Technical Field
[0001] This utility model relates to the field of fire protection technology, and in particular to a fire-fighting connection device for household faucets. Background Technology
[0002] A household faucet fire-fighting connection device is a connection device used in the fire-fighting water supply system of a household or building. Its main function is to ensure that the water source of the household or building can be quickly connected to the fire-fighting system in the event of a fire so that fire-fighting water can be used to extinguish the fire.
[0003] When using household faucets, some faucets are made by heat-fusion of PVC pipes, and then the valve on the outlet pipe is opened to supply water. When the connecting pipe is connected to the faucet's outlet pipe, it is easy for it to shake under high pressure, which can cause the connection between the connecting pipe and the outlet pipe to loosen and fall off, thus affecting the effectiveness of the fire-fighting connection device. Utility Model Content
[0004] The technical problem this utility model aims to solve is that when the connecting pipe is connected to the water outlet pipe of the faucet, it is easy for the pipe to shake under high pressure, which can cause the connection between the connecting pipe and the water outlet pipe to loosen and fall off, thus affecting the effectiveness of the fire-fighting connection device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a household faucet fire-fighting connection device, including a water outlet pipe, a valve provided on one side of the water outlet pipe, a connecting pipe provided on one side of the water outlet pipe, and a reinforcement device on one side of the connecting pipe. The reinforcement device reinforces the connection between the connecting pipe and the water outlet pipe by means of a reinforcement plate.
[0006] The effect achieved by the above components is as follows: When using a household faucet, some household faucets will have threads on the water outlet pipe. When fire water supply is needed, it will be threaded to the connecting pipe of the fire connection device. A reinforcement device will be used to reinforce the connection between the connecting pipe and the water outlet pipe. Then, the valve on the water outlet pipe will be opened to supply water.
[0007] Preferably, the reinforcement device includes a square tube, a first bolt, a bracket, a second bolt, and a reinforcement plate. The square tube is disposed on one side of the connecting pipe. The first bolt is inserted into one side of the square tube to fix it to the bracket inside the square tube. The second bolt rotates on one side of the bracket to drive the surface reinforcement plate to move.
[0008] The effect achieved by the above components is as follows: After the connecting pipe and the outlet pipe are threaded together, the square tube is positioned on the side of the connecting pipe closer to the valve. Then, the bracket is moved so that one side of the bracket is inserted into the square tube fixed to the connecting pipe. Then, the first bolt is rotated so that it passes through the square tube and is threadedly fixed to the bracket. Then, the second bolt is rotated so that it rotates on one side of the bracket. Then, the reinforcing plate threaded on the surface of the second bolt is brought close to the outlet pipe. Then, the reinforcing plate abuts against and is fixed to the outlet pipe. This completes the reinforcement of the connection between the connecting pipe and the outlet pipe. By using the reinforcement device, the connection between the connecting pipe and the outlet pipe can be reinforced, preventing the connecting pipe from shaking during high-pressure water discharge, which could lead to loosening and detachment at the connection between the connecting pipe and the outlet pipe, thereby improving the effectiveness of the fire-fighting connection device.
[0009] Preferably, an operating block is provided on one side of the second bolt, and the operating block lifts one side of the second bolt.
[0010] The effect achieved by the above components is that by fixing the operating block to the second bolt, the size of one side of the second bolt is increased, making it easier for the second bolt to be rotated.
[0011] Preferably, a bearing is provided on the side of the second bolt near the bracket, and the bearing reduces the friction between the second bolt and the bracket.
[0012] The effect achieved by the above components is that by fixing the bearing to the bracket and the second bolt, the friction between the two is reduced, and the second bolt can be rotated more easily on one side of the bracket.
[0013] Preferably, a reinforcing plate is provided on one side of the reinforcing plate, and the reinforcing plate increases the strength of the reinforcing plate.
[0014] The effect achieved by the above components is to increase the strength of one side of the reinforcing plate by fixing the reinforcing plate to one side, thereby preventing the reinforcing plate from deforming under stress.
[0015] Preferably, one side of the bracket is provided with several anti-slip blocks to increase the friction on one side of the bracket.
[0016] The effect achieved by the above components is to increase the friction on one side of the bracket by fixing several anti-slip blocks on one side, thereby making the bracket easier to grip and move.
[0017] Preferably, the bracket has a trapezoidal block on the side near the square tube, and the trapezoidal block measures one side of the bracket's dimensions.
[0018] The effect achieved by the above components is as follows: by fixing the bracket to the side of the square tube with the trapezoidal block, the size of one side of the bracket is reduced, and then the bracket is more easily inserted into the square tube.
[0019] Preferably, a washer is provided on the side of the first bolt near the square tube to increase the contact area between the first bolt and the square tube.
[0020] The effect achieved by the above components is that the gasket at the gap between the first bolt and the square tube abuts and fixes them together, thereby increasing the contact area at the connection between the two, so that the first bolt can better fix the bracket.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a reinforcement device, the connection between the connecting pipe and the outlet pipe can be reinforced to prevent the connecting pipe from shaking when high-pressure water is discharged, which could lead to loosening and detachment at the connection between the connecting pipe and the outlet pipe, thereby improving the effectiveness of the fire protection connection device.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Example 1, Figures 1 to 4 The illustrated fire-fighting connection device for a household faucet includes a water outlet pipe 1, a valve 2 on one side of the water outlet pipe 1, a connecting pipe 3 on one side of the water outlet pipe 1, and a reinforcing device 4 on one side of the connecting pipe 3. The reinforcing device 4, through a reinforcing plate 45, reinforces the connection between the connecting pipe 3 and the water outlet pipe 1. When using a household faucet, some faucets have threads on the water outlet pipe 1. When fire-fighting water supply is needed, this threaded connection is made to the connecting pipe 3 of the fire-fighting connection device. The reinforcing device 4 reinforces the connection between the connecting pipe 3 and the water outlet pipe 1, and then the valve 2 on the water outlet pipe 1 is opened to supply water.
[0032] Figures 1 to 4 The reinforcement device 4 shown includes a square tube 41, a first bolt 42, a bracket 43, a second bolt 44, and a reinforcement plate 45. The square tube 41 is disposed on one side of the connecting pipe 3. The first bolt 42 is inserted into one side of the square tube 41 to fix it to the bracket 43 inside the square tube 41. The second bolt 44 rotates on one side of the bracket 43 to drive the surface reinforcement plate 45 to move. After the connecting pipe 3 and the outlet pipe 1 are threaded together, the square tube 41 is positioned on the side of the connecting pipe 3 closest to the valve 2. Then, the bracket 43 is moved so that one side of the bracket 43 is inserted into the square tube 41 fixed to the connecting pipe 3. Then, the first bolt 42 is rotated so that the first bolt 42 passes through the square tube 41 and is threadedly fixed to the bracket 43. Then, the second bolt 44 is rotated so that the second bolt 44 rotates on one side of the bracket 43. Then, the reinforcing plate 45 threaded on the surface of the second bolt 44 is brought close to the outlet pipe 1. Then, the reinforcing plate 45 abuts against and is fixed to the outlet pipe 1. Then, the reinforcement of the connection between the connecting pipe 3 and the outlet pipe 1 is completed. By using the reinforcement device 4, the connection between the connecting pipe 3 and the outlet pipe 1 can be reinforced, preventing the connecting pipe 3 from shaking when high-pressure water is discharged, which could lead to loosening and detachment at the connection between the connecting pipe 3 and the outlet pipe 1, thereby improving the effectiveness of the fire-fighting connection device.
[0033] Figures 1 to 4An operating block 46 is provided on one side of the second bolt 44, which raises one side of the second bolt 44. By fixing the operating block 46 to the second bolt 44, the raised side of the second bolt 44 is made easier to rotate. A bearing 47 is provided on the side of the second bolt 44 near the bracket 43, which reduces the friction between the second bolt 44 and the bracket 43. By fixing the bearing 47 to the bracket 43 and the second bolt 44, the reduced friction makes it easier for the second bolt 44 to rotate on one side of the bracket 43.
[0034] Figures 1 to 4 The reinforcing plate 45 shown has a reinforcing plate 48 on one side, which increases the strength of the reinforcing plate 45. By fixing the reinforcing plate 48 to one side of the reinforcing plate 45, the strength of that side is increased, preventing deformation under stress. The bracket 43 has several anti-slip blocks 49 on one side to increase friction. By fixing several anti-slip blocks 49 to one side of the bracket 43, the friction of that side is increased, making the bracket 43 easier to grip and move.
[0035] Figures 1 to 4 The bracket 43 shown has a trapezoidal block 410 on the side near the square tube 41, which reduces the size of one side of the bracket 43. The trapezoidal block 410 is used to fix the bracket 43 to the side near the square tube 41, thus lowering the size of one side of the bracket 43 and making it easier to insert the bracket 43 into the square tube 41. A washer 411 is provided on the side of the first bolt 42 near the square tube 41 to increase the contact area between the first bolt 42 and the square tube 41. The washer 411 at the gap between the first bolt 42 and the square tube 41 abuts against both, increasing the contact area at the connection point and thus allowing the first bolt 42 to better secure the bracket 43.
[0036] Working principle: When using a household faucet, some household faucets have threads on the outlet pipe 1. When fire water supply is needed, it will be threaded to the connecting pipe 3 of the fire connection device. The reinforcement device 4 is used to reinforce the connection between the connecting pipe 3 and the outlet pipe 1. Then, the valve 2 on the outlet pipe 1 is opened to supply water. After the connecting pipe 3 and the outlet pipe 1 are threaded together, the square tube 41 is positioned on the side of the connecting pipe 3 closest to the valve 2. Then, the bracket 43 is moved so that one side of the bracket 43 is inserted into the square tube 41 fixed to the connecting pipe 3. Then, the first bolt 42 is rotated so that the first bolt 42 passes through the square tube 41 and is threadedly fixed to the bracket 43. Then, the second bolt 44 is rotated so that the second bolt 44 rotates on one side of the bracket 43. Then, the reinforcing plate 45 threaded on the surface of the second bolt 44 is brought close to the outlet pipe 1. Then, the reinforcing plate 45 abuts against and is fixed to the outlet pipe 1. Then, the reinforcement of the connection between the connecting pipe 3 and the outlet pipe 1 is completed. By using the reinforcement device 4, the connection between the connecting pipe 3 and the outlet pipe 1 can be reinforced, preventing the connecting pipe 3 from shaking when high-pressure water is discharged, which could lead to loosening and detachment at the connection between the connecting pipe 3 and the outlet pipe 1, thereby improving the effectiveness of the fire-fighting connection device.
