Abstract
Originally practical newly to disclose a kind of anti-drop screw firmware, belong to machanical fastener technical field.There is easy loose or dislocation after assembling in general screw firmware, to solve this technical problem, the utility model provides a kind of anti-drop screw firmware, including bolt head, screw rod and nut, it further include bolt, there is the screw rod through hole for allowing latch to pass through on the screw rod, the nut is equipped at least one nut through hole corresponding with screw rod through hole and that latch can be allowed to run through nut.The utility model may insure that screw never loosens under the premise of latch is not broken, save subsequent examination maintenance cost, improve the reliability of screw firmware.
Description
Technical field
Belong to machanical fastener technical field more particularly to a kind of screw bolt and nut component.
Background technique
Screw is almost applied to all fields as a kind of basic firmware.But from screw birth, screw it is locking
De- problem just annoyings always people.For this problem, many solutions are proposed both at home and abroad, including increase anti-slop serrations,
Tooth engaged perhaps increases holding shrapnel or using compound thread etc..But tooth engaged must assure that the hardness of tooth is greater than component
It can just be engaged, it is improper in many situations, and then structure is complicated for elastic slice and compound thread, it is too big that the production cost increases, or
Anti-loose effect is not prominent etc., can be only applied to these schemes under specific environment, it is difficult to fundamentally solve the anti-of screw
Loosen problem.
A kind of screw firmware that can effectively prevent and loosen how is developed, is those skilled in the art's urgent problem.
Utility model content
In order to overcome the problems, such as that screw loosens after assembling, it is solid that the utility model provides a kind of anti-drop screw
Part, including screw bolt and nut, the bolt include bolt head and screw rod, further include latch, and the screw rod is equipped at least one
Latch can be allowed to run through the screw rod through hole of screw rod, the nut is corresponding with screw rod through hole equipped at least one and can allow
Latch runs through the nut through hole of nut.
The screw rod through hole passes through the horizontal plane center of screw rod.
All nut through holes are in same level.
The nut through hole is externally provided with corresponding latch accommodating groove after latch bending.
The invention has the benefit that the utility model may insure that screw never loosens under the premise of latch is not broken,
It can repeatedly dismantle repeatedly, be not limited to material, screw binding force is constant, and size and the screw thread for not needing screw and nut are especially smart
It is close, it can also be anti-loose, it is possible to reduce the repair and maintenance cost in screw firmware later period improves the reliability of screw firmware.It can be with
It is produced with disposable cast molding, reduces production cost.
Detailed description of the invention
The structural decomposition diagram of Fig. 1 the utility model in embodiment 1.
The structural schematic diagram of Fig. 2 the utility model in embodiment 1.
Specific embodiment
A kind of anti-drop screw firmware, including screw bolt and nut 3, the bolt include bolt head 1 and screw rod 2, further include inserting
The tip 4, the screw rod 2 are equipped at least one screw rod through hole 21 that latch 4 can be allowed to run through screw rod 2, and the nut 3 is equipped with
At least one is corresponding with screw rod through hole 21 and can allow nut through hole 31 of the latch 4 through nut 3.Latch 4 is not necessarily intended to
Through entire nut 3, only run through the side of nut 3, the technical solution is also feasible.
As depicted in figs. 1 and 2, this example uses a screw rod through hole 21 and two nut through holes 31, and latch 4 is from spiral shell
One end of female through hole 31 is inserted into, and is passed through and is pierced by into screw rod through hole 21, then from the other end of nut through hole 31.
The screw rod through hole 21 passes through the horizontal plane center of screw rod 2.Make the uniform force on 4 both sides of latch.
All nut through holes 31 are in same level.Latch 4 can be made smoothly entirely to pass through nut through hole 31.
The nut through hole 31 is externally provided with corresponding latch accommodating groove 32 after latch 4 is bent.The part that latch 4 has more can
To be bent and be included in latch accommodating groove 32, latch accommodating groove 32 is capable of fixing the latch 4 interted and makes screw shape concise beauty
It sees.
As long as latch is not broken, screw never falls off, and can repeatedly dismantle repeatedly, is not limited to material, and screw combines
Power is constant, and size and the screw thread for not needing screw and nut are especially accurate, can also be anti-loose.The utility model can effectively reduce
Potential problems and danger existing for due to loosened screw, reduce subsequent inspection and maintenance cost, improve the reliability of screw, tear open
Bolt need to be only removed when unloading, and be able to achieve reuse.
