Problems solved by technology
Different from the static use environment of communication power, the use of automobiles belongs to the mobile environment. Long-term high-temperature vibration will cause the exhaust plug to loosen and affect the battery life. Therefore, it is necessary to design a new exhaust plug for mobile environments such as automobiles.

Embodiment Construction
[0013] Such as Figure 1 to Figure 5 shown. The present invention has a valve-controlled battery exhaust plug with a stop screw. A raised stop screw 4 is provided below the thread 6 of the existing exhaust screw 2. The stop screw 4 is a bump. 4 Cooperating with the blocking nail 5 in the threaded hole of the valve-controlled battery cover 1, it can prevent the exhaust plug 2 from rotating in reverse and play a role of anti-retreat, so that it can effectively prevent the exhaust plug 2 from loosening in a vibration environment and ensure normal working condition. Simultaneously because back-stop nail 4 is at the bottom of thread 6, when exhaust plug 2 is screwed in and out, it will not interfere with the thread of big cover 1 threaded hole, and thread will not be damaged, which can ensure that sealing ring 3 is tightly sealed. The thread 6 of the exhaust plug 2 is a rectangular thread with a rectangular cross-section, and the circumferential length of the rectangular thread i...

Abstract
The title of the present invention is a valve-controlled battery exhaust plug with a back-stop nail. The invention belongs to the technical field of valve-regulated lead-acid batteries. It mainly solves the problem that the existing exhaust plug is easy to loosen in the mobile environment and affects the battery life. Its main features are: there is a protruding stop nail under the thread of the exhaust plug, which is matched with the blocking nail in the threaded hole of the valve-controlled battery cover, combined with the stop screw on the big cover hole. The blocking nail can effectively prevent the exhaust plug from loosening in the vibration environment, ensure the normal working condition, and play a stable and reliable role in the bumpy car environment. The invention has the characteristics that it can be used in a mobile environment such as a new energy vehicle to prevent the exhaust plug from loosening, and is mainly used in a vehicle valve-regulated lead-acid battery.
Description
technical field [0001] The invention belongs to the technical field of valve-regulated lead-acid batteries, and in particular relates to a valve-controlled battery exhaust plug with a back-stop nail. Background technique [0002] Valve-regulated lead-acid battery means that there is pressure inside the battery. When the pressure reaches a certain limit, a valve opens. When the pressure drops, the valve automatically closes. Therefore, there is an exhaust plug with a valve compared with ordinary lead-acid batteries, so it is called A valve-regulated lead-acid battery. Generally, valve-regulated batteries are widely used in the field of communication power, and with the rise of new energy vehicles, they have begun to be applied to the automotive field. Different from the static use environment of communication power, the use of automobiles belongs to the mobile environment. Long-term high-temperature vibration will cause the exhaust plug to loosen and affect the battery life....
