[0014] The beneficial effects of the utility model are as follows:

[0015] 1. This utility model uses two sets of sponges whose upper surfaces adhere to and abut against the lower surfaces of two sets of sliding mechanisms. This allows the two sets of sponges to absorb the noise generated during the rolling process of the two sets of sliding mechanisms. Then, two sets of U-shaped sound insulation panels are fitted onto the outer ends of the two sets of sliding mechanisms. This allows the two sets of U-shaped sound insulation panels to block the transmission of noise generated during the rolling process of the two sets of sliding mechanisms. The combined use of the two sets of U-shaped sound insulation panels and the two sets of sponges absorbs and blocks the noise generated by the sliding mechanisms during use, thereby effectively reducing the noise generated during the use of the three-section rail. This minimizes the impact of noise from the three-section rail on the user's mood and improves the overall user experience and satisfaction.

[0016] 2. This utility model utilizes the good elastic potential energy of the two sets of springs during use. This elastic potential energy drives the two sets of sliders, which in turn move the two sets of balls downwards. This ensures that the lower surfaces of the two sets of balls continuously abut against the upper surfaces of the two sets of sponges. This minimizes the risk of the second and third guide rails shifting when the thickness of the two sets of sponges narrows, thus preventing the three-section rail from wobbling during use. Therefore, it improves the stability of the three-section rail during use, helps extend the service life of the slide rail, and reduces maintenance and replacement costs. Attached Figure Description

[0026] As Figures 1 to 4 shown, a three-section slide rail with a sound elimination structure, comprising a three-section rail 1, the three-section rail 1 comprising a first guide rail 101, a second guide rail 102 and a third guide rail 103, the second guide rail 102 being slidably connected to the upper surface of the first guide rail 101, the third guide rail 103 being slidably connected to the upper end of the second guide rail 102, the inner wall top of the second guide rail 102 and the third guide rail 103 being provided with a sliding mechanism 3, the upper surface of the second guide rail 102 and the first guide rail 101 being provided with a groove, and the groove of the second guide rail 102 and the first guide rail 101 being provided with a sound elimination mechanism 2 for eliminating the sound generated during the sliding process of the second guide rail 102 and the third guide rail 103; specifically, the sound elimination mechanism 2 absorbs and blocks the noise generated by the sliding mechanism 3 during use, thereby effectively reducing the noise generated during use of the three-section rail 1, improving the overall experience and satisfaction of the user, and improving the practicality of the slide rail.

[0027] As Figure 1 andFigure 2 As shown, the sound attenuation mechanism 2 comprises two groups of sponges 202 and two groups of back-shaped soundproof boards 201, the two groups of back-shaped soundproof boards 201 are respectively installed on the inner wall top of the second guide rail 102 and the third guide rail 103, and are respectively sleeved on the outer end of the two groups of sliding mechanisms 3, the two groups of sponges 202 are respectively installed in the recess of the first guide rail 101 and the second guide rail 102, and the positions of the two groups of sponges 202 are respectively located at the lower end of the adjacent group of back-shaped soundproof boards 201; Specifically, the upper surfaces of the two groups of sponges 202 are abutted on the lower surfaces of the two groups of sliding mechanisms 3, so that the subsequent two groups of sponges 202 can absorb the noise generated during the rolling process of the subsequent two groups of sliding mechanisms 3, and the two groups of back-shaped soundproof boards 201 are sleeved on the outer end of the two groups of sliding mechanisms 3, so that the subsequent two groups of back-shaped soundproof boards 201 can block the propagation of the noise generated during the rolling process of the subsequent two groups of sliding mechanisms 3, and the two groups of back-shaped soundproof boards 201 and the two groups of sponges 202 are used in cooperation to absorb and block the noise generated during the use of the sliding mechanism 3, thereby effectively reducing the noise generated during the use of the three-section rail 1, so as to avoid the noise generated during the use of the subsequent three-section rail 1 from affecting the mood of the user, thereby improving the practicability of the sliding rail.

[0028] As shown in Figure 3 and Figure 4 The two groups of sliding mechanisms 3 each comprise a fixed sleeve 301, the two groups of fixed sleeves 301 are respectively installed on the inner wall top of the second guide rail 102 and the third guide rail 103, the inner wall top of the two groups of fixed sleeves 301 is provided with a spring 303, the inside of the two groups of fixed sleeves 301 is slidingly connected with a sliding block 302, the upper surface of the two groups of sliding blocks 302 is respectively provided with a spring 303, the lower surface of the two groups of sliding blocks 302 is provided with a recess, the recess inside the two groups of sliding blocks 302 is rotatably connected with a ball 304, and the lower surface of the two groups of balls 304 is respectively abutted on the upper surface of the two groups of sponges 202; Specifically, when the upper surface of the subsequent two groups of sponges 202 is damaged due to long-term friction and the thickness of the two groups of sponges 202 becomes narrow, the two groups of springs 303 have good elastic potential during use, so that the subsequent two groups of springs 303 can drive the two groups of sliding blocks 302 to move downward, and the lower surface of the subsequent two groups of balls 304 can continuously abut on the upper surface of the two groups of sponges 202, thereby avoiding the position of the second guide rail 102 and the third guide rail 103 from being deviated when the thickness of the subsequent two groups of sponges 202 becomes narrow, and causing the subsequent three-section rail 1 to shake during use, thereby improving the stability of the subsequent three-section rail 1 during use, prolonging the service life of the sliding rail, and reducing maintenance and replacement costs.

[0029] As shown in Figure 3As shown, the bottom corners on both sides of the two sets of U-shaped sound insulation panels 201 are all set with arc corners. Specifically, by setting the bottom corners on both sides of the two sets of U-shaped sound insulation panels 201 with arc corners, the bottom corners on both sides are designed to minimize the risk of the two sets of U-shaped sound insulation panels 201 sliding on the upper part of the two sets of sponges 202 while following the second guide rail 102 and the third guide rail 103, which could cause the two sets of sponges 202 to move and be damaged. This improves the service life of the two sets of sponges 202.

[0030] like Figure 1 and Figure 2 As shown, both sets of sponges 202 are made of absorbent sponge 202. Specifically, lubricating oil is poured onto the upper surface of sponge 202. Due to the absorbent nature of sponge 202, the lubricating oil penetrates and moves within the sponge 202. This allows the outer surface of the ball bearing 304 to quickly come into contact with the lubricating oil for lubrication during rolling, thus minimizing the risk of rust and corrosion of the two sets of ball bearings 304 during use and improving the service life of the slide rail.

[0031] like Figure 1 and Figure 2 As shown, a Z-shaped handle 4 is installed on the upper surface of the third guide rail 103. Specifically, by pulling the Z-shaped handle 4, the third guide rail 103 and the second guide rail 102 can slide quickly at the upper end of the first guide rail 101, so that the staff can quickly adjust and move the position of the third guide rail 103 and the second guide rail 102. This reduces the time and labor required for the staff to expand the three sections of rail 1 when the three sets of rails 101, 102 and 103 are combined and overlapped.

[0032] In summary: the upper surfaces of the two groups of sponges 202 abut against the lower surfaces of the two groups of sliding mechanisms 3, so that the subsequent two groups of sponges 202 absorb the noise generated during the rolling of the subsequent two groups of sliding mechanisms 3, and then the two groups of back-shaped soundproof boards 201 are sleeved on the outer ends of the two groups of sliding mechanisms 3, so that the subsequent two groups of back-shaped soundproof boards 201 block the propagation of the noise generated during the rolling of the subsequent two groups of sliding mechanisms 3, and the two groups of back-shaped soundproof boards 201 and the two groups of sponges 202 are used in cooperation to absorb and block the noise generated during the use of the sliding mechanism 3, thereby effectively reducing the noise generated during the use of the three-section rail 1; the two groups of springs 303 have good elastic potential during use, so that the elastic potential of the subsequent two groups of springs 303 drives the two groups of sliding blocks 302 to drive the two groups of balls 304 to move downward, thereby enabling the lower surfaces of the subsequent two groups of balls 304 to continuously abut against the upper surfaces of the two groups of sponges 202, so as to avoid the position deviation of the second guide rail 102 and the third guide rail 103 when the thickness of the subsequent two groups of sponges 202 narrows, and thereby causing the subsequent three-section rail 1 to shake during use.

[0033] At the same time, the lubricating oil is poured onto the upper surface of the sponge 202 by pouring lubricating oil, and the material of the sponge 202 is water-absorbing material, so that the subsequent lubricating oil moves in the sponge 202, thereby enabling the outer surface of the subsequent ball 304 to quickly contact and lubricate the lubricating oil during rolling, thereby avoiding rust and corrosion of the subsequent two groups of balls 304 during use, and at the same time, the smoothness of the sliding rail sliding is improved, thereby reducing the noise or abnormal sound of sliding.
