Description

Technical Field

[0001] This utility model relates to the field of folding bracket technology, and in particular to a retractable folding bracket. Background Technology

[0002] A folding stand is a support device that can be folded and unfolded, commonly used to support and secure items, and for easy carrying or storage. Folding stands have applications in many situations, such as supports for electronic devices and camera equipment. They are designed to provide stable support while easily folding into a compact form for convenient transport and storage. Currently, folding stands for electronic devices typically support mobile phones or tablets for watching videos, making video calls, or reading. They are usually angle-adjustable and fold into a flat structure for easy portability; for larger devices like laptops, they provide support while also improving heat dissipation and offering a more ergonomic operating angle. Chinese patent application CN202022407150.8 discloses a folding stand, comprising: a first folding plate, a second folding plate, a third folding plate, a first connecting member pivotally connecting the first and second folding plates, and a second connecting member pivotally connecting the second and third folding plates; both the first and second connecting members include connecting bolts, locking nuts, and washers; the first and second folding plates are fixed by the locking nuts after the connecting bolts pass through the connecting grooves, washers, and first connecting seats; the third and second folding plates are fixed by the locking nuts after the connecting bolts pass through the connecting grooves, washers, and second connecting seats; a limiting post is provided on the functional part. This utility model, through the cooperation between the connecting members and the first and second connecting seats, achieves the purpose of portable folding and free adjustment of the angle and height of the mobile phone stand.

[0003] However, the first folding plate, also known as the support plate, of the aforementioned folding bracket cannot be adaptively adjusted according to the size of the load. This limits the application scenarios of this type of folding bracket, making it unable to stably support devices of various sizes, such as mobile phones, tablets, and laptops, and thus limiting its versatility. Utility Model Content

[0004] Therefore, it is necessary to provide a telescopic folding bracket to address the technical problem of insufficient versatility of existing folding brackets.

[0005] A retractable folding bracket includes a base, a support mechanism, and a folding mechanism. One end of the folding mechanism is connected to the base, and the other end of the folding mechanism is connected to the support mechanism.

[0006] The support mechanism includes a first support plate, a second support plate, and a telescopic assembly. One end of the first support plate is connected to the folding mechanism, and the other end of the first support plate is connected to one end of the telescopic assembly. The second support plate is connected to the other end of the telescopic assembly relative to the first support plate.

[0007] The telescopic assembly includes a movable part and several fixed parts. The fixed parts are respectively disposed on both sides of the first support plate, and the two sides of the movable part are slidably engaged with the fixed parts.

[0008] The second support plate is located at the end of the movable part that faces away from several fixed parts.

[0009] In one embodiment, the aforementioned movable component includes a mounting portion and two slide rail portions. The two slide rail portions are respectively disposed at both ends of one side edge of the mounting portion, and the two slide rail portions are arranged parallel to each other.

[0010] In one embodiment, the two slide rails are slidably engaged with several fixing members on both sides of the first support plate; the second support plate is mounted on the surface of the mounting part.

[0011] In one embodiment, the aforementioned fasteners are provided as four, with the four fasteners arranged in pairs on both sides of the first support plate, and each slide rail part slidingly engaging with the two fasteners on the corresponding side.

[0012] In one embodiment, each of the slide rails is provided with a groove, and the groove is configured as a through groove structure extending along the length of the corresponding slide rail.

[0013] In one embodiment, the aforementioned groove can slide into contact with the side surface of the corresponding fastener.

[0014] In one embodiment, each of the above-mentioned fasteners includes a limiting post and a gasket. One end of the limiting post is connected to the bottom surface of the first support plate, and the other end of the limiting post extends a predetermined distance away from the first support plate to form a limiting head. The side surface of the limiting post slides in cooperation with the corresponding slide groove. The gasket is sleeved on the side surface of the limiting post and is disposed between the slide rail and the corresponding limiting head.

[0015] In one embodiment, each of the above-described fasteners further includes a buffer member, which is sleeved on the side surface of the corresponding limiting post and disposed between the gasket and the limiting head.

[0016] In one embodiment, the first tray is provided with a plurality of anti-slip pads, which are disposed on the top side surface of the first tray.

[0017] In one embodiment, the first tray is further provided with a plurality of support rods, which are disposed at the edge of the first tray facing away from the second tray, and each support rod extends a predetermined distance away from the top surface of the first tray.

[0018] In one embodiment, the second tray is made of an anti-slip material.

[0019] In one embodiment, the folding mechanism is configured as a support arm, one end of which is hinged to the top surface of the base; the other end of which is hinged to the bottom surface of the first support plate.

[0020] In one embodiment, the base is provided with a turntable, the bottom end of which is rotatably connected to the top side surface of the base, and the top end of which is hinged to the corresponding end of the support arm.

[0021] The aforementioned retractable folding bracket achieves folding and unfolding between the support mechanism and the base through a folding mechanism, thereby enabling the support mechanism to be raised, lowered, and angled relative to the base. The support mechanism includes a first support plate, a second support plate, and a telescopic component. One end of the first support plate is connected to the folding mechanism, and the other end is connected to one end of the telescopic component. The second support plate is connected to the other end of the telescopic component relative to the first support plate. Thus, the distance between the first and second support plates can be adjusted via the telescopic component. When the second support plate retracts to its near-end relative to the first support plate via the telescopic component, the first support plate and the second support plate form an initial support surface. When the second support plate extends to its far-end relative to the first support plate via the telescopic component, the first support plate and the second support plate form a larger support surface, enabling the support mechanism to stably support loads of different volumes and contact areas, effectively expanding the application scenarios of this retractable folding bracket.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0032] Please see Figures 1 to 4 This utility model discloses a retractable folding bracket 10, which includes a base 100, a support mechanism 200, and a folding mechanism 300. One end of the folding mechanism 300 is connected to the base 100, and the other end of the folding mechanism 300 is connected to the support mechanism 200. Thus, the support mechanism 200 can be folded and unfolded relative to the base 100 through the folding mechanism 300, thereby realizing the lifting and angle adjustment of the support mechanism 200 relative to the base 100. Specifically, the support mechanism 200 includes a first support plate 210, a second support plate 220, and a telescopic component 230. One end of the first support plate 210 is connected to the folding mechanism 300, and the other end of the first support plate 210 is connected to one end of the telescopic component 230. The second support plate 220 is connected to the other end of the telescopic component 230 relative to the first support plate 210. Thus, the distance between the first support plate 210 and the second support plate 220 can be adjusted by the telescopic component 230. When the second support plate 220 is retracted to the near end relative to the first support plate 210 via the telescopic component 230, the first support plate and the second support plate form an initial support surface. When the second support plate 220 is stretched to the far end relative to the first support plate 210 via the telescopic component 230, the first support plate and the second support plate form a larger support surface. This allows the support mechanism 200 to stably support loads of different volumes and contact areas, effectively expanding the application scenarios of the telescopic folding bracket 10 of this utility model.

[0033] Furthermore, the telescopic component 230 includes a movable member 231 and several fixed members 232. The fixed members 232 are respectively disposed on both sides of the first support plate 210. The two sides of the movable member 231 are slidably engaged with the fixed members 232, thereby allowing the movable member 231 to reciprocate relative to the first support plate 210 via the fixed members 232. Specifically, the second support plate 220 is disposed at the end of the movable member 231 facing away from the fixed members 232. Thus, the second support plate 220 can reciprocate relative to the first support plate 210 in a preset direction and with a preset amplitude as the movable member 231 moves, thereby realizing the telescopic function between the second support plate 220 and the first support plate 210.

[0034] Furthermore, the movable component 231 includes a mounting portion 2311 and two slide rail portions 2312. The two slide rail portions 2312 are respectively disposed at both ends of one edge of the mounting portion 2311, and are arranged parallel to each other. Specifically, the two slide rail portions 2312 are slidably engaged with several fixing members 232 on both sides of the first support plate 210, thereby allowing the mounting portion 2311 to reciprocate relative to the first support plate 210 via the two slide rail portions 2312; the second support plate 220 is mounted on the surface of the mounting portion 2311, thereby realizing the telescopic function between the second support plate 220 and the first support plate 210. In one embodiment, four fixing members 232 are provided, with the four fixing members 232 arranged in pairs on both sides of the first support plate 210. Each slide rail portion 2312 is slidably engaged with the two fixing members 232 on the corresponding side, thereby further improving the connection stability between the slide rail portion 2312 and the first support plate 210.

[0035] Furthermore, each slide rail portion 2312 is provided with a slide groove a, which is a through groove structure extending along the length direction of the corresponding slide rail portion 2312. Specifically, the slide groove a can slide and engage with the side surface of the corresponding fixing member 232, thereby realizing the reciprocating sliding of the movable member 231 between several fixing members 232.

[0036] Furthermore, each fixing member 232 includes a limiting post 2321 and a gasket 2322. One end of the limiting post 2321 is connected to the bottom surface of the first support plate 210, and the other end of the limiting post 2321 extends a predetermined distance away from the first support plate 210 to form a limiting head 2324. The side surface of the limiting post 2321 slides in cooperation with the corresponding slide groove a, so that the limiting post 2321 can reciprocate relative to the corresponding slide groove a. The gasket 2322 is sleeved on the side surface of the limiting post 2321, and the gasket 2322 is disposed between the slide rail part 2312 and the corresponding limiting head 2324 to buffer the pressure between the limiting head 2324 and the corresponding slide rail part 2312. Specifically, each fixing member 232 also includes a buffer member 2323, which is sleeved on the side surface of the corresponding limiting post 2321. Furthermore, the buffer member 2323 is disposed between the gasket 2322 and the limiting head 2324, thereby further improving the buffering performance of the limiting head 2324 between the slide rail and the slide rail.

[0037] Furthermore, the first pallet 210 is provided with a plurality of anti-slip pads 211. The plurality of anti-slip pads 211 are disposed on the top side surface of the first pallet 210. When the load object is placed on the support mechanism 200, the load object contacts the top side surface of the first pallet 210. The plurality of anti-slip pads 211 can increase the friction between the first pallet 210 and the load object, thereby improving the support stability of the first pallet 210 for the load object.

[0038] Furthermore, the first pallet 210 is also provided with a plurality of support rods 212, which are disposed on the edge of the first pallet 210 facing away from the second pallet 220. Each support rod 212 extends a predetermined distance away from the top surface of the first pallet 210, thereby forming a lateral support structure relative to the load object, further preventing the load object from sliding out laterally from the first pallet 210.

[0039] Furthermore, the second tray 220 is made of anti-slip material, which, together with the first tray 210 and several anti-slip pads 211 on its surface, further enhances the anti-slip performance of the support mechanism 200.

[0040] Furthermore, the folding mechanism 300 is configured as a support arm, one end of which is hinged to the top surface of the base 100; the other end of which is hinged to the bottom surface of the first tray 210, thereby enabling the first tray 210 to be adjusted in height and angle relative to the base 100.

[0041] Furthermore, the base 100 is provided with a turntable 110, the bottom end of which is rotatably connected to the top surface of the base 100, and the top end of which is hinged to the corresponding end of the support arm. Thus, the support arm can rotate relative to the base 100 via the turntable 110, thereby further expanding the angle adjustment range between the support mechanism 200 and the base 100.

[0042] In summary, the retractable folding bracket disclosed in this utility model achieves folding and unfolding between the support mechanism and the base through a folding mechanism, thereby realizing the lifting and angle adjustment of the support mechanism relative to the base. The support mechanism includes a first support plate, a second support plate, and a telescopic component. One end of the first support plate is connected to the folding mechanism, and the other end of the first support plate is connected to one end of the telescopic component. The second support plate is connected to the other end of the telescopic component relative to the first support plate. Thus, the distance between the first and second support plates can be adjusted by the telescopic component. When the second support plate is retracted to the near end relative to the first support plate by the telescopic component, the first support plate and the second support plate form an initial support surface. When the second support plate is extended to the far end relative to the first support plate by the telescopic component, the first support plate and the second support plate form a larger support surface, thereby enabling the support mechanism to stably support loads of different volumes and contact areas, effectively expanding the application scenarios of the retractable folding bracket of this utility model.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
