Abstract

The utility model relates to a connecting structure for a wood part and a metal pipe. A section of end surface of the wood part inserted into the metal pipe is provided with a groove; one side of the groove is provided with a screw hole; the inner of the groove is fixedly provided with nut which is cooperated with a regulating screw, and the top part of the regulating screw can hold the other side of the groove; thus, the tightness of the connection structure of the wood piece and the metal pipe can be adjusted. When the utility model is used on a metal furniture, because the structure is loose and is convenient to be tightened in use, the service life of the structure can be prolonged.

Description

Ligneous piece and metal pipe connection structure

The utility model belongs to furniture manufacturing industry or building decorating industry metal tube and ligneous piece's linkage structure technical field.

The mode that existing metal tube is connected with ligneous piece, the general boundary dimension that all adopts ligneous piece to be inserted in metal section equals or all is a bit larger tham the interior hole dimension of metal tube, for example metal tube bed or metal tube table, chair, etc., its leg partly all adopts the metal solder assembly parts, after the size of ligneous piece's insertion is equal to or greater than metal tube endoporus inside dimension, can produce stationary fit between ligneous piece and the metal tube, prevent to produce and become flexible, but there is deficiency in the linkage structure of existing this metal tube and ligneous piece.At first be install to connect difficulty, the intensity of timber own is not high, be easy to peel off periphery when inserting, and boundary dimension is when being equal to or greater than the size of metal tube endoporus, and suit gets up quite wastes time and energy.Prior problem is, mounted furniture or fitting structure in use for some time, the insertion section of ligneous piece is pressed wearing and tearing, is produced distortion through hoop for a long time, causes loosening phenomenon to occur, has a strong impact on the life-span of its structure.

The utility model provides a kind of new ligneous piece and the linkage structure of metal tube for the deficiency that overcomes above-mentioned metal tube and ligneous piece's linkage structure just.

The purpose of this utility model is achieved by the following technical solution.

The end face that inserts section in ligneous piece has groove, at a sidetracking of groove one hole is arranged, and at the hole internal fixation one nut is arranged, and adopts adjusting screw to cooperate with nut, has an adjustment hole at metal tube and the screw head place that is in adjusting screw.Insert groove that the section end face opens in two in ligneous piece with the end face of ligneous piece.Adjusting screw push up the position groove on the another side on, be provided with a backing metal.

Further set forth content of the present utility model below in conjunction with drawings and Examples:

Fig. 1 is the utility model linkage structure schematic representation;

Fig. 2 be Figure 1A to the B-B sectional view.

It is the garden column type that present embodiment selects ligneous piece (1) and metal tube (2), and the external dimension of ligneous piece (1) equal the interior hole dimension of metal tube (2).The end face of ligneous piece has groove (3), is drilled with a hole (4) on a side rail product (1) of groove (3), and (4) internal fixation has a nut (5) in the hole.Its means of fixation can be bonding with binder, also can adopt the specialized nut that has helical tooth on the excircle.Make adjusting screw (6) by screw-thread fit between adjusting screw (6) and the nut (5) but precession or withdraw from.The position that is in adjusting screw (6) on metal tube (2) is in and has an adjustment hole (8), can regulate for the human screw-driver.Because groove (3) has been divided into two halves with ligneous piece (1) end face.On a side of end face, have screw hole (4), on opposite side, one backing metal (7) is set perpendicular to hole (4) shaft axis, face side is hindered on the unlikely direct top, pinnacle that had both guaranteed adjusting screw (6), make the ligneous piece of this side produce displacement on the whole again, promptly as long as produce loosening between ligneous piece (1) and the metal tube (2), only need to rotate precession adjusting screw (6) and withstand backing metal (7), a side of ligneous piece (1) end face will produce displacement, and the section of inserting it into is stuck in the metal tube tightly.

The utility model compared with prior art has Stability Analysis of Structures, service life Grow, be easy to the obvious advantage of adjustment connecting structure degree of tightness.

Claims

1, ligneous piece and metal pipe connection structure, one section by ligneous piece (1) is inserted in the metal tube (2), it is characterized in that: the end face that inserts section in ligneous piece (1) has groove (3), sidetracking at groove (3) has a hole (4), at hole (4) internal fixation nut (5) is arranged, adopt adjusting screw (6) to cooperate with nut (5), the screw head place that is in adjusting screw (6) on metal tube has an adjustment hole (8).

2, structure according to claim 1 is characterized in that, the groove of being opened (3) with the end face of ligneous piece (1) in two.

3, structure according to claim 1 is characterized in that, the another side on the groove (3) that adjusting screw (6) is withstood is provided with a backing metal (7).
