Description

Technical Field

[0001] This utility model relates to the field of hanging rail devices, and in particular to a hanging rail device with dustproof function for barn doors. Background Technology

[0002] Barn door sliding rails are a type of door that uses upper hanging wheels to support sliding. Unlike traditional sliding doors, they do not have a bottom track. Instead, they rely on upper hanging wheels for support and sliding. They are characterized by being noiseless, threshold-free, space-saving, and easy to install. They are suitable for installation in semi-enclosed spaces such as walk-in closets, studies, and storage rooms, which can both partition the space and enhance the overall aesthetics.

[0003] Because the barn door track is exposed, dust and impurities in the air can easily accumulate on the track after long-term use, causing the pulleys to jam during sliding and affecting the performance of the barn door. Installing a dust cover on the surface is not easy to remove and is inconvenient for maintenance. Therefore, we propose a hanging track device with dustproof function for barn doors. Utility Model Content

[0004] The main purpose of this utility model is to provide a hanging rail device with dustproof function for barn doors, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dustproof hanging rail device for barn doors includes a hanging rail body, a sliding structure that can slide on the hanging rail body, the sliding structure being in two sets, and a dustproof structure fixed above the hanging rail body.

[0007] Furthermore, the dustproof structure includes a dust cover, T-shaped blocks located behind the dust cover near both sides, and a first limiting groove located in front of the dust cover near the T-shaped blocks. There are two sets of the first limiting grooves, and each of the first limiting grooves is fitted with a limiting plate. It also includes a connecting rod that can slide inside the limiting plate, a spring on the surface of the connecting rod, a handle in front of the connecting rod, and a limiting block located behind the connecting rod. There are two sets of the limiting blocks.

[0008] Furthermore, the main body of the hanging rail includes two sets of mounting plates, a T-slot in front of the mounting plates for fixing the T-block, a first mounting hole in front of the mounting plates for mounting the mounting plates, a second limiting groove below the first mounting hole for limiting the limiting block, and a slide rail connecting the mounting plates, as well as a second mounting hole in front of the slide rail.

[0009] Furthermore, the sliding structure includes two sets of second U-shaped plates sleeved on the surface of the slide rail, two sets of pulleys located above the slide rail and rotatably connected between the second U-shaped plates, two sets of first U-shaped plates, four sets of fixing holes opened on the surface of the first U-shaped plates, embedding grooves opened on the adjacent surfaces of the first U-shaped plates and the second U-shaped plates, and embedding rotating shafts provided between the embedding grooves, wherein there are two sets of embedding rotating shafts.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0011] 1. The dust cover can protect the mounting plate, slide rail and pulley, thus preventing dust from entering the surface and affecting the performance of the hanging rail;

[0012] 2. Through the T-slot, T-block, second limiting slot, limiting block, spring, connecting rod, and handle, the T-block can be limited by the T-slot, and the dust cover is further limited by the limiting block embedded in the second limiting slot. Installation is convenient, and removal is only required by pulling the handle and lifting the dust cover upwards, thus realizing quick fixing and disassembly between the installation plate and the dust cover.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1-6 A dustproof hanging rail device for barn doors includes a hanging rail body 2, a sliding structure 3 that can slide on the hanging rail body 2, the sliding structure 3 being two sets, and a dustproof structure 1 fixed above the hanging rail body 2.

[0022] Specifically, the main body 2 of the hanging rail serves to connect the wall and the barn door panel, and is used to fix it to the wall or door frame. The sliding structure 3 is connected to the barn door and can drive the barn door to slide under the main body 2 of the hanging rail.

[0023] In a preferred embodiment, the dustproof structure 1 includes a dust cover 101, T-shaped blocks 102 located behind the dust cover 101 near both sides, and a first limiting groove 103 located in front of the dust cover 101 near the T-shaped blocks 102. There are two sets of first limiting grooves 103, each with a limiting plate 105 embedded inside. The structure also includes a connecting rod 106 that can slide inside the limiting plate 105, a spring 107 on the surface of the connecting rod 106, a handle 104 in front of the connecting rod 106, and two limiting blocks 108 located behind the connecting rod 106. The dust cover 101 is L-shaped and can shield and protect the top and front of the hanging rail body 2. One end of the spring 107 is fixed to one side of the limiting plate 105, and the other end is fixed to one side of the limiting block 108. The limiting block 108 is a triangular block. When the dust cover 101 is fixed from top to bottom in front of the mounting plate 201, the limiting block 108 is squeezed. When the limiting block 108 reaches the second limiting groove 206, the spring 107 returns to its original position, so that the limiting block 108 is embedded in the interior of the second limiting groove 206 for fixation. The T-shaped block 102 serves to connect the dust cover 101 and the mounting plate 201. The limiting plate 105 is located inside the first limiting groove 103 near the front, which can block and restrict the position of the spring 107 to prevent the spring 107 from detaching from the first limiting groove 103.

[0024] Specifically, by pulling the handle 104 to one side and forward, the spring 107 can be compressed, thereby causing the connecting rod 106 to move inside the first limiting groove 103, which in turn drives the limiting block 108 to move, thus facilitating the removal of the dust cover 101.

[0025] In a preferred embodiment, the main body 2 of the hanging rail includes two sets of mounting plates 201, a T-slot 203 in front of the mounting plates 201 for fixing the T-block 102, a first mounting hole 202 in front of the mounting plates 201 for mounting the mounting plates 201, a second limiting groove 206 below the first mounting hole 202 for limiting the limiting block 108, and a slide rail 205 connected between the mounting plates 201, and a second mounting hole 204 in front of the slide rail 205. The first mounting hole 202 and the second mounting hole 204 are both fixed to the wall or door frame by bolts for mounting the mounting plates 201.

[0026] Specifically, the mounting plate 201 and the slide rail 205 are installed and fixed by inserting bolts into the second mounting hole 204 and the first mounting hole 202 and tightening them to the wall or door frame.

[0027] In a preferred embodiment, the sliding structure 3 includes two sets of second U-shaped plates 304 sleeved on the surface of the slide rail 205, two sets of pulleys 301 located above the slide rail 205 and rotatably connected between the second U-shaped plates 304, two sets of first U-shaped plates 303, four sets of fixing holes 302 formed on the surface of the first U-shaped plates 303, embedding grooves 305 formed on the adjacent surfaces of the first U-shaped plates 303 and the second U-shaped plates 304, and embedding rotating shafts 306 provided between the embedding grooves 305. There are two sets of embedding rotating shafts 306. Wear-resistant pads are provided between the second U-shaped plates 304 and the first U-shaped plates 303, which helps to reduce the severe wear caused by direct friction between the second U-shaped plates 304 and the first U-shaped plates 303, and helps to improve their service life. The pulleys 301 can slide above the slide rail 205. The first U-shaped plates 303 and the second U-shaped plates 304 can rotate under the action of the rotating shafts 306, but the two will not separate.

[0028] Specifically, the first U-shaped plate 303 is fixed to the barn door using fixing holes 302 and bolts. When the barn door opens and closes, the pulley 301 slides on the slide rail 205. When the barn door rotates, the second U-shaped plate 304 and the first U-shaped plate 303 rotate under the action of the rotating shaft 306, thus not affecting the normal rotation of the barn door.

[0029] It should be noted that during installation, the T-block 102 is inserted into the T-slot 203 from top to bottom, and is limited by the limiting block 108 and the second limiting slot 206. When disassembling, pull the handle 104 forward to compress the spring 107, and the limiting block 108 moves away from the second limiting slot 206. At this time, lift the dust cover 101 upward to move the T-block 102 away from the T-slot 203 to complete the disassembly.

[0030] The first U-shaped plate 303 is fixed to the door with bolts. When the door is opened and closed, the pulley 301 slides above the slide rail 205, and the angle between the second U-shaped plate 304 and the first U-shaped plate 303 changes.

[0031] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
