The utility model aims to solve the defects in the prior art that the angle adjustment is performed by utilizing a gear mechanism, the stability of a backrest is poor when the backrest is loaded, and provides a trolley with the function of adjusting the angle of the backrest.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a shallow with but angle regulation function of back, includes the automobile body, its characterized in that, install support frame and back frame on the automobile body, install the stopper and the gag lever post of installing on the back frame that are used for adjusting back frame angle between support frame and the back frame on the support frame, fixedly connected with rotates the cover of connecting on the stopper on the back frame.

Preferably, the inner side wall of the limiting block is provided with at least one limiting groove, and the limiting rod is clamped in the limiting groove.

Preferably, the end face of one side of the limiting rod is arranged upwards in an arc-shaped inclined mode, and the shape of the part, clamped in the limiting groove, of the limiting rod is matched with the limiting rod.

Preferably, the angle between the backrest frame and the support frame is in the range of 135 ° -180 °.

Preferably, the limiting rod is slidably connected in the backrest frame, and a rebound member is mounted at one end of the limiting rod located in the backrest frame.

Preferably, the side section of the limiting block is concave.

Compared with the prior art, the utility model has the beneficial effects that:

the stability is stronger after the back rest frame is adjusted to be fixed at a good angle by utilizing the limiting block which is fixedly connected, so that the safety performance of the equipment can be effectively ensured.

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.

The terms such as "upper", "lower", "left", "right", "middle" and "a" and the like are also used herein for descriptive purposes only and are not intended to limit the scope of the utility model for which the utility model may be practiced or for which the relative relationship may be altered or modified without materially altering the technology.

Referring to fig. 1 to 4, a cart with backrest angle adjusting function comprises a cart body 1, a support frame 4 and a backrest frame 5 are installed on the cart body 1, a limiting block 3 which is used for adjusting the angle of the backrest frame 5 and is installed on the support frame 4 and a limiting rod 6 which is installed on the backrest frame 5 are installed between the support frame 4 and the backrest frame 5, the side section of the limiting block 3 is in a concave shape, a rotating sleeve 2 which is rotationally connected on the limiting block 3 is fixedly connected on the backrest frame 5, at least one limiting groove 7 is formed in the inner side wall of the limiting block 3, the limiting rod 6 is clamped in the limiting groove 7, the end face on one side of the limiting rod 6 is obliquely upwards arranged in an arc shape, the shape of the part of the limiting rod 6 clamped in the limiting groove 7 is matched with the limiting rod 6, and as the limiting block 3 is fixed on the side wall of the support frame 4 and belongs to non-rotating connection, and one side of the limiting groove 7 is in a plane, so that when the limiting block 3 is adjusted to a proper angle, even if the limiting block receives a large load, the limiting block 3 is stable, small rotation can not be performed, the stability when the safety is greatly increased.

In addition, as the other side of the limiting groove 7 is an arc-shaped surface, the limiting rod 6 does not need to be retracted by using a control handle when the folding device is folded, and the folding efficiency is higher.

The angle between the backrest frame 5 and the supporting frame 4 ranges from 135 degrees to 180 degrees, wherein when the limiting rod 6 falls in the other limiting groove 7, the angle of the backrest frame 5 is 110 degrees, and the back of a child is towed, so that the child can observe the surrounding environment from a close to a built-up view angle, and the comfort is improved.

The limiting rod 6 is slidably connected in the backrest frame 5, one end of the limiting rod 6, which is located in the backrest frame 5, is provided with a rebound member, the rebound member can be one of a spring, an elastic rope, a rubber rope and the like, the backrest frame 5 is provided with a control handle, the limiting rod 6 is controlled to slide in the backrest frame 5 by the handle, and the limiting rod is propped in the limiting groove 7 by the rebound member.

In the present utility model, the terms "mounted," "connected," "secured," and the like are to be construed broadly, unless otherwise specifically indicated and defined.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
