Embodiment Construction

[0007] During assembly, the five semicircular special structures in the button are snapped into the five clamping columns in the back cover. This special semicircular structure can play a role of tight fit, so the button part can be tightly fitted on the back cover. in the button hole of the cover.

[0008] In practice, the present invention can still be closely matched after reducing the heat-melting process, and this pure matching method can be quickly installed and disassembled, which brings great convenience to assembly and maintenance.

Abstract

The invention provides a key without the requirement of hot melt, consisting of a key and a rear cover; the structure of the rear cover is matched with the key; five plastic rubber clamp columns are arranged below a key hole at the internal side of the rear cover; the key is provided with five special semiround structures which can be closely matched with the five clamp columns; the close matching strength needs no hot melt, thus reducing the working procedure during the assembly process and increasing the matching compactness; the key of the invention can be disassembled and maintained.

Description

technical field [0001] The invention relates to a digital photo frame, in particular to a button of the digital photo frame. Background technique [0002] At present, the structural mode of the digital photo frame is relatively simple, such as using the same method of hot-melting to fix the key in the structure of the key. This hot-melt fixation method is cumbersome, requires the use of hot-melt tools, and is not easy to disassemble and maintain. Contents of the invention [0003] The present invention aims at the defects of the prior art, and provides a closely fitted button device. [0004] In order to achieve the above object, the present invention takes the following measures to achieve: [0005] A button without hot melt, which is composed of a button and a matching back cover. It is characterized in that the structure of the back cover is matched with the button. There are 5 plastic posts under the button hole inside the back cover, and on the button. There are 5 ...
