When the butterfly column 12322 moves to the positioning point b12312, under the action of the positioning point b12312, the locking rotating block guide rail 1 2324 is stuck on the positioning point b, the locking rotating block 1232 stops moving outward, the other end of the butterfly column 12322 rotates until the butterfly column 12322 slides into the locking mechanism guide groove 12314, the locking rotating block 1232 drives the slider 13 to move outward, and at the same time, the buckle plate 14 rotates under the action of the slider 13, the base trumpet 121 and the buckle plate return spring 144, the lower end of the buckle plate 14 gradually opens, the butterfly column 12322 moves to the outermost end of the locking mechanism guide groove 12314, the locking rotating block 1232 and the slider 13 stop moving outward, the lower end of the buckle plate 14 is fully opened, the lock tongue 221 is separated from the buckle plate 14, and the door can be closed normally.

[0024] The hidden screw type windproof floor suction of the present application does not adopt the common magnetic suction structure but adopts a mechanical structure to realize the function of floor suction. The buckle plate 14 on the windproof floor suction base can be converted between the closed and opened states, thereby solving the problem of failure to be attracted or being separated due to the action of magnetic force, windproof failure, etc. The hidden screw type windproof floor suction has good fixing effect and windproof effect. Meanwhile, the internal reset spring can buffer the impact force when the door body is pushed open and reduce the generation of noise. Moreover, the hidden screw type design is used to make the appearance more beautiful. The present application has simple structure, convenient processing and strong practicability.
