Embodiment 1
[0024] This embodiment provides a support frame for a notebook computer, such as Figure 1-2 As shown, it includes a placement platform 1 for placing a computer 4, a bracket 2 supporting the placement platform 1, and a base 3 for installing the bracket 2, wherein;
[0025] The base 3 is provided with a horizontally rotatable mounting plate 31, the bracket 2 includes a first pole 21, a second pole 22 and a third pole 23, and the two ends of the first pole 21 pass through the rotating shaft respectively. It is connected with the installation plate 31 and the placement platform 1; the top end of the second pole 22 is connected to the placement platform 1 through a rotating shaft, and the bottom end slides along the first pole 21, wherein the first pole 21, the second pole 22 and the placement platform 1 form a triangular area; the top end of the third pole 23 slides along the first pole 21, and the bottom end is connected to the mounting plate 31 through a rotating shaft. The fir...
Embodiment 2
[0029] On the basis of Embodiment 1, this embodiment further defines: the upper and lower surfaces of the first support rod 21 are respectively provided with an upper chute and a lower chute, and the bottom end of the second support rod 22 is provided with an upper chute. The first sliding block that slides inside, the top end of the third support rod 23 is provided with a second sliding block that slides in the sliding groove.
[0030] Manually make one end of the second pole 22 and the third pole 23 slide along the upper chute or the lower chute, which is convenient to move. Position after sliding to the specified position. Wherein the positioning can adopt the frictional force between the slide block and the chute or any positioning device in the prior art.
Embodiment 3
[0032] On the basis of Embodiment 2, this embodiment further defines that: the groove bottoms of the upper chute and the lower chute are provided with positioning protrusions, and the bottom surface of the first slider and the top surface of the second chute are provided with Positioning grooves with matching protrusions in size and shape.
[0033] The positioning is realized by matching positioning protrusions and positioning grooves, and no external positioning mechanism is required. When the slider and the chute need to slide relative to each other, use upward force to make the slider slide along the upper surface of the chute, and the external force needs to be canceled at a fixed position, and the slider will receive the downward pressure provided by the placement table 1 and the computer 4, thereby Make the positioning protrusion and the positioning groove cooperate to play the role of positioning.
