Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and more specifically, it relates to a mounting bracket for an electric heating tube. Background Technology

[0002] An electric heating element is an electrical component that converts electrical energy into heat energy. It is typically made of a metal tube (such as stainless steel or copper) with a spiral heating alloy wire evenly distributed along its central axis inside, and the gaps are filled with magnesium oxide powder, which has good insulation and thermal conductivity. Electric heating elements are typically sealed at both ends with silicone and can be used to heat air, metal molds, and various liquids. They are characterized by simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, and long service life. Due to their low price, ease of use, and lack of pollution, electric heating elements are widely used in various heating applications, such as nitrate tanks, water tanks, oil tanks, and acid / alkali tanks. Furthermore, they are widely used in the pharmaceutical, chemical, and food industries, favored for their high efficiency and energy-saving characteristics. The electric heating element mounting bracket is an important component of an electric heater, its main function being to fix and support the heating element. The bracket ensures that the heating element does not wobble or become unstable during operation, preventing it from falling off, thus guaranteeing the stability and safety of the heater. Water heaters are among the most commonly used electrical appliances in daily life, and the heating element is an extremely important component. However, scale easily accumulates on the heating element in water heaters, increasing its weight over time and making it prone to loosening or falling off. Moreover, the heating element in a water heater must have excellent insulation properties; otherwise, accidents can easily occur. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a mounting bracket for an electric heating element, which solves the issues of insufficient support capacity of the mounting bracket, excessive scale accumulation causing the heating element to loosen, and poor insulation and sealing performance.

[0004] This utility model discloses a mounting bracket for an electric heating element, achieved through the following specific technical means:

[0005] A mounting bracket for an electric heating element includes: a heating element; a connecting end cap connected to the rear end of the heating element, the connecting end cap consisting of two cylindrical gaskets, the cylindrical gasket closer to the heating element having a smaller diameter and the cylindrical gasket further away from the heating element having a larger diameter; a connecting piece provided on the rear side of the connecting end cap, the connecting piece having a connecting bolt; a mounting ring provided on the connecting end cap, a wrapping ring provided on the front side of the mounting ring, the wrapping ring fitting onto the larger diameter cylindrical gasket; a locking ring provided on the front side of the wrapping ring, the locking ring fitting onto the smaller diameter cylindrical gasket; eight sets of mounting threaded holes provided on the mounting ring, mounting bolts provided in the mounting threaded holes, and mounting nuts provided on the mounting bolts.

[0006] Furthermore, an insulating ring is provided at the connection between the threaded rod and the top cap of the mounting bolt.

[0007] Furthermore, an insulating ring is provided at one end of the outer side of the mounting nut, and the inner diameter of the insulating ring is smaller than the diameter of the hole in the mounting nut.

[0008] Furthermore, a small-diameter sealing ring is provided at the bend of the inner wall of the positioning ring.

[0009] Furthermore, a large-diameter sealing ring is provided at the turning point of the inner wall of the wrapping ring.

[0010] Furthermore, the mounting ring, wrapping ring, locking ring, mounting bolt, and mounting nut are all made of high-temperature and corrosion-resistant insulating materials.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting an insulating ring and a sealing ring, this utility model can not only effectively prevent water from entering the connecting piece from the water heater, thus achieving a sealing effect, but also prevent water from accidentally leaking onto the connecting piece, thus preventing the water in the water heater from being electrified and causing an accident, thus achieving an insulating effect.

[0013] 2. This utility model uses high-temperature and corrosion-resistant insulating materials for the mounting ring, wrapping ring, locking ring, mounting bolt, and mounting nut, which effectively prevents static electricity generated by metal friction and electrical conduction at the connection point of the connecting piece and the mounting bracket, thus providing insulation.

[0014] 3. This utility model is installed by setting six sets of mounting bolts, so even if the heating element has been used for a long time and has a lot of scale, the mounting bracket can still support it. Attached Figure Description
