Description
Technical Field
[0001] This utility model relates to the field of fire protection technology, and in particular to a fire hydrant box that is easy to connect. Background Technology
[0002] Fire hydrant boxes are commonly used in fire emergencies. They allow firefighters to quickly connect fire hoses in an emergency, saving valuable time. Whether dealing with building fires, factory fires, or emergencies in public places, they can ensure efficient firefighting, reduce fire losses, and protect lives and property.
[0003] In practice, existing fire hydrant boxes, through the coordinated use of fire hoses, quick-connect clips, and fire hydrants, are capable of emergency response to fires and rapid extinguishing of the fire source. However, the following shortcomings still exist during use:
[0004] After the fire hose and fire hydrant connector are connected, when the valve is opened to allow water flow, water leakage will occur due to the limited space for movement in the connection structure. This will lead to a drop in fire water pressure, a reduction in the distance and intensity of the water gun spray, and an inability to accurately and effectively cover the fire source. Therefore, this application provides a fire hydrant box that is easy to connect to meet the requirements. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fire hydrant box that is easy to connect.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fire hydrant box that is easy to connect, including a fire hydrant box shell, wherein a fire hose and a fire hydrant head are provided in the inner cavity of the fire hydrant box shell, and a snap-fit component is provided at one end of the fire hose;
[0007] The snap-fit assembly includes a connecting tube, a first fixing rod rotatably connected to the side of the connecting tube, a first sleeve provided at the bottom of the first fixing rod, a first fixing ring fixedly connected to the bottom of the first sleeve, a slider fixedly connected to the side of the inner cavity of the first sleeve, a guide groove and a first groove provided on the side of the first fixing ring, one end of the slider extending into the inner cavity of the guide groove, and one end of the slider slidably connected to the inner cavity of the guide groove.
[0008] In a preferred embodiment, a spring piece is fixedly connected to the top of the first fixing ring, and the end of the spring piece away from the first fixing ring is fixedly connected to the bottom of the first sleeve. A second groove is formed on the outer surface of the connecting tube.
[0009] The technical effect of adopting the above technical solution is that by setting a spring, the first sleeve can be reset, and by setting a second groove, the position of the first groove can be fixed.
[0010] In a preferred embodiment, a sealing ball is provided in the inner cavity of the first groove.
[0011] The technical effect of adopting the above technical solution is that the connection between the connecting pipe and the first sleeve can be sealed by the cooperation of the first groove and the sealing ball.
[0012] In a preferred embodiment, the outer surface of the second fixing ring is provided with a sliding groove, the top of the second sleeve is provided with a limiting groove, and a telescopic block is slidably connected to the side of the second sleeve.
[0013] The technical effect of adopting the above technical solution is that by setting the shape of the limiting groove to a certain angle, the telescopic block can be extended outward. Through the cooperation of the telescopic block and the sliding groove, the position of the connecting pipe and the first sleeve can be fixed.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] The outer surface of the first sleeve is slidably connected to the inner wall of the first fixing ring. A certain gap is provided at the top of the first sleeve, allowing water to be transmitted to the sprinkler head via a fire hose. A fire hydrant head allows water to be quickly drawn out. Manually pushing the connecting pipe downwards along the inner cavity of the first sleeve causes the first fixing rod to move downwards along the inner cavity of the guide groove. When the first fixing rod reaches a certain position, its bottom contacts the top of the slider. Continuing to push the connecting pipe further causes the slider to move the first sleeve downwards. As the first sleeve moves downwards, it compresses the spring. When the first sleeve reaches a certain position, the gap at the top of the first sleeve is level with the first groove, and simultaneously, the connecting pipe and the sealing ring... When one side of the sealing ball contacts the slider, it can push the sealing ball a certain distance along the inner cavity of the first groove. At this time, rotating the first fixing rod clockwise can cause the first fixing rod to slide along the inner cavity of the guide groove. When the first fixing rod loses contact with the slider, the spring releases the stress, which can cause the slider to move upward. When the slider moves upward, the inner wall of the first sleeve squeezes the sealing ball back into place along the inner cavity of the first groove, so that the sealing ball falls into the inner cavity of the second groove, thereby achieving the effect of sealing the inside of the connection and preventing water leakage when the water flow is turned on. At the same time, during the downward movement of the connecting pipe, the guide groove and the slider cooperate to limit the movement trajectory of the first sleeve, preventing the position from deviating during pushing and causing damage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 2-5 As shown, this embodiment provides a technical solution: a fire hydrant box that is easy to connect, including a fire hydrant box shell 1, the inner cavity of the fire hydrant box shell 1 is provided with a fire hose 11 and a fire hydrant head 12, and one end of the fire hose 11 is provided with a snap-fit component 2;
[0027] The snap-fit assembly 2 includes a connecting tube 21, a first fixing rod 22 rotatably connected to the side of the connecting tube 21, a first sleeve 23 provided at the bottom of the first fixing rod 22, a first fixing ring 24 fixedly connected to the bottom of the first sleeve 23, a slider 25 fixedly connected to the side of the inner cavity of the first sleeve 23, a guide groove 26 and a first groove 27 formed on the side of the first fixing ring 24, one end of the slider 25 extending into the inner cavity of the guide groove 26 and slidably connected to the inner cavity of the guide groove 26, a spring piece 29 fixedly connected to the top of the first fixing ring 24, and the end of the spring piece 29 away from the first fixing ring 24 fixedly connected to the bottom of the first sleeve 23. The outer surface of the pipe 21 is provided with a second groove 210, and the inner cavity of the first groove 27 is provided with a sealing ball 28. The outer surface of the first sleeve 23 is slidably connected to the inner wall of the first fixing ring 24. A certain gap is provided at the top of the first sleeve 23. By setting the fire hose 11, water can be transmitted to the sprinkler head. By setting the fire hydrant head 12, water can be quickly led out. In use, firstly, manually align the connecting pipe 21 with the inner cavity of the first sleeve 23 and push it downward. When the connecting pipe 21 moves downward, it can drive the first fixing rod 22 to move downward along the inner cavity of the guide groove 26. When the first fixing rod 22 moves to a certain position, the first fixing... The bottom of the fixed rod 22 contacts the top of the slider 25, continuing to push the connecting tube 21, thereby driving the first sleeve 23 downward through the slider 25. When the first sleeve 23 moves downward, it can cause the spring 29 to be compressed. When the first sleeve 23 moves to a certain position, the gap at the top of the first sleeve 23 is at the same level as the first groove 27. At the same time, the connecting tube 21 contacts one side of the sealing ball 28, thereby pushing the sealing ball 28 out a certain distance along the inner cavity of the first groove 27. At this time, rotating the first fixed rod 22 clockwise can cause the first fixed rod 22 to slide along the inner cavity of the guide groove 26. When the first When the fixed rod 22 loses contact with the slider 25, the spring 29 releases stress, which causes the slider 25 to move upward. When the slider 25 moves upward, the inner wall of the first sleeve 23 pushes the sealing ball 28 back into place along the inner cavity of the first groove 27, so that the sealing ball 28 falls into the inner cavity of the second groove 210, thereby achieving the effect of sealing the inside of the connection and preventing water leakage when the water flow is turned on. At the same time, during the downward movement of the connecting pipe 21, the guide groove 26 and the slider 25 cooperate with each other to limit the movement trajectory of the first sleeve 23, preventing the position from deviating during pushing and causing damage.
[0028] Going further, such as Figures 3-5As shown: A fixing component 3 is provided at the top of the connecting pipe 21. The fixing component 3 includes a second sleeve 31. A second fixing ring 32 is fixedly connected to the top of the first sleeve 23. A sliding groove 33 is formed on the outer surface of the second fixing ring 32. A limit groove 36 is formed at the top of the second sleeve 31. A telescopic block 34 is slidably connected to the side of the second sleeve 31. After the connecting pipe 21 moves to a certain position along the inner cavity of the first sleeve 23, rotating the connecting pipe 21 clockwise will drive the second sleeve 31 to rotate. When the second sleeve 31 rotates, it can... The limiting rod 35 moves along the inner cavity of the limiting groove 36, thereby driving the telescopic block 34 to move. By setting the shape of the limiting groove 36 at a certain angle, the telescopic block 34 can be made to unfold outward. When the second sleeve 31 rotates to a certain position, the telescopic block 34 slides into the inner cavity of the slide groove 33, thereby fixing the position of the connecting pipe 21 and the first sleeve 23, thus preventing the connection between the connecting pipe 21 and the first sleeve 23 from falling off due to the impact of water flow.
[0029] During use, after fixing, when water flow is connected, the pressure from the water flow impact will concentrate at the connection between the slide groove 33 and the telescopic block 34, causing the telescopic block 34 to deform or be damaged. Figure 5 As shown: The top of the telescopic block 34 is fixedly connected to a limiting rod 35. One end of the limiting rod 35 extends into the inner cavity of the limiting groove 36. The other end of the limiting rod 35 is slidably connected to the inner cavity of the limiting groove 36. There are two limiting rods 35 and two limiting grooves 36. The two limiting rods 35 and the two limiting grooves 36 are located at the top of the connecting pipe 21 and the bottom of the second sleeve 31, respectively. When subjected to water flow impact, the stress generated by the impact is transmitted to the limiting rod 35 through the telescopic block 34. Through the cooperation of the limiting rod 35 and the limiting groove 36, the impact force can be distributed more evenly on the snap-fit structure, avoiding the problem of excessive local stress leading to structural damage.
[0030] Working principle:
[0031] like Figure 1-5 As shown:
[0032] In use: First, unfold the fire hose 11, then align the connecting pipe 21 with the inner cavity of the first sleeve 23 and push it downwards. When the connecting pipe 21 moves downwards, it can drive the first fixing rod 22 to move downwards along the inner cavity of the guide groove 26. When the first fixing rod 22 reaches a certain position, the bottom of the first fixing rod 22 contacts the top of the slider 25. At this time, continue to push the connecting pipe 21, so that the slider 25 can drive the first sleeve 23 to move downwards. When the first sleeve 23 reaches a certain position, the gap at the top of the first sleeve 23 is at the same level as the first groove 27, and at the same time, the connecting pipe 21 contacts one side of the sealing ball 28, so that the sealing ball 28 can be pushed out a certain distance along the inner cavity of the first groove 27. At this time, by rotating the first fixing rod 22 clockwise, the first fixing rod 22 can be slid along the inner cavity of the guide groove 26. When the first fixing rod 22 contacts the sliding ball 25, the first fixing rod 22 slides down along the inner cavity of the guide groove 26. When block 25 loses contact, spring 29 releases stress, which causes slider 25 to move upward. When slider 25 moves upward, the inner wall of first sleeve 23 pushes sealing ball 28 back into position along the inner cavity of first groove 27, so that sealing ball 28 falls into the inner cavity of second groove 210, thereby achieving the effect of sealing the inside of the connection. At the same time, when connecting pipe 21 rotates clockwise, it can drive second sleeve 31 to rotate. When second sleeve 31 rotates, it can cause limit rod 35 to move along the inner cavity of limit groove 36, thereby achieving the effect of driving telescopic block 34 to move. When second sleeve 31 rotates to a certain position, telescopic block 34 slides into the inner cavity of slide groove 33. After the connecting pipe 21 and first sleeve 23 are fixed by snapping, the nozzle is snapped to the other end of fire hose 11, and then the fire hydrant head 12 is opened and aimed at the fire source for fire extinguishing.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
