By adopting technique scheme, the locking device of lead screw joint arranges rationally, locking device structure is simple, inhale the internal face that ferromagnetic bar can be close to existing bolt connecting hole all the time under the effect of Returnning spring, and suction ferromagnetic bar can be adsorbed on the bolt hole internal face of irony parts, has good locking functions; Fixing device arranges rationally, and welding block can be fixed with existing hub welding, and then contiguous block is connected and fixed by set screw and nut upper-end surface, and anti-loosing effect is good, safe and reliable, and mounting or dismounting are convenient.
The utility model is set to further: the groove port that described suction ferromagnetic bar outer wall stretches out glove groove is arranged.By this setting, inhale ferromagnetic bar and arrange rationally, work more reliable.
The utility model is also set to further: described bolt shank is provided with annular groove near position, nut lower end surface, is socketed with shock-absorbing buffer pad in described annular groove.By this setting, shock-absorbing buffer pad is arranged rationally, makes screw retention better effects if.
The utility model is also set to further: described welding block lower end surface and nut lower end surface contour, and welding block face of weld is provided with several arc grooves.By this setting, welding block vibrational power flow is reasonable, fixing more reliable after making welding.
The utility model is also set to further: described welding block upper-end surface has been wholely set projection, described projection is equipped with bearing pin, and described contiguous block forms hinged by bearing pin and projection.By this setting, welding block and contiguous block easy to connect, reliable operation.
The utility model is also set to further: described shock-absorbing buffer pad is formed by rubber material manufacture.By this setting, shock-absorbing buffer pad arranges rationally, good damping effect.
The utility model has the advantages that: compared with prior art, the utility model vibrational power flow is reasonable, the locking device of lead screw joint arranges rationally, locking device structure is simple, inhale the internal face that ferromagnetic bar can be close to existing bolt connecting hole all the time under the effect of Returnning spring, and suction ferromagnetic bar can be adsorbed on the bolt hole internal face of irony parts, has good locking functions; Fixing device arranges rationally, and welding block can be fixed with existing hub welding, and then contiguous block is connected and fixed by set screw and nut upper-end surface, and anti-loosing effect is good, safe and reliable, and mounting or dismounting are convenient.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
