Description

Technical Field

[0001] This utility model belongs to the field of heating tube technology, specifically a flange water heater heating tube structure with integrated thermostat. Background Technology

[0002] The integrated thermostat flange water heater heating tube structure is a highly efficient and safe heating device. It mainly consists of a heating tube, a temperature sensing tube, a flange, a control box, and lead wires. The heating tube is the core component, responsible for generating heat; the temperature sensing tube monitors the temperature of the heating medium in real time; the flange secures the heating tube to the equipment and ensures good contact between the heating tube and the medium; the control box integrates a thermostat, which adjusts the heating tube's power based on the temperature feedback from the temperature sensing tube, achieving precise temperature control; and the lead wires connect the power supply to the control box. This integrated thermostat flange water heater heating tube structure is widely used in various applications requiring liquid heating, such as water heaters, boilers, and chemical equipment. Its high efficiency, safety, and reliability enable these devices to maintain stable temperatures during heating, improving heating efficiency and service life. However, existing flange water heater heating tubes lack effective protection for the flange bolt caps, allowing moisture in the air to easily penetrate the flange holes and corrode the bolts, leading to stripped threads. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a flange water heater heating tube structure with integrated thermostat, which effectively solves the problem that the flange bolt cap of the existing flange water heater heating tube is not effectively protected, which makes it easy for moisture in the air to penetrate into the flange hole and corrode the bolt, resulting in stripped bolt threads.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flange water heater heating tube structure with an integrated thermostat, comprising a flange, five heating tubes fixedly installed at equal intervals in a ring on one side of the flange, a temperature measuring tube fixedly installed in the middle of one side of the flange, a plurality of flange connection holes equally spaced in a ring on the surface of the flange, flange bolts inserted into the interior of each flange connection hole, bolt caps fixedly installed at one end of each flange bolt, a protective cover corresponding to the plurality of bolt caps provided on the other side of the flange, a control box fixedly installed in the middle of the other side of the flange, a limit hole provided in the middle of one side of the control box, a fixed pull ring provided on the side of the control box away from the flange, a transmission component provided on the surface of the fixed pull ring, the transmission component being connected to the plurality of protective covers, and when the fixed pull ring is adjusted, the transmission component can drive the plurality of protective covers to cover the surface of the plurality of bolt caps for protection.

[0005] Preferably, the transmission assembly includes a fixed pull rod, which is fixedly installed on the surface of a fixed pull ring. A rotating rod is fixedly installed at one end of the fixed pull rod, and a limit block is fixedly installed at one end of the rotating rod. The limit block engages with the inside of a limit hole.

[0006] Preferably, a rotating bushing is rotatably mounted on the surface of the rotating rod, and four connecting rods are fixedly mounted circumferentially at equal intervals on the surface of the rotating bushing. A limiting sleeve is fixedly mounted on the end of each of the four connecting rods away from the rotating bushing. A limiting rod is inserted into the inside of each limiting sleeve. One end of each limiting rod is fixedly connected to the other side of the flange through a fixed seat. A telescopic spring is sleeved on the surface of each of the four limiting rods, and both ends of the four telescopic springs are fixedly connected to the limiting sleeve and the limiting rod, respectively.

[0007] Preferably, a fixing sleeve is fixedly installed on the surface of the fixing rod, and a plurality of support bars are fixedly installed circumferentially at equal intervals on the surface of the fixing sleeve. A support rod is fixedly installed at one end of each of the support bars, and one end of each support rod is fixedly connected to a plurality of protective covers.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the operator inserts five heating tubes and temperature measuring tubes into the interior of the water heater body, then inserts several flange bolts into several flange connection holes on the flange plate, and then rotates several bolt caps with a wrench to fix the flange plate onto the water heater body to complete the installation; then the operator pulls the fixing pull rod and rotating rod through the fixing pull ring. When the fixing pull rod is pulled, it drives several support bars to move through the fixing sleeve. When the support bars move, they drive several protective covers to move through several support rods. When the rotating rod is pulled, it drives the limit block to exit the limit hole to release the limit, and drives four connecting rods to move through the rotating bushing. When the four connecting rods move, they all drive the limit sliding sleeve to slide along the surface of the four limit sliding rods, and at the same time compress the four telescopic springs.

[0009] The operator then rotates the fixed pull rod by using the fixed pull ring. As the fixed pull rod rotates, it causes the rotating rod to rotate along the inside of the rotating sleeve, and simultaneously rotates the limit block. The rotation of the rotating rod, through the fixed sleeve, causes several support bars to rotate. The rotation of these support bars, in turn, causes several protective covers to rotate through several support rods. The operator then releases the fixed pull ring, allowing the limit block to engage with the limit hole under the elastic force of four telescopic springs. This also causes several protective covers to cover several bolt heads for protection. This effectively protects the flange bolt heads from moisture in the air, preventing moisture from entering the flange connection hole and corroding the flange bolts, thus avoiding stripping of the flange bolt threads.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1 to 5The present invention includes a flange 1. Five heating tubes 2 are fixedly installed at equal intervals in a ring on one side of the flange 1. A temperature measuring tube 3 is fixedly installed in the middle of one side of the flange 1. A plurality of flange connection holes 4 are opened at equal intervals in a ring on the surface of the flange 1. Flange bolts 5 are inserted into the flange connection holes 4. A bolt cap 6 is fixedly installed at one end of each flange bolt 5. A protective cover 7 corresponding to the bolt caps 6 is provided on the other side of the flange 1. A control box 8 is fixedly installed in the middle of the other side of the flange 1. A thermostat is installed inside the control box 8. The cooperation between the thermostat and the temperature measuring tube 3 can effectively monitor and control the temperature of the heating tubes 2. A limit hole 9 is opened in the middle of one side of the control box 8. A fixing pull ring 10 is provided on the side of the control box 8 away from the flange 1. A transmission component is provided on the surface of the fixing pull ring 10. The transmission component is connected to the plurality of protective covers 7. When the fixing pull ring 10 is adjusted, the transmission component can drive the plurality of protective covers 7 to cover the surface of the plurality of bolt caps 6 for protection.

[0020] During installation, the operator inserts five heating elements 2 and a temperature measuring element 3 into the interior of the water heater body. Then, several flange bolts 5 are inserted into several flange connection holes 4 on the flange plate 1. Next, several bolt caps 6 are rotated using a wrench to fix the flange plate 1 onto the water heater body, completing the installation. Then, the operator adjusts the operation of the transmission component by fixing the pull ring 10. When the transmission component operates, it will drive several protective covers 7 to move. At the same time, the transmission component will also drive several protective covers 7 to rotate. Through the elasticity of the transmission component itself, several protective covers 7 will cover several bolt caps 6 for protection. This allows the heating elements of this flange water heater to effectively protect the flange bolt caps 6, preventing moisture in the air from entering the flange connection holes 4 and corroding the flange bolts 5, thus avoiding the phenomenon of stripping the flange bolts 5.

[0021] The transmission assembly includes a fixed pull rod 11, which is fixedly mounted on the surface of a fixed pull ring 10. A rotating rod 13 is fixedly mounted on one end of the fixed pull rod 11, and a limit block 15 is fixedly mounted on one end of the rotating rod 13. The limit block 15 engages with the inside of a limit hole 9. A rotating bushing 14 is rotatably mounted on the surface of the rotating rod 13. Four connecting rods 16 are fixedly mounted circumferentially at equal intervals on the surface of the rotating bushing 14. Limit sleeves 17 are fixedly mounted on the ends of the four connecting rods 16 away from the rotating bushing 14. Limit sleeves 17 are inserted into the inside of each limit sleeve 17. One end of each of the rods 19 and the limiting slide rods 19 is fixedly connected to the other side of the flange 1 via a fixed seat 18. Each of the four limiting slide rods 19 is fitted with a telescopic spring 20, and both ends of the four telescopic springs 20 are fixedly connected to the limiting slide sleeve 17 and the limiting slide rod 19, respectively. A fixed sleeve 12 is fixedly installed on the surface of the fixed pull rod 11. Several support bars 21 are fixedly installed in a ring at equal intervals on the surface of the fixed sleeve 12. A support rod 22 is fixedly installed at one end of each of the support bars 21. One end of each support rod 22 is fixedly connected to several protective covers 7.

[0022] The operator pulls the fixed pull rod 11 and the rotating rod 13 through the fixed pull ring 10. When the fixed pull rod 11 is pulled, it drives several support bars 21 to move through the fixed sleeve 12. When the support bars 21 move, they drive several protective covers 7 to move through several support rods 22. When the rotating rod 13 is pulled, it drives the limit block 15 to exit the limit hole 9 to release the limit, and drives the four connecting rods 16 to move through the rotating bushing 14. When the four connecting rods 16 move, they all drive the limit sliding sleeve 17 to slide along the surface of the four limit sliding rods 19, and at the same time squeeze the four telescopic springs 20.

[0023] Then, the operator drives the fixed pull rod 11 to rotate through the fixed pull ring 10. When the fixed pull rod 11 rotates, it drives the rotating rod 13 to rotate along the inside of the rotating bushing 14, and the rotating rod 13 drives the limit block 15 to rotate synchronously. When the rotating rod 13 rotates, it drives several support bars 21 to rotate through the fixed sleeve 12. When several support bars 21 rotate, they drive several protective covers 7 to rotate through several support rods 22. Then, the operator releases the fixed pull ring 10, so that under the elastic force of the four telescopic springs 20, the limit block 15 is driven into the inside of the limit hole 9 for limiting, and the several protective covers 7 cover several bolt caps 6 for protection.
