[0038] By arranging a lower sealing box 5 and an upper sealing box 6 on the front side of the heating film body 1, and arranging an elastic supporting structure between the lower sealing box 5 and the upper sealing box 6, the wires 3 are reserved and supported. When the exposed wires 3 are subjected to external force, the reserved wires 3 will be moved out to buffer the external force, and then they will be stored again and restored to their original state, so that they can be reused many times.

[0039] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, a fastening structure is symmetrically provided on the left and right sides of the lower sealed box 5 and the upper sealed box 6, and the fastening structure includes a first movable groove 12, a second movable groove 13, a movable clamping block 14 and a positioning rod 15.

[0040] In the embodiment of the present invention, when in use, the positioning rod 15 is rotated with the first movable groove 12 as the rotation point, and then buckled into the movable clamping block 14 at the top of the second movable groove 13;

[0041] By setting up the fastening structure, the lower sealing box 5 and the upper sealing box 6 can be connected quickly and conveniently during use to form a whole, thereby protecting the internal structure and facilitating disassembly for inspection and placement of the internal structure.

[0042] like Figure 2 、 Figure 3 and Figure 5As shown, as a preferred embodiment of the present utility model, the elastic support structure includes a positioning plate 7, a guide rod 8, a slider 9, a spring 11 and a traction column 10.

The traction column 10 is symmetrically inserted into the inner side of the slider 9, and the rear end of the wire 3 is wrapped around the surface of the traction column 10 on the left and right sides.

[0043] In the embodiment of the present invention, when the exposed wires 3 are subjected to force, the wires 3 inside them will exert pressure on the traction columns 10 on the left and right sides, which in turn drives the sliders 9 at the bottom thereof to overcome the elasticity of the springs 11 and slide along the guide rods 8, thereby moving the reserved wires 3 out;

[0044] By providing an elastic support, it is possible to avoid the situation where the connection between the heating film body 1 and the wire 3 is damaged due to tripping over the exposed wire 3 .

[0045] like Figure 2 and Figure 5 As shown, as a preferred embodiment of the present invention, the width of the positioning plate 7 is equal to the width of the inner side of the lower sealing box 5 and the upper sealing box 6, and the height of the positioning plate 7 is equal to the height of the inner side of the lower sealing box 5 and the upper sealing box 6.

[0046] In an embodiment of the present invention, when in use, the placement of the positioning plate 7 is facilitated by making the width value of the positioning plate 7 equal to the width value of the inner side of the lower sealing box 5 and the upper sealing box 6, and the height value of the positioning plate 7 equal to the height value of the inner side of the lower sealing box 5 and the upper sealing box 6.

[0047] like Figure 2 and Figure 5 As shown in FIG. 1 , as a preferred embodiment of the present invention, the left and right traction posts 10 are staggered and symmetrically arranged, and the rear end of the wire 3 is wound around the surface of the traction post 10 in an S shape.

[0048] In the embodiment of the present invention, when in use, the left and right traction posts 10 are staggered and symmetrically arranged so that the rear end of the electric wire 3 is wound around the surface of the traction post 10 in an S shape.

[0049] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, the height value of the positioning rod 15 is equal to the sum of the side height values of the first movable groove 12 and the second movable groove 13, and the shape and size of the positioning rod 15 are adapted to the shape and size of the first movable groove 12 and the second movable groove 13.

[0050] In an embodiment of the utility model, when in use, by making the height value of the positioning rod 15 equal to the sum of the side height values of the first movable groove 12 and the second movable groove 13, and the shape and size of the positioning rod 15 are adapted to the shape and size of the first movable groove 12 and the second movable groove 13, the connection relationship between the first movable groove 12 and the second movable groove 13 is made more stable and firm.

When in use, the positioning rod 15 is pulled out from the movable clamping block 14 and then pulled out from the first movable groove 12 and the second movable groove 13, thereby releasing the connection between the lower sealing box 5 and the upper sealing box 6.

[0054] Then, the wire 3 extending from the positioning block 2 is wound around the surfaces of the traction posts 10 on the left and right sides, and then centered in the middle of the front side of the lower sealing box 5 and the upper sealing box 6;

[0055] Then, the positioning rod 15 is closed, so that the lower sealing box 5 and the upper sealing box 6 form a whole, protecting the internal structure;

[0056] When someone trips over the exposed wires 3, pressure is applied to the traction columns 10 on the left and right sides, which in turn drives the sliders 9 at the bottom thereof to overcome the elasticity of the springs 11 and slide along the guide rods 8, thereby moving the reserved wires 3 out, thereby avoiding damage to the connection between the heating membrane body 1 and the wires 3 due to tripping over the exposed wires 3;

[0057] When there is no force, the springs 11 act to move the traction posts 10 on both sides, thereby returning the reserved wires 3 to the lower sealing box 5 and the upper sealing box 6 and restoring the original state.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
