Description

A kind of canvas straining frame
Technical field
It the utility model is related to a kind of canvas straining frame.
Background technology
Taut canvas is one of important work before oil painting drawing, main purpose be make the canvas of fold by tighten and Become smooth, be so advantageous to draw a picture, and can guarantee that the quality of oil painting.Taut canvas is mainly realized by taut frame at present, and stretch tight frame The actually framework of quadrangle, there is following step:
1st, the latitude and longitude of canvas and the side of inside casing four are ajusted, otherwise crooked woven design will influence the skin texture aesthetic feeling of picture (size of canvas typically should be bigger 4~5cm than inside casing), then all painting canvas are cut down.
2nd, painting canvas is first temporarily fixed inside casing corner with several nails or drawing pin, makes its holding parallel with inside casing, Purpose is crooked also for not produced when being maintained at taut cloth.
3rd, straight line is drawn along the exterior angle on the side of inside casing four on painting canvas with charcoal, so can later stretches tight and help to grasp when drawing Sense of propriety, firmly consistent can also be kept.
When the 4th, following closely painting canvas nail should since at the outer side center of inside casing long side, then in corresponding another leader pin second, Then two short sides are followed closely in the same way.At this moment painting canvas center can form a rhombus fold, then be handed over by the order on four sides Direction is pitched to carry out.
Then traditional taut frame draws painting canvas to realize and tightened when in use, it is necessary to withstand painting canvas with nail by manpower Painting canvas, such people's is firmly unavoidable uneven, once and overexertion also tear painting canvas to shreds since the position of nail painting canvas, cause The unnecessary loss of painting canvas.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of canvas straining frame, canvas straining can be made It is more smooth.
The utility model to achieve the above object, a kind of canvas straining frame, including painting canvas toggling and be arranged on painting canvas toggling Mobile push pedal on four edges, a smooth plane is in the surface of painting canvas toggling and is raised in putting down where four mobile push pedals Face, the position of four mobile push pedals contacts be inclined-plane, make four mobile push pedals join end to end form it is identical with painting canvas toggling shape Parallelogram, the back side of painting canvas toggling sets gear recesses, and two leads in adjacent mobile push pedal are laminated slotting respectively In the painting canvas toggling side wall slideway of gear recesses surrounding, the guide sleeve that the pushing plate in adjacent mobile push pedal extends through is distinguished Stacking run through painting canvas toggling side wall, and the section of guide sleeve is identical with promotion plate shape, is rectangle, the center of gear recesses Run through by crank and be fixed with a drive gear, be additionally provided with cross fixed plate outside drive gear, cross is fixed The four edges of plate are then separately fixed in the side wall of gear recesses, and the inner of crank is inserted in painting canvas toggling, and crank also extends through ten Cabinet frame fixed plate, drive gear is set to be rotated between gear recesses and cross fixed plate, the inner of pushing plate is fixed respectively There is gear teeth, the gear teeth of each pushing plate is meshed with drive gear respectively, and the upper surface of every piece of mobile push pedal is respectively by more Individual fixing bolt is fixed with a piece of painting canvas clamping plate, and the outer of painting canvas toggling back side gear recesses is provided with four support painting canvas togglings Supporting leg.
By arrangement above, a kind of canvas straining frame of the present utility model, by four painting canvas clamping plates by four of painting canvas While being pressed in mobile push pedal, rotating crank rotates drive gear, and drive gear rotates drives four pushing plates to outward transport simultaneously Dynamic, pushing plate promotes every mobile push pedal to expand outwardly respectively again, makes the painting canvas four edges that are fixed in four mobile push pedals same When tense, because the rat of painting canvas toggling is in the plane where four mobile push pedals, will so painting canvas is stretched tight in painting canvas The surface of plate is stretched tight tighter, painting canvas is stretched tight on smooth painting canvas toggling surface and is opened, painting canvas four edges tense simultaneously, along with painting canvas Stretch tight and open on smooth painting canvas toggling surface, painting canvas is stretched tight more smooth, be more beneficial for drawing a picture;The four edges of painting canvas are to pass through Painting canvas clamping plate is pressed in mobile push pedal, and the pressure of painting canvas clamping plate is from the fixing bolt tightened, and fixing bolt does not extend through The fixation of painting canvas, i.e. painting canvas is that fixing bolt is pressed in mobile push pedal by pressing plate indirectly-acting, advantage of this is that, one Denier crank rotatory force is spent greatly, and the scope that four mobile push pedals expand outwardly exceedes the extending range of painting canvas, the four edges of painting canvas It will be come off from the gap of painting canvas clamping plate and mobile push pedal, and then ensure painting canvas not by taut broken.
