Description

[0001] The present invention is a divisional application of a Chinese patent application filed with the China Patent Office on October 11, 2019, with application number 201910963982.7 and titled “Hidden Screw Type Windproof Floor Suction”. Technical Field

[0002] The invention relates to the field of common floor suction structures for building door and window hardware, and in particular to a windproof floor suction structure using hidden screws. Background Art

[0003] The floor suction is a positioning device that sucks the door after the door leaf is opened to prevent the door leaf from closing due to wind or touching it. The floor suction on the market is generally fixed by magnets. It will make a collision sound when it is sucked, and it needs to be pulled apart with force. When encountering strong winds, the magnets will be detached due to insufficient suction force, causing the door to collide. In addition, the magnetism of the magnet will decay over time, and the function of the floor suction will gradually be lost. As a result, a number of mechanical lock-type windproof floor suctions have emerged on the market. In addition, the commonly used floor suction installation screws are exposed, which has a certain impact on the appearance. Summary of the invention

The butterfly column 12322 is provided with butterfly column V-shaped grooves 12323 at both ends, and locking rotating block guide rails 12324 are provided on both sides of the butterfly column 12322; the locking rotating shaft 12321 is embedded in the slider hole 131, and the butterfly column 12322 is clamped in the locking groove 1231. The lock tongue assembly 2 includes a lock tongue fixing seat 21 and a lock tongue seat 22. The lock tongue fixing seat 21 is provided with a lock tongue clamping groove 211 and a lock tongue limiting spring 212, and the lock tongue limiting spring 212 is embedded in the lock tongue clamping groove 211; the lock tongue seat 22 is provided with a lock tongue 221 at the bottom, and an embedded groove 222 is provided on the side, and the lock tongue fixing seat 21 is embedded in the embedded groove 222.

[0021] Under normal circumstances, the buckle plate 14 on the base 12 of the hidden screw type windproof floor suction of the present invention is in an open state. When the door is opened, the lock tongue 221 on the lock tongue assembly 2 pushes the slider push block 132 of the slider 13 through the base trumpet mouth 121 due to the rotation of the door body, causing the slider 13 to slide, and the slider 13 drives the locking rotating block 1232 matched therewith to move, and the locking rotating block 1232 drives the butterfly column 12322 to move inwardly in the locking mechanism guide groove 12314. At the same time, the buckle plate 14 rotates under the action of the slider 13 and the base slide rail 122, and the lower end of the buckle plate 14 gradually closes until the buckle plate 14 locks the lock tongue 221. When the butterfly column 12322 moves to the positioning point a12311, under the action of the positioning point a12311, the locking rotating block 1232 stops moving inwardly, and the butterfly column 12322 rotates The locking block 1232 stops moving outwards, and the other end of the butterfly column 12322 rotates to the stop position c12313. Because the lateral distance of the butterfly column 12322 after rotation is larger than the width of the locking mechanism guide groove 12314, the butterfly column 12322 is fixed on the locking mechanism guide groove 12314, limiting the rotation of the locking rotation block 1232. The slider 13 stops moving to lock the lock tongue 221, and the door body is fixed on the base 12.

[0022] When closing the door, it is only necessary to push the door body again, and the door body drives the lock tongue 221 to push the slider push block 132, and the slider 13 drives the locking rotating block 1232 to move inward together. When the butterfly column 12322 moves to the positioning point a12311, under the action of the positioning point a12311, the locking rotating block 1232 stops moving inward, and the butterfly column 12322 rotates to the horizontal direction. Under the action of the slider return spring 137, the slider 13 moves outward to drive the locking rotating block 1232 to move outward. 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, and 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.

[0023] The hidden screw type windproof floor suction of the present invention does not adopt the commonly used magnetic suction structure but adopts a mechanical structure to realize the function of the floor suction. The buckle plate 14 on the windproof floor suction base can switch between closed and open states, thereby solving the problem of failure to attract or detachment due to strong wind and windproof failure caused by the action of magnetic force, and has a good fixing effect and windproof effect; at the same time, because a reset spring is arranged inside, it can buffer the impact force when the door body is pushed open and reduce the generation of noise; and the use of a hidden screw design makes the appearance more beautiful. The present invention has a simple structure, convenient processing, and strong practicality.
