Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a high-transmittance emergency stop switch. Background Technology

[0002] An emergency stop switch is a type of master control electrical appliance. When a machine is in a dangerous state, the emergency stop switch cuts off the power supply, stopping the equipment and protecting personnel and equipment. A traditional emergency stop switch consists of a housing, a contact mechanism inside the housing, an operating knob inside the housing for operating the contact mechanism, and an actuation cover on the operating knob. A reset spring connects the operating knob to the housing. Rotating the cover moves the operating knob downwards, triggering the contact mechanism to switch the circuit. However, existing emergency stop switches have an unreasonable structural design and poor light transmission, making it difficult to clearly indicate the emergency stop switch's position. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high light transmittance emergency stop switch with excellent light transmittance, which can clearly indicate the position of the emergency stop switch, is more suitable for darker environments, and has a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve its technical problem is a high-transmittance emergency stop switch, including a contact mechanism and an operating mechanism. The operating mechanism is arranged above the contact mechanism and is used to enable the contact mechanism to switch circuits. The operating mechanism includes a core seat and a toggle cap. The toggle cap is connected above the core seat. An indicator light is also provided above the contact mechanism. First electrical contacts are provided on both sides of the indicator light. A first mounting cavity is radially provided on the core seat. An elastic positioning component is provided between the toggle cap and the core seat and in the first mounting cavity. The elastic positioning component is used to cooperate with the emergency stop locking and rotation reset of the core seat. A first light-transmitting cavity is also axially provided through the core seat. An axially eccentric second light-transmitting cavity is provided in the first light-transmitting cavity. Both the first light-transmitting cavity and the second light-transmitting cavity are used to cooperate with the indicator light. The first mounting cavity is radially eccentrically arranged and located on the radial side of the second light-transmitting cavity. The first mounting cavity and the second light-transmitting cavity are offset.

[0005] The advantages of the above technical solution are as follows: By setting a first mounting cavity on the core seat and setting an elastic positioning component between the toggle cap and the core seat, and within the first mounting cavity, when in use, pressing the toggle cap causes the core seat to move downwards. After the core seat moves to its position, the elastic positioning component can put the core seat in the emergency stop locked position. When reset is required, twisting the toggle cap causes the core seat to rotate, and the elastic positioning component can release the emergency stop lock. At the same time, after the core seat rotates to its position, the elastic positioning component can also reset the core seat and the toggle cap. Furthermore, by setting an axially penetrating first light-transmitting cavity on the core seat and setting an axially eccentric second light-transmitting cavity within the first light-transmitting cavity, and setting the first mounting cavity radially eccentrically on one side of the second light-transmitting cavity, the first mounting cavity and the second light-transmitting cavity are offset. Therefore, the components of the elastic positioning component within the first mounting cavity will not obstruct the first and second light-transmitting cavities, thus ensuring good light transmission performance. The toggle cap can also be made of a light-transmitting material, thus effectively indicating the position of the emergency stop switch and making it more suitable for darker environments. The structural design is reasonable.

[0006] Furthermore, the elastic positioning assembly includes a positioning slide rod, a compression spring, and a rotary compression spring. The compression spring and the positioning slide rod are disposed inward and outward at the first mounting cavity. A ratchet is provided in the inner cavity of the first outer shell at the lower part of the first mounting cavity. The ratchet is used to cooperate with the positioning slide rod. The first outer shell is also provided with a first positioning part, and the core seat is provided with a second positioning part. The first positioning part and the second positioning part are respectively connected to the two ends of the rotary compression spring.

[0007] The advantages of the above technical solution are as follows: By setting the first positioning part and the second positioning part, the rotary compression spring can effectively define the position. During the process of the torsion cap driving the core seat to move downward, the rotary compression spring will first compress. After the core seat moves to the position, the compression spring causes the positioning slide rod to move out of the first mounting cavity and cooperate with the ratchet, thereby completing the emergency stop lock. The ratchet design ensures that the torsion cap can only rotate in one direction. When it is necessary to release the emergency stop lock, rotating the torsion cap will drive the core seat to rotate. At this time, the rotary compression spring will generate a rotational restoring force. During the process of the torsion cap driving the core seat to rotate, the positioning slide rod will move back into the first mounting cavity under the action of the ratchet until it is fully inserted. At this time, the rotary compression spring releases the rotational restoring force and the compression restoring force, thereby driving the torsion cap and the core seat to rotate upward and reset.

[0008] Furthermore, the upper end of the first housing is provided with a first mounting ring edge and a second mounting ring edge, the rotary compression spring is disposed between the first mounting ring edge and the second mounting ring edge, and the first mounting ring edge is also used to cooperate with the positioning slide rod, and the second mounting ring edge is also used to cooperate with the torsion cap.

[0009] The advantages of the above technical solution are as follows: by setting the first mounting ring edge and the second mounting ring edge, a good positional limitation is formed for the rotary compression spring, the use effect of the rotary compression spring is better, and the first mounting ring edge also enables the positioning slide rod to be stably set at the first mounting cavity, and the second mounting ring edge enables the installation and use of the torsion cap to be more reliable. The overall structural design is reasonable.

[0010] Furthermore, a sealing ring groove is provided on the outer peripheral wall surface of the core seat, the sealing ring groove is positioned above the first mounting cavity, and a sealing element is provided inside the sealing ring groove.

[0011] The advantages of adopting the above technical solution are: the cooperation between the sealing ring groove and the sealing element can effectively prevent dust intrusion, making it safer to use, and the structural design is reasonable.

[0012] Furthermore, the twisted cap is provided with a third light-transmitting cavity, which cooperates with the first light-transmitting cavity and the second light-transmitting cavity, and a light-transmitting protective cover is provided at the third light-transmitting cavity.

[0013] The advantages of adopting the above technical solution are: by setting a third light-transmitting cavity on the twist cap and setting a light-transmitting protective cover at the third light-transmitting cavity, the light transmission effect is better and dust intrusion can be effectively prevented. At the same time, the twist cap does not need to be made of light-transmitting material, and the structural design is more reasonable.

[0014] Furthermore, the outer peripheral wall of the core seat is provided with snap ring grooves at the upper and lower ends. The snap ring grooves are used to install snap rings. The snap rings limit the core seat to the first outer shell. The snap ring grooves are symmetrically provided with rotating positioning blocks. The snap rings are provided with corresponding rotating positioning cavities. The rotating positioning cavities cooperate with the rotating positioning blocks.

[0015] The advantages of adopting the above technical solution are: by setting a retaining ring groove on the core seat, the retaining ring can be installed to prevent the core seat from falling out, and by cooperating with the rotating positioning cavity and the rotating positioning block, the rotation angle of the core seat can be limited, making the use more reasonable.

[0016] Furthermore, the outer peripheral wall of the retaining ring is symmetrically provided with anti-rotation protrusions, and the inner cavity of the first outer shell is provided with an anti-rotation groove. The lower end of the anti-rotation groove is through-hole, and the anti-rotation protrusions cooperate with the anti-rotation groove.

[0017] The advantages of the above technical solution are: the anti-rotation protrusion and anti-rotation groove can prevent the retaining ring from rotating, making the rotation positioning cavity and the rotation positioning block reliable and the structure design reasonable.

[0018] Furthermore, the contact mechanism includes a first base, a second base, a second contact element, a tension spring, a moving contact element, and two third contact elements. The lower end of the first base has a second mounting cavity that extends through the front and rear and has an opening at the bottom. The second base is inserted into the second mounting cavity. The third contact elements and the second contact elements are arranged side by side on the second base. A hinge frame is rotatably connected between the second base and the second contact element. The tension spring connects the hinge frame and the moving contact element, and one end of the moving contact element is rotatably connected to the second contact element. The inner ends of the third contact elements are respectively located on the up-and-down swing path of the other end of the moving contact element. The first base also has a sliding cavity for installing a sliding push plate. The sliding push plate is used to cooperate with the hinge frame and the core seat. The upper end of the first base also has a third mounting cavity, and the first contact element and the indicator light are cooperated with in the third mounting cavity.

[0019] The advantages of the above technical solution are as follows: During installation, the second base is inserted into the second mounting cavity from the bottom opening side, which can then be connected to the first base. Installation is convenient. When the core base moves down, the core base causes the hinge frame to swing downward through the sliding push plate. When the core base moves up, the sliding push plate stops pressing against the hinge frame. Under the action of the tension spring, the hinge frame will cause the moving contact to swing upward, thereby forming contact with the corresponding third electrical component. The second electrical component can then form two circuits with the two third electrical components. Furthermore, by setting the third mounting cavity and placing the first electrical component and the indicator light in the third mounting cavity, the overall height of the product can be effectively reduced.

[0020] Furthermore, the second base body is composed of a positioning base and a power connector. The positioning base is designed in an L-shape. A first connecting portion is provided on the right side of the horizontal portion of the positioning base, and a second connecting portion is provided on the left side of the power connector. A third connecting portion is provided on both the left and right sides of the second mounting cavity. The first connecting portion and the second connecting portion cooperate with the third connecting portion, respectively. A fourth connecting portion is provided on the upper side of the second mounting cavity. The vertical portion of the positioning base cooperates with the fourth connecting portion. A fifth connecting portion is also provided on the left side of the vertical portion of the positioning base, and a sixth connecting portion is also provided on the right side of the power connector. The fifth connecting portion cooperates with the sixth connecting portion. A seventh connecting portion is also provided on both sides of the first base body. The seventh connecting portion cooperates with the first power connector. The sliding cavity is provided on both the front and rear sides of the first base body.

[0021] The advantages of the above technical solution are as follows: the positioning seat and the power connector can be assembled into a second seat through the cooperation of the fifth and sixth connecting parts. The assembled second seat can be installed into the second mounting cavity through the cooperation of the first, second and third connecting parts, thus forming a connection with the first seat. The positioning seat is set into an L-shaped structure, and the installation of the assembled second seat is more reliable by cooperating the vertical part of the positioning seat with the fourth connecting part. Therefore, the structure of the second seat assembled from the positioning seat and the power connector ensures the reliability of the connection and facilitates production and processing. Furthermore, the design of the position of the fifth connecting part, the structural setting of the first, second and third connecting parts, and the design of the sliding push plate installation position can achieve the purpose of not needing to identify the installation direction. The structural design is reasonable.

[0022] Furthermore, a second outer shell may be connected to the outside of the first outer shell, and the upper end of the second outer shell is provided with a third mounting ring edge, which is used to cooperate with the twist cap.

[0023] The advantages of adopting the above technical solution are: by setting a second shell with a third mounting ring edge outside the first shell, it is possible to match different sizes of twist caps, and the design is more reasonable. Attached Figure Description

Detailed Implementation

[0026] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0027] Please see Figures 1 to 16As shown, a high-transmittance emergency stop switch includes a contact mechanism and an operating mechanism. The operating mechanism is positioned above the contact mechanism and is used to switch the circuit of the contact mechanism. The operating mechanism includes a core base 1 and a toggle cap 2. The toggle cap 2 is connected above the core base 1. An indicator light 3 is also provided above the contact mechanism. First electrical connectors 4 are provided on both sides of the indicator light 3 to supply power to the indicator light 3. A first mounting cavity 5 is radially provided on the core base 1. Elastic retaining elements are provided between the toggle cap 2 and the core base 1 and within the first mounting cavity 5. The positioning component and the elastic positioning component are used to cooperate with the emergency stop locking and rotation reset of the core seat 1. The core seat 1 is also axially provided with a first light-transmitting cavity 6. The first light-transmitting cavity 6 is provided with an axially eccentric second light-transmitting cavity 7. Both the first light-transmitting cavity 6 and the second light-transmitting cavity 7 are used to cooperate with the indicator light 3. The first mounting cavity 5 is radially eccentrically arranged and located on the radial side of the second light-transmitting cavity 7. The first mounting cavity 5 and the second light-transmitting cavity 7 are offset. In the above structure, by providing the first mounting cavity 5 on the core seat 1, and by the space between the torsion cap 2 and the core seat 1, and An elastic positioning component is installed inside the first mounting cavity 5. In use, pressing the toggle cap 2 causes the core seat 1 to move downwards. After the core seat 1 moves into position, the elastic positioning component can put the core seat 1 in the emergency stop locked position. When reset is required, twisting the toggle cap 2 causes the core seat 1 to rotate, and the elastic positioning component can release the emergency stop lock. At the same time, after the core seat 1 rotates into position, the elastic positioning component can also reset the core seat 1 and the toggle cap 2. Furthermore, by setting an axially penetrating first light-transmitting cavity 6 on the core seat 1, and setting an axially eccentric second light-transmitting cavity 7 inside the first light-transmitting cavity 6, and making the first mounting cavity 5 radially eccentrically positioned on the radial side of the second light-transmitting cavity 7, the first mounting cavity 5 and the second light-transmitting cavity 7 are offset. Therefore, the components of the elastic positioning component inside the first mounting cavity 5 will not block the first light-transmitting cavity 6 and the second light-transmitting cavity 7, thus ensuring good light transmission performance. The toggle cap 2 can also be made of light-transmitting material, so as to clearly indicate the position of the emergency stop switch and be better suited for darker environments. The structural design is reasonable.

[0028] In this embodiment, the elastic positioning assembly includes a positioning slide rod 8, a compression spring 9, and a rotary compression spring 10. The compression spring 9 and the positioning slide rod 8 are disposed inwardly and outwardly in the first mounting cavity 5. A ratchet groove 12 is provided in the inner cavity of the first outer shell 11 at a position opposite to the lower part of the first mounting cavity 5. The ratchet groove 12 is used to engage with the positioning slide rod 8. The first outer shell 11 is also provided with a first positioning part 13, and the core seat 1 is provided with a second positioning part 14. The first positioning part 13 and the second positioning part 14 are respectively connected to both ends of the rotary compression spring 10. Both the first positioning part 13 and the second positioning part 14 can be mounting holes. In the above structure, by providing the first positioning part 13 and the second positioning part 14, the rotary compression spring 10 can effectively define its position. During the process of the twist cap 2 driving the core seat 1 to move downward, the rotary compression spring 10 will first compress. After the core seat 1 moves to the lower position, the compression spring 9 causes the positioning slide rod 8 to move out of the first mounting cavity 5 and cooperate with the ratchet 12, thereby completing the emergency stop lock. The ratchet 12 ensures that the twist cap 2 can only rotate in one direction. When it is necessary to release the emergency stop lock, the twist cap 2 is rotated, which in turn drives the core seat 1 to rotate. At this time, the rotary compression spring 10 will generate a rotary reset force. During the process of the twist cap 2 driving the core seat 1 to rotate, the positioning slide rod 8 will move back into the first mounting cavity 5 under the action of the ratchet 12 until it is fully inserted. At this time, the rotary compression spring 10 releases the rotary reset force and the compression reset force, thereby driving the twist cap 2 and the core seat to rotate upward and reset.

[0029] In this embodiment, the upper end of the first housing 11 is provided with a first mounting ring 15 and a second mounting ring 16. The rotary compression spring 10 is disposed between the first mounting ring 15 and the second mounting ring 16. The first mounting ring 15 is also used to cooperate with the positioning slide rod 8, and the second mounting ring 16 is also used to cooperate with the torsion cap 2. In the above structure, by setting the first mounting ring 15 and the second mounting ring 16, a good position limit is formed for the rotary compression spring 10, and the use effect of the rotary compression spring 10 is better. The first mounting ring 15 also enables the positioning slide rod 8 to be stably disposed at the first mounting cavity 5, and the second mounting ring 16 enables the installation and use of the torsion cap 2 to be more reliable. The overall structural design is reasonable.

[0030] In this embodiment, a sealing ring groove 17 is provided on the outer peripheral wall of the core seat 1. The sealing ring groove 17 is positioned above the first mounting cavity 5. A sealing element 18 is provided inside the sealing ring groove 17. In the above structure, the cooperation between the sealing ring groove 17 and the sealing element 18 can effectively prevent the intrusion of dust, making it safer to use and with a reasonable structural design.

[0031] In this embodiment, the twist cap 2 is provided with a third light-transmitting cavity 19, which cooperates with the first light-transmitting cavity 6 and the second light-transmitting cavity 7. A light-transmitting protective cover 20 is provided at the third light-transmitting cavity 19, and the light-transmitting protective cover 20 is snapped into the third light-transmitting cavity 19. In the above structure, by providing a third light-transmitting cavity 19 on the twist cap 2 and providing a light-transmitting protective cover 20 at the third light-transmitting cavity 19, the light transmission effect is better, and dust intrusion can be effectively prevented. At the same time, the twist cap 2 does not need to be made of light-transmitting material, and the structural design is more reasonable.

[0032] In this embodiment, a snap-fit ​​groove 21 is provided at the upper and lower ends of the outer peripheral wall of the core seat 1. The snap-fit ​​groove 21 is used to install a snap ring 22. The snap ring 22 restricts the core seat 1 to the first outer shell 11. A rotating positioning block 23 is symmetrically provided in the snap-fit ​​groove 21. A corresponding rotating positioning cavity 24 is provided on the snap ring 22. The rotating positioning cavity 24 cooperates with the rotating positioning block 23. In the above structure, by providing a snap-fit ​​groove 21 on the core seat 1, the purpose of installing the snap ring 22 is achieved, preventing the core seat 1 from falling out. And by cooperating with the rotating positioning cavity 24 and the rotating positioning block 23, the purpose of limiting the rotation angle of the core seat 1 can be achieved, making the use more reasonable.

[0033] In this embodiment, anti-rotation protrusions 25 are symmetrically provided on the outer peripheral wall of the retaining ring 22, and an anti-rotation groove 26 is provided in the inner cavity of the first outer shell 11. The lower end of the anti-rotation groove 26 is through-hole. The anti-rotation protrusions 25 and the anti-rotation groove 26 cooperate with each other. In the above structure, the cooperation between the anti-rotation protrusions 25 and the anti-rotation groove 26 can prevent the retaining ring 22 from rotating, so that the cooperation between the rotation positioning cavity 24 and the rotation positioning block 23 is reliable and the structural design is reasonable. It should be noted that the installation direction of the core seat 1 is from bottom to top. Therefore, the cooperation between the anti-rotation protrusions 25 and the anti-rotation groove 26, and the cooperation between the rotation positioning cavity 24 and the rotation positioning block 23 can reliably limit the position of the core seat 1.

The hinge frame 34 and the movable contact 31 are provided, with one end of the movable contact 31 rotatably connected to the second electrical contact 29. The inner ends of the two third electrical contacts 32 are respectively located on the up-and-down swing path of the other end of the movable contact 31. More specifically, in the initial state, the other end of the movable contact 31 will form a circuit connection with the third electrical contact 32 whose inner end is on the upper side. The first base 27 is also provided with a sliding cavity 35, which is used to install a sliding push plate 36. The sliding push plate 36 is used to cooperate with the hinge frame 34 and the core base 1. The sliding push plate 36 moves downward, pushing the hinge frame 34 and causing the moving contact 31 to swing downward. A third mounting cavity 37 is also provided at the upper end of the first base 27. The first electrical connector 4 and the indicator light 3 are fitted into the third mounting cavity 37. In this structure, during installation, the second base 28 is inserted into the second mounting cavity 33 from the bottom opening side, thus connecting to the first base 27. Installation is convenient. Furthermore, when the core base 1 moves downward, the sliding push plate 36 causes the hinge frame to... When the movable contact 31 swings downward, and the core seat 1 moves upward, the sliding push plate 36 stops pressing against the hinge frame 34. Under the action of the tension spring 30, the hinge frame 34 will drive the movable contact 31 to swing upward, thereby forming contact with the corresponding third electrical contact 32. The second electrical contact 29 can then form two circuits with the two third electrical contacts 32. Furthermore, by setting the third mounting cavity 37 and setting the first electrical contact 4 and the indicator light 3 to cooperate at the third mounting cavity 37, the overall height of the product can be effectively reduced.

[0035] In this embodiment, the second seat 28 is composed of a positioning seat 38 and a power connector 39.

It should be noted that the third connecting portion 42 can... The first slot is a through slot running from front to back. The fourth connecting part 43 can be a second through slot running from front to back, with the second slot positioned at the center. Both the first connecting part 40 and the second connecting part 41 can be corresponding first inserts. The first connecting part 40 can cooperate with either the third connecting part 42 on the left or the third connecting part 42 on the right. Similarly, the second connecting part 41 can also cooperate with the third connecting part 42 on the right. The sliding push plate 36 can be installed and cooperated with either the sliding cavity 35 on the front or the sliding cavity 35 on the rear. The installation position of the sliding push plate 36 is determined according to the installation direction of the positioning seat 38, thereby achieving the purpose of not needing to identify the installation direction. A fifth connecting part 44 is also provided on the upper left side of the vertical part of the positioning seat 38, and a power connector 39 is also provided. A sixth connecting part 45 is also provided on the right side. The fifth connecting part 44 cooperates with the sixth connecting part 45. Two fifth connecting parts 44 and two sixth connecting parts 45 can be provided. The two fifth connecting parts 44 can be the third slot and the second post, respectively.

The first connecting part 40, the second connecting part 41 and the third connecting part 45 can be used to assemble the second base 28. With the cooperation of 42, the assembled second base 28 can be installed into the second mounting cavity 33, thereby forming a connection with the first base 27. The positioning seat 38 is set into an L-shaped structure, and the cooperation between the vertical part of the positioning seat 38 and the fourth connecting part 43 makes the installation of the assembled second base 28 more reliable. Therefore, the second base 28 adopts the structure of the positioning seat 38 and the power connection seat 39, which not only ensures the reliability of the connection, but also facilitates production and processing. Furthermore, through the design of the position of the fifth connecting part 44, the structural setting of the first connecting part 40, the second connecting part 41 and the third connecting part 42, and the design of the installation position of the sliding push plate 36, the purpose of not needing to identify the installation direction can be achieved, and the structural design is reasonable.

[0036] In this embodiment, a second outer shell 47 can also be connected to the outside of the first outer shell 11.
