Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, and more specifically, to a suspension device for a sliding door. Background Technology

[0002] Sliding doors are a common type of door. Top-mounted sliding doors use a suspension device to suspend the door from the ground, eliminating the need for a track and keeping the floor clean and tidy. However, most suspension devices typically include a track and rollers. When the spacing between the rollers on both sides is different from the track size, the rollers usually need to be replaced, which is troublesome to install and replace, limiting their applicability. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a sliding door suspension device, which has the advantages of simple installation and replacement operation and wide applicability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sliding door suspension device, including a track, a movable body slidably connected inside the track, a stud engaged at the left end of the movable body, a connecting shaft slidably connected to the middle and right side of the movable body, a synchronous plate movably connected to the surfaces of the stud and the connecting shaft, a roller rotatably connected to the side of the stud and the connecting shaft away from the movable body, and a cross groove opened on the side of the stud away from the movable body.

[0005] As a preferred embodiment of this utility model, both the left and right ends of the movable body are engaged with adjusting screws, and the bottom end of the adjusting screws is rotatably connected to a mounting bracket.

[0006] As a preferred embodiment of this utility model, a limiting ring is fixedly installed on the surface of the stud and the connecting shaft, and the limiting ring positions the synchronizing plate and the roller.

[0007] As a preferred embodiment of this utility model, extension frames are fixedly installed on both the front and rear sides of the movable body. A fixed shaft is fixedly installed on the side of the extension frame closer to the movable body. A scraper is slidably connected to the surface of the fixed shaft. A spring is fixedly installed between the scraper and the extension frame.

[0008] As a preferred embodiment of this utility model, the cross-sectional shape of the fixed shaft is "T" shaped, and the spring is sleeved on the fixed shaft.

[0009] As a preferred embodiment of this utility model, magnets are fixedly installed at both ends of the track, and slag discharge ports are opened on both the left and right sides of the bottom end of the track.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a Phillips screwdriver inserted into a Phillips head slot to rotate the stud. The engagement between the stud and the moving body drives the stud to move relative to the moving body, causing the stud to extend or retract. This, in turn, drives the connecting shaft to extend or retract through a synchronous plate, thereby changing the distance between the roller and the moving body. This allows the moving body to be used with various track sizes, facilitating installation or replacement and broadening its application range.

[0012] 2. By setting a scraper, when the moving body drives the roller to move in the track, the scraper contacts the bottom end of the track and scrapes off the dust on the bottom end of the track, thereby avoiding the accumulation of dust and other debris over a long period of time, which would cause the roller to move unevenly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5As shown, this utility model provides a sliding door suspension device, including a track 1, a movable body 2 slidably connected inside the track 1, a stud 5 engaged at the left end of the movable body 2, a connecting shaft 6 slidably connected to the middle and right side of the movable body 2, a synchronous plate 7 movably connected to the surface of the stud 5 and the connecting shaft 6, and a roller 8 rotatably connected to the side of the stud 5 and the connecting shaft 6 away from the movable body 2, and a cross groove 9 is opened on the side of the stud 5 away from the movable body 2.

[0021] By inserting a Phillips screwdriver into the Phillips head slot 9 and rotating the stud 5, the stud 5 is driven to move relative to the moving body 2 through the engagement of the stud 5 with the moving body 2, causing the stud 5 to extend or retract from the moving body 2. This, in turn, drives the connecting shaft 6 to extend or retract from the moving body 2 through the synchronization plate 7, thereby changing the distance between the roller 8 and the moving body 2. This allows the moving body 2 to be used with various sizes of tracks 1, making it easier to install or replace the moving body 2 and expanding its application range.

[0022] The moving body 2 has adjusting screws 3 engaged at both its left and right ends, and the bottom end of the adjusting screws 3 is rotatably connected to the mounting bracket 4.

[0023] The mounting bracket 4 is fixedly connected to the sliding door body. The length of the adjusting screw 3 extending from the top of the moving body 2 is changed by rotating the adjusting screw 3, thereby changing the height of the sliding door body.

[0024] Among them, the surface of the stud 5 and the connecting shaft 6 is fixedly installed with a limit ring, which positions the timing plate 7 and the roller 8.

[0025] By setting a limit ring, the corresponding roller 8 can be moved when the stud 5 and the connecting shaft 6 move. At the same time, when the stud 5 moves, the synchronous plate 7 can be moved, and the movement of the synchronous plate 7 can drive the movement of the connecting shaft 6.

[0026] Among them, extension frames 10 are fixedly installed on both the front and rear sides of the mobile body 2. A fixed shaft 11 is fixedly installed on the side of the extension frame 10 closest to the mobile body 2. A scraper 12 is slidably connected to the surface of the fixed shaft 11. A spring 13 is fixedly installed between the scraper 12 and the extension frame 10.

[0027] By setting a scraper 12, when the moving body 2 drives the roller 8 to move in the track 1, the scraper 12 contacts the bottom end of the track 1 to scrape off the dust on the bottom end of the track 1, thereby avoiding the accumulation of dust and other debris over a long period of time, which would cause the roller 8 to move unsmoothly.

[0028] The fixed shaft 11 has a "T" shaped cross section, and the spring 13 is sleeved on the fixed shaft 11.

[0029] By setting the fixed shaft 11 to a "T" shape, the protrusion at the rear end of the fixed shaft 11 can be used to limit the scraper 12, preventing the scraper 12 from falling off, and to position the contraction of the spring 13, so that the spring 13 is locked between the track 1 and the moving body 2.

[0030] Magnets 14 are fixedly installed at both ends of the track 1, and slag discharge ports 15 are opened on both the left and right sides of the bottom end of the track 1.

[0031] When the moving body 2 moves to a position close to the magnet 14, the magnet 14 attracts the scraper 12, causing the scraper 12 to move toward the magnet 14 and compress the spring 13. At this time, the dust scraped off by the scraper 12 will fall through the slag discharge port 15.

[0032] Working principle and usage process of this utility model:

[0033] When in use, first insert a Phillips screwdriver into the Phillips groove 9 and rotate the stud 5. The engagement between the stud 5 and the moving body 2 causes the stud 5 to extend or retract into the moving body 2, thereby changing the position of the roller 8 on the stud 5. When the stud 5 moves, the stud 5 drives the connecting shaft 6 on the same side to move together through the synchronous plate 7, thereby changing the distance between the rollers 8 on the front and rear sides, so that the rollers 8 can be placed at the bottom of the track 1 of different specifications.

[0034] Then, the movable body 2 is inserted into the track 1, and the mounting bracket 4 is used to fix it to the door body. The height of the door body is adjusted by adjusting the screw 3.

[0035] When the door moves, the door will drive the moving body 2 to move, which in turn will drive the scraper 12 and roller 8 to move at the bottom of the track 1. The movement of the scraper 12 will scrape away dust and other impurities at the bottom of the track 1. Since the top and middle of the scraper 12 are made of iron and the bottom is made of rubber, the contact between the scraper 12 and the track 1 will not produce too much noise.

[0036] When the door moves to a fully closed or open position, the moving body 2 moves to its limit position. At this time, there is still a certain distance between the moving body 2 and the end of the track 1. At this time, the magnetism of the magnet 14 will generate a magnetic force with the iron part of the scraper 12, pulling the scraper 12 to the slag discharge port 15 again. At this time, the dust and impurities scraped by the scraper 12 fall to the ground through the slag discharge port 15.
