Technical Field

[0001] This invention patent relates to the technical field of liquid crystal displays. Specifically, it relates to a liquid crystal display with multi-directional adjustment. Background Art

[0002] A liquid crystal display is a display device used for the screen display of televisions and computers. Liquid crystal displays have advantages such as low power consumption, small size, and low radiation, and are widely used in daily life.

[0003] A liquid crystal display includes a body, and a screen body for display is provided on the body. To facilitate the placement and support of the body, a support frame generally needs to be arranged on the body to support the fixation of the body.

[0004] In the prior art, the bottom of the support frame is placed on a desktop or the like, and the body is connected to the support frame, so that the body is in a suspended state. However, since the support frame and the body are fixedly connected as a whole, it is difficult to achieve multi-directional rotation of the body relative to the support frame, resulting in the liquid crystal display being unable to achieve the effect of multi-directional adjustment and difficult to meet actual diverse needs. Summary of the Invention

[0005] The purpose of the present invention is to provide a liquid crystal display with multi-directional adjustment, aiming to solve the problem that the liquid crystal display in the prior art cannot be adjusted in multiple directions.

[0006] The present invention is implemented as follows. A liquid crystal display with multi-directional adjustment includes a body and a support frame. The front part of the body has a screen body for display. The support frame includes a base supported on a desktop and a support rod connected to the base and capable of lateral rotation. A rotating disk that rotates longitudinally relative to the body is provided on the back of the body. The lower end of the support rod is connected to the base, and the upper end of the support rod is connected to the rotating disk, suspending the body above the base.

[0007] The upper end of the support rod bends towards the rotating disk to form a bent section, and the bent section is movably embedded in the rotating disk. A spherical fixed head is connected to the bent section, and a spherical fixed groove is provided in the rotating disk. The fixed head is movably placed in the fixed groove.

[0008] A limiting groove for restricting the longitudinal swing of the body relative to the bent section is provided on the rotating disk. The limiting groove is arranged longitudinally, and the fixed groove penetrates through the middle of the limiting groove and communicates with the limiting groove. Arc-shaped grooves are respectively provided at the top and bottom of the fixed head. The arc-shaped grooves extend along the swing direction of the body relative to the fixed object and are filled with elastic sheets made of elastic materials. The elastic sheets are pressed against by the inner side wall of the fixed groove and are in an elastically compressed deformation state.

[0009] The middle part of the elastic sheet is fixedly connected to the bottom of the arc-shaped groove to form a fixed section. The two sides of the elastic sheet are respectively movably placed in the arc-shaped groove to form movable sections. There is an elastic interval between the end of the movable section and the end of the arc-shaped groove.

[0010] When the body swings longitudinally relative to the fixed head, the fixed section remains fixed, and the movable section is squeezed by the inner side wall of the fixed groove. The movable section elastically deforms towards or away from the elastic interval, so that the position of the body after swinging longitudinally relative to the bending section remains fixed.

[0011] Furthermore, there is a hollow groove in the movable section. The inner end of the hollow groove extends to the fixed section, the outer end of the hollow groove penetrates through the end of the movable section, and the hollow groove extends along the length direction of the movable section.

[0012] Furthermore, the end of the elastic sheet has a cylindrical vacant end facing the elastic interval. The diameter of the vacant end is larger than the thickness of the elastic sheet and extends along the width direction of the elastic sheet.

[0013] Furthermore, a conical groove is provided on the back of the body. There is a protruding position in the middle of the conical groove. The rotating disk is rotatably placed in the conical groove. There is an interval arrangement between the rotating disk and the protruding position to form an internal interval. A rotating shaft is connected between the middle of the rotating disk and the protruding position. The inner end of the rotating shaft is fixedly connected to the protruding position, and the outer end of the rotating shaft is rotatably connected to the middle of the rotating disk.

[0014] Furthermore, the outer periphery of the rotating disk has an outer peripheral ring wall, and the outer periphery of the conical groove has an inner peripheral ring wall that rotates relative to the outer peripheral ring wall. The outer peripheral ring wall is movably abutted against the inner peripheral ring wall.

[0015] Furthermore, a plurality of hole slots are provided on the outer peripheral ring wall. The plurality of hole slots are circumferentially spaced around the outer peripheral ring wall. The hole slots are filled with spherical elastic balls. The lower part of the elastic ball is embedded in the hole slot and is fixedly connected to the hole slot through multiple points. The upper part of the elastic ball extends to the outside of the hole slot.

[0016] A circumferential groove is provided on the inner peripheral ring wall. The circumferential groove is circumferentially arranged along the inner peripheral ring wall. The upper part of the elastic ball is movably placed in the circumferential groove, and the elastic ball is in an elastically compressed deformation state. During the longitudinal rotation of the body relative to the rotating disk, the elastic ball is fixed in the hole slot and elastically moves along the circumferential groove.

[0017] Furthermore, a through elastic cylinder is provided in the internal interval. The rotating shaft passes through the elastic cylinder. The rotating shaft and the elastic cylinder are coaxially arranged. An annular interval is formed between the rotating shaft and the elastic cylinder.

[0018] The inner end of the elastic cylinder is fixedly connected to the inner side wall of the conical groove. The outer end of the elastic cylinder abuts against the rotating disc. During the rotation of the machine body relative to the rotating disc, the outer end of the elastic cylinder abuts against the rotating disc and rotates therewith.

[0019] Furthermore, an annularly arranged positioning groove is provided on the inner side wall of the rotating disc, and the outer end of the elastic cylinder is movably embedded in the positioning groove. During the rotation of the machine body relative to the rotating disc, the outer end of the elastic cylinder rotates circumferentially along the positioning groove.

[0020] Furthermore, an outer cylinder that rotates relative to the rotating shaft is sleeved on the outer periphery of the rotating shaft. A plurality of support bars extend from the outer periphery of the outer cylinder. The plurality of support bars are arranged at intervals along the circumferential direction of the rotating shaft and are also arranged at intervals along the axial direction of the rotating shaft. The inner ends of the support bars are connected to the outer periphery of the outer cylinder, and the outer ends of the support bars are embedded in the elastic cylinder.

[0021] Furthermore, the outer end of the support bar has a bent piece. The bent piece and the support bar are arranged in a bent manner. The bent piece is disposed inside the elastic cylinder and extends along the axial direction of the elastic cylinder.

[0022] Compared with the prior art, for the liquid crystal display screen with multi-directional adjustment provided by the present invention, the support rod can rotate horizontally to realize the horizontal rotation of the machine body. The machine body can rotate longitudinally relative to the rotating disc, and the machine body can swing longitudinally relative to the fixed head, thereby achieving the effect of multi-directional adjustment of the machine body to meet diverse real-world requirements. Additionally, by providing two elastic pieces on the fixed head, when the machine body swings longitudinally relative to the fixed head, the fixed section remains stationary, while the movable section is squeezed and elastically deformed. The elastic pieces apply a reverse pressure and frictional force to the machine body so that the machine body can maintain its position after swinging and avoid slipping of the machine body position.

[0023] In addition, by arranging the limiting groove, during the longitudinal swing of the machine body, the bent section can be embedded in the limiting groove. When the bent section abuts against the end of the limiting section, the machine body swings to the extreme position at this time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Refer to Figures 1-5 As shown, it is a preferred embodiment provided by the present invention.

[0033] A multi-directionally adjustable liquid crystal display screen includes a body 100 and a support frame. The front part of the body 100 has a screen body 101 for display. The support frame includes a base 201 supported on a desktop and a support rod 202 connected to the base 201 and capable of rotating horizontally; a rotating disk 300 that rotates longitudinally relative to the body 100 is provided on the back of the body 100. The lower end of the support rod 202 is connected to the base 201, and the upper end of the support rod 202 is connected to the rotating disk 300, suspending the body 100 above the base 201.

[0034] The support rod 202 itself can rotate horizontally. A rotating structure can be formed in the middle of the support rod 202 to realize the horizontal rotation of the support rod 202. Alternatively, the support rod 202 can be in the form of an inner and outer telescopic rod, and the horizontal rotation of the support rod 202 itself can also be realized.

[0035] The upper end of the support rod 202 is bent toward the rotating disk 300 to form a bent section 203. The bent section 203 is movably inserted into the rotating disk 300; a spherical fixing head 400 is connected to the bent section 203, and a spherical fixing groove is provided in the rotating disk 300, and the fixing head 400 is movably placed in the fixing groove.

[0036] The rotating disk 300 is provided with a limiting groove 301 that restricts the longitudinal swing of the body 100 relative to the bent section 203. The limiting groove 301 is arranged to extend longitudinally, and the fixing groove penetrates through the middle of the limiting groove 301 and communicates with the limiting groove 301; arc grooves are respectively provided at the top and bottom of the fixing head 400. The arc grooves extend along the swinging direction of the body 100 relative to the fixed part in a curved manner. An elastic sheet 500 made of an elastic material is filled in the arc grooves. The elastic sheet 500 is pressed by the inner side wall of the fixing groove and is in an elastically compressed deformation state.

[0037] The middle part of the elastic sheet 500 is fixedly connected to the bottom of the arc groove to form a fixed section 5001. The two sides of the elastic sheet 500 are respectively movably placed in the arc groove to form movable sections 5002. An elastic interval 501 is provided between the end of the movable section 5002 and the end of the arc groove.

[0038] When the body 100 swings longitudinally relative to the fixing head 400, the fixed section 5001 remains fixed, and the movable section 5002 is squeezed by the inner side wall of the fixing groove. The movable section 5002 elastically deforms towards or away from the elastic interval 501, so that the position of the body 100 after swinging longitudinally relative to the bent section 203 is in a fixed state.

[0039] For the multi-directional adjustable liquid crystal display screen provided above, the support rod 202 can rotate horizontally to realize the horizontal rotation of the body 100. The body 100 can rotate longitudinally relative to the rotating disk 300, and the body 100 can swing longitudinally relative to the fixing head 400, thus achieving the effect of multi-directional adjustment of the body 100 to meet diverse real-world requirements; in addition, by providing two elastic sheets 500 on the fixing head 400, when the body 100 swings longitudinally relative to the fixing head 400, the fixed section 5001 remains stationary, and the movable section 5002 will be squeezed and elastically deformed. The elastic sheet 500 reversely applies pressure and friction to the body 100, so that the body 100 can maintain the position after swinging and avoid slipping of the position of the body 100.

[0040] In addition, by arranging the limiting groove 301, during the longitudinal swing of the body 100, the bent section 203 can be inserted into the limiting groove 301. When the bent section 203 abuts against the end of the limiting section, the body 100 swings to the limit position at this time.

[0041] In this embodiment, a hollow groove 503 is provided in the movable section 5002. The inner end of the hollow groove 503 extends to the fixed section 5001, and the outer end of the hollow groove 503 penetrates through the end of the movable section 5002. The hollow groove 503 extends along the length direction of the movable section 5002. In this way, during the longitudinal swing of the body 100, the movable section 5002 is squeezed and deformed. The existence of the hollow groove 503 can guide the deformation direction of the movable section 5002.

[0042] In this embodiment, the end of the elastic sheet 500 has a cylindrical empty end 502 facing the elastic interval 501. The diameter of the empty end 502 is greater than the thickness of the elastic sheet 500 and is arranged along the width direction of the elastic sheet 500. The empty end 502 is cylindrical. When the movable section 5002 is squeezed, due to the arrangement of the empty end 502, the movable section 5002 can be guided to be squeezed and deformed along the length direction.

[0043] In this embodiment, a tapered groove is provided on the back of the body 100. The middle of the tapered groove has a protruding position. The rotating disk 300 is rotatably placed in the tapered groove. There is an internal interval 102 between the rotating disk 300 and the protruding position; a rotating shaft 302 is connected between the middle of the rotating disk 300 and the protruding position. The inner end of the rotating shaft 302 is fixedly connected to the protruding position, and the outer end of the rotating shaft 302 is rotatably connected to the middle of the rotating disk 300.

[0044] By arranging the rotating shaft 302, the rotating disk 300 can be better supported, so that the rotating disk 300 and the body 100 are connected as a whole, and the body 100 can rotate longitudinally relative to the rotating disk 300.

[0045] In this embodiment, the outer periphery of the rotating disk 300 has an outer peripheral ring wall 310, and the outer periphery of the tapered groove has an inner peripheral ring wall that rotates relative to the outer peripheral ring wall 310. The outer peripheral ring wall 310 is movably abutted against the inner peripheral ring wall. Through the cooperation between the outer peripheral ring wall 310 and the inner peripheral ring wall, on the basis of realizing the rotation of the body 100 relative to the rotating disk 300, the fitting connection between the rotating disk 300 and the body 100 can be realized.

[0046] In this embodiment, a plurality of hole slots 308 are provided on the outer peripheral ring wall 310. The plurality of hole slots 308 are arranged at intervals along the circumferential direction of the outer peripheral ring wall 310; the hole slots 308 are filled with elastic balls 301 in a spherical shape. The lower part of the elastic ball 301 is embedded in the hole slot 308 and is fixedly connected to the hole slot 308 through multiple points. The upper part of the elastic ball 301 extends to the outside of the hole slot 308.

[0047] A circumferential groove is provided on the inner peripheral ring wall. The circumferential groove is arranged along the circumferential direction of the inner peripheral ring wall. The upper part of the elastic ball 301 is movably placed in the circumferential groove, and the elastic ball 301 is in an elastically compressed and deformed state; during the longitudinal rotation of the body 100 relative to the rotating disk 300, the elastic ball 301 is fixed in the hole slot 308 and elastically moves along the circumferential groove.

[0048] During the rotation of the body 100 relative to the rotating disk 300, the inner peripheral wall rotates relative to the outer peripheral wall 310, and the elastic balls 301 are squeezed and deformed, which can provide a certain rotational restraint force to ensure that the body 100 rotates to the set position. Secondly, after the body 100 rotates to the set position, the multiple elastic balls 301 are in a squeezed and deformed state, which can exert pressure and friction on the body 100, so that a relatively stable state is maintained between the body 100 and the rotating disk 300, avoiding the phenomenon of rotational slippage between the body 100 and the rotating disk 300.

[0049] In this embodiment, a through-shaped elastic cylinder 303 is provided in the internal space 102. The rotating shaft 302 passes through the elastic cylinder 303, and the rotating shaft 302 and the elastic cylinder 303 are coaxially arranged. An annular space 3031 is formed between the rotating shaft 302 and the elastic cylinder 303.

[0050] The inner end of the elastic cylinder 303 is fixedly connected to the inner side wall of the conical groove, and the outer end of the elastic cylinder 303 abuts against the rotating disk 300. During the rotation of the body 100 relative to the rotating disk 300, the outer end of the elastic cylinder 303 abuts against the rotating disk 300 and rotates.

[0051] When the body 100 rotates relative to the rotating disk 300, the outer end of the elastic cylinder 303 always abuts against the rotating disk 300, which can provide a certain rotational restraint force. And after the body 100 rotates a set angle relative to the rotating disk 300, the elastic cylinder 303 can provide anti-torsion ability to the rotating disk 300, avoiding the phenomenon of rotational slippage between the body 100 and the rotating disk 300.

[0052] In this embodiment, an annularly arranged positioning groove 309 is provided on the inner side wall of the rotating disk 300, and the outer end of the elastic cylinder 303 is movably embedded in the positioning groove 309. During the rotation of the body 100 relative to the rotating disk 300, the outer end of the elastic cylinder 303 rotates circumferentially along the positioning groove 309.

[0053] By arranging the positioning groove 309, the outer end of the elastic cylinder 303 can be restricted and guided, avoiding phenomena such as distortion of the elastic cylinder 303, and ensuring that the outer end of the elastic cylinder 303 always abuts against the rotating disk 300.

[0054] In this embodiment, an outer cylinder 304 that rotates relative to the rotating shaft 302 is sleeved on the outer periphery of the rotating shaft 302. A plurality of support bars 306 extend from the outer periphery of the outer cylinder 304. The plurality of support bars 306 are arranged at intervals along the circumferential direction of the rotating shaft 302 and at intervals along the axial direction of the rotating shaft 302. The inner ends of the support bars 306 are connected to the outer periphery of the outer cylinder 304, and the outer ends of the support bars 306 are embedded in the elastic cylinder 303.

[0055] In this way, by arranging the outer cylinder 304 and the plurality of support bars 306, the rotating shaft 302 and the elastic cylinder 303 are connected into a relative integral structure. During the rotation of the body 100 relative to the rotating disk 300, the circumferential shape of the elastic cylinder 303 can be kept unchanged, and the phenomenon of distortion of the elastic cylinder 303 can be avoided, so as to ensure that the elastic cylinder 303 always abuts between the body 100 and the rotating disk 300.

[0056] In this embodiment, the outer end of the support bar 306 has a bent piece 307. The bent piece 307 is arranged in a bent manner with the support bar 306. The bent piece 307 is built in the elastic cylinder 303 and extends along the axial direction of the elastic cylinder 303. In this way, on the premise that the support bar 306 restricts the circumferential integrity of the elastic cylinder 303, the bent piece 307 can restrict the axial integrity of the elastic cylinder 303, thereby playing a role in restricting and supporting the overall shape of the elastic cylinder 303.

[0057] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
