Abstract

The utility model relates to a roof supporting rod for children carts. The utility model is characterized in that the outer surface of the rod body (2) is provided with at least one convex rib (1) which extends along the axial direction; the center of the rod body (2) is provided with a penetrating circular hole inner cavity (3) which extends along the axial extension; the other part of the surface ourside the rod body except for the surface of the rod body (2) provided with the convex rib (1) is a cylindrical surface of which the axle center and the axle center of the circular hole inner cavity (3) are coaxial. Because the rod body is provided with the circular hole inner cavity, therefore, material can be saved, the elasticity of the rod body is increased, the convex rib likewise plays a function for increasing elasticity and resisting being bended and folded, the utility model can not be easily broken in the process of being used.

Description

The ceiling strut bar of children trolley

The utility model relates to a kind of ceiling strut bar of children trolley.

In the prior art, top, the seat of children trolley generally all is provided with ceiling, and this ceiling is used to keep out the wind, sunshade, and ceiling is to make with cloth, and ceiling is provided with 3 to 4 curved strut bars across the both sides vehicle frame, and described strut bar is tightened described ceiling cloth.Because strut bar is bending, therefore require the ceiling strut bar to have elasticity and intensity preferably.But strut bar of the prior art is the cylindrical plastic pole, can fracture when bending is used.

The purpose of this utility model is to provide a kind of elasticity ceiling strut bar of children trolley preferably.

The technical solution of the utility model is: a kind of ceiling strut bar of children trolley, the outside face of the described body of rod are provided with a convex tendon that extends vertically at least, and the central authorities of the described body of rod have axially extended circular hole inner chamber.

The utility model compared with prior art has following advantage:

Owing to have the circular hole inner chamber on the body of rod, therefore can saving in material, and make the elasticity of the body of rod increase, set convex tendon plays the effect that increases elasticity, bend resistance too, makes the utility model easy fracture not in use.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is an outward appearance front view of the present utility model;

Accompanying drawing 2 is the A-A direction cutaway view of accompanying drawing 1; Wherein:

[1], convex tendon; [2], the body of rod; [3], circular hole inner chamber.

Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, a kind of ceiling strut bar of children trolley, the outside face of the described body of rod [2] is provided with a convex tendon [1] that extends vertically at least, convex tendon described in the accompanying drawing [1] has three, spacing distance between each convex tendon [1] equates that the central authorities of the described body of rod [2] have the axially extended circular hole inner chamber [3] that penetrates mutually.On the described body of rod [2], except that described convex tendon [1], the outside face of remaining body of rod [2] is a periphery, and the axle center of its cylindrical outer surface is coaxial with the axle center of circular hole inner chamber [3].

Claims

1, a kind of ceiling strut bar of children trolley is characterized in that: the outside face of the described body of rod [2] is provided with a convex tendon [1] that extends vertically at least, and the central authorities of the described body of rod [2] have the axially extended circular hole inner chamber [3] that penetrates.

2, the ceiling strut bar of children trolley according to claim 1 is characterized in that: described convex tendon [1] has three, and the spacing distance between each convex tendon [1] equates.

3, the ceiling strut bar of children trolley according to claim 1 is characterized in that: the body of rod outside face outside the convex tendon [1] on the described body of rod [2] is a periphery, and the axle center of its cylindrical outer surface is coaxial with the axle center of circular hole inner chamber [3].
