Abstract
The utility model discloses a kind of dowel screw dismantling device of improvement, comprise screw, two-way nut, dowel screw, open slot, screw, convergence slot, shell fragment.Feature is that two-way nut has open slot in installation dowel screw end, screw extremely communicates with convergence slot through open slot, the other end of two-way nut has screw mounting screw, screw, dowel screw be fit into two-way nut after its top merge in convergence slot, open slot is divided into shell fragment and former two-way nut body two parts two-way nut, is formed on two-way nut and has elastic piece structure.Screw is standard component, and purposes scope is wide, highly versatile, rigid structure, changes into elasticity and connects, in conjunction with great efforts.
Description
Technical field
The utility model relates to dismantling device, the dowel screw dismantling device of particularly a kind of improvement.
Background technology
In present machinery industry, part, due to space reasons, uses dowel screw to connect locking, and dowel screw limited length, does not process and uses spanner space to screw dowel screw position, only tight with hand-screw or screw with common dowel screw dismantling device.Common dowel screw dismantling device basic structure is: screw and two-way nut combinations for together with.Two-way nut is the dowel screw self-control screwed needed for basis, and screw uses General purpose screw.
Summary of the invention
The purpose of this utility model is provide one can overcome common dowel screw dismantling device structure and manufacture simple, common dowel screw dismantling device screws in dowel screw, with spanner, screw screw-in is held out against dowel screw end face again, effect is the relative motion stoping two-way nut and dowel screw, but when dowel screw is dismantled or installs more firm, screw and dowel screw end face tightening power need quite to strengthen, and could stop the relative motion of two-way nut and dowel screw, this operation is very inconvenient.Finally rotate two-way nut with spanner and realize the structure of mounting or dismounting dowel screw simply, easy to manufacture, easy to install, the dowel screw dismantling device of a kind of improvement that the scope of application is wide.
Technical solution of the present utility model is such, a kind of dowel screw dismantling device of improvement, comprise screw, two-way nut, dowel screw, open slot, screw, convergence slot, shell fragment, it is characterized in that two-way nut (2) has open slot (4) in installation dowel screw (3) end, screw (5) extremely communicates with convergence slot (6) through open slot (4), the other end of two-way nut (2) has screw mounting screw (1), screw (1), dowel screw (3) is fit into two-way nut (2) and merges in convergence slot (6) in its top afterwards, open slot (4) is divided into shell fragment (7) and two-way nut (2) body two parts two-way nut (2), be formed on two-way nut (2) and have elastic piece structure.
The open slot (4) of two-way nut (2) be three open-minded, one side connects at two-way nut (2) body.
Compared with prior art, the beneficial effects of the utility model are: the two-way nut of the dowel screw dismantling device of improvement increases processing open slot, and structure is equally simple, is also easy to processing.Two-way nut is under smaller tensile force effect, two-way nut notch aperture can be made to become large, the pitch of this end screw thread is changed, no longer the same with dowel screw pitch, pitch is caused to conjugate the relative motion meeting and stop two-way nut and dowel screw, this more convenient operation, does not affect by screw and dowel screw relative sliding.

Reference numeral: screw (1), two-way nut (2), dowel screw (3), open slot (4), screw (5), convergence slot (6), shell fragment (7).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
The chief component of the dowel screw dismantling device of the utility model improvement by: screw (1) and two-way nut (2) forms, but two-way nut (2) the increase processing open slot (4) of the dowel screw dismantling device improved.Two-way nut (2) open slot (4) that end of the dowel screw dismantling device of improvement screws in dowel screw (3), with spanner screw (1) screwed in from two-way nut (2) other end again and hold out against dowel screw (3) end face (see accompanying drawing 3), and the part that open slot (4) hold can be deformed under a stretching force, thus the pitch generation Flexible change of the partial threads that open slot (4) is held, reach and stop two-way nut (2) and dowel screw (3) relative motion in convergence slot (6), be exactly dowel screw dismounting or install more firm time, screw (1) and dowel screw (3) end face tightening power do not need the very large relative motion that just can stop two-way nut (2) and dowel screw (3), this operation easily.Specifically on original dowel screw dismantling device basis, open slot (4) is driven in installation dowel screw (3) end of two-way nut (2), open slot (4) outer end is shell fragment (7), shell fragment (7) is the opening that communicates in open slot (4) three face, another side is retained in former two-way nut (2) body, namely form shell fragment relation, make shell fragment (7) that a compression stroke can be had in open slot (4) outer end to form elastic force, ensure that dowel screw (3) is firmly connected to two-way nut (2).Screw (1) and dowel screw (3) are screwed into its top of two-way nut (2) at convergence slot (6) apical grafting, reach mutual adjustment, mutually push up pressuring action.Screw (1) adopts standard component to make it to reach applied widely, the object of highly versatile.Dowel screw (3) adopts machine tooling.Key point of the present utility model is that the two-way nut (2) of the dowel screw dismantling device improved increases processing open slot, and both met production requirement, processing and fabricating also facilitates, and production cost is not high yet.Two-way nut (2) is under tensile force effect, two-way nut (2) notch aperture can be made to become large, the pitch of screw thread is changed, cause two-way nut (2) different from dowel screw (3) pitch, meet the relative motion stoping two-way nut (2) and dowel screw (3), this more convenient operation.Screw (1) for standard component and multiple screw all can use, highly versatile.
Claims (2)
1. the dowel screw dismantling device of an improvement, comprise screw, two-way nut, dowel screw, open slot, screw, convergence slot, shell fragment, it is characterized in that two-way nut (2) has open slot (4) in installation dowel screw (3) end, screw (5) extremely communicates with convergence slot (6) through open slot (4), the other end of two-way nut (2) has screw mounting screw (1), screw (1), dowel screw (3) is fit into two-way nut (2) and merges in convergence slot (6) in its top afterwards, open slot (4) is divided into shell fragment (7) and two-way nut (2) body two parts two-way nut (2), be formed on two-way nut (2) and have elastic piece structure.
2. according to the dowel screw dismantling device of improvement according to claim 1, it is characterized in that the open slot (4) of two-way nut (2) be three open-minded, one side connect at two-way nut (2) body.
