[0048] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] like Figure 1-3 As shown, a photo frame according to a preferred embodiment of the present application includes a frame body 1, a base 2, and a connecting column 3. The frame body 1 has a display hole 11 in the middle for mounting a photo; the base 2 has a connecting hole 211; the connecting column 3 is fixed to the lower end of the frame body 1 and is removably inserted into the connecting hole 211. Specifically, the connecting column 3 includes two elastic columns 31 arranged opposite each other, with a gap 315 between at least the lower portions of the two columns 31, and the two columns 31 are movable relative to each other. That is, a gap 315 can exist between the two columns 31 as a whole, and the gap 315 can be the same or gradually increase from top to bottom; or the gap 315 can exist only at the lower portions between the two columns 31, while there is no gap at the upper and middle portions; or the gap 315 can exist at both the lower and middle portions between the two columns.

[0050] The outer wall of the lower end of the column is provided with an anti-slip protrusion protruding radially away from the column;

[0051] By pressing the two columns, the connecting column can be inserted into or pulled out of the connecting hole; and when the connecting column is inserted into the connecting hole, the anti-drop protrusion abuts against the outer edge of the lower end of the connecting hole.

[0052] The photo frame based on the above technical features is provided with a connecting column 3 at the lower end of the frame body 1. The connecting column 3 includes two elastic columns 31 arranged opposite to each other. There is a gap 315 between the lower parts of the two columns 31 and they can move relatively. At the same time, a connecting hole 211 is provided on the base 2. When the base 2 needs to be connected to the frame body 1, it is only necessary to relatively press the lower parts of the two columns 31 so that the two are relatively close to each other, and then insert the connecting hole 211. After insertion, the two columns 31 are reset and fit with the inner wall of the connecting hole 211 to achieve the fastening of the connecting column 3 and the base 2. The two posts 31 are connected, thereby realizing the connection between the frame body 1 and the base 2; when the frame body 1 needs to be removed from the base 2, the lower parts of the two posts 31 are also pressed relatively tightly to realize the separation of the posts 31 from the inner wall of the connecting hole 211, and then the posts 31 are pulled out from the connecting hole, that is, the separation of the frame body 1 and the base 2 is realized, thereby realizing the detachable connection between the frame body 1 and the base 2. When packaging is required, the frame body 1 and the base 2 are separated, which is not only convenient for packaging, but also the frame 1 and the base 2 are not connected after separation, and will not be damaged during transportation.

[0053] like Figure 2 、 5 6, in this application, in order to ensure the strength of the column 31 and facilitate installation, the preferred embodiment of the present application is that there is a gap between the two columns 31 as a whole, and the gap gradually increases from top to bottom, specifically:

[0054] The frame 1 is formed by splicing two frame units 12, and the two columns 31 are arranged in a one-to-one correspondence with the two frame units 12. The outer surface of the column 31 includes a contact surface 311 and an adjustment surface 312. The contact surface 311 is arc-shaped and fits the inner wall of the connecting hole 211. The adjustment surface 312 is a plane and is tilted toward the vertical plane. The upper end of the adjustment surface 312 is flush with the inner surface of the frame unit 12, so that the upper end surface of the column 31 can be semicircular (defined as the first semicircle). After the two columns 31 are spliced, their upper end surfaces just fit together to form a circle, so that the upper end surface of the column 31 can be made into the largest area, thereby ensuring the strength of the column 31 to the greatest extent. However, if the spacing between the two columns 31 from top to bottom is the same, since the connecting column 3 needs to be inserted into the connecting hole 211, the radius of the abutting surface 311 of the connecting column 3 needs to be limited by the connecting hole 211, so that the upper end surface of the column 31 cannot form a semicircle, and its area will be smaller than the first semicircle, so that the overall strength of the column 31 will be reduced.

[0055] Also see the attached Figure 3As can be seen from the above, a V-shaped gap 315 is formed between the adjustment surfaces 312 of the two columns 31 of the present application, and the spacing between the two adjustment surfaces 312 gradually increases in the direction away from the frame 1. In order to ensure the connection stability between the connecting column 3 and the connecting hole 211, the outer wall of the lower end of the column 31 is provided with an anti-slip protrusion 32 radially protruding in the direction away from the column 31 to prevent the connecting column 3 from being separated from the connecting hole 211 when disassembly is not required. Specifically, the base 2 includes a base body 22 and a mounting seat 21 arranged on the base body 22. The connecting hole 211 is arranged on the mounting seat 21 and passes through the upper and lower ends of the mounting seat 21. Preferably, the mounting seat 21 is cylindrical. When the connecting column 3 is inserted into the connecting hole 211, the anti-slip protrusion 32 abuts against the lower end surface of the mounting seat 21, thereby ensuring the connection stability between the lower end of the connecting column 3 and the lower end of the mounting seat 21. At the same time, to fully ensure the connection stability between the frame 1 and the base 2, it is also necessary to further ensure that the upper end of the connecting column 3 can be limited. In the present application, the column 31 includes a connecting portion 313 and an anti-slip portion 314. The other end of the connecting portion 313 is connected to the frame 1. The anti-slip protrusion 32 is arranged on the outer wall of the anti-slip portion 314. The height of the mounting seat 21 is the same as the height of the connecting portion 313. When the connecting column 3 is inserted into the connecting hole 211, the upper end face of the mounting seat 21 abuts against the lower end face of the frame 1. Thus, when the connecting column 3 is fully connected to the mounting seat 21, the anti-slip protrusion 32 abuts against the lower end face of the mounting seat 21, and the upper end face of the mounting seat 21 abuts against the frame 1, thereby completely clamping the connecting column 3 between the anti-slip protrusion 32 and the frame 1, ensuring the stability between the frame 1 and the base 2.

[0056] In addition, to further enhance the overall strength and stability of the photo frame, the upper end surface of the mounting seat 21 is flush with the upper end surface of the base body 22. Therefore, after installation, the upper end surface of the base body 22 also abuts the lower end surface of the frame body 1, further ensuring overall stability. Preferably, the base body 22 includes a cylindrical support portion and a frustum-shaped connecting portion. The lower end of the support portion is used for support, and the mounting seat 21 is disposed at the center of the connecting portion.

[0057] On the other hand, when the anti-slip protrusion 32 is provided, it is necessary to ensure that when the lower ends of the two columns 31 are relatively pressed together during the disassembly process, the anti-slip protrusion 32 can be detached from the lower end surface of the mounting seat 21. In this case, the larger the distance that the lower end of the column 31 can move, the better. Therefore, the present application sets the upper end of the adjustment surface 312 of the column 31 to be flush with the inner surface of the frame unit 12, which can achieve the maximum length of the adjustment surface 312, thereby achieving the maximum distance that the lower end of the column 31 moves when the adjustment surface 312 is deflected at the same angle, thereby facilitating the installation and disassembly between the connecting column 3 and the connecting hole 211.

[0058] Generally, the length L of the column 31 is 10 to 20 mm to meet the connection requirements, and 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, etc. At the same time, in order to ensure the strength of the column 31 as much as possible, the inclination angle of the adjustment surface 312 needs to be as small as possible. Taking all factors into consideration, if the angle between the two adjustment surfaces 312 is a, the value range of a can be 6 to 9°, such as 6.5°, 7°, 7.5°, 8°, 8.5°, etc.

[0059] like Figure 10 As shown, in this application, since a V-shaped gap is formed between the adjustment surfaces 312 of the two columns 31, that is, there is only one gap on the lower end surface of the connecting column 3, the lower end surfaces of the two columns 31 can only be relatively close to each other in one direction (as shown in the attached figure). Figure 10 The length of the lower end face of the connecting column 3 in the X direction remains unchanged, and since the anti-slip protrusion 32 is provided at the lower end of the column 31, the anti-slip protrusion 32 will interfere with the connecting column 3 and the base 2 in the X direction when the connecting column 3 is disassembled, making it difficult for the connecting column 3 to be pulled out from the connecting hole 211. To solve this problem, two disassembly grooves 212 are provided on the side walls of the mounting seat 21 of the present application, and the disassembly grooves 212 extend along the length direction of the mounting seat 21 to the lower end face of the mounting seat 21; the two columns 31 are symmetrical about a symmetry plane, and the plane formed by the center lines of the two disassembly grooves 212 is the center plane. When the frame 1 is disassembled from the base 2, the symmetry plane coincides with the center plane. Therefore, when disassembling, the base 2 or the frame 1 is first rotated relative to each other so that the symmetry plane coincides with the center plane, and then the lower ends of the two columns 31 are relatively pressed so that the lower ends of the two columns 31 are relatively close in the Y direction. Then, a force is applied to the frame 1 to separate it from the base 2. At this time, the anti-slip protrusions 32 at both ends of the connecting column 3 in the X direction will move upward along the disassembly groove 212, making it easier for the connecting column 3 to be separated from the mounting seat 21.

[0060] like Figure 8 、 9 As shown, at the same time, in order to further ensure the smoothness of installation and disassembly between the frame 1 and the base 2, the connecting hole 211 can be set to a truncated cone shape with a larger upper part and a smaller lower part, so that during the separation of the connecting column 3 from the connecting hole 211, the distance between the outer wall of the connecting column 3 and the inner wall of the connecting hole 211 will become larger and larger, and the disassembly will be smoother. During the installation process, since the upper end of the connecting hole is large, the connecting column 3 is also convenient for docking with the connecting hole 211, and the installation is also more convenient. The outer surface of the connecting column 3 can be tilted or not. If tilted, it can be the same as the tilt angle of the connecting hole 211. Preferably, the taper of the connecting hole 211 is b, and b is 5 to 7°, such as 5.1°, 5.2°, 5.5°, 5.8°, 6°, 6.1°, 6.2°, 6.8°, etc., that is, after installation, the outer wall of the connecting column 3 is completely in contact with the inner wall of the connecting hole 211. If the outer surface of the connecting column 3 is not tilted, it is only necessary to ensure that the outer surface of the connecting column 3 is partially in contact with the inner wall of the connecting hole 211. Under the premise that the anti-slip protrusion 32 and the upper end surface of the mounting seat 21 are in contact with the frame 1, it is sufficient to ensure the stability of the connection between the frame 1 and the base 2.

[0061] like Figure 4 As shown, in this embodiment, since the frame 1 is composed of two frame units 12, when installing a photo, the frame 1 can be disassembled first, and then the photo can be installed. However, in normal use, to protect the installed photo, two transparent protective sheets 4, such as glass or plastic, are generally provided inside the frame 1 corresponding to the display holes 11. A cavity for installing the photo is formed between the two protective sheets 4, thereby providing good protection for the photo. Therefore, if the frame 1 is disassembled when installing photos, the corresponding protective sheet 4 also needs to be disassembled. After placing the photos, it needs to be assembled again, which is relatively cumbersome. Therefore, in this application, in order to facilitate the installation of photos in the accommodating cavity, the inner wall of the display hole 11 is provided with a snap-in groove 14, and the periphery of the protective sheet 4 is snap-fitted into the snap-in groove 14; the upper end of the frame 1 is provided with a plug-in groove 15, and the plug-in groove 15 is communicated with the accommodating cavity, so as to realize the installation of photos into the accommodating cavity through the plug-in groove 15, that is, when installing photos normally, photos can be installed directly from the plug-in groove, and installing photos is simple and convenient.

[0062] However, if you need to replace the photo, you may not be able to directly remove the old photo from the insertion slot 15. In this case, you can remove it by disassembling the frame 1. Specifically, the two frame units 12 are connected by multiple sets of connecting components 13. That is, when you need to replace the photo, you can separate the two frame units 12, remove the photo, and then reassemble them. After reassembly, you can install the new photo through the insertion slot 15.

[0063] like Figure 2 、 7 As shown, at the same time, to facilitate the disassembly and assembly between the two frame units 12, the connecting assembly 13 includes a clamping seat 131 and a clamping column 132. The clamping seat 131 is provided with a clamping hole connected to the clamping column 132. That is, the clamping columns 132 of multiple groups of the connecting assemblies 13 are connected to the corresponding clamping holes to achieve the assembly between the two frame units 12; when the clamping columns 132 of the connecting assembly 13 are separated from the clamping holes, the frame 1 can be disassembled, and the installation and disassembly of the frame 1 are simple and convenient. In the specific setting, it is only necessary to ensure that the clamping seat 131 of the connecting assembly 13 of the same group is set on one of the frame units 12, and the clamping column 132 is set on the other frame unit 12. Therefore, for multiple groups of the connecting components 13 , only the clamping column 132 or only the clamping seat 131 may be provided on one frame unit 12 , or both the clamping seat 131 and the clamping column 132 may be provided partially.

[0064] It should be noted that, in this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0065] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0066] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
