Description

[Technical field]

[0001] The invention relates to a watch key, in particular to a double-material combination watch key which is easy to be colored, easy to be processed with CD grains and not easy to be deformed. [Background technology]

[0002] Currently, there are mainly two types of metal watch buttons: aluminum alloy watch buttons and stainless steel watch buttons. Among them, the material of aluminum alloy watch buttons is relatively soft, and long-term use will cause the button stem of the watch buttons to deform, affecting the use effect and the overall appearance of the watch; the material hardness of stainless steel watch buttons is high, and it is difficult to process CD patterns on the stainless steel surface, and it is difficult to color stainless steel watch buttons; the installation structure of the watch buttons of some watches is not stable enough, and the watch buttons or the watch button caps are prone to falling off after long-term use. [Summary of the invention]

[0003] The purpose of the present invention is to solve the above problems existing in the current metal watch buttons and to provide a double-material combination watch button.

[0004] The present invention is achieved through the following technical scheme: a dual-material combination watch button, including a button cap and a button rod, the key cap and the button rod are made of different materials, a cylindrical mounting cavity is provided inside the button cap, the button rod is cylindrical, the front end of the button rod is inserted and engaged in the cylindrical mounting cavity of the button cap by interference fit, and the top of the button rod is bonded to the bottom of the cylindrical mounting cavity of the button cap by glue dispensing.

[0005] Furthermore, the key cap material is aluminum alloy.

[0006] Furthermore, the button rod is made of stainless steel.

[0007] Furthermore, the inner wall of the cylindrical mounting cavity of the button cap is provided with a circle of bosses for extrusion interference fit, and the bosses are provided with an inclined surface at one end of the button rod to facilitate the insertion of the button rod, and the bosses are fastened and pressed on the side wall of the button rod through an extrusion process.

[0008] Furthermore, the top of the key cap is provided with a CD pattern, and the outer edge of the top of the key cap is provided with a beveled highlight.

[0009] Furthermore, the CD groove interval is 0.03 mm.

[0010] Furthermore, the button cap is electro-dyed.

[0011] Furthermore, the top of the button cap is electro-dyed red 1795C, and the rest of the button cap is electro-dyed black.

[0012] Furthermore, the button rod is a T-shaped column, and the front end of the button rod is a larger cylindrical structure than the rear end of the button rod.

[0013] The beneficial effects of the present invention are: the aluminum alloy key cap and the stainless steel key rod are double fixedly assembled into a watch key through interference fit and glue dispensing, which has good fastening, stable structure, easy coloring, easy CD pattern processing, and not easy to deform. The watch key will not affect the use effect and the overall appearance of the watch due to long-term use, and the key cap will not fall off due to long-term use.
