Description

Technical Field

[0001] The utility model relates to the technical field of electric energy metering boxes, in particular to an outlet structure of an electric energy metering box. Background Art

[0002] An electric energy meter box is a device for measuring electric energy. For example, the electric energy meter box with publication number CN212849478U includes a box body, a box door, a vacuum circuit breaker and a lightning arrester. The vacuum circuit breaker is fixedly installed on the top of the box body, and the lightning arrester is fixedly installed equidistantly near the vacuum circuit breaker on the top of the box body. Two box doors are symmetrically rotatably connected to one side of the box body. The two sides of the box body away from the box doors are provided with sliding shielding mechanisms that can be pushed and pulled to protect the surface of the box body, and the side of the sliding shielding mechanism close to the box door is symmetrically provided with locking mechanisms that can be locked and connected. When the device protects the box body, the push-pull handle is pulled to move the shielding L-shaped plate along the slide rail to the front surface of the box body.

[0003] Although the utility model realizes the protection and sealing of the box body when it is not necessary to open the box body under the cooperation of the sliding shielding mechanism and the locking mechanism, effectively preventing its surface from being corroded, and effectively realizing the protection of the outer wall of the metering box body from being corroded and damaged, but in the specific use process, it does not have an outlet structure, so it is impossible to manage the connecting wires, resulting in the connecting wires being entangled in a complex manner and affecting its maintenance efficiency. In addition, when the outlet hole for the outlet is opened on the electric energy meter box, the inside of the electric energy meter box is connected to the outside, which affects its sealing, so that dust and insects can enter the electric energy meter box through the outlet hole and cause pollution. In view of this, we propose an outlet structure for an electric energy meter box. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0030] A wire outlet structure of an electric energy meter box, comprising a chassis body 1 with a wire outlet hole 13 formed on the outer wall, a support plate 12 formed on the outer wall of the chassis body 1 and below the wire outlet hole 13, a connection block 3 formed above the support plate 12, a cylindrical groove communicating with the outside formed at the center of the connection block 3, a bolt 31 for limiting the position of a connection line formed on the top of the connection block 3, a screw end of the bolt 31 passing through the outer wall of the connection block 3 and communicating with the inside of the cylindrical groove, so that the screw end of the bolt 31 can abut against the outside of the connection line to fix the position of the connection line, and a protective shell 32 for protecting the end of the connection line formed on the side of the connection block 3 away from the chassis body 1;

[0031] It also includes a positioning assembly for limiting the position of the connection block 3, the positioning assembly includes fixed blocks 4 symmetrically distributed on both sides of the connection block 3 and fixedly connected to the outer wall of the chassis body 1, the center of the fixed block 4 is slidably connected with a columnar rod 41 plugged with the side wall of the connection block 3, the end of the columnar rod 41 away from the connection block 3 passes through the corresponding fixed block 4 and is provided with a push-pull block 411, and a telescopic spring 42 is provided between the push-pull block 411 and the corresponding fixed block 4;

[0032] Furthermore, the telescopic spring 42 is sleeved on the outside of the corresponding cylindrical rod 41, so that the deformation trajectory of the telescopic spring 42 is limited by the cylindrical rod 41 to prevent the telescopic spring 42 from being lateral during the deformation process. In addition, when the telescopic spring 42 is in a normal supporting state, the end of the cylindrical rod 41 away from the fixed block 4 is immersed in the positioning groove provided on the side wall of the corresponding connecting block 3, so that the connecting block 3 is restricted;

[0033] The connecting block 3 is slidably connected to the support plate 12 through the moving block 35. A moving groove 121 slidably connected to the moving block 35 is provided on the top of the support plate 12. One end of the moving groove 121 is communicated with the outside, so that the moving block 35 can be pulled out from the moving groove 121. The connecting block 3 is plugged and fixed to the chassis body 1 through the positioning shaft 33, so that the connecting block 3 and the chassis body 1 can be disassembled.

[0034] As a preferred embodiment of the present invention, an adsorption magnetic block 34 is embedded on one side of the connecting block 3 close to the chassis body 1 and close to the edge position, and a metal embedded block 14 adsorbed and matched with the adsorption magnetic block 34 is embedded on the outer wall of the chassis body 1. The adsorption and fixation of the adsorption magnetic block 34 and the metal embedded block 14 are used to enhance the fit and stability between the connecting block 3 and the chassis body 1.

[0035] As a preferred embodiment of the present invention, a rectangular block 11 is provided on the inner wall of the chassis body 1 and on one side of the wire outlet hole 13, and a rotating shaft 2 is provided between the rectangular block 11 and the inner wall of the chassis body 1, and the end of the rotating shaft 2 is connected to the inner wall of the corresponding rectangular block 11 and the chassis body 1 through a bearing, and a winding spring 21 for winding up the connecting wire is provided on the outer wall of the rotating shaft 2. During use, the energy storage and release of the winding spring 21 are utilized to realize automatic retraction and release of the cable. Specifically, when the connecting wire is pulled out, the winding spring 21 is tightened to store potential energy. When the external force is removed, the winding spring 21 can automatically reel in the connecting wire when the potential energy is released.

[0036] When the outlet structure of the electric energy meter box of the utility model is used, one end of the power line is passed through the outlet hole 13 and the center of the corresponding connecting block 3 and extended to the side of the connecting block 3 away from the chassis body 1, and then the corresponding bolt 31 is tightened so that the end of the bolt 31 abuts against the outer wall of the connecting line to limit the position of the connecting line, and then the protective shell 32 is threadedly connected to the connecting block 3, so that the end of the connecting line extending to the outside can be received in the protective shell 32 for protection, and at the same time, the gap between the outer wall of the connecting line and the inner wall of the cylindrical groove can be covered to prevent dust and insects from entering the gap between the connecting line and the inner wall of the cylindrical groove;

[0037] By pulling the push-pull block 411 to move away from the connecting block 3, the telescopic spring 42 is extended after being stressed. At this time, the columnar rod 41 moves synchronously with the push-pull block 411 and separates from the connecting block 3. At this time, the connecting block 3 loses the restriction of the columnar rod 41, and then pushes the connecting block 3 to move away from the chassis body 1, so that the adsorption magnetic block 34 is separated from the metal embedded block 14, and then the moving block 35 is pulled out from the corresponding moving groove 121, thereby realizing the separation of the connecting block 3 and the chassis body 1.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
