Description

Technical Field

[0001] This utility model relates to the field of card holder technology, specifically to a card rotating holder. Background Technology

[0002] With the widespread application of card products in games, collectibles, education, and film and television derivatives, card protection devices have gradually become an important means of enhancing product display and extending product lifespan. Existing card protection devices mainly employ three basic structures: frame-style, side-standing, and upright. Frame-style display stands use front and back panels to clamp and secure cards. Their closed back panel design necessitates complete disassembly when changing cards, and frequent disassembly and reassembly can easily cause stripped screws or broken clips. The process also requires two hands and is time-consuming. While side-standing and upright display devices use an open structure for easy access, their fixed tilt angle design (typically 60-90°) cannot adapt to different scenario requirements.

[0003] Therefore, there is an urgent need to develop a display device that has multi-dimensional adjustment capabilities, supports rapid costume changes, and is compatible with irregularly shaped cards. Utility Model Content

[0004] In view of this, the present invention proposes a card rotating bracket, which allows for free and flexible adjustment of the display angle of the cards according to display needs, and enables quick card loading and unloading without complicated disassembly and assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A card rotating bracket includes: a fixed base; a turntable rotatably mounted on top of the fixed base; and a folding bracket, the folding bracket including a connecting base, a back plate, a base plate, and a support member. The bottom end of the connecting base is fixed to the top surface of the turntable, and the top end of the connecting base is vertically provided with a fixed shaft. The bottom end of the back plate and one end of the base plate are coaxially mounted to the fixed shaft through a first damping pivot structure, forming an L-shaped bearing space that can open and close relative to each other around the fixed shaft. The top end of the support member is hinged to the back side of the back plate through a second damping pivot structure, and the bottom end of the support member forms an adjustable support end that can abut against the top surface of the turntable.

[0007] To better achieve the above technical solution, the bottom surface of the fixing base is further covered with an adhesive layer, and the surface of the adhesive layer is covered with a peelable release paper.

[0008] Furthermore, the bottom surface of the turntable is coaxially provided with an annular receiving groove, the central axis of which is fixedly connected to a first rotating shaft, and the top surface of the fixed seat extends coaxially to form a convex ring. A bearing is embedded in the convex ring, and the first rotating shaft and the inner ring of the bearing are interference-fitted to form a rotating pair. The outer wall of the convex ring is accommodated in the receiving groove with a clearance fit to the inner wall of the receiving groove.

[0009] Furthermore, the top surface of the turntable is provided with a positioning groove, the contour of the groove wall is adapted to the cross-sectional shape of the adjustable support end of the support member, and is used to snap and fix the adjustable support end of the support member.

[0010] Furthermore, there are multiple positioning slots, which are spaced apart along the inclined angle of the back plate.

[0011] Furthermore, the bottom plate has an upwardly extending limiting part at the end away from the fixed axis, which is used to abut the bottom edge of the card.

[0012] Furthermore, the limiting part has an identification area on the side opposite to the fixed axis, and the identification area is used to carry card attribute identification marks.

[0013] Furthermore, the turntable is provided with at least one rotating handle radially on its side.

[0014] The beneficial effects of this utility model are:

Detailed Implementation

[0021] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0022] Please see Figures 1 to 3 This utility model discloses a card rotating bracket, including a fixed base 10, a turntable 20, and a folding bracket.

[0023] The turntable 20 is rotatably mounted on top of the fixed base 10. The folding bracket includes a connecting base 30, a back plate 40, a base plate 50, and a support member 60. The bottom end of the connecting base 30 is fixed to the top surface of the turntable 20, and the top end of the connecting base 30 is vertically provided with a fixed shaft 31. The bottom end of the back plate 40 and one end of the base plate 50 are coaxially mounted to the fixed shaft 31 through a first damping pivot structure, forming an L-shaped bearing space that can be opened and closed relative to the fixed shaft 31. The top end of the support member 60 is hinged to the back of the back plate 40 through a second damping pivot structure. The bottom end of the support member 60 forms an adjustable support end, which can abut against the top surface of the turntable 20.

[0024] Specifically, the first damping pivot structure includes two first bushings 401 spaced apart at the bottom end of the back plate 40 and two second bushings 502 spaced apart at one end of the bottom plate 50. Both the first bushings 401 and the second bushings 502 are damped and fitted onto both ends of the fixed shaft 31, allowing both the back plate 40 and the bottom plate 50 to rotate around the fixed shaft 31. The second damping pivot structure includes a fixed bushing 402 fixed to the top of the back surface of the back plate 40 and a hinge shaft 403 that rotates through the fixed bushing 402 with damping. Both ends of the hinge shaft 403 are fixedly embedded in the top end of the support member 60, allowing the support member 60 to rotate around the central axis of the fixed bushing 402.

[0025] A card rotating bracket according to an embodiment of this utility model is specifically implemented as follows:

[0026] By rotating the back plate 40 and the base plate 50 in opposite directions, the base plate 50 is rotated to a horizontal position, serving as the base plane for card placement. Simultaneously, the back plate 40 can be rotated around the fixed axis 31 to form a specific angle with the base plate 50, depending on actual usage requirements. During this process, the support member 60 is simultaneously deployed. The adjustable support end of the support member 60, after deployment, rests against the upper surface of the turntable 20, forming a stable support structure through a three-point support principle, further enhancing the stability of the overall structure composed of the back plate 40 and the base plate 50. At this point, the back plate 40 and the base plate 50 together enclose an open card placement space.

[0027] This utility model provides a card rotating bracket. Because the angles of the back plate 40 and the base plate 50 are flexibly adjustable, users can adjust the cards to the optimal display angle according to different display needs, greatly enhancing the diversity of display effects. The open card placement space, compared to the traditional closed structure, completely eliminates spatial obstacles when changing cards. Users can easily and conveniently complete card replacement operations without disassembling any parts, improving usability. The turntable 20 is rotatably mounted on top of the fixed base 10. The rotation of the turntable 20 drives the folding bracket mounted on it to rotate synchronously, thereby achieving all-round display of cards from different positions and angles, effectively expanding the display range and meeting the needs of diverse display scenarios.

[0028] In an embodiment of this utility model, the bottom surface of the fixing base 10 is covered with an adhesive layer (not shown in the figure), and the surface of the adhesive layer is covered with a peelable release paper. When in use, the release paper is peeled off, and the card holder can be fixed by adhesive. In other optional embodiments, the bottom surface of the fixing base 10 may have an embedded magnet, which is fixed in a designated position by magnetic attraction, or the fixing base 10 may be placed in a designated position directly using its own support structure.

[0029] like Figure 2 and Figure 3As shown, a receiving groove 201 is formed on the bottom surface of the turntable 20. The receiving groove 201 with an annular structure is formed on the bottom surface of the turntable 20. The first rotating shaft 202 is fixedly connected to the central axis of the receiving groove 201. Preferably, the first rotating shaft 202 and the turntable 20 are integral structures. The top surface of the fixed seat 10 extends coaxially to form a convex ring 101. A bearing 102 is embedded in the convex ring 101. The first rotating shaft 202 and the inner ring of the bearing 102 are interference-fitted to form a rotating pair. The outer wall of the convex ring 101 and the inner wall of the receiving groove 201 are accommodated in the receiving groove 201 with a clearance fit. By rotating the first rotating shaft 202 in conjunction with the bearing 102, the frictional resistance of the turntable 20 during rotation can be effectively reduced, enabling 360° free rotation. The combination of the clearance fit receiving groove 201 and the convex ring 101 ensures flexible rotation of the turntable while enhancing the stability of the structure, preventing radial swaying during rotation, and ensuring that the card holder installed on the turntable 20 can achieve smooth and stable multi-angle display, thus improving the display effect and user experience.

[0030] like Figure 2 As shown, a positioning groove 203 is provided on the top surface of the turntable 20. The contour of the groove wall of the positioning groove 203 is adapted to the cross-sectional shape of the adjustable support end of the support member 60, and is used to engage and fix the adjustable support end of the support member 60. Preferably, there are multiple positioning grooves 203, which are spaced apart along the inclination angle of the back plate 40. When the adjustable support end is engaged in the positioning groove 203 at different positions, the back plate 40 is stably supported at different inclination angles.

[0031] In this embodiment of the invention, the bottom plate 50 has an upwardly extending limiting part 501 at the end away from the fixed axis. The limiting part 501 is used to abut against the bottom edge of the card. Specifically, the limiting part 501 and the bottom plate 50 form a V-shaped structure. In use, the limiting part 501 can tightly abut against the bottom edge of the card, limiting the displacement of the card through the three-point support principle, effectively improving the stability of the card placement. A marking area is provided on the side of the limiting part 501 away from the fixed axis. This marking area can be carried by means of pasted labels or laser etching, etc., to carry card attribute identification marks, product introductions, and other information, making it easy for users to quickly identify the card content.

[0032] In an embodiment of this utility model, the sidewall of the turntable 20 is provided with a plurality of radially extending rotary handles 204 at intervals along the circumferential direction, and a decorative ring 205 is embedded in the center of the rotary handle 204. The design of multiple rotary handles 204 can improve the convenience of users operating the turntable 20; the decorative ring 205 can enhance the aesthetic appearance of the product, combining functionality and decoration, and meeting the user's dual needs for the aesthetics and practicality of the display device.

[0033] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
