[0024] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-7 The utility model discloses a miniature linear guide rail that is easy to splice, including a guide rail 1 and a moving pair 2 arranged on the guide rail 1; the moving pair 2 includes a slider 21 that can move back and forth along the length direction of the guide rail 1, and a plurality of first balls 22 that abut against the guide rail 1 are arranged in the slider 21. The slider 21 is detachably provided with end covers 23 at both ends of the slider 21 in the length direction of the guide rail 1, and a retainer 24 for preventing the first balls 22 from being separated from the slider 21 is detachably provided between the two end covers 23, and an oil scraper 25 that penetrates the end cover 23 and is inserted into the slider 21 is detachably provided at one end of the end cover 23 away from the slider 21, and a clamping component 26 that is clamped with the oil scraper 25 and can prevent the oil scraper 25 from being away from the slider 21 is detachably provided on one side of the slider 21 relative to the top of the guide rail 1.

[0026] The utility model provides a clamping assembly 26 that can clamp two oil scraping blades 25 at the same time, so that the two oil scraping blades 25 can be locked and restricted at the same time after the oil scraping blades 25 on both sides are installed, and the end cover 23 is blocked and restricted by the oil scraping blade 25, so that the end cover 23 is locked synchronously, thereby saving splicing steps and improving splicing convenience.

[0027] In one embodiment, the oil scraper 25 includes an oil scraper plate 251 and a latch 252 disposed on a side of the oil scraper plate 251 close to the end cover 23. A through hole is provided in the end cover 23 for the latch 252 to pass through. A slot is provided in the slider 21 for the latch 252 to be inserted. After the oil scraper plate 251 and the slider 21 are in contact with the end cover 23, the end of the latch 252 away from the oil scraper plate 251 is inserted into the slot.

[0028] The clamping assembly 26 includes a base 261, and two limit blocks 262 are arranged on one side of the base 261 close to the latch 252. A groove 27 for the clamping assembly 26 to move up and down is arranged on one side of the slider 21 relative to the top of the guide rail 1. A limit groove for the limit block 262 to be inserted is arranged on one end of the latch 252 away from the oil scraper 251.

[0029] When the moving pair 2 is located on the guide rail 1 , the limiting block 262 is inserted into the limiting groove and the height of the limiting block 262 in the limiting groove is greater than the distance between the base 261 and the top of the guide rail 1 .

[0030] Such a design ensures that when the assembled moving pair 2 is assembled to the guide rail 1 for use, the downward movement space of the snap-in assembly 26 is limited by the guide rail 1, and thus it cannot be disengaged from the oil scraper blade 25 during operation. Therefore, the snap-in assembly 26 can securely lock the oil scraper blade 25 without the need for an additional locking mechanism, so that the entire assembly operation does not require additional tools, further improving the convenience and efficiency of assembly.

[0031] It should be noted that both the limit groove and the limit block 262 are provided with inclined chamfers for assisting the limit block 262 to be inserted into the limit groove, so that the limit block 262 can be inserted into the limit groove under the guidance of the inclined chamfer when it is not fully aligned with the limit groove, thereby reducing the accuracy required for splicing.

[0032] In a specific implementation, a stepped groove may be provided at the bottom of the base 261 , and the cross-sectional area at the bottom of the stepped groove is smaller than the cross-sectional area at the top of the stepped groove, so that maintenance personnel can insert a screwdriver into the stepped groove to pry the base 261 away from the groove 27 .

[0033] In one embodiment, an auxiliary assembly component 28 located between two limit blocks 262 is provided on one side of the base 261 close to the latch 252; the auxiliary assembly component 28 includes a rubber column 281 threadedly provided on the base 261 and a second ball 282 detachably provided between the base 261 and the rubber column 281; a recessed groove for the second ball 282 to be inserted into is provided at one end of the rubber column 281 close to the base 261; the bottom end of the second ball 282 is located at the bottom of the base 261; and an assembly groove for the rubber column 281 to be inserted into and in close contact with the rubber column 281 is provided in the slider 21;

[0034] When the moving pair 2 is located on the guide rail 1 , the second ball 282 abuts against the top of the guide rail 1 .

[0035] Such a design enables the clamping assembly 26 to be temporarily fixed by utilizing the friction between the rubber column 281 and the slider 21 after the clamping assembly 26 is spliced ​​with the slider 21, thereby preventing the spliced ​​movable pair 2 from loosening during installation on the guide rail 1. After the movable pair 2 is assembled on the guide rail 1, the second ball 282 is utilized to abut against the top of the guide rail 1, thereby reducing the friction between the clamping assembly 26 and the top of the guide rail 1 and reducing wear during use, while also preventing the loosening of the clamping assembly 26 from causing the oil scraper 25 to detach.

[0036] In a specific implementation, the first ball 22 and the second ball 282 can adopt a uniform model, thereby reducing the number of parts during splicing and further improving splicing efficiency.

[0037] In one embodiment, a mounting groove for assembling the first ball 22 is provided on the slider 21, an oil guide hole connected to the mounting groove is provided at one end of the slider 21 close to the end cover 23, an oil guide groove connected to the oil guide hole after the end cover 23 and the slider 21 are spliced ​​is provided at one end of the end cover 23 close to the slider 21, and an oil filling hole is provided on the oil scraper 25 for connecting to the oil guide groove after the oil scraper 25 and the end cover 23 are spliced.

[0038] Such a design enables the latch 252 on the oil scraper blade 25 to not only be used for locking purposes, but also to serve as an oil filling channel, making it convenient for maintenance personnel to add oil from the outside.

[0039] In one embodiment, a sealing ring is provided between the end cover 23 and the slider 21 to prevent the lubricating oil in the oil guide groove from overflowing.

[0040] Such a design can not only prevent the lubricating oil from overflowing, but also allow the joint between the end cover 23 and the slider 21 to have a certain amount of expansion and contraction, thereby reducing the problem of being unable to join due to insufficient processing precision.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
