Abstract

The utility model discloses an overturning mark comprising a mark body. The mark body comprises a quadrilateral frame structure and is provided with more than three same right triangular prisms whose axes are positioned on the same plane; the triangular prisms are horizontally or vertically and equidistantly mounted in a quadrilateral frame; the quadrilateral frame provides rotating support for supporting shafts or shaft holes which are arranged on the axis centers of two ends of the triangular prisms; the triangular prisms are respectively articulated with the same deflecting plate on the equidirectional end face and pushed and pulled by the deflecting plate to synchronously rotate around the triangular prisms; the angle and the distance of each articulated point relative to the centers of the triangular prisms are equal so as to ensure the synchronous rotation of various triangular prisms; and the deflecting plate is pushed or pulled by one drive mechanism, so that equidirectional prism surfaces of various triangular prisms respectively combine different mark contents when rotating to the same plane. Through the synchronous rotation of the plurality of triangular prisms, the utility model converts and displays different mark contents and can convert the mark contents on the mark according to the requirement.

In the such scheme, described driving mechanism can be a straight-line feed mechanism, described straight-line feed mechanism is preferably motor-driven lead screw transmission mechanism, described lead screw transmission mechanism comprises screw mandrel and cover transmission nut thereon, described screw mandrel two ends are supported by being fixed on the quadrilateral frame top chock, described motor shaft is connected with screw mandrel to drive its rotation, described transmission nut and swinging plate form a sine mechanism by the slide block slide way mechanism and drive swinging plate, preferably on described transmission nut, stretch out the pull bar of a band bar-shaped trough, described bar-shaped trough is enclosed within and forms the slide block slide way mechanism on the driving lever that swinging plate is provided with, thereby drive the triangular prism rotation when screw mandrel is made linear running, to drive swinging plate at screw mandrel rotating drive transmission nut, based on same principle, also can adopt and on transmission nut, stretch out a driving lever, be inserted in the bar-shaped trough that swinging plate is provided with, drive triangular prism and rotate thereby equally also can when screw mandrel is made linear running, promote swinging plate at screw mandrel rotating drive transmission nut.

Straight-line feed mechanism can also be motor-driven pinion and rack, described motor is connected with gear to drive its rotation, described gear rotates the tooth bar translation that makes with its engagement, described tooth bar and swinging plate form a sine mechanism by the slide block slide way mechanism and drive swinging plate, preferably on described tooth bar, stretch out the pull bar of a band bar-shaped trough, described bar-shaped trough is enclosed within and forms the slide block slide way mechanism on the driving lever that swinging plate is provided with, thereby promote swinging plate when driving the driving rack translation and drive the triangular prism rotation to rotate at gear, based on same principle, also can adopt and on tooth bar, stretch out a driving lever, be inserted in the bar-shaped trough that swinging plate is provided with, equally also can when gear rotates the translation of drive driving rack, promote swinging plate, rotate thereby drive triangular prism.

Described driving mechanism can also adopt rope to spur, specifically comprise motor, rope, pulley, described rope is walked around motor, rope forms closed circulation and rotates, described rope a bit is fixed on the swinging plate, with pulling swinging plate when motor rotating band running rope rope comes back rotation, rotate thereby drive triangular prism.

Can also be that described triangular prism level equidistantly is installed in the quadrilateral frame, swinging plate also correspondingly vertically is provided with thus, described swinging plate is provided with the counterweight that is enough to overcome the triangular prism rotary resistance, described driving mechanism comprises motor, rope, described rope a bit is fixed on the swinging plate, described rope is walked around motor shaft elevator when it rotates and is drawn high swinging plate, thereby and when loosening swinging plate under action of gravity, drop and realize that swinging plate moves up and down, rotate thereby drive triangular prism.

In the above scheme, also be provided with bearing between preferred described triangular prism back shaft and the quadrilateral frame, can make the more suitable cunning of upset.

The beneficial effects of the utility model are: the utility model rotates synchronously by a plurality of triangular prisms, thereby conversion demonstrates different sign contents, realize the sign content conversion as required on the sign, satisfy traffic administration better with the progressive demand that constantly changes of epoch.

Embodiment

As Fig. 1, shown in Figure 2, the upset sign, comprise sign body 1, sign body 1 comprises a quadrilateral frame shelf structure, sign body 1 is provided with a plurality of (being 7 in this embodiment) identical and axis at conplane regular triangular prism 2, triangular prism 2 vertically and equidistantly is installed in the quadrilateral frame, provide rotational support by quadrilateral frame to the back shaft 21 that center, triangular prism two ends is provided with, because of adopting vertical installation, rotate smoothly for making, transverse bearing 22 also is installed between back shaft 21 and the quadrilateral frame, each triangular prism 2 one in the same way end face be articulated in same swinging plate 3 respectively and rotate synchronously around triangular prism 2 axle center by its push-and-pull, each pin joint 23 is identical with respect to the angle and the distance at triangular prism center, to guarantee each triangular prism rotational synchronization, swinging plate 3 is promoted by a driving mechanism 4, so that the equidirectional cylinder of each triangular prism 2 is combined into the unlike signal content when turning to same plane respectively.

As Fig. 3, shown in Figure 4, driving mechanism 4 is the lead screw transmission mechanism that motor 41 drives, lead screw transmission mechanism comprises screw mandrel 42 and cover transmission nut 43 thereon, screw mandrel 42 two ends are supported by the bearing seat that is fixed on the quadrilateral frame, 41 in motor is connected to drive its rotation with screw mandrel 42, transmission nut 43 and the pull bar 432 that stretches out a band bar-shaped trough 431, bar-shaped trough 431 is enclosed within and forms the slide block slide way mechanism on the driving lever 31 that swinging plate 3 is provided with, transmission nut 43 forms a sine mechanism with swinging plate 3 by the slide block slide way mechanism like this, drive swinging plate 3 and when screw mandrel 42 is made linear running, drive swinging plate 3, rotate thereby drive triangular prism 2 at screw mandrel 42 rotating drive transmission nuts 43.
