Description

Technical Field

[0001] The utility model belongs to the field of display screen front cover plates, in particular to a front cover plate for an electronic book display screen. Background Art

[0002] An e-book refers to a publication that digitizes information content such as text, pictures, sounds, and images, and a handheld reader that integrates a storage and display terminal and embeds or downloads digitized text, pictures, sounds, and images. In order to fix the display screen of the e-book, a corresponding front cover is required to realize the support operation of the e-book display screen. When the existing front cover is used, it is generally assembled by a snap connection method. However, the snap connection method is very easy to break due to the wrong prying position during disassembly, affecting subsequent assembly, and then causing the panel to lose effective limit on the display screen.

[0003] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it is revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model is created. A front cover plate of an e-book display screen is provided to solve the problem that the existing connection method of the clip is generally assembled by a snap connection, but the snap connection method is very easy to break due to the wrong prying position during disassembly, affecting subsequent assembly, and then causing the panel to lose effective limit on the display screen. Utility Model Content

[0004] The utility model provides a front cover plate for an electronic book display screen, which solves the problem in the prior art that the front cover plate generally adopts a snap connection method for assembly, but the snap connection method is easy to cause the snap to break due to incorrect prying position during disassembly, affecting subsequent assembly, and further causing the panel to lose effective limit on the display screen.

[0005] The technical solution of the utility model is implemented as follows: a front cover plate of an electronic book display screen includes a lever, the main body of the lever is arranged longitudinally, and a slider is fixedly connected to the outside of the lever, and the lever is provided at four locations, and two sliders are fixedly connected to the upper and lower sides of each lever in opposite directions, and the lever is slidably connected in a guide groove through the sliders fixedly connected on its outer surface, and a section of the lever is fixedly connected to a lever plate, and the lever and the lever together form a sliding structure, and the inner sides of the four levers are also fixedly connected to spring members, and the main body of the spring member is a telescopic structure with a spring, and the lever is fixedly connected in the guide groove through the spring member fixedly connected to the inner side thereof:

[0006] As a preferred embodiment, a limiting rod is fixedly connected to one side of the lever away from the spring member, and a thread is provided on the outer circumferential surface of the limiting rod away from the lever, a nut is screwed inside the limiting rod, and the nut and the limiting rod together form a limiting structure.

[0007] As a preferred implementation, the guide groove is opened in an inner position of a panel, and the panel is a front cover plate of an electronic display screen, a through groove is opened at the inner top of the panel, and a glass plate is embedded in the through groove.

[0008] As a preferred implementation, the glass plate and the panel together form a closed structure, and four guide grooves are provided on the outer side of the panel in opposite directions.

[0009] As a preferred implementation, a back plate is embedded inside the panel, and the size of the back plate is smaller than that of the panel.

[0010] As a preferred embodiment, a pad is fixedly connected to the top surface of the back plate, and there are two pads in total. The two pads are fixedly connected to the front and rear sides of the top surface of the back plate in opposite directions, and the back plate and the pads together constitute a supporting structure, and two limit holes are opened in a linear array inside the longitudinal component of the back plate, and the limit holes match the limit rod.

[0011] After using the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the utility model, a limiting rod is fixedly connected to the outside of the lever, so that when the panel and the back panel are assembled, the limiting rod fixedly connected to the outside of the lever can be inserted into the inner position of the panel and the back panel, and the assembly of the panel and the back panel can be completed by screwing the bolts. Compared with the traditional snap connection method, this design is more stable and avoids the situation that the snap is easily broken and affects normal use.

[0013] 2. In the utility model, a lever and a slider that can slide along the guide groove are provided, so that when the nut is removed from the limit rod, the panel and the back panel will not be directly separated. This design can avoid the situation where the panel is directly separated from the back panel when the nut limit is released, which may easily cause the internal components to fall. When unlocking is required, the lever needs to be moved to achieve the unlocking operation. This design can significantly improve the stability of the panel and the back panel during assembly.
