DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 to Figure 7As shown, a computer flip table with adjustable crescent legs comprises a connecting frame 1 for adjusting the length of the crescent legs, a supporting frame 6 for adjusting the height of the crescent legs and a flippable desktop 7, wherein the connecting frame 1 comprises a first side frame 2 connected to the supporting frame 6, a second side frame 3 for changing the coverage area of ​​the connecting frame 1, a sleeve rod 4 for stabilizing the entire connecting frame 1 and a rotating shaft 5 for controlling the rotation of the desktop 7, the connecting frame 1 is installed at the center of the lower surface of the desktop 7 and is rotatably connected thereto, two supporting frames 6 are respectively installed on both sides of the connecting frame 1, four sleeve rods 4 are respectively installed around the connecting frame 1, the first side frame 2 is installed in the sleeve rod 4, the second side frame 3 is installed at both ends of the first side frame 2, and the rotating shaft 5 is arranged on the upper surface of the center of the connecting frame 1.

[0027] The computer flip table utilizes the flipping of the rectangular desktop 7 to increase or decrease the available area of ​​the entire desktop 7, so that the computer flip table is suitable for different work scenes. The support frame 6 serves as a crescent foot. The first side frame 2 and the second side frame 3 are extended and retracted on the connecting frame 1 to drive the movement of the two support frames 6, thereby adjusting the length between the two crescent feet to ensure that the support frame 6 can stably support the desktop 7. The sleeve rod 4 is used to provide guidance and limit for the movement of the first side frame 2. At the same time, the support frame 6 can change the relative distance between itself and the ground to adjust the height of the desktop 7, so that it is suitable for users of different heights. The rotating shaft 5 is used to adjust the direction of the desktop 7 to avoid the corner of the desktop 7 facing the user.

[0028] See also Figure 3 and Figure 4 As shown, the first side frame 2 includes an insertion rod 21, a support arm 22 and a first positioning hole 23. The insertion rod 21 is installed on one side of the first side frame 2 and aligned with the sleeve rod 4. The support arm 22 is arranged on the first side frame 2 and is perpendicular to the insertion rod 21. The first positioning hole 23 is arranged on the support arm 22.

[0029] The insertion rod 21 is nested and slidably connected with the sleeve rod 4 on the connecting frame 1, the support arm 22 is used to provide guidance and limit for the movement of the second side frame 3, and the first positioning hole 23 is used to accurately control the telescopic length of the first side frame 2 and facilitate the parking of the first side frame 2 to prevent it from continuing to slide.

[0030] See also Figure 3 As shown, the second side frame 3 includes a gasket 31, a chimeric arm 32 and a second positioning hole 33. The gasket 31 is arranged on the upper surface of the second side frame 3. The chimeric arm 32 has two arms arranged perpendicularly to each other on the second side frame 3. The second positioning hole 33 is arranged on the chimeric arm 32.

[0031] The gasket 31 is used to reduce the friction between the second side frame 3 and the lower surface of the desktop 7 to increase the service life of both. The engaging arm 32 is nested and slidably connected with the support arm 22 on the first side frame 2. The second positioning hole 33 has the same size as the first positioning hole 23, so as to facilitate relative fixation of the first side frame 2 and the second side frame 3 at the same time.

[0032] See also Figure 5 As shown, the support frame 6 includes a bracket 61, a third positioning hole 62, a height limiting rod 63 and a pin 64, the bracket 61 is installed on the top of the support frame 6, the third positioning hole 62 is set on the bracket 61, the height limiting rod 63 is set at the bottom of the support frame 6, and the pin 64 is installed in the third positioning hole 62.

[0033] The bracket 61 is used to support the entire connecting frame. The third positioning hole 62 has the same size as the first positioning hole 23 and the second positioning hole 33. The bracket 61 and the connecting frame 1 after the extension and retraction are fixed by passing the pin 64 through the three. Since the height of the desktop 7 required by users of different heights does not vary much, the height of the desktop 7 can be fine-tuned using the height limiting rod 63.

[0034] See also Figure 5 and Figure 6 As shown, the height limit rod 63 includes a support foot 65, a slot 66, a mounting strip 67 and a card plate 68. The support foot 65 is installed at both ends of the height limit rod 63, the slot 66 is set at the center of the height limit rod 63, the mounting strip 67 is set on the surface of the support frame 6, and the card plate 68 is installed on the side of the height limit rod 63.

[0035] The support legs 65 are used to hold up the support frame 6. The height of the table top 7 can be fine-tuned by moving the support frame 6 up and down in the slot 66. The mounting strip 67 is docked with the card plate 68 to fix the height of the support frame 6. At the same time, the mounting strip 67 on the surface of the support frame 6 can increase the ventilation capacity of the bottom of the table top 7, thereby increasing the comfort of use of the entire table.

[0036] See also Figure 5 As shown, the support foot 65 includes a threaded rod 651, a knob 652 and a mounting hole 653. The mounting holes 653 are set at both ends of the height limiting rod 63. The threaded rod 651 is installed on the upper surface of the support foot 65 and passes through the mounting hole 653. The knob 652 is installed on the top of the threaded rod 651.

[0037] When the height limiting rod 63 has adjusted the appropriate height of the table top 7, the knob 652 is turned to make the threaded rod 651 push the support foot 65 to lift the height limiting rod 63 to prevent the support frame 6 from touching the ground from the slot 66 when the height limiting rod 63 is too high, causing damage to the support frame 6. The mounting hole 653 is used to position the threaded rod 651 and ensure the stability of the height of the table top 7 by engaging with the threaded rod 651.

[0038] See also Figure 1 to Figure 7 As shown, the desktop 7 includes a groove 71, a connecting plate 72 and a connector 73. The connecting plate 72 is arranged around the desktop 7 and fits with the desktop 7. The groove 71 is arranged at the connection between the connecting plate 72 and the desktop 7, and the connector 73 is installed in the groove 71.

[0039] The groove 71 is used to install the connector 73. By pulling the connector 73, the connecting plate 72 can be flipped on the upper surface of the desktop 7. When the connecting plate 72 is around the desktop 7, the computer desk has the largest usable area. When the connecting plate 72 is attached to the upper surface of the desktop 7, the computer desk has the smallest usable area. At this time, the lower surface of the connecting plate 72 serves as the usable surface of the computer desk.

[0040] See also Figure 7 As shown, the connector 73 includes a telescopic rod 731, a spring 732 and a rotating rod 733. The rotating rod 733 is arranged on both sides of the connector 73. The telescopic rod 731 is installed in the groove 71 and is vertically connected to the rotating rod 733. The spring 732 is surrounded by the outer side of the telescopic rod 731.

[0041] The telescopic rod 731 and the spring 732 enable the connecting plate 72 to fit firmly with the desktop 7 before and after flipping, thereby ensuring the stability of the entire computer desk. The rotating rod 733 is used to release the spatial constraints of the connector 73, ensuring that the connector 73 can be pulled to adjust the connecting plate 72.

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
