Background technology
Thermal expansion and the variations in refractive index of lens of lens and lens barrel, can cause lens caused by temperature change meeting
The focal position of lens barrel changes to cause optical performance degradation.Particularly a part or lens barrel for lens is modeling
In the case that material material is made, thermal expansion, variations in refractive index can be bigger, and the deterioration of optical property can also become big.
In general, lens barrel is made up of multiple lens, lens barrel and multiple spacer rings, and lens pass through positioned at each lens
Between each spacer ring positioned in the direction of the optical axis, by defined adjusting apparatus, to lens barrel and imaging sensor
Relative positioning and fixation are carried out, so that imaging sensor face is in the range of the depth of focus of lens barrel.In this shape
Under state, along with variation of ambient temperature, it may occur that the variations in refractive index of lens, the thermal expansion of lens barrel and lens, so as to lead
The back focal length of lens barrel is caused to change, imaging sensor face offsets out the scope of the depth of focus of lens barrel, in this case,
The optical property of lens barrel will be deteriorated, so that performance when being unable to maintain that normal temperature.
In order to solve caused by variation of ambient temperature lens barrel back focal length change caused by optical performance degradation
Problem, at present, is generally provided for suppressing the mechanism that the focal position of this lens barrel changes in lens barrel（For example
Autofocus mechanism）, the back focal length of lens barrel and the relative position of imaging sensor can be corrected, it is bad to solve optical property
The problem of change, still, but this can cause lens barrel to become big, increase manufacturing cost.Even if in addition, having automatic change in lens barrel
Burnt mechanism, when the focal position of lens barrel changes with temperature change, the control range of autofocus mechanism
It can increase, as a result also result in the maximization of lens barrel.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of compact conformation, small band bullet is influenceed by temperature change
The lens barrel of spring spacer ring.
To solve the technical scheme that above-mentioned technical problem is used：A kind of lens barrel with spring spacer ring, including lens
Cylinder and the multiple lens located at lens barrel inner chamber, wherein between one group of adjacent lens provided with vary with temperature and
The elastic component of deformational displacement is produced on the optical axis direction of lens, the elastic component includes the spacer ring and spring of integrally connected,
It is located at the bushing of the restricted lens radial disbalance movement of setting-in at lens in the lens barrel inwall.
Further, the spring is helical spring, and the helical spring is by the first helical spring and the second helical spring
Two sections are connected to form, and first helical spring is connected with spacer ring, and the pitch of first helical spring is more than the second spiral
The pitch of spring.
Further, it is covered with skid-proof rubber film on the surface that second helical spring is contacted with lens.
Further, the spring is conical compression spring, the small-caliber end and spacer ring of the conical compression spring
It is connected.
Further, the spring is butterfly spring, and the small-caliber end of the butterfly spring is connected with spacer ring.
Beneficial effect：In this lens barrel with spring spacer ring, elastic component is set between adjacent two lens so that in mirror
Cylinder when size expands change, can coordinate the distance between lens, the temperature of energy fit lens becomes by temperature change
The optical property change produced after change, in elastic component spring by selecting appropriate coefficient of elasticity and material, it is final realize from
Dynamic adjusting focal length, it is simple in construction, greatly reduce the overall dimensions of lens barrel；In addition, when lens because temperature change causes footpath
During to change in size, the bushing on the outside of lens can support limitation lens generation and move radially, so as to be prevented effectively from appearance
Lens off-centring phenomena.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the structural representation of the utility model embodiment elastic member.
Embodiment
Referring to Figures 1 and 2, a kind of lens barrel with spring spacer ring of the utility model, including lens barrel 10 and be located at
The multiple lens of the inner chamber of lens barrel 10, wherein between one group of adjacent lens provided with vary with temperature and in the optical axis side of lens
The elastic component 30 of deformational displacement is produced upwards, and elastic component 30 includes the spacer ring 31 and spring 32 of integrally connected.
In the present embodiment, the multiple lens being arranged in lens barrel 10 include front and rear the first lens spaced successively
21st, the second lens 22, the 3rd lens 23, the 4th lens 24 and the 5th lens 25, elastic component 30 be arranged on the second lens 22 with
Between 3rd lens 23, elastic component 30 to adjust the second lens 22 and the 3rd lens 23 along the distance between optical axis direction,
Specifically, because the linear expansion coefficient of the components such as each lens, lens barrel is had nothing in common with each other, with temperature change, each scantling
Also it can change, by setting elastic component 30 between the second lens 22 and the 3rd lens 23, when size expands change
During change, the light produced after the distance between the second lens 22 and the 3rd lens 23, the temperature change of energy fit lens can be coordinated
Performance change is learned, spring 32 is by selecting appropriate coefficient of elasticity and material in elastic component 30, it is possible to achieve adjust automatically is burnt
Away from abandoning tradition sets up the structure type of autozoom mechanism, greatly reduces the physical dimension of lens barrel.
Though it can effectively pass through the second lens 22 by setting elastic component 30 between the second lens 22 and the 3rd lens 23
Effectively to suppress the variation of the focal position of lens barrel with the interval increase and decrease of the 3rd lens 23 in the direction of the optical axis, but can not
Avoid because of the eccentric phenomena between the lens caused by the change in size diametrically of the lens caused by temperature change, accordingly,
The inwall of lens barrel 10, which is located at lens, is embedded with bushing 11, and bushing 11 selects material independent of temperature variations, works as lens
When causing the radial dimension to change because of temperature change, the bushing on the outside of lens, which can support limitation lens and produce, to be moved radially,
There is lens off-centring phenomena so as to be prevented effectively from.
Preferably, spring 32 is helical spring, helical spring is by two sections of phases of the first helical spring and the second helical spring
Even formed, the first helical spring is connected with spacer ring 31, wherein, the pitch of the first helical spring is more than the section of the second helical spring
Away from so that the second helical spring end is contacted with the 3rd lens 23 formation larger area.
In addition, being covered with skid-proof rubber film 33 on the surface that the second helical spring is contacted with the 3rd lens 23, can effectively it keep away
Sliding transfer is produced between the lens 23 of spring free 32 and the 3rd, further limitation lens, which are produced, moves radially.
Wherein, spring 32 can also select conical compression spring or butterfly spring, conical compression spring or butterfly bullet
The small-caliber end of spring is connected with spacer ring 31.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in the knowledge that the technical field those of ordinary skill possesses, this practicality can also not departed from
Various changes can be made on the premise of new objective.
