Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, folding seat of the present utility model, comprise cushion 4, two front support pin, two rear support pin 2 and clipboard 3, described front support pin is connected on cushion 4, described rear support pin 2 is connected on cushion 4, and described clipboard 3 is connected on two front support pin, and described front support pin is made up of support bar 1 and backstay 8, described backstay 8 is with support bar 1 for being rotatably connected, and described clipboard 3 is connected on backstay 8; Also comprise connecting rod 7 and expansion link, described connecting rod 7 is hollow structure, and described expansion link is made up of small end 5 and large end 6, and one end of connecting rod 7 and backstay 8 are rotatably connected, the other end is enclosed within on the small end 5 of expansion link, and large end 6 and the support bar 1 of described expansion link are rotatably connected; Also comprise ratchet, described ratchet is made up of wheel disc 9, ratchet 10, spring 11, and described wheel disc 9 is fixedly mounted on backstay 8, and described ratchet 10 is rotatably connected on support bar 1, and described spring 11 one end are connected with ratchet 10, and the other end is connected with support bar 1.Due to backstay 8 with support bar 1 for being rotatably connected, and clipboard 3 is connected on backstay 8, therefore only need to be towards horizontal direction rotational positioning bar 8 in the time that people with a part in a conference person need to write, clipboard 3 is turned to thereupon and be applicable to just can on clipboard 3, writing easily after the angle of oneself writing.As long as rotational positioning bar 8, make backstay 8 turn to clipboard 3 time in alignment with support bar 1 and just can accept as backrest and use when not needing to write.When backstay 8 drives clipboard 3 to rotate, connecting rod 7 and expansion link also can correspondingly rotate, and connecting rod 7 also can move relative to expansion link.The small end 5 that should ensure in the specific implementation expansion link has enough length, also can not separate with expansion link to make backstay 8 turn to connecting rod 7 time in alignment with support bar 1.For the angle the utility model that facilitates people with a part in a conference person to adjust clipboard 3 according to individual writing style is also provided with ratchet.People with a part in a conference person first turns to lower position by clipboard 3 in use, then ratchet 10 is inserted in wheel disc 9, then upwards rotate clipboard 3 to suitable angle, because ratchet has anti-non-return effect, even if therefore people with a part in a conference person has applied downward active force to clipboard 3 in writing process, ratchet also can not rotate the support of ratchet 10 is little, for clipboard 3 provides reliable support.
In order to facilitate people with a part in a conference person to adjust the distance of clipboard 3 distances oneself, described clipboard 3 is provided with slide block with the both sides that backstay 8 is connected, and on described backstay 8, is provided with sliding tray, and described slide block matches with sliding tray.As long as pull with hand clipboard 3 when use, just clipboard 3 can slide in the sliding tray of backstay 8, clipboard 3 and the relative position of backstay 8 can be adjusted in real time.
On described backstay 8, be provided with length indication bar.People with a part in a conference person needs some figure of picture sometimes, and pure manual picture size deviation ratio is larger, therefore on backstay 8, length is set and represents bar, like this can be by writing paper near length indication bar, and utilize length to represent that bar improves the precision of drawing.When concrete enforcement, length represents that bar can adopt thin steel ruler, can thin steel ruler be fixed on backstay 8 by the method for riveted joint.
On described clipboard 3, be also provided with a groove.In order to facilitate personnel participating in the meeting to place the pen of writing use in the intermittent time of writing, the utility model is also provided with a groove.When concrete enforcement, the cross section of a groove can be semicircle, and the Length Ratio of a groove writes the long of use, can easily pen be taken out from a groove like this.
As shown in Figure 3, also comprise doubling expansion board 13, described doubling expansion board 13 is rotatably connected by loose-leaf with clipboard 3.In order to solve the too little not enough situation of clipboard 3 area, can set up doubling expansion board 13.When doubling expansion board 13 is not used, can be folded on original clipboard 3, in the time that needs increase write area, rotate clipboard 3 and make its expansion.When concrete enforcement, loose-leaf is arranged on the upper surface of doubling expansion board 13 and clipboard 3.
As shown in Figure 4, also comprise flexible expansion board 14, described clipboard 3 is hollow structure, and described clipboard 3 is set in flexible expansion board 14, and described flexible expansion board 14 is removable connection with clipboard 3.In order to solve the too little not enough situation of clipboard 3 area, in only using clipboard 3, do not take again too much space, design flexible expansion board 14.Flexible expansion board 14 is put into the inside of hollow clipboard 3 in the time not using, and can't take outside space; Need to use expansion plate time, expansion plate is hauled out from clipboard 3.The mobile link that when concrete enforcement, flexible expansion board 14 and clipboard 3 are can adopt the form of slide block and chute, can chute be set at clipboard 3 inwalls, in the two side of flexible expansion board 14, slide block is set.
