Description

Technical Field

[0001] This utility model relates to the field of LED lighting testing technology, and in particular to an LED lighting pressure resistance testing device. Background Technology

[0002] LED lights are widely used in modern lighting. However, during their production, transportation, and use, they may be subjected to various external forces, which places demands on their compressive strength. Insufficient compressive strength can lead to damage, such as bulb breakage or internal circuit damage, affecting not only the normal use of the lights but also posing safety hazards.

[0003] Traditional testing methods often rely on manual operation and simple tools for compression testing. This method is not only inefficient, but also makes it difficult to guarantee the accuracy of the test results, which cannot meet the needs of large-scale production and quality control. Therefore, an LED lamp compression resistance testing device is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5 One embodiment of this utility model is a pressure resistance testing device for LED lamps, comprising:

[0034] Frame 1 is fixedly installed on the ground to support equipment parts;

[0035] The fixed structure 2 is set on the frame 1 and includes a worktable 21 fixed on the frame 1 and a slider 23 sliding on the worktable 21. A clamping plate 24 is fixedly installed on the slider 23. A rotating disk 27 is rotatably connected to the worktable 21. An arc-shaped guide groove 28 is opened on the rotating disk 27 to drive the slider 23 to move. A second clamping block 211 and a first clamping block 29 are provided on the clamping plate 24 for clamping and fixing the light bulb.

[0036] In this embodiment, a limiting post 26 is fixedly connected to the bottom of the clamping plate 24, and the limiting post 26 is slidably connected inside the arc-shaped guide groove 28.

[0037] The worktable 21 is fixedly connected to the guide rail 22, and the slider 23 is provided with a slide groove 25. The slider 23 is slidably connected to the guide rail 22 through the slide groove 25.

[0038] The second clamping block 211 is fixedly connected to the clamping plate 24, and the first clamping block 29 is connected to the clamping plate 24 by a spring. The second clamping block 211 is located above the first clamping block 29.

[0039] When the LED bulb is placed in the first clamp 29, the bottom of the bulb is clamped between the first clamp 29, and the middle part of the bulb is clamped between the second clamp 211.

[0040] A top plate 3 is fixedly connected to the bottom of the frame 1. A hydraulic cylinder 4 is fixedly installed on the top plate 3. A detection rod 5 is installed on the telescopic end of the hydraulic cylinder 4. A pressure sensor is provided on the detection rod 5.

[0041] A rotating shaft 6 is rotatably connected to the frame 1. The rotating shaft 6 is fixedly connected to the rotating disk 27. The rotating shaft 6 drives the rotating disk 27 to rotate around the center.

[0042] The output of the drive motor 7 drives the rotating shaft 6 to rotate via gear transmission.

[0043] Both the hydraulic cylinder 4 and the detection rod 5 are positioned above the fixed structure 2.

[0044] Working principle: When testing the bulb, the bottom of the bulb is first placed between 29. Under the elastic force of 210, the bottom of the bulb is initially fixed. Then, the output end of 7 drives 6 to rotate through gear transmission. 6 drives 27 to rotate. Then, under the limiting action of 28 on 26, 23 moves along 22, causing 24 to drive 211 to move inward, clamping and fixing the middle of the bulb. The bulb is then clamped and stabilized. Then, 4 is activated. The telescopic end of 4 drives 5 to move downward. The pressure sensor at the end of 5 measures the compressive force on the top of the bulb, detecting the magnitude of the compressive force that the bulb can withstand, thus completing the test of the bulb's compressive strength.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
