After the fire-fighting equipment has been used for a period of time, it is necessary to regularly detect the stiffness of the indoor fire hydrant box body to ensure the safety of use of the indoor fire hydrant box body.
[0003] In the existing stiffness detection work of the indoor fire hydrant box body, there are the following problems: First, when detecting the stiffness of the side plate and partition of the indoor fire hydrant box body, it is necessary to install a connecting seat through bolts and then apply pressure to the connecting seat through a lever. In this way, it is necessary to drill holes in the side plate and partition of the box body, resulting in damage to the box body shell and affecting the overall strength of the subsequent use of the indoor fire hydrant box body; Second, in the existing detection process, only the side plate and partition of the indoor fire hydrant box body are detected for stiffness, and the detection is not comprehensive enough. It cannot cover the brackets of the fire-fighting equipment, making it difficult to ensure the stiffness safety of the brackets after long-term use and there are potential safety hazards.

[0019] In order to make the technical means, creative features, achieved purposes, and functions of the utility model easy to understand, the present utility model will be further described below with reference to specific drawings.
[0020] In order to solve the problem that when detecting the existing stiffness, it is necessary to install a connecting seat through bolts and then apply pressure to the connecting seat through a lever, which requires drilling holes in the side plate and partition of the box, resulting in damage to the box shell and affecting the overall strength of the subsequent use of the indoor fire hydrant box. As shown in Figure 1, the present application includes an indoor fire hydrant box 1, the indoor fire hydrant box 1 includes a partition 3 at the middle position and side plates 2 on both sides. Inside the indoor fire hydrant box 1, a fire water inlet pipe 4 is provided at the upper layer, a fire hose reel bracket 5 is provided above the fire water inlet pipe 4, a fire hose bracket 8 is provided on one side of the fire water inlet pipe 4, and a fire nozzle bracket 7 and a fire alarm button bracket 6 are respectively provided above the fire hose bracket 8;
[0021] As Figure 2 and Figure 4As shown, two parallel pressure clamping plates 17 are respectively installed on the partition plate 3 and the side plate 2. The outer side of the inner pressure clamping plate 17 is provided with a card slot 20 with a hollow middle area, and the outer end of the inner side is provided with a limiting ejector rod 23. A clamping seat 21 is embedded inside the card slot 20. The outer side of the clamping seat 21 is connected with an inclined lever 14 or an L-shaped lever 16. Through holes are respectively opened at the upper and lower sides of the outer ends of the two parallel pressure clamping plates 17, and bolts pass through the through holes to clamp the two parallel pressure clamping plates 17 on the partition plate 3 and the side plate 2. Anti-slip gaskets 22 are provided on the inner sides of the inner ends of the two parallel pressure clamping plates 17. The length of the limiting ejector rod 23 is the same as the width of the partition plate 3 and the side plate 2. Pulling rings 10 are sleeved on the outer rod bodies of the inclined lever 14 and the L-shaped lever 16;
[0022] Specifically, the detection device of the present application does not need to drill holes in the partition plate 3 and the side plate 2 to install the connecting seat. The pressure clamping plate 17 is directly clamped on the partition plate 3 and the side plate 2. The clamping seat 21 is embedded inside the card slot 20, and then the partition plate 3 and the side plate 2 of the indoor fire hydrant box body 1 are respectively stressed through the inclined lever 14 and the L-shaped lever 16. After the stress application is completed, the deformation amount of the stressed area is measured by a dial indicator to realize stiffness detection.
[0023] In order to solve the problem that in the existing detection process, only the stiffness of the side plate and the partition plate of the indoor fire hydrant box body is detected, the detection is not comprehensive enough, and the bracket of the fire fighting equipment cannot be involved, resulting in the difficulty in ensuring the stiffness safety of the bracket after long-term use and there being potential safety hazards, as Figure 2 shown, a straight lever 9 is inserted into the hollow areas inside the fire hose reel bracket 5 and the fire alarm button bracket 6. A pulling ring 10 is sleeved on the outer rod body of the straight lever 9. A sleeve 15 is sleeved on the support rod of the fire hose bracket 8, and a pulling ring 10 is sleeved on the outer cylinder body of the sleeve 15.

[0025] Specifically, weights 19 of different quantities and weights are used for counterweighting. The plumb line 11 is pulled downward. The linear lever 9 pulls down the fire hose reel bracket 5 and the fire alarm button bracket 6 respectively. The sleeve 15 pulls down the support rod of the fire hose bracket 8. The connecting rod 13 pulls down the concave clamping plate 12. The inclined lever 14 and the L-shaped lever 16 pull down the side plate 2 and the partition plate 3 respectively. After a certain period of time, the tester uses a dial indicator to detect the deformation at the pressure application position. Among them, the partition plate 3 and the side plate 2 of the indoor fire hydrant box body 1 should have a maximum depression deformation of no more than 2 mm under the action of a torque of 150 N*m for 5 minutes, and the bracket should have a maximum depression deformation of no more than 2 mm under the action of a torque of 40 N*m for 2 minutes.
