Description
Technical field
The utility model relates to a kind of easel, specifically refers to a kind of easy-to-dismount easel.
Background technology
In order to satisfy the needs of drawing or field sketching, the painter often is furnished with easel.And present easel has presented multiple structure, is common with portable easel again wherein, and it generally comprises rear support leg, left branch leg and the right supporting leg that can form tripod.Simultaneously for the painter that can be applicable to all ages and classes section or the drawing needs of different gestures, the height and the angle of general easel all can be regulated, as the Chinese patent Granted publication number be the bascule between disclosed left and right supporting leg in " a kind of portable easel " of CN2488716Y, rear support leg and support body, and as the Chinese patent Granted publication number be support bar disclosed in " the multi-functional easel " of CN2616408Y and the bascule between the supporting leg.Promptly two relative to can move or rotatable parts between regulate relative position and relative positioning by a securing member, on wherein parts of above-mentioned two parts, generally have through hole, this through hole can be slotted hole or circular hole, have through hole on another parts, this through hole also can adopt slotted hole or borehole structure, and securing member adopts screw bolt and nut, and bolt after passing through hole and through hole links into an integrated entity two parts.When need regulating height or angle, unscrew nut, make two parts relatively move (or rotation) to desired height (or angle), screw nut again, make two parts keep relative fixed, reach the purpose of regulating height or angle with this.
In each easel in sum owing to all adopted bolt, nut structure in their active connection place, therefore in actual use, need repeatedly rotate nut after, just can reach fastening or loosening corresponding parts.Obviously, such structure dismounting is got up and is comparatively wasted time and energy, and operating efficiency is low.This just seems extremely inconvenient for the easel of frequent adjusting angle of needs or height.
The utility model content
Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of operation comparatively easily, easel easy to assemble easily.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this easel easy to assemble comprises first parts and second parts that are connected by securing member, wherein have through hole on first parts, have through hole on second parts, it is characterized in that: described securing member includes a connecting rod and head is the handle of cam, one end of this connecting rod is provided with block, the other end of this connecting rod is connected with a bearing pin after passing above-mentioned through hole and through hole, and the cam on the described handle then is installed on this bearing pin.
In such scheme, described first parts can be for being used for supporting the main framing of drawing board, and the middle part of this main framing has long slot bore, on the long slot bore two side, have with long slot bore in the same way strip hole and form described through hole; The tripod of described second parts for shelving for above-mentioned main framing, this tripod comprises that again the upper end is resisted against the left and right supporting leg of main framing both sides and upper end and is embedded into rear support leg in the described long slot bore, and described through hole is out the circular hole in above-mentioned left and right supporting leg and rear support leg upper end.
Perhaps, described first parts are still for being used for supporting the main framing of drawing board, but the pedestal that is used for supporting this main framing adopts other structure, this moment is above-mentioned to fasten part and can be used in main framing and be used between the upper limit position block of spacing drawing board, and at this moment described through hole is out the long slot bore in the middle part of main framing; And second parts are the upper limit position block that is attached to the main framing upper surface, and described through hole is out the circular hole on this upper limit position block.
For the lower limit of drawing board, the lower limit lagging can be set on main framing; Perhaps in the tripod of forming by left and right supporting leg and rear support leg, realize spacing by lower position block is set on the left and right supporting leg, at this moment, can adopt above-mentioned securing member between left and right supporting leg and the limited block separately, be to have vertical hole on the left and right supporting leg, described first parts are left branch leg or right supporting leg, and described through hole is described vertical hole; And second parts are lower position block, and described through hole is out the circular hole on lower position block.
When the tripod of being made up of left and right supporting leg and rear support leg has Telescopic, left and right supporting leg and rear support leg adopt upper supporting leg and following leg structure respectively, also can by above-mentioned securing member connect between the upper and lower supporting leg this moment, be that described first parts are upper supporting leg, described through hole is out on upper supporting leg and can holds vertical hole of supporting leg down; And second parts are that following supporting leg, described through hole are out the circular hole in following supporting leg upper end.
In above-mentioned each scheme, in order to make the tighter of two parts clampings, wherein be shaped on external screw thread in an end at connecting rod, and described bearing pin or block are threaded mutually with this external screw thread end, rotary pin shaft or block just can be adjusted the distance between block and the bearing pin, like this when securing member clamp to use, just can not be subjected to the influence of two component processing errors, can realize clamping function easily.
In order to protect the parts surface of touching mutually with cam edge, on the connecting rod of bearing pin inboard, also be with elastic washer and pad successively, avoided cam to contact so on the one hand with the direct of parts, utilize elastic washer can make the tighter of each parts clamping on the other hand.
Compared with prior art, because the utility model adopts cam handle to replace nut, thereby when the mounting or dismounting easel, need not repeatedly to rotate, need only pulling handle lightly, utilize the eccentric structure of handle overhead cam, can spur connecting rod, make between first parts on the easel and second parts to clamp relatively or relative separation, and then can realize the relative positioning of two parts or movable relatively.Obviously, the utility model operates both light, and is quick again, thereby regulates the easel height or angle brings great convenience to the painter.
