Description
Technical Field
The invention relates to the field of fire extinguishers, in particular to a fire extinguisher valve structure convenient for pulling out a safety pin.
Background
The fire extinguisher is a portable fire extinguishing tool. Chemical substances are placed in the fire extinguisher to extinguish fire. The fire extinguisher is one of common fire-proof facilities, is stored in public places or places where fire disasters may happen, and different fire extinguishers of different types are filled with different components and are specially designed for different fires. Care must be taken in use to avoid adverse effects and risks.
In the existing fire extinguisher structure, a safety pin respectively penetrates through pin holes formed in turned edges of an upper pressing handle and a lower carrying handle to be fixed. When the fire extinguisher is used, the fire extinguishing agent in the fire extinguisher can be sprayed only by pressing the upper pressing handle after the safety pin is pulled out, and if the safety pin is not pulled out, the upper pressing handle is fixed by the safety pin even if the upper pressing handle is pressed, so the fire extinguishing agent in the fire extinguisher can not be sprayed because the upper pressing handle cannot be pressed. However, the fire extinguisher with the structure has a disadvantage that people are generally nervous and afraid when a fire breaks out, so that even people who have experience in using the fire extinguisher before or people who have been trained in fire extinguishment still can involuntarily or instinctively press the upper pressing handle downwards when the fire extinguisher is used, and then the safety pin is prepared to be pulled out. The safety pin structure of the traditional fire extinguisher leads to that when the safety pin is arranged, once the upper pressing handle is pressed down, the upper pressing handle can not be pressed down, but a larger acting force can be generated on the safety pin, so that the maximum static friction force between the safety pin and the upper pressing handle and between the safety pin and the lower lifting handle is increased, and in addition, the stress and fear caused by fire disasters can lead to the fact that the safety pin is not easy to pull out, and further the fire extinguishment is influenced.
Disclosure of Invention
The invention aims to: the fire extinguisher valve structure has the advantages that the defects of the prior art are overcome, the safety effect of the fire extinguisher can be ensured, in an emergency, even if a user tightly holds the upper pressing handle and the lower carrying handle simultaneously due to tension, the pulling-out of the safety pin is not influenced, and the user can easily pull out the safety pin to extinguish the fire; through the action of the pin hole B, the safety pin can be inserted into the pin hole B after being pulled out of the pin hole A, so that the loss of the safety pin is avoided, the resource is saved, and the fire extinguishing operation is not influenced; the point corresponding to the longitudinal section through the pin hole A is positioned on a connecting line of the rotating shaft B and the point corresponding to the longitudinal section; or the point of the pin hole A corresponding to the longitudinal section is positioned on one side, facing the valve body, of a connecting line of the rotating shaft B corresponding to the point of the longitudinal section, so that the upper connecting plate and the lower connecting plate simultaneously swing towards one side of the valve body after the safety pin is pulled out of the pin hole A, and the situation that the fire extinguishing operation is influenced by the fact that the upper connecting plate and the lower connecting plate are contacted with the hand of a user when swinging is avoided; through the effect of limiting plate, avoid upper junction plate and lower connecting plate to put in one side of keeping away from the valve body when the safety pin is arranged in to the cover, and then prevent when the safety pin follow pinhole A extract after, upper junction plate and lower connecting plate are simultaneously to valve body one side swing, avoid upper junction plate and lower connecting plate swing when contacting with user's hand and influence the operation of putting out a fire.
The technical scheme adopted by the invention is as follows:
the fire extinguisher valve structure convenient for pulling out the safety pin comprises a valve body, wherein a valve rod assembly is arranged on the upper portion in the valve body, a lower carrying handle and an upper pressing handle are sequentially arranged on the same side of the top of the valve body from bottom to top, flanges are upwards arranged on the two side edges of the lower carrying handle, flanges are downwards arranged on the two side edges of the upper pressing handle, the lower carrying handle is fixed with the valve body, the upper pressing handle is connected with the valve body in a vertically swinging mode through a rotating shaft A, the top end of the valve rod assembly is located between the upper pressing handle and the lower carrying handle, the lower carrying handle is connected with the upper pressing handle through a lower connecting plate, one end of the lower connecting plate is rotatably connected with the lower carrying handle, one end of the upper connecting plate is rotatably connected with an upper pressing plate, a through hole is formed in each of the other end of the lower connecting plate and the other end of the upper connecting plate, the through hole is sleeved on a pin rod of the safety pin, the pin penetrates through pin holes A symmetrically formed in the flanges on the two sides of the lower carrying handle, and is fixed with the lower carrying handle, and a space is formed between the top of the upper pressing handle and the valve rod assembly.
