[0002] An electricity meter is an instrument used to measure electrical energy, prevent illegal electricity theft and data tampering, and ensure the accuracy and fairness of electricity metering. Electricity meters need to be protected from being pried open from the outside. The marks left on electricity meters after being pried open with external tools are not obvious, making it impossible for maintenance personnel to know whether the electricity meter has been pried open during maintenance or inspection. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that the traces of the electricity meter after being pried open with external tools are not obvious, which makes it impossible for maintenance personnel to know whether the electricity meter has been pried open during maintenance or inspection. Thus, an ultrasonic anti-pry shell structure is provided that can leave obvious damage traces after the electricity meter is pried open.

[0004] Therefore, this utility model provides an ultrasonic anti-pry shell structure, including a base and a cover placed on top of the base. The base and the cover are ultrasonically welded together. The cover and / or the base are provided with an extension groove that prevents breakage when an external tool pries the shell.

[0005] Furthermore: an extension plate is provided at the position where the cover and the base are fastened, the extension groove is provided at the extension plate, and a wrapping plate is provided on the base to wrap around the extension plate, and a groove for the extension plate to be embedded is formed in the wrapping plate.

[0006] Furthermore, the extending groove is located on both sides of the extending plate near the end, and the extending groove extends from both sides of the extending plate toward the middle of the extending plate.

[0007] Furthermore, the extended groove is configured in the form of an arc, triangle, or rectangle.

[0008] Furthermore, the extension plate is provided with an ultrasonic welding surface at the contact position with the base for fixing and connecting the base and the cover.

[0009] Furthermore: a viewing window is provided on the cover, a terminal cover is provided below the cover, and a lead-sealing hole is provided between the extension plate and the terminal cover for an external lead-sealing wire to pass through.

[0010] Furthermore: the ultrasonic welding surface includes a first welding surface and a second welding surface, and the first welding surface and / or the second welding surface are provided with an extension strip that can be inserted into the base.

[0011] Furthermore: the base is provided with a first contact surface that abuts against the first welding surface and a second contact surface that abuts against the second welding surface, the depth of the second contact surface being deeper than the depth of the first contact surface, and the second welding surface and the second contact surface being disposed at the connection between the extension plate and the wrapping plate.

[0012] Furthermore: the extension strip is located on the side where the second welding surface contacts the second contact surface, and the cross-section of the extension strip is an inverted triangle.

[0013] Furthermore, the distance from the bottom of the extended groove to the outer side of the extended plate is 0.4mm-0.8mm.

[0014] The technical solution of this utility model has the following advantages: 1. The present invention provides an ultrasonic anti-tilting shell structure, wherein an extended groove is provided on the base or cover or the base and cover. The extended groove forms a weak point. When someone pries it in between the cover and the base, the extended groove is relatively weak. Therefore, when the cover is pried and deformed, the extended groove is easy to break.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example This embodiment provides an ultrasonic anti-pry shell structure, including a base 1 and a cover 2 covering the base 1. The base 1 and the cover 2 are ultrasonically welded together. The cover 2 and / or the base 1 are provided with an extension groove 3 that will break when an external tool pries the shell.

[0024] The specific improvements mentioned above are as follows: Figure 1 , Figure 2 , Figure 3 , Figure 7 as well as Figure 8 Compared to existing technologies, the base 1 or cover 2 or both base 1 and cover 2 are provided with an extended groove 3. The extended groove 3 forms a weak point. When someone pries it between cover 2 and base 1, the extended groove 3 is relatively weak. Therefore, when cover 2 is pried and deformed, the extended groove 3 is easy to break. After the cover 2 breaks, it is not easy to restore it, and it will leave traces of damage. This allows maintenance or repair personnel to know whether the electricity meter has been pried, thus achieving the effect of preventing electricity theft.

[0025] Based on the above embodiments: an extension plate 4 is provided at the position where the cover 2 and the base 1 are fastened, an extension groove 3 is provided at the extension plate 4, and a wrapping plate 10 is provided on the base 1 to wrap around the extension plate 4, and a groove 101 for the extension plate 4 to be embedded is formed in the wrapping plate 10.

[0026] The specific improvements mentioned above are as follows: Figure 2 , Figure 4 Figure 9 as well as Figure 10 As shown, the base 1 and the cover 2 are fastened together. The cover 2 is provided with an extension plate 4 and an extension groove 3 is provided on the inner side wall of the extension plate 4. The base 1 is provided with a wrapping plate 10 that wraps the extension plate 4. The wrapping plate 10 is provided with a groove 101. When the base 1 and the cover 2 are fastened together, the extension plate 4 will be embedded in the groove 101. When it is necessary to pry open the cover 2, the tool can only be inserted into the gap between the extension plate 4 and the wrapping plate 10. This will cause the extension groove 3 of the extension plate 4 to break, thus forming a damage mark.

[0027] Based on the above embodiments: the extension groove 3 is located on both sides of the extension plate 4 near the end, and the extension groove 3 extends from both sides of the extension plate 4 toward the middle position of the extension plate 4.

[0028] Based on the above embodiments: the extended groove 3 is arranged in an arc shape, a triangle or a rectangle.

[0029] The specific improvement is as follows: those skilled in the art can freely set the shape of the extension groove 3 according to the specific situation. Whether it is an arc, a triangle or a rectangle, it can make the extension plate 4 break when it is pried. Preferably, the shape of the extension groove 3 is set to an arc, so that when the extension plate 4 is damaged, the crack can extend upward and increase visibility.

[0030] Based on the above embodiments: the extension plate 4 is provided with an ultrasonic welding surface 5 at the position where it contacts the base 1 for fixing and connecting the base 1 and the cover 2.

[0031] The specific improvements mentioned above are as follows: Figure 6 and Figure 7 As shown, the ultrasonic welding surface 5 effectively connects the base 1 and the cover 2, preventing external personnel from damaging the meter and stealing electricity.

[0032] Based on the above embodiments: a viewing window plate 8 is provided on the cover 2, a terminal cover 6 is provided below the cover 2, and a lead sealing hole 7 for external lead sealing wire to pass through is provided between the extension plate 4 and the terminal cover 6.

[0033] The specific improvements mentioned above are as follows: Figure 4 As shown, the window panel 8 can seal the cover 2, the terminal cover 6 can effectively protect the wiring, and the lead seal hole 7 allows the lead seal rope to pass through the lead seal hole 7, thus achieving a lead seal effect between the base 1 and the cover 2.

[0034] Based on the above embodiments: the ultrasonic welding surface 5 includes a first welding surface 51 and a second welding surface 52, and the first welding surface 51 and / or the second welding surface 52 are provided with an extension strip 53 that can be inserted into the base 1.

[0035] Based on the above embodiments: the base 1 is provided with a first contact surface 11 that abuts against the first welding surface 51 and a second contact surface 12 that abuts against the second welding surface 52. The depth of the second contact surface 12 is deeper than the depth of the first contact surface 11. The second welding surface 52 and the second contact surface 12 are located at the connection between the extension plate 4 and the wrapping plate 10.

[0036] Based on the above embodiments: the extension strip 53 is located on the side where the second welding surface 52 contacts the second contact surface 12, and the cross-section of the extension strip 53 is an inverted triangle.

[0037] The specific improvements mentioned above are as follows: Figures 2-7As shown, two welding surfaces are provided on the base 1 and the cover 2 (the first ultrasonic welding surface 5 is welded to the first contact surface 11, and the second ultrasonic welding surface 5 is welded to the second contact surface 12). The surface where the second ultrasonic welding surface 5 is welded to the second contact surface 12 is a deeper plane. When an external person uses a tool to pry open the electricity meter, the tool cannot reach the position of the second contact surface 12 and the second ultrasonic welding surface 5 to pry the deeper plane, thus effectively preventing damage.

[0038] Based on the above embodiments: the distance from the bottom of the extension groove 3 to the outer side of the extension plate 4 is 0.4mm-0.8mm.

[0039] The specific improvements mentioned above are as follows: the distance from the bottom of the extended groove 3 to the outer side of the extended plate 4 can be set to a minimum of 0.4mm and a maximum of 0.8mm.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
