Technical field
The utility model relates to laser tube field, in particular to a kind of laser tube rear lens.
Background technique
Current existing laser tube is typically employed in glass tube end and installs two flanges, and rear lens is adhered on flange,
In order to adjust laser by adjusting lens angle, usually using six bolt assemblies by two flanged joints one, and in two methods
One copper sheet is set between orchid；Lens angle is adjusted by the way that adjusting bolt assembly is elasticity, this mode has two:
1, in use, being adjusted by screwing or loosening six bolt assemblies to laser；When screwing bolts component, two flanges it
Between oppress copper sheet, deform copper sheet, to make lens tilt, reach adjustment purpose；After being squeezed deformation due to copper sheet, if
The form adjustment lens angle for loosening bolt assembly was communicated again, then the sealing between copper sheet and flange can be destroyed, and there is leakage
Gas phenomenon causes laser tube service life low.2, since there are some problems for the connection structure of two flanges and copper sheet, laser is caused
The power that pipe issues laser fluctuates in a certain range, this will cause adverse effect to the use of laser, therefore, it is proposed that one
Kind laser tube rear lens.
Patent No. CN201420452640.1 discloses a kind of laser tube rear lens.The utility model provides a kind of hair
Laser is stablized out, and the laser tube rear lens of gas leak phenomenon will not occur for long service life.The utility model includes column camera lens
Body, it is characterised in that: the outer surface of column lens body is provided with electrode hole；Through-hole is provided in column camera lens body；The column
It is provided with cyclic annular adjustment tank in the middle part of camera lens external surface, is provided at least three conical screw holes at the ring-type adjustment tank, it should
The shortcomings that utility model are as follows: 1, by the way of opening up threaded hole on column lens body, it is micro-adjusted, this adjustment mode
It is easily damaged lens body, 2, do not plate optical coating on camera lens, the reflection and transmittance on camera lens surface cannot be changed well
Energy.
Utility model content
The main purpose of the utility model is to provide a kind of laser tube rear lens, can effectively solve in background technique
Problem.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of laser tube rear lens, including electrode boss, the second column lens body and eyeglass boss, in the electrode boss
Side offers through-hole, and the through-hole inside left-end offers slot electrode, is connected with the first column camera lens on the left of the electrode boss
Body, the first column lens body left side are equipped with the second column lens body, the first column lens body and the second prismatic mirror
It is respectively welded the first link block and the second link block on front side of head body, is respectively mounted inside first link block and the second link block
There is fixing bolt, offers the first bolt hole and the second bolt hole, institute respectively on the inside of first link block and the second link block
It states the first column lens body rear side left end and the second column lens body is connected with by shaft, connect on the left of the second column lens body
It is connected to eyeglass boss.
Further, laser lens are installed on the inside of the eyeglass boss, the laser lens surface is coated with optical coating.
Further, top offers electrode hole on front side of the first column lens body.
Compared with prior art, the utility model has the following beneficial effects: by being equipped with the first column lens body and the
The first link block, the second link block and shaft on two column lens bodies, can allow the Light deformation of camera lens to be adjusted in outside,
When eliminating and open up bolt hole inside column camera lens body and be adjusted, while also avoiding adjusting the damage of Light deformation bolt hole,
It needs to replace entire column lens body, is conducive to more practical use laser tube rear lens, by being equipped with laser mirror
The optical coating of on piece, thus it is possible to vary the transmission and reflection characteristic of material surface can be improved the reflection and transmission of laser lens
Performance is conducive to more practical use laser tube rear lens.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs 1-4, a kind of laser tube rear lens, including electrode boss 1, the second column lens body 9 and eyeglass boss
10, through-hole 2 is offered on the inside of the electrode boss 1, and 2 inside left-end of through-hole offers slot electrode 3, the electrode boss 1
Left side is connected with the first column lens body 4, is equipped with the second column lens body 9 on the left of the first column lens body 4, and described
