Description

Technical Field

[0001] The invention relates to a friction self-locking reading bracket, belonging to the technical field of office appliances. Background Art

[0002] With the development of science and technology and the progress of society, people now pay more attention to health. They pay more attention to the health of their neck, spine and wrists when using and reading laptops, tablets, mobile phones and books. Most people will be equipped with ordinary notebook reading stands at this time to adjust them to a healthy and comfortable angle.

[0003] Existing notebook reading stands are usually independent structures from the desktop, occupying a large desktop surface space and being inconvenient to store. Generally, office workers or home users only have one desk or table, and some desktop notebook stands will inevitably affect the desktop space requirements for other work when not in use.

[0004] The Chinese invention patent application with application publication number CN117397932A discloses a desktop and desk with an integrated laptop stand. The laptop reading stand is stored in a hole in the middle of the desktop, which greatly destroys the flatness of the desktop and creates a considerable number of sanitary dead corners, which will bring great hygiene and sanitation risks when in use.

[0005] The Chinese utility model patent with authorization announcement number CN220623452U discloses a reading stand that can be quickly disassembled, assembled and positioned. When disassembling and repositioning, the compression screw must be repeatedly tightened and loosened, which consumes a lot of physical strength and time, and the operation is laborious and complicated. In addition, a tightening screw is provided on the reading stand, so there must always be a gap between the bottom stand and the protruding or open groove slide rail that slides together. Due to the manufacturing precision of furniture products and to adapt to climate change, this gap is relatively large. Due to the distance magnification effect of the support legs and the support upper plate, this gap effect is magnified by dozens of times or even dozens of times, causing the stand system to shake more and lack stability, which can easily cause items such as laptops, tablets, PADs, mobile phones and books placed on the support upper plate to shake or slide, affecting the user experience. Summary of the invention

[0006] The purpose of the present invention is to provide a friction self-locking reading stand which does not damage the flatness of the desktop and is convenient for installation and adjustment with the desktop and can be quickly disassembled and positioned.

[0007] To solve the above problems, the technical solution adopted by the present invention is: a friction self-locking reading bracket, including 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 its 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 end 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 attached to 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 attachment to the table top; in the state where 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 the bottom bracket can be detached from the table top. When the present invention is used, it is installed on the table top, without the need to open 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 since the installation groove on the present invention penetrates through its left and right ends, it can be installed and removed from the end of the table top, or can also be installed and removed from other positions on the edge of the table top, realizing the installation and disassembly during use, facilitating the installation and disassembly of the present invention, the present invention can adjust its position on the table top as needed, and this adjustment is to lift the bottom bracket upward and then drag the bottom bracket to move along the edge of the table top to the required position to complete the positioning, without the need for other means such as tightening bolts, etc., and its position adjustment on the table top is convenient.

[0008] As a further improvement of the present invention, the vertical dimension of the installation groove 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 attached to the surface of the table top in the use state and generates friction self-locking with the surface of the table top; in the state where the bottom bracket is manually operated to be separated from the table top at the open end of the installation groove, there is a gap between the top of the friction protrusion and the surface of the table top. By setting the friction protrusion, the present invention can increase the vertical dimension of the installation groove, while keeping the bottom bracket in contact with the upper and lower surfaces of the table top simultaneously in the use state, and when the present invention is detached from the table top, the friction between the present invention and the table top is reduced or completely eliminated.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. Example 1

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

[0029] As shown Figures 1 to 3 in the figure, the bottom bracket 1 of this embodiment is in the shape of a cuboid as a whole. 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, the bottom bracket 1 is held by hand, the installation groove 4 of the bottom bracket 1 is directed towards the edge of the table top 5, and the bottom bracket 1 is pushed towards the table top 5 so that the edge of the table top 5 extends into the installation groove 4.

[0030] As shown Figures 1 to 3 in the figure, the top end of the supporting leg 3 of this embodiment is inclined towards the opening side of the installation groove 4, the supporting upper plate 2 is inclined, and the supporting upper plate 2 and the bottom bracket 1 are respectively located on both sides of the supporting leg 3, so that the overall center of gravity of this embodiment is biased towards one side of the table top 5. Under the action of the gravity of the supporting upper plate 2 and the supporting leg 3, the installation groove 4 side of the bottom bracket 1 inclines downward, so that the upper and lower surfaces of the open end of the installation groove 4 of the bottom bracket 1 are respectively attached to the upper and lower surfaces of the table top 5, and the bottom bracket 1 is positioned on the table top 5 through the friction self-locking generated by the attachment to the upper and lower surfaces of the table top 5 respectively. During 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 shown Figures 1 to 3 in the figure, in the state where the bottom bracket 1 is manually operated until the open end of the installation groove 4 is separated from the table top, 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 shown Figures 1 to 3As shown, in this embodiment, the upper and lower dimensions of the mounting groove 4 are larger than the thickness of the table top 5, and the end portion of the lower side of the mounting groove 4 protrudes upward to form a friction protrusion 6, and the left-right length of the friction protrusion 6 is equal to the left-right length of the bottom bracket 1, and the top of the friction protrusion 6 fits with the lower surface of the table top 5 in the use state, and produces friction self-locking with the lower surface of the table top 5, and cooperates with the friction self-locking generated by the fit between the upper surface of the mounting groove 4 and the upper surface of the table top 5 to fix the bottom bracket 1 and the table top 5. 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 table top 5. In this state, the friction between the bottom bracket 1 and the table top 5 is small, and when the bottom bracket 1 is slightly lifted upward, so that the upper surface of the mounting groove 4 is out of contact with the table top 5 and the friction protrusion 6 is out of contact with the lower surface of the table top 5, there is no friction between the bottom bracket 1 and the table top 5.

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

[0034] like Figures 1 to 3 As shown, there are two supporting legs 3 in this embodiment, and the two supporting legs 3 are both in the shape of oblong plates. The two supporting legs 3 are parallel and have equal angles with the vertical direction. Fixed seats 8 are fixedly provided on the tops of the left and right ends of the bottom bracket 1. The fixed seats 8 in this embodiment are plate-shaped and fixedly connected to the bottom bracket 1. The bottom ends of the two supporting legs 3 are respectively connected to the two fixed seats 8, and the top ends of the two supporting legs 3 are connected to the supporting upper plate 2.

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

[0036] like Figures 1 to 3As shown, in this embodiment, the bottom of the supporting upper plate 2 is bent in a direction away from the supporting leg 3 to form a supporting flange 13, and the flange 13 is perpendicular to the supporting upper plate 2. A non-slip baffle 14 made of a silicone strip is provided on the supporting flange 13. The length of the non-slip baffle 14 is less than or equal to the length of the flange 13, and can be fixed to the flange 13 by gluing. In the use state, the bottom end of the electronic product or book is set on the non-slip baffle 14 and supported upward by the supporting flange 13. The non-slip baffle 14 can effectively prevent the electronic product or book from sliding off. In this embodiment, a plurality of heat dissipation holes 7 are opened on the supporting upper plate 2, which are convenient for heat dissipation of the electronic product when used to support the electronic product. Example 2

[0037] This embodiment is a further improvement made on the basis of the embodiment 1. Compared with the embodiment 1, the difference of this embodiment is that the fixing method of the supporting leg 3 and the fixing seat 8 is different. Figure 5 and Figure 6 As shown, in this embodiment, mounting holes A are provided on both fixing 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 fixing seat 8 by means of a locking bolt 11 passing through the mounting holes A and B and a nut threadedly matched with the locking bolt 11. Loosening the nut can loosen the support leg 3 and the fixing seat 8, which can be used to adjust the angle between the support leg 3 and the bottom bracket 1. Tightening the nut can fix the support leg 3 and the fixing 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 reference can be made to embodiment 1, which will not be described in detail in this embodiment.
