Technical Field

[0001] The utility model relates to the technical field of ball bushings, in particular to a positioning structure of a slide rail ball bushing. Background Art

[0002] In the design of modern furniture and industrial equipment, ball bearing slide systems play a vital role. They are widely used in drawers, wardrobes, server cabinets and other facilities to achieve smooth and stable pulling and pulling operations. Ball bearing slides reduce friction during sliding by built-in steel balls. These steel balls roll in the track, providing continuous and uniform support, making the pulling and pulling action smoother and silent.

[0003] Although existing ball bearing slide technology is very effective in providing smooth operation, there are still some technical challenges in its installation and maintenance process. Traditionally, ball bearing slides are usually fixed directly to the outer wall of the cabinet or furniture by bolts; this fixing method requires precise positioning and drilling of the outer wall of the cabinet before installation, which not only increases the complexity of installation, but also may cause inaccurate positioning, affecting the stability of the overall structure and the performance of the slide. In addition, when the slide needs to be maintained or replaced, the removal of the fixing bolts may become complicated and time-consuming.

[0004] In view of this, it is indeed necessary to provide a technical solution to the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning structure for a slide rail ball bushing in response to the deficiencies in the prior art, thereby solving the problem that the ball slide rail is fixed to the outer wall of a box body by bolts, but during installation, it is necessary to position it on the outer wall of the box body in advance, which makes it inconvenient during installation and has certain defects during replacement and maintenance.

[0007] A positioning structure of a slide rail ball bushing comprises a bearing shell, a bushing is installed on the inner wall of the bearing shell, a movable rail is installed on the inner wall of the bushing, and a clamping block is fixedly connected to one end of the outer wall of the bushing;

[0008] The outer wall of the bushing is provided with a plug hole, the inner wall of the plug hole is plugged with an insert block, one end of the insert block extends to the outer wall of the bearing shell and is fixedly connected to a limiting plate, the outer wall of the limiting plate is movably connected to a mounting shell, and the bottom of the mounting shell is fixedly connected to the outer wall of the bearing shell.

[0009] Preferably, a spring is pressed against the top of the inner wall of the mounting shell, and the bottom of the spring is pressed against the top of the limiting plate.

[0011] Preferably, a slideway is provided on the outer wall of the movable rail, a slider is slidably connected to the inner wall of the slideway, and the outer wall of the slider is fixedly connected to the outer wall of the bushing.

[0012] Preferably, a pull rod is fixedly connected to the top of the limiting plate, an outer wall of the pull rod is inserted into the inner wall of the spring, and the outer wall of the pull rod is movably connected to the inner wall of the mounting shell.
