Description

Technical Field

[0001] The utility model relates to the field of electric energy meters, and particularly relates to a new type of electric energy meter. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy, also known as a watt-hour meter, a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. The working principle of the electric energy meter is based on Faraday's law of electromagnetic induction. When a conductor moves in a magnetic field, an induced electromotive force will be generated, and the magnitude of this electromotive force is related to the conductor speed and magnetic field strength. Inside the electric energy meter, there is usually an aluminum disc rotor and a set of coils. The aluminum disc rotor is driven to rotate by an electric current, and the rotational angular velocity is proportional to the power of the passing current. According to the number of turns of the aluminum disc rotor and the power, the electric energy measured by the electric energy meter can be obtained.

[0003] In the prior art, electric energy meters are generally installed and fixed on the mounting plate inside the meter box by bolts. When installing the electric energy meter by bolts with the aid of auxiliary tools, the internal space of the meter box is relatively narrow, resulting in troublesome operation during the installation of the electric energy meter. Moreover, after a failure occurs during the use of the electric energy meter, it is not convenient to quickly disassemble and repair the electric energy meter, thus bringing inconvenience to the disassembly, installation, and use of the electric energy meter. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a new type of electric energy meter, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A new type of electric energy meter includes an electric energy meter body and a mounting plate. The electric energy meter body is fixedly connected to the front end of the mounting plate through a mounting mechanism at the rear end. The mounting mechanism includes positioning columns, fixing rods, compression springs, movable blocks, connecting blocks, and clamping heads. Four corner end parts of the rear end wall of the electric energy meter body are respectively fixedly connected with positioning columns, and the fixing rods are fixedly connected inside the front end wall of the positioning columns. The compression springs are sleeved outside the fixing rods. Connecting blocks are respectively fixedly connected to the rear end walls of the two movable blocks, and the connecting blocks are respectively fixedly connected to both ends of the compression springs and are movably connected to the fixing rods through connecting holes on the side walls. The clamping heads are fixedly connected to the outer side walls of the movable blocks.

[0007] Preferably, a set of left-right symmetric mounting holes are respectively opened at the upper and lower ends of the front wall of the mounting plate, and bolts are inserted and installed in the holes of the mounting holes.

[0008] Preferably, positioning cylinders are respectively fixedly installed at the four corner end parts of the front wall of the electric energy meter body, and clamping holes are respectively opened on both sides of the inner wall of the positioning cylinders.

[0009] Preferably, positioning columns are fixedly installed at the four corner ends of the rear wall of the electricity meter body, and a horizontal groove is formed on the front end wall of the positioning column, and sliding grooves are respectively formed on the top surface and the bottom surface of the groove.

[0010] Preferably, the fixing rod is fixedly installed in the groove of the groove, and a compression spring is sleeved outside the rod body of the fixing rod.

[0011] Preferably, connecting blocks are fixedly installed at the left and right ends of the compression spring respectively, and connecting holes are formed on the side walls of the connecting blocks and are movably installed on the fixing rod through the connecting holes. Sliding blocks are also fixedly installed at the upper and lower ends of the connecting blocks respectively, and the sliding blocks are movably installed in the sliding grooves. The movable block is fixedly installed on the front end wall of the connecting block, and a clamping head corresponding to the clamping hole is also fixedly installed on the outer side wall of the movable block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, after the electricity meter body is pre-installed into the meter box through bolts, when installing the electricity meter body, the positioning column on the rear end wall of the electricity meter body is inserted into the positioning cylinder on the front end wall of the installation plate. After the clamping head is resisted, it will squeeze the movable block to move inward, and force the compression spring to make a retraction operation through the connecting block. Until the positioning column completely enters the positioning cylinder, the clamping head loses the extrusion, and under the elastic stretching restoring force of the compression spring, it pushes the connecting block to make the movable block move outward until the clamping head is stuck in the clamping hole, so that the electricity meter body can be quickly clamped and fixed on the installation plate and placed in the meter box, so as to achieve the purpose of facilitating the quick installation of the electricity meter body. At the same time, when disassembling, the electricity meter body can be directly pulled out from the installation plate, so that the electricity meter body is convenient for disassembly and use.

[0020] As Figure 1 - Figure 4 shown, a new type of electric energy meter includes an electric energy meter body 1 and an installation plate 2. The electric energy meter body 1 is fixedly connected to the front end of the installation plate 2 through the installation mechanism 7 at the rear end. The installation mechanism 7 includes a positioning column 8, a fixed rod 11, a compression spring 12, a movable block 13, a connecting block 14 and a card head 17. The four corner end parts of the rear end wall of the electric energy meter body 1 are respectively fixedly connected with positioning columns 8, and the fixed rod 11 is fixedly connected inside the front end wall of the positioning column 8. The compression spring 12 is sleeved outside the fixed rod 11. Connecting blocks 14 are respectively fixedly connected to the rear end walls of the two movable blocks 13, and the connecting blocks 14 are respectively fixedly connected to both ends of the compression spring 12 and are movably connected to the fixed rod 11 through the connecting holes 15 on the side walls. The card head 17 is fixedly connected to the outer side wall of the movable block 13.

[0021] As Figure 2 shown, a set of left-right symmetric installation holes 3 are respectively opened at the upper and lower ends of the front wall of the installation plate 2, and bolts 4 are inserted into the holes of the installation holes 3. The installation plate 2 can be pre-installed and fixed into the electric meter box where the electric energy meter body 1 needs to be used through the bolts 4 in the installation holes 3 opened on the front end wall of the installation plate 2;

[0022] As Figure 2 and Figure 3 shown, positioning cylinders 5 are respectively fixedly installed at the four corner end parts of the front wall of the electric energy meter body 1, and card holes 6 are respectively opened on both sides of the inner wall of the positioning cylinder 5. The electric energy meter body 1 is installed and fixed on the installation plate 2 through the card holes 6 opened in the positioning cylinder 5 in cooperation with the installation mechanism 7;

[0023] As Figure 3 and Figure 4 shown, positioning columns 8 are respectively fixedly installed at the four corner end parts of the rear wall of the electric energy meter body 1, and a horizontal groove 9 is opened on the front end wall of the positioning column 8. Slide grooves 10 are respectively opened on the top surface and the bottom surface of the groove 9 of the groove 9. Through the groove 9 opened on the positioning column 8 and the slide grooves 10 opened in the groove 9, when the slide block 16 slides in the slide groove 10, it drives the connecting block 14 to move in the groove 9;

[0024] As Figure 3 and Figure 4 shown, the fixed rod 11 is fixedly installed in the groove 9, and a compression spring 12 is sleeved outside the rod body of the fixed rod 11. Through the fixed rod 11 arranged in the groove 9, the connecting block 14 can move along the fixed rod 11 in the groove 9 through the connecting hole 15, and squeeze the compression spring 12 outside the fixed rod 11 to make a retraction operation. On the contrary, the compression spring 12 can also make a recovery and extension operation to push the connecting block 14 to move in the groove 9 in both side directions;

[0025] As Figure 3 and Figure 4 shown, connecting blocks 14 are fixedly installed at the left and right ends of the compression spring 12 respectively, and a connecting hole 15 is opened on the side wall of the connecting block 14 and the connecting block 14 is movably installed on the fixed rod 11 through the connecting hole 15. Sliders 16 are also fixedly installed at the upper and lower ends of the connecting block 14 respectively, and the sliders 16 are movably installed in the chute 10. The movable block 13 is fixedly installed on the front end wall of the connecting block 14, and a chuck 17 corresponding to the card hole 6 is also fixedly installed on the outer side wall of the movable block 13. When the positioning column 8 is inserted into the positioning cylinder 5 during the installation of the electricity meter body 1, the chucks 17 on the outer walls of the connecting blocks 14 at both sides of the rear end of the positioning column 8 will be blocked by the positioning cylinder 5 in advance. When the positioning column 8 is continuously inserted into the positioning cylinder 5 after being blocked, the chuck 17 will squeeze the movable block 13 in the inner side direction. The connecting block 14 installed on the rear end wall of the movable block 13 will move along the fixed rod 11 in the groove 9 through the connecting hole 15 on the side wall, and the sliders 16 installed at the upper and lower ends of the connecting block 14 will slide in the chute 10 opened on the inner wall of the groove 9, and force the compression spring 12 sleeved outside the fixed rod 11 to make a retraction operation. Until the positioning column 8 completely enters the positioning cylinder 5, the chuck 17 will lose the extrusion of the inner wall of the positioning cylinder 5, and the compression spring 12 will make an elastic recovery and extension operation, and push the connecting blocks 14 at both ends in the outer side direction. The connecting block 14 will drive the movable block 13 to move in the outer side direction until the chuck 17 on the outer side wall of the movable block 13 is inserted into and stuck in the card holes 6 opened on both sides of the inner wall of the positioning cylinder 5, so that the electricity meter body 1 can be quickly clamped, installed and fixed on the mounting plate 2 and placed in the electricity meter box for use.

[0026] It should be noted that the present utility model is a new type of electric energy meter. The mounting plate 2 can be pre-installed and fixed as a pre-installed part into the meter box where the electric energy meter body 1 needs to be used through the bolt 4 in the mounting hole 3 opened on the front end wall of the mounting plate 2. When installing the electric energy meter body 1, the positioning columns 8 installed at the four corner ends of the rear end wall of the electric energy meter body 1 are positioned and inserted into the positioning cylinders 5 installed at the four corner ends of the front end wall of the mounting plate 2. The movable blocks 13 on both sides of the rear end wall of the positioning column 8 will enter the positioning cylinder 5 in advance. At this time, when the clamping heads 17 installed on the outer wall of the movable block 13 are resisted by the positioning cylinder 5, the clamping heads 17 will push the movable block 13 in the inner direction. When the movable block 13 moves in the inner direction, the connecting block 14 installed on the rear end wall of the movable block 13 will move along the fixing rod 11 through the connecting hole 15 opened on the side wall in the groove 9 opened on the positioning column 8. And the connecting holes 15 installed at the upper and lower ends of the connecting block 14 will slide in the sliding groove 10 opened on the inner wall of the groove 9, and force the compression spring 12 sleeved outside the fixing rod 11 to make a retraction operation. And the clamping head 17 will closely adhere to the inner wall of the positioning cylinder 5 under the reverse elastic force of the compression spring 12. Until the movable block 13 and the positioning column 8 completely enter the interior of the positioning cylinder 5, the clamping head 17 will lose the extrusion force of the inner wall of the positioning cylinder 5. At this time, the compression spring 12 will make an elastic recovery and extension operation, and push the connecting blocks 14 at both ends in opposite directions. And the connecting block 14 will drive the movable block 13 to push in the outer direction until the movable block 13 closely adheres to the inner wall of the positioning cylinder 5, and the clamping head 17 installed on the outer side wall of the movable block 13 is inserted into the clamping holes 6 opened on both sides of the inner wall of the positioning cylinder 5. Thus, the electric energy meter body 1 can be quickly clamped and installed and fixed on the mounting plate 2 and placed in the meter box for use, so as to achieve the purpose of facilitating the quick installation of the electric energy meter body 1. Finally, when the electric energy meter body 1 fails during use and needs to be disassembled, the electric energy meter body 1 can be directly pulled out from the mounting plate 2, thereby making the electric energy meter body 1 convenient for disassembly and assembly and use.

[0027] In summary, the above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components therein can be replaced with equivalents, or some of the technical features can be equivalently replaced. All should be included within the protection scope of the present utility model within the spirit and principle of the present utility model.
