Embodiment 1
[0036] Such as image 3 As shown, the rear end of the key body 1 in this embodiment is no longer provided with a common integrally formed handle, but a connecting section 5 extending backward. The key body 1 is formed by casting copper material. Wherein, an inwardly concave square opening 7 is provided on the connecting section 5 at the tail end as an embedding part for connecting with a decorative handle. The decorative handle 2 of the present embodiment is a three-dimensional shape cast by the above-mentioned 200-400 degrees Celsius low-melting point alloy (tin, tin-lead alloy, zinc-magnesium alloy, etc.), and the three-dimensional shape is relatively bonded by two decorative sheets. made. The three-dimensional shape is cast in two pieces during casting, the outer surfaces of the front piece and the back piece can be cast into different shapes, and the inner surfaces of the front piece and the back piece are used as bonding surfaces. On the bonding surface, a recess having...
Embodiment 2
[0044] Such as Figure 4 As shown, the basic structure and method of this embodiment are the same as those of Embodiment 1, the difference is the structure of the connecting section at the tail end of the key body 1 and the engaging structure of the two decorative pieces. An engaging hole 10 that runs through the key body is provided on the connecting section 5 at the end of the key body, and an engaging column 9 of a corresponding shape is provided on the bonding surface of the two decorative sheets, and the engaging column 9 passes through the engaging hole 10 during assembly. , so that the key body is firmly connected with the decorative handle.
Embodiment 3
[0046] Such as Figure 5 Shown is the sectional view of the decorative key of the present embodiment. The decorative handle 2 of this embodiment is formed by integral casting of a low-melting point alloy or metal, and the tail end connecting section 5 of the key body 1 is contained in the decorative handle 2 during molding. Since the key body 1 and the decorative handle 2 are made of different metals, in order to make the casting connection more firm, a concave engaging opening 7 is also provided on the tail end connecting section 5 of the key body 1. Melting point metal is poured into the snap-fit opening, so that the snap-fit also maintains the firmness of the connection.
[0047] The manufacturing process of this embodiment is as follows:
[0048] Firstly, the key body is prepared: the key body 1 is cast with copper, the end of the key body 1 is provided with an extended connection section 5 , and a concave engaging opening 7 is provided on the connection section 5 . ...
