Description

Technical Field

[0001] This utility model belongs to the field of lead-acid batteries, specifically relating to an auxiliary tooling for placing a protection board. Background Technology

[0002] Chinese Patent (Announcement No. CN 208423089 U, Announcement Date 2019.01.22) discloses a protective plate that can effectively prevent short circuits caused by floating powder at the top of the electrode group. The toothed structure at the end of the protective plate has slots that mate with the lugs below the positive busbar. Currently, the protective plates are mainly installed manually, one by one, on top of the electrode group after the electrode group has been inserted into the slot.

[0003] Reducing battery costs while maintaining battery performance and dimensions is a critical issue that battery manufacturers urgently need to address in the face of fierce market competition. Based on this background, batteries with low-profile plates and high-profile battery compartments (each compartment measuring 160*80mm) present the following problems when installing the protection board: Firstly, the reduced height of the busbar inside the battery compartment lowers the installation position of the protection board. Since the battery compartment size is 160*80mm, it is difficult for an adult's hand to fit inside, making manual installation of the protection board challenging. Secondly, the reduced busbar height makes it difficult for the toothed structure at the end of the protection board to fit into the gap between the two lugs when the protection board cannot be laid flat, further increasing the difficulty of installation. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide an auxiliary tooling for placing a protection plate, thereby solving the problem of installing the protection plate in a battery with a short electrode plate and a tall tank.

[0005] The technical solution of this utility model is as follows: it includes a grip, a base at the bottom of the grip, a pushing assembly for pushing the protective plate on the base, the pushing assembly includes a cylinder and a telescopic component, the telescopic component is a rectangular plate, the long end face of the front end of the rectangular plate is the end face for pushing the protective plate, the middle of the rear end of the rectangular plate is connected to the piston rod of the cylinder, there is an air inlet pipe inside the grip, there is an air inlet nozzle on the side of the grip for air to enter the air inlet pipe, an air inlet valve is installed on the air inlet pipe near the air inlet nozzle, the lower end of the air inlet pipe is connected to the cylinder, and there is a switch assembly on the upper part of the grip for controlling the opening / closing of the air inlet valve.

[0006] The switch assembly includes an inductor coil placed inside the grip and a control button placed outside the grip.

[0007] During operation, the inductor coil and the control button at the top of the handle control the air intake valve. When the control button is pressed, the inductor coil works, lifting the air intake valve and allowing air to flow through the air intake pipe. When the control button is closed, the inductor coil stops working, the air intake valve falls back, and the air intake pipe is blocked from flowing through.

[0008] The cylinder barrel is fixed to the base.

[0009] The base has a positioning groove for positioning the telescopic component.

[0010] The bottom surface of the base is flat.

[0011] The grip is cylindrical; the lower part of the intake valve is embedded in the intake pipe.

[0012] The intake pipe includes a vertical section and a horizontal section connected to the vertical section. The port of the horizontal section is connected to the intake nozzle, and the intake valve is installed at the connection between the horizontal section and the vertical section.

[0013] The protective plate placement auxiliary tool of this utility model can be used to place the protective plate, resulting in high installation quality and efficiency. It is especially suitable for the installation of protective plates in batteries with short plates and tall cell bodies. Attached Figure Description
