[0019] The present invention will be further described below in conjunction with the accompanying drawings: Refer to the attached Figures 1 to 9As shown: A linear slider device for roller guide sleeve guidance, comprising: a slider body 1 having inner raceway holes 100 for roller movement on the left and right sides, a pair of retainers 2 respectively connected to the left and right sides of the slider body 1, and two end covers 3 respectively fixed to the two end surfaces of the slider body, two inner raceway holes 100 are provided on each side of the slider body 1, and the two inner raceway holes 100 on the same side are arranged in parallel up and down along the height of the slider body 1, wherein both ends of the retainer 2 are provided with positioning frames 200 abutting against the end of the slider body 1, and the positioning frames 20 0 is provided with two inner circulation through holes 201 matching the inner raceway holes 100, an inner circulation raceway portion 202 is provided at the outer end of the positioning frame 200, the inner circulation raceway portion 202 is communicated with one of the inner circulation through holes 201, and the inner circulation raceway portions 202 on both sides of the retaining frame 2 are arranged in opposite directions and staggered; two auxiliary strips 10 are inserted in each inner raceway hole 100, which are fitted with each other and form the inner raceway 101 in the middle part thereof, and the inner raceway 101 is used to guide the flexible guide sleeve 11 equipped with rollers to move in the inner raceway 101 along the length direction of the slider body 1.

[0020] The slider body 1 is the core part of the whole device. The inner raceway holes 100 for roller movement are respectively arranged on the left and right sides of the slider body 1. There are two inner raceway holes 100 on each side, and the two inner raceway holes 100 on the same side are arranged in parallel up and down along the height of the slider body 1. This double-layer raceway design increases the bearing capacity and stability of the slider. A pair of retainers 2 are respectively connected to the left and right sides of the slider body 1 to support and fix the rollers and ensure their smooth operation in the inner raceway 101. Both ends of the retainer 2 are provided with a The positioning frame 200 is used to ensure the precise positioning between the retaining frame 2 and the slider body 1 and provide necessary support. The positioning frame 200 is provided with two inner circulation through holes 201 matching the inner raceway holes 100. These through holes allow the rollers to circulate in the inner raceway 101. In this embodiment, an inner circulation raceway portion 202 is provided at the outer end of the positioning frame 200. The inner circulation raceway portion 202 is connected to one of the inner circulation through holes 201 to form a complete raceway circulation path. The inner circulation raceway portions 202 are staggered in opposite directions. This design allows the rollers to circulate smoothly in different directions, thereby improving the overall movement efficiency and stability. Each inner raceway hole 100 is provided with two auxiliary strips 10 that fit each other and form an inner raceway 101 at the middle portion thereof.

The inner raceway 101 is used to guide the flexible guide sleeve 11 on which the rollers are installed to move in the inner raceway 101 along the length direction of the slider body 1. The design of the flexible guide sleeve 11 increases the flexibility and adaptability of the rollers, thereby enabling them to better cope with various working conditions. The two end covers 3 are respectively fixed to the two end surfaces of the slider body 1, and are used to close the two ends of the slider body 1, protect the internal structure and prevent dust and other impurities from entering. The design of the end cover 3 also includes a detachable inner circulation end cover 300 for the flexible guide sleeve 11 to circulate and rotate. The detachable setting facilitates maintenance and replacement, while ensuring the sealing and reliability of the entire device.

[0021] It is worth mentioning that an oil circuit system is provided inside the end cover 3 to facilitate lubrication of the rollers in the inner raceway.

[0022] Preferably, if Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, an inner slide groove 102 is opened on the auxiliary strip 10 along its length direction end, and the inner slide grooves 102 of the two auxiliary strips 10 face the same direction.

The shape and size of the guide portions 105 are precisely designed to ensure that when the two auxiliary strips 10 are fitted together, the two guide portions 105 on the same side can be perfectly aligned to form a continuous guide groove 103. This design not only provides additional lateral support for the flexible guide sleeve 11, but also ensures its precise positioning and stable movement in the inner raceway 101.

The design of the inner circulation end cover 300 ensures that it can fit tightly against the end face of the slider body 1 and cooperate with the inner slide groove 102 and the inner circulation raceway portion 202. The main function of the inner circulation end cover 300 is to provide a closed and continuous circulation path for the flexible guide sleeve 11, so that the flexible guide sleeve 11 can circulate smoothly between the inner circulation end cover 300, the inner slide groove 102 and the inner circulation raceway portion 202.
