Specifically, during use, first fix the housing 21 in the groove 11, then snap the combined cover into the fixing hole 22 on the upper end face of the housing 21 (insert the combined cover into the housing 21 through the through hole 23, and then snap it into the fixing hole 22), hang the pull cover assembly on the combined cover, and turn on the tensile tester to test the opening force of the combined cover. For combined covers of the same size and type, simply snap the combined cover into the fixing hole 22, and then connect the pull cover assembly to the combined cover. The operation is very efficient and convenient, which can effectively shorten the testing cycle of the opening force of the combined cover. Furthermore, for combined covers of different sizes and types, only the corresponding housing 21 and the corresponding pull cover assembly need to be replaced, making the operation even more convenient and efficient.

[0024] In this embodiment, the base 10 has multiple first limiting holes 12 on its side wall, and the lower side wall of the housing 21 has a second limiting hole 24. A limiting rod 14 passes through both the first limiting hole 12 and the second limiting hole 24. The base 10 has multiple threaded holes 13 on its side wall, and an adjusting bolt 15 is threaded into each threaded hole 13. The adjusting bolt 15 abuts against the outer wall of the housing 21. Specifically, after the housing 21 is placed in the groove 11, the limiting rod 14 is passed through the first limiting hole 12, the second limiting hole 24, and the first limiting hole 12 in sequence through the side wall of the base 10, thereby fixing the housing 21 in the groove 11 and preventing the housing 21 from coming out of the groove 11 during the test. Then, the adjusting bolt 15 is used to press against the side wall of the housing 21 to keep the housing 21 in a vertical state and prevent it from tilting during the test.

[0025] In this embodiment, the pull-out cover assembly is a pull-ring type pull-out cover assembly 32. The pull-ring type pull-out cover assembly 32 includes a first pull rod 321 detachably connected to the connecting rod 31, and a hook 322 located at the lower end of the first pull rod 321. When the pull-ring type combination cover 323 is fixed in the through hole 23, the hook 322 is hooked onto the pull ring 324 of the pull-ring type combination cover 323. Specifically, when testing the pull-ring type combination cover 323, the pull-ring type combination cover 323 is snapped into the fixing hole 22 at the upper end of the housing 21, the first pull rod 321 is connected to the connecting rod 31, and the hook 322 at the lower end of the first pull rod 321 is hooked onto the pull ring 324 of the pull-ring type combination cover 323, and the opening force test can then begin.

[0026] Example 2

[0027] As attached Figure 6 -Appendix Figure 8 As shown, this embodiment provides a multifunctional combination cap opening force testing device. The difference from Embodiment 1 is that the cap assembly in this embodiment is a dual-valve cap assembly 33. The dual-valve cap assembly 33 includes a second pull rod 331 detachably connected to the connecting rod 31, a clamping block 332 located at the lower end of the second pull rod 331, and a first slot 333 located on the lower side of the clamping block 332. When a dual-valve combination cap 337 is fixed in the through hole 23, the top of the dual-valve combination cap 337 is engaged in the first slot 333. Specifically, when testing the opening force of the dual-valve combination cap 337, the dual-valve combination cap 337 is first engaged in the fixing hole 22 on the housing 21. Then, the second pull rod 331 is connected to the fixing rod, and the top of the dual-valve combination cap 337 is engaged in the first slot 333 on the lower side of the clamping block 332, thus starting the opening force test of the dual-valve combination cap 337.

[0028] The dual-valve pull-top assembly 33 in this embodiment also includes a slider 335 fixedly disposed at the lower end of the second pull rod 331, a second slot 334 opened on the upper side of the clamping block 332, and a fastening bolt 336 disposed on the side wall of the clamping block 332; the slider 335 is slidably disposed in the second slot 334, and the fastening bolt 336 abuts against the side wall of the slider 335. Specifically, after the dual-valve combination cap 337 is fixed in the fixing hole 22, it is only necessary to slide the clamping block 332 so that the top of the dual-valve combination cap 337 is inserted into the first slot 333, and at the same time, the slider 335 is also inserted into the second slot 334. Then, the fastening bolt 336 is used to fix the clamping block on the slider 335. This operation is more convenient and can connect the clamping block 332 and the dual-valve combination cap 337 more quickly.

[0029] In this embodiment, the upper surface of the housing 21 is inclined. Specifically, when the upper surface of the housing 21 is inclined, the combined cover is also inclined. At this time, the direction of movement of the cover pull assembly is at a certain angle to the combined cover, which is more in line with the angle of the human body when starting to assemble the cover.

[0030] In summary, the multifunctional combination cap opening force testing device of this utility model first fixes the housing 21 in the groove 11, then snaps the combination cap into the fixing hole 22 on the upper end face of the housing 21, hangs the pull cap assembly on the combination cap, and turns on the tensile tester to test the opening force of the combination cap. For combination caps of the same size and type, it is only necessary to snap the combination cap into the fixing hole 22 and then connect the pull cap assembly to the combination cap. The operation is very efficient and convenient, which can effectively shorten the opening force testing cycle of combination caps. Furthermore, for combination caps of different sizes and types, it is only necessary to replace the corresponding housing 21 and the corresponding pull cap assembly, making the operation even more convenient and efficient.
