Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifts, in particular to a slider device of a double-column lift. Background Art
[0002] A two-post lift is mainly used to lift a car to a certain height. The specific usage process is as follows: the operator rotates the support arm of the two-post lift and extends it under the car so that the lifting end of the support arm is aligned with the lifting point of the car. Then, the lift is operated to make the slide slide upward along the column, driving the support arm to move upward at the same time, thereby lifting the car.
[0003] The existing sliders are generally connected to the slots of the slide. The disadvantage is that a large number of sliders are used and the contact area with the slots of the slide is small. This will cause the sliders to be subjected to large forces, resulting in excessive and rapid wear of the sliders, which in turn affects the stability of the lifting equipment. For this reason, we propose a slider device for a two-post lift. Utility Model Content
[0004] In order to solve the problem that the existing slider is generally connected to the slot of the slide, which has the disadvantages of a large number of sliders used and a small contact area with the slot of the slide, which will cause the slider to be subjected to large force, resulting in excessive and rapid wear of the slider, thereby affecting the stability of the lifting equipment, the utility model provides the following technical solutions: a slider device of a two-column lift, comprising a lift slide, the lift slide being arranged in a lift column, and also comprising a slider and an axle pin, one end of the axle pin being fixedly connected to the lift slide, and the other end being rotatably connected to the slider, the slider being rotatably connected to the outer wall of the lift slide by the axle pin, and the slider being slidably connected to the inner wall of the lift column.
[0005] Preferably, a fixed shaft is provided at the lower end of the shaft pin, and a fixed shaft hole matching the fixed shaft is opened on the side wall of the lift slide body, and the fixed shaft can be fixedly connected in the fixed shaft hole.
[0006] Preferably, a retaining ring groove is provided on the lower end of the fixed shaft along the circumferential ring, and a retaining ring is installed in the retaining ring groove.
[0007] Preferably, a movable shaft is provided at the upper end of the shaft pin, and a movable shaft hole matching the movable shaft is opened at the center of the slider, and the movable shaft can be rotatably connected in the movable shaft hole.
[0008] Preferably, the movable shaft is provided with a shaft pin cover on its circumferential ring, and a recessed groove is provided on the movable shaft hole, and the shaft pin cover is rotatably connected in the recessed groove.
[0009] Preferably, the slider is made of an integrally formed polytetrafluoroethylene material.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] The utility model provides a slider device for a two-column lift, which avoids the disadvantages of using a large number of sliders, a small area, and a large force on the sliders. The entire surface of the slider is in contact with the inner wall of the lift, which increases the contact area, reduces the pressure on the slider, and greatly reduces the wear of the slider. Since the connection method of the slider is changed, maintenance and installation are simple. The slider structure is not fixed on the axle pin, forming a follow-up form, so that the entire surface of the slider can always contact the inner wall of the lift column as the slide tilts, and can bear the instability caused by the tilt of the slide, making the lifting process more stable.
