Problems solved by technology

However, these advantages are also disadvantages for people. These advantages of the fire water gun will increase the recoil of the fire water gun. A firefighter may not be able to control it. Not only is it difficult to move forward, but it also consumes energy. Excessive water pressure may cause firefighters to fly backwards and cause injury to firefighters

Embodiment Construction

[0024] combined with Figure 1-8 The described auxiliary equipment for recoil-reducing straight-line fire water gun includes a shock absorbing mechanism 50, which is set in the hand-held barrel 14, and the shock absorbing mechanism 50 can be fixed on the On the straight-line fire water gun, the recoil force of the water gun can be offset by the elastic potential energy of the four offset springs 12, and then a very small part of the water in the water gun is sprayed on the piston 16 connected to the offset spring 12 through the four water inlet pipes 15, Use the water pressure in the water inlet pipe 15 to offset the recoil force of the offset spring 12 for people, thereby reducing the recoil force of the water pressure in the water gun to people;

[0025] The shock absorbing mechanism 50 includes a nozzle 10, and the nozzle 10 is connected to the piston 16 in the handle barrel 14 through the four offset springs 12. The barrel 14 is evenly provided with four movable grooves 2...

Abstract

The invention discloses straight-flow type fire-fighting lance auxiliary equipment capable of reducing the recoil force. The straight-flow type fire-fighting lance auxiliary equipment comprises a damping mechanism, wherein the damping mechanism is sleeved with a handheld cylinder; the damping mechanism can be fixed to a straight-flow type fire-fighting lance through two fixing mechanisms; the recoil force of the lance can be counteracted through elastic potential energy of four counteracting springs; and then extremely small part of water in the lance is sprayed to pistons connected with counteracting springs through four water inlet pipes. According to the straight-flow type fire-fighting lance auxiliary equipment, the recoil force of the water pressure on a firefighter can be reduced to a great extent, so that the firefighter can well control the fire-fighting lance; the four counteracting springs are arranged, so that energy of the recoil force of the water pressure is counteracted through the elastic potential energy of the counteracting springs; and the inner diameter of a nozzle is smaller than that of the fire-fighting lance, so that water in the fire-fighting lance can enter a movable groove through a water inlet pipe to abut against the pistons, and counter-acting force of the counteracting springs to the firefighter is counteracted. The recoil force of water pressure to people is counteracted through the pressure of a water column.

Description

technical field [0001] The invention relates to the field of shock absorbers, and specifically relates to a direct-flow type fire water gun auxiliary equipment for reducing recoil force. Background technique [0002] Existing straight-line fire-fighting water gun is a kind of fire-fighting water gun commonly used when fire-fighting and extinguishing fire, connects with hose with it and can eject dense and abundant water flow, has advantages such as long range, large water volume. However, these advantages are also disadvantages for people. These advantages of the fire water gun will increase the recoil of the fire water gun. A firefighter may not be able to control it. Not only is it difficult to move forward, but it also consumes energy. Excessive water pressure may cause firefighters to fly backwards and cause injury to firefighters. Contents of the invention [0003] The object of the present invention is to provide a direct-flow type fire water nozzle auxiliary equipm...
