Detailed Description

The utility model is further elucidated below in conjunction with the accompanying drawings.

The orientations referred to in the present specification are all based on the orientations of the movable support of the present utility model when the movable support is in normal operation, and are not limited to the orientations during storage and transportation, but only represent relative positional relationships, and not absolute positional relationships.

Embodiment one:

The movable bracket comprises a door frame 1 and a roller 10 arranged at the bottom of the door frame 1, wherein a display bracket 2 is fixed above one side of the door frame 1, and a display is arranged on the display bracket 2; the display bracket 2 is a steel structure bracket in the prior art, and the steel structure bracket is fixed on the door frame 1 by bolts or welding. While the other side of the gantry 1, i.e. the side not mounting the display stand 2, is provided with a whiteboard stand 3 mounting a whiteboard 4, the whiteboard 4 being mounted on the whiteboard stand 3. The whiteboard bracket 3 is directly fixed on the portal 1, and when in use, the portal 1 is rotated to forward the back of the portal 1, thereby using the whiteboard 4.

In order to improve the functionality, the mast 1 comprises a bottom frame 11 at the bottom and a top frame 12 slidably mounted on the bottom frame 11, a second locking bolt 13 being arranged between the bottom frame 11 and the top frame 12; the display stand 2 is fixed to the top frame 12 and the whiteboard stand 3 is mounted to the bottom frame 11. The underframe 11 comprises two oppositely arranged inverted T-shaped legs, sliding legs are slidably arranged at two ends of each inverted T-shaped leg, a third locking bolt is arranged between each sliding leg and each inverted T-shaped leg, and a roller 10 is arranged at the outer side end part of each sliding leg.

Embodiment two:

The first embodiment has a certain defect that the heat dissipation effect of the display is poor because the display and the white board are arranged oppositely, so that the heat dissipation space on the back of the display is blocked; in addition, when the display and the whiteboard are required to be used simultaneously, it is inconvenient to turn the gantry 1 back and forth.

The present embodiment is modified from one working position to two working positions on the basis of the first embodiment. A first working position (shown in figure 1) which corresponds to the first working position of the first embodiment, wherein the whiteboard 4 is arranged vertically and is positioned on the back of the display with the writing surface facing away from the portal 1; and a second working position (shown in fig. 2), in which the whiteboard 4 is arranged vertically, the writing surface of the whiteboard 4 leaks out from the bottom of the display and is in the same direction as the screen of the display, the first working position is changed into the second working position, and the whiteboard 4 rotates 180 degrees.

As shown in fig. 1 and 2 together, the whiteboard bracket 3 includes a fixing frame 31 for fixedly mounting the whiteboard 4, the fixing frame 31 is rotatably mounted in the middle of the portal 1, and the whiteboard 4 is changed from the first working position to the second working position by rotating the fixing frame 31. A rotating hook 32 is arranged on one side of the whiteboard 4 far away from the hinge shaft, and the other end of the rotating hook 32 can be hooked on the top of the portal 1; when the rotating hook 32 is hooked on top of the mast 1, the whiteboard 4 is locked in position in the second operating position. When the swivel hook 32 releases the door frame 1, the whiteboard 4 is flipped downwards and can be shifted to the second working position.

The first working position is the same as the first working position, and the writing surface of the whiteboard 4 is positioned below the display in the second working position, so that the whiteboard can be used simultaneously when the display is used.

Embodiment III:

In the second embodiment, there is a certain defect, and when the whiteboard 4 is used in the second working position, because there is no limit, the whiteboard 4 needs to be held, otherwise, the whiteboard 4 is easy to shake, so the embodiment is further improved on the basis of the second embodiment, and the limit structure 34 is added.

As shown in fig. 4, the mounting seats 33 are symmetrically arranged on both sides of the portal 1, the mounting seats 33 are provided with mounting holes 331, the two ends of the fixing frame 31 are provided with rotating shafts 311, the rotating shafts 311 are inserted into and rotatably mounted in the mounting holes 331 on the corresponding sides, and a limiting structure 34 is arranged between the rotating shafts 311 and the mounting holes 331.

The limiting structure 34 comprises limiting grooves 342 arranged at the outer side end part of the rotating shaft 311, and at least two limiting grooves 342 are arranged; since two working positions are set in the present embodiment, two limiting grooves 342 are provided in the present embodiment, and the two limiting grooves 342 are set corresponding to the first working position and the second working position. When changing from the first working position to the second working position, the whiteboard 4 rotates 180 °, so the two limit grooves 342 are symmetrically arranged centering on the axis of the rotation shaft 311. In practical application, the number of the limiting grooves 342 may be four, as long as any two of the limiting grooves 342 are symmetrically arranged with the axis of the rotating shaft 311 as the center.

The installation hole 331 is internally provided with an elastic pin 343 which can be stretched and contracted but cannot rotate, and a matched chute and a limiting protrusion (not shown in the figure) are arranged between the installation hole 331 and the elastic pin 343, so that the elastic pin 343 can be controlled to stretch and contract only in the installation hole 331 but cannot rotate. The inside end of the elastic pin 343 is provided with a positioning head 344 inserted into the limit grooves 342, and when two limit grooves 342 are provided, the whiteboard 4 is in a vertical state after the elastic pin 343 is inserted into any one of the limit grooves 342. In this embodiment, when two limiting grooves 34 are provided, a linear groove may be formed, and the corresponding positioning head 344 may also be a linear head.

A return spring 341 is clamped between the elastic pin 343 and the mounting seat 33, and a positioning head 344 of the elastic pin 343 is inserted into the limiting groove 342 under the action of the return spring 341, so that position locking is realized.

Embodiment four:

As shown in fig. 3, 5 and 6 together, this embodiment adds a working position (as shown in fig. 3) on the basis of the third embodiment, and when the mounting base 33 slides to the bottommost part of the gantry 1 in this working position, the whiteboard 4 is horizontally disposed.

As shown in fig. 3, the mounting seat 33 is mounted on the door frame 1 in a vertically sliding manner, a sliding groove for sliding the mounting seat 33 is formed in the door frame 1, and a first locking bolt 35 is arranged between the mounting seat 33 and the door frame 1; when the mounting seat 33 slides to the bottommost part of the portal 1, the whiteboard 4 is horizontally arranged, that is, the whiteboard 4 hovers horizontally, which is the third working position (as shown in fig. 3); meanwhile, the limit groove 342 corresponding to the third working position is provided on the limit groove 342, and the whiteboard 4 needs to rotate 90 ° when changing from the first working position to the third working position, so that the limit groove 342 is 90 ° with the other two limit grooves 342. For easy manufacture and installation, four limiting grooves 342 are provided, and four limiting grooves 342 are arranged in a circumferential array with the axis of the rotating shaft 311 as the center. For convenience, the four limiting grooves 342 form a cross-shaped groove, and the positioning head 344 can still adopt the shape of the above straight line, or can adopt a cross shape, so that the whiteboard 4 has four working positions theoretically, but only three working positions are used because of the limitation of the portal 1.

In order to increase the supporting strength, the swivel hook 32 can be used here as a supporting leg, when the whiteboard 4 is in the third working position, the swivel hook 32 can be turned down and then supported on the ground. In this case, the whiteboard 4 can be used as a rack.

The movable bracket solves the technical problems that in the prior art, the support functionality of the movable bracket is low, and the display and the whiteboard can not be supported simultaneously.
