Description

A kind of curled portable drawing board

Technical field

the utility model relates to drawing instrument, especially relates to a kind of coiled-type, portable drawing board.

Background technology

Drawing board is the workbench of design, drawing use, is mainly used in the fields such as drawing, engineering, design, clothes.That traditional drawing board material has is wooden, synthetic material etc.Existing drawing board is mostly rectangle boarding, has the defect large, shape is fixed, mobility is poor that takes up room.

And existing folding plotting plate investigative technique has a lot, great majority can only fold once or twice, and actual effect is not obvious, folding operation complexity, be difficult to reach the convenient requirement of carrying of drawing board, and the problem of folding drawing board surface smoothness is not well solved.

If drawing board is realized can curlingization, portability and improve drawing board surface smoothness, can greatly improve above problem, chart board is easy to carry, take up an area space little, with the larger effect of performance in working and learning.

Summary of the invention

In order to overcome the defect of existing drawing board, the utility model aims to provide a kind of curled portable drawing board of moving and carry and flatness being good be convenient to.

The utility model is realized above-mentioned purpose and has been adopted following technical scheme:

A kind of curled portable drawing board, by some length consistent U-shaped frid be spliced, described frid is divided into two groups of A, the B that quantity is equal, every group of frid comprises the end plate being rotationally connected by hinge, some intermediate plates and a connecting plate, the connection hinge of A group frid is arranged at outside, frid turning, the connection hinge of B group frid is arranged at the outside, edge of frid, between A, two groups of frids of B, is connected by connecting plate; On the side plate of described frid, be symmetrical arranged between two four arc binding grooves that are greater than semicircle, binding groove is provided with the thin bar being mated.

Curled portable drawing board, also comprises two end caps, and end cap center arranges curling cylinder, and end cap sidewall arranges locating hole.

Described thin bar is that two and one end are screw thread with flange, the other end, and the wing nut matching is set on screw thread.

Also comprise a rubber blanket equating with drawing board area.

The curled portable drawing board of the present utility model that adopts above technical pattern, drawing board can be curled into tubular, and body takes up room little, is convenient for carrying, and is applicable to picture personnel and carries at a distance drawing board; Assembling process need be only plane by tubular plate development and reinforce by elongate rod, when dismounting, only cell board assembly need be centered around on cylinder, has avoided because parts too much cause assembling process loaded down with trivial details.

Detailed description of the invention

The description of symbols relating in accompanying drawing: 1-A organizes frid, 11-end plate, 12-intermediate plate, 13-connecting plate; 2-B organizes frid, 21-end plate, 22-intermediate plate, 23-connecting plate;

3-rubber blanket, 4-thin bar, 5-end cap, 6-binding groove, 7-pin rod, 8-pin-and-hole, 9-locating hole, 10-wing nut.

The technical scheme of the curled portable drawing board below in conjunction with accompanying drawing to the utility model embodiment is elaborated.

As shown in Figure 2,4, curled portable drawing board, comprises U-shaped A group frid 1 that length is consistent, B group frid 2, rubber blanket 3, two thin bars 4 and end cap 5; A group frid 1 comprises an end plate 11, six intermediate plates 12 and connecting plates 13, B group frid 2 comprises an end plate 21, six intermediate plates 22 and connecting plates 23, on the side plate of described frid, be symmetrical arranged between two four arc binding grooves 6 that are greater than semicircle, thin bar 4 can be inserted binding groove 6 and coordinate.

As shown in Figure 5, outside two turnings of end plate 11, upper and lower part respectively arranges a pin rod, as shown in Figure 6, two turnings of intermediate plate 12 a: side respectively arranges up and down a pin rod, opposite side one pin-and-hole is respectively set up and down, as shown in Figure 7, two outsides, turning of connecting plate 13 and the edge of a side plate: the upper and lower pin-and-hole that respectively arranges.

As shown in Figure 8, the upper and lower pin-and-hole that respectively arranges in side plate edge of end plate 21, as shown in Figure 9, the biside plate edge of intermediate plate 22 a: side respectively arranges up and down a pin rod, opposite side one pin-and-hole is respectively set up and down, as shown in figure 10, the biside plate edge of connecting plate 23 and the outside at a turning: the upper and lower pin rod that respectively arranges.

Above-mentioned pin rod inserts the formation hinge that matches in pin-and-hole, thus realize the gemel connection of adjacent two frids and by curling separately with B group frid A group be a tubular.

As shown in figure 11, end cap 5 centers arrange curling cylinder, and end cap sidewall arranges locating hole 9.

As shown in figure 12, one end of thin bar 4 is screw thread with flange, the other end, and screw thread can match with wing nut 10.

When expansion, as shown in Figure 2, the mutual gemel connection of intermediate plate by A group with B group, end plate and connecting plate are separately connected to the two ends of spliced intermediate plate, finally two connecting plates are connected, thin bar 4, successively through the binding groove of each frid and wing nut is tightened to the end of thread of thin bar 4, is taped against rubber blanket 3 to the plane of A group after connection and B group frid composition.

When curling, A is organized to frid 1 and B group frid 2 to be separated between connecting plate, connecting plate 13 is connected to end plate 11, connecting plate 23 is connected to end plate 21, thereby form respectively tubular as shown in Figure 4, due to the curl direction difference of two groups of frids, after curling, the side plate of A group frid is outside, and the side plate of B group frid is inside, being convenient to that B is organized to frid is placed on outside A group frid, by thin bar 4 and curling after rubber blanket 3 insert in the cylinder that A group frid forms, then end cap 5 is covered respectively to the upper of curling drop end, lower end and with inserted link insert locating hole 9 be fixed, as shown in Figure 3.

Curled portable drawing board of the present utility model, by drawing board be divided into can be curling some frids, and utilize hinge structure to connect and utilize thin bar to be fixed, realized the convenient mobile of drawing board and carried, and easy and simple to handle, be conducive to improve Plot Work efficiency.
