[0024] The utility model is further described in detail in combination with the embodiment of the drawings.

[0025] As shown in the drawings, Figures 1-6 The adhesive tape assembly in the embodiment includes an adhesive tape body 1 in the shape of a strip, the adhesive tape body 1 includes an auxiliary adhesive tape segment 14, a first adhesive tape segment 11, a second adhesive tape segment 12 and a third adhesive tape segment 13 distributed in sequence along the length direction of the adhesive tape body 1, and the auxiliary adhesive tape segment 14, the first adhesive tape segment 11, the second adhesive tape segment 12 and the third adhesive tape segment 13 are all provided with a base material, an adhesive layer arranged on the back surface of the base material and a bottom paper arranged on the back surface of the adhesive layer. The base material, the adhesive layer and the bottom paper in the embodiment all adopt the prior art, and the specific structure of the double-sided adhesive tape can be referred to, which will not be described here.

[0026] The auxiliary adhesive tape segment 14 is provided with a through hole 141 for the third adhesive tape segment 13 to pass through, as Figure 1 ​As shown, in this embodiment, the through hole 141 is provided near the connection between the auxiliary tape segment 14 and the first tape segment 11.

[0027] The adhesive layer of the first tape segment 11 is used to adhere to the surface to be joined. The substrate surface of the first tape segment 11 is provided with an indicator unit 111 for indicating the adhesion position of the third tape segment 13, such as... Figure 1 As shown, in this embodiment, the indicator unit 111 is an indicator line (dashed line) extending along the width direction of the first tape segment 11. This indicator line clearly indicates the placement of the third tape segment 13, facilitating operation by the worker.

[0028] The tape body 1 is arranged around the surface to be joined, and the adhesive layer of the third tape segment 13 is adhered to the substrate surface of the first tape segment 11. The tape body 1 has a pulling member 2 on one side adjacent to the third tape segment 13 for pulling the backing paper of the second tape segment 12. To achieve the pulling of the backing paper of the second tape segment 12, the backing paper of the second tape segment 12 has a backing paper flange 121 at one end near the first tape segment 11. The pulling member 2 is connected to the backing paper flange 121, and to ensure smooth pulling of the backing paper of the second tape segment 12, the pulling member 2 consists of at least two pull cords, each extending along the length of the second tape segment 12. Figure 2 and Figure 3 As shown, there are two pull ropes in this embodiment.

[0029] like Figure 2 As shown, the width of the third tape segment 13 is smaller than the width of the second tape segment 12, and the third tape segment 13 is connected to the center of the side of the second tape segment 12. This arrangement places the two pull ropes at opposite ends of the third tape segment 13, preventing positional interference between the pull ropes and the third tape segment 13.

[0030] Since the auxiliary tape segment 14, the first tape segment 11, and the third tape segment 13 only serve a positioning function to improve the fixing effect of the tape assembly, the second tape segment 12 is actually the one that plays a connecting role. Therefore, the length of the second tape segment 12 is greater than the length of the first tape segment 11. In this embodiment, the length of the second tape segment 12 can be determined according to actual needs.

[0031] In this embodiment, the assembly process of the tape body 1 is as follows:

[0032] Will Figure 4 Peel off the backing paper of the first tape segment 11 and attach the adhesive layer of the first tape segment 11 to the surface to be joined.

[0033] Then, the second tape segment 12 is positioned around the surface to be joined, so that it is as follows: Figure 5As shown, the third adhesive tape segment 13 is inserted into the via hole 141 from the back of the auxiliary adhesive tape segment 14 until one end of the third adhesive tape segment 13 reaches the indicated line on the substrate surface of the first adhesive tape segment 11, at which time the third adhesive tape segment 13 is in a tensioned state (the position of the indicated line in the tensioned state can be confirmed experimentally), and the second adhesive tape segment 12 is in a non-sticking state. Figure 6 As shown, the third adhesive tape segment 13 is inserted into the via hole 141 from the back of the auxiliary adhesive tape segment 14 until one end of the third adhesive tape segment 13 reaches the indicated line on the substrate surface of the first adhesive tape segment 11, at which time the third adhesive tape segment 13 is in a tensioned state (the position of the indicated line in the tensioned state can be confirmed experimentally), and the second adhesive tape segment 12 is in a non-sticking state. Figure 6 As shown, the third adhesive tape segment 13 is inserted into the via hole 141 from the back of the auxiliary adhesive tape segment 14 until one end of the third adhesive tape segment 13 reaches the indicated line on the substrate surface of the first adhesive tape segment 11, at which time the third adhesive tape segment 13 is in a tensioned state (the position of the indicated line in the tensioned state can be confirmed experimentally), and the second adhesive tape segment 12 is in a non-sticking state.

[0034] As shown, the third adhesive tape segment 13 is inserted into the via hole 141 from the back of the auxiliary adhesive tape segment 14 until one end of the third adhesive tape segment 13 reaches the indicated line on the substrate surface of the first adhesive tape segment 11, at which time the third adhesive tape segment 13 is in a tensioned state (the position of the indicated line in the tensioned state can be confirmed experimentally), and the second adhesive tape segment 12 is in a non-sticking state. Figure 6 As shown, the third adhesive tape segment 13 is inserted into the via hole 141 from the back of the auxiliary adhesive tape segment 14 until one end of the third adhesive tape segment 13 reaches the indicated line on the substrate surface of the first adhesive tape segment 11, at which time the third adhesive tape segment 13 is in a tensioned state (the position of the indicated line in the tensioned state can be confirmed experimentally), and the second adhesive tape segment 12 is in a non-sticking state.

[0035] Finally, the backing paper of the auxiliary adhesive tape segment 14 is removed, and the auxiliary adhesive tape segment 14 is attached to the second adhesive tape segment 12, thereby completing the assembly of the adhesive tape assembly.

[0036] The application also relates to a connection structure of an air outlet cover and a smoke exhaust pipe, and the contact surface of the air outlet cover and the smoke exhaust pipe is the surface to be connected.

[0037] The preferred embodiments of the application are described above, it should be noted that those skilled in the art can make some improvements and refinements without departing from the technical principles of the application, and these improvements and refinements should also be considered as falling within the protection scope of the application.
