[0022] like Figure 1 and Figure 2 As shown, a device for testing the compressive capacity of a lead-acid battery comprises a placement table 1. The placement table 1 is a flat plate having a placement area for placing the lead-acid battery to be tested, that is, the top surface of the placement table 1.

[0023] A horizontally arranged mounting plate 2 is provided above the placement table 1. The mounting plate 2 is also a flat plate. The mounting plate 2 is arranged parallel to the placement table 1 and both are arranged horizontally. The mounting plate 1 is fixedly mounted on the placement table 1 through columns 3. The columns 3 include two groups located on opposite sides of the placement table 1.

[0024] In the device of the present application, the upper and lower ends of the column 3 are fixed to the mounting plate 2 and the placement table 1 by screws or bolts. In the structure shown in the figure, the placement table 1, the mounting plate 2, and the column 3 are fixed by screws. This makes it easy to disassemble and assemble. When it is necessary to apply to lead-acid batteries of different heights, a column 3 of a suitable height can be selected for installation.

[0025] The material of the placement table 1, the mounting plate 2, and the column 3 can be steel.

[0026] The device of the present application further comprises a pressure member, which comprises a pressure rod 4 arranged vertically and movably passing through the mounting plate 2 , and a pressure block 5 is provided at a portion of the pressure rod 4 located above the mounting plate 2 .

[0027] The pressure rod 4 is a screw rod, and the pressure block 5 has a mounting hole for the screw rod to pass through. The mounting hole is vertically arranged. When the mounting hole is inserted into the vertically arranged screw rod, the center of gravity of the pressure block 5 is located on the screw rod, so that when in use, the entire pressure piece can provide pressure vertically downward.

[0028] The screw rod is provided with fixing nuts 6 on the upper and lower surfaces of the pressing block 5. When in use, the fixing nuts 6 on the lower surface of the pressing block 5 are suspended on the mounting plate 2. That is, the gravity of the pressing block 5 can be fully transmitted to the lead-acid battery to be tested through the pressing rod 4.

[0029] In a preferred embodiment, the pressing block 5 is in the shape of a cuboid and weighs 25 kg ± 1 kg.

[0030] The bottom surface of the pressure rod 4 is provided with a cushion block 7, and the bottom surface of the cushion block 7 is a plane. The top surface of the cushion block 7 has a screw hole for threaded installation with the bottom thread of the screw rod as the pressure rod 4. The screw rod is provided with a positioning locking nut 8 against the cushion block 7 above the cushion block 7. The cushion block 7 can be made of plastic material to prevent the screw rod as the pressure rod 4 from directly pressing on the lead-acid battery and causing damage due to non-load-bearing reasons.

[0031] When in use, the lead-acid battery to be tested is placed in the placement area of ​​the placement table 1, and then the pressure rod 4 relies on its own gravity and the pressure block 5 to press on the position to be tested of the lead-acid battery. After a period of testing, the lead-acid battery is taken out and the deformation of the pressed position is tested. The device and the lead-acid battery can be placed in a thermostatic box under certain temperature and humidity conditions to shorten the testing time.
