As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0026] Example one

[0027] Please refer to Figures 1-7 A temperature-sensitive color-changing insulating tape, comprising an insulating tape 10,

[0028] The insulating tape 10 is wound on the plastic ring body 11 for multiple turns, and the insulating tape 10 is arranged in multiple layers and is composed of a heat-sensitive layer 12, a silica gel layer 13 and a self-adhesive layer 14.

[0029] In order to ensure the insulation and mechanical strength of the insulating tape, the silica gel with high temperature resistance, wear resistance and corrosion resistance is selected as the base material, a layer of heat-sensitive material is coated on the upper surface of the silica gel layer 13 as the heat-sensitive layer 12, and the heat-sensitive material can be selected from triarylmethane heat-sensitive material and fluoran heat-sensitive material. When the insulating tape 10 is wound on the bare wire of the electrical equipment, the wire will change color when reaching a certain temperature, thereby playing a warning role. A layer of self-adhesive material is coated on the lower surface of the silica gel layer 13 as the self-adhesive layer 14, and the self-adhesive material can be selected from acrylate pressure-sensitive adhesive and rubber pressure-sensitive adhesive, so as to facilitate winding the insulating tape 10 on the wire.

[0030] The insulating tape is wound on the bare wire (the wire without rubber skin) of the electrical equipment by the self-adhesive layer 14. With the operation of the electrical equipment, the temperature of the wire gradually rises. When the temperature of the wire at the winding position of the insulating tape is too high (for example, higher than 60 DEG C), the tape changes from the original color to white or other colors. When the wire returns to room temperature, the tape will return to the original color within a certain time, for example, 3 minutes. The insulating tape prepared by the heat-sensitive material can insulate the bare wire and change color when the wire reaches a certain temperature, thereby playing a safety warning role.

[0031] In order to facilitate the quick cutting of the insulating tape 10, a cutter is designed to facilitate the use of the insulating tape 10. The plastic ring body 11 of the insulating tape 10 is sleeved on the cutter, and the insulating tape 10 is cut by the cutting blade 41.

[0032] The cutter comprises a supporting ring body 20, a supporting rod 21, a fixed plate 30 and a mounting block 40.

[0033] The supporting rod 21 is located in the supporting ring body 20, and the supporting rod 21 and the supporting ring body 20 are fixedly connected through a connecting rod 22. The fixed plate 30 is fixedly connected to the left side of the supporting rod 21 through a bolt, and a mounting groove 31 is formed in the fixed plate 30. A rotating rod 32 is rotatably connected in the mounting groove 31. A sliding block 33 is sleeved on the rotating rod 32. A sliding groove 35 is formed in the right end surface of the fixed plate 30, and the sliding block 33 is slidingly connected in the sliding groove 35. The mounting block 40 is fixedly connected to the right side of the sliding block 33, and is arranged as a square block with a hollow inside and a reserved slot in the bottom end surface. A cutting blade 41 is fixedly connected in the mounting block 40 through a mounting shaft, and the cutting end of the cutting blade 41 protrudes 1.5-2 cm from the bottom end surface of the mounting block 40.

[0034] The upper side of the rotating rod 32 penetrates through the upper end surface of the fixed plate 30 and extends to the outside of the fixed plate 30. A knob 34 is fixedly connected to the upper end of the rotating rod 32 for rotating the rotating rod 32. The rotating rod 32 is selected as a threaded rod, and a threaded through hole is formed in the sliding block 33. The rotating rod 32 is rotatably connected with the sliding block 33 through the threads.

[0035] The knob 34 is rotated forward or backward to rotate the rotating rod 32, so as to move the slider 33 up and down, thereby adjusting the height of the cutting blade 41, and facilitating the cutting of the insulation tape 10.

[0036] The cutting blade 41 is sleeved with a protective shell 50, which can protect the cutting blade 41 when not in use. The protective shell 50 is in the shape of a Chinese character "N" and has a reserved slot for inserting the cutting blade 41. Mounting holes 51 are formed on the front and rear end faces of the protective shell 50.

[0037] Limiting blocks 43 are fixedly connected to the inner walls of the left and right sides of the mounting block 40. Two limiting blocks 43 are arranged on each side. When the protective shell 50 is sleeved on the mounting block 40, the limiting blocks 43 limit the protective shell 50. Mounting holes 52 are formed on the front and rear end faces of the mounting block 40, and limiting bolts 42 are arranged in the mounting holes 52.

[0038] The protective shell 50 is sleeved on the outside of the cutting blade 41. The upper side of the protective shell 50 is inserted into the mounting block 40 and limited by the limiting blocks 43. When the protective shell 50 stops moving upward, the centers of the mounting holes 51 and the mounting holes 52 are on the same axis. The limiting bolts 42 are inserted into the mounting holes 51, and the protective shell 50 is fixed.

[0039] A return spring is further sleeved on the limiting bolt 42. The return spring is fixedly connected to the outer wall of the mounting block 40 and the nut of the limiting bolt 42. The return spring can provide power for the return of the limiting bolt 42, and can also prevent the limiting bolt 42 from falling off the mounting block 40.

[0040] The constituent components of the cutter are made of metal except the cutting blade 41 and the return spring, and the other components can be made of hard plastic.

[0041] It should be noted that the plastic ring body 11 on the insulation tape 10 has different sizes, which facilitates the use of the cutter. The support ring body 20 can be made into different sizes according to the size of the plastic ring body 11 on the insulation tape 10, so as to improve the practicability.

[0042] In actual operation, the plastic ring body 11 on the insulation tape 10 is sleeved on the outside of the support ring body 20 (a suitable size is selected. When the plastic ring body 11 is sleeved on the support ring body 20, the plastic ring body 11 is prevented from falling off but can rotate slowly). When the insulation tape 10 needs to be cut, the protective shell 50 is removed, the cutting blade 41 is exposed, and then the insulation tape 10 is cut. As the number of turns of the insulation tape 10 is reduced, the rotating rod 32 is rotated forward or backward by the knob 34, so as to move the slider 33 up and down, thereby adjusting the height of the cutting blade 41, and facilitating the cutting of the insulation tape 10.

[0043] The technical solutions in the embodiments of the application have at least the following technical effects or advantages: through the matching use of the cutter and the insulating tape, the insulating tape can be quickly and accurately cut, and the work efficiency is improved; and the protective shell and the limiting bolt can effectively protect the cutting blade when the cutting blade is not used; the height of the cutting blade is adjustable, the insulating tape of different turns can be adapted, and the operation convenience is further improved.

[0044] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
