Description

Technical Field

[0001] This utility model relates to the technical field of sliding door load-bearing guide rail structure, specifically an adjustable sliding door load-bearing guide rail structure. Background Technology

[0002] Sliding doors are widely used in homes, commercial spaces, and industrial settings. They open by sliding along a track, eliminating the need for outward or inward swing space like hinged doors, thus saving space. The track structure is the core component of a sliding door, and almost all sliding doors rely on it for operation.

[0003] Current sliding door support rail structures often cannot flexibly adjust the support height between the sliding body and the bottom of the door to meet the different installation height and level calibration requirements of the bottom of the door. Furthermore, the nylon wheels at the bottom of the sliding body generate significant frictional resistance and losses with the inner wall of the track as the door moves, affecting the service life. Based on this, we propose a new type of adjustable sliding door support rail structure. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable sliding door support rail structure to solve the problems mentioned in the background art, such as the difficulty in independently adjusting the support height and the large frictional resistance loss.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable sliding door support rail structure, including a slide rail base, a limiting groove is provided inside the slide rail base, a sliding body is uniformly slidably connected inside the limiting groove, nylon wheels are uniformly movably connected to both sides of the sliding body, a strip-shaped perforated plate is uniformly fixed to the inner side wall of the limiting groove, and ball bearings in contact with the nylon wheels are uniformly movably connected to the strip-shaped perforated plate, a reserved lubrication cavity is provided on both sides of the slide rail base, a lubricant is installed inside the reserved lubrication cavity, a threaded adjustment groove is provided at the middle position of the sliding body, a support screw is threadedly connected to the threaded adjustment groove, an airbag-type adjustment seat is installed on the slide rail base on both sides of the support screw, a reserved air pipe is provided at the bottom end of the airbag-type adjustment seat, and a manual air valve is installed on the reserved air pipe.

[0006] As a further technical solution of this utility model, mounting base plates are provided on both sides of the bottom of the slide rail seat, and screw holes are evenly provided on the mounting base plates.

[0007] As a further technical solution of this utility model, a rotary bearing is provided between the nylon wheel and the sliding body.

[0008] As a further technical solution of this utility model, the reserved lubrication cavity and the interior of the strip-shaped perforated plate are connected.

[0009] As a further technical solution of this utility model, the outer wall of the reserved lubrication cavity is fitted with a cover plate by screws.

[0010] As a further technical solution of this utility model, a door fixing component is provided at the top of the supporting screw, and screw holes are evenly provided at the edge of the door fixing component.

[0011] As a further technical solution of this utility model, the bottom edge of the door fixing member is evenly and movably connected with rollers that match the airbag type adjusting seat.

[0012] As a further technical solution of this utility model, the outer wall of the airbag-type adjustment seat is coated with a polytetrafluoroethylene coating, which improves the smoothness and strength of the surface of the airbag-type adjustment seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By incorporating threaded adjustment slots, the device optimizes its performance. Users can flexibly adjust the extension height of the support screws connected to the threads inside the three sets of sliding bodies according to the installation requirements of the sliding door. Then, using door fasteners with screw holes, the device is fixed to three positions at the bottom of the sliding door with screws. This facilitates horizontal calibration installation for different sliding doors through a three-point height adjustment structure and also makes it easy to adjust the installation height. Subsequently, the manual air valve is opened, and air is inflated into the airbag-type adjustment seat through the reserved air pipe. The airbag-type adjustment seat expands to press against the door fastener and the bottom of the sliding door after the installation height has been adjusted, improving the device's support effect for the sliding door. The elasticity of the airbag-type adjustment seat also enhances the device's buffering and shock absorption protection for the sliding door.

[0015] By installing nylon wheels, the device optimizes its structure. When the user pushes the sliding door, the nylon wheels on the sliding body at the bottom of the sliding door move inside the limiting groove on the slide rail. In this process, the rotary bearing between the nylon wheels and the sliding body can be used, and the strip-shaped perforated plate is evenly fixed on the inner wall of the limiting groove. The ball bearings that are in contact with the nylon wheels are evenly connected on the strip-shaped perforated plate. This converts the movement of the nylon wheels into rolling at the contact point, reduces the impact of frictional resistance, improves the smoothness of movement, reduces the frictional wear between the outer wall of the nylon wheels and the inner wall of the limiting groove, and extends the service life.

[0016] By incorporating ball bearings, the device operates with pre-drilled lubrication chambers containing lubricant on both sides of the slide rail. When the user pushes the sliding door, the ball bearings roll along with the sliding body. The ball bearings rub against the perforated plate, generating heat that is transferred to the lubricant on the outer wall of the perforated plate. This causes the lubricant to liquefy into an oily state and penetrate into the perforated plate, adhering to the outer walls of the ball bearings and nylon wheels. This achieves a self-lubricating protection effect, protecting the guide rail structure and reducing noise. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figure 1-5 An embodiment of this utility model is provided: an adjustable sliding door support rail structure, including a slide rail base 3, a limiting groove 9 is provided inside the slide rail base 3, a sliding body 8 is uniformly slidably connected inside the limiting groove 9, nylon wheels 7 are uniformly movably connected to both sides of the sliding body 8, a strip-shaped perforated plate 14 is uniformly fixed to the inner side wall of the limiting groove 9, and ball bearings 15 that are in contact with the nylon wheels 7 are uniformly movably connected to the strip-shaped perforated plate 14.

[0025] A rotary bearing 11 is provided between the nylon wheel 7 and the sliding body 8;

[0026] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, when the user pushes the sliding door to move, the nylon wheel 7 on the sliding body 8 installed at the bottom of the sliding door will move inside the limiting groove 9 on the slide rail seat 3. In this process, the rotary bearing 11 set between the nylon wheel 7 and the sliding body 8 can be used, and the strip-shaped perforated plate 14 is evenly fixed on the inner wall of the limiting groove 9, and the ball bearings 15 that are in contact with the nylon wheel 7 are evenly connected on the strip-shaped perforated plate 14. This can convert the movement of the nylon wheel 7 into the rolling of the contact point, reduce the influence of frictional resistance, thereby improving the smoothness of movement, and reducing the frictional wear problem between the outer wall of the nylon wheel 7 and the inner wall of the limiting groove 9, thus extending the service life.

[0027] Both sides of the slide rail seat 3 are provided with reserved lubrication chambers 5, and the reserved lubrication chambers 5 are filled with lubricating paste 13;

[0028] The lubrication cavity 5 and the internal structure of the strip perforated plate 14 are connected;

[0029] The outer wall of the reserved lubrication cavity 5 is fitted with a cover plate 12 by screws;

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, by providing reserved lubrication cavities 5 with lubricating paste 13 on both sides of the slide rail seat 3, when the user pushes the sliding door to move, the ball bearing 15 will roll along with the sliding body 8. The ball bearing 15 generates heat by rubbing against the strip porous plate 14, which is transferred to the lubricating paste 13 in contact with the outer wall of the strip porous plate 14, causing the lubricating paste 13 to liquefy into an oily state and seep into the interior of the strip porous plate 14, adhering to the outer wall of the ball bearing 15 and the nylon wheel 7. This enables the device to achieve a self-lubricating protection effect, protecting the guide rail structure through lubrication and reducing noise problems.

[0031] A threaded adjustment slot 10 is provided at the middle position of the sliding body 8. A support screw 6 is threadedly connected to the threaded adjustment slot 10. An airbag type adjustment seat 1 is installed on the slide rail seat 3 on both sides of the support screw 6. A reserved air pipe 17 is provided at the bottom of the airbag type adjustment seat 1. A manual air valve 18 is installed on the reserved air pipe 17.

[0032] Both sides of the bottom of the slide rail base 3 are provided with mounting base plates 4, and screw holes are evenly provided on the mounting base plates 4;

[0033] The top of the support screw 6 is provided with a door fastener 2, and screw holes are evenly provided on the edge of the door fastener 2;

[0034] The bottom edge of the door fastener 2 is evenly and movably connected with rollers 16 that match the airbag-type adjustment seat 1;

[0035] The outer wall of the airbag-type adjustment seat 1 is coated with a polytetrafluoroethylene coating, which improves the smoothness and strength of the surface of the airbag-type adjustment seat 1.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, users can flexibly adjust the extension height of the support screw 6 connected to the internal thread of the threaded adjustment slot 10 on the three sets of sliding bodies 8 according to the installation requirements of the sliding door. Then, the device and the three positions at the bottom of the sliding door are fixed by screws through the door fastener 2 with screw holes. This facilitates the horizontal calibration installation of different sliding doors through the three-point height adjustment structure, and also facilitates the adjustment of its installation height.

[0037] Working Principle: First, the user can flexibly adjust the extension height of the support screw 6 connected to the threaded adjustment slot 10 inside the three sets of sliding bodies 8 according to the installation requirements of the sliding door. Then, through the door fastener 2 with screw holes, the device is fixed to three positions at the bottom of the sliding door with screws. This facilitates the horizontal calibration installation of different sliding doors through the three-point height adjustment structure and also facilitates the adjustment of its installation height. Subsequently, the manual air valve 18 is opened, and air is inflated into the airbag-type adjustment seat 1 through the reserved air pipe 17, causing the airbag-type adjustment seat 1 to expand to a point where it presses against the door fastener 2 and the bottom of the sliding door after the installation height has been adjusted. This improves the device's support effect for the sliding door and also enhances the device's buffering and shock absorption protection for the sliding door by utilizing the elasticity of the airbag-type adjustment seat 1. At the same time, when the user pushes the sliding door to move, the nylon wheel 7 on the sliding body 8 installed at the bottom of the sliding door will move along with it inside the limiting groove 9 on the slide rail seat 3. In this process, the nylon wheel 7 and the The rotary bearing 11 arranged between the sliding bodies 8, and the strip-shaped perforated plate 14 evenly fixed on the inner wall of the limiting slide groove 9, with the ball bearings 15 evenly connected to the strip-shaped perforated plate 14 in contact with the nylon wheel 7, can convert the motion of the nylon wheel 7 into rolling at the contact point, reducing the impact of frictional resistance, thereby improving the smoothness of the motion, and reducing the frictional wear between the outer wall of the nylon wheel 7 and the inner wall of the limiting slide groove 9, thus extending the service life. In addition, by setting a retaining ring on both sides of the slide rail seat 3... The reserved lubrication cavity 5 contains lubricant 13. When the user pushes the sliding door to move, the ball bearing 15 will roll along with the sliding body 8. The ball bearing 15 generates heat by rubbing against the strip perforated plate 14, which is transferred to the lubricant 13 in contact with the outer wall of the strip perforated plate 14. This causes the lubricant 13 to liquefy into an oily state and seep into the interior of the strip perforated plate 14, adhering to the outer wall of the ball bearing 15 and the nylon wheel 7. This enables the device to achieve a self-lubricating protection effect, protecting the guide rail structure through lubrication and reducing noise problems.
