Detailed Implementation

[0025] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0026] This application discloses an electric heating belt that is easy to assemble and disassemble.

[0027] An easy-to-assemble and disassemble electric heating belt, see reference Figure 1-4 The device includes an electric heating belt body 1 and a fixing mechanism. The electric heating belt body 1 includes an outer layer cloth 11, an inner layer cloth 12, an insulation layer 13 fixed between the outer layer cloth 11 and the inner layer cloth 12, and a heating wire 14 fixed between the inner layer cloth 12 and the insulation layer 13. The outer layer cloth 11 and the inner layer cloth 12 can be carbon coated fiber cloth, which has corrosion resistance, certain waterproof and insulation effects. The insulation layer 13 can be a high silica needle-punched pad, which has heat preservation effects. The heating wire 14 can be a nickel-chromium alloy wire heating wire, which can heat the inside of the electric heating belt body 1. The outer layer cloth 11, the inner layer cloth 12 and the insulation layer 13 can be connected by sewing thread.

[0028] Reference Figure 1-2 An AMP quick connector 4 is fixedly provided on the outer layer 11 of the electric heating belt body 1, and the electric heating belt body 1 can be quickly connected to an external circuit through the AMP quick connector 4.

[0029] Reference Figure 1-2 A PID controller 5 is fixedly installed in the middle of the outer layer 11 of the electric heating belt body 1. A strap 51 is fixedly installed in the outer layer 11 of the electric heating belt body 1. The PID controller 5 is fitted into the inside of the strap 51. The operator can control the temperature of the electric heating belt body 1 through the PID controller 5. The strap 51 can cover the PID controller 5, thereby fixing the PID controller 5 and preventing the position of the PID controller 5 from moving. The AMP quick connector 4 and the PID controller 5 are common components of existing electric heating belts. Their circuit connection and principle have been disclosed and will not be described in detail here.

[0030] Reference Figure 1-2 A temperature-sensitive color-changing label 6 is fixedly provided on the outer layer 11 of the electric heating belt body 1. When the electric heating belt body 1 is de-energized, the staff can judge the residual temperature on the surface of the electric heating belt by observing the color of the temperature-sensitive color-changing label 6. This makes it less likely for the staff to touch the electric heating belt that still has a high temperature after the power is off and get burned, thus improving the safety of the electric heating belt.

[0031] Reference Figure 1-3 The fixing mechanism is located on both sides of the electric heating belt body 1. The fixing mechanism is used to fix the electric heating belt body 1 tightly wrapped around the outside of pipes and other items. The fixing mechanism includes a hook and loop fastener 2 fixed on one edge of the electric heating belt body 1, a number of connecting straps 21 fixed on the other edge of the electric heating belt body 1, and a hook and loop fastener hook surface 22 fixed on one side of the connecting strap 21 for fixing the electric heating belt body 1 by adhering the hook and loop fastener 2. The connecting strap 21 can connect the hook and loop fastener hook surface 22 to the electric heating belt body 1.

[0032] The electric heating belt 1 is quickly installed and fixed by wrapping and tightly wrapping it around the outside of pipes and other items, and by using the hook and loop fastener 22 to attach the loop fastener 2. By attaching the hook and loop fastener 22 to different positions on the loop fastener 2, the electric heating belt 1 can be installed on the outside of items of different sizes. The installation and removal of the electric heating belt 1 can be completed simply by attaching or tearing the hook and loop fastener 22, which is simpler and more convenient.

[0033] Reference Figure 1-2 A connecting rod 23 is fixedly provided between several connecting straps 21. The connecting rod 23 can connect several connecting straps 21, thereby connecting several hook and loop fasteners 22 on several connecting straps 21, making it convenient and quick for workers to tear the hook and loop fasteners 22 off the hook and loop fasteners 2 as a whole from the hook and loop fasteners 2.

[0034] Reference Figure 1-2 The electric heating belt body 1 has several sponge blocks 3 for anti-slip on the side near pipes and other items. Several fixing holes 15 are opened in the inner layer cloth 12. A waterproof cloth 31 is fixed in the fixing holes 15 of the inner layer cloth 12. The sponge blocks 3 are fixed in the waterproof cloth 31. One end of the sponge block 3 protrudes from the inner layer cloth 12 of the electric heating belt body 1. The waterproof cloth 31 can connect the sponge block 3 and the inner layer cloth 12. When the sponge block 3 absorbs water, it is not easy to transfer water to the interior of the electric heating belt body 1, such as the insulation layer 13.

[0035] The sponge block 3 protruding from the inner side of the electric heating belt body 1 can prevent the electric heating belt from slipping after installation, making it less likely to slide down when installed on vertically arranged pipes or other items. When the electric heating belt body 1 is installed, it will be tightly attached to the pipes or other items, thereby compressing the protruding sponge block 3 into the fixing hole 15 of the inner layer cloth 12. This allows the protruding sponge block 3 to shrink and deform and be pressed into the fixing hole 15, so that the inner layer cloth 12 of the electric heating belt body 1 can be tightly attached to the outside of the pipes or other items, thus ensuring that the electric heating belt can properly heat the pipes or other items.

[0036] The implementation principle of the easily detachable electric heating belt in this application embodiment is as follows:

[0037] When in use, first lay the electric heating belt body 1 flat and arrange it, then wrap the electric heating belt body 1 tightly around the outside of pipes and other items. At this time, the protruding sponge block 3 will be compressed and deformed into the fixing hole 15 of the inner layer cloth 12, so that the inner layer cloth 12 of the electric heating belt body 1 can be tightly attached to the outside of pipes and other items.

[0038] Then the staff can hold the connecting rod 23 and, with the connection of several connecting straps 21, stick several hook and loop fasteners 22 onto the hook and loop fasteners 2 to install and fix the electric heating belt body 1. The sponge block 3 can prevent the electric heating belt from slipping after installation, so that the electric heating belt will not slip when installed on vertical pipes or other items.

[0039] Then, the staff can quickly connect the electric heating belt 1 to the external line through the AMP quick connector 4, and then control the temperature of the electric heating belt 1 through the PID controller 5. When the electric heating belt 1 is running, it can heat the pipes and other items.

[0040] After heating is complete, staff can judge the residual temperature on the surface of the electric heating belt by observing the color of the temperature-sensitive color-changing label 6. When the surface temperature of the electric heating belt body 1 cools down, staff can hold the connecting rod 23 and quickly tear the hook side 22 off the hook side 2 to disassemble the electric heating belt body 1.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
