Technical Field
[0001] The utility model relates to the technical field of support frames, in particular to a mobile whiteboard support capable of both angle rotation and self-locking. Background Art
[0002] Whiteboard stands are used to install and support whiteboards. They are mainly used in mobile multimedia teaching, multimedia conference rooms in enterprises and institutions, etc., so that whiteboards can be placed firmly and used conveniently. Whiteboard stands usually have an adjustable function, which can adjust the angle of the whiteboard as needed to meet the needs of different users.
[0003] There are two common ways to lock the angle of the bracket: 1. Mechanical locking: The angle of the whiteboard is fixed through the mechanical structure on the bracket, such as buckles, knobs or bolts. This method is relatively simple to operate and has a stable locking effect, but manual adjustment or tools may be required during adjustment, and the adjustment is relatively stable; 2. Friction locking: The friction between the bracket and the whiteboard is used to lock the angle of the whiteboard. This method usually does not require additional tools and is more convenient to adjust, but the locking effect may be affected by factors such as the weight of the whiteboard and the use environment, and the locking is not stable enough.
[0004] Therefore, it is necessary to propose a mobile whiteboard bracket that takes into account both angle rotation and self-locking to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0026] See also Figure 1-4 As shown, a mobile whiteboard bracket that takes into account both angle rotation and self-locking, includes a base 15, a column 2 is fixedly connected to the base 15, a crossbeam 5 is fixedly connected to the top of the column 2, a rotating frame 4 and a support frame 6 are provided on one side of the column 2, the rotating frame 4, the support frame 6 and the column 2 form a triangular support structure, the two ends of the rotating frame 4 are respectively hinged to the crossbeam 5 and the support frame 6, the rotating frame 4 is connected to the column 2 through a self-locking member 10, and the self-locking member 10 is used to lock the inclination angle of the rotating frame 4; the self-locking member 10 includes an anti-sliding block 11, a connecting rod 12 and a sliding frame 13 that slides along the column 2, the two ends of the connecting rod 12 are respectively hinged to the support frame 6 and the sliding frame 13, the anti-sliding block 11 is fixedly connected to the side of the connecting rod 12 close to the column 2, and a torsion spring 16 for driving the anti-sliding block 11 to rotate toward the column 2 is provided at the hinge between the connecting rod 12 and the sliding frame 13.
[0027] The whiteboard 1 is supported by a triangular support structure formed by the rotating frame 4, the support frame 6 and the column 2, and the support is more stable. The inclination angle of the rotating frame 4 can be adjusted by sliding the end of the support frame 6 along the column 2. When the support frame 6 is perpendicular to the column 2, the rotating frame 4 reaches the minimum inclination angle;
[0028] When the support frame 6 needs to be moved upward along the column 2, the rotating frame 4 is rotated upward, and the connecting rod 12 is driven by the supporting frame 6 to rotate in a direction away from the column 2 under the traction of the rotating frame 4, so that the anti-sliding block 11 is away from the column 2, and the sliding frame 13 slides upward along the column 2, thereby realizing the upward movement of the support frame 6. When the rotating frame 4 is released, the anti-sliding block 11 is reset under the action of the torsion spring 16;
[0029] When it is necessary to move the support frame 6 downward along the column 2, Figure 3 Pull the support frame 6 in the direction of the middle arrow F. Under the action of the pulling force, the support frame 6 drives the connecting rod 12 to rotate in the direction away from the column 2, so that the anti-sliding block 11 is away from the column 2, and the sliding frame 13 slides downward along the column 2, thereby realizing the downward movement of the support frame 6. When the support frame 6 is released, the anti-sliding block 11 is reset under the action of the torsion spring 16.
[0030] Specifically, in order to make the support more stable, the support frame 6 is located above the self-locking member 10, and the angle between the connecting rod 12 and the sliding frame 13 is less than 90°.
[0031] When pressure is applied to the rotating frame 4, the pressure is transmitted to the connecting rod 12 through the supporting frame 6, and the connecting rod 12 drives the anti-sliding block 11 to move toward the column 2, thereby increasing the friction between the column 2 and the anti-sliding block 11 to prevent the two from sliding relative to each other.
[0032] In some embodiments, the sliding frame 13 is slidably connected to the column 2 via a pulley 14, and there are two pulleys 14, which are symmetrically distributed on both sides of the column 2. Specifically, a limiting groove is provided in the middle of the pulley 14 to match the column 2. Under the action of the limiting groove, the lifting and lowering of the sliding frame 13 is more stable.
[0033] In some embodiments, in order to facilitate the positioning of the whiteboard 1, the end of the rotating frame 4 close to the supporting frame 6 is fixedly connected to the lower supporting plate 9. Both ends of the crossbeam 5 are slidably connected to the sliding rod 7 along its length direction, and the end of the sliding rod 7 away from the crossbeam 5 is fixedly connected to the side baffle 8, and the two sliding rods 7 are connected by a tension spring.
[0034] The bottom end of the whiteboard 1 can be supported by the lower supporting plate 9, and the two sides of the whiteboard 1 can be limited by the side baffles 8. At the same time, under the action of the tension spring, the two side baffles 8 can clamp and fix the whiteboard 1.
[0035] In some embodiments, in order to facilitate the movement of the bracket, self-locking universal wheels 3 are fixedly connected to the four corners of the bottom end of the base 15.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
