[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustibles, isolate combustion-supporting materials, and eliminate fire sources. Fire hydrants are important equipment in urban fire-fighting systems. They are used to provide fire-fighting water to respond to emergencies such as fires. During the use of fire hydrants, the connecting pipes of fire hydrants need to be connected to fire hoses or other equipment to ensure the normal supply of fire-fighting water.

[0003] However, existing fire hydrant connection devices may have some difficulties in operation. For residents, especially in emergency situations, a simple-to-operate connection device is needed to quickly and accurately connect fire hydrants to equipment such as fire hoses.

[0004] Current fire hydrant connection equipment may have the following problems: the connection process is complicated and requires multiple steps, which may be confusing for inexperienced residents; the connection is not firm and is prone to leakage, resulting in waste of fire water and unstable connection; the sealing performance is poor and leakage is prone to occur at the connection, affecting the fire fighting effect.

[0005] To this end, we have proposed a fire hydrant connection device that is suitable for residents to operate easily. The device only requires people to insert the fixing rod into the first through hole for fixing, without too many steps, thus saving time and effort. At the same time, the connection gap can be sealed during connection, thereby further preventing water leakage. Utility Model Content

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-6 As shown, the technical solution adopted by the utility model is specifically as follows: a fire hydrant connection device suitable for residents to operate easily, comprising a fire hydrant body 1, on which a first connecting pipe 2 and a second connecting pipe 3 are arranged, and the first connecting pipe 2 is connected to the second connecting pipe 3 through a connecting assembly;

[0027] The connecting assembly includes a first fixed block 4 arranged on the first connecting tube 2 and a second fixed block 5 arranged on the second connecting tube 3. The first fixed block 4 is provided with a first through hole 6 and a slide groove 7. The second fixed block 5 is provided with a fixing rod 8 inserted into the first through hole 6. The fixing rod 8 is provided with a circular groove 9 and four second through holes 10. A telescopic assembly is arranged inside each of the second through holes 10. Four arc-shaped limit plates 11 are arranged inside the circular groove 9. The four arc-shaped limit plates 11 are connected to form a circular limit ring matching the circular groove 9, and the bottom of each arc-shaped limit plate 11 is connected to the corresponding telescopic assembly. An extrusion assembly that moves inside the slide groove 7 is arranged between the first fixed block 4 and the second fixed block 5, and an arc-shaped sealing plate 12 for sealing the connection gap is arranged on the extrusion assembly.

[0028] Its working principle is as follows: when people need to use the fire hydrant to connect the second connecting pipe 3 with the first connecting pipe 2, people only need to hold the second connecting pipe 3 and dock it with the first connecting pipe 2. At this time, when the second connecting pipe 3 moves, the fixing rod 8 enters the first through hole 6. When entering, the four arc-shaped limit plates 11 are moved to the inside of the circular groove 9 through the telescopic component, so that the fixing rod 8 can enter the first through hole 6. Then, after entering, the four arc-shaped limit plates 11 are opened by the telescopic component to limit and fix. When the fixing rod 8 moves, the extrusion component moves inside the slide groove 7, so that the arc-shaped sealing plate 12 seals the gap between the first connecting pipe 2 and the second connecting pipe 3, thereby preventing water leakage. The device only requires people to insert the fixing rod 8 into the first through hole 6 for fixing, without too many steps, to achieve the effect of saving time and effort. At the same time, the connection gap can be sealed when connecting, thereby further preventing water leakage.

[0029] The diameter of the fixing rod 8 is the same as the diameter of the first through hole 6 , so that the fixing rod 8 can enter the first through hole 6 .

[0030] At the same time, the width of the four arc-shaped limit plates 11 is the same as the width of the circular groove 9. This arrangement enables the arc-shaped limit plates 11 to enter the circular groove 9 when the telescopic assembly is extended and retracted, so that the fixing rod 8 can move inside the first through hole 6.

[0031] What can be selected is: the shape of the arc-shaped limiting plate 11 can be a trapezoidal plate. The advantage of the trapezoidal plate is that it does not require manpower for extrusion, thereby achieving the effect of saving time and labor.

[0032] The telescopic assembly includes a first spring 13 arranged inside the second through hole 10 . The top of the first spring 13 is connected to the first piston disc 14 . The top of the first piston disc 14 is provided with a first connecting rod 15 . The top of the first connecting rod 15 is connected to the arc-shaped limit plate 11 .

[0033] When the arcuate limiting plate 11 is squeezed, the arcuate fiber plate drives the first connecting rod 15 to make the first piston disc 14 squeeze the first spring 13 , so that the arcuate fiber plate enters the circular groove 9 , so that the fixing rod 8 can enter the first through hole 6 .

[0034] The extrusion assembly includes a first wedge block 16 arranged at the bottom of the fixed rod 8 and a second fixed shaft 17 arranged inside the slide groove 7, a second slider 18 and a second spring 19 are sleeved on the second fixed shaft 17, second springs 19 are arranged on both sides of the second slider 18, and a second connecting rod 20 is installed on one side of the second slider 18, one end of the second connecting rod 20 away from the second slider 18 is connected to the arc-shaped sealing plate 12, and a second wedge block 21 that fits the inclined surface of the first wedge block 16 is arranged on the top of the second connecting rod 20.

[0035] When the fixing rod 8 moves into the first through hole 6, the first wedge block 16 moves on the second wedge block 21, so that the second wedge block 21 drives the second connecting rod 20 to move the second slider 18 on the second fixed shaft 17, and at the same time drives the arc-shaped sealing plate 12 to move downward, thereby sealing the connecting gap between the first connecting pipe 2 and the second connecting pipe 3, thereby preventing water leakage.

[0036] A sealing layer is provided at the bottom of the arc-shaped sealing plate 12, and the material of the sealing layer is rubber to improve the sealing effect.

[0037] At the same time, the second slider 18 matches the slide groove 7. Matching here means that the second slider 18 can move smoothly inside the slide groove 7 without getting stuck.

[0038] It should be noted that four arc-shaped sealing plates 12 are provided, and when connected, the four arc-shaped sealing plates 12 form a complete circular sealing ring, thereby sealing the connecting gap between the first connecting pipe 2 and the second connecting pipe 3 .

[0039] During disassembly, people only need to drive the telescopic assembly into the circular groove 9 by the four arc-shaped fiberboards, and then drive the fixing rod 8 to be pulled out from the first through hole 6 by the second connecting pipe 3 to complete the disassembly.

[0040] The working principle of the utility model is as follows: when people need to use the fire hydrant to connect the second connecting pipe 3 with the first connecting pipe 2, people only need to hold the second connecting pipe 3 and dock it with the first connecting pipe 2. At this time, when the second connecting pipe 3 moves, the fixing rod 8 enters the first through hole 6. When entering, the four arc-shaped limit plates 11 are moved to the inside of the circular groove 9 by the telescopic assembly, so that the fixing rod 8 can enter the first through hole 6. Then, after entering, the four arc-shaped limit plates 11 are opened by the telescopic assembly to limit and fix. When the fixing rod 8 moves, the extrusion assembly moves inside the slide groove 7, so that the arc-shaped sealing plate 12 seals the gap between the first connecting pipe 2 and the second connecting pipe 3, thereby preventing water leakage. The device only requires people to insert the fixing rod 8 into the first through hole 6 for fixing, without too many steps, to achieve the effect of saving time and effort. At the same time, the connection gap can be sealed when connecting, thereby further preventing water leakage.

[0041] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
