Technical Field
[0001] This utility model relates to the field of screen lifting technology, specifically a stable lifting mechanism for screens. Background Technology
[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. The main body of a computer generally needs to be used in conjunction with a computer screen. The bottom of the computer screen is usually equipped with a support base, commonly known as a stand, which serves to support the computer screen.
[0003] In response, Chinese patent application number CN202120235566.8 discloses a computer screen stand with a lifting function, including a base, a rotating column structure of the base, an auxiliary fixing structure, a telescopic load-bearing structure of the base, and a quick-closing structure. The rotating column structure is installed on the upper surface of the base, the auxiliary fixing structure is installed on both sides of the rotating column structure, the telescopic load-bearing structure is installed at the top of the rotating column structure, and the quick-closing structure is installed on one side of the rotating column structure near its top. An anti-slip pad layer made of rubber is adhered to the bottom of the base using adhesive. The rotating column structure includes mounting plates and square columns, with two mounting plates provided. This utility model is simple to operate and convenient to use. After adjusting the angle of the computer screen, the screen is less likely to wobble and affect normal use. It also facilitates height adjustment of the computer screen, making it highly practical overall.
[0004] The base adjusts the screen angle by using a square column that can rotate on the base. However, in actual adjustment, the greater the tilt angle of the screen, the greater the adjustment angle of the square column. The center of gravity of the square column on the base will also shift forward, while the bottom of the square column is fixed on the base. During use, the device will tilt forward, affecting the user experience of the screen.
[0005] Therefore, in order to solve the above problems, a stable lifting mechanism for the screen is proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a stable lifting mechanism for a screen, in order to solve the problem mentioned in the background art where the base adjusts the screen angle by setting a square column that can rotate on the base. However, in actual adjustment, the greater the tilt angle of the screen, the greater the adjustment angle of the square column, and the center of gravity of the square column on the base will move forward. Since the bottom end of the square column is fixed on the base, the device will tilt forward during use, which affects the user experience of the screen.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a stabilizing lifting mechanism for a screen, comprising: a base;
[0008] An adjustment structure is installed on the top surface of the base. The adjustment structure includes a fixed frame, which is fixedly installed on the top surface of the base. A groove is formed on the surface of the fixed frame, and a slider is slidably installed on the inner side of the groove. A connecting block is fixedly installed on the top surface of the slider. A hand-operated rod is movably connected to the inside of the fixed frame through a bearing. A rotating arm is fixedly installed on the inner side of the connecting block through a fastening bolt. A guide groove is formed on the inner wall of the rotating arm, and a hand-operated threaded sleeve is movably installed on the top surface of the rotating arm through a bearing. A telescopic arm is inserted into the inner side of the rotating arm, and a guide block is fixedly connected to the outer wall of the bottom end of the telescopic arm.
[0009] Preferably, the slider is located inside the fixed frame, and the bottom surface of the slider is in contact with the top surface of the base.
[0010] Preferably, the hand-operated lever passes through the slider and is threadedly connected to the slider.
[0011] Preferably, the hand-threaded sleeve is fitted on the outside of the telescopic arm and is threadedly connected to the telescopic arm.
[0012] Preferably, the guide block is slidably mounted on the inner side of the guide groove, and the guide block and the guide groove cooperate with each other.
[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a slider and a fixed frame, the slider can move back and forth within the fixed frame, which can adjust the front and back position of the connecting block on the base, thereby realizing convenient adjustment of the center of gravity of the rotating arm on the base, improving the support stability of the base for the device, and ensuring the practicality of the device.
[0014] This invention features an adjustment structure. When the angle of the rotating arm needs adjustment, the fastening bolt can be unscrewed, and the rotating arm pulled, causing it to deflect inside the connecting block. After adjustment, the rotating arm can be screwed back on to fix its angle inside the connecting block, thus adjusting the screen angle. When the front-to-back position of the screen needs adjustment, the hand-operated threaded sleeve can be manually rotated. The hand-operated threaded sleeve is threadedly connected to the telescopic arm, and the telescopic arm is fixed inside the rotating arm through the cooperation of the guide block and guide groove. The telescopic arm cannot rotate inside the rotating arm. Therefore, rotating the hand-operated threaded sleeve will cause the telescopic arm to move up and down within the rotating arm, thus adjusting the front-to-back position of the screen to meet different usage needs. If the device becomes unstable due to the adjustment of the rotating arm angle and the front-to-back position of the screen, the hand-operated lever can be rotated. The hand-operated lever is threadedly connected to the slider. The rotation of the hand-operated lever will cause the slider to move back and forth inside the fixed frame, adjusting the front-to-back position of the connecting block on the base. This allows for convenient adjustment of the rotating arm's center of gravity on the base, improving the base's support stability for the device and ensuring its practicality.

[0023] A screen stabilization and lifting mechanism includes: a base 1;
[0024] An adjustment structure 2 is installed on the top surface of the base 1. The adjustment structure 2 includes a fixed frame 21, which is fixedly installed on the top surface of the base 1. A groove 22 is provided on the surface of the fixed frame 21. A slider 23 is slidably installed on the inner side of the groove 22. A connecting block 24 is fixedly installed on the top surface of the slider 23. A hand-operated rod 25 is movably connected to the inside of the fixed frame 21 via a bearing. A rotating arm 27 is fixedly installed on the inner side of the connecting block 24 via a fastening bolt 26. A guide groove 28 is provided on the inner wall of the rotating arm 27. A hand-operated threaded sleeve 29 is movably installed on the top surface of the rotating arm 27 via a bearing. A telescopic arm 210 is inserted into the inner side of the rotating arm 27. A guide block 211 is fixedly connected to the outer wall of the bottom end of the telescopic arm 210. The slider 23 can move back and forth within the fixed frame 21, which can adjust the front and back position of the connecting block 24 on the base 1, thereby realizing convenient adjustment of the center of gravity of the rotating arm 27 on the base 1, improving the support stability of the base 1 for the device, and ensuring the practicality of the device.
[0025] Furthermore, the slider 23 is located inside the fixed frame 21, and the bottom surface of the slider 23 is in contact with the top surface of the base 1. The slider 23 can move straight back and forth within the fixed frame 21, thereby adjusting the front and back position of the connecting block 24 on the base 1.
[0026] Furthermore, the hand-operated lever 25 passes through the slider 23 and is threadedly connected to the slider 23. Rotating the hand-operated lever 25 can drive the slider 23 to move inside the fixed frame 21, thereby enabling convenient adjustment of the front and rear position of the connecting block 24 on the base 1.
[0027] Furthermore, the hand-operated threaded sleeve 29 is fitted on the outside of the telescopic arm 210 and is threadedly connected to the telescopic arm 210. Rotating the hand-operated threaded sleeve 29 can drive the telescopic arm 210 to move up and down within the rotating arm 27, so as to realize convenient adjustment of the front and rear position of the screen to meet different usage needs.
[0028] Furthermore, the guide block 211 is slidably installed on the inner side of the guide groove 28. The guide block 211 and the guide groove 28 cooperate with each other. The guide block 211 and the guide groove 28 provide guidance and limit for the movement of the telescopic arm 210 inside the rotating arm 27, so as to prevent the telescopic arm 210 from rotating.
[0029] Working principle: When the angle of the rotating arm 27 needs to be adjusted, the fastening bolt 26 can be unscrewed and the rotating arm 27 can be pulled, so that the rotating arm 27 deflects inside the connecting block 24. After the adjustment is completed, the rotating arm 27 can be screwed back on, which can fix the angle of the rotating arm 27 inside the connecting block 24, thereby realizing the adjustment of the screen angle.
[0030] When the front and back position of the screen needs to be adjusted, the hand-threaded sleeve 29 can be manually rotated. The hand-threaded sleeve 29 is threadedly connected to the telescopic arm 210, and the telescopic arm 210 is fixed inside the rotating arm 27 through the cooperation of the guide block 211 and the guide groove 28. The telescopic arm 210 cannot rotate inside the rotating arm 27. Therefore, after rotating the hand-threaded sleeve 29, the telescopic arm 210 will move up and down inside the rotating arm 27, thereby realizing the adjustment of the front and back position of the screen to meet different usage needs.
[0031] When the device becomes unstable due to the adjustment of the angle of the rotating arm 27 and the adjustment of the front and back position of the screen, the hand-rotating rod 25 is rotated. The hand-rotating rod 25 is threadedly connected to the slider 23. The rotation of the hand-rotating rod 25 drives the slider 23 to move back and forth inside the fixed frame 21. The front and back position of the connecting block 24 on the base 1 can be adjusted, so as to realize the convenient adjustment of the center of gravity of the rotating arm 27 on the base 1, improve the support stability of the base 1 for the device, and ensure the practicality of the device.
