[0001] This utility model relates to the field of display screen bracket technology, and in particular to a retractable liquid crystal display screen bracket. Background Technology
[0002] With the rapid development of information technology, LCD screens have been widely used in daily life, office work, entertainment, and many commercial fields. Different scenarios present diverse needs regarding the placement height of LCD screens. For example, in an office environment, users may need to adjust the screen height according to their posture and eye angle to achieve a more comfortable viewing experience and reduce neck fatigue; in presentation settings, the screen height also needs to be flexibly adjusted to accommodate the viewing needs of different audiences.
[0003] Currently, while some existing LCD monitor stands on the market offer height adjustment, the adjustment methods are often inconvenient and inflexible, and the stability of the adjustment is poor. Furthermore, most stands lack effective heat dissipation designs. During prolonged operation, the internal electronic components of the LCD monitor generate heat; if this heat cannot be dissipated in time, it will lead to performance degradation and a shortened lifespan. In addition, LCD monitors typically require the connection of various data cables. These cables, if scattered haphazardly, not only affect aesthetics but are also prone to tangling and damage, and existing stands rarely consider the issue of cable management.
[0004] Therefore, this application provides a retractable LCD screen bracket to solve the above-mentioned technical problems. Utility Model Content

[0034] like Figure 1-4As shown, an embodiment of this utility model provides a retractable LCD screen bracket, including a base 1. A vertical support column 2 is fixed to the upper surface of the base 1. A movable block 3 that can be raised and lowered is fixed to the top of the support column 2, and a cylinder 4 is fixed to the middle of the support column 2. The shaft of the cylinder 4 fixes the movable block 3 to form a vertical extension and retraction drive. A power block 5 is fixed to the bottom of the support column 2, and the power block 5 is electrically connected to the cylinder 4. In a specific implementation, a vertical sliding groove 201 is opened at the top of the support column 2. The movable block 3 is slidably installed in the sliding groove 201, and a vertical limiting post 202 is fixed in the sliding groove 201. A limiting hole 301 is opened in the middle of the movable block 3 for the limiting post 202 to pass vertically through.
[0035] Meanwhile, a mounting bracket 6 for fixing the LCD screen is installed at one end of the movable block 3. The edge of the mounting bracket 6 is provided with a heat dissipation groove 601, and the middle of the mounting bracket 6 is provided with a heat dissipation air duct 602 that communicates with the heat dissipation groove 601. A cooling fan 7 that communicates with the heat dissipation air duct 602 is installed at the other end of the movable block 3, forming an active heat dissipation mechanism.
[0036] In addition, fixing plates 605 are evenly fixed along the edge of the fixing frame 6. The end of each fixing plate 605 has a fixing hole 606 for fixing the LCD screen, and a rubber ring 607 is fixed around the edge of the fixing hole 606. Therefore, when the LCD screen is fixed with bolts using the fixing hole 606, active heat dissipation can be further achieved using the heat dissipation groove 601 and heat dissipation duct 602, which is beneficial for the long-term stable operation of the LCD screen. In specific implementation, a fixing block 603 is fixed to the end of the fixing frame 6 away from the heat dissipation duct 602. The fixing block 603 is horizontally inserted into the movable block 3, and a fixing bolt 604 for fixing the fixing block 603 is provided on the movable block 3.
[0037] The bottom of the movable block 3 is fixed with a take-up frame 302. The lower end of the take-up frame 302 has a take-up groove 303 with an opening on one side, and a downward-facing limiting cover 304 is elastically installed at the top of the take-up groove 303. The top of the limiting cover 304 is provided with three elastic elements 305, which are fixed to the top wall of the take-up groove 303. In specific implementation, the elastic elements 305 include springs.
[0038] The working principle provided by this utility model is that the retractable LCD screen bracket can be used to fix the LCD screen to the fixed frame 6 by using the fixing holes 606 and bolts. The height can be adjusted by driving the movable block 3 up and down through the cylinder 4, making it flexible to use.
[0039] When using the mounting bracket 6 to support the back of the LCD screen, the cooling fan 7 can be activated to work with the heat dissipation slots 601 and the heat dissipation ducts 602 to form a heat dissipation path. This allows the mounting bracket 6 to actively dissipate heat, which is beneficial for the long-term stable operation of the LCD screen. At the same time, when using the mounting bracket 6 to fix the LCD screen, the cable tray 303 and the limiting cover 304 can be used to store the data cable, making it convenient to use.
[0040] In summary, this device is not only flexible in use, allowing the height of the LCD screen to be adjusted as needed, but also facilitates heat dissipation of the LCD screen and storage of data cables, resulting in excellent overall performance.
