[0026] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0027] Reference example Figures 1 to 6A linear guide slider with a silent effect comprises a slider 1, and a circulator 2 and a ball chain 3 arranged on both sides of the slider 1. First through holes 11 are arranged at the upper and lower parts of both sides of the slider 1, and first fitting parts 12 are arranged at the upper and lower parts of both sides of the inner wall of the slider 1. A first protrusion 13 is arranged between the first fitting parts 12. The circulator 2 is provided with a hollow retainer 21 and inserted into the first through hole 11. The hollow retainers 21 of the circulators 2 located on both sides of the slider 1 are plugged and connected to each other. The ball chain 3 is slidably arranged in the hollow retainer 21, and the ball chain 3 also resists Connected to the first fitting portion 12, the hollow retainer 21 is provided with an active groove 22 for the chain edge of the ball chain 3 to move, which is used to make the chain of the ball chain 3 tilt toward the first protrusion 13. By arranging the ball chain 3 in the hollow retainer 21, it is avoided that the ball chain 3 and the first through hole 11 rub against each other to generate noise. Through the active groove 22, the chain edge of the ball chain 3 is made to face the first protrusion 13, and the chain edge of the ball chain 3 is prevented from rubbing against the guide rail, thereby further reducing the generation of noise, and avoiding the friction between the chain edge and the guide rail, and avoiding the generation of iron filings;

[0028] It is worth mentioning that a rib 4 is provided between the circulators 2, the inner wall of the rib 4 fits the ball chain 3, and the rib 4 is provided with a second through hole 41 for the ball chain 3 to penetrate, and the second through hole 41 prevents the ball chain 3 from contacting the guide rail to generate friction and noise;

[0029] It is worth mentioning that the circulator 2 is provided with a guide plate 23, and protrusions 24 are provided on both sides of the guide plate 23. A gap is left between the protrusion 24 and the inner wall of the slider 1 for the chain edge of the ball chain 3 to move. A resistance part 25 is provided on one side of the protrusion 24 and fits the ball chain 3. The gap prevents the ball chain 3 from contacting with the guide rail to generate friction and noise. The resistance part 25 guides the ball chain 3 to move in an orderly manner.

[0030] It is worth mentioning that the ball chain 3 is composed of a steel ball retainer 31 and a ball 32. The steel ball retainer 31 is provided with a plurality of equally spaced bead holes 311. The ball 32 is arranged in the bead holes 311. The bead holes 311 are provided with fixing parts 312 on both sides. The fixing parts 312 are provided with second fitting parts 313 and fit the surface of the ball 32. The bead holes 311 accommodate the ball 32. The ball 32 is placed in the bead holes 311, so that the fixing parts 312 are squeezed by the ball 32 to open to both sides. After the ball 32 enters the fixing parts 312, the fixing parts 312 shrink, so that the second fitting parts 313 fit the ball 32 to prevent the ball 32 from falling off during the activity.

[0031] It is worth mentioning that the steel ball retainer 31 is set to be made of rubber material, and the circulator 2 is set to be made of plastic material. The two ends of the steel ball retainer 31 are provided with connecting parts 314, and are connected and fixed to each other. Since the steel ball retainer 31 is made of rubber material and the hollow retainer 21 is made of plastic material, the noise generated by the ball chain 3 during the activity is further reduced, and the rubber material has certain extensibility and buffering properties. When the ball chain 3 encounters interference or poor operation, the steel ball retainer 31 is stretched to avoid breakage. The connection and fixation can be connected by hot riveting, hot pressing, adhesion, etc.

[0032] It is worth mentioning that the hollow retaining frame 21 on one side of the circulator 2 is provided with a second protrusion 211, and the hollow retaining frame 21 on the other side of the circulator 2 is provided with a slot 212 for the second protrusion 211 to be inserted into. By inserting the second protrusion 211 into the slot 212, the hollow retaining frames 21 are connected and fixed to each other.

[0033] The above design scheme can enable the product to achieve the advantages of quiet effect and friction avoidance.

[0034] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
