Description
Technical field
The utility model relates to a kind of Spring screws, relates in particular to the Spring screws of using on a kind of pile tube punching block.
Background technique
Early stage Spring screws, its structure are that a screw directly passes in conjunction with a spring, make the screw can be more firm when the screw lock with this, have obtained better screw lock effect.Because this Spring screws, spring directly is arranged on the screw, there is no any fixing means, so cause the screw lock deleterious because spring is crooked during screw lock easily, the time spent affects the connection of the upper and lower intermode of punching block on the pile tube punching block.
Existing a kind of Spring screws comprises screw rod 1, spring connecting sleeve 2, spring 3, fixed operating sleeve 4, nut 7 and nut sleeve 8, wherein screw rod comprises spiro rod cap, do not have threaded linkage section and the screwed section of being threaded, linkage section is positioned at spiro rod cap and is threaded intersegmental, linkage section and the intersegmental shaft shoulder that is provided with that is threaded, socket spring connecting sleeve on the linkage section of screw rod, spring and fixed operating sleeve, the spring connecting sleeve is close to spiro rod cap, the spring connecting sleeve be fixedly connected with the inner room linking springs, nut is threaded on the screw flight linkage section, nut overcoat connected nut cover, fixed operating sleeve is bolted to connection on the patrix 5 of punching block, and nut sleeve is welded on the counterdie 6 of punching block.Because the vibrations of the upper and lower intermode of punching block are very large, fixed operating sleeve is bolted on the patrix of punching block and gets loose easily, there is potential safety hazard, if fixed operating sleeve is welded on the patrix of punching block, the dismounting and change of this Spring screws difficulty, need the machine shop worker of specialty to be with oxygen and electric welding just can change during dismounting and change, very bother, the spring in this Spring screws can't disassemble alone, can't change the spring of internal damage, all change the waste resource, raise the cost.
The model utility content
The purpose of this utility model is to provide a kind of dismounting and changes the Spring screws that pile tube punching block is very easily used, solved the dismounting and change difficulty of Spring screws, and the spring in the Spring screws can't disassemble alone, can't change the spring of internal damage, all change the waste resource, the problem that raises the cost.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of Spring screws, comprise screw rod, the spring connecting sleeve, spring, fixedly be welded in the fixed muffle on the punching block patrix, nut and the nut sleeve that fixedly is welded on the punching block counterdie, screw rod comprises spiro rod cap, do not have threaded linkage section and the screwed section of being threaded, linkage section is positioned at spiro rod cap and is threaded intersegmental, linkage section and the intersegmental shaft shoulder that is provided with that is threaded, socket spring connecting sleeve and spring on the linkage section of described screw rod, nut is threaded on the section of being threaded, nut overcoat connected nut cover, linkage section and the intersegmental fixed muffle that is socketed with that is threaded, the spring connecting sleeve is close to spiro rod cap, fixed muffle is provided with shoulder hole, the aperture of the macropore of shoulder hole cooperates with spring, the aperture of the aperture of shoulder hole cooperates with the shaft shoulder, spring is fixedly connected between spring connecting sleeve and fixed muffle, spring one end socket spring connecting sleeve, the other end is socketed in the macropore of fixed muffle shoulder hole, the both sides of the inboard of the aperture of fixed muffle shoulder hole and macropore joint radially are provided with clamp spring hole, are plugged with jump ring in the clamp spring hole.The fixed muffle of this Spring screws and nut sleeve be the upper die and lower die of fixing welding pile tube punching block respectively, prevent that vibrations from coming off, the dismounting of this Spring screws, replacing need not electric welding and remove, only need to be with after taking out jump ring, i.e. detachable lower screw rod and the inner spring changed of needing behind the rotary screw, dismounting and change is convenient, only need the common laborer to use spanner to get final product dismounting and change, easy to use, save the labour force, reduce user cost.
As preferably, described jump ring is U-shaped, and the diameter of jump ring cooperates with the aperture of clamp spring hole.Make things convenient for the use of jump ring by this structure, be convenient to jump ring and take out and plug.
The beneficial effects of the utility model are: (1), this Spring screws only need to be with after taking out jump ring, i.e. detachable lower screw rod and the inner spring changed of needing behind the rotary screw, and dismounting and change is convenient; (2), only need the common laborer to use spanner to get final product dismounting and change, easy to use, save the labour force, reduce user cost.
