Abstract
The utility model relates to a cumulative time meter display screen damage preventing structure which is characterized in that a cumulative time meter outer shell and a cumulative time meter circuit board arranged in the outer shell are included, a display screen is arranged on the a cumulative time meter circuit board, and a transparent plastic hood for covering the display screen is arranged between the display screen and a display window of the upper portion of the cumulative time meter outer shell. The cumulative time meter display screen damage preventing structure has the advantages that the structure is simple, the design is reasonable, through the transparent plastic hood, external acting force can not be directly exerted on the display screen, and damage of the display screen is avoided.
Description
Technical field:
The utility model relates to a kind of cumulative timer display screen damage-preventing structure.
Background technology:
The cumulative timer product is widely used in the fields such as building, communication, electric power, electronics, chemical industry, machinery, existing cumulative timer normally has display window on shell, display screen is directly arranged in this display window, outside beyond doubt display screen being exposed to, when the effect that external force is arranged, display screen and leg thereof easily damage.
Summary of the invention:
The purpose of this utility model is to provide a kind of cumulative timer display screen damage-preventing structure, and this cumulative timer display screen damage-preventing structure is reasonable in design, is conducive to prevent the damage of display screen.
The utility model is achieved through the following technical solutions:
The utility model cumulative timer display screen damage-preventing structure, it is characterized in that: comprise the cumulative timer shell and establish cumulative timer circuit board in the enclosure, described cumulative timer circuit board is provided with display screen, between the display window of described display screen and cumulative timer shell upper, is provided with for covering the blister pack of display screen.
Above-mentioned blister pack is rectangular parallelepiped, and the outer shape of this rectangular parallelepiped and cumulative timer outer casing inner wall shape match.
Above-mentioned blister pack upper surface is provided with the convex surface that the shape with display window matches.
The utility model advantage: simple in structure, reasonable in design, by being provided with blister pack, thereby external influence power can directly not acted on display screen, avoided the damage of display screen.
The accompanying drawing explanation:
Fig. 1 is stereographic map of the present utility model;
Fig. 2 is the utility model sectional view (removing shell 1);
Fig. 3 is side view of the present utility model.
Embodiment:
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below:
The utility model cumulative timer display screen damage-preventing structure, comprise cumulative timer shell 1 and establish cumulative timer circuit board 2 in the enclosure, described cumulative timer circuit board 2 is provided with display screen 3, between the display window 4 on described display screen 3 and cumulative timer shell 1 top, is provided with the blister pack 5 for covering display screen.By this blister pack, extraneous acting force is directly delivered on circuit board 2, and can act on display screen, avoided the damage of display screen.
For reasonable in design, location is reliable, and above-mentioned blister pack is rectangular parallelepiped, and the outer shape of this rectangular parallelepiped and cumulative timer outer casing inner wall shape match.
Reliable for positioning stablity, above-mentioned blister pack upper surface is provided with the convex surface 6 that the shape with display window matches, and this convex surface is spacing in this display window, has prevented the vibration of display screen.
Above-mentioned cumulative timer shell 1 upper and lower surface is provided with elastic card 7, with for clip in the installation window of equipment.
Above-mentioned elastic card 7 is U-shaped, and elastic card 7 rear ends are screwed onto cumulative timer shell rear portion by bolt 8.
Be welded with two L-type pins 9 on above-mentioned cumulative timer circuit board, this two pins one end is welded on the cumulative timer circuit board, and the other end stretches out outside the cumulative timer shell, and this end is locked on the cumulative timer shell with screw 10 and compressing tablet 11.
The utility model advantage: simple in structure, reasonable in design, by being provided with blister pack, thereby external influence power can directly not acted on display screen, avoided the damage of display screen.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
