[0021] In the drawing: main body 1, upper cover part 2, welding line 3, first crease 4, second crease 5, third crease 6, fourth crease 7, easy-to-open indentation 8, triangular notch 9, cover sheet 10, strip-shaped thickened part 11, circular thickened part 12. DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] REFERENCE Figures 1-8, PVC heat shrink box, including main body 1 and upper cover 2, upper cover 2 is arranged on the upper end of main body 1, the upper end of upper cover 2 is closed by welding line 3, welding line 3 can not only prevent the PVC heat shrink box from loosening, but also play a sealing role, prevent water, foreign matter and the like from entering its inside from the upper end of upper cover 2. The lower end of main body 1 is in a closed state, which ensures that dust does not easily enter the inside during transportation, and does not affect the quality of the PVC heat shrink box subsequently, and when used, the lower end of the PVC heat shrink box only needs to be cut open to be used. First crease 4 is arranged between main body 1 and upper cover 2, two second creases 5 intersecting at one end are arranged at both ends of upper cover 2, a plurality of third creases 6 are arranged on the surface of the periphery of main body 1, fourth crease 7 is arranged in the center of the surface of both sides of main body 1 and upper cover 2, and main body 1 and upper cover 2 include a folded state and an opened state. The upper cover 2 in the folded state is a trapezoid, facilitating opening of the PVC heat shrink box. The main body 1 in the folded state is an inverted trapezoid, facilitating folding of the lower part of the third crease 6 into the inside of the main body 1.

[0024] Easily opened indentation 8 is arranged at the lower part of main body 1.

[0025] Triangular notch 9 is arranged at one end of easily opened indentation 8.

[0026] Covering sheet 10 is arranged at both sides of triangular notch 9. The covering sheet 10 is arranged to prevent the PVC heat shrink box from being torn along the triangular notch 9 by mistake.

[0027] A plurality of strip-shaped thickened portions 11 are arranged on the front and rear surfaces of main body 1. The strip-shaped thickened portions 11 are arranged to play a pressure-resistant role during transportation and a reinforcing role during use.

[0028] A plurality of circular thickened portions 12 are arranged on the front and rear surfaces of main body 1. The circular thickened portions 12 are arranged to play a pressure-resistant role during transportation and a reinforcing role during use.

[0029] Working principle: during transportation, folding can be performed along second crease 5 and fourth crease 7 to form an initial folding state as shown in Figure 1 , and transportation is performed. When used, the lower end of main body 1 is opened by tearing along easily opened indentation 8 through triangular notch 9, and then the PVC heat shrink box is in a fully opened state by inserting a hand into the inside of main body 1, as shown in Figure 5 and 7Then the circuit or key components are wrapped, and then hot air is blown, so that the circuit to be protected is wrapped tightly, and the waterproof effect is achieved. When different specifications of the PVC heat shrink box are needed, by cutting along the third crease 6, different specifications of the PVC heat shrink box can be obtained, and by folding the lower part of the third crease 6 into the main body 1, different specifications of the PVC heat shrink box can also be obtained, which can be suitable for circuits or key components of different sizes, and the application range is relatively wide.

[0030] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical scheme and the inventive concept of the present application, which should be covered within the protection scope of the present application.
