Abstract
The utility model discloses a screw protecting jacket comprising an intubation tube. One end of the intubation tube is closed, and a jack is arranged at the other end of the intubation tube; a nut casing is arranged on the jack; two ends of the nut casing are thorough, one end of the nut casing is connected with the jack, and the inner diameter of the nut casing at the connecting part is the same with the outer diameter of the intubation tube; and the inner diameter of the other end of the nut casing is the same with the outer diameter of a nut needing to be inserted and connected. The screw protecting jacket is reasonable in design and simple in structure; as the intubation tube and the nut casing are sheathed on a screw, dust or sand can be prevented from entering effectively, so that the jacket is convenient for cleaning; and simultaneously, as the screw is not easy to influence by blowing, raining and sunshine in the natural environment, the screw is not easy to subject to corrosion stains, so that the speed and the time for chemical reaction are reduced greatly, the service life of the screw is long, the frequency for replacing the screw is reduced, the cost is reduced, and the waste is reduced.
Description
Technical field the utility model belongs to the conventional fasteners technical field of tools, is specifically related to a kind of screw protecting cover.
The fastening screw of using of background technique existing technology has brought a lot of facilities for people's life, can screw be plugged on the object that will fix during use, and get final product with fastening on the nut.But there are many shortcomings in this screw: when to outdoor object, for example railway, machinery, building, bridge etc. carry out when fastening, and screw receives the influence of environment, can cause screw to be not easy to the cleaning dismounting at itself with some dusts or the grains of sand; Simultaneously, screw leaks in physical environment for a long time cruelly, can receive wind, drenches with rain, the influence of Exposure to Sunlight, generates the rust stain after causing screw to produce chemical reaction, causes its working life short, is unfavorable for the fastening effect of object; And the screw that need more renew frequently according to the rusting rate of screw can increase user cost like this, and waste is serious.
The purpose of summary of the invention the utility model provides a kind of screw protecting cover, and the material of screw protecting cover is plastics, and existing to be not easy to clear up dismounting, working life short and waste serious technical problem in order to overcome existing technology effectively.
The utility model screw protecting cover, it comprises intubate, the end sealing of said intubate, the other end is provided with a jack; Said jack is provided with the nut sleeve pipe; The two ends of said nut sleeve pipe are penetrating, and an end of nut sleeve pipe is connected with jack, and the internal diameter of the nut sleeve pipe of joint is identical with the external diameter of intubate; The other end internal diameter of said nut sleeve pipe is identical with the external diameter that needs the grafting nut.
For can with the screw of different model suit mutually, the internal diameter of the length of said intubate, internal diameter, jack and nut sleeve pipe can be produced according to the model of screw.
The utility model is reasonable in design, and is simple in structure, owing to be set with intubate and nut sleeve pipe on the screw, and the material of screw protecting cover is plastics, can effectively prevent the entering of the dust or the grains of sand, is convenient to clear up; Simultaneously, screw is not easy to receive wind in the physical environment, drenches with rain, the influence of Exposure to Sunlight, and just be not easy to produce and embroider stain, the speed and the time of having slowed down chemical reaction greatly, long service life, and the number of times of changing screw reduces, and cost reduces, and cuts the waste.
