Description

Technical Field

[0001] The present invention relates to the technical field of electricity meter detection, and particularly to a portable electricity meter detection device. Background Art

[0002] With the continuous development of the power system, the electricity meter, as an important metering device in the power system, its accuracy is crucial for power companies and users. Therefore, it is essential to regularly detect and calibrate the electricity meter. However, traditional electricity meter detection methods usually rely on manual operation, which is not only inefficient but also prone to human errors.

[0003] In the prior art, most electricity meter detection devices require manual loosening and then tightening of screws one by one to fix the plug heads of the detection device in the wiring holes of the electricity meter. This method is not only time-consuming and laborious but also particularly inconvenient when dealing with multiple electricity meters of the same specification.

[0004] In addition, for electricity meters of different models and specifications, the positions of the screws and the layout of the wiring holes may vary, which requires the detection device to have a certain degree of versatility and adaptability to be able to quickly and accurately complete the detection work of different electricity meters.

[0005] Therefore, a portable electricity meter detection device is needed to solve the above problems. Summary of the Invention

[0006] To solve the above problems, that is, to solve the problem of cumbersome operation of the existing detection equipment when detecting an electricity meter, the present invention provides a portable electricity meter detection device.

[0007] A portable electricity meter detection device includes an electricity meter, a slotted screw and a wiring hole on the electricity meter, and further includes a first sliding frame. A clamping mechanism is slidably installed on the first sliding frame. A second sliding frame is installed on the front surface of the first sliding frame through a first telescopic mechanism. A plurality of screwing mechanisms are slidably installed on the second sliding frame. A driving mechanism is further provided on the second sliding frame. The screwing mechanism is drivingly connected to the driving mechanism. A wiring mechanism is installed on the front surface of the screwing mechanism through a second telescopic mechanism. A plug head is installed at the bottom end of the wiring mechanism. A control box is provided on the first sliding frame. The plug head is electrically connected to the control box.

[0008] Preferably, the top view of the first sliding frame is in a square shape. The clamping mechanism includes a first screw rod cavity and a second screw rod cavity. The first screw rod cavities are respectively formed at positions near one end on the front and back sides inside the first sliding frame. The second screw rod cavities are respectively formed at positions near the other end on the front and back sides inside the first sliding frame. First screws are coaxially and rotatably installed inside the two first screw rod cavities respectively. Second screws are coaxially and rotatably installed inside the two second screw rod cavities respectively. The first screw and the second screw within the same frame wall of the first sliding frame are coaxially and fixedly connected by a coaxial rod. The thread directions of the first screw and the second screw within the same frame wall of the first sliding frame are opposite. A first rotating shaft is rotatably installed on one side of the first sliding frame. The inner end of the first rotating shaft extends into the first sliding frame and is coaxially and fixedly installed with a fourth gear. One ends of the two first screws close to the first rotating shaft are coaxially and fixedly installed with fifth gears respectively. The two fifth gears are in transmission connection with the fourth gear through a second toothed belt. Two sliding rings are slidably installed on the front frame and the back frame of the first sliding frame respectively. A clamping plate is fixedly installed on the outer side of the bottom of the sliding ring. The two sliding rings are symmetric about the middle of the first sliding frame. The two sliding rings are respectively located outside the first screw rod cavity and the second screw rod cavity. An extension plate is fixedly installed on the inner side of the sliding ring. A screw ring is fixedly installed at the inner end of the extension plate. The screw rings on the inner sides of the two sliding rings are respectively in threaded connection with the first screw and the second screw. By symmetrically and slidably installing sliding rings on the first sliding frame and making the thread directions of the first screw and the second screw driving the symmetric sliding rings opposite, when it is necessary to detect the electricity meter, only by rotating the first rotating shaft, the symmetric sliding rings can be driven to slide towards or away from each other simultaneously, which not only facilitates fixing the device on the electricity meter to enhance the stability of the device during detection, but also enables the wiring holes to be located in the middle position of the device, facilitating connection with the plug head.

[0009] Preferably, the first telescopic mechanism includes a first telescopic tube. One end of the first telescopic tube is fixedly installed at the middle position on the front side of the first sliding frame. A first telescopic rod is slidably installed inside the first telescopic tube through a third spring. The end of the first telescopic rod away from the first sliding frame extends out of the first telescopic tube and is fixedly connected to the middle position on the back side of the second sliding frame. A third inclined tooth groove is formed on the upper surface of the first telescopic rod. A third inclined tooth plate is slidably installed through the top wall of the first telescopic tube at the end away from the first sliding frame. The bottom end of the third inclined tooth plate abuts against the third inclined tooth groove. When the first telescopic rod is pulled outwards, the position of the screwing mechanism can be adjusted to be directly above the slotted screw. The third inclined tooth groove and the third inclined tooth plate not only do not prevent the first telescopic rod from sliding outwards, but also block the retraction of the first telescopic rod. When it is necessary to reset the first telescopic rod, only by pulling the third inclined tooth plate upwards can it be achieved.

[0010] Preferably, the screwing mechanism includes a sliding seat, and erection slide plates are fixedly installed on the front and back of the sliding seat. Erection chutes are formed on the front and back inside the second sliding frame, and the erection slide plates slide in the erection chutes. An inner rotating shaft is vertically and rotatably installed through the interior of the sliding seat, and an expanding diameter ring is coaxially and fixedly installed on the outer surface of the inner rotating shaft. The expanding diameter ring rotates inside the sliding seat.

[0011] Preferably, a vertical sliding rod is vertically and slidably installed through the interior of the inner rotating shaft. A matching hole with a square top view is formed at the bottom end of the vertical sliding rod. A cross head is slidably installed in the matching hole through a fifth spring. Retraction grooves are formed on both sides of the vertical sliding rod, and retraction holes are formed inside the retraction grooves. A retraction block is slidably installed in the retraction hole through a second spring. A first bevel gear plate and a second bevel gear plate are respectively slidably installed in the two retraction grooves. The inner sides of the first bevel gear plate and the second bevel gear plate are fixedly connected to the retraction block. The beveled surfaces of the first bevel gear plate and the second bevel gear plate are opposite. First bevel gear grooves and second bevel gear grooves matching the first bevel gear plate and the second bevel gear plate are formed inside the inner rotating shaft. The first bevel gear plate and the second bevel gear plate respectively abut against the first bevel gear groove and the second bevel gear groove.

[0012] Preferably, a pressing rod is vertically slidably installed in the vertical sliding rod. The top end of the pressing rod extends above the vertical sliding rod. The retraction groove communicates with the pressing rod through a threading hole. The inner sides of the first bevel gear plate and the second bevel gear plate are respectively connected to the pressing rod through a pull rope. The pull rope is arranged through the threading hole. A third gear is coaxially and fixedly installed at a position near the top end of the outer part of the inner rotating shaft; by slidably installing a plurality of screwing mechanisms in the second sliding frame, the device can be applied to cross-head screws with various pitches. By arranging the first bevel gear plate and the second bevel gear plate with opposite bevel surfaces on the vertical sliding rod and arranging the first bevel gear groove and the second bevel gear groove matching the first bevel gear plate and the second bevel gear plate on the inner rotating shaft, the vertical sliding rod cannot slide up and down on the inner rotating shaft by itself. By slidably arranging a pressing rod connected to the first bevel gear plate and the second bevel gear plate in the vertical sliding rod, just hold the vertical sliding rod and then press down the pressing rod to make the first bevel gear plate and the second bevel gear plate disengage from the first bevel gear groove and the second bevel gear groove, and then the up and down sliding of the vertical sliding rod can be controlled, which is convenient to control. The cross head is arranged to be slidable up and down to match the height of the cross-head screw rising or falling during rotation.

[0013] Preferably, the driving mechanism includes a first gear. Both ends of the upper surface of the second sliding frame are rotatably installed with the first gear. The first gear is in the same straight line as a plurality of the third gears. A gear seat is fixedly installed at the middle position of the front surface of the second sliding frame. A second sliding groove is formed at the top of the gear seat. A gear shaft is slidably installed inside the second sliding groove. A pressing arc plate is slidably installed on one side of the second sliding groove close to the second sliding frame through a fourth spring. The pressing arc plate presses against the side of the gear shaft. A second gear is fixedly installed at the top end of the gear shaft. A second rotating shaft is fixedly installed at the top end of the second gear. The two first gears, one second gear and a plurality of the third gears are connected by a first toothed belt for transmission.

[0014] Preferably, inner push rods are fixedly installed at both ends of the upper surface of the sliding seat. Both inner push rods press against the outside of the first toothed belt. A first sliding groove is formed on the upper surface of the sliding seat. The first sliding groove is located at the side of the inner rotating shaft. An outer push rod is slidably installed inside the first sliding groove. The outer push rod is located inside the first toothed belt. The outside of the outer push rod is connected to the outside of the first sliding groove through a first spring. A limiting sliding groove is formed at the side of the first sliding groove. A limiting sliding plate is fixedly installed at the side of the outer push rod. The limiting sliding plate slides inside the limiting sliding groove. A transverse push rod is fixedly installed inside the outer push rod. The other end of the transverse push rod penetrates through the sliding seat and extends to the outside of the sliding seat; by setting the inner push rods to press against the outside of the first toothed belt, the first toothed belt can be in full contact with the third gear, so that when the operator rotates the second gear, it can be ensured that the third gear is rotated through the first toothed belt, thereby driving a plurality of vertical sliding rods simultaneously, enabling the device to loosen or tighten a plurality of flat head screws at the same time, improving the working efficiency. By setting the outer push rod, when it is necessary to slide a certain sliding seat, only need to press the transverse push rod to make the outer push rod press against the inside of the first toothed belt, so that the first toothed belt is separated from the third gear, which can prevent a rotating vertical sliding rod from driving other vertical sliding rods with adjusted positions and heights to rotate, thus damaging the flat head screws.

[0015] Preferably, the second telescopic mechanism includes a second telescopic tube. The second telescopic tube is fixedly installed on the front surface of each sliding seat. A second telescopic rod is slidably installed inside the second telescopic tube through a sixth spring. The end of the second telescopic rod away from the sliding seat extends to the outside of the second telescopic tube and is fixedly installed with a third sliding frame.

[0016] Preferably, the wiring mechanism includes a lifting slide rod. The lifting slide rod is vertically and slidably installed through each of the third sliding frames. A through ring is fixedly installed at the top end of the lifting slide rod. A plurality of the through rings are connected by a series rod penetrating through the interior. The plug head is fixedly installed at the bottom end of the lifting slide rod on the side close to the second sliding frame. By providing the second telescopic rod that can slide horizontally and the lifting slide rod that can slide vertically, not only can the applicable range of the device be improved, but also the convenience of connecting the plug head of the device to the wiring hole can be improved. Among them, the series rod enables the staff to control a plurality of lifting slide rods simultaneously, effectively improving the working efficiency.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, by symmetrically and slidably installing sliding rings on the first sliding frame and making the thread directions of the first screw rod and the second screw rod driving the symmetric sliding rings opposite, when it is necessary to detect the electricity meter, only by rotating the first rotating shaft, the symmetric sliding rings can be driven to slide towards or away from each other simultaneously, which not only facilitates fixing the device on the electricity meter to enhance the stability of the device during detection, but also enables the wiring hole to be located in the middle position of the device, facilitating connection with the plug head.

[0019] 2. In the present invention, by slidably installing a plurality of screwing mechanisms in the second sliding frame, the device can be applicable to flat head screws with various pitches. By providing a first bevel gear plate and a second bevel gear plate with opposite slopes on the vertical slide rod and providing a first bevel gear groove and a second bevel gear groove matching the first bevel gear plate and the second bevel gear plate on the inner rotating shaft, the vertical slide rod cannot slide up and down on the inner rotating shaft by itself. By slidably installing a pressing rod connected to the first bevel gear plate and the second bevel gear plate in the vertical slide rod, only by pinching the vertical slide rod and then pressing down the pressing rod to separate the first bevel gear plate and the second bevel gear plate from the first bevel gear groove and the second bevel gear groove, the vertical slide rod can be controlled to slide up and down, which is convenient for control.

[0020] 3. In the present invention, by providing an inner push rod to abut against the outer side of the first toothed belt, the first toothed belt can be in full contact with the third gear, enabling the operator to ensure that the third gear is rotated through the first toothed belt when rotating the second gear, thereby driving a plurality of vertical slide rods simultaneously, enabling the device to loosen or tighten a plurality of flat head screws at the same time, improving the working efficiency. By providing an outer push rod, when it is necessary to slide a certain slide seat, only by pressing the horizontal push rod to make the outer push rod abut against the inner side of the first toothed belt, the first toothed belt can be separated from the third gear, which can prevent a rotating vertical slide rod from driving other vertical slide rods with adjusted positions and heights to rotate, thus damaging the flat head screws.

[0021] 4. By providing a second telescopic rod that can slide horizontally and a lifting slide rod that can slide vertically, the present invention not only expands the applicable range of the device but also enhances the convenience of connecting the plug head of the device to the wiring hole. Among them, the series rod enables the staff to control multiple lifting slide rods simultaneously, effectively improving the lifting work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1 and Figure 11 As shown, an embodiment of the present invention discloses a portable electric energy meter detection device, including an electric energy meter 1 and a slotted screw 2 and a wiring hole 3 on the electric energy meter 1, and also includes a first sliding frame 4, a clamping mechanism is slidably installed on the first sliding frame 4, a second sliding frame 5 is installed on the front of the first sliding frame 4 through a first telescopic mechanism, a plurality of twisting mechanisms are slidably installed on the second sliding frame 5, a driving mechanism is also provided on the second sliding frame 5, the twisting mechanism is drivingly connected to the driving mechanism, a wiring mechanism is installed on the front of the twisting mechanism through the second telescopic mechanism, a plug head 6 is installed at the bottom end of the wiring mechanism, a control box 7 is provided on the first sliding frame 4, and the plug head 6 is electrically connected to the control box 7.

[0037] like Figures 1 - 3As shown, the top view of the first sliding frame 4 is in a square shape. The clamping mechanism includes a first screw cavity 8 and a second screw cavity 9. At the positions near one end of the front and back sides inside the first sliding frame 4, first screw cavities 8 are respectively opened. At the positions near the other end of the front and back sides inside the first sliding frame 4, second screw cavities 9 are respectively opened. Inside both of the two first screw cavities 8, first screws 10 are coaxially and rotatably installed. Inside both of the two second screw cavities 9, second screws 11 are coaxially and rotatably installed. The first screw 10 and the second screw 11 within the same frame wall of the first sliding frame 4 are coaxially and fixedly connected by a coaxial rod 12. The thread directions of the first screw 10 and the second screw 11 within the same frame wall of the first sliding frame 4 are opposite. One side of the first sliding frame 4 is rotatably installed with a first rotating shaft 13. The inner end of the first rotating shaft 13 extends into the first sliding frame 4 and is coaxially and fixedly installed with a fourth gear 14. At one end of both of the two first screws 10 close to the first rotating shaft 13, fifth gears 15 are coaxially and fixedly installed. The two fifth gears 15 are in transmission connection with the fourth gear 14 through a second toothed belt 16. On the front frame and the back frame of the first sliding frame 4, two sliding rings 17 are respectively slidably installed. On the outer side of the bottom of the sliding ring 17, a clamping plate 60 is fixedly installed. The two sliding rings 17 are symmetric about the middle of the first sliding frame 4. The two sliding rings 17 are respectively located outside the first screw cavity 8 and the second screw cavity 9. On the inner side of the sliding ring 17, an extension plate 18 is fixedly installed. At the inner end of the extension plate 18, a screw ring 19 is fixedly installed. The screw rings 19 on the inner sides of the two sliding rings 17 are respectively in threaded connection with the first screw 10 and the second screw 11. By symmetrically and slidably installing the sliding rings 17 on the first sliding frame 4 and making the thread directions of the first screw 10 and the second screw 11 for driving the symmetric sliding rings 17 opposite, when it is necessary to detect the electric energy meter 1, only by rotating the first rotating shaft 13, the symmetric sliding rings 17 can be driven to slide towards or away from each other simultaneously, which not only facilitates fixing the device on the electric energy meter 1 to enhance the stability of the device during detection, but also enables the wiring hole 3 to be located at the middle position of the device, facilitating connection with the plug head 6.

[0038] As Figure 1 and Figure 8As shown, the first telescopic mechanism includes a first telescopic tube 20. One end of the first telescopic tube 20 is fixedly installed at the middle position on the front of the first sliding frame 4. Inside the first telescopic tube 20, a first telescopic rod 22 is slidably installed through a third spring 21.

A third helical tooth groove 23 is formed on the upper surface of the first telescopic rod 22. One end of the top wall of the first telescopic tube 20 away from the first sliding frame 4 is slidably installed through a third helical tooth plate 24. The bottom end of the third helical tooth plate 24 abuts against the third helical tooth groove 23. When the first telescopic rod 22 is pulled outwards, the position of the screwing mechanism can be adjusted so that it is directly above the flat-head screw 2. The third helical tooth groove 23 and the third helical tooth plate 24 not only do not prevent the first telescopic rod 22 from sliding outwards, but also block the retraction of the first telescopic rod 22. When the first telescopic rod 22 needs to be reset, just pull the third helical tooth plate 24 upwards.

[0039] As Figure 1 , Figure 4 and Figure 7 shown, the screwing mechanism includes a sliding seat 25. Erection sliding plates 26 are fixedly installed on both the front and back of the sliding seat 25. Erection sliding grooves 27 are formed on both the front and back inside the second sliding frame 5. The erection sliding plates 26 slide in the erection sliding grooves 27.

A matching hole 61 with a square top view is formed at the bottom end of the vertical sliding rod 30. Inside the matching hole 61, a flat-head 31 is slidably installed through a fifth spring 62. Retraction grooves 32 are formed on both sides of the vertical sliding rod 30. Retraction holes 33 are formed inside the retraction grooves 32.

The inner contraction groove 32 is connected to the pressing rod 40 through a rope hole 41. The inner sides of the first beveled tooth plate 36 and the second beveled tooth plate 37 are connected to the pressing rod 40 through a pull rope 42. The pull rope 42 is arranged to pass through the rope hole 41, and a third gear 43 is coaxially fixedly installed near the top of the outer side of the inner rotating shaft 28; by slidingly installing multiple twisting mechanisms in the second slide frame 5, the device can be used for slotted screws 2 with various spacings, by arranging the first beveled tooth plate 36 and the second beveled tooth plate 37 with opposite bevels on the vertical slide bar 30, and The inner rotating shaft 28 is provided with a first bevel tooth groove 38 and a second bevel tooth groove 39 matching the first bevel tooth plate 36 and the second bevel tooth plate 37, so that the vertical slide bar 30 cannot slide up and down on the inner rotating shaft 28 by itself. By sliding a pressing rod 40 connected to the first bevel tooth plate 36 and the second bevel tooth plate 37 in the vertical slide bar 30, it is only necessary to pinch the vertical slide bar 30 and then press the pressing rod 40 downward to disengage the first bevel tooth plate 36 and the second bevel tooth plate 37 from the first bevel tooth groove 38 and the second bevel tooth groove 39, so that the vertical slide bar 30 can be controlled to slide up and down, which is convenient for control. The slotted head 31 is set to be able to slide up and down in order to match the height of the slotted screw 2 rising or falling when it is rotated.

[0042] like Figure 1 and Figure 9 As shown, the driving mechanism includes a first gear 44, and the first gears 44 are rotatably installed at both ends of the upper surface of the second slide frame 5, the first gear 44 and the plurality of third gears 43 are in the same straight line, a gear seat 45 is fixedly installed at the middle position of the front face of the second slide frame 5, a second slide groove 46 is provided on the top of the gear seat 45, a gear shaft 47 is slidably installed inside the second slide groove 46, a top arc plate 49 is slidably installed on one side of the second slide groove 46 close to the second slide frame 5 through a fourth spring 48, the top arc plate 49 abuts against the side of the gear shaft 47, a second gear 50 is fixedly installed on the top of the gear shaft 47, a second rotating shaft 51 is fixedly installed on the top of the second gear 50, two first gears 44, one second gear 50 and a plurality of third gears 43 are connected through a first toothed belt 52 for transmission.

[0043] like Figure 4 and Figure 6As shown, internal push rods 53 are fixedly installed at both ends of the upper surface of the sliding seat 25. Both internal push rods 53 abut against the outer side of the first toothed belt 52. A first sliding groove 54 is formed in the upper surface of the sliding seat 25. The first sliding groove 54 is located on the side of the inner rotating shaft 28. An outer push rod 55 is slidably installed inside the first sliding groove 54. The outer push rod 55 is located inside the first toothed belt 52. The outer side of the outer push rod 55 is connected to the outer side of the first sliding groove 54 through a first spring 56. A limiting sliding groove 57 is formed on the side of the first sliding groove 54. A limiting sliding plate 58 is fixedly installed on the side of the outer push rod 55. The limiting sliding plate 58 slides inside the limiting sliding groove 57. A transverse push rod 59 is fixedly installed inside the outer push rod 55. The other end of the transverse push rod 59 penetrates through the sliding seat 25 and extends to the outside of the sliding seat 25. By setting the internal push rod 53 to abut against the outer side of the first toothed belt 52, the first toothed belt 52 can be fully contacted with the third gear 43, so that when the operator rotates the second gear 50, it can be ensured that the third gear 43 is rotated through the first toothed belt 52, thereby driving multiple vertical sliding rods 30 simultaneously, enabling the device to loosen or tighten multiple flat head screws 2 simultaneously, improving work efficiency. By setting the outer push rod 55, when it is necessary to slide a certain sliding seat 25, only need to press the transverse push rod 59 to make the outer push rod 55 abut against the inner side of the first toothed belt 52, so that the first toothed belt 52 is separated from the third gear 43, which can prevent a rotating vertical sliding rod 30 from driving other vertical sliding rods 30 with adjusted positions and heights to rotate, thereby damaging the flat head screws 2.

[0044] As Figure 1 and Figure 10 As shown, the second telescopic mechanism includes a second telescopic tube 63. The second telescopic tube 63 is fixedly installed on the front surface of each sliding seat 25. A second telescopic rod 65 is slidably installed inside the second telescopic tube 63 through a sixth spring 64. One end of the second telescopic rod 65 away from the sliding seat 25 extends to the outside of the second telescopic tube 63 and is fixedly installed with a third sliding frame 66.

[0045] As Figure 1 As shown, the wiring mechanism includes a lifting sliding rod 67. The lifting sliding rod 67 is vertically and slidably installed through each third sliding frame 66.
