[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A linear guide rail with a locking device includes a guide rail body 1. The guide rail body 1 has a sliding block 4 slidably disposed on it. A splicing mechanism is installed at the end of the guide rail body 1. The splicing mechanism facilitates the splicing of the linear guide rail, improving its usability. A locking mechanism is installed on the guide rail body 1. When the sliding block 4 needs to be locked, the locking mechanism increases the friction between the pressing plate 21 and the sliding block 4, facilitating the locking of the sliding block 4. The splicing mechanism includes a first groove 32, which is located at the end of the guide rail body 1. The first groove 32 is square-shaped and is used to support the sliding of a slider 33.

[0024] In detail, the inner wall of the first groove 32 is slidably provided with two sliders 33. The sliders 33 are used to support the installation of the insert plate 31 and the push rod 36. A spring 34 is fixedly installed between the two sliders 33. The spring 34 is used to provide force.

[0025] Furthermore, the slider 33 is fixedly mounted with two insert plates 31 and two push rods 36 on its side. The insert plates 31 are square plates and are designed to be inserted into the slots 38 to achieve the splicing of the linear guide rail. The push rods 36 are cylindrical rods and there are two push rods. One end of the push rods 36 penetrates the surface of the guide rail body 1 and is used to drive the slider 33 to move.

[0026] Furthermore, one end of the guide rail body 1 is provided with a positioning groove 35, which is a square block. The positioning groove 35 is designed to receive the insertion of the positioning block 39. The other end of the guide rail body 1 is fixedly installed with a positioning block 39, which is also a square block. The positioning block 39 is designed to be inserted into the positioning groove 35 to achieve positioning and splicing between the guide rail bodies 1.

[0027] More specifically, the other end of the guide rail body 1 is provided with a second groove 37. The second groove 37 is square in shape and is provided to receive the insertion of the slider 33. The inner wall of the second groove 37 is provided with two slots 38. The two slots 38 are square in shape and are provided to receive the insertion of one end of the insert plate 31.

[0028] In general, the locking mechanism includes a cavity 23, which is located inside the guide rail body 1. The cavity 23 is designed to support the installation of the motor 24 and also to limit the movement of the lifting block 25. The cavity 23 is a square groove. The motor 24 is fixedly installed on the inner wall of the cavity 23. The motor 24 has forward and reverse rotation functions. The motor 24 is designed to drive the lead screw 26 to rotate. The lead screw 26 is fixedly installed on the shaft end of the motor 24. The lead screw 26 is designed to drive the lifting block 25 to move linearly along the inner wall of the cavity 23.

[0029] Finally, a lifting block 25 is threaded onto the lead screw 26. The lifting block 25 is square in shape and slides on the inner wall of the cavity 23. The lifting block 25 is used to support the installation of the extrusion plate 21. The extrusion plate 21 is fixedly installed on the top of the lifting block 25. The extrusion plate 21 is square in shape and is used to extrude the sliding block 4, thereby achieving the purpose of locking the sliding block 4. A storage groove 22 is provided on the guide rail body 1. The storage groove 22 is connected to the cavity 23. The extrusion plate 21 is located in the storage groove 22. The storage groove 22 is used to support the placement of the extrusion plate 21.

[0030] Working method: When linear guides need to be spliced, press the lever 36 on the first guide body 1 in opposite directions. The lever 36 will drive the insert plate 31 to move in opposite directions through the slider 33 until the insert plate 31 moves to the appropriate distance. Then, insert the positioning block 39 at one end of the second guide body 1 into the positioning groove 35 on the first guide body 1. After the insertion is completed, release the lever 36. The insert plate 31 will be inserted into the slot 38 under the action of the spring 34, thus completing the splicing of the linear guides. The operation is simple and convenient.

[0031] When the sliding block 4 needs to be locked, the motor 24 is started. The motor 24 drives the lead screw 26 to rotate. The lead screw 26 drives the lifting block 25 to slide linearly along the inner wall of the cavity 23. During the linear movement, the lifting block 25 will drive the extrusion plate 21 to move until the extrusion plate 21 contacts the sliding block 4 and extrudes the sliding block 4, thereby achieving the purpose of locking the sliding block 4.
