The hinge rod 5 is provided with a connecting rod 7, a straight line at the axis of the connecting rod 7 is collinear with a straight line at the axis of the hinge rod 5, the end of the connecting rod 7 is perpendicular to the connecting rod 7 and is provided with a transmission rod 8, the fixing mechanism comprises a movable rail 9 arranged on the side wall of the shell 1, a T-shaped movable groove 10 is horizontally arranged in the middle of the movable rail 9, a movable block 11 is movably arranged in the movable groove 10 in a manner of being matched with the movable groove 10, a movable rod 12 is arranged on the movable block 11, a movable wheel 13 is arranged on the movable rod 12, an elastic part 14 is further arranged in the movable groove 10, one end of the elastic part 14 is connected to the inner wall of the movable groove 10, the other end of the elastic part is connected with the movable block 11, when the baffle 6 is positioned in the concave groove 2, the transmission rod 8 is separated from the movable wheel 13, when rotating articulated rod 5, the tip of transfer line 8 can movably contradict in the outer wall of activity wheel 13, and the drive the activity wheel 13 with the movable block 11 is movable, works as when baffle 6 is the level form, the tip of transfer line 8 contradicts in the downside of activity wheel 13.
The movable wheel 13 is rotatably connected to the movable rod 12. The end part, far away from the connecting rod 7, of the transmission rod 8 is rotatably provided with a driving wheel 15, and the driving wheel 15 can movably abut against the outer wall of the movable wheel 13.
According to the ammeter box structure convenient to read and operate, when an ammeter is reset or inserted, firstly, the baffle 6 is rotated, after the baffle is rotated to the horizontal position, the fixing mechanism fixes the angle of the hinge rod 5, and at the same time, the position of the baffle 6 is fixed, so that the baffle 6 can be released, and then the ammeter box structure can be inserted or a reset button can be pressed; the process can be completed by only one hand, so that the operation convenience is improved; while the shutter 6 remains horizontal throughout the process, it is also possible to prevent the shutter 6 from interfering with the reading of the data on the meter, making reading and operation simpler. When the card is inserted and drawn, the baffle 6 in the horizontal state can not act on the hand of an operator, and can not generate relative friction with the finger tip of the operator, so that the operation comfort level is higher.
When the baffle 6 is rotated, the baffle 6 drives the connecting rod 7 and the transmission rod 8 to rotate through the hinge rod 5, the transmission rod 8 enables the driving wheel 15 to move from a position far away from the movable wheel 13 to be abutted to the outer wall of the movable wheel 13 in the rotating process, the driving wheel 15 drives the movable wheel 13 to move along with the continuous rotation of the baffle 6, the driving wheel 15 drives the movable rod 12 and the movable block 11 to move, the movable block 11 can only move along the length direction of the movable groove 10 under the limiting effect of the movable groove 10, and meanwhile, the elastic part 14 (preferably, a spring in the embodiment) is compressed; the hinge rod 5 continues to rotate until the driving wheel 15 moves below the movable wheel 13, and the elastic piece 14 drives the movable wheel 13, the movable block 11 and the movable rod 12 to move to the initial position; after the baffle 6 is released, the movable wheel 13 plays a role in limiting the driving wheel 15 and also plays a role in limiting the baffle 6. When the baffle 6 is rotated into the concave groove 2, the baffle 6 is directly rotated downwards, the baffle 6 drives the movable wheel 13 to move again, and therefore the connecting rod 7 and the transmission rod 8 can normally rotate until the baffle 6 and the transmission rod 8 are in a vertical state.
In the process of rotating the baffle 6, the driving wheel 15 and the movable wheel 13 can rotate, so that sliding friction between the driving wheel and the movable wheel is prevented, the operation is more labor-saving, meanwhile, the loss between the structures of the fixing mechanism is reduced, and the service life is prolonged.
In a further embodiment, the movable rail 9 and the movable groove 10 are both inclined, the elastic element 14 is not arranged between the inner wall of the movable groove 10 and the movable block 11, and the movable wheel can have a tendency to move towards the bottom end of the movable rail under the action of gravity; when the baffle 6 is vertical, the movable wheel 13 is positioned at the bottom end of the movable rail 9, the baffle 6 rotates upwards, the driving wheel 15 abuts against the outer edge of the movable wheel 13 and drives the movable wheel 13 to move obliquely upwards, after the baffle 6 rotates to a horizontal state, the movable wheel 13 slides down to the bottom end of the movable rail 9 under the action of gravity, and the movable wheel 13 abuts against the driving wheel 15 to limit the driving wheel 15.
Example 2
The ammeter box structure convenient to read and operate is different from the first embodiment in that, as shown in the figure, the fixing mechanism comprises a connecting piece 16 arranged on the hinge rod 5, two sides of the end part of the connecting piece 16 far away from the hinge rod 5 are respectively provided with a rectangular box body I17 and a circular arc box body II 18, the box body I17 and the box body II 18 are both hollow, the box body I17 is communicated with the box body II 18, a movable fluid is arranged in the box body I17 and the box body II 18, the volume of the movable fluid is smaller than the total volume of the box body I17 and the box body II 18, a movable cover 19 used for moving the box body II 18 is arranged on the side wall of the shell 1, when the baffle 6 is positioned in the concave groove 2, the connecting piece 16 is vertical, and the movable fluid is positioned in the box body II 18, and the second box body 18 is positioned in the movable cover 19, when the baffle 6 is horizontal, the connecting piece 16 is horizontal, and the movable fluid is positioned in the first box body 17.
When the baffle 6 is in the concave groove 2, the connecting piece 16 is in a vertical state, meanwhile, the first box body 17 and the second box body 18 are positioned on two sides of the connecting piece 16, and at the moment, the movable fluid (preferably water in the embodiment) is positioned in the second box body 18 in the shape of the circular arc, so that the second box body 18 can apply a rotating trend to the connecting piece 16 and the baffle 6, but the baffle 6 cannot rotate continuously because the baffle 6 is limited by the inner wall of the concave groove 2, namely, the position of the baffle 6 can be stably maintained. When the baffle 6 is rotated upwards until the baffle 6 is horizontal, the connecting piece 16 is also horizontal, and the box body 17 is vertical, and during the rotation, the movable fluid flows from the box body two 18 to the box body one 17, so that the position of the baffle 6 can be kept by the weight of the movable fluid in the box body one 17 (the baffle 6 is a thin plastic plate, so that the weight is light); when the baffle 6 is rotated into the concave groove 2, only the baffle 6 needs to be rotated downwards, finally the second box body 18 is positioned in the movable cover 19, and the movable fluid also flows into the second box body 18, so that the operation is simple and convenient. The baffle 6 is long, so the operation of rotating the baffle 6 is labor-saving and convenient.
