Technical Field

The invention relates to the technical field of die casting production, in particular to a corner connecting structure for a display cabinet.

Background

In the corner connecting structure of the existing display cabinet, two ends of the corner connecting structure are required to be connected with aluminum profiles 2 meters long; the part is usually made of pure aluminum, the production cost is high, and if the part is made of die-cast aluminum ADC12, the die-cast aluminum and the pure aluminum are difficult to weld;

1. the welding of die cast aluminum ADC12 is prone to generate residues or blowholes, so that pinholes tend to occur, or the molding is particularly unsightly, which is an objective cause of the die cast aluminum itself.

2. The die-casting aluminum ADC12 and pure aluminum 6063 are welded, the strength grade of the die-casting aluminum ADC12 and the pure aluminum 6063 are different, the melting points are different, smooth welding cannot be achieved, and the strength after welding is poor;

the pure aluminum and the pure aluminum are convenient to weld, and the process is mature; if all the pure aluminum is adopted for processing, the processing period is long and the production cost is very high.

Disclosure of Invention

In order to overcome the defects, the invention provides a corner connecting structure of a display cabinet, which can reduce the processing period and the production cost.

The technical scheme adopted by the invention for solving the technical problem is as follows: the utility model provides a corner connection structure of show cupboard, includes corner fitting and connecting piece, the both sides and the connecting piece of corner fitting are connected, the corner fitting is made for die-casting aluminium, and its both sides are equipped with the extension end that inserts in the connecting piece, the connecting piece is made for pure aluminium, and the connecting piece is the cavity form, and the one end internal weld fixed length of connecting piece is greater than the one end of the aluminium alloy of 2 meters, and the other end supplies the extension end of corner fitting to insert, the junction of corner fitting and connecting piece is serration structure the back of connecting piece is equipped with a plurality of fixed orificess, the front of connecting piece does not have the fixed orifices, and the surface that corresponds the extension end is equipped with bellied fixed column.

As a further improvement of the invention, a chamfer is arranged at the joint of the connecting piece and the corner piece, so that the connecting piece is convenient to be welded with an aluminum profile.

As a further improvement of the invention, the back surface of the connecting piece is provided with at least 5 fixing holes.

The invention has the beneficial effects that: according to the invention, pure aluminum is pre-embedded in a die-casting die by adopting the corner connecting structure of the display cabinet, and is formed by die-casting; the welding part is pure aluminum, and the rest parts are die-cast aluminum, so that the cost is greatly saved.
