Abstract
The invention belongs to the field of fixed connection structural pieces for furniture manufacturing, and relates to a combined eccentric plastic expansion nut. The combined eccentric plastic expansion nut is embedded in a furniture installing hole and used for locking a fastener with a thread. The combined eccentric plastic expansion nut comprises an expansion nut body (1) mainly composed of a locking part (1-1) and at least two expansion claws (1-2). A waxing-moon-shaped half circular column (2) wrapping the expansion nut body (1) is arranged on the outer side wall of the expansion nut body (1), a protruding block (2-1) internally embedded in a gap between the expansion claws (1-2) is arranged on the concave face of the waxing-moon-shaped half circular column (2), and a groove (2-2) matched with the protruding block (2-1) of the waxing-moon-shaped half circular column (2) is formed in the convex face of the waxing-moon-shaped half circular column (2). According to the combined eccentric plastic expansion nut, assembling can be conducted according to the original furniture design scheme, accurate assembling and positioning are conducted, a furniture structure can be firm and reliable as well, stability is enhanced, and a good appearance effect is achieved.
Description
Technical field
The present invention relates to the fixed connection structure part field that furniture makes, is specifically related to a kind of combined type bias plastics swollen
Expansion nut.
Background technology
In Furniture manufacturing, plastic expansive nut is conventional fixed connection structure part, in being embedded into furniture installing hole
For locking threaded securing member, the assembling being easy between two components.Existing plastic expansive nut, its main body is in cylinder
Shape, during cylindrical furniture installing hole can only be embedded in.Present Furniture manufacturing pattern, it is typically good various in Furniture Factory's preprocessing
Furniture part and assembly, then transport is to user's Assembling.Inevitably result from punching in factory's preprocessing of furniture to miss
There is skew in poor problem, the position in hole, directly carrying out assembling according to the cylindrical installing hole can affect the assembling between component to determine
Position, reliability and appearance.When furniture installing hole causes skew because of error of punching, 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 eccentric orfice, there is provided one kind can be inclined with this
The combined type bias plastic expansive nut that heart hole matches seems particularly necessary.
The content of the invention
The technical problem to be solved in the present invention is, when error of punching in Furniture manufacturing causes furniture installing hole to offset, by family
Cylindrical installing hole on tool parts is widened in the case of being trimmed to eccentric orfice, there is provided one kind can match with the eccentric orfice
Combined type bias plastic expansive nut, to overcome the deficiencies in the prior art.
To solve above-mentioned technical problem, the technical scheme is that：Combined type bias plastic expansive nut, it is embedded in
It is used to lock threaded securing member in furniture installing hole, it is maternal including the expanding screw in cylindrical and center with tapped through hole
Body, the expansion nut body mainly by locking section and at least two lobes expansion pawl constitute, on the expansion pawl madial wall of its leading section
The spacing being fixedly connected between the projection that locking is threaded into, and adjacent expansion pawl is equal, in expansion nut outer body wall
On be provided with the crescent moon type semicolumn of cladding expansion nut body, with being embedded on the concave surface of the crescent moon type semicolumn
The projection in gap, is provided with the groove matched with its projection on the convex surface of crescent moon type semicolumn between expansion pawl.
Combinations of the above formula bias plastic expansive nut be, the lateral wall and crescent moon type semicircle of the expansion nut body
Stepped some overhead kicks are provided with the convex surface of post.
Combinations of the above formula bias plastic expansive nut is that the crescent moon type semicolumn is contour with expansion nut body.
Compared with the prior art, the invention has the beneficial effects as follows：
The present invention arranges the crescent moon type semicolumn of cladding expansion nut body on expansion nut outer body wall, by cylinder
Expansion nut is arranged to combined type eccentric expansion nut；When error of punching in Furniture manufacturing causes furniture installing hole to offset, by family
Cylindrical installing hole on tool parts is widened in the case of being trimmed to eccentric orfice, is embedded into what is be engaged with the furniture installing hole
Combined type bias plastic expansive nut.So both can assemble according to former furniture design scheme, carry out lean and correct assembly positioning, can make again
Furnature construction is solid and reliable, strengthens stability, and has good appearance concurrently；Simultaneously the present invention also can repeatedly be dismantled and made
With, it is convenient to mount and dismount, reduce the advantage that waste material is produced in assembling.
Description of the drawings
Fig. 1 is the structural representation of combined type bias plastic expansive nut of the present invention.
Fig. 2 is the expansion nut body stereogram of the present invention.
Fig. 3 is the crescent moon type semicolumn stereogram of the present invention.
Specific embodiment
As shown in figure 1, a kind of combined type bias plastic expansive nut according to the present invention, it is embedded in furniture installing hole
For locking threaded securing member, including the expansion nut body 1 in cylindrical and center with tapped through hole, the expansion
Nut body 1 is main to be made up of locking section 1-1 and at least two lobes expansion pawl 1-2, solid on the expansion pawl 1-2 madial walls of its leading section
Surely the spacing being connected between the projection that locking is threaded into, and adjacent expansion pawl 1-2 is equal, in the outside of expansion nut body 1
The crescent moon type semicolumn 2 of cladding expansion nut body 1 is provided with wall, is carried on the concave surface of the crescent moon type semicolumn 2
The projection 2-1 in gap between expansion pawl 1-2 is embedded in, is provided with the convex surface of crescent moon type semicolumn 2 and is matched with its projection 2-1
Groove 2-2；It is provided with the lateral wall of the expansion nut body 1 and the convex surface of crescent moon type semicolumn 2 stepped
Some overhead kicks；The crescent moon type semicolumn 2 is contour with expansion nut body 1.The present invention is in the lateral wall of expansion nut body 1
The upper crescent moon type semicolumn 2 for arranging cladding expansion nut body 1, by cylindrical expansion nut combined type eccentric expansion is arranged to
Nut；When error of punching in Furniture manufacturing causes furniture installing hole to offset, the cylindrical installing hole on furniture part and assembly is widened
In the case of being trimmed to eccentric orfice, the combined type bias plastic expansive nut being engaged with the furniture installing hole is embedded into；If family
Error of punching in tool production is larger to cause furniture installing hole side-play amount excessive, and the cylindrical installing hole on furniture part and assembly is being opened up
In the case that width is trimmed to big side-play amount eccentric orfice, can be convex in the crescent moon type semicolumn 2 of combined type bias plastic expansive nut
Surface side is superimposed crescent moon type semicolumn, is until combined type bias plastic expansive nut is matched with big side-play amount furniture installing hole
Only.
