Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of desk that anti-books are fallen, and can prevent from being then turned on cover board
When books squeezed out.
The technical solution adopted by the present invention to solve the technical problems is: the desk that anti-books are fallen, including cabinet, setting
The support leg of the bottom of box is arranged in desktop and cover board on cabinet, and the desktop is fixed on the cabinet, the cover board
One end of one end and the desktop is rotatablely connected by hinge, and the hinge includes a shaft and two panels turnover panel, described in two panels
One end of turnover panel and the shaft are rotatablely connected, and are provided with one piece of rotor plate, the two sides of the rotor plate above the desktop
It is provided with sliding slot, the two sides of the desktop are provided with first connecting rod and second connecting rod, one end rotation connection of the first connecting rod
On the desktop, the other end of the first connecting rod is rotatably connected on the rotor plate, and described second connecting rod one end is fixed
On the desktop, the other end of the second connecting rod is inserted into the sliding slot, and when normal condition, the rotor plate is in gravity
Lower cover is acted on the desktop, when opening the cover board, the cover board pushes one end of the rotor plate, the rotor plate
The other end gradually up lifts under the action of the second connecting rod, and in the process, the second connecting rod maintains the rotor plate one
The position at end.In actual use, the books being placed on desktop originally are placed on rotor plate, and while opening cover board, rotor plate is past
Upper rotation, the books being arranged on rotor plate can be tilted towards desk direction, even if the books on cover board push on rotor plate
Books, and the books on rotor plate are compressed towards plate face, books will not be pushed away toward ground, therefore unlatching can be effectively prevented
Books are fallen when cover board.
In above-mentioned technical proposal, it is preferred that further include two sliding sleeves made of elastic material, a sliding sleeve is fixed
On the desktop, another described sliding sleeve is fixed on the cover board, and the other end of turnover panel described in two panels is inserted into two panels respectively
In the sliding sleeve, be provided with through-hole on the turnover panel, the first screw pass through one of after the sliding sleeve and the through-hole with institute
It states desktop mutually to fix, the second screw is mutually fixed after passing through another described sliding sleeve and the through-hole with the cover board, the through-hole
Diameter be greater than first screw and the second screw head outer diameter.If finger is placed on the side that cabinet is in contact with cover board
On, then down cover clamp when, cover board agitates one end that cover board is hinged with desktop and up moves, up transport using finger as fulcrum
During dynamic, sliding sleeve is stretched, therefore biggish injury will not be caused to finger.
In above-mentioned technical proposal, it is preferred that two sliding sleeves are separately positioned on the desktop and the cover board is opposite
On two faces.
In above-mentioned technical proposal, it is preferred that the material of the sliding sleeve is rubber.
In above-mentioned technical proposal, it is preferred that first screw and second screw are the screw of same model.
The beneficial effects of the present invention are: the rotor plate is covered under gravity on the desktop when normal condition,
When opening the cover board, the cover board pushes one end of the rotor plate, and the other end of the rotor plate is in the second connecting rod
Under the action of, it gradually up lifts, in the process, the second connecting rod maintains the position of described rotor plate one end.In actual use,
Originally the books being placed on desktop are placed on rotor plate, and while opening cover board, rotor plate is up rotated, and are arranged on rotor plate
Books can be tilted towards desk direction, even if books on cover board push the books on rotor plate, and will be on rotor plate
Books are compressed towards plate face, will not fall books toward books when pushing away on the ground, therefore unlatching cover board can be effectively prevented.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is schematic diagram of the invention.
Fig. 2 is the connection schematic diagram of hinge of the present invention Yu desktop and cover board.
Fig. 3 is the schematic diagram of cover board open state of the present invention.
Specific embodiment
Referring to Fig. 1-3, the desk that anti-books are fallen, including cabinet 1, the desktop being arranged on cabinet 12 and cover board 3, setting
Support leg 11 in 1 bottom of cabinet.
The desktop 2 is fixed on the cabinet 1, and described 3 one end of cover board and one end of the desktop 2 pass through 4 turns of hinge
Dynamic connection.
The hinge 4 includes a shaft 41 and two panels turnover panel 42,43, one end of turnover panel 42,43 described in two panels with it is described
Shaft 41 is rotatablely connected, and further includes two sliding sleeve 44,45 made of elastic material, and in the present embodiment, sliding sleeve 44,45 is by rubber
It is made.Two sliding sleeves 44,45 are separately positioned on the desktop 2 and opposite two faces of the cover board 3.One cunning
Set 44 is fixed on the desktop 2, another described sliding sleeve 45 is fixed on the cover board 45, and the other end of the turnover panel 42 is inserted
Enter in the sliding sleeve 44, the other end of the turnover panel 43 is inserted into the sliding sleeve 45, is provided with through-hole on the turnover panel 42,43
4a, 4b, 4a is fixed with 2 phase of desktop after the first screw 51 passes through one of the sliding sleeve 44 and the through-hole, the second spiral shell
Nail 52 is fixed after passing through another described sliding sleeve 45 and the through-hole 4b with 3 phase of cover board, first screw and described the
Two screws are the screw of same model.The diameter of described through-hole 4a, 4b are greater than first screw 51 and second screw 52
Head outer diameter.If finger is placed on the side that cabinet is in contact with cover board, then down cover clamp when, cover board using finger as fulcrum,
It agitates one end that cover board is hinged with desktop up to move, during the upward movement, sliding sleeve is stretched, therefore will not make finger
