[0048] There are two groups of baffles 22, which are respectively located on both sides of the guide rail 20, and each group of guide rails includes two baffles 22, which are respectively located at both ends of the guide rail 20 and are symmetrically fixedly connected to the top wall of the base 11. The limit plate 25 is fixedly connected to the side wall of one end of the pull-out plate 12 and the limit plate 25 is located in the horizontal extension direction of the baffle 22. The sheath 26 is made of rubber material, and the sheath 26 is elastic. The sheath 26 is sleeved on the limit plate 25 and the sheath 26 and the limit plate 25 are interference fit. The limit plate 25 is located between the two baffles 22, and the two baffles 22 limit the sliding range of the pull-out plate 12.

[0049] In order to drive the pull-out plate 12 to move horizontally along the extension direction of the guide rail 20, a driving assembly is also provided, which includes: a driving motor 14, a first pulley 15, a second pulley 17, a toothed conveyor belt 18, and an engagement block 19. The driving motor 14 is fixedly connected to the side wall of the first fixed plate 13, and the first pulley 15 is fixedly connected to the output shaft of the driving motor 14.

[0050] The first pulley 15 and the second pulley 17 are toothed pulleys. A toothed conveyor belt 18 is provided with latching teeth, which are sleeved on the rollers of the first pulley 15 and the second pulley 17. The outer diameter surface of the first pulley 15 is provided with latching teeth, and the latching teeth on the toothed conveyor belt 18 are respectively engaged with the latching teeth of the first pulley 15 and the latching teeth of the rollers of the second pulley 17.

[0051] The engaging block 19 is connected to the bottom wall of the pull-out plate 12 by bolts and nuts. There is a gap between the engaging block 19 and the bottom wall of the pull-out plate 12. A part of the toothed conveyor belt 18 is slidably connected in the gap between the engaging block 19 and the bottom wall of the pull-out plate 12. A latch is provided on the upper surface of the engaging block 19, and the engaging block 19 is engaged with the toothed conveyor belt 18.

[0052] Working or installation process:

[0053] This application can be applied to objects such as desks, wine cabinets, drawers, etc.

[0054] When the pull-out plate 12 needs to be pushed out horizontally, the drive motor 14 is started, and the output shaft of the drive motor 14 drives the first pulley 15 to rotate, and the first pulley 15 rotates and drives the toothed conveyor belt 18 to transmit, and the toothed conveyor belt 18 drives the second pulley 17 to rotate through transmission, and the toothed conveyor belt 18 meshes with the meshing block 19 and drives the meshing block 19 to move horizontally along the extension direction of the toothed conveyor belt 18;

[0055] Since the engaging block 19 is fixedly connected to the pull-out plate 12 by bolts and nuts, the engaging block 19 drives the pull-out plate 12 to move, and the pull-out plate 12 drives the slider 21 to move. Since the slider 21 is slidably connected to the guide rail 20, and the pull-out plate 12 moves horizontally along the extension direction of the guide rail 20 (wherein the extension direction of the toothed conveyor belt 18 is the same as the extension direction of the guide rail 20), the drive motor 14 is started to drive the pull-out plate 12 to move horizontally to the side away from the drive motor 14, thereby achieving the purpose of horizontally pushing out the pull-out plate 12; wherein, the auxiliary wheel 24 and the disc of the second pulley 17 play an auxiliary sliding role for the pull-out plate 12, and play a supporting and balancing role for the middle part of the pull-out plate 12.

[0056] During the horizontal pushing out process of the pull-out plate 12, when the pull-out plate 12 drives the limit plate 25 to move to the side of the baffle 22 away from the driving motor 14, the limit plate 25 drives the sleeve 26 to move horizontally synchronously until the surface of the sleeve 26 is pressed and contacted with the side wall of the baffle 22. At this time, the baffle 22 away from the driving motor 14 limits the sleeve 26 in the horizontal direction. This is the farthest distance for the horizontal pushing out of the pull-out plate 12. The driving motor 14 stops running and the first pulley 15 stops rotating, completing the horizontal pushing out of the pull-out plate 12.

[0057] When it is necessary to retract the pull-out plate 12, the drive motor 14 is started in reverse and the output shaft of the drive motor 14 is rotated in the reverse direction. The pull-out plate 12 is moved toward the side close to the drive motor 14 through the above-mentioned transmission until the surface of the sheath 26 is pressed and contacted with the baffle 22 close to the drive motor 14. At this time, the drive motor 14 is turned off to complete the retraction of the pull-out plate 12.

[0058] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
