Description
Technical field
A kind of safety pin that the utility model relates to prevent contact ring from falling off, it is specially a kind of superfluous for railway movable contact group
Remaining combination Anti-dropping safety pin.
Background technique
At present during the manufacturing, the measure for preventing small parts from falling off from cylindrical body generally use split pin or
It is baffle ring；Split pin disadvantage in use is to need to bend tail portion during the installation process, is usually all made of artificial curved by hand
Folding, after bending because lack corresponding tool be also easy to produce herein firmly it is curved, cause stress to concentrate, in the long-term use part with open
Mouth pin collides and is broken bending place because of fatigue.
Baffle ring during installing and using there is also problem of stress concentration, baffle ring since annulus and bolt are in same plane,
It causes during the installation process, the hand that needs to be misplaced up and down with tool breaks annulus and bolt, and baffle ring can just be made to be attached to the hole of workpiece in this way
It is interior, manually with dislocation moves baffle ring above and below tool when be easy to cause bolt root cracked and stress is concentrated, for a long time
Fatigue break is be easy to cause after use, for this purpose, it is proposed that a kind of be used for railway movable contact group Fault-tolerant Integrated Anti-dropping safety pin.
Utility model content
The purpose of this utility model is to provide one kind to be used for railway movable contact group Fault-tolerant Integrated Anti-dropping safety pin, with solution
The problem of certainly being proposed in background technique.
To achieve the above object, the utility model provides the following technical solutions: one kind being used for railway movable contact group redundant group
Close Anti-dropping safety pin, including connection ring, bolt, fixed ring, movable contact block, movable contact ring and mounting hole, the movable contact block
Top be provided with several movable contact rings, the top of the movable contact ring is through offering mounting hole, the side of the connection ring
It is provided with bolt, the other side of the connection ring is provided with fixed ring, and the bolt may pass through installation far from the side of connection ring
The inside in hole.
Preferably, the manufacture material of the connection ring, bolt and fixed ring is all made of 304 stainless steels, and diameter is Ф 1- Ф
2。
Preferably, the manufacture material of the connection ring is identical as bolt, and the connection ring is annulus made of bolt curling.
Compared with prior art, the utility model has the following beneficial effects: the utility model first with hand by bolt and
Fixed ring is mutually broken into two with one's hands by the both ends of connection ring, and bolt is then put into the inside of mounting hole, then pushes ahead connection ring,
So that the circular arc of fixed ring side is clamped in the surface of movable contact ring, this Anti-dropping safety latch structure is simple, it is convenient and practical,
Problem of stress concentration will not be generated during installing and dismounting, and the utility model is structurally reasonable, it is easy to use.
Detailed description of the invention
Fig. 1 is the utility model the side view figure structure schematic representation；
Fig. 2 is the utility model front view structural representation；
Fig. 3 is the utility model movable contact block the side view figure structure schematic representation；
Fig. 4 is the utility model top view mounting structure schematic diagram.
In figure: 1 connection ring, 2 bolts, 3 fixed rings, 4 movable contact blocks, 5 movable contact rings, 6 mounting holes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: one kind is anti-for railway movable contact group Fault-tolerant Integrated
Fall off safety pin, including connection ring 1, bolt 2, fixed ring 3, movable contact block 4, movable contact ring 5 and mounting hole 6, the movable contact
The top of block 4 is provided with several movable contact rings 5, and the top of the movable contact ring 5, which is run through, offers mounting hole 6, the connection ring 1
Side be provided with bolt 2, the other side of the connection ring 1 is provided with fixed ring 3, the manufacture material of the connection ring 1 and inserts
Pin 2 is identical, and the connection ring 1 is annulus made of bolt 2 crimps, and the bolt 2 may pass through installation far from the side of connection ring 1
The inside in hole 6, the manufacture material of the connection ring 1, bolt 2 and fixed ring 3 are all made of 304 stainless steels, and diameter is Ф 1- Ф 2.
In use, firstly, bolt 2 and fixed ring 3 are mutually broken into two with one's hands by the both ends of connection ring 1 with hand, then far by bolt 2
One end from connection ring 1 puts the inside of mounting hole 6 into, then pushes ahead connection ring 1, presss from both sides the circular arc of 3 side of fixed ring
It holds and installation can be completed on the surface of movable contact ring 5.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
