Child bicycle frame strength detection equipment

Abstract

The child bicycle frame strength detection equipment comprises a machine body shell, a working cavity is formed in the machine body shell, the bottom wall of the working cavity is provided with first sliding grooves which are symmetrical in the left-right direction and provided with upward openings, and first sliding blocks slidably connected with the working cavity are slidably arranged in the first sliding grooves; an adjusting assembly capable of driving the first sliding block to move and adjust the position is arranged in the bottom wall of the working cavity, a vibration cavity is formed in the first sliding block, and a first connecting block is slidably arranged in the vibration cavity. The centrifugal block can extend out of the centrifugal cavity under the driving of the second motor to drive the first connecting rod to move, and the function of adjusting the length of the centrifugal block extending out of the centrifugal cavity by adjusting the rotating speed of the rotating block is achieved, so that the stroke of vertical vibration of the first connecting rod is adjusted, and the function of stepless adjustment of the vibration frequency of the vibration frame is achieved.

Description

technical field [0001] The invention relates to the technical field of frame strength detection, in particular to a frame strength detection device of a children's bicycle. Background technique [0002] Bicycle is a common means of transportation in daily life, and the frame is an important part of the bicycle. Its structure is welded by a plurality of frame bodies. In order to ensure the safety of the frame during use, the welding is completed on the frame. After that, the strength of the frame needs to be tested. [0003] The detection functions of the frame detection devices in the prior art are relatively simple, and the children's bicycles have various sizes in order to adapt to the riding needs of children of different ages, such as the detection device in the patent CN202022683749.4 , it can only detect bicycles of a fixed size, and cannot adapt to bicycles of different sizes, and must be equipped with tires for detection, which wastes detection time and intensity, a...

Problems solved by technology

[0003] The detection function of the frame detection device in the prior art is relatively simple, and in order to meet the riding needs of children of different age groups, the size of the children's bicycle is variable, such as the detection device in the patent CN202022683749.4 , it can only detect bicycles of fixed size, and cannot adapt to bicycles of different sizes, and must be installed with tires for detection, which wastes detection time and intensity, and the vibration intensity of detection is also fixed, and it is impossible to simulate vibration intensities of different intensities
