[0002] In order to meet the accommodation needs of occasional visitors, a sofa bed is very necessary in small apartments. It refers to a piece of furniture that can be used for multiple purposes. The sofa bed can be placed in the living room or study to serve as a seat. When guests come at night, the multifunctional sofa bed can be unfolded and covered with bedding to become a bed, which greatly facilitates people's lives.

[0003] Deficiencies of existing technology: During use, the sofa push bed connects the main frame and the push bed structure through a slide rail structure to support and limit the push bed structure. However, during the production and processing of existing sofa push beds, the slide rail structure is installed between the sofa push bed armrest frame and the push bed structure. Therefore, a groove is reserved on the side of the push bed structure to facilitate the installation of the slide rail. At the same time, the slide rail structure is exposed to the outside of the sofa, affecting the overall aesthetics of the sofa push bed. Utility Model Content

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

[0006] Furthermore, a connecting bolt is threadedly connected to the side of the slide rail body, a roller is movably sleeved on the side of the connecting bolt, and the bottom end of the roller is movably connected to the inner wall of the side of the slide rail body.

[0007] Furthermore, the top end of the slide rail body is threadedly connected to a limit bolt.

[0008] Furthermore, a linear motor is fixedly connected to the top of the backrest frame, a linear track is fixedly connected to the inner side wall of the stretcher frame, and the side of the linear track is transmission-connected to the inner side wall of the linear motor.

[0009] Furthermore, the support frame is an L-shaped structure, and the side of the support frame maintains an appropriate distance from the side of the stretcher mechanism.

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

[0011] 1. This utility model connects the backrest and the pusher mechanism via the slide rail mechanism by attaching the slide rail mechanism to the inner side wall of the pusher mechanism, bolting the mounting bracket to the bottom end of the mounting plate, and attaching the slide rail body to the top end of the backrest frame. This ensures that the slide rail mechanism is completely concealed after the pusher mechanism is covered, thereby improving the overall aesthetics of the sofa pusher.

[0012] 2. This utility model uses a linear motor to drive the linear track, which in turn drives the stretcher frame. This causes the rollers to roll along the inner wall of the bottom end of the rail body, while the universal wheels simultaneously roll along the ground, thereby achieving telescopic movement of the stretcher mechanism. This simple operation also converts sliding friction into rolling friction, reducing wear on the rail mechanism and extending the service life of the stretcher. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solution of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The sofa push bed slide rail structure involved in the present invention is not limited to the various structures described in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Reference Figures 1 to 5 The utility model provides a sofa bed slide structure, including a backrest mechanism 1, and also includes: a slide mechanism 2, a bed pushing mechanism 3, an armrest 4, a support frame 5, a first hanger 6 and a second hanger 7. The side of the backrest mechanism 1 is movably connected to the side inner wall of the bed pushing mechanism 3 through the slide mechanism 2. The slide mechanism 2 is installed on the side inner wall of the bed pushing mechanism 3 to ensure that the slide mechanism 2 is completely hidden after the entire bed is covered with a skin. The bottom of the bed pushing mechanism 3 is close to the ground, ensuring that the surface of the bed pushing mechanism 3 is flat, improving the overall aesthetics. The slide mechanism 2 is installed at the top of the backrest mechanism 1, the support frame 5 is installed at the bottom of the backrest mechanism 1, the first hanger 6 is installed on the side of the support frame 5, the side of the armrest 4 is movably connected to the side of the support frame 5 through the first hanger 6, the second hanger 7 is installed on the side of the backrest mechanism 1, and the side of the backrest mechanism 1 is connected to the side of the armrest 4. Through the movably connected second hanger 7, the backrest mechanism 1 includes a backrest frame 101, the slide rail mechanism 2 includes a slide rail body 201 and a mounting frame 202, the bottom end of the slide rail body 201 is fixedly connected to the top of the backrest frame 101 by bolts, the stretcher mechanism 3 includes a stretcher frame 301, the top of the stretcher frame 301 is fixedly connected to a spring assembly 302, the bottom end of the stretcher frame 301 is fixedly connected to a universal wheel 303, the side inner wall of the stretcher frame 301 is fixedly connected to a mounting plate 305, the bottom end of the mounting plate 305 is fixedly connected to the top of the mounting frame 202 by bolts, the side of the mounting frame 202 is movably connected to the side of the slide rail body 201, when in use, the stretcher frame 301 is pulled to make the mounting frame 202 slide along the slide rail body 201, and the universal wheel 303 rolls along the ground, thereby realizing the extension and retraction of the stretcher frame 301.

[0021] Among them, the side of the slide rail body 201 is threadedly connected with a connecting bolt 204, and the side of the connecting bolt 204 is movably sleeved with a roller 205. The bottom end of the roller 205 is movably connected to the inner wall of the side of the slide rail body 201. The roller 205 is inserted into the inside of the slide rail body 201. When pushing and pulling the stretcher frame 301, the roller 205 rolls along the inner wall of the bottom end of the slide rail body 201. The connecting bolt 204 serves as a sliding component to reduce the friction between the slide rail body 201 and the mounting frame 202, thereby reducing wear.

[0022] Among them, the top of the slide rail body 201 is threadedly connected to the limit bolt 203, and the limit bolt 203 is located at both ends of the slide rail body 201. During installation, the limit bolt 203 passes through the top of the slide rail body 201 and is threadedly connected to the backrest frame 101 to limit the roller 205 and prevent the roller 205 from falling off from the inside of the slide rail body 201.

[0023] Among them, the top of the backrest frame 101 is fixedly connected to the linear motor 102, and the side inner wall of the stretcher frame 301 is fixedly connected to the linear track 304. The side of the linear track 304 is transmission-connected to the side inner wall of the linear motor 102. Starting the linear motor 102 drives the linear track 304 to move, thereby driving the stretcher mechanism 3 to slide along the backrest mechanism 1, thereby realizing the extension and retraction of the stretcher mechanism 3.

[0024] Among them, the support frame 5 is an L-shaped structure, and the side of the support frame 5 maintains an appropriate distance from the side of the stretcher mechanism 3. The armrest 4 is fixed to the side of the backrest mechanism 1 through the first hanger 6, the second hanger 7 and the support frame 5. When pushing and pulling the stretcher mechanism 3, the armrest 4 remains stationary.

[0025] The working principle of the present invention is as follows: by installing the slide rail mechanism 2 on the side inner wall of the push bed mechanism 3, ensuring that the slide rail mechanism 2 is completely hidden after the push bed is covered with a skin, when installing the slide rail mechanism 2, the mounting frame 202 is mounted on the bottom end of the mounting plate 305 by bolts, the slide rail body 201 is mounted on the top of the backrest frame 101, the rollers 205 on both sides are inserted into the slide rail body 201, and then the limit bolts 203 are passed through the top of the slide rail body 201 and are threadedly connected to the backrest frame 101, and the rollers 205 are screwed together. The bottom of the stretcher mechanism 3 is limited to the ground, ensuring that the surface of the stretcher mechanism 3 is flat and the overall aesthetics are improved. The armrest 4 is fixed to the side of the backrest mechanism 1 through the first hanger 6, the second hanger 7 and the support frame 5. When the stretcher mechanism 3 needs to be pushed or pulled, the linear motor 102 is started to drive the linear track 304 to move, thereby driving the stretcher frame 301 to move, causing the roller 205 to roll along the inner wall of the bottom end of the slide rail body 201, and at the same time the universal wheel 303 rolls along the ground, thereby realizing the extension and retraction of the stretcher mechanism 3.

[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.
