[0002] The main function of the rectangular slider is that it can provide stable and precise linear motion. It can be used as a mechanical element for pushing, pulling or positioning. By coordinating with other mechanical components, it can achieve various complex mechanical movements. In mechanical devices, sliders are often used to transmit power, control the direction of movement or fix positions to ensure the accuracy and stability of mechanical movement. Rectangular sliders are widely used in different scenarios.

[0003] The existing rectangular slider is usually composed of the following main parts: slider body, slide rail, steel ball, etc. The working principle is: convert the input mechanical energy into sliding kinetic energy. During the sliding process, the grooves or protrusions of the slider body are engaged with the corresponding parts of the slide rail, and the steel ball contacts the slide rail to ensure that the slider can slide stably on the slide rail.

[0004] The rectangular slider in the current prior art has the following disadvantages: the top of the slider is usually equipped with different accessories according to the working requirements, and some accessories are heavier, and the contact between the slider and the slide rail is the contact between the steel ball and the slide rail. The steel ball bears gravity, and the gravity of the heavier accessories is applied to the steel ball. Over time, the steel ball wears more, causing the slider to slide unsmoothly, seriously affecting its use; therefore, a rectangular slider is proposed to address the above problems.

Limiting strips are fixedly provided on both side walls of the slide rail, and the limiting strips are of V-shaped structure. The V-shaped groove of the roller contacts and cooperates with the V-shaped structure of the limiting strip. A rack is fixedly provided on the circumferential surface of one end of the movable rod, and linkage mechanisms are fixedly provided on both sides of the slider. Through the cooperation between the above structures, the roller and the limiting strip can share the gravity for the steel ball, so as to prevent the sliding of the slider from being stuck due to the accelerated wear of the steel ball due to the excessive gravity of the accessories.

[0007] Preferably, the linkage mechanism includes two groups of mounting ears fixedly arranged on the side surfaces of the slider, a rotating shaft is rotatably arranged between the mounting ears via bearings, first gears are fixedly arranged on the circumferential surfaces at both ends of the rotating shaft, the teeth of the first gear mesh with the teeth of the rack, a toothed plate is fixedly arranged on one side of the connecting plate, a second gear is fixedly arranged on the circumferential surface of the rotating shaft close to the toothed plate, the second gear meshes with the teeth of the toothed plate, and the linkage mechanism can be cooperated to make the roller fit the limit bar when the accessory is assembled, and the slider can be limited to prevent its angle deviation and jamming.

When the slider moves on the slide rail, the roller rolls on the limit bar, which shares the gravity for the steel ball, reduces the wear and tear and increases the service life. At the same time, it can also prevent the slider from angular deviation causing sliding jamming and affecting the use of equipment. BRIEF DESCRIPTION OF THE DRAWINGS
