[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical means for implementation:

[0006] A double-layer flexible connection ring anti-theft cap with multiple continuous convex steps, which includes a cap body with a spiral thread and an anti-theft ring. The anti-theft ring includes an upper sleeve ring and a lower sleeve ring with the same diameter and thickness. The upper sleeve ring is ring-shaped with a continuous part at the head and tail. The lower sleeve ring is a complete ring. At least one pair of inclined hook parts is arranged on the opposite sides of the lower sleeve ring. The cap body has a plurality of upper continuous convex steps on the lower edge. The lower sleeve ring has a plurality of lower continuous convex steps on the upper edge. The upper continuous convex steps are connected to the upper edge of the upper sleeve ring through upper continuous points, and the lower continuous convex steps are connected to the lower edge of the upper sleeve ring through lower continuous points. The upper connection part is arranged at the head end of the upper sleeve ring, and the lower connection part is arranged at the tail end of the upper sleeve ring. The upper connection part and the lower connection part are vertically staggered. The width of the upper connection part and the lower connection part is not less than the thickness of the lower sleeve ring.

[0007] Further, the number of upper continuous convex steps is 3-8, and the number of lower continuous convex steps is 3-8.

[0008] Further, the upper connecting and disconnecting convex steps are connected to the upper edge of the upper sleeve through 1-3 upper connecting and disconnecting points, and the lower connecting and disconnecting convex steps are connected to the lower edge of the upper sleeve through 1-3 lower connecting and disconnecting points.

[0009] Further, the upper connecting parts are arranged in a circle on the upper layer, and the lower connecting parts are arranged in a circle on the lower layer.

[0010] Further, the upper connecting and disconnecting convex steps are connected to the upper edge of the upper sleeve through 1-3 upper connecting and disconnecting points, and the lower connecting and disconnecting convex steps are connected to the lower edge of the upper sleeve through 1-3 lower connecting and disconnecting points.

[0011] Further, the connecting and disconnecting part is arranged between two adjacent vertical same group connecting and disconnecting convex steps.

[0012] Further, the width of the upper connecting part and the lower connecting part is not less than the thickness of the upper connecting and disconnecting convex step and the lower connecting and disconnecting convex step.

[0013] Further, at least one inclined hook part is arranged on the lower side of the upper connecting part or the lower connecting part.

[0014] The utility model has at least the following advantages:

[0015] 1. The upper sleeve of the anti-theft ring is connected to the connecting and disconnecting ring structure through the connecting and disconnecting part at the head and tail, the lower sleeve is a complete ring structure with a size similar to that of the upper sleeve, and the upper and lower connecting and disconnecting convex steps are arranged towards the upper and lower edges of the upper sleeve, so that the visual effect of the anti-theft cover protruding laterally is avoided, and after the upper sleeve is disconnected at the head and tail, the upper sleeve connects the cover body and the lower sleeve, forms a long connecting part to connect the cover body and the lower sleeve, avoids the loss of the cover body, and reduces the inconvenience caused by the short length of the connecting part.

[0016] 2. Based on the double-layer anti-theft ring as the anti-theft structure, while maintaining the basic anti-theft performance, the upper connecting part and the lower connecting part arranged at the head and tail of the upper sleeve are arranged in a staggered manner and have high structural strength, so that the structural stability part of the upper sleeve is formed, the upper sleeve is deformed instead of being disconnected at the head and tail at the initial stage of twisting the anti-theft cover, the lower sleeve structure with a size similar to that of the upper sleeve is arranged, both are more likely to be twisted and deformed, so that the upper connecting and disconnecting points and the lower connecting and disconnecting points which are relatively weak are disconnected due to the twisting and deformation between the upper sleeve and the lower sleeve, and when the cover body is opened with a small twisting force, the upper and lower connecting and disconnecting convex steps are disconnected relative to the upper sleeve.

[0017] 3. By reasonably arranging the direction of the upper and lower connecting and disconnecting convex steps, i.e. the upper and lower connecting and disconnecting convex steps are arranged corresponding to the cover body and the lower sleeve, the connecting part formed by the upper sleeve after being opened has a relatively smooth surface, and abnormal touch feeling caused by the free swinging and sliding contact of the upper sleeve with the skin when a short straw is used to drink is avoided.

[0022] 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.

[0023] Example

[0024] like Figures 1-4 As shown, a double-layer flexible connecting ring anti-theft cover with multiple connecting steps includes a cover body 10 with a spiral pattern and an anti-theft ring. The anti-theft ring includes an upper ring 11 and a lower ring 12 of the same thickness. The upper ring 11 is a ring connected end to end by connecting parts 13. The lower ring 12 is a complete ring. At least one pair of inclined hooks 14 are provided on opposite sides of the inner edge of the lower ring 12. The lower edge of the cover body 10 is provided with several upper connecting steps 102, and the upper edge of the lower ring 12 is provided with several lower connecting steps. The upper connecting step 102 is connected to the upper edge of the upper collar 11 through the upper connecting break point 103, and the lower connecting step 122 is connected to the lower edge of the upper collar 11 through the lower connecting break point 123. The upper connecting part 101 is located at the beginning of the upper collar 11, and the lower connecting part 121 is located at the end of the upper collar 11. The upper connecting part 101 and the lower connecting part 121 are arranged vertically and staggered, and the width of the upper connecting part 101 and the lower connecting part 121 is not less than the thickness of the lower collar 12.

[0025] Figure 3The anti-theft ring can be sleeved on the self-standing bag suction nozzle 2, and can play the same anti-theft and cover cooperation effect as similar anti-theft cover products. During the twisting opening process, the plurality of pairs of inclined hook portions 14 arranged on the opposite sides of the inner edge of the lower sleeve ring 12 can be clamped with the stopper part upright wall 21 of the self-standing bag suction nozzle 2, so that the lower sleeve ring 12 is limited and does not rotate relative to the self-standing bag suction nozzle 2, and the cover body 10 rotates relative to the self-standing bag suction nozzle 2 along the inner spiral thread, at this time, the upper and lower continuous convex steps 102 and 122 are relatively displaced in the circumferential direction between the upper edge of the upper sleeve ring 11 and the lower edge of the upper sleeve ring 11, and because the thicknesses of the upper sleeve ring 11 and the lower sleeve ring 12 are the same, the upper sleeve ring 11 and the lower sleeve ring 12 are easily deformed due to the twisting force, so that the upper and lower continuous points 103 and 123 are easily broken due to the twisting force; during the opening process, the continuous part 13 is also broken due to the twisting force, the upper sleeve ring 11 connected by the continuous part 13 is disconnected at the head and tail positions, so after the twisting opening, the utility model can form a general use state, that is, the upper sleeve ring 11 forms a longer connecting piece connecting the cover body 10 and the lower sleeve ring 12. Figure 4

[0026] Because the upper sleeve ring 11 forms a longer connecting piece connecting the cover body 10 and the lower sleeve ring 12, the cover body 10 can be prevented from being lost, and compared with the prior art, the use is more convenient, and the surface of the longer connecting piece formed by the upper sleeve ring 11 is smooth, so that the abnormal touch feeling caused by the free swing of the upper sleeve ring 11 and the sliding contact with the skin when the self-standing bag suction pipe is used to suck the content is avoided.

[0027] In the embodiment, the number of the upper and lower continuous convex steps 102 and 122 is 5, each upper continuous convex step 102 is connected with the upper edge of the upper sleeve ring 11 through an upper continuous point 103, and each lower continuous convex step 122 is connected with the lower edge of the upper sleeve ring 11 through a lower continuous point 123. Through the setting, it can be ensured that the upper sleeve ring 11 has sufficient connection positions at each upper and lower position in the circumferential direction, and the structure of the single continuous point relative to the multiple continuous points has the advantage of being more easily broken when subjected to the twisting force; of course, through the reasonable reduction of the number of the upper and lower continuous convex steps 102 and 122, and the setting scheme of increasing the number of the upper and lower continuous points 103 and 123, excellent technical effects can also be obtained.

[0028] ​In the embodiment, the upper connecting portions 101 are arranged in a circle on the upper layer, the lower connecting portions 121 are arranged in a circle on the lower layer, the upper connecting and disconnecting convex steps 102 are vertically arranged in alignment with each other, the lower connecting and disconnecting convex steps 122 are vertically arranged in alignment with each other, and the vertically arranged connecting and disconnecting convex steps form a vertical group. Preferably, the connecting and disconnecting portion 13 is arranged between two adjacent vertically arranged connecting and disconnecting convex steps. Through the arrangement, the visual regularity of the product can be improved, and when the product is twisted, the upper connecting and disconnecting convex steps 102, the lower connecting and disconnecting convex steps 122, the upper sleeve 11 and the connecting and disconnecting portion 13 can bear force uniformly.

[0029] In the embodiment, the width of the upper connecting portion 101 and the lower connecting portion 121 is not less than the thickness of the upper connecting and disconnecting convex step 102 and the lower connecting and disconnecting convex step 122. Through the arrangement, the visual regularity can be improved, the structural stability of the lower sleeve 12 at the adjacent position can be improved, the deformation position of the lower sleeve 12 during twisting is concentrated between two adjacent lower connecting portions 121, the overall structural stability of the upper sleeve 11 adjacent to the upper connecting portion 101 and the lower connecting portion 121 is relatively strong, and the synchronization of the upper sleeve 11 and the upper connecting and disconnecting convex step 102 and the lower connecting and disconnecting convex step 122 can be improved.

[0030] In the embodiment, at least one inclined hook portion 14 is arranged on the lower side of the upper connecting portion 101 or the lower connecting portion 121. Through the arrangement, when the cap body 10 and the self-standing bag suction nozzle 2 are twisted, the inclined hook portion 14 on the lower side of the upper connecting portion 101 or the lower connecting portion 121 is adjacent to the connecting and disconnecting portion 13, the upper sleeve 11 is more likely to be disconnected along the connecting and disconnecting portion 13 when force is applied, and the convenience of opening the cap body 10 can be further improved.
