[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] The core of the present invention is to provide a quick-release rotary buckle structure. By providing a hook-shaped buckle and a through buckle slot hole, the locking and separation of the two can be achieved by rotation. Moreover, a spring piece is provided between the assembly body and the installation body. When the buckle and the buckle slot hole between the two are separated, the spring piece can directly separate the two to achieve quick release.

[0037] Another core of the present invention is to provide a display screen bracket including the above-mentioned quick-release rotary buckle structure, which has the same technical features and can achieve the same purpose.

[0038] Please refer to Figures 1-7 , a quick-release rotary buckle structure, including:

[0039] The installation body 2 is provided with a plurality of groups of buckle slot holes 301 on the surface in a circular array. The buckle slot holes 301 are in a strip-shaped structure.

[0040] The assembly body 1 is provided with a plurality of groups of hook-shaped buckles 104 vertically on the surface, which are used to penetrate the buckle slot holes 301 and are combined and limited with the buckle slot holes 301 after the relative rotation of the assembly body 1 and the installation body 2. The positions of the buckles 104 and the buckle slot holes 301 correspond one by one.

[0041] The spring piece 4 is arranged between the installation body 2 and the assembly body 1 and is used to push the installation body 2 and the assembly body 1 away from each other.

[0042] Taking the installation of the decorative cover on the rear shell of the display screen bracket as an example, the installation body 2 is the rear shell of the display screen, and the assembly body 1 is the decorative cover. As Figure 1 shown, the buckles 104 are vertically arranged on the inner surface of the decorative cover. The end of the buckle 104 can be inserted into the buckle slot hole 301 of the rear cover. After insertion, rotate the decorative cover, and the hook body of the buckle 104 directly abuts against the inner wall of the rear shell, thereby restricting the buckle 104 from detaching from the buckle slot hole 301, that is, the installation of the decorative cover and the rear shell is completed.

[0043] When disassembly is required, rotate the decorative cover in the reverse direction, and the hook body of the buckle 104 is separated from the inner wall of the rear shell, that is, it no longer restricts the buckle 104 from detaching from the buckle slot hole 301, that is, the separation of the rear shell and the decorative cover is completed.

[0044] A spring sheet 4 is fixedly arranged on the rear shell. When the decorative cover is installed, the decorative cover compresses the spring sheet 4 to deform and store energy. When the buckle 104 is disengaged from the buckle slot 301, the elastic potential energy in the spring sheet 4 pushes the decorative cover to be separated from the rear shell, thereby facilitating the separation of the decorative cover from the rear shell surface.

[0045] Moreover, if Figure 4 As shown, an operation indicator mark 101 and an alignment mark 102 in the form of an arrow are provided on the outer surface of the decorative cover, that is, the assembly 1, wherein the operation indicator mark 101 is used to indicate the rotation direction required for the decorative cover and the rear housing to be installed and the rotation direction required for the separation, and the alignment mark 102 is used to indicate the position of the buckle 104 when it passes through the buckle slot 301;

[0046] When assembling the decorative cover, one only needs to align the alignment mark 102 on the decorative cover with the specific mark on the rear shell and press down to allow the buckle 104 to pass through the buckle slot 301, and then rotate the locking direction on the installation operation indicator mark 101 to complete the installation of the decorative cover.

[0047] In some embodiments, one end of the spring sheet 4 is fixed to the mounting body 2 by a screw 401, and the other end is tilted upward, and the end is provided with an arc-shaped downward bend; when the buckle 104 is engaged in the buckle slot 301, the arc-shaped bend area of ​​the spring sheet 4 abuts against a side of the assembly 1 close to the mounting body 2;

[0048] like Figure 2 As shown, the raised part of the spring sheet 4 is inclined in the direction of rotation when the assembly 1 is locked, that is, when the assembly 1 rotates, the inner wall and the free end of the spring sheet 4 slide and rub, and no obstruction occurs. When it rotates in the opposite direction, the arc-shaped bend of the free end can effectively prevent the free end of the spring sheet 4 from blocking the rotation of the assembly 1.

[0049] In some embodiments, one end of the buckle slot 301 is a avoiding notch for allowing the hook body at the front end of the buckle 104 to pass through, and the other end is a limiting opening for allowing the rod part of the buckle 104 to pass through and limiting the hook part of the buckle 104 to pass through;

[0050] like Figure 6 and Figure 7 As shown, the length direction of the hook part of the buckle 104 is perpendicular to the rotation direction of the assembly 1, and the width of the avoidance notch is larger than the limiting opening. When the assembly 1 is assembled, the buckle 104 is aligned with the avoidance notch so that the hook part of the buckle 104 passes through the buckle slot 301, and then the assembly 1 is rotated to move the hook part of the buckle 104 to the position of the limiting opening, thereby limiting the hook part of the buckle 104 from disengaging from the buckle slot 301, that is, completing the combination and limiting of the buckle 104 and the buckle slot 301, and at this time the relative position of the assembly 1 and the mounting body 2 is locked.

[0051] In some embodiments, the width of each part of the snap groove hole 301 is consistent, and the length direction of the hook part of the snap 104 is the same as the direction in which the snap 104 is to be rotated. When the snap 104 penetrates through the snap groove hole 301, the positive projection of the hook body of the snap 104 is within the snap groove hole 301. When the assembly 1 rotates, only the positive projection of the rod part of the snap 104 remains within the snap groove hole 301. At this time, the hook part abuts against the inner wall of the snap groove hole 301, which also plays a limiting role. The above solutions also fall within the protection scope of this application.

[0052] In some embodiments, the working surface of the hook part of the snap 104 is a wedge surface; the gap between the wedge surface and the assembly 1 decreases sequentially from front to back;

[0053] As Figure 5 shown, the working surface of the hook part of the snap 104 is a wedge surface. As the assembly 1 rotates, the overlapping area between the working surface of the hook part and the mounting body 2 near the snap groove hole 301 increases. As the gap between the working surface of the hook part at the contact position and the assembly 1 continuously decreases, the normal pressure between the hook part and the contact surface of the snap groove hole 301 also continuously increases, and the frictional resistance continuously increases, thereby realizing the self-locking between the assembly 1 and the mounting body 2;

[0054] When disassembling the assembly 1, by pressing the corresponding position of the snap 104, the normal pressure between the hook part and the mounting body 2 can be reduced, thereby reducing the frictional force between the two, and then the assembly 1 can be rotated in the reverse direction to disengage it from the mounting body 2.

[0055] In some embodiments, a circular mounting groove 3 is provided on the surface of the mounting body 2, and the snap groove hole 301 is provided at the bottom of the mounting groove 3;

[0056] A flanging is provided on the outer periphery of the assembly 1. The outer diameter of the flanging is not greater than the inner diameter of the mounting groove 3, and the snap 104 is provided at the end of the flanging;

[0057] As Figure 1 and Figure 2 shown, by providing the mounting groove 3, the mounting position of the assembly 1 is preliminarily limited. After installation, the assembly 1 can be embedded in the mounting groove 3, forming a complete plane on the surface of the mounting body 2, further improving the aesthetics.

[0058] In some embodiments, a vertical protrusion is provided at the bottom of the mounting groove 3, a limiting groove 302 is provided on the side wall of the vertical protrusion, and a cylindrical limiting rib 103 is provided on the inner wall of the flanging; when the snap 104 is completely clamped in the snap groove hole 301, the limiting rib 103 is clamped with the limiting groove 302;

[0059] The vertical protrusion is a long strip-shaped arc structure, and the surface of the vertical protrusion upstream of the limiting groove 302 is a wedge surface.

[0060] As Figure 6 and Figure 7 shown, by setting the limiting rib 103 and the limiting groove 302, when the limiting rib 103 rotates with the assembly 1 and completes the assembly with the limiting groove 302, the rotational resistance of the assembly 1 will change suddenly. As Figure 6 shown, the vertical protrusion upstream of the limiting groove 302 is not a wedge-shaped surface. Then, when the limiting rib 103 contacts and slides on the wedge-shaped surface, its normal pressure will gradually increase, and the frictional resistance will increase. When the limiting rib 103 enters the limiting groove 302, the limiting rib 103 disengages from the wedge-shaped surface, and the normal pressure between the two changes suddenly, resulting in a sudden change in the frictional resistance. This change can be directly fed back to the operator to avoid rotating to the set position and stop rotating. Moreover, the limiting groove 302 can also limit the rotation of the limiting rib 103 to prevent it from reversing in the natural state, that is, to prevent the assembly 1 from detaching from the mounting body 2 and ensure that after the two are assembled, they have a relatively stable relative position relationship.

[0061] In some embodiments, as Figure 6 and Figure 7 shown, a plurality of groups of support protrusions 303 are arranged in an annular array at the bottom of the mounting groove 3 for abutting against the inner wall of the flanging;

[0062] The flanging of the assembly 1 is a cylindrical structure. During assembly, the inner wall of the flanging is supported by the support protrusions 303, which helps to ensure that the position of its rotation axis is fixed, reduces the friction between the rod part of the buckle 104 and the groove wall of the buckle slot 301, and also avoids breaking of the rod part of the buckle 104.

[0063] In addition to the quick-release rotary buckle structure disclosed in each of the above embodiments, the present invention also provides a display screen bracket including the above quick-release rotary buckle structure. The structure of the display screen bracket is as Figure 8 shown. For the structures of other parts, please refer to the prior art and will not be elaborated herein.

[0064] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0065] The above has introduced the quick-release rotary buckle structure and the display screen bracket provided by the present invention in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
