Detailed Description

The present invention will be further explained with reference to the drawings (hereinafter, the right side direction of fig. 1 will be referred to as the front direction).

As shown in fig. 1 and 2, the folding structure of the desktop for learning desk comprises a desktop board 1 and a hole portion, wherein the desktop board 1 is fixedly installed at the top of the hole portion.

The position hole part comprises an upper connecting vertical plate 3, a lower connecting vertical plate 4, a vertical plate connecting rod 5 and a position hole bottom plate 6; the upper connecting vertical plate 3, the lower connecting vertical plate 4 and the vertical plate connecting rod 5 are arranged symmetrically left and right relative to the desktop plate 1, the upper connecting vertical plate 3 and the lower connecting vertical plate 4 are arranged in parallel, the front parts of the upper connecting vertical plate 3 and the lower connecting vertical plate 4 are hinged and installed on the upper part of a learning desk supporting leg 7, two ends of the vertical plate connecting rod 5 are respectively hinged and connected to the rear parts of the upper connecting vertical plate 3 and the lower connecting vertical plate 4, and the learning desk supporting leg 7, the upper connecting vertical plate 3, the lower connecting vertical plate 4 and the vertical plate connecting rod 5 jointly form a parallelogram; the desktop plate 1 is horizontally erected and fixedly arranged at the tops of the two upper connecting vertical plates 3; the position hole bottom plate 6 is horizontally erected and installed between the two lower connecting vertical plates 4, and a position hole space is defined by the bottom plane of the desktop plate 1, the inner surfaces of the upper connecting vertical plate 3 and the lower connecting vertical plate 4 and the upper plane of the position hole bottom plate 6; an angle positioning structure capable of performing angle positioning within the range of-90 degrees to 0 degrees is further arranged at the front hinged position of the upper connecting vertical plate 3 or the front hinged position of the lower connecting vertical plate 4.

When the study table is unfolded for normal use, the angle positioning structure on the front hinged position of the upper connecting vertical plate 3 or the front hinged position of the lower connecting vertical plate 4 can perform angle positioning of a set angle within a range of-90 degrees to 0 degrees, so that the table top plate 1 is designed into an inclined table top with an adjustable angle, when the table top plate 1 is in a horizontal state, articles can be placed in the space of the position hole, under the condition that the rear end of the position hole bottom plate 6 is provided with a bending part which is perpendicular to the position hole bottom plate 6 and is bent upwards, and books can be placed through the bending part of the position hole bottom plate 6 when the table top plate 1 is in an inclined state. When needing to fold to accomodate, as shown in figure 3, control angle location structure make desktop board 1 turn over a book to the back below, until desktop board 1 be vertical state can, this moment position hole space also compresses completely foldingly, as shown in figure 4, the upset beta structure of cooperation study table supporting leg 7 bottom can realize that the whole folding back of study table is the riser structure, lean on the wall can.

In order to block the front end of the hole space and prevent the articles placed in the hole space from falling from the front end of the hole space when the learning table is in a normal use state after being unfolded, as a further improvement scheme of the invention, the front end of the table top plate 1 is also hinged with a front sealing plate 2, and the area size of the front sealing plate 2 is matched with the area size of the front end surface of the hole space. The front closing plate 2 can also prevent dust from entering the hole part in the vertical state when the folding state is carried out.

In order to further realize the effect of blocking the space of the position hole, as a further improvement scheme of the invention, the front end surface of the hole bottom plate 6 on the rear end surface of the front sealing plate 2 is also provided with magnetic strips or magnetic blocks which can be mutually adsorbed and connected in a matching way.

In order to prevent the front closing plate 2 from occupying extra space due to the forward extending structure formed after the position hole part is folded, as a further improvement of the invention, the front closing plate 2 is a curtain-shaped structure formed by a plurality of plates which are hinged and connected up and down in sequence. The front closing plate 2 of the curtain-shaped structure can form a covering structure in a self-adaptive mode according to the shape of the folded end part after the position hole part is folded.

In order to increase the supporting strength, as a further improvement scheme of the invention, the support of the lower connecting vertical plate 4 and the supporting leg 7 of the learning table is also provided with a detachable inclined supporting rod 8 with a position hole.

In order to realize the purpose of blocking the left side surface and the right side surface of the hole space, as a further improvement scheme of the invention, a plurality of vertical plate connecting rods 5 are arranged at intervals along the front-back direction.

As one embodiment of the present invention, the angular positioning structure is a ratchet and pawl structure.

This study table desktop beta structure adopts parallelogram beta structure, can realize desktop and the holistic folding in position hole, and then solves the space and occupy big problem.
