Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, Fig. 2, a kind of automatic rotation compasses, comprise back shaft 1 and supporting leg 2, supporting leg 2 are provided with pencil 8.The lower end of back shaft 1 is provided with pivot portion 11, so that draw circle.The outside fixed cover of described back shaft 1 is connected to handle 12, and on described back shaft 1, movable sleeve is connected to going barrel 3, is provided with clockwork spring in described going barrel 3.One end of described clockwork spring is fixedly mounted on back shaft 1, the other end is fixedly mounted on going barrel 3, described supporting leg 2 is hinged on going barrel 3, the top of described back shaft 1 is provided with endoporus, the endoporus place of described back shaft 1 is vertically provided with push rod 5, the diameter of push rod 5 is less than the diameter of endoporus, so that the movement of push rod 5.The bottom of push rod 5 abuts the thimble 6 having L shape, and described thimble 6 comprises transverse part 61 and vertical part 62, and the bottom of push rod 5 is against on the transverse part 61 of thimble 6, and the needle tip of thimble 6 is provided with the upper end of vertical part 62.The transverse part 61 of thimble 6 is through push rod 5, and the sidewall of push rod 5 is provided with the groove 14 of transverse part 61 movable passageway as thimble 6, thimble 6 can move up and down in groove 14, but position can be subject to the restriction of back shaft 1.In addition, back shaft 1 preferably can be allowed to clamp the transverse part 61 of thimble 6, such thimble 6 is just not easy to drop from back shaft 1.
The bottom of described going barrel 3 is provided with locating hole 31, and the vertical part 62 of thimble 6 to be stretched in locating hole 31 and to be fixed by going barrel 3.Preferably, the quantity of described locating hole 31 is multiple, and the plurality of locating hole 31 circumference is evenly distributed on the bottom of going barrel 3, and the vertical part 62 being convenient to thimble 6 is like this stretched in locating hole 31 rapidly.After tightening clockwork spring, with hand upwardly thimble 6, the vertical part 62 of thimble 6 is entered in locating hole 31, thus fixes going barrel 3.Need picture bowlder, then promote push rod 5 downwards with hand, push rod 5 promotes again thimble 6 and moves down, and thimble 6 is separated with going barrel 3, then going barrel 3 is released, and going barrel 3 rotates, and the pencil 8 on supporting leg 2 can from animation circle under the elastic force effect of clockwork spring.In addition, the top of described push rod 5 is provided with the button 9 moved down for promoting push rod 5, the position that top is corresponding to button 9 of described handle 12 is provided with groove 91, the lower end of described button 9 is positioned at groove 91, the profile of product can be made so more attractive in appearance, and be convenient to finger press push rod 5 downwards.Need picture bowlder, rotation support shaft 1 can be carried out with hand grips said handle 12, more laborsaving like this; When need press button 9, can with after thumb and middle finger grips said handle 12, then with forefinger pressing button 9, operate just more convenient like this.
Described supporting leg 2 comprises connecting rod 21 and elastic device 7, and described connecting rod 21 is hinged on going barrel 3.Preferably, the bottom of described going barrel 3 is to being arranged with intermediate bar 32, and described intermediate bar 32 is vertically arranged, and the lower end of intermediate bar 32 is provided with bearing pin 33, described supporting leg 2 and going barrel 3 by bearing pin 33 and intermediate bar 32 hinged.Arranging of intermediate bar 32 one is the installation facilitating connecting rod 21, and two is facilitate connecting rod 21 to rotate the position adjusting pencil 8 around pin joint, the size of the required circle drawn of convenient adjustment.
Described elastic device 7 is hinged on connecting rod 21, described elastic device 7 comprises sleeve 70 and is arranged on upper piston part 71, Compress Spring 72 and the lower piston part 73 in sleeve 70, described Compress Spring 72 is between upper piston part 71 and lower piston part 73, Compress Spring 72 is vertically arranged, described upper piston part 71 is provided with piston rod 74, described piston rod 74 is hinged on connecting rod 21, lower piston part 73 is provided with for drawing round pencil 8.Piston rod 74 can rotate around pin joint, so that pencil 8 is adjusted to vertical state, picture bowlder Compress Spring 72 and lower piston part 73 apply a pressure straight down to pencil 8 always, by the nib pressure of pencil 8 on paper, thus the round even thickness that guarantee draws
In a word, as this product need be used to carry out picture circle, three steps can be divided carry out:
The first step, rotates going barrel 3 or back shaft 1 and tightens clockwork spring in going barrel 3, locking going barrel 3 in the locating hole 31 then allowing thimble 6 stretch on going barrel 3; Now, thimble 6 is by push rod 5 and button 9 also jack-up simultaneously.
Second step, adjust drawn diameter of a circle around pin joint pivot link 21, around pin joint rotating piston bar 74 and sleeve 70, make pencil 8 vertical with paper, and make pencil 8 bear Compress Spring 72 and the downward pressure of lower piston part 73, thus the nib of pencil 8 is made to be close to paper.
3rd step, presses the button 9 at back shaft 1 top, and push rod 5 promotes thimble 6 and moves down, and makes thimble 6 leave going barrel 3, then going barrel 3 and supporting leg 2 automatic rotation under the elastic force effect of clockwork spring draws circle.
The utility model can ensure picture compasses model, join end to end, and structure is simple, easy to operate, is very applicable to vast drawing librarian use.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
