Detailed Description

The utility model is further described with reference to the drawings, and examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

The specific embodiment adopted by the utility model is as follows:

the utility model discloses an embodiment of a technical scheme of a splicing-free portable folding writing board, and figures 1 and 2 are schematic structural diagrams of the splicing-free portable folding writing board in an unfolded state, and the splicing-free portable folding writing board mainly comprises a paper clip 2, a clamping plate 1 provided with two sliding grooves 3 and a supporting strip 4 which is arranged in the sliding grooves 3 and can slide in the sliding grooves 3. The splint 1 is made of 3 mm thick polypropylene plates 328 and 226 mm long and wide, respectively, because polypropylene is also called creased glue, and can be folded for many times without being easily broken. Two regular triangle folding guide grooves 7 with the depth of 2.5 mm are arranged on the splint 1 at a position 1.5 mm away from the transverse center line, so that the splint 1 can be conveniently folded. The clip 2 may be snapped into either the first clip slot 5 or the second clip slot 6. 4 circular grooves with the diameter of 10 millimeters and the depth of 0.5 millimeter are formed in the back surface of the splint 1 close to four corners, a pair of Velcro tapes are pasted in the circular grooves corresponding to the long edges, and after the splint 1 is folded, the Velcro tapes can be adhered together to prevent the splint 1 from opening. The back of the splint 1 is provided with two sliding chutes 3, and a supporting strip 4 processed by stainless steel is arranged in the middle; fig. 3 discloses a connecting structure of a supporting strip 4 and a chute 3, wherein the cross sections of the supporting strip 4 and the chute 3 are both in a T shape, a gap is reserved between the supporting strip 4 and the chute 3, two semicircular bulges are arranged on the supporting strip 4, and two pairs of semicircular grooves with similar shapes are arranged at corresponding positions of the chute 3; and the maximum distance of the two semicircular bulges is slightly larger than the distance of the corresponding straight groove of the sliding groove 3 and smaller than the maximum distance size of the corresponding semicircular groove, and when the supporting bar 4 slides to the corresponding position in the sliding groove 3, the supporting bar can be relatively fixed at the position. Fig. 4 is a schematic view showing a state that the paper clip 2 is mounted in the first paper clip slot 5, and the board clip is horizontal and suitable for writing on the long side of paper; fig. 5 is a schematic view showing a state that the paper clip 2 is installed in the second paper clip slot 6, and the board clip is vertical at the moment and is suitable for writing on the short edge of paper. Although the splint 1 in the technical scheme can be folded and unfolded, the splint 1 is a whole without a connecting seam, and the continuity of strokes cannot be influenced during writing; simple structure, small size after folding and convenient carrying.

Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are illustrative and not restrictive, and that any obvious modifications, substitutions or alterations can be made by those skilled in the art without departing from the spirit of the present invention.
