Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0023] A maglev sliding door rail structure member includes a load-bearing rail 2, and a square steel bar 3 is arranged on the top of the load-bearing rail 2; a U-shaped steel member 1 is also arranged in the load-bearing rail 2, a magnetic steel 4 is arranged on the top surface of the U-shaped steel member 1, and the magnetic steel 4 attracts the square steel bar 3; a load-bearing screw 6 is arranged on the bottom surface of the U-shaped steel member 1, and the load-bearing screw 6 is threadedly connected to the sliding door; a positioning wheel 5 is rotatably connected above the magnetic steel 4, and the positioning wheel 5 abuts against the side surface of the square steel bar 3.
[0024] Specifically, please refer to Figures 1-3 , the load-bearing screw 6 is arranged at the center of the bottom surface of the U-shaped steel member 1, the square steel bar 3 is arranged at the center of the inner top surface of the load-bearing rail 2, there are two magnetic steels 4 symmetrically arranged on both sides of the top surface of the U-shaped steel member 1, limiting columns are symmetrically arranged on both sides of the top surface of the U-shaped steel member 1, and the limiting columns are threadedly connected to the U-shaped steel member 1. Limiting holes are opened at the center of the top surfaces of the magnetic steel 4 and the positioning wheel 5, a gasket is arranged between the magnetic steel 4 and the positioning wheel 5, there are four positioning wheels 5, and two positioning wheels 5 are in a group and are symmetrically arranged on the top surfaces of the two magnetic steels 4.
[0025] By adopting the above design, when the sliding door needs to be opened or closed, the sliding door can be driven to move along the load-bearing rail 2 by an external power source (such as a motor or manually). Due to the attraction between the magnetic steel 4 and the square steel bar 3, the sliding door maintains a stable levitation state during the movement, reducing friction and noise. The positioning wheel 5 rolls on the side surface of the square steel bar 3, providing additional stability and guiding effect for the sliding door.
[0026] The maglev design makes the sliding door produce almost no friction during the movement, significantly reducing the noise and improving the use experience.
[0027] Due to the reduction of friction and wear, the service life of the sliding door and the rail structure member is significantly extended.
[0028] The attraction between the magnetic steel 4 and the square steel bar 3 and the guiding effect of the positioning wheel 5 together ensure the stability of the sliding door during the movement, reducing shaking and deviation.
[0029] The above advantages enable the maglev sliding door rail structure to be widely used in occasions such as high-class office buildings, hospitals, airports, etc. that require high stability and low noise.
[0030] Please refer to Figures 1-4 , further, guiding grooves 7 are symmetrically formed at the lower ends on both sides of the U-shaped steel member 1. A limiting and guiding block 9 is slidably connected in the guiding groove 7. A scraping rod 11 is fixedly connected to the limiting and guiding block 9. The scraping rod 11 is L-shaped and adapted to the inner wall of the load-bearing rail 2. A limiting convex 10 is arranged at a position near the side wall of the U-shaped steel member 1 in the guiding groove 7. There are two limiting convexes 10 arranged symmetrically. One end of a spring 8 is fixedly connected in the guiding groove 7, and the other end of the spring 8 is fixedly connected to the limiting and guiding block 9.
[0031] By adopting the above design, during the reciprocating movement of the sliding door, the scraping rod 11 slides in the guiding groove 7 through the limiting and guiding block 9, automatically cleaning the dust and sundries on the inner wall of the load-bearing rail 2 as the sliding door moves. The spring 8 provides elastic force for the limiting and guiding block 9 to ensure that the scraping rod 11 keeps close contact with the inner wall of the load-bearing rail 2, improving the cleaning effect.
[0032] The scraping rod 11 automatically cleans the inner wall of the load-bearing rail 2 as the sliding door moves, reducing the need for manual cleaning and improving the maintenance efficiency of the equipment.
[0033] Working principle:
[0034] During installation, first, the load-bearing rail 2 is fixed at the required position. The square steel bar 3 is installed at the central position on the top of the load-bearing rail 2. The U-shaped steel member 1 and the sliding door are fixedly connected by a threaded connection through the load-bearing screw 6. The positioning wheel 5 is installed above the magnetic steel 4 through a gasket and ensured to be able to rotate freely while abutting against the side surface of the square steel bar 3. The U-shaped steel member 1 is placed in the load-bearing rail 2 to ensure that the magnetic steel 4 and the square steel bar 3 maintain an appropriate distance for mutual attraction.
[0035] When the sliding door needs to be opened or closed, the sliding door can be driven to move along the load-bearing rail 2 by an external power source (such as a motor or manually). Due to the attraction between the magnetic steel 4 and the square steel bar 3, the sliding door maintains a stable suspended state during the movement, reducing friction and noise. The positioning wheel 5 rolls on the side surface of the square steel bar 3, providing additional stability and guiding effect for the sliding door.
[0036] During the reciprocating movement of the sliding door, the scraping rod 11 slides in the guiding groove 7 through the limiting and guiding block 9, automatically cleaning the dust and sundries on the inner wall of the load-bearing rail 2 as the sliding door moves. The spring 8 provides elastic force for the limiting and guiding block 9 to ensure that the scraping rod 11 keeps close contact with the inner wall of the load-bearing rail 2, improving the cleaning effect.
