Description
Technical field
The utility model relates to a kind of automobile parts, in particular to a kind of car bayonet catch.
Background technique
Car bayonet catch is exactly to be used on door-plate (nail mouth), (spiral mouth, V-type mouth) on instrument board, outdoors chafing strip
On (interior buckle) etc. mostly with the bayonet of plastic products.Existing car bayonet catch, which not can guarantee, to be buckled on its corresponding position
Compatible degree, buckle can have slight positional shift after installing successfully, cause unbalance stress that can destroy the structure of components.
Utility model content
Aiming at the shortcomings of the prior art, the utility model provides a kind of steady shaped plastic fastener of increasing.
To achieve the goals above, technical solution adopted in the utility model is: increasing steady shaped plastic fastener, including button is originally
Body, the button ontology front end are equipped with discount, and the button ontology rear end is equipped with outer positioning disk and inner retainer disc, and described is default
Position disk is towards firm item is equipped on the end face of outer positioning disk one end, if the firm item is uniformly provided with around inner retainer disc axis
Dry, the firm item is symmetrical geometry.
The firm item is rectangle or cross or ring shape structure.
Seal disc is additionally provided on the button ontology, the inner retainer disc is set between outer positioning disk and seal disc.
The seal disc is the truncated cone-shaped structure of hollow out, and the seal disc is equipped with the fluting of reverse frustoconic, described
Discount with fluting slot bottom be connected.
The discount is bullet shaped shape, and the discount diameter gradually becomes smaller after becoming larger from top to bottom,
And the discount diameter rate that becomes larger becomes smaller rate less than diameter.
The inner retainer disc diameter is greater than outer positioning disk diameter.
The discount side is equipped with through slot, and the through slot is uniformly provided with several and mutual between through slot around discount
Connection.
The utility model has the beneficial effects that a kind of steady shaped plastic fastener of increasing provided by the utility model can not influence
Increase the stability after it is installed in corresponding position while buckling function again, perfection agrees with, and reduces buckle because tolerance range is come
Otherness, facilitate production, have practicability and economy.
Detailed description of the invention
Fig. 1 is the present invention looks up structural representation of the utility model；
Fig. 2 is the overlooking structure diagram of the utility model.
Specific embodiment
As Figure 1-Figure 2, increase steady shaped plastic fastener, including button ontology 1,1 front end of button ontology are equipped with discount 2,
1 rear end of button ontology is equipped with outer positioning disk 3 and inner retainer disc 4.Traditional car bayonet catch can be arranged three layers, be different from tradition
Structure, the design using double orientation disk be outer positioning disk 3 and inner retainer disc 4.Outer positioning disk 3 is set to button 1 end of ontology, interior
Positioning disk 4 is set to its relative inner.The inner retainer disc 4 is towards being equipped with firm item 5, institute on outer 3 one end end face of positioning disk
It is symmetrical geometry that the firm item 5 stated, which is uniformly provided with several, described firm items 5 around 4 axis of inner retainer disc,.Firm item
5 are set on inner retainer disc 4, and the damage to parts such as inner retainer disc 4 and discounts 2 on the one hand can be prevented in installation and removal
Hurt, on the other hand improve structural strength and stability, avoid the tolerance in assembly or is plastically deformed the influence to it and causes to determine
Position deviation or otherness.
The firm item 5 is rectangle or cross or ring shape structure.It is common symmetric geometry, herein
It is only to be illustrated to its shape, is not limited only to such shape.
Be additionally provided with seal disc 6 on the button ontology 1, the inner retainer disc 4 be set to outer positioning disk 3 and seal disc 6 it
Between.Seal disc 6 can be improved the sealing effect after assembly, while produce and process conveniently.
The seal disc 6 is the truncated cone-shaped structure of hollow out, and the seal disc 6 is equipped with the fluting 7 of reverse frustoconic, institute
The discount 2 stated is connected with 7 slot bottoms of fluting.For opposite plane disc structure, elastic restoring force is stronger, is conducive to utilize structure
Covering of the fan reaches good sealing effect.
The discount 2 is bullet shaped shape, and 2 diameter of discount gradually becomes after becoming larger from top to bottom
It is small, and 2 diameter of the discount rate that becomes larger becomes smaller rate less than diameter.Be conducive to quick assembling, while being clamped after facilitating discount 2 to buckle into
It is fixed.The structural thickness and elasticity are appropriate, are conducive to stable structure and easy to use, improve service life.
4 diameter of inner retainer disc be greater than outer 3 diameter of positioning disk, for outer positioning disk 3, inner retainer disc 4 by
Power face is more, and then forced area is bigger greatly for diameter, prevents breakage and further increases effect in sealing contact.
2 side of discount is equipped with through slot 8, the through slot 8 be uniformly provided with around discount 2 it is several, and between through slot 8
It is interconnected.Enhance radial elasticity capacity by through slot 8, while preventing the part of discount 2 airtight, influences disassembly or other accidents
Situation.
The utility model has the beneficial effects that a kind of steady shaped plastic fastener of increasing provided by the utility model can not influence
Increase the stability after it is installed in corresponding position while buckling function again, perfection agrees with, and reduces buckle because tolerance range is come
Otherness, facilitate production, have practicability and economy.
In the description of the present invention, it should be noted that term " center ", "upper", "lower", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown, is merely for convenience of describing the present invention and simplifying the description, rather than indication or suggestion is signified
Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical
Novel limitation, at the same have been shown and described above the utility model basic principles and main features and the utility model it is excellent
Point, it should be understood by those skilled in the art that.
