Abstract
The invention belongs to the technical field of furniture connecting pieces and relates to an elliptic plastic expansion nut. The elliptic plastic expansion nut is embedded in an elliptic installation hole of a furniture part and is used for locking a fastener with a thread. The elliptic plastic expansion nut comprises a locking part (1) and an expansion part (2) connected with the locking part (1). The expansion part (2) comprises at least two expansion claws. The locking part (1) and the expansion part (2) are fixedly and integrally connected to be of an elliptic cylinder-shaped structure. A threaded hole (3) penetrating the bottom face of the elliptic cylinder is formed in the bottom face of the elliptic cylinder. The center of the threaded hole (3) deviates from the center of the elliptic cylinder. A thread of the threaded hole (3) is matched with the thread of the fastener. The face, making contact with the elliptic installation hole, of each expansion claw is provided with multiple barbs. When the furniture installation hole deviates due to punching errors during furniture production, under the condition that the cylindrical installation hole in the furniture part is widened to be trimmed into an eccentric hole, the elliptic plastic expansion nut matched with the elliptic hole is embedded, accordingly accurate assembling and positioning can be conducted, and a good appearance effect can be achieved as well.
Description
Technical field
The present invention relates to furniture connecting component technical field, it 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 in furniture installing hole
For locking threaded securing member, 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 installing hole.Present Furniture manufacturing pattern, typically good various in Furniture Factory's preprocessing
Furniture part and assembly, then transports user's Assembling.Inevitably result from punching by mistake in factory's preprocessing of furniture
The problem of difference, there is skew in the position in hole, directly carry out, according to this cylindrical installing hole, the assembling that assembling can affect between component fixed
Position, reliability and appearance.When furniture installing hole causes skew because of punching error, in order to according to former furniture design side
Case positioning assembling, the cylindrical installing hole on component is widened in the case of being trimmed to elliptical aperture, provides one kind ellipse with this
The ellipse plastic expansive nut that circular hole matches seems particularly necessary.
Content of the invention
The technical problem to be solved in the present invention is, when in Furniture manufacturing, punching error causes the skew of furniture installing hole, by family
Cylindrical installing hole on tool parts is widened in the case of being trimmed to eccentric orfice, provides one kind can match with this elliptical aperture
Ellipse plastic expansive nut, to overcome the deficiencies in the prior art.
For solving above-mentioned technical problem, the technical scheme is that：Ellipse plastic expansive nut, it is embedded in ellipse
It is used in installing hole locking threaded securing member, including locking section and connected bulge, bulge includes at least two
Lobe expands pawl, described locking section and bulge affixed integral in elliptic cylindrical shape structure, cylindroid bottom surface is provided with and passes through
Lead to the screwed hole of this cylindroid bottom surface, the cylindroid center of center deviation, the screw thread of described screwed hole and the securing member of screwed hole
Screw thread match.
Above-mentioned ellipse plastic expansive nut is, in the one side that described expansion pawl is contacted with described ellipse installing hole
It is provided with some overhead kicks, be easy in assembling, ellipse plastic expansive nut be clamped in installing hole.
Compared with the prior art, the invention has the beneficial effects as follows：
The outline of plastic expansive nut is arranged to elliptic cylindrical shape by the present invention, arranges the screwed hole of this cylindroid bottom surface of insertion,
And make screwed hole become eccentric configuration with cylindroid；When in Furniture manufacturing, punching error causes the skew of furniture installing hole, by furniture
Cylindrical installing hole on parts is widened in the case of being trimmed to eccentric orfice, is embedded into the ellipse matching with this elliptical aperture
Plastic expansive nut, both can carry out lean and correct assembly positioning, and can reach good appearance again, can also reduce useless in assembling simultaneously
The generation of material.
Brief description
Fig. 1 is the structural representation of ellipse plastic expansive nut of the present invention.
Specific embodiment
As shown in figure 1, a kind of ellipse plastic expansive nut according to the present invention, it is embedded in oval installing hole and is used for
Lock threaded securing member, including locking section 1 and connected bulge 2, bulge 2 includes at least two lobes and expands pawl,
Described locking section 1 affixed with bulge 2 integral in elliptic cylindrical shape structure, this ellipse of insertion is provided with cylindroid bottom surface
The screwed hole 3 of post bottom surface, the cylindroid center of center deviation of screwed hole 3, the screw thread of described screwed hole 3 and the screw thread of securing member
Match；Described expansion is provided with some overhead kicks in the one side that pawl is contacted with described ellipse installing hole, and being easy in assembling will
Ellipse plastic expansive nut is clamped in installing hole.The outline of plastic expansive nut is arranged to elliptic cylindrical shape by the present invention,
The screwed hole 3 of setting this cylindroid bottom surface of insertion, and make screwed hole 3 become eccentric configuration with cylindroid；Punch in Furniture manufacturing
When error causes the skew of furniture installing hole, the cylindrical installing hole on furniture part and assembly is widened the situation being trimmed to eccentric orfice
Under, it is embedded into the ellipse plastic expansive nut matching with this elliptical aperture, both can carry out lean and correct assembly positioning, can reach good again
Good appearance, can also reduce the generation of waste material in assembling simultaneously.
