Embodiment
Below with reference to accompanying drawing, specific embodiment of the utility model is described in further detail.
as shown in Fig. 1 to 5, the touch panel unit 6 of a kind of embodiment, the touch-screen 61 that comprises rectangle, shell 1, the first buckle 64, the second buckle 65, the first holder 62, the second holder 63, the first screw 2, the second screw 5, shell 1 is provided with the first snap seats 1A, the second snap seats 1B, the first buckle 64, the second buckle 65, the first holder 62 and the second holder 63 stick on respectively on four angles of touch-screen 61, can adopt glue 67 or other adhesivess to realize pasting, the first buckle 64 and the second buckle 65 coordinate with the first snap seats 1A and the second snap seats 1B respectively, the first buckle 64 is provided with male plug button 64A, the second buckle 65 is provided with male plug button 65A, with difference fastening the first snap seats 1A and the second snap seats 1B, the first holder 62 is fixed on shell 1 by the first screw 2, the second holder 63 is fixed on shell 1 by the second screw 5.
Mobile phone also comprises built-in part 4, built-in part 4 is fixed in shell 1, for example fix by glue, built-in part 4 is provided with screw 4A, its direction can be along the sidewall direction perpendicular to shell 1, and the first holder 62 is provided with the first through hole 62A, and the first screw 5 passes the first through hole 62A and coordinates with screw 4A, like this, the first screw 5 is pressed on the first holder 62 on built-in part 4.
Shell 1 is provided with outer casing through hole, nut 2 is installed in outer casing through hole, can nut 2 be fixed on shell 1 by hot melt or the mode such as be press-fitted, the second holder 63 is provided with the second through hole 63A, the second screw 3 passes nut 2 and coordinates with the second through hole 63A, like this, the second screw 3 is fixed on shell 1, and the second holder 63 fixing (being figuratively speaking " extension ") is on the second screw 3.
In touch-screen 61 one side relative with shell 1, the edge of touch-screen 61 is bonding by double faced adhesive tape 66 and shell 1.
The process that touch-screen 61 is assemblied on shell 1 is as follows:
Male plug button 64A and the 65A of the first buckle 64 and the second buckle 65 are inserted respectively in the first snap seats 1A and the second snap seats 1B of shell 1 lower end, the touch-screen 61 that again edge is posted double faced adhesive tape 66 shell 1 of packing into, touch panel unit 61 clings on shell 1 by double faced adhesive tape 66;
Then, the second through hole 63A that screw 5 is passed the second holder 63 locks in the screw 4A that is fixed in the built-in part 4 in shell 1, and the second holder 63 is fixed on shell 1; Screw 3 is locked and passed the nut 2 that is fixed on shell 1, screw 3 will have enough length to be enough to make screw 3 can penetrate in the screw via hole 62A of the first holder 62, thereby the first holder 62 is fixed on screw 3.
Like this, when double faced adhesive tape 66 partial failure of the lower surface of touch-screen 61 (being touch-screen 61 one side relative with shell 1), touch-screen 61 still can be tightened up on shell 1 by the first buckle 64, the second buckle 65, the first holder 62 and the second holder 63, both guaranteed that touch-screen 61 firmly was fixed on shell 1, facilitate again touch-screen 61 is disassembled from shell 1, with convenient for maintaining.
