Abstract
The utility model discloses a kind of positioning screw cap assembly, the cap colalr gasket comprising nut body and coordinate with nut body, all be provided with tapped hole in the middle of nut body and cap colalr gasket, it is characterized in that: described nut body outer side wall arranges boss, nut body is divided into upper cap nut body and lower nut body by boss; The first projection is provided with at the outer side wall of lower nut body, the madial wall of described cap colalr gasket is provided with the second projection with the first protrusions match, when cap colalr gasket coordinates with lower nut body time, second projection of cap colalr gasket and the first projection of nut body are connected together, and the end face of cap colalr gasket is then connected with boss; The utility model passes through the clamping of cap colalr gasket second projection and nut body first projection, and the inclined-plane of tapped hole opening of cap colalr gasket coordinates with the trapezoidal faces of boss, adds lifting surface area, location is snapped onto in steel ring firmly indeformable.
Description
Technical field
The utility model relates to mechanical fitting, particularly a kind of positioning screw cap assembly.
Background technique
The nut installing fixed tire is in the market a lot, when cap rotation on existing market enters tyre rim, owing to having certain wearing and tearing in car traveling itself, time of adding is used too of a specified duration, after taking out after a while, screw in power when its cap colalr gasket gives prominence to position owing to installing excessive, position given prominence to by cap colalr gasket can snap in steel ring; Again because nut body and cap colalr gasket are just by the riveted of small size, easily cause being separated of nut body and cap colalr gasket during back-out, so just make nut body scrap, the cap colalr gasket snapping in steel ring also can make steel ring damage.
Model utility content
Snap in insecure for overcoming nut body in above-mentioned technology, cap colalr gasket holds flimsy problem, and the utility model provides a kind of nut body and cap colalr gasket of can making and obtains good cooperation, makes it be connected firmly, not the positioning screw cap assembly of rapid wear ring.
For realizing above-mentioned technology, the utility model adopts following technological scheme:
A kind of positioning screw cap assembly, the cap colalr gasket comprising nut body and coordinate with nut body, all be provided with tapped hole in the middle of nut body and cap colalr gasket, it is characterized in that: described nut body outer side wall arranges boss, nut body is divided into upper cap nut body and lower nut body by boss; The first projection is provided with at the outer side wall of lower nut body, the madial wall of described cap colalr gasket is provided with the second projection with the first protrusions match, when cap colalr gasket coordinates with lower nut body time, second projection of cap colalr gasket and the first projection of nut body are connected together, and the end face of cap colalr gasket is then connected with boss.
Described boss is trapezium structure, and described cap colalr gasket end face tapped hole opening is provided with the inclined-plane coordinated with boss trapezoidal faces.
Described nut body tapped hole is divided into upper screwed hole and lower tapped hole, arranges chamfered transition between upper screwed hole and lower tapped hole.
The first described projection and the second projection are all made up of with facing directly inclined-plane.
The utility model passes through the clamping of cap colalr gasket second projection and nut body first projection, and the inclined-plane of tapped hole opening of cap colalr gasket coordinates with the trapezoidal faces of boss, adds lifting surface area, location is snapped onto in steel ring firmly indeformable.

Embodiment
As Figure 1-5, the utility model discloses a kind of positioning screw cap assembly, the cap colalr gasket 2 comprising nut body 1 and coordinate with nut body, the centre of nut body and cap colalr gasket is all provided with tapped hole, described nut body 1 outer side wall arranges boss 13, and nut body is divided into upper cap nut body 11 and lower nut body 12 by boss; Be provided with the first projection 14 at the outer side wall of lower nut body 12, the madial wall of described cap colalr gasket 2 is provided with the second projection 21 coordinated with the first projection 14, and the first described projection and the second projection are all by inclined-plane 3 with face 4 directly and form.When cap colalr gasket 2 coordinates with lower nut body 12 time, the second projection of cap colalr gasket and the first projection of nut body are connected together, and the end face of cap colalr gasket is then connected with boss 13; Described boss 13 is trapezium structure, and described cap colalr gasket end face tapped hole opening is provided with the inclined-plane 22 coordinated with boss trapezoidal faces.
The utility model passes through the clamping of cap colalr gasket second projection and nut body first projection, and the inclined-plane of tapped hole opening of cap colalr gasket coordinates with the trapezoidal faces of boss, add lifting surface area, location is snapped onto in steel ring firmly indeformable, during back-out, nut body and cap colalr gasket are not easily separated, improve the working life of nut body.
Nut body tapped hole is divided into upper screwed hole 15 and lower tapped hole 16 by the utility model, arranges inclined-plane 17 transition, arrange like this between upper screwed hole and lower tapped hole, is convenient to bolt 5 and inserts, and fixing is more firm.
As shown in Figure 6, in mating process, cap colalr gasket 2 is connected by nut body boss, cap colalr gasket 2 is made to be stuck on the boss of nut body 1, second projection of cap colalr gasket 2 inside and outside first projection of nut body 1 matched, make to connect more firm, then screw in bolt 5 and be fixed, connect firm and very convenient.
A kind of positioning screw cap assembly of the present utility model, by connecting of the boss of nut body and projection and cap colalr gasket, location to be snapped onto in steel ring firmly and not yielding, the integrative-structure of nut body makes it possible to the screw thread protecting tapped hole well, not easily rupture at screw thread place, and the screw thread of the nut body lengthened, improve access times; The inclined-plane of nut body and cap colalr gasket connects, and adds lifting surface area.It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
