Abstract

The utility model relates to an expansive plate type furniture connector, which is characterized in that the connecting rod is used together with the expansion piece; the bottom end of the metal connecting rod is provided with external threads; a cruciform slot is arranged at the center of the upper hemisphere, and a slender neck is arranged between the hemisphere and the columniform part of the connecting rod; a hood is arranged at the top end of the nylon plastic expansion piece, the slender connecting part is the neck and consists of a plurality of radial strips, with the length same as that of the equant segment of the connecting rod. The design adopts the principle of built-in expansive fastening, with screw threads arranged on the external wall of the strip plate of the expansion piece, the frictional resistance with the hole wall is increased; the hood of the expansion piece extends to form a neck which clamps the neck of the connecting rod by the square to perform the self-locking function; the radial strips are capable of wrapping the connecting rod inserted inside without gaps in the hole wall, thereby the linking is closer and the plate surface is avoided to be wetted. The significant characteristics of the linking mode is that the assembled plate type furniture has no exposed hole, the appearance is more delightful, the connecting rod and the hole wall are connected more compactly, and the furniture is more durable.

Description

Expansion plate fitment link

Technical field

The utility model relates to the five metals parts in the processing industry, furniture link.

Background technique

Domestic at present, abroad in plate fitment combination, all adopt three-in-one formula link (to see that Fig. 1 a) carries out be connected (seeing Fig. 1 b) between plate and the plate always.There is thin neck connecting rod upper end for the ailhead shape among Fig. 1 a, and lower end, the big footpath of bar another part that spins: this part external diameter is greater than connecting rod and outside thread is arranged, and there is the groove of through diameter the bottom surface.The 3rd part is hat, diameter 15mm, and its circular surfaces has the cross indenture, and the wall of circle has the gap of axial commentaries on classics circumference, and gradually narrow along perisporium.Connecting rod and external thread piece screw in the hole of the vertical insertion in back level board and also rivet with hammering into shape during installation, riser thickness face has the endoporus that is parallel to wall, nose end is the macropore that penetrates thickness of slab, connecting rod inserts the wall endoporus, thin neck is exposed in the macropore, the cap gap is inserted along connecting-rod cap, and tighten with screw-driver, make the narrow end of cap perisporium gap prop up the hole, thereby make connecting rod be positioned at the center.The link macropore that this Placement all will leave the plate surface of plate fitment not only influences all sheet material moisture-sensitive of overall aesthetics, particularly hole of plate fitment, mouldy, distortion, so that the connecting rod hole wall ruptures, bearing plate comes off.

Summary of the invention

The purpose of this utility model provides a kind of expansion plate fitment link, makes composition board not expose the hole, has overcome the above-mentioned defective of combined plate type furniture.

Expansion plate fitment link is characterized in that connecting rod and expansion piece are used; There is outside thread metal connecting rod lower end, and the upper end hemisphere has cross recess, between hemisphere and body of rod cylindricality thin neck is arranged; Nylon expansion piece upper end is a cap, and the path that continues is neck and spreads apart and be the multi-disc bar shaped that bar length equates with the isometrical segment length of connecting rod.

The design adopts the fastening principle of built-in expansion, and the strip piece outer wall of expansion piece is designed to screw thread, increases the surface friction drag with hole wall; The expansion piece hat extends to neck, just in time blocks the connecting rod neck, plays self-locking action; The sheet shape of scattering can wrap the connecting-rod body that inserts wherein, makes hole wall not have the slit, in conjunction with tightr, prevents that wooden partition from making moist.The distinguishing feature of this Placement is to make combined plate type furniture not expose the hole, and more attractive in appearance, connecting rod combines tightr with hole wall, make furniture more durable.Assembly parts has only two.

Embodiment

Expansion plate fitment link is seen Fig. 6: it is characterized in that connecting rod 1 and expansion piece 2 are used; There is cross recess at hemisphere center, metal connecting rod 1 upper end, sees Fig. 2 b, and there is outside thread the lower end, sees Fig. 2 a, is thin neck between hemisphere and body of rod cylindricality, and edge, the big footpath of hemisphere and thin neck junction angle are greater than 90 °; Nylon expansion piece 2 upper ends are cap, and the path that continues is a neck, and spread apart and be the multi-disc bar shaped, and the bar shaped outer wall has screw thread, and bar length equates with connecting rod 1 isometrical segment length.

Fig. 4, Fig. 5 have showed that the design's link is in user mode: the helical thread portion of Fig. 5 connecting rod 1 vertically is screwed in the board plane hole, Fig. 4 Nylon expansion piece 2 places the wall endoporus of combined plate thickness, in the expansion piece 2 with the combined plate of connecting rod 1 vertical insertion, gravity lower connecting rod 1 hemispherical got in the cap of expansion piece 2, fit in two path position, neck forms self-locking.

Destructive test is carried out in above-mentioned design, and need rap vibrations with rubber mallet at the connecting rod access position of plate outer wall, use then greater than the power drawing of inserting connecting rod, can reach to split 5 times industry standard.

Claims
