[0026] Please refer to Figures 1 to 3 , a lower lock plate guide assembly can be quickly assembled, including hexagonal head bolt 1, hexagonal head bolt 1 is provided with assembling mechanism 2 outside;Assembling mechanism 2 includes guide block bottom plate 201, guide block bottom plate 201 is sleeved on the outer wall of hexagonal head bolt 1 one side, the outer wall one side of guide block bottom plate 201 is equipped with first sliding groove 202, sliding block 204 is penetrated in the inside of first sliding groove 202, the end of sliding block 204 that penetrates first sliding groove 202 is fixedly installed with guide block side plate 203, the inner wall of guide block side plate 203 is equipped with second sliding groove 206, guide block panel 205 is penetrated in the inside of second sliding groove 206, the one side of guide block side plate 203 outer wall second sliding groove 206 is equipped with limiting groove 207, limiting block 209 is penetrated in the inside of limiting groove 207, wear plate 208 is fixedly installed at the end of limiting block 209 that penetrates limiting groove 207, rubber pad 210 is embedded in the inside of first sliding groove 202 and second sliding groove 206, guide block panel 205 constitutes sliding structure between second sliding groove 206 and guide block side plate 203, guide block side plate 203 constitutes sliding structure between first sliding groove 202 and guide block bottom plate 201.

[0027] By adopting the above technical scheme, the sliding block 204 slides along the first sliding groove 202, the limiting block 209 slides along the limiting groove 207, and cooperates with the second sliding groove 206, so that the guide block bottom plate 201, the guide block side plate 203, the guide block face plate 205 and the wear-resistant plate 208 are assembled with each other and are fixed by six groups of hexagonal head bolts 1 at the same time, so that the entire lower lock plate guide assembly can be quickly assembled, and the use of too many bolts for mutual fixation is avoided, which leads to relatively troublesome efficiency during installation. By bonding the rubber pad 210 inside the first sliding groove 202 and the second sliding groove 206, the sealing property can be improved, so that the anti-personnel door can maintain airtight effect and avoid leakage.

[0028] Specifically, as shown in Figure 1 , Figure 3 and Figure 4 , a guide groove 3 is arranged between the guide block bottom plate 201 and the guide block face plate 205, a sealing mechanism 4 is arranged inside the guide groove 3, the sealing mechanism 4 comprises a clamping groove 401, the clamping groove 401 is arranged inside the wear-resistant plate 208 on both sides, a contact plate 402 is slidably connected inside the clamping groove 401, a first air bag 403 is embedded at the bottom end of the contact plate 402, a ventilation pipe 404 is embedded on the inner wall of the wear-resistant plate 208, a second air bag 405 is fixedly installed at the top end of the ventilation pipe 404, a spring 406 is embedded above the contact plate 402 inside the clamping groove 401, the second air bag 405 communicates with the ventilation pipe 404, and the ventilation pipe 404 communicates with the first air bag 403.
