Description
Technical field
The utility model is related to the fixed connection structure part field of furniture making, is specifically related to a kind of combined type bias modeling
Expect expansion 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 inclined with this there is provided one kind in the case of being trimmed to eccentric orfice
The eccentric plastic expansive nut of combined type that heart 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 eccentric orfice phase there is provided one kind in the case of being trimmed to eccentric orfice
The eccentric plastic expansive nut of the combined type of matching, to overcome the deficiencies in the prior art.
In order to solve the above technical problems, the technical solution of the utility model is：Combined type bias plastic expansive nut, its is pre-
Being embedded in furniture mounting hole is used to lock threaded fastener, including has in cylinder and center the expanding screw of tapped through hole
Maternal body, the expansion nut body is main by locking section and at least two valves expansion pawl is constituted, on the inside of the expansion pawl of its leading section
The spacing being fixedly connected with wall between the projection that locking is threaded into, and adjacent expansion pawl is equal, external in expansion nut sheet
It is provided with the wall of side on the crescent moon type semicolumn of cladding expansion nut body, the concave surface of the crescent moon type semicolumn with interior
The projection in gap between embedded expansion pawl, provided with the groove matched with its projection on the convex surface of crescent moon type semicolumn.
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 and expansion nut body are contour.
Compared with the prior art, the beneficial effects of the utility model are：
The utility model sets the crescent moon type semicolumn of cladding expansion nut body on expansion nut outer body wall,
Cylindrical expansion nut is arranged to combined type eccentric expansion nut；Error is punched in Furniture manufacturing causes furniture mounting hole to offset
When, the cylindrical mounting hole on furniture part and assembly is widened in the case of being trimmed to eccentric orfice, be embedded into and the furniture mounting hole
The eccentric plastic expansive nut of combined type being engaged.It so can both be assembled according to former furniture design scheme, carry out lean and correct assembly and determine
Position, can make furnature construction solid and reliable again, strengthen stability, and have good appearance concurrently；The utility model also has simultaneously
It can repeatedly dismantle and use, be convenient to mount and dismount, reduce the advantage that waste material is produced in assembling.
Brief description of the drawings
Fig. 1 is the structural representation of the eccentric plastic expansive nut of the utility model combined type.
Fig. 2 is expansion nut body stereogram of the present utility model.
Fig. 3 is crescent moon type semicolumn stereogram of the present utility model.
Embodiment
As shown in figure 1, the eccentric plastic expansive nut of a kind of combined type that the utility model is related to, it is embedded in furniture installation
It is used to lock threaded fastener in hole, including there is the expansion nut body 1 of tapped through hole in cylinder and center, it is described
Expansion nut body 1 is main to be made up of locking section 1-1 and at least two valves expansion pawl 1-2, the expansion pawl 1-2 madial walls of its leading section
On be fixedly connected with the projection that locking is threaded into, and the spacing between adjacent expansion pawl 1-2 is equal, in expansion nut body 1
It is provided with lateral wall on the crescent moon type semicolumn 2 of cladding expansion nut body 1, the concave surface of the crescent moon type semicolumn 2
With the projection 2-1 for being embedded in gap between expansion pawl 1-2, it is provided with and its projection 2-1 on the convex surface of crescent moon type semicolumn 2
The groove 2-2 of matching；It is provided with the lateral wall of the expansion nut body 1 and the convex surface of crescent moon type semicolumn 2 in rank
Some overhead kicks of scalariform；The crescent moon type semicolumn 2 is contour with expansion nut body 1.The utility model is maternal in expanding screw
The crescent moon type semicolumn 2 of cladding expansion nut body 1 is set on the lateral wall of body 1, cylindrical expansion nut is arranged to combination
Formula eccentric expansion nut；When punching error causes the skew of furniture mounting hole in Furniture manufacturing, by the cylinder on furniture part and assembly
Mounting hole is widened be trimmed to eccentric orfice in the case of, be embedded into the eccentric plastic expansion of the combined type that is engaged with the furniture mounting hole
Nut；If being punched in Furniture manufacturing, error is larger to cause furniture mounting hole offset excessive, by the cylinder on furniture part and assembly
Shape mounting hole is widened be trimmed to big offset eccentric orfice in the case of, can the eccentric plastic expansive nut of combined type crescent moon type
The convex side of semicolumn 2 is superimposed crescent moon type semicolumn, until the eccentric plastic expansive nut of combined type is installed with big offset furniture
Untill hole is matched.
