Description

Technical Field

[0001] This utility model relates to the field of pull-out force detection technology, and specifically to an auxiliary device for pull-out force detection. Background Technology

[0002] In bottle cap pull-out force testing, the lack of a connection or functional point between the smooth or curved surface of the bottle cap and the testing device makes it difficult to measure the pull-out force. Current testing methods involve attaching tape to the bottle cap to create a handle for connection with the testing device. However, this method is prone to tape breakage or insecure adhesion during the pull-out force test, leading to inaccurate results. Utility Model Content

[0003] This utility model addresses one of the problems existing in the prior art to a certain extent. Therefore, one objective of this utility model is to provide an auxiliary device for pulling out force, which can effectively test the force required to pull the bottle cap out of the bottle body and facilitate testing.

[0004] The above objective is achieved through the following technical solution: A pull-out force detection auxiliary device includes a pull-out structure and an adjusting component. The pull-out structure includes a first elastic rod and a second elastic rod, with a gap between the first elastic rod and the second elastic rod. The adjusting component is disposed between the first elastic rod and the second elastic rod, and the first elastic rod and the second elastic rod clamp the adjusting component through elastic force. The adjusting component is used to adjust the size of the gap between the first elastic rod and the second elastic rod. A first actuating part is provided on the first elastic rod, and a second actuating part is provided on the second elastic rod.

[0005] As a further improvement of this utility model, the first functional part is formed by protruding outward at the lower end of the first elastic member, and the second functional part is formed by protruding outward at the lower end of the second elastic member.

[0006] As a further improvement of this utility model, a first load-bearing surface is formed at the upper end face of the first functional part, and a second load-bearing surface is formed at the upper end face of the second functional part.

[0007] As a further improvement of this utility model, the cross-section of the first functional part gradually increases from bottom to top; and the cross-section of the second functional part gradually increases from bottom to top.

[0008] As a further improvement of this utility model, it also includes a connector, wherein the first elastic rod and the second elastic rod are an integral structure, and a connecting hole is formed between the first elastic rod and the second elastic rod. The connector connects the pull-out structure to the tensile testing device through the connecting hole.

[0009] As a further improvement of this utility model, the cross-section of the adjusting member gradually decreases from one end to the other.

[0010] As a further improvement of this utility model, the adjusting member is detachably connected to the pull-out structure.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model proposes an auxiliary device for detecting pull-out force. The pull-out structure is inserted into the bottle body. The pull-out structure is connected to the inner wall of the liquid outlet of the bottle cap through its first and second working parts.

Detailed Implementation

[0013] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0014] like Figure 1-6A pull-out force detection auxiliary device includes a pull-out structure 1 and an adjusting member 2. The pull-out structure 1 includes a first elastic rod 11 and a second elastic rod 12, with a gap 13 between the first elastic rod 11 and the second elastic rod 12. The adjusting member 2 is disposed between the first elastic rod 11 and the second elastic rod 12. The adjusting member 2 is clamped by the elastic force between the first elastic rod 11 and the second elastic rod 12, and the size of the gap 13 between the first elastic rod 11 and the second elastic rod 12 is adjusted by the adjusting member 2. A first actuating part 111 is provided on the first elastic rod 11, and a second actuating part 121 is provided on the second elastic rod 12.

[0015] This invention proposes an auxiliary device for detecting pull-out force. A first elastic rod 11 and a second elastic rod 12 are inserted into the bottle to be tested through the central outlet of the bottle cap. An adjusting member 2 is positioned between the first and second elastic rods 11 and 12, adjusting the distance 13 between them. This distance ensures that the distance between the first and second acting parts is greater than the diameter of the outlet. At this point, the first and second acting parts can abut against the inner wall of the bottle cap's outlet. When an external force pulls the pull-out structure 1 upwards, the first and second acting parts 111 and 121 act on the bottle cap, pulling it out of the bottle. Since the first and second acting parts act directly on the bottle opening of the cap, this avoids the situation where the pull-out structure only interacts with the handle formed by the adhesive tape on the cap. This ensures stable and smooth testing and guarantees the accuracy of the test results.

[0016] In some embodiments, the liquid outlet is formed by a recess in the bottle cap.

[0017] In some embodiments, a torsion spring is provided between the first elastic rod and the second elastic rod, such that there is an elastic force bringing the first elastic rod and the second elastic rod closer together, thereby keeping the first elastic rod and the second elastic rod close to each other. The adjusting member can be clamped by the elastic force of the first elastic rod and the second elastic rod bringing them closer together.

[0018] The pull-out structure 1 abuts or tightly engages with the inner wall of the liquid outlet at the bottle cap via its first working part 111 and second working part 121, and connects the pull-out structure to the tensile testing device. Pulling the pull-out structure 1 upwards will pull the bottle cap out of the bottle body, effectively testing the pull-out force of the bottle cap being pulled out of the bottle body, which is convenient for testing.

[0019] In some embodiments, the outlet is located at the center of the bottle cap.

[0020] In this embodiment, the first and second elastic elements are elastic and will move closer to each other under the action of elastic force. When the adjusting element is not between the first and second elastic elements, under the action of elastic force between the first and second elastic elements, the distance between the first and second elastic elements will be smaller than the diameter of the liquid outlet at the bottle cap, so the first and second elastic elements can extend into the bottle cap through the liquid outlet.

[0021] In this embodiment, the first working part 111 is formed by protruding outward at the lower end of the first elastic rod 11 and at the end face away from the second elastic rod; the second working part 121 is formed by protruding outward at the lower end of the second elastic rod 12 and at the end face away from the first elastic rod.

[0022] In this embodiment, a first load-bearing surface 112 is formed on the upper end face of the first functional part 111, and a second load-bearing surface 122 is formed on the upper end face of the second functional part 121. The first load-bearing surface 112 and the second load-bearing surface 122 abut against the inner wall of the liquid outlet of the bottle cap.

[0023] In some embodiments, a first load-bearing groove is formed at the first load-bearing surface 112 and a second load-bearing groove is formed at the second load-bearing surface 122. That is, when the first load-bearing surface 112 and the second load-bearing surface 122 abut against the inner wall of the bottle cap outlet, they can be engaged with the retaining ring at the bottle cap outlet through the first load-bearing groove and the second load-bearing groove, so as to avoid the phenomenon that the inner wall of the outlet slips off at the first load-bearing surface and the second load-bearing surface due to the smooth surface of the first load-bearing surface and the second load-bearing surface.

[0024] In some embodiments, the first load-bearing groove and the second load-bearing groove are arc-shaped grooves.

[0025] In some embodiments, protrusions are provided on the first and second load-bearing surfaces to increase the friction between the first and second load-bearing surfaces.

[0026] The cross-section of the first functional part 111 gradually increases from bottom to top, and the cross-section of the second functional part 121 also gradually increases from bottom to top. In this embodiment, the lower ends of the first functional part 111 and the second functional part 121 have narrower cross-sections, facilitating their insertion into the inside of the bottle cap through the liquid outlet. The upper surfaces of the first functional part 111 and the second functional part 121 are wider, facilitating their contact with the inner wall of the liquid outlet of the bottle cap, and when the first functional part 111 and the second functional part 121 contact the bottle cap, there is a larger contact area with the retaining ring at the inner wall of the liquid outlet of the bottle cap.

[0027] In some embodiments, the first functional portion 111 and the second functional portion 121 have a tapered structure that is narrow at the bottom and wide at the top.

[0028] In some embodiments, the first elastic rod 11 includes a first extension and a first adjustment portion, the first extension being at the lower end of the first elastic rod 11, and the first adjustment portion being at the middle or upper end of the first elastic rod 11. The second elastic rod 12 includes a second extension and a second adjustment portion. The second extension is located at the lower end of the second elastic rod 12, and the second adjustment portion is located at the middle or upper end of the second elastic rod 12.

[0029] The first protrusion and the second protrusion are used to extend into the bottle cap, and the first adjustment part and the second adjustment part are used to clamp the adjustment member 2 to adjust the size of the distance 13 between the first elastic rod 11 and the second elastic rod 12.

[0030] The first elastic rod 11 and the second elastic rod 12 are disposed opposite to each other. In some embodiments, a first receiving portion 110 is formed by protruding outward from the first elastic rod 11 toward the second elastic rod 12, that is, a first receiving portion 110 is formed by protruding from the first adjusting portion; A second receiving portion 120 is formed by protruding outward from the second elastic rod 12 toward the first elastic rod 11, that is, a second receiving portion 120 is formed by protruding at the second adjusting portion; The first receiving part and the second receiving part are also arranged opposite to each other so as to receive the adjusting member 2 through the first receiving part and the second receiving part.

[0031] It also includes a connector 3, wherein the first elastic rod 11 and the second elastic rod 12 are integral structures, and a connecting hole 14 is provided between the first elastic rod 11 and the second elastic rod 12. The connector 3 connects the pull-out structure to the tensile testing device through the connecting hole 14.

[0032] Connect connector 3 to the tensile testing device, and pull out structure 1 upwards to pull the bottle cap out of the bottle body. This effectively tests the force required to pull the bottle cap out of the bottle body, making testing convenient.

[0033] In this embodiment, the connector 3 includes a tough steel ring. During the pull-out force test, the pull-out structure 1 is connected to the tensile testing device via the connector 3, the hook on the tensile testing device is connected to the tough steel ring, and the tough steel ring is connected to the pull-out structure 1.

[0034] The adjusting member 2 has a cross-section that gradually decreases from one end to the other. In this embodiment, the adjusting member 2 is a strip-shaped member, and the cross-section of the strip-shaped member gradually decreases from one end to the other. By placing the adjusting member 2 between the first elastic rod 11 and the second elastic rod 12, the distance between the first elastic rod 11 and the second elastic rod 12 can be adjusted by adjusting the position of the adjusting member between the first elastic rod 11 and the second elastic rod 12.

[0035] In some embodiments, the adjusting member is provided with a plurality of slots 29, which extend vertically and can be used to engage with the first elastic rod and the second elastic rod. That is, when the adjusting member is positioned between the first elastic rod and the second elastic rod, the first elastic rod and the second elastic rod engage with the slots on the adjusting member to stabilize the distance between the first elastic rod and the second elastic rod.

[0036] In some embodiments, the slot includes a first slot 292 and a second slot 291, the first slot being located at one end face of the adjusting member facing the first elastic rod, and the second slot being located at one end face of the adjusting member facing the second elastic rod 12.

[0037] In some embodiments, the adjusting member includes multiple stepped sections. For example, the adjusting member includes three stepped sections, which are, from left to right, a first stepped section, a second stepped section, and a third stepped section. The first stepped section is formed by narrowing at the left end of the adjusting member; the second stepped section is formed by narrowing inward at the middle of the adjusting member; and the third stepped section is formed by narrowing inward at the right end of the adjusting member.

[0038] The adjusting member 2 is detachably connected to the pull-out structure 1. In this embodiment, the adjusting member 2 is not fixed to the pull-out structure 1. When it is necessary to adjust the distance 13 between the first elastic rod 11 and the second elastic rod 12 of the pull-out structure 1, the adjusting member 2 is installed between the first elastic rod 11 and the second elastic rod 12. When no adjustment is needed, or when the pull-out structure 1 is not used, the adjusting member 2 can be removed from the pull-out structure 1 for easy storage.

[0039] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
