In the description of the embodiments of the present invention, it should be noted that, if the terms "upper", "lower", "inside", "outside", etc. are used for indicating the orientations or positional relationships based on the orientations or positional relationships shown in the drawings or the orientations or positional relationships that the products of the present invention usually place when using, the present invention is only used for convenience of description and simplification of the description, but does not indicate or imply that the devices or elements indicated must have specific orientations, be constructed in specific orientations, and operate, and thus, the present invention should not be construed as being limited. Furthermore, the appearances of the terms "first," "second," and the like in the description of the present invention are only used for distinguishing between the descriptions and are not intended to indicate or imply relative importance.
In the description of the embodiments of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in the attached drawings, the utility model comprises a frame body 1, a flashboard 2 and an electric screw rod 3, wherein the flashboard 2 is of an inverted trapezoidal structure with a wide top and a narrow bottom, an inverted trapezoidal slot matched with the flashboard 2 is arranged at the lower part of the frame body 1, inclined chamfer surfaces are milled at the two sides and the bottom of the flashboard 2 and the inverted trapezoidal slot, and a metal sealing plate 5 is arranged on the inclined chamfer surfaces;
the rear side of flashboard 2 is equipped with balancing pole 6, and is equipped with gyro wheel 7 respectively at the both ends of balancing pole 6, and the rear side of framework 1 is equipped with a pair of vertical guide way 8, and gyro wheel 7 rolls in vertical guide way 8, and electronic lead screw 3 is installed at framework 1 top to drive flashboard 2 reciprocates in framework 1.
A cross reinforcing rib plate 11 is arranged at the rear side of the flashboard 2, and the balance rod 6 is fixedly connected to the cross reinforcing rib plate 11.
The top of the flashboard 2 is provided with a guide plate 13, and the upper part of the frame body 1 is provided with a guide groove matched with the guide plate 13.
A mudguard 15 is arranged at the front side of the inverted trapezoidal slot of the frame body 1.
A hollow buffer plate 16 is provided on the front side of the shutter 2.
The working mode is as follows: the flashboard 2 is matched with the inclined chamfer surface on the inverted trapezoid slot of the frame body 1 after being put down, the two metal sealing plates 5 are sealed after being attached, because the flashboard 2 is inverted trapezoid, the two metal sealing plates 5 can be completely contacted only when the flashboard 2 and the frame body 1 are completely closed, the metal sealing plates 5 are not easy to wear,
