Abstract
A kind of Split plastic buckle, including plastic screw, plastic cap nut, are characterized in that：The plastic screw includes screw flange, the screw body with screw swivelling chute being arranged on screw flange；Plastic cap nut includes carrying nut flange of the inwall with nut screw thread of the buckling groove coordinated with screw flange, some nut expansion pin being arranged on nut flange.Can be back-outed as bolt using screwdriver, convenient disassembly is simple in construction, during dismounting will not failure criteria part in itself, can continuously recycle, less there are problems that due to the component surface of instrument reason damage installation.
Description
Technical field
The utility model belongs to plastic standard part field of structural design, specifically a kind of point for being easily installed and dismantling
Body formula plastic buckle.
Background technology
Generally installed, be characterized in using plastic standard part on the inside and outside decorations parts of automobile at present：It is simple in construction, peace
Dress is convenient, light weight, good economy performance.But when dismantling, because structure limits, prevent it from being used as bolt or self threading pin
Screwdriver or sleeve are directly back-outed, and generally require and extract standard component by special extracting tool, and this dismounting mode is easily
Failure criteria part in itself, makes it difficult to continuously repeat use, and in unloading process, instrument is also possible to connect with component surface
Touch, damage the component surface of its installation.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of plastic standard part of brand new.
Technical scheme is used by the utility model：The plastic buckle of the split type threaded structure includes plastic spiral
Nail, plastic cap nut, are characterized in that：The plastic screw includes screw flange, is arranged on screw flange and carries screw
The screw body of swivelling chute；Plastic cap nut includes spiral shell of the inwall with nut screw thread for carrying the buckling groove coordinated with screw flange
Cap flange, some nut expansion pin being arranged on nut flange.
The nut expansion pin is circumferentially distributed on plastic cap nut.
The beneficial effects of the utility model：It can be back-outed as bolt using screwdriver, convenient disassembly is simple in construction, tears open
When unloading will not failure criteria part in itself, can continuously recycle, less exist due to instrument reason damage installation parts table
Face problem.During installation, plastic screw is pressed into plastic cap nut, due to plastic screw diameter than nut expand bottoms in
Footpath is big, can extrude nut expansion pin, nut expansion pin is outwards expanded, mounting surface is blocked, so as to which part be fixed.During dismounting,
Because buckle has helicitic texture, plastic screw can be back-outed by the screw swivelling chute at the top of plastic screw with screwdriver, this
When, the nut expansion pin below plastic cap nut sets back again to be put, not with mounting surface clamping, you can plastic cap nut is extracted.And
And when dismantling, screwdriver need not contact piece surface, will not part of damage surface.

Pin.
Embodiment
Below in conjunction with Fig. 1 ~ 6, content of the present utility model is described in detail by specific embodiment.The Split plastic buckle
Including plastic screw 1, plastic cap nut 2.Wherein, plastic screw includes screw flange 1-2, is arranged on screw flange and carries spiral shell
Follow closely swivelling chute 1-1 screw body 1-3.Plastic cap nut includes carrying the inner wall belt with the screw flange 1-2 buckling groove 2-2 coordinated
There are nut screw thread 2-3 nut flange 2-1, some nut expansion pin 2-4 ~ 2-9 being arranged on nut flange.Nut expands pin
Circumferentially it is distributed on plastic cap nut, and the internal diameter surrounded is less than the internal diameter of nut threaded portion.
Before part is installed, plastic screw 1 is inserted into the nut screw thread 2-3 of plastic cap nut 2 by screw body 1-3,
And 1/3rd are only inserted, ensures that six nuts expansion pin 2-4~2-9 on plastic cap nut 2 is not deformed.Will during installation
After snap fit 3 and buckle shackle member alignment position, the Split plastic buckle assembled is inserted in mounting hole（Such as Fig. 1
It is shown）, the screw flange 1-2 on plastic screw 1 is then pressed with finger, until making screw flange 1-2 and nut flange 2-1,
Plastic screw 1 is pushed into plastic cap nut 2 completely（As shown in Figure 2）, now, due to nut expansion pin 2-4~2-9 surround in
Footpath is less than screw body 1-3 diameter, can extrude nut expansion pin 2-4~2-9, make its outside dilatancy, with buckle clamping
Part 4 connects and fixes.
When dismantling part, cruciate flower screwdriver is inserted into screw swivelling chute 1-1, bit rotary screwdriver can be by plastic spiral
Nail 1 is back-outed；Now, nut expansion pin 2-4~2-9 extrudes without external force, returns to original state again, directly can pull out plastic cap nut 2
Go out.
