Detailed Embodiments

[0018] The following further details the present application with reference to the drawings.

[0019] To more clearly understand the technical solutions shown in the embodiments of the present application, first, the working principle of the existing airtightness detection structure of the fire hose is introduced.

[0020] In the existing airtightness detection process of fire hoses, the form of inflating and immersing in water is mainly used for detection. Because this method has low cost and good detection effect, however, the existing equipment has relatively cumbersome operation processes such as immersion. It requires manual installation and then manual removal of the hose, resulting in low detection efficiency. Moreover, the operation of personnel needs to touch the liquid. In some cases, different additives are added to the water to observe clearly and magnify the presence of air bubbles to improve the sufficiency of detection. However, long-term contact with these liquids by personnel poses certain safety risks, which can cause skin damage. In addition, the operation of rolling up the hose after detection is not convenient enough. Therefore, it is necessary to improve the existing detection device to solve these existing problems.

The upper ends of the electric push rods 17 are fixedly connected to the lower surface of the movable plate 3. The connecting rods 18 are equidistantly and fixedly connected to the bottom surfaces near both sides inside the detection box 1. Through holes are formed in the movable plate 3 corresponding to the upper ends of the connecting rods 18, and the connecting rods 18 are slidably connected to the through holes in the movable plate 3.

The provided sliding block 4 can make the sliding of the two more smooth, and at the same time can connect movable plates 3 of different sizes. The provided connector 5 adopts a universal water hose connection structure, which can quickly connect one end of various water hose bodies 25 under the existing standard. The other end can be sealed by the provided sealing head 6, so that the water hose body 25 can be connected to the movable plate 3 and move along with it, and the air pressure inside it can be applied without leakage.
