Description
Technical field
The utility model is related to furniture connecting component technical field, is specifically related to a kind of ellipse plastic expansive nut.
Background technology
In Furniture manufacturing, plastic expansive nut is conventional fixed connection structure part, is embedded into furniture mounting hole
For locking threaded fastener, it is easy to the assembling between two components.Existing plastic expansive nut, its main body is in cylinder
Shape, can only be embedded in cylindrical furniture mounting hole.Present Furniture manufacturing pattern, is typically good various in Furniture Factory's preprocessing
Furniture part and assembly, then transports user's Assembling.Punching is inevitably resulted from factory's preprocessing of furniture to miss
There is skew in poor the problem of, the position in hole, directly carrying out assembling according to the cylindrical mounting hole can influence the assembling between component to determine
Position, reliability and appearance.In furniture mounting hole when being offset caused by punching error, in order to according to former furniture design side
Case positioning assembling, the cylindrical mounting hole on component is widened can be ellipse with this there is provided one kind in the case of being trimmed to elliptical aperture
The ellipse plastic expansive nut that circular hole matches seems particularly necessary.
The content of the invention
The technical problems to be solved in the utility model is, when punching error causes the skew of furniture mounting hole in Furniture manufacturing,
Cylindrical mounting hole on furniture part and assembly is widened can be with the elliptical aperture phase there is provided one kind in the case of being trimmed to eccentric orfice
The ellipse plastic expansive nut of cooperation, to overcome the deficiencies in the prior art.
In order to solve the above technical problems, the technical solution of the utility model is：Ellipse plastic expansive nut, it is embedded in
It is used to lock threaded fastener, including locking section and connected bulge in oval mounting hole, bulge is included extremely
Few two valves expansion pawl, it is in integrally elliptic cylindrical shape structure that the locking section is affixed with bulge, is set on cylindroid bottom surface
Have a screwed hole of the insertion cylindroid bottom surface, the cylindroid center of center deviation of screwed hole, the screw thread of the screwed hole with it is tight
The screw thread of firmware is engaged.
Above-mentioned ellipse plastic expansive nut is, in the one side that the expansion pawl is in contact with the oval mounting hole
Some overhead kicks are provided with, are easy to that ellipse plastic expansive nut is clamped in mounting hole in assembling.
Compared with the prior art, the beneficial effects of the utility model are：
The outline of plastic expansive nut is arranged to elliptic cylindrical shape by the utility model, sets the insertion cylindroid bottom surface
Screwed hole, and screwed hole is configured with cylindroid into bias；When punching error causes the skew of furniture mounting hole in Furniture manufacturing,
Cylindrical mounting hole on furniture part and assembly is widened in the case of being trimmed to eccentric orfice, be embedded into what is be engaged with the elliptical aperture
Ellipse plastic expansive nut, can both carry out lean and correct assembly positioning, good appearance can be reached again, while dress can also be reduced
Generation with middle waste material.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model ellipse plastic expansive nut.
Embodiment
As shown in figure 1, a kind of ellipse plastic expansive nut that the utility model is related to, it is embedded in oval mounting hole
For locking threaded fastener, including locking section 1 and connected bulge 2, bulge 2 expands including at least two valves
Pawl, it is in integrally elliptic cylindrical shape structure that the locking section 1 is affixed with bulge 2, and insertion is provided with cylindroid bottom surface should
The screwed hole 3 of cylindroid bottom surface, the cylindroid center of center deviation of screwed hole 3, the screw thread of the screwed hole 3 and fastener
Screw thread is engaged；Some overhead kicks are provided with the one side that the expansion pawl is in contact with the oval mounting hole, are easy to assembling
It is middle that ellipse plastic expansive nut is clamped in mounting hole.The outline of plastic expansive nut is arranged to ellipse by the utility model
It is cylindric, the screwed hole 3 of the insertion cylindroid bottom surface is set, and screwed hole 3 is configured with cylindroid into bias；Furniture manufacturing
When middle punching error causes the skew of furniture mounting hole, the cylindrical mounting hole on furniture part and assembly is widened and is trimmed to eccentric orfice
In the case of, the ellipse plastic expansive nut being engaged with the elliptical aperture is embedded into, lean and correct assembly positioning can be both carried out, can reach again
To good appearance, while the generation of waste material in assembling can also be reduced.
