Abstract
The utility model discloses an elastic fixing structure of a lens, which comprises a lens barrel and the lens, wherein a lens accommodating groove is formed in the lens barrel, the lens is arranged in the lens accommodating groove, limiting protrusions are respectively arranged at two sides of the outer side of the lens accommodating groove in the lens barrel, spring limiting grooves with openings at the bottom ends are respectively formed in the limiting protrusions at two sides, limiting springs are arranged in the spring limiting grooves, the bottom ends of the limiting springs are respectively pressed at the two ends of the lens, and glue is poured in the spring limiting grooves. The elastic fixing structure of the lens adopts a combined fixing mode of glue and the V-shaped spring, and the lens is always clamped and installed in the lens barrel, so that the spring can adapt to high and low temperatures, and the installation stability of the lens in high and low temperature environments can be better ensured.
Description
Technical Field
The utility model relates to the technical field of installation and fixation of optical lenses, in particular to an elastic fixing structure of a lens.
Background
Lens fixing technology refers to firmly fixing a lens in a specific position in an optical device to ensure its stability and accuracy. In the fields of optical instruments, photographic equipment, microscopes and the like, a lens fixing technology plays a crucial role, and a traditional lens fixing mode is generally a sticking structure. As shown in fig. 1, the fixing method is to put the lens 2 into the lens barrel 1 at the position and apply glue on two sides of the lens for fixing. However, this fixing method has some drawbacks, such as unstable adhesion of the glue and easy loosening of the lens in high and low temperature environments. For some optical applications, such as high-power microscope or laser focusing system, it is necessary to ensure the stability of the lens in motion to ensure the imaging quality or the accuracy of laser focusing, the working quality is affected by the easy loosening of the lens, and the fixing mode of pure glue bonding cannot be satisfied.
Disclosure of utility model
In order to solve the technical problems, the utility model designs an elastic fixing structure of a lens.
The utility model adopts the following technical scheme:
The utility model provides an elastic fixation structure of lens, includes lens cone and lens, has seted up lens setting groove in the lens cone, lens setting inslot settles the lens, be provided with spacing arch in the lens cone respectively in lens setting groove outside both sides, set up respectively in the spacing arch on both sides at bottom open-ended spring spacing groove, spring spacing inslot settles spacing spring, and spacing spring bottom compresses tightly the both ends position at the lens respectively, and the pouring of spring spacing inslot has glue.
Preferably, the limit spring is a V-shaped spring. The limiting springs are convenient to be placed into the spring limiting grooves and clamped at two ends of the lens.
Preferably, the outer side end of the spring limit groove is open. The installation of the limiting spring in the spring limiting groove is convenient.
Preferably, a relief hole is formed at the corner of the joint of the lens in the lens cone and the lens cone. The lens is convenient to install.
Preferably, a gap is reserved between the limiting protrusion and the lens. The lens is convenient to install.
The beneficial effects of the utility model are as follows: the elastic fixing structure of the lens adopts a combined fixing mode of glue and the V-shaped spring, and the lens is always clamped and installed in the lens barrel, so that the spring can adapt to high and low temperatures, and the installation stability of the lens in high and low temperature environments can be better ensured.

FIG. 3 is a front view of the present utility model;
In the figure: 1. the lens cone, 2, the lens, 3, spacing protruding, 4, spring spacing groove, 5, spacing spring, 6, hole of stepping down.
Detailed Description
The technical scheme of the utility model is further specifically described by the following specific embodiments with reference to the accompanying drawings:
examples: as shown in fig. 2 and 3, an elastic fixing structure of a lens comprises a lens barrel 1 and a lens 2, wherein a lens placement groove is formed in the lens barrel, the lens is placed in the lens placement groove, limiting protrusions 3 are respectively arranged on two sides of the outer side of the lens placement groove in the lens barrel, spring limiting grooves 4 with bottom openings are respectively formed in the limiting protrusions on two sides of the lens placement groove, limiting springs 5 are arranged in the spring limiting grooves, the bottom ends of the limiting springs are respectively pressed at two end positions of the lens, and glue is poured in the spring limiting grooves.
The limit spring is a V-shaped spring. The outer side end of the spring limit groove is opened. The corner of the lens in the lens cone, which is connected with the lens cone, is provided with a abdication hole 6. A gap is reserved between the limiting bulge and the lens.
When the elastic fixing structure of the lens is installed, the lens is firstly placed in the lens placement position in the lens barrel, then the V-shaped spring is inserted in the spring limiting groove, so that the V-shaped spring compresses the two ends of the lens, and glue is filled in the spring limiting groove to prevent the V-shaped spring from being ejected.
The elastic fixing structure of the lens adopts a combined fixing mode of glue and the V-shaped spring, and the lens is always clamped and installed in the lens barrel, so that the spring can adapt to high and low temperatures, and the installation stability of the lens in high and low temperature environments can be better ensured.
The above-described embodiment is only a preferred embodiment of the present utility model, and is not limited in any way, and other variations and modifications may be made without departing from the technical aspects set forth in the claims.
