Description

Technical Field

[0001] The utility model relates to the technical field of electric heating carpets, and more specifically, to a connection structure of an electric heating carpet. Background Art

[0002] Electric carpet, also known as electric mattress, is a contact electric heating device. Its working principle is to weave or sew special soft rope electric heating elements with standard insulation performance into the blanket in a snake shape, which emits heat when powered on.

[0003] When the weather is cold, the electric heating carpet can be laid flat on the ground to provide people with rest and warmth, and can also be used to remove moisture from bedding. It has the advantages of being easy to use and having a wide range of uses. Existing electric heating carpets are generally laid directly on the ground without any connecting structure, which makes the carpet easy to slide. When children or adults play or walk on the carpet, once the carpet slides, injuries may occur, which lacks safety, and therefore needs to be improved. Utility Model Content

[0024] When the operator needs to connect the shell 1 as a whole to the ground, he can rotate the rotating plate 9 to make the rotating plate 9 disengage from the fixed cylinder 2, thereby releasing the supporting effect on the round rod 4. Since the first spring 7 is in a stretched state, the first spring 7 can pull the movable plate 6 downward under the action of elastic recovery, so that the movable plate 6 drives the round rod 4 to move downward, and then the suction cup 5 can move downward. The operator can press the top plate 10 downward so that the suction cup 5 can be tightly connected to the ground, thereby ensuring the overall stability of the shell 1.

[0025] Among them, a slide groove 11 is opened on the upper surface of the shell 1, and a connecting block 12 located below the slide groove 11 is movably installed inside the shell 1. An installation box 13 is fixedly installed on the top of the connecting block 12, and the outer surface of the installation box 13 is movably connected to the inner surface of the slide groove 11.

[0026] By providing the sliding groove 11 , the connecting block 12 can drive the installation box 13 to move along the inner surface of the sliding groove 11 .

[0027] Among them, a lower splint 14 is fixedly installed on the inner side of the installation box 13, and the bottom of the lower splint 14 is movably connected to the upper surface of the shell 1. A lifting plate 15 is movably installed inside the installation box 13, and an upper splint 17 is fixedly installed on the left side of the lifting plate 15, and a pull plate 18 is fixedly installed on the right side of the lifting plate 15.

[0037] The working principle and use process of this utility model:

[0038] When the operator uses the electric heated carpet, he first rotates the rotating block 21 according to the size of the electric heated carpet, so that the threaded rod 20 drives the moving block 22 to move, and then the hinged rod 23 can drive the two connecting plates 19 to move, so that the connecting block 12 can drive the installation box 13 to move, so that the electric heated carpets of different sizes can be clamped and fixed. Then, the operator pulls the pull plate 18 upward, so that the lifting plate 15 drives the upper clamping plate 17 to move upward, and places a corner of the electric heated carpet on the upper surface of the lower clamping plate 14. Then, the operator releases the pull plate 18, so that the second spring 16 pulls the lifting plate 15 downward under the action of elastic recovery, so that the upper clamping plate 17 can move downward, and then the lower clamping plate 14 and the upper clamping plate 17 can clamp and fix the electric heated carpet.

[0039] The operator rotates the rotating plate 9 to make the rotating plate 9 break away from the contact with the fixed cylinder 2, thereby releasing the supporting effect on the round rod 4.
