Description

Technical Field

[0001] The utility model relates to the technical field of drawer slide rails, in particular to a silent buffer three-section hidden rail which can be quickly assembled and disassembled. Background Art

[0002] When drawers do not have rails, they rub directly against the cabinet body, which causes greater friction. The surface of the rails is usually smooth and specially designed to reduce friction when the drawer is opened and closed.

[0003] Existing drawers are usually connected to hidden rails by screws. Drawer slides are important components connecting drawers and cabinet bodies. Their structural design not only affects the drawer's pushing and pulling smoothness, load-bearing capacity and stability, but also directly affects the drawer's ease of disassembly and assembly. In order to ensure the stability of drawer sliding, more complex connection methods and locking mechanisms are often required to ensure that the drawer does not accidentally slip or shake during use. However, this makes the drawer's disassembly and installation more cumbersome and inconvenient for later disassembly and maintenance of the drawer. Therefore, a new hidden rail structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a silent and buffered three-section hidden rail that can be quickly assembled and disassembled, so as to solve the problem raised in the above background technology that existing drawers are usually fixed to the hidden rails by screws. Although this enhances stability, it makes the disassembly and installation of the drawers more cumbersome and inconvenient for subsequent maintenance of the drawers.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a silent buffer three-section hidden rail that can be quickly assembled and disassembled, comprising:

[0007] A track assembly, the track assembly comprising a mounting rail, a first sliding rail, and a second sliding rail, wherein the side of the mounting rail is movably connected to the first sliding rail, and the outside of the first sliding rail is movably connected to the second sliding rail;

[0008] A quick disassembly and assembly component includes a rectangular placement slot, a spring and a limit block. A rectangular placement slot is opened at one end of the top of the second sliding rail. One end of the spring is fixedly connected to the second sliding rail at both ends of the bottom of the rectangular placement slot, and the other end of the spring is fixedly connected to the limit block. The limit block is movably connected in the rectangular placement slot.

[0009] Furthermore, the quick disassembly assembly also includes a baffle, and the other end of the top of the second sliding rail is fixedly connected to the baffle.

[0010] Furthermore, the quick disassembly assembly further comprises a clamping hole, and clamping holes are provided on both sides of the bottom of the limiting block, and one end of a spring is fixedly connected in the clamping hole.

[0011] Furthermore, the quick disassembly and assembly assembly also includes a limiting groove and a slider. The limiting grooves are opened at the second sliding rails on both sides of the rectangular placement groove. The sliders are fixedly connected to the two sides of the limiting block, and the sliders are movably connected to the limiting grooves.

[0012] Furthermore, the track assembly also includes a first receiving groove, a first T-shaped block, a second receiving groove and a second T-shaped block. The first receiving groove is opened on the side of the mounting rail, the side of the first sliding rail is fixedly connected to the first T-shaped block, the first T-shaped block is movably connected in the first receiving groove, the upper and lower ends of the first sliding rail are opened with second receiving grooves, the upper and lower ends of the inner surface of the second sliding rail are fixedly connected to the second T-shaped block, and the second T-shaped block is movably connected in the second receiving groove.

[0013] Furthermore, it also includes a silent sliding component, which includes a slot and a steel ball. The upper and lower ends of the sides of the first sliding rail and the second sliding rail are both provided with a slot, and the slot movably engages the steel ball.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The utility model cooperates with the limit block pushed upward by the spring and the baffle to limit and fix the drawer. When the limit block is pressed downward, the limit block can slide into the rectangular placement groove when the spring is compressed, and then the drawer can be pulled outward, so that the drawer can be quickly disassembled; when the drawer is slid inward, when the drawer moves to one side of the limit block, the spring pushes the limit block out, so that the drawer can be quickly installed, thereby improving the efficiency of disassembly and assembly of the drawer.

[0016] Based on the above beneficial effects, the steel balls are provided as rolling bodies, which directly act between the mounting rail, the first sliding rail and the second sliding rail. Compared with the sliding friction of the traditional drawer sliding directly on the rail, the friction force of the rolling friction is smaller, and the small friction force means that the friction noise generated during the movement will be greatly reduced; at the same time, the steel balls can play a certain buffering role between the rails. When the drawer is opened and closed at a fast speed or is impacted by external force, the steel balls can absorb part of the energy through their own rolling, thereby reducing the collision force between the drawer and the rail.

[0045] The arrangement of the slot 301 provides a guarantee for the steel ball 302 to roll when contacting the first sliding rail 102 and the second sliding rail 103 .

[0046] Working principle: Due to the restriction of the limit block 203 and the baffle 204 on the drawer, when the drawer is pulled outward, the steel balls 302 on the second sliding rail 103 and the first sliding rail 102 roll to realize the movement of the second sliding rail 103 and the first sliding rail 102, and the drawer is pulled out. When the drawer needs to be disassembled, the limit block 203 is pressed downward. At this time, the spring 202 is compressed, and the limit block 203 moves to the rectangular placement groove 201. When the top of the limit block 203 coincides with the top of the rectangular placement groove 201, the drawer is pulled outward to realize the drawer. Disassembly; placing the drawer between the limit block 203 and the baffle 204, that is, the installation of the drawer is achieved. This step can realize the rapid disassembly and assembly of the drawer, while reducing noise and alleviating the collision force of the drawer. It is worth mentioning that since the limit block 203 protrudes from the surface of the second sliding rail 103, and the force of pulling the drawer outward in daily life is horizontally outward, no external force will be applied to the top of the limit block 203 to cause the limit block 203 to move downward, and the limit block 203 will not enter the placement groove 201, thereby not affecting the normal storage of the drawer.
