[0005] Furthermore, the clamping device also includes a bracket fixed in the workbench, a cylinder fixed at the upper end of the bracket and extending up and down, a lifting plate is fixed at the end of the piston rod at the lower end of the cylinder, and the pressing platform is fixed at the bottom of the lifting plate.

[0006] Furthermore, the placement table has a first placement groove and a second placement groove distributed on the left and right, the hose is inserted into the first placement groove and the second placement groove, the upper ends of the first placement groove and the second placement groove are both open, the first pressing block extends into the first placement groove, and the second pressing block extends into the second placement groove.

[0007] Furthermore, the lower end surfaces of the first pressing block and the second pressing block are both arc-shaped concave surfaces for contacting the outer wall surface of the hose.

[0008] The application of the hose pressure cycle test bench provided by the utility model has the beneficial effect that the hose can be placed on the placement table, and the pressure table will press the hose after moving downward. The hose is pressed during the inflation and deflation cycle test and is not prone to movement or falling. After the test, the pressure table moves upward and the hose can be removed.

DETAILED DESCRIPTION

[0012] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0013] like Figure 1 , Figure 2 As shown, the hose pressure cycle test bench includes a frame 1, an air pump 2 is installed in the lower end of the frame 1, a display panel 3 is installed in the upper end of the frame 1, a workbench 4 is provided in the middle of the frame 1, three left and right distributed clamping devices 5 are fixed in the front end of the workbench 4, and the clamping device 5 includes a placement table 51 for placing the hose 6 and a liftable pressing table 52, the pressing table 52 is located above the placement table 51 and is used to press the hose 6 on the placement table 51, and the left and right ends of the bottom of the pressing table 52 are respectively provided with a first pressing block 521 and a second pressing block 522. The air pump 2 is connected to a pipe opening of the hose 6 through a pipe.

[0014] like Figure 2 As shown, the pressing device 5 also includes a bracket 53 fixed in the workbench 4, a cylinder 54 fixed at the upper end of the bracket 53 and extending up and down, a lifting plate 55 is fixed at the end of the piston rod at the lower end of the cylinder 54, and the pressing table 52 is fixed at the bottom of the lifting plate 55. When the cylinder 54 is working, it can drive the lifting plate 55 to move up and down, so the pressing table 52 can be raised and lowered.

[0015] like Figure 2 As shown, the placement table 51 has a first placement groove 511 and a second placement groove 512 distributed on the left and right, the hose 6 is inserted into the first placement groove 511 and the second placement groove 512, the upper ends of the first placement groove 511 and the second placement groove 512 are both open, the first pressing block 521 extends into the first placement groove 511, and the second pressing block 522 extends into the second placement groove 512. Because one end of the hose 6 of the cooling circuit of the hydrogen energy vehicle usually has two pipe openings, the first placement groove 511 and the second placement groove 512 are set to facilitate the placement of the two pipe openings.

[0016] In order to enable the first pressing block 521 and the second pressing block 522 to stably press the hose 6 , the lower end surfaces of the first pressing block 521 and the second pressing block 522 are both arc-shaped concave surfaces for contacting the outer wall surface of the hose 6 .

[0017] The utility model provides a hose pressure cycle test bench, in which the hose 6 can be placed on the placement table 51, and the pressing table 52 will press the hose 6 after moving downward. The hose 6 is pressed during the inflation and deflation cycle test and is not prone to movement or falling. After the test, the pressing table 52 moves upward, and the hose 6 can be removed.

[0018] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
