Description

Plug-in type fast-assembling furniture plate body connecting piece

Technical Field

The utility model relates to a adapting unit of furniture plate body, a plug-in type fast-assembling furniture plate body connecting piece that firmness is high, reliable and stable specifically says so.

Background

The plate body connecting piece is a common part for connecting and fixing the plate body of the existing furniture, and generally comprises three parts, namely an eccentric wheel, a connecting rod and a connecting head. The working principle is that the eccentric wheel rotates to drive the connecting rod and the connecting head to move to the joint of the plate bodies, so that the two plate bodies are connected together.

Chinese patent document CN201448321U discloses a plug-in type furniture connecting piece, which is fastened by matching a male buckle, a female buckle and a female opening to fix a thin plate and another plate together. However, this furniture connector structure has two significant technical drawbacks. Firstly, the connecting piece needs three buckle bodies which are sequentially sleeved to realize the fixation of two plate bodies, and when the machining errors of the three buckle bodies are overlapped, the condition that the three buckle bodies cannot be assembled easily occurs. Secondly, when the furniture connecting piece is installed, the secondary buckle needs to be inserted into the middle buckle, so that the end part of the middle buckle is buckled with the end part of the female buckle, the fixing capacity of the secondary buckle on the plate body where the secondary buckle is located is poor, and the situation of shaking after installation is easy to occur. In addition, the last installation step of the furniture connecting piece is to insert the sub-buckle, so a through hole needs to be formed in the plate body, namely, a hole is left in one surface of the plate body facing a user after the plate body is installed, and the attractiveness of the plate body is seriously affected.
