The wiring cover is secured to the housing with fasteners and serves to shield and protect the wiring ports inside the housing. Opening the wiring cover requires removing the fasteners first, which can easily lead to their loss. Summary of the Invention

[0003] The purpose of this application is to provide a smart energy meter calibration device with a novel wiring cover mounting structure, which aims to solve the technical problem that fasteners in the wiring cover of existing smart energy meter calibration devices are easily lost when opened.

[0004] To achieve the above objectives, this application adopts the following technical solution: A smart calibration device for an energy meter with a novel wiring cover mounting structure includes a housing and a wiring cover. The wiring cover has a mounting hole for fasteners to pass through, and the fastener has a limiting mechanism that can restrict the fastener to move axially within the mounting hole.

[0005] By adopting the technical solution of this application, the fastener is restricted within the mounting hole by a limiting mechanism, thus preventing the fastener from being lost when the wiring cover is opened.

[0006] Furthermore, a baffle is provided inside the mounting hole, and the fastener passes through the baffle.

[0007] Furthermore, the baffle is constructed as a circle arranged coaxially with the mounting hole.

[0008] Furthermore, the diameter of the central hole in the baffle is smaller than the outer diameter of the end of the fastener.

[0009] Furthermore, the limiting mechanism includes a limiting ring and a support plate. The limiting ring is sleeved on the outside of the fastener, and the support plate is slidably snapped onto the fastener. The limiting ring and the support plate are fixedly connected.

[0010] Furthermore, the outer diameter of the limiting ring is larger than the diameter of the central hole.

[0011] Furthermore, the fastener has a groove for inserting the support plate.

[0012] Furthermore, the groove extends along the axial direction of the fastener.

[0013] Furthermore, the groove is arranged radially along the fastener.

[0014] Furthermore, the groove extends radially through the fastener. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0017] The design concept of the smart calibration device for energy meters with a novel wiring cover mounting structure described in this application is as follows: Please see Figs. 1-3 A smart calibration device for an energy meter with a novel wiring cover mounting structure includes a housing 10 and a wiring cover 20. The wiring cover 20 is provided with a mounting hole 21 for fasteners 30 to pass through. The fasteners 30 are provided with a limiting mechanism 40, which can restrict the fasteners 30 to move axially within the mounting hole 21.

[0018] In the above structure, the fastener 30 is restricted within the mounting hole 21 by the limiting mechanism 40, which prevents the fastener 30 from being lost when the wiring cover 20 is opened.

[0019] An embodiment of the smart calibration device for energy meters with a novel wiring cover mounting structure described in this application: Please see Figs. 1-3 A smart calibration device for an energy meter with a novel wiring cover mounting structure includes a housing 10, a wiring cover 20, a fastener 30, and a limiting mechanism 40.

[0020] The wiring cover 20 is hinged to the housing 10 via a pivot 24. A mounting cylinder is fixed to the top surface of the wiring cover 20, defining a circular mounting hole 21. The axis of the mounting hole 21 is arranged perpendicular to the top surface of the wiring cover 20. A baffle 22 is fixed inside the mounting hole 21. The baffle 22 and the mounting cylinder are integrally formed. The baffle 22 is constructed to be circular and coaxial with the mounting hole 21. A circular central hole 23 is provided at the axis of the baffle 22 for the fastener 30 to pass through.

[0021] The fastener 30 is located inside the mounting hole 21. When the wiring cover 20 is closed, the fastener 30 can be screwed into the threaded hole inside the housing 10, thereby locking the wiring cover 20 in a closed state onto the housing 10.

[0022] The fastener 30 can be a bolt or a screw. The fastener 30 has an end 31. The outer diameter of the end 31 is larger than the outer diameter of the main body of the fastener 30. At the same time, the outer diameter of the end 31 is also larger than the diameter of the central hole 22, so that the end 31 is blocked above the baffle 21.

[0023] The fastener 30 has a groove 32 on its main body. The groove 32 extends along the axial direction of the fastener 30 and extends through the main body of the fastener 30, so that the groove 32 forms a rectangular groove structure with closed ends along the axial direction of the fastener 30.

[0024] The limiting mechanism 40 includes a limiting ring 41 and a support plate 42. The limiting ring 41 is sleeved on the outside of the main body of the fastener 30, and the support plate 42 passes through the inside of the slide groove 32. The support plate 42 can move along the axial direction of the fastener 30 inside the slide groove 32. The limiting ring 41 and the support plate 42 are fixedly connected.

[0025] The limiting mechanism 40 is arranged below the baffle 22, and the outer diameter of the limiting ring 41 is larger than the diameter of the central hole 23. The limiting mechanism 40 is used to prevent the fastener 30 from moving out of the central hole 23 from bottom to top.

[0026] The end 31 and the limiting mechanism 40 are respectively placed on the upper and lower sides of the baffle 22, thereby restricting the axial movement of the fastener 30 as a whole within the mounting hole 21, preventing the fastener from being lost when the wiring cover is opened.

[0027] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
