Description

Technical Field

[0001] The invention particularly relates to a switch protection shell for protecting a control switch. Background Art

[0002] In order to protect important equipment / components, a shell with explosion-proof, waterproof, pressure-resistant and other properties, as well as impact resistance, sealing and other protective properties is usually used. As an example of such a protective shell, the existing Korean Publication Patent No. 10-2016-0049920 discloses an explosion-proof shell for a surveillance camera. In addition, the document also discloses a light-transmitting means in the explosion-proof shell. By ensuring light transmittance, the surveillance camera placed inside the explosion-proof shell can take pictures. On the other hand, according to actual needs, it may be necessary to directly operate the equipment / components placed inside the protective shell. Accordingly, the switches used for the operation of important control functions must be protected from the influence of external dangerous factors, and the control switches must be allowed to operate freely. However, the prior art documents do not disclose a solution that allows the operation of protected objects such as control switches, which leads to considerable difficulties in the operation of protected objects.

[0003] [Prior art literature] Korean Patent Publication No. 10-2016-0049920 Summary of the invention

[0004] In view of the defects in the prior art, an object of the present invention is to provide a switch protection shell which can protect control switches of various devices and components and allow the switches to be operated freely.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: The switch protection shell provided by the present invention comprises a housing portion for accommodating a switch, a rotating portion and a locking portion, wherein the rotating portion moves the switch in the housing portion to a tripping, opening or closing position when rotating, and the locking portion is used to allow and limit the rotation of the rotating portion; The housing portion has an open end, and the open end is closed by a housing cover; The rotating part includes a guide component, an elastic component and an operating component, and the operating component is composed of a handle, a disc component, a connecting piece and a clamping part that are sequentially distributed and fixedly connected up and down; the guide component is an inverted convex hollow cylindrical structure, which is formed by an outer guide and an inner guide connected up and down, and the inner and outer guides are two hollow cylinders, and the lower end of the outer guide has an annular bottom surface connected to the inner guide, the inner guide penetrates the shell cover and enters the shell part, and the outer guide is located outside the shell cover; The handle and the disc component are located inside the outer guide, and the handle part protrudes from the upper end surface of the outer guide; the connecting part is located in the inner guide, and its upper end is connected to the bottom surface of the disc-shaped component, and its lower end is connected to the clamping part located below the inner guide; the elastic component is sleeved on the periphery of the connecting part, and its upper and lower ends are in contact with the annular end surfaces of the disc-shaped component and the lower end of the outer guide respectively; One side of the disc-shaped component is provided with a first, a second and a third locking groove which is recessed from the edge of the disc body to the central part, wherein the second and the third locking grooves are located on both sides of the first locking groove and are symmetrically distributed; the corresponding disc component on the outer guide is provided with a locking portion protruding toward the inner part of the outer guide, and the locking portion is accommodated in any one of the first, the second and the third locking grooves; When the handle is pressed into the shell, the operating component moves downward and compresses the elastic component, and the locking part disengages from the locking groove. At this time, the handle is turned, and the operating component rotates as a whole, and the toggle switch moves to the tripping, opening or closing position when the clamping part rotates; when the switch moves to the target position and the pressure applied to the handle is released, the elastic component restores its elasticity, driving the operating component to move upward, and the locking part is accommodated in any one of the first, second, and third locking grooves, thereby limiting the rotation of the operating component.

[0006] The lower part of the connecting piece is also covered with an anti-slip component located above the clamping part, the upper end surface of the anti-slip component is in contact with the lower end surface of the inner guide, and the anti-slip component limits the position of the connecting piece moving up and down.

[0007] The operating member can move up and down along the guide member, and can rotate along the axis of the guide member.

[0008] The first, second and third locking grooves penetrate through upper and lower thickness portions of the disc-shaped component 230 respectively.

[0009] Furthermore, the lengths of the second and third locking grooves are greater than the length of the first locking groove.

[0010] The clamping portion is an inverted U-shaped groove structure, which is composed of a connecting plate, a first pressure plate and a second pressure plate. The connecting plate is connected to the bottom surface of the connecting piece. The first and second pressure plates are symmetrically distributed and vertically set on both sides of the connecting plate. The toggle head of the switch is accommodated between the first and second pressure plates.

[0011] The beneficial effects of the present invention are as follows: The switch protection shell provided by the present invention comprises a housing portion for accommodating a switch, a rotating portion and a locking portion. The switch is arranged inside the housing portion, thereby ensuring the safety of the switch.

[0012] At the same time, the rotating part passes through the shell part, with the upper end located outside the shell part and the lower end extending into the shell part. A handle is provided at the upper end of the rotating part. By rotating the handle provided outside the shell part, the switch can be conveniently operated to move to the tripping, opening or closing position, thereby improving the convenience of using the switch.

[0013] In addition, the present invention also provides a locking portion for allowing / locking the rotation of the handle according to the pressurization / release of the handle. Through this design, the operation of the handle becomes simpler and more convenient, and also can prevent misoperation.

[0014] At the same time, the moving track of the switch is the tangent of the rotating track of the handle, and the operating structure in which the rotating track of the handle intersects with the moving track of the switch is realized. In this way, the use of complex components such as gears is reduced, thereby further improving the simplicity of production. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figures 1 to 5As shown, the switch protection shell 1000 provided by the present invention includes a shell portion 100, a rotating portion 200 and a locking portion 300. The shell portion 100 has an internal cavity for accommodating the switch 10. In addition, the shell portion 100 can be a shell with multiple protection functions such as explosion-proof, waterproof, and pressure-proof. The shell portion 100 includes a bottom 110, a side wall portion 120 and a shell cover 130. The bottom 110 defines the bottom surface of the shell structure, the side wall portion 120 stands along the upper edge of the bottom 110, and the side wall portion 120 has a specific shape for sealing. The shell cover 130 is arranged at the open end of the side wall portion 120 to close the internal cavity in the side wall portion 120.

[0019] The housing cover 130 is provided with a mounting hole 131 penetrating the cover body from top to bottom. The mounting hole 131 enables the inside and outside of the housing portion 100 to communicate with each other.

[0020] In this embodiment, the switch 10 can be installed in a separate control box 11. The control box 11 can send a control command to a control target (not shown) according to the position of the switch 10. The control box 11 can also be electrically connected to the control target (not shown).

[0021] Figure 6 yes Figure 5 The cross-sectional view in the 6-6' direction is shown in FIG. Figure 7 yes Figure 5 The state diagram after the handle is moved is shown in . Figure 8 yes Figure 6 FIG. 4 is a diagram showing a state in which the disc component is rotated in a first direction. Fig. 9 yes Figure 6 The state diagram of the disc component after rotating in the second direction shown in FIG. Figures 6 to 9 As shown, the rotating part 200 includes a guide component 210 , a handle 220 , a disc component 230 , a connecting member 240 , an elastic component 250 and a clamping part 260 .

[0022] The guide component 210 is an inverted convex hollow cylindrical structure, which is formed by an outer guide 211 and an inner guide 213 connected up and down. The inner and outer guides are two hollow cylinders. The lower end of the outer guide 211 has an annular bottom surface connected to the inner guide. The annular bottom surface of the outer guide 211 contacts the upper surface of the shell cover 130, and the inner guide 213 passes through the mounting hole 131 and extends into the shell body 100.

[0023] 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 contacts the inner wall of the mounting hole 131 .

[0024] A fixing hole 212 is provided on the wall surface of the outer guide 211 . 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.

[0025] 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 arranged at the end of the locking body 310. The locking head 320 is at least partially exposed inside the outer guide 211.

[0026] 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 in the outer guide and can rotate along the axis of the outer guide. In order to facilitate holding, the handle 220 can form a predetermined protruding structure. The rotation operation of the handle 220 can be completed by the user's holding and operation.

[0027] The disc-shaped component 230 is arranged 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, and 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.

[0028] The disc-shaped component 230 has a first locking groove 231, a second locking groove 232 and a third locking groove 233 formed by being recessed from the edge of the disc body to the center part, 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 respectively penetrate the upper and lower thickness parts of the disc-shaped component 230. 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.

[0029] The connecting member 240 is preferably a cylindrical structure, partially located in the inner guide 213, with its upper end fixedly connected to the bottom surface of the disc-shaped component 230 and its lower end fixedly connected to the clamping portion 260 located below the inner guide 213. The outer diameter of the connecting member 240 matches the inner diameter of the inner guide 213.

[0030] The lower part of the connecting member 240 is also covered with an anti-slip component 241 located above the clamping portion 260, and the upper end surface of the anti-slip component 241 contacts the lower end surface of the inner guide. Through the interference of the anti-slip component 241, the position of the connecting member 240 moving up and down is limited.

[0031] The elastic component 250 is sleeved on the upper part of the connecting member 240, and the upper and lower ends of the elastic component 250 are in contact with the disc-shaped component 230 and the annular end surface of the outer guide respectively.

[0032] The elastic component 250 is coaxially arranged with the connecting member 240 and surrounds the upper portion of the connecting member 240. The elastic component 250 is an elastic body that is compressed up and down along the rotation axis direction of the rotating part 200 and has an elastic recovery function. Preferably, the elastic component 250 is a compression spring structure.

[0033] The handle 220, the disk-shaped component 230, the connecting member 240 and the clamping portion 260 form an operating component C that rotates coaxially with each other. In addition, the operating component C can also move up and down along the guide portion.

[0034] As 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 member 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 effect of the elastic member 250 .

[0035] like Figure 5 and Figure 7 As shown in FIG. 1 , when the handle 220 applies pressure toward the inside of the housing 100, the first locking groove 231 separates from the locking head 320 in that direction. Therefore, the interference effect of the locking head 320 is released, and the operating component C is transformed into a rotatable state. In this process, the pressure applied to the handle 220 causes the elastic component 250 to be compressed between the disc-shaped component 230 and the bottom surface of the outer guide 211. At this time, as shown in FIG. Figure 6 , Figure 8 or Fig. 9 As shown, by operating the rotating handle 220, the disc-shaped component can be rotated in the first direction or the second direction.

[0036] like Figure 3 As shown, the position of the switch 10 corresponds to the middle part of the entire movable track of the switch 10. In addition, as required, the middle position of the switch 10 can be defined as a trip position T. In the trip position T, the locking head 320 is accommodated in the first locking groove 231.

[0037] like Figure 8 As shown, when the disk-shaped member 230 rotates to Figure 3When the switch 10 in the embodiment of the present invention is moved to the open position N corresponding to the switch 10 in the embodiment of the present invention, the locking head 320 can be accommodated in the second locking groove 232. Strictly speaking, the locking head 320 will be arranged at the lower part of the length area of ​​the second locking groove 232 so as not to be interfered by the second locking groove 232. As the clamping portion 260 rotates together with the disc-shaped component 230, the switch 10 will be moved to the open position N.

[0038] like Fig. 9 As shown, when the disk-shaped member 230 rotates to Figure 3 , the locking head 320 can be accommodated in the third locking groove 233. Strictly speaking, the locking head 320 will be arranged at the lower part of the length area of ​​the third locking groove 233 so as not to be interfered by the third locking groove 233. As the clamping portion 260 rotates together with the disc-shaped component 230, the switch 10 will be moved to the closed position F.

[0039] like Figure 7 and Figure 5 As shown, when the pressure applied to the handle 220 is released, the elastic member 250 will restore 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.

[0040] Therefore, when pressure is applied to the handle 220, the first, second, and third locking grooves 231, 232, and 233 are released from the locking head 320, so that the switch 10 can be switched 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 are re-engaged with the locking head 320, thereby restricting the rotation of the handle 220 and the movement of the switch 10.

[0041] Fig.10 A front view of one embodiment of a clamp and switch is shown. Fig.11 Shows Fig.10 A cross-sectional view along the direction 11-11' is shown in FIG. Fig.12 Shows Fig.11 The middle clamping portion is rotated in the first direction. Fig.13 Shows Fig.11 The middle clamping portion is rotated in the second direction.

[0042] like Figures 10 to 13As shown, the clamping portion 260 is combined with the bottom surface of the connecting member 240. In addition, the clamping portion 260 is arranged inside the housing component 100 and adjacent to the switch 10. The clamping portion 260 is an inverted U-shaped groove structure, which is composed of a connecting plate 261, a first pressing plate 262 and a second pressing plate 263. The first and second pressing plates 262 and 263 are vertically set up on both sides of the connecting plate 261. The connecting plate 261 is connected to the bottom surface of the connecting member 240. The bottom surface of the connecting plate 261 is opposite to the free end surface of the switch 10, and the second pressing plate 263 is symmetrical to the first pressing plate 262. The toggle head of the switch 10 is accommodated between the first and second pressing plates.

[0043] like Fig.11 and Fig.12 As shown, when the handle 220 rotates in the first direction, the clamping portion 260 also rotates in the same direction. The switch 10 is pushed by the rotating first pressing plate 262 and moves in the first direction. Therefore, the switch 10 moves from the trip position T to the open position N.

[0044] Figures 11 to 13 The reference axis X shown in FIG. 1 can be defined as the central rotation axis of the operating member C as a whole.

[0045] On the contrary, Fig.11 and Fig.13 As shown, when the handle 220 rotates in the second direction, the clamping portion 260 will rotate in the same direction. The switch 10 will be pushed by the rotating second pressing plate 263 and move 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 a tangent to the rotation trajectory of the clamping portion 260.

[0046] In addition, each position conversion process of the switch 10 described above can be performed in reverse order. Similarly, the conversion process from the open position N to the closed position F and its reverse process can also be freely performed.

[0047] In summary, the main technical idea of ​​the present invention is to provide a switch protection case. Referring to the drawings, the embodiments described are only partial embodiments, and those skilled in the art can make a variety of replacements with the same or equivalent technical means based on the technical idea of ​​the present invention. All technical solutions obtained by replacing the same or equivalent technical means belong to the scope of protection of the claims of the present invention.
