The upper topside of described tarpaulin (3) is horizontally located in along batching pipe (8), its limit, lower end is fixedly arranged on the described front rail (2), the swing arm (14) that respectively is coupling of the two ends of front rail (2), this swing arm can be done the arc swing along axle, and the lower end of swing arm (13) is coupling on metope.

Above-mentioned swing arm awning wherein, also is connected a universal joint 15 between described deceleration capstan winch 11 belows and the rocking bar 12.

Above-mentioned swing arm awning, wherein, the lower end of described swing arm 14 is connected in the arm support 17 by a bearing pin 19, also is nested with a torsion spring 18 on the termination of described bearing pin 19.

Above-mentioned swing arm awning, its major metal parts are that aluminum alloy materials is made.

Have following advantage owing to take technique scheme, the utility model to compare with existing awning:

1. the utility model can be shielded in the tarpaulin after shrinking in the cover box owing to adopted Π shape cover box, makes not vulnerable to pollution of tarpaulin;

2. the utility model is owing to be provided with bolt pipe below Π shape cover box, limit, tarpaulin upper end is installed with thereon, limit, tarpaulin lower end then places on the front rail, batching pipe two ends are provided with bearing and deceleration capstan winch respectively, handle the rocking bar that is connected with the deceleration capstan winch, can be like a cork tarpaulin is convenient and closely wrap up in and be around on the batching pipe, easy to use;

3. the utility model nationality one end is coupling in be coupling a pair of swing arm on installed surface of preceding bar two ends, the other end, can be according to sunshine situation and actual needs, the arbitrarily folding and unfolding height of adjustment tarpaulin, and the length of swing arm can design according to different needs, thereby very practical;

4. the utility model is owing to be connected a universal joint between batching pipe and rocking bar, and the length of rocking bar can be according to different setting height(from bottom) designs, can make the opereating specification of tarpaulin folding and unfolding control bigger like this,, also can operate rocking bar easily even one segment distance is arranged apart from window;

5. the utility model also can be at the sheathed torsion spring of swing arm one end, and it is tightr smooth that tarpaulin is reeled.

Below the embodiment that provides by accompanying drawing and accompanying drawing the utility model is done into explanation:

Fig. 3 is the structural representation of fabric drum part in the utility model corresponding with Fig. 2;

Fig. 4 is an A-A sectional view among Fig. 3;

Fig. 5 is the structural representation of swing arm in the utility model.

As Figure 1-3, a kind of swing arm awning, comprising:

A pair of left and right sides wall bracket 1-1, the 1-2 vertical with metope, front rail 2 parallel and tarpaulin 3, the one Π shapes cover box 4 that covers along front rail 2 with metope, cover box 4 is fixedly arranged on left and right sides wall bracket 1-1, the 1-2; On a side wall support 1-1, be provided with a bracing strut 5, establish an axle bed 6 on it, the circular shaft 7 of in the circular hole of this axle bed 6, pegging graft.

Axle bed 9, one square shafts 10 that the wall bracket 1-2 of opposite side is provided with a tool square hole are placed through in the axle bed 9; One deceleration capstan winch 11 is fixedly arranged on the wall bracket 1-2; Deceleration capstan winch 11 lower ends connect a universal joint 15, hang a rocking bar 12 on it.

Referring to Fig. 4, the two ends of bolt pipe 8 are nested with respectively and are set up on circular shaft 7 and the square shaft 9, and are fixed between the both walls support simultaneously, and place the below of Π shape cover box 4, and level is established an opening circular groove 81 on batching pipe 8; The upper topside of tarpaulin 3 is fixedly arranged in the opening circular groove 81, and the opening circular groove with spline structure on its limit, lower end nationality front rail 2 is fixed on the front rail 2, and can add the tool modification shirt rim 31; Each upper shield one end cap 22 in the end of left and right sides wall bracket is so that product design is more attractive in appearance.

Simultaneously referring to Fig. 5, front rail 2 is an aluminium alloy hollow pipe, the swing arm 14 that respectively is coupling of its two ends, swing arm 14 is an aluminium alloy hollow rectangle tubulose, be pressed into the knee-

joint head

20,21 of different types respectively at its two ends, wherein the knee-joint head 20 of upper end inserts in the port of the preceding bar 1 of hollow round tubular by connecting axle 13; 21 on the knee-joint head of lower end is inserted in the arm support 17, is fixed on the installed surface body of wall by an arm support plate 16.In the circular hole of arm support 17 and knee-joint head 20, be provided with a bearing pin 19, to guarantee to do relative motion between the two, so that swing arm can be done fan-shaped swing around axle.

Also can be nested with a cylindrical torsion spring 18 between upper arm joint 20 and arm support 17, under the effect of torsion spring 18 power, swing arm 14 is subjected to a unidirectional force all the time, and it plays the effect of the tension tarpaulin that stretches tight.

During use, shake deceleration capstan winch 11, square shaft 7 rotates, and drives batching pipe 8 simultaneously and rotates, and swing arm 14 is subjected to the tarpaulin pulling and upwards swing.Because tarpaulin 3 is subjected to the common tension effect of the gravity of the torsion of torsion spring 18 and front rail 2, like this can the tarpaulin on the batching pipe 83 is smooth and closely tighten up, when tarpaulin all is contracted in the Π shape cover box 4, just be shielded in the Π shape cover box by it, form outward a rectangle box body and about two sagging swing arms.

Utilize the rotation of universal joint 15, can be at big this awning of scope of activities operation control, promptly as long as all can operate greater than any direction at 45 degree places at angle perpendicular to the ground, and the big I of opereating specification is by the length adjustment of rocking bar, the corresponding like this setting height(from bottom) that enlarges this awning.Therefore, no matter in higher market or high residential building can both use easily.(referring to Fig. 2 A)

The utility model also can be designed to automatic control, does not promptly use rocking bar, but establishes a cylindrical electrical machine in batching pipe 8, and motor is fixed on the wall bracket 2, comes the folding and unfolding tarpaulin with the rotation of Electric Machine Control batching pipe.

In addition, also available rope winder substitutes the deceleration capstan winch, can become a kind of dragline type swing arm awning.

The utility model uses aluminium alloy extrusions, and is light and handy and attractive in appearance, novel structure, and folding and unfolding is random, and is easy to use, and the scope of application is wider.
