[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A foldable picture frame that is easy to transport, comprising a foldable annular frame 1 and a foldable back panel 2, the annular frame 1 folds left and right, the annular frame 1 is composed of two U-shaped plates arranged left and right, the rear sides of the two U-shaped plates are connected by a plurality of first hinges, the front side wall of the back panel 2 is provided with a groove 12 for accommodating the first hinges, the back panel 2 is folded up and down, the back panel 2 is composed of two folding plates arranged up and down, the rear sides of the two folding plates are connected by a plurality of second hinges, the folding directions of the annular frame 1 and the back panel 2 are different, so when the annular frame 1 and the back panel 2 are connected and installed, they can play a mutual blocking role, so that they can be stably in the unfolded state;

[0023] The back plate 2 is connected to the rear side wall of the annular frame 1 by a plurality of first screws 3. The rear side wall of the annular frame 1 is provided with a plurality of plug holes, and the inner side walls of the plurality of plug holes are provided with threaded holes. A plurality of annular plug blocks 4 are provided through the back plate 2. The plurality of annular plug blocks 4 are inserted into the corresponding plug holes, so that the back plate 2 and the annular frame 1 can be preliminarily connected and aligned. The first screws 3 pass through the annular plug blocks 4 and are threadedly locked in the threaded holes. The back plate 2 can be stably connected to the annular frame 1 by the first screws 3.

[0024] The inner side wall of the annular frame 1 is fixedly connected with an annular baffle 5 adapted thereto, and the annular baffle 5 can be folded along with the annular frame 1. The annular baffle 5 is composed of two U-shaped baffles adapted to the annular frame 1, and the two U-shaped baffles can respectively rotate and fold along with the two U-shaped plates. The setting of the annular baffle 5 can block the painting and prevent it from falling off from the annular frame 1. The front side wall of the back plate 2 is connected to two supporting plates 8 through a plurality of telescopic parts, and the telescopic parts include an annular sleeve 6 fixedly connected to the front side wall of the back plate 2, and the annular sleeve 6 The inner sliding connection is equipped with a sliding rod 7 adapted thereto, and a plurality of springs are connected between the sliding rod 7 and the inner side wall of the annular sleeve 6. The springs are elastic springs, which can push the sliding rod 7 outward from the annular sleeve 6 in a natural state. The support plate 8 is fixedly connected to the ends of the two sliding rods 7 on the same horizontal line and extends into the annular frame 1. The movement of the annular sleeve 6 outward from the sliding rod 7 can drive the support plate 8 to move into the annular frame 1, and then the support plate 8 and the annular baffle 5 can work together to clamp and fix the painting, and install the painting in the annular frame 1;

[0025] The rear side wall of the back panel 2 is symmetrically provided with two supporting components, and the supporting components include a mounting block 13 fixedly connected to the rear side wall of the back panel 2 by a second screw. The second screw connection facilitates installation and disassembly. The bottom of the mounting block 13 is fixedly connected to an L-shaped support plate 9, and the side wall of the L-shaped support plate 9 is fixedly connected to a connecting block 10. The side wall of the connecting block 10 is rotatably connected to a leg 11 located in the L-shaped support plate 9 and abutting against the side wall of the L-shaped support plate 9. The leg 11 rotates to form an angle with the annular frame 1, so that the annular frame 1 can be placed on a desktop for use. The L-shaped support plate 9 can limit the leg 11, so that the leg 11 cannot continue to rotate and unfold when it abuts against the L-shaped support plate 9, thereby ensuring the stability of the annular frame 1 when it is placed.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] In the utility model, the foldable picture frame which is easy to transport, when the picture frame needs to be transported, the second screw is unscrewed to disassemble the support assembly from the back plate 2, and the first screw 3 is unscrewed to separate the back plate 2 from the annular frame 1, so that the back plate 2 can be turned upside down and folded, and the annular frame 1 can be turned left and right and folded, thereby reducing the occupied area and facilitating the transportation after they are separately wrapped;

[0028] When the picture frame needs to be assembled for use, the annular frame 1 and the back plate 2 are unfolded, the painting is placed in the annular frame 1 and blocked by the annular baffle 5, so that the annular plug block 4 on the front side of the back plate 2 is inserted into the corresponding socket on the rear side of the annular frame 1, and the back plate 2 can be preliminarily connected with the annular frame 1, and the first screw 3 is passed through the annular plug block 4 and is threadedly connected with the threaded hole inside the socket, and the back plate 2 is stably fixed on the rear side of the annular frame 1. The annular frame 1 and the back plate 2 interfere with each other, so that the annular frame 1 and the back plate 2 cannot be rotated and folded, and are in a stable unfolded state. The spring pushes the sliding rod 7 to move outside the annular sleeve, and then the support plate 8 can move toward the annular baffle 5, so that the support plate 8 and the annular baffle 5 can work together to clamp and fix the painting, which is convenient for displaying the painting. According to the use requirements, the mounting block 13 is installed on the rear side of the back plate 2 by the second screw, so that the support leg 11 is rotated to abut against the side wall of the L-shaped support plate 9, and a stable angle is formed between the annular frame 1 and the support leg 11, so that the picture frame can be placed on the desktop for use.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
