Description

Pre-embedded nut for wooden furniture

Technical Field

The utility model relates to a furniture accessory technical field, more specifically say, it relates to a buried nut in advance that is used for wooden furniture.

Background

When the embedded nut is installed on the wooden furniture, the plate needs to be punched, and then the nut is knocked or screwed into the hole, so that great labor is consumed when the nut is embedded and punched; in addition, in general, a nut driven into a plate material is likely to be loosened when it is engaged with a screw.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a nut squeezes into panel laborsaving and the nut is being used for the embedded nut on wooden furniture difficult not hard up with the screw cooperation.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a buried nut in advance for on wooden furniture, including connecting gradually and coaxial first connector, midbody and second connector, first connector, second connector and midbody form the annular, be equipped with a plurality of triangular pyramids on the outer wall of first connector, a plurality of triangular pyramids encircle the axis of first connector and evenly arrange, the length direction of a plurality of triangular pyramids is the same with the axial of first connector, the direction of the fixed bottom surface of apex to triangular pyramid of triangular pyramid is the same with the direction of first connector to second connector, be equipped with a plurality of triangular prisms on the second connector, the axis that a plurality of triangular prisms encircle the second connector evenly arranges, a plurality of triangular pyramids and a plurality of triangular prism one-to-one and the triangular pyramid and the triangular prism of mutual correspondence are arranged in same straight line, the bottom surface of triangular pyramid is the same with the bottom surface of triangular prism.

Further, be equipped with the rubber circle in the annular, the rubber circle is encircleed on the midbody, and it has the bag of placing to inlay on the rubber circle, places the bag and is equipped with hollow chamber that holds, holds the intracavity and is equipped with glue, is equipped with on the midbody and holds the through-hole that the chamber corresponds.

Furthermore, a plurality of rubber bulges are arranged on the outer wall of the rubber ring, and the rubber bulges extend out of the annular groove.

By adopting the technical scheme, the beneficial effects of the utility model are that: when the embedded nut is driven into a hole in a plate of wooden furniture, the triangular pyramid on the first connecting body is equivalent to a sharp cutting edge, and the inner wall of the hole is broken, so that the nut is more convenient to drive into the furniture; when the nut is squeezed into furniture, articles such as practical sharp needles and the like penetrate through the through holes to be punctured by the placing bags, so that glue flows out, the glue flows in the annular groove and connects the rubber ring, the nut and the furniture together, the nut is firmly fixed on the furniture, and the nut is not easy to loosen due to rotation of the screw due to matching of the screw and the nut.

Fig. 2 is a schematic sectional structure diagram of an embodiment of the present invention.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

The embedded nut for the wooden furniture is labor-saving in driving the nut into the board, and the nut is not easy to loosen when being matched with a screw.

The utility model provides a concrete implementation scheme: the connecting device comprises a first connecting body 1, an intermediate body 2 and a second connecting body 3 which are sequentially connected and coaxial, wherein the first connecting body 1, the second connecting body 3 and the intermediate body 2 form a ring groove 4, a plurality of triangular pyramids 5 are arranged on the outer wall of the first connecting body 1, the plurality of triangular pyramids 5 are uniformly distributed around the axis of the first connecting body 1, the length directions of the plurality of triangular pyramids 5 are the same as the axial direction of the first connecting body 1, the directions from the vertexes of the triangular pyramids 5 to the fixed bottom surfaces of the triangular pyramids 5 are the same as the directions from the first connecting body 1 to the second connecting body 3, a plurality of triangular columns 6 are arranged on the second connecting body 3, the plurality of triangular columns 6 are uniformly distributed around the axis of the second connecting body 3, the triangular pyramids 5 and the triangular columns 6 which correspond one to one another and are arranged on the same straight line, the bottom surfaces of the triangular pyramids 5 and the bottom surfaces of the, The areas are the same.

When the embedded nut is driven into a hole in a plate of wooden furniture, the triangular pyramid 5 on the first connecting body 1 is equivalent to a sharp cutting edge, and the inner wall of the hole is broken, so that the nut is more convenient to drive into the furniture; a plurality of triangular pyramid 5 break a plurality of grooves with the inner wall in hole on the furniture, squeeze into downtheholely gradually along with the nut, a plurality of triangular prism 6 insert a plurality of inslots along the removal orbit of a plurality of triangular pyramids 5, so a plurality of triangular prisms 6 insert the inslot that a plurality of triangular pyramids 5 broke open, thereby increased the frictional force of nut and furniture, triangular prism 6 and triangular pyramid 5 card are gone into in the furniture in addition, make nut and screw cooperation be, the nut is difficult by the rotatory and not hard up of screw.

Be equipped with rubber circle 7 in the annular 4, rubber circle 7 is around on midbody 2 and is bonded with midbody 2, has inlayed on the rubber circle 7 and has placed the bag 8, places the bag 8 and is equipped with hollow chamber 9 that holds, holds and is equipped with glue 10 in the chamber 9, is equipped with on the midbody 2 and holds the through-hole 11 that the chamber 9 corresponds.

When the nut is driven into furniture, practical sharp needles and other objects pass through the through hole 11 to pierce the placing bag 8, so that the glue 10 flows out of the accommodating cavity 9, the glue 10 flows in the ring groove 4 and connects the rubber ring 7, the nut and the furniture together, so that the nut is firmly fixed on the furniture, and the nut is not easy to loosen due to the rotation of the screw when the screw is matched with the nut; the glue 10 is an epoxy adhesive.

The outer wall of the rubber ring 7 is provided with a plurality of rubber bulges 12, and the rubber bulges 12 extend out of the annular groove 4.

When the nut is driven into the furniture, the rubber bulges 12 on the rubber ring 7 are abutted against the furniture, so that the friction force between the nut and the furniture is increased, the nut and the furniture are connected more firmly, and the nut is not easy to loose under stress.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
