Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 6, in the embodiment of the present invention, a voltage sensor 100 based on a tamper-proof function includes: voltage sensor body 10, closure cap 20, built-in latch mechanism 30, fixing bolt 40 and terminal 50. Terminals 50 are provided at both sides of the upper end of the voltage sensor body 10, and the terminals 50 are used to make the voltage sensor body 10 abut against the connection lead 200 of the relevant device. Fixing bolts 40 are provided at both sides of the lower end of the voltage sensor main body 10, and the fixing bolts 40 are used to fixedly connect the voltage sensor main body 10 with the device mounting plate 300. The closing cap 20 is attached to the outside of the voltage sensor body 10 by the built-in latch mechanism 30, the closing cap 20 is used to close and cover the voltage sensor body 10, and the connection lead 200 connected to the voltage sensor body 10 passes through the closing cap 20.
The built-in latch mechanism 30 includes: the device comprises a convex column 31, a clamping groove 32, a U-shaped connecting frame 33, a sliding clamping block 34 and a first connecting spring 35. The convex column 31 is vertically and fixedly connected to the upper end of the fixing bolt 40. The slot 32 is opened at the lower side wall of the convex column 31. The U-shaped connection frame 33 is horizontally and fixedly connected to the lower end inner wall of the closing cap 20. The sliding fixture block 34 is horizontally inserted at the tail end of the U-shaped connecting frame 33 in a sliding mode, and the lower side wall of the end head of the sliding fixture block 34 close to the center of the closing cover 20 is a smooth arc surface. The first connecting spring 35 is sleeved at the end of the sliding block 34 close to the inner wall of the closing cover 20, and the first connecting spring 35 is connected between the sliding block 34 and the U-shaped connecting frame 33.
When the closing cap 20 is covered to the position where the voltage sensor body 10 is installed, the sliding latch 34 is aligned with the boss 31 up and down. When the closing cap 20 is pressed from top to bottom, the sliding block 34 is pressed to the upper end of the protruding column 31 by the smooth arc surface. Due to the existence of the smooth arc surface, the sliding clamping block 34 is transversely moved when being extruded, and the first connecting spring 35 is stretched to generate resilience force in the process. And the end of the sliding block 34 slides down along the side wall of the convex column 31 after traversing. When the end of the sliding latch 34 is aligned with the position of the engaging groove 32, the sliding latch 34 is inserted into the engaging groove 32 under the resilient force of the first connecting spring 35, so that the sealing cap 20 is fixedly mounted on the position of the voltage sensor body 10. Since the built-in latch mechanism 30 is located inside the closure cap 20 and cannot be opened from the outside, it is ensured that the wiring of the voltage sensor main body 10 before acceptance is tampered with.
The tamper-resistant function-based voltage sensor 100 further includes: and a wire body fixing mechanism 60. The wire body fixing mechanism 60 includes: the device comprises a first strip-shaped sliding groove 61, a second strip-shaped sliding groove 62, a sliding cross column 63, a limiting clamping plate 64, a second connecting spring 65, a supporting frame 66, a linkage rotating rod 67 and an ejection mechanism 68. The first bar-shaped chute 61 opens horizontally at the inner top of the closure 20. The limit clamp plate 64 is vertically and slidably connected to the first strip-shaped sliding groove 61. The second strip-shaped sliding groove 62 is vertically formed in the front and rear inner walls of the closing cover 20. The sliding horizontal column 63 is horizontally connected to the second strip-shaped sliding groove 62 in a sliding manner. The second connecting spring 65 is connected between the inner wall of the first linear guide groove 61 and the stopper bridge 64. The support bracket 66 is fixedly attached at the outer wall of the voltage sensor body 10. The linkage rotating rod 67 is rotatably connected to the end of the supporting frame 66 through a rotating shaft, and the upper end of the linkage rotating rod 67 is attached to the outer wall of the limit clamp plate 64. The ejector mechanism 68 is provided on the lower side of the interlocking turn bar 67.
The ejector mechanism 68 includes: a threaded connecting block 681, a threaded push rod 682, a stem 683, a linkage block 684, a first telescoping connecting rod 685, and a third connecting spring 686. The screw-threaded connecting blocks 681 are fixedly connected to the left and right inner walls of the closing cap 20. The threaded push rod 682 is vertically threaded through the threaded connection block 681, and the threaded push rod 682 is aligned with the sliding cross column 63. The linkage block 684 is connected to the underside of the support bracket 66 by a first telescoping connecting rod 685. The rotary handle 683 is fixedly connected to the lower end of the threaded push rod 682, and the head of the linkage block 684 is positioned on the upper side of the rotary handle 683, while the lower head of the linkage rotary rod 67 obliquely butts against the upper side of the linkage block 684. The third linking spring 686 is sleeved on the first telescopic linking rod 685, and both ends of the third linking spring 686 are fixedly connected to a fixed end and a telescopic end of the first telescopic linking rod 685, respectively.
When the connecting lead 200 passes through the corresponding position of the closing cover 10, so that the connecting lead 200 is horizontally arranged on the upper side of the sliding horizontal column 63, and the connecting lead 200 is connected with the terminal 50 of the voltage sensor main body 10, the threaded mandril 682 is rotated by the rotating handle 683, so that the threaded mandril 682 pushes the sliding horizontal column 63 upwards, and the sliding horizontal column 63 slides upwards along the second strip-shaped sliding groove 62. Sliding cross-post 63 compresses connecting wires 200 between stop clip 64 and the side wall of closure 20. And the knob 683 pushes against the linkage block 684 after the knob 683 moves up to the corresponding position. The linkage block 684 is lifted by means of the first telescopic connecting rod 685 to squeeze the lower end of the linkage rotating rod 67, and the upper end of the linkage rotating rod 67 pushes the limit clamp plate 64 to make it slide along the first linear sliding groove 61 to squeeze the connecting wire 200 on the sliding cross column 63. This allows the portion of connecting lead 200 adjacent to terminal 50 to be securely clamped to prevent the outer portion of connecting lead 200 from being pulled to interfere with the connection of terminal 50.
The end face of the limiting clamping plate 6 close to the sliding cross column 63 is provided with anti-slip threads for increasing friction force.
The tamper-resistant function-based voltage sensor 100 further includes: the sending mechanism 70 is positioned. The positioning transmission mechanism 70 includes: the device comprises a mounting box 71, a small electric telescopic rod 72, a top cover 73, a GPS (global positioning system) positioner 74, a power supply 75 for supplying power, a background monitoring terminal 76, a signal lamp 77 and a trigger mechanism 78. The mounting box 71 is fixedly attached to the top outer side of the closing cap 20. The small electric telescopic rods 72 are vertically and fixedly connected to the inner side of the mounting box 71 in a left-right pair. The top cover 73 is horizontally and fixedly connected to the upper end of the small electric telescopic rod 72, and the top cover 73 is closely attached to the upper side of the mounting box 71. A GPS locator 74 is fixedly mounted to the underside of the top cover 73. A power source 75 is mounted to the inside of the small power telescopic pole 72, the power source 75 supplying power to the small power telescopic pole 72 and the GPS locator 74. The signal lamp 77 is provided with a plurality of distributed background monitoring terminals 76. Each GPS locator 74 is provided with an independent number and each signal lamp 77 is provided with a corresponding number. The GPS locator 74 and the signal lamp 77 of the same independent number are wirelessly connected through the rear set monitoring terminal 76. A trigger mechanism 78 is provided on the outer wall of the closure cap 20, the trigger mechanism 78 being for triggering the GPS locator 74.
The trigger mechanism 78 includes: a baffle 781, a second telescopic connection rod 782, a fourth connection spring 783, a pressure sensing switch 784, and a support ceramic body 785. The baffle plates 781 are distributed at the respective outer walls of the closing cap 20. A second telescopic link 782 is connected between the baffle 781 and the outer wall of the closure cap 20. The fourth connection spring 783 is sleeved at the second telescopic connection rod 782, and the fourth connection spring 783 is in a stretched state.

A support ceramic body 785 is connected between the baffle plate 781 and the closing cap 20.
When there is an outside person who hammers the closing cap 20 to break the closing cap 20, the supporting ceramic body 785 between the baffle plate 781 and the closing cap 20 is broken once the baffle plate 781 is struck. Then the baffle plate 781 slides and hits the closing cap 20 by means of the second telescopic link 782 under the resilient force of the fourth link spring 783, so that the pressure sensing switch 784 senses. The pressure sensitive switch 784 triggers the GPS locator 74. The GPS locator 74 transmits a position signal, and the background monitor terminal 76 receives the signal, and then causes a signal lamp 77 of the same number as the GPS locator 74 to be activated. The relevant background staff will then rely on the lighted signal lamp 77 to go to the corresponding location for inspection.
The trigger mechanism 78 further includes: an elastic rubber striker 786 for protecting the pressure sensitive switch 784. An elastic rubber striker 786 is fixedly attached to the bezel 781 and the elastic rubber striker 786 is present in alignment with the pressure sensitive switch 784. The elastic rubber striker 786 prevents the baffle 781 from directly striking the pressure sensitive switch 784 and causing damage.
The mounting case 71 is integrally cast with the closing lid 20.
The mounting box 71 is a square.
The lower end face of the closing cap 20 completely coincides with the upper end opening of the mounting box 71.
