Abstract
The utility model discloses a spring screw used on a pipe pile steel die. A sleeve barrel protective sleeve is arranged on the spring screw and used for bearing wear to a fixing sleeve barrel when a screw rod is tightly screwed. The sleeve barrel protective sleeve is convenient to replace so that service life of the spring screw is prolonged, use cost is saved, production benefits are improved, and the problems that a fixing sleeve barrel on an existing spring screw is fixedly welded on an upper die of the steel die and can not be replaced, the wear to the fixing sleeve barrel is severe when the screw rod is tightly screwed, and the service life of a whole product is shortened are solved.
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, the spring connecting sleeve, spring, fixed muffle, nut and nut sleeve, 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 muffle, the spring connecting sleeve is close to spiro rod cap, linking springs between spring connecting sleeve and fixed muffle, nut is threaded on the screw flight linkage section, nut overcoat connected nut cover, fixed muffle fixedly is welded to connect on the patrix of punching block, and nut sleeve is welded on the counterdie of punching block.Because fixed muffle fixedly is welded to connect on the patrix of punching block and can't changes, and screw rod will to the fixed muffle serious wear, reduce the working life of whole product when tightening.
The model utility content
The purpose of this utility model is to provide the Spring screws of using on a kind of pile tube punching block, the fixed muffle that has solved on the existing Spring screws fixedly is welded to connect on the patrix of punching block and can't changes, and when tightening, screw rod will to the fixed muffle serious wear, reduce the problem in the working life of whole product.
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 to connect the fixed muffle on the patrix of punching block, nut and fixedly be welded in nut sleeve on the counterdie of punching block, 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, socket spring connecting sleeve on the linkage section of screw rod, spring and fixed muffle, the spring connecting sleeve is close to spiro rod cap, linking springs between spring connecting sleeve and fixed muffle, nut is threaded on the screw flight linkage section, nut overcoat connected nut cover, spring place between spring connecting sleeve and fixed muffle is socketed with the sleeve sheath that the end caves inward, and the concave face of the end face of fixed muffle and sleeve sheath cooperates.This Spring screws is by arranging the sleeve sheath, will wear and tear to fixed muffle when making it bear screw rod and tighten, and the sleeve sheath changes conveniently, so just greatly promoted working life of Spring screws to save user cost, the raising productivity effect.
As preferably, described fixed muffle is provided with shoulder hole, and the aperture of the macropore of shoulder hole cooperates with spring.Be convenient to spring position fixing in this Spring screws by this structure.
The beneficial effects of the utility model are: this Spring screws is by arranging the sleeve sheath, to wear and tear to fixed muffle when making it bear screw rod and tighten, and the sleeve sheath changes conveniently, so just greatly promoted working life of Spring screws, save user cost, improve productivity effect.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation of screw rod in the utility model;
Among the figure: 1, screw rod, 2, the spring connecting sleeve, 3, spring, 4, the sleeve sheath, 5, fixed muffle, 6, the punching block patrix, 7, the punching block counterdie, 8, nut, 9, nut sleeve, 10, spiro rod cap, 11, linkage section, 12, the section of being threaded.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figures 1 and 2, a kind of Spring screws, comprise screw rod 1, spring connecting sleeve 2, spring 3, fixedly be welded to connect the fixed muffle 5 on punching block patrix 6, nut 8 and the nut sleeve 9 that fixedly is welded on the punching block counterdie 7, wherein screw rod comprises spiro rod cap 10, do not have threaded linkage section 11 and the screwed section of being threaded 12, linkage section is positioned at spiro rod cap and is threaded intersegmental, socket spring connecting sleeve on the linkage section of screw rod, spring and fixed muffle, the spring connecting sleeve is close to spiro rod cap, linking springs between spring connecting sleeve and fixed muffle, nut is threaded on the screw flight linkage section, nut overcoat connected nut cover, spring place between spring connecting sleeve and fixed muffle is socketed with the sleeve sheath 4 that the end caves inward, the concave face of the end face of fixed muffle and sleeve sheath cooperates, fixed muffle is provided with shoulder hole, and the aperture of the macropore of shoulder hole cooperates with spring.
This Spring screws is by arranging the sleeve sheath, will wear and tear to fixed muffle when making it bear screw rod and tighten, and the sleeve sheath changes conveniently, so just greatly promoted working life of Spring screws to save user cost, the raising productivity effect.
Above-described embodiment is a kind of better scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technological scheme that claim puts down in writing.
