[0002] Liquid crystal display is a type of flat panel display, which is mainly used for screen display of television and computer. The advantages of this display are low power consumption, small size and low radiation. At the same time, when the liquid crystal display is placed on a horizontal surface for use, it is generally used in conjunction with a retractable fixed bracket so that the liquid crystal display can have the function of retractable adjustment during actual use;

[0003] In the prior art, manual cooperation is usually required in the process of adjusting the liquid crystal display screen up and down by using the telescopic structure provided on the back. However, considering the lack of effective limit operation in the telescopic structure in some cases, the liquid crystal display screen may easily be slightly offset to the left and right due to improper operation after the telescopic operation is completed. Subsequently, the liquid crystal display screen needs to be adjusted for offset, which brings some unnecessary troubles to the entire telescopic adjustment operation. Therefore, a liquid crystal display screen with a telescopic function is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A liquid crystal display screen with a telescopic function comprises a transfer back plate 1, a liquid crystal display screen body 2 is arranged at one side of the transfer back plate 1, a support block 3 is fixedly connected to the other side of the transfer back plate 1, a telescopic rod 4 is fixedly connected to one side of the bottom end of the support block 3, a limiting bracket 6 is fixedly connected to the other side of the bottom end of the support block 3, a spacer 7 is glued to the top position of the horizontal end of the limiting bracket 6, a guide groove 8 is provided at the vertical end of the limiting bracket 6, a slider 9 is provided on the inner side of the guide groove 8, a telescopic frame 5 is fixedly connected to one side end of the slider 9, a reinforcing support rod 10 is fixedly connected to the bottom end of the telescopic frame 5, and side openings 14 are respectively provided at the front and rear ends of the liquid crystal display screen body 2, and a buckle plate 15 is provided on one side of the inner side of the side opening 14.

[0020] like Figure 1 As shown, the top and bottom sides of the adapter back panel 1 are respectively fixedly connected with side clamping plates 11, and the LCD display body 2 and the side clamping plates 11 are fixedly connected by bolts. By providing two sets of upper and lower side clamping plates 11, this structural setting will facilitate the entire display tool to be quickly fixedly connected to the adapter back panel 1 through two sets of buckle plates 15.

[0021] like Figure 1 and Figure 2 As shown, the lower half of the telescopic rod 4 extends to the interior of the telescopic frame 5, and a sliding connection is set between the telescopic rod 4 and the telescopic frame 5. The connection between the adapter back plate 1 and the support block 3 forms a "T"-shaped structure. Under the setting of the sliding connection, the telescopic rod 4 can be freely stretched outward from the inside of the telescopic frame 5, which can facilitate the up and down telescopic adjustment operation of the entire display tool; the outer shape of the limiting bracket 6 is set in an "L"-shaped structure, and a card slot that is engaged with the horizontal end of the limiting bracket 6 is opened at the bottom position of the liquid crystal display screen body 2. The limiting bracket 6 is slidably connected by a guide groove 8 and a slider 9. When the display tool is telescopically brought out of the telescopic frame 5 through the telescopic rod 4 to achieve the purpose of telescopic adjustment, the sliding cooperation between the guide groove 8 and the slider 9 will provide a guiding and limiting effect during the telescopic process of the actual tool.

[0022] like Figure 1 and Figure 3As shown, the front and rear ends of the adapter back plate 1 are respectively fixedly connected with side card frames 12, and the end of the side card frame 12 away from the adapter back plate 1 is slidably connected with a movable support rod 13, and a buckle 16 is fixedly connected to one side of the movable support rod 13. The front and rear positions of the buckle 16 and the buckle plate 15 are relatively set, and the sizes of the longitudinal ends of the buckle 16 and the grooves formed between the buckle plate 15 and the side opening 14 are matched with each other. After the adapter back plate 1 is fixedly connected to the liquid crystal display body 2, the front and rear groups of movable support rods 13 can be pulled outwards respectively, so that the buckle 16 provided on one side end can be inserted into the groove and hooked on the buckle plate 15 after aligning with the groove formed between the buckle plate 15 and the side opening 14. At this time, the locking structure composed of the side card frame 12, the movable support rod 13 and the buckle plate 15 can make the connection between the adapter back plate 1 and the liquid crystal display body 2 more stable and tight.

[0023] Working process: The electric energy required for the startup and operation of the display tool in the utility model all comes from an external power supply. When the entire LCD screen is needed, first, the entire display tool completes the up and down telescopic adjustment operation in advance. After ensuring that the entire display tool is stably connected to the external power supply and the external output terminal, the entire display tool can be turned on by pressing a button to perform the corresponding screen display operation. At the same time, when the entire display tool needs to be telescopically adjusted up and down, the bolt fixings that fasten the telescopic rod 4 can be screwed outward for a distance, and then, with the cooperation of the guide limiting structure, the support block 3 is manually pulled upward so that the telescopic rod 4 can be pulled out from the inside of the telescopic frame 5 to achieve extension, and finally, it is telescoped to a suitable height position, and the telescopic rod 4 is tightened by resetting and screwing the screw fixings. After being firmly limited, the display tool connected to the support block 3 can quickly complete the telescopic adjustment operation. When the upward and downward telescopic adjustment operation of the entire display tool is realized through the cooperation of the telescopic rod 4 and the telescopic frame 5, after the support block 3 is firmly connected to the LCD screen body 2 through the adapter back plate 1, the horizontal end of the limiting bracket 6 will be engaged and connected to the LCD screen body 2. As the telescopic rod 4 is pulled out from the inside of the telescopic frame 5, in the process of cooperating with the entire display tool to realize the telescopic adjustment operation, the limiting bracket 6 that provides a stable support from the bottom position of the LCD screen body 2 will use the sliding cooperation between the guide groove 8 and the slider 9 to provide a guiding and limiting function when the display tool is telescopically adjusted, thereby preventing the display tool from having a slight position deviation after completing the telescopic adjustment operation.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
