Problems solved by technology
[0002] Generally, the electric heating tube of the electric heating appliance is installed on the two walls of the electric heating appliance. The two heads of the electric heating tube are provided with steps, and 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. For the steps of the electric heating tube, the other side of the two walls is a via hole. The diameter of the via hole is larger than the diameter of the electric heating tube step. The electric heating tube can pass through the via hole, and then block the steps of the electric heating tube with a circlip to achieve installation. Use a circlip to install , there are defects such as troublesome installation, easy scaling and unsightly appearance

The invention relates to a stopper structure for installing an electric heating tube and a method , and belongs to the field of electric heating appliances. The stopper structure is a structure for installing the electric heating tube on an electric heating appliance. One side of two walls of an electric heater is provided with amounting hole. The mounting hole can block a step at one end of the electric heating tube. A blocking head is arranged above a via hole formed in the other side of the two walls. And a cutting seam is formed above the blocking head, so that the blocking head can be bent outwards, and the electric heating tube can penetrate through the blocking head. After the electric heating tube is installed in place, the blocking head is bent back to reset, and the step on the other side of the electric heating tube can be blocked to achieve installation of the electric heating tube. The lower portion of the blocking head is provided with an anastomosis head, the upper portion of the anastomosis head is matched with the diameter of the via hole, the lower portion of the anastomosis head is matched with the outer diameter of the electric heating tube, and the anastomosis head can block the step of the electric heating tube and a gap left at the via hole after the blocking head is bent back and reset.
