[0004] This application provides a fixing device for a control switch, providing another way to fix the control switch.

[0005] This application provides a fixing device for a control switch, adopting the following technical solution:

[0006] The fixing device for the control switch is installed on the conversion box. The conversion box is provided with an installation slot. When the control switch is installed on the conversion box, the control part of the control switch is exposed outside the conversion box through the installation slot. The fixing device includes a protection panel and a protection cover rotatably installed on the protection panel. The protection panel is provided with a through slot. The protection panel is installed on the outer wall of the conversion box. The through slot communicates with the installation slot. The control part of the control switch extends into the through slot. A fixing member is installed between the protection cover and the protection panel. The fixing device further includes an installation frame. The installation frame is installed inside the conversion box. A limiting slot is provided on one side of the control switch. The installation frame is embedded in the limiting slot.

[0007] By adopting the above technical solution, through the design of the installation slot on the conversion box, the control part of the control switch can be conveniently exposed outside the box for operation. At the same time, the combination of the protection panel and the protection cover provides effective protection for the control switch. The setting of the fixing device not only ensures the stable installation of the control switch, but also enhances the structural stability and safety through the cooperation of the limiting slot and the installation frame. After operation, the user can conveniently control the switch, and at the same time, the design of the protection panel and the protection cover effectively prevents direct contact from the outside and accidental damage to the control switch.

[0008] Optionally, the fixing device further includes a connecting plate and a first locking member. The connecting plate is installed inside the conversion box. The first locking member passes through the connecting plate and the conversion box and is fixedly connected to the protection panel.

[0009] By adopting the above technical solution, on the basis of the original fixing device, a connecting plate and a first locking member are added, making the connection between the protection panel and the conversion box more firm. This design further improves the stability of the overall structure, reduces the risk of loosening caused by vibration or impact, and ensures the reliability and safety of the control switch during long-term use.

[0010] Optionally, the mounting bracket includes a mounting strip and limiting strips mounted on the upper and lower side walls of the mounting strip. The length directions of the mounting strip and the limiting strips are the same. A vertical plane in the same direction of the mounting strip and the limiting strips is not in the same vertical plane. The width of the limiting groove gradually decreases towards the notch direction, and the limiting strip abuts against the bottom wall of the limiting groove.

[0011] By adopting the above technical solution, the design of the mounting bracket includes a mounting strip, limiting strips and a mounting plate. These components work together to achieve precise positioning and stable support of the control switch. The cooperation between the limiting groove and the limiting strip, especially the design of the gradually decreasing width of the limiting groove, effectively prevents the control switch from moving in the vertical direction, improving the installation accuracy and stability. The connection between the mounting plate and the connecting plate through the second locking member further enhances the overall strength of the structure.

[0012] Optionally, the mounting bracket further includes a mounting plate, which is mounted at both ends of the mounting strip in the length direction. A second locking member is installed between the mounting plate and the connecting plate.

[0013] Optionally, the second locking member is a bolt, and a nut is embedded in the connecting plate. The second locking member is threadedly connected to the nut.

[0014] By adopting the above technical solution, using a bolt and a nut as the second locking member and embedding the nut in the connecting plate, the mounting bracket realizes a quick and reliable connection. In addition, the design that the nut part extends out of the connecting plate and sleeves a sleeve not only facilitates the insertion and tightening of the bolt, but also can reduce the wear between the nut and the bolt to a certain extent and extend the service life.

[0015] Optionally, the nut part of the connecting plate extends out of the connecting plate, and the nut extending out of the connecting plate sleeves a sleeve. The second locking member extends into the sleeve and is threadedly connected to the nut.

[0016] By adopting the above technical solution, the way that the bolt passes through the sleeve and is threadedly connected to the nut not only simplifies the installation process, but also improves the tightness and stability of the connection. The presence of the sleeve makes the tightening process of the bolt smoother, reduces the risk of thread damage caused by directly operating the bolt, and enables the mounting plate to be stably connected to the connecting plate while reducing the contact with the connecting plate.

[0017] Optionally, the mounting strip and the mounting plate are both provided with grooves.

[0018] By adopting the above technical solution, the grooves provided on the mounting strip and the mounting plate can be used for wiring or the installation of other accessories. This design improves the space utilization rate, making the overall structure more compact and tidy. At the same time, the grooves may also be part of the weight reduction design, reducing the overall weight and facilitating installation and transportation.

[0019] Optionally, the protection panel extends a connecting convex ring, and the connecting convex ring is snap-fitted into the mounting groove.

[0020] By adopting the above technical solution, the design that the connecting convex ring extended by the protection panel is snap-fitted into the mounting groove provides a quick and simple installation method. This snap-fitting structure is not only firmly fixed, but also convenient for disassembly and maintenance. When it is necessary to replace or repair the control switch, the protection panel can be easily removed by unlocking the snap-fitting structure.

[0021] In summary, the present application includes at least one of the following beneficial effects:

[0022] 1. The entire fixing device realizes the high integration and stable installation of the control switch through multi-level connection and fixing structures. This design significantly improves the overall stability and reliability of the device, reducing the risk of loosening and damage caused by vibration or impact;

[0023] 2. The control part of the control switch is exposed outside the box through the mounting groove, facilitating operation by the user.

Detailed implementation manners

[0032] The following further describes the present application in detail Figure 1-7 with reference to the accompanying drawings.

[0033] The embodiment of the present application discloses a fixing device for a control switch. Referring to Figure 1 , the fixing device of the control switch is installed on the conversion box 10. The fixing device includes a mounting bracket 30, and the control switch 20 is installed in the conversion box 10 through the mounting bracket 30.

[0034] Referring to Figure 2 , a limiting groove 21 is provided on one side wall of the control switch 20. The two ends of the limiting groove 21 in the length direction extend along the switch distribution direction of the control switch 20. The notch of the limiting groove 21 faces away from the control part of the control switch 20. The width of the limiting groove 21 gradually decreases towards the notch. The cross-section of the limiting groove 21 is a dovetail groove. The limiting groove 21 of the control switch 20 is a prior art. Generally, the purchased control switch 20 is equipped with the limiting groove 21, mainly for facilitating the installation of the control switch 20.

[0035] Referring to Figure 2 , the mounting bracket 30 includes a mounting strip 31 and a limiting strip 32. Widened plates 33 extend on the upper and lower side walls of the mounting strip 31, so that the cross-section of the mounting strip 31 is a U-shaped structure. The limiting strip 32 is fixedly installed on the widened plate 33. The limiting strip 32 and the mounting strip 31 are in the same length direction, and a vertical plane of the limiting strip 32 and the mounting strip 31 in the same direction is not in the same vertical plane.

[0036] Referring to Figure 1 andFigure 2 When the mounting bracket 30 is connected to the control switch 20, forcefully snap the mounting strip 31 into the limiting groove 21. The limiting strip 32 is appropriately deformed and squeezed into the limiting groove 21, so that a vertical surface of the limiting strip 32 abuts against the bottom wall of the limiting groove 21. The limiting strip 32 is not easily separated from the control switch 20, enabling the control switch 20 to maintain a stable connection relationship with the mounting bracket 30. Then the mounting bracket 30 is fixedly connected to the conversion box 10, so that the control switch 20 is installed on the conversion box 10.

[0037] Refer to Figure 3 On the conversion box 10, there is an installation groove 11 for the control part of the control switch 20 to extend out of the conversion box 10, so that the control part of the control switch 20 can be conveniently exposed outside the box for operation.

[0038] To effectively prevent direct contact from the outside and accidental damage to the control switch 20, the fixing device further includes a protection panel 40 and a protection cover 50 rotatably mounted on the protection panel 40. The protection panel 40 is installed on the outer wall of the conversion box 10. The protection panel 40 is provided with a through groove 41, and the through groove 41 communicates with the installation groove 11. A part of the control part of the control switch 20 extends into the through groove 41. When the protection cover 50 is closed, a fixing member 6 is installed between the protection cover 50 and the protection panel 40. The fixing member 6 is preferably a bolt. The protection panel 40 is embedded with a nut 7 or provided with a threaded hole. When the bolt is threadedly connected to the protection panel 40, the protection cover 50 protects the control switch 20. The protection cover 50 can also be made of an anti-reflective PC board, which is convenient for people to know the specific working state of the control part of the control switch 20.

[0039] Refer to Figure 4 Furthermore, in order to stably install the protection panel 40 on the conversion box 10, first, a connecting convex ring 42 is integrally formed on one side of the protection panel 40, and the outer peripheral side of the connecting convex ring 42 is clamped in the installation groove 11. The fixing device further includes a connecting plate 80 and a first locking member 91. The connecting plate 80 is a rectangular ring structure, and the connecting plate 80 is attached to the inner wall of the conversion box 10. The first locking member 91 is also preferably a bolt. The bolt passes through the connecting plate 80 and is threadedly connected to the conversion box 10 and the protection panel 40, so that the protection panel 40 is further fixed on the conversion box 10, reducing the risk of loosening caused by vibration or impact.

[0040] Refer to Figure 5 and Figure 6, the mounting bracket 30 is also fixedly installed in the conversion box 10 through the connecting plate 80. The mounting bracket 30 further includes a mounting plate 34. There are two mounting plates 34, which are respectively installed at both ends of the mounting strip 31 in the length direction. When the mounting strip 31 is embedded in the limiting groove 21 of the control switch 20, the mounting plate 34 is attached to the side wall of the control switch 20. One end of the mounting plate 34 away from the mounting strip 31 is bent. A second locking member 92 is installed between the bent portion of the mounting plate 34 and the connecting plate 80.

[0041] Refer to Figure 6 and Figure 7 , the second locking member 92 is a bolt. A nut 7 for threaded connection with the second locking member 92 is embedded in the connecting plate 80. The second locking member 92 is threadedly connected with the nut 7, so that the mounting bracket 30 and the connecting plate 80 are stably connected. The nut 7 on the connecting plate 80 partially extends out of the connecting plate 80. A sleeve 81 is sleeved on the nut 7 extending out of the connecting plate 80. The sleeve 81 is fixedly inserted into the connecting plate 80. The second locking member 92 extends into the sleeve 81 and is threadedly connected with the nut 7. The setting of the sleeve 81 enables the mounting plate 34 to be both stably connected to the connecting plate 80 and to reduce contact with the connecting plate 80.

[0042] Refer to Figure 6 , in order to facilitate the better removal of the mounting bracket 30 outside the conversion box 10 and also to reduce the overall weight of the mounting bracket 30, grooves 35 are provided on both the mounting strip 31 and the mounting plate 34.

[0043] The implementation principle of the fixing device of the control switch in the embodiment of the present application is as follows:

[0044] The protective panel 40 already with the protective cover 50 can be first fixedly installed on the conversion box 10. The first locking member 91 passes through the connecting plate 80 and the conversion box 10 and is threadedly connected to the corresponding threaded hole of the protective panel 40, so that the protective panel 40 is first fixed on the conversion box 10. Then, the mounting strip 31 and the limiting strip 32 of the mounting bracket 30 are snapped into the limiting groove 21 of the control switch 20, and the control part of the control switch 20 extends into the protective panel 40. Finally, the mounting bracket 30 and the connecting plate 80 are fixedly connected, so that the control switch 20 is firmly installed on the conversion box 10. The installation and disassembly of the entire fixing device are relatively simple, and the connection firmness is also guaranteed.

[0045] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
