[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0034] Embodiment 1: A backlight guide plate that is easy to install, see Figures 1 to 4 , comprising a backlight guide plate 2 and a connecting structure 1;

[0035] Backlight light guide plate 2; two connection structures 1 are respectively arranged at two ends of the backlight light guide plate 2;

[0036] The connection structure 1 includes a fixing bar 302 and a connecting bar 301;

[0037] The fixing strip 302 is fixed on the inner wall of the back frame; the connecting strip 301 is fixed on the side end of the backlight guide plate 2; wherein the connecting strip 301 is in contact with and cooperates with the fixing strip 302; wherein the front and rear ends between the two connecting strips 301 are respectively arranged with spring pieces 3, and the spring pieces 3 are pressed against the connecting strip 301 and are in contact with and cooperate with the fixing strip 302.

[0038] The utility model provides a fixing strip 302, a connecting strip 301 and a spring sheet 3, and has the advantage of positioning the backlight guide plate 2 by pressing the connecting strip 301 against the fixing strip 302 through the spring sheet 3, thereby solving the problem of additional reinforcement required for the light guide plate when inserted into the back frame, which increases the number of installation steps.

[0039] Specifically, the spring piece 3 is designed with an arc-shaped structure, and the arched end of the spring piece 3 is facing upward; the arc-shaped spring piece 3 can better cooperate with the curved installation of the backlight guide plate 2, and the arc-shaped spring piece 3 can better resist the connecting strip 301; wherein, the arched end of the spring piece 3 does not exceed the backlight guide plate 2, and does not affect the installation of other components on the backlight guide plate 2.

[0040] Furthermore, the upper and lower ends of the abutting side of the connecting strip 301 are respectively configured as arc surfaces A3011, the upper and lower ends of the abutting side of the fixing strip 302 are respectively configured as arc surfaces B3021, and the middle section of the abutting side of the connecting strip 301 abuts and cooperates with the middle section of the abutting side of the fixing strip 302.

[0041] The utility model has the advantage that the arc surface A3011 and the arc surface B3021 are arranged so that when the bent backlight guide plate 2 and the spring piece 3 are installed and the fixing bar 302 and the connecting bar 301 are misaligned, the arrangement of the arc surface A3011 and the arc surface B3021 enables the fixing bar 302 and the connecting bar 301 to abut against each other smoothly.

[0042] Furthermore, a clamping strip 303 is fixedly provided at the bottom of the middle section of the abutting side of the connecting strip 301 , and a clamping groove 3022 is provided at the bottom of the middle section of the abutting side of the fixing strip 302 , and the clamping strip 303 is plugged into and matched with the clamping groove 3022 .

[0043] The utility model has the advantage of further fixing the fixing bar 302 and the connecting bar 301 by providing the clamping strip 303 and the clamping slot 3022 after the fixing bar 302 and the connecting bar 301 are abutted against each other, thereby further maintaining stability.

[0044] It is worth noting that the top of the middle section of the abutting side of the fixing strip 302 is configured as an inclined surface 3023, wherein the inclined surface 3023 is inclined inwardly, so that the clamping strip 303 can be inserted into the clamping slot 3022 more smoothly along the inclined surface 3023.

[0045] Working principle: When using the device of the utility model, the fixing strip 302 is fixed on the inner wall of the back frame. When installing the backlight guide plate 2, the two connecting strips 301 are squeezed relative to each other so that the backlight guide plate 2 and the spring sheet 3 are moderately bent. The backlight guide plate 2 and the spring sheet 3 are placed into the back frame, and the two connecting strips 301 are also put into the back frame. The two connecting strips 301 are slowly loosened. Under the action of the spring sheet 3, the two connecting strips 301 move relative to each other until they abut against the two fixing strips 302. The card strip 303 is inserted into the card slot 3022 along the inclined surface 3023. At this time, the backlight guide plate 2 is kept horizontally opened, and the installation of the backlight guide plate 2 is completed, and the backlight guide plate 2 is positioned in the back frame.

[0046] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
