The device connection base 1 is fixedly connected to the connecting member 2, the embedding body 3 is fixedly connected to the clip 4. The device connection base 1 is used to connect an external device, and the clip 4 is used to clamp an external component; the connecting member 2 has a hollow structure 21; the embedding body 3 is used to be embedded in the connecting member 2 through the hollow structure 21; the connecting member 2 is provided with strip-shaped protrusions 211 on the inner surface of the hollow structure 21, and the surface of the embedding body 3 is provided with a plurality of strip-shaped grooves 301; or the connecting member 2 is provided with a plurality of strip-shaped grooves 301 on the inner surface of the hollow structure 21, and the surface of the embedding body 3 is provided with strip-shaped protrusions 211; the strip-shaped protrusions 211 are used to engage with the strip-shaped grooves 301; by engaging the strip-shaped protrusions 211 with different strip-shaped grooves 301, the included angle between the device connection base 1 and the clip 4 is adjusted. Specifically, during installation, the strip-shaped protrusion 211 corresponds to a strip-shaped groove 301, so that the embedding body 3 is embedded in the connecting member 2 through the hollow structure 21, and then the strip-shaped protrusion 211 engages with the corresponding strip-shaped groove 301, and a certain included angle is formed between the device connection base 1 and the clip 4; when it is necessary to adjust the included angle between the device connection base 1 and the clip 4, the embedding body 3 is pulled out from the hollow structure 21 of the connecting member 2, the strip-shaped protrusion 211 is adjusted to correspond to another strip-shaped groove 301 at a corresponding angle, the embedding body 3 is re-embedded in the connecting member 2, and the strip-shaped protrusion 211 engages with the re-corresponding strip-shaped groove 301.

[0050] Optionally, the connecting member 2 is provided with a plurality of strip-shaped protrusions 211 on the inner surface of the hollow structure 21 of the member, and the surface of the embedding body 3 is provided with a plurality of strip-shaped grooves 301. The strip-shaped protrusions 211 are used to engage with the strip-shaped grooves 301; by engaging the strip-shaped protrusions 211 with different strip-shaped grooves 301, the included angle between the device connecting seat 1 and the clip 4 is adjusted. Specifically, during installation, the strip-shaped protrusions 211 correspond to the strip-shaped grooves 301, so that the embedding body 3 is embedded into the connecting member 2 through the hollow structure 21 of the member, and then the strip-shaped protrusions 211 are engaged with the corresponding strip-shaped grooves 301, and an included angle is formed between the device connecting seat 1 and the clip 4; when it is necessary to adjust the included angle between the device connecting seat 1 and the clip 4, the embedding body 3 is pulled out of the hollow structure 21 of the connecting member 2, the strip-shaped protrusions 211 are adjusted to correspond to the strip-shaped grooves 301 at other corresponding angles, the embedding body 3 is re-embedded into the connecting member 2, and the strip-shaped protrusions 211 are engaged with the newly corresponding strip-shaped grooves 301.

[0051] Optionally, the external component can be any structure with a rod-shaped or plate-shaped structure, such as a shelf with a rod-shaped or plate-shaped structure.

[0052] In some embodiments, the hollow structure 21 of the connecting member 2 is a cylindrical structure; the connecting member 2 is further provided with a gap 22; the embedding body 3 is a cylindrical structure and is used to be embedded into the cylindrical structure; when the connecting member 2 is rotated around the embedding body 3, the strip-shaped protrusions 211 deviate from the original strip-shaped grooves 301, so that the cylinder squeezes the hollow structure 21 of the member, and the hollow structure 21 expands the space through the gap 22 until the strip-shaped protrusions 211 are re-engaged with another strip-shaped groove 301, and the hollow structure 21 is restored, and so on, thereby adjusting the included angle between the device connecting seat 1 and the clip 4.

[0053] Optionally, the hollow structure 21 of the connecting member 2 is a columnar structure with a regular polygon cross-section; the embedding body 3 is a columnar structure with a regular polygon cross-section corresponding to the hollow structure 21 of the member and is used to be embedded into the hollow structure 21 of the member to form an engaging structure; by correspondingly embedding the regular polygon columnar structure of the embedding body 3 with different faces of the hollow structure 21 of the member to form an engaging structure, the included angle between the device connecting seat 1 and the clip 4 is adjusted. Specifically, during installation, the regular polygon columnar structure of the embedding body 3 is embedded into the hollow structure 21 of the member to form an engaging structure, and an included angle is formed between the device connecting seat 1 and the clip 4; when it is necessary to adjust this included angle, the embedding body 3 is pulled out of the hollow structure 21 of the connecting member 2, and the regular polygon columnar structure of the embedding body 3 is adjusted to be correspondingly embedded with different faces of the hollow structure 21 of the member again to form an engaging structure, and the angle adjustment can be completed.

[0054] Optionally, the hollow structure 21 of the connecting member 2 is a regular polygonal columnar structure in cross-section; the connecting member 2 is further provided with a gap 22; the embedding body 3 is a regular polygonal columnar structure in cross-section corresponding to the hollow structure 21, and is used to be embedded into the hollow structure 21 to form a clamping structure; by correspondingly embedding the regular polygonal columnar structure of the embedding body 3 with different faces of the hollow structure 21 to form a clamping structure, the included angle between the device connecting seat 1 and the clip 4 is adjusted. Specifically, when the connecting member 2 is rotated around the regular polygonal columnar structure of the embedding body 3, the clamping surface between the connecting member 2 and the embedding body 3 is offset, so that the hollow structure 21 expands the space through the gap 22 until the regular polygonal columnar structure of the hollow structure 21 is re-clamped with another face of the regular polygonal columnar structure of the embedding body 3, and the hollow structure 21 is restored to become smaller again because the gap 22 is restored to become smaller, and so on, thereby adjusting the included angle between the device connecting seat 1 and the clip 4.

[0055] Optionally, the regular polygonal columnar structure can be an equilateral triangle, a square, a regular pentagon, and so on, and so on.

[0056] In some embodiments, the embedding body 3 is further provided with a limiting block 302, which is used to limit the connecting member 2 from detaching from the embedding body 3 after the embedding body 3 is embedded into the hollow structure 21 of the connecting member 2.

[0057] In some embodiments, the gap 22 is arranged along the axis of the cylindrical structure of the connecting member 2, the limiting block 302 is fixedly connected to the embedding body 3, and is located at a position far from the connection point between the embedding body 3 and the clip 4; when the cylindrical structure of the embedding body 3 is embedded into the hollow structure 21 and the strip-shaped protrusion 211 is engaged with the strip-shaped groove 301, the limiting block 302 passes through the gap 22 of the connecting member 2; when the connecting member 2 is rotated around the embedding body 3, the limiting block 302 is deviated from the gap 22, so as to limit the connecting member 2 from detaching from the embedding body 3.

[0058] Optionally, the limiting block 302 is detachably connected to the embedding body 3 and is located at a position far from the connection point between the embedding body 3 and the clip 4; during installation, the strip-shaped protrusion 211 corresponds to the strip-shaped groove 301, and then the cylindrical structure of the embedding body 3 is embedded into the hollow structure 21. At this time, the strip-shaped protrusion 211 and the strip-shaped groove 301 are engaged with each other. After the cylindrical structure of the embedding body 3 is completely embedded into the hollow structure 21, a part of the structure will be exposed. This part of the structure is located at a position far from the connection point between the embedding body 3 and the clip 4. Then, the limiting block 302 is installed on this part of the structure, and the limiting block 302 is used to limit the connecting member 2 from detaching from the embedding body 3.

[0059] Preferably, the strip-shaped protrusion 211 is arc-shaped, and the strip-shaped groove 301 is also arc-shaped corresponding to the strip-shaped protrusion 211. Such a setting makes the strip-shaped protrusion 211 and the strip-shaped groove 301 have a certain firmness when engaged, and does not affect the rotation of the connecting member 2 around the cylindrical structure of the embedding body 3.

[0060] In some embodiments, a connecting arm 5 is further included. One end of the embedding body 3 is fixedly connected to one end of the connecting arm 5, and the other end of the connecting arm 5 is fixedly connected to the clip 4. The connecting arm 5 extends the distance between the clip 4 and the embedding body 3, making the embedding body 3 and the clip 4 relatively independent in space and having less interference. When the embedding body 3 is inserted into or withdrawn from the hollow structure 21 of the connecting member 2, due to the larger space, the operation is more convenient.

[0061] Preferably, a connecting arm 5 is further included. One end of the embedding body 3 is fixedly connected to one end of the connecting arm 5, and the other end of the connecting arm 5 is fixedly connected to the upper part of the clip 4. The lower part of the clip 4 is used to clamp an external component. The connecting arm 5 extends the distance between the clip 4 and the embedding body 3, making the embedding body 3 and the clip 4 relatively independent in space. When the embedding body 3 is inserted into or withdrawn from the hollow structure 21 of the connecting member 2, due to the larger space, the operation is more convenient.

[0062] In some embodiments, the clip 4 includes a bottom plate 41 and an elastic piece 42. The bottom plate 41 is fixedly connected to the elastic piece 42, and the elastic piece 42 is fixedly connected to the embedding body 3. The bottom plate 41 and the elastic piece 42 together form a structure with an internal space and an elastically openable mouth for clamping an external component.

[0063] In some embodiments, the bottom plate 41 includes a plate head portion 411 and a plate foot portion 412. One side of the plate head portion 411 and one side of the plate foot portion 412 are integrally formed. The other side of the plate head portion 411 is integrally formed with one side of the elastic piece 42. The other side of the elastic piece 42 extends away from the plate head portion 411 to form a piece head portion 421, then continues to extend towards the plate foot portion 412 to form a piece body portion 422, and when it continues to extend to the plate foot portion 412, it becomes a piece foot portion 423. The plate head portion 411, the plate foot portion 412, the piece head portion 421, the piece body portion 422, and the piece foot portion 423 together form a structure with an internal space and an elastic opening between the piece foot portion 423 and the plate foot portion 412 for clamping an external component. The piece head portion 421 is fixedly connected to the embedding body 3.

[0064] In some embodiments, the plate foot portion 412 extends away from the plate head portion 411 to form a plate tail portion 413, and the sheet foot portion 423 continues to extend and warp away from the plate tail portion 413 to form a sheet tail portion 424; the plate tail portion 413 and the sheet tail portion 424 together form a large opening for conveniently spreading the elastic opening and clamping an external component.

[0065] In some embodiments, the plate foot portion 412 has a plate tooth-like structure 4121 at the elastic opening and / or the sheet foot portion 423 has a sheet tooth-like structure 4231 at the elastic opening, and the plate tooth-like structure 4121 and / or the sheet tooth-like structure 4231 are used to more firmly clamp the external component.

[0066] Preferably, the front surface of the device connection base 1 is a seat groove 11, and the seat groove 11 is used to connect an external device; the back surface of the device connection base 1 is fixedly connected to the connecting member 2. Preferably, the upper part of the back surface of the device connection base 1 is fixedly connected to the connecting member 2.

[0067] Preferably, the seat groove 11 is a C-shaped structure, that is, there are two corresponding side walls and the other two side walls are not provided. Such a setting is such that the size of the connected external device is not overly restricted, and as long as it can be connected by the two corresponding side walls of the seat groove 11, it can be a snap connection or a sliding connection.

[0068] Preferably, one side wall of the seat groove 11 is provided with a through hole, defined as a groove through hole 111, and the other side of the seat groove 11 is provided with a groove baffle 112. Such a setting is used to more firmly snap together when facing an external device with a matching structure.

[0069] In some embodiments, an information display screen 6 is provided, which is applied to the device connection structure described in any one of the above embodiments, and the back of the information display screen 6 is connected to the device connection base 1.

[0070] Preferably, the information display screen 6 includes a display screen body 61 and a screen base 62. The back of the display screen body 61 is fixedly connected to one side of the screen base 62, and the screen base 62 is used to be snap-connected within the seat groove 11.

[0071] Preferably, two sides of the screen base 62 are respectively provided with a base first protrusion 621 and a base second protrusion 622. During installation, the base second protrusion 622 is snap-connected to the groove baffle 112 of the seat groove 11, and the base first protrusion 621 is snap-connected to the groove through hole 111 of the seat groove 11, thereby snap-connecting the screen base 62 within the seat groove 11.

[0072] Since the remaining two side walls are not provided in the seat groove 11, after the screen base 62 is snap-fitted to the mutually corresponding two side walls of the seat groove 11, there is a possibility that the screen base 62 moves towards the openings of the remaining two side walls that are not provided, so it is not firm enough. Based on this background, preferably, a bracket-shaped protrusion is provided inside the seat groove 11, namely a left bracket protrusion 113 and a right bracket protrusion 114 respectively. The two bracket protrusions together enclose a structure of an inner groove within a groove; combined with the fact that a third protrusion of the base is provided on the surface of the screen base 62 facing the seat groove 11 for snap-fitting with the structure of the inner groove within a groove; when the screen base 62 is snap-fitted into the seat groove 11 through the groove through-hole 111 and the groove baffle 112, the structure of the inner groove within a groove further restricts the movement of the screen base 62 towards the remaining two side walls that are not provided by snap-fitting with the third protrusion of the base; the above settings make the screen base 62 more firmly snap-fitted into the seat groove 11.

[0073] Optionally, when the external component is a sheet-like structure and the angle does not need to be adjusted, using the clip 4 to hold the external component is rather inefficient and not firm, so a simple and convenient structure is needed. Based on this, two grooves are further provided on the back surface of the device connection base 1, namely a back first groove 115 and a back second groove 116, which are symmetrically arranged on both sides of the back surface of the device connection base 1. The openings of the back first groove 115 and the back second groove 116 face each other. One end of both is closed and the other end of both is open, which makes the two enclose a large back chute; moreover, at the exit of the large back chute on the back surface of the device connection base 1, an elastic limit protrusion 117 is further provided; with the structural arrangement of the large back chute combined with the elastic limit protrusion 117, when in use, only need to insert the external component of the sheet-like structure into the large back chute. During this process, the elastic limit protrusion 117 is slightly squeezed. When one end of the sheet-like structure is inserted to the bottom of the large back chute, the other end of the sheet-like structure also completely enters and no longer squeezes the elastic limit protrusion 117, and the elastic limit protrusion 117 resumes its original state and restricts the sheet-like structure to prevent it from detaching, forming a snap-fit; the above settings make it more convenient and efficient when connecting the external component of the sheet-like structure.

[0074] Specifically, compared with the upper part of the back surface of the device connection base 1 being fixedly connected to the connecting member 2, the two grooves are arranged at the positions below the back surface of the device connection base 1 and the connecting member 2, making the arrangement more reasonable.

[0075] It should be noted that although the above-mentioned embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby.
