[0019] Figure 2 It is a schematic diagram of the enlarged structure of point A in Example 1 of the present utility model. DETAILED DESCRIPTION

[0020] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0021] refer to Figure 1-2 , the embodiment of the utility model discloses: a fire hose pressure resistance detection device, including a frame 1, a fixing rod 2 is provided on the frame 1, a detection tube 3 is provided on the fixing rod 2, a fire hose 5 to be detected is provided in the detection tube 3, the hose joints 6 at both ends of the fire hose 5 pass through the detection tube 3, and fixing devices for fixing the hose joints 6 are respectively provided at both ends of the detection tube 3, the frame 1 is provided with connecting pipes at both ends of the detection tube 3, a fire connector 7 that is rotatably provided on the connecting pipe and engages with the hose joint 6, and a pressurized water pump 8 for injecting water into the fire hose 5 is provided on the frame 1.

[0022] Specifically, the fixing device includes a fixed block 12 and a rotating ring 15. The water hose joint 6 is symmetrically provided with a fixed channel. The detection tube 3 is provided with a sliding channel 13 connected to the fixed channel. The fixed block 12 is slidably arranged in the sliding channel 13. The detection tube 3 is provided with a spring 14 that pushes the fixed block 12 to slide into the fixed channel. One end of the spring 14 is connected to the fixed block 12, and the other end of the spring 14 is connected to the inner wall of the sliding channel 13. The rotating ring 15 is rotatably sleeved on the detection tube 3. A magnetic block (not shown in the figure) is provided in the rotating ring 15. The magnetic block is located on the horizontal line of the sliding channel 13, and the fixed block 12 has magnetic properties that are attracted to the magnetic block.

[0023] In order to further test the heat resistance of the fire hose 5, a heating groove is provided on the inner wall of the detection tube 3, a heating tube 9 is provided in the heating groove, a heat conducting layer 10 is provided on the heating tube 9, and an insulating layer 11 is provided on the inner wall of the heating groove to prevent heat from dissipating outward.

[0024] Preferably, the heat-conducting layer 10 is a heat-conducting silicone layer.

[0025] Preferably, the heat insulation layer 11 is a glass fiber heat insulation layer 11.

[0026] In order to connect the hose connector 6 with the fire connector 7, the connecting pipe is a hose. The connecting pipe is a hose, which makes it convenient for the staff to hold the fire connector 7 and connect it to the connecting connector.

[0027] In order to further facilitate the installation of the fire hose 5, a socket channel is provided on the frame 1, and the fixing rod 2 is inserted into the socket channel.

[0028] In order to facilitate the drainage of water after the fire hose 5 bursts, a drain pipe 4 is provided on the detection pipe 3, and a drain valve is provided on the drain pipe 4. The drain pipe 4 is connected to the external pipeline, and the water after the fire hose bursts enters the detection pipe 3 and is discharged through the drain pipe 4, thereby facilitating further operations of the staff.

[0029] Working principle:

[0030] During use, the fire hose 5 is inserted into the detection tube 3 and the hose connector 6 of the fire hose 5 is inserted into the end of the detection tube 3. The rotating ring 15 is then rotated, causing the magnetic block and the fixed block 12 to shift out of alignment. At this point, the spring 14 releases its elastic force, pushing the fixed block 12 to slide, causing it to slide into the fixed channel and engage with the hose connector 6, thereby securing the hose connector 6. The fire connector 7 is then connected to the hose connector 6. The pressurized water pump 8 then flows water into the fire hose 5 and continuously applies pressure to the acceptable value of the fire hose 5. The operator then observes the fire hose 5 to see if it has cracked, thereby determining whether the fire hose 5 is qualified. To remove the fire hose 5, the fire connector 7 and hose connector 6 are disconnected. The rotating ring 15 is then rotated so that the magnetic block on the rotating ring 15 is aligned with the fixed block 12. The magnetic block and the fixed block 12 attract each other, causing the fixed block 12 to slide into the sliding channel 13. The fire hose can then be removed, greatly facilitating the operation of the operator.
