[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0036] like Figure 1-11 As shown, a movable electronic whiteboard includes a base 101, a gas spring 102, casters 105, and a display 103. Multiple casters 105 are provided at the bottom of the base 101. The gas spring 102 is mounted on the base 101, and the display 103 is connected to the piston rod of the gas spring 102. A switch 112 for the gas spring 102 is provided on the base 101. By pressing the switch 112, the piston rod of the gas spring 102 can be moved, thereby adjusting the height of the display 103. A first connecting rod 118 is slidably connected to the base 101. The first connecting rod 118 can move relative to the base 101 in the width direction of the base 101. A caster wheel 105 is provided at one end of the first connecting rod 118. By moving the first connecting rod 118, the cross-sectional area in the width direction of the base 101 can be increased, thereby increasing the support effect of the base 101. This allows the electronic whiteboard to move along the width direction of the base 101 and move the electronic whiteboard in multiple directions, improving the ease of use of the electronic whiteboard.
[0037] Furthermore, the base 101 is provided with a through groove, and a support block 104 is provided in the through groove. One end of the support block 104 is rotatably connected to the through groove. One end of the support block 104 is provided with a first connecting shaft 106. The inner wall of the through groove is provided with a first connecting groove corresponding to the first connecting shaft 106. The first connecting shaft 106 is provided with a protrusion 114. The side wall of the first connecting groove is provided with a first movable groove 116 for the protrusion 114 to move. The first movable groove 116 has an arc-shaped structure.
[0038] One end of the support block 104 is provided with an abutment block 107, the abutment block 107 is provided with a guide rod 108, the support block 104 is provided with a guide groove corresponding to the guide rod 108, and the abutment block 107 is also provided with a spring 109, one end of the spring 109 is fixed to the support block 104; the spring 109 makes the abutment block 107 always have a tendency to move away from the support block 104.
[0039] The support block 104 has a through cavity, and the abutment block 107 is rotatably connected to the rotating rod 110. The rotating rod 110 passes through the through cavity, and the inner wall of the through cavity is provided with multiple fixing blocks 115. The rotating rod 110 is provided with multiple fixing grooves 117 corresponding to the fixing blocks 115. One end of the fixing groove 117 is provided with a first sliding groove corresponding to the fixing block 115. One end of the rotating rod 110 is provided with a turntable 111.
[0040] When the electronic whiteboard is in use, pushing the support block 104 downwards flips it from a horizontal to a vertical position. The cooperation between the protrusion 114 and the first movable groove 116 allows the support block 104 to rotate only within a range of 0-90°. The abutment block 107 rotates with the support block 104 and rests against the ground. Rotating the turntable 111 causes the fixing block 115 to insert into the fixing groove 117 on the rotating rod 110, fixing the rotating rod 110, thereby fixing the abutment block 107. The connecting block 107 increases the friction between the base 101 and the ground, improving the stability of the electronic whiteboard. When the electronic whiteboard needs to be moved, the rotating rod 110 is rotated to make the fixing block 115 disengage from the fixing groove 117. The fixing block 115 is in the first movable groove 116. The connecting block 107 is pulled towards the support block 104. After the connecting block 107 moves upward and disengages from the ground, the support block 104 is rotated to flip the support block 104 to a horizontal position for storage.
[0041] Furthermore, the base 101 has a mounting block 125 at its bottom, and the mounting block 125 has a second movable groove. The first connecting rod 118 is inserted into the second movable groove, and the first connecting rod 118 has a slider 121. The inner wall of the second movable groove has a second sliding groove for the slider 121 to move. The slider 121 and the second sliding groove cooperate to guide the movement of the first connecting rod 118.
[0042] The first connecting rod 118 is provided with a second connecting groove, and a second connecting shaft 119 is provided in the second connecting groove. A limiting plate 120 is provided at one end of the second connecting shaft 119, and a universal wheel 105 is provided at the other end of the second connecting shaft 119. The limiting plate 120 is used to prevent the second connecting shaft 119 from coming out of the second connecting groove.
[0043] Furthermore, the base 101 is provided with a third movable groove, which is connected to the slide groove. The third movable groove is provided with a movable rod 122, and the two ends of the movable rod 122 are respectively provided with limit blocks 123. The slider 121 is provided with a limit groove corresponding to the limit blocks 123.
[0044] The movable rod 122 is provided with a second connecting rod 124, and the middle part of the second connecting rod 124 protrudes upward; the base 101 is provided with a third connecting rod, and a push plate 113 is rotatably connected to the third connecting rod. The middle part of the push plate 113 is rotatably connected to the third connecting rod, and one end of the push plate 113 is located below the second connecting rod 124. The push plate 113 is in a horizontal state when it is not under force.
[0045] When the electronic whiteboard needs to be moved along the width of the base 101, the support block 104 is pushed down and flipped, and the abutment block 107 abuts against the ground to provide support for the electronic whiteboard. The second connecting shaft 119 is rotated to disengage the caster wheel 105 from the ground. One end of the push plate 113 is pushed to move, causing the other end of the push plate 113 to push the second connecting rod 124 to move. The second connecting rod 124 drives the movable rod 122 to move, causing the limiting block 123 to disengage from the limiting groove and pull the first connecting rod 118 outward. Since the caster wheel 105 is not in contact with the ground at this time, the first connecting rod 118 can be easily pulled to adjust the position of the caster wheel 105. After adjustment, the slider 121 moves to the other end of the first slide groove, and the push plate 113 is released. The movable rod 122 drives the limiting block 123 to fall, so that the limiting block 123 inserts into the limiting groove and fixes the slider 121 in the first slide groove, and fixes the first connecting rod 118. After adjusting the four universal wheels 105 in the above manner, the electronic whiteboard can be moved in multiple directions and the stability of the electronic whiteboard movement can be ensured. After the first connecting rod 118 is fully pulled out, the turntable 111 is rotated to flip the support block 104 and store the support block 104 in the through groove, so that the support block 104 is disengaged from the ground to facilitate the movement of the electronic whiteboard.
[0046] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
