Description
技术领域technical field
本实用新型涉及一种油画布绷架。The utility model relates to an oil painting canvas stretcher.
背景技术Background technique
绷油画布是油画绘画前重要的工作之一,主要目的是使褶皱的油画布通过绷紧而变得平整,这样有利于作画,并能保证油画的质量。目前绷油画布主要通过绷架实现,绷架实际上是四边形的框架,有以下几个步:Stretching oil canvas is one of the most important tasks before oil painting. The main purpose is to make the wrinkled oil canvas smooth by stretching, which is conducive to painting and can ensure the quality of oil painting. At present, the stretching of oil canvas is mainly realized by the stretching frame, which is actually a quadrilateral frame, and there are the following steps:
1、将油画布的经纬线与内框四边摆正,否则歪斜的布纹将影响画面的肌理美感(油画布的大小一般应比内框大4~5cm),然后胥画布剪裁下来。1. Align the longitude and latitude of the oil canvas with the four sides of the inner frame, otherwise the skewed cloth pattern will affect the texture and beauty of the picture (the size of the oil canvas should generally be 4-5cm larger than the inner frame), and then cut the canvas.
2、用几个钉子或图钉将画布先临时固定在内框四角处,使其保持与内框的平行,目的也是为了保持在绷布时不产生歪斜。2. Use a few nails or thumbtacks to temporarily fix the canvas at the four corners of the inner frame to keep it parallel to the inner frame. The purpose is also to keep it from being skewed when stretching.
3、用木炭在画布上沿内框四边的外角画上直线,这样可以在后面绷拉时帮助掌握分寸,也可以保持用力的一致。3. Use charcoal to draw straight lines on the canvas along the outer corners of the four sides of the inner frame, so as to help you grasp the measure when stretching later, and also keep the force consistent.
4、钉画布钉子时应从内框长边的外侧中心处开始,再在对应的另一边钉第二个,接着以同样的方法钉两个短边。这时画布中央会形成一个菱形皱折,然后按四边的顺序交叉方向进行。4. When nailing canvas nails, start from the outer center of the long side of the inner frame, then nail the second nail on the other side, and then nail the two short sides in the same way. At this time, a diamond-shaped wrinkle will be formed in the center of the canvas, and then cross directions in the order of the four sides.
传统的绷架在使用的时候,需要用钉子顶住画布,然后依靠人力拉画布实现绷紧画布,这样人的用力难免不均匀,而且一旦用力过度还从钉画布的部位开始撕坏画布,造成画布不必要的损失。When the traditional stretcher is in use, it is necessary to use nails to support the canvas, and then rely on manpower to pull the canvas to tighten the canvas, so that the human force is inevitably uneven, and once the force is excessive, the canvas will be torn from the nailed part of the canvas, resulting in Unnecessary loss of canvas.
实用新型内容Utility model content
为解决上述问题,本实用新型的目的是提供一种油画布绷架,可以使油画布绷的更平整。In order to solve the above problems, the purpose of this utility model is to provide an oil painting cloth stretcher, which can make the oil painting cloth stretched more smoothly.
本实用新型为实现上述目的,一种油画布绷架,包括画布绷板和设置在画布绷板四条边上的移动推板,画布绷板的表面为一个平整的平面且凸起于四条移动推板所在的平面,四条移动推板接触的部位为斜面,使四条移动推板首尾相连组成与画布绷板形状相同的平行四边形,画布绷板的背面设置齿轮凹槽,相邻移动推板上的两条导向柱分别层叠插在齿轮凹槽四周的画布绷板侧壁滑道内,相邻移动推板上的推动板分别贯穿的导向套分别层叠贯穿画布绷板侧壁,导向套的截面为与推动板形状相同,均为长方形,齿轮凹槽的中心通过摇把贯穿并固定有一个驱动齿轮,驱动齿轮外部还设置有十字架固定板,十字架固定板的四条边则分别固定在齿轮凹槽的侧壁上,摇把的内端插在画布绷板内,摇把还贯穿十字架固定板,使驱动齿轮能在齿轮凹槽和十字架固定板之间转动,推动板的内端分别固定有齿轮齿,各推动板的齿轮齿分别与驱动齿轮相啮合,每块移动推板的上表面分别通过多个固定螺栓固定有一片画布夹板,画布绷板背面齿轮凹槽的外沿设置有四条支撑画布绷板的支撑腿。In order to achieve the above purpose, the utility model provides an oil canvas stretching frame, which comprises a canvas stretching plate and movable push plates arranged on the four sides of the canvas stretching plate. The plane where the board is located, the parts where the four moving push boards contact are inclined planes, so that the four moving push boards are connected end to end to form a parallelogram with the same shape as the canvas stretch board. The two guide columns are stacked and inserted in the slideway of the side wall of the canvas stretcher around the gear groove, and the guide sleeves respectively penetrated by the push plates on the adjacent moving push plates are respectively stacked and penetrate the side wall of the canvas stretcher. The cross section of the guide sleeve is as follows: The shape of the push plates is the same, they are all rectangular. The center of the gear groove runs through and is fixed with a driving gear. The outside of the driving gear is also equipped with a cross fixing plate, and the four sides of the cross fixing plate are respectively fixed on the sides of the gear groove. On the wall, the inner end of the crank is inserted into the canvas stretcher, and the crank also runs through the cross fixing plate, so that the driving gear can rotate between the gear groove and the cross fixing plate, and the inner ends of the pushing plate are respectively fixed with gear teeth, The gear teeth of each push plate are respectively meshed with the drive gear, and the upper surface of each moving push plate is respectively fixed with a piece of canvas splint by a plurality of fixing bolts, and four supporting canvas stretch plates are arranged on the outer edge of the gear groove on the back of the canvas stretch plate the supporting legs.
通过以上设置,本实用新型的一种油画布绷架,通过四条画布夹板将画布的四条边压在移动推板上,转动摇把使驱动齿轮转动,驱动齿轮转动同时驱动四条推动板向外运动,推动板再分别推动每条移动推板向外扩张,使固定在四条移动推板上的画布四条边同时拉紧,由于画布绷板的表面凸起于四条移动推板所在的平面,这样便会使画布在画布绷板的表面绷的更紧,使画布在平整的画布绷板表面绷开,画布四条边同时拉紧,再加上画布在平整的画布绷板表面绷开,这样使画布绷的更平整,更有利于作画;画布的四条边是通过画布夹板压在移动推板上的,画布夹板的压力来自拧紧的固定螺栓,而固定螺栓没有贯穿画布,即画布的固定是固定螺栓通过压板间接作用压在移动推板上的,这样做的好处是,一旦摇把转动力度过大,四条移动推板向外扩张的范围超过画布的伸展范围,画布的四条边就会从画布夹板和移动推板的缝隙中脱落,进而保证画布不被绷破。Through the above settings, the canvas stretcher of the utility model presses the four sides of the canvas on the moving push plate through the four canvas splints, turns the handle to rotate the driving gear, and the driving gear rotates to drive the four pushing plates to move outward at the same time , the push plate pushes each moving push plate to expand outwards, so that the four sides of the canvas fixed on the four moving push plates are tensed at the same time. The canvas will be stretched more tightly on the surface of the canvas stretcher, so that the canvas will be stretched on the flat surface of the canvas stretcher, and the four sides of the canvas will be tensed at the same time, and the canvas will be stretched on the flat surface of the canvas stretcher, so that the canvas The tension is smoother, which is more conducive to painting; the four sides of the canvas are pressed on the moving push plate by the canvas splint. The pressure of the canvas splint comes from the tightened fixing bolts, and the fixing bolts do not penetrate the canvas, that is, the fixing of the canvas is the fixing bolts. The advantage of this is that once the rotation force of the handle is too large, the expansion range of the four moving push plates exceeds the stretching range of the canvas, and the four sides of the canvas will be separated from the canvas splint. And the gap between the moving push plate and the moving push plate, so as to ensure that the canvas will not be broken.
