Open wide.
Detailed description of the invention
As shown in Fig. 1 to Fig. 6, a kind of sunshade, be arranged on tetragonal courtyard wall use, mainly by polylith sunshading board 1,
Many strut 4, cross bar 5 of 2, two parallel guide rail 3, two root posts, multiple coaster 6 and that axle connects from beginning to end are dynamic
Power apparatus 7 forms.Power set and a controller are connected, and controller controls the switch of power set.
Described sunshading board uses frame structure, every piece of sunshading board be formed around framework, keep the hard of sunshading board by confining
Deflection, prevent because longer unsettled time buckling phenomenon occurs.If the span of sunshading board is the biggest, it is also possible to install additional in framework and add
Strong muscle.
Two described closed slides are separately fixed on the relative wall in two, courtyard, by being located at screening between adjacent sunshading board
Hinge on sun plate framework so that it is can fold.
Being provided with a strut axis hole 21 at the center of each strut 2, the middle side edge at every piece of sunshading board is provided with a sunshading board
Axis hole, every strut is with corresponding sunshading board by strut axis hole with sunshading board axis hole axle even;Described strut is in sunshading board both sides
Symmetry arrangement.
When sunshading board opens, sunshading board forms the angle of an acute angle with adjacent strut, and the upper end of strut is higher than sunshading board.
The length of strut is more than the side edge length of the sunshading board connected with its axle, when sunshading board opens the state of the level of being in completely, strut
Still have certain angle with horizontal plane, when needs launch or draw sunshading board in, this angle plays the effect of guiding.
Guide rail 3 is provided with coaster 6, and coaster is placed on guide rail by the pulley 61 mated with guide rail 3, two adjacent supports
The bottom of bar is linked on a coaster 6 by a fixing axle axle.
Two described root posts 4 are vertical with guide rail, and the bottom of each column is placed on the first coaster 62 on a guide rail,
The two ends of cross bar 5 are separately fixed at the top of two root posts.I.e. two root posts are respectively disposed on two guide rails parallel to each other
On first coaster, cross bar is placed in the top of two root posts, forms four square frames of a lower opening.When column is slided on guide rail
During row, cross bar can be driven also to be displaced outwardly.
Described power set 7 mainly include motor and planetary transmission, the output shaft of described planetary transmission
It is connected with power gear.The right side of described power gear arranges a right driven pulley 8 engaged, left side arrange one with
The left driven pulley 9 of its engagement.
Right line shaft 81 and left line shaft 91 are fixed on cross bar 5 by top chock;One end of right line shaft 81 with right from
Driving wheel 8 is connected, and the other end is connected with right driving wheel 82, and right driving wheel 82 engages with right drive 83, right drive 83
In the top of right screw rod 84, right screw rod 84 is fixed on inside column by right bearing seat 85, is provided with and moves right on right screw rod
Block 86, the outer wall of right screw rod 84 is provided with screw thread, described move to right motion block 86 in be provided with the female thread mated with right screw rod;Make
Move to right motion block to move up and down when right screw rod rotates.
Accordingly, one end of left line shaft is connected with left driven pulley, and the other end is connected with left driving wheel, left driving wheel and left biography
Driving wheel engages, and Left Drive wheel is positioned at the top of left screw rod, and left screw rod is fixed on inside column by left shaft holder, on left screw rod
Being provided with and move to left motion block, the outer wall of left screw rod is provided with screw thread, described move to left motion block in be provided with the female thread mated with left screw rod;Make
Move to left motion block to move up and down when left screw rod rotates.
Described left screw rod is full symmetric with right screw rod and screw thread is identical;Move to left motion block and be provided with two symmetrical lugs, right
Movable block is provided with two symmetrical lugs;Catch bar 22 it is provided with between the wall vertical with guide rail and column, catch bar
One end is fixed on the wall vertical with guide rail by fixing seat 23, and the other end moves to left motion block or the right side by being positioned at inside column
Lug on movable block is hinged on and moves to left motion block or move to right on motion block, and the upper articulation of the initiating terminal of strut 2 is moving to left motion block or the right side
On another lug on movable block, other adjacent strut end is hinged by axis hole and axle;It is fixed on the promotion on fixing seat
The position of one end of bar is less than the position of the other end of promote-side.
During as it is shown in fig. 7, need to open sunshade, to power set power transmission, power set drive power gear to rotate forward,
Power gear drives right driven pulley 8 and left driven pulley 9 to reversely rotate, and right driven pulley drives right line shaft 81 and right driving wheel 82
Reversely rotating, right driving wheel drives right drive 83 and right screw rod 84 to rotate forward, and the screw rod of rotation promotes and moves to right motion block 86
Move down;Meanwhile, power gear drives left driven pulley 9 to reversely rotate, and left driven pulley drives left line shaft 91 and left driving
Taking turns and reversely rotate, left driving wheel drives Left Drive wheel and left screw rod to rotate forward, and the screw rod promotion of rotation moves to left motion block and moves down.
Move to right motion block and move to left motion block and synchronize to move down, and promoting the catch bar 22 being attached thereto past for axle center with fixing seat 23 respectively
Under move in a circle, catch bar is during motion, and column produces horizontal thrust, under the effect of this thrust, column
Coaster below 4 is displaced outwardly along guide rail.Strut 2 is outwards stretched out simultaneously, and strut band fly block and sunshading board synchronize to stretch along guide rail
Opening, putting in place until stretching, motor quits work.
As shown in Figure 8, during gathering, motor reversely rotates, and makes left screw rod and right screw rod reversely rotate, thus drives catch bar
Drawing in strut, strut drives sunshading board to draw in again, puts in place until drawing in, and motor quits work.
Motor is used to drive sunshade open or draw in, it is to avoid the equilibrium problem of sunshade two lateral movement.Make sunshade
Both sides stress equalization when canopy opens or draws in, speed is consistent.
Described catch bar is in the same plane with strut, and its projection is overlapping with the projection of guide rail.
In addition to the coaster near catch bar, remaining coaster top is provided with the lug with guide rail parallel;With pulley axle strut even
Connect with the lug axle at coaster top.
Described sunshading board uses glass or acrylic.
The top of right screw rod is connected through the diapire of cross bar with right drive;The top of left screw rod passes the diapire of cross bar and left biography
Driving wheel is connected.
Load onto sunshade at rectangle courtyard, under the driving of power set, by left screw rod and the synchronous rotary of right screw rod, make a left side
Movable block and move to right motion block and synchronize to move downward or upward, thus promotes push rod and strut, make the strut being located at sunshading board both sides with
Step is opened or draws in, thus drives sunshade to open or draw in.
When running into sleety weather or needing sunshade, user has only to the on & off switch pressing on controller, it becomes possible to make sunshade
Open, so that courtyard is covered by sunshade, wait rain to cross day feelings, or after the sun sets, on & off switch can be pressed again, make sunshade
Canopy draws in.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, the art
Those of ordinary skill, in the essential scope of the present invention, make a variety of changes or substitute, also should belong to the protection model of the present invention
Farmland.
