Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and specifically relates to a fire hose fixing device. Background Technology

[0002] In firefighting operations, especially in the suppression of large-scale, multi-level fires in petrochemical plants, large warehouses, and other similar locations, it is often necessary to fix fire monitors or hoses in specific positions for continuous, directional spraying to cover critical fire points or provide cooling. Currently, common fixing methods have the following main shortcomings: 1. Most fixed brackets can only be adjusted by simple pitch or horizontal rotation, and cannot achieve rapid positioning at multiple angles in space, resulting in poor adjustment flexibility.

[0003] 2. Many fixed devices are bulky in pursuit of stability, or their support legs cannot be effectively retracted, which takes up a lot of space during transportation and storage, making them unsuitable for rapid deployment. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a fire hose fixing device to solve the problems of inflexible adjustment and poor stability of fire hoses in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A fire hose fixing device includes a mounting base, a universal adjustment structure, a column, and support legs. The mounting base and the column are connected by the universal adjustment structure. The support legs are vertically and vertically rotatable and are located at the bottom of the column, with multiple legs evenly distributed along the circumference of the column. In use, the fire hose is detachably mounted and fixed to the mounting base, and the spatial position and spray direction of the fire hose are adjusted by the universal adjustment structure.

[0006] As an improvement, the universal adjustment structure includes: a universal seat, a universal ball joint, and a clamping adjustment structure; The universal joint has a circular notch pre-reserved at the top of the spherical shell, and multiple gap slots are formed on the side wall evenly arranged along the horizontal circumference. The gap slots extend vertically from the top surface of the universal joint to the bottom of the universal joint. The bottom of the universal joint is fixed to the top of the column. The universal ball joint consists of a cylindrical rod and a ball at one end; the mounting base is fixed to the end of the cylindrical rod of the universal ball joint. The clamping adjustment structure allows the ball joint of the universal head to move within the universal seat. After the cylindrical rod of the universal head passes through the circular notch of the universal seat, the clamping adjustment structure causes the universal seat to tighten, clamping the ball joint. This facilitates adjustment of the spatial position and spray direction of the fire hose.

[0007] As an improvement, the clamping adjustment structure includes a steel wire, two nut sleeves, and a bidirectional threaded rod with knobs fixed at both ends. The universal seat portion between two adjacent gap slots is called a petal plate. Each petal plate has an ear plate fixed to its outer wall. The steel wire is connected to each ear plate in series, and nut sleeves are fixedly connected to both ends. The two nut sleeves are threaded onto the two threaded sections of the bidirectional threaded rod. Tightening the knobs causes each petal plate to clamp the ball of the universal joint. This securely clamps and fixes the universal joint.

[0008] As an improvement, the mounting base is a pipe clamp structure, fixed to the end of the cylindrical rod of the universal ball joint. This allows for easy installation and removal of the fire hose, and ensures a secure installation.

[0009] As an improvement, one end of the support leg is hinged to the side wall of the column.

[0010] This invention also includes an adjusting component, which is a cylindrical structure with a closed top and threaded holes on the top plate. The adjusting component is threaded onto the column through these holes. When flipped upwards, the free ends of each support leg parallel to the column are confined inside the adjusting component. When unfolded, the hinged ends of each support leg simultaneously abut against the bottom surface of the adjusting component. This allows for convenient height adjustment during use, and the support legs can be folded and retracted when not in use, thus reducing the space occupied by this invention.

[0011] The advantages of this utility model compared with the prior art are as follows: 1. This new type of fire hose, through the spherical mating structure of the universal ball head and universal seat, allows for continuous and stepless adjustment of the fire hose at any angle in space. Firefighters can easily adjust the hose to the optimal spray angle, greatly improving fire extinguishing efficiency.

[0012] 2. The multiple circumferentially evenly distributed support legs of this new type provide a wide support surface, ensuring overall standing stability; and the height can also be easily adjusted.

[0013] 3. After use, the support legs can be folded to reduce space occupation, making it easy to carry and store. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] like Figures 1-5 As shown, the fire hose fixing device of this utility model consists of four core parts: mounting base 1, universal adjustment structure, column 2, and support leg 3.

[0023] In this embodiment, the mounting base 1 is preferably a pipe clamp structure, the internal contour of which matches the barrel of the fire hose reel, and the fire hose reel can be firmly clamped and fixed by bolts or other fasteners. The mounting base 1 is connected to the column 2 by a universal adjustment structure, and the support legs 3 are set at the bottom of the column 2 in a flip-up manner, and five are evenly arranged along the circumference of the column 2; one end of the support leg 3 is hinged to the side wall of the column 2.

[0024] The universal adjustment structure is key to achieving spatial angle adjustment of the water gun. This structure includes a universal base 4, a universal ball joint 6, and a clamping adjustment mechanism. The universal base 4 is fixedly mounted on the top of the column 2. Its body is a spherical shell with a closed bottom and a circular notch at the top. Five evenly distributed circumferential slots 5 are machined into the sidewalls. These slots divide the lower sidewalls of the universal base 4 into five independent, flexible petal-shaped plates.

[0025] The universal ball joint 6 consists of a cylindrical rod and a ball at one end. The ball is housed within the cavity of the universal seat 4, while the cylindrical rod extends from a circular notch at the top. Through the engagement of the ball with the inner wall of the universal seat 4's spherical shell, the universal ball joint 6 can rotate in any direction; the mounting base 1 is fixed to the end of the cylindrical rod of the universal ball joint 6. The clamping adjustment structure is used to lock the universal ball head 6 after the angle has been adjusted; the clamping adjustment structure includes a steel wire 7, two nut sleeves 8 and a bidirectional threaded rod 10 with knobs 9 fixed at both ends; an ear plate 11 is fixed on the outer wall of each petal plate of the universal seat 4; a steel wire 7 passes through the holes on all the ear plates 11 in sequence to form a loop; a nut sleeve 8 is connected to each end of the steel wire 7; the two nut sleeves 8 are screwed onto the two reverse threads of the bidirectional threaded rod 10; knobs 9 are installed at both ends of the bidirectional threaded rod 10, and tightening the knobs 9 causes each petal plate to clamp the ball of the universal ball head 6.

[0026] Working principle: When the water gun angle needs to be adjusted, rotate both knobs 9 counterclockwise simultaneously. The double-threaded rod 10 rotates, causing the two nut sleeves 8 to move away from each other, thus loosening the steel wire 7. The clamping force of the steel wire 7 on the petal plate of the universal seat 4 disappears, and the petal plate slightly opens under its own elasticity. A gap appears between the universal seat 4 and the ball of the universal ball head 6. At this time, the water gun fixed on the mounting base 1 can be freely rotated to the required angle. After the angle is determined, rotate the knob 9 clockwise, and the two nut sleeves 8 move closer to each other, tightening the steel wire 7. The steel wire 7 strongly clamps all the petal plates of the universal seat 4, causing them to deform inward elastically, thereby firmly clamping the ball of the universal ball head 6 and achieving reliable locking.

[0027] Support and storage structure: Five support legs 3 are hinged to the bottom side wall of the column 2 and can be flipped up and down. The adjusting part 12 is a cylindrical part with a closed top and a threaded hole on the top plate. It is threaded onto the column 2 through the threaded hole and can rotate up and down along the column by engaging with the external thread on the column 2. When flipped up, the free ends of each support leg 3 parallel to the column 2 are restricted inside the adjusting part 12. When unfolded, the hinged ends of each support leg 3 simultaneously abut against the bottom surface of the adjusting part 12.

[0028] Deployment state: During deployment, the support legs 3 are flipped downwards and deployed until they are approximately perpendicular to the column. Then, the adjusting member 12 is screwed down from above the column until its bottom end face abuts against the root of the hinge ends of all the support legs 3. In this way, the deployment angle of the support legs 3 is limited by the adjusting member 12, and the force on them can be transmitted to the column through the hinge points and the bottom end face of the adjusting member 12, resulting in excellent stability.

[0029] Folded state: During transportation or storage, rotate the adjusting piece 12 upwards to the top of the column, then flip all the support legs 3 upwards so that their free ends (ends) gather and fit tightly against the column. Finally, unscrew the adjusting piece 12 to cover all the folded free ends of the support legs 3, thus locking them tightly against the column to form an integral rod-like structure for easy handling.

[0030] The usage process of this utility model is as follows: 1. Move the device to the predetermined position, rotate the adjusting component 12 to unfold the support leg 3, and then rotate the adjusting component 12 to lock the support leg.

[0031] 2. Fix the fire hose nozzle to the end of the universal ball joint 6 using the pipe clamp of the mounting base 1.

[0032] 3. Loosen knob 9 of the universal adjustment mechanism and adjust the water gun to the target spray angle and direction.

[0033] 4. Tighten knob 9 to lock the water gun angle.

[0034] 5. Connect the fire hose to begin the sprinkler operation.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
