Abstract
The utility model discloses a top sealing structure of a light pipe, which comprises a light pipe, a lighting cover and a rainproof cover, wherein the outer wall of the top of the light pipe is sleeved with the rainproof cover via a mounting opening in the top of the rainproof cover; an inner sealing ring is arranged between the wall of the mounting opening of the rainproof cover and the outer wall of the top of the light pipe; a horizontal sealing ring sealed at the top of a gap is connected with the top of the inner sealing ring; the upper part of the rainproof cover is covered with the lighting cover via the cover opening in the bottom of the lighting cover; an outer sealing ring is arranged between the wall of the cover opening of the lighting cover and the side wall of the rainproof cover. The top sealing structure of the light pipe can effectively improve the sealing performance and combination tightness of the light pipe, the rainproof cover and the lighting cover.
Description
Technical field
the utility model relates to the photoconductive tube field, is specially a kind of photoconductive tube top seal structure.
Background technology
Photoconductive tube is requisite structure in light-guiding illuminating device, and it is hollow tubular, utilize inwall rete will from the light of photoconductive tube one end incident after Multi reflection from the outgoing of the photoconductive tube other end, there is higher light transmissioning efficiency.Its mouth of pipe place, top operated by rotary motion of photoconductive tube is set with rain cover, dome skylight is set on rain cover, between prior art photoconductive tube, rain cover, dome skylight, the junction sealing is poor, in conjunction with not tight, easily enter rainwater or other impurity in photoconductive tube, cause photoconductive tube inwall vulnerable to pollution, affect the light laser propagation effect of photoconductive tube.
The utility model content
The purpose of this utility model is to provide a kind of photoconductive tube top seal structure, to solve the poor problem of sealing between prior art photoconductive tube, dome skylight, rain cover.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of photoconductive tube top seal structure, include photoconductive tube, dome skylight, rain cover, it is characterized in that: described rain cover top forms installing port, rain cover is enclosed within on the photoconductive tube top exterior walls by its installing port, rain cover installing port mouth wall and photoconductive tube top sidewall are fixed as one by screw, and be provided with inner seal ring between rain cover installing port mouth wall and photoconductive tube top exterior walls, described inner seal ring top is connected with the horizontal seal circle at horizontal seal top, gap between rain cover installing port mouth wall and photoconductive tube top exterior walls, described dome skylight bottom is made as cover mouthful, dome skylight covers mouth mask on rain cover top by it, between dome skylight cover mouth mouth wall and rain cover sidewall, by screw, be fixed as one, and be provided with exterior seal ring between dome skylight cover mouth mouth wall and rain cover sidewall.
Described a kind of photoconductive tube top seal structure is characterized in that: described rain cover installing port mouth wall forms extension to downward-extension, and described photoconductive tube top sidewall is fixed as one by screw and rain cover installing port mouth wall extension.
The utility model seals up gap, junction between rain cover and photoconductive tube by inner seal ring, and by the horizontal seal circle further between rain cover and photoconductive tube top, gap, junction sealed, between outer dome skylight and rain cover, by exterior seal ring, sealed simultaneously, utilize this structure can effectively improve the sealing property between photoconductive tube, rain cover, dome skylight, and improve between the three in conjunction with compactness.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1.A kind of photoconductive tube top seal structure, include photoconductive tube 1, dome skylight 2, rain cover 3, rain cover 3 tops form installing port, rain cover 3 is enclosed within on photoconductive tube 1 top exterior walls by its installing port, rain cover 3 installing port mouth walls and photoconductive tube 1 top sidewall are fixed as one by screw 4, and be provided with inner seal ring 5 between rain cover 3 installing port mouth walls and photoconductive tube 1 top exterior walls, inner seal ring 5 tops are connected with the horizontal seal circle 6 at horizontal seal top, gap between rain cover 3 installing port mouth walls and photoconductive tube 1 top exterior walls, dome skylight 2 bottoms are made as cover mouthful, dome skylight 2 covers mouth mask on rain cover 3 tops by it, between dome skylight 2 covers mouthful mouthful wall and rain cover 3 sidewalls, by screw 7, be fixed as one, and be provided with exterior seal ring 8 between dome skylight 2 covers mouthful mouthful wall and rain cover 3 sidewalls.
Rain cover 3 installing port mouth walls form extension 9 to downward-extension, and photoconductive tube 1 top sidewall is fixed as one by screw 4 and rain cover 3 installing port mouth wall extensions 9.
