[0049] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those in routine experiments.

[0050] like Figure 1 As shown, it is a structural schematic diagram of the present invention, which provides a wall mount with adjustable up, down, left and right heights, including a base plate 1, an up and down running 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 on a mounting surface where the display 8 needs to be mounted, such as a wall.

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

[0053] The first support member 3 is arranged between the two upper and lower running components 2 and moves in the vertical direction driven by 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 both ends of the first support member 3.

[0054] like Figure 8 and Figure 9 As shown, the gravity balancing mechanism is mounted on the base plate 1 and connected to the two sliders 2-2. It is used to balance the first support member 3 and includes two gravity balancing assemblies 4 symmetrically arranged on either side of the length of the first support member 3. The gravity balancing assembly 4 includes two gravity balancing modules spaced apart from each other and a transmission chain 4-5 supported by the two gravity balancing modules. The slider 2-2 is fixedly connected to the transmission chain 4-5 via a connecting plate 9. The connecting plate 9 and the slider 2-2 are fixed by screws, and the connecting plate 9 and the transmission chain 4-5 can be fixed by welding.

[0055] The gravity balancing module includes a flange 4-1 rotatably set on the positioning column 1-1 of the base plate 1, a gear plate 4-2 coaxially arranged on the outer periphery of the flange 4-1, a scale plate 4-4 coaxially arranged on the inner periphery of the flange 4-1, a locking nut 4-6 threadedly connected to the positioning column 1-1, a spring 4-7 arranged between the locking nut 4-6 and the scale plate 4-4, and a plurality of needle roller assemblies 4-3 arranged between the flange 4-1 and the gear plate 4-2. A plurality of accommodating spaces for accommodating the plurality of needle roller assemblies 4-3 are provided between the flange 4-1 and the gear plate 4-2. The accommodating spaces are gradually contracted along the descending direction of the slider 2-2. The needle roller assembly 4-3 includes a needle roller 4-3a near the contraction end of the accommodating space and a second elastic member 4-3b abutting between the needle roller 4-3a and the flange 4-1. A pointer that matches the scale plate 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 scale plate 4-4 and the Ferrari disc 4-1. Preferably, the second elastic member 4-3b is a spring.

[0056] like Figure 8 As 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, and the transmission chain 4-5 drives the gear plate 4-2 to move in the clockwise direction. 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 in the direction of the smaller gap in the accommodating space and is stuck, so that the gear plate 4-2 drives the flange plate 4-1 to move together. The flange plate 4-1 can be set to a certain torque and then rotated, so that the gear plate 4-2 has a certain torque when rotating clockwise to balance the gravity of the display 8, ensuring that the display 8 will not fall and can stop at any position. When the display 8 is raised, the first support member 3 drives the slider 2-1 upward, the transmission chain 4-5 drives the gear plate 4-2 in a counterclockwise direction, and the needle roller 4-3a moves along the direction of the largest gap in the accommodating space. At this time, there is a gap between the gear plate 4-2, the flange 4-1, and the needle roller 4-3a. The gear plate 4-2 moves independently without applying torque, causing the display 8 to rise. When stopping, due to the influence of gravity, the gear plate 4-2 has a tendency to rotate clockwise downward, which gives the gear plate 4-2 a certain torque to balance the gravity of the display 8 and ensure that the display 8 does not fall. The display can stop at any position.

[0057] In order to improve the compactness and aesthetics of the structure, a gear plate cover 4-11 and a decorative shell 4-12 are also provided, wherein the gear plate cover 4-11 is annular and is fixed to the flange 4-1 by multiple screws to keep the needle roller assembly 4-3 between the gear plate 4-2 and the flange 4-1, and the decorative shell 4-12 covers the two gravity balance modules and the outer periphery of the transmission chain 4-5 and is fixed to the base plate 1, and avoidance grooves for adjusting the torque are respectively provided on the decorative shell 4-12 and the gear plate cover 4-11. By rotating the locking nut 4-6 to adjust the distance between the locking nut 4-6 and the dial 4-4, the spring piece 4-7 is deformed, thereby adjusting the torque of the flange 4-1.

[0058] In order to improve the stability of the structure, a locking screw 4-10 is further provided, which is threadedly connected to the positioning column 1-1 and abuts against the upper end of the locking nut 4-6 to limit the locking nut 4-6 on the positioning column 1-1.

[0059] like Figure 4 As 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 sliding engagement between the second support member 5 and the first support member 3, a metal inner sleeve 5-1 is provided within 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, which roll in engagement with the first support member 3. Fixed end caps 5-3 are provided at each end 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] The mounting plate 6 is rotatably connected to the other end of the second support member 5 and is used for mounting the display 8. Specifically, the mounting plate 6 is rotatably connected to the second support member 5 via a rotating shaft.

[0061] In order to facilitate the positioning between the display 8 and the mounting plate 6, a plurality of U-shaped grooves 6-1 are provided at the upper end of the mounting plate 6. At the same time, at least two U-shaped rollers 8-1 cooperating with the U-shaped grooves 6-1 are fixed on the display 8. By cooperating with the U-shaped rollers 8-1 and the U-shaped grooves 6-1, the display 8 can be quickly positioned on the mounting plate 6, and then the lower part of the display 8 can be fixed on the mounting plate 6.

[0062] like Figures 5 to 7 As shown, the locking mechanism 7 is arranged on the slider 2-2 and is used to lock the rotating shaft 3-1 on one side. It includes a mounting seat and a locking pin assembly that cooperates with the rotating shaft 3-1. The rotating shaft 3-1 rotates with the mounting seat. A first locking position 3-1b1 and a second locking position 3-1b2 that cooperate with the locking pin assembly are provided on the rotating shaft 3-1. When the locking pin assembly is respectively located in the first locking position 3-1b1 and the second locking position 3-1b2, the mounting plate 6 is respectively in a closed state and a stretched state.

[0063] Specifically, the mounting seat comprises a seat body 7-1 and an end cover 7-2 detachably connected with the seat body 7-1, the seat body 7-1 is provided with an axle hole 7-1a for the rotating shaft 3-1 to extend into and a pin hole 7-1b matched with the locking pin assembly, the rotating shaft 3-1 is rotationally arranged in the axle hole 7-1a, and the locking pin assembly can extend to the first locking position 3-1b1 or the second locking position 3-1b2 through the pin hole 7-1b.

[0064] The locking pin assembly comprises a locking pin 7-3, a first elastic member 7-4 sleeved on the locking pin 7-3 and a pull rope 7-5 connected with the locking pin 7-3, wherein the locking pin 7-3 is arranged in the pin hole 7-1b and extends to the outside of the mounting seat at both ends, and the first elastic member 7-4 makes the locking pin 7-3 have a tendency to move towards the rotating shaft 3-1, so that the locking pin 7-3 is stably kept in the first locking position 3-1b1 and the second locking position 3-1b2. Preferably, the first elastic member 7-4 is a spring.

[0065] The locking pin 7-3 comprises a pull ring part 7-3a, a body part 7-3b, a limiting part 7-3c and a locking part 7-3d arranged in the first support part 3 direction from the sliding block 2-2 in sequence, the outer diameter of the limiting part 7-3c is greater than those of the body part 7-3b and the locking part 7-3d, the first elastic member 7-4 is abutted between the limiting part 7-3c and the mounting seat, and the first locking position 3-1b1 and the second locking position 3-1b2 are limiting openings matched with the locking part 7-3d.

[0066] The rotating shaft 3-1 comprises a rotating shaft body 3-1a, a locking disc 3-1b and a fixed part 3-1c arranged in sequence, wherein the fixed part 3-1c is fixedly connected with the first support part 3 through a screw, 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] In order to improve the stability of the structure, the mounting plate is provided with a magnetic member 3-2, when the mounting plate 6 is in the closed state, the second support part 5 is attached to the bottom plate 1, and the mounting plate 6 is adsorbed on the first support part 3 through the magnetic member 3-2, so as to ensure the stability of the closed structure.

[0068] The mounting process of the display is as follows:

[0069] When it is necessary to install the display 8, the locking pin 7-3 is pulled out through the pull rope 7-5, the locking pin 7-3 is separated from the first locking position 3-1b1, the first support part 3 is rotated so that the second support part 5 is perpendicular to the bottom plate 1, at this time, the locking pin 7-3 is released, and the locking pin 7-3 is kept in the second locking position 3-1b2 under the action of the first elastic member 7-4, so that the mounting plate 6 is in the stretched state (as shown in FIG. 6B). Figure 2The U-shaped roller 8-1 at the back end of the display 8 is installed in the U-shaped slot 6-1 on the mounting plate 6 to position the display 8, and the lower part of the display 8 is fixed on the mounting plate 6 by screws.

[0070] After the display 8 is installed, the locking pin 7-3 is pulled out by the pull rope 7-5, the locking pin 7-3 is disengaged from the second locking position 3-1b2, the first support 3 is rotated so that the second support 5 is attached to the bottom plate 1, the mounting plate 6 is rotated and parallel to the bottom plate 1, and the locking pin 7-3 is released at this time, and the locking pin 7-3 is kept in the first locking position 3-1b1 under the action of the first elastic member 7-4 to keep the mounting plate 6 in a closed state (as shown). Figure 3

[0071] The adjustment process of the left and right positions of the display is as follows:

[0072] When the left and right positions of the display 8 need to be adjusted, the display 8 is pulled, the second support 5 moves along the length direction of the first support 3, and the adjustment of the left and right positions is completed.

[0073] The adjustment process of the height position of the display is as follows:

[0074] When the display 8 is lowered, the first support 3 drives the sliding block 2-2 to move downward along the guide rail 2-1, the transmission chain 4-5 drives the left and right direction gear disc 4-2 to move in the clockwise direction (the gear disc 4-2 on the other side rotates counterclockwise), the needle roller 4-3a rubs against the inner wall of the accommodation space under the action of the second elastic member 4-3b and rotates clockwise, the needle roller 4-3a moves along the direction with small gap in the accommodation space, and is clamped to drive the flange plate 4-1 to move together, the flange plate 4-1 rotates after a certain torsion is set by the locking nut 4-6, so that the gear disc 4-2 has a certain torsion when it rotates clockwise to balance the gravity of the display 8, so that the display 8 will not fall and can be stopped at any position. When the torsion of the flange plate 4-1 needs to be adjusted, the locking nut 4-6 is rotated to point to the appropriate position, the distance between the locking nut 4-6 and the dial 4-4 is adjusted, the spring piece 4-7 is deformed, and the flange plate 4-1 has the required torsion.

[0075] ​When the display 8 is raised, the first support 3 drives the slider 2-2 to move upward, the transmission chain 4-5 drives the gear disc 4-2 on the left or right direction to move in the counterclockwise direction (the gear disc 4-2 on the other side rotates in the clockwise direction), and the needle roller 4-3a moves along the direction with large gap in the containing space. At this time, there is a gap among the gear disc 4-2, the flange disc 4-1 and the needle roller 4-3a, the gear disc 4-2 moves independently without torsion, and the display 8 is raised. When stopping, the gear disc 4-2 has a tendency to rotate in the clockwise direction (the gear disc 4-2 on the other side rotates in the counterclockwise direction) due to the influence of gravity, so that the gear disc 4-2 has a certain torsion to balance the gravity of the display 8 and ensure that the display 8 will not fall off and can stop at any position.

[0076] In summary, the wall hanging can realize the adjustment of the display in the left-right direction and the height direction, is convenient to operate and has good stability.
