以下结合本实用新型实例作进一步说明: Below in conjunction with the utility model example for further description:
如附图1、图2中,桌椅可实现椅面的折叠功能,主要包括书桌面5、支撑架15和椅面17,其中书桌面5设置在支撑架15的上部,椅面17设置在支撑架15的中部。当椅子处于完全展开时,如图1所示,用手向上翻转椅面17,椅面17末端的连接杆24带动与连接杆24铰接的滑块10在后支撑杆内滑槽11内滑动,直到椅面17翻转到竖直状态时,椅面17可以靠在支撑架15上,滑块10也刚好到达后支撑杆13的下极限位置,这时椅子收拢。当使用椅子的时候,向下翻转椅面17,带动椅面17的连接杆24转动,椅面末端的连接杆与后支撑杆13的内滑槽11里的滑块10铰接,这样使得滑块10在后支撑杆内滑槽11里面向上滑动,当椅面17达到水平位置的同时滑块滑动到后支撑杆内滑槽11的上极限位置。 As shown in Figure 1 and Figure 2, the desk and chair can realize the folding function of the seat surface, mainly including the desk surface 5, the support frame 15 and the chair surface 17, wherein the desk surface 5 is arranged on the top of the support frame 15, and the chair surface 17 is arranged on the top of the support frame 15. The middle part of support frame 15. When the chair is fully unfolded, as shown in Figure 1, the chair surface 17 is turned up by hand, and the connecting rod 24 at the end of the chair surface 17 drives the slide block 10 hinged with the connecting rod 24 to slide in the inner chute 11 of the rear support rod. When the chair surface 17 is overturned to the vertical state, the chair surface 17 can lean against the support frame 15, and the slide block 10 also just arrives at the lower limit position of the rear support rod 13, and at this moment the chair is folded. When using the chair, turn down the chair surface 17 to drive the connecting rod 24 of the chair surface 17 to rotate, and the connecting rod at the end of the chair surface is hinged with the slider 10 in the inner chute 11 of the rear support rod 13, so that the slider 10 slides upwards in the inner chute 11 of the rear support rod, and when the seat surface 17 reaches the horizontal position, the slide block slides to the upper limit position of the inner chute 11 of the rear support rod.
参考图2、图3,桌椅可以实现椅子的升降功能。当椅面17达到了基本与支撑架15平行时,椅面17的转轴19的末端锁合在支撑架15的下棘条18内,后支撑杆13的顶端锁合在支撑架15的上棘条8内,这样向上提起椅面17,带动后支撑杆13整体向上移动,同步改变椅面17的转轴19末端、后支撑杆13的顶端在上下棘条内的位置,可实现椅面在新的高度下的锁合。 Referring to Fig. 2 and Fig. 3, the table and chair can realize the lifting function of the chair. When the chair surface 17 was substantially parallel to the support frame 15, the end of the rotating shaft 19 of the seat surface 17 was locked in the lower spine 18 of the support frame 15, and the top end of the rear support rod 13 was locked on the upper spine of the support frame 15. In the bar 8, lift the seat surface 17 upwards like this, drive the rear support rod 13 to move upwards as a whole, and synchronously change the positions of the rotating shaft 19 end of the chair surface 17 and the top of the rear support rod 13 in the upper and lower spines, so that the seat surface can be realized in the new position. lock at a height of .
参考图1、图4,桌椅可实现小抽屉拉出和收进、书桌面5与抽屉面7的分离与整合功能。书桌面5下有小抽屉4,小抽屉4可以在书桌面5里滑动伸缩。书桌面5的左右两侧各铰接有双连接片6与下抽屉面7铰接,使得下抽屉面7能绕书桌面5的固定端转动。当下抽屉面7与书桌面5处于展开位置时,向上转动下抽屉面7,直到与书桌面5缩合成为一个整体。当下抽屉面7与书桌面5缩合时,向下转动下抽屉面7,直到下抽屉面7与支撑架15的凹槽23扣合。 Referring to Fig. 1 and Fig. 4, the desk and chair can realize the functions of pulling out and retracting small drawers, separating and integrating the desk surface 5 and the drawer surface 7. There is a small drawer 4 under the desk top 5, and the small drawer 4 can slide and expand in the desk top 5. The left and right sides of the desk top 5 are respectively hinged with double connecting pieces 6 and are hinged with the lower drawer face 7, so that the lower drawer face 7 can rotate around the fixed end of the desk top 5. When the lower drawer surface 7 and the desk surface 5 are in the expanded position, the lower drawer surface 7 is rotated upward until it is condensed with the desk surface 5 to form a whole. When the lower drawer surface 7 is condensed with the desk top 5 , turn the lower drawer surface 7 downward until the lower drawer surface 7 is engaged with the groove 23 of the support frame 15 .
参考图1、图5,桌椅可实现画板撑、书立的功能。书立面1在书桌面5上,且其下端与伸缩杆2的一端铰接,当伸缩杆2的另一端在槽21内的棘条20里移动就可以改变书立面1的倾斜度。 Referring to Figure 1 and Figure 5, the tables and chairs can realize the functions of drawing board support and book stand. The book facade 1 is on the desk 5, and its lower end is hinged with an end of the telescopic rod 2. When the other end of the telescopic rod 2 moves in the spine 20 in the groove 21, the inclination of the book facade 1 can be changed.
参考图6、图7,桌椅可实现书桌面和抽屉面的整体隐藏功能。书桌面和抽屉面缩合后的整体向上翻转到竖直状态就可以在支撑架15中的滑槽9中缓慢放下,就可以藏到支撑架内滑槽9里面。将书桌面5从滑槽9中拉出到最上端即外伸端25刚好和支撑架内滑槽9的最上端顶住,那么书桌面5便可以绕着外伸端翻转到水平位置。 Referring to Fig. 6 and Fig. 7, the desk and chair can realize the overall hidden function of the desk top and the drawer surface. After the desk top and the drawer face are condensed, the whole is upturned to the vertical state and can be slowly put down in the chute 9 in the support frame 15, and can be hidden in the chute 9 inside the support frame. The desk top 5 is pulled out from the chute 9 to the uppermost end, that is, the overhanging end 25 just bears against the uppermost end of the chute 9 in the support frame, so the desk top 5 can turn over to a horizontal position around the overhanging end. the
参考图1、图8、图9,桌椅可实现自由排列组合的功能。在支撑架15上设置快速接头12、凸轴16,使一张桌椅快速接头12能与另外一张桌椅凸轴16组合在一起。这样就可以利用桌椅与桌椅之间的快速接头12、凸轴16来相互配合,达到自由排列组合的目的。 Referring to Fig. 1, Fig. 8, and Fig. 9, the tables and chairs can realize the functions of free arrangement and combination. A quick connector 12 and a protruding shaft 16 are arranged on the support frame 15, so that a table and chair quick connector 12 can be combined with another table and chair protruding shaft 16. In this way, the quick connectors 12 and the protruding shafts 16 between tables and chairs can be utilized to cooperate with each other to achieve the purpose of free arrangement and combination.
本实用新型的有益效果是:实现桌椅一体化,占地面积小,节省空间,防尘;能置放画板或书籍;能升高和降低椅面;可灵活移动桌椅,实现自由排列组合;并且采用了平行四边形机构,曲柄滑块机构,棘条机构可用于机械设计课程的教学展示。 The beneficial effects of the utility model are: realizing the integration of tables and chairs, occupying a small area, saving space, and being dust-proof; drawing boards or books can be placed; the chair surface can be raised and lowered; tables and chairs can be flexibly moved to realize free arrangement and combination ; And the parallelogram mechanism, the slider crank mechanism and the ratchet mechanism can be used for the teaching demonstration of the mechanical design course.
