[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a liquid crystal display lifting bracket. When the display needs to be raised, the lifting platform is pulled directly. When the lifting platform rises, it will drive the locking tongue to rise. At this time, the rack moves downward relative to the locking tongue, and the teeth behind the rack will press against the inclined surface in front of the locking tongue, causing the locking tongue to move away from the rack. As the locking tongue moves away from the rack, the spring is compressed. After the teeth of the rack that press against the locking tongue pass by the locking tongue, the spring rebounds and pushes the locking tongue into the tooth gap of the rack.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 As shown, this utility model provides a liquid crystal display lifting stand, including a base 1, a lifting module 2 slidably connected inside the base 1, and a tilting module 3 fixedly connected above the lifting module 2. When it is necessary to raise and adjust the height of the display, the lifting module 2 can be raised directly. When it is necessary to lower, the adjustment switch 22 can be pressed to lower the lifting module 2. The tilt angle of the display can be adjusted by pressing the adjustment switch 36.

[0023] like Figure 2 As shown, this utility model provides a technical solution: a plurality of threaded holes are provided at the bottom of the tilting module 3, and a plurality of threaded holes are provided at the front side of the lifting module 2. Bolts are threaded into the threaded holes of both the lifting module 2 and the tilting module 3, and a tripod 4 is fixedly connected to them by the bolts. The tripod 4 enhances the stability of the tilting module 3 and the lifting module 2, and prevents the tilting module 3 from detaching from the lifting module 2 due to excessive weight of the display or other factors.

[0024] like Figure 3 As shown, this utility model provides a technical solution: the base 1 includes a support seat 12, a support plate 11 is fixedly connected to the left side of the support seat 12, a rack 13 is fixedly connected inside the support seat 12, and the support plate 11 prevents dust or other debris from falling into the support seat 12 and affecting the sliding of the lifting module 2.

[0025] like Figure 4As shown, this utility model provides a technical solution: a lifting platform 21 is slidably connected inside the support base 12, a rack 13 is inside the lifting platform 21 and slidably connected thereto, a cover plate 29 is fixedly connected to the left side of the lifting platform 21, a locking tongue 26 is engaged behind the rack 13, the left and right sides of the locking tongue 26 are rotatably connected to the cover plate 29 and the lifting platform 21 respectively, a spring 27 is fixedly connected to the rear of the locking tongue 26, a fixing block 28 is fixedly connected to the rear of the spring 27, the fixing block 28 is fixedly connected to the lifting platform 21, a connecting rod 25 is rotatably connected to the top of the locking tongue 26 via a pin, and eccentric rods 24 are rotatably connected to the left and right sides of the other end of the connecting rod 25. Two eccentric rods 24 are mirror images of each other on both sides of the connecting rod 25 and are rotatably connected to the cover plate 29 and the lifting platform 21, respectively. An adjustment switch 22 is slidably connected above the lifting platform 21. A fixing block 23 is fixedly connected above the eccentric rods 24 on the lifting platform 21. The fixing block 23 is slidably connected to the adjustment switch 22. The lower end of the adjustment switch 22 has an oblong hole and is slidably connected to the end of the eccentric rod 24 away from the connecting rod 25. When the display needs to rise, the lifting platform 21 is pulled directly. When the lifting platform 21 rises, it will cause the latch 26 to rise. At this time, the rack 13 moves downward relative to the latch 26, and the teeth at the rear of the rack 13 will press against the front of the latch 26. The inclined plane causes the latch 26 to move away from the rack 13. As the latch 26 moves away from the rack 13, the spring 27 is compressed. After the rack 13's teeth press past the latch 26, the spring 27 rebounds, pushing the latch 26 into the tooth gap of the rack 13. Then, the next tooth of the rack 13 continues to press the latch 26, compressing the spring 27, and repeating this action. Once the appropriate height is reached, the lifting platform 21 is stopped. The lifting platform 21 will tend to descend due to gravity, but the spring 27 will engage the front end of the latch 26 in the tooth gap of the rack 13, causing the latch 26 to rotate upwards and lock, thus preventing the lifting platform 21 from descending due to gravity. When it needs to be lowered... When the height of the lifting platform 21 is reached, press the adjustment switch 22. The adjustment switch 22 will push the eccentric rod 24 to rotate. When the eccentric rod 24 rotates, it will pull the rear end of the locking tongue 26 to rotate through the connecting rod 25. At this time, the front end of the locking tongue 26 will move away from the tooth gap of the rack 13 and compress the spring 27. The lifting platform 21 can then move up and down freely. After descending to the desired position, release the adjustment switch 22. The spring 27 will rebound and lock the front end of the locking tongue 26 back into the rack 13. The fixing block 28 fixes one end of the spring 27 so that the spring 27 can be compressed when the locking tongue 26 moves away from the rack 13. The fixing block 23 provides a guiding function for the adjustment switch 22.

[0026] like Figure 5As shown, this utility model provides a technical solution: the tilting module 3 includes a connecting platform 31, an extension rod 310 fixedly connected to the rear of the connecting platform 31, a cover plate 39 rotatably connected to the right side of the extension rod 310, a gear 32 fixedly connected to the left side of the extension rod 310, a fixing seat 33 fixedly connected to the left side of the gear 32, the fixing seat 33 being fixedly connected to the cover plate 39, a locking tongue 34 rotatably connected to the fixing seat 33 behind the gear 32, the front end of the locking tongue 34 engaging the gear 32, a support rod 38 rotatably connected to the left side of the locking tongue 34, the support rod 38 being fixedly connected to the fixing seat 33, a spring 35 fixedly connected to the top of the locking tongue 34, the other end of the spring 35 being fixedly connected to the fixing seat 33, a fixing block 37 fixedly connected to the fixing seat 33 behind the support rod 38 and having a through hole below it, an adjusting switch 36 slidably connected inside the fixing block 37, an oblong hole above the adjusting switch 36 and slidably connected to the locking tongue 34. The lower end of the adjustment switch 2 36 passes through the fixed base 33 and is slidably connected to it. The fixed base 33 is fixedly connected to the upper surface of the lifting platform 21. When it is necessary to adjust the angle of the monitor, the connecting platform 31 is fixed behind the monitor. Pressing the adjustment switch 2 36 pushes the locking tongue 2 34 to rotate, compressing the spring 2 35. At this time, the front end of the locking tongue 2 34 moves away from the gear 32, and the connecting platform 31 can rotate freely. When the desired angle is adjusted, the adjustment switch 2 36 is released, and the spring 2 35 rebounds and pushes the locking tongue 2 34, locking the front end of the locking tongue 2 34 into the tooth gap of the gear 32, so that the gear 32 cannot rotate. The connecting platform 31 is fixed through the gear 32, and the connecting platform 31 then fixes the monitor. The fixing block 2 28 and the fixed base 33 support the rotation of the locking tongue 2 34. The waist-shaped hole above the adjustment switch 2 36 prevents the locking tongue 2 34 from jamming with the adjustment switch 2 36 when rotating. The fixing block 3 37 increases the stability of the adjustment switch 2 36 when sliding and adds a guiding function.

[0027] The working principle of this LCD monitor lifting bracket will be explained in detail below.

[0028] like Figure 1-5As shown, when the monitor needs to be raised, the lifting platform 21 is pulled directly. As the lifting platform 21 rises, it causes the locking tongue 26 to rise as well. At this time, the rack 13 moves downwards relative to the locking tongue 26, and the teeth at the rear of the rack 13 press against the inclined surface in front of the locking tongue 26, causing the locking tongue 26 to move away from the rack 13. Simultaneously, the spring 27 is compressed as the locking tongue 26 moves away from the rack 13. After the teeth of the rack 13 that press against the locking tongue 26 pass slightly past the locking tongue 26, the spring 27 rebounds, pushing the locking tongue 26 into the tooth gap of the rack 13. Then, the next tooth of the rack 13 continues to press against the locking tongue 26, compressing the spring 27. Repeat the above actions. Once the appropriate height is reached, stop pulling the lifting platform 21. The lifting platform 21 will tend to descend due to gravity, but spring 27 will engage the front end of the locking tongue 26 in the tooth clearance of the rack 13, causing the locking tongue 26 to rotate upwards and lock, thus preventing the lifting platform 21 from descending due to gravity. When it is necessary to lower the height of the lifting platform 21, press the adjustment switch 22. The adjustment switch 22 will push the eccentric rod 24 to rotate. When the eccentric rod 24 rotates, it will pull the rear end of the locking tongue 26 to rotate through the connecting rod 25. At this time, the front end of the locking tongue 26 will move away from the tooth clearance of the rack 13 and compress the spring 27. 27. At this point, the lifting platform 21 can move freely up and down. After descending to the desired position, release the adjustment switch 22. The spring 27 rebounds and again engages the front end of the locking tongue 26 with the rack 13. The fixing block 28 fixes one end of the spring 27, allowing the locking tongue 26 to move away from the rack 13 and compress the spring 27. The fixing block 23 provides a guide for the adjustment switch 22. When it is necessary to adjust the angle of the monitor, the connecting platform 31 is fixed behind the monitor. Press the adjustment switch 36. The adjustment switch 36 pushes the locking tongue 34 to rotate, compressing the spring 35. At this time, the front end of the locking tongue 34 moves away from the rack 13. Once gear 32 is disengaged, connecting platform 31 can rotate freely. After adjusting to the desired angle, release adjustment switch 2 36. Spring 2 35 rebounds and pushes locking tongue 2 34, locking the front end of locking tongue 2 34 into the tooth gap of gear 32, preventing gear 32 from rotating. Connecting platform 31 is fixed through gear 32, and connecting platform 31 then fixes the display. Fixing block 2 28 and fixing base 33 support the rotation of locking tongue 2 34. The oblong hole above adjustment switch 2 36 prevents locking tongue 2 34 from jamming with adjustment switch 2 36 when rotating. Fixing block 3 37 increases the stability of adjustment switch 2 36 when sliding and provides guidance.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
