Embodiment

Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment, belongs to the scope of protection of the invention.

With reference to Fig. 1, a kind of coordinatometer easy to draw is provided in the embodiment of the present invention, the coordinatometer includes bottom plate 100th, sliding block 200, right scale 300 and left scale 400, the 100 positive lower edges of bottom plate offer respectively to be parallel to each other Sliding slot 120, the quantity of the sliding block 200 is two, is slidably mounted on respectively in two sliding slots 120.In the present embodiment In, the sliding slot 120 is T-slot, and the bottom of the sliding block 200 is the T-shaped piece of insertion matched T-shaped piece with the T-slot The sliding block 200 is set to be slided in the sliding slot 120 in the T-slot.

The 100 positive concavity of bottom plate forms the Drawing zone 110 of rectangle, and two sliding slots 120 are located at respectively Above and below the Drawing zone 110.The 100 positive left and right sides of bottom plate is separately installed with a folder 130 of drawing, institute The clamping part for stating folder 130 of drawing is stretched into the Drawing zone 110.

Two sliding blocks 200 offer a scale slot, the both ends of the right scale 300 respectively on opposite sides It is slidably mounted on respectively in the scale slot of two sliding blocks 200, the both ends of the left scale 400 are also slidably mounted on two respectively In the scale slot of a sliding block 200.A rotatable bull stick 230, the right side are separately installed with two scale slots One end of scale 300 and one end of the left scale 400 are rotatably installed on one of them described bull stick 230, the right side The other end of scale 300 and the other end of the left scale 400 are rotatably installed on another described bull stick 230.

In the present embodiment, the scale slot offers a pair of of turn trough on opposite inner wall, and 230 both ends of bull stick are inserted Enter in two turn troughs and rotated in turn trough.

There is external screw thread, the end of the right scale 300 and left scale 400 offers turn hole, described on the bull stick 230 Have on the inner wall of turn hole and pass through the turn hole with the matched internal thread of the external screw thread, the bull stick 230 and be spirally connected.Described turn The right scale 300 and left scale 400 move in the opposite direction under the drive of screw thread when bar 230 rotates, i.e., described bull stick Externally threaded direction is identical on 230, and the right scale 300 is opposite with the internal thread direction in left scale 400；Or the bull stick There is the opposite external screw thread in two sections of directions, the right scale 300 is identical with the internal thread direction in left scale 400, and institute on 230 State right scale 300 and left scale 400 is separately mounted on two sections of external screw threads.

The 200 positive center of sliding block offers the through hole of bull stick 230 described in face, and being provided with the through hole 230 can Axially moveable scale fixed link 210, the scale fixed link 210 are supported on the bull stick 230 after pressing to prevent Bull stick 230 is stated to rotate.In the present embodiment, the scale fixed link 210 is and the bull stick 230 towards the face of the bull stick 230 The cambered surface of surface engagement, is provided with rubber antiskid layer in the cambered surface, to increase between the scale fixed link 210 and bull stick 230 Frictional force.Rubber antiskid layer is also installed on the through-hole side wall in the center of sliding block 200, prevents the scale fixed link 210 It is arbitrarily mobile.

Sliding block fixed link 220 is installed on the front of the sliding block 200, the sliding block fixed link 220 include screw rod and Nut connected vertically, the screw rod is through the sliding block 200 and opposite with the bottom plate 100, and the nut is located at the cunning The front of block 200.Graduation mark is respectively provided with the right scale 300 and left scale 400.

The coordinatometer when in use, drawing is placed in the Drawing zone 110 and is clamped using folder 130 of drawing, is then slided Move the sliding block 200 to adjust the right scale 300 and left scale 400 to suitable position, rotate the sliding block fixed link 220 Sliding block 200 is fixed on bottom plate 100, then slides the right scale 300 or left scale 400, by between two scales away from From adjusting, pressing the scale fixed link 210 makes the bull stick 230 stop operating, at this time the right scale 300 and left scale 400 are fixed on suitable position and suitable distance.

In conclusion a kind of coordinatometer easy to draw provided in an embodiment of the present invention, including bottom plate, sliding block, right scale And left scale, the quantity of sliding block is two, is slidably mounted on the positive lower edges of bottom plate respectively, and right scale and left scale are slided A bull stick is rotatablely equipped between two sliding blocks, inside each sliding block, two scales are slidably mounted on bull stick On, sliding slider and the position of two scales is adjusted during use, and the configuration of the present invention is simple is easy to use, being capable of Fast Drawing Go out satisfactory histogram.

Disclosed above is only several specific embodiments of the present invention, and still, the embodiment of the present invention is not limited to this, is appointed What what those skilled in the art can think change should all fall into protection scope of the present invention.
