Abstract
Description
Technical Field
[0001] This utility model relates to a rotating shaft structure, and more particularly to a rotating shaft structure applied to the electrical control box of a wall-hung boiler. Background Technology
[0002] As is well known, the electrical control box of a wall-hung boiler is an important component of its control system. Its main function is to receive and output control signals, controlling the operation of the igniter, solenoid valves, and proportional valves to achieve constant heating and hot water temperatures. The control box typically includes a main control board and a control panel. The main control board processes signals from various sensors and regulates the gas and water flow through solenoid valves and proportional valves, thereby controlling the boiler's operation. The wall-hung boiler electrical control box generally consists of the following parts: Main control board: responsible for receiving and outputting control signals, controlling the operation of the igniter, solenoid valves, and proportional valves to achieve constant heating and hot water temperatures; Circuit board: The circuit board is divided into low-voltage and high-voltage areas, separated by a partition to avoid signal interference and ensure safety during maintenance.
[0003] As mentioned above, the electrical control box is an essential component of a wall-hung boiler. Because the electrical control box contains a large number of circuit boards, electrical components, and other structures, it is also a component that is prone to failure during the use of the wall-hung boiler. Once a failure occurs, the electrical control box needs to be repaired and maintained. However, traditional electrical control boxes are fixed to the wall-hung boiler with screws and other fasteners, which makes the operation very inconvenient during repair and maintenance. This is the main drawback of the existing technology. Utility Model Content
[0004] The technical solution adopted by this utility model is: a rotating shaft structure for a wall-hung boiler control box, the rotating shaft structure including a box body rotating shaft and a fixed bushing, wherein the box body rotating shaft is fixedly mounted on the control box, the fixed bushing is mounted on the bottom plate of the wall-hung boiler, and the box body rotating shaft is rotatably inserted into the fixed bushing.
[0005] The rotating shaft of the box is located on both sides of the bottom of the electrical control box. The rotating shaft includes an outer protrusion and a rotating shaft. The outer protrusion protrudes from the electrical control box and has an outer end face. The rotating shaft is fixedly connected to the outer end face.
[0006] The fixed bushing is disposed on the base plate corresponding to the rotating shaft of the box body. The fixed bushing includes a fixed plate, a sleeve body, and a support plate. The sleeve body and the support plate are respectively fixedly connected to the two ends of the fixed plate. The fixed plate has several assembly holes, and the assembly bolts are screwed into the assembly holes and the base plate to fix the fixed bushing on the base plate. The sleeve body corresponds to the rotating shaft of the box body, and the rotating shaft is rotatably inserted into the sleeve body. The support plate corresponds to the bottom surface of the electrical control box, and the outer protrusion of the rotating shaft of the box body is fixedly disposed on the bottom surface of the electrical control box.
[0007] The beneficial effects of this utility model are as follows: The design concept of this utility model is that by designing the above-mentioned box body rotating shaft and fixed bushing structure, the electrical control box can be flipped relative to the bottom plate of the wall-hung boiler. When the wall-hung boiler is in working state, the electrical control box stands upright on the bottom plate. At this time, the electrical control box is located in the wall-hung boiler. When the wall-hung boiler is in maintenance or repair state, the electrical control box can be flipped relative to the bottom plate by means of the box body rotating shaft and fixed bushing structure. After the flip is completed, the electrical control box is flipped to the outside of the wall-hung boiler, thereby facilitating the staff to open the electrical control box and repair or maintain its internal components.

[0014] like Figures 1 to 6 As shown, a rotating shaft structure for a wall-hung boiler control box includes a box body rotating shaft 100 and a fixed bushing 200. The box body rotating shaft 100 is fixedly mounted on the control box 10, and the fixed bushing 200 is mounted on the base plate 30 of the wall-hung boiler 20. The box body rotating shaft 100 is rotatably inserted into the fixed bushing 200.
[0015] like Figure 2As shown, the design concept of this utility model is to enable the electrical control box 10 to be flipped relative to the base plate 30 of the wall-hung boiler 20 by designing the above-mentioned box body rotating shaft 100 and fixed bushing 200. When the wall-hung boiler 20 is in working state, the electrical control box 10 is upright on the base plate 30. At this time, the electrical control box 10 is located in the wall-hung boiler 20. When the wall-hung boiler 20 is in maintenance or repair state, the electrical control box 10 can be flipped relative to the base plate 30 by means of the box body rotating shaft 100 and fixed bushing 200. After the flip is completed, the electrical control box 10 is flipped to the outside of the wall-hung boiler 20, thereby facilitating the staff to open the electrical control box 10 and perform maintenance or repair on its internal components.
[0016] The housing pivot 100 is disposed on both sides of the bottom of the electrical control box 10. The housing pivot 100 includes an outer protrusion 110 and a pivot 120. The outer protrusion 110 protrudes from the electrical control box 10 and has an outer end face 111. The pivot 120 is fixedly connected to the outer end face 111.
