Description

Technical Field

[0001] This utility model relates to the field of fire-fighting foam gun technology, specifically a fire-fighting foam gun with an angle-adjustable structure. Background Technology

[0002] Firefighting foam guns are mainly composed of a barrel, handwheel, gun body, ball valve, suction pipe, and KY65 threaded connector or island connector. They can generate and spray air foam for extinguishing Class A, B, and C liquid fires or spray water for extinguishing general solid fires.

[0003] According to a fire foam gun with adjustable angle (Announcement No.: CN209033614U), the aforementioned application uses a rotating rod, bearing, and rotating cylinder to adjust the direction of the fire foam gun up, down, left, and right. This not only saves the physical strength of firefighters but also achieves all-round fire extinguishing without blind spots, thus increasing the fire extinguishing range of the fire foam gun.

[0004] However, in actual use, although the above-mentioned equipment can adjust the direction of the fire foam gun up, down, left, and right through the rotating rod, bearing, and rotating drum, it may be necessary to spray at a fixed point or to set up an additional fixed spray gun when spraying foam for firefighting. In this case, it is not conducive to the operation of firefighters. In view of this, we propose a fire foam gun with an angle adjustment structure. Utility Model Content

[0005] The purpose of this invention is to provide a fire-fighting foam gun with an angle-adjustable structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting foam gun with an angle-adjustable structure, comprising a mounting plate, a rotating disk rotatably mounted on the outer wall of the mounting plate, a mounting rod fixedly connected to the outer wall of the rotating disk, a foam gun assembly disposed on the inner wall of the mounting rod, an external valve port disposed on the outer wall of the foam gun assembly, an adjustment assembly disposed on the outer wall of the mounting rod, the adjustment assembly comprising a side frame, the side frame fixedly connected to the outer wall of the mounting rod, a side shell fixedly connected to the outer wall of the side frame, a base plate fixedly connected to the inner wall of the side shell, and a threaded rod rotatably mounted on the inner wall of the base plate;

[0007] A threaded slider is threadedly connected to the outer wall of a threaded rod. A U-shaped frame is fixedly connected to the outer wall of the threaded slider. An installation block is fixedly connected to the end of the U-shaped frame. A rotating rod is rotatably mounted on the outer wall of the installation block. A sponge sleeve is fixedly connected to the outer wall of the rotating rod.

[0008] Preferably, the center line of the mounting plate is on the same straight line as the center line of the rotating plate and the center line of the mounting rod.

[0009] Preferably, the number of rotating rods is two sets, and the two sets of rotating rods are arranged on both sides mirroring the center plane of the mounting block.

[0010] Preferably, the end of the threaded rod is rotatably mounted on the inner wall of the side shell, and the outer wall of the threaded rod is adapted to the inner wall of the side shell.

[0011] Preferably, the bottom end of the base plate is provided with a pressing component, the pressing component includes a vertical plate, the vertical plate is fixedly connected to the bottom end of the base plate, the outer wall of the vertical plate is fixedly connected to an elastic telescopic plate, the end of the elastic telescopic plate is fixedly connected to a pressure sleeve, the outer wall of the pressure sleeve is fixedly connected to a movable rough block, and the outer wall of the threaded rod is fixedly connected to a fixed rough block.

[0012] Preferably, the number of fixed rough blocks is several, and the several fixed rough blocks are arranged in a circumferential array on the outer wall of the threaded rod.

[0013] Preferably, the centerline of the elastic telescopic plate and the centerline of the pressure sleeve are on the same straight line, so that the elastic telescopic plate can apply pressure to the pressure sleeve.

[0014] Compared with the prior art, this utility model provides a fire foam gun with an angle adjustment structure, which has the following beneficial effects:

[0015] 1. This fire foam gun with an angle-adjustable structure can be mounted on the vehicle body with bolts during normal use. The pipeline can be connected via an external valve port to spray foam for fire extinguishing. The angle can be adjusted left or right by rotating the rotating disc, and the angle can be adjusted up or down by rotating the threaded rod. This causes the limited threaded slider to move the mounting block on the U-shaped frame, raising or lowering the rear end of the foam gun assembly as the two sets of rotating rods and the foam sleeve move, thus adjusting the spray angle. After adjusting the angle, the foam gun assembly does not need to be constantly held; multiple guns can be quickly set up by a single person, saving setup time and manpower requirements, and facilitating better fire rescue operations.

[0016] 2. This fire foam gun with an angle adjustment structure can release the compressed elastic telescopic plate after rotating the threaded rod, allowing the pressure sleeve and the moving rough block to move forward. This allows the moving rough block to rub against the fixed rough block on the threaded rod, making the threaded rod more stable and preventing it from rotating off-center due to water flow interference. This also further improves the overall practicality. Attached Figure Description

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a fire foam gun with an angle adjustment structure, including a mounting plate 1, a rotating plate 2 rotatably mounted on the outer wall of the mounting plate 1, a mounting rod 3 fixedly connected to the outer wall of the rotating plate 2, a foam gun assembly 4 provided on the inner wall of the mounting rod 3, an external valve port 5 provided on the outer wall of the foam gun assembly 4, and an adjustment component 6 provided on the outer wall of the mounting rod 3. The adjustment component 6 includes a side frame 601, which is fixedly connected to the outer wall of the mounting rod 3. A side shell 602 is fixedly connected to the outer wall of the side frame 601, and a base plate 603 is fixedly connected to the inner wall of the side shell 602. A threaded rod 604 is rotatably mounted on the inner wall of the base plate 603.

[0025] Furthermore, the threaded slider 605 is threadedly connected to the outer wall of the threaded rod 604. A U-shaped frame 606 is fixedly connected to the outer wall of the threaded slider 605. An installation block 607 is fixedly connected to the end of the U-shaped frame 606. A rotating rod 608 is rotatably mounted on the outer wall of the installation block 607. A sponge sleeve 609 is fixedly connected to the outer wall of the rotating rod 608.

[0026] In the embodiments of this utility model, the center line of the mounting plate 1, the center line of the rotating plate 2, and the center line of the mounting rod 3 are all on the same straight line. There are two sets of rotating rods 608, and the two sets of rotating rods 608 are mirror images of the center plane of the mounting block 607 on both sides. The end of the threaded rod 604 is rotatably mounted on the inner wall of the side shell 602, and the outer wall of the threaded rod 604 is adapted to the inner wall of the side shell 602.

[0027] Furthermore, a pressure-contacting component 7 is provided at the bottom end of the base plate 603. The pressure-contacting component 7 includes a vertical plate 701, which is fixedly connected to the bottom end of the base plate 603. An elastic telescopic plate 702 is fixedly connected to the outer wall of the vertical plate 701. A pressure sleeve 703 is fixedly connected to the end of the elastic telescopic plate 702. A movable rough block 704 is fixedly connected to the outer wall of the pressure sleeve 703. A fixed rough block 705 is fixedly connected to the outer wall of the threaded rod 604. The number of fixed rough blocks 705 is several, and the several fixed rough blocks 705 are arranged in a circumferential array on the outer wall of the threaded rod 604. The center line of the elastic telescopic plate 702 and the center line of the pressure sleeve 703 are on the same straight line, so that the elastic telescopic plate 702 can apply pressure to the pressure sleeve 703.

[0028] In this invention, during daily use, the mounting plate 1 can be bolted onto the vehicle body to be erected. When in use, the pipeline can be connected through the external valve port 5 to spray foam for fire extinguishing. When the left and right angles need to be adjusted, the angle can be adjusted by rotating the rotating plate 2. When adjusting the up and down angles, the threaded rod 604 can be rotated, so that the limited threaded slider 605 can drive the mounting block 607 on the U-shaped frame 606 to move. This allows the rear end of the foam gun assembly 4 to be raised or lowered when the two sets of rotating rods 608 and the sponge sleeve 609 are moved, thereby adjusting the spray angle up and down. After adjusting the angle, it is not necessary to hold the foam gun assembly 4 continuously. Multiple spray guns can be quickly set up by a single person, saving erection time and manpower requirements, and facilitating better fire rescue.

[0029] After rotating the threaded rod 604, the compressed elastic telescopic plate 702 can be released, allowing the pressure sleeve 703 and the moving rough block 704 to move forward. This allows the moving rough block 704 to rub against and contact the fixed rough block 705 on the threaded rod 604, enabling the threaded rod 604 to maintain better stability and preventing rotational deviation due to water flow interference. This also further improves the overall practicality.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
