Description

Technical Field

[0001] The utility model relates to the technical field of fire hose reels, in particular to a fire hose reel with adjustable belt unwinding speed. Background Art

[0002] Fire hose reels are widely used in firefighting. In the early stages of a fire, fire hose reels provide a convenient means of extinguishing it. They allow non-professional firefighters to quickly initiate firefighting operations, control the spread of the fire, and buy valuable time for professional firefighters. For example, in shopping malls, office buildings, hotels, and other places, workers or ordinary citizens can use fire hose reels to extinguish fires as soon as they occur, minimizing the damage caused by the fire. Fire hose reels are constructed by wrapping a water pipe or hose around a drum. In the event of a fire, pulling the hose causes the drum to rotate, allowing the hose to be pulled to the fire site. The other end of the hose is connected to an external water inlet, allowing ordinary people to quickly extinguish fires using the fire hose reel.

[0003] A rotary joint is a connection device that enables the transfer of media during rotation. It typically consists of a sealing structure, a rotating component, and a stationary component. The sealing structure prevents leakage of media during rotation. As the rotating and stationary components rotate relative to each other, the rotary joint allows media to be transferred between different pipes or equipment. For example, in some industrial production lines, a rotary joint connects a rotating drum with a stationary pipe, enabling functions such as heating or cooling the drum's interior or conveying materials.

[0004] However, the force required to pull out the fire hose of the existing fire hose reel is pre-set. If the force for pulling out the fire hose is set too large, it will be difficult for women with less strength to use the fire hose. If the initial force is set too small, the fire hose will easily fall off the fire hose reel, causing the hose to scatter. At the same time, children can also pull the fire hose and use the fire hose reel to play, causing unnecessary fire damage. After the fire hose reel is used, water in the hose will accumulate in the hose, making the hose heavy and difficult to wind back onto the drum. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] See also Figure 1-Figure 5A fire hose reel with adjustable belt unwinding speed comprises: a drum 1 and a hanging bracket 8, a rotary joint 9 is fixedly connected to the hanging bracket 8, a drum 1 is fixedly sleeved on the rotating end of the rotary joint 9, a fire hose 2 is wound around the drum 1, a T-shaped block 3 is fixedly connected to the drum 1, a slot 31 is provided in the T-shaped block 3, a partition 32 is fixedly connected to the slot 31, a limit block 4 is slidably arranged in the partition 32, the top of the limit block 4 is connected to a slider 6 slidably arranged in the slot 31 through a spring 5, one end of the spring 5 is fixedly connected to the top of the limit block 4, and the other end of the spring 5 is fixedly connected to the It is connected to the bottom of the slider 6 to provide elastic force for the limit block 4 to squeeze the fire hose 2. A screw 7 is threaded on the T-shaped block 3, and the bottom of the screw 7 is against the slider 6. The water outlet end of the fire hose 2 passes through the slot 31, and the bottom of the limit block 4 is squeezed on the fire hose 2. The water inlet end of the fire hose 2 is fixedly connected to the water outlet end of the rotary joint 9. One end of the rotary joint 9 fixed on the hanging bracket 8 is provided with a water inlet, and is fixedly connected to the water inlet pipe 10. The water source is provided to the fire hose 2 through the water inlet pipe 10, and the hanging bracket 8 is fixed to the external wall by screws.

[0026] Specifically, the present invention changes the compression degree of the spring 5 by turning the screw 7, thereby changing the elastic force of the spring 5, so that the squeezing force of the limit block 4 on the fire hose 2 can be adjusted, thereby changing the size of the force required to pull the fire hose 2, and realizing that the release speed of the fire hose 2 can be changed under the same pulling force. Similarly, by adjusting the squeezing force of the limit block 4 on the fire hose 2, it is possible to save more effort when pulling out the fire hose 2 at the same speed. When the hose is not in use, the squeezing force of the limit block 4 on the fire hose 2 is increased, and the water in the hose can be squeezed out and the water outlet end of the hose can be fixed when the hose is retracted, preventing children from pulling out the hose to play.

[0027] Furthermore, the bottom of the limit block 4 is fixedly connected to a stop block 41 , the limit block 4 is located on the top of the partition 32 , the stop block 41 is slidably set in the partition 32 , and the bottom of the stop block 41 passes through the partition 32 and is squeezed on the fire hose 2 .

[0028] Specifically, refer to Figure 3 and Figure 4 Under the action of the elastic force of the spring 5, the block 41 is pressed against the partition 32, and the block 41 passes through the partition 32 to squeeze the fire hose 2. When the fire hose 2 is pulled outward, the fire hose 2 needs to overcome the squeezing force of the block 41 on the fire hose 2 before it can be pulled out, that is, the block 41 overcomes the elastic force of the spring 5 and slides upward in the partition 32.

[0029] Furthermore, a sliding groove 311 is defined in the card slot 31 . The sliding groove 311 is located above the partition 32 , and the slider 6 is slidably disposed in the sliding groove 311 .

[0030] Specifically, refer to Figure 4 By opening a slide groove 311 in the card slot 31 and sliding the slider 6 in the slide groove 311, when the screw 7 is rotated upward or downward, under the elastic force of the spring 5, the screw 7 drives the slider 6 to slide upward or downward more stably, so that the elastic force of the spring 5 changes more accurately with the elastic deformation of the spring 5.

[0031] Furthermore, the bottom of the stopper 41 is rounded.

[0032] Specifically, refer to Figure 4 By rounding the bottom of the stop block 41 , the wear between the fire hose 2 and the stop block 41 when the fire hose 2 slides in the slot 31 can be reduced, thereby extending the service life of the fire hose 2.

[0033] Furthermore, an anti-slip sleeve 71 is fixedly sleeved on the top of the screw 7 .

[0034] Specifically, refer to Figure 1 By fixing the anti-slip sleeve 71 on the top of the screw 7, the friction between the user's hand and the screw 7 is increased, which makes it easier for the user to adjust the elastic force of the spring 5 and change the difficulty of pulling the fire hose 2 out of the drum 1.

[0035] Furthermore, the outer sides of the T-shaped block 3, the limiting block 4, the stop block 41, the spring 5, the slider 6, and the screw 7 are all provided with a waterproof coating.

[0036] Specifically, since the water outlet end of the fire hose 2 is limited in the slot 31, it is often in contact with water and is more susceptible to corrosion than other areas of the equipment. By brushing waterproof paint on the outside, the corrosion resistance of the T-shaped block 3, the limit block 4, the stop block 41, the spring 5, the slider 6, and the screw 7 is improved.

[0037] In this utility model, reference is made to Figures 1 to 5 First, by turning the screw 7 upward, the slider 6 slides upward in the slide groove 311. At this time, the elastic deformation of the spring 5 is reduced, and the elastic force applied by the spring 5 on the limit block 4 will be reduced, thereby reducing the force required to pull out the fire hose 2, which can be used more conveniently by users with less strength. Similarly, if the user himself is strong, the speed of pulling out the fire hose 2 will be faster than when the elastic force of the spring 5 is not adjusted; after the fire is extinguished, the hose is retracted by rotating the drum 1, and the squeezing effect of the block 41 on the fire hose 2 squeezes out the residual water in the fire hose 2, making it easier to store the hose.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
