Detailed Implementation

[0026] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0027] refer to Figures 1 to 7

[0028] A commercial display wall-mounted lift bracket includes a mounting box 10, a liftable and sliding mounting plate 20 is provided on the front side of the mounting box, and detachable hanging components 30 for connecting to the rear side of the display are vertically attached to both sides of the mounting plate. The mounting box is provided with a manual drive mechanism for manually driving the mounting plate to lift.

[0029] In this embodiment, the manual drive mechanism includes a first connecting rod 41. A fixing block 412 is fixed to the upper rear side of the mounting plate and rotatably connected to the upper end of the first connecting rod via a first longitudinal pin 411. A vertical groove 11 for avoiding the fixing block is provided on the front side of the hanging box. The lower end of the first connecting rod is rotatably connected to a second connecting rod 42 via a second longitudinal pin 421. The middle part of the second connecting rod is rotatably connected to a slider 43 that slides vertically with the hanging box via a third longitudinal pin 431. The hanging box is also vertically provided with a sliding groove 12 that slides with the slider. A third connecting rod 44 is also provided inside the hanging box, the upper end of which is rotatably connected to the lower end of the second connecting rod via a fourth longitudinal pin 441. The lower end of the third connecting rod is rotatably connected to a connecting block 443 fixed in the lower part of the inner cavity of the hanging box via a fifth pin 442. The hanging box is equipped with a hand-crank mechanism that drives the upper end of the third link to swing. The hand-crank mechanism drives the third link to swing, the third link drives the second link to rise and fall and rotate around the slider, the second link drives the first link to move the mounting plate to rise and fall, and finally realizes the rise and fall of the display.

[0030] In this embodiment, to drive the third link to swing around the lower hinge point, the hand-crank mechanism includes a nut seat 45 rotatably connected to the hanging box via a mounting base 451. A traction screw 46 is screwed into the radial threaded hole of the nut seat. One end of the traction screw is connected to a hand-crank assembly extending out of the hanging box, and the other end of the traction screw is rotatably connected to a traction plate 47. The other end of the traction screw passes through the traction plate and is provided with a limit pin. The traction plate is provided with several hanging holes and several elastic bodies 48 are hung thereon. The other end of each elastic body is connected to a drive plate 49, which is provided with hanging holes. The elastic body is a traction spring with hooks at both ends. The two ends of the traction spring are respectively hung on the hanging holes on the traction plate and the drive plate. The drive plate is rotatably connected to the hinge point where the second and third links are hinged, that is, the drive plate, the second link, and the third link are rotatably connected to the same hinge axis (fourth longitudinal pin). When the traction screw moves to the outside of the hanging box, it drives the third link to swing through the traction plate, spring, and drive plate, which in turn drives the second link to rotate around the slider and move upward, and drives the display to rise through the third link; when the traction screw moves to the inside of the hanging box, the display descends under the weight of the display and with the cooperation of the first, second, and third links.

[0031] In this embodiment, in order to drive the traction screw to rotate, the hand-cranked assembly includes a drive rod 50 that is in concave-convex fit with one end of the traction screw and is rotatably connected to it via a radial pin. A clearance hole 16 is provided on one side of the hanging box for the drive rod to pass through, and a crank handle 51 is provided on the end of the drive rod that extends out of the hanging box.

[0032] In this embodiment, the crank handle is provided with an elongated hole 511 that engages with the slot on the drive rod via a pin. The elongated hole helps the crank handle hang down in its natural state, reducing the space occupied.

[0033] In this embodiment, in order to guide the lifting of the mounting plate, guide rods 13 are vertically installed on both sides of the hanging box, and a pair of sliding sleeves 14 that slide with the guide rods are installed on the rear of both sides of the mounting plate. Avoidance grooves 15 for the sliding sleeves to pass through are provided on both sides of the hanging box.

[0034] In this embodiment, in order to connect the mounting plate to the display, the mounting assembly includes a hanging rod 31. The hanging rod is a groove-shaped sheet metal part with closed upper and lower ends. The hanging rod is provided with screw holes and waist-shaped holes at intervals from top to bottom to facilitate connection with the back of the display.

[0035] The mounting plate has forward-protruding slots 21 on both sides of its upper part, and forward-protruding L-shaped hook plates 22 on both sides of its lower part. The upper part of the hanging rod has a hook 311 that mates with the slots, and the lower inner side of the hanging rod has a tensioning hook plate 32. The upper end of the tensioning hook plate has a hook 321 that mates with the L-shaped hook plate. An adjusting bolt 33, screwed onto the lower end of the hanging rod from bottom to top, connects to the lower end of the tensioning hook plate. A spring 34 is fitted onto the adjusting bolt, located between the lower end of the hanging rod and the lower end of the tensioning hook plate. The adjusting bolt adjusts the tightness of the connection between the tensioning hook and the L-shaped hook plate, while the spring helps the tensioning hook exert an upward force.

[0036] The usage method of this commercial display lifting wall mount is as follows: Install the mounting box on the wall or support frame; install the mounting assembly on the back of the monitor, and then connect the mounting assembly to the slot and L-shaped hook plate on the mounting plate. Adjust the tension of the tension hook plate and the L-shaped hook plate by adjusting the adjusting bolts; as needed, drive the traction screw to rotate by cranking the handle of the hand crank assembly, which in turn drives the first link, the second link and the third link to raise and lower the mounting plate, thus completing the height adjustment of the monitor.

[0037] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0038] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0039] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0040] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0041] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
