Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting water gun fixing device. Background Art

[0002] A fire hose is a water-jetting tool used for firefighting. When connected to a water hose, it will spray dense and substantial water flows, with the advantages of long range and large water volume. According to the jet form and characteristics, it can be divided into: direct current water gun, spray water gun, multi-purpose water gun, etc.

[0003] The process of using a fire hydrant is generally to open the fire hydrant door, take out the water hose and water gun, and after connecting the water hose to the fire hydrant, at least two operators hold the water gun tightly and aim it at the root of the fire source to spray and extinguish the fire until the fire is completely extinguished. Since the water flow during the spraying process of the high-pressure water gun is very strong, it is difficult to adjust the spray angle while holding the water gun, and it is impossible to accurately aim at the fire source, which creates certain limitations for firefighters to extinguish the fire. In the patent application document with application number: 202322073697.2, a fixing device for a fire water gun is disclosed, which is provided with blocks on the upper and lower sides to clamp the water gun, and the water gun is locked and fixed by screwing the screw. It is generally done by manually screwing the screw, which may cause the blocks on both sides to clamp the water gun with insufficient force, which is easy to loosen, and blocks are required on the opposite sides to clamp the water gun, and the structure is relatively complicated.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 3 A fire-fighting water gun fixing device includes a support base 1, a support rod 2 arranged in the support base 1, a support frame 3 connected to the support rod 2 for left and right rotation, and a water gun fixing sleeve 4 connected to the support frame 3 for up and down rotation. The support rod 2 extends from the support base 1, the support frame 3 is arranged on the protruding end of the support rod 2, and the water gun fixing sleeve 4 is connected to the protruding end of the support frame 3. In this way, the water gun is fixed by the water gun fixing sleeve 4, thereby facilitating the control of the water gun. In order to be able to firmly fix the water gun in the water gun fixing sleeve 4, the shape of the water gun fixing sleeve 4 is designed to be conical, and a plurality of axially distributed opening grooves 41 are provided on one end of the inlet of the water gun fixing sleeve 4, and the width of the opening grooves 41 gradually decreases from the inlet end of the water gun fixing sleeve 4 to the outlet end of the water gun fixing sleeve 4; at the same time, a locking piece 5 is provided on the water gun fixing sleeve 4 to reduce the inner diameter of the inlet end of the water gun fixing sleeve 4. In this way, the water gun can be more firmly clamped in the water gun fixing sleeve 4 for fixation, and the structure is simpler.

[0023] In this solution, the locking member 5 includes a locking sleeve 51 that is sleeved on the inlet end of the water gun fixing sleeve 4. At the same time, the locking sleeve 51 is conical in shape and is connected to the water gun fixing sleeve 4 by a threaded connection. The maximum inner diameter of the locking sleeve 51 is smaller than the maximum outer diameter of the water gun fixing sleeve 4. In this way, when the locking sleeve 51 is on the water gun fixing sleeve 4 and screwed toward its inlet section, the inner diameter of the inlet end of the water gun fixing sleeve 4 is continuously reduced due to the open groove 41 provided on the water gun fixing sleeve 4, thereby clamping the water gun in the water gun fixing sleeve 4.

[0024] In this solution, in order to facilitate the screwing of the locking sleeve 51, a number of armrests 52 are evenly distributed on the outer wall of the conical locking sleeve 51. The armrest 52 can be a lifting ring provided on the outer wall of the conical locking sleeve 51, so as to facilitate grasping by hand. At the same time, the water gun can also be controlled by the armrest 52, and there is no need to hold the water gun to adjust its spray angle.

[0025] In this solution, in order to prevent the locking sleeve 51 from being over-tightened on the water gun fixing sleeve 4 and causing damage to the water gun fixing sleeve 4, a limiting protrusion 42 is provided on one side of the inlet end of the water gun fixing sleeve 4 to limit the locking sleeve 51 from being separated from the water gun fixing sleeve 4.

[0026] In this solution, several anti-slip pads 43 are evenly distributed on the inner wall of the inlet end of the water gun fixing sleeve 4. The anti-slip pads 43 increase the friction between the water gun fixing sleeve 4 and the water gun, so that the water gun can be more firmly fixed in the water gun fixing sleeve 4.

[0027] In this solution, the support frame 3 is U-shaped, and the left and right sides of the water gun fixing sleeve 4 are fixedly connected to a connecting shaft 44 that is rotatably connected to the inner side of the support frame 3. Bearings for supporting the connecting shafts 44 on both sides can also be provided on both sides of the support frame 3, so that the water gun fixing sleeve 4 can rotate up and down around the connecting shaft 44.

[0028] In this solution, a connector 31 is provided at the bottom of the support frame 3, and a docking head 21 that can rotatably cooperate with the connector 31 is provided on the support rod 2. After the connector 31 cooperates with the docking head 21, it can be rotated thereon, so that the water gun fixing sleeve 4 can be rotated at multiple angles, thereby facilitating the control of the water gun spraying direction.

[0029] In this embodiment, to increase the spray range of the water gun, a drive mechanism 6 is provided within the support base 1 to drive the support rod 2 up and down, thereby raising the position of the water gun fixing sleeve 4 and extending the spray coverage of the water gun. Preferably, the drive mechanism 6 includes an electric push rod 61 disposed within the support base 1. The output end of the electric push rod 61 is connected to the bottom of the support rod 2, thereby pushing the support rod 2 up and down, thereby adjusting the vertical position of the water gun fixing sleeve 4. Of course, the drive mechanism 6 can also be a manual drive mechanism 6 such as a hand-cranked lifting mechanism or a screw jack.

[0030] In this solution, the bottom of the support base 1 includes a connecting base 11, which can be fixed on a car for movement and easy transportation. Of course, the bottom of the support base 1 can also be provided with a folding tripod structure, which is convenient for carrying and suitable for different scenarios.

[0031] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
