Abstract
The utility model discloses a sliding self-locking lift pillar which comprises a control button, a spring, a clutch, a round pin, a sliding pole, a lift sleeve, a fixed sleeve, a rotating shaft and a skid-pin assembly, wherein the pillar comprises the fixed sleeve and the lift sleeve (both can not relatively rotate), the upper portion of the lift sleeve is provided with the fixed clutch, the lower portion thereof is provided with the skid-pin assembly which is blocked in the spiral flute of the rotating shaft. When the control button is pressed, the clutch is disengaged through the round pin, and then the rotating shaft arranged at the bottom of the fixed sleeve can freely rotate under the vertically sliding of the lift sleeve. When the control button is unclamped, the clutch is reset under the effect of the spring, at the same time the rotating shaft is locked by the lift sleeve through the sliding pole, and the skid-pin assembly arranged below the lower portion of the lift sleeve is blocked in the spiral flute of the rotating shaft and can not move downward, thereby achieving the effect of self-locking and load-bearing. The utility model has the advantages of compact and flexible structure, light weight, fast lift speed, convenient operation, reliable operation, large carrying capacity, beautiful appearance and extensive uses.
Description
Technical field
The utility model relates to a kind of plug-type self-locking lifting column, specially refers to a kind of plug-type self-locking lifting column of video display support equipment.
Technical background
At present traditional screw mandrel transmission, the distance between point of action is less, rigidity is relatively poor, easily the skidding of support tooth, dangerous, the support tooth is untimely, the more complicated that operates, noise is big, supporting power is little, and rising or falling speed is slow, give lifting for coming inconvenience, therefore, be necessary prior art is improved.
Summary of the invention
Main purpose of the present utility model is to overcome above-mentioned deficiency, and a kind of fast lifting that has is provided, and is easy and simple to handle, supporting power is big, a kind of plug-type self-locking lifting column in safe and reliable labour-saving.
The purpose of this utility model is achieved by the following technical solution:
A kind of plug-type self-locking lifting column, comprise: control button, spring, power-transfer clutch, round pin, litter, lifting sleeve, fixed sleeving, S. A., slide latch component, it is characterized in that: lifting sleeve (both can not relatively rotate) is housed in the described fixed sleeving, fixing power-transfer clutch is equipped with on lifting sleeve top, the sliding pin assembly is equipped with in the bottom, and the sliding pin assembly is stuck in the plug helix of S. A..
When pressing control button, by round pin power-transfer clutch is broken away from, the S. A. that is installed in the fixed sleeving bottom this moment can rotate freely in the push-and-pull up and down of lifting sleeve.
When decontroling control button, under the effect of spring, clutch reset, this moment, lifting sleeve pinned S. A. by litter, the sliding pin assembly of lifting sleeve bottom is stuck in the plug helix of S. A., can not move down again, thereby reach the effect of self-locking and load-bearing.
