[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] 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.

[0020] like Figures 1 to 3As shown, this utility model proposes a lamp holder ear tension testing mechanism, including: a working platform 1, a fixture, two sets of horizontal tension testing units and one set of vertical tension testing units.

[0021] The fixture is located at the center of the work platform 1 and is used to place the lamp tube 2 to be tested. Two sets of horizontal tensile testing units are located on both sides of the fixture and are used to simultaneously perform horizontal tensile testing on the hanging ears 3 of the lamp tube 2 to be tested. The vertical tensile testing unit is located above the fixture and is used to perform vertical tensile testing on the hanging ears 3 of the lamp tube 2 to be tested.

[0022] like Figure 3 As shown, in this embodiment, the lamp tube 2 is cylindrical, and grooves are provided on both sides of the lamp tube 2. Hanging ears 3 are respectively provided in the grooves on both sides of the lamp tube 2.

[0023] In this embodiment, the horizontal tension testing units located on both sides of the fixture simultaneously perform horizontal tension testing on the lugs 3 of the lamp tube 2 under test. This can avoid uneven force on the lugs 3 on both sides of the lamp tube 2, which could cause them to shift and lead to inaccurate testing.

[0024] Specifically, in this embodiment, the horizontal tensile testing unit includes: an operating lever 4, a first cylinder 5, and a first push rod 6. The operating lever 4 is signal-connected to the first cylinder 5, and the output end of the first cylinder 5 is connected to one end of the push rod. The first cylinder 5 is used to drive the first push rod 6 to move horizontally, so that the hanging lug 3 of the lamp tube 2 under test can be subjected to a horizontal tensile test. In this embodiment, the first push rod 6 is T-shaped.

[0025] It should be noted that, in this embodiment, before conducting a tensile test on the lug 3, the stroke of the first cylinder 5 can be set according to the tensile strength requirement of the lug 3. During the test, when the operating lever 4 is pressed, the first cylinder 5 drives the first push rod 6 to its maximum stroke, where it abuts against the side of the lug 3. When pressure is generated on the lug 3 according to the set force, one test is completed. After the test is completed, the first cylinder 5 resets. This process is repeated a set number of times (e.g., 20 times). If the lug 3 does not break, it indicates that the horizontal tensile strength of the lug 3 is qualified; otherwise, it is unqualified.

[0026] Furthermore, in this embodiment, the up-and-down tensile force testing unit includes a mounting bracket 7, a second cylinder 8, and a second push rod 9, all mounted on the working platform 1. The second cylinder 8 is mounted on the mounting bracket 7, and its output end is connected to the top of the second push rod 9. The second cylinder 8 drives the second push rod 9 to move up and down, performing a up-and-down tensile force test on the hanging lug 3 of the lamp tube 2 under test. The bottom of the second push rod 9 is U-shaped.

[0027] In the same horizontal tensile testing unit, before conducting the tensile test on the lug 3, the stroke of the second cylinder 8 can be set according to the tensile strength requirement of the lug 3. During the test, the second cylinder 8 drives the second push rod 9 to its maximum stroke to abut against the top surface of the lug 3. When pressure is generated on the lug 3 according to the set force, one test is completed. After the test is completed, the second cylinder 8 resets. This is repeated a set number of times (e.g., 20 times). If the lug 3 does not break, it indicates that the tensile strength of the lug 3 in the vertical direction is qualified; otherwise, it is unqualified.

[0028] After the horizontal and vertical tensile tests are completed on the hanging ear 3, the product can be removed and the next cycle can begin to test the hanging ear 3 of the next lamp tube 2.

[0029] The beneficial effects of this utility model lamp holder lug pull force testing mechanism are:

[0030] This utility model, through the above-mentioned technical solution, includes: a working platform, a fixture, two sets of horizontal tensile testing units, and one set of vertical tensile testing units; the fixture is set at the center of the working platform for placing the lamp tube to be tested; the two sets of horizontal tensile testing units are located on both sides of the fixture for simultaneously performing horizontal tensile tests on the lugs of the lamp tube to be tested; the vertical tensile testing unit is set above the fixture for performing vertical tensile tests on the lugs of the lamp tube to be tested, which can improve the efficiency of lamp tube lug tensile testing, and test all surfaces of the lugs to ensure the consistency of test strength and improve test accuracy.
