Detailed Description

The present invention will be described in detail with reference to the drawings, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-4, an angle-adjustable whiteboard device includes a bracket 1 and a whiteboard 2, wherein the whiteboard 2 is mounted on the bracket 1 through an angle-adjustable adjusting mechanism 3; adjustment mechanism 3 includes frame 31, axis of rotation 32 to and at least two sets of coupling assembling 33, but whiteboard 2 passes through axis of rotation 32 horizontal rotation and installs in frame 31, frame 31 passes through coupling assembling 33 and can overturn from top to bottom and install on support 1.

As shown in fig. 3, the connecting assembly 33 includes a connecting member 331 fixedly mounted on the outer side of the frame 31, a shaft sleeve 332 is connected to the outer side of the connecting member 331, a shaft 333 is sleeved in the shaft sleeve 332, and the shaft 333 is fixedly mounted on the bracket 1; at least one threaded hole is radially opened in the circumference outside of connecting piece 331, fastening screw 334 is installed through the threaded hole matching in connecting piece 331, fastening screw 334's one end is contradicted in the surface of axle sleeve 332. Preferably, a rubber bushing is arranged in the shaft sleeve 332, so that on one hand, the friction force between the shaft sleeve 332 and the shaft 333 is increased by utilizing the characteristic of large friction coefficient of rubber, resistance is generated on the rotation of the connecting piece 331 and the shaft sleeve 332, and meanwhile, the rotation of the frame 31 can be ensured, so that the frame 31 can hover at the current angle when no external force is applied, and the frame 31 and the whiteboard 2 can rotate when an external force capable of overcoming the friction force is applied, thereby realizing the adjustment of the vertical turning angle of the whiteboard 2. The whiteboard is adjusted to an angle suitable for the user to write, or the whiteboard is adjusted to an angle reducing the reflection of light.

Preferably, one end of the connecting piece 331 is provided with a groove, one end of the shaft sleeve 332 is embedded in the groove of the connecting piece 331, shaft sleeve threaded holes are radially formed in the shaft sleeve 332, the shaft sleeve threaded holes correspond to the threaded holes in the connecting piece 331 one by one, the fastening screws 334 correspond to the threaded holes in the connecting piece 331 and the shaft sleeve threaded holes one by one, and the fastening screws 334 are inserted into the corresponding threaded holes; when the whiteboard 2 needs to be turned over up and down to adjust the angle, the frame 31 is movably connected with the bracket 1, the frame 31 rotates relative to the bracket 1, the connecting piece 331 is tightly matched with the shaft sleeve 332, or the connecting piece 331 is linked with the shaft sleeve 332 through the fixing function of the fastening screw 334, and the frame 31 rotates around the shaft 333. Because the one end of fastening screw 334 is contradicted at the surface of the interior rubber bush of axle sleeve 332, produce the squeezing action to the rubber bush, force to produce frictional force between axle sleeve 332 and the axle 333, further produce the resistance to the rotation of connecting piece 331 and axle sleeve 332, make the frame 31 when not exerting external force on the one hand, can hover at present angle, on the other hand has played the firm effect, prevent that too big frame 31 of exerting oneself from driving whiteboard 2 to rotate when writing on whiteboard 2, inconvenient writing, but when exerting the external force that can overcome this frictional force, can be rotatory with frame 31 and whiteboard 2.

In this embodiment, the number of the fastening screws 334 is two, and in practical applications, the number of the fastening screws 334 can be adjusted as required, and in addition, one end of the fastening screw 334 is preferably a tail end, i.e. a head end for tightening is disposed outside the connecting member 331, and a top end of the tail end opposite to the head end abuts against an outer surface of the rubber bushing in the sleeve 332.

Further, the utility model discloses in, axis of rotation 32 symmetry sets up in two inboard upper and lower borders of

frame

31, 32 one end of axis of rotation and 2 fixed connection on the blank, the other end is connected through installing the antifriction bearing on frame 31. The number of the rotating shafts 32 is two, and the two rotating shafts are symmetrically arranged at the upper edge and the lower edge of the inner side of the frame 31. An external force is applied to one side of the whiteboard 2, and the whiteboard 2 can rotate left and right or turn over around the rotating shaft 32; when 2 reflection of light influences reading of blank, can be with the nimble slope that rotates that carries on of blank 2 to the left and right sides, suitable angle of adjustment avoids the reflection of light face, and the people of both sides (for the both sides in 2 dead ahead of blank) read in the convenience of classroom or meeting room, perhaps can overturn to the another side when the one side explanation finishes and continue the explanation, need not unnecessary operation can easily overturn blank 2 when using, and the operation is very simple and convenient.

Preferably, as shown in fig. 4, a fixing frame 4 is installed on the frame 31, the fixing frame 4 includes a bolt 42 and a U-shaped plate 41 adapted to the thickness of the frame 31, the U-shaped plate 41 is clamped on one side of the frame 31, a frame threaded hole is formed in one side of the frame 31, and the bolt 42 is inserted into the center of the U-shaped plate 41 and is matched with the frame threaded hole in the frame 31; when the whiteboard 2 needs to be fixed, the bolt 42 is matched with the threaded hole of the frame, the fixing frame 4 positioned on one side of the whiteboard 2 moves towards the whiteboard 2, and one side of the whiteboard 2 is positioned in the U-shaped cavity of the U-shaped plate 41 and clamped, so that the whiteboard 2 is prevented from rotating left and right when a user writes, and the user writes conveniently; when the whiteboard 2 needs to rotate left and right, the bolts 42 are unscrewed in the opposite direction, so that the fixing frame 4 is separated from the whiteboard 2, the U-shaped opening of the U-shaped plate 41 is positioned at the outer side of the whiteboard 2, and the whiteboard 2 can rotate by rotating the whiteboard 2 at the moment. Further, a clamping ring 43 is arranged on the bolt 42, and a clamping groove matched with the clamping ring 43 is arranged in the U-shaped plate 41; so that the bolt 42 is matched with the frame threaded hole on the frame 31, when the bolt 42 moves, the U-shaped plate 41 is connected with the bolt 42 into a whole through the snap ring 43 on the bolt 42, and at the moment, the fixing frame 4 also moves along with the bolt.
