Description

Technical Field

[0001] This application relates to the field of track buffer technology, and more particularly to a track buffer. Background Technology

[0002] To avoid excessive force when closing the cabinet, a damper is necessary to reduce the impact force. Cabinet doors equipped with this user-friendly accessory prevent noise when closing and protect the cabinet. The main purpose of damper products is to reduce the impact force between the door panel and the cabinet, extend the life of the door panel, and reduce noise during operation, creating a quiet and comfortable indoor environment.

[0003] However, in existing track buffers, the upper buffer component is connected to the track as a whole. Therefore, when the buffer is damaged, the entire track must be replaced, which reduces the utilization rate of the device. Therefore, in order to correct the above defects, we propose a track buffer. Utility Model Content

[0004] In view of the above problems, this application provides a track buffer to solve the problem of the upper buffer being integrally connected to the track. Therefore, when the buffer is damaged, only the entire track can be replaced, which reduces the utilization rate of the device.

A damper is fixedly connected to the inner wall of the positioning chamber. One side of the damper is fixedly connected to the inner wall of the positioning chamber, and a buffer block is fixedly connected to the other side of the damper. The other side of the buffer block penetrates the side wall of the positioning chamber. A spring is sleeved on the damper. The two ends of the spring are fixedly connected to the inner wall of the positioning chamber and the side wall of the buffer block, respectively. A positioning block is fixedly connected to the bottom of the positioning chamber. A pair of first bolts pass through the positioning block. A threaded groove matching the first bolts is provided on the side wall of the limiting plate, and a U-shaped block is sleeved on the limiting plate. A stabilizing block is fixedly connected to the side wall of the U-shaped block, and the stabilizing block extends into the sliding groove.

[0006] In some embodiments, two pairs of second bolts pass through the limiting plate, and the two pairs of second bolts are symmetrically arranged about the central axis of the limiting plate.

[0007] In some embodiments, a liquid filling chamber is provided on the side wall of the limiting plate, an injection block is provided in the liquid filling chamber, a hand handle is fixedly connected to one side of the injection block, and a plurality of injection holes are provided on the top of the slide groove.

[0027] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] This application provides a rail buffer, including a limiting plate 1: the limiting plate 1 has a sliding groove 2, and a positioning chamber 3 is provided on one side of the limiting plate 1. A damper 4 is fixedly connected to the inner wall of the positioning chamber 3. One side of the damper 4 is fixedly connected to the inner wall of the positioning chamber 3, and a buffer block 5 is fixedly connected to the other side of the damper 4. The other side of the buffer block 5 penetrates the side wall of the positioning chamber 3. A spring 6 is sleeved on the damper 4. The two ends of the spring 6 are fixedly connected to the inner wall of the positioning chamber 3 and the side wall of the buffer block 5, respectively. A positioning block 7 is fixedly connected to the bottom of the positioning chamber 3. A pair of first bolts 8 pass through the positioning block 7. A threaded groove matching the first bolts 8 is provided on the side wall of the limiting plate 1, and a U-shaped block 9 is sleeved on the limiting plate 1. A stabilizing block 10 is fixedly connected to the side wall of the U-shaped block 9 and extends into the sliding groove 2.

[0029] In the technical solution of this application embodiment, when it is necessary to add lubricating oil to the slide 2, the drawer is pulled out and the injection block 13 is taken out by the hand lever 14. At this time, lubricating oil is added to the liquid filling chamber 12, and then the injection block 13 is inserted into the liquid filling chamber 12. Then, the injection block 13 is pushed by the hand lever 14, and the injection block 13 squeezes the lubricating oil, thereby adding the lubricating oil into the slide 2 through the injection hole 15. Therefore, it is not necessary to disassemble the limiting plate 1. Two pairs of second bolts 11 pass through the limiting plate 1. The two pairs of second bolts 11 are symmetrically arranged about the central axis of the limiting plate 1. The liquid filling chamber 12 is opened on the side wall of the limiting plate 1. The injection block 13 is provided in the liquid filling chamber 12. The hand lever 14 is fixedly connected to one side of the injection block 13. Several injection holes 15 are opened on the top of the slide 2.

[0030] In the technical solution of this application embodiment, the injection holes 15 are equidistantly arranged to improve the coverage of lubricating oil addition. Several injection holes 15 are equidistantly distributed on the top of the slide groove 2. Anti-slip texture is provided on the handle 14. A vertical block 16 is fixedly connected to the top of the U-shaped block 9. A third bolt 17 passes through the vertical block 16.

[0031] Working principle: In use, the pair of limiting plates 1 are symmetrically installed into the drawer cabinet by setting the second bolt 11. Then, the U-shaped block 9 is installed onto the drawer by the third bolt 17. The U-shaped block 9 is then fitted onto the limiting plate 1, and the stabilizing block 10 is inserted into the slide groove 2. When the drawer is closed, the drawer slides until the U-shaped block 9 hits the buffer block 5. The buffer block 5 compresses the spring 6 and the damper 4, thereby reducing the impact force on the drawer through the spring 6 to protect the drawer. When it is necessary to add lubricating oil to the slide groove 2, the drawer is pulled out, and the injection block 1 is taken out by the handle 14. 3. At this time, lubricating oil is added to the filling chamber 12, and then the injection block 13 is inserted into the filling chamber 12. Then, the injection block 13 is pushed by the hand lever 14. The injection block 13 squeezes the lubricating oil, and thus the lubricating oil is added to the slide groove 2 through the injection hole 15. Therefore, it is not necessary to disassemble the limiting plate 1. When the buffer needs to be replaced, the second bolt 11 is unscrewed, the limiting plate 1 is removed, the first bolt 8 is then unscrewed, the positioning chamber 3 is removed, the new positioning chamber 3 is placed on one side of the limiting plate 1, and the positioning block 7 and the positioning chamber 3 are screwed back on by the first bolt 8, thereby improving the convenience of replacing the buffer.
