[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] Please refer to Figures 1-6 The present application provides a technical solution: a box group type electric energy metering box, comprising a box body 1 and a through hole 101 formed on the side wall of the box body 1, further comprising:

[0032] The ring 2 is fixedly connected to the inner side wall of the box body 1 and arranged around the through hole 101.

[0033] The outer circumferential surface of the ring 2 as the mounting surface of the packaging structure can provide rigid support for the radial sleeve connection of the flexible cover 3 and the elastic rubber ring 5.

[0034] The flexible cover 3 is detachably sleeved on the outer circumferential surface of the ring 2, and is used for shielding the through hole 101.

[0035] The elastic rubber ring 5 is detachably sleeved on the outer circumferential surface of the flexible cover 3, and is used for pressing and fixing the flexible cover 3 on the ring 2.

[0036] The elastic rubber ring 5 relies on its own contraction force to press the flexible cover 3 radially inward, so that it is tightly attached to the outer wall of the ring 2, thereby shielding the through hole 101 and preventing external dust from entering the box 1. This structure does not need to be bolted, is convenient for users to disassemble and assemble by hand, is convenient for opening the through hole 101 to pass the wire when the electric energy metering box is assembled and used, and is convenient for shielding the through hole 101 to restore the dustproof state when used independently. At the same time, the split structure is conducive to independent replacement of the flexible cover 3 and the elastic rubber ring 5, reduces the maintenance cost, and balances the shielding reliability, operation convenience and component maintainability.

[0037] The receiving member is arranged inside the box 1 and provides a fixed receiving position for the flexible cover 3 and the elastic rubber ring 5.

[0038] The hanging rod 8 axially limits the connection belt 4 and the rubber sleeve 6 through the blocking piece 801, realizes the suspension receiving of the flexible cover 3 and the elastic rubber ring 5, solves the problem that the metering box accessories are easy to lose and take time to find during expansion and reconstruction, and significantly improves the field operation efficiency.

[0039] Specifically, as shown in Figure 3 and Figure 4 , the inner port outer edge of the ring 2 is provided with a radial protruding anti-dropping flange 201, the elastic rubber ring 5 is sleeved on the outer peripheral surface of the flexible cover 3 through the anti-dropping flange 201, and the anti-dropping flange 201 forms a limiting cooperation with the elastic rubber ring 5 to limit the flexible cover 3 from sliding off the ring 2.

[0040] The flexible cover 3 is made of dustproof and breathable material.

[0041] By setting the radial protruding anti-dropping flange 201 on the inner port outer edge of the ring 2, the elastic rubber ring 5 forms an axial limiting cooperation, and the elastic rubber ring 5 needs to overcome the protruding resistance of the anti-dropping flange 201 to complete the sleeving. After installation, the inner diameter contraction force of the elastic rubber ring 5 presses the flexible cover 3 tightly on the outer peripheral surface of the ring 2, and the anti-dropping flange 201 forms a stop in the axial direction, effectively preventing the risk of sliding off. At the same time, the flexible cover 3 is made of dustproof and breathable material, which can not only block dust from entering, but also maintain the circulation of gas inside and outside the box 1, realizing the balance effect of heat dissipation and protection.

[0042] The material of the flexible cover 3 is selected to be a nylon dustproof mesh cloth.

[0043] Specifically, as shown in Figures 2-4 , the outer surface of the flexible cover 3 is sewn and connected with the connection belt 4, and the outer side of the elastic rubber ring 5 is connected with the rubber sleeve 6 through the connection belt 7.

[0044] The receiving member includes a hanging rod 8 fixed at the inner end of the box 1, and the hanging rod 8 is fixed with a blocking piece 801 that limits the sliding off of the connection belt 4 and the rubber sleeve 6.

[0045] The connecting band one 4 sewn on the outer surface of the flexible cover 3 and the rubber sleeve 6 connected with the connecting band two 7 on the outer side of the elastic rubber ring 5 jointly constitute a hanging structure, and the blocking piece 801 on the hanging rod 8 axially limits the connecting band one 4 and the rubber sleeve 6 to prevent slipping, thereby solving the problems of easy loss of accessories and time-consuming searching during expansion and reconstruction.

[0046] The connecting band one 4 and the connecting band two 7 are arranged in a radial direction of the hanging rod 8, and when the elastic rubber ring 5 is first separated from the outer side of the flexible cover 3, the connecting band two 7 is prevented from interfering with the connecting band one 4.

[0047] When the elastic rubber ring 5 is separated from the flexible cover 3, the connecting band one 4 does not interfere due to being arranged in different radial directions of the hanging rod 8, thereby ensuring the independence and smoothness of the dismounting action. The jamming problem caused by the stacking of the connecting bands is solved by simple spatial staggering, thereby improving the dismounting efficiency and operation reliability of the metering box in the expansion and maintenance scenarios.

[0048] Specifically, as shown in the figure, Figures 2-6 The inner end of the box body 1 is fixedly provided with a bending frame 9, and the bending frame 9 is used for clamping and storing the flexible cover 3 in a winding state.

[0049] The dismounted flexible cover 3 is directly clamped into the closed slot of the bending frame 9 after being wound, and the clamping force is generated by the elastic deformation of the bending structure itself, so that the compact storage without bundling is realized, which not only avoids the problem of scattering when the flexible material is hung, but also saves the space in the box.

[0050] The end of the bending frame 9 towards the box body 1 is in a closed structure; and the end of the bending frame 9 towards the box body 1 is formed with anti-skid lines 10.

[0051] The anti-skid lines 10 formed on the end surface increase the friction force with the surface of the flexible cover 3, and cooperates with the closed structure to significantly improve the stability and reliability of the storage.

[0052] The above description of the embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
