[0044] In the description of the application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "setting", "connection" and the like should be understood broadly, for example, "connection" can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, or indirectly connected through intermediate medium, but the connection at each place does not affect the multi-position folding of the present application. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The creativity of the present application lies in that the adjustable angle ratchet telescopic mechanism is used to realize the height adjustment, grading self-locking and fixing of the notebook computer support, and folding up and down after reaching a certain height. Unlike the conventional height adjustment mode of notebook computer support, the height adjustment of notebook computer support is more convenient, stable and fast, and the purpose of simply adjusting the height without taking off the computer is achieved.

[0046] As Figures 1-25 As shown in a specific embodiment of a notebook computer support using an adjustable telescopic structure, a notebook computer support using an adjustable telescopic structure comprises two groups of adjusting supports, and the two groups of adjusting supports are connected through foldable connecting rods. Each group of adjusting supports comprises a supporting plate 14, an adjusting rod, and a bottom plate 15. The principle of the foldable supporting plate 14 is as follows: Figure 22 It can be folded left and right to open, and the specific structure is as follows: Figures 3-4, give two tray 14 opposite and outward force, so that two tray 14 left and right open, shrink the same reason. The bottom of the tray 14 hinge at the front end of the bottom plate 15, the bottom of the adjusting rod hinge at the rear end of the bottom plate 15, the top of the tray 14 and the top of the adjusting rod hinge, the adjusting rod includes sleeve 5, slider one 7, slider two 9, slider three 10, control component;

[0047] The bottom of the sleeve 5 hinge at the rear end of the bottom plate 15, the top of the slider one 7 and the top of the tray 14 hinge, the slider one 7 and the slider two 9 are connected, the slider two 9 and the slider three 10 are connected, the slider one 7, the slider two 9 and the slider three 10 constitute a telescopic rod, and the telescopic rod can be embedded or extended in the sleeve 5; the sleeve 5 is provided with a sliding groove, a plurality of tooth grooves are formed on one side edge of the sliding groove, and the tooth opening of the tooth groove is curved upward with an arc. A plurality of tooth grooves constitute a strip-shaped tooth groove. The control component is connected to the slider three 10, and the control component can be engaged or disengaged from any one of the tooth grooves to adjust the position of the telescopic rod in the sleeve 5.

[0048] The control component includes a swing rod 8 and a torsional spring 10.1 connected with a rotating part. The swing rod 8 is rotatably connected to the slider three 10, and a No. 1 socket and a No. 2 socket are spaced apart on the swing rod 8 at the center of rotation. The No. 1 socket is located between the outer end of the torsional spring 10.1 and the No. 2 socket, the opening of the No. 1 socket is larger than that of the No. 2 socket, and the opening of the No. 2 socket is matched with the outer end of the torsional spring 10.1. The free end of the swing rod 8 is hinged with a cylindrical body 8.2, and the outer end of the torsional spring 10.1 can alternatively act in the No. 1 socket and the No. 2 socket to press the swing rod 8 to rotate and make the cylindrical body 8.2 on the free end of the swing rod 8 lift or move downward.

[0049] Control mode:

[0050] Mode 1: twist the rotating part to make the outer end of the torsional spring 10.1 lift, and push the swing rod 8 to rotate clockwise. After the rotating part is released, the outer end of the torsional spring 10.1 acts on the No. 2 socket. Under the action of the torsional spring 10.1, the cylindrical body 8.2 on the free end of the swing rod 8 lifts and rests on the side of the sliding groove without tooth groove, so as to move the telescopic rod to completely embed in the sleeve 5. Flow chart: see Figures 12-15 At this time, under the action of the outer end of the spring 10.1, the cylindrical body 8.2 at the free end of the swing rod 8 is lifted and separated from the tooth groove.

[0051] Way 2: twist the rotating part so that the outer end of the torsion spring 10.1 is lifted, the pendulum rod 8 is rotated counterclockwise under the action of gravity of the cylinder 8.2, and the outer end of the torsion spring 10.1 acts on the first notch after the rotating part is released. Under the action of the torsion spring 10.1, the cylinder 8.2 on the free end of the pendulum rod 8 moves down and can be clamped in the tooth groove. Pulling the telescopic rod along the bending direction of the tooth groove can clamp the cylinder 8.2 in different tooth grooves to realize step-by-step control of the height adjustment of the adjusting rod. Moving the telescopic rod gradually releases the sleeve 5. Flow chart: see Figures 16-21 , and Figure 16 、 Figure 18 、 Figure 19 The state in the above is a state in which the height adjustment of the adjusting rod is good.

[0052] Specifically, as shown in Figures 12 to 21 , the sleeve 5 and the slider three 10 are in different states, and the control component (the pendulum rod 8, etc.) is in a state in which the elastic force at the top end of the torsion spring 10.1 is downward.

At this time, the control component (i.e., the second notch of the pendulum rod) is given a backward and downward pulling force by the torsion spring 10.1, so that the cylinder 8.2 is lifted, and the cylinder 8.2 of the control component (the pendulum rod 8, etc.) touches the upper end of the sliding groove on the sleeve 5. In this state, the slider three 10 moves left and right easily.

[0054] After moving as shown in Figures 12 to 15 , the adjusting support (the telescopic rod) reaches the shortest state, and at this time, the adjusting support, as shown in Figure 11 , is the lowest state of the computer support. When it is necessary to adjust the height of the notebook computer support, an upward force is given to the adjustable supporting plate 14, so that the upward force is transmitted to the slider one 7, and the slider one 7 and the slider two 9 are connected through the slider three 10, so that the slider three 10 is given an upward force as shown in Figures 15 to 19 , so that the step is fixed, and after being adjusted to a suitable height, the process is ended. After the adjusting support is adjusted to the highest height as shown in Figure 6 , the slider two 9 is given an upward force again, so that the slider two 9 is separated from the sleeve 5, and reaches a state as shown in Figure 7 , the notebook computer support is folded up and down, and returns to a state as shown in Figure 4 .

[0061] As shown in the state Figures 14-15 As shown in the state, due to the design of the waist-shaped groove, when the cylindrical body 8.2 of the control component (the swing rod 8, etc.) passes through the left upper high point of the arc-shaped tooth groove, the top end of the torsion spring 10.1 is separated from the second aperture (the small gap) to the first aperture (the large gap), in order to improve the success of the separation of the top end of the torsion spring 10.1 from the second aperture to the first aperture, the opening of the first aperture can be inclined towards the second aperture, at this time, the torsion spring 10.1 cannot block the control component (the swing rod 8, etc.), at this time, the top of the torsion spring is blocked at the second aperture (the gap inclined surface), which is large, at this time, the torsion spring 10.1 will give the control component (the swing rod 8, etc.) a smaller force, and the force is just enough to open the cylindrical body 8.2 at the bottom of the tooth groove, pull the sliding block 7, and adjust the bracket to be fixed in stages.

[0062] Therefore, through the design of the waist-shaped groove communicated by the sliding groove, the function of switching the outer end of the torsion spring 10.1 between the first aperture and the second aperture in the pulling sliding block 7 can be realized without adopting the rotating part 10.3, etc., and the free grading adjustment is realized.
