Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1 to 7, the dual-purpose drawing table for the bed and the ground in the dormitory for students comprises a table leg structure at the lower part and a table top structure at the upper part, wherein a height adjusting structure is arranged between the table leg structure and the table top structure.
The table leg structure comprises a shelf 11 and a bottom plate 12, the shelf 11 is fixed on the bottom plate 12, a plurality of upper and lower layer plates (as shown in figure 1) are arranged in the shelf 11, and a read book can be directly placed on the layer plates, so that the read book is not larger than the read book which is placed on a table top, and a larger space is left for the table top. And the cabinet 11 is only fixed on the left half of the bottom plate 12, because the desktop structure will involve an extended drawing structure, and the right half of the bottom plate 12 plays a balance role to prevent the desk from tipping. When opening the book on the bed, the right half part is extended under the bed.
Further, the base 12 is placed on the floor with the extension of the table top structure extending into the bed. And the lower surface of the bottom plate 12 is provided with lockable rollers. When a rest is needed, the desk is pushed away, and the situation of bruising or turning over can not be worried.
In the scheme, the desktop structure comprises a desk plate A1, a drawing frame 2 and a desk plate B3, wherein an inner cavity is formed in the desk plate A1, the right side of the inner cavity penetrates through the desk plate A1, and the drawing frame 2 capable of being drawn is arranged in the inner cavity. This configuration is intended to allow the table top to be extended. But the height of the extended horizontal plane is not consistent with the height of the original desktop.
In order to ensure that the horizontal height is always kept, furthermore, an upper and a lower two-stage buckling platforms 201 are arranged on the inner wall of the drawing frame 2, and corresponding buckling grooves are formed on the side surface of the desk board B3. When the fastening groove of the desk board B3 is installed in cooperation with the fastening platform 201 at the lower stage, the front side faces downwards and the back side faces upwards, and the horizontal plane of the back side is lower than the horizontal plane of the upper end face of the drawing frame 2; when the fastening groove of the desk board B3 is fitted with the fastening platform 201 on the upper stage, the front surface of the desk board B3 faces upward and the back surface faces downward, and the horizontal plane of the front surface is the same plane as the horizontal plane of the desk board a 1.
The height adjusting structure of the table has multiple designs, the most common design is that the table legs are directly designed into multiple sections which are connected through adjusting screws, but the whole table top needs to be lifted up and then needs to be stooped down to be accurately aligned to achieve the height adjusting structure. The other is to use a crossed structure for adjustment, then use an auxiliary piece, wherein the auxiliary piece is provided with a special-shaped hole, but when the auxiliary piece is clamped in the special-shaped hole each time, the auxiliary piece is initially placed in the special-shaped hole and is not in the correct position, and the auxiliary piece is gradually corrected in the special-shaped hole under the action of pressure. The correction of the position of the shaped holes under pressure causes a certain vibration, which is possible with some seat adjustments, but which, in the case of tables, causes the table top to be less stable.
For this reason, this scheme designs the altitude mixture control structure as: including two pairs of articulated units, two pairs of articulated units set up respectively in front and back both sides position, and articulated unit includes post A4 and post B5, and post A4 and post B5 middle part are articulated and upper and lower both ends articulate respectively on articulated seat 13, and articulated seat 13 and table A1 and table leg structure slide and set up. The most central design is as follows: the hinge unit further comprises an adjusting piece 6, the adjusting piece 6 is long-strip-shaped, a waist-shaped long hole is formed in the adjusting piece 6, a plurality of semicircular notches 601 are formed in the upper edge of the waist-shaped long hole at intervals, one end of the adjusting piece 6 is hinged to the outer side of the column A4, a transverse pin 7 is fixed to the outer side of the column B5, and the semicircular notches 601 of the adjusting piece 6 are clamped on the transverse pin 7; the outer end of the transverse pin 7 is sleeved with a sliding cover 8, the inner end face of the sliding cover 8 is provided with a plurality of bolts 801, the circumferential direction of the semicircular notch 601 on the adjusting piece 6 is provided with a corresponding insertion hole 602, and the bolts 801 are inserted into the insertion holes 602 when the sliding cover 8 slides towards the inner end of the transverse pin 7.
The design has the advantages that the semicircular notches 601 are matched with the transverse pin 7, and the positions of the transverse pin 7 and the semicircular notches 601 cannot be changed, namely, vibration cannot occur under the action of pressure, so that the stability of the desktop is ensured; meanwhile, the plug 801 of the sliding cover 8 is inserted into the jack 602, and the transverse pin 7 is placed to jump out of the semicircular notch 601. And the design is convenient to adjust: when the adjustment is needed, the sliding cover 8 is pulled out, force is applied to the vertical direction slightly along the horizontal direction, the adjustment can be carried out, the adjustment can be realized even if the user sits on the bed, and the adjustment is more labor-saving compared with the adjustment in which a large amount of force is applied to the vertical direction.
In the height adjustment, the table a1 must not be moved to the right and left excessively when a force is applied in the right and left direction. For this purpose, the hinged seat 13 at the right upper end of the column A4 is fixed on the lower surface of the desk board A1, and the hinged seat 13 at the right lower end of the column B5 is fixed on the structure of the desk leg; the hinged seat 13 at the left lower end of the column A4 is arranged in a sliding way with the table leg structure, and the hinged seat 13 at the left upper end of the column B5 is arranged on the lower surface of the table A1 in a sliding way.
The hinge base 13 is slidably disposed such that a sliding groove is disposed in a component connected to the hinge base, the bottom of the hinge base 12 is engaged with the sliding groove in a tenon-shaped structure, and a ball is further disposed between the tenon-shaped head and the sliding groove (as shown in fig. 7).
In this embodiment, the two sides of the upper and lower surfaces of the drawing frame 2 are both provided with rolling grooves 202, the inner cavity is provided with corresponding rollers 101, and the lower part of the desk board a1 is provided with a thread locking knob 9.
In order to realize the angle adjustment, the back of the desk board B3 is hinged with the upper edge of the rectangular frame 10, and the inner bottom of the drawing frame 2 is provided with a plurality of parallel clamping grooves 203. In adjustment, the lower edge of the rectangular frame 10 abuts against the slot 203 and one side of the desk board B3 abuts against the buckle table 201 when the rectangular frame is unfolded. The angle is adjusted according to the angle of the person lying on the bed, so that the sight line of the eyes is perpendicular to the desk board B3.
