Model utility content
The deficiency existing for prior art, the utility model provides a kind of dual bolt, and this dual bolt comprises that one can be arranged in the auxiliary bolt of kingbolt, and 26S Proteasome Structure and Function is more perfect, can meet the usage requirement of some special occasions.
For achieving the above object, the utility model provides following technological scheme: a kind of dual bolt, comprise kingbolt and auxiliary bolt, kingbolt comprises kingbolt head and with externally threaded kingbolt bar, auxiliary bolt comprises auxiliary bolt head and with externally threaded auxiliary bolt shank, kingbolt is provided with the tapped hole wearing for auxiliary bolt in the axial direction, tapped hole runs through kingbolt head and kingbolt bar, in tapped hole, be provided with the internal thread suitable with auxiliary bolt shank outside thread, kingbolt and the movable connection of auxiliary bolt.
By adopting technique scheme, this dual bolt comprises that one can be arranged in the auxiliary bolt of kingbolt, kingbolt is provided with the tapped hole wearing for auxiliary bolt in the axial direction, tapped hole runs through kingbolt head and kingbolt bar, in tapped hole, be provided with the internal thread suitable with auxiliary bolt shank outside thread, kingbolt and the movable connection of auxiliary bolt, be that auxiliary bolt shank can be threaded with tapped hole by outside thread, in the time using this dual bolt, kingbolt mainly plays fixing effect, auxiliary bolt can play the effect of adjusting, can or not use auxiliary bolt according to actual conditions choice for use, 26S Proteasome Structure and Function is more perfect, can meet the usage requirement of some special occasions.
The utility model is further set to, and the outside thread of described kingbolt bar is right-handed thread, and the outside thread of auxiliary bolt shank is right-handed thread.
By adopting technique scheme, the outside thread of kingbolt bar and auxiliary bolt shank is right-handed thread, kingbolt mainly plays fixation, when auxiliary bolt is arranged in kingbolt, auxiliary bolt can play the effect of adjusting, because kingbolt bar and auxiliary bolt shank are right-handed thread, so in the time that auxiliary bolt shank plays regulatory role, can not drive kingbolt to rotate, guarantee that kingbolt is fixing reliable and stable.
The utility model is further set to, and the outside thread of described kingbolt bar is right-handed thread, and the outside thread of auxiliary bolt shank is left-handed thread.
By adopting technique scheme, the outside thread of kingbolt bar is right-handed thread, the outside thread of auxiliary bolt shank is left-handed thread, kingbolt mainly plays fixing effect, in the time that kingbolt is threaded too tightly, particularly after kingbolt head surprisingly breaks, kingbolt is difficult to back-out, now can be by auxiliary bolt is screwed in the tapped hole on kingbolt, by tightening auxiliary bolt when, auxiliary bolt drives kingbolt to back-out.
The utility model is further set to, and on described kingbolt head and auxiliary bolt head, is equipped with friction part.
By adopting technique scheme, on kingbolt head and auxiliary bolt head, be equipped with friction part, increase the friction factor on kingbolt head and auxiliary bolt head, be conveniently affectedly bashful stressedly, make kingbolt and auxiliary bolt more easily tighten or unscrew.
Brief description of the drawings
Fig. 1 is the structural representation of the dual bolt of the utility model;
Fig. 2 is the structural representation of the utility model kingbolt.
Reference character: 1, kingbolt; 11, kingbolt bar; 12, kingbolt head; 2, auxiliary bolt; 21, auxiliary bolt shank; 22, auxiliary bolt head; 3, tapped hole.
Embodiment
Referring to figs. 1 through Fig. 2, the dual bolt embodiment of the utility model is described further.
A kind of dual bolt, comprise kingbolt 1 and auxiliary bolt 2, kingbolt 1 comprises kingbolt head 12 and with externally threaded kingbolt bar 11, auxiliary bolt 2 comprises auxiliary bolt head 22 and with externally threaded auxiliary bolt shank 21, kingbolt 1 is provided with the tapped hole 3 wearing for auxiliary bolt 2 in the axial direction, tapped hole 3 runs through kingbolt head 12 and kingbolt bar 11, is provided with the internal thread suitable with auxiliary bolt shank 21 outside threads in tapped hole 3, kingbolt 1 and the movable connection of auxiliary bolt 2.
By adopting technique scheme, this dual bolt comprises that one can be arranged in the auxiliary bolt 2 of kingbolt 1, kingbolt 1 is provided with the tapped hole 3 wearing for auxiliary bolt 2 in the axial direction, tapped hole 3 runs through kingbolt head 12 and kingbolt bar 11, in tapped hole 3, be provided with the internal thread suitable with auxiliary bolt shank 21 outside threads, kingbolt 1 and the movable connection of auxiliary bolt 2, be that auxiliary bolt shank 21 can be threaded with tapped hole 3 by outside thread, in the time using this dual bolt, kingbolt 1 mainly plays fixing effect, auxiliary bolt 2 can play the effect of adjusting, can or not use auxiliary bolt 2 according to actual conditions choice for use, 26S Proteasome Structure and Function is more perfect, can meet the usage requirement of some special occasions.
