TECHNICAL FIELD
[0001] The present application relates to the technical field of detection equipment, and particularly relates to a fire hose end fixing device for fire hose detection. BACKGROUND
[0002] A fire hose is a flexible tube used to transport high-pressure water or foam. Traditional fire hoses have a rubber inner lining and are wrapped in a linen braid. Modern hoses are made from synthetic materials such as polyurethane. Both ends of the hose have metal couplings that allow the attachment of another hose to extend the length or a nozzle to increase the pressure of the liquid stream.
[0003] The fire hose needs to be detected after production, such as design working pressure, test pressure, minimum burst pressure, wet hose water leakage, unit length mass, elongation, expansion rate and torsion direction, etc. When detecting the water leakage, one end of the fire hose sample is connected to the water source, and the other end is sealed with a sealing device with an exhaust valve. After water injection, pressure preservation and water collection can be carried out to obtain the water leakage. When the fire hose end is connected to the water source, the interface of the end is connected to the water pipe. It is time-consuming and laborious to detect multiple fire hoses. The end cannot be quickly fixed and connected to the water source. The efficiency is low. Therefore, a fire hose end fixing device for fire hose detection is provided. SUMMARY

DETAILED DESCRIPTION
[0026] In order to better understand the purpose, structure and function of the application, the application of a fire hose end fixing device for fire hose detection will be further described in detail below in combination with the drawings.
[0027] As Figures 1 to 4 shown, a fire hose end fixing device for fire hose detection includes a support frame 1, a sealed water injection assembly 2 arranged in the middle of the support frame 1, and a plug-in fixing mechanism 3 arranged on the upper and lower sides of the support frame 1.
[0028] The support frame 1 includes a support base 11, a support ring 12 arranged on the top of the support base 11, and a fixed tube 13 arranged at the center position of the support ring 12; four threaded holes into which screws can be inserted are arranged on the support base 11, and the screws fix the support base 11 to the ground.
[0029] The sealed water injection assembly 2 includes a water injection pipe 21 inserted into the inside of the fixed tube 13, a sealing sleeve 22 made of rubber and in an arc shape is fixedly connected to the outside of the end of the water injection pipe 21 inserted into the water hose interface 4, a hemispherical stop block 23 is fixedly connected to the outside of the water injection pipe 21 and arranged close to the sealing sleeve 22, the planar side of the stop block 23 faces the sealing sleeve 22 and the arc-shaped side faces the fixed tube 13, when the water injection pipe 21 is inserted into the water hose interface 4, the sealing sleeve 22 deforms to fill and seal the gap between the water injection pipe 21 and the water hose interface 4, when the plug-in fixing mechanism 3 is pushed into the center, the stop block 23 pushes the plug-in fixing mechanism 3 to make it fold towards the center, so that the water hose interface 4 can be quickly clamped and fixed.
[0030] The water injection pipe 21 is fixedly connected with a water pipe interface at one end away from the sealing sleeve 22. The outer side of the water injection pipe 21 is fixedly connected with two limiting rings 24 located at the two ends of the fixed pipe 13 respectively. The limiting rings 24 limit the position of the water injection pipe 21. The two limiting rings 24 ensure that the water injection pipe 21 will not be separated from the fixed pipe 13. When the water hose interface 4 is sleeved on the outer side of the water injection pipe 21 and is pushed, the limiting rings 24 are blocked by the fixed pipe 13, so that the position of the water injection pipe 21 will not continue to slide, ensuring that the water hose interface 4 and the water injection pipe 21 can be filled and sealed by the sealing sleeve 22, and the plug-in fixing mechanism 3 just clamps the fixed ring 5.
[0031] The plug-in fixing mechanism 3 includes two extension rods 31 fixedly connected on one side of the support ring 12 and parallel to each other. The two extension rods 31 are fixedly connected with a rotating shaft 32 at one end away from the support ring 12. The outer side of the rotating shaft 32 is sleeved with a sleeve ring 33. The right side of the sleeve ring 33 is fixedly connected with a special-shaped rod 34. The left side of the sleeve ring 33 is fixedly connected with a L-shaped clamping rod 35. When the sealing water injection assembly 2 is connected to the water hose interface 4, the stop block 23 drives the special-shaped rod 34 to rotate around the rotating shaft 32, so that the clamping rod 35 rotates towards the fixed ring 5. The two clamping rods 35 limit the position of one side of the fixed ring 5, so that the water hose interface 4 is fixed in the center of the plug-in fixing assembly.
[0032] The plug-in fixing mechanism 3 further includes a limiting block 38 fixed between the opposite sides of the two extension rods 31 in a semi-cylindrical shape. The arc surface of the limiting block 38 faces the sealing water injection assembly 2. The end of the special-shaped rod 34 away from the rotating shaft 32 is fixedly connected with a limiting rod 36 in an arc shape and with a hook-shaped end. The limiting rod 36 faces the limiting block 38 and is fixedly connected with a pushing plate 37 extending towards the extension rod 31 at the hook-shaped end. The limiting rod 36 is made of elastic metal. When the water hose interface 4 is fixed, the limiting rod 36 is hooked at the limiting block 38 under the driving of the special-shaped rod 34, so as to keep the clamping rod 35 fixed with the water hose interface 4 and not to be easily released.
[0033] The plug-in fixing mechanism 3 further includes a rigid spring 39 fixed between the opposite sides of the two extension rods 31 and facing the sealing water injection assembly 2. The rigid spring 39 is used to reset the special-shaped rod 34.
[0034] In use, the support frame 1 is fixed on the ground where it is needed, and when the water leakage of the fire hose is detected, the water injection pipe 21 is connected to the water source at the end away from the sealing sleeve 22, the hose connector 4 is sleeved outside the sealing sleeve 22, and the hose connector 4 is pushed towards the support ring 12; the stop block 23 pushes the two special-shaped rods 34, the special-shaped rods 34 rotate around the pivot 32, the two clamping rods 35 rotate around the pivot 32 and fold towards the center to be sleeved outside the fixed ring 5, at the same time, the sealing sleeve 22 is extruded to be deformed, the space between the hose connector 4 and the water injection pipe 21 is filled and sealed, the hose connector 4 is fixed in the center of the plug-in fixing mechanism 3; the limiting rod 36 is hooked on the limiting block 38 while the special-shaped rod 34 rotates, so that the special-shaped rod 34 is prevented from rotating to cause the hose connector 4 to be separated, the water source is opened to inject water into the hose through the water injection pipe 21 and detect the water leakage, after the detection, the limiting rod 36 is moved by the push plate 37, so that the limiting rod 36 is separated from the limiting block 38, and the rigid spring 39 rebounds to drive the special-shaped rod 34 to rotate, so that the hose connector 4 is pushed out.
