SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the weak point in the prior art, provide a furniture embedded nut, aim at solving furniture board when twisting connecting screw, embedded nut skids and twists at least one of the hard scheduling problem when connecting screw.
In order to achieve the above purpose, the utility model adopts the following scheme:
the utility model provides a furniture embedded nut, includes the nut body that the center runs through, the nut body is provided with connecting portion and the portion of expanding, connecting portion are located the portion top of expanding, be provided with the incision that a plurality of sword were cut in the portion of expanding, be provided with the internal thread on the central wall of nut body, be provided with the external screw thread on the outer wall of nut body, through the incision that forms the sword and cut, the surface of embedded nut laminating connecting screw when making connecting screw get into embedded nut on the one hand, and embedded nut expands easily, does benefit to simultaneously and sets up full thread at nut body center for connecting screw gets into embedded nut's power change is very little or unchangeable, and embedded nut can not slide the tooth with panel in laborsaving while, the external screw thread of nut body does benefit to the nut body and is connected more and more tightly with panel when.
In one or more embodiments, an annular limiting piece extending outwards is further arranged above the connecting portion, the limiting piece, the connecting portion and the expanding portion are integrally formed, and the limiting piece prevents the embedded nut from entering the plate too deeply.
In one or more embodiments, a tapered hole is formed in the center of the nut body, and the diameter of the tapered hole increases from the bottom end of the expansion portion to the top end of the connection portion, so that the connection screw enters the nut body to expand the center hole of the nut body, and the expansion portion expands.
In one or more embodiments, the inner wall of the conical hole is provided with full teeth, so that the connecting screw rod can enter the central hole conveniently, and the labor and the time are saved.
In one or more embodiments, the outer wall of the expansion portion is provided with external threads so that the nut body can be connected with the plate more tightly after entering the plate and more rotatably, the sliding teeth are avoided, and the outer wall of the connecting portion forms a polygon so that the installation depth of the nut body can be adjusted through a wrench.
In one or more embodiments, at least two circles of threads are arranged on the central hole of the nut body corresponding to the connecting part.
In one or more embodiments, the external threads taper upwardly and outwardly from the bottom end of the expander to facilitate manual pressing of the nut body into the panel.
In one or more embodiments, a counter bore is formed at the entrance end of the connecting screw of the nut body, so that the connecting screw slightly sinks after the connecting screw is screwed on the nut body.
Has the advantages that: the utility model provides a furniture embedded nut through the incision that forms the sword and cut, the surface of embedded nut laminating connecting screw when making connecting screw get into embedded nut on the one hand, and embedded nut expands easily, does benefit to simultaneously and sets up full thread at nut body center for connecting screw gets into embedded nut's power change is very little or unchangeable, and embedded nut can not slide the tooth with panel in laborsaving while, the external screw thread of nut body does benefit to the nut body and is connected more and more tightly with panel when rotating.
