Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to an adjustable fire hydrant connected to a water-adding pipeline. Background Art

[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility, which can be roughly divided into two categories: ground fire hydrants and underground fire hydrants.

[0003] An underground fire hydrant is an outdoor underground fire water supply facility. It is used to supply water to fire trucks or directly connect to water hoses and water guns for fire fighting. It is a special facility for outdoor fire water supply. It is installed underground and does not affect the city appearance and traffic. It consists of valve body, elbow, valve seat, valve disc, drain valve, valve stem and interface. Underground fire hydrants are essential fire extinguishing water supply devices in cities, factories, mines, power stations, warehouses, docks, residences and public places.

[0004] In the prior art, underground fire hydrants are usually connected to water supply pipes, which mainly include a vertical pipe and a curved pipe. The lower end of the vertical pipe is connected to the underground fire hydrant, and the curved pipe is connected to the upper end of the straight pipe. The fire hose can be connected to the curved pipe to add water to the fire truck through the fire hose.

[0005] However, since the elbow is generally fixed at the upper end of the vertical pipe, the angle of the elbow is fixed. When the fire truck is not parked in the direction of the elbow, the fire hose is prone to bending during pressurized water delivery. The bend will reduce the water delivery speed of the fire hose, thereby reducing the water delivery efficiency.

[0006] Therefore, how to design an adjustable fire hydrant connection water pipe has become a problem we currently need to solve. Utility Model Content

[0007] 1. Technical issues to be solved

[0008] In view of the deficiencies of the prior art, the utility model provides an adjustable fire hydrant connected to a water supply pipe to solve the problems mentioned in the above background technology.

[0009] (II) Technical solution

[0010] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable fire hydrant connection water supply pipeline, comprising a vertical pipe, a curved pipe and a rotating connection assembly, wherein the curved pipe is connected to the upper end of the vertical pipe through the rotating connection assembly, and the rotating connection assembly comprises a first connecting seat and a second connecting seat, wherein the first connecting seat is fixedly mounted on the upper end of the vertical pipe, and the second connecting seat is fixedly mounted on the lower end of the curved pipe, a connecting pipe is arranged at the center of the first connecting seat, and the upper end of the connecting pipe is plugged into the second connecting seat, a connecting slip ring is arranged at the bottom of the second connecting seat, and an annular groove matching the connecting slip ring is provided at the top of the first connecting seat, and the connecting slip ring is slidably connected in the annular groove;

[0011] The top surface of the first connecting seat is provided with a plurality of annularly distributed positioning grooves, and positioning components are symmetrically arranged on both sides of the second connecting seat.

[0012] Preferably, a sealing ring is abutted between the upper end of the connecting pipe and the second connecting seat.

[0013] Preferably, a sealing ring is slidably connected between the outer circumference of the connecting pipe and the inner wall of the second connecting seat.

[0014] Preferably, the positioning assembly includes a spring embedded in the second connecting seat and a positioning block abutting against the lower end of the spring.

[0015] Preferably, a shift block is fixedly connected to one side of the positioning block, and the shift block slides through the outer wall of the second connecting seat.

[0016] Preferably, a plurality of reinforcing ribs are evenly distributed on the outer circumference of the first connecting seat and the second connecting seat.

[0017] (III) Beneficial effects

[0018] The utility model provides an adjustable fire hydrant connection water supply pipe, which has the following beneficial effects:

[0019] First, the vertical pipe and the bent pipe are connected by setting a rotating connection assembly. Since the connecting slip ring of the first connecting seat can slide in the annular groove of the second connecting seat, the first connecting seat and the second connecting seat can rotate relative to each other, so that the bent pipe can rotate independently, which is convenient for adjusting the angle of the bent pipe.

[0020] Secondly, by setting the positioning groove and the positioning assembly, when the angle of the elbow needs to be adjusted, the dial block can be pushed upward to move the positioning block out of the positioning groove, and the elbow can be rotated and adjusted. When the elbow drives the second connecting seat to rotate to a certain angle, the spring will push the positioning block to insert into different positioning grooves to fix the angle of the elbow and ensure the stability of the elbow during use. The elbow can be rotated to the direction of the fire truck according to the position where the fire truck is parked, effectively avoiding the fire hose from bending during pressurized water delivery and affecting the water adding efficiency.

[0029] like Figure 1-4 As shown, the utility model provides a technical solution: an adjustable fire hydrant connection water supply pipe, including a vertical pipe 1, a curved pipe 2 and a rotating connection assembly 3, the lower end of the vertical pipe 1 is fixedly connected to the fire hydrant, the curved pipe 2 is connected to the upper end of the vertical pipe 1 through the rotating connection assembly 3, the rotating connection assembly 3 includes a first connecting seat 31 and a second connecting seat 32, and a plurality of reinforcing ribs 310 are evenly distributed on the outer circumference of the first connecting seat 31 and the second connecting seat 32, and the structural strength of the first connecting seat 31 and the second connecting seat 32 can be enhanced by the reinforcing ribs 310.

[0030] Reference Figure 1 and Figure 3 The first connecting seat 31 is fixedly mounted on the upper end of the vertical pipe 1, and the second connecting seat 32 is fixedly mounted on the lower end of the curved pipe 2. A connecting pipe 33 is provided in the center of the first connecting seat 31. The upper end of the connecting pipe 33 is inserted into the second connecting seat 32. A connecting slip ring 34 is provided at the bottom of the second connecting seat 32. An annular groove 35 matching the connecting slip ring 34 is provided on the top of the first connecting seat 31. The connecting slip ring 34 is slidably connected in the annular groove 35. The vertical pipe 1 and the curved pipe 2 are connected by setting a rotating connection component 3. Since the connecting slip ring 34 of the first connecting seat 31 can slide in the annular groove 35 of the second connecting seat 32, the first connecting seat 31 and the second connecting seat 32 can rotate relative to each other, so that the curved pipe 2 can rotate independently, which is convenient for adjusting the angle of the curved pipe 2.

[0031] Reference Figure 3 and Figure 4The top surface of the first connecting seat 31 is provided with a plurality of annularly distributed positioning grooves 36, the number of the positioning grooves 36 is an even number, and at least 8, and positioning components 37 are symmetrically arranged on both sides of the second connecting seat 32, and the positioning component 37 includes a spring 371 embedded in the second connecting seat 32 and a positioning block 372 abutting against the lower end of the spring 371, and a shift block 373 is fixedly connected to one side of the positioning block 372, and the shift block 373 slides through the outer wall of the second connecting seat 32. By setting the positioning grooves 36 and the positioning components 37, when the angle of the elbow 2 needs to be adjusted, The dial block 373 can be pushed upward to move the positioning block 372 out of the positioning groove 36, so that the elbow 2 can be rotationally adjusted. When the elbow 2 drives the second connecting seat 32 to rotate to a certain angle, the spring 371 will push the positioning block 372 to insert into different positioning grooves 36, fix the angle of the elbow 2, and ensure the stability of the elbow 2 during use. Therefore, the elbow 2 can be rotated to the direction of the fire truck according to the position where the fire truck is parked, effectively avoiding the fire hose from bending easily during pressurized water delivery, and avoiding affecting the water adding efficiency.

[0032] Furthermore, a sealing ring 38 is abutted between the upper end of the connecting tube 33 and the second connecting seat 32, and a sealing ring 39 is slidably connected between the outer circumference of the connecting tube 33 and the inner wall of the second connecting seat 32. By setting the sealing ring 38 and the sealing ring 39, a sealing effect can be achieved between the connecting tube 33 and the second connecting seat 32.

[0033] The working process of the utility model is as follows: the vertical pipe 1 and the curved pipe 2 are connected by setting a rotating connection component 3. Since the connecting slip ring 34 of the first connecting seat 31 can slide in the annular groove 35 of the second connecting seat 32, the first connecting seat 31 and the second connecting seat 32 can rotate relative to each other, so that the curved pipe 2 can rotate independently, which is convenient for adjusting the angle of the curved pipe 2. When the angle of the curved pipe 2 needs to be adjusted, the dial block 373 can be pushed upward to move the positioning block 372 out of the positioning groove 36, and the curved pipe 2 can be rotated and adjusted. When the curved pipe 2 drives the second connecting seat 32 to rotate to a certain angle, the spring 371 will push the positioning block 372 to insert into different positioning grooves 36, fix the angle of the curved pipe 2, and ensure the stability of the curved pipe 2 during use. Therefore, the curved pipe 2 can be rotated to the direction toward the fire truck according to the parking position of the fire truck, effectively avoiding the fire hose from bending easily during pressurized water delivery, and avoiding the water adding efficiency from being affected.
