Description

Technical Field

[0001] This utility model relates to the field of high-intensity lamp head manufacturing technology, specifically to a testing device for high-intensity lamp heads. Background Technology

[0002] Internal airtightness testing of high-intensity lamp holders is a crucial testing item, as airtightness directly affects the lamp holder's performance in extreme environments. For example, in environments with rain, humidity, or high dust levels, even if the lamp holder's outer casing meets waterproof and dustproof standards, a failure to achieve adequate internal airtightness will still allow moisture and dust to enter the lamp holder, damaging the internal circuitry or shortening the lamp's lifespan. Current methods for testing the airtightness of high-intensity lamp holders involve immersing the lamp holder in water and observing whether bubbles emerge from it. If there are leakage channels inside the lamp holder, air will escape through these channels and form bubbles on the water surface.

[0003] When the above-mentioned technology uses water immersion tests to test the airtightness of high-intensity lamp heads, if the leakage inside the lamp head is very small or occurs in some hard-to-reach locations, the leakage may not be detected. The main reason is that if the leakage channel or aperture is very small, the gas flow rate is slow, and not enough obvious bubbles will form on the water surface, or even no bubbles will be generated, resulting in poor detection accuracy. Therefore, a detection device for high-intensity lamp heads is needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a detection device for high-intensity lamp heads, solving the technical problem mentioned in the background art where the gas flow speed is slow due to the small internal leakage channel or aperture of the lamp head, making it impossible to form obvious bubbles, thus resulting in low accuracy of leakage detection.

[0005] The technical solution of this utility model is as follows: a detection device for a high-intensity lamp head, including a detection box and a drain pipe fixedly connected to the detection box. The top of the detection box is provided with a mounting plate, and the inner wall of the mounting plate is fixed with a lamp tube. Two lifting components are symmetrically arranged on the left and right sides of the detection box, and a detection component is provided on the rear side of the detection box away from the drain pipe.

[0006] The detection assembly includes a pressure guiding cylinder fixed to the rear side of the detection box. A piston is slidably sleeved inside the pressure guiding cylinder. A power assembly for driving the piston to move laterally and reciprocally is provided on the side of the detection box. A one-way suction pipe, a one-way discharge pipe, and a one-way monitoring pipe are fixedly connected to the pressure guiding cylinder. One end of the one-way monitoring pipe is fixedly connected to a pressure gauge.

[0007] Preferably, the power assembly includes a cylinder fixed to the rear side of the detection box, a slide plate fixed to the telescopic end of the cylinder, a pull rod fixed to the side of the slide plate, and one end of the pull rod penetrating the inner wall of the pressure guide cylinder and fixed to the piston.

[0008] Preferably, a limiting ring is fixed to the inner wall of the pressure guiding cylinder. The limiting ring has the same outer diameter as the piston and is in contact with the piston.

[0009] Preferably, a one-way valve is installed inside the one-way suction pipe, the one-way discharge pipe, and the one-way monitoring pipe.

[0010] Preferably, the lifting assembly includes a mounting recess fixed to one side of the detection box, an electric slide rail fixed inside the mounting recess, a support rod slidably connected to the outer wall of the electric slide rail, and one end of the support rod being fixed to the mounting plate.

[0011] Preferably, a telescopic tube is provided between the lamp tube and the one-way drain pipe, and the two ends of the telescopic tube are fixedly connected to the opposite ends of the lamp tube and the one-way drain pipe, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a cylinder to drive a piston in a lateral reciprocating motion within a pressure-conducting cylinder. Combined with the coordinated operation of a one-way suction pipe, a one-way discharge pipe, and a one-way monitoring pipe, this detection method accurately monitors pressure changes within the high-intensity lamp head, promptly identifying leaks. If no bubbles form and the pressure rises steadily, it indicates a good seal in the lamp head; conversely, if the pressure does not rise significantly or bubbles appear, it suggests a leak. This significantly improves the accuracy and efficiency of high-intensity lamp head detection, effectively reducing the risk of missed detections and ensuring the reliability of the high-intensity lamp head's quality.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] In existing technologies, when using water immersion tests to check the airtightness of high-intensity lamp heads, leaks inside the lamp head that are very minor or occur in hard-to-reach locations may go undetected. This is primarily because if the leak channel or aperture is very small, the gas flow rate is slow, and insufficiently noticeable bubbles may not form on the water surface, or even any bubbles may be generated at all, leading to poor detection accuracy. Please refer to [link / reference]. Figures 1-4 This embodiment provides a detection device for a high-intensity lamp head, including a detection box 1 and a drain pipe 11 fixedly connected to the detection box 1. A mounting plate 2 is provided on the top of the detection box 1, and an ambulance tube 3 is fixed to the inner wall of the mounting plate 2. Two lifting components 4 are symmetrically arranged on the left and right sides of the detection box 1. Each lifting component 4 includes a mounting recess 41 fixed to one side of the detection box 1, and an electric slide rail 42 is fixed inside the mounting recess 41. A mounting rod 43 is slidably connected to the outer wall of the electric slide rail 42, and one end of the mounting rod 43 is fixed to the mounting plate 2. A telescopic tube 6 is provided between the ambulance tube 3 and the one-way drain pipe 54, and both ends of the telescopic tube 6 are fixedly connected to the opposite ends of the ambulance tube 3 and the one-way drain pipe 54, respectively. The high-intensity lamp head is connected to the ambulance tube 3 by being mounted on its end face. The activation of the electric slide rail 42 causes the mounting rod 43 on its outer wall to slide down. This downward movement provides the force to push the mounting plate 2 downwards. As the mounting plate 2 slides down with the mounting rod 43, the entire structure causes the ambulance tube 3 to move downwards. At this moment, the downward movement of the lamp tube 3 compresses the telescopic tube 6 and pushes the lamp head into the water in the detection box 1.

[0022] like Figure 2 and Figure 4As shown, when using a water immersion test to check the airtightness of a high-intensity lamp head, if the leakage inside the lamp head is very small or occurs in some hard-to-reach locations, the leakage may go undetected. This is mainly because if the leakage channel or aperture is very small, the gas flow rate is slow, and insufficiently noticeable bubbles will form on the water surface, or even no bubbles will be generated, leading to poor detection accuracy. To improve the accuracy of high-intensity lamp head airtightness testing, the following settings are implemented: A detection component 5 is installed on the rear side of the detection chamber 1, away from the drain pipe 11. The detection component 5 includes a pressure guide cylinder 51 fixed to the rear side of the detection chamber 1. A piston 52 is slidably fitted inside the pressure guide cylinder 51, and a limit ring is fixed to the inner wall of the pressure guide cylinder 51. 57. The limiting ring 57 has the same outer diameter as the piston 52 and is in contact with the piston 52. The limiting ring 57 is used to prevent the piston 52 from moving past the one-way suction pipe 53. A power assembly for driving the piston 52 to move laterally and reciprocally is provided on the side of the detection box 1. The power assembly includes a cylinder 58 fixed to the rear side of the detection box 1. A slide plate 59 is fixed to the telescopic end of the cylinder 58. A pull rod 510 is fixed to the side of the slide plate 59. One end of the pull rod 510 passes through the inner wall of the pressure guide cylinder 51 and is fixed to the piston 52. A one-way suction pipe 53, a one-way discharge pipe 54, and a one-way monitoring pipe 55 are fixedly connected to the pressure guide cylinder 51. One-way valves are installed inside the one-way suction pipe 53, the one-way discharge pipe 54, and the one-way monitoring pipe 55. One end of the one-way monitoring tube 55 is fixedly connected to a pressure gauge 56. To more accurately detect minute leaks, a high-sensitivity digital pressure sensor is selected. This sensor is accurate to very small pressure changes (e.g., 0.01 Pa). The digital pressure gauge has higher resolution and can react more quickly to minute pressure fluctuations, especially when detecting minute leaks. The cylinder 58 is activated, causing its extension end to drive the slide plate 59 to reciprocate laterally, which in turn drives the lever 510 to move the piston 52 laterally within the pressure-conducting cylinder 51. When the piston 52 moves to the left, the one-way suction tube 53 opens, and outside gas is drawn into the pressure-conducting cylinder 51, while the one-way discharge tube 54 and the one-way monitoring tube 55 close. Conversely, when the piston 52 moves to the right, the one-way suction tube 53 closes, and the one-way discharge tube 54 and the one-way monitoring tube 55 open. One end of the one-way monitoring tube 55 is connected to the pressure gauge 56 to monitor changes in air pressure. Gas flows into the lamp head through the one-way drain tube 54. The pressure gauge 56 will display the changes in air pressure during the rise. If no bubbles are formed and the air pressure continues to rise and remains stable, it indicates that the seal is good. If the air pressure does not rise significantly or bubbles appear, it indicates that there is a leakage problem in the lamp head. This can significantly improve the accuracy, comprehensiveness and efficiency of high-intensity lamp head detection and reduce the risk of missed detection.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
