Detailed Description

In one embodiment, referring to fig. 1-11 of the specification, a portable soft-edge angle-adjusting magnetic writing board with a U-shaped bracket comprises a whiteboard body and a U-shaped bracket, white iron sheets are bonded on the front and back surfaces of the whiteboard body, a threaded hole is formed in the middle of the side surface of the whiteboard body, the threaded holes on the two sides are symmetrically arranged, through holes are formed in the two ends of a side lever of the U-shaped bracket, the two through holes respectively correspond to the two threaded holes, a manual screw is inserted between the through holes and the threaded hole, the connection between the U-shaped bracket and the whiteboard body is locked or loosened by rotating the manual screw, a soft anti-slip sleeve is wrapped outside the U-shaped bracket, a soft wrapping edge is arranged on the edge of the writing board body, the soft anti-slip sleeve and the soft wrapping material are made of rubber, and other soft materials with good anti-slip effect can be selected.

The length of the side rod of the U-shaped support is larger than one half of the length of the white board body, and the cross rod at the lower end of the U-shaped support after being folded can be used as a handle, so that the carrying is convenient.

The both sides of a blank body terminal surface all are fixed with the supporting shoe through the screw, and the supporting shoe of lower extreme supports at the desktop after the clipboard props up, avoids wearing and tearing the bordure of lower part, if the material of desktop is comparatively smooth, can get rid of the supporting shoe, and the bordure of lower part is direct and the desktop contact, increase frictional force, improvement stability.

The junction of U type support and blank body both sides all is equipped with anti-skidding subassembly, anti-skidding subassembly include fixed tooth plate of fixed connection in the middle of the white board body side, the movable tooth plate of fixed suit at U type support both sides rod end portion, be equipped with annular tooth first in the middle of fixed tooth plate's the lateral surface, movable tooth plate's medial surface is equipped with the annular tooth second with annular tooth first meshing, two pinion racks increase the frictional force between U type support and the white board body side through the annular tooth meshing, the not good problem of fastening effect that only tightens up through manual screw has been solved, write the problem that the blank collapses in the in-process is difficult for appearing, the centre of annular tooth first and annular tooth second all is equipped with the round hole, manual screw passes from two round holes.

The middle of the two sides of the fixed toothed plate is symmetrically provided with clamping plates extending out of the inner side surfaces of the fixed toothed plate, the two clamping plates are respectively tightly pressed on the two sides of the soft edge covering, the firmness of connection between the fixed toothed plate and the white board body is improved, and the firmness of connection between the edge covering and the white board body is also improved.

Be equipped with the inner ring cover in the annular tooth first of fixed tooth plate, inner ring cover and the coaxial setting of round hole, be equipped with outer ring cover in the annular tooth second of adjustable tooth plate, outer ring cover and the coaxial setting of round hole, outer ring cover is gone into and is formed the revolute pair in inner ring cover, and this rotation connection structure is used for the centering between annular tooth first and the annular tooth second, and the dislocation between the two pinion racks when avoiding adjusting the support, the internal diameter of outer ring cover and inner ring cover all is greater than the diameter of round hole.

The using method of the utility model is as follows: when the anti-skid white board is used, the manual screw is loosened, the inner toothed plate and the outer toothed plate of the anti-skid assembly are separated, the meshed annular tooth A and the annular tooth B are separated, the U-shaped support is adjusted to a proper supporting angle, then the manual screw is tightened, the inner toothed plate and the outer toothed plate are pressed tightly, the annular tooth A and the annular tooth B are meshed again, the friction force between the U-shaped support and the side face of the white board body is increased due to the meshing of the two annular teeth, and the white board is not prone to collapse in the writing process; the soft antiskid cover of U type support outer parcel is used for increasing frictional force, and the pressure of applying when avoiding writing leads to the clipboard at the gliding problem of desktop, has improved the stability of writing, and the soft of blank body is bordured and can not only be played the guard action, prevents that its corner from colliding with desktop, human body and causing the damage, also can play the antiskid effect simultaneously, and this clipboard structure is small and exquisite, functional strong, portable has wide market prospect.
