Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The LED screen that Fig. 1 to Fig. 4 switches fast for the screen body printing opacity described in the utility model embodiment and non-transparency, it comprises casing 1, shadow shield 2 and knob assembly.Wherein, casing 1 is provided with pair of guide rails 11 and several first regularly arranged gate hole 12, and shadow shield 2 is arranged on guide rail 11, which is provided with second gate hole 21 that arrange corresponding to the first gate hole 12, knob assembly is arranged on shadow shield 2, and slides along guide rail 11 by rotarily driving shadow shield 2.
This knob assembly comprises knob 3, knob drain pan 4, knob base 5, adjusting slider 6 and a pair spring ripple pearl 7.Knob 3 and knob base 5 fixedly mount, knob drain pan 4 is folded between knob base 5 and knob 3, and knob base 5 and knob 3 can rotate relative to knob drain pan 4, adjusting slider 6 is fixed on shadow shield 2, which is provided with arc guide barrel 61, knob base 4 is provided with slide protrusion 53, and slide protrusion 53 is arranged in guide groove 61, and can move along guide groove 61.
Particularly, knob drain pan 4 is fixed on casing 1 by the screw hole 43 at its two ends, and its top is provided with through hole 41, and bottom is provided with a pair spacing preiection 42, for limiting the anglec of rotation of knob 3.Knob 3 is provided with protuberance 31 and a pair first circular holes 32, and knob base 5 is provided with patchhole 51, and protuberance 31 is rotatable to be passed through hole 41 and is arranged in the patchhole 51 on knob base 5.Be fixed installation by self-tapping screw (not shown) between knob 3 and knob base 5, adjusting slider 6 is also fixed on shadow shield 2 by self-tapping screw (not shown).The edge of knob base 5 is provided with a pair sector notch 52, and the spacing preiection 42 on knob drain pan 4 lays respectively in a pair sector notch 52, can limit the anglec of rotation of knob, and in the present embodiment, knob 3 rotates between 0 °-90 °.Knob base 5 is also provided with a pair second circular holes 54, spring ripple pearl 7 is interposed between knob 3 and knob base 5, and its two ends are arranged in the first circular hole 32 on knob 3 and the second circular hole 54 on knob base 5 respectively.Preferably, shadow shield 2, adjusting slider 6 and slide protrusion 53 are provided with a pair respectively.
As shown in Figure 3, when knob 3 is positioned at horizontal level, the second gate hole 21 on shadow shield 2 is just in time in the face of the first gate hole 12, and now, shadow shield 2 does not block the first gate hole 12, and LED screen is in light transmission state.Be rotated counterclockwise this knob 3, now, the slide protrusion 53 on knob base 5 slides along arc guide barrel 61, when knob 3 rotates to certain angle, slide protrusion 53 starts to drive guide groove 61 to rotate together, thus the shadow shield 2 be fixed on adjusting slider 6 is slided relative to casing 1.When knob 3 rotates to vertical position as shown in Figure 4, sector notch 52 on knob base 5 abuts with spacing preiection 42 and stops operating, now, second gate hole 21 leaves the position in the face of the first gate hole 12, shadow shield 2 covers the first gate hole 12, LED screen is in light tight state, and spring ripple pearl 7 can slight deformation cause producing the sensation blocked, and increases and uses feel.
The LED screen that screen body printing opacity described in the utility model and non-transparency switch fast, by arranging knob assembly and guide rail 11, can realize the quick switching of LED screen between printing opacity and light tight two states, and structure is simple, easy to operate.
The foregoing is only preferred embodiment of the present utility model; not in order to spacing the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
