[0037] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1-Figure 11As shown, an embodiment of the utility model provides a switching electrical appliance, which includes a main body 1 and a protection module 2, and the protection module 2 is detachably arranged on the main body 1. Among them, the main body 1 is provided with at least one first limiting groove 11 and at least one second limiting groove 12 at intervals along the first direction (i.e., the X-axis direction). A pull rod 21, a first moving rod 22 and a second moving rod 23 are provided on the protection module 2, and the first moving rod 22 and the second moving rod 23 are respectively provided at two ends of the protection module 2 along the first direction. The pull rod 21 is rotatably provided on the protection module 2, and at least one of the first moving rod 22 and the second moving rod 23 is provided, and they are movably provided on the protection module 2 along the first direction. The first moving rod 22 can be movably inserted into or moved out of the first limiting groove 11 along the first direction, and the second moving rod 23 can be movably inserted into or moved out of the second limiting groove 12 along the first direction. The pull rod 21 is rotatably connected to the protection module 2, and rotating the pull rod 21 can switch it between a locked position and an unlocked position, such as Figure 5 As shown, when the pull rod 21 is in the locked position, the first moving rod 22 and the second moving rod 23 can be inserted into the first limiting groove 11 and the second limiting groove 12 respectively, so that the protection module 2 is connected to the body 1; Figure 6 As shown, when the pull rod 21 is in the unlocked position, the first moving rod 22 and the second moving rod 23 can respectively escape from the first limiting groove 11 and the second limiting groove 12, so that the protection module 2 is separated from the body 1, making disassembly more convenient.

[0039] The switch electrical appliance is configured with a pull rod 21, a first movable rod 22 and a second movable rod 23 on the protection module 2, and the pull rod 21 is rotated to enable the first movable rod 22 and the second movable rod 23 to be respectively inserted into or removed from the first limiting groove 11 and the second limiting groove 12, thereby realizing installation and disassembly of the protection module 2 and the main body 1. The disassembly and assembly can be realized without other tools, and the structure is simple and the operation is convenient.

[0040] Specifically, Figure 7 As shown, the pull rod 21 includes a middle plate 211 and side plates 212 arranged at both ends of the middle plate 211 along the second direction (i.e., the Y-axis direction), and the two side plates 212 facing each other are provided with protrusions 2121, and the two side surfaces of the protection module 2 along the second direction are provided with rotation holes, and the rotation holes are arranged on the side plates 212 near one end of the first moving rod 22, and the protrusions 2121 on the two side plates 212 are respectively rotatably connected with the two rotation holes to realize the rotation connection between the pull rod 21 and the protection module 2. The first direction and the second direction are perpendicular to each other.

[0041] Further, refer to Figure 5-Figure 7, a transmission rod 24 is also provided in the protection module 2 and is transmission-connected with the first moving rod 22. An extension rib 2122 is provided on the protrusion 2121. When the pull rod 21 is in the unlocked position, that is, when the pull rod 21 is rotated to switch from the locked position to the unlocked position, the extension rib 2122 rotates and presses the transmission rod 24, so that the transmission rod 24 moves toward the first moving rod 22 and drives the first moving rod 22 to move away from the first limiting groove 11 along the first direction, so that the first moving rod 22 escapes from the first limiting groove 11. Specifically, the transmission rod 24 is slidably arranged in the protection module 2 along the third direction. When the pull rod 21 rotates, the transmission rod 24 is driven by the extension rib 2122 to move toward the first moving rod 22 along the third direction (i.e., the Z-axis direction), so that the first moving rod 22 moves along the first direction and escapes from the first limiting groove 11. The first direction, the second direction, and the third direction are perpendicular to each other.

[0042] It can be understood that the rotating hole is provided with an extension hole to avoid the extension rib 2122 to achieve installation.

[0043] like Figure 8-Figure 9 As shown, the first moving rod 22 includes a first main body 221 and a first plug-in portion 222 that are interconnected. In order to facilitate the transmission rod 24 and the first moving rod 22 to abut against each other, the first main body 221 of the first moving rod 22 is provided with a first inclined surface 2211, and the transmission rod 24 is provided with a second inclined surface 241. When the transmission rod 24 moves toward the first moving rod 22 along the third direction, the first inclined surface 2211 and the second inclined surface 241 slide and abut against each other, so that the transmission rod 24 can drive the first moving rod 22 to move so that the first plug-in portion 222 of the first moving rod 22 disengages from the first limiting groove 11.

[0044] In order to realize that the first moving rod 22 can be automatically inserted into the first limiting groove 11 when the pull rod 21 is in the locked position, Figure 5 or Figure 6 A first elastic member 25 is further provided in the protection module 2 . When the pull rod 21 is in the locking position, the first elastic member 25 can elastically drive the first plug-in portion 222 of the first moving rod 22 to be plugged into the first limiting groove 11 .

[0045] Specifically, the first elastic member 25 can be selected as a tension spring or a rubber band, and the two ends of the first elastic member 25 are respectively connected to the first main body 221 of the first moving rod 22 and the inner wall of the protection module 2. When the pull rod 21 switches to the unlocking position, the transmission rod 24 moves along the third direction toward the first moving rod 22 and presses the first moving rod 22, driving the first moving rod 22 to overcome the elastic tension of the first elastic member 25, so that the first plug-in portion 222 of the first moving rod 22 can be disengaged from the first limiting groove 11; when the pull rod 21 switches to the locking position, the extension rib 2122 rotates in the opposite direction, the transmission rod 24 loses the pressing force, and the first moving rod 22 loses the pressing force of the transmission rod 24, so that the first plug-in portion 222 of the first moving rod 22 is inserted into the first limiting groove 11 under the elastic force of the first elastic member 25.

[0046] Refer to Figure 7 As shown, the middle plate 211 is provided with a pressing rod 2111. When the pull rod 21 is in the locked position, the pressing rod 2111 can press the second moving rod 23 to drive the second moving rod 23 to be inserted into the second limiting groove 12 along the first direction. The structure is simple and easy to operate.

[0047] Specifically, Figure 10-11 As shown, the second movable rod 23 includes a second main body 231 and a second plug-in portion 232 that are connected to each other. The second main body 231 of the second movable rod 23 is provided with a third inclined surface 2311, and the end of the pressure rod 2111 facing away from the middle plate 211 is provided with a fourth inclined surface 2111a. When the pull rod 21 switches to the locking position, the third inclined surface 2311 slides and abuts against the fourth inclined surface 2111a, so that the pressure rod 2111 drives the second movable rod 23 to move, so that the second plug-in portion 232 of the second movable rod 23 is plugged into the second limiting groove 12.

[0048] In order to realize that the second plug-in portion 232 of the second moving rod 23 can automatically disengage from the second limiting groove 12 when the pull rod 21 is in the unlocking position, Figure 5-Figure 6 A second elastic member 26 is further provided in the protection module 2 . When the pull rod 21 is in the unlocking position, the second elastic member 26 can elastically drive the second moving rod 23 to disengage from the second limiting groove 12 .

[0049] Specifically, the second elastic member 26 can be selected as a compression spring, and the second elastic member 26 is sleeved on the second plug-in portion 232 of the second moving rod 23, and the two ends of the second elastic member 26 elastically abut the second main body 231 of the second moving rod 23 and the protection module 2 respectively. When the pull rod 21 switches to the locked position, the pressing rod 2111 presses the second moving rod 23 so that the second moving rod 23 overcomes the elastic force of the second elastic member 26, and the second plug-in portion 232 of the second moving rod 23 is inserted into the second limiting groove 12; when the pull rod 21 switches to the unlocked position, the second moving rod 23 loses the pressing force of the pressing rod 2111, and the second moving rod 23 drives the second moving rod 23 under the elastic force of the second elastic member 26, so that the second plug-in portion 232 of the second moving rod 23 is out of the second limiting groove 12.

[0050] Refer to Fig.10 The second body 231 of the second moving rod 23 is provided with a limiting groove 2312, and the third inclined surface 2311 is provided in the limiting groove 2312. When the pull rod 21 switches to the locking position, the third inclined surface 2311 and the fourth inclined surface 2111a slide and abut, and the pressing rod 2111 is limited in the limiting groove 2312, and the structure is more stable.

[0051] It can be understood that the protection module 2 has first and second through holes at both ends along the first direction, which correspond to the first moving rod 22 and the second moving rod 23 , respectively. The first moving rod 22 and the second moving rod 23 are respectively inserted into the first and second through holes.

[0052] In order to prevent the second moving rod 23 from rotating when moving, two symmetrical anti-rotation protrusions 2321 are provided on the outer peripheral surface of the second plug-in portion 232 of the second moving rod 23, and two symmetrical anti-rotation grooves are provided on the inner wall of the second through hole of the protection module 2. When the second plug-in portion 232 of the second moving rod 23 is inserted into the second through groove, the two anti-rotation protrusions 2321 are respectively limited in the two anti-rotation grooves.

[0053] In this embodiment, two first moving rods 22 and two first limiting grooves 11 are provided, the two first moving rods 22 are provided on the protection module 2 along the second direction, the two first limiting grooves 11 are provided on the body 1 at intervals along the second direction, and the two first moving rods 22 can be respectively inserted into or removed from the two first limiting grooves 11; one second moving rod 23 and one second limiting groove 12 are provided. Of course, multiple first moving rods 22 and multiple first limiting grooves 11 can also be provided, and two or more second moving rods 23 and multiple second limiting grooves 12 can also be provided, and the number is not limited here.

[0054] In order to keep the position of the pull rod 21 stable when the pull rod 21 is in the locked position, Figure 7, a clamping boss 2123 is provided on one end of the side plate 212 of the pull rod 21 near the second moving rod 23, and a clamping groove is provided on one end of the protection module 2 near the second moving rod 23. When the pull rod 21 is in the locked position, the clamping boss 2123 can be clamped with the clamping groove to prevent the pull rod 21 from accidentally switching to the unlocked position. Of course, the clamping boss 2123 can also be provided on the protection module 2, and the clamping groove can be provided on the side plate 212 of the pull rod 21, which is not limited here.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
