[0019] The following is combined with Figure 1-7 This application is described in further detail.

[0020] The embodiment of the present application discloses an electric energy meter box which is easy to maintain.

[0021] Reference Figure 1 The electric energy meter box comprises a box body 1, a plurality of box doors 2 hinged to the box body 1, a slide rail 3 is fixedly connected to both sides of the lower end of the box body 1, and a storage table 4 is slidably connected between the two slide rails 3. The storage table 4 is used for placing a notebook, so that the staff can record the situation of the electric energy meter box in time while observing it. It should be noted that a lock is set between the box door 2 and the box body 1, which needs to be opened by a key.

[0022] Reference Figure 1 , Figure 2The storage table 4 includes a table 41 for placing notebooks. A stopper 47 is fixedly connected to one side of the table 41 close to the door 2 to prevent the notebook from sliding off. A first connecting rod 42 and a second connecting rod 43 are connected to both sides of the table 41. The first connecting rod 42 is arranged at one end of the table 41 away from the door 2, and the second connecting rod 43 is arranged at one side of the first connecting rod 42 close to the door 2. The slide rail 3 includes a slide hole 31 for inserting the first connecting rod 42 and the second connecting rod 43. The slide hole 31 is divided into a horizontal section 311 and an inclined section 312. The inclined section 312 is arranged at one side of the horizontal section 311 close to the door 2, and the inclined section 312 is arranged to be inclined downward in a direction away from the horizontal section 311.

[0023] When the storage table 4 is pulled out, the first connecting rod 42 and the second connecting rod 43 first move a distance along the horizontal section 311, at which time the storage table 4 moves horizontally, and then the second connecting rod 43 enters the inclined section 312, at which time the storage table 4 gradually rotates to a tilted state, so that the notebook placed on the storage table 4 is at a comfortable writing angle.

[0024] Reference Figure 2 , Figure 3 In order to fix the storage table 4 after being pulled out, the lower side of the inclined section 312 away from the horizontal section 311 is connected to a positioning groove 32 for the second connecting rod 43 to rotate into, and the inner wall of the positioning groove 32 close to the inclined section 312 is fixedly connected to a round arched limiting protrusion 33.

[0025] Reference Figure 2 , Figure 4 The side of the table 41 is provided with a strip groove 411 for the second connecting rod 43 to be inserted, and the second connecting rod 43 can move along the strip groove 411 close to or away from the first connecting rod 42. The end of the second connecting rod 43 is fixedly connected to a limiting disk 431, and the strip groove 411 is connected to a limiting cavity 412 for the limiting disk 431 to be inserted and slided, and the limiting cavity 412 prevents the second connecting rod 43 from being separated from the table 41. A spring 46 is abutted between the inner wall of the end of the strip groove 411 away from the first connecting rod 42 and the second connecting rod 43, and the second connecting rod 43 is provided with a slot 432 for the spring 46 to be inserted, and the spring 46 applies a thrust to the second connecting rod 43.

[0026] When the second connecting rod 43 is in the inclined section 312, the axial centerline distance between the first connecting rod 42 and the second connecting rod 43 is A; when the second connecting rod 43 is in the positioning groove 32, the axial centerline distance between the first connecting rod 42 and the second connecting rod 43 is B; A is smaller than B.

[0027] When the second connecting rod 43 is not acted upon by an external force, it is pushed by the spring 46 and is located at one end of the strip groove 411 close to the first connecting rod 42, and the distance between the axis centers of the first connecting rod 42 and the second connecting rod 43 is at the shortest state. In this state, when the storage table 4 is pulled out to the end of the second connecting rod 43 at the inclined section 312, the second connecting rod 43 cannot naturally rotate around the first connecting rod 42 to enter the positioning groove 32 under the action of gravity, because the positioning groove 32 is arc-shaped and the radius is greater than A.

[0028] Therefore, when the storage platform 4 is pulled out to the point where the second connecting rod 43 is located at the end of the inclined section 312, it is necessary to manually apply downward pressure to the storage platform 4, and the second connecting rod 43 is squeezed by the limiting protrusion 33, the axial centerline spacing between the first connecting rod 42 and the second connecting rod 43 increases, and the spring 46 is further compressed, so that the second connecting rod 43 enters the positioning groove 32 to complete the positioning. At this time, there is a squeezing force between the second connecting rod 43 and the inner wall of the positioning groove 32, so the friction force is relatively large, and it is limited by the limiting protrusion 33, so the position of the storage platform 4 can remain stable.

[0029] Reference Figure 5 , Figure 6 , one of the box doors 2 is fixedly connected to a rotating shaft 5, and the lower end of the rotating shaft 5 is rotatably arranged in the box body 1. The lower end of the rotating shaft 5 is connected to a transmission member 6 located at the lower side of the box body 1, and both ends of the side of the table 41 away from the box door 2 are fixedly connected to connecting seats 44, and a transmission rod 45 is fixedly connected between the two connecting seats 44. The transmission member 6 includes a fixed bar 61 fixedly connected to the rotating shaft 5, and the end of the fixed bar 61 away from the rotating shaft 5 is rotatably connected to a rotating bar 62, and the end of the rotating bar 62 away from the fixed bar 61 is rotatably connected to a transmission ring 63, and the transmission rod 45 is movably arranged inside the transmission ring 63. The inner diameter of the transmission ring 63 is larger than the diameter of the transmission rod 45, so when the storage table 4 rotates around the first connecting rod 42, the transmission rod 45 can also rotate in the transmission ring 63.

[0030] The pulling and pulling of the storage table 4 is linked to the rotation of the box door 2. On the one hand, the storage table 4 can be automatically pulled out by opening the box door 2 during inspection, which is convenient to operate. On the other hand, non-staff members cannot open the box door 2 without a key, and naturally cannot pull out the storage table 4, thereby locking the storage table 4 and reducing malfunctions of the storage table 4 caused by human factors.

[0031] Reference Figure 5 , Figure 6A tension spring 64 is connected between the fixed bar 61 and the rotating bar 62, and the tension spring 64 provides a pulling force for the fixed bar 61 and the rotating bar 62 to move toward each other. When the door 2 is not opened, the angle between the fixed bar 61 and the rotating bar 62 is 90 degrees. On the one hand, it is adapted to the linkage structure of the storage table 4 and the door 2, which can increase the rotation angle of the door 2, and the storage table 4 does not need to move too long, and the spatial structure is more reasonable. On the other hand, when the door 2 is closed, the tension spring 64 provides a boost to facilitate the closing of the door 2. Reference Figure 1 , Figure 2 When the box door 2 is closed, the upper end of the baffle 47 abuts against the lower end of the box body 1, and the storage table 4 can also be used to store notebooks, meeting the needs of placing notebooks in the electric energy meter box in some areas. And when the box door 2 is not opened, the baffle 47 plays a sealing role to prevent outsiders from taking away the notebook.

[0032] Reference Figure 7 A heat insulating pad 7 is fixedly connected to the bottom of the box body 1, and the heat insulating pad 7 can reduce the influence of the heat inside the box body 1 on the aging of the notebook.

[0033] The implementation principle is: During inspection, the box door 2 is opened with the key, and the box door 2 drives the rotating shaft 5 to rotate, and then drives the storage table 4 to push outward through the transmission of the fixed bar 61, the rotating bar 62 and the transmission ring 63, until the second connecting rod 43 is at the end of the inclined section 312, and the storage table 4 is slightly pressed down by hand so that the second connecting rod 43 is stuck in the positioning groove 32, and finally the notebook is placed on the storage table 4, and records can be made while observing.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
