[0002] A linear guide rail is a core component of precision mechanical equipment. Its function is to support and guide moving components, and to perform reciprocating linear motion in a given direction and can bear a certain torque.

[0003] The application number is CN202220039082.0, which discloses a high-torque ball linear slide rail, including a linear guide rail, a slider, balls, a ball holder, a dust-proof steel sheet, an end cover and a sealing cover plate. The linear guide rail is provided with an upper ball groove and a lower ball groove. The center distance between the upper ball groove and the lower ball groove is 0.3-0.4 times the height of the linear guide rail. The width in the middle of the linear guide rail is 0.6-0.7 times the width of the top of the linear guide rail. The height of the groove is 0.3-0.4 times the height of the linear guide rail. By increasing the center distance between the upper ball groove and the lower ball groove, the overlapping area between the slider and the linear guide rail is increased, the overall combined height of the slider and the linear guide rail is reduced, the operating center of gravity is lowered, and the anti-torsional pendulum performance and anti-vibration performance of the linear guide rail are improved. On the other hand, the width and depth of the groove are deeper and wider than those of the traditional linear guide rail. This design makes the assembly of the slider and the linear guide rail more firm, and further improves the anti-torsional pendulum performance and anti-vibration performance of the linear guide rail.

[0004] The following defects exist in the ball linear slide rail disclosed in the above document: During the use of this slide rail, the slider is stably slid on the guide rail by the reciprocating rolling between the balls. When the internal balls pass through the guide rail that needs to turn, when the balls roll back and forth on this guide rail, over time, the balls may be affected by the guide rail and fall off. At this time, the balls in the slider need to be reinstalled and arranged, but the slider of this structure cannot be disassembled and can only be replaced as a whole.

[0005] It can be seen that the existing ball linear slide rail does not have the function of conveniently disassembling the slider to replace the balls, and it is necessary to improve the existing deficiencies to provide a function that can conveniently disassemble the slider to replace the balls.
