Abstract

The utility model relates to compasses with a sucker. The compasses comprise a circle center supporting rod and a drawing supporting rod which are connected with each other through a connection piece to form a whole body, wherein the circle center supporting rod comprises an outer cylinder and an inner rod arranged in the outer cylinder in a penetrating manner; the upper end and the lower end of the outer cylinder are respectively and fixedly connected with the outer ring of each rotating bearing; the inner rod is fixedly arranged in the inner rings of the upper and lower rotating bearings in a penetrating manner; the extending end at the lower end of the inner rod is fixedly connected with the sucker; the drawing supporting rod is connected with the cylinder wall of the outer cylinder through a connection piece in a positioning manner; and the top part of the outer cylinder is fixedly connected with a rotating handle. The height of the drawing supporting rod relative to the cylinder wall of the outer cylinder and the inclined angle of the drawing supporting rod relative to the axial direction of the outer cylinder can be suitably adjusted through the connection piece. The sucker adopts a vacuum rubber sucker; the rotating bearings are ball bearings. The compasses thoroughly and effectively solve the problems that the conventional compasses are not stable, are easy to make mistakes when being used for drawing a picture, and are liable to damage objects such as paper or a blackboard and to accidently hurt people when being operated improperly.

Description

A kind ofly be with suctorial compasses

Technical field

The utility model belongs to the drawing instrument technical field, relates to a kind of compasses, especially a kind ofly is with suctorial compasses.

Background technology

Compasses of the prior art, mostly consisted of by center of circle support bar and the combination of drawing support bar, during drawing, the location in the center of circle all is to realize by the feet that is arranged on support bar bottom, the center of circle, what the feet of existing compasses mostly adopted on the market is a draw point that be arranged in parallel with the support bar axis, obviously there is following problem in the use of this locating steel needle:

1. when drawing, only rely on a draw point location easily, but because the support of draw point is unstable, very easily produce mistake during drawing;

2. rely on the draw point location, during drawing, draw point can rotate together along with compasses integral body, very easily damage is caused on the surface of draw used paper or blackboard etc.;

3. in the use procedure, the careless slightly unexpected injury that is easy to cause to human body.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art or defective, and a kind of suctorial compasses of being with are provided, and is unstable when solving traditional drawing for compasses, easily makes mistakes, and the article such as paper or blackboard are caused damage, and the misoperation easy accident problem such as hurt sb.'s feelings also.

To achieve these goals, the utility model has adopted following technical scheme:

A kind ofly be with suctorial compasses, comprise the center of circle support bar and the drawing support bar that are connected as a single entity by connector; It is characterized in that,

Described center of circle support bar comprises a urceolus and the interior bar that is located in this urceolus;

Described urceolus upper/lower terminal is affixed with the outer ring of a rolling bearing respectively;

Described interior bar fixedly is located in the inner ring of described upper and lower rolling bearing; Wherein, external part and a sucker of interior bar lower end are fixedly linked;

Described drawing support bar is located by connecting on the barrel of described urceolus by connector;

The top of described urceolus and a turning handle are fixedly linked.

Above-mentioned be with suctorial compasses, wherein,

Between the inner ring of described interior bar and described rolling bearing with and and sucker between be interference fit.

Described drawing support bar can be adjusted by appropriateness about the described connector with respect to the height of urceolus barrel.

Angle between described drawing support bar is axial with respect to described urceolus can be regulated by described connector appropriateness.

Described sucker is the vacuum rubber sucker.

Described rolling bearing is ball bearing.

Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect:

1. because the center of circle of the present utility model support bar has adopted urceolus to add the structure of interior bar, driving the urceolus rotation by the bearing that links to each other with interior bar draws, utilization is connected to interior bar bottom chuck and positions, make the positioning supports of compasses more stable, the center of circle is difficult for the generation displacement and mistake occurs during drawing;

2. the use of sucker can be protected the surface of paper or blackboard etc., the unlikely damaged surfaces that causes paper or blackboard effectively;

3. avoid existing compasses needle point because careless manipulation and unexpected injury that human body is caused.

The specific embodiment

Referring to Fig. 1, cooperate referring to Fig. 2～Fig. 5, the utility model relates to a kind ofly is with suctorial compasses, comprises the center of circle support bar 1 and the drawing support bar 2 that are connected as a single entity by connector.

The key of technical solutions of the utility model is:

Center of circle support bar 1 comprises a urceolus 11 and the interior bar 12 that is located in this urceolus 11; Urceolus 11 upper/lower terminals are affixed with the outer ring 31 of a rolling bearing 3 respectively; Interior bar 12 fixedly is located in the inner ring 32 of upper and lower rolling bearing 3;

Wherein, as shown in FIG., external part and a sucker 5 of interior bar 12 lower ends are fixedly linked.

Drawing support bar 2 is located by connecting on the barrel of urceolus 11 by connector 6.

The top of urceolus 11 and a turning handle 4 are fixedly linked.

During assembling, preferably adopt interference fit between the inner ring 32 of interior bar 12 and rolling bearing 3 and between interior bar 12 and the sucker 5, but the production of product batch machining.

Drawing support bar 2 can be as required with respect to the barrel height of urceolus 11 by connector about in the of 6 appropriateness adjust.

Drawing support bar 2 can be regulated by connector 6 appropriateness as required with respect to the included angle A between urceolus 11 axis.

In order to make the compasses positioning stablity, sucker 5 preferably adopts the vacuum rubber sucker, and like this, compasses are with respect to comprising between the drawing surface that paper or blackboard etc. just can not produce the situation of displacement, guarantee to draw accurately.

As shown in Figure 3, the rolling bearing 3 that relates to of the utility model is ball bearing.
