Description

Technical Field

[0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell pressure-maintaining test bench. Background Art

[0002] A fuel cell is a power generation device that converts the chemical energy in fuel and oxidant directly into electrical energy. When the fuel and air are fed into the fuel cell respectively, electricity is miraculously produced. From the outside, it has positive and negative electrodes and electrolytes, like a battery, but in fact it cannot store electricity but is a power plant. With the explosive development of fuel cells, fuel cells are widely used in the vehicle industry, and the demand for fuel cells continues to increase. The airtightness of the fuel cell itself in production has a great influence on the performance of the fuel cell. Therefore, in the production process of the fuel cell, the fuel cell needs to be pressure tested to ensure the safety of the fuel cell. In the pressure test process, a test bench is usually used to place and store the fuel cell and the pressure test device.

[0003] Existing fuel cells are tested before use, and most of the pressure test racks used for fuel cells are not equipped with a fixing mechanism when testing the fuel cell. When a worker accidentally slips and touches the fuel cell around the pressure test rack, the fuel cell without a fixing mechanism may slide off the pressure test rack, causing damage to the fuel cell, thereby reducing the service life of the fuel cell. In addition, the existing fuel cell test rack is not easy to move. Summary of the invention

[0017] Beneficial effects:

[0018] 1. The fuel cell pressure-maintaining test bench, by rotating the first rotating column, the first rotating column will drive the second rotating column to rotate through the first driving gear and the first driven gear, and the second rotating column will drive the second threaded column to rotate, and the second threaded column will drive the first moving block to move in the connecting through hole through the first fixed column, and the fuel cell is clamped and fixed by the clamping plate driven by the first moving block, so as to ensure that the fuel cell is located on the workbench and is in a fixed state, and prevent the fuel cell from displacement.

[0019] 2.

The telescopic column will extend, and the moving wheel will not move upward due to its own gravity. The base plate will rise, and the supporting bottom column will lose contact with the ground, so that the overall structure will move through the moving wheels. BRIEF DESCRIPTION OF THE DRAWINGS
