Abstract
The utility model discloses a novel spring screw, and belongs to the technical field of fasteners. The novel spring screw comprises a threaded rod and a nut which is fixedly arranged at one end of the threaded rod, and threads are arranged at the other end of the threaded rod. The novel spring screw is characterized in that the threaded rod is sequentially provided with a check ring, a spring and a sleeve in a sleeved mode. The novel spring screw is simple in structure and reasonable in design. When the novel spring screw is tightly screwed, tight locking force is produced, and the phenomenon that the nut of a connecting piece is over-tight or loosens is avoided.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of novel spring screw.
Background technique
Screw is to utilize the inclined-plane circular rotating of object and physics and the mathematical principle of frictional force, the instrument of fastening implements parts by easy stages.After existing screw locking, long-time just easily loosening, what have is even too tight or too loose, affects fastening effect, and band is served trouble.
The model utility content
For the problem that prior art exists, the purpose of this utility model is to design the technological scheme that a kind of novel spring screw is provided.
Described a kind of novel spring screw comprises screw rod and the nut that is fixedly installed with screw rod one end, and the other end of described screw rod is provided with screw thread, it is characterized in that being socketed successively on described screw rod back-up ring, spring and sleeve are set.
Described a kind of novel spring screw is characterized in that described screw flight section and nut thread are equipped with.
Described a kind of novel spring screw is characterized in that described nut is fixedly installed in nut seat.
Described a kind of novel spring screw is characterized in that described screw rod and the nut structure that is formed in one.
Above-mentioned a kind of novel spring screw, simple in structure, reasonable in design, after screwing, Spring screws gives a certain amount of coupling mechanism force, and prevent the nut tension on connected piece or return loose phenomenon.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: the 1-nut; The 2-back-up ring; The 3-spring; The 4-screw rod; The 5-sleeve; The 6-nut.
Embodiment
Further illustrate the utility model below in conjunction with Figure of description.
As shown in the figure, a kind of novel spring screw comprises screw rod 4 and the nut 1 that is fixedly installed with screw rod 4 one ends, and screw rod 4 and nut 1 structure that is formed in one has increased the bulk strength of screw.The other end of screw rod 4 is provided with screw thread, and the screw section of screw rod 4 and nut 6 screw-thread fit settings, and nut 6 is fixedly installed in nut seat better guarantee the steadiness of screw rod 4 and nut 6.Be socketed successively on screw rod 4 back-up ring 2, spring 3 and sleeve 5 are set, after screwing spring 3, spring 3 gives respectively back-up ring 2 and a certain amount of coupling mechanism force of sleeve 5, prevents nut 6 tensions on connected piece or returns loose phenomenon.
Shown in the above and figure is only preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
