Specific embodiment
Below in conjunction with accompanying drawing and a preferred embodiment, technical scheme is further described.
As shown in figure 1, being a kind of lens barrel balanced controls of the present embodiment, it includes one and is used for fixedly mounting lens cone for telescope 3 fixed pedestal 1, the upper surface of described fixed pedestal 1 is vertically arranged with two stators 2, and this two stators 2 are symmetrically spaced Setting, and it is arranged at the side of described fixed pedestal 1 upper surface;Lens barrel 3 is arranged between this two stators 2, described fixation The bottom of pedestal 1 is additionally provided with a plurality of legs 10, for supporting whole mechanism.
The outside of described stator 2 is provided with balanced component 20, described balanced component 20 include the first elastic component 201, Two elastic components 202, the first slide rail 203 and the second slide rail 204, described first elastic component 201 and the second elastic component 202 are preferably Extension spring.Described first elastic component 201 and the second elastic component 202 are arranged in a mutually vertical manner, one end of described first elastic component 201 and the One end of two elastic components 202 is fixedly connected.
Described first elastic component 201 and the first slide rail 203 are arranged in a mutually vertical manner, and described first elastic component 201 and first is sliding One end that rail 203 connects is provided with first sleeve 201a, and described first sleeve 201a is set on described first slide rail 203, real It is existing that both are slidably connected.
Described second elastic component 202 and the second slide rail 204 are arranged in a mutually vertical manner, and described second elastic component 202 and second is sliding One end that rail 204 connects is provided with the second sleeve pipe 202a, and described second casing pipe sleeve 202a is located on described second slide rail 204, real Show both be slidably connected.
When lens barrel 3 rotates, the first elastic component 201, the second elastic component 202 are sliding along the first slide rail 203 and second respectively Rail 204 slides relatively, keeps the gravity balance of lens barrel 3.
As shown in Fig. 2 its operation principle is:
Wherein, the first elastic component, the second elastic component coefficient of elasticity are k, and lens barrel gravity is g, and the lens barrel anglec of rotation is a, A → B is the glide direction of the first elastic component, and D → C is the glide direction of the second elastic component,
During lens barrel level:I.e. during a=0, now torque balance:T=k*r*r=g*R
After lens barrel rotational angle a, torque balance is analyzed as follows:
F1=k*r*(1-sina);h1=r*sina
F2=k*r*cosa;h2=r*cosa
Torque T1=F1*h2=k*r*r* (1-sina) cosa
Torque T2=F2*h1=k*r*cosa*r*sina
Torque sum that the left side is counterclockwise:T is inverse=T1+T2=k*r*r*cosa
The right clockwise torque:T is suitable=g*R*cosa
Because of k*r*r=g*R
Therefore:T is suitable=and T is inverse, i other words, left and right torque is equal, and lens barrel can be with self-balancing, under any anglec of rotation of lens barrel all Can guarantee that the balance of lens barrel center of gravity consolidates.
As shown in figure 3, when lens barrel 3 is in horizontality, two elastic components are all in the maximum state of pulling force, now permissible The weight of balance lens barrel;As shown in figure 4, when lens barrel 3 rotates an angle, when such as 45 °, two elastic components are in the effect of elastic force Under, relatively slide along respective slide rail direction respectively, the elastic force of elastic component also can change accordingly simultaneously, but two elastic components is total Torque just balances the torque produced by weight of lens barrel 3;As shown in figure 5, be in view when 90 ° for lens barrel 3.
In sum, present configuration is reasonable in design, can ensure lens barrel center of gravity under any anglec of rotation of lens barrel Balance consolidate, smoothly ensure precision and the track up to target of telescope measurement, there is extraordinary practical value.
Above-described embodiment only technology design to illustrate the invention and feature, its object is to allow person skilled in the art Scholar will appreciate that present disclosure and implements according to this, can not be limited the scope of the invention with this, all according to the present invention Equivalence changes or modification that spirit is made, all should be included within the scope of the present invention.
