Description

Multifunctional support

Technical Field

The utility model relates to a study and official working instrument field, in particular to make things convenient for multi-functional support of study and work.

Background

At present, the known multifunctional support is composed of a clamping seat, a cantilever, a universal joint, a spring, a short arm and a panel. The bracket is connected to a desk or a bed head, which is convenient for people to study and entertain in daily life. However, due to the unreasonable design, the overall strength of the stand is insufficient, and the stand cannot meet the learning and working requirements of more functions, for example, the operation of a notebook computer cannot be performed thereon, and a person and the stand cannot be in an optimal relative position when in use.

SUMMERY OF THE UTILITY MODEL

In order to overcome the deficiencies of the prior art, the utility model provides a multifunctional support, this support can not only realize current multifunctional support's all efficiency to let the people when using the support, can be in a comfortable position, simultaneously, still increased the function of carrying out notebook computer or desktop computer keyboard operation on the support. The multifunctional support can be fixed on the chair back or leg columns of the chair in a clamping seat mode, when people use the support to operate a computer, the back can be completely attached to the backrest of the chair backwards, the pressure of the body to the waist and the back and the neck is greatly reduced, and people can work in a healthier mode.

The utility model provides a technical scheme that its technical problem adopted is: the clamping seat is connected with one end of a cantilever through a ratchet wheel device, and the cantilever can rotate around the clamping seat and hover at a reasonable position of a rotating plane of the cantilever; the length of the cantilever is a telescopic structure. The other end of the cantilever is connected with a cross arm by adopting a shaft sleeve hinge structure and is provided with a locking device, when the bracket is used, the cross arm and the cantilever are in a vertical state, and the locking device is locked, so that the position relation between the cantilever and the cross arm is stable; when the bracket is not used, the locking device is opened, and the cross arm and the cantilever can be folded into a straight shape. The other end close to the cross arm is sleeved with a supporting plate with a locking device, the supporting plate can move radially and rotate axially along the cross arm by adjusting the locking device, and books, mobile phones, tablet computers, notebook computers and desktop computer keyboards can be placed on the supporting plate. The position between the supporting plate and a user can be adjusted in all directions by the telescopic suspension wall, the rotation around the clamping seat and the axial rotation and radial movement of the supporting plate.

The utility model discloses further setting up to: two wire tying columns are arranged on the back surface of the supporting plate and are longitudinally close to the upper end and the lower end, and are respectively connected with two ends of a wire rope which bypasses the front surface of the supporting plate.

The utility model discloses further setting up to: a wire tying column is arranged near one transverse side of the back of the supporting plate, a wire rope is wound on the wire tying column, the other end of the wire rope is tied to the hook, after a user reads books and turns pages, the wire rope bypasses the pages of the books, the hook is hung on the other transverse side of the supporting plate, the wire rope compresses the pages, and the pages are guaranteed to be attached to the supporting plate. The length of the thread rope can be adjusted by winding the thread tying column for different numbers of turns.

The utility model discloses further setting up to: the supporting plate is provided with two long holes for installing a special clamp of the mobile phone or the tablet computer so as to fix the mobile phone or the tablet computer on the supporting plate.

The utility model discloses further setting up to: the bottom of the supporting plate is provided with a flange which is used for preventing the book, the notebook computer and the desktop computer keyboard from sliding downwards.

The utility model has the advantages that: 1. more functions are added; 2. the more reasonable structural design enables the chair to be widely used in office places, and people can work by leaning against the chair back, so that the people can work and study without bending over the desk; 3. can effectively prevent the occurrence of cervical spondylosis and lumbar spondylosis; 4. more importantly, the support arranged on the bed head greatly facilitates reading before sleep and can cultivate the wind and the smell of reading before sleep of the whole population.
