Description

A battery opening and closing valve detection device with a universal clamping mechanism

technical field

    The utility model relates to the field of battery production, in particular to a battery opening and closing valve detection device provided with a universal clamping mechanism.

Background technique

Valve-regulated sealed lead-acid batteries are widely recognized by users because they do not require maintenance, have high reliability and long service life. The safety valve is a very important part, and the opening and closing pressure of the rubber cap of the safety valve is a very critical indicator for battery safety performance requirements. The opening and closing valve detection instrument currently used does not have a device for clamping the battery cover. The tester must use a ventilation tube to wrap raw tape every time to match the valve hole of the battery cover. The tightness of the tube and the hole must ensure that no air leaks. With the increasing development of new battery products, the structure and valve hole diameter of each product are different, and the inspection of the purchased safety valve is very cumbersome for the inspectors, and the operation efficiency is very low. In the water inspection of the pool, especially in winter, the water temperature is too low to meet the requirements of constant temperature inspection and other factors, which directly affect the accuracy of the on-off valve inspection. the

A guide post is fixedly connected between the middle of the fixed plate and the base. The guide post below is provided with a return spring, the other end of the pressure plate is provided with a splint groove, a pressure block is arranged in the splint groove, and a positioning groove is arranged in the middle of the pressure plate. in the slot. 

A further improvement solution of the utility model is that the cross-sectional shape of the base is "Xiang" type.

A further improvement of the utility model is that a handle is provided at the top of the screw jack. the

The further improvement of the utility model is that the bottom of the top mouth is connected with the air intake pipe through the air pipe joint. the

Compared with the prior art, the utility model has the following obvious advantages:

1. Place the hole at the bottom of the valve to be inspected in the battery cover on the positioning nozzle of the utility model, then put a rubber cap on the valve hole, and then press a transparent cover plate on it, and press the pressing block of the pressing mechanism tightly The transparent cover plate can realize the tight air-tight cooperation between the valve hole and the intake pipe of the battery opening and closing valve detection device, which is convenient and fast to operate, and can improve work efficiency and detection accuracy. It is suitable for valves with different apertures and has strong versatility.

2. The utility model only needs to fill the hole seat of the safety valve on the surface of the battery middle cover with water to meet the detection requirements, and does not need to put a large amount of water in the pool to save water. the

3. The cross-sectional shape of the base in the utility model is "冂" type, which is suitable for the installation of the talking back. the

4. A handle is provided at the upper end of the screw mandrel in the pressing mechanism of the utility model, which facilitates the operation of the pressing mechanism. the

5. In the utility model, the bottom of the counter mouth is connected with the air intake pipe through the air pipe joint, so as to realize the sealing communication between the counter mouth and the air intake pipe. the
