Description

Technical Field

[0001] The utility model belongs to the technical field of slide rails and relates to a concealed silent drawer slide rail. Background Art

[0002] A slide rail is an orbital system used to guide a sliding object to move along a straight track, and is commonly used in fields such as industry, construction, and transportation. The principle of the slide rail is to utilize the rolling or sliding of a slider or pulley on the track, enabling the object to move smoothly and accurately along a predetermined path.

[0003] For most existing concealed slide rails, since the slide rail is installed under the drawer, the friction is relatively large when the balls slide under pressure, resulting in generally poor sound insulation effects. Therefore, in order to improve the sound insulation effect, it is very necessary to design a concealed silent drawer slide rail. Summary of the Invention

[0004] The purpose of the utility model is to address the above problems existing in the prior art and propose a concealed silent drawer slide rail.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A concealed silent drawer slide rail includes an upper main body and a lower main body. It is characterized in that a protruding portion is provided at the midline position of the upper main body, and a number of first rolling beads are successively and spacedly installed at the midline position of the protruding portion. A number of second rolling beads are symmetrically and successively and spacedly installed on both sides of the protruding portion. Sound insulation strips one are installed on the upper main body on both sides of the protruding portion. A U-shaped groove corresponding to the protruding portion is provided at the midline position of the lower main body. A sound insulation strip two corresponding to the first rolling beads is installed at the midline position of the bottom of the U-shaped groove. Rolling grooves corresponding to the second rolling beads are provided on both sides inside the U-shaped groove, and sound insulation strips three and four are installed in the rolling grooves. A number of third rolling beads corresponding to the sound insulation strips one are successively and spacedly provided at the top of the U-shaped groove. A number of installation holes are provided at the edges of the upper main body and the lower main body.

[0006] The working principle of the utility model is as follows: After the first rolling beads, the second rolling beads, and the sound insulation strips one on the upper main body are respectively corresponded to the sound insulation strip two, the rolling grooves, and the third rolling beads on the lower main body and then inserted, first install the lower main body through the installation holes, and then fix the upper main body to the bottom of the drawer through the installation holes after pulling out the upper main body; when we pull the drawer, the first rolling beads, the second rolling beads, and the third rolling beads roll on the sound insulation strips one, the sound insulation strip two, and the sound insulation strip three respectively. During this period, the sound insulation strips one, two, three, and four reduce the sound generated by the rotation of each rolling bead, improving the sound insulation effect.

[0007] A space for the second rolling beads to move up and down inside is left in the rolling grooves, and the sound insulation strips three and four are respectively installed on the upper and lower sides inside the rolling grooves.

[0008] With the above structure, through the cooperation of the reserved space and the sound insulation gasket strip, the drawer has a certain buffer during movement.

[0009] An air guide groove is also provided at the top of the protruding part.

[0010] With the above structure, the air resistance during the push-pull of the drawer is reduced through the air guide groove.

[0011] The sound insulation gasket strip one, the sound insulation gasket strip two, the sound insulation gasket strip three and the sound insulation gasket strip four are made of rubber materials.

[0012] With the above structure, it has a certain buffering effect while sound insulation, reducing the wear of the rolling beads.

[0013] One end of the lower main body is of a closed structure.

[0014] With the above structure, the upper main body can only be inserted through the other end, playing a role of limiting.

[0015] Compared with the prior art, the present hidden silent drawer slide rail has the following advantages: By setting a structure in which a plurality of rolling beads cooperate with sound insulation gasket strips, while ensuring the sliding and supporting effects, the sound generated during the push-pull of the drawer can be greatly reduced, improving the silent effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0021] Such as Figures 1-3As shown in the figure, this hidden silent drawer slide rail includes an upper main body 1 and a lower main body 2. A protruding part 3 is provided at the midline position of the upper main body 1. A number of first rolling beads 4 are successively and spacedly installed at the midline position of the protruding part 3. A number of second rolling beads 5 are symmetrically and successively and spacedly installed on both sides of the protruding part 3. Sound insulation cushion strips 6 are installed on the upper main body 1 on both sides of the protruding part 3. A U-shaped groove 7 corresponding to the protruding part 3 is provided at the midline position of the lower main body 2.
