DETAILED DESCRIPTION

[0023] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] Example:

[0025] like Figures 1 to 6As shown, the utility model discloses a portable electric energy meter box, including a box body 11, and a mounting bracket 12 is detachably provided on the rear side wall of the box body 11, wherein the box body 11 is responsible for the main functions of the electric energy meter box for installing the electric meter, etc., and the mounting bracket 12 is an additional structure on the electric energy meter box, and the mounting bracket 12 is used for installation on the wall.

[0026] The interior of the mounting frame 12 is provided with a receiving cavity 121, and a support plate 13 for placing the box body 11 is fixedly provided at its bottom. At the same time, an insertion rod 21 is provided at the front end of the mounting frame 12 for sliding up and down, and a limit plate 22 is fixedly provided at the front end of the insertion rod 21. Correspondingly, a through slot 111 and a limit slot 112 are provided on the rear side wall of the box body 11. In this structure, the limit slot 112 extends in the up and down direction and one end is connected to the through slot 111. The insertion rod 21 is slidably provided between the through slot 111 and the limit slot 112. In this structure, the width of the limit slot 112 is smaller than the width of the through slot 111. The through slot 111 is used for the limiting plate 22 to enter the interior of the box body 11, and the limiting slot 112 is used to prevent the limiting plate 22 from exiting from the limiting slot 112. When the box body 11 moves on the support plate 13 until the limiting plate 22 enters the interior of the box body 11 from the through slot 111, the insertion rod 21 slides to the limiting slot 112, so that the limiting plate 22 is abutted against the rear side wall of the box body 11 inside the box body 11, thereby fixing the box body 11 to the mounting bracket 12.

[0027] An operating rod 23 is provided in the mounting frame 12, and one end of the operating rod 23 is slidingly set in the accommodating cavity 121. At the same time, the other end of the operating rod 23 extends in the left and right directions and passes through the accommodating cavity 121 to allow people to move it left and right. In this structure, the operating rod 23 is linked with the insertion rod 21. The operating rod 23 adjusts the up and down height of the insertion rod 21 by changing its own left and right positions. In addition, a positioning mechanism for limiting the sliding state of the operating rod 23 is provided on the mounting frame 12, which is used to position the left and right positions of the operating rod 23.

[0028] Furthermore, a first sliding plate 24 is provided in the accommodating cavity 121 for sliding left and right, and a second sliding plate 25 is provided for sliding up and down. In this structure, the first sliding plate 24 and the second sliding plate 25 are in a sliding connection relationship and are arranged in linkage with each other. At the same time, the first sliding plate 24 is connected to the operating rod 23 and slides left and right synchronously with the operating rod 23, while the rear end of the insertion rod 21 passes into the accommodating cavity 121 and is fixedly connected to the second sliding plate 25. Correspondingly, a movable groove 122 is provided on the side wall of the mounting frame 12 for the insertion rod 21 to slide up and down.

[0029] Furthermore, a slide groove 26 is formed on the first sliding plate 24, and correspondingly, a slider 27 is fixedly provided on the second sliding plate 25. The slider 27 is slidably disposed within the slide groove 26, and the slide groove 26 is obliquely disposed on the first sliding plate 24. In the above structure, since the first sliding plate 24 can only slide left and right, and the second sliding plate 24 can only slide up and down, when the first sliding plate 24 slides left and right, the slide groove 26 is inclined, so that the slider 27 is moved to different heights by the slide groove 26 as the first sliding plate 24 slides, thereby achieving the height adjustment of the second sliding plate 25.

[0030] Further, such as Figure 2 and Figure 3 As shown, the first operating rod 23 is horizontally arranged in the accommodating cavity 121 and is rotatably connected to the first sliding plate 24. At the same time, a through-hole 123 is opened on the side wall of the mounting frame 12 for the end of the first operating rod 23 to pass through. In addition, the positioning mechanism specifically includes a block 231 arranged on the side wall of the operating rod 23, and the block 231 is close to the end of the operating rod 23 located at the through-hole 123. At the same time, a first card groove 1 is provided between the side wall of the through-hole 123 and the inner side wall of the accommodating cavity 121 corresponding to the block 231. 24 and the second card slot 125, the first card slot 124 and the second card slot 125 are distributed on the side wall of the through-opening 123 at intervals along the circumferential direction, and the distance from the left end to the right end of the second card slot 125 is greater than the distance from the left end to the right end of the first card slot 124. Finally, an elastic pusher 126 is also provided in the accommodating cavity 121, and the elastic pusher 126 is set on the end of the operating rod 23 away from the block 231. In this structure, the elastic pusher 126 is used to push the operating rod 23 toward the through-opening 123.

[0031] In the above structure, when the left and right positions of the operating rod 23 need to be changed, it is only necessary to swap the card block 231 from the first card slot 124 to the second card slot 125 or swap the card block 231 from the second card slot 125 to the first card slot 124. Figure 3 When the locking plate 231 is in the first slot 124, the locking plate 22 is in the position limiting position against the box body 11. If the locking plate 22 is to be withdrawn from the through slot 111, the operating rod 23 can be pushed into the accommodating cavity 121 to withdraw the locking block 231 from the first slot 124. Then, the operating rod 23 can be rotated to align the locking block 231 with the second slot 125. At this time, the operating rod 23 is released, and the elastic pushing member 126 pushes the operating rod 23 again, so that the left and right positions of the operating rod 23 can be different from the previous static state. In this way, the left and right positions of the operating rod 23 can be changed, and the upper and lower positions of the limiting plate 22 can be adjusted accordingly.

[0032] Furthermore, a protrusion 116 is provided at the lower end of the box body 11, and a positioning groove 131 for the protrusion 116 to slide back and forth is provided on the upper end surface of the support plate 13 corresponding to the protrusion 116. The specific setting scheme of the protrusion 116 is: a sliding warehouse 114 is provided in the box body 11. At the same time, a movable opening 113 connected to the sliding warehouse 114 is provided at the bottom of the box body 11. In this structure, the upper end of the protrusion 116 is slidably connected to the sliding warehouse 114 and the lower end extends to the movable opening 113. At the same time, an elastic supporting member 115 is provided in the sliding warehouse 114 for pushing the protrusion 116 downward out of the movable opening 113.

[0033] This structure is mainly to facilitate the alignment of the through slot 111 at the rear of the box body 11 with the limit plate 22, so that when the box body 11 moves backward on the support plate 13, the limit plate 22 can directly enter the interior of the box body 11 through the through slot 111, making it convenient for the operating rod 23 to directly drive the second sliding plate 25 to move up and down.

[0034] The elastic resisting member 115 and the elastic pushing member 126 are both springs.

[0035] In addition, in the above structure, after the elastic pushing member 126 pushes the block 231 into the first slot 124, there is a certain distance between the block 231 and the end of the limiting slot 112 away from the through slot 111 and the end of the movable slot 122. In the process of the block 231 exiting the first slot 124, the distance is used to provide sliding space for the insertion rod 21.
