Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts a kind of structural representation of preferred embodiment.
Detailed description of the invention
Please refer to Fig. 1, a kind of bracket of opening and closing type, comprise bracing frame 10, turret 20 and at least one interlocking mechanism 30.
This bracing frame 10 comprises two first strut bars 11 and some levels and is fixed in the first cross bar 12 between two first strut bars 11.This turret 20 comprises the second cross bar 22 that one second strut bar 21 and some levels are fixed in the first strut bar 21.All be installed with cardan wheel 40 under this two first strut bar 11 and one second strut bar 12, and this first cross bar 12 number is equal with the second cross bar 22 number and residing height one_to_one corresponding is contour.
The lug 13 of two consistencies from top to bottom is all installed with and the lug 13 of the plurality of first cross bar 12 is vertically arranged on the plurality of first cross bar 12, this the second cross bar 22 end is between two lugs 13 of the first cross bar 12 (the first contour cross bar) of correspondence and separately establish pivot to pass two lug 13 and the second cross bar 22 ends, make the pivot of relative first cross bar of the second cross bar energy, turret energy relative support frame 10 is made to rotate to be in the folding state of parallel support frame or the open mode of vertical support frame, coordinate cardan wheel then can facilitate folding or open, then stability of strutting system is high to be in one-tenth three-legged structure when opening.
This lock-connection structure 30 is connected between one first corresponding cross bar 12 and one second cross bar 22 (the first contour cross bar and the second cross bar), this lock-connection structure comprises pivot sheet 31 and a lock 32, this pivot sheet 31 one end is articulated in the first cross bar 12 and this pivot sheet 31 pivot joint axis vertical is arranged, the deck 33 that the large neck of head is little is installed with on the end face of this pivot sheet 31 other end, this lock 33 is installed in the side of the second cross bar 22 and is provided with draw-in groove, and this lock and draw-in groove are adaptive and form and can install and remove connection structure.In one concrete structure: this deck 33 comprises a columniform cervical part of esophagus and vertically arranged and is fixed in head on cervical part of esophagus, and this head diameter is greater than cervical part of esophagus diameter; This lock 32 comprises a bow, and the central angle of this bow is greater than 180 and is less than 240 degree, affixed second cross bar in this bow one end and this bow surrounds draw-in groove, the opening of this bow two ends gap-forming draw-in groove, and this opening is towards the first cross bar; The diameter of this bow and the diameter adaptation of cervical part of esophagus, the height of this draw-in groove and the height adaptation of cervical part of esophagus, when making this interlocking mechanism 30 be in interlocking, this head is supported by deck under gravity, increases friction force, increases interlocking power.
Best, two lugs of this each the first cross bar, this two lug is fixed in the bottom surface, top of this first cross bar respectively, and this two lug is located at the middle part of the first cross bar; This first cross bar and the second cross bar equal thickness.The end of this second cross bar is set as cambered surface, or the end of this second cross bar and the first cross bar interval, make the first cross bar facilitate pivot relative.This pivot is such as screw.This first cross bar, the second cross bar are such as hollow stem.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
