Embodiment 1
Be a kind of embodiment-cover of dust 100 of the utility model dust cover for hose connector as depicted in figs. 1 and 2.Cover of dust 100 comprises dustproof lid 110 and is symmetricly set on the support arm 120 of dustproof lid both sides, cranks arm 130, under the preferred situation, and the dustproof lid structure that is formed in one.The lower surface of dustproof lid 110 be provided with the adaptor union mouth on the groove 111 that is complementary of the self sealss packing ring that is provided with, the groove top of groove 111 is arch.The support arm 120 of dustproof lid 110 1 side settings comprises the support arm bottom 121 of extending along dustproof lid 110, be positioned at the free end of support arm bottom 121, perpendicular to the support arm top 122 of dustproof lid, support arm top 122 is used to probe in the sector grooves, the upper end on support arm top 122 is used to withstand the surface down of sector grooves, downward application force is provided for dustproof lid 110 from this side.Cranking arm of dustproof lid 100 opposite side settings 130 be used for fan-shaped flange on the snap-on connector, cranks arm 130 for being made up of top 131, sidepiece 132 and bottom 133
Type, under the preferred situation, the sidepiece 132 of cranking arm slightly tilts to dustproof lid 110, and the bottom 133 of cranking arm also slightly tilts to dustproof lid 110, to strengthen the strength of buckle.The upper surface bilateral symmetry on top 131 of cranking arm is provided with two reinforced ribs 134 that extended towards sidepiece 132 directions of cranking arm by dustproof lid 110, and the downward application force that fan-shaped flange lower surface is provided better passes to dustproof lid 110 uniformly.The upper surface of bottom 133 of cranking arm is provided with arc groove with the fan-shaped flange lower surface curved flanges 135 that is complementary, with curved flanges 135 precession arc groove inside, when cranking arm the degree of packing of the fan-shaped flange of 130 buckles, also play located lateral effect to dustproof lid 110 with raising.
Preferably, the crank arm junction 136 of top 131 and the sidepiece 132 of cranking arm and the junction 137 of crank arm sidepiece 132 and the bottom 133 of cranking arm is one section circular arc, and the center of circle of described circular arc 136 and 137 and dustproof lid 110 are positioned at the homonymy of described circular arc 136 and 137, correspondingly, crank arm left and right two surfaces of sidepiece 132 for along the cambered surface of circular arc 136,137, its purpose is, from the mechanics angle, make and the support that top 131, sidepiece 132 and the bottom 133 crank arm each other can be more stable under stressed situation, to be difficult for bending.
Same reason, support arm bottom 121 also is one section circular arc with the junction 124 on support arm top 122, and the center of circle of described circular arc 124 and described dustproof lid 110 are positioned at the homonymy of described circular arc 124, and left and right two surfaces on support arm top 122 also are the cambered surface along circular arc 124.
Embodiment 2
Be the another kind of embodiment-cover of dust 200 of the utility model dust cover for hose connector as shown in Figure 3 and Figure 4.Compare with embodiment 1, the difference of present embodiment is, when the sector grooves of adaptor union when the adaptor union mouth is relatively far away, the support arm of being made up of support arm bottom 121 and support arm top 122 120 among the embodiment 1 is difficult to enter sector grooves inside, therefore the support arm 220 of present embodiment comprises the support arm bottom 221 of extending along dustproof lid 210, support arm top 222 perpendicular to dustproof lid 210, and the support arm connecting portion 223 towards the sector grooves inner inclination that is used to connect support arm bottom 221 and support arm top 222, make support arm top 222 can further probe into sector grooves inside, the upper end on support arm top 222 is easy to withstand the surface down of sector grooves.
Correspondingly, support arm bottom 221 is one section circular arc with the junction 225 of support arm connecting portion 223 and the junction 226 of support arm top 222 and support arm connecting portion 223, and the center of circle of described circular arc 225 and 226 and described dustproof lid 210 are positioned at the homonymy of described circular arc 225 and 226, and left and right two surfaces of support arm top 222 and support arm connecting portion 223 are the cambered surface along circular arc 225 and 226.
Fig. 5 is used for the use scheme drawing of adaptor union 300 for cover of dust 200.During cap seal, earlier with the self sealss packing ring 301 on the communication port of groove 211 alignment connectors 300, circumference rotation cover of dust 200 along the self sealss packing ring, in the groove with support arm 220 precession sector grooves 302, the lower surface of sector grooves 302 is withstood in the upper end on support arm top 222, simultaneously in the arc groove 304 with fan-shaped flange 303 lower surfaces of curved flanges 235 precessions, fan-shaped flange 303 enters and crank arm 230
In the type track, making cranks arm 230 closely fastens with fan-shaped flange 303.At this moment, the surface down of sector grooves 302 provides downward application force by the upper end on support arm top 222 to dustproof lid 210 1 sides, the lower surface of fan-shaped flange 303 provides downward application force equally by the opposite side of the 230 pairs of dustproof lids 210 of cranking arm, and makes dustproof lid 210 in vertically firm being fixed on the hose coupling.The located lateral effect to dustproof lid 210 has been played in crank arm arc groove chimeric of curved flanges 235 and fan-shaped flange lower surface of upper surface of bottom 233.
In addition, dust cover for hose connector of the present utility model can adopt any material manufacturing, but occasion in conjunction with the cover of dust practical application, prevent in transportation that mainly foreign matter from entering the inner air flue of hose coupling assembly, the preferred plastic material that adopts, obviously it is low than the metal material cost, moulding is easy, easy to process, productive rate is high.In plastic material, preferably adopt the polyethylene material, it is outstanding than other plastic material environmental-protecting performances, resistance to low temperature is good.Certainly, in conjunction with concrete actual conditions, it is also conceivable that the plastic material of preferred other kinds of employing.
