Description
Technical field
The utility model relates to rail truck mounting technology fields, especially provide a kind of elastic cylindrical pin disassembly dress
It sets.
Background technique
Elastic cylindrical pin is also known as spring catch, is a kind of hollow cylindrical body without a head, and axially grooved, two cephalic pars have chamfering,
For positioning, connection, the fixation etc. between part.The outer diameter of elastic cylindrical pin is more slightly bigger than assembly aperture under normal conditions.
The be squeezed deformation power of generation to be restored to the original state of elastic cylindrical pin ensure that the snap action of elastic cylindrical pin.But just because of it
Snap action can play very big inhibition for the disassembly of elastic cylindrical pin.In use, its open end is stretched out on pin shaft
Through-hole, and being flared to the open end separately prevents elastic cylindrical pin from slipping away pin shaft to realize stopping function.Currently, to bullet
Property straight pin method for dismounting, straight pin is dismantled usually using punch, is easy to destroy what straight pin was installed in this way
Equipment, and the elastic cylindrical pin after disassembly can not be reused due to being destroyed.Second method is matched using plug gap
Insertion mounting pin is closed, then plug back punching bolt extracts straight pin, be only used for bullet in this way for blocking straight pin bottom
Property mounting pin when being mounted on through-hole, and because being to need to exert a force to plug, increase the difficulty of disassembly, increase installation personnel
Working strength.The third method is to be completed by installation personnel using two nipper pliers.Specifically, being first with nipper plier point
Do not clamp the end on the both sides of elastic cylindrical pin, then inward force applied to nipper plier, thus make the both sides of elastic cylindrical pin to
Same direction rotation, until opening becomes smaller, then is pulled outwardly, that is, dismantles successfully.The defect of these existing methods is it will be evident that disassembly
The deformation disunity of straight pin has seriously affected elastic cylinder after complete elastic cylindrical pin shape is not available or dismantles
The performance of pin causes waste and increased costs；In addition this method for dismounting is pure manual work, and needing to be repeated several times sometimes could incite somebody to action
Elastic cylindrical pin takes out, and due to the difference of elastic cylindrical pin installation site, increases disassembly difficulty sometimes, nipper plier is difficult effectively
It takes out, it is very big with nipper plier difficulty of construction if installation dimension is deeper, and it is easily damaged elastic cylindrical pin.If torn open
The elastic cylindrical pin unloaded is excessive, these existing methods are often difficult to meet needs, not only consume the useless installation personnel plenty of time and
Physical strength, and it is difficult to ensure quality.
Utility model content
It is easy to use the purpose of this utility model is to provide a kind of elastic cylindrical pin provision for disengagement, the elasticity after disassembly
Straight pin is regular, neat, can utilize again, can the effective solution above problem.
The technical solution of the utility model is: a kind of elastic cylindrical pin provision for disengagement, for tearing open to elastic cylindrical pin 5
It unloads, comprising: support sleeve 1, intermediate draw bar 2, expansion pin 3, nut 4；The support sleeve 1 is tube-in-tube structure, the cylinder of the support sleeve 1
Wall is equipped with window 1a；The intermediate draw bar 2 includes the locating piece 2a and screw rod 2b set on the both ends locating piece 2a；The expansion
Pin 3 includes mounting head 3a and shank 3b, and the shank 3b is equipped with expansion slot 3c and end chuck 3d, in the mounting head 3a
Equipped with screw hole；The intermediate draw bar 2 and expansion pin 3 are set to inside support sleeve 1, and 2 one end screw rod 2b of intermediate draw bar stretches out branch
1 top of support set is connect by nut 4 with support sleeve 1, and other end screw rod 2b is threadedly coupled with the mounting head 3a of expansion pin 3；It is described
The shank 3b of expansion pin 3 penetrates elastic cylindrical pin 5 and is fixed by end chuck 3d and elastic cylindrical pin 5.
The utility model has following beneficial effect:
The utility model can be with effectively save manpower and material resources, especially largely to need the place dismantled to accomplish simple and quick
Disassembly, the place unusable for position special envoy's existing method are also effective.Reach and lowers personnel labor intensity, improves production
Efficiency, the effect for improving operating condition.It is extensive with applicability, it is practical, and the elastic cylindrical pin disassembled can be again
Secondary use.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figures 1-8, a kind of elastic cylindrical pin provision for disengagement, for being dismantled to elastic cylindrical pin 5, comprising: branch
Support set 1, intermediate draw bar 2, expansion pin 3, nut 4；Support sleeve 1 is tube-in-tube structure, and the barrel of support sleeve 1 is equipped with window 1a, uses
In visual and by pliers vise intermediate draw bar；Intermediate draw bar 2 includes the locating piece 2a and screw rod 2b set on the both ends locating piece 2a；
Expansion pin 3 includes mounting head 3a and shank 3b, and shank 3b is equipped in expansion slot 3c and end chuck 3d, mounting head 3a and is equipped with
Screw hole；Intermediate draw bar 2 and expansion pin 3 are set to inside support sleeve 1, and 2 one end screw rod 2b of intermediate draw bar stretches out 1 top of support sleeve and passes through
