With respect to prior art, the utlity model has following advantage: the chair that the utility model provides, simple in structure, easy to use, production cost is low; In addition, be provided with slide rail in the bottom of board, in the time using board, can on slide rail, slidably reciprocate by slide block, adjust board and the distance that is sitting in the user on seat, adapting to different users records custom on the one hand, has also adapted on the other hand different users's physique.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model board chair while routing up from armrest box.

In figure, seat 10, the chair back 11, board 20, chair foot rest 30, armrest box 40, cavity 41, handrail case lid 42, the first rotating shaft 43, connecting rod 45.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Upper and lower, forward and backward orientation described in the utility model refers to chair and is placed on floor, orientation when user is sitting on seat.

Referring to Fig. 1, the chair that a kind of board position is adjustable, comprise the chair foot rest 30 of the chair back 11, seat 10, board 20 and support seat 10, the chair back is fixedly connected on chair foot rest, laterally be fixedly installed the second rotating shaft in chair foot rest 30 lower ends, the two ends of the second rotating shaft are fixedly connected on respectively on chair foot rest, and the rear end of seat 10 and the second rotating shaft are rotatably connected, and seat 10 can be spun upside down taking the second rotating shaft as axle; The both sides of seat 10 are respectively equipped with pair of armrests case 40, armrest box 40 is fixedly installed on chair foot rest 30, on armrest box, also there is cavity 41 upper end open and that can hold board 20, be provided with the first rotating shaft 43 in the top cross of armrest box 40 front ends, the first rotating shaft 43 is positioned at cavity 41, in the first rotating shaft 43, be fixed with the connecting rod 45 that is 90 ° of angles with the first rotating shaft 43, i.e. the first rotating shaft becomes to be fixedly connected with connecting rod and is mutually vertical; The downside of board in the time of transverse state is provided with slide rail, and slide rail is 30 ~ 60 ° with respect to horizontal angle; The free end of connecting rod 45 is provided with can be along the slide block slidably reciprocating at slide rail, the free end of slide block and connecting rod is rotatably connected by the 3rd rotating shaft and board 20 along the setting of slide rail length direction, slide rail and horizontal angle are 30 ~ 60 °, in the time that board slidably reciprocates on slide rail by slide block, adjust board and the distance that is sitting in the user on seat, recorded custom thereby adapt to different users.Slide rail can be two that are parallel to each other, and is more conducive to support board.Connecting rod rotates taking the first rotating shaft as axle, drives board together to rotate, thereby board is taken out from cavity 41.The position of elbow while being sitting on seat for the position of connecting rod rotation is just in time arranged on to user, being convenient to user writes, the connecting rod position limiting structure of restriction connecting rod turned position need to be set, this connecting rod position limiting structure can adopt locating part common in prior art, in the utility model, preferably adopt the groove that is arranged on armrest box 40 front side wall tops, connecting rod 45 is with groove matched in clearance and limit the position that connecting rod 45 rotates taking the first rotating shaft as axle, connecting rod rotates taking the first rotating shaft as axle, last connecting rod proceeds to and in groove, has limited it and continue to rotate.

The free end of connecting rod is rotatably connected by the 3rd rotating shaft and board along the setting of slide rail length direction, board is rotated taking the 3rd rotating shaft as axle, in order to make board just in time in horizontal state, being convenient to user writes, the board position limiting structure of restriction board 20 turned positions need to be set, this board position limiting structure can adopt the common locating part of prior art, the utility model has preferred employing to be fixedly connected on connecting rod 45 and the block of horizontally set, the junction of block and connecting rod 45 is positioned at board 20 belows, the angle of block and horizontal direction defines the angle of board and horizontal direction, for the ease of writing, block best level arranges, in addition in order to improve the stability of level of board, multiple blocks can be set, multiple blocks arrange along connecting rod length direction, and the junction of multiple blocks and connecting rod is all positioned at the below of board, board is taken out from cavity, downwards upset board until the bottom of board contact with block, the arranging of block limited board and continued to rotate, simultaneously also for board provides certain supporting role.

When the adjustable chair in the board position that provides of the utility model is provided, first be rotationally connected bar taking the first rotating shaft as axle, board is taken out from cavity, after connecting rod is engaged in groove, rotate taking the 3rd rotating shaft as axle with board again, until board contacts with block.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
