The specific embodiment:
See Fig. 1,2, present embodiment one mainly is made up of baffle 1, supporter 2 and fixture.Baffle 1 can be regulated and be installed in supporter 2 tops, and supporter 2 bottoms are fixed on desk 4 edges by fixture.Particularly, baffle 1 is fixed on supporter 2 tops by first bolt 12: offer countersunk head groove 13 on the baffle 1, offer several installations that are used to regulate itself and supporter 2 assembling height in this countersunk head groove 13 with counterbores 11; Offering some through holes 21, the first bolts 12 corresponding with counterbore 11 on the baffle 1 on the described supporter 2 passes counterbore 11 and with through hole 21 baffle 1 is fixedlyed connected with supporter 2.
Fixture is a U type bearing 6 that is fixed on supporter 2 lower ends in the present embodiment, and desk 4 edges insert in the U type bearing mouth 61 of U type bearing 6, and by the 3rd bolt 23 or screw 5 U type bearing 6 and desk is fixed.
See Fig. 3, fixture comprises in the present embodiment two: be opened in the otch 24 that supporter 2 lower side are used to place nuts and washers, second bolt 22 and vertically offer in otch 24 and be used for the bolt hole 25 that second bolt 22 passes, above-mentioned nuts and washers cooperate with second bolt 22 that passes desk 4 supporter 2 are fixed on the desk 4.
See Fig. 4, the fixture in the present embodiment three is included as screw 5, and screw 5 is screwed into desk 4 and is positioned over desk 4 upper support bodies 2 lower ends and fixedlys connected.
See Fig. 5, fixture comprises in the present embodiment four: screw 5 and anchor clamps 3, and anchor clamps 3 are fixed on supporter 2 lower surfaces by screw 5; Anchor clamps 3 comprise clamping part and are installed in fastening bolt 32 on the clamping part, and the feeding by fastening bolt 32 is fixed on anchor clamps 3 on the desk 4.
See Fig. 6, fixture is anchor clamps 3 in the present embodiment five, and anchor clamps 3 comprise clamping part and be installed in fastening bolt 32 on the clamping part, and the feeding by fastening bolt 32 is fixed on anchor clamps 3 on the desk 4; Supporter 2 lower ends are one-body molded a U type bearing 6, and U type bearing 6 is fixedlyed connected with anchor clamps 3.For present embodiment, supporter 2 and U type bearing 6 and anchor clamps 3 use technologies such as injection moulding or the bending of use metal material to unify, and screw bolt, and overall fixed on the table, the Ling Li corner needs edging or abate, in case injure the user.
For the above-mentioned fixture of explaining, can adopt alternate manner, for example: supporter 2 and U type bearing 6 also available technologies unify, material can be with timber (for example using mold pressing plank technology), plastic rubber material or metal material etc., U type bearing 6 uses several wood screws fixing on the table (for example for the existing study table of family), or only be fastened on the steadiness that increases its structure on the table study table of desk that uses in the classroom or new production (for example for) with bolt, or mix with several wood screws and bolt and to be connected and fixed on the table, U type bearing 6 connectors and joint face are not advisable not protrude desktop as far as possible.
For the technical scheme that adopts U type bearing 6, because the one side of close human body has the distance of a fist approximately from the table edge, this distance can be regulated, and promptly increases with height.Why adopt U type bearing 6, this is because it has a U type bearing mouth 61, opens its bottom of large paper edition books or homework book and can move in the U type bearing mouth 61, can far not feel to write uncomfortable from large paper edition homework book top because of eyes like this.For existing desk in the classroom, can hole, countersunk head uses hexagon socket head cap screw to reinforce U type bearing 6, if desktop will paste a facing plate when producing table, the outer-hexagonal bolt head can be inserted under the facing plate, though the complicated point of technology, the desktop outward appearance seems more perfect.
During use; owing on desk 4, the utility model has been installed; for the student that need lie prostrate the table rest noon; owing to being installed on the desk, the utility model produces certain influence; the utility model also provides following scheme: see Fig. 7; in the present embodiment six, offer shifting chute 14, the first bolts 12 on the baffle 1 and pass shifting chute 14 and fixedly connected with supporter 2.Can adjust the horizontal level of baffle 1 by shifting chute 14.
In addition, also can adopt following structure, see Fig. 8, in the present embodiment seven, baffle 1 comprises stator 16 and the pleated sheet 17 that is articulated by loose-leaf 7, and wherein stator 16 is connected with supporter 2; Between stator 16 and pleated sheet 17 positioner 8 is set, this positioner comprises: be installed in the location shank 81 on the stator 16 and be fixed on the pleated sheet 17 and the locating hole 82,83 that cooperates with location shank 81.Present embodiment is divided into two with baffle 1, and connects by loose-leaf 7 hinges.Like this, pleated sheet 17 can rotate, and when normally using location hook 81 is inserted in the locating hole 83, after needs are folded up baffle 1, and pleated sheet 17 is turned over certain angle, location shank 81 is inserted locating hole 82 interior getting final product.
