Description

Adjustable balance movable universal castor for pipe support tabletop

Technical Field

The utility model relates to the technical field of movable universal casters of tube support tabletop feet, in particular to a balance-adjustable movable universal caster of a tube support tabletop.

Background

At present, the mahjong machine, dining table and other tools supported by feet have the problems of immovable, movable and poor balance. Firstly, the movable casters at the bottom are not installed, so that the movable casters are inconvenient to move; secondly, the movable casters are arranged, and the problem that the casters are difficult to fix and the tabletop is unstable exists; thirdly, for the supporting leg taking the mahjong machine as a main body, the existing castor needs to cut the leg pipe so as to keep the normal height of the tabletop.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides the balance-adjustable movable universal castor for the pipe support table top, which solves the problem that the existing universal castor can move under the condition that the height of a support pipe is not required to be changed; on the basis of moving, solve the fixed and balanced problem.

In order to achieve the above purpose, the utility model is realized by the following technical scheme: the ball support is provided with balls, the bottom of the inner side of the screw plug is provided with a concave chute which is matched with the upper half part of the ball support, the top of the universal rotary support is provided with a cross-shaped fixed slot which is matched with a jack at the top of the screw plug, and the ball support is clamped in the middle.

Preferably, the screw plug is provided with a circular groove.

Preferably, the screw plug is provided with a square groove.

Preferably, the concave sliding groove is arranged on the universal rotary support and is matched with the lower half part of the ball support.

Preferably, the bottom of the universal rotary support is provided with a roller.

Preferably, the screw plug is connected with a balance nut in a threaded manner.

The utility model provides a movable universal castor capable of adjusting balance of a tube supporting tabletop. The beneficial effects are as follows: the balance nut is rotated upwards, so that the roller contacts the ground to realize the moving function: the balance nut is rotated downwards, so that the roller leaves the ground to realize immovable.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-7, the present utility model provides a technical solution: the utility model provides a but balanced movable universal castor of pipe support desktop, includes screw stopper 1, ball support 2, universal swivel mount 3, is equipped with the ball in the ball support 2, and there is concave spout in screw stopper 1 inboard bottom to agree with ball support 2 upper half mutually, and universal swivel mount 3 top has the fixed slot of cross flower type, agrees with screw stopper 1 top jack, presss from both sides ball support 2 in the middle.

As a preferable technical scheme, the screw plug 1 is further provided with a circular groove for connecting with the circular table leg 6.

As a preferable technical scheme, the screw plug 1 is further provided with a square groove for connecting with the square table leg 7.

As a preferable technical scheme, the concave sliding groove is arranged on the universal rotary bracket 3 and is matched with the lower half part of the ball bracket 2.

As a preferred solution, the bottom of the universal swivel bracket 3 is further provided with a roller 4.

As a preferred technical solution, further, the screw plug 1 is screwed with a balancing nut 5.

It should be noted that: the 4 universal casters of the patent are arranged at the bottoms of the 4 round table legs 6, and when the universal casters move, the balance nuts 5 are rotated upwards to enable the casters 4 to contact the ground; the balancing nuts 5 are rotated downwards to be closely attached to the ground after being carried to a destination, and the heights of the 4 balancing nuts 5 are adjusted to enable the tabletop to be horizontal (the square table legs 7 are used in a similar manner).
