Description

A valve-regulated sealed lead-acid battery

technical field

The utility model relates to the technical field of accumulators, in particular to a valve-controlled sealed lead-acid accumulator.

Background technique

The basic feature of valve-regulated lead-acid battery is that it does not need to add acid and water for maintenance during use. The battery is a sealed structure, which will not leak acid or discharge acid mist. There is a one-way exhaust valve (also called safety valve) on the battery cover. ), the function of the valve is that when the internal gas volume of the battery exceeds a certain value (usually expressed by the air pressure value), that is, when the internal air pressure of the battery rises to a certain value, the exhaust valve will automatically open, discharge the gas, and then automatically close the valve to prevent Air enters the interior of the battery.

Patent Publication No. CN212303756U proposes a valve-regulated sealed lead-acid battery, which includes a battery body, two limiting frames are symmetrically installed on both sides of the battery body, and four moving frames run through the interior of the four limiting frames. The four moving rods are equipped with springs, and the bottoms of the four moving rods are equipped with moving plates, and the bottoms of the four moving plates are rotatably connected with moving frames. All of the interiors are rotatably connected with moving wheels, inserting rods run through between the four moving plates and the four limiting frames, and bolts run through one ends of the four inserting rods. Squeeze and push the moving plate through the spring, so that the moving frame and the moving wheel move, make the moving wheel touch the ground, and move the device through the moving wheel, so that when the device needs to move, there is no need to waste a lot of time twisting the transmission structure, reducing the user The difficulty of work and the difficulty of moving the device improve the moving efficiency of the device. When this structure is in use, it is necessary to pull the slider to drive the moving rod to move upwards to separate the moving wheel from the ground. Since there are four moving wheels, it is necessary to pull the sliders everywhere, and it is necessary to use the insertion rod to position the moving plate and operate it. It is troublesome to compare, so we provide a valve-regulated sealed lead-acid battery.
