Abstract
The utility model provides a kind of anti-slip thread set screws component, comprise male screw thread and inner bolt, described male screw thread comprises the first screw rod and the first nut, described male screw thread offers tapped through hole along axis, described inner bolt comprises the second screw rod and the second nut, and described second screw rod is arranged in tapped through hole; The anti-slip thread set screws component that the utility model provides, first male screw thread is screwed in workpiece, again inner bolt is installed in workpiece by the tapped through hole of male screw thread, because the intensity of inside and outside two screws is higher, while inner bolt precession is fastening, even if apply excessive power, also the thread of double thread through hole can not cause damage, avoid skidding; Meanwhile, because male screw thread plays leading role, occur when avoiding fastening inner bolt because exerting oneself off-axis thus cause stripped thread phenomenon.
Description
Technical field
The utility model relates to fastener areas, especially a kind of anti-slip thread set screws component.
Background technique
In daily productive life; often can run into the phenomenon of screw stripped thread, this is due in threaded connector, and thread joint is because the power that is subject to is excessive or firmly off-axis and cause thread impaired; thus thread cannot be engaged, the consequence finally caused is threaded exactly and cannot tightens.There is stripped thread phenomenon, general solution is exactly at the larger tapped hole of the tapped hole place tapping one of institute's stripped thread, although this method effectively but have narrow limitation, such as when some install occasions less then inapplicable the method, in addition, tapping process also can the manpower and materials of at substantial, and installation efficiency is not high yet.Therefore, how set about pre-anti-slip thread from improvement screw itself, become an important problem.
Model utility content
Technical problem to be solved in the utility model is: in order to solve in tightening screw process due to firmly excessive or firmly off-axis and cause the problem of stripped thread, provide a kind of anti-slip thread set screws component.
The utility model solves the technological scheme that its technical problem will adopt: a kind of anti-slip thread set screws component, comprise male screw thread and inner bolt, described male screw thread comprises the first screw rod and the first nut, described male screw thread offers tapped through hole along axis, described inner bolt comprises the second screw rod and the second nut, and described second screw rod is arranged in tapped through hole.
Further, the length of described male screw thread is less than the length of inner bolt.
For the ease of installing male screw thread and inner bolt, described first nut is hexagonal prism structure, and described second nut is cylindric and end face offers inner hexagonal hole.
The beneficial effects of the utility model are: the anti-slip thread set screws component that the utility model provides, first male screw thread is screwed in workpiece, again inner bolt is installed in workpiece by the tapped through hole of male screw thread, because the intensity of inside and outside two screws is higher, while inner bolt precession locking, the thread of double thread through hole can not cause damage, avoid skidding; Meanwhile, because male screw thread plays leading role, avoid when screwing inner bolt and occur because of the off-axis thus cause stripped thread phenomenon of exerting oneself.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the detonation configuration schematic diagram of the utility model anti-slip thread set screws component;
Fig. 2 is assembling schematic diagram of the present utility model;
Fig. 3 is the right elevation of Fig. 2.
In figure: 1, the first screw rod, the 2, first nut, 3, tapped through hole, the 4, second screw rod, the 5, second nut, 6, inner hexagonal hole.
Embodiment
By reference to the accompanying drawings the utility model is described in detail now.This figure is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
Shown in Fig. 1 Fig. 2, the anti-slip thread set screws component that the utility model provides, comprise male screw thread and inner bolt, described male screw thread comprises the first screw rod 1 and the first nut 2, described male screw thread offers tapped through hole 3 along axis, described inner bolt comprises the second screw rod 4 and the second nut 5, and described second screw rod 4 is arranged in tapped through hole 3.
Further, the length of described male screw thread is less than the length of inner bolt.
With reference to shown in Fig. 3, in order to install male screw thread and inner bolt, described first nut 2 is hexagonal prism structure, and described second nut 5 is cylindric and end face offers inner hexagonal hole 6.
The anti-slip thread set screws component that the utility model that the utility model provides provides, first male screw thread is screwed in workpiece, again inner bolt is installed in workpiece by the tapped through hole 3 of male screw thread, because the intensity of inside and outside two screws is higher, while inner bolt precession is fastening, even if apply excessive power, also the thread of double thread through hole 3 can not cause damage, avoid skidding; Meanwhile, because male screw thread plays leading role, occur when avoiding fastening inner bolt because exerting oneself off-axis thus cause stripped thread phenomenon.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff not departing from scope of the present utility model, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
