DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown in the figure, a foldable table top that can be quickly unfolded and locked includes a support rod 1, an internal slide groove 2 is opened inside the support rod 1, the internal slide groove 2 is opened in the middle of the support rod 1, the internal slide groove 2 does not pass through the support rod 1, and a slide rod 3 is installed inside the internal slide groove 2. The internal slide groove 2 opened inside the support rod 1 can make the slide rod 3 slide and rise inside the internal slide groove 2, and the angle and height between the left rod 11 and the right rod 12 connected on the right side can be adjusted, which is convenient for adjusting the angle and height of the device.

[0026] A slot 4 is provided on both the front and rear sides of the support rod 1, and the height between the slot 4 and the internal slide groove 2 is equal. A latch tooth 5 is fixedly installed on the side wall of the slot 4. During use, the slot 4 provided on both the front and rear sides of the support rod 1 is provided with a latch tooth 5. The latch tooth 5 can fix the position of the internal slide bar 3, so that the slide bar 3 can be fixed at a height, thereby preventing the slide bar 3 from sliding inside the device after the height is fixed, which affects the stability of the device installation.

[0027] A top rotating shaft 6 is installed on the top of the support rod 1, and the support rod 1 is connected to the support rod 1 through the top rotating shaft 6. The support rod 1 and the support rod 1 form a rotating structure through the top rotating shaft 6. Four groups of top rotating shafts 6 are symmetrically arranged. During use, the support rod 1 can rotate with the left table board 7 and the right table board 14 through the top rotating shaft 6. When rotating, the angle between the support rod 1 and the left table board 7 and the right table board 14 is adjusted to facilitate the rotation and folding of the support rod 1 and the left table board 7. There are four groups of top rotating shafts 6, so that the support rod 1 can evenly support the device at the bottom of the left table board 7 and the right table board 14, making the device more stable.

[0028] Two groups of fixed plates 8 are installed parallel to the sides of the top rotating shaft 6. The two groups of fixed plates 8 are rotatably connected by connecting hinges 9. The two groups of fixed plates 8 form a rotating structure through the connecting hinges 9. There are two groups of fixed plates 8, and the two groups of fixed plates 8 can be rotated by connecting hinges 9. When rotating, the two groups of fixed plates 8 can be folded.

[0029] The fixed plate 8 is provided with two groups on the left and right sides. The left table board 7 is fixedly installed on the top of the left fixed plate 8. A hinge 13 is provided at the bottom of the left table board 7. The left and right sides of the hinge 13 are respectively provided with a first connector 131 and a second connector 132. A connecting piece 133 passes through one end of the second connector 132. The right table board 14 is fixedly installed on the top of the fixed plate 8. The two groups of fixed plates 8 are respectively fixed to the left table board 7 and the right table board 14. Therefore, the left table board 7 and the right table board 14 can be rotated and folded by cooperating with the fixed plate 8 and the connecting hinge 9 at the bottom, thereby improving the overall flexibility of the device.

[0030] Example 2

[0031] like Figure 2-Figure 7As shown, this embodiment further illustrates Example 1, the bottoms of the left and right groups of fixed plates 8 are both installed with bottom rotating shafts 10, the bottom of the left bottom rotating shaft 10 is connected and installed with a left rod 11, and the bottom of the right bottom rotating shaft 10 is connected and installed with a right rod 12, the left rod 11 and the right rod 12 are installed through a central connecting shaft 15, and the left rod 11 forms a rotating structure with the right rod 12 through the central connecting shaft 15. During use, when the fixed plates 8 are folded through the connecting hinges 9, the bottom right rod 12 and the left rod 11 will both be rotated and folded between the top bottom rotating shaft 10 and the fixed plates 8, thereby improving the overall flexibility of the device, and at the same time, during the folding process, the left rod 11 and the right rod 12 will also be rotated through the central connecting shaft 15, so that the left rod 11 and the right rod 12 can be connected together to prevent the device from falling apart.

[0032] The bottom ends of the right rod 12 and the left rod 11 are connected to the sliding rod 3, and the right rod 12 forms a sliding lifting structure with the support rod 1 through the sliding rod 3. When the left rod 11 and the right rod 12 adjust the angle between the left table board 7 and the right table board 14 at the top, the height can be adjusted by sliding the bottom sliding rod 3 inside the internal slide groove 2. At this time, when the left table board 7 and the right table board 14 are folded, the sliding rod 3 will also change its position inside the internal slide groove 2. In the process of supporting the left table board 7 and the right table board 14, the position of the sliding rod 3 inside the device can also be fixed by the cooperation between the sliding rod 3 and the latch 5, thereby improving the stability of the device.

[0033] Working principle: First, when the device is in use, the left table board 7 and the right table board 14 are fixed by the fixing plate 8 at the bottom, and then the fixing plates 8 are rotated through the connecting hinge 9, at this time, the left table board 7 and the right table board 14 will be folded, and the angle between the left table board 7 and the right table board 14 will be adjusted. During the folding process of the device, the left rod 11 and the right rod 12 at the bottom of the fixing plate 8 are close to each other. At this time, the sliding rod 3 at the bottom of the left rod 11 and the right rod 12 slides downward inside the internal slide groove 2, and at the same time, the support rod 1 is folded inward with the left table board 7 through the top rotating shaft 6 at the top, so that the device as a whole can be folded together to reduce the volume of the device. When the device is unfolded, the position of the sliding rod 3 at the end of the left rod 11 and the right rod 12 inside the internal slide groove 2 can be adjusted to adjust the overall height of the device, and then the sliding rod 3 can be engaged with the internal adjustment device of the latch tooth 5 to improve the stability of the device.
