[0017] By adopting the above technical solution, it can effectively ensure the structural strength of the first guide rail, the second guide rail and the third guide rail.

[0018] (III) Beneficial effects

[0019] The present utility model has the following beneficial effects compared with the prior art:

[0020] To solve the problem that the three-section guide rail for table drawers mainly consists of three guide rails that are sleeved together and can slide relative to each other step by step. Although this kind of three-section guide rail can realize the convenient pulling and pushing of the table drawer during use, during the pulling and pushing process, since the guide rails are in direct sliding contact with each other, and since the guide rails are mainly made of stainless steel, it causes a relatively large noise during use. At the same time, as the use time of the guide rails increases, it is easy for wear to occur between the guide rails, shortening the service life of the three-section guide rail. The present utility model installs sound-absorbing components between the first guide rail and the second guide rail, and between the second guide rail and the third guide rail respectively. So that when this kind of three-section guide rail is used, under the action of the ball and the silicone sound-absorbing strip, it can effectively reduce the noise during the sliding and pulling of the second guide rail and the third guide rail, and at the same time, it also makes the frictional resistance during the sliding and pulling of the second guide rail and the third guide rail smaller, avoiding the drawback that this kind of three-section guide rail is prone to wear during use, and extending the service life of the three-section guide rail.

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] As Figures 1 - 3 shown, a new type of three - section guide rail in this embodiment includes a guide rail one 1. A slide groove one 3 is opened in the middle of one side wall of the guide rail one 1. A guide rail two 7 is installed in the slide groove one 3. A slide groove two 4 is opened in the middle of the side wall of the guide rail two 7 facing away from the guide rail one 1. A guide rail three 6 is installed in the slide groove two 4. The slide groove one 3 can ensure the convenient sliding of the guide rail two 7 in the guide rail one 1, and the slide groove two 4 can ensure the convenient sliding of the guide rail three 6 in the guide rail two 7. Sound - damping components 8 are installed between the upper and lower sides of the guide rail two 7 and the guide rail one 1, and between the upper and lower sides of the guide rail three 6 and the guide rail two 7. The sound - damping component 8 includes an installation groove 803 opened in the guide rail one 1 and the guide rail two 7, a ball 801 installed in the installation groove 803, and a silicone sound - damping strip 802 arranged under the ball 801. The ball 801 contacts the silicone sound - damping strip 802, which can effectively reduce the resistance and noise during the sliding of the guide rail two 7 and the guide rail three 6.

[0028] As Figures 1 - 3 shown, in this embodiment, a fixing bolt one 2 is installed on one side inside the guide rail one 1, and a fixing bolt two 5 is installed on the side of the guide rail three 6 away from the guide rail two 7. The fixing bolt one 2 is mainly used to fix the guide rail one 1 on the side wall of the storage space on the table body, and the fixing bolt two 5 is mainly used to connect the guide rail three 6 with the outer wall of the shaft - used drawer.

[0029] As Figures 1 - 3As shown, in this embodiment, the ball 801 is rotatably connected to the mounting groove 803, and the ball 801 extends out of the mounting groove 803, which can ensure the convenient rotation of the ball 801 relative to the mounting groove 803. The second guide rail 7 and the third guide rail 6 are respectively bonded to the corresponding silicone sound-absorbing strips 802, and the mating part of the silicone sound-absorbing strip 802 and the ball 801 is an arc-shaped concave structure.

[0030] As Figures 1 - 3 shown, in this embodiment, the second guide rail 7 is provided with a plastic clip connected to the slider on the first guide rail 1, and the third guide rail 6 is provided with a plastic clip connected to the slider on the second guide rail 7. Such a design can facilitate the convenient disassembly and assembly of the second guide rail 7 and the third guide rail 6.

[0031] As Figures 1 - 3 shown, in this embodiment, the first guide rail 1, the second guide rail 7 and the third guide rail 6 are all made of stainless material. The first fixing bolt 2 passes through the first guide rail 1, and the second fixing bolt 5 passes through the third guide rail 6, which can effectively ensure the structural strength of the first guide rail 1, the second guide rail 7 and the third guide rail 6.

[0032] The specific implementation process of this embodiment is as follows: During use, first install the first guide rail 1 on the storage space in the table body, and assemble the second guide rail 7 and the third guide rail 6 in sequence. Then, just fix the third guide rail 6 to the outer wall of the table drawer, and the three-section guide rail can be put into use. During the use process, sound-absorbing components 8 are respectively installed between the first guide rail 1 and the second guide rail 7, and between the second guide rail 7 and the third guide rail 6. When the three-section guide rail of this structure is in use, under the action of the ball 801 and the silicone sound-absorbing strip 802, the noise generated during the sliding and pulling of the second guide rail 7 and the third guide rail 6 can be effectively reduced. At the same time, the frictional resistance during the sliding and pulling of the second guide rail 7 and the third guide rail 6 is also smaller, avoiding the disadvantage that the three-section guide rail of this structure is prone to wear during use, and prolonging the service life of the three-section guide rail.
