Description

Technical Field

[0001] This utility model relates to the field of electronic anode technology, specifically to an electronic anode for water heaters. Background Technology

[0002] Electric water heater tanks are prone to corrosion and perforation when submerged in water for extended periods. To prevent premature service life, an electronic anode is usually installed inside, which utilizes the magnesium rod in the center to preferentially corrode and reduce corrosion of the water heater tank.

[0003] In existing technologies, the current electronic anodes are usually installed directly using a threaded structure, which can easily lead to loosening over time. Utility Model Content

[0004] The purpose of this invention is to provide an electronic anode for water heaters, which solves the problem that existing electronic anodes in the above-mentioned background art are usually installed directly using a threaded structure, which leads to loosening over a long period of time.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an electronic anode for a water heater, including a mounting screw head, wherein an anti-detachment component is provided on the inner side of the mounting screw head, and the anti-detachment component is used to prevent detachment and improve sealing performance; and a locking component is provided on the outer side of the mounting screw head, and the locking component is used to prevent the mounting screw head from loosening when rotated.

[0006] The anti-detachment component includes a threaded sleeve, which is located on the back of the mounting screw head. The threaded sleeve is provided with a polytetrafluoroethylene (PTFE) threaded sleeve inside, and a sealing stud is provided on the inner side of the PTFE threaded sleeve. The front side of the PTFE threaded sleeve is filled with epoxy resin.

[0007] The locking assembly includes a fixing ring, and a rotating ring is embedded in the inner side of the fixing ring. Fixing blocks are installed on the front of both ends of the rotating ring, and threaded pins are provided on the inner side of the fixing blocks. Several sets of positioning holes are opened on the outer side of the mounting screw head.

[0008] Preferably, a magnesium rod is disposed inside the sealing stud, and a threaded post is installed on the front side of the sealing stud.

[0009] Preferably, a locking screw head is provided on the outer side of the threaded post, and the threaded post is located on the inner side of the epoxy resin adhesive.

[0010] Preferably, the top and bottom of the fixing ring are fitted with limit rings, and the inner side of the limit ring is provided with mounting bolts.

[0011] Preferably, two sets of fastening knobs are embedded on the front of the rotating ring, and the screw heads on the back of the fastening knobs contact the front of the fixing ring.

[0012] Preferably, the threaded pin is movably disposed inside the positioning hole.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this utility model has an anti-loosening component installed. The threaded sleeve can provide an installation position for the internal structure. The PTFE threaded sleeve can be used to cooperate with the sealing stud structure. When the threaded structure is connected to the PTFE threaded sleeve, the thread and the PTFE material generate an axial preload, which forces the contact surface of the connecting parts to press together, thereby increasing the tightness of the connection. Then, by filling with epoxy resin, the installation stability and sealing performance can be further maintained.

[0015] Secondly, this utility model incorporates a locking component. Existing electronic anode installations use bolts, but the bolt head lacks a locking mechanism, leading to potential liquid leakage and safety hazards if loosening occurs. The installation of a fixing ring restricts the rotation of the fitted ring. As the rotating ring rotates, it causes the fixing block to rotate synchronously. Finally, after locking with a tightening knob, a threaded pin is inserted into the corresponding positioning hole. This method further enhances the stability after installation, preventing loosening that could lead to liquid leakage and safety accidents. Attached Figure Description

A retaining block 402 is installed on the front of both ends of the rotating ring 4, and a threaded pin 403 is provided on the inner side of the retaining block 402. Several sets of positioning holes 101 are opened on the outer side of the mounting screw head 1.

[0025] Through the above technical solution, the threaded sleeve 102 can be used to provide an installation position for the internal structure, and the PTFE threaded sleeve 103 can be used to cooperate with the sealing stud 201 structure. When the threaded structure is connected to the PTFE threaded sleeve 103, the thread and the PTFE material generate an axial preload, which forces the contact surface of the connector to press together, thereby increasing the tightness of the connection. Then, by filling with epoxy resin adhesive 104, the installation stability and sealing performance can be further maintained.

[0026] Through the above technical solution, the fixed ring 3 can be installed to restrict the fitted rotating ring 4. When the rotating ring 4 rotates, it will drive the fixed block 402 to rotate synchronously. Finally, after locking by the fastening knob 401, the threaded pin 403 can be inserted into the positioning hole 101. This method of restriction further increases the stability after installation, thereby preventing loosening that could lead to liquid leakage and safety accidents.

[0027] Specifically, a magnesium rod 2 is provided inside the sealing stud 201, and a threaded post 202 is installed on the front side of the sealing stud 201.

[0028] Through the above technical solution, the magnesium rod 2 can react inside the water heater, reducing the wear of the inner tank through a sacrificial reaction, while the threaded column 202 is used to connect with the external structure to facilitate the electrical reaction.

[0029] Specifically, a locking screw head 203 is provided on the outer side of the threaded post 202, and the threaded post 202 is located on the inner side of the epoxy resin adhesive 104.

[0030] Through the above technical solution, the locking screw head 203 is used to assist in wiring installation.

[0031] Specifically, limiting rings 301 are installed at the top and bottom of the fixing ring 3, and mounting bolts 302 are provided on the inner side of the limiting rings 301.

[0032] Using the above technical solution, the retaining ring 301, together with the mounting bolt 302, can install the fixing ring 3 on the water heater.

[0033] Specifically, two sets of fastening knobs 401 are embedded in the front of the rotating ring 4, and the screw heads on the back of the fastening knobs 401 contact the front of the fixing ring 3.

[0034] Through the above technical solution, the fastening knob 401 can control the screw on the back to squeeze the fixing ring 3 by rotation, thereby using friction to achieve the locking effect.

[0035] Specifically, the threaded pin 403 is movably positioned inside the positioning hole 101.

[0036] In use, firstly, the threaded sleeve 102 is rotated and installed inside the mounting hole of the water heater by controlling the installation screw head 1 through the workpiece. Then, the fixing ring 3 is fixed by the installation bolt 302. Next, the threaded pin 403 is aligned with the inside of the positioning hole 101 by adjusting the rotating ring 4. After maintaining the alignment, the tightening knob 401 is tightened by using a tool. Finally, the threaded pin 403 is inserted into the inside of the positioning hole 101 to restrict the installation screw head 1.
