Abstract
The invention provides a display support and an automatic adjusting rod thereof. The automatic adjusting rod comprises a safety sleeve, a piston rod and an automatic force adjusting valve. When the movable plate is pulled, the safety sleeve in the automatic adjusting rod can rotate along with the movable plate, and the piston rod penetrates through the safety sleeve, and the insertion part of the safety sleeve is tightly pushed outwards and opened through the force automatic adjusting valve, so that the friction force between the safety sleeve and the piston rod is large although the safety sleeve can rotate, and when the display is inclined at a certain angle, the safety sleeve and the piston rod cannot rotate relatively. When the display of bigger weight or required inclination is bigger need be connected to the activity plate, only need further tighten dynamics automatically regulated valve, and then with the inserting part of piston rod further outwards open can. Therefore, the bracket of the invention can bear a display with larger weight and has no problems of sliding teeth and the like.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 and 2, a display stand according to a preferred embodiment of the present invention includes a fixed plate 10, a movable plate 20, and an automatic adjustment rod 30. Referring to fig. 3 to 5, the automatic adjustment rod 30 includes a safety sleeve 1, a piston rod 2 and an automatic force adjustment valve 3.
Referring to fig. 6 and 7, the piston rod 2 has a connecting portion 21 at one end and an insertion portion 22 at the other end. Referring to fig. 8 and 9, the safety sleeve 1 has a connecting portion 11 at one end and a sleeve portion 12 at the other end. The insertion part 22 of the piston rod 2 is hollow and cylindrical, an internal thread is arranged in the insertion part 22, and two opposite telescopic openings 221 are formed in the insertion part 22 along the axial direction of the insertion part. The insertion portion 22 is inserted into the sleeve portion 12 of the safety sleeve 1.
Referring to fig. 10 and 11, the force automatic regulating valve 3 has a conical top opening portion 32, and two ends of the conical top opening portion 32 are a connecting end 31 and a screwing end 33, respectively. The connecting end 31 and the tapered open top portion 32 are provided with external threads on their peripheries, and the connecting end 31 and the tapered open top portion 32 extend into the insertion portion 22 of the piston rod 2 and are connected with the internal threads of the insertion portion 22.
Preferably, the outer periphery of the screwing end 33 is provided with a plurality of corners 331, and in this embodiment, the cross section of the screwing end 33 is regular hexagon.
One side of the safety sleeve 1 close to the connecting part 11 is further provided with a containing hole 13, and the containing hole 13 is communicated with the inner space of the sleeve part 12. After the connecting end 31 and the conical top opening part 32 of the automatic force adjusting valve 3 are screwed into the inserting part 22, the screwing end 33 is positioned in the accommodating hole 13. When the safety sleeve 1 rotates, the edge 331 of the twisting end 33 can generate spatial interference with the hole wall of the accommodating hole 13, thereby preventing the safety sleeve 1 from continuing to rotate.
Furthermore, an annular hydraulic cylinder 222 is further disposed on an outer peripheral edge of the insertion portion 22 of the piston rod 2, solid oil is filled in the annular hydraulic cylinder 22, and after the insertion portion 22 is inserted into the sleeve portion 12 of the safety sleeve 1, an inner wall of the sleeve portion 12 wraps an opening of the annular hydraulic cylinder 222, so that the solid oil is prevented from leaking outside. The solid oil in the annular hydraulic cylinder 222 can be pressed against the interior of the sleeve part 12, so that the friction force between the insertion part 22 and the sleeve part 12 is increased, and the bearing capacity of the support is improved, meanwhile, the solid oil can be deformed by extrusion, namely, the gap between the outer periphery of the insertion part 22 and the inner wall of the sleeve part 12 can be finely adjusted, and therefore, the relative rotation angle between the movable plate 20 and the fixed plate 10 has a rough adjustment process and a fine adjustment process, so that the adjusted support is more stable, a display with large weight can be borne, and the movable plate 20 and the fixed plate 10 are effectively prevented from being accidentally rotated relatively.
The connecting portion 21 of the piston rod 2 is provided with a mounting hole 211 along the longitudinal direction thereof, and the connecting portion 11 of the safety sleeve 1 is provided with a mounting hole 111 along the longitudinal direction thereof. The connecting part 21 of the piston rod 2 is connected with the fixed plate 10, and the connecting part 11 of the safety sleeve 1 is connected with the movable plate 20. That is, the automatic adjusting lever 30 is installed between the movable plate 20 and the fixed plate 10 of the stand, thereby realizing the function of turning adjustment of the stand (adjustment of the inclination angle of the display).
When the movable plate 20 is pulled, the safety sleeve 1 in the automatic adjusting rod 30 rotates along with the movable plate 20, and because the piston rod 2 is inserted into the safety sleeve 1, the insertion portion 22 of the safety sleeve is pushed outwards and opened by the force automatic adjusting valve 3, the friction between the safety sleeve 1 and the piston rod 2 is large although the safety sleeve 1 can rotate, and when the movable plate 20 stops at a certain position (i.e. when the display is inclined at a certain angle), the safety sleeve 1 and the piston rod 2 cannot rotate relatively. When the movable plate 20 needs to be connected with a display with larger weight or needs a larger inclination angle, the force automatic adjusting valve 3 is further screwed, and the insertion part 22 of the piston rod 2 is further opened outwards. Therefore, the bracket of the embodiment can bear a display with larger weight, and has no problems of sliding teeth and the like.
Meanwhile, when the angle of the display is adjusted, only the movable plate 20 needs to be pulled, and additional fastening parts do not need to be screwed, so that the adjusting process is convenient.
In addition, because dynamics automatically regulated valve 3 twists end 33 and has edges and corners 331, when the pore wall that rotates its holding hole 13 in-process in insurance sleeve 1 and edges and corners 331 take place the space and interfere, dynamics automatically regulated valve 3 can be driven and rotate certain angle, promptly, insertion part 22 can be to opening a certain limit to realize the dynamics regulatory function of certain limit. When the display device is rotated to a certain range, the friction force between the insertion portion 22 and the sleeve portion 1 is increased, the edge 331 limits the safety sleeve 1 to rotate further, so that the display device can be prevented from inclining to a larger angle, and a safety function is achieved, so that the display device can stably maintain a required inclination angle.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
