[0025] Please refer to Figure 1 With Figure 2 , Figure 1 a schematic view of a support 100 provided by an embodiment of the present application, Figure 2 for Figure 1 an exploded schematic view of the support 100 shown in FIG. 1. The support 100 is used to mount a display support. As Figure 1 With Figure 2As shown, the support 100 comprises an upper column 10, a mounting assembly 20, a lower column 30 and a lifting mechanism 40. The upper column 10 is a hollow structure, the mounting assembly 20 is used for mounting a display, and the mounting assembly 20 is fixedly connected with the upper column 10. The lower column 30 is used for being placed on a support table, and the lower column 30 is a hollow structure. The lifting mechanism 40 comprises a hand lever 41, a steering transmission assembly 42, a lifting rod 43 and a sleeve pipe 44. The lifting rod 43 is arranged in the upper column 10, is fixedly connected with the upper column 10 in the extension direction of the upper column 10, and can rotate about the central axis of the lifting rod 43 relative to the upper column 10. The sleeve pipe 44 is sleeved on the lifting rod 43 and is rotationally connected with the lifting rod 43. The sleeve pipe 44 is fixedly arranged in the lower column 30, so that the lower column 30 and the upper column 10 are movably connected through the sleeve pipe 44 and the lifting rod 43. The steering transmission assembly 42 is fixedly connected with the upper column 10 in the extension direction of the upper column 10 and is fixedly connected with the lifting rod 43. The hand lever 41 is fixedly connected with the steering transmission assembly 42 and is located on the same side of the upper column 10 as the side of the mounting assembly 20 for mounting the display. The hand lever 41 is used for being operated to rotate, so that the steering transmission assembly 42 is rotated to drive the lifting rod 43 to rotate in the sleeve pipe 44, so that the lifting rod 43 moves in the direction of approaching or moving away from the sleeve pipe 44, thereby driving the upper column 10 and the mounting assembly 20 to move in the direction of approaching or moving away from the lower column 30.

[0026] The support 100 provided by the embodiment of the present application has the following advantages. By arranging the side of the mounting assembly 20 for mounting the display and the hand lever 41 on the same side of the upper column 10, and by arranging the steering transmission assembly 42 fixedly connected with the hand lever 41 and the upper column 10, the lifting rod 43 fixedly connected with the steering transmission assembly 42, and the sleeve pipe 44 rotationally connected with the lifting rod 43 and fixedly connected with the lower column 30, the user can adjust the height of the mounting assembly 20 by shaking the hand lever 41 from the front and the upper part of the support 100. Therefore, the user can adjust the height of the display from the front of the support 100 in a standing state, which improves the convenience of using the support 100 and the user experience. Moreover, the hand lever 41 is arranged on the front, so that the support 100 can be closely arranged against a wall, thereby reducing the space occupied by the support 100.

[0027] The upper column 10 includes a first side and a second side. The mounting assembly 20 and the hand crank 41 are located on the first side of the upper column 10. The second side is closer to the wall than the first side. The display is mounted on the first side of the upper column 10 through the mounting assembly 20. The plane on which the first side is located can be regarded as the front of the bracket 100. The hand crank 41 is located on the first side, that is, the hand crank 41 is located on the front of the bracket 100.

[0028] The display can be any electronic device with display function, such as a television, commercial display screen, or video wall; the support surface can be the ground, a desktop, or any other surface that can be used to place the bracket 100.

[0029] Please see Figure 3 This is a schematic diagram of the structure of the steering transmission assembly 42 provided in an embodiment of this application. In some embodiments, such as Figure 3 As shown, the steering transmission assembly 42 includes a first steering structure 421, a second steering structure 422, and a rotating shaft 423. The first steering structure 421 is fixedly connected to the hand crank 41. The second steering structure 422 is fixedly connected to the upper column 10 in the extension direction of the upper column 10 and is fixedly connected to the lifting rod 43. The rotating shaft 423 is fixedly inserted through the first steering structure 421 and the second steering structure 422. The hand crank 41 is used for operation to rotate, causing the first steering structure 421 to rotate, which in turn drives the rotating shaft 423 to rotate and the second steering structure 422 to rotate, thereby driving the lifting rod 43 to rotate within the sleeve 44.

[0030] The extension direction of the lifting rod 43 is parallel to the extension direction of the upper column 10 and the extension direction of the sleeve 44, and the extension direction of the sleeve 44 is parallel to the extension direction of the lower column 30.

[0031] The upper column 10 and the lower column 30 may both be tubular, and the diameter of the upper column 10 is smaller than the diameter of the lower column 30 but larger than the diameter of the sleeve 44.

[0032] In some embodiments, the lifting rod 43 is provided with an external thread, and the sleeve 44 is provided with an internal thread that matches the external thread of the lifting rod 43. The lifting rod 43 is threadedly connected to the sleeve 44, and the lifting rod 43 can be screwed into or out of the sleeve 44 by rotation.

[0033] In some embodiments, the sleeve 44 is provided with a nut, which includes a nut body and a rolling body. The nut body can be provided with an inner screw groove matching the outer screw thread of the lifting rod 43. The outer screw thread of the lifting rod 43 and the inner screw groove of the nut body form a circulating screw raceway, and the rolling body is located in the circulating screw raceway. When the lifting rod 43 rotates along the central axis of the lifting rod 43, the rolling body rolls in the circulating screw raceway, and then the lifting rod 43 moves linearly along the axial direction of the lifting rod 43, and the upper stand 10 moves along the axial direction of the lifting rod 43.

[0034] When the hand lever 41 rotates, the first steering structure 421 fixedly connected with the hand lever 41 rotates, and then the second steering structure 422 fixedly connected with the first steering structure 421 rotates, and then the lifting rod 43 fixedly connected with the second steering structure 422 rotates in the sleeve 44, so that the lifting rod 43 rotates into or out of the sleeve 44 along the extension direction of the lifting rod 43, thereby driving the upper stand 10 and the mounting assembly 20 fixedly connected with the upper stand 10 to move in the lower stand 30 along the extension direction of the lifting rod 43. The sleeve 44 is arranged in the lower stand 30. When the lifting rod 43 rotates into the sleeve 44, the upper stand 10 moves close to the lower stand 30, and at least part of the upper stand 10 moves into the lower stand 30. When the lifting rod 43 rotates out of the sleeve 44, the upper stand 10 moves away from the lower stand 30, and the upper stand 10 extends out of the lower stand 30.

[0035] The sleeve 44 is arranged in the lower stand 30, and the lifting rod 43 moves along the direction close to or away from the sleeve 44, that is, moves along the extension direction of the lower stand 30, that is, the upper stand 10 moves along the extension direction of the lower stand 30.

[0036] In some embodiments, the length of the lifting rod 43 can be smaller than the distance between the end of the upper stand 10 close to the lower stand 30 and the mounting assembly 20, so that when the lifting rod 43 is almost entirely rotated into the sleeve 44, the mounting assembly 20 does not collide with the lower stand 30.

[0037] In some embodiments, one end of the sleeve 44 close to the upper stand 10 is flush with one end of the lower stand 30 close to the upper stand 10, so that when the lifting rod 43 moves away from the lower stand 30 and rises to the highest point, the bottom of the lifting rod 43 is flush with the top of the lower stand 30 close to the upper stand 10, which can maximize the length of the lower stand 30 and increase the height adjustment range of the support 100.

[0038] In some embodiments, the length of the sleeve 44 is substantially the same as the length of the lower stand 30, and one end of the sleeve 44 away from the lifting rod 43 is fixedly connected to one end of the lower stand 30 away from the upper stand 10.

[0039] In some embodiments, the support 100 further comprises a support tube 90 and a fastening structure 91, the support tube 90 and the fastening structure 91 are arranged in the lower stand 30, the support tube 90 is fixedly connected to one side of the sleeve 44 away from the lifting rod 43 through the fastening structure 91 to provide support for the sleeve 44, the extension direction of the support tube 90 is parallel to the extension direction of the sleeve 44, and one end of the support tube 90 away from the sleeve 44 is fixedly connected to one end of the lower stand 30 away from the upper stand 10. The sum of the lengths of the support tube 90 and the sleeve 44 is substantially equal to the length of the lower stand 30. By arranging the support tube 90, the shortness of the sleeve 44 can be avoided, which makes it difficult to fix the sleeve 44 in the lower stand 30 and limits the height adjustment range of the support 100.

[0040] The first turning structure 421 is used to turn the rotation direction of the hand lever 41 by 90°, so that the plane in which the rotation direction of the shaft 423 lies is perpendicular to the plane in which the rotation direction of the hand lever 41 lies, and the second turning structure 422 is used to turn the rotation direction of the shaft 423 by 90°, so that the plane in which the rotation direction of the lifting rod 43 lies is perpendicular to the plane in which the rotation direction of the shaft 423 lies and the plane in which the rotation direction of the hand lever 41 lies, so that the rotation of the hand lever 41 in the front direction can be converted into the rotation of the lifting rod 43 along its central axis, and then converted into the movement of the lifting rod 43 in its extension direction, so as to realize the movement of the mounting assembly 20 along the extension direction of the lifting rod 43, i.e. the rising and falling.

[0041] In some embodiments, as shown in FIG. 6, the first turning structure 421 comprises a first turning plate 4211 and a first turning rod 4212, the first turning plate 4211 is fixedly connected to the hand lever 41, and the first turning rod 4212 is fixedly connected to the shaft 423.

[0045] The second bevel gear 4211b and the third bevel gear 4221a are sleeved on the rotating shaft 423 and fixed circumferentially with the rotating shaft 423.

[0046] The shaft intersection angle of the first bevel gear 4211a and the second bevel gear 4211b is 90°, the first bevel gear 4211a is sleeved on the hand lever 41 and fixed circumferentially with the hand lever 41, when the hand lever 41 rotates, the first bevel gear 4211a rotates in the same direction, and the second bevel gear 4211b perpendicular to the first bevel gear 4211a and the rotating shaft 423 fixedly connected with the second bevel gear 4211b also rotate, the rotating direction plane of the second bevel gear 4211b is perpendicular to the rotating direction plane of the first bevel gear 4211a, so as to realize 90° turning of the rotating direction of the hand lever 41, so that the rotating direction plane of the rotating shaft 423 is perpendicular to the rotating direction plane of the hand lever 41.

[0047] The shaft intersection angle of the third bevel gear 4221a and the fourth bevel gear 4221b is 90°, the fourth bevel gear 4221b is sleeved on the lifting rod 43 and fixed circumferentially with the lifting rod 43, when the rotating shaft 423 rotates, the third bevel gear 4221a rotates in the same direction, and the fourth bevel gear 4221b perpendicular to the third bevel gear 4221a and the lifting rod 43 fixedly connected with the fourth bevel gear 4221b also rotate, the rotating direction plane of the fourth bevel gear 4221b is perpendicular to the rotating direction plane of the third bevel gear 4221a, so as to realize 90° turning of the rotating direction of the rotating shaft 423, so that the rotating direction plane of the rotating shaft 423 is perpendicular to the rotating direction plane of the lifting rod 43, so as to realize the rotation of the hand lever 41 into the rotation of the lifting rod 43 along the central axis thereof, and the rotation of the lifting rod 43 is converted into the movement along the extension direction thereof through the rotating connection with the sleeve 44, and the lifting and lowering of the mounting assembly 20 is realized.

[0048] In some embodiments, asFigure 1 and Figure 2 As shown, the upper column 10 includes a first upper column 11 and a second upper column 12 arranged in parallel. The opposite ends of the mounting assembly 20 are fixedly connected to the first upper column 11 and the second upper column 12, respectively. The lower column 30 includes a first lower column 31 and a second lower column 32 arranged in parallel.

[0049] The steering transmission assembly 42 includes two second steering structures 422, such as... Figure 3 As shown, each second steering structure 422 includes a second bevel gear set 4221. The steering transmission assembly 42 includes two second bevel gear sets 4221. The two second bevel gear sets 4221 are respectively disposed in the first upper column 11 and the second upper column 12 and are respectively fixedly connected to the first upper column 11 and the second upper column 12 in the extending direction of the first upper column 11. The rotating shaft 423 is fixedly inserted through the two second bevel gear sets 4221 and extends out of the second upper column 12 on the side away from the first upper column 11. The first bevel gear set 4211 is fixedly sleeved on the part of the rotating shaft 423 that extends out of the second upper column 12. The bracket 100 also includes two lifting rods 43 and two sleeves 44. The two lifting rods 43 are respectively rotatably connected to the two second bevel gear sets 4221. The two sleeves 44 are respectively fixed in the first lower column 31 and the second lower column 32 and respectively sleeve the two lifting rods 43.

[0050] The first bevel gear set 4211 is fixedly sleeved on the part of the rotating shaft 423 that extends out of the second upper column 12. That is, the first bevel gear set 4211 is located on the side of the second upper column 12 away from the first upper column 11, and the hand crank 41 is located on the side of the second upper column 12 away from the first upper column 11. The user can adjust the height from the side of the mounting assembly 20 for easy operation.

[0051] The two third bevel gears 4221a rotate in the same direction, which makes the two fourth bevel gears 4221b rotate in the same direction, and thus the two lifting rods 43 rotate in the same direction, which in turn makes the first upper column 11 and the second upper column 12 move in the same direction.

[0052] In some embodiments, the gear face of the second bevel gear 4211b is away from the third bevel gear 4221a, the gear faces of the two third bevel gears 4221a are away from the second bevel gear 4211b, and the rotation direction of the two third bevel gears 4221a is opposite to the rotation direction of the second bevel gear 4211b.

[0053] The extension direction of the upper stand column 10 is the extension direction of the first upper stand column 11 and the second upper stand column 12. The extension direction of the lower stand column 30 is the extension direction of the first lower stand column 31 and the second lower stand column 32.

[0054] The first upper stand column 11 and the second upper stand column 12 can improve the stability of the display installation. The two second bevel gear sets 4221 can realize the synchronous rising or falling of the first upper stand column 11 and the second upper stand column 12.

[0055] In some embodiments, the first bevel gear set fixing member 4212 is fixed on the side of the second upper stand column 12 away from the first upper stand column 11. The first bevel gear set fixing member 4212 includes a first fixing member body, a first bearing and a second bearing fixed in the first fixing member body. The first fixing member body is fixedly connected to the side of the second upper stand column 12 away from the first upper stand column 11. The first bevel gear 4211a is arranged in the first fixing member body and passes through the first bearing. The first bevel gear 4211a is fixedly connected to the first fixing member body in the extension direction of the upper stand column 10. The second bevel gear 4211b is arranged in the first fixing member body and passes through the second bearing. The second bevel gear 4211b is fixedly connected to the first fixing member body in the extension direction of the upper stand column 10.

[0056] The first bearing and the second bearing are arranged vertically.

[0057] The first bearing includes a first inner ring and a first outer ring. The first outer ring is fixed to the inner wall of the first fixing member body. The first inner ring and the first outer ring are rotationally connected by the first rolling elements between the first inner ring and the first outer ring. The first bevel gear 4211a passes through the first inner ring and is fixed circumferentially to the first inner ring. Therefore, the first bevel gear 4211a can rotate along its central axis relative to the first fixing member body, and is fixedly connected to the first fixing member body in the extension direction of the upper stand column 10.

[0067] Please refer toFigure 1 , Figure 2 , Figure 6 and Figure 7 , Figure 6 for Figure 1 A schematic diagram of the bracket 100 at another angle is shown. Figure 7 for Figure 6 A magnified view of X. In some embodiments, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the bracket 100 further includes a first connector 55, a fixing plate 56, and an anti-tilt structure 57. The first connector 55 is connected between the first upper column 11 and the second upper column 12. The anti-tilt structure 57 is fixedly connected to the first connector 55 and movably connected to the fixing plate 56. The fixing plate 56 is located on the side of the first connector 55 away from the mounting assembly 20. The fixing plate 56 includes a main body 561 and an abutment part 562 fixedly connected to the main body 561. The main body 561 is used to fix to the wall. The anti-tilt structure 57 includes a movable part 571. The movable part 571 abuts against the side of the abutment part 562 near the wall. The movable part 571 is used to move in the same direction on the side of the abutment part 562 near the wall when the lifting rod 43 moves in a direction close to or away from the sleeve 44.

[0068] Among them, such as Figure 7 As shown, the fixing plate 56 has at least one first through hole 563, through which at least one screw can pass and lock into the wall, thereby fixing the fixing plate 56 to the wall. The arrangement direction of the at least one first through hole 563 can be parallel to the extension direction of the fixing plate 56, strengthening the connection between the fixing plate 56 and the wall.

[0069] Among them, such as Figure 6 and Figure 7 As shown, the abutment portions 562 are provided on opposite sides of the main body 561. These opposite sides are located perpendicular to the extending direction of the main body 561. When the main body 561 contacts and is fixed to the wall, a gap exists between the abutment portions 562 and the wall. In other embodiments, the abutment portion 562 may be provided on one of the opposite sides of the main body 561.

[0070] Please see Figure 7 and Figure 8 , Figure 8 for Figure 6 and Figure 7 The diagram shows the structure of the anti-tilting structure 57. Figure 7 and Figure 8As shown, the anti-tilt structure 57 further comprises an anti-tilt main body 572, a fastener 573, a fixing shaft 574 and a locking nut 575. The anti-tilt main body 572 is locked and fixed on the first connecting member 55 by the fastener 573. The fixing shaft 574 penetrates the anti-tilt main body 572 and the movable member 571. The locking nut 575 locks and fixes the fixing shaft 574 on the anti-tilt main body 572, so that the movable member 571 is relatively fixed with the upper stand column 10 in the extension direction of the upper stand column 10. The movable member 571 can be a bearing. The fixing shaft 574 is fixedly penetrated in the inner ring of the bearing of the movable member 571. The outer ring of the bearing of the movable member 571 is rotatable relative to the fixing shaft 574. As shown, Figure 8 As shown, the anti-tilt structure 57 further comprises a gasket 576 arranged between the movable member 571 and the locking nut 575, so as to facilitate the locking of the fixing shaft 574 by the locking nut 575.

[0071] As shown, Figure 7 The side of the abutting portion 562 away from the wall body is in contact with the anti-tilt main body 572. The side of the abutting portion 562 close to the wall body is in contact with the outer ring of the bearing of the movable member 571. The outer ring of the bearing of the movable member 571 can roll along the side of the abutting portion 562 close to the wall body. When the upper stand column 10 moves in the extension direction of the upper stand column 10, the first connecting member 55 and the anti-tilt main body 572 fixedly connected with the first connecting member 55 move in the same direction, thereby driving the outer ring of the bearing of the movable member 571 to roll along the side of the abutting portion 562 close to the wall body.

[0072] The movable part 571 is located on the side of the abutting part 562 close to the wall, that is, the movable part 571 abuts on the side of the abutting part 562 close to the wall. When the display is installed on the mounting assembly 20 and the height of the mounting assembly 20 is adjusted, the bracket 100 is prone to forward inclination due to the weight of the display. The higher the height, the more prone to forward inclination. In the embodiment of the application, the fixing plate 56 is fixed to the wall, and the movable part 571 abuts on the side of the abutting part 562 of the fixing plate 56 close to the wall. When the bracket 100 has a forward inclination tendency, the abutting part 562 can provide a force opposite to the forward inclination direction to the movable part 571, that is, provide a force opposite to the forward inclination direction to the bracket 100, thereby avoiding the bracket 100 from falling down due to the instability of forward inclination. In addition, the movable part 571 can roll on the side of the abutting part 562 close to the wall, so that the movable part 571 can roll on the side of the abutting part 562 close to the wall along with the lifting of the upper stand column 10, thereby avoiding the upper stand column 10 from being unable to lift due to the fixation of the movable part 571 to the wall.

[0073] Please refer to Figure 7 and Figure 9 , Figure 7 The state of the bracket 100 after the movable part 571 moves on the abutting part 562 in the direction away from the lower stand column 30 is shown, Figure 9 The state diagram of the bracket 100 after the movable part 571 moves on the abutting part 562 in the direction close to the lower stand column 30. As Figure 7 shown, when the upper stand column 10 moves in the direction away from the lower stand column 30, the movable part 571 moves on the abutting part 562 in the direction away from the lower stand column 30 to the end of the abutting part 562 away from the support table top. As Figure 9 shown, when the upper stand column 10 moves in the direction close to the lower stand column 30, the movable part 571 moves on the abutting part 562 in the direction close to the lower stand column 30 to the end of the abutting part 562 close to the support table top.

[0074] In some embodiments, as Figure 1 and Figure 2 shown, the bracket 100 further comprises an adjusting part 60. The adjusting part 60 comprises a mounting part 61 and a bent part 62 connected at an angle with the mounting part 61. The mounting part 61 is fixedly installed on the side surface of the lower stand column 30. The bent part 62 is used to be fixed to the wall, so that the lower stand column 30 is fixedly connected with the wall.

[0075] The lower stand 30 can be fixed to the wall through the adjusting member 60, further improving the stability of the support 100.

[0076] As shown in Figure 1 As shown in Figure 2 The support 100 can include a plurality of adjusting members 60 arranged on the side of the first lower stand 31 facing the second lower stand 32 and the side of the second lower stand 32 facing the first lower stand 31, so that the first lower stand 31 and the second lower stand 32 are both fixed to the wall. For example, the support 100 includes four adjusting members 60, two of which have mounting portions 61 arranged along the extension direction of the first lower stand 31 and are fixed to the side of the first lower stand 31 facing the second lower stand 32, and the other two have mounting portions 61 arranged along the extension direction of the second lower stand 32 and are fixed to the side of the second lower stand 32 facing the first lower stand 31.

[0077] In some embodiments, as shown in Figure 1 As shown in Figure 2 The mounting portion 61 is provided with a plurality of first mounting holes 63, the distances between the plurality of first mounting holes 63 and the bent portion 62 are different, so that when the bent portion 62 is fixed to the wall, the distances between the plurality of first mounting holes 63 and the wall are different. The side surface of the lower stand 30 is provided with a second mounting hole 33 for connecting with different first mounting holes 63 to adjust the distance between the lower stand 30 and the wall.

[0078] The plurality of first mounting holes 63 can include a plurality of rows of first mounting holes 63 arranged in a direction parallel to the extension direction of the lower stand 30, and each row of first mounting holes 63 is arranged in a direction perpendicular to the extension direction of the lower stand 30.

[0079] The angle between the mounting portion 61 and the bent portion 62 can be 90°, and the plurality of first mounting holes 63 can be arranged in a direction perpendicular to the bent portion 62, so that the distances between the plurality of first mounting holes 63 and the bent portion 62 are different, and when the bent portion 62 is fixed to the wall, the distances between the plurality of first mounting holes 63 and the wall are different.

[0080] When the first mounting hole 63 closest to the bent portion 62 in the plurality of first mounting holes 63 is connected with the second mounting hole 33, the side of the bent portion 62 close to the wall is flush with the side of the lower stand 30 close to the wall, so that when the first mounting hole 63 closest to the bent portion 62 is connected with the second mounting hole 33, the lower stand 30 can be close to the wall.

[0081] The side of the lower column 30 for mounting the mounting portion 61 is provided with the second mounting hole 33, that is, the side of the first lower column 31 facing the second lower column 32 and the side of the second lower column 32 facing the first lower column 31 are both provided with the second mounting hole 33. The first mounting hole 63 can be connected with the second mounting hole 33 by screwing a bolt into any one of the plurality of first mounting holes 63 and the second mounting hole 33, so that the distance between the first lower column 31 and the second lower column 32 and the wall can be adjusted.

[0082] When the first mounting hole 63 closest to the bending portion 62 in the plurality of first mounting holes 63 is connected with the second mounting hole 33 of the first lower column 31, the side of the bending portion 62 close to the wall is flush with the side of the first lower column 31 close to the wall, so that when the first mounting hole 63 closest to the bending portion 62 is connected with the second mounting hole 33, the first lower column 31 can be close to the wall.

[0083] When the first mounting hole 63 closest to the bending portion 62 in the plurality of first mounting holes 63 is connected with the second mounting hole 33 of the first lower column 31, the side of the bending portion 62 close to the wall is flush with the side of the first lower column 31 close to the wall, so that when the first mounting hole 63 closest to the bending portion 62 is connected with the second mounting hole 33, the first lower column 31 can be close to the wall.

[0084] Please refer to Figures 10 to 12 The different first mounting holes 63 of the mounting portion 61 are connected with the second mounting hole 33 of the first lower column 31. In some embodiments, the mounting portion 61 includes three first mounting holes 63, as shown in Figure 10 The first mounting hole 63 of the mounting portion 61 farthest from the bending portion 62 is connected with the second mounting hole 33 of the first lower column 31, the mounting portion 61 protrudes from the side of the first lower column 31 close to the wall, and the distance between the first lower column 31 and the wall is S1. As shown in Figure 11 The first mounting hole 63 of the mounting portion 61 located in the middle is connected with the second mounting hole 33 of the first lower column 31, the mounting portion 61 protrudes from the side of the first lower column 31 close to the wall, and the distance between the first lower column 31 and the wall is S2, S2 is less than S1. As shown in Figure 12As shown, the first mounting hole 63 of the mounting portion 61 closest to the bending portion 62 is connected with the second mounting hole 33 of the first lower upright column 31, and the side of the bending portion 62 close to the wall is flush with the side of the first lower upright column 31 close to the wall, and the distance between the first lower upright column 31 and the wall is S3, which is almost 0.

[0085] Therefore, by connecting different first mounting holes 63 with the second mounting hole 33, the distance between the first lower upright column 31 and the wall can be adjusted to meet different wall installation environments, such as the presence of a skirting line, wall socket, and wall wiring, etc.

[0086] Obviously, the number of the first mounting holes 63 can be set according to actual needs.

[0087] As shown in the drawings, the first lower upright column 31 and the second lower upright column 32 are arranged on the same horizontal plane, and the distance between the first lower upright column 31 and the second lower upright column 32 is S2. Figure 2 As shown, the bending portion 62 can be provided with a second through hole 621, and the bending portion 62 can be fixed to the wall by penetrating the bending portion 62 with a bolt.

[0088] The second mounting hole 33 of the first lower upright column 31 and the second mounting hole 33 of the second lower upright column 32 can be respectively connected with the first mounting hole 63 at the same position on the corresponding mounting portion 61, so that the distance between the first lower upright column 31 and the second lower upright column 32 and the wall is the same, which is conducive to the stable fixation of the bracket 100 on the wall.

[0089] In some embodiments, the upper upright column 10 and the lower upright column 30 are both tubular, and the pipe diameter of the upper upright column 10 is smaller than the pipe diameter of the lower upright column 30. As shown, Figure 2 As shown, the bracket 100 further comprises an upper pipe sleeve 13 and a lower pipe sleeve 34. The upper pipe sleeve 13 is fixedly sleeved on the end of the upper upright column 10 close to the lower upright column 30, i.e., fixedly sleeved on the bottom of the upper upright column 10. The pipe diameter of the upper pipe sleeve 13 is smaller than the pipe diameter of the lower upright column 30. The lower pipe sleeve 34 is fixedly arranged on the inner wall of the end of the lower upright column 30 close to the upper upright column 10, i.e., fixedly arranged on the top of the lower upright column 30. The pipe diameter of the lower pipe sleeve 34 is greater than the pipe diameter of the upper upright column 10.

[0091] The upper pipe sleeve 13 and the lower pipe sleeve 34 can be made of materials with low friction coefficients, such as brass, polytetrafluoroethylene, etc.

[0092] The sum of the outer diameter of the upper sleeve 13 and the outer diameter of the upper column 10 is substantially equal to the inner diameter of the lower column 30, and the sum of the outer diameter of the lower sleeve 34 and the outer diameter of the upper column 10 is substantially equal to the inner diameter of the lower column 30. When the upper column 10 moves in the extension direction of the upper column 10 within the lower column 30, the upper column 10 is in contact with the inner wall of the lower column 30 through the upper sleeve 13, so that the lower column 30 can serve as a fixed support for the upper column 10 to avoid the upper column 10 being suspended within the lower column 30, and the lower friction coefficient of the upper sleeve 13 is beneficial to the movement of the upper column 10 along the inner wall of the lower column 30; the upper column 10 penetrates the lower sleeve 34, and the lower sleeve 34 is in contact with the outer wall of the upper column 10, so that the lower column 30 can further serve as a fixed support for the upper column 10, and the lower friction coefficient of the lower sleeve 34 is beneficial to the movement of the upper column 10.

[0096] In the first upper tube sleeve 131, the outer diameter of the first upper tube sleeve 131 and the outer diameter of the first upper stand 11 are approximately equal to the inner diameter of the first lower stand 31. When the first upper stand 11 moves along the extension direction of the first upper stand 11 in the first lower stand 31, the first upper stand 11 contacts the inner wall of the first lower stand 31 through the first upper tube sleeve 131, so that the first lower stand 31 can provide a fixed support for the first upper stand 11 to avoid the first upper stand 11 being suspended in the first lower stand 31, and the first upper tube sleeve 131 has a low friction coefficient, which is beneficial to the movement of the first upper stand 11 along the inner wall of the lower stand 30. The first upper stand 11 penetrates the first lower tube sleeve 341, and the first lower tube sleeve 341 contacts the outer wall of the first upper stand 11, so that the first lower stand 31 can further provide a fixed support for the first upper stand 11, and the first lower tube sleeve 341 has a low friction coefficient, which is beneficial to the movement of the first upper stand 11.

[0097] In the second upper tube sleeve 132, the outer diameter of the second upper tube sleeve 132 and the outer diameter of the second upper stand 12 are approximately equal to the inner diameter of the second lower stand 32. When the second upper stand 12 moves along the extension direction of the second upper stand 12 in the second lower stand 32, the second upper stand 12 contacts the inner wall of the second lower stand 32 through the second upper tube sleeve 132, so that the second lower stand 32 can provide a fixed support for the second upper stand 12 to avoid the second upper stand 12 being suspended in the second lower stand 32, and the second upper tube sleeve 132 has a low friction coefficient, which is beneficial to the movement of the second upper stand 12 along the inner wall of the second lower stand 32. The second upper stand 12 penetrates the second lower tube sleeve 342, and the second lower tube sleeve 342 contacts the outer wall of the second upper stand 12, so that the second lower stand 32 can further provide a fixed support for the second upper stand 12, and the second lower tube sleeve 342 has a low friction coefficient, which is beneficial to the movement of the second upper stand 12.

[0098] In some embodiments, as shown in FIG. 1, Figure 1 As shown in FIG. 1, Figure 2 The support 100 further includes at least one second connecting member 70 connected between the first lower stand 31 and the second lower stand 32 to fix the first lower stand 31 and the second lower stand 32, so that the first lower stand 31 and the second lower stand 32 are relatively fixed.

[0099] The support 100 can include a plurality of second connecting members 70, which are arranged in parallel with the first lower vertical column 31 and the second lower vertical column 32. Figure 1 As shown in Figure 2 The support 100 can include two second connecting members 70, which are connected to the first lower vertical column 31 and the second lower vertical column 32, respectively.

[0102] As shown in Figure 13 and Figure 15 The hanging member 22 further includes a locking member 223, which is arranged on the side of the second hanging groove 222 away from the first hanging groove 221, and the end of the locking member 223 abuts against the fixing member 21, so that the hanging member 22 is fixed on the fixing member 21.

[0103] The fixing member 21 and the hanging member 22 can be quickly positioned and mounted through the clamping groove and protruding part clamping mode.

[0104] Wherein, as shown in Figure 15 The locking member 223 can be a threaded rod. After the first and second protruding portions 211 and 212 of the fixing member 21 are respectively engaged with the first and second clamping grooves 221 and 222 of the clamping member 22, the threaded rod is tightened to abut against the fixing member 21 and to have a large abutting force between the threaded rod and the fixing member 21, so that the clamping member 22 is fixed to the fixing member 21.

[0105] In some embodiments, as shown in Figure 1 With Figure 2 The support 100 further includes an adjusting foot 80 fixed to an end of the lower upright column 30 away from the upper upright column 10, and the adjusting foot 80 is used to adjust the distance between the lower upright column 30 and the supporting table top.

[0106] The adjusting foot 80 includes a threaded portion and an adjusting foot body. An end of the lower upright column 30 away from the upper upright column 10 is provided with a threaded hole having an internal thread matched with an external thread of the threaded portion. The distance between the lower upright column 30 and the supporting table top can be adjusted by adjusting the depth of the adjusting foot 80 screwed into the threaded hole. The adjusting foot body is used to be placed on the supporting table top.
