Abstract
The utility model relates to a kind of imperfect thread guide blot, comprise connecting thread (1) and guide thread (2), described connecting thread (1) is arranged in the cylindrical body outside of bolt, the linking of this connecting thread (1) one end is furnished with some circle guide thread (2), and the external frame of the cross section of the cusp of this guide thread (2) is circular arc line.The utility model is simple in structure, adopts the guide thread of arc surface, and guide effect is good, greatly improves the efficiency being linked and packed.
Description
Technical field
The utility model relates to hardware-joint field, particularly relates to a kind of imperfect thread guide blot.
Background technique
Bolt is a kind of conventional link, be widely used in the field such as automobile assembling, machining equipment, China Patent No. is 2013202985009 utility model patent, in the document that patent name is " a kind of bolt that is provided with guide structure ", a kind of bolt is disclosed, one end of this bolt is furnished with the screw thread being positioned on the conical surface, but the shape of these screw threads and regular screw threads are similar, it not round and smooth shape, in use the threaded engagement easily and in tapped hole is blocked, and guide effect is not fully up to expectations.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of imperfect thread guide blot, simple in structure, adopts the guide thread of arc surface, and guide effect is good, greatly improves the efficiency being linked and packed.
The utility model solves the technological scheme that its technical problem adopts: the bolt providing, comprise connecting thread and guide thread, and described connecting thread is arranged in the cylindrical body outside of bolt;
In order to realize connecting thread and tapped hole rapid abutting joint; be connected and be furnished with some circle guide thread in connecting thread one end; the external frame of the cross section of the cusp of this guide thread is circular arc line; round and smooth guide thread can cause the guiding of bolt center line and overlap with the center line of tapped hole in bolt quick rotation; and by the internal thread that is beneficial to protection opponent part, avoid damaged in assembly process.
One as bolt described in the utility model is preferred, and the number of turns of described guide thread is 2～5, and the number of turns can not be less than 2 circles, because a circle guide thread does not have leading role, selects to arrange 2～5 circle guide thread the most reasonable according to the length diameter of bolt.
Another kind as bolt described in the utility model is preferred, and the radial outer end of guide thread is arranged on the conical surface, and this is the guide effect in order further to improve guide thread.
One as bolt described in the utility model is supplemented, and is furnished with one section of smooth cylndrical surface between described guide thread and the end face of bolt, and smooth cylndrical surface makes one end energy quick insertion of bolt in tapped hole, makes guide thread can play fast leading role.
Another kind as bolt described in the utility model supplements, and between described smooth cylndrical surface and the end face of bolt, by round-corner transition, is also the effect in order further to improve leading role.
Beneficial effect
The utility model relates to a kind of imperfect thread guide blot, simple in structure, adopts the guide thread of arc surface, and guide effect is good, greatly improves the efficiency being linked and packed.
Brief description of the drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, mode of execution of the present utility model relates to a kind of imperfect thread guide blot, comprise connecting thread 1 and guide thread 2, described connecting thread 1 is arranged in the cylindrical body outside of bolt, it is characterized in that, this connecting thread 1 one end linking is furnished with some circle guide thread 2, and the external frame of the cross section of the cusp of this guide thread 2 is circular arc line.
Between described guide thread 2 and the end face of bolt, be furnished with one section of smooth cylndrical surface 3.
Between described smooth cylndrical surface 3 and the end face of bolt, pass through fillet 4 transition.
Embodiment 1
The long 60mm of guide blot, its upper end is furnished with 2 circle guide thread 2, the radial outer end of this guide thread 2 is arranged on cylndrical surface, tapped hole is aimed in one end of guide blot, the smooth cylndrical surface 3 of its one end extend in tapped hole, then make guide blot quick rotation with normal screws cutter or electric tool rifle, guide thread 2 contacts with the inwall of tapped hole and the centreline correction of guide blot is arrived and overlapped with the center line of tapped hole, finally, the supporting interlock of screw thread in connecting thread 1 and tapped hole, whole process just can complete within the time less than 1 second, quick and precisely, avoid occurring the situation of sliding tooth.
Embodiment 2
The long 120mm of guide blot, its upper end is furnished with 5 circle guide thread 2, the radial outer end of this guide thread 2 is arranged on conical surface, tapped hole is aimed in one end of guide blot, the smooth cylndrical surface 3 of its one end extend in tapped hole, then make guide blot quick rotation with normal screws cutter or electric tool rifle, guide thread 2 contacts with the inwall of tapped hole and the centreline correction of guide blot is arrived and overlapped with the center line of tapped hole, finally, the supporting interlock of screw thread in connecting thread 1 and tapped hole, whole process just can complete within the time less than 1 second, quick and precisely, avoid occurring the situation of sliding tooth.
