[0029] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0030] The embodiments of this patent are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0031] In the description of this patent, it should be understood that the terms "middle", "bottom", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "both sides", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0032] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "assembly" should be interpreted broadly. For example, they can refer to a fixed connection or installation, a detachable connection or installation, or an integral connection or installation. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0033] Please refer to Figures 1 to 2 One embodiment discloses a clamping device for testing the performance of a gas hose, the structure of which includes a first track component 1, the first track component 1 having movable tracks arranged at least near two ends; a sliding component 2 movably connected to the movable tracks along a first direction, the end of the sliding component 2 having a connecting component; a second track component 3 having a second movable track arranged along a second direction, the first direction being perpendicular to the second movable track; and a clamping component 4 including a base plate and a clamp arranged on the base plate, the base plate being slidably connected to the second movable track.

[0034] Specifically, the first track component 1 is arranged with a movable trajectory, allowing it to move the sliding component 2 along a first direction. A connecting component is arranged at the end of the sliding component 2. The connecting component has various interface forms depending on the testing requirements, such as threaded interfaces or quick couplings, to facilitate connection to testing equipment or airtightness testing devices. This application does not specify a particular interface. The second track component is arranged perpendicular to the first track component, and a second movable trajectory is arranged on it along a second direction. By adjusting the position of the base plate on the second track component, simulation of different bending radii of the gas hose can be achieved. The clamping component includes a base plate and a connecting component arranged on the first track component. The clamps on the base plate can be designed in various forms, such as V-shaped clamps and U-shaped clamps, to hold the gas hose. During the test, the sliding component moves along the first direction (i.e., the direction of the movement trajectory). By adjusting the position of the sliding component 2 on the first track component, and cooperating with the second track component to bend the gas hose, the bending state of the gas hose in actual use is simulated, thereby more accurately evaluating its ozone aging resistance performance. After the gas hose is fixed in position, gas at a certain pressure is injected into the hose through an external airtightness testing device, and the gas pressure change is monitored in real time. If the gas pressure remains stable within a set time, it indicates that the hose has good airtightness; if the gas pressure drops beyond the set value, it indicates that the hose has a leakage problem.

[0035] Please refer to Figure 3 In one embodiment, the first track component 1 includes a first base 11, and the two ends of the first base 11 are detachably connected to a second base 12; wherein the moving track is arranged on the surface of the second base 12.

[0036] Specifically, the first track component 1 includes a first base 11 and a second base 12. The two are detachably connected, and the total length of the moving track can be adjusted by replacing the second base with a different length according to the actual testing needs, thereby realizing the testing of gas hoses of different lengths. In one embodiment, the two ends of the first base are provided with connection interfaces that match the second base. For example, the interface can adopt various methods such as threaded connection, snap connection or pin connection. When it is necessary to test gas hoses of different lengths, it is only necessary to loosen the connection structure between the first base and the second base, remove the original second base, replace it with a new second base of appropriate length, and re-tighten the connection structure.

[0037] In one embodiment, the moving track is arranged as a groove on the surface of the second base 12. The sliding member 2 includes a first slider embedded in the moving track. The surface of the first slider has a threaded hole, and a bolt is threadedly connected at the location of the threaded hole. In the above embodiment, the bolt fixes the position of the first slider by cooperating with the threaded hole. Specifically, when it is necessary to fix the position of the sliding member 2, the bolt is aligned with the threaded hole, and the bolt is rotated to gradually screw it into the threaded hole until one end of it presses against the groove, thus limiting the position of the first slider.

[0038] In one embodiment, the surface of the second base 12 is provided with graduations corresponding to the moving trajectory; and / or, the surface of the second track component 3 is provided with graduations corresponding to the second moving trajectory; when the sliding component moves on the moving trajectory, the operator can intuitively read its current position value by observing the relative position of the edge of the sliding component and the graduation lines, thereby achieving precise control of the position of the sliding component.

[0039] In one embodiment, the connecting member is arranged as a threaded pipe joint.

[0040] Please refer to Figure 4 In one embodiment, the first track component 1 includes a first body 14 and a second body 17, which are connected by a threaded assembly.

[0041] Please continue to refer to this. Figure 4 Furthermore, the first body 14 is provided with a cavity, and the threaded assembly includes a threaded sleeve 15, which is embedded in one end of the first body 14 and is in communication with the cavity; the threaded rod 16 is threadedly connected to the threaded sleeve 15, and one end of the threaded rod 16 is rotatably connected to the second body 17. The rotation of the second body 17 allows for controllable spacing between the first body 14 and the second body 17, thereby adapting to hoses of different lengths.

[0042] Please refer to Figure 5 In one embodiment, in order to better limit the gas hose, at least one support member 5 is arranged on the side wall of the second track member 3. The support member 5 includes a support part connected to the second track member 3 at one end and a limiting member connected to the other end of the support part. The limiting member limits the gas hose to be tested. The support part is a metal hose. While maintaining a certain structural strength, the metal hose can bend freely according to the action of external force and maintain a new shape after bending, so that the hose can bend according to the expected shape to meet different usage scenarios and requirements. The bending shape of the gas hose to be tested can be adjusted.

[0043] In summary, this utility model discloses a clamping device for testing the performance of a gas hose. Its structure includes a first track component, a sliding component, a second track component, and a clamping component. The first track component has a movable track, along which the sliding component can move in a first direction. Its end is equipped with a connecting component for connecting to testing equipment or an airtightness testing device. The second track component is perpendicular to the first track component and has a second movable track arranged in a second direction. The base plate of the clamping component can slide on this track to simulate different bending radii of the gas hose. The clamp is designed according to the hose specifications, such as V-shaped or U-shaped, for clamping the hose. During testing, the sliding component moves on the first track, cooperating with the second track to bend the hose, simulating actual use conditions to evaluate its ozone aging resistance. After fixing the hose, it is inflated using an external airtightness testing device, and the pressure change is monitored to determine the hose's airtightness.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
