[0025] Reference Figures 1 to 8A sliding door guide rail that can be automatically closed includes a track 1, a slide groove 11 arranged on the track 1, and a caster 2 slidably arranged in the slide groove 11, the left and right sides of the slide groove 11 are provided with grooves 12, and the groove 12 is provided with a plurality of baffles 3 that can move in the left and right directions and can extend out of the groove 12, and the baffles 3 matching on the left and right sides are engaged with each other to cover and block the slide groove 11, and the groove 12 is provided with a reset mechanism 4 that can drive the baffle 3 to move to the outside of the groove 12, and a push plate 21 is provided on the caster 2 and located at the baffle 3, and a driving mechanism 5 that can move the baffles 3 on both sides to the inside of the groove 12 is provided between the baffle 3 and the push plate 21. In this way, the baffles 3 on the left and right sides will be closed to cover and block the chute 11 on the track 1, so as to hide the chute 11 and prevent it from being exposed to the outside, thereby preventing dust and debris from entering the chute 11, facilitating the sliding of the caster 2 in the chute 11, and improving its service life. At the same time, it can also reduce the trouble of cleaning the chute 11. When the caster 2 slides along the chute 11, the push plate 21 thereon moves the baffles 3 on both sides toward the inside of the groove 12 through the driving mechanism 5, so that it can slide in the chute 11, and after the caster 2 slides, the baffles 3 on the left and right sides are moved toward the outside of the groove 12 through the reset mechanism 4, so that the baffles 3 on the left and right sides are re-engaged with each other to cover and block the chute 11.

[0026] In the present embodiment, the reset mechanism 4 includes a reset spring 41 which is arranged in the groove 12 and abuts against the inner side of the baffle 3. Specifically, a docking joint for assembling the reset spring 41 is provided on the inner side of each baffle 3 and the inner wall of the groove 12, so that the baffle 3 is pushed to move toward the outside of the groove 12 by the reset spring 41, so that the baffles 3 on both sides are engaged with each other to cover and block the slide groove 11.

[0027] In this solution, a first strip plate 13 is provided on both sides of the left and right sides of the slide groove 11, and a second strip plate 14 is provided below the first strip plate 13. The height of the upper surface of the first strip plate 13 is the same as the height of the upper surface of the track 1. The first strip plate 13 and the second strip plate 14 are combined to form the groove 12. In this way, the slide groove 11 is covered and shielded by the cooperation of the first strip plate 13 and the baffle 3 in the groove 12.

[0028] In the present embodiment, a guide pair 31 is provided between the two adjacent front and rear baffles 3 for guiding the baffle 3 to move in the left and right direction. The guide pair 31 includes a guide groove 311 provided on one side of the front end or rear end of the baffle 3, and a guide rail 312 provided on the adjacent baffle 3 and matched with the guide groove 311, so that the baffle 3 can move in the left and right direction in the groove 12 without deviation through the guide pair 31.

[0029] In this embodiment, the baffle plate 3 includes a first baffle plate 32 located on the left side of the groove 12, and a second baffle plate 33 located on the right side of the groove 12. A V-shaped groove 321 is provided on the outer side of the first baffle plate 32, and a plug 331 matching the V-shaped groove 321 is provided on the outer side of the second baffle plate 33, so that the V-shaped groove 321 and the plug can be connected to each other, which is beneficial to the connection between the first baffle plate 32 and the second baffle plate 33 on the left and right sides.

[0030] In one embodiment of the present scheme, the driving mechanism 5 includes a mechanism that can enable the push plate 21 to push the baffles 3 on both sides to move toward the inner side of the groove 12 by direct contact. The driving mechanism 5 can be provided with mutually matching push-up inclined surfaces between the push plate 21 and the baffles 3 on both sides, or can be provided with mutually matching pulleys between the push plate 21 and the baffles 3 on both sides, wherein the pulley on the push plate 21 is located in the middle, and the pulleys on the left and right baffles 3 are located on both sides, so that the push plate 21 can knock open the baffles 3 on both sides. Specifically, the driving mechanism 5 includes a pushing structure 51 arranged between the push plate 21 and the baffle 3, and the pushing structure 51 includes a first pushing inclined surface 511 arranged on the rear side of the bottom of the baffle 3, and a second pushing inclined surface 512 arranged at the front end of the push plate 21 and matched with the first pushing inclined surfaces 511 on the left and right sides. Preferably, the first pushing inclined surfaces 511 on the left and right baffles 3 cooperate to form a V-shaped pushing inclined surface, and the shape of the second pushing inclined surface 512 is also V-shaped, so that when the push plate 21 passes by, the first pushing inclined surface 511 is pushed by the second pushing inclined surface 512, so that the baffles 3 on both sides move into the groove 12 to avoid blocking the caster 2 from moving in the slide groove 11. Furthermore, a third pushing inclined surface 513 is provided on the front bottom side of the baffle 3, and a fourth pushing inclined surface 514 is provided at the rear end of the push plate 21 to cooperate with the third pushing inclined surfaces 513 on the left and right sides. Specifically, the third pushing inclined surfaces 513 on the baffles 3 on the left and right sides cooperate to form a V-shaped pushing inclined surface, and the shape of the fourth pushing inclined surface 514 is also V-shaped, so that after the caster 2 slides over, the baffles 3 on both sides will not close quickly under the action of the reset mechanism 4, but have a certain buffer, thereby reducing noise and preventing the baffles 3 on the left and right sides from being damaged by a large impact.

[0031] In this embodiment, a roller 515 is provided at the bottom of the baffle 3 and between the first push-up slope 511 and the third push-up slope 513. Specifically, the first push-up slope 511 and the third push-up slope cooperate to form a V-shaped surface at the bottom of the baffle 3, and the roller 515 is arranged at the apex of the V-shaped surface, so that the baffles 3 on the left and right sides can be pushed open by using the push plate 21.

[0032] In this embodiment, the driving mechanism 5 includes a mechanism that can enable the push plate 21 to push the baffles 3 on both sides to move toward the inner side of the groove 12 in a non-contact manner. The driving mechanism 5 can be provided with mutually cooperating permanent magnets between the push plate 21 and the baffles 3 on both sides, so that the push plate 21 can push the baffles 3 on both sides open. Specifically, the driving mechanism 5 includes a magnetic push structure 52 arranged between the push plate 21 and the baffle 3, and the magnetic push structure 52 includes a first magnet 521 arranged at the bottom of the first baffle 32, a second magnet 522 arranged at the bottom of the second baffle 33 and magnetically attracted to the first magnet 521, a third magnet 523 arranged at the left side of the front end of the push plate 21 and magnetically repelled by the first magnet 521, and a fourth magnet 524 arranged at the right side of the front end of the push plate 21 and magnetically repelled by the second magnet 522. In this way, when the push plate 21 passes by, the first magnet 521 repels the third magnet 523, and the second magnet 522 repels the fourth magnet 524, thereby causing the baffles 3 on both sides to move into the groove 12. Preferably, a fifth magnet 525 that magnetically repels the third magnet 523 is provided on the left side of the rear end of the push plate 21, and a sixth magnet 526 that magnetically repels the fourth magnet 524 is provided on the right side of the rear end of the push plate 21, so that after the caster 2 slides over, the baffles 3 on both sides will not close quickly under the action of the reset mechanism 4, but have a certain buffer, thereby reducing noise and preventing the baffles 3 on the left and right sides from being damaged by a large impact.
