[0021] 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.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a rubber hose pressure testing device, including a pressure testing device disposed inside the working chamber 1 of the testing equipment. The pressure testing device consists of a support 2, a connector A3, a clamp 4, a connector B5, and a valve assembly 6. The clamp 4 is disposed on the support 2. The connector A3 is disposed on one side of the clamp 4 and fixed to the support 2. The connector B5 is disposed on the other side of the clamp 4 and fixed to the support 2. The valve assembly 6 is disposed on the side of the connector B5. The clamp 4 consists of an upper clamp 41, a lower clamp 42, symmetrically arranged movable components 43, and symmetrically arranged adjusting components 44. The upper clamp 41 is disposed on top of the lower clamp 42. The movable component 43 is located at the connection point of the upper clamp 41 and the lower clamp 42 on one side, and the symmetrically arranged adjustment component 44 is located at the connection point of the upper clamp 41 and the lower clamp 42 on the other side. Through the designed adjustable clamp 4, the versatility of the equipment is improved: it can adapt to rubber hoses of different diameters, eliminating the need for separate clamps for each specification, covering more testing scenarios, and one device can complete various tests, reducing equipment procurement and maintenance costs; it also reduces costs and improves efficiency: it reduces the frequency of clamp replacement, saves preparation time before testing, simplifies inventory management, eliminates the need to store a large number of fixed clamps, saves space and costs, and makes the testing process smoother and more efficient;Ensuring testing quality: Precisely adaptable to hoses, ensuring secure fixation and preventing leaks or displacement due to poor fit. This improves the accuracy of pressure data, reduces safety hazards, and enhances the reliability of test results. The symmetrically arranged movable component 43 consists of a through hole 431, a fixing post 432, a fixing groove 433, and a movable rod 434. The through hole 431 is located on one side surface of the upper clamp 41, the fixing groove 433 is located on one side surface of the lower clamp 42, and the fixing post 432 penetrates the inside of the through hole 431, with its bottom end secured. The movable rod 434 passes through the inner side of the bottom end of the fixed column 432 and is inserted into the inner side of the fixed groove 433. The two ends of the movable rod 434 are fixed to the inner walls of the fixed groove 433 respectively. The adjusting assembly 44 consists of a threaded groove 441, a threaded column 442, and a rotating handle 443. The threaded groove 441 is opened on the other side surface of the upper clamp 41, and the threaded column 442 passes through the inner side of the threaded groove 441. The surface of the threaded column 442 is threadedly connected to the inner side of the threaded groove 441, and the bottom end of the threaded column 442 is connected to the other side surface of the lower clamp 42. With the surface fixed, the rotating handle 443 is fixed to the top of the threaded post 442. When the rubber hose is installed inside the clamp 4, the rotating handle 443 is rotated synchronously, and the threaded connection between the threaded post 442 and the threaded groove 441 drives the upper clamp 41 to move upward as a whole. After the threaded post 442 separates from the threaded groove 441, the upper clamp 41 is rotated around the through movable rod 434 as the center, so that the upper clamp 41 is in an unfolded state. Then the rubber hose is placed on the lower clamp 42, and then the upper clamp 41 is flipped over. The original position is restored by rotating the handle 443 in the opposite direction, causing the upper clamp 41 to move downwards as a whole. When the dimensions of the upper clamp 41 and the lower clamp 42 are in contact with the rubber hose, the position of the rubber hose is fixed in the clamp 4. Multiple observation ports are provided on the surface of the upper clamp 41. The valve assembly 6 consists of a valve body 61 and a connection port 62. The connection port 62 is located on the bracket 2 and communicates with the inner side of the connector B5. The valve body 61 is mounted on the bracket 2, and the bracket 2 is bolted to the working chamber 1 of the testing equipment.

[0023] In this embodiment, preferably, a perforated plate is provided at the bottom inner side of the working chamber 1 of the testing equipment. When performing pressure testing on the rubber hose, it is necessary to inject and discharge pressure medium. The perforated plate's hole design facilitates the flow of medium in the working chamber, avoiding medium accumulation or poor flow. After the test, it can also help the residual medium to be quickly discharged from the working chamber, improving testing efficiency and reducing the potential impact of residual medium on the equipment.

[0024] The working principle and usage process of this utility model are as follows: When testing the rubber hose using a pressure testing device, first check whether each component of the pressure testing device is normal, then check the appearance of the rubber hose to be tested to confirm that there are no obvious defects such as damage or cracks. After the preparation work is completed, place the rubber hose in the clamp 4, and connect one end to the connector A3 and the other end to the connector B5 to ensure a firm connection. Then, inject the selected pressure medium into the rubber hose through the connection port 62 of the valve assembly 6, open the valve body 61, and use an external pressure testing pump to pump the medium in. Close the valve body 61 to prevent medium leakage. Through the external pressure control system, gradually increase the pressure value according to the set pressure rise rate to slowly increase the internal pressure of the hose. At the same time, observe the condition of the hose to check for leaks, deformation, etc. The pressure value inside the hose is monitored in real time through an external pressure sensor. After the test is completed, open the valve body 61 of the valve assembly 6 to discharge the medium in the hose and depressurize. After the pressure drops to zero, disassemble the rubber hose, clean the equipment, and record the test results.
