A kind of riveted structure of rotating connector
Technical field
The present invention relates to a kind of riveted structure, particularly a kind of riveted structure for rotating connector.
Background technique
Riveted joint is to use rivet to connect two or two above workpiece, utilizes axial force, will in part rivet hole, follow closely bar pier slightly and form ailhead, the method that multiple workpiece are connected.Specifically can be divided into movable riveted joint, fixing riveted joint, sealing riveting.For activity riveted joint, require workpiece after riveted joint, between the conjunction of formation, can mutually rotate.
In the products such as refrigerator MOD, timer, need the component of riveted joint a lot, its activity riveted structure is as shown in accompanying drawing 1,2, on component 1, be connected with nail bar 2, on another component 3, offer rivet hole 4, nail bar 2 is cylinder, through rivet hole 4, the one section of pier that stretches out rivet hole 4 is slightly formed to ailhead 5.In riveting operation, if machine tool travel is dark, or while there is difference in nail bar temperature, lathe air pressure, riveted joint effect easily changes, and tightness is inconsistent, and riveted joint tension even rivets, cause between component 1 and component 3 and cannot relatively rotate, thereby affect quality of product.And these products scripts are little with regard to volume, size is little, component are less, meet product performance, require just high for riveting operation.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of activity riveted structure, can effectively control riveted joint effect for undersized rotating connector.
Technological scheme: a kind of riveted structure of rotating connector, comprise the first component, the second component, on described the first component, be connected with nail bar, on described the second component, offer rivet hole, described nail bar upper end is set to step-like, and described nail bar is separated into bottom and top, is also provided with pad on the step surface on described bottom and described top, described nail bar is through after described rivet hole, and described pad drops on the end face top of described rivet hole.
The height of described bottom is not less than the degree of depth of described rivet hole, two connection functions between component are only played in bottom, in the time riveting, form ailhead with the top that ensures nail bar, and ailhead can not be pressed on the surface of component, can not cause riveting tension and even rivet.
The cross-sectional dimension on described top is less than the aperture of described rivet hole, and the top of nail bar wants to pass rivet hole, and without the shape of limiting to top.
Beneficial effect: compared with prior art, advantage of the present invention is that nail bar is carried out to architecture advances, be separated out different functional areas, the connection function between component is only played in nail bar bottom, nail bar top forms ailhead under machine tool travel, pad is further separated the upper and lower of following closely bar, and prevent that ailhead from directly acting on the surface of component, thereby obtain a kind of activity riveted structure that can effectively control rotating connector riveted joint effect, riveted joint effect directly can be controlled by nail bar, and the accurate control of dependence lathe that needn't be too much, make the tightness of riveted joint consistent, constant product quality.

Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiments is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
As shown in accompanying drawing 3,4, a kind of riveted structure of rotating connector, comprise on the first component 1, the second component 3, the first component 1 and be connected with on nail bar 2, the second component 3 and offer rivet hole 4, nail bar 2 upper ends are set to step-like, nail bar 2 is separated into bottom 5 and top 6, on the step surface 7 on bottom 5 and top 6, is also provided with pad 8, nail bar 2 is through after rivet hole 4, make pad 8 drop on the end face top of rivet hole 4, lathe acts on top 6 its pier is slightly formed to ailhead 9.
The present invention, by nail bar is carried out to architecture advances, is separated out different functional areas.
The effect of bottom 5 is to the first component and its connection function of the second component, make two component after riveting, can rotate by bottom 5, therefore the shape of bottom 5 is not limited to, but considers needs such as connecting effect and intensity, and itself and rivet hole 4 match for the best, the height of bottom 5 is not less than the degree of depth of rivet hole 4 simultaneously, form after ailhead 9 in riveted joint with the top 6 that ensures nail bar, ailhead 9 but can not be pressed on the surface of component, can not cause riveting tension and even rivet.
The shape on top 6 is not limited to, and it be as long as can pass rivet hole 4, and can form and prevent the ailhead 9 that comes off between component, and therefore the cross-sectional dimension on top 6 is less than the aperture of rivet hole 4.
Pad 8 is further separated top 6 and the bottom 5 of nail bar 2, and prevents that ailhead 9 from directly acting on the surface of component.
By above riveted structure, riveted joint effect directly can be controlled by nail bar, and the stroke accuracy of dependence control lathe that needn't be too much makes the tightness of riveted joint consistent, constant product quality.
