[0023] The following will be combined with the attached embodiment of the present utility model Figure 1-2 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figure 1 to Figure 2 As shown, the utility model discloses a linear guide rail with a locking device, including a track bar 1 and a linear sleeve 2 slidably arranged on the periphery of the track bar 1, wherein the front and rear side walls of the sleeve are both slidably arranged with mounting blocks 3, and the mounting blocks 3 are located above the track bar 1, and a wiper 31 is fixedly arranged at the lower end of the mounting block 3.

[0026] At the same time, the linear sleeve 2 is also provided with a pressing block 41, an electromagnet 43 and a first elastic abutment 42. The pressing block 41, the electromagnet 43 and the first elastic abutment 42 are provided at the left and right ends of each mounting block 3. The specific structural relationship is as follows: the electromagnet 43 is fixedly arranged on the outside of the linear sleeve 2, the two pressing blocks 41 are arranged between the two electromagnets 43, and the first elastic abutment 42 is respectively abutted between the electromagnet 43 and the pressing block 41 to bring the two pressing blocks 41 closer to each other. The end face of the pressing block 41 facing the mounting block 3 is an inclined surface, and the mounting block 3 is abutted between the two pressing blocks 41. When the two pressing blocks 41 are close to each other, the two pressing blocks 41 will squeeze the mounting block 3 downward. In addition, in this structure, the pressure block 41 is made of iron metal, and correspondingly, a power supply end 44 is also provided on the linear sleeve 2, and the power supply end 44 is connected to the electromagnet 43. When the power supply end 44 supplies power to the electromagnet 43, the electromagnet 43 generates a magnetic force, and the pressure blocks 41 are each attracted by the electromagnet 43 on the same side and thus move away from the other pressure block 41; when the power supply end 44 stops supplying power, the magnetic force on the electromagnet 43 disappears, and the pressure blocks 41 approach each other again under the action of the first elastic supporting member 42 and push the mounting block 3 downward together.

[0027] In addition, a second elastic abutment 45 is previously provided on the linear sleeve 2. In this structure, the second elastic abutment 45 is used to push the mounting block 3 upwards so that the mounting block 3 can be reset upwards after the power supply end 44 is energized.

[0028] In this example, both the first elastic supporting member 42 and the second elastic supporting member 45 are springs.

[0029] The working principle of the above structure is as follows: when the linear guide rail is not working, the power supply end 44 is powered off, the two pressure blocks 41 will approach each other and push the mounting block 3 downward until the wiper 31 at the lower end of the mounting block 3 is pressed on the track bar 1. At this time, due to the friction between the wiper 31 and the track bar 1, the linear sleeve 2 cannot be easily displaced. When the linear guide rail starts to work, the power supply end 44 starts to supply power, so that the two pressure blocks 41 move away from each other. At this time, the second elastic supporting member 45 can push the pressure block 41 upward again, thereby making the wiper 31 leave the track bar 1, and the linear sleeve 2 can slide on the track bar 1 again.

[0030] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
