A kind of children's bicycle frame strength testing equipment

Abstract

The invention provides a frame strength testing device for children's bicycles, which includes a body shell, a working cavity is arranged in the body shell, and a first chute with symmetrical left and right positions and an upward opening is arranged on the bottom wall of the working cavity, and the first chute slides in the first chute. There is a first sliding block slidably connected with the working chamber, an adjustment component capable of driving the first sliding block to move and adjust the position is arranged in the bottom wall of the working chamber, a vibration chamber is arranged in the first sliding block, and a first sliding block is slidably arranged in the vibration chamber. A connecting block; the centrifugal block provided by the present invention can extend out of the centrifugal cavity to drive the first connecting rod to move under the driving of the second motor, and plays the role of adjusting the length of the centrifugal block extending out of the centrifugal cavity by adjusting the rotation speed of the rotating block , so as to adjust the stroke of the up and down vibration of the first connecting rod, and realize the function of steplessly adjusting the vibration frequency of the vibration frame.

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
