Description

A kind of picture frame that makes things convenient for the tensioning painting canvas

Technical field

The utility model relates to picture material field, relates in particular to oil painting picture frame field.

Background technology

Oil painting is a kind of common artistic expression, and Oil Painting carries out at special painting canvas usually, needs oil painting is fixed on the picture frame before drawing; In order to paint conveniently, also attractive in appearance for works are more had, painting canvas should be smooth, corrugationless, nothing depression.

Because the inherent characteristics of Oil Painting, the artist needs repeatedly to polish in production process, thick and heavy pigment often so that painting canvas since Action of Gravity Field to the picture frame central concave, both affected further creation, also affect the aesthetic feeling of works, just needed the tensioning painting canvas this moment; Because the cycle of creation is longer, creating a width of cloth works may need repeatedly tensioning painting canvas.The artist generally can solve by the re-tensioning painting canvas problem of painting canvas depression, fold at present, and this method wastes time and energy, and also causes easily painting canvas to damage.

The utility model content

The applicant for painting canvas in the Oil Painting process under the Action of Gravity Field of pigment, cave in, the problem of tensioning inconvenience during fold, a kind of picture frame that makes things convenient for the tensioning painting canvas is provided, it is simple in structure, easy to use, tensioning painting canvas several times, satisfy in the width of cloth oil painting process the repeatedly needs of tensioning painting canvas, make things convenient for the artist to create.

The technical solution of the utility model is as follows:

A kind of picture frame that makes things convenient for the tensioning painting canvas comprises inside casing, housing and cam pin, described inside casing and housing joggle; Have tongue-and-groove on the described inside casing lateral surface, have the hole of perforation on the flange of described tongue-and-groove both sides, described hole stays arc-shaped concave in the bottom surface of tongue-and-groove, and described cam pin is inserted in the described hole; The medial surface of described housing is provided with tenon; Described cam pin comprises pillar, and the height of pillar is greater than the thickness of described tenon; Described pillar two ends are connected with respectively disk, and described disk is coaxial, and described pillar is connected with disk is eccentric.

It is further characterized in that:

The cross section of described pillar is semilune;

One end of described cam pin is fluted; Described picture frame also comprises key, and the head of described key can insert in the described groove, and drives described cam pin rotation;

The outer surface of described pillar has anti-skidding lines.

The beneficial effects of the utility model are as follows:

Because the pillar arranged off-centre in the cam pin, thereby rotating eccentricity pin, housing can be ejected by described pillar, thereby the tensioning picture frame does not need to remount, and is easy to use, simple in structure; Described pillar surface is with the anti-slip veins road, prop up housing after cam pin can not rotate again, thereby can rotate continuously towards a direction several times, to realize the several times function of tensioning painting canvas, make things convenient for the artist deeply to create; Tensile force can be adjusted by the anglec of rotation of adjusting cam pin as required simultaneously, avoids damaging painting canvas.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment is described.

Such as Fig. 1, shown in Figure 3, the utility model comprises inside casing 4, housing 1 and cam pin 3, inside casing 4 and housing 1 joggle; Have tongue-and-groove 6 on inside casing 4 lateral surfaces, have the hole 7 of perforation on the flange 5 of tongue-and-groove 6 both sides, hole 7 stays semicircle concave surface 8 in the bottom surface of tongue-and-groove 6.The medial surface of housing 1 is provided with tenon 2.Cam pin 3 is inserted in the hole 7.

Such as Fig. 4, shown in Figure 5, cam pin 3 comprises pillar 11, and pillar 11 two ends are connected with respectively disk 10, two disks 10 coaxial arrangement of one,

pillar

11 and 10 eccentric connections of disk; There is the anti-skidding lines 12 of vertical direction on the surface of pillar 11.Certainly, anti-skidding lines 12 also can adopt grid-shaped or the form of other identical functions.

As shown in Figure 2, the height of pillar 11 should be slightly larger than the thickness of tenon 2, so that tenon 2 can be stuck between the disk 10 at cam pin 3 two ends, cam pin 3 is played position-limiting action, prevents that cam pin 3 from skidding off from hole 7.

Such as Fig. 2, shown in Figure 6, the cross section of pillar 11 is semilune, and the effect of this shaped cross is: when cam pin 3 rotated towards direction in 180 ° of scopes, the outer surface of spider 11 increased progressively to the distance of the axis of disk 10; Thereby when the operator turned in the same direction cam pin 3, painting canvas can be by continuously tensioning.Certainly, pillar 11 promotes housing 1 by eccentric center principle and moves, and its concrete shape can be not limited to the semilune described in the present embodiment, can be ellipse, pyriform even other shapes that needs.

Such as Fig. 4 and shown in Figure 7, an end of cam pin 3 has the groove 9 of triangular prism-shaped; Described picture frame also comprises key 13, and the nose shape of key 13 is identical with groove 9, can insert in the groove 9, and drive cam pin 3 rotations.Certainly, it is described triangular prism shaped that the shape of groove 9 is not limited to present embodiment, as long as groove 9 is identical with the nose shape of key 13, can cooperate rotation, and its technique effect is identical.Improvement to the nose shape of groove 9 and key 13 does not need the technical staff to pay creative thinking.

When using the utility model to create, painting canvas should be fixed on the outer peripheral face of housing 1; Fixedly should guarantee smooth, the corrugationless of painting canvas during painting canvas as far as possible.

When initial creation, the pillar 11 of cam pin 3 should be rotated in the semicircle concave surface 8, it is minimum that this moment, cam pin 3 stretched out the volume of concave surface 8, and housing 1 is minimum with the gap of inside casing 4.When through after a while creation, when painting canvas engenders depression, rotate cam pin 3 with key 13, pillar 11 can stretch out from semicircle concave surface 8 gradually, with housing 1 top laterally, thus the tensioning painting canvas; Adjust suitable rear taking-up key, because there is anti-skidding lines 12 on pillar 11 surfaces, cam pin 3 can not rotate, thereby can keep tensioning.When needing again tensioning, repeat said method and get final product.When creation is finished, in the time of need to taking off painting canvas, as long as pillar 11 is screwed in the concave surface 8 again, can take off painting canvas, this moment, painting canvas was subjected to tensile force hardly, thereby took off Shi Buhui and damage painting canvas.

More than describing is to explanation of the present utility model, is not the restriction to utility model.The utility model limited range is referring to claim, and in the situation of the utility model basic structure, the utility model can be done any type of modification.
