Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments.
Refering to fig. 1, it is shown that the status diagram that the position limiting structure of anti-drop bolt component of the present invention is opened.Fig. 2 is this
The status diagram that the position limiting structure of invention anti-drop bolt is packed up.In conjunction with shown in Fig. 1 and Fig. 2, anti-drop bolt packet of the present invention
It includes：Bolt body, including set threaded screw rod 10 and the screw head 20 for being fixed on 10 first end of screw rod, screw rod 10 with first
Opposite second end is held to be equipped with the storage tank along the length direction of screw rod 10 and opened up along the circumferential direction of screw rod and be communicated in appearance
Set the limiting slot of slot；And it is rotatably embedded at storage tank and the position limiting structure 30 of limiting slot junction, position limiting structure 30 can
It is placed in storage tank, can also produce and then be caught in limiting slot out of storage tank, and when position limiting structure 30 is caught in limiting slot
Position limiting structure part protrudes out screw rod 10.Position limiting structure is arranged in the present invention on bolt body, passes through rotary position limiting structure to card
Set on limiting slot and screw rod is protruded out, is limited in the second end of screw rod so that nut can not be detached from from second end, also
It is that screw rod is prevented to be detached from nut, the final safety for ensureing mechanical execution, prolonged mechanical service life, solves to a certain extent
The problem of being easy to loosen separation after the use of screw bolt and nut long-time in the prior art improves the safety of machinery and uses the longevity
Life.It is simple in structure, it is easy to operate, it is easy to accomplish.
As a better embodiment of anti-drop bolt of the present invention, refering to the enlarged diagram for the A that Fig. 3 is Fig. 1.Fig. 4
For the enlarged diagram of the B of Fig. 2.In conjunction with shown in Fig. 1 to Fig. 4, position limiting structure 30 includes：It is rotatably inserted into storage tank and limit
The sphere 31 of position slot junction；And it is fixed on the bayonet lock 32 of sphere 31, bayonet lock can be placed in the rotation of sphere 31
It sets in slot, can also be produced out of storage tank with the rotation of sphere 31 and then is caught in limiting slot, and bayonet lock is caught in limit
Bayonet lock has part to protrude out screw rod 10 when in slot.
As a better embodiment of anti-drop bolt of the present invention, the intersection of storage tank and limiting slot in screw rod is set
There is the groove for sphere is arranged.Specifically, sphere 31 is embedded in second end, so as to be freely rotated, similar to hingedly connecting
It connects.The bayonet lock 32 for being fixed on sphere 31 is just rotated with the rotation of sphere 31.The width of storage tank and limiting slot is less than sphere
31 diameter, to which sphere will not be detached from screw rod 10 from storage tank and limiting slot.Due to there is the presence of storage tank and limiting slot,
Bayonet lock 32 can only rotate in the range of storage tank and limiting slot.
When bayonet lock 32 turns in storage tank, i.e., the direction of bayonet lock 32 is consistent with the length direction of screw rod 10, then may be used

When bayonet lock 32 turns to the surface for being arranged in limiting slot and protruding out screw rod 10, to when nut 40 is from screw rod 10
Second end at when being detached from screw rod 10, bayonet lock 32 blocks nut 40, to can not take off nut 40 from the second end of screw rod 10
From screw rod 10.Bayonet lock 32 plays the role of limit.
As a better embodiment of anti-drop bolt of the present invention, when the rotation of bayonet lock 32 is placed in storage tank, bayonet lock
32 end protrudes out the second end face of screw rod 10, can be conveniently adjusted bayonet lock 32.
As a better embodiment of anti-drop bolt of the present invention, limiting slot is that part is opened in the circumferential of screw rod 10
Fan groove.The area that limiting slot opens up is small, small to the destruction of screw rod 10, ensure that whole intensity.
The present invention also provides a kind of anti-drop bolt components, including：Anti-drop bolt, including bolt body include being equipped with
The second end opposite with first end of the screw rod 10 of screw thread and the screw head 20 for being fixed on 10 first end of screw rod, screw rod 10 is equipped with edge
It the storage tank of the length direction of screw rod 10 and the limiting slot of storage tank is opened up and be communicated in along the circumferential direction of screw rod；And it can
Rotation is embedded at storage tank and the position limiting structure 30 of limiting slot junction, and position limiting structure 30 can be placed in storage tank, may be used also
It produces and then is caught in limiting slot out of storage tank, and position limiting structure part protrudes out spiral shell when position limiting structure 30 is caught in limiting slot
Bar 10；And
It is screwed together in the nut 40 of screw rod 10, by rotary position limiting structure 30 to being arranged in limiting slot and protrude out screw rod 10
Surface, to prevent nut 40 from falling off.
The present invention also provides a kind of application methods of anti-drop bolt component, include the following steps：
In rotary position limiting structure 30 to the storage tank for closing at screw rod 10；
Screw rod 10 is arranged in parts to be tightened；
Nut 40 is screwed togather from the second end of screw rod 10 and is anchored on screw rod 10；And
Rotary position limiting structure 30 is to being arranged in limiting slot and protruding out the surface of screw rod 10, to prevent nut 40 from
Two ends fall off.
Anti-drop bolt and anti-drop bolt component of the present invention and its application method have the beneficial effect that：
Position limiting structure is arranged in the present invention on bolt body, by rotary position limiting structure to being arranged in limiting slot and protrude out
Go out screw rod, limited in the second end of screw rod so that nut can not be detached from from second end, that is, prevent screw rod de- with nut
From the final safety for ensureing mechanical execution, prolonged mechanical service life, solves bolt and spiral shell in the prior art to a certain extent
The problem of being easy to loosen separation after female long-time use improves safety and the service life of machinery.It is simple in structure, operation side
Just, it is easy to accomplish.
