Auxiliary lifting device for lifting tea table

Abstract

The invention discloses an auxiliary lifting device for a lifting tea table. The auxiliary lifting device comprises a control wheel, a chute and a sliding body in the chute, wherein a locking body is positioned in the middle of two sliding racks in the chute, and the middle part of the locking body is provided with a locking hole running from top to bottom; the bottom of the front end of a locking rod is an inclined plane; a locking tooth is positioned in the locking hole and hinged with the locking body, and the other end of the locking tooth is provided with an inclined plane and a sharp tooth; the inclined plane is attached to the inclined plane at the front end of the locking rod; the bottom of the sharp tooth is provided with a spring; pinions in two pairs of gears are mutually meshed, and two gearwheels are meshed with the two sliding racks respectively; and the sharp tooth on the locking tooth is embedded in a tooth space of a pinion. The auxiliary lifting device can ensure quick sliding of the sliding body and also can control quick positioning of sliding positions because a ratchet structure is formed by matching the locking tooth, the locking rod and a gear set. When thetable top of the tea table is lifted, the table top is uplifted to a required height; and when the table top of the tea table is descended, the locking rod is pushed, the table top is pressed downwards to the required height and the locking rod is pulled out.

Description

technical field [0001] The invention relates to a coffee table, in particular to a lifting auxiliary device for lifting the coffee table. Background technique [0002] Common tea tables are of fixed height. In order to expand the scope of use of the tea table and meet the needs of people of different ages or heights, or to use the tea table as a dining table, desk, workbench, etc., it is often necessary to adjust the height of several sides of the tea table. The lifting parts of the common lifting coffee table now adopt the structure of four legs as casings. The inner and outer casings slide up and down relatively. The purpose of adjusting the surface height. The other is to adopt the hinged leg structure, through which two sets of crossed legs are hinged on one axis, the hinge angle is adjusted, and then the two sets of legs are locked to achieve the purpose of lifting height. Also have a kind of Chinese patent with the similar structure of the present invention, and the ...

Problems solved by technology

However, this patent achieves the purpose of finally adjusting the height of the legs by rotating the screw nut and the screw mandrel, so the height cannot be adjusted quickly

At the same time, due to the lack of a non-return mechanism, it is not easy to lock the height of several sides, and the reliability is not high
