Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, and in particular to a fire hydrant rotary interface. Background Technology

[0002] The main function of fire hydrants is to control combustibles, isolate oxidizers, and eliminate ignition sources. They are divided into indoor fire hydrants and outdoor fire hydrants. Fire hydrants with rotating interfaces are called rotating fire hydrants. Specifically, they are indoor fire hydrants whose bodies can rotate 360 ​​degrees horizontally relative to the base connected to the water inlet pipe, thereby adjusting the angle of the interface.

[0003] Patent publication number CN216092016U discloses a rotatable indoor fire hydrant, comprising a hydrant body, a sealing cover mounted on the upper surface of the hydrant, a rotating handle movably connected to the upper surface of the sealing cover, an interface on the side surface of the hydrant body, and a rotating mechanism at the bottom of the hydrant body. Through the rotating mechanism, a mounting base is used for positioning and connecting with a water pipe, and a positioning seat is fixed to the hydrant body. Rollers arranged according to usage requirements allow the positioning seat to rotate on the mounting base surface, thus giving the fire hydrant the advantage of rotatability. This solves the problem of existing indoor fire hydrants lacking rotatability, facilitating use in emergencies and greatly improving the practicality of indoor fire hydrants, making this device structure suitable for market promotion and use.

[0004] The above device is similar in function to the existing rotary fire hydrant, possessing a rotation function. However, in actual use, fire hydrants often need to perform firefighting tasks at locations at different heights or directions. This necessitates pulling the fire hose in different directions. Pulling the fire hose in different directions causes a tendency for bending to occur within the connection range between the fire hose and the fire hydrant. The bending at the connection point obstructs the water flow in the pipe, thereby increasing the water pressure at the hose connection. If the hose connection is not tight enough, it is highly likely that the hose will detach. Therefore, a fire hydrant rotary interface is proposed here to solve the above problems.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be described in further detail below.

[0032] This utility model discloses a fire hydrant rotating interface. (Refer to...) Figures 1-5 The fire hydrant includes a fire hydrant body 1, which includes a base 11 and a hydrant body 12. The hydrant body 12 is rotatably connected to the top of the base 11 and is provided with an interface mechanism 2.

[0033] The interface mechanism 2 includes a main tube 21. One end of the main tube 21 is connected to a connector 22 via a sealed bearing. A bellows 23 is fixedly connected to the connector 22. One end of the bellows 23 is fixedly connected to an interface tube 24. An annular seat 25 is provided on the outside of the main tube 21. An annular plate 26 is rotatably connected to one side of the annular seat 25. Two rectangular frames 27 are fixedly connected to one side of the annular plate 26. An extension plate 28 is slidably connected inside the rectangular frame 27.

[0034] A connecting rod 29 is rotatably connected to the extension plate 28. One end of the connecting rod 29 is fixedly connected to the outside of the interface pipe 24. A protective component 3 is provided on one side of the interface pipe 24. During use, the interface pipe 24 can swing around the connecting rod 29 as the axis. At the same time, since the connector 22 can rotate on one side of the main pipe 21, it can cooperate with the rotation of the interface pipe 24 to realize the function of flexibly swinging the interface pipe 24 in different directions. Thus, when this device is used, no matter how the fire extinguishing direction changes, it can be directly matched and adjusted through the interface pipe 24. This ensures that when the water hose is connected to the interface pipe 24, the water hose connection can remain straight, thereby reducing the pressure at the water hose connection during fire extinguishing, preventing the water hose from falling off, and improving the safety and stability during use.

[0035] An auxiliary block 291 is fixedly connected to the extension plate 28. A limiting groove is formed on one side wall of the rectangular frame 27. The auxiliary block 291 passes through the limiting groove and matches the limiting groove. A limiting plate 292 is fixedly connected to one side wall of the rectangular frame 27. A locking block 293 is slidably connected inside the auxiliary block 291. The locking block 293 can move flexibly inside the auxiliary block 291 and extends out of the auxiliary block 291. A locking slot 294 is formed on the limiting plate 292. The locking block 293 matches the locking slot 294. When the locking block... After 293 passes through the slot 294, the extension plate 28 can no longer move. A spring 295 is fixedly connected inside the auxiliary block 291. The spring 295 is fixedly connected to the card block 293. The spring 295 exerts an elastic force on the card block 293. A connecting plate 296 is fixedly connected to the inner side of the annular seat 25. The connecting plate 296 is distributed in an evenly spaced ring around the inner side of the annular seat 25. The connecting plate 296 is fixedly connected to the outer side of the main body tube 21. The annular seat 25 is fixedly connected to the outer side of the main body tube 21 through the connecting plate 296.

[0036] The protective component 3 includes a protective cover 31, an interface tube 24 extending into the interior of the protective cover 31 and matching the protective cover 31, and a ring plate 32 fixedly connected to the outside of the interface tube 24. The ring plate 32 has an arc-shaped groove 33 and a rectangular groove 34, which are evenly distributed around the ring plate 32. Adjacent arc-shaped grooves 33 and rectangular grooves 34 are connected. An L-shaped rod 35 is fixedly connected to the outside of the protective cover 31. The L-shaped rod 35 passes through the arc-shaped groove 33. A contact plate 36 is fixedly connected to one end of the L-shaped rod 35. After the L-shaped rod 35 passes through the arc-shaped groove 33, the contact plate 36 abuts against the other side of the ring plate 32 to ensure the stability of the protective cover 31 after installation.

[0037] The ring plate 32 has a positioning groove 37. The control frame 38 is fixedly connected to the outside of the protective cover 31. The positioning plate 39 is slidably connected inside the control frame 38. The positioning plate 39 extends out of the control frame 38 and passes through the positioning groove 37 and matches the positioning groove 37. The threaded rod 391 is rotatably connected inside the control frame 38 and extends out of the control frame 38. The threaded rod 391 passes through one side wall of the positioning plate 39 and is threadedly connected to the positioning plate 39. The protective cover 31 provides protection for one side of the interface tube 24.

[0038] In actual operation, when this device is used, the hydrant body 12 can rotate on the top of the base 11. This is the existing rotating fire hydrant structure, so it will not be described further. When fire fighting is required, the connection between the hose and the interface pipe 24 is not shown in the diagram to guide water to the fire fighting area. In specific operation, the connector 22 can rotate flexibly on one side of the main pipe 21, the corrugated pipe 23 can be flexibly extended and retracted, and the interface pipe 24 can be flexibly oscillating around the connecting rod 29. Based on the coordination of the above operation steps, when fire fighting is performed, the interface pipe 24 can be oscillated in different directions, causing the interface pipe 24 to face the fire fighting direction. At this time, the connection between the interface pipe 24 and the hose can also be straightened. Compared with the traditional connection method, where pulling the hose in different directions will cause the connection between the hose and the interface pipe 24 to bend, which will increase the water pressure and pose a risk of the connection falling off, it is safer and more reliable to use.

[0039] When not in use, in order to reduce the volume occupied, the interface tube 24 can be pushed towards the bolt body 12. The interface tube 24 drives the connecting rod 29 to move, and the connecting rod 29 drives the extension plate 28 to move into the rectangular frame 27, forming a shrinking effect. When the locking block 293 moves to the position of the locking slot 294, the spring 295 pushes the locking block 293 into the locking slot 294, thereby forming a locking state for the extension plate 28. Based on the above operation, it can be seen that the bellows 23 can shrink at this time, and the distance between the interface tube 24 and the bolt body 12 is reduced accordingly, which can effectively reduce the volume occupied and make it more flexible.

[0040] Finally, to prevent damage to the interface tube 24 due to collisions or corrosion during idle periods, thus affecting its service life, a protective cover 31 can be placed over one side of the interface tube 24 for protection. Specifically, the contact plate 36 is aligned with the rectangular groove 34 and inserted. When the protective cover 31 is tightly closed on the outside of the interface tube 24, the contact plate 36 passes through the rectangular groove 34. At this point, rotating the protective cover 31 causes the rectangular groove 34 to move towards the arc-shaped groove 33. Since the arc-shaped groove 33 is smaller than the contact plate 36, when the contact plate 36 moves behind the arc-shaped groove 33, it locks the protective cover 31 in place. Finally, to improve the stability of the protective cover 31 and prevent it from falling off, the threaded rod 391 is rotated. The threaded rod 391 moves the positioning plate 39 to the positioning groove 37, preventing the protective cover 31 from rotating. This further improves the stability of the protective cover 31 and effectively protects the interface tube 24.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
