Description

Technical Field

[0001] This utility model relates to the field of brackets, and in particular to a connection structure and bracket. Background Technology

[0002] In today's society, electronic devices have permeated every aspect of people's lives. To facilitate the use of electronic devices, people often use stands to support mobile phones and other electronic devices. To further enhance the user experience and meet the needs of different scenarios, stands are usually connected to quick-change connection structures. These connection structures link the stands and electronic devices, providing both secure fixation and convenient, quick access to the devices.

[0003] In existing technologies, quick-change connection structures often use a rotary snap-fit ​​method for connection, which has problems such as low reliability and abnormal noise. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a connection structure that is highly reliable and less prone to generating abnormal noise.

[0005] This utility model also proposes a bracket including the above-mentioned connection structure.

[0006] The connection structure according to the first aspect of the present invention includes:

[0007] Base;

[0008] The connecting part has one end abutting against the base and is provided with a connecting hole. The side wall of the connecting hole is provided with a connecting slope. Along the direction away from the base, the distance from the connecting slope to the center line of the connecting part increases.

[0009] The snap-fit ​​part is slidably disposed on the base. During the sliding process, the snap-fit ​​part can extend into the connection hole and abut against the connection slope, and can also exit the connection hole along the connection slope.

[0010] An adjustment component is movably disposed on the base and abuts against the locking part. During the movement of the adjustment component relative to the base, it can apply a force to the locking part away from the connecting part along the extension direction of the center line of the connecting part, so as to drive the locking part to exit the connecting hole along the connecting slope.

[0011] The connection structure according to the embodiment of this utility model has at least the following beneficial effects:

[0012] In this embodiment, the connection structure features a connecting ramp on the connecting part, inclined relative to its centerline. A locking part is slidably mounted on the base, and an adjustment component movable relative to the base is provided. During sliding, the locking part abuts against the connecting ramp to lock the connecting part relative to the base. By adjusting the adjustment component to move relative to the base, a force can be applied to the locking part along the extension direction of the centerline of the connecting part away from the connecting part, causing the locking part to exit the connecting hole along the connecting ramp, thereby unlocking the connecting part. The locking part can move from the unlocked position to the locked position by adjusting the adjustment component or by providing a separate reset structure. This embodiment uses the locking part abutting against the connecting ramp to lock the connecting part, which reduces the connection gap between the connecting part and the base, ensuring a reliable connection and reducing the likelihood of abnormal noise. Furthermore, when the locking part unlocks the connecting part, it needs to move along the connecting ramp to exit the connecting hole, requiring not only a force perpendicular to the centerline of the connecting part but also a force parallel to the centerline of the connecting part, making the connection structure less prone to loosening during use and ensuring high reliability.

[0013] According to some embodiments of the present invention, the adjustment component includes:

[0014] The transmission part abuts against the locking part and is capable of moving relative to the base along the extension direction of the center line of the connecting part. When the transmission part moves away from the connecting part along the extension direction of the center line of the connecting part, it can apply a force to the locking part away from the connecting part along the extension direction of the center line of the connecting part.

[0015] According to some embodiments of the present invention, the transmission part is rotatably disposed on the base, and the rotation axis of the transmission part is parallel to the center line of the connecting part. A guide structure is provided between the base and the transmission part. When the transmission part rotates in a set direction, the guide structure can guide the transmission part to move away from the connecting part along the extension direction of the center line of the connecting part.

[0016] According to some embodiments of the present invention, the guiding structure includes a first guiding surface disposed on one of the transmission part and the base. The first guiding surface extends obliquely along the extension direction of the rotation axis of the transmission part. The other of the transmission part and the base abuts against the first guiding surface so as to guide the transmission part to move away from the connecting part along the extension direction of the center line of the connecting part when the transmission part rotates in the set direction.

[0017] According to some embodiments of the present invention, the guide structure further includes a second guide surface disposed on the other of the transmission part and the base, wherein both the second guide surface and the first guide surface are helical surfaces, and the second guide surface is attached to the first guide surface.

[0018] According to some embodiments of the present invention, the adjustment component further includes:

[0019] An adjustment part is rotatably mounted on the base, and the rotation axis of the adjustment part is parallel to the center line of the connecting part;

[0020] In this configuration, one of the adjusting part and the driving part is provided with a driving column, and the other is provided with a driving hole. The driving column extends along the extension direction of the center line of the connecting part and slides through the driving hole, so that the adjusting part can rotate synchronously with the driving part.

[0021] According to some embodiments of the present invention, the connection structure further includes:

[0022] An elastic reset part is disposed between the base and the snap-fit ​​part, and is used to apply an elastic force to the snap-fit ​​part in the direction of extension of the center line of the connection part toward the connection part.

[0023] According to some embodiments of the present invention, the base defines a mounting cavity, and a through guide groove is provided on the side of the mounting cavity near the connecting part. The extending direction of the guide groove forms an angle with the center line of the connecting part. The snap-fit ​​part includes:

[0024] The main body is located within the mounting cavity and abuts against the adjustment assembly;

[0025] A locking block is connected to the main body and slides through the guide groove. The locking block is used to abut against the connecting inclined surface.

[0026] According to some embodiments of the present invention, one of the base and the connecting part is provided with a positioning boss, and the other is provided with a positioning groove. The positioning boss is inserted into the positioning groove to restrict the rotation of the connecting part relative to the base.

[0027] The bracket according to a second aspect embodiment of the present invention includes the connection structure described in the first aspect embodiment.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0045] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0046] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0048] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0049] Connection structures are commonly used to connect parts, allowing one part to be connected to or separated from another, thus achieving the purpose of quickly connecting or separating two parts. For example, connection structures can be used to fix a mobile phone to a desktop, car cockpit, bicycle handlebars, etc.

[0050] Reference Figures 1 to 3 As shown, this utility model proposes a connection structure, including: a base 100, a connecting part 200, a snap-fit ​​part 300, and an adjustment component 400.

[0051] One end of the connecting part 200 abuts against the base 100, and a connecting hole 201 is provided at the end of the connecting part 200 abutting against the base 100. A connecting inclined surface 202 is provided on the side wall of the connecting hole 201. Along the direction away from the base 100, the distance from the connecting inclined surface 202 to the center line of the connecting part 200 increases, that is, the connecting inclined surface 202 is inclined relative to the center line of the connecting part 200. It should be noted that the state in which one end of the connecting part 200 abuts against the base 100 refers to the state when the connecting structure is in use. When the connecting structure is not needed, the connecting part 200 can be separated from the base 100.

[0052] The latching part 300 is slidably disposed on the base 100. The sliding direction of the latching part 300 forms an angle with the center line of the connecting part 200. During the sliding process, the latching part 300 can extend into the connecting hole 201 and abut against the connecting inclined surface 202, and can also exit the connecting hole 201 along the connecting inclined surface 202. When the latching part 300 extends into the connecting hole 201 and abuts against the connecting inclined surface 202, it is in the locked position, which can lock the connecting part 200 relative to the base 100. When the latching part 300 exits the connecting hole 201 along the connecting inclined surface 202, it is in the unlocked position, which can release the locking of the connecting part 200, so that the connecting part 200 can be separated from the base 100.

[0053] The adjustment component 400 is movably disposed on the base 100 and abuts against the locking part 300. During the movement of the adjustment component 400 relative to the base 100, it can apply a force to the locking part 300 in the direction extending away from the connecting part 200 along the center line of the connecting part 200, so as to drive the locking part 300 to exit the connecting hole 201 along the connecting slope 202, thereby unlocking the connecting part 200 relative to the base 100.

[0054] It is understandable that, since the distance from the connecting slope 202 to the center line of the connecting part 200 increases in the direction away from the base 100, that is, the connecting slope 202 is inclined relative to the center line of the connecting part 200, it is only necessary to make the sliding direction of the locking part 300 relative to the base 100 form a certain angle with the center line of the connecting part 200, so that the adjusting component 400 can apply a force to the locking part 300 away from the connecting part 200 in the extension direction of the center line of the connecting part 200, thereby driving the locking part 300 to exit the connecting hole 201 along the connecting slope 202.

[0055] In this embodiment, the connection structure includes a connecting ramp 202 inclined relative to the centerline of the connecting portion 200, a locking portion 300 slidably disposed on the base 100, and an adjustment component 400 movable relative to the base 100. During sliding, the locking portion 300 abuts against the connecting ramp 202 to lock the connecting portion 200 relative to the base 100. By adjusting the adjustment component 400 to move relative to the base 100, a force can be applied to the locking portion 300 along the extension direction of the centerline of the connecting portion 200 away from the connecting portion 200, thereby causing the locking portion 300 to exit the connecting hole 201 along the connecting ramp 202, thus unlocking the connecting portion 200. The movement of part 300 from the unlocked position to the locked position can be achieved by adjusting the adjustment component 400 or by setting a separate reset structure. In this embodiment, the locking of the connecting part 200 is achieved by using the snap-fit ​​part 300 to abut against the connecting slope 202, which can reduce the connection gap between the connecting part 200 and the base 100, making the connection reliable and less prone to abnormal noise. In addition, when the snap-fit ​​part 300 unlocks the connecting part 200, it needs to move along the connecting slope 202 to the exit connecting hole 201. This requires not only a force perpendicular to the center line of the connecting part 200, but also a force parallel to the center line of the connecting part 200, making the connection structure less prone to loosening during use and ensuring high reliability.

[0056] It is conceivable that the base 100 can be used to provide mounting support for the connecting part 200, the snap-fit ​​part 300, the adjustment component 400, etc., and can also be used to connect other components, such as brackets fixed to a desktop or bicycle handlebars. A threaded hole can be provided on the side of the base 100 away from the connecting part 200 to connect other components. The connecting part 200 can be used to connect devices such as mobile phones and tablets. For example, adhesive can be applied to the side of the connecting part 200 away from the base 100 to connect mobile phones or tablets.

[0057] It is conceivable that the number of snap-fit ​​parts 300 can be three, four or more, and only one connecting hole 201 can be provided, with the center line of the connecting hole 201 being collinear with the center line of the connecting part 200. The connecting slope 202 can be a curved surface or a plane. Multiple connecting holes 201 can also be provided, corresponding one-to-one with the snap-fit ​​parts 300.

[0058] It is conceivable that the adjustment assembly 400 may consist of only one component abutting against the latching portion 300, or it may consist of multiple components, at least one of which abuts against the latching portion 300. The adjustment assembly 400 may be mounted on the base 100 by means of sliding, rotating, or other means that can drive the latching portion 300 to move.

[0059] In some embodiments of this utility model, reference is made to Figures 1 to 4As shown, the adjustment assembly 400 includes a transmission part 410, which is movably disposed on the base 100 and abuts against the locking part 300. The transmission part 410 can move relative to the base 100 along the extension direction of the center line of the connecting part 200. When the transmission part 410 moves away from the connecting part 200 along the extension direction of the center line of the connecting part 200, it can apply a force to the locking part 300 along the extension direction of the center line of the connecting part 200 away from the connecting part 200, thereby driving the locking part 300 to exit the connecting hole 201 along the connecting slope 202.

[0060] Based on the above embodiments, it is understood that when the transmission part 410 applies force to the locking part 300, the direction of the force applied by the transmission part 410 and the direction of movement of the transmission part 410 are consistent with the extension direction of the center line of the connecting part 200. Therefore, the transmission part 410 and the locking part 300 can be abutted in a planar fit manner to increase the contact area and make the locking part 300 move more smoothly.

[0061] For example, refer to Figure 2 , Figure 5 and Figure 9 As shown, a first transmission surface 413 can be provided on the transmission part 410, and a second transmission surface 303 can be provided on the locking part 300, such that both the first transmission surface 413 and the second transmission surface 303 are perpendicular to the center line of the connecting part 200. The second transmission surface 303 is located on the side of the first transmission surface 413 away from the connecting part 200. The second transmission surface 303 is used to fit against the first transmission surface 413, so that when the transmission part 410 moves away from the connecting part 200 along the extension direction of the center line of the connecting part 200, a force can be applied to the locking part 300 along the extension direction of the center line of the connecting part 200 away from the connecting part 200.

[0062] Based on the above embodiments, it is conceivable that the movement of the latching part 300 from the unlocked position to the locked position can be achieved by adjusting the transmission part 410 or by setting a reset structure.

[0063] For example, the transmission part 410 drives the locking part 300 from the unlocked position to the locked position. Under the premise that the transmission part 410 is provided with a first transmission surface 413 and the locking part 300 is provided with a second transmission surface 303, a third transmission surface (not shown) can be provided on the transmission part 410 and a fourth transmission surface (not shown) can be provided on the locking part 300. The third and fourth transmission surfaces are both perpendicular to the center line of the connecting part 200, and the third transmission surface is located on the side of the fourth transmission surface away from the connecting part 200. The third transmission surface is used to fit against the fourth transmission surface. Thus, when the transmission part 410 moves toward the connecting part 200 along the extension direction of the center line of the connecting part 200, a force can be applied to the locking part 300 along the extension direction of the center line of the connecting part 200 toward the connecting part 200.

[0064] Obviously, the first transmission surface 413 and the third transmission surface can be formed by providing grooves on the transmission part 410, and the second transmission surface 303 and the fourth transmission surface can be formed by providing block-shaped or plate-shaped structures on the snap-fit ​​part 300.

[0065] For example, by setting up a separate reset structure to move the locking part 300 from the unlocked position to the locked position, such as... Figure 1 and Figure 2 As shown, an elastic reset part 500 can be provided between the base 100 and the snap-fit ​​part 300. The elastic reset part 500 is used to apply an elastic force to the snap-fit ​​part 300 in the direction of extending along the center line of the connecting part 200 toward the connecting part 200.

[0066] In some embodiments of this utility model, the transmission part 410 may be slidably disposed on the base 100 along the extension direction of the center line of the connecting part 200. For example, the transmission part 410 can be slidably installed by providing a guide rail assembly between the base 100 and the transmission part 410. In this case, it is only necessary to apply force to the transmission part 410 along the extension direction of the center line of the connecting part 200, so that the transmission part 410 can drive the locking part 300 to move and realize the reset of the transmission part 410.

[0067] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, the transmission part 410 can also be rotatably mounted on the base 100, and the rotation axis of the transmission part 410 is parallel to the center line of the connecting part 200. That is, the transmission part 410 can not only move linearly along the extension direction of the center line of the connecting part 200, but also rotate around an axis parallel to the center line of the connecting part 200. A guide structure is provided between the base 100 and the transmission part 410. When the transmission part 410 rotates in a set direction, the guide structure can guide the transmission part 410 to move away from the connecting part 200 along the extension direction of the center line of the connecting part 200. This set direction can be clockwise or counterclockwise.

[0068] Based on the above settings, the user can control the transmission part 410 to rotate in a set direction so that the transmission part 410 moves away from the connecting part 200 along the extension direction of the center line of the connecting part 200, thereby driving the locking part 300 to exit the connecting hole 201 along the connecting slope 202. This is more convenient than pushing and pulling the transmission part 410 along the extension direction of the center line of the connecting part 200.

[0069] It is obvious that when the transmission part 410 moves close to the connecting part 200 along the extension direction of the center line of the connecting part 200, the guide structure can guide the transmission part 410 to rotate in a direction opposite to the above-mentioned set direction.

[0070] In some specific embodiments, such as Figure 2 As shown, a first mounting shaft 104 is provided on the base 100. The axis of the first mounting shaft 104 is parallel to the center line of the connecting part 200. A circular hole is provided on the transmission part 410 to be fitted onto the first mounting shaft 104, so that the transmission part 410 can move along the axial direction of the first mounting shaft 104 and can also rotate around the axis of the first mounting shaft 104.

[0071] Furthermore, refer to Figure 3 , Figures 5 to 7 As shown, the guiding structure includes a first guiding surface 101 disposed on the base 100. The first guiding surface 101 extends obliquely along the extension direction of the rotation axis of the transmission part 410. The transmission part 410 abuts against the first guiding surface 101 so that when the transmission part 410 rotates in a set direction, it is guided to move away from the connecting part 200 along the extension direction of the center line of the connecting part 200. Since the first guiding surface 101 extends obliquely along the extension direction of the rotation axis of the transmission part 410, and the transmission part 410 abuts against the first guiding surface 101, when the transmission part 410 rotates and the first guiding surface 101 is subjected to force, the reaction force on the transmission part 410 will generate a component force along the extension direction of the rotation axis of the transmission part 410, so that the transmission part 410 can move away from the connecting part 200 along the extension direction of the rotation axis of the transmission part 410. Obviously, the first guiding surface 101 can be an oblique plane or a helical surface.

[0072] In this context, the distance between the first guide surface 101 and the connecting portion 200 increases along the aforementioned predetermined direction. Conversely, taking the first transmission surface 413 in the above embodiment as a reference, the distance between the first guide surface 101 and the first transmission surface 413 decreases along the aforementioned predetermined direction.

[0073] Furthermore, refer to Figure 3 , Figures 5 to 7 As shown, the guiding structure also includes a second guiding surface 411 disposed on the transmission part 410. The second guiding surface 411 is adapted to the first guiding surface 101. Both the second guiding surface 411 and the first guiding surface 101 are spiral surfaces, and the second guiding surface 411 is attached to the first guiding surface 101. By setting two adapted and attached spiral guiding surfaces, the force between the transmission part 410 and the base 100 is transmitted. The contact area is large, and the transmission is smooth and stable.

[0074] It is conceivable that multiple sets of guiding structures can be set.

[0075] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 8As shown, the adjustment assembly 400 also includes an adjustment part 420, which is rotatably disposed on the base 100. The rotation axis of the adjustment part 420 is parallel to the center line of the connecting part 200. The transmission part 410 is provided with a transmission column 412, and the adjustment part 420 is provided with a transmission hole 421. The transmission column 412 extends along the extension direction of the center line of the connecting part 200 and slides through the transmission hole 421, so that the adjustment part 420 can rotate synchronously with the transmission part 410.

[0076] Based on the above configuration, the user only needs to rotate the adjusting part 420 to drive the transmission part 410 to rotate. Since the adjusting part 420 only moves in one direction, the operation is simpler. Furthermore, it is understandable that to ensure the locking effect of the locking part 300, multiple locking parts 300 are usually provided. That is, the transmission part 410 needs to abut against multiple locking parts 300. In the layout, multiple locking parts 300 are also placed around the transmission part 410. In this case, directly rotating the transmission part 410 is easily obstructed by the locking parts 300. However, by using the adjusting part 420 to drive the transmission part 410 to rotate, the adjusting part 420 only needs to be positioned so as not to interfere with the locking parts 300 during rotation. Since the adjusting part 420 does not need to abut against the locking parts 300, the layout is convenient.

[0077] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, the connection structure also includes an elastic reset part 500, which is disposed between the base 100 and the locking part 300. The elastic reset part 500 applies an elastic force to the locking part 300 along the extension direction of the center line of the connecting part 200 towards the connecting part 200, allowing the locking part 300 to extend into the connecting hole 201 and abut against the connecting inclined surface 202. By providing the elastic reset part 500, the locking part 300 can automatically reset from the unlocked position to the locked position. The user only needs to operate the adjustment part 420 when releasing the locking of the connecting part 200, making operation more convenient and faster. Furthermore, the elastic force applied by the elastic reset part 500 to the locking part 300 is opposite in direction to the force applied by the adjustment component 400 to the locking part 300; that is, the driving force and the reset force are opposite, thus making the force on the locking part 300 more balanced.

[0078] It is conceivable that the elastic reset part 500 can be a tension spring, a compression spring, or other elastic structure that meets the requirements.

[0079] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2As shown, the base 100 includes a body 105 and a cover 106. The body 105 has a recessed cavity. The cover 106 is disposed near the connecting part 200 and connected to the body 105. The body 105 and the cover 106 enclose each other to form a mounting cavity. The mounting cavity can be used to install components such as the snap-fit ​​part 300, the adjustment part 420, the transmission part 410, and the elastic reset part 500, so as to improve the aesthetics of the connection structure and also provide a certain degree of protection for each component.

[0080] For example, the mounting cavity can be used to mount the snap-fit ​​portion 300. In some embodiments of this invention, reference is made to... Figure 1 and Figure 2 As shown, a through guide groove 102 is provided on the cover 106. The guide groove 102 communicates with the mounting cavity. The extension direction of the guide groove 102 forms an angle with the center line of the connecting part 200, that is, the guide groove 102 is inclined relative to the extension direction of the center line of the connecting part 200. In addition, along the extension direction of the guide groove 102, the projection of the guide groove 102 at least partially coincides with the connecting inclined surface 202. The locking part 300 includes a main body 301 and a locking block 302. The main body 301 is disposed in the mounting cavity and abuts against the transmission part 410. The second transmission surface 303 is formed on the main body 301. The locking block 302 is connected to the main body 301 and slides through the guide groove 102, thereby sliding the locking part 300 onto the base 100. When the locking block 302 slides along the guide groove 102, it can extend into the connecting hole 201 and abut against the connecting inclined surface 202 to lock the connecting part 200.

[0081] It is conceivable that there can be multiple guide grooves 102, each corresponding to a snap-fit ​​part 300.

[0082] For example, the transmission part 410 can also be installed simultaneously with the mounting cavity mounting snap-fit ​​part 300. In some embodiments of this utility model, refer to... Figure 2 As shown, a first mounting shaft 104 is provided at the inner end of the cover 106. The axis of the first mounting shaft 104 is parallel to the center line of the connecting part 200. A circular hole is provided on the transmission part 410 to be fitted onto the first mounting shaft 104, so that the transmission part 410 can move along the axial direction of the first mounting shaft 104 and can also rotate around the axis of the first mounting shaft 104.

[0083] For example, while mounting the snap-fit ​​part 300 and the transmission part 410 inside the mounting cavity, the adjustment part 420 can also be installed. In some embodiments of this utility model, refer to... Figure 2 , Figure 4 and Figure 8As shown, a second mounting shaft 107 is provided at the inner end of the main body 105, and a limiting groove 108 extending circumferentially along the second mounting shaft 107 is provided on the periphery of the main body 105. The two opposite ends of the limiting groove 108 along the circumferential direction of the second mounting shaft 107 are closed ends. The adjustment part 420 includes a turntable 422 and an operating handle 423. The turntable 422 has a circular hole for rotatably mounting on the second mounting shaft 107. A transmission hole 421 is provided on the turntable 422. The operating handle 423 is connected to the turntable 422 and extends through the limiting groove 108 to the outside of the base 100.

[0084] Obviously, since the two ends of the limiting groove 108 along the second mounting shaft 107 are closed, the movement of the operating handle 423 can be restricted, thereby limiting the rotation angle of the adjustment part 420. The operating handle 423 passes through the limiting groove 108 and extends to the outside of the base 100, which makes it convenient for the user to rotate the adjustment part 420, making the operation convenient.

[0085] For example, when the snap-fit ​​part 300, the transmission part 410, and the adjustment part 420 are all installed in the mounting cavity, the elastic reset part 500 can also be installed in the mounting cavity. In some embodiments of this utility model, refer to... Figure 1 As shown, the elastic reset part 500 adopts a compression spring; the inner end of the cover 106 is provided with a mounting post 109, the mounting post 109 extends along the extension direction of the center line of the connecting part 200, the compression spring is sleeved on the mounting post 109, and the two ends of the compression spring abut against the body 105 and the main body 301 respectively, so as to apply an elastic force to the main body 301 in the extension direction of the center line of the connecting part 200 toward the connecting part 200.

[0086] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, one of the base 100 and the connecting part 200 is provided with a positioning boss 103, and the other is provided with a positioning groove 203. The positioning boss 103 is inserted into the positioning groove 203 to restrict the rotation of the connecting part 200 relative to the base 100. In some specific embodiments, multiple connecting holes 201 are provided, and each corresponds to a snap-fit ​​part 300. The multiple connecting holes 201 are distributed circumferentially around the center line of the connecting part 200. A positioning groove 203 is provided at the center of the connecting part 200, extending along the extension direction of its center line. The positioning groove 203 is a rectangular groove. The positioning boss 103 is adapted to be inserted into the positioning groove 203 to restrict the rotation of the connecting part 200 relative to the base 100, and at the same time restrict the displacement of the connecting part 200 relative to the base 100 in a direction perpendicular to its center line.

[0087] In addition, it is conceivable that, in order to further improve the reliability of the connection structure, magnets can be provided on the base 100 and the connecting part 200 respectively.

[0088] The following describes the usage method of the connection structure of one embodiment of the present invention. In use, the adjustment part 420 is rotated in a set direction. During the rotation of the adjustment part 420, the transmission part 410 is driven to rotate synchronously through the cooperation of the transmission hole 421 and the transmission column 412. At the same time as the transmission part 410 rotates, the guide structure guides the transmission part 410 to move away from the connection part 200 along the extension direction of the center line of the connection part 200, thereby pushing the locking part 300 to slide into the base 100 in the guide groove 102, so that the locking part 300 moves to the unlocked position. At this time, the elastic reset part 500 (compression spring) is compressed, and then the connection part 200 is pressed against the base 100, so that the positioning boss 103 is inserted into the positioning groove 203. Finally, the external force is removed. As the external force disappears, the elastic reset part 500 is reset, driving the locking part 300 to extend into the connection hole 201 and abut against the connection inclined surface 202, thereby locking the connection part 200.

[0089] The present invention also proposes a bracket, which includes the connection structure of the first aspect embodiment described above. A threaded hole can be provided on the side of the base 100 away from the connecting part 200 for connecting other components, and adhesive can be applied to the side of the connecting part 200 away from the base 100 for connecting devices such as mobile phones or tablets.
