Technical Field
[0001] This utility model relates to the field of support equipment technology, and in particular to an easily adjustable tray support. Background Technology
[0002] To ensure stable support for the LCD screen and facilitate the smooth progress of testing, a support device is typically used. This device usually consists of a support body and a load-bearing structure. The load-bearing structure is connected to the support body and can stably place the LCD screen to meet the basic requirements of testing.
[0003] However, existing support devices have shortcomings in angle adjustment. The connection angle between the main body of the support and the load-bearing structure is fixed, and the tilt angle cannot be flexibly adjusted according to actual testing needs. When facing LCD screens of different sizes and models, the optimal observation angle also varies due to the different display characteristics of the LCD screens. The fixed-angle support makes it difficult for testing personnel to find a suitable observation position and to clearly and accurately observe the screen status of the LCD screen during the aging process. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an easily adjustable tray support, which aims to improve the problem that the connection angle between the main body of the existing support and the load-bearing structure is fixed and the tilt angle cannot be flexibly adjusted according to actual testing needs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: An adjustable tray support includes a first support rod, a fixing component slidably connected inside the first support rod, a third fixing block fixedly connected to the bottom end of the fixing component, a second support rod rotatably connected inside the third fixing block, a support body rotatably connected to one end of the second support rod, a first slider slidably connected inside the support body, a third support rod fixedly connected inside the first slider, an LCD screen disposed outside the third support rod, a first fixing rod disposed outside the LCD screen, a tray body disposed outside the first fixing rod, and both ends of the first fixing rod fixedly connected to the outside of the first support rod.
[0006] The above technical solution involves pressing the fixing component and sliding it inside the first support rod, thereby causing the third fixing block to move up or down, which in turn causes the second support rod to rotate, further causing the bracket body to rotate, and thus causing the LCD screen to rotate, thereby satisfying the customer's need to freely adjust the tilt angle.
[0007] Preferably, the fixing component includes a second slider, the outside of which is slidably connected to the inside of the first support rod, a protective sleeve is slidably connected to the outside of the second slider, the outside of which is slidably connected to the inside of the first support rod, the bottom end of the protective sleeve is fixedly connected to the top end of the third fixing block, and a first spring is provided at one end of the second slider.
[0008] Preferably, the fixing component further includes a first fixing block, the outside of which is slidably connected to the inside of the first support rod, and the inside of the first fixing block is threadedly connected to a first threaded rod, the bottom end of which is fixedly connected to the top end of the third fixing block.
[0009] Preferably, the third support rod is slidably connected to a first limiting block, one end of which is disposed outside the LCD screen.
[0010] Preferably, a third limiting block is fixedly connected to the bottom end of the first slider, and a second limiting block is slidably connected inside the third limiting block, with a second spring provided at one end of the second limiting block.
[0011] Preferably, the third limiting block is externally slidably connected to the inside of the bracket body, and the second limiting block is externally slidably connected to the inside of the bracket body.

[0013] Preferably, the outer side of the third slider is slidably connected to the inside of the first support rod, and the outer side of the third slider is slidably connected to the inside of the second fixing block.
[0014] This utility model has the following beneficial effects: 1. In this utility model, pressing the second slider slides the second slider. When the second slider is completely disengaged from the internal slot of the first support rod, the second slider slides upward, thereby driving the second support rod and the bracket body to rotate. The second slider is released to fix the position of the bracket body and the LCD screen, thus satisfying the customer's need to freely adjust the swing angle, making it easier to observe the status of the LCD screen and helping to detect aging quality problems in a timely manner.
[0015] 2. In this utility model, the third slider is pulled to slide the second fixing block inside the first support rod, and then the third slider is released. This allows the number of support layers to be quickly increased or decreased according to the actual number of screens, achieving efficient space utilization. Attached Figure Description

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] Example 1, refer to Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides: an easily adjustable tray support, including a first support rod 1, a fixing component 8 slidably connected inside the first support rod 1, a third fixing block 12 fixedly connected to the bottom end of the fixing component 8, a second support rod 2 rotatably connected inside the third fixing block 12, a support body 7 rotatably connected to one end of the second support rod 2, a first slider 3 slidably connected inside the support body 7, a third support rod 5 fixedly connected inside the first slider 3, an LCD screen 4 disposed outside the third support rod 5, a first fixing rod 6 disposed outside the LCD screen 4, a tray body 9 disposed outside the first fixing rod 6, and both ends of the first fixing rod 6 fixedly connected to the outside of the first support rod 1; Specifically, the first support rod 1 is the basic support component of the entire bracket, used to ensure the stability of the bracket. The third fixing block 12 is the intermediate component that transmits power to the fixing component 8. The second support rod 2 is used to drive the bracket body 7 to rotate to adjust the swing angle. The first slider 3 on both sides of the bracket body 7 slides to facilitate the adjustment of the position of the LCD screen 4 on the third support rod 5. The third support rod 5 is used to help fix the LCD screen 4 to prevent it from shaking. The first fixing rod 6 provides support for the LCD screen 4. The tray body 9 is used to carry other auxiliary items besides the LCD screen 4. The fixing component 8 is used to adjust and fix the swing angle of the bracket body 7 and the LCD screen 4.
[0020] Reference Figure 1 , Figure 3 and Figure 4 The fixing component 8 includes a second slider 801, the outside of which is slidably connected to the inside of the first support rod 1. A protective sleeve 802 is slidably connected to the outside of the second slider 801, and the outside of the protective sleeve 802 is slidably connected to the inside of the first support rod 1. The bottom end of the protective sleeve 802 is fixedly connected to the top end of the third fixing block 12. A first spring 803 is provided at one end of the second slider 801. Specifically, in this embodiment, the second slider 801 is composed of a square slider, a longer rectangular slider, and a cylindrical slider. The square slider slides inside the protective sleeve 802, while the longer rectangular slider and the cylindrical slider slide inside the first support rod 1. The cylindrical slider can also be pushed by the first spring 803 and locked in a slot opened inside the first support rod 1. The protective sleeve 802 is used to ensure the stability of the sliding process of the second slider 801, thereby achieving the effect of adjusting and fixing the angle of the LCD screen 4.
[0021] Example 2, refer to Figure 5 and Figure 6 The fixing component 8 also includes a first fixing block 804, the outside of which is slidably connected to the inside of the first support rod 1, and the inside of the first fixing block 804 is threadedly connected to a first threaded rod 805, the bottom end of which is fixedly connected to the top end of the third fixing block 12. Specifically, in this embodiment, the first fixing block 804 is cylindrical in the middle and has a handle on the outside for easy manual operation. The circular slot inside the first support rod 1 is used to allow the first fixing blocks 804 on both sides to be locked inside to fix the position of the third fixing block 12. The two sides of the first threaded rod 805 are relatively smooth to prevent the threaded groove from cutting the hand. A fixing block is set in the middle to connect the third fixing block 12. When the position needs to be adjusted, the first fixing block 804 is rotated away from the slot inside the first support rod 1, and the first threaded rod 805 is moved up or down to the appropriate slide. Then, the first fixing block 804 is rotated to lock into the slot inside the first support rod 1 to adjust the angle for easy observation of the state of the LCD screen 4.
[0022] Example 3, refer to Figure 7 , Figure 8 and Figure 9 Based on the above embodiments, this embodiment is used to solve the problem of rapidly increasing or decreasing the number of support layers, and is achieved through the following solution.
[0023] The third support rod 5 is externally slidably connected to a first limiting block 10, one end of which is located outside the LCD screen 4; the bottom end of the first slider 3 is fixedly connected to a third limiting block 15, the inside of which is slidably connected to a second limiting block 14, one end of which is provided with a second spring 16; the outside of the third limiting block 15 is slidably connected to the inside of the bracket body 7, and the outside of the second limiting block 14 is slidably connected to the inside of the bracket body 7; the bottom end of the first support rod 1 is fixedly connected to a second fixing block 11, the inside of which is provided with a third spring 17, one end of which is provided with a third slider 13; the outside of the third slider 13 is slidably connected to the inside of the first support rod 1, and the outside of the third slider 13 is slidably connected to the inside of the second fixing block 11; Specifically, the first limiting block 10 is used to limit and fix the LCD screen 4, preventing the LCD screen 4 from moving laterally during the testing process and ensuring its position is stable. The third limiting block 15 provides installation and sliding space for the second limiting block 14. It works with the slot between the second limiting block 14 and the bracket body 7 to limit the first slider 3 and the third support rod 5. The second spring 16 is used to provide a restoring force for the second limiting block 14. The third slider 13 is L-shaped, with one side used to hold the second fixing block 11 and the other side being a handle. The third spring 17 provides a restoring force for the third slider 13. A groove is provided on one side of the second fixing block 11 to hold the third slider 13. It works with the third spring 17 to realize the rapid assembly and disassembly of the multi-layer bracket.
[0024] Working principle: When the LCD screen angle needs to be adjusted, the second sliders 801 on both sides of the first support rod 1 are pressed and slid inside the protective sleeve 802 and the first support rod 1, so that the cylindrical side of the second slider 801 moves away from the cylindrical slot opened inside the first support rod 1. At the same time, the other end of the second slider 801 squeezes the first spring 803. When the cylindrical side of the second slider 801 is completely disengaged from the cylindrical slot opened inside the first support rod 1, the second slider 801 is slid upward and drives the protective sleeve 802 to slide inside the first support rod 1, thereby driving the third fixing block 12 to move upward, and thus driving the screen to move upward. The second support rod 2 rotates outside the third fixed block 12, further driving the bracket body 7 and the LCD screen 4 to rotate. When the second slider 801 moves to other slots opened inside the first support rod 1, the second slider 801 is released. The first spring 803 pushes one end of the second slider 801 to drive the cylindrical side of the second slider 801 to slide inside the first support rod 1 and fix the position of the second slider 801. At the same time, the positions of the bracket body 7 and the LCD screen 4 are fixed, so as to meet the customer's need to freely adjust the swing angle, so as to facilitate the observation of the screen status of the LCD screen 4 and help to detect aging quality problems in time. When adding a bracket layer, place the first support rod 1 to be added at the top of the first support rod 1, align the second fixing block 11 at the bottom of the first support rod 1 with the groove at the top of the first support rod 1, pull the third slider 13 to slide inside the first support rod 1, and then slide the second fixing block 11 into the groove inside the first support rod 1. After releasing the third slider 13, the third spring 17 pushes the third slider 13 to slide inside the first support rod 1 and the second fixing block 11, thereby locking the second fixing block 11 in place. When removing a bracket layer, pull the third slider 13 to slide inside the second fixing block 11 and the first support rod 1, and pull up the first support rod 1 to be removed, causing the second fixing block 11 to slide inside the other first support rod 1, thus removing a bracket layer. This allows for quick addition or reduction of bracket layers according to the actual number of LCD screens 4, achieving efficient space utilization.
