[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0030] The top surface of the base 1 is provided with a rotating disk 2, and the top surface of the rotating disk 2 is provided with a supporting column 3, and two brackets 31 are fixed in parallel on the top surface of the supporting column 3. An internal threaded sleeve 32 is rotatably connected between the two brackets 31, and a threaded rod 33 is internally threadedly connected to the internal threaded sleeve 32. An extension plate 30 is fixed to the middle part of the side surface of the supporting column 3 close to the threaded rod 33, and a mounting plate 4 is hinged on the other end of the extension plate 30. The movable end of the threaded rod 33 is slidably connected to the mounting plate 4 through a trapezoidal block 41. A trapezoidal groove 40 corresponding to the position of the trapezoidal block 41 and matching the size is provided in the middle part of the side surface of the mounting plate 4 close to the threaded rod 33. A display screen body 5 is fixed to the side of the mounting plate 4 away from the supporting column 3. A limiting mechanism 6 is also installed on the top surface of the base 1 to prevent the internal threaded sleeve 32 from rotating. The rotating disk 2 can be rotated to adjust the deflection angle of the display screen body 5, and the internal threaded sleeve 32 can be rotated to deflect the display screen body 5 up and down. Multi-angle adjustment can meet more needs.

[0031] In this embodiment, two vertical plates 10 are fixed opposite to each other at the top surface of the base 1 near the bottom end of the outer wall of the turntable 2. The vertical plates 10 are equipped with bolts 11. The bolts 11 pass through the threaded holes on the vertical plates 10 on the same side and abut against the turntable 2. After the turntable 2 is rotated, the bolts 11 are used to prevent the turntable 2 from rotating, thereby improving the stability of the display screen body 5.

[0032] Specifically, a shift block 20 is regularly fixed at the top of the outer side wall of the turntable 2 , and the position of the shift block 20 is higher than the position of the vertical plate 10 , so that it is convenient to shift the shift block 20 and thus control the rotation of the turntable 2 .

[0033] Furthermore, the threaded rod 33 is hinged to the trapezoidal block 41, the end of the extension plate 30 away from the support column 3 is hinged to the bottom end of the mounting plate 4, and a handwheel 34 is fixed to the end of the internal threaded sleeve 32 away from the threaded rod 33, so as to conveniently control the rotation of the internal threaded sleeve 32 through the handwheel 34.

[0034] In addition, the limiting mechanism 6 includes two fixing plates 60 fixed to the top surface of the support column 3, the two fixing plates 60 are located on both sides of the internal threaded sleeve 32, and two clamping blocks 62 for preventing the internal threaded sleeve 32 from rotating are arranged between the two fixing plates 60. The clamping blocks 62 can cooperate with each other to prevent the internal threaded sleeve 32 from rotating.

[0035] It is worth mentioning that fixed columns 61 that penetrate the two clamping blocks 62 are fixed between the four corners of the opposite surfaces of the two fixed plates 60, and a spring 63 that is sleeved outside the fixed column 61 is installed between the clamping block 62 and the fixed plate 60 on the same side. The fixed column 61 guides the movement of the clamping block 62, and the spring 63 enables the two clamping blocks 62 to approach each other and clamp the internal threaded sleeve 32.

[0036] It is worth noting that the opposing surfaces of the two clamping blocks 62 are provided with arc grooves that are adapted to the size of the internally threaded sleeve 32, and the clamping blocks 62 are adhered with anti-skid pads 64 in the arc grooves that fit tightly with the outer wall of the internally threaded sleeve 32. The anti-skid pads 64 can increase the friction, improve the clamping effect of the clamping blocks 62, and prevent the internally threaded sleeve 32 from rotating.

[0037] When the angle-adjustable display screen of the utility model is used, when the angle of the display screen body 5 needs to be controlled, the two bolts 11 are rotated, the bolts 11 do not abut against the turntable 2, the dial block 20 is moved to rotate the turntable 2 to a suitable position, and then the bolts 11 are rotated in the opposite direction, the bolts 11 abut against the turntable 2 again, and the turntable 2 is prevented from rotating;

[0038] The two clamping blocks 62 are then moved by hand to move the two clamping blocks 62 away from each other, the spring 63 is compressed, and then the hand wheel 34 is turned, the movable end of the threaded rod 33 moves outward and pushes the trapezoidal block 41 to rise, and the mounting plate 4 and the display screen body 5 deflect downward, and the hand wheel 34 is turned in the opposite direction, and the mounting plate 4 and the display screen body 5 will deflect upward; the two clamping blocks 62 are released, and the spring 63 drives the two clamping blocks 62 to approach each other, and the clamping blocks 62 slide on the fixing column 61 and clamp the internal threaded sleeve 32, and the two anti-skid pads 64 fit tightly with the internal threaded sleeve 32 to prevent the internal threaded sleeve 32 from rotating; the display screen body 5 can be adjusted in two directions, which is more practical; because the bottom end of the mounting plate 4 is hinged to the extension plate 30, the mounting plate 4 can only deflect around the hinge of the extension plate 30, and after the mounting plate 4 is adjusted, the internal threaded sleeve 32 is clamped and fixed by the two clamping blocks 62, so that the positions of the internal threaded sleeve 32 and the threaded rod 33 are fixed, and the mounting plate 4 is in a stable state.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
