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

[0003] A floor lock is a device that holds a door in place after it's opened, preventing it from being blown or slammed shut by wind. Currently, floor locks on the market are typically secured with magnets, which produce a clattering sound when attached and require a firm pull to separate. In strong winds, the magnets can become loose, causing the door to crash. Furthermore, over time, the magnet's magnetic properties weaken, gradually degrading the lock's functionality. Consequently, a number of windproof floor locks with mechanical locks have emerged on the market. Furthermore, the mounting screws are often exposed, which degrades the aesthetics. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above shortcomings and provide a hidden screw type windproof floor suction, which can solve the problem that the magnetic floor suction cannot be attracted or is not attracted tightly and cannot prevent wind, and has the advantages of low noise and hidden installation screws.

A boss 155 is provided on the side of the slider pressure plate 15. The base step columns 125 on both sides of the base 12 are respectively embedded in the connecting holes 151 of the two slider pressure plates 15, and the pressure plate fixing columns 126 are respectively embedded in the pressure plate fixing holes 153; two screws 128 are respectively passed through the pressure plate screw holes 152 of the two slider pressure plates 15 and the base screw holes 127 on both sides of the base 12 to connect and fix the two pressure plates 15 and the base 12; the boss 155 is pressed against the slider pressure plate groove 133, and the base cover 11 is fixed to the base 12 by the base cover buckle 112 and the pressure plate buckle. The top of the gusset plate 14 is provided with a spring hook 141, the upper part is provided with a gusset plate hole 142, and the side of the gusset plate 14 is provided with a gusset plate guide rail 143. The gusset plate guide rails 143 of the two gusset plates 14 are respectively abutted against the two sides of the base trumpet 121, and the slider column 135 is respectively embedded in the gusset plate holes 142 of the two gusset plates 14, and a gusset plate return spring 144 is provided, the two ends of which are respectively inserted into the spring hooks 141 of the two gusset plates 14.The locking rotating block 1232 is provided with a locking rotating shaft 12321 at its upper portion and a butterfly column 12322 at its lower portion. 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 engaged with 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 retaining groove 211 and a lock tongue limiting spring 212, and the lock tongue limiting spring 212 is embedded in the lock tongue retaining groove 211. The lock tongue seat 22 is provided with a lock tongue 221 at its bottom and an embedding groove 222 on its side, and the lock tongue fixing seat 21 is embedded in the embedding groove 222.

[0021] When the door is opened, the lock tongue 221 on the latch assembly 2 pushes the slider block 132 of the slider 13 through the base trumpet 121 due to the rotation of the door body, causing the slider 13 to slide. 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 inward in the locking mechanism guide groove 12314. At the same time, the latch plate 14 rotates under the action of the slider 13 and the base slide rail 122, and the lower end of the latch plate 14 gradually closes until the latch plate 14 locks the lock tongue 221. When the butterfly column 12322 moves to the positioning point a12311, the locking rotating block 1232 stops moving inward under the action of the positioning point a12311, and the butterfly column 12322 rotates When the locking block 1232 is stopped, the locking latch 221 is locked 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 and drives 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, 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 present invention's hidden screw-type windproof floor suction uses a mechanical structure instead of the commonly used magnetic suction structure to achieve the floor suction function. The gusset plate 14 on the windproof floor suction base can switch between closed and open states, thus solving the problem of magnetic failure to attract or detachment in strong winds, resulting in windproof failure. It has excellent fixing and windproof effects. At the same time, the internal reset spring can buffer the impact force when the door is pushed open, reducing the generation of noise. The use of a hidden screw design also makes the appearance more beautiful. The present invention has a simple structure, is easy to process, and is highly practical.
