The specific embodiment

For structure and the characteristics place that specifies the utility model, lift explanation of following preferred embodiment and conjunction with figs. as back now:

See also Fig. 1 and shown in Figure 2, the cantilevered external support frame that the utility model provided consists predominantly of: one first cantilever 11, one second cantilever 12, one first gag lever post 13, one first swing component 14 and one first keeper 15.

This first cantilever 11 is articulated in a machine 80 1 sides in this preferred embodiment.

This second cantilever 12 is articulated by one first pivot 16 and this first cantilever 11, so this second cantilever 12 this first cantilever, 11 pivots relatively.

This first gag lever post 13 is on affixed this first pivot 16.In this preferred embodiment, this first pivot 16 radially has a fixing hole 161, and this fixing hole 161 is through these first pivot, 16 axle center, and this first gag lever post 13 is inserted in this fixing hole 161.In addition, a fixture 17 (not shown) are arranged, penetrate this first pivot 16 and pass this fixing hole 161 and this first gag lever post 13 from these first pivot, 16 axle center.

This first swing component 14; Have one first slide 141, one first swing arm 142 and one second swing arm 143; This first slide 141 slides along this first gag lever post 13; These first swing arm, 142 two ends articulate this first slide 141 and this first cantilever 11 respectively, and these second swing arm, 143 two ends articulate this first slide 141 and this second cantilever 12 respectively.In this preferred embodiment, what must specify is, this first slide 141 also has a perforation 144, and this first slide 141 makes this first slide 141 slide along this first gag lever post 13 with the mode that this first gag lever post 13 passes this perforation 144.

This first keeper 15 is arranged at this first slide 141, limits this first slide 141 and relatively moves with this first gag lever post 13.In this preferred embodiment, this first keeper 15 is a bolt, and spiral shell is located at this first slide 141 and is stretched into this perforation 144, and then presses this first gag lever post 13, reaches and limits the function that this first slide 141 and this first gag lever post 13 relatively move.

The occupation mode of the cantilevered outside support of next, introducing the utility model and being provided.

As shown in Figure 3; The cantilevered external support frame that user's desire provides the utility model is adjusted into maximum situation; This first cantilever 11 is turned to outside this machine 80 with this second cantilever 12 each other, and this moment, this first slide 141 can slide onto an expanded position along this first gag lever post 13.At this moment, if will keep the relative position of this first cantilever 11 and this second cantilever 12, the user uses this first keeper 15 to limit the relative displacement between this first slide 141 and this first gag lever post 13, can keep this preferred embodiment and be maximum situation.

Afterwards; As shown in Figure 4, if the cantilevered external support frame of wanting folding the utility model to be provided then unclamps this first keeper 15; Make this first slide 141 to relatively move along this first gag lever post 13; It is other in this machine 80 with these second cantilever, 12 closures to rotate this first cantilever 11 subsequently, and this first slide 141 can slide onto a collapsed position along this first gag lever post 13, reaches the purpose of this preferred embodiment of folding.

Come again; Extremely shown in Figure 6 like Fig. 5; Introduce the utility model second preferred embodiment, itself and this first preferred embodiment is roughly the same, difference be in: more have more one the 3rd cantilever 21, one the 4th cantilever 22, one second gag lever post 23, one second swing component 24 and an adjustment sleeve 31.

The 3rd cantilever 21, in this preferred embodiment with preceding embodiment in this first cantilever 11 likewise be articulated in this machine 80.

The 4th cantilever 22 is articulated by one second pivot 25 and the 3rd cantilever 21, so the 4th cantilever 22 the 3rd cantilever 21 pivots relatively.

This second gag lever post 23 is on affixed this second pivot 25.

This second swing component 24; Have one second slide 241, one the 3rd swing arm 242 and one the 4th swing arm 243; This second slide 241 is to slide along this second gag lever post 23; The 3rd swing arm 242 two ends articulate this second slide 241 respectively and articulate this second slide 241 and the 4th cantilever 22 respectively with the 3rd cantilever 21, the four swing arms 243 two ends.This second slide 241 also has a perforation 244, and this second slide 241 is the mode of passing this perforation 244 with this second gag lever post 23, makes this second slide 241 move along this second gag lever post 23.

This adjusts sleeve 31; Two ends sheathed respectively this first gag lever post 13 and this second gag lever post 23; These adjustment sleeve 31 two ends have one second keeper 32 respectively, and respectively this second keeper 32 limits respectively between this adjustment sleeve 31 and this first gag lever post 13 and this second gag lever post 23 and relatively moves.

What deserves to be mentioned is that this preferred embodiment also has one the 3rd keeper 33, is to be arranged at this second slide 241, limits this second slide 241 and relatively moves with this second gag lever post 23.In addition, in this preferred embodiment, the 3rd keeper 33 is a bolt, is that spiral shell is located at this second slide 241 and is stretched into this perforation 244, and then presses this second gag lever post 23, reaches and limits the function that this second slide 241 and this second gag lever post 23 relatively move.

Then introduce the occupation mode of the utility model second preferred embodiment.

See also Fig. 7 to shown in Figure 8; When the cantilevered external support frame that user's desire is provided this second preferred embodiment is adjusted into maximum situation; Be with this first cantilever 11 and this second cantilever 12, and the 3rd cantilever 21 turn to outside this machine 80 with the 4th cantilever 22.At this moment; The user uses this first keeper 15 to limit the relative displacement between this first slide 141 and this first gag lever post 13; And use the 3rd keeper 33 to limit the relative displacement between this second slide 241 and this second gag lever post 23, can keep this preferred embodiment and be maximum situation.What must specify is; If will keep this first cantilever 11 and this second cantilever 12; And the distance between the 3rd cantilever 21 and the 4th cantilever 22 is used respectively this second keeper 32 to limit respectively to relatively move between this adjustment sleeve 31 and this first gag lever post 13 and this second gag lever post 23 and is got final product.

See also shown in Figure 9; If the cantilevered external support frame of wanting second preferred embodiment of folding the utility model to be provided; Then unclamp this first keeper 15 and the 3rd keeper 33 (not shown); Make this first slide 141 to relatively move along this first gag lever post 13, this second slide 241 can relatively move along this second gag lever post 23, rotates this first cantilever 11 and these second cantilever, 12 closures subsequently; And the 3rd cantilever 21 and the 4th cantilever 22 closures, reach the purpose of folding the utility model.

What need special instruction is; See also shown in Figure 10; In fact the user only need use this first keeper 15 and the 3rd keeper 33 respectively, can fix the angle between this first cantilever 11 and this second cantilever 12, and the angle between the 3rd cantilever 21 and the 4th cantilever 22; And aforementioned both angles can be different, show like figure.

Can know by above-mentioned first preferred embodiment and second preferred embodiment; The cantilevered external support frame that the utility model provided can positively be adjusted the size of bracing frame to sheet material, and can reduce the occupied area of cantilevered external support frame by folding.
