Special roller wheel shaft for child slide

Abstract

The invention discloses a special roller wheel shaft for a child slide. The special roller wheel shaft comprises a roller wheel shaft main body, wherein a first connecting rod is arranged on one end of the roller wheel shaft main body, a second connecting rod is arranged on the other end of the roller wheel shaft main body, one end of the inner portion of the roller wheel shaft main body is sleeved with a first bearing, and one end, close to the one side of the first bearing, of the inner portion of the roller wheel shaft main body is provided with a first limiting ring. When a worker installsthe roller wheel shaft of the special roller wheel shaft on the child slide, the first connecting rod can be pressed, therefore, the first connecting rod drives a first connecting ring and a second connecting ring to slide in the roller wheel shaft main body, a compression spring of the roller wheel shaft is forced to deform through extrusion of the first connecting ring, and a second limiting ring can perform limiting operation on the second connecting ring of the roller wheel shaft, the first limiting ring can be used for limiting the first connecting ring of the roller wheel shaft, and thefirst connecting rod can slide in a first bearing and a second bearing, and therefore, the roller wheel shaft of the special roller wheel shaft can be conveniently clamped into the child slide.

Description

technical field [0001] The invention relates to a roller shaft, in particular to a special roller shaft for children's slides. Background technique [0002] The unpowered roller is also called the roller table. There are two kinds of long roller table and short roller table. The surface shape of the rollers of the long roller table is cylindrical, conical and curved. The cylindrical long roller table is the most widely used. The roller conveyor is suitable for the transportation of various boxes, bags, pallets, etc., bulk materials, Small items or irregular items need to be transported on pallets or in turnover boxes. It can transport a single piece of heavy material, or withstand a large impact load, and the roller lines are easy to connect and filter. Multiple roller lines and other conveyors or special planes can be used to form a complex logistics delivery system to complete various process needs. . The roller conveyor has the advantages of simple structure, high rel...

Problems solved by technology

[0003] However, the existing rollers for children's slides cannot be installed well, and when there is a slight deviation between the inner distance dimension of the children's slide and the overall size of the roller shaft, the roller shaft cannot be well clamped and limited
