Description of drawings
Fig. 1 is the structure chart of a kind of support blank of the utility model.
Mark among the figure: 1 is the first supporting leg, and 2 is the second supporting leg, and 3 is the 3rd supporting leg, and 4 is blank, and 5 is gripper shoe, and 51 is the first patchhole, and 52 is the second patchhole, and 53 is the 3rd patchhole, and 6 is the longitudinal midline of blank.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be the structure chart of a kind of support blank of the utility model.A kind of support blank comprises the first leg 1, the second leg 2, the 3rd leg 3, blank 4, also comprises gripper shoe 5.Described gripper shoe 5 is fixed in the back side of blank 1, this gripper shoe 5 is provided with three patchholes, is respectively be used to the first patchhole 51 of fixing the first leg 1, for the second patchhole 52 of fixing the second leg 2, for the 3rd patchhole 53 of fixing the 3rd leg 3.The axis of described the first patchhole 51 is parallel with blank 4, and longitudinal midline 6 formation one angle of the axis of the first patchhole 51 and blank 4, and the angular range of this angle is 3 °～25 °; The second patchhole 52 and the first patchhole 51 are symmetrically arranged with the longitudinal midline 6 of blank 4.Described the 3rd patchhole 53 is arranged between the first supporting leg patchhole 51 and the second supporting leg patchhole 52, and the axis of the 3rd patchhole 53 and blank 4 formation one angle, and this angular range is 20 °～50 °.
Described first leg 1 of this utility model, the second leg 2, the 3rd leg 3 are telescopic legs.Described telescopic outrigger comprises lower vertical rod, upper pright stanchion; One end of upper pright stanchion is fixedly connected with the gripper shoe of bracing frame, and the other end is inserted in the lower vertical rod, and upper pright stanchion and lower vertical rod are fixed by rotating locking apparatus.When needs are regulated the height of this whiteboard bracket, unclamp rotating locking apparatus, can be by length that upper pright stanchion is inserted in lower vertical rod being set so that the height of support blank to be set, after setting, the length that upper pright stanchion is inserted in lower vertical rod tightens rotating locking apparatus.When needs are packed up this support hickie, three supporting legs are extracted from inserting in the hole of gripper shoe get final product, therefore make things convenient for accumulating.
