[0055] Figure 6 yes Figure 5 The cross-sectional view along the 6-6' direction shown in the figure. Figure 7 yes Figure 5The diagram shows the state of the handle after it has been moved. Figure 8 yes Figure 6 The diagram shows the state of the disk component after it has been rotated in the first direction. Figure 9 yes Figure 6 The diagram shows the state of the disk component after it has been rotated in the second direction. Figures 6 to 9 As shown: The rotating part 200 includes a guide member 210, a handle 220, a disc member 230, a connector 240, an elastic member 250, and a clamping part 260.

[0056] The guide component 210 is an inverted U-shaped hollow cylindrical structure, consisting of an outer guide 211 and an inner guide 213 connected vertically. The inner and outer guides are two hollow cylinders. The lower end of the outer guide 211 has an annular bottom surface that connects to the inner guide. The annular bottom surface of the outer guide 211 contacts the upper surface of the cover 130. The inner guide 213 extends through the mounting hole 131 into the housing part 100.

[0057] The outer guide 211 and the inner guide 213 are coaxially arranged with the mounting hole 131, and the outer peripheral surface of the inner guide 213 is in contact with the inner wall of the mounting hole 131.

[0058] The outer guide 211 has a fixing hole 212 on its wall surface. The fixing hole 212 is arranged along the diameter direction of the outer guide 211, and the end of the fixing hole 212 on the inner side of the outer guide 211 is open.

[0059] The locking part 300 is inserted into the fixing hole 212 and fixedly connected to the outer guide 211. The locking part 300 includes a locking body 310 and a locking head 320. The locking body 310 is inserted into the fixing hole 212, and the locking head 320 is disposed at the end of the locking body 310. The locking head 320 is at least partially exposed inside the outer guide 211.

[0060] The handle 220 is disposed inside the outer guide 211 and partially protrudes from the upper end surface of the outer guide. The handle can move up and down within the outer guide and can rotate along the axis of the outer guide. For ease of gripping, the handle 220 may have a predetermined protruding structure. The rotation of the handle 220 can be accomplished by the user's grip and operation.

[0061] The disc-shaped component 230 is disposed inside the outer guide 211 and is coaxially arranged with the handle 220. The disc-shaped component 230 is located below the handle 220, and the lower end of the handle 220 is fixedly connected to the upper surface of the disc-shaped component 230. The handle 220 can drive the disc-shaped component 230 to rotate together. The outer diameter of the disc-shaped component 230 matches the inner diameter of the outer guide 211.

[0062] The disc-shaped component 230 has a first locking groove 231, a second locking groove 232, and a third locking groove 233 recessed from the edge of the disc towards the center on one side. The second and third locking grooves are symmetrically distributed on both sides of the first locking groove, and the first, second, and third locking grooves penetrate the upper and lower thickness portions of the disc-shaped component 230, respectively. Furthermore, the lengths of the second locking groove 232 and the third locking groove 233 can be longer than the first locking groove 231. The locking head 320 can be accommodated in any of the first, second, and third locking grooves.

[0063] The connector 240 is preferably a cylindrical structure, partially located in the inner guide 213. Its upper end is fixedly connected to the bottom surface of the disc-shaped component 230, and its lower end is fixedly connected to the clamping part 260 located below the inner guide 213. The outer diameter of the connector 240 matches the inner diameter of the inner guide 213.

[0064] The lower part of the connector 240 is also fitted with an anti-detachment component 241 located above the clamping part 260, and the upper end face of the anti-detachment component 241 contacts the lower end face of the inner guide. The interference of the anti-detachment component 241 restricts the vertical movement of the connector 240.

[0065] The elastic component 250 is fitted onto the upper part of the connector 240, and the upper and lower ends of the elastic component 250 are in contact with the disc-shaped component 230 and the outer guide annular end face, respectively.

[0066] The elastic member 250 is coaxially disposed with the connector 240 and surrounds the upper part of the connector 240. The elastic member 250 is an elastic body that is compressed vertically along the rotation axis of the rotating part 200 and has an elastic recovery function. Preferably, the elastic member 250 is a compression spring structure.

[0067] The handle 220, disc-shaped component 230, connector 240, and clamping part 260 are operating components C that rotate integrally with each other in the coaxial direction. Furthermore, the operating component C can also move up and down along the guide portion.

[0068] For reference Figure 5 and Figure 6 As shown, when the locking head 320 is accommodated in the first locking groove 231, the interference between the locking head 320 and the first locking groove 231 restricts the rotation of the operating component C. At this time, the engagement state between the locking head 320 and the first locking groove 231 can be maintained by the elastic recovery action of the elastic component 250.

[0069] like Figure 5 and Figure 7As shown, when pressure is applied to the handle 220 toward the interior of the housing 100, the first locking groove 231 separates from the locking head 320 along that direction. Therefore, the interference caused by the locking head 320 is released, and the operating member C becomes rotatable. During this process, the pressure applied to the handle 220 causes the elastic member 250 to be compressed between the disc-shaped member 230 and the bottom surface of the outer guide 211. At this time, as... Figure 6 , Figure 8 or Figure 9 As shown, the disc-shaped component can be rotated in either the first or second direction by operating the rotating handle 220.

[0070] like Figure 3 As shown, the position of switch 10 corresponds to the middle portion of the entire movable trajectory of switch 10. Furthermore, the middle position of switch 10 can be defined as trip position T as needed. In this trip position T, the locking head 320 is accommodated in the first locking groove 231.

[0071] like Figure 8 As shown, when the disc-shaped component 230 rotates to the position of... Figure 3 When the switch 10 is in the open position N, the locking head 320 can be accommodated in the second locking groove 232. Strictly speaking, the locking head 320 will be positioned at the lower part of the length region of the second locking groove 232 so as not to be interfered with by the second locking groove 232. As the clamping part 260 rotates together with the disc-shaped part 230, the switch 10 will be moved to the open position N.

[0072] like Figure 9 As shown, when the disc-shaped component 230 rotates to the position of... Figure 3 When the closed position F is shown, the locking head 320 can be accommodated in the third locking groove 233. Strictly speaking, the locking head 320 will be positioned at the lower part of the length region of the third locking groove 233 so as not to be interfered with by the third locking groove 233. As the clamping part 260 rotates together with the disc-shaped part 230, the switch 10 will be moved to the closed position F.

[0073] like Figure 7 and Figure 5 As shown, when the pressure applied to the handle 220 is released, the elastic member 250 regains its elasticity. Through this elastic restoring force, the operating member C moves upward, and the first, second, and third locking grooves 231, 232, and 233 move upward to accommodate the locking head 320.

[0074] Therefore, when pressure is applied to the handle 220, the engagement between the first, second, and third locking grooves 231, 232, and 233 and the locking head 320 is released, thereby allowing the switch 10 to switch to the trip, open, or closed position. Subsequently, after the pressure on the handle 220 is released, the first, second, and third locking grooves 231, 232, and 233 re-engage with the locking head 320, thereby restricting the rotation of the handle 220 and the movement of the switch 10.

[0075] Figure 10 A front view of one embodiment of the clamping part and the switch is shown. Figure 11 Showing Figure 10 The sectional view shown in the 11-11' direction. Figure 12 Showing Figure 11 The clamping part is rotating in the first direction. Figure 13 Showing Figure 11 The clamping part is rotating in the second direction.

[0076] like Figures 10 to 13 As shown, the clamping part 260 is engaged with the bottom surface of the connector 240. Furthermore, the clamping part 260 is arranged inside the housing component 100 and adjacent to the switch 10. The clamping part 260 has an inverted U-shaped groove structure, consisting of a connecting plate 261, a first pressure plate 262, and a second pressure plate 263. The first and second pressure plates 262 and 263 are vertically arranged on both sides of the connecting plate 261. The connecting plate 261 is connected to the bottom surface of the connector 240, and the bottom surface of the connecting plate 261 faces the free end face of the switch 10. The second pressure plate 263 is symmetrical to the first pressure plate 262. The actuating head of the switch 10 is accommodated between the first and second pressure plates.

[0077] like Figure 11 and Figures 11 to 13 As shown, when the handle 220 is rotated in the first direction, the clamping part 260 also rotates in the same direction. The switch 10 is pushed by the rotating first pressure plate 262 and moves in the first direction. Therefore, the switch 10 will move from the trip position T to the open position N.

[0078] Figure 11 The reference axis X shown can be defined as the central rotation axis of the entire operating component C.

[0079] On the contrary, such as Figure 13 and ​ As shown, when the handle 220 rotates in the second direction, the clamping part 260 will rotate in the same direction. The switch 10 is pushed by the rotating second pressure plate 263 and moves in the second direction. Therefore, the switch 10 will move from the trip position T to the closed position F. The movement trajectory of the switch 10 can be regarded as the tangent to the rotation trajectory of the clamping part 260.

[0080] Furthermore, each position transition process of the aforementioned switch 10 can be performed in reverse order. Similarly, the transition process from the open position N to the closed position F and its reverse process can also be freely performed.

[0081] In summary, the main technical concept of this utility model is to provide a switch protective housing. Referring to the drawings, the embodiments described are only partial embodiments. Those skilled in the art can make various substitutions with the same or equivalent technical means based on the technical concept of this utility model. All technical solutions obtained by using the same or equivalent technical means are within the scope of protection of the claims of this utility model.
