Utility Model Content

[0006] In order to solve the technical problem that when testing an LED lamp, the light emitted by the LED lamp cannot be isolated, thereby affecting the color consistency test result, the utility model provides an LED lamp aging test device.

[0007] The utility model adopts the following technical scheme to achieve: an LED lamp aging test device.

[0008] It comprises a shell and a sliding mechanism, wherein a plurality of placement plates are arranged at equal distances inside the shell through the sliding mechanism, and the inner cavity of the shell is divided into a plurality of test compartments through the placement plates;

[0010] Through the above technical solution, by arranging a plurality of placement plates inside the housing to divide the inside of the housing into a plurality of test compartments, the utilization rate of the housing space can be increased, so that the aging test can be performed more efficiently.

[0011] The sliding mechanism enables the mounting plate to be moved out of the housing more conveniently, and then the LED lamp tube can be placed on the mounting plate for clamping and installation more conveniently.

[0012] The sealing mechanism can make the placement plate move out of the housing smoothly on the one hand, and ensure the sealing of the test compartment on the other hand, thereby making the aging test result more accurate.

[0013] As a further improvement of the above solution, the sliding mechanism includes a slide plate and a slide rail, the two slide plates are fixed on the placement plate, and the two slide rails are symmetrically opened on the shell, and the slide rails slide in the slide plate.

[0014] According to the above technical solution, the placing plate is pulled to drive the slide plate to slide in the slide rail, so that the placing plate can be conveniently moved out of the housing to a great extent, making it more convenient to limit the position of the LED lamp.

[0015] As a further improvement of the above solution, the sealing unit includes an elastic unit, an engagement unit and an extrusion unit;

[0016] The elastic unit includes a pressure block slot, a slide bar slot, a slide bar, a sliding sleeve block and a spring 2. The pressure block slot is arranged on the shell on one side of the pressure block extension slot and is connected with the channel 1 to form a channel 2 for the pressure block and the rack plate to move. The two slide bar slots are symmetrically arranged in the pressure block slot, and the ends of the two slide bars are fixed in the slide bar slots. The sliding sleeve block slides on the slide bar, one end of the spring 2 is welded on the sliding sleeve block, and the other end of the spring 2 is welded in the slide bar slot, the middle part of the spring 2 is wound on the slide bar, and the adjacent ends of the two sliding sleeve blocks are fixed on the pressure block.

[0017] Through the above technical solution, under the elastic action of the second spring, when the pressing block is not subjected to the pressure of the placement plate, the pressing block can return to the inner cavity of the housing through the second channel and the first channel, thereby preparing for the next light shielding effect. In addition, when the pressing block moves, the sliding sleeve slides on the sliding rod, further increasing the stability of the movement of the pressing block.

[0018] As a further improvement of the above scheme, the meshing unit includes a rack plate, a gear, a rotating rod, a rope groove and a winding unit, the rack plate is fixed to one end of the pressure block located in the pressure block slot, the two rope grooves are both opened on the outer shell in the pressure block slot, and are connected to channel two to form channel three for the gear to rotate, the two ends of the two rotating rods are both arranged in the rope groove through bearings, and the gear is fixed on the rotating rod, and the two gears form a meshing connection structure with the rack plate.

When the ball is pulled to track section one by spring four, it cannot give pressure to the rubber plate, and then the two springs three contract. When the ball is pulled to track section two by the rope, it gives pressure to the two rubber plates, and then the two springs three stretch to promote the contact and extrusion of the two rubber plates and the slide plate.

[0022] Through the above technical solution, when the rope is pulled, the rotating rod can pull the ball closer to the rope groove when winding the rope. Then the ball moves from the first section of the track to the second section of the track, and then the two springs three are stretched, so that the two rubber plates contact and squeeze the two ends of the slide, thereby ensuring the sealing of the slide inside the slide. And under the action of the pulley, the smoothness of the rope during movement can be increased, and the friction between the rope groove and the rope groove can be reduced. Under the action of spring four, when the rotating rod releases the rope, the ball can return from the second section of the track to the first section of the track.

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0036] Embodiment 1:

[0037] Please combine Figure 1-6 , an LED lamp aging test device of this embodiment includes a housing 1 and a sliding mechanism, wherein a plurality of placement plates 2 are arranged at equal distances inside the housing 1 through the sliding mechanism, and the placement plates 2 divide the inner cavity of the housing 1 into a plurality of test compartments;

[0038] The sealing mechanism includes a limit groove 9, a rubber pad 10, a pressure block extension groove 11, a pressure block 17 and a sealing unit. Multiple limit grooves 9 are opened in the shell 1, and one end of the rubber pad 10 is fixed in the limit groove 9. The end of the rubber pad 10 away from the limit groove 9 is provided with a groove for inserting the placement plate 2. Two pressure block extension grooves 11 are symmetrically opened on the rubber pad 10 and are connected with the groove and the inner cavity of the shell 1 to form a channel for the pressure block 17 to move. The pressure block 17 can drive the sealing unit to complete the light-shielding property of the test compartment.

[0039] The sliding mechanism includes a slide plate 7 and a slide rail 8 . The two slide plates 7 are fixed on the placement plate 2 , and the two slide rails 8 are symmetrically opened on the housing 1 . The slide rails 8 slide in the slide plates 7 .

[0040] The implementation principle of the LED lamp aging test device of the present application is as follows: when performing an aging test on an LED lamp, first take out the placement plate 2 from the housing 1, so that the slide plate 7 slides on the slide rail 8 (while moving the placement plate 2, the placement plate 2 does not separate from the housing 1). Place the LED lamp tube between the two clamping plates 6, use the elasticity of two springs 5 ​​to clamp the LED lamp tube, and plug the power interface at one end of the LED lamp tube into the power board 3 for power supply, and the preparation work is completed.

[0041] When the placement plate 2 is pushed back into the housing 1, the slide plate 7 slides on the slide rail 8, and one end of the slide plate 7 is in contact with the rubber plate 28. As the placement plate 2 is pushed, one end of the placement plate 2 is contacted with the pressing block 17, and as the placement plate 2 is pushed, the pressing block 17 is pressed from the rubber pad 10 into the pressing block extension groove 11 and moves into the pressing block entry groove 12, so that the other end of the placement plate 2 is clamped in the rubber pad 10. During the process of the placement plate 2 being clamped in the rubber pad 10, the pressing block 17 is continuously pushed from the rubber pad 10 into the pressing block extension groove 11 and moves into the pressing block entry groove 12, stretching the spring 2 16, and the sliding sleeve 15 slides on the slide bar 14, driving the rack plate 18 to move in the pressing block entry groove 12, and driving the gear 19 and the rotating rod 20 to rotate under the meshing connection between the rack plate 18 and the gear 19. The rope 21 is wound around the rotating rod 20, and the rope 21 slides on the pulley 22, pulling the rolling ball 25 to move from the track 1d to the track 2e, and the spring 4 29 is stretched, so that the two fixing plates 27 can be compressed, so that the two rubber plates 28 are close to each other. The opposite ends of the two rubber plates 28 are attached to the slide plate 7 and slightly squeezed, and then the door on one side of the shell 1 can be closed and locked with the shell 1, and one end of the door contacts the placement plate 2, so that the placement plate 2 can be stably placed in the shell 1. Through the sealing of the rear side of the placement plate 2 by the rubber pad 10, the sealing of the two rubber plates 28 on the two sides of the placement plate 2, and the sealing of the door on the other side of the placement plate 2, it can be ensured that the inner cavity of the shell 1 on the entire placement plate 2 is completely in a sealed and isolated state, and light cannot be stolen, thereby ensuring the accuracy of the test.

[0042] During the inspection, a series of inspection equipment such as a humidity sensor and a color temperature sensor are arranged in the inner cavity of the housing 1 above the mounting plate 2 to inspect the LED lamp tube, and the inspection is performed for a certain period of time according to the needs of the site.

[0043] When the detection is completed, the door on one side of the shell 1 is opened, and the rebound potential energy of the spring 2 16 drives the pressure block 17 back to its original position, pushing the placement plate 2 out of the inside of the shell 1 a certain distance, and the rebound potential energy of the spring 4 29 causes the rolling ball 25 to return from the track 2 e to the track 1 d.
