Description
Technical Field
[0001] This utility model relates to the field of breaking force clamping technology, specifically a snap-on breaking force clamping device. Background Technology
[0002] In the LED industry, there is a wide variety of LED bracket models, including 2835, 3528, 3014, 4014, 3535, 3030, and 5050. Due to differences in the materials used by different manufacturers, the toughness of LED brackets varies. To accurately determine the toughness of the bracket, a breaking force tester is currently used for destructive testing. The existing traditional testing method uses a fixed-structure fixture, which requires a separate fixture for each bracket model. During use, the LED bracket is placed in the groove of the corresponding fixture, secured with a cover plate, and then placed in the breaking force tester. When changing the LED bracket model being tested, the fixture and cover plate need to be replaced. As the number of LED bracket models increases, the number of corresponding fixtures required also increases, leading to a significant increase in fixture costs. At the same time, frequent fixture replacements also reduce testing efficiency.
[0003] Therefore, a snap-fit breaking force clamp is proposed to solve the problems mentioned above. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a snap-fit breaking force clamp. By setting an adjustable lower clamp and upper clamp structure, the width of the storage slot can be flexibly adjusted to adapt to the width of different LED bracket models. It eliminates the need for frequent replacement of the entire clamp; simply adjusting the width of the storage slot and selecting the appropriate filling block can accommodate various LED bracket models. This reduces the number of clamps required, lowers clamp equipment costs, avoids frequent clamp replacements, and improves testing efficiency, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a test platform, a lower clamp, and an upper clamp. The lower clamp is placed on the upper surface of the test platform. A storage groove is formed on the upper surface of the lower clamp. A lower fixed block is provided on one side of the storage groove, and a lower movable block is provided on the other side of the storage groove. One end of multiple lower movable blocks is connected to a first slider. A first lead screw is provided on one side of the lower clamp. One end of the first lead screw is inserted into the first slider and threadedly engaged with it. An upper fixed block is provided on the lower surface of the upper clamp. A second slider is slidably connected inside the upper clamp. The second slider is fixedly connected to an upper movable block. A filler block is provided between the upper fixed block and the upper movable block. A second lead screw is threadedly engaged on one side of the second slider.
[0006] Preferably, the end of the first lead screw away from the first slider is rotatably connected to the lower clamp via a bearing.
[0007] Preferably, the other end of the second lead screw is rotatably connected to the upper clamp via a bearing.
[0008] Preferably, a spring is provided between the end of the first slider away from the first lead screw and the lower clamp.
[0009] Preferably, a second spring is provided between the end of the second slider away from the second lead screw and the upper clamp.
[0010] Preferably, the upper surface of the lower clamp is provided with a plurality of guide rods, and the guide rods are slidably connected to the upper clamp.
[0011] Preferably, a first groove is provided on one side of the lower clamp near the first slider, and the contact surface of the first slider and the lower clamp is inserted into the first groove and slidably connected with the first groove.
[0012] Compared with the prior art, this utility model provides a snap-fit breaking force clamp, which has the following beneficial effects:
[0013] 1. By setting adjustable lower and upper clamp structures, the width of the storage slot can be flexibly adjusted to adapt to the width of different LED bracket models.

[0023] 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.
[0024] Example:
[0025] Please see Figure 1 - Figure 7This embodiment of a snap-fit breaking force clamp includes a test bench 1, a lower clamp 2, and an upper clamp 3. The lower clamp 2 is placed on the upper surface of the test bench 1. A storage groove 4 is provided on the upper surface of the lower clamp 2. A lower fixing block 5 is provided on one side of the storage groove 4, and a lower moving block 6 is provided on the other side. One end of multiple lower moving blocks 6 is connected to a first slider 7. A first groove 17 is provided on the side of the lower clamp 2 near the first slider 7. The contact surface of the first slider 7 with the lower clamp 2 is inserted into the first groove 17 and slidably connected with the first groove 17. A first lead screw 12 is provided on one side of the lower clamp 2. The end of the first lead screw 12 away from the first slider 7 is rotatably connected to the lower clamp 2 through a bearing. The other end of the lead screw 12 is inserted into the slider 7 and threadedly connected to it. A spring 15 is provided between the end of the slider 7 away from the lead screw 12 and the lower clamp 2. When the lead screw 12 is rotated, it pushes the slider 7 to move within the groove 17. The slider 7 drives the lower moving block 6 to move, thereby changing the width of the storage slot 4. The spring 15 abuts against the slider 7, making the slider 7 and the lead screw 12 in tight contact, preventing the lower moving block 6 from shaking during movement and ensuring stable movement of the lower moving block 6. This allows for precise adjustment of the width of the storage slot 4 according to the required LED bracket width.
[0026] The upper clamp 3 has an upper fixed block 8 on its lower surface. A second slider 9 is slidably connected inside the upper clamp 3. An upper moving block 10 is fixedly connected to the second slider 9. A filler block 11 is provided between the upper fixed block 8 and the upper moving block 10. A second lead screw 13 is threadedly connected to one side of the second slider 9. The other end of the second lead screw 13 is rotatably connected to the upper clamp 3 through a bearing. A second spring 16 is provided between the end of the second slider 9 away from the second lead screw 13 and the upper clamp 3. The lower clamp 2 has multiple guide rods 14 on its upper surface. The guide rods 14 are slidably connected to the upper clamp 3. When adjusting the upper clamp 3, select a suitable filling block 11 according to the width of the LED bracket (the width of different models of filling blocks 11 is set to differ by 0.5MM). Rotate the second lead screw 13, which drives the second slider 9 to slide. The second slider 9 drives the upper moving block 10 to move, clamping the filling block 11. Then, place the upper clamp 3 on the upper surface of the lower clamp 2. The guide rod 14 guides the upper clamp 3, so that the upper fixing block 8, the filling block 11 and the upper moving block 10 are accurately inserted into the placement slot 4, thereby fixing the LED bracket.
[0027] The working principle of the above embodiment is as follows: by rotating the first lead screw 12, the first lead screw 12 is threadedly connected to the first slider 7, which drives the first slider 7 to move in the first slide groove 17, thereby causing the lower moving block 6 to move closer to or further away from the lower fixed block 5, adjusting the width of the placement groove 4. By rotating the second lead screw 13, the second lead screw 13 is threadedly connected to the second slider 9, which drives the second slider 9 to slide, causing the upper moving block 10 to move to clamp the filling block 11. Together with the upper fixed block 8, the upper clamp 3 fixes the filling blocks 11 of different widths.
[0028] When in use, place the lower clamp 2 on the test table 1 of the breaking force machine, adjust the width of the storage slot 4 according to the LED bracket model and select a suitable filling block 11, put the LED bracket into the storage slot 4, fix it with the upper clamp 3, and use the lead screw of the breaking force machine to drive the test head to perform a breaking force test on the LED bracket.
