Description

Technical Field

[0001] This utility model belongs to the field of guide rail slider technology, and in particular relates to a dustproof slider. Background Technology

[0002] The combination of slider and linear guide is the core component for achieving high-precision linear motion in mechanical transmission, and is widely used in machine tools, automation equipment, 3D printers, industrial robots and other fields.

[0003] For example, Chinese patent CN221779845U discloses an anti-collision slider, which includes a slider body, mounting frames slidably connected to both the left and right ends of the slider body, locking screws threaded to the front end of the mounting frames, mounting blocks fixedly connected to both the front and rear ends of the mounting frames, and an anti-collision block installed at the end of the mounting block away from the slider body. The mounting frames are fixedly installed on the slider body by locking screws, without changing the structure of the slider body, making installation convenient and the performance good.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in use, such as: the device uses screws to fix the anti-collision block to the fixed block, which makes it impossible to fix the anti-collision block to the fixed block without tools; and the device relies on springs for cushioning, which releases stored elastic potential energy after cushioning, causing the cushioned object to bounce back. Therefore, we propose a dustproof slider. Utility Model Content

[0006] The purpose of this invention is to provide a dustproof slider to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a dustproof slider, including a slider, two fixing frames and two dustproof sealing gaskets, and further including:

[0008] Eight fixed blocks are respectively fixedly installed on two fixed frames. Each fixed block has a sliding groove, and a fixed column is fixedly installed in the sliding groove. Two sliding plates are slidably installed on the fixed column, and a damping rod fixed to the inner wall of the sliding groove is fixedly installed on one side of the sliding plate.

[0009] Eight sliding blocks are slidably installed in eight sliding grooves respectively. Two connecting rods are rotatably installed on one side of each sliding block. The connecting rods are rotatably connected to the corresponding sliding plates. Two dustproof sealing gaskets are fixedly installed on the slider.

[0010] A fixing component, located within the slider, is used to fix the positions of the two fixing frames.

[0011] In this technical solution, when it is necessary to install two fixed frames, the two fixed frames are placed on both sides of the slider. The fixed components can fix the position of the two fixed frames, which is convenient for the installation of the fixed frames. The operation is simple and convenient and does not require the use of tools.

[0012] When the entire device is impacted, four sliding blocks are squeezed and slide, which in turn squeezes the two connecting rods to rotate. The two connecting rods then drive the two sliding plates to slide and move away from each other. At the same time, all four damping rods are squeezed and contracted. The four damping rods can buffer the impact on the sliding blocks, ensuring the stable use of the slider and ensuring that the slider has a good anti-collision effect when the entire device is impacted.

[0013] In the above technical solution, the fixing component further includes:

[0014] A limiting groove is formed inside the slider. Two sliding rods are slidably installed inside the limiting groove. Two tension springs that are fixed to the inner wall of the limiting groove are fixedly installed on each of the two sliding rods. The ends of the two sliding rods that are far apart from each other pass through the limiting groove, and the ends of the two sliding rods that are far apart from each other are respectively inserted into two fixed frames.

[0015] A limiting post is fixedly installed in a limiting groove and located between two sliding rods. A sliding strip is slidably installed on the limiting post, and a second spring is sleeved on the limiting post. Both sliding rods are in contact with the sliding strip.

[0016] In this technical solution, when installing two fixed frames, firstly, the sliding bar is pulled towards the second spring, causing the second spring to compress and contract. When the sliding bar no longer compresses the two sliding rods, under the tension of the four springs, the two sliding rods slide and move closer to each other. Then, the two fixed frames are placed on both sides of the slider, and the four fixing bars are inserted into the two fixed frames, limiting their positions and ensuring that they can only slide up and down. Subsequently, the sliding bar is pulled away from the second spring, and under the rebound force of the second spring, its position is limited, ensuring that it will not shift without manual intervention. The sliding bar compresses the two sliding rods, causing them to slide away from each other. The two sliding rods are then inserted into the two fixed frames, fixing their positions and facilitating installation. The operation is simple and convenient, requiring no tools.

[0017] In the above technical solution, further, the two ends of the second spring are welded to the inner wall of the limiting groove and the sliding strip, respectively.

[0018] In this technical solution, the second spring is ensured to be used stably.

[0019] In the above technical solution, the sliding plate is slidably connected to the corresponding sliding groove, and the sliding strip is slidably connected to the limiting groove.

[0020] In this technical solution, it is ensured that the sliding plate can slide within the corresponding sliding groove, and that the sliding strip can slide within the limiting groove.

[0021] In the above technical solution, furthermore, two fixing strips are fixedly installed on each of the two dustproof sealing gaskets, and the four fixing strips are respectively inserted into the two fixing frames. The cross-section of the fixing strips is trapezoidal.

[0022] In this technical solution, the dustproof sealing gasket ensures that no dust will enter the slider during use.

[0023] In the above technical solution, furthermore, each of the eight fixed columns is fitted with two first springs, and the two ends of the first springs are respectively welded to the inner wall of the corresponding sliding groove and the corresponding sliding plate.

[0024] In this technical solution, under the action of the first spring's rebound force, the two sliding plates slide and move closer to each other, the four damping rods reset, the two sliding plates respectively squeeze the two connecting rods to rotate, and the two connecting rods squeeze the sliding block to reset.

[0025] In the above technical solution, the upper end of the sliding bar passes through the limiting groove and extends to the outside.

[0026] In this technical solution, it is convenient for staff to pull the slider.

[0027] The beneficial effects of this utility model are:

[0028] 1. This dustproof slider has two fixed frames placed on either side of the slider, with four fixing bars inserted into each frame to limit their position, ensuring they can only slide up and down. Pulling the sliding bars away from the second spring further limits their position, preventing displacement without manual intervention. The sliding bars press against the two sliding rods, causing them to slide away from each other. The two sliding rods then insert into the two fixed frames, securing their positions and facilitating installation. The operation is simple and convenient, requiring no tools.

[0029] 2. When the dustproof slider is impacted, four sliding blocks are compressed and slide, causing the sliding blocks to compress the two connecting rods to rotate. The two connecting rods then drive the two sliding plates to slide and move away from each other. At the same time, the two first springs and four damping rods are compressed and contracted. The four damping rods can buffer the impact on the sliding blocks, ensuring stable use of the slider. Subsequently, under the rebound force of the first springs, the two sliding plates slide and move closer to each other, the four damping rods return to their original position, and the two sliding plates compress the two connecting rods to rotate. The two connecting rods then compress the sliding blocks to return to their original position, ensuring good anti-collision effect of the slider when the entire device is impacted.
