[0022] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0023] like Figure 1 and Figure 2 As shown, a self-locking flip table includes a tabletop 11 and a pair of legs 12. The legs 12 are arranged in pairs on both sides of the tabletop 11. The legs 12 on the same side are connected at an angle. A connecting plate 21 is connected between the two legs 12 to form a triangular structure. The legs 12 and the connecting plate 21 are both located under the tabletop 11 for easy support.

[0024] A crossbar 13 is fixedly connected between the connecting plates 21 on both sides. The two ends of the crossbar 13 are connected to the connecting plates 21 by bolts, which facilitates disassembly.

[0025] Furthermore, a connecting block 31 is fixedly connected to the lower end face of the tabletop 11. There are two connecting blocks 31, located at both ends of the tabletop 11 respectively. The connecting blocks 31 are close to the connecting plate 21 and are used to connect with the connecting plate 21.

[0026] like Figure 3 and Figure 4 As shown, the connecting block 31 is composed of several iron plates. The connecting block 31 has a connecting cavity 32 inside. A sleeve is installed on the inner wall of the connecting cavity 32, and a rotating shaft 37 is rotatably connected inside the sleeve. The rotating shaft 37 passes through and rotatably connects to the connecting block 31. The connecting block 31 is connected to the connecting block 21 via the rotating shaft 37, facilitating the flipping of the tabletop.

[0027] Meanwhile, the lower end face of the connecting block 31 is provided with a positioning groove 38, and both sides of the positioning groove 38 pass through the connecting block 31. The positioning groove 38 is used to accommodate the crossbar 13. When the tabletop 11 is flipped to the horizontal, both ends of the crossbar 13 are located in the positioning groove 38, which supports the tabletop 11 and ensures the stability of the tabletop 11.

[0028] The connecting block 31 is equipped with a locking device to restrict the tabletop 11 from flipping, preventing accidental contact with the tabletop 11 during use.

[0029] The locking device includes a locking wrench 41, which is located in the connecting cavity 32. The locking wrench 41 is rotatably connected to the inner wall of the connecting cavity 32. One end of the locking wrench 41 is rotatably connected to the inner wall of the connecting cavity 32 via a shaft. The other end of the locking wrench 41 is a free end. A protrusion 42 is connected to the free end of the locking wrench 41. The connecting cavity 32 has a through-hole 36 below the protrusion 42. The protrusion 42 can extend out of the 36. A locking rod 43 is connected to the protrusion 42 outside the 36. The locking rod 43 is used to engage with the connecting plate 21 to achieve locking.

[0030] The locking plate 43 and the rotating shaft 37 are located on both sides of the connecting plate 21. When the locking rod 43 and the connecting plate 21 are engaged, the connecting block 31 cannot rotate around the rotating shaft 37, thus achieving the locking effect.

[0031] Furthermore, the rotating end of the locking wrench 41 is connected to a handle 14, which is located on the outside of the connecting block 31. The rotating shaft of the locking wrench 41 passes through the connecting block 31 and is fixedly connected to the handle 14. The locking wrench 41 can be controlled to work through the handle 14 to perform the locking and unlocking functions.

[0032] The connecting plate 21 and the locking lever 43 on the locking wrench 41 work together to achieve a locking effect.

[0033] like Figure 5 As shown, the side wall of the connecting plate 21 is provided with a slot 24, which runs through the front and back and the opening of the slot 24 is angled downward, so that the locking rod 43 can rotate to be inserted into or disengaged from the slot 24. Furthermore, the connecting plate 21 is provided with a sliding groove 22 below the slot 24, which is connected to the slot 24. At the same time, the inner wall of the sliding groove 22 is arc-shaped, so that the locking rod 43 can slide out.

[0034] Meanwhile, the connecting plate 21 is provided with a guide groove 23 above the slot 24. The guide groove 23 and the slot 24 are connected, but the guide groove 23 is also provided with a slope. After the locking wrench 21 drives the locking rod 43 to disengage from the slot 24, the locking rod 43 can be re-engaged through the guide groove 23 and the slot 24. In order to facilitate the locking rod 43 to enter the slot 24, an embedded chamfer 25 is provided between the guide groove 23 and the slot 24 to facilitate the locking rod 43 to enter the slot 24.

[0035] The chamfer 25 also facilitates the separation of the locking rod 43 and the slot 24. In this embodiment, when the wrench 41 rotates the locking rod 43 by 10 degrees, the locking rod 43 can be inserted into the chamfer 25 and disengaged. The lower end of the wrench 41 contacts the bottom of the connecting cavity 32 and cannot be rotated further. At this time, the table 11 can be flipped over, making the operation convenient.

[0036] The locking wrench 41 has a through-hole cavity 45. The cavity 45 has a connection port 44 above the protrusion 42. The connecting cavity 32 has a movable rod 33 above the connection port 36. A return spring 34 is provided between the movable rod 33 and the locking wrench 41. One end of the return spring 34 is connected to the movable rod 33, and the other end of the return spring 34 is connected to the connection port 44. The return spring 34 is always in a stretched state and will always provide an upward force to the locking wrench 41. When the locking rod 43 slides through the embedded chamfer 25 in the guide groove 23, the external force applied by the return spring 34 can control the locking rod 43 to enter the slot 24, so as to achieve the self-locking effect during the lowering of the table 11.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
