Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1, the writing chair includes a chair body 1 and a writing board 2 attached to the right side of the chair body, wherein:

the chair main body 1 can adopt a foldable chair structure, and comprises a chair seat 11, a chair back 12 and chair legs, wherein the chair seat 11 and the chair back 12 can adopt blow-molded plates with hollow structures, so that the whole chair is light and firm. The chair legs can be made of steel legs with good strength, a group of supporting units connected to the left side and the right side of the chair seat are mainly arranged, each supporting unit is composed of front supporting legs 13 and rear supporting legs 14 which are arranged in a herringbone mode and a connecting rod 15 connected between the front supporting legs and the rear supporting legs, two ends of the connecting rod 15 are hinged to the middle portions of the front supporting legs 13 and the upper end portions of the rear supporting legs 14 respectively, and the supporting units can be folded. The left side and the right side of the chair seat are respectively provided with a connecting plate 16 for connecting the supporting units, the front supporting feet 13 and the rear supporting feet 14 are respectively hinged with the connecting plate 16, the hinged parts of the front supporting feet 13 and the rear supporting feet 14 are both positioned below the connecting rod 15 but close to the connecting rod 15, and the hinged part of the connecting plate 16 is the part of the chair seat leaning against the rear, so that the folding of the chair seat and the chair feet is realized. And a transverse connecting rod 17 is respectively connected between the left front supporting leg 13 and the right front supporting leg 14, so that the supporting strength of the whole chair leg is ensured.

The tablet 2 is a generally L-shaped blow-molded or injection-molded plate (as shown in FIG. 2), which is foldably and rotatably connected to the chair body 1 via two front and rear support rods 18, 19 (as shown in FIG. 8). Specifically, the front and rear support rods 18 and 19 are both bent, wherein one end of the rear support rod 19 is rotatably connected to the upper end of the front support leg 13 on the right side, and the other end is fixedly connected to the bottom of the tablet 2 to support the tablet. One end of the front supporting rod 18 is rotatably connected to the front end of the right connecting plate 16, and the other end is fixedly connected to the bottom of the tablet 2 to support the tablet, so that when the seat of the chair is folded upwards, the tablet 2 can also be folded downwards, and the whole chair is folded (as shown in fig. 10).

The chair body and the tablet are not limited to the structure and shape shown in the drawings of the present embodiment and described above, and various modifications are possible.

Referring to fig. 2, 3 and 6, in order to place a pen, a mobile phone and the like, a pen placing groove 22 is formed in the tablet 2, the pen placing groove 22 can also be used for erecting the mobile phone or the tablet computer 4, the pen placing groove is a horizontally arranged strip-shaped groove, the thickness of the strip-shaped groove is matched with that of the existing mobile phone or tablet computer, the depth of the strip-shaped groove can be 13-16 mm, and the width of the strip-shaped groove is 15-17 mm. And a blocking edge 221 which faces the outer side edge is convexly arranged on the inner wall of the inner side edge of the strip-shaped groove, the bottom of the blocking edge 221 is approximately positioned at one half of the depth of the strip-shaped groove, and if the groove depth is 15mm, the bottom of the blocking edge 221 is preferably approximately 7.5mm away from the groove bottom. Thus, when the mobile phone or the tablet computer 4 is inserted and tilted forward slightly, the blocking edge 221 can block the mobile phone or the tablet computer from tilting, and the mobile phone or the tablet computer can be erected on the tablet board and has a proper forward-tilted viewing angle.

Because the strip-shaped groove has a certain depth, the pen is not easy to take out after being put in, so that the pen is convenient to take out, the middle part of the inner side edge of the strip-shaped groove can be also provided with an inwards concave notch 222 which is beneficial to fingers to take and pinch the pen, and the notch 222 can be arc-shaped or semicircular and the like. The notch 222 is preferably provided at a middle portion of the inner side, and the inner wall of the inner side is divided into left and right portions by the notch 222, and the inner walls of the left and right portions are provided with the retaining edges 221. Therefore, the pen can be taken more conveniently without influencing the function of the blocking edge.

Referring to fig. 2-5, the writing board has no structure for hanging the mineral water bottle, so that the mineral water can be hung on the writing board, which is specifically as follows: a concave circular cup receiving groove 21 is formed in the upper right corner of the tablet 2 so that a bottle or a cup can be received therein (see FIG. 9). A through hole 211 penetrating through the tablet is formed at the bottom of the cup holding groove 21, the through hole 211 is substantially in a plane 8 shape, and is provided with a left hole and a right hole which are connected and communicated, and the transition part of the left hole and the right hole is in a necking shape. Wherein a sheet-shaped annular flange 214 is arranged on the inner wall of the right hole 213, the caliber of the right hole 213 is smaller than that of the left hole 212 by the annular flange 214, so that the left hole 212 is an insertion hole for the upper part of the mineral water bottle to be inserted upwards from the bottom of the through hole, and the right hole 213 is a limit hole for the ring-shaped lug on the neck of the mineral water bottle to be hung.

The annular flange 214 on the inner wall of the right hole 213 and the bottom of the cup placing groove 21 form a step 215, the height of the step is slightly larger than the thickness of the annular lug 31 on the neck of the beverage bottle, and the height of the step 215 plus the depth of the cup placing groove 21 is slightly larger than the height from the bottom of the annular lug 31 to the top of the bottle cap 32, so that the annular lug 31 on the mineral water bottle can fall on the step 215 and be hung, and the bottle cap 32 is not higher than the cup placing groove 21 after being hung, namely is not higher than the surface of the writing board, as shown in fig. 7 and 8. According to the investigation result, the height from the bottom of the circular ring-shaped lug to the top of the bottle cap of the common mineral water pump bottle in the market is generally about 19.20mm, so that the height from the step of the right hole to the top of the cup placing groove can be selected to be 20.00-21.00 mm, and the top of the bottle cap is lower than the surface of a writing board after the bottle is hung.

Similarly, to insert the bottle 3 from below the left hole 212 and to engage the right hole 213, the left hole 212 has a larger diameter than the circular ring-shaped lug 31, and the right hole 213 has a smaller diameter than the circular ring-shaped lug 31 but larger diameter than the neck of the bottle below the circular ring-shaped lug 31. This allows the bottle to be inserted smoothly from the bottom of the left hole 212 and slid to the right hole 213 for a limited hanging. The diameter of the circular lug of the existing common mineral water bottle on the market is about 33.60mm, so the circular lug is matched with the diameter, and the calibers of the left hole and the right hole can be respectively selected between 34.50-35.50 mm and 29.00-30.00 mm in consideration of universality. And the two holes have crossed and overlapped parts, so the distance between the circle centers of the left hole and the right hole is preferably 16.00-18.00 mm, and the holes cannot be easily taken out because of too far distance and cannot be easily taken out because of too close distance. Preferably, the aperture Φ 3 of the left hole (Φ 2 is equal to Φ 3) can be designed to be 35.00mm, the aperture Φ 1 of the right hole is designed to be 29.50mm, and the distance H between the centers of the left and right holes is designed to be 17.00mm, as shown in fig. 12.

The bottle body is not limited in shape, so that the bottle is also suitable for various mineral water in a meeting and other bottled beverages with circular lugs or similar structures, can be hung and placed, and has good universality.
