Description

Technical Field

[0001] The utility model relates to the field of picture frames, in particular to an oil painting picture frame. Background Art

[0002] Oil painting is a painting genre made by mixing pigments with quick-drying vegetable oils (such as linseed oil, poppy oil, walnut oil, etc.) on canvas (linen), cardboard or wooden board. With the covering power and transparency of pigments, it can fully display the depicted object, with rich colors and strong three-dimensional texture.

[0003] Currently, when most oil paintings are framed, edge stretching is usually carried out first, that is, the white edge reserved at the edge of the oil painting is wound around the wooden inner frame. After being straightened and tightened, it is fixed at the back with a nail gun, and then the canvas fixed on the inner frame is packaged with an outer frame. This method has some deficiencies: for example, 1. A nail gun is needed for edge stretching. Ordinary people usually do not have such tools as nail guns, resulting in difficulty in fixing the canvas during edge stretching, difficult operation, and it is easy to have wrinkles after edge stretching without rich operation experience; 2. The existence of the inner frame makes the framed oil painting thick and heavy; 3. The fixed connection structure between the canvas and the inner frame makes it difficult to reframe the oil painting and the inner frame repeatedly. Content of the Utility Model

[0004] The purpose of the utility model is to provide an oil painting picture frame, which helps to solve the problems that some existing picture frame structures lead to high requirements for oil painting framing operations, poor repeatability, and the framed finished product being thick and heavy.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An oil painting picture frame includes a front frame. The front frame is a rectangular frame structure, and a display window is formed in the middle. A rear plate is detachably connected to the rear side of the front frame. A clamping groove is provided at the inner end of the rear side end face of the front frame near the display window. A clamping member adapted to the edge structure of each edge of the front frame is arranged in the clamping groove. The clamping member includes a first pressing block connected to the front frame and a second pressing block connected to the rear plate. The adjacent sides of the first pressing block and the second pressing block are provided with a stretching end face with an inclined surface structure. After the first pressing block and the second pressing block follow the fitting connection of the front frame and the rear plate, the stretching end faces on the first pressing block and the second pressing block can be mutually attached and clamp and stretch the canvas.

[0007] On the basis of the above technical scheme, one first pressing block and one second pressing block distributed front and back form a set of clamping members. The first pressing block and the second pressing block in each set of clamping members are respectively parallel to the strip-shaped flange structure of each edge of the front frame.

[0008] On the basis of the above technical scheme, a corner is provided on the stretching end face, and the corner makes the clamping gap of the clamping end face form a folding line anti-loosening structure.

[0009] On the basis of the above technical solution, a shaping end face is provided on one side of the stretching end face close to the display window, and the shaping end face is a flat end face parallel to the display face.

[0010] On the basis of the above technical solution, an elastic gasket is provided on the stretching end face of the first pressing block and / or the second pressing block. The elastic gasket is a strip-shaped flange structure and is parallel to the long side direction of the first pressing block or the second pressing block.

[0011] On the basis of the above technical solution, a plurality of sucker grooves are evenly distributed on the elastic gasket.

[0012] On the basis of the above technical solution, the connection structures between the first pressing block and the front frame, and between the second pressing block and the rear plate are both detachable connection structures.

[0013] On the basis of the above technical solution, the connection structures between the first pressing block and the front frame, and between the second pressing block and the rear plate both adopt a connection structure of bolts and threaded holes, and the bolts after locking are located inside the elastic gasket.

[0014] Compared with the prior art, the utility model has at least the following advantages:

[0015] 1. By setting a simple front frame and rear plate structure, the overall structure of the utility model is light, and there is no need for a traditional inner frame, achieving the effect of being thinner and lighter, which can meet the placement or hanging requirements of more scenarios.

[0016] 2. The utility model realizes the assembly of the picture frame by using the abutting combination between the front frame and the rear plate, and uses the clamping parts between the two to complete the stretching and fixing of the canvas during the assembly process, making the mounting operation of the oil painting convenient and easy, without the need to use tools such as nail guns, which helps to solve the problem that the mounting operation requirements of some existing picture frame structures for oil paintings are high.

[0017] 3. The utility model adopts a detachable front frame and rear plate, as well as a non-locking canvas stretching and clamping structure, which enables both the picture frame and the oil painting to be independently disassembled and assembled repeatedly, which is beneficial to solving the problem of poor repeatability of existing oil painting mounting.

When an element is considered to be "connected" to another element, it can be directly connected to an element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0027] Embodiment 1: Please refer to Figures 1 to 3 , this embodiment discloses an oil painting frame, including a front frame 1 and a rear plate 2 that are split - type and can be spliced into a whole. The front frame 1 is a rectangular frame structure, and a display window a is formed in the middle thereof. The rear side of the front frame 1 is detachably connected to the rear plate 2. In this embodiment, a countersunk connection hole 3 is provided between the front frame 1 and the rear plate 2 for cooperating with bolts to complete the locking connection between the two. After the front frame 1 and the rear plate 2 are aligned and spliced front - to - back, they form the main structure of the picture frame, and the display window a is used to expose the core area of the oil painting for picture display.

[0028] Combined with Figure 2 as shown, on the inner side end of the rear side end face of the front frame 1 close to the display window a, there is a clamping groove 4. The clamping groove 4 is a rectangular annular groove hole structure and is arranged around the outer edge of the display window a. The presence of the clamping groove 4 makes an annular chamber formed at the connection between the front and the rear plate 2.

[0029] A clamping member 5 adapted to the edge structure of each edge of the front frame 1 is arranged in the clamping groove 4. Refer to Figure 3, the clamping member 5 specifically includes a first pressing block 51 connected to the front frame 1 and a second pressing block 52 connected to the rear plate 2. One first pressing block 51 and one second pressing block 52 distributed front and rear form a set of clamping members 5. The first pressing block 51 and the second pressing block 52 in each set of clamping members 5 are respectively strip-shaped flange structures parallel to the edges of the front frame 1. That is to say, there are 4 sets of clamping members 5 corresponding to the up, down, left, and right directions of the clamping grooves 4.

[0030] Furthermore, a stretching end face b with an inclined surface structure is provided on the adjacent sides of the first pressing block 51 and the second pressing block 52. After the first pressing block 51 and the second pressing block 52 follow the fitting connection of the front frame 1 and the rear plate 2, the stretching end faces b on the first pressing block 51 and the second pressing block 52 can be mutually attached and clamp and stretch the canvas, so that the edge of the canvas extends and stretches outward after being clamped, making it present a suitable flat state. During specific use, first place the front frame 1 face down and the clamping groove 4 face up on the table, then align and lay the canvas flat, and then press the rear plate 2 down after pressing it in the installation position, so that the rear plate 2 is spliced with the front frame 1. During this process, the stretching end faces b on the first pressing block 51 and the second pressing block 52 will clamp and fix the white edge of the canvas, and a horizontal pulling force will be formed with the splicing after clamping, and the area of the canvas inside the stretching end face b will be stretched and pulled outward, realizing a convenient mounting operation.

[0031] Furthermore, in order to improve the stretching effect and prevent the canvas from easily loosening when being stretched, a corner c is provided on the stretching end face b, and the corner c makes the clamping gap of the clamping end face form a folded-line anti-loosening structure.

[0032] In order to make the oil painting keep a flat state in the display window a after being mounted, a shaping end face d is provided on the side of the stretching end face b close to the display window a. The shaping end face d is a flat end face parallel to the display surface. After the front frame 1 and the rear plate 2 are attached, the flat end face can shape and clamp the canvas inside the stretching end face b, so that the canvas inside keeps a suitable and stable flat state, reducing the occurrence of the situation that the oil painting tilts after being mounted.

[0033] Embodiment 2: On the basis of Embodiment 1, in this embodiment, an elastic gasket 6 is provided on the stretching end face b of the first pressing block 51 and the second pressing block 52. As shown in Figure 4 shown, Figure 4 taking the second pressing block 52 as an example for display. The elastic gasket 6 is a strip-shaped flange structure and is parallel to the long side direction of the first pressing block 51 or the second pressing block 52. The elastic gasket 6 is made of rubber material, and its outer end face is used to elastically abut against the canvas when clamping the canvas, thereby increasing the friction coefficient during clamping, and improving the stretching effect by further enhancing the anti-loosening and anti-slip effects.

[0034] Furthermore, as shown in Figure 5As shown, a number of sucker grooves 61 are evenly distributed on the elastic gasket 6. The sucker groove 61 is a tapered hole structure with a wider outer width and a narrower inner width. It will undergo corresponding deformation under pressure and form a firm adsorption structure, enabling the pressing block to firmly fit and clamp the canvas.

[0035] Embodiment 3: On the basis of Embodiment 2, in this embodiment, the connection structures between the first pressing block 51 and the front frame 1, and between the second pressing block 52 and the rear plate 2 are all detachable connection structures. This enables the first pressing block 51 and the second pressing block 52 to be replaced and maintained after long-term use, or different specifications or materials of pressing block accessories can be selected according to actual mounting requirements.

[0036] Specifically, the connection structures between the first pressing block 51 and the front frame 1, and between the second pressing block 52 and the rear plate 2 both adopt the connection structure of bolts and threaded holes. The locked bolts are located inside the elastic gasket 6. When clamping the canvas, the canvas first receives the elastic abutment of the elastic gasket 6. As the clamping force increases, the bolts will form a rigid scattered-point abutment structure, combining rigidity and flexibility to improve the clamping effect. Figure 6 As shown, a number of through holes 62 are provided on the elastic gasket 6. The through holes 62 penetrate the elastic gasket 6. Threaded through holes 62 are correspondingly provided directly below the through holes 62 on the first pressing block 51 and the second pressing block 52, which are used to cooperate with the bolts to complete the disassembly and assembly operations of the first pressing block 51 and the second pressing block 52.
