The utility model relates to a desk reading frame with stepless overturning adjustment, which is shown in figures 1-3 and comprises:

the mounting rack 1 is used for being connected with a desk;

the bottom of the object placing plate 2 is provided with a clamping groove which is mainly used for placing books and also can be used for placing articles such as mobile phones, tablet computers and the like;

the mounting frame 1 can be mounted on a bookshelf layer plate of a desk through screws (shown in fig. 1), or in some cases, the mounting frame 1 can be directly abutted on a tabletop to serve as a support for the opposite panel 2 (shown in fig. 2);

the mounting frame 1 and the object placing plate 2 are connected through a connecting structure, the object placing plate 2 can rotate relative to the mounting frame 1 through the connecting structure, and the angle between the mounting frame 1 and the object placing plate 2 is fixed when a person stops applying force.

The specific structure of the connection structure is shown in fig. 4-6, and includes:

the connecting column 3, one end side surface is a first connecting surface 31, and the other end surface is provided with a threaded column 32;

the fixing nut 7 is sleeved on the threaded column 32 and is attached with the elastic metal sheet 6.

The specific principle of the stepless regulating function of the reading frame is as follows: in a normal state, the elastic metal sheet 6 applies axial pressure to the damping sheet 5, so that certain friction force is generated between the damping sheet 5 and the end surface of the sleeve 4, and relative rotation between the connecting column 3 and the sleeve 4 is restrained, namely, the angle between the mounting frame 1 and the object placing plate 2 is fixed; when a book is placed, because the weight of the book is small, the moment generated by the weight of the book is insufficient to overcome the moment generated by the friction force between the damping fin 5 and the end face of the sleeve 4, and therefore the connecting column 3 and the sleeve 4 still cannot rotate, namely the mounting frame 1 and the object placing plate 2 are kept fixed; when a person pulls the object placing panel 2 manually, the moment generated by the person on the object placing panel 2 is large enough to overcome the moment generated by the friction force between the damping fin 5 and the end face of the sleeve 4, so that the connecting column 3 and the sleeve 4 can rotate, namely, the angle between the mounting frame 1 and the object placing panel 2 can be adjusted, and after the person removes the force application, the connecting column 3 and the sleeve 4 return to the stop state after the friction of the damping fin 5 is eliminated, and the angle adjustment is completed. The damping fin 5 is usually made of metal, so that friction can be increased, and the friction is not too large to cause the connecting column 3 and the sleeve 4 to be too hard to rotate. When the weight of the book is great, can inwards screw fixation nut 7, make it compress tightly elasticity sheetmetal 6 more, then elasticity sheetmetal 6 deformation grow and produce bigger pressure to damping fin 5 to make the friction between damping fin 5 and sleeve 4 section increase, and then promote the bearing capacity of thing panel 2.

The mounting bracket 1 and the spliced pole 3, put thing panel 2 and sleeve 4 when mutual fixed connection, can adopt multiple connection forms such as bonding, welding, screw fixation, this reading frame provides a structure form that the installation is most simple and convenient: a first connecting cylinder 11 is arranged at the edge of one side of the mounting frame 1, and a first connecting surface 31 of the connecting column 3 extends into the first connecting cylinder 11; a second connecting cylinder 21 is arranged at the top of the object placing plate 2, and a second connecting surface 42 of the sleeve 4 extends into the second connecting cylinder 21; when the connecting structure is installed, the connecting structure is only required to be placed in the opening parts of the first connecting cylinder 11 and the second connecting cylinder 21, so that the operation of personnel is facilitated. If necessary, the opening parts of the first connecting cylinder 11 and the second connecting cylinder 21 can be provided with decorative blocks, so that the attractive appearance of the reading frame is ensured.

Preferably, the first clamping strip 33 and the second clamping strip 43 protruding outwards are respectively arranged on the first connecting surface 31 and the second connecting surface 42, the outer diameter of the first clamping strip 33 is slightly larger than that of the first connecting cylinder 11, the outer diameter of the second clamping strip 43 is slightly larger than that of the second connecting cylinder 21, and the connecting column 3 and the first connecting cylinder 11, the sleeve 4 and the second connecting cylinder 21 are fixed more reliably through the formed interference fit. It is preferable that the first and second locking strips 33 and 43 extend axially along the screw column 32, and since the connecting column 3 and the sleeve 4 move axially to be put into the first and second connecting cylinders 11 and 21 at the time of installation, the difficulty of putting into the first and second locking strips 33 and 43 extending axially can be reduced, and the difficulty of rotating the connecting column 3 and the sleeve 4 relative to the first and second connecting cylinders 11 and 21 can be increased, so that the reliability of fixing can be further improved.

Preferably, the first connecting cylinder 11, the second connecting cylinder 21 and the connecting structure are all two, and the two first connecting cylinders 11 are all located between the two second connecting cylinders 21, so after the installation frame 1 is fixed, the two first connecting cylinders 11 and the two second connecting cylinders 21 cannot move, and the connecting structure is prevented from falling off.

A plurality of first grooves 52 are preferably provided on the side of each damping fin 5 facing the end face of the sleeve 4, so as to increase the friction between the damping fin 5 and the end face of the sleeve 4. The end surface of the sleeve 4 is preferably also provided with a plurality of second grooves 44, so that friction force is further improved, and a certain angle corresponding relation can be generated between the second grooves 44 and the first grooves 52 when the second grooves 44 are arranged, so that when the first grooves 52 and the second grooves 44 are aligned, friction force is obviously increased, and a person can feel obvious frustration when rotating the object placing panel 2 for a certain angle, so that feedback of the rotating angle is generated to the person.
