As shown in fig. 3-6, by controlling the length relationship between the unlocking tooth 33 and the reset tooth 32 and the gear tooth 31, the unlocking tooth 33 can drive the pawl 4 to swing counterclockwise, so that the connection point of the spring 5 and the pawl 4 passes through the straight line L where the connection point of the spring 5 and the connection plate 61 and the connection point of the rotating shaft 8 and the pawl 4 are located from top to bottom. The reset tooth 32 can drive the pawl 4 to swing clockwise, so that the connection point of the spring 5 and the pawl 4 passes through a straight line L where the connection point of the spring 5 and the connection plate 61 and the connection point of the rotating shaft 8 and the pawl 4 are located from bottom to top. Wherein the spring 5 is in a compressed state when the connection point of the spring 5 with the pawl 4 coincides with a straight line L where the connection point of the spring 5 with the connection plate 61 and the connection point of the rotation shaft 8 with the pawl 4 are located.
Of course, the designer skilled in the art may also set the unlocking tooth 33, the pawl 4 and the reset tooth 32 in a horizontal mirror image, where the unlocking tooth 33 can drive the pawl 4 to swing counterclockwise, so that the connection point of the spring 5 and the pawl 4 passes through the straight line L where the connection point of the spring 5 and the connection plate 61 and the connection point of the rotating shaft 8 and the pawl 4 are located from top to bottom. The reset tooth 32 can drive the pawl 4 to swing clockwise, so that the connection point of the spring 5 and the pawl 4 passes through a straight line L where the connection point of the spring 5 and the connection plate 61 and the connection point of the rotating shaft 8 and the pawl 4 are located from bottom to top. The working principle is the same as that of the above embodiment, and is not described here again.
Next, the working principle of the present stand is described in detail with reference to the specific structure of the present embodiment:
A flat state: the supporting plate 6 is in a horizontal state, the main body of the notebook is placed on the supporting plate 6, and the screen is normally turned over for use. The supporting plate 6 can be provided with a heat dissipation hole 62, so that the notebook computer can dissipate heat conveniently. At this time, the supporting plate 6 is positioned at one side of the desktop close to the user, so that the user can use the notebook conveniently.
Tilting state: when the notebook needs to be inclined at a certain angle, the supporting plate 6 is slightly lifted by hands, and the supporting plate 6 and the desktop form a certain inclination angle as shown in fig. 1. When the support is lifted to a proper angle, the hand is released, and the claw 41 on the pawl 4 is clamped into the gear teeth 31 of the ratchet wheel 3 to fix the support plate 6 and the support rod 2. When the pallet 6 is lifted again, the pawl 4 will engage with the other tooth 31, fixing the pallet 6 at another angle. After the notebook is used, the notebook can be closed, the supporting plate 6 is pushed to the maximum vertical angle, at the moment, the supporting plate 6 is closest to the supporting rod 2, the whole supporting plate 6 is positioned at the edge close to the back of the desktop, and is close to the wall, so that the desktop space is released.
When the pallet 6 needs to be put flat again, as shown in fig. 4, until the pallet 6 needs to be pushed toward the support rod 2 when the pallet 6 is at the maximum erection angle, the unlocking teeth 33 longer than the teeth 31 of the ratchet 3 drive the pawl 4 to swing counterclockwise, so that the connection point of the spring 5 with the pawl 4 passes through the straight line where the connection point of the spring 5 with the connection plate 61 and the connection point of the rotating shaft 8 with the pawl 4 are located from top to bottom. As shown in fig. 5, the pawl 41 is separated from the gear teeth 31 of the ratchet wheel 3 under the action of the elastic force of the spring 5, and is not contacted with the gear teeth 31 any more, so that the supporting plate 6 can swing up and down freely. In this way, the pallet 6 can be re-flattened. As shown in fig. 6, when the pallet 6 is put flat, the reset tooth 32 is in contact with the claw 41. In order to ensure that the reset tooth 32 can reliably contact the pawl 41, the tooth height of the reset tooth 32 can be set to be greater than the tooth height of the teeth 31 of the ratchet wheel 3. The reset tooth 32 pushes the pawl 4 again in the direction of the ratchet wheel 3, the pawl 41 coming into contact with the tooth 31 in preparation for fixing the oscillated pallet 6.
Preferably, the lower edge of the front face of the pallet 6 is provided with a support strip 63. The supporting strip 63 can ensure that the computer is fixed on the supporting plate 6 when the computer is nearly vertical, so as to prevent the computer from sliding down.
In addition, in order to prevent the support from overturning backwards, the bottom plate 1 is further provided with a limiting plate 9, the limiting plate 9 extends upwards from the bottom plate 1, and when the support rod 2 swings to the maximum stroke, the support rod is abutted against the limiting plate 9. Preferably, the included angle between the supporting rod 2 and the tabletop is less than 90 degrees when the supporting rod swings to the maximum stroke.
Preferably, the bottom surface of the bottom plate 1 is provided with a suction cup 10. It should be noted that, by setting the suction cup 10, the bottom plate 1 can be fixed on the desktop, so that the bracket is more stable and reliable when the user adjusts the inclination of the supporting plate 6. Similarly, the person skilled in the art can replace the suction cup with an anti-slip silica gel pad, and the bottom of the anti-slip silica gel pad can be provided with an anti-slip stripe, so that the anti-slip performance is further improved.
While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the utility model, such changes and modifications are also intended to be within the scope of the utility model.
