Abstract
The utility model discloses a retractable dust cover which comprises a base, a middle tube, an upper tube and a lower tube, wherein the middle tube is formed by a plurality of round tubes in sleeved connection and is positioned between the upper tube and the lower tube, the sizes of the round tubes are matched, and the lower tube is connected with the base. The retractable dust cover is made of steel and retractable, thereby avoiding the defeats that a dust cover made of canvas is oil-impregnated, out of shape after contacting with oil and easy to be damaged so as to lead to oil leakage, dust retention on surfaces and breakage. The retractable dust cover has the advantages of being retractable, not oil-impregnated, never damaged and dust-proof. After a trial, the retractable dust cover solves the problem of oil leakage once and for all, and simultaneously a whole screw-down screw rod is very clean and not possible to be out of shape and damaged without the pollution of oil, thereby lubricating oil consumption is decreased by about 400 liters every month after the dust cover is used.
Description
Technical field
The utility model relates to a kind of dust guard, especially a kind ofly is used for the flexible dust cover of steel that big mill is depressed leading screw.
Background technology
Big mill is depressed the dust cover that leading screw adopts the canvas material, by built-in steel wire support ring, be sewn into annular ripple, prevent dust, but depressing because of blooming mill has lubricating oil and needs frequently flexible up and down in the leading screw, and canvas dust cover oil impregnate, meet the distortion of oil back, cracky, cause drawbacks such as leakage of oil, surperficial laying dust, breakage.
The utility model content
The technical problems to be solved in the utility model provides a kind of flexible dust cover that is difficult for oil impregnate, breakage.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it is made of base, intervalve and upper pipes and lower end pipe; Intervalve is socketed to form by the pipe that some sizes cooperatively interact, and between upper pipes and lower end pipe; The lower end pipe is connected with base.
The further technical scheme of the present invention: each pipe diameter of described intervalve increases progressively from top to bottom successively; The two ends of each pipe are equipped with the edge, and wherein the upper edge is interior edge, and the lower edge is the outer; In the two adjacent arbitrarily pipes, match with the upper edge of hypomere pipe in the lower edge of epimere pipe.
Adopt the beneficial effect that technique scheme produced to be: the present invention is the extension type design of steel, thereby has stopped dust cover oil impregnate, the back distortion of chance oil, the cracky of canvas material, causes drawbacks such as leakage of oil, surperficial laying dust, breakage.Advantages such as it is scalable, oil-tight, never damaged, dustproof that the present invention has; Through on probation, after using, the present invention effected a radical cure the leakage of oil problem, and simultaneously because of the whole leading screw of depressing of pollution that does not have oil extremely cleans, the damaged possibility of distortion does not use the back to save the about 400L of lubrication oil consumption in every month.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
This flexible dust cover, it is made of base 7, intervalve 3 and upper pipes 1 and lower end pipe 6; Base 7 is used for being connected and having oil return opening with the anti-card oil cylinder that rolls, and is used for oil return.Intervalve 3 is made up of the pipe socket that some sizes cooperatively interact, and it is little to get intervalve topmost, and the next one can be set to an outside slightly greatly; The two ends of each pipe are equipped with the edge, and wherein upper edge 4 is interior edge, and lower edge 5 is the outer; Match with the upper edge 4 of hypomere pipe in the lower edge 5 of epimere pipe, the hypomere pipe is used to sling.Upper pipes 1 is connected and fixed whole flexible dust cover with frame, and lower end pipe 6 is connected with base 7 and is used for oil sealing and fixes the dust cover that stretches.
This flexible dust cover in use, when depressing leading screw 2 declines, base 7 descends thereupon, begin mutual stretching, extension from the preceding paragraph intervalve, all the other intervalves descend with base, snap into the second joint intervalve lower edge up to the preceding paragraph intervalve, the second joint intervalve is stretched over and blocks the 3rd joint intervalve lower edge then, analogizes as scheduled up to whole stretching, extensions.When depressing leading screw and rise, begin to shrink from next joint intervalve, the second joint intervalve above all entangling, the second joint intervalve is set to top the 3rd joint intervalve more then, so analogizes up to whole contractions.
Claims (2)
1. flexible dust cover, it is characterized in that: it is made of base, intervalve and upper pipes and lower end pipe; Intervalve is socketed to form by the pipe that some sizes cooperatively interact, and between upper pipes and lower end pipe; The lower end pipe is connected with base.
2. flexible dust cover according to claim 1 is characterized in that: each pipe diameter of described intervalve increases progressively from top to bottom successively; The two ends of each pipe are equipped with the edge, and wherein the upper edge is interior edge, and the lower edge is the outer; In the two adjacent arbitrarily pipes, match with the upper edge of hypomere pipe in the lower edge of epimere pipe.
