The two arc surface grooves 6 are symmetrically opened at the upper inner side of the concave cover 2 in the front and rear. The arc surface groove 6 in the front is slidably engaged with the spherical pin 8.
[0025] Please refer to Figure 2 ,Figure 3 and Figure 5 , in the illustration, the limiting mechanism includes two long slots 7 and two sliding blocks 9. The two sliding blocks 9 are symmetrically and fixedly connected to the rear edge of the two side walls of the shielding plate 3. The two long slots 7 are symmetrically arranged on the inner two side walls of the concave cover 2, and the two long slots 7 are respectively in sliding fit with the two sliding blocks 9.
[0026] Please refer to Figure 4 , in the illustration, the elastic member includes an annular plate 15. The annular plate 15 is fixedly sleeved on the outer wall of the insertion post 14, and the rear end of the annular plate 15 is in contact with the inner rear end of the cylinder body 4. A first spring 16 is fixedly connected between the front end of the annular plate 15 and the inner front end of the cylinder body 4. The first spring 16 is slidably sleeved on the outer wall of the insertion post 14.
[0027] Please refer to Figure 3 and Figure 4 , in the illustration, the pulling member includes a pulling block 11. The pulling block 11 is fixedly connected to the front end of the insertion post 14, and the rear end of the pulling block 11 is in contact with the front end of the cylinder body 4.
[0028] Please refer to Figure 3 , Figure 5 and Figure 7 , in the illustration, concave grooves 12 are symmetrically arranged at the two side edges of the upper end of the shielding plate 3. A set of anti-slip grooves 13 are arranged at the upper and lower ends of the rectangular plate 10 corresponding to the concave grooves 12; specifically, the arrangement of the concave grooves 12 facilitates pulling the rectangular plate 10 outwards, and the arrangement of the anti-slip grooves 13 can provide a certain anti-slip effect when pulling the rectangular plate 10.
[0029] Please refer to Figure 1 , Figure 3 and Figure 5 , in the illustration, a concave handle 5 is fixedly connected to the middle of the front end of the shielding plate 3.
[0030] Working principle: First, pull the concave handle 5 forward. The concave handle 5 will drive the shielding plate 3 to slide forward between the cabinet body 1 and the concave cover 2. The shielding plate 3 will drive the cylindrical groove 17 thereon and the spherical pin 8 on the cylindrical groove 17 to move forward. The spherical pin 8 will slide out of the arc-shaped groove 6 at the rear on the concave cover 2 (during this process, the second spring 19 between the spherical pin 8 and the cylindrical groove 17 will be compressed in the cylindrical groove 17). During the forward movement of the shielding plate 3, the two sliding blocks 9 on the shielding plate 3 will also slide forward in the corresponding long slots 7 on the concave cover 2. When the front end of the sliding block 9 is in contact with the inner front end of the long slot 7, under the action of the second spring 19, the spherical pin 8 will automatically reset and insert into the arc-shaped groove 6 at the front on the concave cover 2, and then the shielding plate 3 can maintain a fixed state after moving forward, as Figure 1As shown in the figure, at this time, the staff can stand under the baffle 3 to perform maintenance on the cabinet body 1, providing convenience for the staff to perform maintenance on the cabinet body 1 in harsh weather conditions such as high-temperature sun and rain and snow. When the baffle 3 is not needed, directly push the baffle 3 backward, and the baffle 3 can be stored between the cabinet body 1 and the concave cover 2, reducing the space occupation and improving the aesthetics at the same time, and the operation is simple.
[0031] When the shielding area of the baffle 3 cannot meet the actual shielding requirements, one of the pulling blocks 11 can be pulled forward. The pulling block 11 will drive the plug post 14 to slide forward in the corresponding baffle 3 and the inner wall of the cylinder body 4. The plug post 14 will drive the annular plate 15 thereon to slide forward in the cylinder body 4 (in this process, the first spring 16 between the annular plate 15 and the cylinder body 4 is squeezed on the outer wall of the plug post 14), and the plug post 14 will also slide outward in a jack 20 on the corresponding rectangular plate 10 and completely leave the jack 20. Subsequently, while keeping pulling the pulling block 11 without letting go, use the other hand to pull the rectangular plate 10 outward. The rectangular plate 10 can slide outward in the rectangular groove 18 on the corresponding baffle 3 until the rectangular plate 10 moves to the required position, then release the pulling block 11. Under the action of the first spring 16, the plug post 14 will automatically reset and insert into another jack 20 on the rectangular plate 10, and then the rectangular plate 10 can be kept in a fixed state after moving. Similarly, according to the reverse operation, the other rectangular plate 10 can be pulled out of the rectangular groove 18 on the corresponding baffle 3 and kept in a fixed state. At this time, the shielding area can be increased due to the two rectangular plates 10, so as to further meet the shielding requirements (it should be noted that whether it is necessary to pull out both rectangular plates 10 depends on the specific situation: for example, for sunshading, only the rectangular plate 10 on the side close to the sun needs to be pulled out).
[0032] It should be noted that this ring main unit can provide the function of shading and rain protection for the staff who perform maintenance on the cabinet body 1 in harsh weather conditions such as high-temperature sun and rain and snow, providing convenience for the staff to perform maintenance on the cabinet body 1. Not only the shielding effect is good, but also the shielding position and area can be adjusted according to the actual situation, and the use is flexible.
[0033] It also needs to be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
