The utility model aims at solving the problem that the frame existing in the prior art is troublesome to level after the height is adjusted, and providing a height-adjustable frame base.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a but height-adjusting frame base, includes chassis and roof-rack, the upper portion of chassis is fixed with the guide bar, the downside of roof-rack is fixed with the lower extreme open-ended uide bushing corresponding with the guide bar, the top of guide bar is fixed with the spacing ring with uide bushing sliding fit, the upside normal running fit of chassis has vertical coarse adjusting screw rod, the upper end outside screw-thread fit of coarse adjusting screw rod has the sleeve, and the inboard screw-thread fit in telescopic upper end has the fine tuning screw rod, and the upper end and the roof-rack normal running fit of fine tuning screw rod.

Preferably, the bottom of the underframe is fixed with a support leg, and the bottom of the support leg is sleeved with a support leg sleeve.

Preferably, the top frame is provided with a through hole.

Preferably, a vertical scale bar is arranged on the guide rod.

Preferably, a ball groove is formed in the limiting ring, and balls tangent to the inner wall of the guide sleeve are placed in the ball groove.

Preferably, the lower end of the coarse adjustment screw rod and the upper end of the fine adjustment screw rod are respectively fixed with a thumb wheel.

The utility model has the advantages that:

1. the utility model discloses set up guide bar and uide bushing complex structure around the base, ball on the guide bar is tangent with the uide bushing inner wall, can keep the roof-rack not to rock at the in-process of height-adjusting.

2. The base can be roughly adjusted and then finely adjusted, and scales are arranged on the guide rod, so that the height of the base can be adjusted in a quantized mode.
