Technical Field

The invention relates to a plate connecting fitting, in particular to a hidden two-in-one connecting piece.

Background

At present, a plate connecting piece of furniture or a cabinet consists of two or three parts, a constructor has complex working procedures when mounting, firstly strikes an embedded part into a bottom plate hole, then mounts a pull rod and an eccentric part, and finally screws are tightened to lock the two plates. The embedded parts are driven into the holes by brute force during installation, so that the hole walls are easily damaged, and the embedded parts are not firm; and a large gap is generated between the two plates if the screw is not locked. Chinese patent CN212928418U discloses a hidden two unification connecting piece, sets up the joint piece of a plurality of round platform forms at the connecting piece both ends, predetermines the joint groove on panel during the use, inserts the joint inslot with the connecting piece both ends, utilizes the frictional force between joint piece and the joint inslot wall to lock two panels. The technical scheme has high requirements on the size precision of the clamping groove and the clamping block and low fault-tolerant rate.

Disclosure of Invention

The invention solves the technical problem of providing a hidden two-in-one connecting piece, wherein the two ends of the connecting piece are provided with accommodating grooves, and fixing columns are inserted into the accommodating grooves to expand the clamping part, so that the clamping part and plates are mutually extruded, and the connection of the two plates is realized.

The technical scheme adopted by the invention for solving the technical problems is as follows: a hidden two-in-one connecting piece comprises a connecting body; the connecting body comprises a connecting part in the middle and clamping parts at two ends; sawteeth are arranged on the outer sides of the clamping parts at the two ends; the device also comprises a fixing column; one end of the clamping part, which is far away from the connecting part, is provided with a containing groove matched with the fixing column; the fixing column is in interference fit with the accommodating groove.

Further, the method comprises the following steps: a circular groove is arranged between the clamping portion and the connecting portion.

Further, the method comprises the following steps: the bottom of the fixed column is conical, and the top of the conical fixed column is provided with a ball body.

The invention has the beneficial effects that:

1. the fixing column is inserted into the accommodating groove and in interference fit with the accommodating groove, and the clamping portion is propped open, so that the clamping portion and the mounting counter bore in the plate are mutually extruded, and the connection is firm.

2. The outer side of the clamping part is provided with the sawteeth, so that the plate can be more powerfully grasped, and the drawing force is increased.

3. Set up the circular slot between connecting portion and the joint portion, the joint portion of being convenient for struts.

Detailed Description

For the purpose of enhancing the understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.

Examples

As shown in fig. 1 to 3, a hidden two-in-one connector includes a connecting body 1; the connecting body 1 comprises a connecting part in the middle and clamping parts at two ends; sawteeth 11 are arranged on the outer sides of the clamping parts at the two ends; the device also comprises a fixing column 2; one end of the clamping part, which is far away from the connecting part, is provided with an accommodating groove 12 matched with the fixing column 2; the fixing column 2 is in interference fit with the accommodating groove 12.

On the basis, a circular groove 13 is arranged between the clamping portion and the connecting portion.

On the basis, the bottom of the fixed column 2 is conical, and a sphere is arranged at the top of the conical shape.

When the connecting piece is actually used, counter bores are preset on the transverse plate 3 and the vertical plate 4, the cross-sectional areas of the transverse counter bores 31 on the transverse plate 3 and the vertical counter bores on the vertical plate 4 are the same as the cross-sectional area of the connecting piece, and the connecting piece 1 can be exactly accommodated in the depth; clamping the fixing column 2 in the accommodating groove 12, respectively placing two ends of the connecting piece 1 into the transverse counter bore 31 and the vertical counter bore 41, extruding the two plates to enable the two plates to approach, and expanding the clamping part by a sphere at the top of the fixing column 2; when two panels are tightly pressed, the fixing column 2 is completely inserted into the containing groove 12, the clamping part is slightly unfolded, the sawteeth tightly clamp the inner wall of the counter bore, and the transverse plate 3 and the vertical plate 4 are tightly connected.

The containing groove 12 is the same as the fixed column 12 in shape, the opening end is conical, the inside is spherical, and after the fixed column 2 is completely inserted into the containing groove 12, the sphere of the fixed column 2 is clamped by the spherical groove inside, so that the fixed column 2 can be prevented from being separated.

The above embodiments should not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent transformations fall within the protection scope of the present invention.
