DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] like Figures 1 to 3 As shown, the structure of a lock 1 of this embodiment includes a lock seat 11, a pull ring 12, a lock core 13 and an elastic member 14.

[0031] The pull ring 12 is installed on the top of the lock seat 11 so that the pull ring 12 can be pulled and lifted.

[0032] The lock seat 11 is provided with a lock core slot 111 , the front top of the lock core slot 111 has an upper through hole 112 connected to the top of the lock seat 11 , and the front side of the lock core slot 111 has a side through hole 113 connected to the outside.

[0033] The lock core 13 includes a sliding body 131, a sealing shaft 132 and a locking tongue portion 133 which are arranged in sequence. The sliding body 131 can be slid back and forth and limited in the lock core slide groove 111. The sealing shaft 132 can be slid back and forth and pass through the side through hole 113. The locking tongue portion 133 is located outside the side through hole 113.

[0034] The elastic member 14 is disposed inside the lock seat 11 and provides elastic force for the lock core 13 to slide forward.

[0035] The front end of the pull ring 12 is hinged above the upper through hole 112. After the rear end of the pull ring 12 is lifted, the front end of the pull ring 12 rotates and extends into the upper through hole 112 to control the lock core 13 to overcome the elastic force and move backward.

[0036] An elastic sealing structure 15 is provided between the sealing shaft 132 and the side through hole 113 to provide waterproof isolation between the locking tongue portion 133 and the sliding body 131 .

[0037] By this, by setting the pull ring 12, the pull ring 12 can form a lever with the front end hinged part as the fulcrum, and after the rear end of the pull ring 12 is lifted, the front end of the pull ring 12 can be driven to control the lock core 13 to slide backward along the lock core groove 111 with little effort, and due to the sliding limit and guiding function of the lock core groove 111, the lock core 13 can be prevented from tilting during the sliding process, so that the sealing shaft 132 can slide along the axis of the side through hole 113 and the elastic sealing structure 15, and the friction between the sealing shaft 132 of the lock core 13 and the elastic sealing structure 15 can be reduced, so that the sliding resistance of the lock core 13 is small, so as to facilitate the movement of the lock tongue part 133, so as to facilitate the panel opening and closing locking described below.

[0038] Specific as Figure 2 , Figure 3 and Figure 5 As shown, a push block 1311 protrudes from the top of the front end of the sliding body 131, and the push block 1311 can reciprocate in the upper through hole 112.
