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 the connecting section 5 at the tail end is provided with an inwardly recessed embedding opening 7 as an embedding portion for connecting with the 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 rec...

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. Because the key body 1 and the decorative handle 2 are different metals, in order to make the casting connection more firm, a concave insertion opening 7 is also provided on the tail end connecting section 5 of the key body 1. When casting, the lower Melting point metal is poured into the insertion opening, thereby also snapping to maintain 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 insertion opening 7 is provided on the connecti...

Abstract

The decoration key includes key body and decoration handle connected together, the key body has back extended connecting section with embedding part in the tail, and the decoration handle has clamping part corresponding to the embedding part. When the key body has its connecting section is stretched into the decoration handle, the embedding part and the clamping part are clamped and connected. The decoration handle of low smelting point metal or alloy may be adhered to the key body after casting, or be cast directly onto the tail end of the key body. The present invention makes key possess decoration effect and personalized distinction effect.

Description

technical field [0001] The invention relates to a key, in particular to a decorative key with tail decorations and decorative effects. Background technique [0002] Existing keys are integrally formed with a key ring at the tail end of the key body. Although the key ring has a variety of styles and shapes, because it is integrally cast with the key body, a key can only have one key ring. . It has no decorative effect and no personality, and it is difficult to distinguish the same key when placed together. Contents of the invention [0003] The purpose of the present invention is to provide a decorative key, which not only makes the key itself have a decorative effect, but also can choose different shapes of decorations to distinguish different keys, and has a certain personalized identification function. [0004] The object of the present invention is also to provide a method for manufacturing the above-mentioned decorative key, which is used for preparing the above-ment...
