Description

A kind of easel

Technical field

The utility model relates to a kind of easel, relates in particular to a kind of adjustable for height easel.

Background technology

Easel is the necessary tool that art worker and student draw work of fine arts.Consider actual conditions, the breadth size of each paint is had nothing in common with each other, the adjustable for height easel of some drawing board bracing frames is invented, as the patent No. is the Chinese utility model patent " easel can stretch " of ZL200920115052.8 (notification number is CN201362130Y), discloses a kind of easel applicable to certain drawing board breadth scope.This easel that can stretch, comprise base and palette rack, be provided with linkage between base and the palette rack, palette rack comprises left plate, right plate, cross tube and sheer pole, the lifting backup plate is installed in the front portion of palette rack, the lifting backup plate comprises lower baffle plate and middle backup plate, the lower end of middle backup plate is installed in the middle part of lower baffle plate, the two ends of lower baffle plate are provided with latch, latch can slide up and down to be installed in the left plate of palette rack, on the right plate, the front portion of lower baffle plate installs and fixes clip slot, and fixedly the two ends of clip slot are positioned at the front portion of palette rack, have vertical guide groove on the lifting backup plate, the cross tube that first bearing pin passes palette rack is nested in the vertical guide groove; The lifting backup plate has vertical slide rail, in the vertical slide rail stretching bar is installed, and the middle part of stretching bar has vertical approaching channel, and the upper connecting rod that second bearing pin passes the lifting backup plate is nested in the vertical approaching channel.

In this can stretch easel, only substructure height is adjustable relatively for the lifting backup plate, so, and when practical application, drawing board altitude range applicatory is smaller, the height that drawing board is shelved also is restricted, and can not rise too high, and this is for the bigger paint of breadth, when the drawing of the lower part of drawing board, the painter need reduce the height of oneself, and is just relatively more painstaking, uses comfortable inadequately.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of easel at the present situation of prior art, and its drawing board adjustable height scope is bigger, and drawing board breadth scope applicatory is bigger, and makes that actual use is more comfortable.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this easel, comprise base, be arranged on the pedestal on the base and be arranged on and be the inverted T shape lifter plate on the pedestal front, wherein, the lateral part of lifter plate is positioned at the office, bottom of pedestal, the vertical part end of lifter plate stretches out above pedestal, this lifter plate pedestal is relatively located slip up and down, it is characterized in that: also be provided with the drawing board fixed mount that the relative lifter plate of an energy is located slip up and down in the front of described lifter plate, this drawing board fixed mount is elongated substantially and have the strip hole of vertical setting, and the vertical part of described lifter plate just is arranged in this strip hole.

Wherein, described lifter plate is relatively located the drawing board fixed mount of slip up and down, can adopt existing various technology and realize, for making structure simpler, easy row swift to operate, can adopt following scheme: the vertical part both sides of described lifter plate respectively are provided with a chute, the dual-side of the strip hole of described drawing board fixed mount is along respectively having an inwardly central chimb that protrudes, each chimb snaps onto on the lifter plate in the corresponding chute, thereby make the drawing board fixed mount relatively lifter plate do vertical relatively moving, and, the vertical part front of lifter plate has a breach, be provided with a size and the movable block that breach adapts in the breach, be provided with one first set bolt at the vertical part back side of lifter plate, the afterbody of this first set bolt passes the vertical part of lifter plate and is inserted within the movable block; When needing location drawing board fixed mount, tighten first set bolt, the afterbody of first set bolt just promotes movable block to frontal, and the both sides of movable block will be tight against forward in the inboard of the strip hole of drawing board fixed mount, thereby makes the relative lifter plate of drawing board fixed mount location motionless.

Described pedestal is relatively located the lifter plate of slip up and down, can adopt existing various technology and realize, for the location that makes the relative pedestal of lifter plate more reliable, can adopt following scheme: the both sides of described pedestal are respectively arranged with a slide rail, the both sides, lateral part of described lifter plate extend to form projection laterally, each projection is embedded in the pedestal in the corresponding slide rail and can slides up and down along slide rail, the central authorities of described pedestal are embedded with the tooth bar that a front has many latches, the bottom center of described crane lateral part is provided with a jump ring, this jump ring comprise forward part with can be relative to rear section that forward part is rotated, wherein, the bottom of forward part and crane lateral part fixes, the end of rear section snaps onto in the latch, and, be provided with torsion spring between forward part and the rear section, this torsion spring one end and forward part offset, the other end and rear section offset, and the end that makes the rear section has the trend of upwards rotating all the time, so, when the relative pedestal of crane upwards slides, the rear section of torsion spring can be along tooth bar and relatively forward part rotate, when crane slides into the position that needs, the end of torsion spring rear section can't arbitrarily rotate because of snapping onto in the latch, at this moment, crane is just motionless with the pedestal location reliably.

For making this easel can be applicable to the drawing board of different sizes better, can be provided with two decks up and down on the described drawing board fixed mount, each deck by being arranged on the deck front second set bolt and the lock dog that is arranged on the deck back side and relatively the drawing board fixed mount fix, the bottom of upper blocking seat has first draw-in groove, the top of following deck and bottom have second draw-in groove, the 3rd draw-in groove respectively, so, the painter can be as required and use upper blocking seat or down deck come the upper edge of drawing board blocked and establish, very practical.

Compared with prior art, advantage of the present utility model is: locate the setting up of drawing board fixed mount of slip up and down by lifter plate relatively, making not only has lifter plate can regulate height up and down in the easel, and the drawing board fixed mount also can be regulated height up and down, enlarged the adjustable range of drawing board height, also promptly, enlarged the drawing board scope of application, drawing board breadth scope applicatory is bigger, and, but the lower part of drawing board can rise in painter's the opereating specification, and is more comfortable, is more suitable for actual use.
