[0005] Advantageous Effects

[0006] The utility model provides a quick disassembly structure for a display backplane, which has the following beneficial effects compared with the prior art:

[0007] Related technicians place the backplane to be pressed on the mold and start the motor, so that the motor drives the reciprocating lead screw fixedly connected to its output shaft to rotate, so that the worm fixedly connected to the reciprocating lead screw rotates, so that the worm gear meshed with the worm rotates synchronously, so that the main shaft fixedly connected to the center of the worm gear rotates synchronously, so that the pulley A fixedly connected to the main shaft rotates, so that the pulley B rotates synchronously with the pulley A under the cooperation of the belt drivingly connected thereto, so that the auxiliary shaft fixedly connected to the center of the pulley B rotates, so that the eccentric wheel fixedly connected to the auxiliary shaft rotates synchronously, so that the push rod rotatably connected to the eccentric part of the eccentric wheel performs a circular motion, so that the push rod starts to push the pressing plate hinged thereto to press the backplane on the mold. At the same time, when the reciprocating lead screw rotates, the sliding cylinder threadedly connected thereto starts to perform a linear reciprocating motion along its connection with the frame, so that the sliding cylinder drives the support rod hinged thereto, so that the support rod starts to push the push rod hinged thereto, so that the push rod performs a circular motion with the connection with the frame as the fulcrum. When the pressing plate finishes pressing the backplane and starts to rise, the cross bar starts to contact the backplane, so as to disassemble the backplane from the mold through the cross bar.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0034] The so-called fixed connection in this application means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0035] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix the parts together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, and wedge pins), and they must be fastened properly.

[0036] (2) Non-detachable connections: mainly refer to welding, riveting, and mortise fitting, etc. Since for disassembly, forging, sawing, or oxygen cutting is required during maintenance or replacement, the spare parts generally cannot be reused. Meanwhile, during connection, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0037] As used in this application, the sliding connection refers to a component that can slide along a linear trajectory, and the hinged connection refers to a component that can rotate along an axial constraint.

[0038] In some cases, the sliding connection and the hinged connection as used in this application can also be damped, so that the component has the ability to maintain at the desired position.

[0039] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
