Description

Technical Field

[0001] This invention relates to the field of power facility technology, specifically to an electricity meter and its usage method. Background Technology

[0002] Patent CN222014306U discloses an anti-theft power meter, belonging to the field of power equipment technology. The meter includes a wiring terminal at the bottom and an anti-detachment slide rail embedded on one side of the lower part of the meter. An anti-theft cover is installed inside the anti-detachment slide rail via a slider. A positioning recess is fixedly installed on the side of the meter near the wiring terminal, and an alarm device that can detect the opening of the anti-theft cover is installed inside the positioning recess.

[0003] In existing technology, when connecting cables to electricity meters, the cable is usually inserted into the connection hole, and then the locking bolt is tightened with a screwdriver to lock the cable. This requires tightening the locking bolt one by one after inserting the cable, which is a slow installation process.

[0004] Therefore, an electricity meter and its usage method are proposed to solve the problems mentioned above. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: It includes a power meter body with a display screen; the lower end of the power meter body has multiple sets of insertion holes for inserting wires, and a force-bearing rod is slidably connected to the side wall of each insertion hole; a drive motor is bolted to the side wall of the power meter body, and a sliding hole is embedded in the surface of the power meter body; the inner side wall of the power meter body is hollowed out to form a cavity, and a sliding plate is slidably connected within the cavity; the sliding plate is fixedly connected to the other end of the force-bearing rod, and the side wall of the sliding plate is fixedly connected to the other side wall of the cavity via a spring; A tightening rod is threadedly connected to the upper part of the insertion hole; a drive shaft is rotatably connected to the inner side wall of the power meter body, one end of which is inserted into the first connecting assembly. The first connecting assembly is fixedly connected to the worm gear, which meshes with the worm wheel. The bottom axis of the worm wheel is fixedly connected to the second connecting assembly, and the rotating shaft at the upper end of the first gear is inserted into the second connecting assembly. When the cable is inserted into the insertion hole, the drive shaft locks with the worm gear and the worm wheel locks with the first gear. When the cable is fixed, the drive shaft separates from the worm gear and the worm wheel separates from the first gear, so that the cable is quickly locked with the tightening rod when inserted into the insertion hole.

[0006] In one possible implementation, the first gear meshes with the second gear, the second gear meshes with the third gear, and the lower ends of the first gear and the third gear are each connected to an inner shaft. The inner shaft is slidably inserted into the outer shaft, and the bottom of the outer shaft is fixedly connected to the tightening rod. A ring is fixedly connected to the outer shaft side wall below the first gear.

[0007] In one possible implementation, a telescopic rod is provided below the collar. The telescopic rod consists of an inner rod and an outer rod that are slidably connected to each other. A tension spring is fixedly connected to the lower part of the outer rod, and the upper end of the tension spring is fixedly connected to the bottom of the inner rod.

[0008] In one possible implementation, the bottom of the outer rod is fixedly connected to a tension spring, the top of the inner rod is fixedly connected to an upper connecting rope, the bottom of the inner rod is fixedly connected to a lower connecting rope, and the lower end of the lower connecting rope slides through the bottom of the telescopic rod and extends outward through a sliding hole.

[0009] In one possible implementation, the second connecting component and the first connecting component have the same structure, and both the second connecting component and the first connecting component are provided with adjustment components at their outer ends. The adjustment components are connected to the cavity through a guide tube.

[0010] In one possible implementation, the second connecting assembly includes a connecting sleeve and an insertion rod. Multiple sets of insertion rods are slidably connected to the inner wall of the connecting sleeve. A connecting spring is connected to the bottom of the insertion rod, and the other end of the connecting spring is fixedly connected to the inner wall of the connecting sleeve.

[0011] In one possible implementation, the adjustment component includes a flow guide frame, a movable rod slidably connected within the flow guide frame, and the other end of the movable rod being fixedly connected to a return spring. A one-way valve is installed at the bottom of the flow guide frame, and the valve core of the one-way valve is connected to the upper connecting rope.

[0012] In one possible implementation, the other end of the reset spring is fixedly connected to the moving rod, the other end of the moving rod is fixedly connected to the repulsion plate, the flow guide frame is connected to the flow guide pipe, and the two sets of flow guide frames are connected to each other.

[0013] In one possible implementation, the upper regions of the drive shaft and worm gear are provided with multiple sets of embedded through holes on the surface of the inner region of the connecting sleeve.

[0014] A method for using an electricity meter includes the following steps: Step 1: When working, when connecting the wire to the insertion hole, remove the outer sheath of the cable portion at the upper end of the wire, and then insert it into the insertion hole. The surface of the wire presses against the force rod, causing the force rod to push the sliding plate to move. The sliding plate pushes the air in the cavity into the guide tube. Step 2: The guide tube delivers air into the guide frame, and the air pushes the repulsion plate closer to the insertion rod. The insertion rod is pushed by the magnetic force and squeezes into contact with the side wall of the drive shaft, so that the drive shaft and the worm gear are locked together. Another set of insertion rods are locked with the worm wheel. The drive motor drives the drive shaft to rotate, and the drive shaft also drives the worm wheel in the insertion hole area where the wire is inserted to rotate. Step 3: The worm gear drives the first gear to rotate through the second connecting component. The first gear drives the third gear to rotate through the second gear. The first gear and the third gear drive the outer shaft to rotate through the inner shaft. The two sets of outer shafts drive the two sets of tightening rods to rotate simultaneously. The two sets of tightening rods move downwards to squeeze and fix the wire below.

[0015] Compared with the prior art, the present invention provides an electricity meter and its usage method, which has the following beneficial effects: 1. When the wire is inserted into the insertion hole, the surface of the wire presses against the force rod, pushing the sliding plate to move. This allows air in the cavity to enter the guide frame through the guide tube, pushing the repulsion plate to lock the insertion rod with the drive shaft and worm gear. The drive motor drives the drive shaft to rotate, and through gear transmission, the tightening rod moves downward to press and fix the wire. The whole process realizes automatic locking and fixing after the cable is inserted, eliminating the need for manual operation of the tightening rod, improving installation efficiency and reducing operation difficulty.

[0016] 2. After the cable is fixed, the outer shaft moves downward to squeeze the telescopic rod, and the inner rod moves downward to open the one-way valve core through the upper connecting rope. The negative pressure in the guide frame disappears, the reset spring drives the repulsion plate to reset, and the insertion rod disengages from the drive shaft and worm gear, realizing the separation of the drive shaft from the worm and the worm gear from the first gear. This allows the drive motor to continue rotating after a set of cables is fixed without driving the worm gear above the area where the cables have been locked. Multiple sets of cables can be fixed and installed sequentially without interference between them, improving the accuracy and flexibility of the installation.

[0017] 3. When it is necessary to disassemble the cable, the present invention drives the third gear to rotate by twisting the active tightening shaft, and then drives the first gear to rotate through the second gear, thereby causing the tightening rod to move upward and lose the squeezing of the cable, thus conveniently and quickly achieving the initial loosening of the cable.

[0018] 4. In this invention, the cable is pulled outward and the lower connecting rope is pulled. The lower connecting rope drives the one-way valve to open through the telescopic rod and the upper connecting rope, so that the air inside the guide frame can be connected with the outside. This is conducive to the reset and movement of the sliding plate and prepares for the next cable installation. After the lower connecting rope is released, the one-way valve closes, and the space inside the guide frame is in a closed state, which ensures the stability and sealing of the internal structure of the device.

[0021] 1. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-6 The present embodiment of an electricity meter and its usage method includes an electricity meter body 1, and a display screen 2 is provided on the electricity meter body 1; The lower end of the main body 1 of the power meter is provided with multiple sets of insertion holes 3 for inserting wires. A force rod 4 is slidably connected to the side wall of the insertion hole 3. One end of the force rod 4 in contact with the cable is arc-shaped and has a rubber layer on its surface. A drive motor 5 is bolted to the side wall of the power meter body 1. A sliding hole 6 is embedded in the surface of the power meter body 1. A storage battery and a controller are provided on the power meter body 1. The storage battery provides the power required for the drive motor to work. The inner wall of the main body 1 of the power meter is hollowed out to form a cavity 7. The cavity 7 is closed. A sliding plate 8 is slidably connected inside the cavity 7. The sliding plate 8 is fixedly connected to the other end of the force rod 4. The side wall of the sliding plate 8 is fixedly connected to the other side wall of the cavity 7 by a spring. The spring provides power for the reset movement of the sliding plate 8. More specifically, a tightening rod 9 is threadedly connected to the upper part of the insertion hole 3.

[0023] Please see Figures 1-6 The inner wall of the main body 1 of the power meter is rotatably connected to a drive shaft 51. One end of the drive shaft 51 is inserted into the first connecting component 52. The first connecting component 52 is fixedly connected to the worm 53. The drive shaft 51 slides through the axis of the worm 53. The worm 53 is hollow. The worm 53 meshes with the worm wheel 54. The bottom axis of the worm wheel 54 is fixedly connected to the second connecting component 55. The rotating shaft at the upper end of the first gear 58 is inserted into the second connecting component 55. Specifically, the first gear 58 meshes with the second gear 59, the second gear 59 meshes with the third gear 510, and the lower ends of the first gear 58 and the third gear 510 are each connected to an inner shaft 511. The inner shaft 511 is slidably inserted into the outer shaft 512, and the bottom of the outer shaft 512 is fixedly connected to the tightening rod 9. Specifically, a ring is fixedly connected to the side wall of the outer shaft 512 below the first gear 58; Specifically, the first gear 58, the second gear 59, the third gear 510, and the worm gear 53 are rotatably connected to the power meter body 1; Specifically, a telescopic rod 513 is provided below the collar. The telescopic rod 513 is composed of an inner rod and an outer rod that are slidably connected to each other. The bottom of the outer rod is fixed to the inner side wall of the power meter body 1. A tension spring is fixedly connected to the lower inner part of the outer rod. The upper end of the tension spring is fixedly connected to the bottom of the inner rod. The bottom inner part of the outer rod is fixedly connected to the tension spring. The top of the inner rod is fixedly connected to the upper connecting rope 515. The bottom of the inner rod is fixedly connected to the lower connecting rope 514. The lower end of the lower connecting rope 514 slides through the bottom of the telescopic rod 513 and extends outward through the sliding hole 6. Specifically, a one-way valve is provided at the bottom of the flow guide frame 561, and the valve core of the one-way valve is connected to the upper connecting rope 515. More specifically, the second connecting component 55 and the first connecting component 52 have the same structure. The outer ends of the second connecting component 55 and the first connecting component 52 are provided with adjustment components 56, and the adjustment components 56 are connected to the cavity 7 through the guide tube 57.

[0024] Please see Figures 1-6 The second connecting component 55 includes a connecting sleeve 551 and an insertion rod 552. Multiple sets of insertion rods 552 are slidably connected to the inner wall of the connecting sleeve 551. A connecting spring is connected to the bottom of the insertion rod 552. The other end of the connecting spring is fixedly connected to the inner wall of the connecting sleeve 551. Specifically, the adjustment component 56 includes a flow guide frame 561, a movable rod 563 is slidably connected inside the flow guide frame 561, the other end of the movable rod 563 is fixedly connected to a return spring 562, the other end of the return spring 562 is fixedly connected to the movable rod 563, the other end of the movable rod 563 is fixedly connected to a repulsion plate 564, the flow guide frame 561 is connected to the flow guide pipe 57, and the two sets of flow guide frames 561 are connected to each other; Specifically, the upper regions of the drive shaft 51 and the worm gear 54 are provided with multiple sets of embedded through holes on the surface of the inner region of the connecting sleeve 551. The connecting sleeve 551 is coaxially and fixedly connected to the drive shaft 51 and the worm gear 54, so that when the insertion rod 552 is pushed outward by the magnetic force, the insertion rod 552 is inserted into the inside of the through hole. The areas where the insertion rod 552 and the repulsion plate 564 are close to each other are magnetically identical.

[0025] For more specific details, please refer to Figures 1 to 6 As shown, during operation, when connecting the wire to the insertion hole 3, the outer sheath of the cable portion at the upper end of the wire is removed, and then the wire is inserted into the insertion hole 3. The surface of the wire presses against the force rod 4, causing the force rod 4 to push the sliding plate 8 to move. The sliding plate 8 pushes the air in the cavity 7 into the guide tube 57. The guide tube 57 delivers the air to the guide frame 561. The air pushes the repulsion plate 564 closer to the insertion rod 552. The insertion rod 552 is pushed by the magnetic force and presses against the side wall of the drive shaft 51, locking the drive shaft 51 with the worm gear 53. Another set of insertion rods 552 is locked with the worm wheel 54. The drive motor 5 drives the drive shaft 51 to rotate. The drive shaft 51 simultaneously drives the worm wheel 54 in the area of ​​the insertion hole 3 where the wire is inserted to rotate. The worm wheel 54 drives the first gear 58 to rotate through the second connecting assembly 55. The first gear 58 drives the third gear 510 to rotate through the second gear 59. The first gear 58 and the third gear 510 drive the outer shaft 512 to rotate through the inner shaft 511. When the two sets of outer shafts 512 move, they simultaneously drive the two sets of tightening rods 9 to rotate. The two sets of tightening rods 9 move downwards to press and fix the wires below. At the same time, the outer shafts 512 move downwards, and the collar at the lower end of the outer shaft 512 on the first gear 58 presses against the telescopic rod 513, causing the inner rod on the telescopic rod 513 to move downwards. This moves the valve core of the one-way valve through the upper connecting rope 515, opening the valve. This eliminates the negative pressure in the guide frame 561. The return spring 562 then drives the repulsion plate 564 to reset, and the insertion rod 552... When the drive motor 5 drives the drive shaft 51 to continue rotating, it disengages from the drive shaft 51 and worm gear 54. However, the drive shaft 51 does not drive the worm gear 54 above the area where the wire is already locked. This allows the drive shaft 51 to lock with the worm 53 and the worm gear 54 to lock with the first gear 58 when the cable is inserted into the insertion hole 3. When the cable is fixed, the drive shaft 51 separates from the worm 53 and the worm gear 54 separates from the first gear 58. This is used to fix and confine multiple sets of cables inside the insertion hole 3. When it is necessary to disassemble the internal cable, the third gear 510 is rotated by twisting the active tightening shaft 5101. The third gear 510 can also drive the first gear 58 to rotate through the second gear 59. The first gear 58 and the third gear 510 can then drive the tightening rod 9 to move upward and lose the pressure on the cable. At the same time, by pulling the cable outward and pulling the lower connecting rope 514, the lower connecting rope 514 drives the one-way valve in the upper area to open through the telescopic rod 513 and the upper connecting rope 515, so that the air in the guide frame 561 is connected to the outside, which facilitates the reset and movement of the sliding plate 8. Then, the lower connecting rope 514 is released to close the one-way valve, and the space inside the guide frame 561 is in a closed state.

[0026] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections. Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.
