The present invention is related to a quick-release structure for a display, and more particularly to a quick-release structure for quickly assembling and disassembling a stand and a display.
For an all-in-one computer (AIO, All-in-One) a host is mainly provided on a display, and then the display is combined with the top of a stand through a locking structure provided on the back of the display. In this way, the display is supported by the stand, so that the display can be used on the desktop or flat surface. In this way the connection of the display with the stand through the locking structure makes it very inconvenient and more time-consuming to proceed the assembling and the disassembling.
For example, the Chinese Utility Model Patent entitled with “A screen support structure for easy assembling and disassembling” with No. CN103388729 has disclosed a feasible solution, which includes a stand and a coupling frame. The coupling frame is pivotally connected with the stand, and the coupling frame includes a fixing part and a buckle plate that is connected with the fixing part and can be moved elastically relative to the fixing part. The buckle plate is provided with a buckle part, and the fixed part is provided with a positioning part. When the stand is to be assembled and combined with a screen, the positioning part of the fixing member is first inserted into the positioning part on the back of the screen, and then the buckle part on the buckle plate is pressed into a joint part buckled on the screen to complete the assembling, such that the stand and the screen can be easily and quickly assembled or disassembled. Moreover, referring to the structures disclosed in the Chinese Patent entitled with “Racks with quick loading and unloading function” with No. CN201036450Y and in the Chinese Patent entitled with “Vertical Lifting Device” with No. CN210567151U, they are different from that in the Chinese Utility Model Patent with No. CN103388729, while they all have the function of quickly assembling or disassembling the stand and screen.
By means of the structure of the above-mentioned patent with No. CN103388729, it is indeed possible to quickly complete the assembling of the coupling frame and the display, but too many components are required in this patent, which is not conducive to cost reduction. In terms of rotational positioning, the positioning structure of “pin or steel ball plus spring” used in the CN201036450Y requires precise manufacturing and positioning. Any error would easily cause the display to shake and tilt. Furthermore, the three patents with No. CN103388729, No. CN201036450Y and No. CN210567151U all have the buckle arranged on the circumferential side, which is not only abrupt but also easy to cause damage to the devices of these patents or bring injury to users. Accordingly, in order to improve above technical problems, the present invention is provided.
One object of the present invention is to provide a quick-release structure for a display, which can overcome the problem that too many small components are required in patent with NO. CN103388729, that is, which can effectively decrease the number of required components to reduce production costs. Furthermore, in the present invention, the “first buckling portion” and the “second buckling portion” are provided at corresponding positions to facilitate the corresponding hooking, and the “first buckling portion” and the “pushing portion” are combined to facilitate simultaneous action, such that the quick-release structure of the present invention can be rotated synchronously with the display and the stress can be shared. Moreover, the “first buckling portion” is stored in the “housing of the top base of the stand”. Different from the conventional three patents of No. CN103388729, No. CN201036450Y and No. CN210567151U, where the buckle is arranged on the circumferential side, the arrangement of the buckle arranged on the circumferential side can make it more convenient to proceed the assembling and disassembling of the present invention, and also can protect the “first buckle portion” “and “second buckle portion” to avoid damage caused easily and abruptly to the devices of the present invention or brought injury to users.
One object of the present invention is to provide a quick-release structure for a display, so as to improve the positioning structure of the “pin or steel ball plus spring” with No. CN201036450Y, which requires precise manufacturing and positioning.
