Description

Technical Field

[0001] This utility model relates to a friction self-locking reading stand, belonging to the technical field of office supplies. Background Technology

[0002] With the development of technology and the progress of society, people are now paying more attention to their health. When using laptops, tablets, mobile phones and books, they are more mindful of the health of their necks, spines and wrists. Most people will use a regular laptop reading stand to adjust the device to a healthy and comfortable angle.

[0003] Existing laptop reading stands and desktops are usually separate structures, which take up a lot of desktop space when in use and are extremely inconvenient to store. However, most office workers or home users only have one desk or study desk, and some desktop laptop stands will inevitably affect the desktop space required for other work when not in use.

[0004] Chinese invention patent application CN117397932A discloses a desktop and office desk with an integrated laptop stand. The laptop reading stand is stored in the middle of the desktop with an opening, which greatly damages the flatness of the desktop and creates a lot of hard-to-clean corners, posing a great cleaning and hygiene hazard during use.

[0005] Chinese utility model patent CN220623452U discloses a reading stand that is quick to assemble and reposition. However, its assembly, disassembly, and repositioning require repeated tightening and loosening of the clamping screws, which is extremely physically demanding and time-consuming. The operation is laborious and cumbersome. Furthermore, the presence of tightening screws inevitably creates a gap between the bottom support and the sliding contact rail (either protruding or slotted). Due to the manufacturing precision requirements of furniture products and the need to adapt to climate changes, this gap is relatively large. The distance between the support legs and the upper support plate amplifies this gap by tens of times, resulting in significant wobbling and instability. This can easily cause laptops, tablets, mobile phones, books, and other items placed on the upper support plate to shake or slip, negatively impacting the user experience. Summary of the Invention

[0006] The purpose of this invention is to provide a friction self-locking reading stand that can be quickly assembled, disassembled, and positioned without compromising the flatness of the desktop and is easy to install and adjust.

[0007] To solve the above problems, the technical solution adopted by the utility model is as follows: a friction self-locking reading bracket, which includes a bottom bracket, a supporting upper plate and at least one supporting leg; the top and bottom ends of the supporting leg are respectively connected to the bottom bracket and the supporting upper plate, and the supporting upper plate is used to place electronic products or books in the use state; a "C"-shaped installation groove penetrating through the left and right ends is opened horizontally on one side of the bottom bracket, and the bottom bracket is installed at the edge of the table top through the installation groove in the use state; the top of the supporting leg inclines to one side, and under the gravity of the supporting upper plate and the supporting leg, one side of the installation groove of the bottom bracket inclines downward, so that the upper and lower inner surfaces of the open end of the installation groove of the bottom bracket are respectively in contact with the upper and lower surfaces of the table top, and the bottom bracket is positioned on the table top through the friction self-locking generated by the contact with the table top; when the bottom bracket is lifted upward at the open end of the installation groove, the friction between the bottom bracket and the table top is reduced or disappears, and the bottom bracket can be horizontally moved along the edge of the table top to adjust its position on the table top or remove the bottom bracket from the table top. When the utility model is in use, it is installed on the table top, without the need to drill holes on the table top for storage, without damaging the flatness of the table top, avoiding the generation of sanitary dead corners on the table top, facilitating the cleaning of the table top, and the installation groove on the utility model penetrates through its left and right ends, so it can be installed and removed from the end of the table top or other positions on the edge of the table top, realizing the installation and disassembly during use, facilitating the installation and disassembly of the utility model. The utility model can adjust its position on the table top as needed, and this adjustment can be completed by lifting the bottom bracket upward and then dragging the bottom bracket to move along the edge of the table top to the required position, without the need for other means such as tightening bolts, and its position adjustment on the table top is convenient.

[0008] As a further improvement of the utility model, the size of the installation groove in the up and down direction is larger than the thickness of the table top, and a friction protrusion is formed by protruding into the installation groove at the end of the installation groove; the top of the friction protrusion is in contact with the surface of the table top in the use state and generates friction self-locking with the surface of the table top; when the bottom bracket is manually operated to the state where the open end of the installation groove is separated from the table top, there is a gap between the top of the friction protrusion and the surface of the table top. By setting the friction protrusion, the utility model can increase the size of the installation groove in the vertical direction, while keeping the bottom bracket in contact with the upper and lower surfaces of the table top in the use state, and reducing or completely eliminating the friction between the utility model and the table top when the utility model is removed from the table top.

[0009] As a further improvement of the utility model, there are two supporting legs; fixed seats are fixedly arranged at the tops of the left and right ends of the bottom bracket, the bottom ends of the two supporting legs are respectively connected to the two fixed seats, and the top ends of the two supporting legs are both connected to the supporting upper plate. The utility model uses two supporting legs to support the supporting upper plate, and the supporting upper plate is more stable.

[0010] As a further improvement of this utility model, two connecting lugs are fixed on the lower surface of the upper support plate. The top ends of the two support legs are rotatably connected to the upper support plate via damping shafts. The lower ends of the two support legs are respectively connected to two fixed seats via damping shafts. This utility model facilitates the connection between the support legs and the upper support plate by providing connecting lugs on the upper support plate. The damping shafts in this utility model allow the support legs to quickly return to a stable state after the angle of the support legs is adjusted.

[0011] As a further improvement of this utility model, mounting holes A are provided on both fixed seats, and mounting holes B are provided at the lower end of the support leg. The support leg is connected to the fixed seat by locking bolts passing through mounting holes A and B, and nuts that are threadedly engaged with the locking bolts. Loosening the nuts can be used to adjust the angle between the support leg and the bottom bracket. This utility model, by providing mounting holes A on the fixed seats and mounting holes B on the support legs, facilitates the passage of locking bolts and their engagement with nuts to fix the support legs. Simultaneously, the support legs can be adjusted by loosening the nuts.

[0012] As a further improvement of this utility model, it also includes a storage and fixing device, which is fixed to the lower surface of the tabletop and is used to store the bottom bracket, upper support plate, and support legs under the tabletop when not in use. This utility model is equipped with a storage and fixing device to facilitate storage when not in use.

[0013] As a further improvement of this utility model, the storage and fixing device consists of multiple hooks fixed to the underside of the tabletop, magnets fixed to the underside of the tabletop, or slots or grooves formed on the underside of the tabletop. The structure of the storage and fixing device facilitates the storage of items according to this utility model.

[0014] As a further improvement of this utility model, the bottom of the upper support plate is bent away from the support legs to form a support flange. A silicone strip is provided on the support flange as an anti-slip barrier. In use, the bottom of the electronic product or book rests on the anti-slip barrier and is supported upwards by the support flange. This utility model features a support flange for convenient support of electronic products or books, while the anti-slip barrier effectively prevents the electronic product or book from sliding off the upper support plate.

[0015] As an improvement of this invention, several heat dissipation holes are provided on the upper support plate. These holes facilitate heat dissipation for electronic products during use.

Detailed Implementation

[0027] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. Embodiment 1

[0028] As Figures 1 to 4 shown, the friction self-locking reading bracket of this embodiment includes a bottom bracket 1, a support upper plate 2, and at least one support leg 3. The top and bottom ends of the support leg 3 are respectively connected to the bottom bracket 1 and the support upper plate 2, supporting the support upper plate 2 on the bottom bracket 1. The support upper plate 2 is used to place electronic products or books in the use state.

[0029] As Figures 1 to 3 shown, in this embodiment, the bottom bracket 1 is in an overall cuboid shape. A "C"-shaped installation groove 4 penetrating through its left and right ends is opened horizontally on one side of the bottom bracket 1. In the use state, the bottom bracket 1 is installed at the edge of the table top 5 through the installation groove 4. In this embodiment, hold the bottom bracket 1, face the installation groove 4 of the bottom bracket 1 towards the edge of the table top 5, and push the bottom bracket 1 towards the table top 5 so that the edge of the table top 5 extends into the installation groove 4.

[0030] As Figures 1 to 3 shown, in this embodiment, the top end of the support leg 3 is inclined towards the opening side of the installation groove 4, the support upper plate 2 is inclined, and the support upper plate 2 and the bottom bracket 1 are respectively located on both sides of the support leg 3, making the overall center of gravity of this embodiment偏向 the table top 5 side. Under the action of the gravity of the support upper plate 2 and the support leg 3, the installation groove 4 side of the bottom bracket 1 is inclined downward, so that the upper and lower surfaces of the open end of the installation groove 4 of the bottom bracket 1 are respectively in contact with the upper and lower surfaces of the table top 5, and friction self-locking is generated by the contact with the upper and lower surfaces of the table top 5 respectively to position the bottom bracket 1 on the table top 5. When in use, the bottom bracket 1 will not move left and right or back and forth along the table top 5, so that this embodiment will not fall off the table top 5 during use.

[0031] As Figures 1 to 3 shown, in this embodiment, when the bottom bracket 1 is manually operated to the state where the open end of the installation groove 4 is separated from the desktop, the friction between the bottom bracket 1 and the table top 5 is reduced or disappears, and the bottom bracket 1 can be horizontally moved left and right along the edge of the table top 5 to adjust its position on the table top 5, or the bottom bracket 1 can be moved away from the table top 5 to disassemble the bottom bracket 1 from the table top 5.

[0032] As Figures 1 to 3As shown, in this embodiment, the dimensions of the mounting groove 4 are greater than the thickness of the tabletop 5. A friction protrusion 6 protrudes upward from the lower end of the mounting groove 4. The length of the friction protrusion 6 in the left-right direction is equal to the length of the bottom bracket 1 in the left-right direction. The top of the friction protrusion 6 is in contact with the lower surface of the tabletop 5 in the use state, and generates friction self-locking with the lower surface of the tabletop 5. Combined with the friction self-locking generated by the contact between the upper surface of the mounting groove 4 and the upper surface of the tabletop 5, the bottom bracket 1 and the tabletop 5 are fixed. In this embodiment, when the open end of the mounting groove 4 of the bottom bracket 1 is manually lifted upward, there is a gap between the top of the friction protrusion 6 and the lower surface of the tabletop 5. In this state, the friction between the bottom bracket 1 and the tabletop 5 is small. When the bottom bracket 1 is lifted slightly upward, so that the upper surface of the mounting groove 4 is out of contact with the tabletop 5 and the friction protrusion 6 is out of contact with the lower surface of the tabletop 5, there is no friction between the bottom bracket 1 and the tabletop 5.

[0033] like Figures 1 to 3 As shown, in this embodiment, the lower surface of the mounting groove 4 is inclined, and the end of the friction protrusion 6 is inclined upward. On the one hand, this can reduce the material required for manufacturing the bottom bracket 1, and on the other hand, reduce the overall weight of this embodiment and increase the size of the space inside the mounting groove 4.

[0034] like Figures 1 to 3 As shown, there are two support legs 3 in this embodiment. Both support legs 3 are oblong plate-shaped. The two support legs 3 are parallel and have the same angle with the vertical direction. Fixing seats 8 are fixedly installed at the top of both the left and right ends of the bottom bracket 1. In this embodiment, the fixing seats 8 are plate-shaped and fixedly connected to the bottom bracket 1. The bottom ends of the two support legs 3 are respectively connected to the two fixing seats 8, and the top ends of the two support legs 3 are connected to the upper support plate 2.

[0035] like Figures 1 to 3 As shown, in this embodiment, two connecting lugs 9 are welded and fixed on the lower surface of the upper support plate 2. The top ends of the two support legs 3 are rotatably connected to the two connecting lugs 9 by a damping shaft 10 for connection to the upper support plate 2. The lower ends of the two support legs 3 are respectively connected to two fixed seats 8 by a damping shaft 10.

[0036] like Figures 1 to 3As shown, in this embodiment, the bottom of the upper support plate 2 is bent away from the support leg 3 to form a support flange 13. The flange 13 is perpendicular to the upper support plate 2. A silicone strip anti-slip strip 14 is provided on the support flange 13. The length of the anti-slip strip 14 is less than or equal to the length of the flange 13 and can be fixed to the flange 13 by adhesive. In use, the bottom of the electronic product or book is placed on the anti-slip strip 14 and supported upward by the support flange 13. The anti-slip strip 14 can effectively prevent the electronic product or book from slipping off. In this embodiment, several heat dissipation holes 7 are provided on the upper support plate 2 to facilitate heat dissipation of the electronic product when it is used to support the electronic product. Example 2

[0037] This embodiment is a further improvement on Embodiment 1. The difference between this embodiment and Embodiment 1 lies in the different fixing methods of the support leg 3 and the fixed base 8. Figure 5 and Figure 6 As shown, in this embodiment, mounting holes A are provided on both fixed seats 8, and mounting holes B are provided at the lower end of the support leg 3. The support leg 3 is connected to the fixed seat 8 by locking bolts 11 passing through mounting holes A and B, and nuts that are threaded into the locking bolts 11. Loosening the nuts allows the support leg 3 to move loosely between itself and the fixed seat 8, which can be used to adjust the angle between the support leg 3 and the bottom bracket 1. Tightening the nuts fixes the support leg 3 to the fixed seat 8, preventing the support leg 3 from rotating relative to the bottom bracket 1. The structure of the rest of this embodiment is the same as that of Embodiment 1, and specific details can be found in Embodiment 1. This embodiment will not be described in detail. Example 3

[0038] This embodiment is a further improvement on embodiment 1 or embodiment 2. Compared with embodiment 1 or embodiment 2, this embodiment is provided with a storage and fixing device 12. The storage and fixing device 12 is fixed on the lower surface of the tabletop 5 and is used to store the bottom bracket 1, the upper support plate 2 and the support leg 3 under the tabletop 5 when not in use.

[0039] In this embodiment, the storage and fixing device 12 can be multiple hooks fixed to the lower surface of the tabletop 5, hooking the bottom bracket 1, the upper support plate 2, and the support leg 3 under the tabletop 5; the storage and fixing device 12 can also be a magnet fixed to the lower surface of the tabletop 5, attracting the bottom bracket 1, the upper support plate 2, and the support leg 3 to the lower surface of the tabletop 5; the storage and fixing device 12 can also be a slot or groove formed on the lower surface of the tabletop 5, inserting the bottom bracket 1, the upper support plate 2, and the support leg 3 into the slot or groove, thereby fixing them to the lower surface of the tabletop 5, such as... Figure 7As shown, the optimal storage and fixing device 12 in this embodiment consists of multiple hooks fixed to the lower surface of the tabletop 5. The structure of the remaining parts in this embodiment is the same as that in Embodiment 1 or Embodiment 2, and can be referred to Embodiment 1 or Embodiment 2 for details. This embodiment will not be described in detail. Example 4

[0040] This embodiment is a further improvement on embodiment 3. Compared to embodiment 3, this embodiment includes a support rod 15, such as... Figure 8 As shown, the upper end of the support leg 3 is connected to the upper support plate 2, and the lower end of the support leg 3 is rotatably connected to the upper part of the bottom bracket 1. One end of the support rod 15 is rotatably connected to the bottom bracket 1 or the upper support plate 2. In this embodiment, one end of the support rod 15 is rotatably connected to the upper support plate 2, and the other end of the support rod 15 is provided with a support column 16, which is perpendicular to the support rod 15. Two or more support grooves 17 are opened on the support leg 3. By rotating the support leg 3 and the support rod 15, the support column 16 is matched with different support grooves 17 to adjust the angle of the upper support plate 2. The structure of the remaining parts in this embodiment is the same as that in embodiment 3. For details, please refer to embodiment 3. This embodiment will not be described in detail.
