Description

Technical Field

[0001] This utility model belongs to the field of linear guide technology, specifically relating to a linear guide with a locking device. Background Technology

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Based on the nature of friction, linear motion guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides, among others.

[0003] A prior art patent, CN222122033U, describes a linear guide rail with a locking device. This patent includes a slide rail, a slider on the upper outer surface of the slide rail, and a locking mechanism on one side of the slider. The locking mechanism includes a threaded hole, a threaded rod, a U-shaped bracket, an L-shaped plate, a groove, an anti-slip pad, a guide rod, and a guide slot. The threaded rod is located on the upper outer surface of the slider, and a sealed bearing is provided between the threaded rod and the slider. The U-shaped bracket is located at the upper end of the slider, and the threaded hole is formed on the upper outer surface of the U-shaped bracket. In the middle, the two sets of L-shaped plates are fixedly installed on the lower end of the inner surface of both sides of the U-shaped frame. They have a locking structure to facilitate the limiting of the slider and avoid displacement, which would affect the stability of the placement. The anti-slip pad can increase resistance and improve anti-slip performance, bringing better application prospects. However, in actual use, there are still the following shortcomings: In practice, when using this patent, the limiting is achieved by rotating the threaded rod when locking the slider. The rotation process requires a large force to complete the limiting operation, which is relatively laborious and cannot guarantee the stability of the limiting.

[0004] Therefore, a linear guide rail with a locking device is needed to solve the problem that the locking and limiting operation in the existing technology is laborious and cannot guarantee the stability of the limiting. Utility Model Content

[0005] The purpose of this invention is to provide a linear guide rail with a locking device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a linear guide rail with a locking device, comprising a guide rail and a slider, the slider being slidably disposed on the guide rail, the slider having an installation groove, a rocker arm being disposed on the slider, the rocker arm being connected to a locking and limiting mechanism and disposed within the slider through the installation groove, the rocker arm and the locking and limiting mechanism locking and limiting the slider on the guide rail.

[0007] The locking and limiting mechanism includes an eccentric wheel, which is disposed in a mounting groove. An eccentric shaft is fixedly connected to the eccentric wheel. The top end of the eccentric shaft passes through the upper part of the slider and is connected to a rocker arm. The eccentric wheel is rotatably mounted in the mounting groove via the eccentric shaft. A sliding plate is fitted to the rear side of the eccentric wheel. A limiting groove is formed on the inner side of the sliding plate and passes through the rear side. A guide rod is slidably disposed in the limiting groove. The rear end of the guide rod is fixedly connected to the mounting groove. A connecting block is fixedly connected to the bottom of the sliding plate. A matching sliding groove is formed at the bottom of the connecting block corresponding to the bottom of the mounting groove. A spring is fixedly connected to the rear surface of the connecting block and fixedly installed in the mounting groove. Limiting blocks are movably disposed on the left and right sides of the connecting block in the mounting groove. Matching through grooves are formed on the limiting blocks corresponding to the slider. An anti-slip layer is fixedly connected to the outer surface of the limiting blocks. An inclined groove is formed on the limiting block. A connecting rod is slidably disposed in the inclined groove. The top end of the connecting rod is fixedly connected to the bottom of the sliding plate.

[0008] It should be noted in the solution that the eccentric shaft is located on the eccentric wheel near its outer periphery.

[0009] It is worth noting that the sliding plate is matched with the mounting groove and is slidably disposed within the slider through the mounting groove.

[0010] It should be further noted that the surface of the sliding plate near the eccentric wheel is curved.

Detailed Implementation

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a linear guide rail with a locking device, including a guide rail 1 and a slider 2. The slider 2 is slidably disposed on the guide rail 1. An installation groove 201 is provided in the slider 2. A rocker arm 3 is provided on the slider 2. A locking and limiting mechanism 4 is connected to the rocker arm 3 and disposed in the slider 2 through the installation groove 201. The rocker arm 3 and the locking and limiting mechanism 4 lock and limit the slider 2 on the guide rail 1.

[0023] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the locking and limiting mechanism 4 includes an eccentric wheel 401, which is located in the mounting groove 201. An eccentric shaft 402 is fixedly connected to the eccentric wheel 401. The eccentric shaft 402 is located on the eccentric wheel 401 near its outer periphery. The top end of the eccentric shaft 402 passes through the upper part of the slider 2 and is connected to the rocker arm 3. The eccentric wheel 401 is rotatably mounted in the mounting groove 201 through the eccentric shaft 402. A sliding plate is attached to the rear side of the eccentric wheel 401. 403, the sliding plate 403 is matched with the mounting groove 201 and is slidably disposed within the slider 2 through the mounting groove 201. The surface of the sliding plate 403 near the eccentric wheel 401 is arc-shaped. A limiting groove 407 is formed on the inner side of the sliding plate 403 and extends through to the rear side. A guide rod 408 is slidably disposed within the limiting groove 407. The rear end of the guide rod 408 is fixedly connected to the mounting groove 201. Two limiting grooves 407 are provided on the sliding plate 403 and are spaced apart from each other on the left and right. A connecting block 405 is fixedly connected to the bottom of the sliding plate 403. The bottom of the connecting block 405 is provided with a matching sliding groove 406 in the mounting groove 201. A spring 404 is fixedly connected to the rear surface of the connecting block 405 and fixedly installed in the mounting groove 201. Limiting blocks 4010 are movably provided on the left and right sides of the connecting block 405 in the mounting groove 201. The limiting blocks 4010 are symmetrically provided in the mounting groove 201 through the connecting block 405. The limiting blocks 4010 are slidably positioned on the upper limit of the slider 2 through the through groove 4013. The limiting blocks 4010 are provided with a matching through groove 4013 in the slider 2. An anti-slip layer 4011 is fixedly connected to the outer surface of the limiting block 4010. The anti-slip layer 4011 is made of rubber material. An inclined groove 4012 is provided on the limiting block 4010. A connecting rod 409 is slidably provided in the inclined groove 4012. The top end of the connecting rod 409 is fixedly connected to the bottom of the sliding plate 403.

[0024] In use, rotating the rocker arm 3 drives the eccentric shaft 402 to rotate, which in turn causes the eccentric wheel 401 to rotate. The rotation of the eccentric wheel 401 pushes the sliding plate 403. With the setting of the connecting block 405, it slides within the mounting groove 201 under the setting of the sliding groove 406. At the same time, with the limiting sliding setting of the guide rod 408 and the limiting groove 407, the sliding plate 403 slides stably within the mounting groove 201, which in turn drives the connecting rod 409 to move. The connecting rod 409 slides within the inclined groove 4012, and the inclined groove 4012 is set on the limiting block 4010. The connecting rod 409 slides within the inclined groove 4012 and pushes the limiting block 4010 to slide on the slider 2 through the through groove 4013. This causes the anti-slip layer 4011 to contact and rub against the guide rail 1 through the through groove 4013, thereby causing the slider 2 to slide and lock on the guide rail 1 for a limiting operation.

[0025] This solution has the following working process: When this device is in use, the slider 2 slides on the guide rail 1. When the slider 2 is locked and limited, the rocker arm 3 is rotated to drive the eccentric shaft 402 to rotate, which in turn causes the eccentric wheel 401 to rotate. The rotation of the eccentric wheel 401 pushes the sliding plate 403. Furthermore, through the setting of the connecting block 405, the sliding plate 403 is limited to slide within the mounting groove 201 under the setting of the sliding groove 406. Simultaneously, through the limiting sliding settings of the guide rod 408 and the limiting groove 407, the sliding plate 403 slides stably within the mounting groove 201, thereby driving... The connecting rod 409 moves and slides within the inclined groove 4012. The inclined groove 4012 is set on the limiting block 4010, which in turn causes the connecting rod 409 to slide within the inclined groove 4012 and push the limiting block 4010 to slide on the slider 2 through the through groove 4013. This causes the anti-slip layer 4011 to contact and rub against the guide rail 1 through the through groove 4013, thereby causing the slider 2 to slide and lock on the guide rail 1. The locking operation is simple and easy to implement, greatly improving its locking convenience. At the same time, the stable rotation of the rocker arm 3 ensures the locking stability of the slider 2.

[0026] In summary, by using the locking and limiting mechanism 4 on the slider 2 in conjunction with the rocker arm 3, the locking and limiting operation of the slider 2 can be completed conveniently and easily. Furthermore, through its locking operation, it can ensure that the slider 2 is stably limited on the guide rail 1, thereby achieving the convenience and stability of the device.
