Description
Technical field
This utility model relates to a kind of drawing optical fibers UV cure lamp sealing device.
Background technology
The composition of optical fiber comprises 2 major parts, a bare fibre being made up of sandwich layer, covering, and two is the two layers of polymers coating outside naked fibre.Polymer coating outside bare fibre, be one can ultraviolet light irradiate under quick-setting colloid, after bare fibre is drawn out from fiber drawing furnace, after coating die, being wrapped in two-layer coating layer uniformly at its outer surface, now coating is in having the liquid condition of certain viscosity, moves quickly through ultra-violet curing lamp box afterwards, coating is solidified by the ultraviolet light of now lamp box release, thus forms finished product optical fiber.Under normal circumstances, ultraviolet curing lamp two or three is connected with each other, and forms one group.Each group of ultraviolet curing lamp runs through with a quartz glass tube, and optical fiber passes glass tubing center, completely cuts off with lamp box.It is passed through cooling wind in lamp box domestic demand ultraviolet lamp tube is cooled down, quartz glass tube domestic demand is passed through high pure nitrogen and promotes solidification, now being accomplished by the nitrogen in quartz glass tube and the cooling wind isolation in lamp box, this is accomplished by sealing quartz glass tube with lamp box mouth.
Sealing ring of the prior art usually easily glides because of installing not in place, thus causes sealing effectiveness bad, and the blast of lamp box is relatively big, affects the gas flowing in quartz glass tube, finally affects the solidification effect of fibre coating.
Utility model content
The purpose of this utility model is to provide a kind of drawing optical fibers UV cure lamp sealing device that can limit sealing ring slip.
For solving the problems referred to above, this utility model provides a kind of drawing optical fibers UV cure lamp sealing device, including the casing with hollow cavity surrounded by plate body, is provided with uviol lamp, and can be passed through cooling gas, it is characterised in that also include in described inner chamber:
-extend through the first through hole of two plate bodys and second through hole of described casing；
-also cross described first through hole, the second through hole, cavity volume and the hollow body that can be passed by ultraviolet light, described hollow body is is tightly connected with described first through hole and the second through hole, and the external part that described plate body can be stretched out at least provided with, also it is passed through solid gas in described hollow body；
-accommodating the first cover plate that described external part passes, described first cover plate is fixing with the outer surface of plate body one of them described to be connected；
-be arranged on described first cover plate, and accommodate the third through-hole that described hollow body passes；
-it being provided with the sealing ring accommodating the centre bore that described hollow body passes, its inwall of described sealing ring is tightly connected with described hollow body, and its outer wall is tightly connected with described third through-hole；
-it is fixed on described first cover plate, for the second cover plate being pressed on described cover plate by described sealing ring.
As further improvement of the utility model, described sealing ring be cross section be trapezoidal circulus, the end face that end face that described internal diameter of the seal ring is big is little compared with internal diameter is farther to the distance of described plate body, and described third through-hole directly coordinates the outer surface enabling to described sealing ring to be fitted in completely on the inwall of described third through-hole with described sealing ring outer surface.
As further improvement of the utility model, described hollow body is quartz ampoule.
As further improvement of the utility model, described sealing ring is fluorubber material.
The beneficial effects of the utility model are, this utility model arranges the first cover plate and the second cover plate, and sealing ring is positioned in the third through-hole of the first cover plate, and are pressed between cover plate and second cover plate of casing, it is possible to effectively solve the problem that sealing ring loosens slip.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein: 2-casing；4-the first through hole；6-the second through hole；8-hollow body；10-external part；12-the first cover plate；14-third through-hole；16-sealing ring；18-the second cover plate.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As it is shown in figure 1, this utility model includes the casing 2 with hollow cavity surrounded by plate body, described inner chamber is provided with uviol lamp, and cooling gas can be passed through, it is characterised in that also include:
-extend through first through hole 4 and second through hole 6 of two plate bodys of described casing 2；
-also cross described first through hole the 4, second through hole 6, cavity volume and the hollow body 8 that can be passed by ultraviolet light, described hollow body 8 is is tightly connected with described first through hole 4 and the second through hole 6, and the external part 10 that described plate body can be stretched out at least provided with, also it is passed through solid gas in described hollow body 8；
-accommodating the first cover plate 12 that described external part 10 passes, described first cover plate 12 is fixing with the outer surface of plate body one of them described to be connected；
-be arranged on described first cover plate 12, and accommodate the third through-hole 14 that described hollow body 8 passes；
-it being provided with the sealing ring 16 accommodating the centre bore that described hollow body 8 passes, described its inwall of sealing ring 16 is tightly connected with described hollow body 8, and its outer wall is tightly connected with described third through-hole 14；
-it is fixed on described first cover plate 12, for the second cover plate 18 being pressed on described cover plate by described sealing ring 16.
This utility model arranges the first cover plate 12 and the second cover plate 18, and sealing ring 16 is positioned in the third through-hole 14 of the first cover plate 12, and is pressed between cover plate and second cover plate 18 of casing 2, it is possible to effectively solves sealing ring 16 and loosens the problem slided.
As further improvement of the utility model, described sealing ring 16 is trapezoidal circulus for cross section, the end face that end face that described sealing ring 16 internal diameter is big is little compared with internal diameter is farther to the distance of described plate body, and described third through-hole 14 directly coordinates the outer surface enabling to described sealing ring 16 to be fitted in completely on the inwall of described third through-hole 14 with described sealing ring 16 outer surface.
