After the supported object is connected to the first joint, the pitch and lateral adjustment angles have a large range and can be adjusted along the height position. The cross structure has high sturdiness and can bear a large load.

[0007] Furthermore, the cross structure also includes a first limiting buckle and a second limiting buckle. The inner wall of the first joint arm is provided with a first limiting groove, and the inner wall of the second joint arm is provided with a second limiting groove. The first limiting buckle is slidably connected in the first limiting groove, and the second limiting buckle is slidably connected in the second limiting groove, which is used to limit the rotation range of the first joint arm and the second joint arm to prevent damage to the supported object due to excessive rotation.

[0008] Furthermore, the cross structure also includes a first damper and a second damper, with the first damper sleeved on the horizontal axis and the second damper sleeved on the horizontal axis, so that the first joint arm and the second joint arm can stop at any position within the adjustment range, making the adjustment operation convenient.

[0009] Furthermore, the cross structure also includes a first locking bolt and a second locking bolt. The first locking bolt is spirally connected to the horizontal axis and compresses the first damper. The second locking bolt is spirally connected to the vertical axis and compresses the second damper, which is used to change the magnitude of the damping and improve the feel of use.

[0010] Furthermore, the column is equipped with a slide rail and a damping slider. The slide rail is located inside the column, and the damping slider is slidably connected to the slide rail for adjusting the height of the supported object.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0037] Example 1

[0038] like Figures 1-12As shown, this embodiment discloses a screen support device, including a base 1, a column 2, a rotating joint 3, and a seat plate 4. One end of the column 2 is connected to the base 1. The rotating joint 3 is vertically connected to the column 2. The seat plate 4 is disposed on the rotating joint 3. The rotating joint 3 includes a first joint arm 32, a cross structure 33, and a second joint arm 34. The cross structure 33 is provided with a horizontal axis 336 and a vertical axis 337. The horizontal axis 336 is rotatably connected to the first joint arm 32, and the vertical axis 337 is rotatably connected to the second joint arm 34. The first joint arm 32 and the second joint arm 34 rotate perpendicularly to the horizontal axis 336 and the vertical axis 337, respectively, so as to realize the tilt and left and right angle adjustment of the supported object. The tilt adjustment range is 0°-300°, and the left and right adjustment range is 0°-360°, which is a large adjustment range. In addition, the rotating joint 3 can move along the height of the column 2 to realize the height adjustment of the supported object. The cross structure 33 has a simple structure, and by increasing the volume, it can support the movement of high loads.

[0039] Furthermore, the cross structure 33 also includes a first limiting buckle 334 and a second limiting buckle 332. The inner wall of the first joint arm 32 is provided with a first limiting groove 322, and the inner wall of the second joint arm 34 is provided with a second limiting groove 342. The first limiting buckle 334 is slidably connected in the first limiting groove 322, and the second limiting buckle 332 is slidably connected in the second limiting groove 342. The first limiting buckle 334 is set as a plate with a hole. The side wall of the first limiting buckle 334 extends along the axis of the hole to form a protrusion. The protrusion extends into the first limiting groove 322 and plays the role of limiting the rotation range of the first joint arm 32. In addition, a protrusion is also provided on the other side wall of the first limiting buckle 334 for installing and determining the installation position of the first limiting buckle 334. The first limiting buckle 334 and the second limiting buckle 332 have the same structure.

[0040] Furthermore, the cross structure 33 also includes a first damper 333 and a second damper 331. The first damper 333 is sleeved on the horizontal axis 336, and the second damper 331 is sleeved on the horizontal axis 336. The first damper 333 is composed of multiple disc springs. The multiple disc springs generate friction with the first joint arm 32, and the disc springs enable the first joint arm 32 to stop at any position, making it easy to adjust the orientation of the support. The first damper 333 and the second damper 331 have the same structure.

[0041] Furthermore, the cross structure 33 also includes a first locking bolt 335 and a second locking bolt 338. The first locking bolt 335 is screwed onto the horizontal axis 336 and compresses the first damping 333. The second locking bolt 338 is screwed onto the vertical axis 337 and compresses the second damping 331. Adjusting the tightness of the first locking bolt 335 and the second locking bolt 338 adjusts the pressure on the disc spring, thereby changing the feel of adjusting the supported object.

[0042] Furthermore, the column 2 is provided with a slide rail 21 and a damping slider 22. The slide rail 21 is located inside the column 2, and the damping slider 22 is slidably connected to the slide rail 21. The slide rail 21 is arranged along the height direction of the column 2. The damping slider 22 rubs against the inner wall of the column 2 to support the damping slider 22 to stop within the adjustment range.

[0043] Furthermore, the damping slider 22 is provided with a friction block 223 and an elastic coil 224. The friction block 223 is telescopically connected to the damping slider 22 and extends outward. One end of the elastic coil 224 is connected to the friction block 223 and is used to apply outward pressure to the friction block 223. The elastic coil 224 is made of coiled steel strip and is fixed to the damping slider 22 to provide continuous elastic force. Under the action of the elastic force, the friction block 223 extends outward and abuts against the inner wall of the column 2. The friction force generated prevents the damping slider 22 from moving, thereby achieving the function of stopping at any height.

[0044] The damping slider 22 includes a slide 221 and a top cover 222. The slide 221 is slidably connected to the slide rail 21. The slide 221 contains a combination of two sets of friction blocks 223 and elastic coils 224. The top of the slide 221 is provided with a top cover 222 to prevent the elastic coils 224 from shifting.

[0045] Preferably, the first articulated arm 32 is provided with a first shaft hole 321, a first rotating groove 324, and a base 325. The first rotating groove 324 is provided on the first articulated arm 32, and the first shaft hole 321 is provided on the inner wall of the first rotating groove 324. The first articulated arm 32 is detachably connected to the seat plate 4 through the base 325. The horizontal shaft 336 is rotatably connected in the first shaft hole 321 to support the rotation of the first articulated arm 32. One end of the first articulated arm 32 is connected to the base 325, which is used to connect the seat plate 4. The base 325 is provided with a limiting protrusion and a central hole for positioning the base 325 and the seat plate 4. The central hole is used to bolt the two together. More specifically, two support arms 323 protrude from the base 325, and the two support arms 323 form the first rotating groove 324 at intervals. The first shaft hole 321 passes through the two support arms 323, and the horizontal shaft 336 is supported from both ends by the two support arms 323, which improves the load that can be supported and makes the rotation adjustment angle more stable.

[0046] More preferably, the second articulated arm 34 is provided with a positioning plate 341 and a second shaft hole 343. The second shaft hole 343 is provided on the second articulated arm 34, and the positioning plate 341 is provided on the inner wall of the second articulated arm 34. The positioning plate 341 is provided with multiple elastic protrusions around the second shaft hole 343. The elastic protrusions contact the cross structure 33. By subdividing the rotation angle, the accuracy of the adjustment direction and the feel are increased. One end of the first articulated arm 34 is connected to an extension block 31, and the other end of the extension block 31 is connected to a damping slider 22. The extension block 31 lengthens the outward extension distance of the cross structure 33, thereby increasing the angle range of the supported object.

[0047] More preferably, the base 1 is provided with a wire groove 11, which is arranged around the outer side wall of the base 1 and penetrates the base 1 along the length direction of the column 2 to form a through groove 12, which is used to connect power cords and data cables, thereby hiding the cables and improving the aesthetics of use.

[0048] More preferably, a groove is provided in the upper half of the column 2, and the slide rail 21 is provided on both sides of the groove. Both sides of the damping slider 22 are connected to the slide rail 21, which improves the load-bearing capacity of the damping slider 22, makes it slide more smoothly and has a longer service life. A handle hole 23 is provided in the lower half of the column 2, and the handle hole 23 penetrates the column 2 in the front and back direction, making it convenient to grab and use when moving.

[0049] The screen support device is used as follows:

[0050] Connect the supported object to the seat plate 4. Push the first joint arm 32 in the up-down direction to adjust the pitch of the supported object. After adjustment, push the second joint arm 32 in the left-right direction to adjust the angle of the supported object in the left-right direction. After adjustment, push the cross structure 33 along the column 2 to adjust the height of the supported object. If the supported object is heavy or light, the tightness of the first locking bolt 335 and the second locking bolt 338 can be adjusted to improve the load-bearing capacity or the adjustment feel.
