Technical Field

[0001] The utility model relates to the technical field of installation of a heater control panel, in particular to a heater control panel which is easy to replace. Background Art

[0002] The wall-mounted structure of the heater control panel refers to the control panel structure installed on the wall. Its main function is to facilitate users to operate and control the heater, and at the same time, it is beautifully integrated into the interior decoration to enhance the comfort and aesthetics of the overall space. The control panel is usually equipped with various operating buttons, knobs or display screens to control the heater's switch, temperature adjustment, wind speed adjustment and other functions.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a heater control panel that is easy to replace, including a control panel body 1 and a circular back frame 2 for fitting with the control panel body 1, the circular back frame 2 is bolted and fixed to a square hole on the wall, square connecting columns 301 are fixed on the left and right outer walls of the circular back frame 2, right-angle shaft seats 7 are fixed on both sides of the back of the control panel body 1, through holes are opened at both ends of the surface of the right-angle shaft seat 7, and the right-angle shaft seat 7 is fixed to the back of the control panel body 1 through the through holes and screws;

[0021] A vertical shaft 8 is rotatably mounted on the outer wall of the opposite side of the two right-angle shaft seats 7. Both ends of the surface of the vertical shaft 8 are fixed with plug blocks 9 for interference-fitting with the square connecting column 301. A rotating drive structure 10 is installed on both sides of the back of the control panel body 1. The rotating drive structure 10 is used to drive the vertical shaft 8 to rotate. The rotating drive structure 10 can be manually screwed, and the rotating drive structure 10 drives the vertical shaft 8 to rotate. In this process, the right-angle shaft seat 7 supports the rotation of the vertical shaft 8. When the vertical shaft 8 and the plug block 9 rotate ninety degrees toward the direction of the square connecting column 301, the plug block 9 will enter the square connecting column 301. At this time, the plug block 9 and the square connecting column 301 maintain an interference-fitting state.

[0022] The corners of the circular back frame 2 are all integrally formed with arc-shaped side seats 3, and the interior of the arc-shaped side seats 3 is provided with internal thread positioning columns 4 that completely penetrate the arc-shaped side seats 3. The corners of the circular back frame 2 are all integrally formed with arc-shaped side seats 3. When the circular back frame 2 is placed in the square hole on the wall, the staff passes the bolts through the internal thread positioning columns 4 and screws them into the wall, thereby completing the fixing work of the circular back frame 2;

[0023] Rectangular inner grooves 6 are provided on both sides of the surface of the square connecting column 301. The rectangular inner grooves 6 and the plug-in blocks 9 are plugged in an interference fit. A shaft cylinder 701 is integrally formed on the outer wall of the right-angle shaft seat 7 close to the central reference surface of the control panel body 1. The vertical shaft 8 is rotatably installed inside the shaft cylinder 701. The outer diameter of the vertical shaft 8 is equal to the inner diameter of the shaft cylinder 701. When the vertical shaft 8 rotates, since the inner diameter of the shaft cylinder 701 is equal to the outer diameter of the vertical shaft 8, the vertical shaft 8 can maintain a stable rotation movement. Since the plug-in blocks 9 are installed at both ends of the vertical shaft 8, when the vertical shaft 8 rotates, the two plug-in blocks 9 can be synchronously embedded in the rectangular inner grooves 6.

[0024] The insert block 9 is made of a hard plastic material. The corners of the inner wall of the circular back frame 2 are all fixed with baffles 5. When the control panel body 1 enters the circular back frame 2, the baffles 5 will abut against the back of the control panel body 1. At this time, the control panel body 1 cannot be pushed forward, indicating that the control panel body 1 is installed in place.

[0025] The rotary drive structure 10 includes a worm 1003 rotatably mounted on one side of the back side of the control panel body 1, one end of the worm 1003 penetrates the outside of the control panel body 1 and is installed with a knob 1001, and a worm gear 1002 is fixed to the end of the vertical shaft 8 close to the worm 1003, and the worm gear 1002 and the worm 1003 are meshed with each other. When operating the rotary drive structure 10, the staff turns the knob 1001, and the knob 1001 drives the worm 1003 to rotate, and then the worm 1003 causes the plug 9 and the vertical shaft 8 to rotate through the worm gear 1002. During this process, the worm 1003 and the worm gear 1002 have a self-locking function, which can maintain the angular rotation stability of the vertical shaft 8 and the plug 9, and the self-locking function can ensure that the vertical shaft 8 and the plug 9 maintain stability during rotation, avoid unnecessary swinging or shaking, thereby ensuring the accuracy and stability of the operation.

[0026] When the embodiment of the present application is in use, the staff first takes out the control panel body 1 and the circular back frame 2 to be assembled, so that the circular back frame 2 is pre-buried and bolted to the square hole on the wall. After the circular back frame 2 is fixed, the staff makes the back of the control panel body 1 enter the circular back frame 2 until the control panel body 1 is pushed to the limit position. At this time, the staff can manually screw the rotary drive structure 10, and the rotary drive structure 10 drives the vertical shaft 8 to rotate. In this process, the right-angle shaft seat 7 supports the rotation of the vertical shaft 8. When the vertical shaft 8 and the plug block 9 are rotated ninety degrees toward the direction of the square connecting column 301, the plug block 9 will enter the square connecting column 301. At this time, the plug block 9. The square connecting column 301 maintains an interference fit state, so that the control panel body 1 is installed in the circular back frame 2 in a relatively fixed state. When removing the control panel body 1 from the circular back frame 2, just follow the reverse steps. The control panel adopts a swing-and-clamp structure design. When installing and removing the heater control panel, the staff only needs to perform a twisting operation to complete the connection and removal. The operation is simple and convenient, and does not require additional tools and complicated operating steps. Compared with the method of forcible prying, the swing-and-clamp structure design can reduce the risk of damage to the heater control panel and the circular back frame 2, and will not cause additional pressure and damage to the equipment and the bracket, which is beneficial to extending the service life and stability of the equipment.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
