Description

Technical Field

[0001] The utility model relates to the technical field of plastic cases for lead-acid batteries, in particular to a flame-retardant and leak-proof plastic case for lead-acid batteries. Background Technique

[0002] All storage batteries with acidic aqueous solutions as electrolytes are collectively referred to as acidic storage batteries, among which the most typical one is the lead-acid battery. The main advantages of acidic storage batteries are relatively high working voltage, wide operating temperature range, good high and low rate discharge performance, rich raw material sources, and low price. Its disadvantages are relatively low energy density, resulting in relatively large volume and weight. For lead-acid batteries, the positive electrode is lead dioxide, the negative electrode is spongy lead, the electrolyte is sulfuric acid aqueous solution, the separator (diaphragm) uses microporous rubber separator, microporous plastic separator or other materials according to different types of lead batteries, and the battery case is made of hard rubber, engineering plastics, fiberglass and other materials. During the use of lead-acid batteries, a plastic case is required to play a protective role. However, the current plastic case has poor strength, resulting in easy damage and leakage due to being impacted by external objects, and poor flame retardancy, resulting in easy ignition during a fire. Therefore, we propose a flame-retardant and leak-proof plastic case for lead-acid batteries. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a flame-retardant and leak-proof plastic case for lead-acid batteries. The plug-in puncture-proof plate and the protection plate can effectively prevent the plastic case from being damaged and leaking due to impact. The set sealing gasket can increase the sealing performance between the case and the case cover, and the filled flame-retardant filler and the flame-retardant coating can improve the fire resistance of the plastic case and slow down the spread speed of the flame, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a flame-retardant and leak-proof plastic case for lead-acid batteries, including a case and a protection unit;

[0009] Further, the quick-release unit includes a rotating wheel, a screw, a fixing frame, a clamping hole and an elastic bump. There are two elastic bumps which are respectively fixed on the left and right side surfaces inside the shell. Clamping holes corresponding to the elastic bumps are formed on both the left and right side surfaces of the fixing frame. There are two screws which are respectively rotatably connected to the shaft holes on both sides of the top surface of the shell cover. The top end of the screw is fixed with a rotating wheel. The elastic bump is clamped with the clamping hole to install the fixing frame, so that the electrode plate inside the shell can be tightly fixed. And rotating the rotating wheel to make the screw threadedly connected with the screw hole on the top surface of the fixing frame can quickly disassemble and assemble the shell cover and the shell.

[0010] Further, the protection unit further includes a fixing groove and an anti-detachment block. The fixing groove is formed on the front and rear side surfaces of the shell. The anti-detachment block is inserted into the through groove on the surface of the protection plate. The anti-detachment block passes through the through groove and is inserted into the fixing groove, so as to facilitate the installation and disassembly of the protection plate.

[0011] Further, it further includes mounting blocks, a sealing gasket and a handle. There are two handles which are respectively rotatably connected to the grooves on both sides of the top surface of the shell cover. Mounting blocks are fixed on both sides of the top surface of the sealing gasket. The mounting blocks are inserted into the mounting grooves on the bottom surface of the shell cover. The mounting blocks are inserted into the mounting grooves to fix the sealing gasket. The sealing gasket can increase the sealing performance between the shell and the shell cover to prevent the solution inside the shell from leaking. The hidden handle facilitates the personnel to carry the plastic shell and does not affect the subsequent installation at the same time.

[0012] Further, it further includes a slot and a partition plate. The slots are evenly formed on the top surface of the fixing frame. The partition plate is inserted into the slot. The partition plate inserted into the slot can place the electrode plates separately to meet different installation requirements.
