Background technology

Although easel is in the market of a great variety, general easel can only support the drawing board of single size, for user has brought inconvenience.Chinese patent Granted publication number has disclosed the fixedly easel of various sizes drawing board of a kind of energy for utility model patent < < bamboo adjustable support easel > > of CN202932334U, this easel comprises bracing frame, bracing frame is provided with medium-height trestle, the upper and lower part of this medium-height trestle is connected with upper and lower adjustable plate by adjusting bolt respectively, and upper and lower adjustable plate slides up and down by the draw-in groove being arranged on medium-height trestle; Thereby with time can regulate distance between upper and lower adjustable plate to adapt to the drawing board of different size by adjusting bolt.

Yet, there is certain shortcoming in such easel: upper and lower adjustable plate can only slide up and down along medium-height trestle, this just makes this easel can only make drawing board move up and down, and can not make drawing board in same plane, carry out the adjusting of different angles, therefore, for current easel, still await further improvement.

Utility model content

Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of drawing board that can make in same plane, to carry out the easel of 360 ° of adjustings.

The technical solution of the utility model is: a kind of easel, comprise by the formed tripod of three supporting legs, joist and the first bracket and the second bracket that lay respectively at above-mentioned joist two ends, it is characterized in that: also comprise the panel on front two supporting legs that are fixed on described tripod, the middle part of described joist is hinged on this panel by an axle, and is positioned on described panel by a securing member that can make joist frame be close proximity to this panel.

As further improvement of the utility model, on described the first bracket and the second bracket, being respectively equipped with head is exposed on respective brackets medial surface for the fixing set screw of drawing board, on the medial surface of the first bracket and the second bracket, be respectively equipped with the groove of positioned opposite, in this groove, be provided with banking pin simultaneously.When drawing, the thickness of the drawing board that uses is greater than the width of groove, can drawing board be fixed by the set screw screwing on the first bracket and the second bracket; When using thinner drawing board to draw, drawing board is placed in above-mentioned groove, the banking pin in groove further carries out spacing to drawing board, make drawing board firm position, and slippage occurs when avoiding drawing board to rotate within the scope of 360 °.

Further, described the first bracket becomes the bracket of same structure with the second bracket design, on this bracket, have the locating slot that oral area is less than bottom, the inserting slidably of described joist is in this locating slot, on this bracket, be threaded and be exposed to the adjusting bolt of this locating slot bottom with head simultaneously, by this adjusting bolt can bracket and joist between elasticity, adopt oral area to be less than the locating slot of bottom, when being connected between bracket and joist is comparatively loosening, can avoid joist slippage to go out the locating slot on bracket; In locating slot, be also provided with the supplementary plate between described joist and adjusting bolt, this supplementary plate can increase the lifting surface area between adjusting bolt and joist on the one hand, so that location is more firm between joist and bracket, also can avoid on the other hand for a long time joist being compressed joist being caused to wearing and tearing because of adjusting bolt.

As preferably, described joist inner side is provided with the cushion between described joist and described panel, and this cushion can prevent easel phase mutual friction and cause damage between joist and panel in long-term use.

In above-mentioned each scheme, described axle is a bolt, and described securing member is the nut being threaded on this bolt.Certainly, securing member herein also can adopt the handle of prior art medial end portions band eccentric cam, and the cam of this handle is arranged on one end of axle rotationally, by pulling handle, joist can be close to panel.

Preferably, the bottom of described front two supporting legs is provided with a stabiliser bar, this stabiliser bar the stability that can increase easel is set; The bottom of described three supporting legs is fixed with slipmat, can prevent that easel from sliding with respect to ground.

Compared with prior art, because the utility model is provided with panel on front two supporting legs, and utilize a securing member that joist is hinged on this panel by an axle, regulate this securing member joist to be rotated to more loose after holding state with respect to panel, turn to while needing position securing member is tightened, thereby can realize, drawing board is regulated within the scope of 360 °.
