[0001] The utility model relates to the technical field of slide rails, and more particularly to a sofa slide rail device. Background Art

[0002] A sofa is a common piece of furniture. It is a multi-seat chair with soft cushions, generally used in living rooms. Generally, a sofa is long and narrow in shape. The sofa includes a base and a seat cushion. The base is used to make the seat cushion, which not only serves as a good decoration for the living room, but also provides a good place for people to relax. With the advancement of technology, the types of sofas are constantly increasing, among which retractable sofas are widely popular. The bottom cushion of the retractable sofa adopts a retractable structure, which can be stretched according to usage needs, increasing the seat cushion space and improving the comfort of the user.

[0003] Deficiencies of the existing technology: When the existing telescopic sofa is in use, the seat cushion is connected to the sofa frame through a slide rail. However, the slide rail device used in the existing telescopic sofa slides inside the slide rail through a slider. However, the slide rail device is a load-bearing component, and the slider exerts a large pressure on the slide rail, resulting in a large friction at the contact position, which is inconvenient to operate. At the same time, it will wear out after long-term use, affecting the overall stability of the sofa. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sofa slide rail device to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a sofa slide device, including a mounting mechanism, further including: a roller mechanism and a slide rail mechanism, the side surface of the mounting mechanism being movably connected to the side surface of the roller mechanism, the side surface of the roller mechanism being movably connected to the side inner wall of the slide rail mechanism, the mounting mechanism including a mounting frame, the side surface of the mounting frame being provided with a mounting hole, the roller mechanism including a bearing, the outer ring of the bearing being fixedly connected with an anti-slip ring, the inner ring of the bearing being fixedly connected with a connecting bolt, the side surface of the connecting bolt being movably connected to the side surface of the mounting hole, the side surface of the connecting bolt being threadedly connected with a fixing nut, the slide rail mechanism including a slide rail body, the side surface of the slide rail body being provided with a through groove, the bottom end of the anti-slip ring being movably connected to the bottom inner wall of the slide rail body, and the bottom end of the slide rail body being fixedly connected with a connecting plate.

[0006] Furthermore, the mounting mechanism is an L-shaped structure, and the mounting holes are evenly distributed on the side of the mounting frame.

[0007] Furthermore, the mounting mechanism and the slide rail mechanism are both made of aluminum alloy, and the anti-slip ring is made of elastic rubber.

[0008] Furthermore, a through hole is provided at the top of the mounting bracket, and a side surface of the through hole is movably connected to a limiting bolt.

[0009] Furthermore, the side of the connecting bolt is fixedly connected to a limiting ring, the side of the connecting bolt is movably sleeved with an adjusting ring, and the side of the adjusting ring is movably connected to the side of the mounting bracket.

[0010] Technical effects and advantages of this utility model:

[0011] 1. This utility model secures the two roller mechanisms to the sides of the mounting mechanism by passing connecting bolts through mounting holes near the end of the mounting bracket, and installing fixing nuts on the connecting bolts. Tightening the fixing nuts secures the two roller mechanisms to the sides of the mounting mechanism. The anti-skid rings on the sides of the two roller mechanisms are inserted into the interior of the slide rail body. Bolts are passed through the mounting holes at the top of the mounting bracket and the connecting plate, respectively, to secure the mounting mechanism and the slide rail mechanism to the sofa seat cushion and frame. During use, the mounting bracket is pulled to cause the anti-skid rings to roll along the bottom inner wall of the slide rail body. Bearings connecting the connecting bolts and the anti-skid rings reduce friction during rolling. The elastic rubber anti-skid rings increase friction between the roller mechanisms and the inner side walls of the slide rail body, preventing slippage and sliding wear. The elastic rubber has a certain degree of elasticity, providing excellent shock absorption and buffering, thereby providing stability to the mounting mechanism during sliding and reducing wear, thereby improving the stability of the slide rail and extending its service life.

[0012] 2. This utility model evenly distributes mounting holes on the side of the mounting frame. When installing the roller mechanisms, one is installed in a mounting hole near the end of the mounting frame, and the other is installed in a suitable mounting hole. The two roller mechanisms are kept at an appropriate distance. The installation direction of the mounting mechanism and the slide rail mechanism can be adjusted, that is, the mounting mechanism can be rotated 90 degrees and installed on the top or bottom of the sofa seat to meet different installation requirements, which helps to improve the flexibility and practicality of the slide rail.

[0020] Reference Figures 1 to 5The utility model provides a sofa slide device, including a mounting mechanism 1, further comprising: a roller mechanism 2 and a slide mechanism 3, the side surface of the mounting mechanism 1 is movably connected to the side surface of the roller mechanism 2, and the side surface of the roller mechanism 2 is movably connected to the side inner wall of the slide mechanism 3, the mounting mechanism 1 includes a mounting frame 101, a mounting hole 102 is opened on the side surface of the mounting frame 101, the roller mechanism 2 includes a bearing 202, the outer ring of the bearing 202 is fixedly connected with an anti-slip ring 201, the inner ring of the bearing 202 is fixedly connected with a connecting bolt 205, the side surface of the connecting bolt 205 is movably connected to the side surface of the mounting hole 102, and the side surface of the connecting bolt 205 is threadedly connected with a fixing nut 206, the slide mechanism 3 includes a slide rail body 301, a through groove 303 is opened on the side surface of the slide rail body 301, the bottom end of the anti-slip ring 201 is movably connected to the inner wall of the bottom end of the slide rail body 301, and the bottom end of the slide rail body 301 is fixedly connected with a connecting plate 302, which can be cut according to usage requirements. The mounting mechanism 1 and the slide rail mechanism 3 are of appropriate length. Two roller mechanisms 2 are selected. One of them passes through the mounting hole 102 near the end of the mounting frame 101 through the connecting bolt 205, and the fixing nut 206 is installed on the connecting bolt 205. The fixing nut 206 is tightened to fix the roller mechanism 2 to the side of the mounting mechanism 1. Similarly, the other roller mechanism 2 is installed. At the same time, the two roller mechanisms 2 maintain a suitable distance. The anti-slip rings 201 on the sides of the two roller mechanisms 2 are inserted into the inside of the slide rail body 301. The mounting mechanism 1 and the slide rail mechanism 3 are respectively installed on the sofa cushion and frame by passing the bolts through the mounting holes 102 and the connecting plate 302 at the top of the mounting frame 101. During use, the mounting frame 101 is pulled to make the anti-slip ring 201 roll along the inner wall of the bottom end of the slide rail body 301. At the same time, the bearing 202 connects the connecting bolt 205 and the anti-slip ring 201 to reduce the friction during rolling, thereby providing stability to the mounting mechanism 1 when sliding and reducing wear.

[0021] Among them, the mounting mechanism 1 is an L-shaped structure, and the mounting holes 102 are evenly distributed on the side of the mounting frame 101, which is convenient for adjusting the installation position of the roller mechanism 2. At the same time, the installation direction of the mounting mechanism 1 and the slide rail mechanism 3 can be adjusted according to needs, that is, the mounting mechanism 1 can be rotated ninety degrees and installed on the top or bottom of the sofa seat.

[0022] Among them, the mounting mechanism 1 and the slide rail mechanism 3 are both made of aluminum alloy material, which is light in weight, which is beneficial to reducing the overall weight of the sofa, and is cheap and reduces costs. The anti-slip ring 201 is made of elastic rubber, which increases the friction between the roller mechanism 2 and the inner wall of the side of the slide rail body 301 to avoid slipping and sliding wear. At the same time, the elastic rubber has a certain elasticity and can play a good shock-absorbing and buffering role.

[0023] Among them, a through hole 304 is opened at the top of the mounting frame 101, and the side of the through hole 304 is movably connected to a limiting bolt 305. The through holes 304 are set at both ends of the slide rail body 301. The limiting bolts 305 pass through the through holes 304 and are fixed on the sofa frame. When the slide rail body 301 is further fixed, the roller mechanism 2 is limited to prevent the roller mechanism 2 from falling off from the inside of the slide rail body 301.

[0024] Among them, the side of the connecting bolt 205 is fixedly connected to the limit ring 203, and the side of the connecting bolt 205 is movably sleeved with an adjusting ring 204. The side of the adjusting ring 204 is movably connected to the side of the mounting frame 101. According to the use requirements, the adjusting ring 204 of appropriate length is selected. When installing the roller mechanism 2, the adjusting ring 204 is located between the mounting frame 101 and the limit ring 203 to prevent the roller mechanism 2 from shaking, and at the same time, the anti-slip ring 201 maintains a suitable distance from the side of the mounting frame 101, which is convenient for adjustment when deviation occurs during the installation of the slide rail body 301 and the mounting frame 101.

[0025] The working principle of the present invention is as follows: according to the use requirements, the mounting mechanism 1 and the slide rail mechanism 3 of appropriate length are intercepted, two roller mechanisms 2 are selected, and the adjusting ring 204 of appropriate length is sleeved on the connecting bolt 205. One of them passes through the mounting hole 102 near the end of the mounting frame 101 through the connecting bolt 205, and the fixing nut 206 is installed on the connecting bolt 205. The fixing nut 206 is tightened to fix the roller mechanism 2 on the side of the mounting mechanism 1. The other roller mechanism 2 is installed in the same way. At the same time, the two roller mechanisms 2 maintain a suitable distance. The anti-slip rings 201 on the sides of the two roller mechanisms 2 are inserted into the interior of the slide rail body 301. The mounting mechanism 1 and the slide rail mechanism 3 are respectively mounted on the sofa cushion and the frame by passing bolts through the mounting holes 102 and the connecting plate 302 at the top of the mounting frame 101. The limiting bolts 305 are fixed to the sofa frame through the through holes 304. During use, the mounting frame 101 is pulled to make the anti-slip ring 201 roll along the inner wall of the bottom end of the slide rail body 301. The limiting bolts 305 limit the roller mechanism 2 to prevent the roller mechanism 2 from falling off from the inside of the slide rail body 301. At the same time, the connecting bolts 205 and the anti-slip ring 201 are connected through the bearing 202 to reduce the friction during rolling, thereby providing stability to the mounting mechanism 1 during sliding and reducing wear.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
