[0001] This utility model relates to a tape breakage indicator device. Background Technology

[0002] Existing tape breakage marking devices use more than two components, have a complex structure, some parts exceed the volume of the tape itself, require secondary operation, and have a single function. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tape breakage indicator device.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution:

[0005] This utility model includes an adhesive tape, characterized in that a fixing ring and an indicator ring are sequentially arranged from the outside to the inside on the inner ring of the adhesive tape.

[0006] The fixing ring includes an outer ring body and a fixing ring limiting card disposed on one side of the outer ring body. The inner circumference of the outer ring body is provided with an outer semi-circular protrusion, and the outer circumference of the outer ring body is provided with a fixing limiting protrusion.

[0007] The indicator ring includes an inner ring body, a fixed boss, and an indicator ring limiting card. The outer circumference of the inner ring body is provided with more than four inner semi-circular protrusions. The fixed boss is fixed to the lower end of the inner ring body in a circumferential array. The indicator ring limiting card is provided with a drive handle.

[0008] The inner ring is embedded inside the outer ring, the inner semi-circular protrusion is adapted to the outer semi-circular protrusion, and the fixing boss is located at the lower end of the outer semi-circular protrusion.

[0009] The fixed limiting protrusion is in the shape of a trumpet.

[0010] The fixed ring limiter is equipped with a measuring scale, which is an angle measuring scale and a length measuring scale, and the drive handle is equipped with an arrow mark.

[0011] The positive effects of this utility model are as follows:

[0012] (1) The design is extremely simple, with only two parts. The device is small in size, low in cost, does not take up extra space, and has an attractive appearance.

[0013] (2) It is not easily affected by external forces. The device is installed inside the tape core, which effectively reduces the impact of falling or squeezing. In addition, the indicator ring has damping when rotating, which can effectively prevent the impact caused by accidental contact.

[0014] (3) The operation is simple and only requires conventional operation to drive the indicator device without additional secondary operation. Attached Figure Description

[0019] Appendix Figure 5 This is a schematic diagram of the second usage state of this utility model. Detailed Implementation

[0020] As attached Figure 1-5 As shown, this utility model includes an adhesive tape 1, characterized in that a fixing ring 2 and an indicator ring 3 are sequentially arranged on the inner ring of the adhesive tape 1 from the outside to the inside.

[0021] The fixing ring 2 includes an outer ring body 2-1 and a fixing ring limiting card 2-2 disposed on one side of the outer ring body 2-1. The inner circumference of the outer ring body 2-1 is provided with an outer semi-circular protrusion 2-3, and the outer circumference of the outer ring body 2-1 is provided with a fixing limiting protrusion 2-4.

[0022] The indicator ring 3 includes an inner ring body 3-1, a fixed boss 3-2, and an indicator ring limiting card 3-4. The outer circumference of the inner ring body 3-1 is provided with more than four inner semi-circular protrusions 3-3. The fixed boss 3-2 is fixed to the lower end of the inner ring body 3-1 in a circumferential array. The indicator ring limiting card 3-4 is provided with a drive handle 3-5.

[0023] The inner ring 3-1 is embedded inside the outer ring 2-1, the inner semi-circular protrusion 3-3 is adapted to the outer semi-circular protrusion 2-3, and the fixing boss 3-2 is located at the lower end of the outer semi-circular protrusion 2-3.

[0024] The functions and principles of the two main components of this utility model are as follows:

[0025] (1) Fixing ring: Its outer ring size is 76mm, which is suitable for the inner diameter of the core of conventional tape. The surface is treated with serrated anti-slip treatment and is designed in a conical shape to facilitate embedding into the tape core. The inner ring consists of an inner ring mounting groove, a damping protrusion, and an indicator ring fixing groove from the outside to the inside. The damping protrusion consists of 180 evenly distributed 1.2mm semicircles on the inner ring, which cooperate with the four semicircular protrusions on the indicator ring to provide a certain resistance to the rotation of the indicator ring and prevent it from being disturbed by other external forces in non-practical state.

[0026] (2) Indicator ring: From the outside to the inside, it consists of a mounting boss, a damping protrusion, and a fixing boss. A "ginkgo leaf" shaped drive handle is designed inside the ring to facilitate finger operation, and an indicator arrow is provided on the handle. The damping protrusion is designed as four evenly distributed 1.2mm semi-circular protrusions, which work together with the fixing ring to achieve a damping effect.

[0027] The assembly process of this utility model is as follows: the fixing ring is put into the indicator ring, and the assembly of the device is completed when the fixing boss of the indicator ring falls into the fixing groove.

[0028] When not using the tape: Install the assembled device into the tape core, manually locate the break point from the last use of the tape, and then rotate the indicator arrow to that break point. Next time you use it, simply locate the break point indicated by the arrow.

[0029] When using this invention with tape: Hold your fingers between the handle of the indicator ring and place your thumb on the tape surface. Locate the break and pull the tape to the desired length. As you pull, the tape rolls in your palm, but the indicator ring will not roll with the tape due to the pressure of your fingers; its arrow will always point towards the vicinity of the tape separation point. Once the desired length is reached, cut the tape at the separation point with scissors. The indicator arrow will then remain near the separation point, ready for the next use.

[0030] The fixed limiting protrusions 2-4 are in the shape of a trumpet.

[0031] The fixed ring limiter 2-2 is equipped with a measuring scale, which is an angle measuring scale and a length measuring scale. The drive handle 3-5 is equipped with an arrow mark. Based on the special number of turns and the change of the arrow mark, the length of the pulled-out tape can be estimated according to the remaining thickness of the tape, avoiding waste and adhesion problems caused by measuring the stretched part.
