[0014] When the mounting plate is in the closed state, the second support member is in contact with the base plate, and the locking pin assembly is locked in the first locking position. When the locking pin assembly is disengaged from the first locking position, the first support member is rotated so that the second support member is perpendicular to the base plate, and the locking pin assembly is locked in the second locking position. At this time, the mounting plate is in the stretched state.

[0015] In some embodiments, the mounting base includes a base body and an end cap detachably connected to the base body, the base body having a shaft hole for the rotating shaft to extend into and a pin hole for engaging with the locking pin assembly.

[0016] In some embodiments, the locking pin assembly includes a locking pin, a first elastic element fitted onto the locking pin, and a pull cord connected to the locking pin. The locking pin passes through the pin hole and extends at both ends to the outside of the mounting base. The first elastic element causes the locking pin to tend toward the rotation axis.

[0017] In some embodiments, the locking pin includes a pull ring portion, a body portion, a limiting portion, and a locking portion arranged sequentially from the slider toward the first support member. The first elastic member abuts between the limiting portion and the mounting base.

[0018] In some embodiments, the rotating shaft includes a rotating shaft body, a locking disc, and a fixing part arranged sequentially, the fixing part being fixedly connected to the first support member, and the first locking position and the second locking position being arranged on the outer periphery of the locking disc.

[0019] In some embodiments, the mounting plate is provided with a magnetic element, and when the mounting plate is in a closed state, the mounting plate is magnetically attracted to the first support member by the magnetic element.

[0020] In some embodiments, the second support member is provided with a metal inner sleeve, the metal inner sleeve having a plurality of circular holes in its circumference to accommodate a plurality of metal steel balls, the plurality of metal steel balls being in rolling engagement with the first support member, and the second support member having fixed end caps at both ends of the metal inner sleeve.

[0021] In some embodiments, the gravity balancing assembly includes two gravity balancing modules arranged vertically at intervals and a transmission chain supported by the two gravity balancing modules, and the slider is fixedly connected to the transmission chain via a connecting plate.

[0022] In some embodiments, the gravity balancing module includes a flange rotatably mounted on a positioning post on the base plate, a gear disk coaxially arranged on the outer periphery of the flange, a scale disk coaxially arranged on the inner periphery of the flange, a locking nut threadedly connected to the positioning post, a spring plate disposed between the locking nut and the scale disk, and a plurality of needle roller assemblies disposed between the flange and the gear disk. A plurality of accommodating spaces for accommodating the plurality of needle roller assemblies are provided between the flange and the gear disk. The accommodating spaces gradually narrow along the descending direction of the slider. Each needle roller assembly includes a needle roller near the narrowing end of the accommodating space and a second elastic element abutting between the needle roller and the flange.

[0023] The locking nut is provided with a pointer that cooperates with the dial, a first friction plate is provided between the flange and the base plate, and a second friction plate is provided between the dial and the flange.

[0024] In some embodiments, a gear disk cover and a decorative housing are also included. The gear disk cover is annular and fixed to the flange.

[0049] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0050] like Figure 1 The diagram shown is a structural schematic of the present invention, which provides a wall mount that can be adjusted up, down, left, and right in height, including a base plate 1, an up-and-down operating mechanism, a first support member 3, a gravity balancing mechanism, a second support member 5, a mounting plate 6, and a locking mechanism 7.

[0051] The base plate 1 is fixed to the mounting surface where the monitor 8 needs to be installed, such as a wall.

[0052] The vertical running mechanism is mounted on the base plate 1 and includes two vertical running components 2 arranged symmetrically on the left and right. Specifically, the vertical running component 2 includes a guide rail 2-1 arranged in the vertical direction and a slider 2-2 slidably connected to the guide rail 2-1.

[0053] The first support member 3 is located between the two vertical moving components 2 and moves vertically under the action of the two sliders 2-2. In this example, the first support member 3 adopts a metal square tube structure, and a rotating shaft 3-1 is provided at each end of the first support member 3.

[0054] like Figure 8 and Figure 9 As shown, a gravity balancing mechanism is mounted on a base plate 1 and connected to two sliders 2-2 to maintain the balance of the first support member 3. It includes two gravity balancing components 4 symmetrically arranged on both sides of the length of the first support member 3. Each gravity balancing component 4 includes two gravity balancing modules spaced vertically apart and a transmission chain 4-5 supported by the two gravity balancing modules. The sliders 2-2 are fixedly connected to the transmission chain 4-5 via a connecting plate 9. The connecting plate 9 is fixed to the sliders 2-2 with screws, and the connecting plate 9 can be welded to the transmission chain 4-5.

[0055] The gravity balance module includes a flange 4-1 rotatably mounted on a positioning post 1-1 on the base plate 1, a gear disk 4-2 coaxially arranged on the outer periphery of the flange 4-1, a scale disk 4-4 coaxially arranged on the inner periphery of the flange 4-1, a locking nut 4-6 threadedly connected to the positioning post 1-1, a spring piece 4-7 disposed between the locking nut 4-6 and the scale disk 4-4, and multiple needle roller assemblies 4-3 disposed between the flange 4-1 and the gear disk 4-2. Multiple accommodating spaces for accommodating multiple needle roller assemblies 4-3 are provided between the flange 4-1 and the gear disk 4-2. The accommodating spaces gradually narrow along the descending direction of the slider 2-2. The needle roller assembly 4-3 includes a needle roller 4-3a near the narrowing end of the accommodating space and a second elastic element 4-3b abutting between the needle roller 4-3a and the flange 4-1. A pointer that mates with the dial 4-4 is provided on the locking nut 4-6. A first friction plate 4-8 is provided between the flange 4-1 and the base plate 1, and a second friction plate 4-9 is provided between the dial 4-4 and the farad 4-1. Preferably, the second elastic element 4-3b is a spring.

[0056] like Figure 8As shown, when the display 8 descends, the first support member 5 drives the slider 2-2 to move downward along the guide rail 2-1, the transmission chain 4-5 drives the gear disk 4-2 to move clockwise, and the needle roller 4-3a rubs against the inner wall of the accommodating space and rotates clockwise under the action of the second elastic member 4-3b. The needle roller 4-3a moves along the direction with the smallest gap in the accommodating space, thereby locking it, so that the gear disk 4-2 drives the flange 4-1 to move together. The flange 4-1 can be set with a certain torque to rotate, so that the gear disk 4-2 has a certain torque when rotating clockwise to balance the weight of the display 8, ensuring that the display 8 will not fall and can stop at any position. When the monitor 8 rises, the first support 3 drives the slider 2-1 to move upwards, the transmission chain 4-5 drives the gear disk 4-2 to move counterclockwise, and the needle roller 4-3a moves along the direction with the largest gap in the accommodating space. At this time, there is a gap between the gear disk 4-2, the flange 4-1, and the needle roller 4-3a. The gear disk 4-2 moves independently without any torque applied, causing the monitor 8 to rise. When it stops, due to gravity, the gear disk 4-2 tends to rotate clockwise downwards, giving the gear disk 4-2 a certain torque to balance the weight of the monitor 8 and ensure that the monitor 8 will not fall. It can stop at any position.

[0057] To improve the compactness and aesthetics of the structure, a gear disc cover plate 4-11 and a decorative outer shell 4-12 are also provided. The gear disc cover plate 4-11 is annular and fixed to the flange 4-1 by multiple screws so that the needle roller assembly 4-3 is held between the gear disc 4-2 and the flange 4-1. The decorative outer shell 4-12 covers the two gravity balance modules and the transmission chain 4-5 and is fixed to the base plate 1. The decorative outer shell 4-12 and the gear disc cover plate 4-11 are respectively provided with torque adjustment clearance grooves. By rotating the locking nut 4-6, the distance between the locking nut 4-6 and the dial 4-4 is adjusted, causing the spring 4-7 to deform, thereby adjusting the torque of the flange 4-1.

[0058] To improve the stability of the structure, a locking screw 4-10 is also provided, which is threaded to the positioning post 1-1 and abuts against the upper end of the locking nut 4-6 to limit the locking nut 4-6 on the positioning post 1-1.

[0059] like Figure 4As shown, the second support member 5 has one end slidably mounted on the first support member 3 and moves along the length of the first support member 3. To facilitate the sliding engagement between the second support member 5 and the first support member 3, a metal inner sleeve 5-1 is provided inside the second support member 5. Multiple circular holes are provided around the circumference of the metal inner sleeve 5-1 to accommodate multiple metal steel balls 5-2. The multiple metal steel balls 5-2 roll in engagement with the first support member 3. Fixed end caps 5-3 are respectively provided at both ends of the metal inner sleeve 5-1 on the second support member 5. This structure ensures smooth left-right movement of the second support member 5 on the first support member 3.

[0060] Mounting plate 6, which is rotatably connected to the other end of the second support member 5, is used to mount display 8. Specifically, mounting plate 6 and second support member 5 are rotatably connected via a pivot.

[0061] To facilitate the positioning of the monitor 8 and the mounting plate 6, multiple U-shaped grooves 6-1 are provided on the upper end of the mounting plate 6. At the same time, at least two U-shaped rollers 8-1 that cooperate with the U-shaped grooves 6-1 are fixed on the monitor 8. By cooperating with the U-shaped rollers 8-1 and the U-shaped grooves 6-1, the monitor 8 can be quickly positioned on the mounting plate 6, and then the lower part of the monitor 8 can be fixed on the mounting plate 6.

[0062] like Figures 5 to 7 As shown, the locking mechanism 7 is mounted on the slider 2-2 and is used to lock the rotating shaft 3-1 on one side. It includes a mounting base and a locking pin assembly that cooperates with the rotating shaft 3-1. The rotating shaft 3-1 is rotatably engaged with the mounting base. The rotating shaft 3-1 is provided with a first locking position 3-1bl and a second locking position 3-1b2 that cooperate with the locking pin assembly. When the locking pin assembly is located at the first locking position 3-1bl and the second locking position 3-1b2 respectively, the mounting plate 6 is in the closed state and the stretched state respectively.

[0063] Specifically, the mounting base includes a base body 7-1 and an end cap 7-2 detachably connected to the base body 7-1. The base body 7-1 is provided with a shaft hole 7-1a into which the rotating shaft 3-1 extends and a pin hole 7-1b that cooperates with the locking pin assembly. The rotating shaft 3-1 is rotatably disposed in the shaft hole 7-1a, and the locking pin assembly can extend through the pin hole 7-1b to the first locking position 3-1bl or the second locking position 3-1b2.

[0064] The locking pin assembly includes a locking pin 7-3, a first elastic element 7-4 sleeved on the locking pin 7-3, and a pull cord 7-5 connecting the locking pin 7-3. The locking pin 7-3 passes through a pin hole 7-1b and extends to the outside of the mounting base at both ends. The first elastic element 7-4 causes the locking pin 7-3 to tend to move towards the rotation shaft 3-1, so that the locking pin 7-3 is stably held in the first locking position 3-1b1 and the second locking position 3-1b2. Preferably, the first elastic element 7-4 is a spring.

[0065] The locking pin 7-3 includes a pull ring portion 7-3a, a body portion 7-3b, a limiting portion 7-3c, and a locking portion 7-3d arranged sequentially from the slider 2-2 toward the first support member 3. The outer diameter of the limiting portion 7-3c is larger than that of the body portion 7-3b and the locking portion 7-3d. The first elastic member 7-4 abuts between the limiting portion 7-3c and the mounting base. The first locking position 3-1bl and the second locking position 3-1b2 are limiting ports that cooperate with the locking portion 7-3d.

[0066] The rotating shaft 3-1 includes a rotating shaft body 3-1a, a locking disc 3-1b, and a fixing part 3-1c arranged sequentially. The fixing part 3-1c is fixedly connected to the first support member 3 by screws. The first locking position 3-1b1 and the second locking position 3-1b2 are arranged on the outer periphery of the locking disc 3-1b, and the included angle between them is ninety degrees.

[0067] To improve the stability of the structure, a magnetic component 3-2 is provided on the mounting plate. When the mounting plate 6 is in the closed state, the second support component 5 is attached to the base plate 1, and the mounting plate 6 is attracted to the first support component 3 by the magnetic component 3-2, thus ensuring the stability of the closed structure.

[0068] The installation process for the monitor is as follows:

[0069] When it is necessary to install the monitor 8, pull out the locking pin 7-3 by pulling the cord 7-5. The locking pin 7-3 disengages from the first locking position 3-1bl. Rotate the first support member 3 so that the second support member 5 is perpendicular to the base plate 1. At this time, release the locking pin 7-3. Under the action of the first elastic member 7-4, the locking pin 7-3 is held in the second locking position 3-1b2, so that the mounting plate 6 is in a stretched state (e.g., Figure 2 (As shown), then the U-shaped roller 8-1 at the rear of the monitor 8 is installed in the U-shaped groove 6-1 on the mounting plate 6 to position the monitor 8. Finally, the lower part of the monitor 8 is fixed to the mounting plate 6 with screws.

[0070] After the monitor 8 is installed, pull out the locking pin 7-3 using the pull cord 7-5. The locking pin 7-3 disengages from the second locking position 3-1b2. Rotate the first support member 3 so that the second support member 5 fits against the base plate 1. The mounting plate 6 rotates accordingly and becomes parallel to the base plate 1. At this time, release the locking pin 7-3. The locking pin 7-3 remains in the first locking position 3-1b1 under the action of the first elastic member 7-4, keeping the mounting plate 6 in a closed state (e.g., Figure 3 As shown), this ensures that the first support member 3 is stably held on the slider 2-2.

[0071] The process of adjusting the left and right position of the monitor is as follows:

[0072] When it is necessary to adjust the left and right position of the display 8, pull the display 8, and the second support 5 will move along the length of the first support 3 to complete the adjustment of the left and right position.

[0073] The process of adjusting the monitor's height is as follows:

[0074] When the monitor 8 descends, the first support member 3 drives the slider 2-2 to move downward along the guide rail 2-1. The transmission chain 4-5 drives the gear disk 4-2 on one side to move clockwise (the gear disk 4-2 on the other side rotates counterclockwise). The needle roller 4-3a rubs against the inner wall of the accommodating space under the action of the second elastic member 4-3b and rotates clockwise. The needle roller 4-3a moves along the direction with the smallest gap in the accommodating space, thus locking it, so that the gear disk 4-2 drives the flange 4-1 to move together. The flange 4-1 rotates after being set with a certain torque by the locking nut 4-6, so that the gear disk 4-2 has a certain torque when rotating clockwise to balance the weight of the monitor 8, ensuring that the monitor 8 will not fall and can stop at any position. When it is necessary to adjust the torque of flange 4-1, the locking nut 4-6 is rotated to make the pointer point to the appropriate position. The distance between the locking nut 4-6 and the dial 4-4 is adjusted to deform the spring 4-7, thereby giving flange 4-1 the required torque.

[0075] When the monitor 8 rises, the first support 3 drives the slider 2-2 to move upwards. The transmission chain 4-5 drives the gear disk 4-2 on one side to move counterclockwise (the gear disk 4-2 on the other side rotates clockwise). The needle roller 4-3a moves along the direction with the largest gap in the accommodating space. At this time, there is a gap between the gear disk 4-2, the flange 4-1, and the needle roller 4-3a. The gear disk 4-2 moves independently without torque, causing the monitor 8 to rise. When it stops, due to gravity, the gear disk 4-2 tends to rotate downwards clockwise (the other side rotates counterclockwise), giving the gear disk 4-2 a certain torque to balance the weight of the monitor 8 and prevent it from falling. It can stop at any position.

[0076] In summary, this wall mount allows for adjustment of the monitor in both left and right and height directions, making it easy to operate and highly stable.
