Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of linear slide rails, specifically a linear slide rail buffer mechanism. Background Technology
[0002] Buffer slides are widely used transmission and connection components in furniture manufacturing. Existing buffer slides generally have a buffer device, which mainly consists of a buffer spring, a fastening block, and a buffer cylinder. To make the buffer device more compact, the buffer spring, fastening block, and buffer cylinder are mounted on a buffer seat composed of a front and rear buffer section. The buffer spring and cylinder are located at the rear buffer section, and the fastening block is located at the front buffer section.
[0003] However, existing cushioning devices have significant drawbacks. The cushioning cylinder is typically housed within the cushioning seat, or the cylinder body is integrally molded with the cushioning seat. Users cannot disassemble or assemble the cushioning cylinder according to actual usage conditions, resulting in extremely poor adaptability of the cushioning device. Utility Model Content
[0004] The purpose of this invention is to provide a linear slide rail buffer mechanism to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A linear slide rail buffer mechanism includes a base, on which two sets of symmetrically arranged slide rails are mounted. Slider blocks are slidably connected to the slide rails, and mounting bolts are fixedly connected within the sliders. A mounting bracket is provided inside the slider, and an insertion slot is provided within the mounting bracket. The mounting bolt is disposed within the insertion slot, and a clamping nut that mates with the mounting bolt is disposed within the insertion slot. An adjustment slot is fixedly connected to the mounting bracket, and a connecting block is disposed between the adjustment slots. A copper tube is fixedly connected to the bottom of the connecting block. A fixing seat is fixedly connected to the base, and an electromagnet is fixedly connected between the fixing seats. The copper tube is slidably connected to the outer wall of the electromagnet, and a controller is mounted on the control end of the electromagnet. Adjusting bolts are fixedly connected to both sides of the connecting block, and the adjusting bolts are disposed within the adjustment slots, with adjusting nuts threaded through the adjustment slots.
[0007] As a further improvement of this utility model, the slide rail is provided with mounting holes.
[0008] Compared with the prior art, the beneficial effects of this utility model are: this utility model buffers the inertial force generated when the slider slides by the hysteresis effect between the copper tube and the magnet. At the same time, the magnitude of the hysteresis force between the copper tube and the magnet can be precisely controlled by adjusting the magnetic field strength on the magnet, thereby achieving precise buffering of the slide rail. Furthermore, this utility model can improve the adaptability of the equipment by setting the adjustment groove, thus improving the practicality of the equipment. Attached Figure Description

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] See Figures 1-4In this embodiment of the utility model, a linear slide rail buffer mechanism includes a base 1, on which two sets of symmetrically arranged slide rails 2 are mounted. A slider 4 is slidably connected to the slide rail 2, and a mounting bolt 5 is fixedly connected inside the slider 4. A mounting bracket 7 is provided inside the slider 4, and an insertion slot 8 is provided inside the mounting bracket 7. A mounting bolt is disposed in the insertion slot 8, and a clamping nut 6 that cooperates with the mounting bolt 5 is disposed in the insertion slot 8. An adjustment slot 9 is fixedly connected to the mounting bracket 7, and a connecting block 10 is disposed between the adjustment slots 9. A copper tube 13 is fixedly connected to the bottom of the connecting block 10. A fixing seat 14 is fixedly connected to the base 1, and an electromagnet 15 is fixedly connected between the fixing seats 14. The copper tube 13 is slidably connected to the outer wall of the electromagnet 15, and a controller 16 is installed on the control end of the electromagnet 15. Adjusting bolts 11 are fixedly connected to both sides of the connecting block 10, and the adjusting bolts 11 are disposed in the adjustment slots 9. Adjusting nuts 12 are threadedly connected to the adjusting bolts 11 through the adjustment slots 9.
[0016] This invention firstly achieves linear movement of the slider 4 by sliding the slider 4 to the slide rail 2. Then, the mounting bracket 7 is clamped and fixed to the slider 4 by the threaded connection of the mounting bolt 5 and the clamping nut 6. Next, the relative distance between the two sets of adjusting grooves 9 is adjusted according to the different relative widths between the two sets of slide rails 2. At this time, the relative position of the connecting block 10 is adjusted by the sliding connection of the adjusting bolt 11 and the adjusting groove 9, thereby keeping the copper tube 13 between the two sets of slide rails 2. Then, the two sets of adjusting grooves 9 are clamped by the threaded connection of the adjusting bolt 11 and the adjusting nut 12, thereby achieving a tight connection between the connecting block 10 and the adjusting groove 9, thus realizing the adaptive installation and fixation between the copper tube 13 and the slider 4.
[0017] When the slide rail 2 slides, the controller 16 de-energizes the electromagnet 15. At this time, the electromagnet 15 loses its power and magnetization. The electromagnet 15 and the copper tube 13 slide relative to each other, which does not hinder the relative sliding between the slider 4 and the slide rail 2. Then, when the slider 4 stops and loses its drive, the controller 16 controls the electromagnet 15 to be energized. At this time, eddy currents are generated between the electromagnet 15 and the copper tube 13. The inertial force generated by the slider 4 acts on the copper tube 13 through the mounting bracket 7 and the adjusting groove 9, and then the inertial force is offset and buffered by the hysteresis effect generated by the eddy current.
[0018] In one instance of this embodiment, please refer to Figures 1-4 The slide rail 2 is provided with mounting holes 3, which facilitates the installation of the slide rail 2 and the base 1.
[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
