Description
Technical Field
[0001] This utility model belongs to the field of electricity meter technology, and in particular relates to an installation structure for an electricity meter. Background Technology
[0002] Electricity meters are instruments used in power systems to measure and meter electricity consumption. They are widely used in residential electricity consumption, industrial and commercial power distribution, and power operation and maintenance, and are core devices for electricity metering and management. In actual installation, electricity meters are typically fixed on standard mounting rails within distribution boxes. The performance of their mounting structure directly affects the assembly efficiency and operational stability of the electricity meter. Currently, most electricity meters use a spring-clip structure. This structure relies on the elastic deformation of the clips to engage with the mounting rail. During installation, significant pressure is applied to the meter to deform the clips and allow them to engage with the rail. Disassembly requires special tools to pry the clips, making the overall disassembly and assembly inconvenient and inefficient. Furthermore, the elastic clips are constantly under deformation and stress, making them prone to elastic fatigue and decreased clamping force. This poses a risk of loosening and displacement under vibration, resulting in insufficient reliability. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0015] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0016] Example 1:
[0017] This embodiment provides an installation structure for an electricity meter, including an electricity meter body, which includes: The housing 1 has a connected mounting groove 11 and a slot 12 on its back side; The first card block 2 is movable in the mounting groove 11 along the Z direction. The first card block 2 is provided with a storage groove 21. The storage groove 21 is provided with a first contact slope 22 and a second contact slope 23 on both sides along the Z direction. The second locking block 3 is disposed on the housing 1 and located on the side of the slot 12 away from the mounting slot 11 along the Z direction; Pushing block 4 is movable in the X direction and is disposed in the storage groove 21. Pushing block 4 is provided with a first extrusion end face 41 and a second extrusion end face 42. A driving component, mounted on housing 1, is used to drive the pusher block 4 to move along the X direction; When the first extrusion end face 41 moves along the X direction and approaches the first contact slope 22, the pusher block 4 is used to push the first clamping block 2 to move along the Z direction and approach the second clamping block 3. When the second extrusion end face 42 moves along the X direction and approaches the second contact slope 23, the pusher block 4 is used to push the first clamping block 2 to move along the Z direction and away from the second clamping block 3.
[0018] In this technical solution, the back of the housing 1 of the main body of the electricity meter is formed with an interconnected mounting groove 11 and a slot 12. The mounting groove 11 is recessed along the Z direction to accommodate moving parts such as the first slot 2, the pusher block 4 and the drive component. The slot 12 is located on one side of the mounting groove 11 along the Z direction, and the slot opening faces the same direction as the mounting groove 11. It is used to cooperate with the side of the external mounting rail for positioning.
[0019] The first locking block 2 is a block-shaped transmission locking component, which can be reciprocated along the Z-direction and assembled inside the mounting groove 11 to cooperate with the second locking block 3 to clamp the external mounting rail. The first locking block 2 has a storage groove 21 that runs through the X-direction inside. The two inner side walls of the storage groove 21 along the Z-direction are respectively formed with a first contact slope 22 and a second contact slope 23 to receive the X-direction extrusion force of the pusher block 4 and convert it into Z-direction driving force. Furthermore, the first locking block 2 has a sliding groove 24 arranged along the Z-direction. A slider is provided on the housing 1. The cross-sectional shape of the sliding groove 24 is adapted to the slider on the housing 1. The slider is embedded in the sliding groove 24, so that the first locking block 2 can only slide relative to the housing 1 along the Z-direction, restricting the displacement of the first locking block 2 in the X and Y directions.
[0020] The second locking block 3 is a fixed locking component, which is a block-shaped protrusion structure and is integrally formed on the back of the housing 1. It is located at the edge of the slot 12 along the Z direction away from the mounting slot 11. The side of the second locking block 3 facing the slot 12 forms a straight locking edge, which is used to lock and position with one edge of the external mounting rail. It cooperates with the first locking block 2, which can move in the Z direction, to clamp the two sides of the external mounting rail and realize the installation and fixation of the main body of the electricity meter.
[0021] The pusher block 4 is a block-shaped transmission conversion component that is reciprocatingly mounted inside the storage slot 21 of the first clamping block 2 along the X-direction. The pusher block 4 has a first extrusion end face 41 and a second extrusion end face 42 formed at its two ends along the Z-direction. Both end faces are inclined surfaces, and their inclination angles are consistent with the first contact inclined surface 22 and the second contact inclined surface 23 within the storage slot 21, allowing them to come into contact. The reciprocating movement of the pusher block 4 along the X-direction causes the first extrusion end face 41 and the first contact inclined surface 22 to abut, or the second extrusion end face 42 and the second contact inclined surface 23 to abut, thereby pushing the first clamping block 2 to move into the clamping slot 12 or back into the mounting slot 11.
[0022] Furthermore, the driving component includes a rotating rod 5 and a knob 6. The rotating rod 5 is rotatably mounted on the housing 1 and is arranged along the X-direction. The rotating rod 5 is provided with a threaded section 51. The pusher block 4 is threadedly connected to the threaded section 51. When the rotating rod 5 rotates around its own axis, it can drive the pusher block 4 to reciprocate along the X-direction. One end of the rotating rod 5 protrudes through the side wall of the housing 1 and extends to the outside of the housing 1. The knob 6 is assembled at the end of the rotating rod 5 that protrudes from the housing 1 and is circumferentially fixed to the rotating rod 5. The user can rotate the knob 6 to drive the rotating rod 5 to rotate synchronously. Furthermore, the outer circumferential surface of the knob 6 is formed with multiple spaced anti-slip textures to increase the friction of the contact surface and facilitate the user to apply force to rotate the knob 6.
[0023] The installation and disassembly process of the electricity meter mounting structure is as follows: When the electricity meter body needs to be installed, first align the slot 12 on the back of the housing 1 with one edge of the external mounting rail, so that the side of the mounting rail is embedded in the slot 12, and the second locking block 3 abuts against the edge of the mounting rail on that side; then turn the knob 6 to drive the rotating rod 5 to rotate around its own axis, and through the threaded section 51 and the threaded transmission of the pusher block 4, drive the pusher block 4 to move in the X direction toward the first contact inclined surface 22. The first pressing end face 41 of the pusher block 4 gradually comes into contact with and presses the first contact inclined surface 22 of the first locking block 2. Under the action of the component force of the inclined surface, the first locking block 2 moves in the Z direction toward the second locking block 3, gradually extends out of the mounting groove 11 and abuts against the other edge of the mounting rail. Finally, the first locking block 2 and the second locking block 3 together clamp the external mounting rail, and the installation and fixing of the electricity meter body is completed. The rigid clamping structure adopts a rotating rod 5 threaded drive and inclined plane clamping. The threaded drive itself has a self-locking characteristic. After being clamped in place, the first clamping block 2 will not retract on its own due to external vibration, and the clamping state is stable and durable.
[0024] When it is necessary to disassemble the main body of the electricity meter, turn the knob 6 in the opposite direction, which will cause the rotating rod 5 to rotate in the opposite direction. The pusher block 4 moves along the X direction toward the second contact inclined surface 23. The second pressing end face 42 of the pusher block 4 gradually comes into contact with and presses against the second contact inclined surface 23. Under the action of the component force of the inclined surface, the first locking block 2 moves away from the second locking block 3 along the Z direction and gradually retracts into the mounting groove 11, releasing the clamping effect on the mounting rail. At this time, the main body of the electricity meter can be removed from the external mounting rail. The locking and unlocking action of the first locking block 2 can be completed by turning the knob 6. No additional tools are required, and no large pressing pressure or prying operation is required, making the operation process simpler.
[0025] Example 2:
[0026] This embodiment provides an installation structure for an electricity meter, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0027] Furthermore, it also includes a cover plate 7, which is detachably installed on the housing 1 to cover the mounting groove 11. The cover plate 7 is a plate-shaped protective component that is detachably assembled on the back of the housing 1 and covers the opening side of the mounting groove 11 to prevent the moving parts inside the mounting groove 11 from coming out to the Y direction, while protecting the internal structure from external dust and debris.
[0028] Furthermore, the cover plate 7 also includes a guide ridge 71, which is integrally connected to the cover plate 7 and is arranged along the X direction; the pusher block 4 is also provided with a guide groove 43 that is adapted to and connected to the guide ridge 71. By integrally forming a guide ridge 71 extending along the X direction on the side surface of the cover plate 7 facing the mounting groove 11, the guide ridge 71 has a strip-shaped protrusion structure, and its cross-sectional shape is adapted to the guide groove 43 on the pusher block 4. The guide ridge 71 is embedded in the guide groove 43. When the pusher block 4 moves along the X direction, the guide ridge 71 and the guide groove 43 cooperate to form a sliding guide, preventing the pusher block 4 from rotating synchronously with the rotating rod 5 and ensuring the linearity of the pusher block 4's movement.
[0029] Furthermore, the cover plate 7 also includes a limiting plate 72, which is integrally connected to the cover plate 7 and protrudes along the Y direction. A limiting groove 73 is formed on the limiting plate 72, and the rotating rod 5 and the limiting groove 73 are inserted and fitted along the Y direction. The limiting plate 72 is used to restrict the movement of the rotating rod 5 along the X direction. The side of the cover plate 7 facing the mounting groove 11 is also integrally formed with a limiting plate 72, which protrudes along the Y direction. The limiting plate 72 has a limiting groove 73 with an opening facing the rotating rod 5. The rotating rod 5 has a groove 52, and the rod body at the groove 52 on the rotating rod 5 is inserted into the limiting groove 73. The inner wall of the limiting groove 73 fits against the outer peripheral surface of the rotating rod 5, which can restrict the movement of the rotating rod 5 along the X direction, while not hindering the rotation of the rotating rod 5 around its own axis. The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
