Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic valve detection for motor vehicles, and in particular relates to a wiring assembly for an electromagnetic valve test bench. Background Art

[0002] The solenoid valve test bench is a device used to test and detect the performance of solenoid valves. The solenoid valves are tested by simulating real working conditions to ensure their normal operation and safety and reliability. The EMU refers to the high-speed EMU, which is a high-speed train used for railway transportation. In the EMU, solenoid valves are widely used to control the braking, traction and steering systems of the train, playing a key role. There is a certain relationship between the solenoid valve test bench and the EMU.

[0003] The wiring assembly of the solenoid valve test bench is an important component for connecting the solenoid valve and the control system. It is responsible for transmitting the signal of the solenoid valve to the control system and the signal of the control system to the solenoid valve. When installing and connecting the wiring assembly of the solenoid valve test bench, in order to ensure the correctness of the wiring and the normality of the signal transmission, when the wiring needs to be detected, the wiring can be detected by an oscilloscope. The oscilloscope can be used to detect the signal waveform between the solenoid valve and the control system to ensure the accuracy and stability of the signal transmission. The signal frequency and amplitude in the solenoid valve and the control system can be measured to help confirm whether the signal parameters meet the requirements, etc. When using an oscilloscope, it is often placed on the ground or on the solenoid valve test bench, and there is no component for clamping and fixing the oscilloscope. This makes it easy for the oscilloscope to shake after being hit, and it is easy to fall and collide with the ground, thereby damaging the components inside the oscilloscope. The solenoid valve test bench cannot clamp and fix the oscilloscope. The problem with the above technology is that when the wiring of the solenoid valve test bench needs to be detected by an oscilloscope, the oscilloscope cannot be clamped and fixed, making the oscilloscope easy to be hit and fall and hit the ground.

[0027] The working principle of this utility model:

[0028] When it is necessary to take out the oscilloscope 2b, the movable block 801 is pushed to the left by manpower to move the two connecting rods 703 to the left. During the movement of the two connecting rods 703 to the left, the left sides of the two connecting rods 703 will rotate toward the opposite end, thereby causing the two positioning blocks 701 to move toward the opposite end and move out from the inside of the two fixed blocks 4. At this time, the movable block 5 can drive the blocking block 302, the two clamping blocks 301, the first clamping block 303 and the second clamping block 304 to move to the left, so that the clamping assembly 3 is out of contact with the oscilloscope 2b. When the movable block 5 moves to the leftmost position, the movement of the movable block 801 will cause The extrusion spring 802 is deformed, and the movable block 801 is released. Under the elastic action of the extrusion spring 802, the movable block 801 drives the two connecting rods 703 to rebound to their original position. The movement of the two positioning blocks 701 causes the reset spring 702 to be deformed. When the movable block 801 is released, the two positioning blocks 701 are rebounded to the inside of the two fixed blocks 4 under the elastic action of the reset spring 702, so that the movable block 5 is fixed to the two fixed blocks 4, which is convenient for the oscilloscope 2b. After the oscilloscope 2b is clamped and fixed by the clamping assembly 3, the oscilloscope 2b can be operated to detect the wiring of the solenoid valve test bench 1.
