The center of the rubber hose inner liner is provided with a vent hole identical to the second air inlet. The rubber hose inner liner is also fitted with a compression sleeve, which is located on the upper side of the rubber sleeve. The lower end face of the rubber sleeve abuts against the outer convex ring of the rubber hose inner liner. Both the first air inlet and the second air inlet are connected to an air pump.

[0005] Furthermore, a sealing ring fitted on the main body is provided between the main body and the sliding seat.

[0006] Furthermore, a sealing ring installed on the sliding seat is provided between the sliding seat and the inner liner of the hose.

[0007] Furthermore, a sealing ring installed on the main body is provided between the main body and the inner liner of the hose.

[0008] Furthermore, a recessed ring is provided on the inner wall of the tubing sleeve.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This application uses air pressure as a power source to push the sliding seat to squeeze the rubber sleeve, causing the rubber ring to deform; the rubber ring and the inner diameter of the rubber tube form a radial seal, and the outer rubber tube sleeve tightly hugs the outer diameter of the rubber tube to prevent slippage, achieving rapid assembly and good sealing performance.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] A rapid pressure testing fixture for a rubber hose includes a main body 1, a sliding seat 2 slidably mounted on the lower section of the main body 1, a hose sleeve 3 located at the lower end of the sliding seat, a hose inner liner 6 mounted on the lower part of the main body 1, and a rubber sleeve 5 fitted on the hose inner liner 6. The main body 1 has a first air inlet 11 and a second air inlet 12. The first air inlet 11 communicates with the area between the main body 1 and the sliding seat 2. The upper end of the hose inner liner 6 passes through the hose sleeve 3 and the sliding seat 2 in sequence and is threadedly connected to the middle of the main body 1. The hose inner liner 6 has a vent hole with the same as the second air inlet 12 through its center. The hose inner liner 6 is also fitted with a compression sleeve 4, which is located on the upper side of the rubber sleeve 5. The lower end face of the rubber sleeve 5 abuts against the outer convex ring of the hose inner liner 6. The first air inlet 11 and the second air inlet 12 are both connected to an air pump.

[0014] Preferably, a sealing ring is provided between the main body 1 and the sliding seat 2, and the sealing ring is sleeved on the main body 1.

[0015] Preferably, a sealing ring is provided between the sliding seat 2 and the inner liner column 6 of the rubber tube, which is installed on the sliding seat 2.

[0016] Preferably, a sealing ring installed on the body 1 is provided between the main body 1 and the inner liner column 6 of the hose.

[0017] Preferably, the inner wall of the tubing sleeve 3 is provided with a concave ring 31, which can increase the friction between the tubing and the tubing sleeve 3 and prevent the tubing 7 from coming off during pressure testing.

[0018] In use, the quick-testing fixture is snapped onto the opening of the hose 7. The opening of the hose 7 is held between the rubber sleeve 5 and the hose sleeve 3. When the start switch is turned on, high-pressure gas enters the device through the air inlet 1. Under the pressure, the sliding seat 2 is pushed downwards, pushing the hose sleeve 3 and the compression sleeve 4 downwards. The rubber sleeve 5 deforms outwards, thus forming a seal with the inner wall of the hose. Under the action of the rubber sleeve 5, a radial seal is formed between the hose and the hose sleeve 3, thus locking the hose. When the inflation switch is turned on, test gas enters the hose through the second air inlet 12 to pressurize it. After reaching the test pressure, observe whether there are bubbles emerging from the hose. If no bubbles emerge, the hose is qualified.

[0019] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
