Reset locking is carried out, while the movement of pressure ram 10 is also locked, the storage of fixed plate 3 is completed and is locked, will during second
Slide bar 12 is pulled to side, is unlocked to closing piece 8, and an elastic potential energy saved bit by bit in the process constantly discharges on the first spring 11,
The elastic force of application rearwardly pushes pressure ram 10, and closing piece 8 and telescoping tube 9 coordinate pressure ram 10 to be carried out at the same time rotation, most
Enable eventually and 3 Automatic-expanding of fixed plate and reaches certain angle, it, can be by the first spring 11 when by External force interference
External force is absorbed and is kept fixed the angle of plate 3 and is not easy to shake by row buffering.
Operation principle：The outdoor billboard that can be stretched when in use, passes through the setting of control piece 5 so that billboard
Good fixed effect can be reached under display state and receiving state, in specifically used, by fixed case 6 to control piece 5
Connection is established between fixed frame 1, is played a supporting role, under being used cooperatively of fixed link 7, closing piece 8 and telescoping tube 9, closing piece 8
It is rotated for the center of circle with fixed link 7 with telescoping tube 9, when closing piece 8 turns to horizontal position, meeting and the fixture block 13 on slide bar 12
It contacting and squeezes so that 14 deformation retract of resetting spring, resetting spring 14 constantly save bit by bit elastic potential energy during deformation,
The direction of motion of slide bar 12 towards two slide bar 12 of left or right side or so is slided on the contrary, as sliding distance increases, closing piece 8
One end can inswept fixture block 13 side and rise to the upper surface of fixture block 13, squeezing effect solution of the closing piece 8 to fixture block 13 at this time
It removes, resetting spring 14 discharges the elastic potential energy saved bit by bit before, is applied to the elastic band moving slide-bar 12 on fixture block 13 in
Between move, due to the blocking of slide bar 12 so that closing piece 8 can not be rotated backward to original state, to closing piece 8 carried out reset locking,
In fixed plate 3 when being rotated, pressure ram 10 can be moved forward or backward, pass through telescopic rod 16, fixation in telescoping tube 9
Cylinder 15 and second spring 17 are used cooperatively, and can ensure to keep rotation to connect with pressure ram 10 while pressure ram 10 moves
It connects, when the movement of the first spring 11 being divided into two processes, and being set under 11 0 potential energy states of the first spring, fixed plate 3 reaches
Maximum folding angle, one of them in the process presses fixed plate 3 so that fixed plate 3, which rotates, simultaneously finally stores to solid
Determine in frame 1, in rotation process, pressure ram 10 is moved to front, is constantly squeezed the first spring 11 so that the first bullet
Gradually accumulation elastic potential energy can carry out reset locking by slide bar 12, squeeze simultaneously spring 11 when extruding reaches horizontal position to locking bar 8
The movement of compression bar 10 is also locked, and the storage of fixed plate 3 is completed and is locked, and pulls slide bar 12 to side during second, right
Closing piece 8 is unlocked, and the elastic potential energy saved bit by bit during one on the first spring 11 constantly discharges, and the elastic force of application is by pressure ram 10
It is rearwardly pushed, closing piece 8 and telescoping tube 9 coordinate pressure ram 10 to be carried out at the same time rotation, finally enable fixed plate 3 automatic
Be unfolded and reach certain angle, when by External force interference, by the first spring 11 can into row buffering by external force absorb and
It is kept fixed the angle of plate 3 and is not easy to shake.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
