Problems solved by technology

[0002] The traditional fire hose nozzle connects the nozzle of the nozzle to the hose / water pipe through the pipe tooth interface and the hose / water pipe interface, because the interface standards of each country are different, so the hose / water pipe joints in each country cannot be used interchangeably
At the same time, there is nothing in the traditional fire hose connector to waste the available space. The multi-interface connection structure not only is cumbersome to operate but also increases the weight of the fire hose, which is not convenient for firefighters to use.

Embodiment 1

[0033] like figure 1 , figure 2 and Figure 7 as shown, figure 2 Invisible fire water gun of the present invention and figure 1 Compared with the traditional fire water gun, the weight of the water spray gun is reduced, and at the same time, the space in the water gun joint is efficiently used to avoid space waste.

[0034] The invisible fire water gun described in the first embodiment of the present invention includes:

[0035] Interface body 1, inner threaded outer wall 2, outer threaded water spray pipe 3 and hose / pipe 4 (can be hose or water pipe), small diameter can be 20mm-33mm, water hose can be 1.5mm-75mm, water pipe It is round with or without pressure, and the hose is flat without pressure and is round with pressure. Wherein, the externally threaded water spray pipe 3 is rotated and inserted into the internally threaded outer wall 2, and the other side of the internally threaded external wall 2 has an annular groove 5 relative to the interface body 1, and the ...

Embodiment 2

[0044] like image 3 As shown, the improvement of the invisible fire water gun in the embodiment compared with the embodiment 1 is that the outer wall 2 of the internal thread can be provided with a plurality of annular grooves for fixing, and one or more metal wires are arranged in each annular groove. In the embodiment, there are 4 annular grooves arranged obliquely, and the fixing components used in each annular groove are 3 metal wires.

Embodiment 3

[0046] like Figure 4 , 5 , 8, the improvement of the invisible fire water gun in this embodiment relative to Embodiment 1 is that: the circular hole chassis 14 is inserted in the annular groove 5, and the T-shaped bolt 15 is inserted in the external thread water spray In the pipe 3, the bolt 15 passes through the central round hole of the round hole chassis 14 and is fixed on the round hole chassis 14 by a nut 16, the bolt end face 17 is located outside the interface body end face 18, and the The diameter of the bolt end surface 17 is smaller than the diameter of the circular groove in the interface body 1, and the bolt end surface 17 is provided with a soft sealing structure 19 on the side close to the external threaded water spray pipe 3, and the interior of the interface body 1 is set The three-dimensional structure 20 is necked in an arc shape. The external thread water spray pipe 3 is fixed (glued) on the end face of the interface body 1 . The structure of the water s...

Abstract

The invention discloses a hidden fire-fighting lance. The hidden fire-fighting lance comprises a joint body, an internally-threaded outer wall, an externally-threaded water spray pipe and a water hose / water pipe, wherein the externally-threaded water spray pipe is rotationally inserted in the internally-threaded outer wall, an annular groove is formed in the other side, opposite to the joint body, of the internally-threaded outer wall, and the water hose / water pipe is fixed on the internally-threaded outer wall in a sleeve manner. The hidden fire-fighting lance has the benefits as follows: mechanical parts of traditional fire-fighting lances are moved into water hoses / water pipes, structures are improved, the traditional joint connection step is omitted, inconvenience caused by inconsistent standards of water hose / water pipe joints in all countries is avoided, and the hidden fire-fighting lance can be in common use in all the countries; the whole structure of the fire-fighting lance is improved, the weight of the fire-fighting lance is decreased, meanwhile, space inside a connecting object of the fire-fighting lance is efficiently utilized, and space waste is avoided; the hidden fire-fighting lance is small in size and light, so that the fire-fighting lance can be fastened on a fire-fighting machine relatively easily and can be used by a fireman conveniently.

Description

technical field [0001] The invention belongs to the field of fire-fighting equipment, in particular to an invisible waterproof gun. Background technique [0002] The traditional fire hose nozzle connects the nozzle of the nozzle to the hose / pipe through the hose joint and the hose / pipe interface. Because the interface standards of each country are different, the hose / pipe joints in each country cannot be used interchangeably. At the same time, there is nothing in the traditional fire hose connector to waste the available space, and the multi-interface connection structure is not only cumbersome to operate but also increases the weight of the fire hose, which is not convenient for firefighters to use. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a portable, space-saving and universal fire hose. [0004] In order to achieve the above object, the present invention discloses a stealth fire water gun...
