Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure water guns, in particular to a fire-fighting high-pressure water gun convenient to fix. Background Art

[0002] The water gun can carry out continuous large-flow and long-range operations at the fire scene, playing an irreplaceable role in actual combat. With the progress of technology, industrial equipment tends to be large-scale and giant-sized. Especially at the fire scenes in special places such as chemical industrial zones and docks, the fire-fighting water gun has become one of the few equipment that can effectively carry out fire-fighting operations.

[0003] The prior art such as the utility model with the publication number of CN220778912U discloses a fire-fighting high-pressure water gun convenient to fix. This patent adopts a fixing column, and a disassembly mechanism is fixedly arranged inside the fixing column. The disassembly mechanism includes a fixing groove, a telescopic spring, a limiting bottom plate, and a clamping block. Fixing grooves are opened on both sides inside the fixing column. A plurality of telescopic springs are fixedly arranged inside the fixing grooves. A limiting plate is fixedly arranged on one side of the telescopic springs. Two clamping blocks are fixedly arranged at both ends of the side of the limiting plate far away from the telescopic springs. The equipment of the utility model solves the problems that the device does not have multiple fixing devices and cannot effectively prevent the phenomenon that the high-pressure water gun shakes violently due to huge water pressure during the working process. At the same time, it does not contain a shock-absorbing mechanism and cannot effectively relieve the shaking of the fixing column. There is no simple disassembly mechanism, so when the high-pressure water gun is damaged or blocked inside, it cannot be replaced in time, thus affecting fire-fighting rescue.

[0004] During daily work, during the transportation of the equipment, the rotating pipe is not restricted. During the transportation process, the rotating pipe is prone to rotate randomly, easily causing the spray head to collide with the connector, resulting in damage to the spray head and difficult normal use.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A high-pressure water cannon for fire fighting that is easy to fix, including a connector and a limiting device. The upper surface of the connector is fixedly connected with a bracket. A rotating pipe is arranged inside the bracket. A pulling handle is fixedly connected to the surface of the rotating pipe. A spray head is fixedly connected to the side of the rotating pipe. The limiting device is arranged on the surface of the connector. The limiting device includes a limiting column and a connecting block. The connecting block is fixedly connected to the lower surface of the rotating pipe. The limiting column is fixedly connected to the surface of the connector. A sliding hole is cast at one end of the limiting column. A limiting rod is slidably connected to the inner wall of the sliding hole. A limiting groove is opened on the lower surface of the connecting block. The limiting rod is clamped with the inner wall of the limiting groove. A pulling groove is opened on the side of the limiting rod. A limiting block is fixedly connected to the side of the limiting column.

[0007] Furthermore, a limiting hole is opened on the surface of the limiting block. A pull rod is slidably connected to the inner wall of the pulling groove. By setting the pull rod, the clamping rod can be moved, reducing the situation that the clamping rod is difficult to move when the device is in use.

[0008] Furthermore, one end of the pull rod is fixedly connected with a clamping rod. The clamping rod is slidably connected to the inner wall of the limiting hole. The clamping rod is provided to facilitate the limitation of the limiting rod.

[0009] Furthermore, one end of the pull rod is fixedly connected with a first spring. The end of the first spring away from the pull rod is fixedly connected to the inside of the pulling groove. The first spring is provided to facilitate applying a reset elastic force to the pull rod.

[0010] Furthermore, a protective device is arranged on the surface of the spray head. The protective device includes a protective cover and a positioning block. The protective cover is arranged on the surface of the spray head. The positioning block is fixedly connected to the lower surface of the spray head.

[0012] Furthermore, a clamping ball is fixedly connected to the surface of the stabilizing block. The clamping ball is clamped inside the clamping sleeve. The clamping ball is provided to facilitate the limitation of the protective cover.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, when the device is in use, the user connects the connector to the water pipe, then starts the device, rotates the pull handle to rotate the rotating pipe inside the bracket, and adjusts the nozzle up and down. When the device is in use, the user pulls the pull rod. When the pull rod moves, it drives the clamping rod to move. When the pull rod moves, it drives the first spring to displace and deform to generate elastic force. Then the clamping rod disengages from the inside of the limiting hole. Then the limiting rod loses its restraint. Then the sliding limiting rod moves out of the inside of the limiting groove. Then the rotating pipe loses its restraint. By setting the limiting device, the rotating pipe is effectively restricted, which plays a role in restricting the rotating pipe.

This improves the practicability of the device.

[0015] 2. In the present utility model, by setting the protection device, when the device is in use, the user pulls the handle, then the protective cover moves and drives the clamping sleeve to move away from the surface of the clamping ball. When the protective cover moves, it drives the connecting arm to move. When the connecting arm moves, it drives the slider to move inside the sliding groove. When the slider moves, it drives the second spring to displace and deform to generate elastic force. Then the protective cover disengages from the surface of the nozzle. Rotating the protective cover drives the connecting arm and the surface of the slider to rotate away from the surface of the nozzle. By setting the protection device, the surface of the nozzle is effectively protected, which plays a role in protecting the nozzle, reducing the situation that larger sundries easily enter the temporal part of the nozzle after the device is used, resulting in blockage and damage inside the nozzle, and improving the practicability of the device.

[0026] Specifically, a limiting hole 68 is opened on the surface of the limiting block 66. A pulling rod 69 is slidably connected to the inner wall of the pulling groove 67.

[0027] In this embodiment: By setting the pulling rod 69, the locking rod 610 can be moved, reducing the situation that the locking rod 610 is difficult to move when the device is in use.

[0028] Specifically, one end of the pulling rod 69 is fixedly connected with a locking rod 610. The locking rod 610 is slidably connected to the inner wall of the limiting hole 68. The setting of the locking rod 610 facilitates the limitation of the limiting rod 62.

[0029] Specifically, one end of the pull rod 69 is fixedly connected with a first spring 611, and the end of the first spring 611 away from the pull rod 69 is fixedly connected to the inside of the pull groove 67. The first spring 611 is provided to facilitate applying a reset elastic force to the pull rod 69.

[0030] In this embodiment: A protective device 7 is provided on the surface of the spray head 3. The protective device 7 includes a protective cover 71 and a positioning block 74. The protective cover 71 is arranged on the surface of the spray head 3. The positioning block 74 is fixedly connected to the lower surface of the spray head 3. A handle 72 is fixedly connected to the surface of the protective cover 71. A connecting arm 73 is fixedly connected to the surface of the protective cover 71. The connecting arm 73 is arranged on the inner wall of the positioning block 74. A sliding groove 75 is formed inside the positioning block 74. A slider 76 is slidably connected to the inner wall of the sliding groove 75. The connecting arm 73 is rotatably connected to the surface of the slider 76. A convex block 77 is fixedly connected to the surface of the positioning block 74. A second spring 78 is fixedly connected to the surface of the slider 76. The end of the second spring 78 away from the slider 76 is fixedly connected to the surface of the convex block 77.

[0031] In this embodiment: By providing the protective cover 71, the spray head 3 can be protected, reducing the situation that debris easily enters the inside of the spray head 3 after the equipment is used and received, resulting in blockage and damage of the spray head 3.

[0032] Specifically, a clamping sleeve 79 is fixedly connected to the upper surface of the protective cover 71, and a stabilizing block 711 is fixedly connected to the surface of the spray head 3. The clamping sleeve 79 is provided to facilitate restricting the clamping ball 710.

[0033] Specifically, a clamping ball 710 is fixedly connected to the surface of the stabilizing block 711. The clamping ball 710 is clamped inside the clamping sleeve 79. The clamping ball 710 is provided to facilitate restricting the protective cover 71.

[0034] Working principle: When the equipment is in use, the user connects the connector 1 to the water pipe, then starts the equipment, rotates the pull handle 5 to rotate the rotating pipe 4 inside the bracket 2 to adjust the spray head 3 up and down. When the equipment is in use, the user pulls the pull rod 69. When the pull rod 69 moves, it drives the clamping rod 610 to move. When the pull rod 69 moves, it drives the first spring 611 to displace and deform to generate an elastic force. Then the clamping rod 610 disengages from the inside of the limiting hole 68. Then the limiting rod 62 loses its restraint. Then the sliding limiting rod 62 moves out of the inside of the limiting groove 64. Then the rotating pipe 4 loses its restraint. By providing the limiting device 6, the rotating pipe 4 is effectively restricted, playing a role in restricting the rotating pipe 4. When the equipment is placed and transported, since the rotating pipe 4 is not restricted, during the transportation process, the rotating pipe 4 rotates randomly, easily causing the spray head 3 to collide with the connector 1, resulting in damage to the spray head 3 and difficult normal use. The practicability of the equipment is improved.

[0035] When the device is in use, the user pulls the handle 72, and then the protective cover 71 moves, driving the ferrule 79 to move away from the surface of the ball catch 710. When the protective cover 71 moves, it drives the connecting arm 73 to move. When the connecting arm 73 moves, it drives the slider 76 to move inside the chute 75. When the slider 76 moves, it drives the second spring 78 to displace and deform to generate elastic force. Then the protective cover 71 disengages from the surface of the nozzle 3. Rotating the protective cover 71 drives the connecting arm 73 and the surface of the slider 76 to rotate away from the surface of the nozzle 3. By setting the protection device 7, the surface of the nozzle 3 is effectively protected, playing a role in protecting the nozzle 3, reducing the situation that larger debris easily enters the temporal part of the nozzle 3 after the device is used, causing blockage and damage inside the nozzle 3, and improving the practicability of the device.
