Abstract
The utility model relates to an adjustable book plate, belonging to the appurtenance field for typewriting use. The utility model includes a soleplate, and an elastic press plate whose one end can contact with but is not connected with the soleplate. The other end of the elastic press plate is fixedly connected with a pedestal which can slide along a pole setting, and the lower end of the pole setting is fixed on the soleplate. The utility model has the advantages of simple structure and low cost, and is convenient and practical.
Description
Technical field
The utility model relates to a kind of aid of the usefulness of typewriting, and relates in particular to a kind of adjustable pressing board.
Background technology
Along with development of science and technology, computer application is in daily life popularized gradually, computer office also becomes inevitable, yet import on the paper spare in the literal people, see the input of paper spare limit owing to need the limit, owing to there is not specific purpose tool, page turning and paper location are very inconvenient, have influenced people's office speed.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and a kind of technical scheme of adjustable pressing board of special use simple in structure, convenient and practical, with low cost is provided.
The utility model is realized by following technical measures: it comprises base plate, and an end can contact but unconnected spring bearer plate with base plate, the other end of spring bearer plate with can be connected along the elevating bracket that vertical rod is slided, the vertical rod lower end is fixed on the base plate.Utilize spring bearer plate that paper is fixed, because the thickness difference of paper spares such as book, can be by moving up and down the distance between elevating bracket adjusting spring bearer plate and the base plate, elevating bracket falls to driving spring bearer plate by deadweight and compresses the paper location.
For spring bearer plate is better located, the utility model has been done further improvement, is provided with lifting-positioning device in the elevating bracket.Be combined with lifting-positioning device, can better overcome the bounce of paper.Lifting-positioning device specifically can comprise two friction plates that are wrapped on the vertical rod corresponding surface, between two friction plates the slit is arranged, two corresponding spring are arranged, the two ends of spring are connected with friction plate and elevating bracket are inner respectively, pass the elevating bracket housing and be provided with and two wedge shape blocks that the slit is corresponding, insert in the friction plate at the tip of wedge shape block.Connect between its various parts and adopt routine techniques, when the wedge shape block outer end pinned in the hull outside of elevating bracket, separately and between the vertical rod almost break away to both sides respectively under the effect of two friction plates in external force, elevating bracket can move along vertical rod, when unclamping under the elastic force of spring, friction plate compresses vertical rod, the elevating bracket location can not move up and down.
Base of the present utility model specifically can adopt the transverse slat that is connected with riser, and with the swash plate that transverse slat is connected, swash plate becomes 15 degree angles with horizontal plane.Can be convenient for people to like this watch, shape and structure are not limited to this certainly.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the structural representation enlarged drawing of the interior lifting-positioning device of elevating bracket in the utility model specific embodiment.
Wherein, 1. elevating bracket, 2. spring bearer plate, 3. vertical rod, 4. transverse slat, 5. swash plate, 6. riser, 7. wedge shape block, 8. friction plate, 9. spring, 10. base plate, 11. slits.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
It comprises base plate, and an end can contact but unconnected spring bearer plate 2 with base plate 10, the other end of spring bearer plate 2 with can be connected along the elevating bracket 1 that vertical rod 3 is slided, when elevating bracket 1 was positioned at extreme lower position, spring bearer plate 2 can compress base plate 10; Vertical rod 3 lower ends are fixed on the base plate 10 by being threaded.Be provided with lifting-positioning device in the elevating bracket 1, lifting-positioning device comprises two friction plates 8 that are wrapped on vertical rod 3 corresponding surfaces, between two friction plates 8 slit 11 is arranged, two corresponding spring 9 are arranged, the two ends of spring 9 respectively with the middle part of friction plate 8 and 1 inner corresponding connection of elevating bracket, spring is in compressive state, passes elevating bracket 1 housing and is provided with the wedge shape block 7 corresponding with two slits 11, the front end of wedge shape block 7 is the triangular taper, in the slit 11 that two friction plates of its most advanced and sophisticated insertion 8 form.Base plate 10 comprises riser 6, and with the transverse slat 4 that riser 6 is connected, with the swash plate 5 that transverse slat 4 is connected, swash plate 5 becomes 15 degree angles with horizontal plane.The outer shape of elevating bracket of the present utility model adopts rectangular-shaped but is not limited thereto.
