[0013] The present invention provides an electric meter that is easy to disassemble and maintain, and has the following technical points and beneficial effects: 1. The present invention uses devices such as a liquid storage tube, a buckle and a bellows. When the wiring in the wiring port is powered off by pulling down the safety switch, the magnetic particles of the magnetorheological fluid lose the guidance of the magnetic field and return to the free-flowing Newtonian fluid state. At this time, the buckle moves backward under the pull of the springs on both sides of the movable box, thereby canceling the buckle of the clamping rod, and then releasing the clamping plate, so that the wiring can be freely pulled out, and at the same time, the pressure plate pops up, so that the maintenance personnel can find the wiring port corresponding to the wiring for rapid positioning maintenance.

[0014] 2. The present invention uses devices such as buckles, sleeve rods and pressure rods. When it is necessary to take out the wires in the wiring ports at the same time, the push blocks on both sides are pushed backward to slide in the openings, and the pressure rods are driven to slide inwardly of the movable grooves by the push blocks. At this time, the pressure rods simultaneously push the buckles inwardly, so that the buckles cancel the fastening of the clamping rods, and the pressure plate is released. The movable pressure rod bounces upward under the action of the electromagnetic spring coil, and the clamp is loosened, so that the wires can be easily pulled out from the wiring ports at the same time. At this time, the staff can easily replace or check the wires in all wiring ports.

[0015] 3. The present invention uses devices such as a buckle, a pressing rod and a sleeve rod. When it is necessary to take out the wiring in the wiring port separately, the buckle is moved synchronously to the inside of the movable groove by pressing the pressing rod, so that the buckle cancels the buckling of the clamping rod. When the wiring in the wiring port is maintained or replaced, the movable pressing rod is pressed down by pressing the pressure plate and the electromagnetic spring coil is pressed down at the same time, so that the electromagnetic spring coil presses the sleeve rod downward under the elastic potential energy, so that the clamping plate under the sleeve rod presses and clamps the wiring, and the buckle re-fastens the clamping rod to install and use the wiring.

[0016] 4. The present invention uses devices such as sliding rods, pressure rods and push blocks. When it is necessary to remove the wiring terminal from the electric meter for maintenance, the wiring connected to the power supply of the wiring port is first powered off. The maintenance personnel press the sliding rods in the openings on both sides to squeeze the two sides of the pressure rod, and then the pressure rod running through the openings on both sides undergoes elastic deformation and shrinks into the wiring terminal. At this time, the wiring terminal is pulled outward and then taken out of the installation slot.

[0017] 5. The present invention uses devices such as fixing plugs, sockets and fixing rods. The maintenance personnel can install the electric meter on a wall, an electric meter box or other supporting structures by rotating the fixing plug. The electric meter cover is engaged with the socket inside the electric meter through the fixing rod below it, thereby realizing the installation of the electric meter cover. When the electric meter cover needs to be removed from the electric meter, the maintenance personnel can buckle the electric meter cover from the electric meter through the slot, and the fixing plug passes through the inside of the fixing hole and is engaged with the socket, so that the maintenance personnel can manually rotate the fixing plug to install and disassemble the circuit board, thereby facilitating the maintenance personnel to disassemble, maintain and use the electric meter and other devices.

A clamping rod 901 is fixedly installed on both sides of one end of the pressure plate 9. A movable pressure rod 902 is installed movably on the lower side of the pressure plate 9. A sleeve rod 903 is nested and installed below the movable pressure rod 902. The sleeve rod 903 penetrates and is movably installed on the inner side of the wiring port 301. An electromagnetic spring ring 9031 is installed on the inner side of the sleeve rod 903. A clamping plate 904 for clamping the wiring is fixedly installed below the sleeve rod 903. A movable groove is provided on the inner side of the wiring terminal 3. Buckles 11 are provided on both sides of the movable pressure rod 902, and the clamping rod 901 is fixedly installed on the inner side of the wiring terminal 3. The buckle 11 is movably mounted in the movable groove, a push rod 10 is provided on one side of the buckle 11, and the push rod 10 is movably mounted in the movable groove, a movable box 12 is fixedly installed at equal intervals on the inner side of the movable groove, a mounting box 1202 is provided in the middle of the movable box 12, and the mounting box 1202 is fixedly installed in the movable groove, a bellows 1201 is fixedly installed in the middle of the inner side of the movable box 12, and a liquid storage tube 1203 filled with magnetorheological fluid is fixedly connected to the inner side of the mounting box 1202, a flow slot 304 is provided on the inner side of the wiring terminal 3, and the bellows 1201 is connected to the liquid storage tube 1203 through the flow slot 304; As an embodiment of the present invention, Figures 1 to 14 As shown, a pressing rod 13 is provided below the push rod 10, and the pressing rod 13 is movably mounted in the movable groove and passes through the openings on both sides of the connecting terminal 3. The pressing rod 13 is closely connected with the sliding rod 201 by passing through the openings on both sides of the connecting terminal 3; During operation, the terminal block 3 is installed and used through the installation slot 8, and the pressure plate 9 is installed and used through the installation block 303. When the terminal block 3 needs to be disassembled from the electric meter 1 for maintenance, the wiring connected to the power supply of the wiring port 301 is first powered off, and the maintenance personnel press the slide bars 201 in the openings on both sides to squeeze the two sides of the pressure bar 13, so that the pressure bar 13 running through the openings on both sides undergoes elastic deformation and retracts into the terminal block 3. At this time, the terminal block 3 is pulled outward and then taken out of the installation slot 8. When the maintenance is completed, the terminal block 3 is reinstalled back to its original position. At this time, the elastic potential energy of the pressure bar 13 pushes the slide bar 201 out of the push block 2, and then the slide bar 201 is reset, and the pressure bar 13 is buckled and fixed by the push block 2, and then the terminal block 3 is installed in the installation slot 8 for use; Since the pressure rod 13 running through the openings on both sides is engaged with the push block 2, when it is necessary to take out the wires in the wiring port 301 at the same time, the push blocks 2 on both sides are pushed backward to make them slide in the openings, and the push blocks 2 drive the pressure rod 13 to slide to the inside of the movable groove. At this time, the pressure rod 13 simultaneously pushes the buckle 11 inward, so that the buckle 11 cancels the buckle of the clamping rod 901, and the pressure plate 9 is released. The movable pressure rod 902 bounces upward under the action of the electromagnetic spring coil 9031, and the clamping plate 904 is loosened, so that the wires are conveniently drawn out from the wiring port 301 at the same time. At this time, the staff can easily replace or check the wires in all the wiring ports 301, and secondly, the reset spring 202 is used to reset the push block 2. When the wires in the wiring port 301 are taken out separately, the pressure rod 10 is pressed to make The buckle 11 moves synchronously toward the inside of the movable groove, and similarly, the buckle 11 cancels the buckling of the clamping rod 901. Since the pressure rod 13 is staggered below the push rod 10, when the wiring in the wiring port 301 is taken out separately, the buckling state of the pressure rod 13 and the remaining buckles 11 will not be affected, so as to ensure the independence of the operation. At this time, the staff can check the wiring in the wiring port 301 separately. When the wiring in the wiring port 301 is maintained or replaced, the movable pressure rod 902 is pressed down by pressing the pressure plate 9 and the electromagnetic spring coil 9031 is pressed down at the same time, so that the electromagnetic spring coil 9031 presses the sleeve rod 903 downward under the elastic potential energy, so that the clamping plate 904 below the sleeve rod 903 presses and clamps the wiring, and the buckle 11 re-fastens the fixed clamping rod 901 to install and use the wiring; When the wiring is long and entangled with each other, it is not convenient to inspect and maintain the safety switch corresponding to the wiring in the wiring port 301. Therefore, in the design of the wiring terminal 3, a movable box 12 and an installation box 1202 are added, and a liquid storage tube 1203 is provided in the installation box 1202, and a bellows 1201 is provided in the movable box 12. The spring and the push plate in the installation box 1202 squeeze the magnetorheological fluid through the flow groove 304 and transport it to the bellows 1201. When the electromagnetic spring coil 9031 is connected to the conductive sheet 302, the current flows through the electromagnetic spring coil 9031, which will cause it to generate a magnetic field. At this time, the magnetic particles in the magnetorheological fluid will quickly arrange along the direction of the magnetic field to form a chain or columnar structure, the viscosity of the fluid will increase sharply, and the fluidity will decrease, so that the magnetorheological fluid will be converted into a Bingham fluid (Bingham fluid is also called plastic fluid, which means that when the cutting When the stress reaches a certain yield stress, shear deformation begins to occur, and the deformation rate and shear stress are linearly related). At this time, the magnetorheological fluid in the form of Bingham fluid in the bellows 1201 will support the buckle 11 to prevent the springs on both sides of the movable box 12 from pulling the buckle 11 inward under the elastic potential energy, so that it cancels the buckle on the clamping rod 901. When the wiring in the wiring port 301 is powered off by pulling down the safety switch, the magnetic particles of the magnetorheological fluid lose the magnetic field guidance and return to the free-flowing Newtonian fluid state. At this time, the buckle 11 moves backward under the pull of the springs on both sides of the movable box 12, thereby canceling the buckle on the clamping rod 901, and then releasing the clamp 904, so that the wiring can be freely drawn out, and at the same time, the pressure plate 9 pops up, so that the maintenance personnel can find the wiring port 301 corresponding to the wiring for rapid positioning maintenance.

At the same time, the anti-slip sheet on the pressing block 103 can effectively prevent the reporting template 102 from sliding during use, so as to ensure that the reporting template 102 can be tightly installed on the partition 106. After receiving the signal transmitted by the circuit board 105, the data is processed and analyzed by its internal processor, and the basic data of the electric meter 1 is displayed in real time through the display 107, so as to facilitate the maintenance personnel in monitoring the operating status of the equipment. Secondly, the fixing plug 7 passes through the inner side of the fixing hole and is engaged with the socket 104, so that the maintenance personnel can install and disassemble the circuit board 105 by manually rotating the fixing plug 7.

When the power connection is inserted into the connection port 301, power is transmitted to the power connection sheet 109 through the conductive sheet 302, so that the circuit board 105 and the reporting template 102 are powered and used.

[0025] Working principle: During installation, the maintenance personnel install the electric meter 1 on a wall, an electric meter box or other supporting structure by rotating the fixed plug 7. The electric meter cover 4 is engaged with the socket 104 on the inner side of the electric meter 1 through the fixed plug rod 401 below it, so as to realize the installation of the electric meter cover 4. When it is necessary to remove the electric meter cover 4 from the electric meter 1, the maintenance personnel can buckle the electric meter cover 4 from the electric meter 1 through the slot 101. An observation window 5 is provided on one side of the electric meter cover 4 to facilitate the maintenance personnel to observe the data displayed on the display 107 inside the electric meter 1 on site, and the reporting template 102 below the other side is used for data exchange and communication to transmit the data detected by the electric meter 1 to the external monitoring equipment. The partition 106 installed by the inner side of the electric meter 1 is used to install the reporting template 102, and the circuit board 105 inside the electric meter 1 can be installed at the same time. The electric meter 1 is isolated from other components to reduce interference and improve the stability and safety of the electric meter 1. The reporting template 102 is installed and used by inserting it between the pressing blocks 103. At the same time, the anti-slip sheet on the pressing block 103 can effectively prevent the reporting template 102 from sliding during use, so as to ensure that the reporting template 102 can be tightly installed on the partition 106. Secondly, the fixing plug 7 passes through the inner side of the fixing hole and is engaged with the plug hole 104, so that the maintenance personnel can install and disassemble the circuit board 105 by manually rotating the fixing plug 7. At the same time, the power connection sheet 109 is fitted with the conductive sheet 302. When the power connection is inserted into the connection port 301, the conductive sheet 302 transmits power to the power connection sheet 109, so that the circuit board 105 and the reporting template 102 are powered and used; When it is necessary to remove the terminal block 3 from the electric meter 1 for maintenance, first disconnect the power supply of the wiring connected to the power supply port 301, and the maintenance personnel press the slide bars 201 in the openings on both sides to squeeze the two sides of the pressure bar 13, so that the pressure bar 13 running through the openings on both sides undergoes elastic deformation and retracts into the terminal block 3, and then the terminal block 3 is pulled outward and then taken out of the installation slot 8. When the maintenance is completed, the terminal block 3 is reinstalled back to its original position, and the elastic potential energy of the pressure bar 13 is used to push the slide bar 201 out of the push block 2, and then the slide bar 201 is reset, and the pressure bar 13 is buckled and fixed by the push block 2, and then the terminal block 3 is installed in the installation slot 8 for use; When the wires in the wiring port 301 need to be taken out at the same time, the push blocks 2 on both sides are pushed backward to make them slide in the opening, and the push blocks 2 drive the pressure rod 13 to slide inward of the movable groove. At this time, the pressure rod 13 simultaneously pushes the buckle 11 inward, so that the buckle 11 cancels the buckling of the clamping rod 901, and the pressure plate 9 is released. The movable pressure rod 902 bounces upward under the action of the electromagnetic spring coil 9031, and the clamping plate 904 is loosened, so that the wires can be easily drawn out from the wiring port 301 at the same time. At this time, the staff can easily replace or check the wires in all the wiring ports 301, and then the reset spring 202 is used to push the push rod 13 ... Block 2 is reset. When the wiring in the wiring port 301 is taken out separately, the buckle 11 is synchronously moved to the inner side of the movable groove by pressing the push rod 10, and similarly, the buckle 11 cancels the buckling of the clamping rod 901. When the wiring in the wiring port 301 is maintained or replaced, the movable pressing rod 902 is pressed down by pressing the pressing plate 9 and the electromagnetic spring coil 9031 is pressed down at the same time, so that the electromagnetic spring coil 9031 presses the sleeve rod 903 downward under the elastic potential energy, so that the clamping plate 904 under the sleeve rod 903 presses and clamps the wiring, and the buckle 11 re-fastens the fixed clamping rod 901, so that the wiring is installed and used; When the wiring is long and entangled with each other, the magnetorheological fluid is squeezed and transported to the bellows 1201 through the flow slot 304 by the spring and push plate in the installation box 1202. When the electromagnetic spring coil 9031 is connected to the conductive sheet 302, the current flows through the electromagnetic spring coil 9031 to generate a magnetic field. At this time, the magnetic particles in the magnetorheological fluid will quickly arrange along the magnetic field direction to form a chain or columnar structure, the viscosity of the fluid will increase sharply, and the fluidity will decrease, so that the magnetorheological fluid will be converted into a Bingham fluid. At this time, the magnetorheological fluid in the form of a Bingham fluid in the bellows 1201 will support the buckle 11 to prevent The springs on both sides of the movable box 12 pull the buckle 11 inward under the elastic potential energy, so that it cancels the buckle on the clamping rod 901. When the wiring in the wiring port 301 is powered off by pulling down the safety switch, the magnetic particles of the magnetorheological fluid lose the magnetic field guidance and return to the free-flowing Newtonian fluid state. At this time, the buckle 11 moves backward under the pull of the springs on both sides of the movable box 12, thereby canceling the buckle on the clamping rod 901, and then releasing the clamp 904, so that the wiring can be freely pulled out, and at the same time, the pressure plate 9 pops up, so that the maintenance personnel can find the wiring port 301 corresponding to the wiring for quick positioning maintenance.

[0026] It should be noted that when the buckle 11 cancels the fastening of the clamping rod 901, since the electromagnetic spring coil 9031 is provided in the sleeve rod 903, the elastic potential energy of the electromagnetic spring coil 9031 is released, and at the same time, the clamping plate 904 is provided with a clamping tooth under it, so that the clamping plate 904 can maintain a certain clamping degree on the wiring to prevent the wiring from escaping from the wiring port 301. When the pressure plate 9 is pushed upward, the sleeve rod 903 is driven to rise by the movable pressure rod 902 to cancel the clamping of the clamping plate 904 on the wiring to prevent the wiring from directly escaping from the wiring port 301 when the power is not turned on. When the buckle 11 is fastened to the clamping rod 901, it is necessary to pull the push rod 10 to drive the buckle 11 to move forward to overcome the pulling force of the springs on both sides of the movable box 12 on the buckle 11.
