[0002] Energy storage fire extinguisher is a kind of fire-fighting equipment specially used in energy storage facilities. According to different fire extinguishing agents, it can be divided into many types, such as inert gas fire extinguisher, water-based fire extinguisher, dry powder fire extinguisher, etc. Among them, inert gas fire extinguisher and perfluorohexanone fire extinguishing device are widely used in energy storage facilities because of their environmental protection, high efficiency and no residue. The valve handle of energy storage fire extinguisher is an important part of operating the fire extinguisher. It allows the user to quickly and effectively start the fire extinguishing device in an emergency. The valve handle includes an upper handle and a lower handle. The lower handle is fixedly connected to the valve body, and the lower handle is provided with a lower socket. The upper handle is hinged to the valve body, and the upper handle is provided with an upper socket that can be aligned with the lower socket. The upper end of the pressing rod is located between the upper handle and the lower handle. When not in use, the safety pin is inserted in the upper socket and the lower socket at the same time, so that the upper handle cannot be pressed down to squeeze the pressing rod. When in use, pull out the safety pin, hold the valve handle with one hand and press it to open. The stamping process is usually involved in the production process of the valve handle.

However, the buffering is only based on the elastic force of the buffer springs, which puts a heavy load on the buffer springs. As the number of stamping times increases, the buffer springs are prone to fatigue damage and the buffering effect deteriorates. Utility Model Content

A slide plate 12 is fixedly connected to one side, and the slide plates 12 are slidably connected to the outer wall of the support plate 3 on the same side. A side of the slide plate 12 that is close to the support plate 3 on the same side is fixedly connected to a plurality of friction strips 13. The number of friction strips 13 is the same as the number of friction grooves 4 and corresponds one to one. The friction strips 13 are slidably connected to the corresponding friction grooves 4. A mounting groove 14 is provided in the middle of the front and rear sides of the upper end of the bottom plate 1. A connecting block 15 is detachably connected to the middle of the mounting groove 14 through a fixing pin 16. Connecting plug plates 17 are fixedly connected to both sides of the connecting block 15. The connecting plug plates 17 are inserted into the interior of the slider 11 on the same side and are locked by a pin shaft to connect the connecting block 15 and the slider 11 together, so that it is convenient to press against the lower end of the spring buffer rod 9 when the spring buffer rod 9 is squeezed.

[0019] The middle parts of both sides of the lifting plate 6 are aligned with the hydraulic cylinder 5 on the same side. The lifting plate 6 is slidably connected to the inside of the two support plates 3 to ensure that the lifting plate 6 will not shake when moving up and down.
