Abstract
The invention discloses a structure capable of effectively preventing a bolt from falling. The structure comprises a screw rod with one end fixedly connected with a screw cap, the other end of the screw rod is provided with threads, the structure also comprises a nut matched with the threads, the screw rod is provided with a plurality of uniformly distributed through holes, and the nut is provided with a limiting hole coaxial with the through holes. The screw rod is provided with a plurality of through holes, and a limiting hole is formed in the nut matched with the screw rod, after the nut is rotatably connected onto the screw rod, the screw rod and nut can be fixed by a pin, rotation or axial movement of the nut are avoided, the nut is prevented from loosening or falling, connection stability is effectively improved, falling of parts which require connection is avoided and safety performance is higher.
Description
Technical field
The present invention relates to a kind of structure that effectively can prevent bolt falling.
Background technique
When the easy vibrative device such as motor or parts need to be pacified fixing, the normal mounting mechanism adopted is exactly bolt, when especially this kind of device or parts being connected with sheet material, often needs on bolt, to spin one again for fixing nut.But because motor can make nut also in company with vibration at the dither that operation process produces, in the course of time nut loosening can be caused to come off, cause and be connected and fixed inefficacy, easily cause the danger of dropping of device or assembly, obviously traditional bolts and nuts can not complete the installation or fixing of such shake unit well.
Summary of the invention
The object of the invention is to: a kind of structure that effectively can prevent bolt falling is provided, to solve conventional bolt and nut cannot effectively fix the problem vibrating class device or assembly.
The present invention is achieved by the following technical solution:
A kind of structure that effectively can prevent bolt falling, comprise the screw rod that one end is connected with nut, the screw rod the other end is provided with screw thread, also comprises the nut matched with this screw thread, described screw rod has some through holes be evenly arranged, described nut has the spacing hole coaxial with through hole.
Described through hole is opened in the threaded segments on screw rod.
Described through hole axis and screw rod axis perpendicular.
Described spacing hole internal diameter is greater than through hole internal diameter.
The invention has the beneficial effects as follows:
Compared with prior art, the structure that effectively can prevent bolt falling provided by the invention, screw rod is offered some through holes, and have spacing hole on the nut matched with screw rod, nut is screwed in after on screw rod, the fixing of screw rod and nut can be completed by pin, avoid nut to rotate or move axially, prevent nut loosening or come off, effectively improve the stability of connection, avoid needing dropping of link, Safety performance is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-nut, 2-screw rod, 3-nut, 4-through hole, 5-spacing hole.
Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is described further, but described in required protection domain is not limited to;
As shown in Figure 1, the structure that effectively can prevent bolt falling provided by the invention, comprise the screw rod 2 that one end is connected with nut 1, screw rod 2 the other end is provided with screw thread, also comprise the nut 3 matched with this screw thread, described screw rod 2 has some through holes 4 be evenly arranged, described nut 3 has the spacing hole 5 coaxial with through hole 4.
In order to avoid offering useless through hole in the polished rod portion of screw rod 2 and improving intensity and the bend resistance performance of screw rod 2, 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 and screw rod 2 axis perpendicular.
Described spacing hole 5 internal diameter is greater than through hole 4 internal diameter, and it can allow to occur error and pin can not be caused cannot to insert spacing hole 5 with in through hole 4.
During use, first being inserted by screw rod 2 needs in the mounting hole of connection set or assembly, then screw rod 2 is connected with sheet material mounting point with device or assembly, screw rod 2 is passed sheet material and ensures that nut 1 is fitted with device or assembly surface, then nut 3 is socketed in the threaded segments on screw rod 2, tightening nut completes to be installed and ensures that through hole 4 is coaxial with spacing hole 5, and then adopts the pin such as straight pin or cotter pin to insert and penetrate spacing hole 5 and through hole 4, namely completes fixing.Installing additional of pin can effectively avoid nut 3 rotate or move axially, and stable connection is improved.
