Description

Technical Field

[0001] The utility model relates to the technical field of navigation lamp testing, in particular to a pressure testing tool for an embedded navigation lamp. Background Art

[0002] Navigational lighting usually refers to lighting equipment used in the aviation field to identify and guide the flight path, runways and airports of aircraft. These lights provide pilots with important navigation and positioning information at night or in bad weather conditions to ensure flight safety. Navigational lighting usually includes different types such as runway lights, direction indicators, altitude marker lights, and weather vane lights. Their colors, brightness and flashing modes have specific meanings and uses. Most of the existing pressure testing tools are large in size and not easy to carry and move. In the absence of factory testing equipment and means, such as before on-site installation, after inspection and maintenance, etc., when re-inspection is required, it is impossible to fully perform pressure sealing tests on the maintained products in accordance with standard requirements. Therefore, we have launched a pressure testing tool for embedded navigational lighting. Utility Model Content

[0003] The main purpose of the utility model is to provide a pressure testing tool for an embedded navigation light, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A pressure testing tool for embedded navigation lighting, including a conversion head, a safety valve installed on the left end of the conversion head, an adapter installed on the lower end of the conversion head, a three-way pipe fixedly connected to the lower end of the adapter, a sleeve locking hose plug fixedly connected to the left end of the three-way pipe, a test valve body fixedly connected to the right end of the three-way pipe, and a supporting device inserted and fixedly connected to the outer surface of the three-way pipe.

[0006] Preferably, the supporting device includes a supporting frame, which is an I-shaped structure, with two circular plates fixedly connected to the front and rear ends of the supporting frame, two reinforcement rods fixedly connected inside the supporting frame, connecting rings fixedly connected to the left and right upper ends of the supporting frame, and supporting legs fixedly connected to the front and rear outer surfaces of the two connecting rings.

[0007] Preferably, the two connecting rings are respectively inserted and fixedly connected with the left part and the right part of the outer surface of the three-way pipe.

[0008] Preferably, the right end of the test valve body is connected to a quick-connect plug, and the outer surface of the quick-connect plug is provided with a No. 2 sealing ring and a No. 1 sealing ring fixedly connected to the right part of the outer surface of the test valve body from left to right in sequence.

[0009] Preferably, the inner diameters of the two connecting rings are compatible with the diameter of the tee pipe.

[0010] Preferably, the four supporting legs are all arranged at an incline.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Connect the sleeve locking hose plug to the external standard water pipe, then connect the test valve body to the lamp, inject the external liquid into the sleeve locking hose plug, and then inject the liquid into the lamp through the tee pipe and the test valve body, so as to perform a water injection pressure test on the navigation lamp. Given the pressure required by the standard, the navigation lamp is completely placed in water and tested by observing the bubbles, which improves the convenience of post-maintenance inspection;

[0013] 2. By setting up a supporting device, the two connecting rings and the three-way pipe are inserted and fixed together, so that the supporting frame supports the two connecting rings and the three-way pipe, so that the entire tool can be supported after being placed in the water, avoiding the tool from tilting in the water to affect the test, thereby improving convenience.
