Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixture testing equipment, specifically to a testing auxiliary device for testing the waterproof performance of lighting fixtures. Background Technology

[0002] In the production and quality control of lighting fixtures, waterproof performance is a core indicator for evaluating their reliability and service life. Currently, the industry commonly uses the spray test method as the main means of testing the waterproof performance of lighting fixtures. This method simulates a rainy environment by continuously spraying the surface of the lighting fixture with a high-pressure nozzle, and observes whether water enters the interior according to a preset time or standard to determine the waterproof effect. For details, please refer to the Chinese utility model patent with announcement number CN220794530U, entitled "A Waterproof Testing Device for Lighting Fixtures".

[0003] However, this method has significant technical drawbacks: Firstly, the accuracy of spray testing is limited by the spray angle, water pressure uniformity, and the subjectivity of manual observation. For example, spray dead zones or local water pressure fluctuations may result in some areas not being fully covered, and manual visual inspection is difficult to accurately identify trace amounts of water seepage, easily leading to misjudgments or missed detections. Secondly, traditional spray equipment typically uses an open circulation system, with a large amount of water being directly discharged after a single test, resulting not only in water waste but also increased environmental treatment costs for enterprises. Furthermore, spray testing cannot simulate the actual working conditions of lighting fixtures in complex environments (such as long-term immersion and condensate penetration), and cannot fully reflect the long-term stability of their sealing performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a testing auxiliary device for testing the waterproof performance of lamps.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An auxiliary testing device for testing the waterproof performance of lighting fixtures includes a water tank, a lifting device installed in the water tank, and a testing basket installed in the lifting device. The water tank contains a testing liquid. The lighting fixture is placed in the testing basket, and the lifting device moves the testing basket up and down to keep the lighting fixture at different depths in the water tank for immersion testing. The lifting device includes a main frame, a drive assembly, and a lifting component. The height of the main frame is higher than the height of the water tank. The drive assembly is installed on the top of the main frame. The lifting component is movably installed inside the main frame and connected to the drive assembly. The testing basket is installed on the lifting component.

[0007] In this utility model, the driving assembly includes a drive motor, transmission rods, and commutators. The drive motor is mounted on a crossbar at the top of the main frame and is a dual-head motor. The commutators are located on the crossbars on both sides of the main frame. The commutators on both sides are connected to the drive motor through the transmission rods. The commutators are connected to the lifting assembly. When the drive motor is working, it drives the transmission rods on both sides to rotate, and the transmission rods on both sides drive the lifting assembly to move through the commutators.

[0008] Furthermore, the lifting assembly includes lifting rods vertically arranged on both sides of the main frame, lifting plates mounted on the lifting rods on both sides, and guide rails vertically arranged on the main frame. The lifting rods are lead screws, and the top of the lifting rods is connected to the commutator, while the bottom is rotatably fitted on a rotating seat. The rotating seat is set on a crossbar at the bottom of the main frame, and the middle part of the lifting plate is fitted with the lifting rod, while the two ends are slidably fitted on the guide rails.

[0009] Furthermore, the lifting plate is provided with a lifting seat, which is threadedly engaged with a lead screw. The lifting seat is fixed below the lifting plate to support it. Both ends of the lifting plate are also provided with guide wheels that cooperate with the guide rail, and the guide wheels abut against both sides of the guide rail.

[0010] Furthermore, two lifting rods are respectively provided on both sides of the main frame. Correspondingly, in the drive assembly, the two sides of the drive motor are connected by multiple transmission rods and multiple commutators to form a T-shaped transmission mechanism. The transmission mechanism is connected to the drive motor through the transmission rods, and the two ends of the transmission mechanism are respectively connected to the two lifting rods through commutators. Two rotating seats are correspondingly provided on the crossbar at the bottom of the main frame, and two lifting seats are correspondingly provided on the lifting plates on both sides.

[0011] In this utility model, the main body of the testing basket is composed of multiple U-shaped support plates, two side plates, and four edge strips. The multiple support plates are arranged vertically and evenly. The two side plates are respectively set at the front and rear ends of the support plate arrangement direction. The four edge strips are respectively snapped into two pairs on both sides of the support plate arrangement direction. The upper part of the testing basket is covered by a metal fence, and one side of the metal fence is hinged to the main body of the testing basket.

[0012] Furthermore, a latch is provided on one side of the opening on the metal fence. The top of the latch is hinged to the metal fence, and the bottom of the latch is provided with a limiting block protruding to both sides. A limiting seat is provided on the outer side of the side plate below the latch, and the limiting seat is provided with a U-shaped limiting opening. Under normal conditions, the latch hangs down naturally so that its lower part enters the limiting opening, while the limiting block at the tail end abuts against the bottom of the limiting seat to form a lock.

[0013] This utility model has the following advantages and beneficial effects:

[0014] The lamps in the testing basket are precisely placed at different depths in the water tank using a lifting device, enabling comprehensive testing without blind spots. By controlling the immersion depth and time, the changes in the sealing performance of the lamps in a humid environment can be accurately reproduced, providing a reliable basis for assessing their long-term waterproof stability. The testing process does not require manual visual judgment of water leakage, eliminating subjective interference and making the waterproof performance assessment results more objective and accurate.

[0015] In addition, the device adopts a closed water storage tank design, and the tested liquid can be recycled, which significantly reduces the water cost and environmental treatment pressure of enterprises, and is in line with the development trend of green manufacturing.

However, this utility model is not limited to the following embodiments.

[0026] like Figures 1 to 6 As shown, this embodiment discloses a testing auxiliary device for testing the waterproof performance of lamps, including a water tank 1, a lifting device 2 installed in the water tank 1, and a testing basket 3 installed in the lifting device 2. The water tank 1 stores testing liquid. The lamp is placed in the testing basket 3, and the lifting device 2 moves the testing basket 3 up and down to keep the lamp at different depths in the water tank 1 for a period of time for immersion testing. Different depths correspond to different pressures, thereby enabling the testing of different waterproof levels and improving practicality. It should be noted that multiple lamps can be placed in the testing basket 3 according to their size, thereby enabling batch testing and improving production efficiency. Specifically, the lifting device 2 includes a main frame 21, a drive component 22, and a lifting component 23. The main frame 21 is a frame structure welded from multiple steel members. The height of the main frame 21 is higher than the height of the water tank 1. The drive component 22 is installed on the top of the main frame 21. The lifting component 23 is movably installed inside the main frame 21 and connected to the drive component 22. The testing basket 3 is installed on the lifting component 23.

[0027] In this embodiment, the drive assembly 22 includes a drive motor 221, a transmission rod 222, and a commutator 223. The drive motor 221 is mounted on a crossbar at the top of the main frame 21. In addition, the drive motor 221 is a dual-head motor. The commutator 223 is set on the crossbars on both sides of the main frame 21. The commutators 223 on both sides are connected to the drive motor 221 through the transmission rod 222. The commutator 223 is connected to the lifting assembly 23. When the drive motor 221 works, it drives the transmission rods 222 on both sides to rotate. The transmission rods 222 on both sides then drive the lifting assembly 23 to move through the commutator 223.

[0028] Furthermore, the lifting assembly 23 includes lifting rods 231 vertically arranged on both sides of the main frame 21, lifting plates 232 mounted on the lifting rods 231 on both sides, and guide rails 233 vertically arranged on the main frame 21. The lifting rods 231 are lead screws, and the top of the lifting rods 231 is connected to the commutator 223, while the bottom is rotatably fitted on a rotating seat 234. The rotating seat 234 is set on a crossbar at the bottom of the main frame 21. The middle part of the lifting plate 232 is fitted with the lifting rod 231, and the two ends are slidably fitted on the guide rails 233. Specifically, the lifting plate 232 is provided with a lifting seat 235, and the lifting seat 235... 5. The lifting seat 235 is fixed below the lifting plate 232 and supports it. The two ends of the lifting plate 232 are respectively provided with guide wheels 236 that cooperate with the guide rail 233. The guide wheels 236 abut against the two sides of the guide rail 233. The top drive assembly 22 drives the lifting rod 231 to rotate through the commutator 223. When the lifting rod 231 rotates, it drives the lifting plate 232 to move up and down along the guide rail 233 through the lifting seat 235. The detection basket 3 installed on the lifting plate 232 thus achieves lifting and lowering. By setting the guide wheels to abut against the two sides of the guide rail 233, the resistance can be reduced and the smoothness of the lifting plate 232 during the lifting process can be improved.

[0029] Furthermore, to better improve the stability of the lifting assembly 23, two lifting rods 231 are respectively provided on both sides of the main frame 21. Correspondingly, in the drive assembly 22, the two sides of the drive motor 221 are connected by multiple transmission rods 222 and multiple commutators 223 to form a T-shaped transmission mechanism. The middle part of the transmission mechanism is connected to the drive motor 221 through the transmission rods 222, and the two ends of the transmission mechanism are respectively connected to the two lifting rods 231 through the commutators 223. In addition, two rotating seats 234 are correspondingly provided on the crossbar at the bottom of the main frame 21, and two lifting seats 235 are correspondingly provided on the lifting plates 232 on both sides.

[0030] In this embodiment, after the detection basket 3 rises from the liquid, to facilitate drainage, the main body of the detection basket 3 is composed of multiple U-shaped support plates 31, two side plates 32, and four edge strips 33. The multiple support plates 31 are arranged vertically and evenly. The two side plates 32 are respectively set at the front end and rear end of the arrangement of the multiple support plates 31. The four edge strips 33 are respectively snapped into two groups on both sides of the arrangement direction of the support plates 31 and the side plates 32, specifically snapped into the upper and lower parts of the side. The upper part of the detection basket 3 is covered by a metal fence 34, and one side of the metal fence 34 is hinged to the main body of the detection basket 3 for easy opening and closing.

[0031] Furthermore, since the lamp will be subject to buoyancy when the detection basket 3 is immersed in the liquid, this buoyancy will cause the metal fence 34 to open, causing the lamp to float to the surface and affecting the detection. Therefore, a latch 35 is provided on one side of the opening on the metal fence 34. The top of the latch 35 is hinged to the metal fence 34, and the bottom of the latch 35 is provided with a limiting block 351 protruding to both sides. On the outside of the side plate 32, below the latch, there is a limiting seat 36. The limiting seat 36 is provided with a U-shaped limiting opening 361. Under normal conditions, the latch 35 hangs down naturally so that its lower part enters the limiting opening 361, while the limiting block 351 at the tail end abuts against the bottom of the limiting seat 36 to form a lock, preventing the metal fence 34 from opening.

[0032] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
