Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1, an intelligent electric meter, including the box 1 that is the cavity form, 1 side opening of box sets up, and the ammeter is equipped in box 1 through the opening side, and 1 opening side of box is provided with chamber door 2 through the hinge is articulated, sets up an observation window 3 that is rectangular form and is used for observing 1 inside of box on chamber door 2. 2 lateral walls of chamber door and the position that is close to 3 both sides angles departments of rectangle observation window are provided with two connecting blocks 6, be provided with connecting axle 4 between two connecting blocks 6, fixed cover is equipped with the window lid 5 that is used for sheltering from observation window 3 on the 4 lateral walls of connecting axle, the fixed gluing in border department that window lid 5 is close to one side of observation window 3 has sealing member 15, window lid 5 and connecting axle 4 syntropy rotate the setting, when connecting axle 4 rotates to window lid 5 and covers observation window 3, sealing member 15 laminates in 2 lateral walls of chamber door of 3 border departments of observation window. As shown in a combined view of fig. 4, the two ends of the connecting shaft 4 are integrally provided with a clamping block 8, the connecting block 6 is provided with a clamping groove 7 matched with the clamping block 8, and the connecting shaft 4 is clamped in the clamping groove 7 through the clamping block 8 and fixed on the outer side wall of the box body 1. The present embodiment preferably provides the seal 15 as a sealing strip.

As shown in fig. 2 and 3, the locking groove 7 includes a fixing portion 71 and a limiting portion 72, and the fixing portion 71 is rectangular and the limiting portion 72 is semicircular as viewed in a cross section along the length direction of the connecting shaft 4. When the window cover 5 rotates to be perpendicular to the outer side wall of the box door 2, the fixture block 8 enters the fixture groove 7 from the fixing portion 71 to the limiting portion 72, when the window cover 5 rotates to be parallel to the box door 2, the window cover 5 covers the observation window 3, and the fixture block 8 is located at the limiting portion 72 and abuts against the fixing portion 71. Preferably, the inner side wall of the limiting part 72 is provided with an elastic resetting piece 16, and the end surface of the latch 8 abuts against the elastic resetting piece 16. Set up elasticity piece 16 for the elastic rubber pad in this embodiment, the elastic rubber pad has deformability, does benefit to the rotation operation of fixture block 8 when spacing portion 72, and because of fixture block 8 both ends and elastic rubber pad butt, utilizes the elastic rubber pad to make fixture block 8 rotate fixed position when certain angle when rotating.

Wherein, the length of the connecting shaft 4 is larger than that of the window cover 5, and the window cover 5 is arranged along the length direction of the connecting shaft 4 in a sliding way. The outer side wall of the box door 2 and the position close to the corner of the rectangular observation window 3 are provided with limiting blocks 9, one side of each limiting block 9 close to the window cover 5 is provided with a groove 10, a first magnetic part (attached to the inner side wall of the groove 10 and not marked in the figure) is arranged in each groove 10, the side wall of the window cover 5 is fixedly provided with a second magnetic part 11 which is the same as the groove 10 in shape and size, and the close faces of the first magnetic part and the second magnetic part 11 are set to be different magnetic poles. When the window cover 5 slides to cover the observation window 3, the second magnetic member 11 is clamped in the groove 10, and the clamping block 8 abuts against the joint of the fixing portion 71 and the limiting portion 72. In the present embodiment, the first magnetic member and the second magnetic member 11 are configured as magnets.

Further, for better messenger's window lid 5 covers observation window 3, window lid 5 deviates from a corner department of connecting block 6 and stopper 9 and has seted up connecting hole 12, and through connection hole 12 is equipped with inserted bar 13 in connecting hole 12, and inserted bar 13 deviates from the fixed locating piece 14 that is provided with of one end of observation window 3, and when window lid 5 covered observation window 3, the lateral wall of inserted bar 13 and the 3 lateral walls butt of observation window. And when the window lid 5 covers the observation window 3, combine connecting block 6, stopper 9, inserted bar 13, can all fixed joint four angles of window lid 5 on the 1 lateral wall of box, prevent that the window lid 5 from sliding and can not cover the observation window 3 completely along 4 length direction of connecting axle.

It can be known from an overview that after the window cover 5 is worn, a recording person can hardly observe the internal condition of the box body 1 clearly through the window cover 5, and pushes the window cover 5 to move away from the limiting block 9 and then rotate the connecting shaft 4 until the window cover 5 is perpendicular to the box door 2, and then the clamping block 8 is moved out of the clamping groove 7 from the limiting portion 72 to the fixing portion 71 along the opening direction of the clamping groove 7, that is, the connecting shaft 4 and the window cover 5 are detached from the box door 2, a new or unworn window cover 5 is replaced, and then the connecting shaft 4 is rotated to make the window cover 5 cover the observation window 3. Through set up detachable window lid 5 structure on chamber door 2, and dismantle simple structure and easily operate, be convenient for the staff and change window lid 5 after window lid 5 is worn and torn to need not turn over window lid 5 and carry out the record when checking meter at every turn, improve work efficiency.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
