Description

Technical Field

[0001] The utility model belongs to the technical field of display screen brackets, in particular to a display screen mobile control bracket. Background Art

[0002] There are more and more types and uses of monitors.

[0023] like Figure 2 and Figure 5 As shown, the operating frame 4 includes a linkage pressure plate 41 arranged at the bottom of the base 1, and the bottom of the linkage pressure plate 41 is fixedly connected with two left and right sliding rods 42, and the sliding rods 42 are sleeved inside the base 1. The upper ends of the two sliding rods 42 extend to the top of the base 1 and are fixedly connected with a linkage frame 43, and the top of the linkage frame 43 is rotatably clamped with a locking knob 44; wherein the linkage pressure plate 41 is composed of two front and rear snap-fit ​​plates, and the two snap-fit ​​plates are fixedly connected by bolts, and the two fixedly connected snap-fit ​​plates can be fixedly sleeved with the second bearing 28.

[0024] like Figure 1 and Figure 5 As shown, the adapter rod 5 includes a limiting rod 51 that is movably arranged in the middle of the linkage frame 43 and the locking knob 44. The upper end of the limiting rod 51 passes through the locking knob 44 and is fixedly connected with an anti-slip block 53. The lower end of the limiting rod 51 passes through the linkage frame 43 and is fixedly connected to the top of the base 1. The outer surface of the limiting rod 51 is provided with a locking thread 52 located below the linkage frame 43. Due to the provision of the anti-slip block 53, the operating frame 4 can be prevented from separating from the limiting rod 51, and then the locking knob 44 and the linkage frame 43 can slide up and down along their surfaces with the cooperation of the limiting rod 51, and the connection between the locking knob 44 and the locking thread 52 can be conveniently moved, thereby fixing the operating frame 4.

[0025] like Figure 5 As shown, the outer diameter of the locking thread 52 is smaller than the inner diameter of the linkage frame 43 , the inner wall of the locking knob 44 is matched with the locking thread 52 , and the locking knob 44 is fixedly connected to the limiting rod 51 via the locking thread 52 .

[0026] like Figure 3 and Figure 4As shown, the brake universal wheel 2 includes a second bearing 28 fixedly clamped in the interior of the linkage pressure plate 41, the interior of the second bearing 28 is fixedly sleeved with the connecting shaft 21, the interior of the connecting shaft 21 is movably sleeved with the brake assembly 22, the lower end of the brake assembly 22 passes through the connecting shaft 21 and is connected to the mounting frame A23, and the lower end of the mounting frame A23 is movably connected to the wheel 24; due to the setting of the second bearing 28, it can be ensured that when the linkage pressure plate 41 moves up and down, it can drive the pressure block 224 to move up and down, and then slowly press the brake pad 227 with the cooperation of the reset spring 226, so as to achieve the braking effect; at the same time, it can be ensured that the rotation of the brake universal wheel 2 will not be affected by the operating frame 4.

[0027] like Figure 4 As shown, a positioning shaft 25 is fixedly sleeved in the middle of the wheel 24, and both ends of the positioning shaft 25 pass through the wheel 24 and extend to the outside of the mounting frame A23 and are fixedly connected with a positioning gear 26, and both ends of the positioning shaft 25 are movably sleeved in the interior of the mounting frame A23; a positioning tooth plate 27 is arranged above the positioning gear 26, and the bottom of the positioning tooth plate 27 is meshed and connected with the top of the positioning gear 26, and the upper end of the positioning tooth plate 27 is fixedly connected with the connecting shaft 21; due to the setting of the positioning tooth plate 27, after the brake stops, the locking knob 44 is rotated downward, so that the bottom of the positioning tooth plate 27 can be tightly abutted against the positioning gear 26, so that the wheel 24 can be completely locked so that it cannot rotate, thereby achieving the effect of parking.

[0028] like Figure 4 As shown, the brake assembly 22 includes a connecting sleeve 221 movably sleeved inside the connecting shaft 21, the top of the connecting sleeve 221 passes through the connecting shaft 21 and is rotatably clamped on the bottom of the base 1, the interior of the connecting sleeve 221 is sleeved with a first bearing 222 and a pressure block 224, the first bearing 222 is fixedly sleeved on the bottom of the inner cavity of the connecting sleeve 221, the upper end of the pressure block 224 is located above the first bearing 222 and movably sleeved inside the connecting sleeve 221, the lower end of the pressure block 224 passes through the first bearing 222 and extends to the interior of the mounting frame A23 and is fixedly connected with a brake pad 227, and the bottom of the brake pad 227 is in contact with the bottom of the wheel 24.

[0029] like Figure 4 As shown, the outer surface of the connecting sleeve 221 is provided with a slide groove 223 located on the outer side of the pressure block 224, and a slider 225 is slidably engaged inside the slide groove 223. One side of the slider 225 extends to the inside of the connecting sleeve 221 and is fixedly connected to the upper end of the outer surface of the pressure block 224, and the other side of the slider 225 extends to the outside of the connecting sleeve 221 and is fixedly connected to the inside of the connecting shaft 21. Due to the setting of the slide groove 223, when the linkage pressure plate 41 moves up and down with the cooperation of the slider 225, the pressure block 224 can be driven to move downward through the second bearing 28 and the connecting shaft 21, thereby pushing the brake pad 227 to move downward to achieve a braking effect.

[0030] A return spring 226 is disposed inside the connecting sleeve 221 and is located at the top of the first bearing 222 . The lower end of the return spring 226 abuts against the top of the outer ring of the first bearing 222 , and the upper end of the return spring 226 abuts against the upper end of the pressing block 224 .

[0031] The working principle and use process of this utility model:

[0032] The display is fixed to the upper end of the support frame 6 by the mounting frame B7, and then the support frame 6 is pushed with the cooperation of the brake universal wheel 2 and the universal wheel 3 to move the display with the cooperation of the operating frame 4. During the movement, the locking knob 44 is pressed down to push the linkage pressure plate 41 downward through the linkage frame 43 and the slide rod 42. The movement of the linkage pressure plate 41 can drive the slider 225 to slide downward along the inside of the slide groove 223 through the connecting shaft 21 under the cooperation of the second bearing 28, and then drive the pressure block 224 to slide downward along the inside of the connecting sleeve 221, pushing the brake pad 227 downward and compressing the return spring 226 under the cooperation of the outer ring of the first bearing 222. The downward movement of the brake pad 227 can resist the wheel 24, increase its rotation resistance, and thus achieve the purpose of braking.

[0033] When braking to a complete stop, press down the locking knob 44 to make the brake pad 227 fit tightly against the wheel 24, and at the same time ensure that the lower end of the locking knob 44 contacts the locking thread 52, and then rotate the locking knob 44 to connect it with the locking thread 52. Continuing to rotate the locking knob 44 can make the operating frame 4 continue to move downward until the lower end of the positioning tooth plate 27 at the bottom of the connecting shaft 21 is tightly meshed with the top of the positioning gear 26. At this time, with the cooperation of the locking thread 52, the operating frame 4 can be kept fixed, thereby ensuring a complete brake stop.
