Abstract

The invention provides an armrest base for a cart. The armrest base comprises an armrest base member which is fixedly mounted on a bottom plate of the cart; the end of an armrest is rotatably connected to the armrest base member which comprises a first side plate and a second side plate; the first side plate and the second side plate are each in an L shape, the first side plate is provided with afirst bent end plate, and the second side plate is provided with a second bent end plate; and a notch is formed in the end face of the first bent end plate, a convex plate is arranged on the end faceof the second bent end plate, and the convex plate is clamped in the notch. The connecting mode of the two L-shaped side plates constituting the armrest base member is changed from welding to clamping, and the clamping position is fixed through a fixing part, so that the stability of the structure is guaranteed; and therefore, compared with the prior art, the mounting efficiency of the armrest base member is improved while the structural strength of the armrest base member is retained.

Description

technical field

[0001] The invention relates to the field of casters, in particular to an armrest base for carts. Background technique

[0002] Casters are a general term, including movable casters and fixed casters. Swivel casters are what we call universal wheels, and its structure allows 360-degree rotation; fixed casters are also called directional casters, which have no rotating structure and cannot be rotated. Usually, the two kinds of casters are used together. For example, the structure of the trolley is two directional wheels on the front, and two universal wheels near the push armrest on the back.

[0003] The armrest base used for the trolley is often formed by welding, which has low working efficiency and is prone to inaccurate positioning of welded parts. Contents of the invention

[0004] In view of this, the present invention changes the connection mode of the two L-shaped side plates that make up the armrest base member, from welding to clamping, and uses...
