The effect of dust seal.
Utility model content
The purpose of this utility model is the combined sealing structure for providing dust cap and sealing ring, to solve above-mentioned background skill
Groove, mostly filled circles loop configuration are not provided with the inside of the supporting sealing ring of dust cap proposed in art, thus can not be with needing
Dust-proof tubular equipment eck suits, it is impossible to the problem of reaching the effect of dust seal.
To achieve the above object, the utility model provides following technical scheme：The combination sealing knot of dust cap and sealing ring
Structure, including dust-proof block, the middle position of the dust-proof block are provided with dust cap hook installing plate, the dust cap hook
Dust cap hook is provided with installing plate, the dust cap main body vertical with dust-proof block is provided with above the dust-proof block,
The dust cap main body is internally provided with the supporting o-ring groove of dust cap, the inside of the supporting o-ring groove of dust cap
The supporting sealing ring of dust cap is provided with, dust cap internal thread is provided with the inner surface wall of the dust cap main body.
Preferably, the dust cap main body is screwed with dust guard pollution abatement equipment by dust cap internal thread is connected.
Preferably, the inner side of the supporting sealing ring of the dust cap is set fluted.
Preferably, the dust cap main body is hollow cylindrical structure.
Preferably, the dust cap hook is cirque structure.
The utility model compared with prior art, has the advantages that：
(1) the utility model dust cap main body is screwed by dust cap internal thread with dust guard pollution abatement equipment and is connected, can be by anti-
Dirt lid internal thread makes dust cap main body be closely connected with dust guard pollution abatement equipment, lift-off seal effect.
(2) inner side of the supporting sealing ring of the utility model dust cap is set fluted, recessed in the supporting sealing ring of dust cap
Groove, to needing dust-proof tubular equipment to seal, reaches the effect of dust seal with needing dust-proof tubular equipment eck to suit.
(3) the utility model dust cap main body is hollow cylindrical structure, greatlys save making material, is provided using saving
Source.
(4) the utility model dust cap hook is cirque structure, can link up with one end of cotton rope through dust cap, and with
Dust cap hook is fixed, and the other end of cotton rope, which is fixed on, to be needed on dust-proof tubular equipment, when without using dust cap, is prevented
Dirt losing of cover.
