Description

A kind of multifunction railway learning desk

Technical field

The present invention relates to furniture, the desk that particularly a kind of student uses.

Background technology

The desktop of existing student's desk generally can not spur front and back, even if desktop can spur, the gradient of desktop can not be regulated.Chinese patent disclosed a kind of " multifunctional rail desk " (200510032265.0), not only desktop can move forward and backward, and can be with the gradient of the mobile adjusting desktop of desktop.But also there is following defective in this desk: the one, and bookrest fixedly mounts on the table, can not be according to student's the eyesight and the size adjustment sighting distance of bookish character and graphic.Simultaneously, it is big that bookrest takies the desktop area, and desktop was too heavy when the plane was regulated on high inclined-plane, used not very convenient; The 2nd, writing case is suspended on both sides, support force a little less than, adopt the track pulling to increase production cost and installation difficulty; The 3rd, when desktop was moved high gradient to, because of desktop gravity desktop is difficult to latched position, desktop moved forward easily; The 4th, desktop is connected with fishplate bar, if desktop is special-shaped, fishplate bar production difficulty is big.And fishplate bar and desktop must cause double-deck desktop, and the gravity increase brings uses inconvenience, are unfavorable for that off year, rheology was given birth to use.

Summary of the invention

The object of the present invention is to provide a kind of student to use table, but the position free adjustment of its bookrest, writing case can freely be twitched and can not be drawn out, and desktop pulling and adjusting are more flexible.

For achieving the above object, embodiment of the present invention are: a kind of multifunction railway learning desk, has active desktop, bookrest, writing case, the front upper place of active desktop is provided with the book platform, it is characterized in that, the rear end of active desktop is movably arranged on two pulling tracks that are arranged at a wall, active desktop can be stirred, article two, the leading portion of pulling track connects with fishplate bar, the leading portion of active desktop places on the fishplate bar, at the front end dual-side of fishplate bar card article is installed, and the latch of card article can move on the pulling track, both sides table wall under the book platform is provided with base plate, be provided with riser between the inboard of base plate and the book platform table top, writing case is sleeved on by base plate, the space that riser and book platform table top constitute, two fast risers are symmetrically installed with the pulling track, be provided with connecting plate between the pulling track, bookrest is installed on the connecting plate.

In the middle of the described fishplate bar or the back side of active desktop front end is movably installed with the gripper shoe that can erect and set level, in order to regulate the gradient of active desktop.

Table wall above the described pulling track is provided with a plurality of latches that can move left and right, moves one of them latch and blocks latch and slide, and desktop length is pulled out in control, and the latch of mobile latch front can lock desktop.

Active desktop of the present invention directly connects in the pulling track, saved original connecting plate, thereby alleviated the weight of desktop, bookrest is installed between two writing cases, do not contact position that therefore can the free adjustment bookrest and do not influence moving of active desktop with active desktop.Writing case spurs by chute, saves cost, and pulling freely.The pulley locking device is set on the table wall, and fixedly the position of active desktop keeps active desktop can not be moved in this position.The present invention is with respect to existing similar desk, uses conveniently, and cost of manufacture is lower.
