Description

Technical Field

[0001] This utility model relates to the field of linear guide rail technology, and in particular to a guide rail locking mechanism. Background Technology

[0002] Linear guides, also known as linear guides or linear slides, are mechanical devices used to achieve high-precision linear reciprocating motion. They consist of two parts: a guide rail and a slider. The rolling motion of rolling elements between the two replaces traditional sliding friction, thereby significantly reducing motion resistance and improving motion accuracy and efficiency. Automatic locking of the guide rail is also widely used to supplement the function of the guide rail, playing an irreplaceable role in fields such as industrial automation, semiconductor manufacturing, and medical equipment.

[0003] An existing patent (publication number: CN218935037U) discloses that "this utility model provides a guide rail locking mechanism, belonging to the field of automation electromechanical technology, including a slide rail, on which a slider body is slidably arranged. The slider body is characterized by having four locking units at its lower part, with two locking units distributed on each side of the slide rail. Each locking unit includes a housing disposed on the lower side wall of the slider body, a lower inclined plate inside the housing, two steel balls disposed on two inclined surfaces of the lower inclined plate, a driving unit disposed within the housing on one side of the steel balls, a T-shaped frame disposed on one outer wall of the lower inclined plate, a top column disposed at the lower part of the T-shaped frame, the top column passing through the outer side wall of the housing, and a return unit disposed on the inner side wall of the housing outside the T-shaped frame. This utility model can quickly achieve automatic locking, and the locking structure is small and compact."

[0004] In the process of realizing this application, the inventors discovered the following problems with the existing technology: the existing guide rail locking mechanism requires the cooperation of nail heads, upper and lower inclined plates, steel columns, T-shaped frames, top columns, compression springs and other components to achieve the locking and unlocking functions. The overall structure is relatively complex with many parts. During long-term use, there is sliding friction between the steel column and the inclined surface, which is prone to wear after long-term use, affecting the locking accuracy and stability, and thus increasing the cost of maintenance and replacement of parts.

[0005] Therefore, those skilled in the art have provided a guide rail locking mechanism to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a guide rail locking mechanism. The movement of the connecting block, connecting frame, rotating block, and fixed block can be controlled by the extension and retraction of the cylinder output end, realizing the rapid locking and unlocking of the slider. The whole process is smooth and responsive, improving work efficiency. It is also relatively simple and convenient for subsequent maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A guide rail locking mechanism includes a slider, a fixing mechanism on one side of the slider, the fixing mechanism including a connecting frame, two connecting blocks fixedly disposed on the side of the connecting frame near the slider, a rotating block rotatably disposed on the side of each of the two connecting blocks near the connecting frame, and a fixing block rotatably disposed on the opposite side of each of the two rotating blocks.

[0009] Both ends of the slider are fixedly provided with connecting shells, and one side of one of the two connecting shells is fixedly provided with an installation block. A cylinder is fixedly provided on the side of the installation block near the connecting shell.

[0010] Furthermore, guide blocks are fixedly provided at both the upper and lower ends of the two fixed blocks, and one side of the connecting frame is located on the side of the slider away from the cylinder.

[0011] Furthermore, guide grooves are provided at both the upper and lower ends of the two connecting shells, and multiple guide blocks are slidably disposed inside the multiple guide grooves.

[0012] Furthermore, the connecting bracket is slidably disposed on the side of the two connecting shells away from the cylinder, with the side of the connecting bracket near the slider being slidably disposed on the opposite side of the two connecting shells, with the opposite sides of the two fixing blocks being slidably disposed on the opposite side of the two connecting shells.

[0013] Furthermore, the two connecting blocks are slidably disposed inside the two connecting shells respectively, and one side of one of the two connecting blocks is fixedly disposed at the cylinder output end.

[0014] Furthermore, a rubber block is fixedly provided at one end of each of the two fixed blocks, and an anti-slip texture is fixedly provided at one end of each of the two rubber blocks.

[0015] Furthermore, a slide rail is provided at the lower end of the slider, and the two rubber blocks are positioned at opposite ends of the slide rail.

[0016] This utility model has the following beneficial effects:

[0017] 1. The guide rail locking mechanism proposed in this utility model extends the cylinder output end when locking the slider, pushing the connecting block and the connecting frame to slide, causing the rotating block to rotate. The rotation of the rotating block will push the fixed block to slide relative to each other inside the connecting shell. During the sliding process of the fixed block, the rubber block gradually approaches the slide rail, and then contacts and applies pressure to it, finally locking the slider. This simplifies the transmission process and improves the reliability and stability of the mechanism.

[0018] 2. The guide rail locking mechanism proposed in this utility model activates the cylinder when unlocking the slider, causing its output end to retract, which in turn causes the connecting block to slide the connecting frame, thereby pulling the rotating block to rotate inside the connecting shell. This gradually releases the locking of the fixed block and the rubber block on the slide rail, allowing the slider to slide freely. The overall components are relatively few, making it easier to troubleshoot and repair when a fault occurs. Replacing parts is also more convenient, reducing maintenance costs.

[0025] 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.

[0026] Reference Figures 1-4 One embodiment provided by this utility model:

[0027] A guide rail locking mechanism includes a slider 1. A fixing mechanism 4 is provided on one side of the slider 1. The fixing mechanism 4 includes a connecting frame 401. Two connecting blocks 406 are fixedly provided on the side of the connecting frame 401 near the slider 1. A rotating block 407 is rotatably provided on the side of the two connecting blocks 406 near the connecting frame 401. A fixing block 403 is rotatably provided on the opposite side of the two rotating blocks 407.

[0028] Both ends of the slider 1 are fixedly provided with connecting shells 2. One side of one of the two connecting shells 2 is fixedly provided with a mounting block 405. The side of the mounting block 405 near the connecting shell 2 is fixedly provided with a cylinder 404.

[0029] Guide blocks 408 are fixedly installed at both the upper and lower ends of the two fixed blocks 403. One side of the connecting frame 401 is located on the side of the slider 1 away from the cylinder 404. Guide grooves 409 are opened at both the upper and lower ends of the two connecting shells 2. Multiple guide blocks 408 are slidably installed in the multiple guide grooves 409. The side of the connecting frame 401 near the slider 1 is slidably installed in the two connecting shells 2 away from the cylinder 404. The opposite sides of the two fixed blocks 403 are slidably installed in the two connecting shells 2 on opposite sides. The two connecting blocks 406 are slidably installed in the two connecting shells 2. One side of the two connecting blocks 406 is fixedly installed at the output end of the cylinder 404. Rubber blocks 402 are fixedly installed at opposite ends of the two fixed blocks 403. Anti-slip textures are fixedly installed at opposite ends of the two rubber blocks 402. A slide rail 3 is provided at the lower end of the slider 1. The opposite ends of the two rubber blocks 402 are located at the front and rear ends of the slide rail 3.

[0030] Specifically, when the slider 1 needs to be locked, the cylinder 404 on one side of the mounting block 405 is activated, and its output end extends to push the connecting block 406 and the connecting frame 401 to slide along the inner wall of the connecting shell 2. The sliding of the connecting frame 401 will drive the connecting block 406 connected to it on the other side to slide synchronously in the corresponding connecting shell 2. As the connecting block 406 slides, the rotating block 407 rotates in the connecting shell 2 under the action of thrust, which in turn pushes the fixed block 403 to slide along the internal guide structure of the connecting shell 2. During this process, the guide block 408 on the fixed block 403 is precisely embedded in the guide groove 409 inside the connecting shell 2 to ensure smooth sliding without deviation. Finally, the rubber block 402 at the lower end of the fixed block 403 gradually presses the front and rear ends of the slide rail 3. Through the elastic deformation of the rubber and the anti-slip texture, a strong friction force is formed to achieve a firm lock between the slider 1 and the slide rail 3.

[0031] During unlocking, the output end of cylinder 404 retracts, causing connecting block 406 to slide in the opposite direction and pulling connecting frame 401 to move synchronously. Connecting block 406 on the other side moves in tandem. The reverse movement of connecting block 406 pulls rotating block 407, causing it to rotate in the opposite direction within connecting shell 2. This causes fixed block 403 to drive rubber block 402 to slide in the opposite direction along guide groove 409, gradually releasing the pressure on slide rail 3. Slider 1 can then slide freely again, completing the unlocking process. Throughout the entire operation, the components work closely together to achieve reliable locking and releasing functions.

[0032] The cylinder 404-driven locking method shortens the operation time compared to traditional manual locking, requiring only a few seconds from start to lock or unlock. This improves equipment operating efficiency, reduces operator workload, and minimizes locking errors caused by human error. It also reduces maintenance costs and downtime due to improper operation, improving overall production management efficiency. Furthermore, the elasticity of the rubber block 402 makes it highly adaptable to uneven surfaces and minor wear on the slide rail 3, maintaining a stable locking effect under various working conditions. In addition, the locking force can be flexibly adjusted by regulating the output pressure of the cylinder 404 to suit different load requirements and application scenarios. The overall structure is relatively simple, facilitating subsequent maintenance and reducing manufacturing costs. Wear-resistant copper sleeves or grease coatings are provided at the rotating connections of the rotating block 407, connecting block 406, and fixed block 403 to reduce frictional wear during long-term use and extend the life of the mechanism. Content not described in detail in this specification is prior art known to those skilled in the art.

[0033] Working principle: When it is necessary to lock the slider 1, the cylinder 404 is activated, and its output end extends to push the connecting block 406 and the connecting frame 401 to slide inside the connecting shell 2. The sliding of the connecting frame 401 will drive another connecting block 406 connected to it to slide synchronously inside another connecting shell 2. The sliding of the connecting block 406 will push the rotating block 407 to rotate inside the connecting shell 2. The rotation of the rotating block 407 will push the fixed block 403 to slide relative to each other inside the connecting shell 2. When the fixed block 403 slides, the guide block 408 will slide in the guide groove 409 inside the connecting shell 2. The sliding of the fixed block 403 will gradually cause the rubber block 402 at its lower end to squeeze the front and rear ends of the slide rail 3 to achieve locking.

[0034] Secondly, when it is necessary to unlock slider 1, cylinder 404 is activated, causing its output end to retract, which causes connecting block 406 to slide inside connecting shell 2 and drives connecting frame 401 connected to it to move synchronously, so that another connecting block 406 moves synchronously. During the movement, connecting block 406 will pull rotating block 407, causing it to rotate inside connecting shell 2, so that fixing block 403 drives rubber block 402 to slide in the opposite direction inside connecting shell 2, so that fixing block 403 gradually releases the lock on slide rail 3.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
