[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The present invention relates to a display stand. For example, the display stand comprises an arc-shaped support bar, a sleeve bar, a first support tube, a second support tube and a mounting plate. For example, the arc-shaped support bar is supported on a desktop, the sleeve bar is sleeved and fixed on the arc-shaped support bar, and the first support tube is fixed to the middle position of the sleeve bar. For example, the second support tube can be installed on the first support tube in a liftable manner, and the mounting plate is installed on the second support tube for mounting a display.

[0027] See also Figure 1 and Figure 2 A monitor stand comprises an arc-shaped support bar 10, a sleeve bar 20, a first support tube 30, a second support tube 40 and a mounting plate 50. The arc-shaped support bar 10 is supported on a desktop, the sleeve bar 20 is sleeved and fixed on the arc-shaped support bar 10, the first support tube 30 is fixed to the middle position of the sleeve bar 20, the second support tube 40 is liftably mounted on the first support tube 30, and the mounting plate 50 is mounted on the second support tube 40 for mounting a monitor.

[0028] For example, when the monitor stand is in use, the curved support bar 10 is used to support the desktop, and the monitor is mounted on the mounting plate 50, so that the monitor stand can be used to support the monitor. Since the curved support bar 10 is curved, it can provide a relatively stable supporting force, and since the area of ​​the curved support bar 10 is smaller than that of the plate-shaped base, it occupies a smaller area of ​​the desktop, allowing more other objects to be placed on the desktop.

[0029] For example, in order to improve the supporting stability of the arc-shaped support bar 10, the arc-shaped support bar 10 includes a first arc segment 11 and a second arc segment 12 connected to each other, and the first arc segment 11 and the second arc segment 12 surround a section of a circle. The arc-shaped support bar 10 is made of metal material, and the central angle formed by the arc-shaped support bar 10 is less than 180 degrees. The first arc segment 11 and the second arc segment 12 are cast and integrally formed by alloy material. A transverse bar 25 is protruding from the middle of the sleeve bar 20, and the first support tube 30 is vertically protruding at the end position of the transverse bar 25, and the diameter of the first support tube 30 is 3-5 times the width of the transverse bar 25. Since the arc-shaped support bar 10 is cast from an alloy material, it has a high hardness, is not easy to deform, and can provide a large supporting force.

[0030] For example, in order to facilitate the installation of the display, the mounting plate 50 is a rectangular mounting plate, and a mounting rib 51 is convexly provided on the periphery thereof, and the mounting plate 50 is made of metal material. A positioning top column 55 is convexly provided in the middle of the mounting plate 50, and the positioning top column 55 is a circular column, and a plurality of mounting notches 58 are concavely provided on the mounting rib 51. The first support tube 30 and the second support tube 40 are both circular tubes, and the inner diameter of the second support tube 40 is larger than the inner diameter of the first support tube 30. An embedding groove 28 is concavely provided on the bottom surface of the sleeve strip 20, and the arc-shaped support strip 10 is embedded in the embedding groove 28. By providing the rectangular mounting plate 50 and convexly providing the mounting rib 51 on the mounting plate 50, it is relatively convenient to install a display, such as a liquid crystal display.

[0031] For example, the present invention also provides a method for casting the above-mentioned display bracket. The method for casting the display bracket comprises the following steps: using alloy material to cast the arc-shaped support bar 10;

[0032] The sleeve strip 20 is formed on the arc-shaped support strip 10 by injection molding;

[0033] The first support tube 30 , the second support tube 40 and the mounting plate 50 are sequentially mounted on the sleeve strip 20 to form the display bracket.

[0034] For example, it is particularly important to facilitate the lifting and lowering of the second support cylinder 40. Figures 3 to 6The display bracket is a computer LCD screen bracket. The top of the first support tube 30 is provided with a first threaded section 31. The second support tube 40 includes a second threaded section 41, a threaded half-tube 42 and a tight half-tube 43. The second threaded section 41 is cylindrical and sleeved on the first support tube 30. The second threaded section 41 is screwed on the first threaded section 31 of the first support tube 30. The threaded half-tube 42 is fixedly protruded on one side of the top of the second threaded section 41. The threaded half-tube 42 extends upward along the axial direction of the second support tube 40. The mounting plate 50 is fixedly mounted on the threaded half-tube 42. The threaded half-tube 42 is provided with a thread on one side away from the mounting plate 50. The first threaded section 31 is also used to be screwed on the threaded half-tube 42. A sliding plate 44 is protruded from the top of the second threaded section 41 on the side away from the threaded half-cylinder 42, and the sliding plate 44 extends toward the side away from the threaded half-cylinder 42. A sliding groove 441 is provided in the sliding plate 44, and sliding grooves 442 are respectively recessed on the opposite sides of the sliding groove 441. A pivot shaft 431 is protruded from the bottom end of the pressing half-cylinder 43, and two avoidance grooves are recessed. The two avoidance grooves are respectively located at the opposite ends of the pivot shaft 431. The pivot shaft 431 is slidably provided in the sliding groove 441, and the opposite ends of the pivot shaft 431 are respectively slidably inserted in the two sliding grooves 442. The opposite sides of the sliding plate 44 are respectively located in the two avoidance grooves, so that the pressing half-cylinder 43 can slide along the sliding plate 44 and rotate around the pivot shaft 431. An elastic pressing pad is provided on one side of the pressing half-cylinder 43 facing the threaded half-cylinder 42. The elastic pressing pad is a concave arc-shaped pad. A first through hole 421 is provided on the top of the threaded half-cylinder 42. A second through hole 430 and an adjustment through hole 432 are provided on the top of the pressing half-cylinder 43. The adjustment through hole 432 is located between the first through hole 421 and the second through hole 430. The display bracket also includes a storage component 60. The storage component 60 includes an insert 61. The insert 61 includes an insert frame 611 and an elastic plug body 613. The insert frame 611 includes a connecting rod 6111 and two insert strips 6113. The two insert strips 6113 are respectively vertically protruded at opposite ends of the connecting rod 6111. The elastic plug body 613 is fixed to the middle of the connecting rod 6111 and protruded between the two insert strips 6113. The two inserting strips 6113 are used to be inserted into the first through hole 421 and the second through hole 430 respectively, so that the elastic plug body 613 is pressed and sealed against the top of the adjusting through hole 432, and the abutting half cylinder 43 and the threaded half cylinder 42 are pressed against each other to clamp the first threaded section 31 of the first supporting cylinder 30. One side of the first threaded section 31 is screwed on the threaded half cylinder 42, and the other side is pressed against the abutting half cylinder 43, so that the second supporting cylinder 40 is fixed on the first supporting cylinder 30.The elastic abutment pad can wipe the rust on the first thread segment 31 at the top of the first support tube 30 during the rotation of the first thread segment 31, and remove the particles on the first thread segment 31 to prevent the first thread segment 31 from being damaged during the rotation and screwing. For example, the top of the first thread segment 31 and the top of the threaded half tube 42 are spaced apart from each other, that is, the insertion frame 611 does not interfere with the first thread segment 31.

[0035] Furthermore, for example, in order to facilitate the locking of the computer keyboard when not in use and to prevent the computer from occupying the desktop area, a stopper strip 426 is provided at one end of the slide plate 44 away from the threaded half cylinder 42, which is used to stop the pivot shaft 431 to prevent the pivot shaft 431 from sliding out of the slide plate 44. In order to facilitate the positioning of the abutting half cylinder 43, a first positioning cylinder 437 is provided at one side of the middle of the abutting half cylinder 43 away from the threaded half cylinder 42, and a second positioning cylinder 427 is provided on the stopper strip 426. The first positioning cylinder 437 and the second positioning cylinder 427 are arranged parallel to each other and are both perpendicular to the axis of the second support cylinder 40. A rectangular positioning groove 4271 is provided in each of the first positioning tube 437 and the second positioning tube 427. The storage assembly 60 further includes a positioning frame 63, and the positioning frame 63 includes a positioning plate 631 and two insertion rods 632. The two insertion rods 632 are respectively vertically protruded at two opposite sections of the positioning plate 631. The cross-sections of the two insertion rods 632 are both rectangular surfaces. The two insertion rods 632 are respectively matched with the rectangular positioning groove 4271 of the first positioning tube 437 and the rectangular positioning groove 4271 of the second positioning tube 427. 632 are respectively movably inserted in the two rectangular positioning grooves 4271, so that the pressing half-cylinder 43 moves away from the threaded half-cylinder 42 and forms a clamping gap with the threaded half-cylinder 42, and the clamping gap is used to insert the computer keyboard. The two insertion strips 6113 of the insertion frame 611 are also used to be inserted into the first perforation 421 and the adjustment perforation 432 respectively to position the pressing half-cylinder 43, and make the elastic plug body 613 elastically press against the computer keyboard in the clamping gap, so that the computer keyboard is clamped in the clamping gap. For example, the length direction of the computer keyboard is perpendicular to the height direction of the second support cylinder 40. The elastic pressing pad of the pressing half-cylinder 43 is also used to elastically press against multiple keys of the computer keyboard to prevent damage to the computer keyboard. By using the mutual matching of the rectangular positioning groove 4271 and the positioning frame 63, the position of the pressing half-cylinder 43 can be accurately and repeatedly positioned, so that the clamping gap can be formed. The arrangement of the insert rod 632 can ensure that the top of the half cylinder 43 will not turn over due to force, and the elastic plug body 613 can elastically position the computer keyboard.

[0036] For example, a pressing spring is provided between the first positioning cylinder 437 and the second positioning cylinder 427, and a chamfer 439 is formed at the bottom of the pressing half cylinder 43 facing the threaded half cylinder 42. When the computer display is used, the positioning frame 63 is first pulled out, and then the plug-in 61 is pulled out, and the computer keyboard can be taken out from the top. The pressing half cylinder 43 is turned over and pressed against the threaded half cylinder 42 under the action of the pressing spring. The pressing half cylinder 43 can be positioned again by pushing the pressing half cylinder 43 by hand and inserting the plug-in 61 into the first through hole 421 and the second through hole 430 at the same time, so that the clamping gap disappears. At this time, the first support cylinder 30 can be rotated relative to the second support cylinder 40 to adjust the height of the computer display. That is, the second support cylinder 40 does not move, and the first support cylinder 30 drives the arc support bar 10 to rotate multiple times, that is, rotates multiple 360-degree angles, so as to change the sum of the lengths of the first support cylinder 30 and the second support cylinder 40, so as to change the height of the computer display. For example, when the keyboard is in use, that is, after the clamping gap disappears, it is convenient to position the display and place the positioning frame 63. The top of the elastic plug body 613 is convexly arranged on the top of the insertion frame 611, and the top of the elastic plug body 613 is concavely provided with a slot 6135. When the computer keyboard is removed, the slot 6135 of the elastic plug body 613 is used to accommodate one of the insertion rods 632 of the positioning frame 63, and the other insertion rod 632 is used to abut against the back of the computer display or be clamped on the front of the computer display to position the computer display. At the same time, the positioning frame 63 will not be lost at will after being removed from the first support tube 30.
