Detailed description of the invention:

When embodiment of the present utility model is implemented, design agents mechanism comprises seat 1, the chair back 2, lumbar support projection 3, chair leg 4, threaded adjusting bore 5, height adjustment bolt 6, fastening support nut 7, gripper shoe 8, handle 9, parcel tray 10, sliding panel 11, spacing oscillating deck 12, catch bar 13, hinged seat 14, link bolt nut 15 and circular bubble level meter 16.Its technical scheme is: a kind of seat used for student, comprise seat 1, be arranged on the chair leg 4 in four bights below seat 1 and be arranged on the chair back 2 on rear side of seat 1, wherein, the rear and front end, lower surface of seat 1 is symmetrically arranged with cross section and is L shape and the gripper shoe 8 of opening laterally, the outside of gripper shoe 8 is hung with and can horizontally slips along gripper shoe 8 and cross section is the sliding panel 11 of L shape, the below of the sliding panel 11 of both sides is connected with parcel tray 10, and two, the left and right side panel of parcel tray 10 is respectively arranged with handle 9;

The position outside end, sliding panel 11 two ends is respectively arranged with hinged seat 14 for four bights of seat 1 lower surface, hinged seat 14 is made up of with the triangle plate body of the vertical with rectangular seat of lower end the rectangular seat of upper end, triangle plate body is parallel with the chair back 2, the wedge angle position, lower end of triangle plate body is connected with the spacing oscillating deck 12 of L shape by link bolt nut 15, the horizontal side plate of the spacing oscillating deck 12 of L shape extends to the inside from the position of link bolt nut 15, the perpendicular side plate of the spacing oscillating deck 12 of L shape extends downwards from the position of link bolt nut 15, the inner top side position of the perpendicular side plate of the front end face of parcel tray 10 and the close spacing oscillating deck 12 of rear end face is respectively arranged with catch bar 13,

The lower surface of chair leg 4 is provided with the threaded adjusting bore 5 upwards extended, the height of threaded adjusting bore 5 is 1/2 of chair leg 4 height, threaded adjusting bore 5 internal thread is connected with height adjustment bolt 6, and the below of chair leg 4 is also provided with the fastening support nut 7 be connected with the screw flight of height adjustment bolt 6;

The lumbar support projection 3 that rubber is made is provided with in the middle part of the lower end of the chair back 2 front end face;

Circular bubble level meter 16 is also provided with in the middle part of the upper surface of the chair back 2.

The rear and front end, lower surface of seat 1 is symmetrically arranged with cross section and is L shape and the gripper shoe 8 of opening laterally, and namely the upper end of the vertical plate body of L shape gripper shoe 8 is fixedly connected with the lower surface of seat 1, and the horizontal plate body of below is extended laterally by the lower end of vertical plate body.

The outside of gripper shoe 8 is hung with and can horizontally slips along gripper shoe 8 and cross section is the sliding panel 11 of L shape, the below of the sliding panel 11 of both sides is connected with parcel tray 10, two, the left and right side panel of parcel tray 10 is respectively arranged with handle 9, namely parcel tray 10 can be pulled to move to the left side of seat or right side by the handle 9 on left side or right side, thus drive sliding panel 11 in gripper shoe 8 to the left or right side slide, make gripper shoe 8 and sliding panel 11 with the use of the function realizing slideway and slide rail.

The position outside end, sliding panel 11 two ends is respectively arranged with hinged seat 14 for four bights of seat 1 lower surface, the wedge angle position, lower end of hinged seat 14 is connected with the spacing oscillating deck 12 of L shape by link bolt nut 15, namely the spacing oscillating deck 12 of L shape can swing around link bolt nut 15, but because it is L shape, after rotating 90 degree to the side that can rotate, the plate body of its level and the base of hinged seat 14 are adjacent to, thus stop spacing oscillating deck 12 to be rotated further, therefore the spacing oscillating deck 12 of L shape is 90 degree to the full swing angle of side; And be connected by link bolt nut 15 with hinged seat 14 due to the spacing oscillating deck 12 of L shape, the size in gap between the spacing oscillating deck 12 of L shape and hinged seat 14 can be regulated by link bolt nut 15, thus can, by the oscillation adjustment of spacing for L shape oscillating deck 12 to the state that could can only be swung by the promotion of catch bar 13, avoid it arbitrarily to rotate because of the reason such as self gravitation or vibrations.

The horizontal side plate of the spacing oscillating deck 12 of L shape extends to the inside from the position of link bolt nut 15, the perpendicular side plate of the spacing oscillating deck 12 of L shape extends downwards from the position of link bolt nut 15, the inner top side position of the perpendicular side plate of the front end face of parcel tray 10 and the close spacing oscillating deck 12 of rear end face is respectively arranged with catch bar 13, namely when parcel tray 10 moves to the left, two spacing oscillating decks 12 in the catch bar 13 promotion left side of parcel tray 10 left end both sides rotate 90 degree to the left, thus parcel tray 10 is stretched out from the left side of seat 1, can put into or take out school bag or other article, and when the catch bar 13 of the right-hand end of parcel tray 10 arrives the position of the spacing oscillating deck 12 in left side, because the spacing oscillating deck 12 in left side has been in the state that cannot be rotated further to the left, thus the catch bar 13 of right-hand end can be stoped, thus stop parcel tray 10 to continue to move to the left, parcel tray 10 is avoided to pull out from left side, to be donely put into or take out school bag or other article, hold left side handle 9, parcel tray 10 is promoted to the right, till the spacing oscillating deck 12 on the left of spacing oscillating deck 12 place on the left of the catch bar 13 of left end moves to also promotes rotates 90 degree of reinstatements to the right, from right side pull-out with when pushing back parcel tray 10, pull out with to push back principle identical with left side, when namely pulling out, right side catch bar 13 can promote right side spacing oscillating deck 12 rotate 90 degree to the right, and rotate the spacing oscillating deck 12 of 90 degree to the right, can, by stoping the catch bar 13 in left side from right side pull-out, parcel tray 10 be avoided to pull out from right side again, when pushing back, the spacing oscillating deck 12 that the catch bar 13 on right side can promote again right side rotates 90 degree of reinstatements to the left.

The lower surface of chair leg 4 is provided with the threaded adjusting bore 5 upwards extended, the height of threaded adjusting bore 5 is 1/2 of chair leg 4 height, threaded adjusting bore 5 internal thread is connected with height adjustment bolt 6, by the connecting length of adjustment four height adjustment bolt 6 with threaded adjusting bore 5, the height of seat 1 can be regulated; Also the connecting length of wherein one or more height adjustment bolt 6 and threaded adjusting bore 5 can be regulated, the upper surface of adjusting back 2 and the level of seat 1, thus the ground better adapting to classroom.

The below of chair leg 4 is also provided with the fastening support nut 7 be connected with the screw flight of height adjustment bolt 6, when height adjustment bolt 6 is adjusted to appropriate length with the connecting length of threaded adjusting bore 5, fastening support nut 7 can be adjusted to the position be close to chair leg 4 lower surface topmost, namely can further fastening height adjustment bolt 6, avoid it arbitrarily to rotate, the support force to chair leg 4 and whole seat can be increased again.

Be provided with the lumbar support projection 3 that rubber is made in the middle part of the lower end of the chair back 2 front end face, better can support the waist of student, avoid the lumbar strain that long-time sitting posture causes.
