Abstract
The utility model discloses a detachable screw, its characterized in that: including screwhead, screw body and spiral shell screw tail, screw body's one side and screwhead carry out swing joint through interior external screw thread, screw body's opposite side and spiral shell screw tail carry out swing joint through interior external screw thread. The utility model has the advantages of: the utility model discloses a screwhead and spiral shell screw tail can realize dismantling, in case when screwhead or spiral shell screw tail damage, can realize the dismantlement and the installation at impaired position through external screw thread in the rotating, have practiced thrift manufacturing cost greatly, have avoided unnecessary to waste.
Description
Technical field
This utility model belongs to machinery spare and accessory parts field, is specifically related to a kind of detachable screw.
Background technology
At present, the screw during society is manufacturing and using has many kinds, but is broadly divided into two classes.One class is normal screws nail, for its structure this screwed screw rod and screw tip be provided with for confining location difform nut composition, the screw of this structure is to fasten with it be positioned together by being threaded in connected securing member and by nut, another connecting securing member on screw rod, thus realizing being linked together by two pieces device of task, although the screw of this structure can realize being linked together by two kinds of devices of task, but owing to the screw of this structure is single by the screw thread on screw and by mating connection with the screw thread on connected piece, this screw easily loosens thus producing adverse consequences, this is the unsurmountable defect that this kind of screw exists.Another kind of lock screw nail, its structure is increase screw thread on nut, and upper fixation is locked on lower fixture by double thread, thus having feature reliable and stable, that anti-shake performance is strong.But, the screw tip of this common two classes screw and screw nail tail are impaired comparatively serious, at this time, are typically directly directly abandoned by whole screw.
Utility model content
The purpose of this utility model is in that for the deficiencies in the prior art, now provides and a kind of can change damaged parts, realizes the detachable screw of recycled for multiple times.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of detachable screw, its innovative point is in that: include head of screw, screw body and screw tail, the side of described screw body is flexibly connected by internal and external threads with head of screw, and the opposite side of described screw body is flexibly connected by internal and external threads with screw tail.
Further, described head of screw includes screw tip and connector a, and described screw tip and connector a are formed in one, and the structure of described screw tip is cone, and the structure of described connector a is cylinder, and described cylinder connector a surface is provided with external screw thread.
Further, described screw tail includes connector b and screw nail tail, described connector b and screw nail tail and is formed in one, and described connector b is cylindrical structure, and the connector b surface of described cylindrical structure is provided with external screw thread.
Further, the structure of described screw body is cylinder, the both sides of described cylinder screw body are designed with a cylinder groove, the length of described cylinder groove is consistent with the length of connector, the inner surface of described cylinder groove is provided with female thread, and described female thread matches with the external screw thread on connector surface use.
The beneficial effects of the utility model are as follows: head of screw of the present utility model and screw tail can realize dismounting, damage once head of screw or screw tail, it is possible to by turn internal and external threads, it is achieved the dismounting of damaged part and installation, it is greatly saved production cost, it is to avoid unnecessary waste.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
It is illustrated in figure 1 structural representation of the present utility model, a kind of detachable screw, including head of screw, screw body 3 and screw tail, the side of screw body 3 is flexibly connected by internal and external threads with head of screw, and the opposite side of screw body 3 is flexibly connected by internal and external threads with screw tail.
Head of screw includes screw tip 1 and connector a11, and screw tip 1 and connector a11 are formed in one, and the structure of screw tip 1 is cone, and the structure of connector a11 is cylinder, and cylinder connector a11 surface is provided with external screw thread.
Screw tail includes connector b31 and screw nail tail 3, connector b31 and screw nail tail 3 and is formed in one, and connector b31 is cylindrical structure, and the connector b31 surface of cylindrical structure is provided with external screw thread.
The structure of screw body 2 is cylinder, the both sides of cylinder screw body 2 are designed with a cylinder groove, the length of cylinder groove is consistent with the length of connector, and the inner surface of cylinder groove is provided with female thread, and female thread matches with the external screw thread on connector surface use.
Head of screw of the present utility model and screw tail can realize dismounting, damage once head of screw or screw tail, it is possible to by turn internal and external threads, it is achieved the dismounting of damaged part and installation, be greatly saved production cost, it is to avoid unnecessary waste.
Above-described embodiment is preferred embodiment of the present utility model; it it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, be regarded as falling within the scope of the rights protection of this utility model patent.
