Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 13, the conductive switch of the present invention includes a housing 1, wherein the housing 1 has a rotating shaft 2 therein, two ends of the rotating shaft 2 extend through the housing 1 to the outside, one end of the rotating shaft 2 has an opening member 3, and the other end has a locking member 4. The rotating shaft 2 has a conductive member 5 in the middle, the opening member 3 and the locking member 4 are located outside the housing 1, and the conductive member 5 is located inside the housing 1. The conducting component 5 is used for leading in an external power supply so that the circuit is communicated, the conducting component 5 is provided with two positions, one position is connected with a live wire, the other position is communicated with a zero wire, and certainly, if the three-phase power is provided, one conducting component 5 can be additionally arranged. And the opening assembly 3 is used to pull the locking assembly 4 such that the elastic member 22 in the locking assembly 4 is compressed, thereby putting the locking assembly 4 in place.
The first annular groove 10 has rotationally symmetrically arranged lifting blocks 17 around both ends, and the bottom surface of the lifting member 7 has grooves 18 matching with the lifting blocks 17. One end of the lift block 17 is gradually raised from the plane of the restriction plate 6 toward the other end.
When the driving element 9 is rotated, the lower recess 18 is stopped by the lifting block 17, and the pushing part 16 can gradually rise from the pushing groove 12 to the sliding surface 14 along with the guide surface 13, and then is stopped by the stopping part 15. When the driving member 9 is rotated reversely, because the distance between the rotating member 8 and the limiting plate 6 is constant, when the driving member 9 is rotated reversely, the groove 18 does not separate from the lifting block 17 first, but the pushing portion 16 slides from the sliding surface 14 first, then slides into the pushing groove 12 along with the guide surface 13, and is blocked by the blocking surface 20 finally, when the handle 19 is rotated again, the lifting block 17 separates from the groove 18, and because of the height difference between the pushing groove 12 and the sliding surface 14, the lifting member 7 can be driven to rotate continuously without being influenced by the lifting block 17 when the driving member 9 is rotated continuously.
The locking assembly 4 includes a toothed plate 21, a resilient member 22, a restraint member 23, and a nut 24. The toothed plate 21 is installed on the outer wall of the housing 1, and the toothed plate 21 has a second annular groove 25 in the middle thereof, and the rotary shaft 2 is seated in the second annular groove 25. The toothed plate 21 further has a first tooth portion 26 and a sliding portion 27, the second annular groove 25 is located in the middle of the sliding portion 27, and the first tooth portion 26 is located on two sides of the sliding portion 27. The limiting piece 23 is mounted on the tooth plate 21, a through groove 28 for placing the elastic piece 22 is formed in the middle of the limiting piece 23, the elastic piece 22 is located between the tooth plate 21 and the limiting piece 23, and second tooth parts 29 matched with the first tooth parts 26 are formed on two sides of the through groove 28. The limiting member 23 is also provided with a threaded sleeve 30, and the nut 24 is mounted on the threaded sleeve 30.
The rotating shaft 2 has a restriction ring 31 thereon, and the second annular groove 25 has a restriction groove 32 therein, the restriction ring 31 being disposed in the restriction groove 32. The restricting groove 32 and the restricting ring 31 restrict the rotary shaft 2 so that the rotary shaft 2 cannot move in the axial direction when the driven member 9 is rotated. The limiting member 23 has a guide hole 33 in the middle thereof, which is communicated with the threaded sleeve 30 and the through slot 28, a guide arc slot 34 is formed on the inner wall of the guide hole 33, and a spherical protrusion 35 is formed on the rotating shaft 2 and is disposed in the guide arc slot 34. The spherical protrusion 35 is adapted to move along the arc shape in the guide arc groove 34, thereby changing the position of the restricting member 23. When the position of the restricting member 23 is changed, the elastic member 22 can be compressed or restored to a natural state.
The elastic member 22 has a flat surface portion 36, an elastic arm 37, and a restricting arm 38, and the elastic arm 37 is located at both ends of the restricting arm 38. The spring arm 37 has an arc-shaped portion 39, the arc-shaped portion 39 is disposed on the sliding portion 27, the restricting arm 38 has a bent portion 40, and the restricting member 23 has a vertical groove 41 in which the bent portion 40 is disposed.
When the pushing part 16 is located on the sliding surface 14, the spherical protrusion 35 is located at the end of the arc guiding groove 34, the end is close to one end of the elastic element 22, and the elastic element 22 is compressed, because the arc guiding groove 34 has a certain distance, when the pushing part 16 is placed in the pushing groove 12 and rotates, the spherical protrusion 35 can move from the end to the front end of the arc guiding groove 34, so that the spherical protrusion 35 changes the distance between the limiting member 23 and the tooth plate 21, and the elastic element 22 recovers to the natural state, that is, the distance between the limiting member 23 and the tooth plate 21 is lengthened. At this time, the second tooth portion 29 is also disengaged from the first tooth portion 26, and the rotary shaft 2 can be moved upward, and the arc portion 39 can be moved on the slide portion 27.
The movement of the restricting member 23 is caused by the movement of the spherical protrusions 35 in the guide arc grooves 34, and since the rotating shaft 2 is restricted by the restricting ring 31 in the restricting grooves 32 in the second annular groove 25, when the rotating shaft 2 is rotated, the spherical protrusions 35 can be caused to drive the restricting member 23 to move back and forth, so as to change the distance between the restricting member 23 and the tooth plate 21, and thus, whether the elastic member 22 is in the compressed state or the natural state can be determined.
While the nut 24 is fixed to the restricting member 23 and does not rotate with the rotary shaft 2.
The housing 1 has third annular grooves 42 on both sides thereof, which engage with the first and second annular grooves 10 and 25. The rotary shaft 2 is disposed in the first, second, and third annular grooves 10, 25, and 42 to be slidable up and down therein.
When the conductive switch is in an environment where an accident occurs due to the fact that the conductive switch is in a state of being powered off by mistake, the housing 1 can be transversely installed, that is, the first annular groove 10, the second annular groove 25 and the third annular groove 42 are in a transverse direction rather than a vertical direction. When the conductive switch is in an environment where an accident occurs due to the fact that the conductive switch is touched by mistake and the switch is powered on, the first annular groove 10, the second annular groove 25 and the third annular groove 42 only need to be vertically installed. And the transversely arranged first annular groove 10, second annular groove 25 and third annular groove 42 can prevent the rotating shaft 2 from falling or rolling to the other end when being touched by mistake, so that the safety of the circuit is ensured.
The conductive assembly 5 includes a contact piece 43 and a mounting piece 44, the contact piece 43 is mounted inside the housing 1, the mounting piece 44 is mounted on the rotating shaft 2, the mounting piece 44 has a mounting portion 45, the mounting portion 45 has a first conductive piece 46 and a second conductive piece 47, and the mounting portion 45, the first conductive piece 46 and the second conductive piece 47 are connected by a pin 48. The mounting member 44 is made of an insulating material.
The two contact pads 43 are connected to an external power source, and the positive and negative poles of the device are mounted between the first conductive pad 46 and the second conductive pad 47. When the rotating shaft 2 moves to the upper ends of the first annular groove 10, the second annular groove 25 and the third annular groove 42, the second conductive plate 47 then moves toward the opening assembly 3, so that the contact piece 43 contacts with the second conductive plate 47, and the lower end of the contact piece 43 is deformed, thereby facilitating the communication of the circuit. The contact piece 43 is arranged right above the second conducting plate 47, and deformation of the lower end of the contact piece 43 is facilitated during contact.
When it is necessary to complete the electric circuit, the driving member 9 is rotated so that the pushing portion 16 moves from the sliding surface 14 into the pushing groove 12, then the driving member 9 is continuously rotated so that the elastic member 22 returns to a natural state, the second tooth portion 29 is disengaged from the first tooth portion 26, then the driving member 9 and the nut 24 are simultaneously lifted so that the rotating shaft 2 reaches the upper ends of the first annular groove 10, the second annular groove 25 and the third annular groove 42, and then the driving member 9 is reversely rotated so that the elastic member 22 is compressed, the second tooth portion 29 engages with the first tooth portion 26, so that the rotating shaft 2 is fixed at the upper end, and since the distance from the driving member 9 to the restricting plate 6 is constant, the lifting member 7 can be restricted. So that the second conductive plate 47 contacts the lower end of the contact piece 43 to connect the circuit.
When the pushing portion 16 is erroneously touched to the pushing groove 12, the rotating shaft 2 is not rotated at this time, and the rotating shaft 2 can be rotated only when the rotation is continued. When the rotation is to be continued, the rotation shaft 2 is rotated to move the restricting member 23 by a force required to disengage the lifting block 17 from the recess 18. The conductive switch has two limits, and can prevent the circuit from being connected or disconnected due to mistaken touch.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
