Description

Technical Field

[0001] The invention discloses a stopper structure for installing an electric heating pipe, which is a structure and a method for installing an electric heating pipe on an electric heating appliance, and belongs to the field of electric heating appliances. Background Art

[0002] Generally, the electric heating tube of an electric heating device is installed on the two walls of the electric heating device. Steps are arranged at the two ends of the electric heating tube. One side of the two walls is a mounting hole. The diameter of the mounting hole matches the outer diameter of the head of the electric heating tube. The mounting hole can block the step of the electric heating tube. The other side of the two walls is a through hole. The diameter of the through hole is larger than the diameter of the step of the electric heating tube. The electric heating tube can pass through the through hole and then the step of the electric heating tube is blocked by a retaining spring or the like to achieve installation. The use of retaining springs for installation has the disadvantages of being troublesome to install, easy to scale, and unsightly. Summary of the invention

[0003] The present invention provides an electric heating pipe stopper structure for installing the electric heating pipe. A mounting hole is arranged on one side of two walls of the electric heater. The diameter of the mounting hole matches the outer diameter of the head of the electric heating pipe. When the electric heating pipe is installed, a step at one end of the electric heating pipe can be blocked. A through hole is arranged on the other side of the two walls. A stopper for blocking the electric heating pipe is arranged above the through hole. A cutting slit is arranged above the stopper so that the stopper can be bent outward to clear the step of the electric heating pipe and allow the electric heating pipe to pass through. After the electric heating pipe is installed in place, the stopper is bent back and reset to block the step of the electric heating pipe and install the electric heating pipe.

[0004] In order to block the gap left at the through hole after the electric heating pipe is installed, a fitting head is provided at the lower part of the stopper, the upper part of the fitting head matches the diameter of the through hole, and the lower part matches the outer diameter of the electric heating pipe. After the stopper is bent back and reset, the fitting head can block the step of the electric heating pipe and the gap left at the through hole.

[0005] The present invention is completed by the following scheme. The stopper structure for installing the electric heating pipe of the present invention is composed of a through hole 1, a stopper 2, a stopper seam 3, a matching head 4, a mounting hole 5, two walls 6, an outer diameter of the electric heating pipe 7, and an electric heating pipe step 8. The mounting hole 5 is set on one side of the two walls 6 of the electric heater. The diameter of the mounting hole 5 matches the outer diameter 7 of the electric heating pipe at the head of the electric heating pipe. The mounting hole 5 can block the electric heating pipe step 8. The other side of the two walls 6 is set as a through hole 1, and the electric heating pipe can pass through. It is characterized in that a stopper 2 is provided above the through hole 1, and the stopper 2 is used to block the electric heating pipe step 8. A stopper seam 3 is cut above the stopper 2, so that the stopper 2 can be bent outward to make way for the electric heating pipe step 8 and allow the electric heating pipe to pass through. After the electric heating pipe is installed in place, the stopper 2 is bent back and reset to block the electric heating pipe step 8 to achieve the installation of the electric heating pipe.

[0006] The lower part of the stop head 2 of the stop head structure for installing the electric heating pipe is provided with a fitting head 4, the upper part of the fitting head 4 matches the diameter of the through hole 1, and the lower part matches the outer diameter 7 of the electric heating pipe. After the stop head 2 is bent back and reset, the fitting head 4 blocks the step 8 of the electric heating pipe and the gap left at the through hole 1.

[0007] The following is a description with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The stopper structure for installing the electric heating pipe of the present invention is composed of a through hole 1, a stopper 2, a stopper seam 3, an anastomosis head 4, a mounting hole 5, two walls 6, an outer diameter of the electric heating pipe 7, and an electric heating pipe step 8. The mounting hole 5 is set on one side of the two walls 6 of the electric heater. The diameter of the mounting hole 5 matches the outer diameter 7 of the electric heating pipe at the head of the electric heating pipe. The mounting hole 5 can block the electric heating pipe step 8. The other side of the two walls 6 is set as a through hole 1, and the electric heating pipe can pass through. A stopper 2 is provided above the through hole 1. The stopper 2 is used to block the electric heating pipe step 8. A stopper seam 3 is cut above the stopper 2 so that the stopper 2 can be bent outward. When the bend is close to 90 degrees, the electric heating pipe step 8 can be made to pass through. After the electric heating pipe is installed in place, the stopper 2 is bent back and reset to block the electric heating pipe step 8 to achieve the installation of the electric heating pipe.

[0015] In order to block the gap left at the through hole 1 after the electric heating pipe is installed, a fitting head 4 is provided at the lower part of the stop head 2. The upper part of the fitting head 4 matches the diameter of the through hole 1, and the lower part matches the outer diameter 7 of the electric heating pipe. When installing the electric heating pipe, the stop head 2 is bent outward nearly 90 degrees, and the fitting head 4 can be used to make way for the electric heating pipe step 8 to allow the electric heating pipe to pass through. After the electric heating pipe is installed in place, the stop head 2 is bent back and reset to block the electric heating pipe step 8 to achieve the installation of the electric heating pipe and block the gap left at the through hole 1.
