Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the present utility model provides a technical solution: the utility model provides a fixing device of fire-fighting lance, weight box 2 is hollow structure, and the inside of weight box 2 is filled with liquid water, can increase weight of weight box 2 through liquid water injection weight box 2 to improve fixing device's weight, avoid fire-fighting lance 11 to make fixing device displacement cause unable stable control fire-fighting lance 11 when the recoil of spraying.

The cross sections of the first loop 7 and the second loop 9 are of annular structures and can be mutually sleeved, so that the first loop 7 and the second loop 9 can rotate.

The top of the weight box 2 is provided with a matched guide hole near the lower position of the guide post 10, and the fixing frame 5 can be stably lifted through the limiting movement of the guide post 10 in the guide hole, so that the height of the fixing frame 5 is increased.

The inner diameters of the limiting ring 12 and the second ring sleeve 9 are the same, so that the limiting ring 12 and the second ring sleeve 9 can be made. The inner side walls of the two rings are tightly attached together, so that the fire-fighting lance 11 is conveniently inserted into the through limiting ring 12 and the second ring sleeve 9.

One end of the limiting rod 15 penetrates through the limiting ring 12, and the limiting ring 12 limits the limiting rod 15, so that the moving stability of the stop block 14 can be ensured.

The cross section of dog 14 is convex structure, can make the inside wall of dog 14 laminate with the lateral wall of fire-fighting lance 11, and then carries out spacing to fire-fighting lance 11, avoids fire-fighting lance 11 to deviate from in the second ring cover 9.

The rubber pad is embedded in the bottom of the base 1, so that the friction force between the base 1 and the ground is improved, and the base 1 is prevented from retreating under the impact of water flow.

Working principle: when the fire extinguishing device is used, the base 1 is placed at a fire extinguishing position, the box cover 3 is screwed down, water is injected into the weight box 2, the weight of the weight box 2 can be increased through the liquid water injection into the weight box 2, thereby the weight of the fixing device is improved, the phenomenon that the fire-fighting lance 11 cannot stably control the fire-fighting lance 11 due to the displacement of the fixing device caused by the recoil force of the fire-fighting lance 11 during injection is avoided, the box cover 3 is screwed up, the fire-fighting lance 11 penetrates through and is inserted into the second annular sleeve 9, the rotating disc 16 drives the screw 13 to rotate, the stop block 14 at one end of the screw 13 is driven to move, the stop block 14 can be made to move at the limit rod 15, the stop block 14 can be made to move to one side of the protruding position of the fire-fighting lance 11, the fire-fighting lance 11 can be limited through the stop block 14, the fire-fighting lance 11 is prevented from being in the second annular sleeve 9, the fire-fighting lance 11 is connected with the fire-fighting lance, finally, the fire-fighting lance 11 can be sprayed out through the fire-fighting lance 11, the rotation in the vertical direction of the first annular sleeve 7 can be realized through the rotation of the first rotating rod 6, the fire-fighting lance 11 can be further adjusted in the horizontal direction through the second rotating angle of the rotating ring 8, the fire-fighting lance 11 can be adjusted in the horizontal direction, and the horizontal direction can be further adjusted in the horizontal direction of the fire-fighting lance 11 can be realized.

To sum up: this fixing device of fire-fighting lance is through spacing the inside at second ring cover 9 with the one end of fire-fighting lance 11 to realize the support to fire-fighting lance 11, through the rotation on first ring cover 7 vertical direction and the rotation on second ring cover 9 horizontal direction, realize that fire-fighting lance 11 only needs an operator can realize the omnidirectional water spray of fire-fighting lance 11, the water spray recoil that the operator received is little, the adjustment injection angle that can relax, the alignment fire source that can be accurate, the firefighter of being convenient for puts out a fire.
