Description

Technical Field

[0001] This utility model belongs to the field of indoor fire hydrant technology, specifically relating to an indoor fire hydrant with a leak-proof sealing structure. Background Technology

[0002] Indoor fire hydrants are core fire protection facilities within buildings, specifically designed to extinguish initial fires. They are a vital line of defense for protecting lives and property, and are widely distributed in public areas of various buildings such as shopping malls, office buildings, and residences. Their core components include the hydrant box, fire nozzle, hose, valve, and connectors. Some high-end models also include a fire hose reel. The box is typically red for easy identification and is marked with the words "Fire Hydrant" and usage diagrams. Installation locations strictly adhere to fire safety regulations, and are typically placed in easily accessible areas such as stairwells, corridors, and fire elevator lobbies. These locations must be unobstructed, with unobstructed access, and the water pressure must meet the water supply requirements during a fire.

[0003] Currently, existing indoor fire hydrants typically operate by rotating a disc to turn the valve stem, which then opens and closes the valve. Once opened, water is sprayed from the fire hose reel connected to the outlet pipe. However, traditional indoor fire hydrants often lack a sealing structure at the valve stem installation point, which can lead to leakage after a long period of time. This results in water waste and reduces the lifespan of the indoor fire hydrant. Utility Model Content

[0004] The purpose of this utility model is to provide an indoor fire hydrant with a leak-proof sealing structure, which aims to solve the problem that existing indoor fire hydrants, in use, usually operate by rotating a disc to turn the valve stem to open and close the valve. After opening, water will spray out from the fire hose reel connected to the outlet pipe. However, traditional indoor fire hydrants often do not have a sealing structure at the valve stem installation point, so leakage may occur at the connection point after a long time, resulting in water waste and reducing the service life of the indoor fire hydrant.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an indoor fire hydrant with a leak-proof sealing structure, comprising a fire hydrant body, an assembly flange fixedly connected to the bottom of the fire hydrant body, an installation base fixedly connected to the top of the fire hydrant body, a water outlet pipe fixedly connected to the outer wall of the fire hydrant body, and a connecting top seat connected to the top of the installation base.

[0006] A valve stem passes through the top of the connecting top seat. Bolts pass through the surfaces of the mounting seat and the connecting top seat. A nut is threaded onto the through end of the bolt. An annular protrusion is fixedly connected to the bottom of the connecting top seat. An annular groove is formed on the top of the mounting seat. An assembly groove is formed on the inner wall of the annular groove. A spring is installed inside the assembly groove. An annular rubber ring is connected to one end of the spring. An annular sealing ring is fitted onto the outer wall of the annular rubber ring.

[0007] As a preferred embodiment of the present invention, an indoor fire hydrant with a leak-proof sealing structure, the dimensions of the annular protrusion and the annular groove are matched.

[0008] As a preferred embodiment of the present invention, an indoor fire hydrant with a leak-proof sealing structure is provided with multiple springs, and the multiple springs are distributed in a ring at equal intervals.

[0009] As a preferred embodiment of the present invention, an indoor fire hydrant with a leak-proof sealing structure, the annular sealing ring can form an elastic structure with the mounting base through an annular groove, an assembly groove, a spring, and an annular rubber ring.

[0010] As a preferred embodiment of the present invention, an indoor fire hydrant with a leak-proof sealing structure is provided with an arc-shaped groove on the top of the mounting base.

[0011] As a preferred embodiment of the present invention, an indoor fire hydrant with a leak-proof sealing structure is provided with two arc-shaped grooves, which are symmetrically distributed between the two arc-shaped grooves.

[0012] As a preferred embodiment of the present invention, an indoor fire hydrant with a leak-proof sealing structure is wherein the arc-shaped groove is connected to the annular groove and the assembly groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By embedding the annular protrusion at the bottom of the connecting top seat into the annular groove at the top of the mounting seat, the annular protrusion embedded in the annular groove will push the annular sealing ring and compress the annularly distributed springs. At this time, the annular sealing ring will fit tightly against the inner wall of the annular protrusion. After passing the bolt through the mounting seat and the connecting top seat, the bolt is locked in place. In this way, the contact area between the mounting seat and the connecting top seat can be increased, and the compressed annular sealing ring can further improve the sealing effect at the connection and prevent leakage.

[0015] With symmetrically distributed arc-shaped grooves, when the annular seal needs to be removed, one end of the annular seal is located at the bottom of the arc-shaped groove. By pulling the annular seal from the arc-shaped groove, it can be easily pulled out of the annular groove and assembly groove, thus making the removal of the annular seal convenient.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: an indoor fire hydrant with a leak-proof sealing structure, including a fire hydrant body 1, an assembly flange 2 fixedly connected to the bottom of the fire hydrant body 1, an installation seat 3 fixedly connected to the top of the fire hydrant body 1, a water outlet pipe 4 fixedly connected to the outer wall of the fire hydrant body 1, and a connecting top seat 5 connected to the top of the installation seat 3.

[0026] A valve stem 6 passes through the top of the connecting top seat 5. Bolts 7 pass through the surfaces of the mounting seat 3 and the connecting top seat 5. A nut 8 is threaded onto the through end of the bolt 7. An annular protrusion 9 is fixedly connected to the bottom of the connecting top seat 5. An annular groove 10 is provided on the top of the mounting seat 3. An assembly groove 11 is provided on the inner wall of the annular groove 10. A spring 12 is installed inside the assembly groove 11. An annular rubber ring 13 is connected to one end of the spring 12. An annular sealing ring 14 is fitted onto the outer wall of the annular rubber ring 13.

[0027] Preferably, the dimensions of the annular protrusion 9 and the annular groove 10 are matched, multiple springs 12 are provided, and the multiple springs 12 are distributed in annularly at equal intervals. The annular sealing ring 14 can form an elastic structure with the mounting base 3 through the annular groove 10, the mounting groove 11, the springs 12, and the annular rubber ring 13.

[0028] In practical use, the annular protrusion 9 at the bottom of the connecting top seat 5 is embedded into the annular groove 10 at the top of the mounting seat 3. The annular protrusion 9 embedded in the annular groove 10 will push the annular sealing ring 14 and compress the annularly distributed springs 12. At this time, the annular sealing ring 14 will fit tightly against the inner wall of the annular protrusion 9. After the bolt 7 is passed through the mounting seat 3 and the connecting top seat 5, it is locked and fixed by the bolt 7. In this way, the contact area between the mounting seat 3 and the connecting top seat 5 can be increased, and the compressed annular sealing ring 14 can further improve the sealing effect at the connection and prevent leakage.

[0029] Preferably, the top of the mounting base 3 is provided with an arc-shaped groove 15. There are two arc-shaped grooves 15, and the two arc-shaped grooves 15 are symmetrically distributed. The arc-shaped grooves 15 are connected to the annular groove 10 and the assembly groove 11.

[0030] In practical use, through the symmetrically distributed arc-shaped grooves 15, when it is necessary to remove the annular sealing ring 14, one end of the annular sealing ring 14 is located at the bottom of the arc-shaped grooves 15. By pulling the annular sealing ring 14 from the arc-shaped grooves 15, the annular sealing ring 14 can be easily pulled out from the annular groove 10 and the assembly groove 11, thereby making it easy to remove the annular sealing ring 14.

[0031] Working principle: First, the fire hydrant body 1 is connected to the indoor fire water pipe using the assembly flange 2. The annular protrusion 9 at the bottom of the connecting top seat 5 is embedded into the annular groove 10 at the top of the mounting seat 3. The annular protrusion 9 embedded in the annular groove 10 pushes the annular sealing ring 14 and compresses the annularly distributed springs 12. At this time, the annular sealing ring 14 will be tightly fitted against the inner wall of the annular protrusion 9. Then, the bolt 7 is passed through the mounting seat 3 and the connecting top seat 5 and locked in place using the bolt 7. In this way, the contact area between the mounting seat 3 and the connecting top seat 5 can be increased, and the compressed annular springs 12 can be used to further enhance the sealing effect. The sealing ring 14 can further improve the sealing effect at the connection and prevent leakage. At this time, the valve inside the fire hydrant body 1 can be opened and closed by rotating the valve stem 6 by rotating the disc. When the annular sealing ring 14 needs to be replaced later, the mounting seat 3 can be separated from the connecting top seat 5 by removing the bolts 7 and nuts 8. Since one end of the annular sealing ring 14 is located at the bottom of the arc groove 15, the annular sealing ring 14 can be easily pulled out from the annular groove 10 and the assembly groove 11 by pulling the annular sealing ring 14 from the arc groove 15, thus making it easy to remove the annular sealing ring 14.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
