Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of slide rail mechanisms, in particular to a built-in sliding device. Background Art
[0002] Linear slides, also known as linear guides, are a motion system consisting of a linear track and a slider for reciprocating linear motion in a given direction. They can be categorized by structure as roller-type linear slides, cylindrical linear slides, and ball-type linear slides. They are widely used in industrial automation, aerospace, new energy, intelligent logistics, rail transportation, medical equipment, furniture, and other industries.
[0003] Conventional roller-type sliders use eccentric wheels for adjustment. This is difficult to operate, has poor adjustment accuracy, low force, and easily damaged threads. Micro-adjustments fail to achieve the desired result. During micro-adjustments, we discovered that due to the already formed fixed conical indentation, even slight offset adjustments would cause the slider to slide back into the center of the indentation, defeating the purpose of adjustment. Therefore, we developed a new sliding mechanism. Utility Model Content

[0029] Conventional roller-type sliders in the prior art use an eccentric wheel for adjustment. This is difficult to operate, has poor adjustment accuracy, low force, and easily damaged threads. Micro-adjustments fail to achieve the desired effect. During micro-adjustments, it was discovered that due to the already formed fixed conical recess, even a slight offset adjustment would cause the slider to continue sliding into the center of the recess, defeating the purpose of adjustment.
[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a built-in sliding device. When it needs to be used, only a top screw 28, a T-shaped fixing nut 26 and a bearing screw 24 need to be added to move and doubly fix the bearing 23.
[0031] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:
[0032] Combine Figure 1-Figure 4 , an embodiment of the present application provides a built-in sliding device, including a slide rail assembly 1; the slide rail assembly 1 includes: a slide groove 12 is opened at the top of the guide rail 11; a slider assembly 2 is arranged on the slide rail assembly 1, and the slider assembly 2 includes: a slider 21 is arranged at the top of the guide rail 11; a second bearing 23 is arranged at the bottom of the slider 21; a bearing screw 24 passes through the second bearing 23; a step hole 25 is opened at the top of the slider 21; a fixing nut 26 is arranged inside the step hole 25, and is threadedly connected to the bearing screw 24.
[0033] During use, the slider 21 slides freely in the slide groove 12 of the guide rail 11 through the bearing 23 at the bottom. Loosen the bearing screw 24, adjust and fix the position of the fixing nut 26 of the bearing screw 24, so that the bearing 23 fits the slide groove 12 more closely to increase the friction, and then tighten the bearing screw 24 to fix it, thereby increasing the tension of the slider 21 on the guide rail 11. The bearing 23 used for sliding of the slider assembly 2 is built into the slide groove 12 of the guide rail 11.
[0034] Specifically, the fixing nut 26 is a T-nut.
[0035] In some embodiments, a screw hole 27 is formed on the outer wall of the slider 21. A top screw 28 is threadedly connected to the inner surface of the screw hole 27 and engages with the fixing nut 26. After loosening the bearing screw 24, the top screw 28 in the screw hole 27 is rotated to move the second bearing 23 outward, pressing against the slide groove 12 to increase resistance. The bearing screw 24 is then tightened to achieve double fixation.
[0036] In some embodiments, a bearing 1 22 is provided at the bottom of the slider 21, and the bearing 1 22 is connected to the slider 21 via a bearing 2 23. The bearing 1 22 and the bearing 2 23 are used in conjunction with each other, and the bearing 1 22 is fixed and is moved to press the bearing 2 23 and the bearing 1 22 against the slide 12.
[0037] In some embodiments, the first bearing 22 and the second bearing 23 are staggered. The staggered arrangement of the first bearing 22 and the second bearing 23 can increase the overall stability of the slider assembly 2.
[0038] In some embodiments, a gasket 241 is provided between the first bearing 22 and the second bearing 23 and the slider 21. The gasket 241 enhances the fixing effect of the first bearing 22 and the second bearing 23.
[0039] In some embodiments, a mounting hole 211 is provided on the top of the slider 21. The mounting hole 211 is provided to facilitate connection and fixation of the slider 21 with other external structures.
[0040] In some embodiments, the inner wall of the slide groove 12 is provided with an optical axis 13 that cooperates with the bearing 1 22 and the bearing 2 23. The optical axis 13 cooperates with the bearing 1 22 and the bearing 2 23 to prevent the slider assembly 2 and the slide rail assembly 1 from separating from each other, and can only be separated from both ends.
[0041] In some embodiments, the first bearing 22 and the second bearing 23 are V-shaped bearings. The V-shaped bearings enable the first bearing 22 and the second bearing 23 to make point-to-point contact with the optical axis 13, thereby reducing sliding friction.
[0042] In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.
[0043] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
