Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, fig. 1 and 2 show an embodiment of the present invention, the integrated machine includes a base, two sides of the base are rotatably connected with lower ends of parallelogram linkages, respectively, and upper ends of the parallelogram linkages are connected with two sides of an upper rotating shaft support 18, respectively, and a front surface of the upper rotating shaft support 18 is fixedly connected with a display screen (not shown).
Referring to fig. 2, the parallelogram four-bar linkage mechanism is composed of an upper link 3, a first link 5, a second link 6 and a lower link 8, is arranged in the inner cavity of the bracket side arm 4, and is sealed by a link cover plate 1. When a certain force is applied to the bracket side arm 4, the bracket side arm 4 rotates around the lower fixed shaft 7, so that the first connecting rod 5 and the second connecting rod 6 are driven to rotate for a certain angle; the characteristics of the parallelogram link structure enable the first link 5 and the second link 6 to drive the upper link 3 to synchronously rotate by corresponding angles, and simultaneously the upper fixed shaft 2 drives the display screen to correspondingly rotate. The upper connecting rod 3 drives the integrated machine to rotate correspondingly by virtue of the axial friction force provided by the resistance adjusting elastic sheet 13, and the rotating radius of the two upper fixed points is equal to that of the two lower connecting rods 8, so that the upper connecting rod 3 can compensate for the same angle after the lower connecting rods 8 rotate for a certain angle, and the angle between the display screen and the desktop can be kept unchanged.
On the basis of the above, the present embodiment is further provided with a secondary rotating mechanism, which includes the upper fixed shaft 2 and the matching holes on both sides of the upper rotating shaft support 18; one end of the outer side of the upper fixed shaft 2 is vertically and fixedly connected with the rod body of the upper connecting rod 3, and the other end of the upper fixed shaft penetrates through matching holes on the bending plates at two sides of the upper rotary shaft support 2 and is rotatably connected with the upper rotary shaft support.
Further, referring to fig. 2, an upper limit baffle 12 is further arranged on the shaft body of the upper fixing shaft 2 passing through the matching hole; the bending plates on the two sides of the upper rotary shaft support 18 are provided with arc grooves, and the upper limiting blocking pieces 12 extend into the arc grooves and slide in the limited range. Referring to fig. 3-5, since the matching holes of the upper rotating shaft support 18 and the upper fixed shaft 2 are round holes, the upper rotating shaft support 18 can freely rotate within a limit angle, so as not to be limited by the rotation angle of the parallelogram link, i.e. the secondary rotating mechanism can independently operate, and a structure which can flexibly rotate and be used is added.
Similarly, an arc-shaped limiting mechanism groove matched with each other is also formed between the lower limiting baffle 16 and the side arm 4 of the bracket, so that the lower connecting rod 3 is ensured to rotate in a specific angle, and the use safety is ensured.
Further, an upper torsion spring 15 for adjusting the torque of the upper fixing shaft 2 is arranged on the shaft body of the upper fixing shaft, and the torque of the upper torsion spring 15 is different when the display screen rotates to different angles. When the display screen is in a vertical state, the gravity moment is maximum, the torsion moment of the upper torsion spring 15 is also maximum, and the gravity moment and the torsion moment are mutually offset, so that the pitching rotation force of the display screen is relatively balanced, and better user experience is achieved.
In the same way, the torsion moment of the lower fixed shaft 7 is different when the lower torsion spring 9 rotates at different angles on the side wall 4 of the bracket, so that the gravity moment of the integrated machine can be offset, and the labor is saved when the display screen is lifted.
In addition, a locking nut 14 is provided, the locking nut 14 is sleeved on the shaft body of the upper fixed shaft 2 and presses one side of the resistance adjusting elastic sheet 13, and the other side of the resistance adjusting elastic sheet 13 presses the adjusting plate on the upper fixed shaft 2 and generates resistance. Similarly, the lower fixing shaft 7 is provided with a lower locking nut 11 and a lower resistance adjusting sheet 10. In this embodiment, the force of the resistance adjusting piece 10 can be adjusted by tightening or loosening the lock nut 11, so that the force of the rotation of the rotating shaft of the lower link 3 is adjusted by the resultant force of the resistance and the torsion spring.
Preferably, the upper rotating shaft support 18 is fixedly connected with the display screen through the adapter plate 17, and the adapter plate 17 can ensure that the upper rotating shaft support 18 can be used for installing display screens with different sizes and specifications, so that the applicability is wider.
The embodiments of the present invention have been described in conjunction with the accompanying drawings and examples, the structures of which are not intended to limit the present invention, and those skilled in the art can make modifications as required, and all changes and modifications within the scope of the appended claims are within the scope of protection.
