[0002] The traditional method of bi-fold photo frame is to put a piece of glass in the left and right frames, then put in the photo paper, and then install a paper backing board. There is only one hinge, which is neither beautiful nor strong. If the two-piece glass bi-fold photo frame is made of EVA strips, it is very easy to be deformed by friction, and the glass is easy to fall off. It is difficult for consumers to use it normally to replace and install their own photos. Such accessories are slow to install, inefficient, and there is a risk of glass falling off and injuring people; directly installing the shrapnel is also likely to cause the shrapnel to fall off and pop out, posing a risk of accidental injury.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0033] Reference Figures 1 to 7 , is an embodiment of the utility model, which provides a photo frame for convenient lens changing, two frames 100 are hinged to realize a double-fold photo frame, and the two frames 100 are clamped by a clamping assembly 200 to clamp the lens 101. Specifically, the frame 100 is provided with a clamping assembly 200 for clamping the lens 101, and the lens 101 is arranged on the frame 100. The clamping assembly 200 includes a mounting portion 201 and a clamping portion 202, and the two are an integrally formed structure. The mounting portion 201 is mounted on the inner side or the outer side of the frame 100, and the lens 101 is mainly clamped by the clamping portion 202. However, for the sake of aesthetics, the mounting portion 201 is generally mounted on the inner side of the frame 100, so that the lens 101 can be clamped after installation. Connected to the frame 100, when the lens 101 is pushed into the frame 100, the clamping part 202 is in rolling friction contact with the lens 101. During the process of clamping the lens 101, the clamping part 202 pushes the lens 101 in a rolling friction manner, which can facilitate the installation of the lens 101, and its outstanding feature is that the resistance is small. When the lens 101 is pulled out of the frame 100, the clamping part 202 is in static friction contact with the lens 101, which prevents the lens 101 from being easily taken out, so as to avoid the lens 101 falling off, and increase the pulling force to convert the static friction into rolling friction. By pulling the lens 101 with force, the static friction force of the clamping part 202 is converted into rolling friction, so that the lens 101 can be easily taken out to change the photo.

[0034] Specifically, the clamping portion 202 includes an elastic member 202a, an extrusion member 202b and a damping member 202c. The elastic member 202a is connected to the mounting portion 201 to provide sufficient elastic pressure to press the lens 101. The extrusion member 202b is connected to the elastic member 202a and is provided with a damping member 202c. The damping member 202c is mainly made of a soft material such as rubber and is sleeved in the extrusion member 202b and the symmetrically opened adapting groove 202b-1. The damping member 202c is in extrusion contact with the clamping lens 101 in the push / pull phase so that the damping member 202c rolls on the extrusion member 202b. The extrusion member 202b is provided with a pair of adapting grooves 202 b-1, the damping member 202c can roll on the extrusion member 202b by relying on the adapting groove 202b-1, just like a simple conveyor belt. The damping member 202c includes a damping sleeve 202c-1 and a damping strip 202c-2. The damping sleeve 202c-1 is sleeved on the adapting groove 202b-1. The outer surface of the damping sleeve 202c-1 is provided with damping strips 202c-2 at equal intervals. The damping strips 202c-2 are in frictional contact with the surface of the adapting groove 202b-1. The damping sleeve 202c-1 is in frictional contact with the surface of the extrusion member 202b. The damping effect is achieved by the friction force generated by the damping strip 202c-2 being carried by the rotation and contacting with the surface of the adapting groove 202b-1;

[0035] Further, such as Figure 6 As shown, the bottom of the damping strip 202c-2 is connected to the damping sleeve 202c-1, and the two are an integrally formed structure. When the damping strip 202c-2 is pushed into the lens 101, the damping strip 202c-2 moves in the damping sleeve 202c-1, and the first damping area 202c-2b of the damping strip 202c-2 is in frictional contact with the adapting groove 202b-1, so that the damping strip 202c-2 is compressed, the first damping area 202c-2b is in contact with the adapting groove 202b-1, the first damping area 202c-2b is squeezed, and the first damping area 202c-2b is squeezed and deformed, and the friction force decreases accordingly (usually, the friction force is proportional to the pressure, that is, the greater the pressure, the greater the friction force. This is because on the surfaces of two objects in contact, increasing the pressure will increase the contact points and contact areas between the surfaces, thereby increasing the friction force), and the resistance to pushing the lens 101 is reduced;

[0036] When the lens 101 is pulled out, the damping strip 202c-2 moves in the opposite direction relative to the above, and the second damping area 202c-2c of the damping strip 202c-2 is in frictional contact with the adapting groove 202b-1, so that the damping strip 202c-2 is stretched, and the second damping area 202c-2c is deformed and stretched, squeezing the space of the damping strip 202c-2, increasing its pressure, thereby increasing the friction force. However, if the pulling force is increased, the friction force will be broken free due to inertia, so that the lens 101 can be smoothly dragged out of the frame 100 for a certain distance. Repeated dragging can completely remove the lens 101. The damping strip 202c-2 is provided with a cavity 202c-2a through it, so that the damping strip 202c-2 can be easily deformed, squeezed and stretched;

[0037] Specifically, the mounting portion 201 includes a gasket 201a, which is provided with a mounting hole 201a-1, and is connected to the frame 100 by screws. The gasket 201a fits the frame 100, and the gasket 201a is connected to an extension piece 201b, and the extension piece 201b is connected to the elastic member 202a. The gasket 201a can be quickly installed on the frame 100 by passing the screw through the mounting hole 201a-1. The gasket 201a fits the frame 100, and the mounting portion 201 can be accurately and quickly positioned and installed.

Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete element may be changed or changed.

Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0039] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment may not be described (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention).
