Abstract
The utility model discloses a pair of novel compasses which comprise a compass head with a handle, a positioning pin leg and a pen leg, wherein the upper ends of the positioning pin leg and the pen leg are altogether hinged on the compass head, and the handle is fixed at the top of the compass head; through holes are respectively interpenetrated on the positioning pin leg and the pen leg along the direction of opening and closing the positioning pin leg and the pen leg, and a guide rod penetrates in the two through holes; the through holes on the positioning pin leg and the pen leg are thread holes in opposite thread directions; the guide rod is a threaded rod with a thread; a regulating element positioned between the positioning pin leg and the pen leg fixedly penetrates the threaded rod, and the thread directions of the threaded rod positioned on both sides of the regulating element are opposite and respectively correspond to the corresponding threads of the thread holes. Compared with the prior art, the utility model has the advantages that the hinged part of the positioning pin leg and the pen leg of the compasses is not dislocated, thereby prolonging the service life of the compasses; and the opening degree between the positioning pin leg and the pen leg can be finely adjusted, thereby improving the accuracy of a circle drawn by the compasses.
Description
Technical field
The utility model relates to a kind of how much draw tools, specifically is a kind of compasses.
Background technology
Compasses generally are made of the compasses head with handle, pilot pin leg and a leg, and the upper end of a pilot pin leg and a leg is articulated on the compasses head jointly, and handle is fixed in the top of compasses head.Existing this compasses before will drawing, must will be broken folding degree to correspondence off with the fingers and thumb with hand between a pilot pin leg and the leg according to the radius of the circle that will draw or circular arc, and the folding degree is directly broken off with the fingers and thumb with hand between a pilot pin leg and the leg, and accuracy is relatively poor; And location stitch and a pin since folding often, its hinge point misplaces easily, makes to locate stitch and a pin not at grade, causes compasses to use, service life is shorter.
The utility model content
The purpose of this utility model has provided long, the higher novel bow compass of accuracy in a kind of service life.
The utility model adopts following technical proposals to achieve these goals: a kind of novel bow compass, comprise compasses head, pilot pin leg and a leg with handle, and the upper end of a pilot pin leg and a leg is articulated on the compasses head jointly, and handle is fixed in the top of compasses head; An above-mentioned pilot pin leg and a leg connect respectively along the direction of their foldings and offer through hole, are equipped with a guide post jointly in these two through holes.
Through hole on an above-mentioned pilot pin leg and the leg is the opposite screw of hand of spiral, above-mentioned guide post is the screw rod with screw thread, fixedly be equipped with the adjusting parts between an above-mentioned pilot pin leg and a leg on this screw rod, it is opposite and correspond respectively to the screw thread of above-mentioned corresponding screw that above-mentioned screw rod is positioned at the hand of spiral of above-mentioned adjusting parts both sides.
Above-mentioned adjusting parts are adjusting handle, and above-mentioned screw rod vertically passes the center of circle of this adjusting handle, and the periphery of this adjusting handle is provided with the burr that is beneficial to hand-held rotation.
After adopting technique scheme, owing to be equipped with guide post jointly between pilot pin leg and the leg in the utility model, and this guide post cooperates screw and regulates parts and can finely tune the folding degree between a pilot pin leg and the leg.Compared with prior art, the hinge point of a bow compass positioning pin leg of the present utility model and a leg can not misplace, and has prolonged the service life of compasses; And the folding degree between a pilot pin leg and the leg is fine-tuning, and the round accuracy of drawing like this is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of pilot pin leg and a leg in the utility model.
The specific embodiment
A kind of novel bow compass of the present utility model as shown in Figure 1, 2, comprises compasses head 1, pilot pin leg 2, a leg 3, guide post 4 and adjusting handle 5 with handle 11.The upper end of a pilot pin leg 2 and a leg 3 is articulated on the compasses head 1 jointly, and handle 11 is fixed in the top of compasses head 1.
As shown in Figure 2, pilot pin leg 2 and a leg 3 upper edges offer through hole respectively perpendicular to the direction on this two plane, folding place, in this through hole respectively riveting be provided with pin 21,31, and the direction of pilot pin leg 2 and a leg 3 upper edge pilot pin legs 2 and a leg 3 foldings connects respectively and offers through hole 22,32, pin 21, offer respectively on 31 and through hole 22,32 corresponding and screws 211 that hand of spiral is opposite, 311, guide post 4 passes screw 211 respectively, 311 and through hole 22,32, guide post 4 is for having the screw rod of screw thread, the center of circle vertical fixing of adjusting handle 5 is arranged on the guide post 4 and between a pilot pin leg 2 and a leg 3, guide post 4 is positioned at the screw thread 42 of adjusting handle 5 left and right sides, 41 directions are opposite and correspond respectively to screw 211,311 screw thread.The periphery of adjusting handle 5 is provided with the burr that is beneficial to hand-held rotation.
In the utility model, because pilot pin leg 2 and a leg 3 connect respectively along the direction of their foldings and offer the opposite screw of hand of spiral 211,311, be equipped with a guide post 4 jointly in this screw 211,311, during use, a pilot pin leg 2 and a leg 3 open or close up along guide post 4 all the time, like this, the hinge point of a pilot pin leg 2 and a leg 3 just can not misplace, and has prolonged the service life of compasses.And, in the utility model, folding degree between a pilot pin leg 2 and the leg 3 can be broken off with the fingers and thumb with hand earlier roughly, because it is opposite and correspond respectively to the screw thread of screw 211,311 that guide post 4 is positioned at screw thread 42,41 directions of adjusting handle 5 left and right sides, a pilot pin leg 2 and a leg 3 just synchronously opened or close when adjusting handle 5 rotated, rotate adjusting handle 5 and just can finely tune the folding degree between a pilot pin leg 2 and the leg 3 this moment, and the round accuracy of drawing like this is higher.
Above-mentioned embodiment is an optimal way of the present utility model, is protection domain of the present utility model based on claim and the general embodiment of being made of expanding thereof simultaneously.
