Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1-Fig. 7, a kind of clipboard installing mechanism, comprises following part:
Axle bed 1, described axle bed 1 is arranged on the front end of armrests, and the center of axle bed 1 is provided with cylindrical cavity, and in cavity, the inner surface of axle bed 1 is provided with fin 11, and side has the first through hole 12.
Lower connecting axle 2, the lower end of described lower connecting axle 2 is provided with footstalk, the curved surface of footstalk offers screw 24, the groove 21 matched with fin 11 is provided with in the lower end of lower connecting axle, described footstalk grafting enters in the cylindrical cavity of axle bed 1 center, and makes fin 21 grafting enter in groove 21, is threaded through the first through hole 12 by screw 6 with screw 24, the screw terminal of screw 6 exposes with outside the first through hole, thus lower connecting axle is fixed on axle bed.Be provided with the internal threaded column 23 of protrusion in the middle part of the upper surface of lower connecting axle 2, the upper surface of lower connecting axle 2 is provided with arc bump 22 near the position of edge.
Upper connecting axle 3, the second through hole 31 is provided with in the middle part of the lower surface of described upper connecting axle 3, another opening direction of second through hole 31 is in the side of upper connecting axle 3, the lower surface of upper connecting axle 3 is provided with the width of the first deep-slotted chip breaker 31, first deep-slotted chip breaker 31 and arc bump 22 thickness near edge region is equal.When upper connecting axle is connected with lower connecting axle, internal threaded column 23 inserts in the second through hole 31, and screw 6 inserts from the other end of the second through hole 31 and is threaded with internal threaded column 23, and the screw terminal of screw is exposed to outside the second through hole.Arc bump 22 plugs together in the first deep-slotted chip breaker 31, and by cooperation between the two, the angle that connecting axle 3 is rotated is controlled within a certain range, and the situation being unlikely to occur turning over head occurs.The upper surface of upper connecting axle 3 keeps to the side and is partly provided with the second deep-slotted chip breaker 33, is provided with threaded post in the middle part of the upper surface of upper connecting axle 3.
Clipboard, comprises junction steel plate 4 and working plate 5.Described junction steel plate 5 is provided with the through hole matched with the threaded post be positioned in the middle part of upper connecting axle 3 upper surface, and screw 6 penetrates this through hole thus junction steel plate 4 can be rotated in the circumferential, and is fixed in the axial direction.The lower end of junction steel plate 4 is also provided with block 41, its thickness is equal with the width of the second deep-slotted chip breaker, and block 41 plugs together in the second deep-slotted chip breaker 33, and both match, thus the radian making clipboard rotate is controlled within a certain range, be unlikely to the phenomenon occurring turning over head.Working plate 5 is fixed on junction steel plate, at one jiao of circular groove be provided with for laying the things such as water tumbler of working plate 5.
As further optimization, when described arc bump 22 plugs together after in the first deep-slotted chip breaker 31, the rest radian of the first deep-slotted chip breaker 31 is 90 °, this design makes there are two extreme positions in upper connecting axle 3 rotation process, wherein during an extreme position, place, the upper surface plane of upper connecting axle 3 is parallel to the ground, and when another extreme position, the plane at the place, upper surface of upper connecting axle 3 is perpendicular to the ground.When described block plugs together after in the second deep-slotted chip breaker 33, the rest radian of the second deep-slotted chip breaker 33 is 90 °, and this design also meets clipboard and opens and the requirement of drawing in.
Clipboard described in the utility model can be fixed on the correct position in space, chair front upper place in use, is convenient to people's written record, in not used time, can draw the side being close to chair in, take additional space hardly, also not affect people and take a seat.In use, first rotate clipboard until can not rotate (now again, one end of block 41 and the second deep-slotted chip breaker 33 offsets), rotate upper connecting axle 3 again, until upper connecting axle 3 can not rotate (now, one end of arc bump 22 and the first deep-slotted chip breaker 32 offsets), now namely clipboard is fixed on the position being applicable to writing.When needs draw clipboard in, can first rotate connecting axle 3, until can not rotate (now, the other end of arc bump 22 and the first deep-slotted chip breaker 32 offsets), rotate clipboard again, till clipboard can not rotate (now, the other end of block 41 and the second deep-slotted chip breaker 33 offsets), complete the gathering of clipboard with this.
In order to weight reduction, also reduce material cost, described axle bed 1, lower connecting axle 2, upper connecting axle 3 and clipboard, except requisite functional structure, remainder is hollow design simultaneously.
