[0030] 1-8 , which are preferred embodiments of the present invention.

[0031] The double-adjustable display device bracket includes an upper support seat 1, a base 2, a support frame 3 and an adjustment structure 4. The upper support seat 1 is used to place the display device 7. The two ends of the support frame 3 are hinged to the upper support seat 1 and the base 2 respectively; the adjustment structure 4 includes a handle 41, a rotating block 42, a push block 43, an upper fixed gear 44, an upper sliding gear 45, a swing arm 46, a lower fixed gear 47 and a lower sliding gear 48. The handle 41 is connected to the rotating block 42, and the handle 41 is used to drive the rotating block 42 to rotate. The rotating block 42 is used to push the push block 43 to move along the axial direction. The push block 43 is connected to the upper sliding gear 45, and the upper fixed gear 44 and the upper sliding gear 45 are engaged and locked or released and unlocked; the swing arm 46 is installed on the support frame 3, the upper part of the swing arm 46 is connected to the upper sliding gear 45, and the lower part of the swing arm 46 is connected to the lower sliding gear 48. The swing arm 46 is swung by the driving force, and the lower fixed gear 47 and the lower sliding gear 48 are engaged and locked or released and unlocked.

[0032] When the above-mentioned dual-adjustment display device bracket needs to be adjusted, the user presses the handle 41 to drive the rotating block 42 to rotate. The rotation of the rotating block 42 pushes the push block 43 to move toward the upper fixed gear 44. The push block 43 moves and pushes the upper sliding gear 45 to move until the upper sliding gear 45 is separated from the upper fixed gear 44. At this time, the upper sliding gear 45 prompts the swing arm 46 to swing, and the swing of the swing arm 46 prompts the lower sliding gear 48 to be separated from the lower fixed gear 47, thereby realizing the angle adjustment between the upper support 1 and the support frame 3, and at the same time, realizing the angle adjustment of the support frame 3 and the base 2, thereby realizing the height adjustment of the support frame 3; in this way, the user can quickly realize the angle and height adjustment of the display device 7 by directly pressing the handle 41.

[0033] The upper support seat 1 is provided with a rotation limiting block 11, and the push block 43 has a push groove 432. The rotation limiting block 11 is embedded in the push groove 432, and the rotation limiting block 11 is used to limit the rotation of the push block 43; in this way, under the action of the rotation limiting block 11, the rotation of the push block 43 is limited, so that when the push block 43 is pushed, it is moved in the direction away from the rotating block 42, thereby realizing the driving of the swing arm 46, and synchronously realizing the separation of the lower fixed gear 47 and the lower sliding gear 48.

[0034] The rotating block 42 has a curved surface 421, and the pushing block 43 has a curved surface 431. The curved surface 421 and the pushing surface 431 are arranged in a curved shape, and the curved surface 421 and the pushing surface 431 are arranged correspondingly. The curved surface 421 rotates and pushes the pushing surface 431 to move in the diverging direction; in this way, under the cooperation of the curved surface 421 and the pushing surface 431, the rotating block 42 rotates and pushes the pushing block 43 to move toward the upper fixed gear 44.

[0035] At the same time, since the spiral surface 421 and the push curved surface 431 are respectively arranged in a curved shape, the pushing stability is better, and the movement stability of the push block 43 is enhanced.

[0036] The rotating block 42 has two curved surfaces 421, and the pushing block 43 has two curved pushing surfaces 431. The two curved surfaces 421 are symmetrically arranged, and the two curved pushing surfaces 431 are symmetrically arranged. The two curved surfaces 421 and the two curved pushing surfaces 431 are arranged in a one-to-one correspondence; in this way, the rotating block 42 applies a pushing force synchronously at both ends, prompting the pushing block 43 to receive the pushing force at two locations at the same time, making the movement of the pushing block 43 more stable.

[0037] The adjustment structure 4 includes a pushing column, one end of which is connected to the push block 43, and the other end of which is penetrated by the rotating block 42. The pushing column is used to limit the radial offset of the rotating block 42 and the pushing block 43; under the action of the pushing column, the radial offset is limited, so that the rotating block 42 and the pushing block 43 are aligned and arranged in the radial direction to avoid offset and ensure the thrust transmission between the rotating block 42 and the pushing block 43.

[0038] The adjustment structure 4 includes an upper fixed column, one end of which is connected to the upper sliding gear 45, and the other end of the upper fixed column extends through the upper fixed gear 44 and is provided with a push block 43; under the action of the upper fixed column, it limits the radial deviation and ensures the cooperation between the upper sliding gear 45, the upper fixed gear 44 and the push block 43.

[0039] The upper sliding gear 45 includes an upper gear seat and an upper gear body, the upper gear seat and the upper gear body are connected, and the upper gear body is engaged and locked or loosened and unlocked with the upper fixed gear 44; the adjustment structure 4 includes an upper return spring 5, one end of the upper return spring 5 is fixed, and the other end of the upper return spring 5 is connected to the upper gear seat, and the upper return spring 5 is used to apply a return elastic force to cause the upper fixed gear 44 and the upper gear body to be engaged and locked.

[0040] In this way, when the pushing force is greater than the elastic force of the upper return spring 5, the upper sliding gear 45 overcomes the elastic force and is separated from the upper fixed gear 44, thereby adjusting the angle between the upper support 1 and the support frame 3, and thus adjusting the presentation angle of the display device 7. After the adjustment, the pushing force is withdrawn, and under the action of the upper return spring 5, the upper sliding gear 45 is reset and meshed with the upper fixed gear 44, so that the upper sliding gear 45 and the upper fixed gear 44 are locked, thereby ensuring the support and placement of the display device 7.

[0041] The upper gear body has an upper limit portion, which is extended in the direction away from the tooth portion; the upper limit portion is arranged in a conflicting manner with the support frame 3; in this way, the upper limit portion is used to limit the rotation of the upper sliding gear 45, thereby preventing the upper sliding gear 45 from rotating and affecting the engagement locking and separation unlocking.

[0042] The lower sliding gear 48 includes a lower gear seat and a lower gear body, the lower gear seat and the lower gear body are connected, and the lower gear body is engaged and locked or loosened and unlocked with the lower fixed gear 47; the adjustment structure 4 includes a lower return spring 6, one end of the lower return spring 6 is fixed, and the other end of the lower return spring 6 is connected to the lower gear seat, and the lower return spring 6 is used to apply a return elastic force to cause the lower fixed gear 47 and the lower gear body to be engaged and locked.

[0043] In this way, when the swing arm 46 swings due to the driving force, the swing arm 46 pulls the upper sliding gear 45 to move, and the upper sliding gear 45 overcomes the elastic force and is separated from the lower fixed gear 47, thereby adjusting the angle between the support frame 3 and the base 2, thereby adjusting the supporting height of the support frame 3, and then adjusting the placement height of the display device 7. After adjustment, the thrust is withdrawn, and under the action of the lower return spring 6, the lower sliding gear 48 is reset and meshed with the lower fixed gear 47, so that the lower sliding gear 48 and the lower fixed gear 47 are locked, ensuring the support and placement of the display device 7.

[0044] The lower gear body has a lower limit portion, which is extended in the direction away from the tooth portion; the lower limit portion is arranged in conflict with the support frame 3; in this way, the rotation of the lower sliding gear 48 is limited by the lower limit portion, avoiding the rotation of the lower sliding gear 48 and affecting the engagement locking and separation unlocking.

[0045] The adjustment structure 4 includes an arm fixed shaft 31, one end of the arm fixed shaft 31 is connected to the support frame 3, and the other end of the arm fixed shaft 31 passes through the middle of the swing arm 46, and the swing arm 46 and the arm fixed shaft 31 are movably arranged; under the action of the arm fixed shaft 31, the swing arm 46 is assembled on the support frame 3 to play a positioning role, so that the swing arm 46 is convenient for swinging under thrust, thereby realizing the driving of both ends of the swing arm 46.

[0046] The upper support 1 is a pallet component, which includes a pallet sheet and a bracket. The pallet sheet and the bracket are connected and arranged flatly and in contact with the display device 7. The bracket is used to support the display device 7, thereby realizing the placement and support of the display device 7.

[0047] Alternatively, the upper support seat 1 includes an upper support plate and a locking piece. The upper support plate is used to be arranged in a conflicting manner with the display device 7, and the locking piece is used to lock the upper support plate and the display device 7 to achieve the placement and support of the display device 7.

[0048] The base 2 includes a seat plate, which is arranged in a display configuration; in this way, the base 2 can be placed directly on a desktop or elsewhere to achieve placement of the bracket, thereby facilitating placement of the display device 7 .

[0049] Alternatively, the base 2 includes two clamping plates, which are hingedly arranged and used for clamping; in this way, the base 2 can be clamped on the edge of the table by the two clamping plates to achieve the setting of the bracket.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
