Summary of the invention
The utility model provides a kind of hand-held board, and this hand-held board is convenient to installation and removal, and easily clean, outward appearance is beautiful, fastness is good, effectively improves writer's surrounding environment, improves viewing board angular field of view and definition.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hand-held board, comprise the substrate with black upper surface, write pad pasting, upper side frame and lower frame, on the upper surface that described upper side frame and lower frame are installed on substrate respectively and lower surface, this upper side frame and lower frame side is in opposite directions respectively arranged with upper hopper chute, gliding groove, this upper hopper chute, top sheave is embedded with respectively in gliding groove, lower sheave, one litter one end is arranged on top sheave, this litter other end is arranged on lower sheave, the described pad pasting that writes is made up of polyester film and the micropore adhesive layer being coated on polyester film surface, micropore adhesive layer is positioned at polyester film and substrate surface in opposite directions, described polyester film two ends are respectively arranged with first, second bending part, described litter is positioned at polyester film or first, below second bending part, the lower surface that described polyester film contacts with micropore adhesive layer is evenly distributed with several lug bosses.
The technical scheme improved further in technique scheme is as follows:
1, in such scheme, the thickness of described polyester film is 75 μm ~ 200 μm.
2, in such scheme, first, second bending part described and substrate angle are 10 ° ~ 30 °.
3, in such scheme, the lower surface roughness of described polyester film is the surface of 1.0 μm ~ 3.0 μm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model hand-held board, its structure is simple, and reasonable in design, production cost is low, be convenient to installation and removal, easy scouring, outward appearance is beautiful, and fastness is good, automatically the word that writer writes on clipboard can be carried out auto-erasing, effectively improve writer's surrounding environment, and both greatly reduce use cost, also reduce pollution; Secondly, its polyester film two ends are respectively arranged with first, second bending part, and described litter is positioned at below polyester film or first, second bending part, and time easy to use, polyester film is peeled off by operator fast, improve efficiency of erasing; Again, the lower surface that its polyester film contacts with micropore adhesive layer is evenly distributed with several lug bosses, thus form at this upper surface the surface that roughness is 1.0 μm ~ 3.0 μm, both also can improve the sense of touch that the pad pasting that writes is write, also greatly improve viewing board angular field of view and definition.
