the waterproof effect of the lock.
