Problems solved by technology

At present, the inner frames of oil paintings are generally made of wood, and basically all wooden inner frames are specially made. For art creators, it is necessary to prepare a lot of picture frames of different sizes, which take up a large space and are very easy to carry. inconvenient
[0003] Although there are inner frames similar to folding and assembling functions on the market, due to their structural limitations, there are generally many and heavy parts, which are easy to lose and cannot be used normally and are not conducive to carrying around.
Secondly, due to the characteristics of oil paint, it takes a long time to dry completely (usually several weeks) after the creation is completed, and the paint is easy to stick the inner frame and the edge of the canvas, which will affect the quality of the painting. Various elements, long-term contact with the frame will corrode the frame and affect the service life of the frame
Finally, subject to geographical location, building environment, climatic conditions and other factors, the air humidity is also different, resulting in slight changes in the degree of tension of the canvas on the frame: if the air humidity is too high, in addition to affecting the drying of the paint At the same time, the speed may also cause the canvas to relax and cause the canvas to wrinkle after the paint dries; if the air humidity is too low, it may cause the canvas to be too tight, so that small or even visible cracks will appear after the paint dries

Embodiment 1

[0042] Such as figure 1 As shown, a portable adjustable oil painting inner frame disclosed by the present invention includes a frame 1, a fixed cavity 101 is formed in the frame 1, a fixed groove 102 arranged axially and communicated with the fixed cavity 1 is formed on the frame 1, the fixed cavity 101 is provided with a fixing strip 103, and the width of the fixing groove 102 is smaller than the width of the fixing strip 103; each side of the frame 1 is provided with two fractures 104, and each fracture 104 is provided with a first adjustment for adjusting the width of the fracture 104 Assembly 2; an intermediate rod 3 is provided on the inner side of each side of the frame 1 avoiding the fracture 104, and a second adjustment for adjusting the distance between the end of the intermediate rod 3 and the frame 1 is provided between each intermediate rod 3 and the frame 1 Assemblies 4, the positions of the middle rods 3 on the two sides of the frame 1 correspond to each other an...

Embodiment 2

[0050] Such as Image 6 with Figure 7 As shown, the difference between this embodiment and embodiment 1 is:

[0051] The connecting plate 303 is provided with a plurality of anti-vibration seats 304 arranged corresponding to the second adjustment seat 401 , and the anti-vibration seats 304 are provided with anti-vibration holes 305 matched with the ends of the second screw rod 403 .

[0052] control Figure 7 , taking the first support tube as an example, the outer walls of the first support tube 106 and the second support tube 302 are provided with several rib grooves 601 that cooperate with the ribs 6, and there are several rib grooves 601 between the ribs 6 and the rib grooves 601. The buffer assembly, the buffer assembly includes a number of dampers 602 evenly arranged at the bottom of the rib 6, the end of each damper 602 is fixedly connected with a buffer spring 603, and the other end of the buffer spring 603 is connected to the bottom of the rib groove 601; the first...

Embodiment 3

[0055] Such as Figure 8 As shown, the difference between this embodiment and embodiment 1 is:

[0056] The cross-section of the first cavity 105 is rectangular, and an isolation cavity 107 is arranged above the first cavity 105 relative to the fixed cavity 101 in the frame 1. The cross-section of the isolation cavity 107 is a right-angled trapezoid with the upper bottom at the left and the lower bottom at the right. The angle between the oblique waist of the section of the cavity 107 and the lower bottom is 80°. A connection cavity 108 is provided in the frame 1 on the left side of the first cavity 105 .

[0057] After many experiments, it has been proved that under the premise of ensuring the strength of the picture frame, the picture frame is controlled to the minimum size. When the angle between the slanted waist of the section of the isolation cavity and the lower bottom is greater than 85°, the distance between the picture frame and the canvas is less than 3mm. At leas...

Abstract

The invention discloses a portable adjustable oil painting inner frame. The portable adjustable oil painting inner frame comprises a frame. A fixing cavity is formed in the frame. A fixing groove is formed in the frame, wherein the fixing groove is formed in the axial direction and communicates with the fixing cavity. The fixing cavity is internally provided with a fixing strip. Each edge of the frame is provided with one or more fractures. Each fracture is provided with a first adjustment assembly, wherein each first adjustment assembly is used for adjusting the width of the corresponding fracture. The inner side of each edge of the frame is provided with one or more middle rods. A second adjustment assembly is arranged between each middle rod and the frame, wherein each second adjustmentassembly is used for adjusting the distance between the end of the corresponding middle rod and the frame. The portable adjustable oil painting inner frame is simple in structure; by means of the frame with the fractures, the effect that the size of the frame is adjustable is achieved, and various different use requirements are met; in the drying process, the edge of canvas cannot make contact with a painting frame, quality of a painting is guaranteed, and meanwhile, the service life of the painting frame is guaranteed; and the tightening degree of the canvas can be automatically adjusted according to variation of the humidity of air in the environment where the canvas is located, and quality of the painting is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of painting utensils, in particular to a portable adjustable oil painting inner frame. Background technique [0002] Oil painting is one of the main types of Western painting. The pigment attached to the picture has strong hardness. When the picture is dry, it can maintain its luster for a long time. Relying on the hiding power and transparency of the pigment, it can fully express the depicted object, with rich colors and strong three-dimensional texture. It is a kind of painting made on canvas, linen, cardboard or wooden board with quick-drying vegetable oil (linseed oil, poppy oil, walnut oil, etc.) The frame holds the canvas taut in place. At present, the inner frames of oil paintings are generally made of wood, and basically all wooden inner frames are specially made. For art creators, it is necessary to prepare a lot of picture frames of different sizes, which take up a large space and are very easy t...
