Description

Technical Field

[0001] This utility model belongs to the field of slide rail technology, and in particular relates to a linear slide rail with a buffer function. Background Technology

[0002] Slide rails are commonly seen in daily work, such as in CNC machine tools, fixture devices, and stamping devices. The installation of slide rails helps to provide smooth and precise linear motion, support or guide the entry and exit of objects, and ensure the stability and reliability of the device.

[0003] A search revealed a linear slide rail with a buffer and anti-collision function in patent document CN221628654U, but it still has the following shortcomings in practical use:

[0004] 1. The linear slide rail with buffer and anti-collision function disclosed in the patent document with patent publication number CN221628654U has multiple cylindrical grooves on both sides of the slider. Springs are installed inside the cylindrical grooves. One end of the spring is connected to the slider, and the other end of the spring is connected to a telescopic column. The end of the telescopic column is connected to an anti-collision plate. When the slider collides with an object, the object will collide with the anti-collision plate, the spring will be compressed, and the movement speed of the slider will be reduced to achieve the buffering effect. However, when the speed of the slider is too high, the anti-collision plate will collide with the slider, reducing the anti-collision effect of the slider and reducing the buffering effect.

[0005] 2. The linear slide rail with buffer and anti-collision function disclosed in the patent document with patent publication number CN221628654U has a slider that is slidably connected on the slide rail body. However, the slider has a simple structure, which is not convenient for protecting the parts that need to be protected. This makes the parts that need to be protected susceptible to adverse effects from external factors, causing damage, or even adversely affecting the buffer.

[0006] To address these issues, we provide a linear guide rail with a buffer function. Utility Model Content

[0007] The purpose of this utility model is to provide a linear slide rail with a buffer function. By setting a buffer component, bidirectional buffering of the slider is achieved, improving the buffering effect. Furthermore, by setting a protective component, the air nozzle is hidden and protected, extending the service life of the air nozzle and preventing air leakage caused by air nozzle damage. This is beneficial for buffering and thus solves the technical problem mentioned in the background art of the linear slide rail with buffer and anti-collision function disclosed in the patent document with patent publication number CN221628654U.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model relates to a linear slide rail with a buffer function, comprising a slider, on which mounting grooves are symmetrically opened on both side walls, and on which buffer components are symmetrically arranged, each buffer component including an air bladder disposed inside the mounting groove, with an air nozzle mounted on the air bladder penetrating parallel through the side wall of the slider; and on which protective components are symmetrically arranged on the side wall of the slider, each protective component including a screw fixed parallel to the corner of the side wall of the slider, with a protective cover fixed to the side wall of the lug threadedly connected to the circumference of the screw, the position of the protective cover corresponding to the position of the air nozzle.

[0010] The present invention is further configured such that a linear guide rail body is disposed below the slider, and movable wheels equidistantly distributed on the lower surface of the slider are movably disposed on the upper surface of the linear guide rail body.

[0011] The present invention is further configured such that the connecting rods vertically connected at the four corners of the lower surface of the slider have rotatably connected rollers on their periphery, and the linear guide rail body has symmetrically opened guide grooves on both side walls, with the rollers movably disposed inside the guide grooves.

[0012] The present invention is further configured such that the upper surface edge of the linear guide body has symmetrically fixed limiting blocks, and the limiting blocks are arranged along the width direction of the linear guide body.

[0013] The present invention is further configured such that the side wall of the slider has a rectangular array of holes and slots, the damper connected in parallel inside the holes and slots has a damping spring sleeved on its periphery, the outer end of the protruding rod connected to the outer end of the damper has a connected anti-collision plate, and the outer side wall of the anti-collision plate has an anti-collision pad.

[0014] The present invention is further configured such that the mounting groove is a U-shaped structure, the airbag is a U-shaped structure, and the airbag protrudes outward from the mounting groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up a buffer component, when the anti-collision plate comes into contact with a foreign object, the shock-absorbing spring and damper work together to slow down the movement speed of the slider and prevent the slider from directly contacting and colliding with the limit block. When the movement speed of the slider slows down, the anti-collision plate comes into contact with the airbag, further slowing down the movement speed of the slider, effectively preventing the anti-collision plate from contacting and colliding with the slider, achieving the purpose of bidirectional buffering and anti-collision, improving the buffering effect, and improving the safety of the slider during movement.

[0017] 2. This utility model, by setting up a protective component, allows for the replenishment of gas into the airbag when the protective cover is rotated clockwise. The protective cover moves in an arc around the screw as a fixed point, releasing the obstruction of the air nozzle and allowing gas to be replenished into the airbag through the air nozzle. Conversely, rotating the protective cover counterclockwise hides the protective air nozzle, effectively preventing the air nozzle from being contacted or collided with by external objects, extending the service life of the air nozzle, avoiding airbag leakage caused by air nozzle damage, and providing cushioning.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The linear guide rail body 101 is used to limit the movement trajectory of the slider 1, effectively preventing the slider 1 from deviating during movement. The cooperation of the roller 102a and the moving wheel 103 effectively reduces the friction between the slider 1 and the linear guide rail body 101, effectively reducing wear. The limiting block 101a is used to prevent the slider 1 from disengaging from the linear guide rail body 101.

[0030] Specifically, a slider 1 is provided on the top of the linear guide body 101, a guide groove 101b is provided on the long side wall of the linear guide body 101, a limiting block 101a is fixedly connected in the width direction on the upper surface of the linear guide body 101, a movable wheel 103 is connected to the lower surface of the slider 1, the movable wheel 103 is movably mounted on the linear guide body 101, a vertically connected connecting rod 102 is provided at the corner of the lower surface of the slider 1, a rotatably connected roller 102a is provided around the connecting rod 102, the roller 102a is movably mounted inside the guide groove 101b, an installation groove 104 is provided on the long side wall of the slider 1, and a hole groove 105 is provided at the corner of the long side wall of the slider 1.

[0031] Furthermore, two limiting blocks 101a are symmetrically arranged, two guide grooves 101b are symmetrically opened, four connecting rods 102 are arranged in a rectangular array, moving wheels 103 are distributed at equal intervals, two mounting grooves 104 are symmetrically arranged, and four hole grooves 105 are arranged in a rectangular array.

[0032] The operation process of this embodiment is as follows: push the slider 1, the roller 102a moves along the guide groove 101b, the moving wheel 103 moves on the linear guide body 101, and the slider 1 moves.

[0033] Example 2

[0034] Please see Figure 1 and Figure 3Based on the first specific embodiment, a buffer assembly 2 is provided. The buffer assembly 2 includes a crash plate 201, an airbag 202, a damper 203 and a shock-absorbing spring 203a, which effectively prevents the crash plate 201 from colliding with the slider 1, further improving the buffering and anti-collision effect and enhancing the safety of the slider 1 during movement.

[0035] Specifically, the anti-collision plate 201 is arranged parallel to the side of the slider 1. There is an anti-collision pad 201a on one side wall of the anti-collision plate 201. The outer end of the damper 203 is connected to the protrusion rod 203b. The outer end of the protrusion rod 203b is connected to the anti-collision plate 201. The damper 203 is connected inside the slot 105. There is a shock-absorbing spring 203a sleeved on the periphery of the damper 203. The airbag 202 is arranged inside the mounting slot 104. The air nozzle 202a connected to the airbag 202 penetrates the side wall of the slider 1.

[0036] Furthermore, the two anti-collision plates 201 are symmetrically arranged, the two airbags 202 are symmetrically arranged, and the four dampers 203 are arranged in a rectangular array.

[0037] The operation process of this embodiment is as follows: When the anti-collision plate 201 comes into contact with an external object, the anti-collision plate 201 will move towards the slider 1. Through the cooperation of the damper 203 and the shock absorption spring 203a, the movement speed of the slider 1 is effectively reduced. When the speed of the slider 1 is reduced to a relatively slow speed, after the anti-collision plate 201 comes into contact with the airbag 202, the airbag 202 will once again provide shock absorption and buffer for the anti-collision plate 201, further reducing the movement speed of the slider 1 and preventing the anti-collision plate 201 from directly contacting and colliding with the slider 1.

[0038] Example 3

[0039] Please see Figure 1 , Figure 4 and Figure 5 Based on specific embodiment one and specific embodiment two, a protective component 3 is provided. The protective component 3 includes a protective cover 301, an ear seat 301a and a screw 302. The protective cover 301 is used to hide the air nozzle 202a, which protects the air nozzle 202a and increases the service life of the air nozzle 202a.

[0040] Specifically, the screw 302 is connected to the side wall of the slider 1. The screw 302 has a threaded lug 301a on its periphery. The lug 301a has a fixed protective cover 301 on its side wall. The protective cover 301 corresponds to the position of the air nozzle 202a.

[0041] Furthermore, the two screws 302 are symmetrically arranged, and the screws 302 are disposed on the width sidewall of the slider 1;

[0042] The operation process of this embodiment is as follows: when it is necessary to replenish the airbag 202 with gas, rotate the protective cover 301 clockwise so that it rotates around the screw 302 as the axis, thereby removing the obstruction of the air nozzle 202a; after replenishment, rotate the protective cover 301 counterclockwise to hide the air nozzle 202a again. This design can effectively prevent the air nozzle 202a from being damaged by external force collision, avoid air leakage of the airbag 202, and thus ensure the stability of the buffer function.
