Referring to fig. 11, further, the fixing base 10 includes a first positioning seat 17 and a second positioning seat 19 detachably connected, where the first positioning seat 17 includes a first positioning pillar 171 and a first positioning hole 173, the second positioning seat 19 includes a second positioning pillar 191 and a second positioning hole 193, the first positioning pillar 171 is inserted into the second positioning hole 193, and the second positioning pillar 191 is inserted into the first positioning hole 173, so as to fix the first positioning seat 17 and the second positioning seat 19.
In the present embodiment, the first positioning seat 17 and the second positioning seat 19 together form the accommodating space 12. Also, since the area of the middle frame assembly 210 and the bottom wall 11 of the stationary base 10 is large, that is, the contact area therebetween is large. At this moment, the flatness of the middle frame assembly 210 and the fixing base 10 is poor, the situation that the middle frame assembly 210 floats high or cannot be in complete contact may occur, centering and pressure maintaining fixation are poor when the screen 220 is attached and installed on the middle frame assembly 210 due to the accumulated errors of all parts, the fixing base 10 is set as the detachable first positioning seat 17 and the detachable second positioning seat 19, the flatness of each part can be good, and centering and pressure maintaining fixation are poor when the screen 220 is attached and installed on the middle frame assembly 210 due to the accumulated errors.
And, diapire 11 is all located to first reference column 171 and second reference column 191, and set up for the ball-type cylinder, and the tip of this first reference column 171 and second reference column 191 all is parallel and level and diapire 11, first locating hole 173 and second locating hole 193 are the ball-type hole, so set up and to make first locating seat 17 and second locating seat 19 realize dismantling the connection betterly, and be favorable to improving the plane degree, and then make things convenient for the laminating of screen 220 to install in centre of the center subassembly 210 fixed with the pressurize.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
