Description
Technical Field
The invention relates to a fire-fighting lance with a swingable nozzle, and belongs to the technical field of fire-fighting lances.
Background
The fire-fighting lance is a fire-fighting tool, and is connected with a water hose when in use, and the lance head of the fire-fighting lance can spray dense and full water flow. The water jet can be divided into a straight-flow water gun and a dispersion water gun according to different water jet forms and characteristics. The existing common fire-fighting lance has single function, and can only produce direct-flow water columns when the direct-flow lance is used for fighting fire, although the impact force is large and the range is far, the direct-flow lance cannot reduce the temperature of a fire scene in a large area, a fireman is easily burnt by flame when operating, the protection effect cannot be achieved, the fire-fighting lance needs to be dispersed at the moment, and the range suppresses the flame of the surrounding environment. The dispersion spray gun has a disadvantage that the gun head is easily blocked by impurities such as silt. Therefore, the fire-fighting lance with the swingable nozzle is designed, can be switched in time under two states of direct current and dispersive injection, and can not block the lance head due to silt in the dispersive injection state.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a fire-fighting lance with a swingable nozzle comprises a lance head, a tube body, a pin shaft, a support rod, a stop block and a screw;
the gun head is screwed and sleeved at the upper end of the tube body;
the lower end of the support rod is movably hinged to the middle of the pin shaft, the pin shaft is fixed inside the upper end of the pipe body, the pin shaft is located on the diameter of the pipe body, and a stop block is fixed to the upper end of the support rod through a screw;
the stopper comprises circular baffle on upper portion and conical kuppe of lower part, and circular baffle and the coincidence of conical kuppe bottom surface, and the screw passes circular baffle and conical kuppe in proper order and fixed with the spiro union of cradling piece upper end, and circular baffle is located outside the body, and circular baffle diameter is less than rifle head internal diameter, and rifle head cover is outside circular baffle.
In a preferable embodiment, a circle of groove is formed in the outer side of the upper end of the pipe body, a sealing ring is arranged in the groove, and the outer wall of the pipe body is sealed with the inner wall of the gun head through the sealing ring.
As a preferred example, the diameter of the circular baffle is 2-8mm smaller than the inner diameter of the lance tip.
As a preferred example, the pin shaft is provided with a pair of limiting clamping rings, and the limiting clamping rings are arranged on two sides of the support rod.
The invention has the beneficial effects that:
(1) the relative positions of the gun head and the stop block are adjusted by manually rotating the gun head, so that the free switching of the water gun in a direct-current and dispersed injection state is realized;
(2) when the gun head approaches the stop block, the discharged water is changed into a dispersed spray shape, and when the gun head exceeds the stop block, the discharged water is changed into a direct-current spray shape;
(3) under normal use condition, because rivers are even, the each direction atress of dog is more even, is in the middle of the body all the time, when mouth of pipe department met silt, can lead to the dog skew, has silt one side space grow, and rivers grow thereupon, washes away silt, can prevent to block up.
