Abstract
The utility model discloses a water gun for fire fighting, comprising a connecting body, a gun body and a nozzle which are orderly connected. The gun body and the nozzle are integrally formed. A cylindrical assembling slot is arranged at the connecting position of the connecting body and the gun body. The internal perisporium of the cylindrical assembling slot is provided with an inner screw. The periphery of an end part which the gun body is connected with the connecting body is provided with an outer screw. By the matching of the inner screw and the outer screw, the gun body is fixedly connected with the connecting body. Owing to the gun body and the nozzle are integrally formed, the sealing performance and strength of the water gun for fire fighting are raised, and the appearance is much beautiful; meanwhile owing to the strength is raised, a conic pressurizing face in the gun body can be longer, and the nozzle is able to spurt out water columns with bigger pressure; adopting the matching of screws, the gun body is connected with the connecting body, which enables one piece of the gun body and the connecting body to be singly replaced when the piece is damaged.
Description
Technical field
The utility model relates to fire-fighting equipment, specifically is meant the hydraulic giant that is used for fire-fighting.
Background technology
Hydraulic giant a kind of fire-fighting equipment that is absolutely necessary, with reference to Fig. 4, existing hydraulic giant mainly is made up of connection body 1, rifle body 2, nozzle 3, connects body 1 and is connected to the water source, 20 pairs of water of conical pressurized segment in the rifle body 2 pressurize, ejection the face of cylinder 310 in nozzle oral cavity 1.Because rifle body 2, nozzle 3 will bear bigger hydraulic pressure, and be therefore, also higher to the requirement of its sealing property and intensity.
The aforementioned existing hydraulic giant that is used for fire-fighting, mainly there is following problem: one, because the restriction on original foundry engieering, the rifle body 2 of hydraulic giant and nozzle 3 separated into two parts independence castings, its junction 203 adopts internal and external threads to cooperate, the machining program is loaded down with trivial details, and its junction 203 is also to the sealing property of hydraulic giant, intensity and outward appearance have produced certain negative effect, must take certain measure to guarantee the sealing property and the intensity of this junction, this is with regard to the corresponding manufacturing cost that improves hydraulic giant, simultaneously, in order to guarantee its reliability, the conical pressurized segment 20 in the rifle body 2 is shorter, so the range of the water column of its ejection is shorter; Two, the connection body 1 of hydraulic giant and rifle body 2 are integrally formed, can not dismantle, if wherein damage then must all be changed.
Therefore, if can develop the hydraulic giant of a kind of good seal performance, intensity height, far firing range, low cost of manufacture, will improve firemanic efficient greatly, increase the security that hydraulic giant uses.
The utility model content
The utility model provides a kind of hydraulic giant that is used for fire-fighting, its main purpose is to overcome existing hydraulic giant because its rifle body and nozzle separated into two parts independence casting, its sealing property, intensity are relatively poor, and cost is higher, the shortcoming that the pressure of the water column of ejection is lower;
It is integrally formed and can not dismantle that another purpose of the present utility model is to overcome the connection body of existing hydraulic giant and rifle body, if wherein damage, the shortcoming that must all change.
The utility model adopts following technical scheme: the hydraulic giant that is used for fire-fighting, comprise the connection body, rifle body and the nozzle that connect successively, rifle body and nozzle are one-body molded, connect body and rifle body junction and be provided with cylindrical fitting recess, the internal perisporium of this cylindrical fitting recess is provided with internal thread, the rifle body is provided with external screw thread with being connected the end outer peripheral face that body connects, the rifle body be connected body pass through this internal thread with externally threaded cooperate fixedly connected.
Aforementioned rifle body is provided with Gask-O-Seal with being connected between end face that body connects and the bottom surface that is connected the cylindrical fitting recess of body.
The taper seat of the strip that the madial wall of aforementioned rifle body and nozzle forms is complete, shrink gradually to the nozzle direction, jet hole forms a cylinder.
External week of aforesaid rifle, the middle part outwards convexed to form an annular boss, and this annular boss surface is provided with anti-skidding reticulate pattern, and this annular boss is provided with annular fitting recess by connecting the body place.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, because rifle body and nozzle are one-body molded, its sealing property, intensity improve greatly, outward appearance is also more attractive in appearance, owing to the raising of intensity, the taper shape of rifle body inside adds pressure surface can be longer, so its range is also far away simultaneously; If two, the rifle body adopts threaded engagement to connect the body damage with being connected body, can change the connection body separately.

Fig. 2 pulls down the cross-sectional view that connects behind the body for the utility model;
Fig. 3 connects the cross-sectional view of body for the utility model;
Fig. 4 is the cross-sectional view of existing hydraulic giant.
The specific embodiment
The specific embodiment of the present utility model, referring to figs. 1 through Fig. 3, this hydraulic giant that is used for fire-fighting comprises connection body 1, rifle body 2 and the nozzle 3 that connects successively, rifle body 2 and nozzle 3 adopt extrusion process one-body molded, connect body 1 and be provided with cylindrical fitting recess 10 with rifle body 2 junctions, the internal perisporium of this cylindrical fitting recess 10 is provided with internal thread 101, rifle body 2 is provided with external screw thread 22 with being connected an end 22 outer peripheral faces that body 1 connects, and to pass through this internal thread 101 fixedly connected with cooperating of external screw thread 22 with being connected body 1 for rifle body 2.Rifle body 2 is provided with Gask-O-Seal 4 with being connected between end face that body 1 connects and the bottom surface that is connected body 1 cylindrical fitting recess 10.The taper seat 20 of the strip that the madial wall of rifle body 2 and nozzle 3 forms is complete, shrink gradually to the nozzle direction forms cylinders 310 in the jet hole 31.Because rifle body 2 and nozzle 3 are one-body molded, thereby can bear bigger pressure, so the length of taper seat 20 can do greatlyyer, to obtain bigger pressure.
Rifle body 2 peripheries middle part outwards convexes to form an annular boss 21, these annular boss 21 surfaces are provided with anti-skidding reticulate pattern 211, be convenient to the user with holding, this annular boss 21 is provided with annular fitting recess 210 by connecting body 1 one sides, is used for assembling with outside fixed mount or bracing frame.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the improvement of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
