[0023] To make the purpose, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the drawings.

[0024] The present invention provides a sliding push-pull door. By arranging a one-way rack on the side wall of the door frame, a one-way gear is rotatably connected to the side wall of the fixed plate at the bottom of the door leaf. Rotating rods are rotatably connected to both ends of the fixed plate. The rotating rods are connected to the one-way gear. The one-way gear meshes with the one-way rack. Brushes are arranged at both ends of the rotating rods. During the upward pulling process of the fixed plate and the door leaf, the one-way rack drives the one-way gear to rotate, and then drives the rotating rods and the bristles to rotate. During the upward movement of the door leaf, the bristles clean the inside of the roller groove to prevent dust, debris, etc. from remaining in the roller groove and damaging the rolling path.

[0025] Figures 1-3 Shown is a schematic structural diagram of an embodiment of a sliding push-pull door of the present invention. Please refer to Figures 1-3 , A sliding push-pull door of this embodiment includes a door frame 100, a fixed plate 200, and a dust suction assembly 300.

[0026] The door frames 100 are two and symmetrically arranged. A sliding groove 110 is formed in the side wall of the door frame 100, a roller groove 120 is formed in the inner wall of the sliding groove 110, and a one-way rack 130 is installed on the side wall of the door frame 100.

[0027] A door leaf 210 is installed on the top of the fixing plate 200. Both ends of the fixing plate 200 are respectively located inside the two sliding grooves 110. Rotating rollers 220 are connected to both ends of the fixing plate 200. The rollers 220 are located inside the roller groove 120. A one-way gear 230 is rotatably connected to the side wall of the fixing plate 200. The one-way gear 230 meshes with the one-way rack 130. A first pulley 231 is installed on the side wall of the one-way gear 230. A second pulley 240 is rotatably connected to the top of the fixing plate 200. A third pulley 241 is installed on the side wall of the second pulley 240. The second pulley 240 and the first pulley 231 are connected by a belt. Rotating rods 250 are rotatably connected to the tops of both ends of the fixing plate 200. Brushes 251 are installed at both ends of the rotating rods 250. A 252 is installed on the rod body of the rotating rod 250. The 252 and the third pulley 241 are connected by a belt. A first helical gear 242 is installed on the side wall of the third pulley 241. A reciprocating threaded rod 260 is rotatably connected to the top of the fixing plate 200. A second helical gear 261 is installed at the side end of the reciprocating threaded rod 260. The second helical gear 261 meshes with the first helical gear 242. A pull rod 270 is installed on the side wall of the fixing plate 200. An anti-slip sleeve 271 is installed on the rod body of the pull rod 270. A protective sleeve 280 is wrapped around the side wall of the fixing plate 200. When the head collides with the fixing plate 200, the protective sleeve 280 can protect the head and reduce the damage suffered by the head. The anti-slip sleeve 271 can increase the friction between the hand and the pull rod 270. When the fixing plate 200 is pushed to drive the door leaf 210 to move upward, the one-way rack 130 drives the one-way gear 230 and the first pulley 231 to rotate. The first pulley 231 drives the second pulley 240 and the third pulley 241 to rotate by means of a belt. The third pulley 241 drives the 252 and the rotating rod 250 to rotate by means of a belt, and then drives the brush 251 to rotate. When the brush 251 rotates, it cleans the inside of the roller groove 120, sweeps out the dust, stains, etc. inside the roller groove 120, and prevents damage to the roller 220.

[0028] The dust collection assembly 300 includes a housing 310 installed at the top of the door frame 100 and a piston 320 located inside the housing 310. A fixed rod 321 is installed on the side wall of the piston 320, and a reciprocating threaded hole 322 is formed at the side end of the fixed rod 321. The reciprocating threaded rod 260 rotates and extends into the reciprocating threaded hole 322. A first pipe body 330 is installed on the side wall of the housing 310, and a first one-way valve 331 is installed on the body of the first pipe body 330. A second pipe body 340 is installed on the top of the housing 310, and a second one-way valve 341 is installed on the body of the second pipe body 340. A pull rod 270 is installed on the side wall of the fixed plate 200. When the third pulley 241 rotates, it drives the first bevel gear 242 to rotate. The first bevel gear 242 drives the second bevel gear 261 and the reciprocating threaded rod 260 to rotate. The reciprocating threaded rod 260 uses a screw structure to push the fixed rod 321 to drive the piston 320 to reciprocate inside the housing 310. When the piston 320 moves towards the outside of the housing 310, at this time the second one-way valve 341 opens and the first one-way valve 331 closes. The negative pressure inside the housing 310 generates suction at the other end of the second pipe body 340, sucking the dust swept out by the brush 251 into the housing 310. When the piston 320 moves towards the inside of the housing 310, the second one-way valve 341 closes and the first one-way valve 331 opens. The air and dust inside the housing 310 are discharged from the first pipe body 330.

[0029] Although the present utility model has been described above with reference to the embodiments, however, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way.
