Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a fire hydrant casting with good stability. Background Art

[0002] Fire hydrants are important firefighting components in firefighting systems. They are mainly used by fire trucks to draw water from municipal water supply networks or outdoor firefighting water supply networks to extinguish fires. They can be directly connected to water hoses and water guns to discharge water for firefighting. Fire hydrant systems are also one of the important firefighting facilities for fighting fires, providing effective protection for the safety of people's lives and property. Fire hydrant castings, as the factory initial parts of fire hydrants, are the basis for the subsequent installation and use of fire hydrant components.

[0003] Existing fire hydrants adopt a casting structure. Since the fire hydrant casting is exposed on the ground, the underground part is directly connected to the water inlet network, so when it is hit by an object, it is easy to cause the connection between the two to be disconnected, resulting in water overflow.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fire hydrant casting with good stability is proposed. Utility Model Content

[0005] The utility model aims to provide a fire hydrant casting with good stability to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire hydrant casting with good stability, comprising a bolt body and a protective assembly, a lower guide seat is fixed at the lower part of the outside of the bolt body, the protective assembly is arranged on the outside of the bolt body, and the protective assembly comprises a fixed cylinder, a sliding rod, a slider, a first spring, a connecting rod, a protective plate, a spring damper and an upper guide seat, a sliding rod is arranged at the groove on the surface of the fixed cylinder, and a slider is slidingly arranged on the outside of the sliding rod, a first spring is connected between the sliders, and a connecting rod is connected to the middle part of the slider through a rotating shaft, the other end of the connecting rod is connected to the protective plate through a rotating shaft, and a spring damper is installed on a side of the protective plate close to the fixed cylinder, and the upper guide seat is fixed on the upper part of the outside of the bolt body.

[0007] Furthermore, the fixing tube and the sliding rod are fixedly connected, and the first spring is sleeved on the outside of the sliding rod.

[0008] Furthermore, the upper guide seat and the lower guide seat are parallel to each other, and the protective plate passes through the holes on the surfaces of the upper guide seat and the lower guide seat.

[0009] Furthermore, the protective plate has an arc-shaped structure, and four protective plates are provided.

[0010] Furthermore, the output end of the plug body is connected to a water outlet pipe, and a connecting ring is installed on the left side inside the water outlet pipe.

[0011] Furthermore, a connecting pipe is fixedly passed through the middle of the connecting ring, and a hook is connected to the inside of the water outlet pipe via a pin.

[0012] Furthermore, a second spring is provided on a side of the hook away from the transverse center axis of the connecting pipe, and the hook is elastically connected to the water outlet pipe through the second spring.

[0013] The utility model provides a fire hydrant casting with good stability, which has the following beneficial effects:

[0014] 1. When the bolt body is hit, the object first contacts the protective plate, causing the protective plate to move toward the bolt body along the holes on the surfaces of the upper guide seat and the lower guide seat, thereby changing the angle of the connecting rod on the protective plate and the slider, so that the slider squeezes the first spring through the support of the connecting rod, and the elastic force provided by the first spring and the spring damper achieves a force dissipation effect, thereby ensuring the stability of the bolt body.

[0015] 2. The utility model inserts the hose connector at the end of the fire hose into the water outlet pipe, so that the hose connector slides into the slot of the hook along the inclined surface of the hook and fits into the outer wall of the pipe, so that the hose connector and the hook are engaged when the second spring is reset, avoiding the hose connector from falling off during the pulling process.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 and Figure 3As shown, a fire hydrant casting with good stability includes a bolt body 1 and a protective assembly 3. A lower guide seat 2 is fixed below the outside of the bolt body 1. The protective assembly 3 is arranged on the outside of the bolt body 1, and the protective assembly 3 includes a fixed cylinder 301, a slide bar 302, a slider 303, a first spring 304, a connecting rod 305, a protective plate 306, a spring damper 307 and an upper guide seat 308. The slide bar 302 is arranged at the groove on the surface of the fixed cylinder 301, and the slider 303 is slidably arranged outside the slide bar 302. The first spring 304 is connected between the sliders 303, and the middle of the slider 303 is connected to the first spring 304. A connecting rod 305 is connected through the rotating shaft, and the other end of the connecting rod 305 is connected to a protective plate 306 through the rotating shaft, and a spring damper 307 is installed on the side of the protective plate 306 close to the fixed cylinder 301, the upper guide seat 308 is fixed on the upper outside of the bolt body 1, the fixed cylinder 301 and the sliding rod 302 are fixedly connected, the first spring 304 is sleeved on the outside of the sliding rod 302, the upper guide seat 308 and the lower guide seat 2 are parallel to each other, the protective plate 306 passes through the holes on the surface of the upper guide seat 308 and the lower guide seat 2, the protective plate 306 has an arc-shaped structure, and four protective plates 306 are provided.

[0022] The specific operation is as follows: when the bolt body 1 is hit, the object first contacts the protective plate 306, causing the protective plate 306 to move toward the bolt body 1 along the holes on the surfaces of the upper guide seat 308 and the lower guide seat 2, thereby changing the angle of the connecting rod 305 on the protective plate 306 and the slider 303, so that the slider 303 squeezes the first spring 304 through the support of the connecting rod 305, and the force dissipation effect is achieved through the elastic force provided by the first spring 304 and the spring damper 307, thereby ensuring the stability of the bolt body 1.

[0023] like Figure 2 As shown, the output end of the bolt body 1 is connected to a water outlet pipe 4, and a connecting ring 5 is installed on the left side inside the water outlet pipe 4, a connecting pipe 6 is fixed through the middle of the connecting ring 5, and a hook 8 is connected to the inside of the water outlet pipe 4 through a pin shaft 7. A second spring 9 is provided on the side of the hook 8 away from the transverse center axis of the connecting pipe 6, and the hook 8 is elastically connected to the water outlet pipe 4 through the second spring 9.

[0024] The specific operation is as follows: insert the water hose connector at the end of the fire hose into the water outlet pipe 4, so that the water hose connector slides into the groove of the hook 8 along the inclined surface of the hook 8 and fits against the outer wall of the connecting pipe 6, so that the water hose connector and the hook 8 form a snap fit when the second spring 9 is reset, to prevent the water hose connector from falling off during the pulling process.

[0025] In summary, when the fire hydrant casting with good stability is used, first, four protective plates 306 distributed in an annular manner with equal distance form a fence around the bolt body 1. When an object collides with the bolt body 1, the object first contacts the protective plate 306. At this time, the protective plate 306 is forced to move along the holes on the surfaces of the upper guide seat 308 and the lower guide seat 2 toward the bolt body 1, causing the connecting rod 305 to rotate on the slider 303. The slider 303 is driven by the connecting rod 305 to slide on the slide bar 302 to squeeze the first spring 304, so that the first spring 304 stores elastic potential energy and cooperates with the spring damper 307 on the outside of the fixed cylinder 301 to achieve the effect of offsetting the impact force, thereby improving the stability of the bolt body 1 and ensuring a reliable connection between the underground part and the water inlet network.

[0026] When water is needed to extinguish a fire, the hose connector at the end of the fire hose can be inserted into the water outlet pipe 4, so that the hose connector slides into the slot of the hook 8 along the inclined surface on the right side of the hook 8 and relies on the second spring 9 to reset and engage with the hook 8, and fit with the outer wall of the connecting pipe 6, so that the connection is quick and convenient, meeting the use requirements in emergency situations.
