Description

Technical Field

[0001] This invention belongs to the field of monitor lifting brackets and relates to a monitor lifting bracket. Background Technology

[0002] With the widespread adoption of electronic office systems, monitors have become core devices for daily office work and gaming. For monitors that heavily utilize metal backplates, the heat dissipation vents on the back panel expel a significant amount of heat during prolonged high-load operation. Relying solely on the monitor's own cooling system has limited efficiency, leading to internal heat buildup, screen stuttering, and accelerated component aging. Existing monitor stands mostly only provide support, height adjustment, and rotation, lacking an integrated auxiliary cooling structure to match the monitor's heat dissipation. Many external cooling fans are open-type, unable to precisely align with the ventilation vents, resulting in significant airflow leakage and poor cooling performance. Furthermore, in low-temperature winter environments, users' hands are easily chilled when operating the keyboard and mouse, affecting operational comfort and work efficiency. Existing hand warmers require additional power and occupy desk space, making them unsuitable for use with monitor stands.

[0003] Therefore, the present invention provides a monitor lift stand to solve the above problems. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention discloses a monitor lifting bracket. The technical solution adopted is as follows: it includes a base, and a lifting frame is fixedly installed in the middle of the rear edge of the base. The lifting frame includes a hollow column with an upper opening. The left and right inner side walls of the hollow column are evenly toothed from top to bottom. A hollow lifting rod that can slide and extend vertically is fitted inside the hollow column. The bottom left and right side walls of the hollow lifting rod are symmetrically provided with through grooves. A display screen mounting plate is installed at the upper end of the front side wall of the hollow lifting rod. A locking mechanism is set in the upper part of the lifting rod in the left and right through grooves. The locking mechanism realizes the vertical movement adjustment of the hollow lifting rod relative to the hollow column by locking the left and right teeth. An air pump is installed at the bottom of the hollow column. The upper air inlet of the air pump is connected to an air inlet hose. The air inlet hose passes through one end of the top right front corner of the hollow lifting rod and communicates with the rear end of the magnetic suction hood. The front exhaust pipe of the air pump passes through one end of the front side wall of the hollow column and is sealed with a rotatable exhaust component.

[0005] As a preferred embodiment of the present invention, the lower part of the base is uniformly provided with anti-slip texture.

[0006] In a preferred embodiment of the present invention, the locking mechanism includes fixed posts fixed to the inner walls of the front and rear sides of the hollow lifting rod. The upper ends of the left and right ratchet teeth are rotatably fitted onto the front and rear sides of the fixed posts, respectively. A slot is formed in the upper middle part of the left and right ratchet teeth. Limiting posts are fixedly installed on the inner walls of the front and rear sides of the posts directly opposite the slots of the left and right ratchet teeth. The fixed posts on the front and rear sides of the upper end of the ratchet teeth are respectively hinged to the two ends of the U-shaped pull rod built into the hollow lifting rod. The upper end of the U-shaped pull rod is fixedly connected to a pin. The part of the pin located inside the hollow lifting rod is fitted with a spring. By adopting the locking mechanism, when the pin is pulled upward, the ratchet teeth fitted on the fixed posts are pulled by the U-shaped pull rod. Due to the action of the left and right limiting posts, the lower ends of the left and right ratchet teeth retract inward during the upward movement, thereby disengaging from the corresponding teeth on the left and right sides. This facilitates the up and down movement of the lifting rod and the adjustment of the height of the display screen mounted on the display screen mounting plate. After the pin is released, the left and right ratchet teeth are successfully inserted into the corresponding teeth on the left and right sides under the action of the spring, realizing the rapid fixation of the height.

[0007] As a preferred embodiment of the present invention, the lower ends of the left and right ratchet teeth respectively engage with the corresponding left and right teeth.

[0008] In a preferred embodiment of the present invention, the upper end of the pin extends through the top of the hollow lifting rod.

[0009] As a preferred embodiment of the present invention, a silicone sealing ring is provided on the outer edge of the front end of the magnetic suction hood, and a permanent magnet is embedded in the front end of the magnetic suction hood; by using the silicone sealing ring, it is easy to seal and adsorb the magnetic suction hood to the outer edge of the exhaust hole on the back side of the display screen under the action of the permanent magnet.

[0010] In a preferred embodiment of the present invention, the exhaust assembly includes a rotary sealing joint that is rotatably and sealingly connected to the front exhaust pipe of the air pump. An exhaust hood is rotatably and sealingly connected to the upper exhaust end of the rotary sealing joint. A magnetic block is embedded in the front side wall of the cavity column directly opposite the rear of the exhaust hood, and the magnetic block is magnetically attracted to the exhaust hood. The two ends of the rotary sealing joint are respectively connected with a damping structure, so that the exhaust hood can rotate around the front exhaust pipe of the air pump through the rotary sealing joint. At the same time, the exhaust hood can rotate 360 ​​degrees around the other end of the rotary sealing joint, thereby facilitating flexible adjustment of the position of the exhaust hood and the direction of exhaust, and improving its ease of use.

[0011] As a preferred embodiment of the present invention, the exhaust hood has exhaust holes evenly distributed on its front sidewall.

[0012] The beneficial effects of this invention are:

[0013] The height adjustment uses a ratchet and tooth-engaging locking mechanism. Pulling the pin will quickly unlock the mechanism, and releasing it will automatically lock it in place. It is stable under load and will not slip. The adjustment operation is simple.

[0014] The magnetic exhaust cover is fixed by a permanent magnet and a silicone sealing ring to achieve a tight fit. It is precisely aligned with the heat dissipation holes of the monitor, and the air pump creates negative pressure exhaust, which significantly improves the heat dissipation efficiency.

[0015] The exhaust system uses a damped rotating sealed joint that can be freely rotated to adjust the airflow direction: in winter, it blows forward and downward at an angle to heat the keyboard operating area; in summer, it exhausts backward or upward to avoid hot air blowing directly on the human body and to achieve waste heat reuse.

Detailed Implementation

[0024] Example 1

[0025] like Figures 1 to 7As shown, the technical solution of the monitor lifting bracket of the present invention includes a base 1. The lower part of the base 1 is uniformly textured with anti-slip texture. A lifting frame 2 is fixedly installed in the middle of the rear edge of the base 1. The lifting frame 2 includes a hollow column 21 with an upper opening. The left and right inner walls of the hollow column 21 are uniformly provided with teeth 211 from top to bottom. A hollow lifting rod 22 that can slide and extend vertically is slidably engaged in the hollow column 21. The bottom left and right side walls of the hollow lifting rod 22 are symmetrically provided with through grooves 221. A display screen mounting plate 23 is installed on the upper end of the front side wall of the hollow lifting rod 22. Mounting holes are provided at the four corners of the display screen mounting plate 23. A locking mechanism 3 is provided in the upper part of the lifting rod in the left and right through grooves 221. The locking mechanism 3 includes a fixing post 31 fixed to the front and rear inner walls of the hollow lifting rod 22. The front and rear of the fixing post 31 are respectively rotatably fitted with the upper ends of the left and right ratchet teeth 32. The lower ends of the left and right ratchet teeth 32 respectively engage with the corresponding teeth 211 on the left and right. A slot 321 is formed in the upper middle part of the left and right ratchet teeth 32. Limiting posts 33 are fixedly installed on the front and rear inner walls of the column directly opposite the slots 321. The fixed posts on the front and rear sides of the upper end of the ratchet teeth 32 are hinged to the two ends of the U-shaped pull rod 34 built into the hollow lifting rod 22. A pin 35 is fixedly connected to the upper end of the U-shaped pull rod 34. The upper end of the pin 35 movably passes through the top of the hollow lifting rod 22. A spring 36 is fitted onto the portion of the pin 35 inside the hollow lifting rod 22. The locking mechanism 3 achieves the up-and-down movement adjustment of the hollow lifting rod 22 relative to the hollow column 21 by locking the left and right teeth 211. An air pump 4 is installed at the bottom inside the hollow column 21, and air is introduced into the upper end of the air pump 4. An air inlet hose 41 is connected to the hollow lifting rod 22. The air inlet hose 41 passes through one end of the top right front corner and connects to the rear end of the magnetic suction hood 5. A silicone sealing ring 51 is provided on the outer edge of the front end of the magnetic suction hood 5. A permanent magnet 52 is embedded in the front end of the magnetic suction hood 5. The exhaust pipe of the front end of the air pump 4 passes through one end of the front side wall of the hollow column 21 and is sealed with a rotatable exhaust assembly 6. The exhaust assembly 6 includes a rotating sealing joint 61 that is rotatably and sealingly connected to the exhaust pipe of the front end of the air pump 4. The upper exhaust end of the rotating sealing joint 61 is rotatably and sealingly connected to an exhaust hood 62. Exhaust holes 621 are evenly opened on the front side wall of the exhaust hood 62. A magnetic block 63 is embedded in the front side wall of the hollow column 21 directly opposite the rear of the exhaust hood 62. The magnetic block 63 is magnetically attracted to the exhaust hood 62.

[0026] Working principle of the invention:

[0027] Before use, fix the monitor to the display mounting plate 23 at the front end of the hollow lifting rod 22 with fasteners, and attach the magnetic exhaust cover 5 to the outer edge of the heat dissipation hole on the back of the monitor with the help of the internal permanent magnet 52. The silicone sealing ring 51 is tightly attached to the monitor shell under the magnetic attraction to form a sealed exhaust channel to prevent air leakage and ensure heat dissipation efficiency.

[0028] When adjusting the height, the user pulls the pin 35 at the top of the hollow lifting rod 22 upwards. The pin 35 drives the U-shaped pull rod 34 upwards, which in turn pulls the left and right ratchet teeth 32 to rotate around the fixed column 31. Under the limiting constraint of the limiting column 33, the lower end of the ratchet teeth 32 retracts inwards and disengages from the teeth 211 on the inner side of the hollow column 21. At this time, the hollow lifting rod 22 can slide freely up and down along the hollow column 21 to adjust the display to a suitable height. After the adjustment is completed, the pin 35 is released, and the spring 36 pushes the pin 35 and the U-shaped pull rod 34 to reset. The ratchet teeth 32 open outwards again and engage with the corresponding teeth 211, achieving height self-locking and preventing slippage or shaking.

[0029] After the air pump 4 is started, it forms a negative pressure air duct with the magnetic suction hood 5 through the air intake hose 41, forcibly extracting the hot air generated inside the monitor. The hot air is sent to the exhaust assembly 6 through the exhaust pipe at the front end of the air pump 4, and discharged through the rotating sealing joint 61 and the exhaust hood 62. The rotating sealing joint 61 adopts a damped sealing structure, which can drive the exhaust hood 62 to rotate freely and maintain its position: in winter, the exhaust port 621 side of the exhaust hood 62 is rotated to the front and lower, so that the hot air is blown towards the keyboard and hand area, using the waste heat of the monitor for heating; in summer, the exhaust port 621 side of the exhaust hood 62 is rotated to the rear or top, so that the hot air is discharged away from the human body. The exhaust hood 62 can be positioned with the assistance of the magnetic block 63, further improving the stability of use. The entire device simultaneously achieves height adjustment, sealed heat dissipation and waste heat utilization, and is stable in operation and easy to use.
