The retaining ring 2243 is clamped in the positioning groove and located in the cover 221 to stop the guide rod 2241 from moving further toward the pressing block 222, so as to prevent the guide rod 2241 from falling off from the cover 221. Specifically, the diameter of the retaining ring 2243 is larger than the caliber of the through hole.

Guide bar 2241 is along the direction of its self axis promptly, and one end sets up in spacing groove 2222, with limiting plate 2223 butt, the other end passes through the backstop of retaining ring 2243, realizes the spacing at guide bar 2241 both ends.

The installation method of the power box 2 and the display screen frame 1 is as follows:

the power supply box 2 is close to the display screen frame 1 in a direction parallel to the display screen frame 1, so that the fastening structure of the power supply box 2 is fastened with the fastening block 13 on the display screen frame 1, the locking head 14 is fastened in the limiting part 2237, and the power supply box 2 and the display screen frame 1 are quickly installed.

Since the elastic member 224 is disposed between the pressing block 222 and the cover 221, when the lock head 14 is installed, the lock plate 223 is moved by pressing the lock head 14, so that the lock head 14 firstly passes through the passing portion 2236 of the lock hole 2231, and after the lock head passes through the passing portion 2236, the lock plate 223 is rebounded by the elastic force of the elastic member 224 to position the lock head 14 at the position of the position-limiting portion 2237, thereby achieving the position limitation.

The pressing block 222 can also be pressed to make the pressing block 222 approach the cover 221, at this time, the lock head 14 directly passes through the passing portion 2236, then the pressing block 222 is released, the pressing block 222 is separated from the cover 221 by the elastic force of the elastic member 24, and the limiting portion 2237 moves to the lock head 14 to limit the lock head 14.

The method for disassembling the power box 2 and the display screen frame 1 is as follows:

the pressing block 222 of the quick lock 22 is pressed by an external force, so that the locking plate 223 moves towards the direction close to the cover 221, that is, the passing portion 2236 moves to the locking head 14, at this time, the locking head 14 is separable from the quick lock 22, and the power supply box 2 is separated from the display screen frame 1, so that the disassembly can be realized.

In other embodiments, the upper and lower ends of the power box 2 can be connected to the display frame 1 by using the quick locks 22. The specific setting can be according to actual need.

the utility model provides a quick lock includes the lid, presses down piece and jam plate. The cover body is provided with a containing groove and a through hole which runs through the two sides of the cover body, and the through hole is communicated with the containing groove. The lock plate is provided with a lock hole, the lock hole comprises a through part for the lock head to pass through and a limiting part for limiting the lock head, and the through part is communicated with the limiting part; the locking plate is inserted in the accommodating groove, and the locking hole is communicated with the through hole; the jam plate is connected with according to the briquetting, and is close to or keeps away from the lid along with according to the briquetting, and the line of passing through portion and spacing portion extends along the moving direction who presses the briquetting to make passing through portion and spacing portion can remove respectively to tapered end department. When the tapered end is located spacing portion, the power pack is connected with the display screen frame, and when the tapered end is located the portion of passing through, the power pack can be disconnected with the TV screen frame to realize quick installation and dismantlement, improved the efficiency of dismouting, satisfy on-the-spot quick assembly disassembly's requirement.
