Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, and more specifically, to a fire hose for firefighting. Background Technology

[0002] Utility Model Patent Application No. CN202322970351.2 discloses a fire hose for firefighting, relating to the field of fire hose technology. The application includes a bracket, with a mounting base fixedly connected to the top outer wall of the bracket. The mounting base has a U-shaped structure. A mounting box is rotatably connected to the outer wall of the mounting base on opposite sides. A rectangular opening is provided on the top outer wall of the mounting box, and two clamping seats are slidably connected to the inner wall of the rectangular opening. A fire hose is positioned between the two clamping seats. This application solves the problem that existing fire hose clamping mechanisms cannot effectively clamp the fire hose by incorporating bidirectional screw-driven clamping seats within the mounting box. The bidirectional screw itself has a self-locking function, allowing for effective and rapid fixing of the fire hose during actual use. The mounting box itself is rotatably connected, allowing for adjustment of the fire hose angle. Furthermore, a worm gear and worm are provided on the mounting box, and a handwheel on the worm allows for direct drive of the two clamping seats to press the fire hose firmly.

[0003] The aforementioned patent uses a bidirectional screw-driven clamping seat in the mounting box, and a worm gear and worm on the mounting box to drive the two clamping seats to press the water gun tightly. In use, since the fire gun is fixed on the mounting box, it can rotate on the mounting seat for angle adjustment. The clamping seats only clamp the two sides of the fire gun. When the fire gun sprays water, the water pressure is large, which may cause the firefighter to swing up and down, resulting in unstable clamping of the two clamping seats.

[0004] Therefore, we made improvements and proposed a fire hose for firefighting. Utility Model Content

[0005] The purpose of this utility model is to address the issue that the clamping seat only clamps the two sides of the fire hose, and the large water pressure when the fire hose is spraying water may cause the firefighter to swing up and down, resulting in unstable clamping by the two sides of the clamping seat.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A fire hose for firefighting, designed to improve the aforementioned problems.

[0008] The application is as follows:

[0009] The device includes a mounting frame, a support frame at the bottom of the mounting frame, a mounting block rotatably fitted on the top of the mounting frame, a fire hose body mounted on the upper side of the mounting block, a clamping assembly on the mounting block, and a fixing assembly that cooperates with the clamping assembly inside the mounting block. The clamping assembly includes two side blocks, two top blocks, and a bottom block.

[0010] By positioning the fire hose body between the two side blocks on the base block, pressing the fire hose body downwards causes the base block to move downwards. This movement, through the clamping assembly, moves the two side blocks and the top blocks on both sides towards the fire hose body. As a result, the arc-shaped clamping blocks on all four sides fit snugly against the fire hose body, clamping and fixing it around the perimeter. This reduces the likelihood of the fire hose swinging up and down due to high water pressure when spraying water, which could cause instability in the clamping seats on both sides.

[0011] As a preferred embodiment of the fire hose for fire fighting provided by this utility model, the mounting block has a through groove and a sliding groove respectively opened in the middle and on both sides, and two fixing blocks are installed on both sides of the upper part of the mounting block, and a connecting groove is opened on one side of the fixing block.

[0012] As a preferred embodiment of the fire hose provided by this utility model, the two side blocks are slidably fitted on the sliding grooves on both sides, the two top blocks are respectively located between the two fixed blocks on both sides, the bottom block is slidably fitted in the through groove, and arc-shaped clamping blocks are installed on the inner side of the two side blocks, the bottom of the two top blocks, and the upper side of the bottom block.

[0013] As a preferred embodiment of the fire hose for fire fighting provided by this utility model, both sides of the two top blocks are equipped with connecting columns that are rotatably engaged in the connecting grooves, a gear is installed in the middle of the top block, and a toothed plate that meshes with the gear is installed on the outer side of the side block, with the toothed plate located above the gear.

[0014] In a preferred embodiment of the fire hose reel provided by this utility model, a first rotating shaft is installed at the bottom of each of the two side blocks, and a connecting frame is rotatably fitted around the periphery of the first rotating shaft. A connecting block is installed at the bottom of the bottom block, and a second rotating shaft is installed on both sides of the connecting block, which rotatably fits with the other side of the connecting frame.

[0015] As a preferred embodiment of the fire hose for fire fighting provided by this utility model, the fixing component includes a limiting groove opened inside the mounting block, a retaining plate slidably fitted in the limiting groove, a through hole opened on one side of the limiting groove, and a pull rod slidably fitted in the through hole and located on the outside of the mounting block on one side of the retaining plate.

[0016] In a preferred embodiment of the fire hose reel provided by this utility model, a first spring is installed between one side of the card plate and the inner wall of the limiting groove, and a second spring is installed between the bottom of the connecting block and the bottom of the inner wall of the mounting block.

[0017] As a preferred embodiment of the fire hose for fire fighting provided by this utility model, a limiting block that slides in the limiting groove is installed on one side of the connecting block, a beveled locking block is installed on one side of the limiting block, and a locking groove that cooperates with the beveled locking block is opened on the inner side of the locking plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By placing the fire hose body between the two side blocks on the bottom block, pressing the fire hose body downward causes the bottom block to move downward. Through the clamping assembly, the two side blocks and the top blocks on both sides move towards the fire hose body, thereby making the arc-shaped clamping blocks on all four sides fit into the periphery of the fire hose body and clamp and fix it around the periphery. This reduces the situation where the fire hose swings up and down due to the high water pressure when spraying water, causing the clamping seats on both sides to be unstable.

[0034] Example 1

[0035] Please refer to Figure 1-5 A fire hose reel for firefighting includes: a mounting frame 1, a support frame 2 mounted at the bottom of the mounting frame 1, a mounting block 3 rotatably fitted on the top of the mounting frame 1, a fire hose reel body 4 mounted on the upper side of the mounting block 3, a clamping assembly 5 provided on the mounting block 3, and a fixing assembly 6 cooperating with the clamping assembly 5 inside the mounting block 3. The clamping assembly 5 includes two side blocks 501, two top blocks 502, and a bottom block 503. A through groove 8 and a sliding groove 7 are respectively formed in the middle and on both sides of the mounting block 3. Two fixing blocks 9 are mounted on both sides of the top of the mounting block 3, and a connecting groove 10 is formed on one side of each fixing block 9. The two side blocks 501 are slidably fitted on the sliding grooves 7 on both sides, the two top blocks 502 are respectively located between the two fixing blocks 9 on both sides, the bottom block 503 is slidably fitted in the through groove 8, and arc-shaped clamping blocks 504 are installed on the inner side of the two side blocks 501, the bottom of the two top blocks 502, and the upper side of the bottom block 503. Both sides of the two top blocks 502 are equipped with connecting posts 505 that rotatably engage with the connecting grooves 10. A gear 506 is installed in the middle of the top block 502. A toothed plate 507 that meshes with the gear 506 is installed on the outer side of the side block 501. The toothed plate 507 is located above the gear 506. The bottom of both side blocks 501 is equipped with a first rotating shaft 508. A connecting frame 509 is rotatably engaged with the circumference of the first rotating shaft 508. The bottom of the bottom block 503 is equipped with a connecting block 510. Both sides of the connecting block 510 are equipped with a second rotating shaft 511 that rotatably engages with the other side of the connecting frame 509.

[0036] Implementation process: The fire nozzle body 4 is positioned between the two side blocks 501 on the bottom block 503. By pressing down on the fire nozzle body 4, the bottom block 503 is slid down in the through groove 8. The fixing component 6 limits and fixes the downward movement of the bottom block 503. The downward-moving bottom block 503 drives the side blocks 501 on both sides to move towards the fire nozzle body 4 through the connecting brackets 509 on both sides. The moving side blocks 501, through the meshing of the toothed plate 507 and the gear 506, drive the top blocks 502 on both sides to rotate in the connecting groove 10 through the connecting column 505. This causes the arc-shaped clamping blocks 504 on all four sides to fit against the four sides of the fire nozzle body 4, thus clamping and fixing them around the body.

[0037] Benefits of implementation: The four curved clamping blocks 504 can fit together with the four sides of the fire hose body 4 to clamp and fix it around the body.

[0038] Example 2

[0039] The fixing component 6 includes a limiting groove 601 formed inside the mounting block 3. A retaining plate 602 is slidably fitted inside the limiting groove 601. A through hole 603 is formed on one side of the limiting groove 601. A pull rod 604, which is slidably fitted in the through hole 603 and located outside the mounting block 3, is mounted on one side of the retaining plate 602. A first spring 605 is installed between one side of the retaining plate 602 and the inner wall of the limiting groove 601. A second spring 606 is installed between the bottom of the connecting block 510 and the bottom of the inner wall of the mounting block 3. A limiting block 607, which is slidably fitted in the limiting groove 601, is mounted on one side of the connecting block 510. A beveled retaining block 608 is installed on one side of the limiting block 607. A retaining groove 609, which mates with the beveled retaining block 608, is formed on the inner side of the retaining plate 602.

[0040] Implementation process: By setting the inclined side of the inclined block 608 downward, the connecting block 510 drives the limiting block 607 to move downward in the limiting groove 601 and cooperate with the locking plate 602. The first spring 605, through its elastic force, positions the inclined block 608 in the locking groove 609. The inclined block 608, locked in the locking groove 609, limits and fixes the downward movement of the bottom block 503. The second spring 606, set between the bottom of the connecting block 510 and the bottom of the inner wall of the mounting block 3, can drive the bottom block 503 to move upward after the limiting block 607 is released, which facilitates the release of the installation and fixation of the fire hose body 4.

[0041] Benefits of implementation: It can limit and fix the downward movement of the limit block 607.
