Embodiment
As shown in Figure 1, the utility model comprises casing, above-mentioned casing comprises chamber door 1, is positioned at the back up pad 2 of chamber door 1 both sides, with back up pad 2 vertically disposed base plates 3.Then at box inside; Be the back up pad 2 and base plate 3 surface attachment sound-absorbing material layers 101 of both sides; Described sound-absorbing material layer 101 is the three dimensional network structure system; The length-diameter ratio L/D of its grid is between 20 to 30, and promptly the length-diameter ratio of grid can be any ratio in 20,22,25,28,30.
On anti theft design, adopt embedded hinge to be connected between the chamber door 1 of the utility model and the back up pad 2 in left side.Chamber door 1 is provided with key sign indicating number tapered end 5, has major functions such as anti-drilling, pick-proof, anti-skilled unlocking, can prevent the illegal unlatching of chamber door and self-locking mechanism.Above-mentioned key sign indicating number tapered end 5 is a technology well known to those of ordinary skill in the art.In addition, can also be provided with observation panel 4 on the chamber door 1, be used to observe the reading of internal electric energy table.Be equipped with heat radiation window 6 on the back up pad 2 of chamber door 1 both sides, be used for the diffusing hot gas that removes box house.Box house, electric energy meter 7 are suspended on the round bar 10, and electric energy meter 7 is provided with handle, are used for electric energy meter 7 push-and-pull up or down, and the associating patching panel is positioned at the below of electric energy meter 7.
Like Fig. 3, shown in Figure 4, on supported on both sides plate 2, be equipped with cambered way, be provided with left chain wheel 10 in the left cambered way 8, be provided with right pulley 11 in the right cambered way 9, about two pulleys be connected through round bar 12, round bar 12 welds together with removable top cover 17.Like this, drive the motion of round bar 10 by the motion of pulley.The middle part of round bar 10 is fixedly connected with drive link 13; The left end of drive link 13 and left connecting link 14 are hinged, and the right-hand member of drive link 13 and right connecting link 15 are hinged, and left connecting link 14 all is hinged with back up pad 2 with right connecting link 15; Above-mentioned hinged place is turning joint; Be provided with left air spring 16 in addition at the middle part of left connecting link 14, left air spring 14 1 ends and left connecting link 14 are hinged, and its other end is hinged on the back up pad 2 in left side; Right connecting link 15 middle parts are provided with right air spring 17, and right air spring 17 1 ends and right connecting link 15 are hinged, and its other end is hinged on the back up pad 2 on right side, and left and right sides air spring is used for alleviating slideway and reaches the dynamics of stroke from the bottom to top from top to bottom.
The principle of work of the utility model is: when needing maintenance electric energy meter 7, upwards promote the handle of setting on the electric energy meter 7, thereby round bar 10 is moved upward.Because round bar 10 is fixedly connected with removable top cover 18, so in the process that round bar 10 moves upward, removable top cover 18 is also opened thereupon.On the other hand, round bar 10 also is fixedly connected with drive link 13, moves upward thereby drive drive link 13, makes drive link 13 lifted the upright position by horizontal level.Thus, the travel path of round bar 10 and drive link 13 is circular arc, so be the circular arc slideway at the slideway of back up pad 2 both sides.Simultaneously because the existence of left and right sides air spring; In pulling round bar 10, certain buffer action is arranged; Prevented effectively to the strenuous vibration of electric energy meter and the destruction of bringing that in addition, air spring also can play certain supporting role when round bar 10 moves to ways-end.When round bar 10 moved to ways-end, the electric energy meter 7 that hangs on the round bar 10 also was drawn out ammeter box, and this moment, the electric wire of electric energy meter 7 back also came out, and the staff can overhaul electric energy meter 7.After maintenance finishes, promote drive link 13 electric energy meter 7 is pushed back to the origin-location.After pushing back the origin-location, the electric wire of electric energy meter 7 and associating terminal box back thereof is hidden in ammeter box inside, forms self-locking, when opening chamber door 1, also no longer is exposed to the outside, thereby reaches anti-electricity-theft purpose.
