Description

Technical Field

[0001] The utility model belongs to the technical field of meter boxes, and in particular relates to a rotary cover structure of a meter box. Background Art

[0002] The meter box is used to install the circuit board, meter and other components of the meter. Most of the meter boxes on the market are equipped with a rotating cover to facilitate opening the rotating cover to observe the data on the meter box. Figure 1 As shown, the connection method of the meter box and the flap on the market is mostly that the structure on the box cover is a concave point, and the structure on the flap is a convex point, and the convex point on the flap is inserted into the concave point of the box cover to achieve the purpose of rotating the flap. The disadvantages of this connection method are: (1) when the convex point and the concave point are installed, the meter box or the flap needs to be deformed before it can be installed. When the convex point is long, it is easy to cause the flap to be damaged. At the same time, since there is no guiding structure, it is not conducive to the alignment of the convex point and the concave point, which affects the efficiency of disassembly and assembly; (2) in order to facilitate the installation of the flap, the gap between the flap and the box cover is generally reserved. The matching gap between the parts is large, the waterproof effect is reduced, and the aesthetics of the product is reduced. Summary of the invention

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] A rotary flap structure of a meter box comprises a rotating shaft 2 for connecting a rotary flap 1 and a meter box 5 and a rotating shaft groove 3 for connecting the rotating shaft 2. An opening 4 is provided on one side of the rotating shaft groove 3. The rotating shaft 2 is installed into the rotating shaft groove 3 through the opening 4, so as to ensure that the meter box 5 and the rotary flap 1 do not deform when they are assembled, thereby improving the assembly convenience of the meter box 5 and the rotary flap 1, and at the same time reducing the size of the gap between the meter box 5 and the rotary flap 1, thereby improving the waterproof effect of the rotary flap 1.

[0023] The connection relationship between the shaft groove 3 and the shaft 2 is a clearance fit or an overfit, that is, the inner diameter of the shaft groove 3 is substantially consistent with the diameter of the shaft 2, thereby ensuring the connection stability between the rotating flap 1 and the meter box 5 and preventing the rotating flap 1 from shaking relative to the meter box 5.

[0024] To prevent the shaft 2 from sliding out of the shaft slot 3 from the opening 4 during the flipping of the rotating flip cover 1, the width of the opening 4 is smaller than the diameter of the shaft 2. Preferably, the width of the opening 4 is 0.9 times the inner diameter of the shaft slot 3, to ensure that when the shaft 2 is installed into the shaft slot 3 through the opening 4, the opening 4 can be opened, but the opening amount of the opening 4 will not cause damage to the shaft slot 3.

[0025] A guide opening 13 connected to the opening 4 is provided at the end of the opening 4 . The guide opening 13 is in a closed shape. The guide opening 13 increases the width of the outer end of the opening 4 , thereby facilitating guiding the rotating shaft 2 into the opening 4 .

[0026] The opening 4 is tilted relative to the end face of the rotating flap 1. Preferably, the tilt angle between the axis of the opening 4 and the end face of the rotating flap 1 is 20°-40°, which prevents the opening 4 from being perpendicular or parallel to the end face of the meter box 5, and can further prevent the rotating flap 1 and the meter box 5 from separating.

[0027] A watch cover groove 6 for installing a rotating watch cover is provided in the watch box 5 , the rotating shaft 2 is connected to the inner wall of the watch cover groove 6 , and the rotating shaft groove 3 is arranged on the side wall of the rotating flip cover 1 .

[0028] The rotating flip cover 1 includes a cover end plate 8 and a cover side plate 9 connected to the inner end surface of the cover end plate 8 . The end of the cover side plate 9 is formed on a circular ring 14 , which surrounds the shaft groove 3 , and the opening 4 is arranged on the circular ring 14 .

[0029] In order to increase the strength of the ring 14, a recessed plate 10 connected to the cover side plate 9 is provided on the rotating flap 1. The recessed plate 10 is arranged on the inner side of the ring 14. At this time, the shaft groove 3 is located on the outer side of the recessed plate 10, which facilitates the connection between the shaft 2 and the shaft groove 3.

[0030] The watch cover side plate 9 is arranged on the inner side of the edge of the watch cover end plate 8 to form a step between the watch cover side plate 9 and the watch cover end plate 8; a raised surface 11 is provided on the inner wall of the watch cover groove 6, and the raised surface 11 is adapted to the step, that is, the step is buckled on the side wall of the raised surface 11, thereby increasing the waterproofness of the rotating flip cover 1 covered on the watch box 5.

[0031] The bottom of the rotating shaft 2 is transitionally connected to the inner wall of the meter cover groove 6 through the arc surface 7. The arrangement of the arc surface 7 increases the connection strength between the rotating shaft 2 and the meter box 5.

[0032] To prevent the arc surface 7 from interfering with the end surface of the shaft groove 3 , a shaft groove 12 is provided on the convex surface 11 , the shaft 2 is arranged in the shaft groove 12 , and the height of the arc surface 7 is less than or equal to the thickness of the convex surface 11 .

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0034] Although this article uses more terms corresponding to the figure marks in the figures, it does not exclude the possibility of using other terms; these terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
