Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a multifunctional artistic TV stand that can be pushed around at will, comprising a push frame 1, a universal wheel fixedly mounted on the lower end of the push frame 1 via a pulley frame, a vertical rod 11 fixedly mounted on the upper end of the push frame 1 in a symmetrical manner, two horizontal rods 12 fixedly mounted between the two vertical rods 11, the two horizontal rods 12 are sequentially arranged from top to bottom, and a support frame 2 is symmetrically mounted on the front side surfaces of the two horizontal rods 12; The rear sides of the two support frames 2 are fixedly connected to two fastening sleeves 21, and a fastening groove is provided at the lower end of each fastening sleeve 21. The two fastening sleeves 21 on the rear side of each support frame 2 are respectively connected with the two cross bars 12, and the fastening grooves of the fastening sleeves 21 are clamped on the cross bars 12 from top to bottom. A locking mechanism is installed at the lower end of each fastening sleeve 21, and the locking mechanism is clamped at the lower end of the cross bar 12. The fastening sleeve 21 is firmly clamped on the cross bar 12 through the provided locking mechanism. The front sides of the two support frames 2 are fixedly installed with a connecting frame 3. A mounting bracket 32 ​​is rotatably mounted on the front side of the connecting bracket 3. The lower end of the rear side of the mounting bracket 32 ​​is rotatably connected to the lower end of the front side of the connecting bracket 3 through a hinge. The upper end of the rear side of the mounting bracket 32 ​​is fixedly connected to a fan-shaped internal tooth plate 34. A through groove is provided at the upper end of the side of the connecting bracket 3. The fan-shaped internal tooth plate 34 passes through the through groove. An adjustment mechanism with a self-locking function is installed on the rear side of the connecting bracket 3. The adjustment mechanism is used to drive the fan-shaped internal tooth plate 34 to move. Protective mechanisms for protecting the corners of the TV are symmetrically installed on the left and right sides of the mounting bracket 32.

[0022] See also Figures 2 to 4 The locking mechanism includes a locking seat 23 which is rotatably installed at the lower end of the fastening sleeve 21 through a pin shaft. One end of the locking seat 23 is fixedly connected to a concave block 24, and a pull rod 25 is movably inserted into the side of the concave block 24. One end of the pull rod 25 passes through the side of the concave block 24 and extends to the inner side thereof. One end of the pull rod 25 on the inner side of the concave block 24 is fixedly connected to a convex locking block 26. The upper end of the raised portion of the convex locking block 26 is provided with an inclined surface 27, and a locking spring 28 is symmetrically fixedly installed on the side of the convex locking block 26. The locking spring 28 and the pull rod 25 are on the same side of the convex locking block 26, and one side of the locking spring 28 abuts against the concave block 24, and the convex locking block 26 is clamped with the fastening sleeve 21.

[0023] A notch is symmetrically cut out at the lower end of the rear side of the fastening sleeve 21 , and the concave block 24 is sleeved on the lower end of the rear side of the fastening sleeve 21 , and the upper end of the concave block 24 abuts against the upper end of the inner side of the notch.

[0024] The upper end of the locking seat 23 is provided with an abutment groove, which abuts the lower end of the cross bar 12 . The rear side surface of the fastening sleeve 21 is provided with a locking groove 22 , and the raised portion of the convex locking block 26 is engaged with the locking groove 22 .

[0025] When the support frame 2 and the crossbar 12 need to be installed, the locking mechanism is in the initial state. At this time, the locking mechanism is not engaged with the fastening sleeve 21, and the locking mechanism is retracted to the inner side of the support frame 2, and the locking mechanism does not close the lower end of the fastening groove of the fastening sleeve 21; During installation, the fastening grooves of the two fastening sleeves 21 on the rear side of the support frame 2 are respectively clamped on the two cross bars 12, and then the locking mechanism is turned upward so that the contact groove of the locking seat 23 abuts the lower end of the cross bar 12, and the concave block 24 is sleeved on the lower end of the rear side of the fastening sleeve 21; When the concave block 24 is sleeved on the lower end of the rear side of the fastening sleeve 21, the concave block 24 drives the inclined surface 27 on the convex locking block 26 to first contact the lower end of the rear side of the fastening sleeve 21. At this time, the inclined surface 27 is pushed by the lower end of the rear side of the fastening sleeve 21, causing the convex locking block 26 to retract and move toward the inside of the concave block 24. At this time, the convex locking block 26 is away from the locking seat 23, and the convex locking block 26 squeezes the locking spring 28. When the concave block 24 rotates to After the appropriate position, the upper end of the concave block 24 abuts against the upper end of the inner side of the notch. At this time, the raised portion of the convex locking block 26 is aligned with the locking groove 22. Under the action of the elastic force of the locking spring 28, the raised portion of the convex locking block 26 is engaged with the locking groove 22, so that the locking seat 23 is firmly stuck on the lower end of the cross bar 12. The fastening sleeve 21 is firmly stuck on the cross bar 12 through the provided locking mechanism, and the support frame 2 is firmly installed on the cross bar 12.

[0026] When it is necessary to disassemble the support frame 2, pull the pull rod 25 to move the protrusion of the convex locking block 26 out of the locking groove 22, and then flip the locking mechanism downward to reset the locking mechanism. At this time, the support frame 2 can be pulled downward to move the fastening groove of the fastening sleeve 21 upward along the cross bar 12, so that the fastening sleeve 21 is separated from the cross bar 12, and the disassembly of the support frame 2 is completed.

[0027] See also Figure 2 and Figure 5The upper end of the connecting frame 3 is symmetrically inserted with an arc-shaped guide sleeve 31, and the arc-shaped guide sleeve 31 is fixedly connected to the connecting frame 3. The upper end of the rear side of the mounting frame 32 is symmetrically fixedly connected with an arc-shaped guide plate 33, which is inserted into the arc-shaped guide sleeve 31, and the arc-shaped guide plate 33 is slidably connected to the arc-shaped guide sleeve 31. The end of the arc-shaped guide plate 33 away from the mounting frame 32 is fixedly sleeved with a limiting sleeve to prevent the arc-shaped guide plate 33 from separating from the arc-shaped guide sleeve 31.

[0028] The curvature of the sector-shaped inner tooth plate 34 and the curvature of the arc-shaped guide sleeve 31 are the same as the curvature of the arc-shaped guide plate 33. The arc-shaped guide plate 33 is coaxial with the hinge axis of the hinge, that is, when the mounting frame 32 is flipped up or down along the hinge, the mounting frame 32 can drive the arc-shaped guide plate 33 to slide stably upward or downward along the arc-shaped guide sleeve 31, so that the mounting frame 32 can rotate forward or backward stably.

[0029] A plurality of mounting holes are provided on the side of the mounting bracket 32 ​​, and the mounting bracket 32 ​​is connected to the rear side of the TV via screws.

[0030] See also Figures 5 to 7 The adjusting mechanism includes a concave seat 4 fixedly mounted on the upper end of the rear side of the connecting frame 3. A plurality of slots 41 are opened on one side of the concave seat 4 in an annular array. A circular shaft 42 is rotatably installed in the concave seat 4. The two ends of the circular shaft 42 respectively pass through the two sides of the concave seat 4. An adjusting gear 43 is fixedly sleeved on the circular shaft 42. The adjusting gear 43 meshes with the fan-shaped internal tooth plate 34. One end of the circular shaft 42 close to the slot 41 is fixedly connected to a polygonal rod 5. A knob 51, a locking spring 52 and an adjusting sleeve 53 are sequentially sleeved on the polygonal rod 5 from the outside to the inside. The knob 51 is fixedly connected to the polygonal rod 5, and the adjusting sleeve 53 is slidably connected to the polygonal rod 5. A plurality of locking blocks 54 are fixedly connected in an annular array on one side of the adjusting sleeve 53 close to the slot 41. An extrusion surface 55 is opened on one side of the locking block 54, and the locking block 54 is engaged with the slot 41.

[0031] A polygonal groove is formed on the side of the adjusting sleeve 53 , and the polygonal rod 5 passes through the polygonal groove. The polygonal groove and the polygonal rod 5 are slidably connected. The two ends of the locking spring 52 are respectively in contact with the knob 51 and the adjusting sleeve 53 , and the locking spring 52 applies elastic force to the adjusting sleeve 53 .

[0032] When the knob 51 is rotated clockwise, the knob 51 drives the polygonal rod 5 to rotate, the polygonal rod 5 drives the circular shaft 42 and the adjusting sleeve 53 to rotate synchronously, the circular shaft 42 drives the adjusting gear 43 to rotate synchronously, and the adjusting gear 43 drives one end of the sector-shaped internal gear plate 34 to rotate backward. At the same time, the sector-shaped internal gear plate 34 drives the mounting bracket 32 ​​to rotate backward, so that the mounting bracket 32 ​​moves closer to the connecting bracket 3; When the adjusting sleeve 53 rotates, the locking block 54 is driven to rotate synchronously. At this time, the extrusion surface 55 of the locking block 54 abuts against the slot 41, so that the locking block 54 moves away from the slot 41, and the locking block 54 drives the adjusting sleeve 53 to slide along the polygonal rod 5 close to the knob 51. At the same time, the adjusting sleeve 53 squeezes the locking spring 52. When the locking block 54 rotates to align with other adjacent slots 41, the elastic force of the locking spring 52 causes the adjusting sleeve 53 to move close to the concave seat 4, and the adjusting sleeve 53 drives the locking block 54 to be clamped into the slot 41. When the knob 51 keeps rotating, the locking block 54 is first moved out of one slot 41 and then clamped into the other adjacent slot 41, and so on. By locking the locking block 54 and engaging the locking slot 41, the adjusting sleeve 53 can only rotate clockwise. At this time, the adjusting sleeve 53 cannot rotate counterclockwise, thereby preventing the polygonal rod 5, the circular shaft 42 and the adjusting gear 43 from rotating counterclockwise, and further preventing the sector-shaped internal gear plate 34 and the mounting bracket 32 ​​from rotating forward, thereby preventing the TV from shaking forward during the pushing of the TV stand.

[0033] When the TV needs to be tilted forward, the adjusting sleeve 53 is first pulled close to the knob 51, and the adjusting sleeve 53 drives the locking block 54 to move out of the slot 41. At this time, the knob 51 is turned counterclockwise, so that the polygonal rod 5 drives the adjusting gear 43 to rotate counterclockwise through the circular shaft 42. The adjusting gear 43 drives the fan-shaped inner tooth plate 34 to move forward, and the fan-shaped inner tooth plate 34 drives the mounting bracket 32 ​​and the motor to tilt forward. After the adjustment is completed, the adjusting sleeve 53 is released, and under the action of the elastic force of the locking spring 52, the adjusting sleeve 53 drives the locking block 54 to engage with the slot 41.

[0034] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 8 The protective mechanism includes a connecting plate 6 fixedly installed on the rear side of the mounting frame 32, and a transmission frame 61 is provided on the side of the connecting plate 6. The transmission frame 61 is symmetrically fixedly connected to a slide plate 62 on the side close to the connecting plate 6. The slide plate 62 passes through the connecting plate 6, and an adjusting screw 63 is inserted through the side of the connecting plate 6. One end of the adjusting screw 63 is fixedly connected to a rotating shaft, which passes through the transmission frame 61, and an adjusting button 64 is fixedly sleeved on the end of the rotating shaft away from the adjusting screw 63. The rotating shaft is rotatably connected to the transmission frame 61, and the adjusting button 64 and the adjusting screw 63 are respectively in rotational contact with the two sides of the transmission frame 61, so that the adjusting button 64, the rotation and the adjusting screw 63 can rotate stably along the transmission frame 61. The upper and lower ends of the transmission frame 61 are symmetrically fixedly connected with fan-shaped plates 7, and a rotatable and adjustable protective component is installed on the side of the fan-shaped plate 7.

[0035] A threaded hole is formed through the side surface of the connecting plate 6 , and a sliding groove is formed through the side surface of the connecting plate 6 symmetrically up and down. The adjusting screw 63 is threadedly connected to the threaded hole, and the slide plate 62 is slidably connected to the sliding groove left and right.

[0036] The protective assembly includes a rotating arm 72 which is rotatably mounted on the end of the transmission frame 61 through a pin shaft. The end of the rotating arm 72 away from the transmission frame 61 is rotatably connected to an L-shaped protective sleeve 73 through a pin shaft. The rotating arm 72 is in rotational contact with the sector plate 7. The L-shaped protective sleeve 73 is clamped with the end corner of the TV. An L-shaped groove is provided on the side of the L-shaped protective sleeve 73. The end corner of the TV is clamped in the L-shaped groove. An arc groove 71 is provided on the side of the sector plate 7. The rotating arm 72 is fixedly connected to the sector plate 7 by bolts and nuts, and the bolts pass through the arc groove 71.

[0037] By rotating the adjusting button 64, the adjusting button 64 drives the adjusting screw 63 to rotate through the rotating shaft, so that the adjusting screw 63 moves left or right along the threaded hole. At the same time, the adjusting screw 63 drives the transmission frame 61 to move left or right, and the transmission frame 61 drives the protective component to move left or right synchronously.

[0038] When it is necessary to adjust the upper and lower positions of the protective assembly, first loosen the bolts and nuts to release the lock between the rotating arm 72 and the fan-shaped plate 7, and rotate the rotating arm 72 to the left or right along the fan-shaped plate 7. The rotating arm 72 drives the L-shaped protective sleeve 73 to rotate to the left or right. After the adjustment is completed, tighten the bolts and nuts so that the nuts are fastened to the side of the rotating arm 72, and the head of the bolt is fastened to the rear side of the fan-shaped plate 7, so that the rotating arm 72 and the fan-shaped plate 7 are relatively fixed, and at the same time, the L-shaped protective sleeve 73 is engaged with the end corner of the TV to protect the end corner of the TV and prevent collision during the movement of the TV, which may cause damage to the TV.

[0039] Working principle: During assembly, the fastening grooves of the fastening sleeve 21 are respectively clamped on the cross bar 12, and then the locking mechanism is turned upward to make the abutting groove of the locking seat 23 abut against the lower end of the cross bar 12. At the same time, under the action of the elastic force of the locking spring 28, the convex part of the convex locking block 26 is clamped with the locking groove 22, so that the locking seat 23 is firmly clamped on the lower end of the cross bar 12. The fastening sleeve 21 is firmly clamped on the cross bar 12 through the provided locking mechanism, and then the support frame 2 is firmly installed on the cross bar 12; Then, the TV and the mounting bracket 32 ​​are locked with screws, and the position of the protective assembly is adjusted to align the L-shaped protective cover 73 with the end corner of the TV. By turning the adjusting button 64, the adjusting button 64 drives the adjusting screw 63 to rotate through the rotating shaft, so that the adjusting screw 63 moves along the threaded hole, and the transmission frame 61 is driven to move by the adjusting screw 63, so that the two transmission frames 61 move closer to each other, and the transmission frame 61 drives the protective assembly to move closer to the TV, so that the L-shaped protective cover 73 is engaged with the end corner of the TV to protect the end corner of the TV.

[0040] When the pushing rack 1 needs to be moved, the pushing rack 1 drives the TV to move synchronously, so that the TV can be moved to a suitable position as needed. The provided adjustment mechanism can prevent the mounting rack 32 from rocking forward during the movement, thereby preventing the TV from rocking forward. The provided protective components can protect the corners of the TV, thereby preventing the TV from being damaged during the movement.

[0041] When the TV needs to be tilted forward, the adjusting sleeve 53 is first pulled close to the knob 51, and the adjusting sleeve 53 drives the locking block 54 to move out of the slot 41. At this time, the knob 51 is turned counterclockwise to cause the adjusting gear 43 to drive the sector-shaped internal gear plate 34 to move forward, and the sector-shaped internal gear plate 34 drives the mounting bracket 32 ​​and the motor to tilt forward. After the adjustment is completed, the adjusting sleeve 53 is released, and under the action of the elastic force of the locking spring 52, the adjusting sleeve 53 drives the locking block 54 to engage with the slot 41, so that the adjusting gear 43 cannot rotate counterclockwise, and the sector-shaped internal gear plate 34, the mounting bracket 32 ​​and the TV cannot be tilted and rotated forward.

[0042] When the TV needs to be rotated backward, the knob 51 is turned clockwise, and the knob 51 drives the polygonal rod 5 to rotate. The polygonal rod 5 drives the circular shaft 42 and the adjustment sleeve 53 to rotate synchronously, so that the adjustment gear 43 drives one end of the sector-shaped internal gear plate 34 to rotate backward. At the same time, the sector-shaped internal gear plate 34 drives the mounting bracket 32 ​​to rotate backward, so that the mounting bracket 32 ​​and the TV move closer to the connecting bracket 3, thereby achieving the adjustment of the TV; When the adjusting sleeve 53 rotates, the locking block 54 is driven to rotate synchronously, so that the locking block 54 is first moved out of one slot 41 and then locked in the other adjacent slot 41, and so on; when the locking block 54 is engaged with the slot 41, the knob 51 and the adjusting sleeve 53 can only rotate clockwise, and the knob 51 and the adjusting sleeve 53 cannot rotate counterclockwise, thereby preventing the polygonal rod 5, the circular shaft 42 and the adjusting gear 43 from rotating counterclockwise, and further preventing the sector-shaped inner tooth plate 34, the mounting bracket 32 ​​and the TV from rotating forward, thereby preventing the TV from shaking forward during the pushing of the TV bracket.
