Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in figs 1 to 6, goggles combined type discharging mechanism of the present invention comprises headpiece case, screening glass 12, goggles support arm 5, axle sleeve 3, regulating base board 10 and rotary handle 9.
Goggles support arm 5 is positioned at the both sides of screening glass 12, and screening glass 12 is hinged on headpiece case by goggles support arm 5.For composition is succinct, headpiece case is not shown.Goggles support arm 5 is provided with axle sleeve 3 and rotary handle 9, and rotary handle 9 is arranged in axle sleeve 3, is provided with Compress Spring 4 between rotary handle 9 and axle sleeve 3.Headpiece case is provided with regulating base board 10, and rotary handle 9 is provided with spacer pin 18, and regulating base board 10 is provided with multiple draw-in groove 19 coordinated with spacer pin 18.During pressing rotary handle 9, spring 4 is compressed, and spacer pin 18 departs from draw-in groove 19, screening glass 12 can rotate, and when unclamping rotary handle 9, spring 4 makes spacer pin 18 snap in draw-in groove 19, screening glass 12 cannot rotate, the fixed position that the different corresponding screening glasses of draw-in groove 19 12 is different.
When carrying out screening glass 12 folding and unfolding by rotary handle 9, pressing rotary handle 9, overcoming spring 4 power makes spacer pin 18 lift from draw-in groove 19, then rotary handle 9 is rotated, complete the folding and unfolding of screening glass 12, after unclamping rotary handle 9, spacer pin 18 is stuck in different draw-in grooves 19, completes the spacing fixing of diverse location.During ejection escape, the inertia force of seat fire overcomes the frictional force between spacer pin 18 and draw-in groove 19, falls in the next corresponding draw-in groove 19, make screening glass 12 be put into bottom from upper from the draw-in groove 19 of upper correspondence.Goggles combined type discharging mechanism of the present invention simple operation, uses flexibly and has the automatic lowering function of overload.
Further, rotary handle 9 is positioned at outside goggles support arm 5, makes structure compacter, convenient operation.
Further, the inner side of goggles support arm 5 is provided with installing plate 11, and installing plate 11 is fixed on headpiece case, and the outer ring 14 of regulating base board 10 is socketed in outside installing plate 11.The outer ring 14 of regulating base board 10 is provided with opening, and the outer ring 14 of opening both sides is locked by adjustment screw 15 and nut 17, is provided with spring washer 16 below adjustment screw 15.When unclamping adjustment screw 15, can rotate regulating base board 10, draw-in groove 19 is corresponding rotation also, achieves the fine setting of screening glass 12 fixed angle.
Further, connected by transition arc between multiple draw-in groove 19, smoothly transit, ensure that, in the process automatically transferred in overload, spacer pin 18 can turn in the draw-in groove 19 of below, avoids the phenomenon occurring clamping stagnation.In the present embodiment, when screening glass 12 is transferred, spacer pin 18 is positioned at the darkest draw-in groove 19, ensures the stability worn further.
Further, axle sleeve 3 can be fixed by screws on goggles support arm 5, and axle sleeve 3 is provided with mounting groove, in the cavity of rotary handle 9 between mounting groove and goggles support arm 5, rotary handle 9 is provided with blocking arm 20, and spring 4 is stuck between blocking arm 20 and mounting groove.
Further, the outside of axle sleeve 3 is also provided with catch 8, and catch 8 is provided with press section, and rotary handle 9 is provided with lower press section.When being carried out screening glass 12 by rotary handle 9 and transferring, left hand thumb and forefinger press the lower press section of rotary handle 9 and the upper press section of catch 8 respectively, overcoming spring 4 power makes spacer pin 18 lift from draw-in groove 19, then rotate counterclockwise rotary handle 9, make screening glass 12 be put into bottom from upper.
Further, the outside of catch 8 is also provided with trimmer 2 and cover plate 7, and cover plate 7, trimmer 2 and catch 8 are fixed on axle sleeve 3 by trip bolt 1.
Further, screening glass 12 is provided with transfers handle 6, transfers the upper edge that handle 6 is arranged on screening glass 12, can not block sight line.When case of emergency occurs, transfer handle 6 with left hand is directly drop-down, just achieve transferring fast of screening glass 12.
Further, the outside of screening glass 12 is also provided with over cap 13, and over cap 13 is provided with the chute 21 corresponding with transferring handle 6.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
