Abstract

The present invention relates to a fire extinguisher safety pin. In particular, it is important to extinguish a fire by using a fire extinguisher in the early stages of fire. However, in case of a person who is using a fire extinguisher, in case of embarrassment, there is a case where the safety pin holding the extinguisher handle is removed. In this case, a physical pinch point is formed between the lower handle and the upper handle of the fire extinguisher, and a fire extinguisher safety pin is located at the pinch of the fire extinguisher. .

In addition, if the fire extinguisher handle is pushed hard, the fire extinguisher safety pin may be bent or deformed, or when the shock is applied to the upper part of the fire extinguisher handle, the safety pin of the fire extinguisher may be bent or bent and the safety pin may not be pulled out when the actual fire extinguisher should be used. If it does not happen.

For this reason, the fire extinguisher safety pin is prevented from being deformed to prevent the inoperable state of the fire extinguisher due to the safety pin.

Description

Fire Extinguisher Safety Pin Structure

The present invention relates to a safety pin of a fire extinguisher, and in particular, it is important to extinguish a fire by using a manual fire extinguisher in the early stage of a fire, but when a fire occurs, the safety pin does not pull out when the safety pin is removed while holding the handle of the fire extinguisher. do.

Also, the safety pin may be bent by squeezing the handle without removing the safety pin of the fire extinguisher, which may not be removed without using a tool to remove the safety pin from the fire extinguisher. In addition, when a strong impact is applied to the upper part of the handle of the fire extinguisher, the safety pin of the fire extinguisher may be bent, so that the safety pin of the fire extinguisher may not be removed.

This is because a physical pinch is formed between the lower handle and the upper handle of the fire extinguisher, and the fire extinguisher safety pin is located at the pinch of the fire extinguisher, so the safety pin is not removed even if the grip force is weak. There was a case of spreading a large fire.

For this reason, with the extinguisher on the ground, pull out the safety pin and push the lever with the nozzle of the extinguishing agent spray hose toward the center of the fire. Then, the extinguishing agent is ejected and the fire is extinguished. There was a problem to pull the safety pin.

In addition, when the fire extinguisher falls or tilts, the safety pin easily flows out of the fire extinguisher, which causes a loss of the safety pin.

The present invention allows the safety pin to be easily removed even if the fire extinguisher is grasped in the event of a fire, and the safety pin does not easily fall out even if the fire extinguisher falls, so that the safety pin is not lost. In addition, the fire extinguisher safety pin is to prevent deformation such as bending or bending from an external impact.

In view of the above points, the configuration and operation according to the accompanying drawings are as follows.

 (106) Manual fire extinguishers are usually filled with iron in the closed body of fire extinguishing agents with high pressure gas, and in the event of a fire, (104) the fire extinguisher safety pin is removed from the fire extinguisher (202). It is located between (109) the upper and (204) lower erection by the force of. When the (101) upper handle and (102) lower handle of the fire extinguisher are pressed, (101) the upper handle (108) is connected to the trigger pin (109) and the force acting on the upper trigger is (202) This force is transmitted to the lower erection 204, and the valve is opened by pushing down the valve installed at the lower erection 204. At this time, the fire extinguishing agent filled with the high pressure gas is injected into the injection nozzle connected to the rubber hose through the valve opened along the siphon tube (107) installed in the fire extinguisher.

To stop the spraying of the extinguishing agent, release the (101) upper handle and (102) lower handle (103) the force of the spring of the handle (101) the upper handle and (102) the lower handle return to the original position (109) The upper blast is also restored to its original position. (204) The lower eruptor closes the valve with a spring installed therein, and (202) the fire extinguisher trigger ball located at the upper portion of the lower eruptor (202) is restored to its original position. At this time, the (202) fire extinguisher trigger ball provided between the (109) the upper and the 204 lower erection is fixed to a position that can always be triggered by the force of the (201) coil spring.

When inserting the fire extinguisher safety pin (104) into the fire extinguisher (206), loosen the spring bolts (201) and remove the coil spring and shear (205) until the steel bead seal is inclined, tilting the fire extinguisher (202) It flows out. (104) Fire extinguisher safety pin is inserted into the (203) fire extinguisher safety pin hole (202) Fire extinguisher trigger steel ball (205) Iron bead seal and (201) Coil spring (206) Spring bolt assembly (104) Assembly is completed.

The fire extinguisher thus assembled is not deformed because the force is applied to the handle of the fire extinguisher, or even if a strong impact is applied to the upper handle of the fire extinguisher (104), because no direct force is transmitted to the fire extinguisher safety pin (104). . In addition, since the space that is blocked by the fire extinguisher safety pin is formed, (104) the upper handle and the (102) lower handle do not come into contact with each other without removing the fire extinguisher safety pin. Do not spray the medicine even if you grab it.

Modified fire extinguisher safety pins can make fire extinguisher useless in the event of fire. The fire extinguisher safety pin improvement structure of the present invention eliminates the fire extinguisher inoperable state due to the fire extinguisher safety pin because it essentially eliminates the cause of the deformation of the fire extinguisher safety pin. In addition, the fire extinguisher safety pin is easily detached from the fire extinguisher when the fire extinguisher falls, causing the fire extinguisher safety pin to be lost. In this design, the fire extinguisher safety pin is fired by the force of the spring, which is always tensioning the fire extinguisher trigger ball. This is not easily separated.

In addition, even when teaching how to use a manual fire extinguisher that uses powder or gas to prevent fire, the effect of training can be doubled by actually grabbing the handle without removing the safety pin.
