Description
Technical Field
[0001] The utility model relates to the technical field of electric heating equipment, in particular to a heating pipe installation structure and a heating component. Background Art
[0002] The heating pipe structure is often used in electric heating tea tables, electric heaters and other equipment. For example, the inner sides of the four columns of the electric heating tea table and the five-sided heating stove are all equipped with a heating pipe structure.
[0003] When assembling the heating tube structure, it is necessary to fix both ends of the heating tube on the bracket, and to set electrodes at both ends of the heating tube to facilitate the connection of the wire. At present, the commonly used structure is to make the two ends of the heating tube pass through the bracket, and then set the electrode hoop at the end of the heating tube, and the electrode hoop is used to connect the wire. Under the above-mentioned penetration structure, the fixation of the two ends of the heating tube depends on the friction of the bracket. Under vibration, the heating tube is prone to axial movement or rotation, thereby driving the electrode hoop to move, and there is a risk of leakage caused by the electrode hoop touching the bracket, so the reliability is insufficient. In this regard, additional structures are also used on the market to fix the two ends of the heating tube, such as using a ceramic ring sleeved on the end of the heating tube, and the ceramic ring is fixed on the bracket. Although the contact area of the end of the heating tube is increased, the fixation of the two ends of the heating tube still depends on friction, and the problem of axial movement or rotation of the heating tube cannot be fundamentally solved; at the same time, the ceramic ring covers part of the heating area, which is easy to cause heat accumulation near the end of the heating tube, resulting in burning near the electrode hoop, resulting in a high failure rate and a short service life. Utility Model Content
[0004] The technical problem to be solved by the utility model is: how to improve the reliability of fixing the two ends of the heating tube and avoid heat accumulation near the ends of the heating tube.

During operation, the wire is inserted into the wiring hole 5 and connected to the open side of the electrode hoop 4, and the heating column 1 can be powered on. One side of the electrode hoop 4 is inserted into the wiring shell 3, and the wiring shell 3 can limit the electrode hoop 4 circumferentially. When the heating column 1 rotates, the electrode hoop 4 will not rotate with the heating column 1, so that the problem of the electrode hoop 4 pulling the wire and causing the wire to burn will not occur, and the risk of leakage caused by the electrode hoop 4 or the wire touching the bracket is avoided.
[0039] By adopting the utility model, the two ends of the heating column 1 are limited by the tube sleeve 2, so that the axial movement of the heating column 1 is avoided, and the reliability is good; when the heating column 1 is subjected to circumferential force, the terminal shell 3 can circumferentially limit the electrode hoop 4 to prevent the rotation of the electrode hoop 4, thereby avoiding the risk of leakage; at the same time, the two ends of the heating column 1 do not need to rely on friction for fixation, so the two ends of the heating column 1 only need to extend from the electrode part into the tube sleeve 2, thereby avoiding the problem of heat accumulation caused by excessive coverage of the heating column 1, reducing the failure rate and increasing the service life.

[0049] Note: The electrode hoop 4 can be made of a patch bent into a circle, and its open side extends into the wiring shell 3 and is used for wiring. When wiring, the electrode hoop 4 is deformed by winding the wire around the open side, so that the two ends of the heating column 1 can be tightly embraced, and the contact reliability is good.
