Abstract
The invention discloses an anti-falling bolt component. The anti-falling bolt component comprises a screw rod fixedly connected with a screw cap at one end; and a thread is arranged at the other end of the screw rod. The anti-falling bolt component further comprises a nut matched with the thread; multiple through holes are uniformly distributed in the screw rod; and the nut is provided with limiting holes coaxial with the through holes. The multiple through holes are formed in the screw rod; the limiting holes are formed in the nut matched with the screw rod; and after the nut is screwed on the screw rod, the fixation of the screw rod and the nut can be finished through a pin, so that the rotation or the axial movement of the nut is prevented, the looseness or the falling of the nut is prevented, the connecting stability is effectively improved, the falling of parts needing to be connected is prevented, and the safety is higher.
Description
Technical field
The present invention relates to a kind of bolt, be specifically related to a kind of anti-drop bolt assembly.
Background technology
Motors etc. easily produce the device of vibration or parts need pacify when fixing, frequently with installing mechanism
It is exactly bolt, when especially this kind of device or parts being connected with sheet material, generally requires and spin again on bolt
One for fixing nut.But owing to motor can make nut also companion at the dither that operation process produces
Vibration, can cause nut loosening to come off in the course of time, cause connection solid failure, easily cause device or group
The danger of dropping of part, it is clear that traditional bolts and nuts can not complete well such vibrating device installation or
Fixing.
Summary of the invention
It is an object of the invention to: a kind of anti-drop bolt assembly is provided, with solve conventional bolt and nut without
The effectively fixing vibration class device of method or the problem of assembly.
The present invention is achieved by the following technical solution:
A kind of anti-drop bolt assembly, is connected with the screw rod of nut including one end, and the screw rod other end is provided with screw thread,
Also include the nut matched with this screw thread, described screw rod has some through holes being evenly arranged, described spiral shell
The spacing hole coaxial with through hole is had on mother.
Described through hole is opened in the threaded segments on screw rod.
Described through hole axis is perpendicular with screw rod axis.
Described spacing hole internal diameter is more than through hole internal diameter.
The invention has the beneficial effects as follows:
Compared with prior art, the anti-drop bolt assembly that the present invention provides, screw rod is offered some leading to
Hole, and have spacing hole on the nut matched with screw rod, after nut is screwed on screw rod, Ke Yitong
Cross pin and complete the fixing of screw rod and nut, it is to avoid nut rotates or moves axially, and prevents nut loosening
Or come off, it is effectively increased the stability of connection, it is to avoid needing dropping of connector, security performance is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure: 1-nut, 2-screw rod, 3-nut, 4-through hole, 5-spacing hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described further, but required protection domain is also
It is not limited to described；
As it is shown in figure 1, the anti-drop bolt assembly that the present invention provides, it is connected with the screw rod 2 of nut 1 including one end,
Screw rod 2 other end is provided with screw thread, also includes the nut 3 matched with this screw thread, described screw rod 2 has some
The through hole 4 being evenly arranged, described nut 3 has the spacing hole 5 coaxial with through hole 4.
In order to avoid offering useless through hole the intensity improving screw rod 2 and buckle resistance in the polished rod portion of screw rod 2
Can, described through hole 4 is opened in the threaded segments on screw rod 2.
For the ease of the plug-in mounting of pin, described through hole 4 axis is perpendicular with screw rod 2 axis.
Described spacing hole 5 internal diameter is more than through hole 4 internal diameter, and it can allow error occur without causing the pin cannot
Insert in spacing hole 5 and through hole 4.
During use, first screw rod 2 is inserted in the installing hole needing attachment means or assembly, then by screw rod 2 and dress
Put or assembly is connected with sheet material installation site, screw rod 2 through sheet material and is ensured nut 1 and device or assembly table
Fitting in face, is then socketed in the threaded segments on screw rod 2 by nut 3, and tightening nut completes to install and ensure
Through hole 4 is coaxial with spacing hole 5, uses the pin such as straight pin or split pin to insert and penetrate spacing hole 5 He the most again
Through hole 4, i.e. completes fixing.The installing additional of pin can be prevented effectively from nut 3 and rotate or move axially, even
Connect steadiness to be improved.
