[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Please refer to Figure 1 , the embodiment of the present application provides a buckle type turnover device, which comprises a turnover arm 1, a supporting arm 2, a first screw rod 3, a hanging buckle 4 and the like. The various components of the present embodiment will be described in detail below with reference to the drawings.

[0025] As Figure 1 and Figure 2 , the cross sections of the turnover arm 1 and the supporting arm 2 can be arranged in an inverted U-shaped structure, the bottom of the turnover arm 1 is rotatably connected to the inner side of the front end of the supporting arm 2, the first screw rod 3 is horizontally connected between the inner sides of the front part of the supporting arm 2, the end of the hanging buckle 4 is rotatably sleeved on the first screw rod 3, and the front end of the hanging buckle 4 is arranged to pass through and be clamped in the clamping hole 11 arranged on the front surface of the turnover arm 1.

[0026] As shown in Figure 5 , the front end of the support arm 2 can be horizontally recessed with a first avoidance slot 23 for avoiding the turnover arm 1, and the middle of the front end of the support arm 2 can be horizontally recessed with a second avoidance slot 24 for avoiding the hanging buckle 4.

[0027] Specifically, the rear end of the turnover arm 1 can be recessed with a third avoidance slot 12 corresponding to the first avoidance slot 23 on the two side walls.

[0028] As shown in Figure 1 and Figure 6 , in specific implementation, the turnover arm 1 can be upwardly turned 90 degrees relative to the support arm 2, and then be positioned by the hanging buckle 4 and the clamping hole 11 to achieve the turnover positioning of the turnover arm 1.

[0029] The first avoidance slot 23 of the support arm 2 and the third avoidance slot 12 of the turnover arm 1 can avoid interference with the turnover arm 1 during the turnover process, ensuring smooth turnover movement of the turnover device, and the second avoidance slot 24 can provide space for the rotation of the hanging buckle 4. The first screw rod 3 provides stable rotation support for the hanging buckle 4, ensuring the flexibility of the rotation of the hanging buckle 4. The turnover arm 1 can be upwardly turned relative to the support arm 2, and the clamping hole 11 opened on the front face is used to cooperate with the hanging buckle 4 to achieve the effect of turnover positioning.

[0030] As shown in Figure 3 , it can also include a second screw rod 7 and a tension spring 8. The second screw rod 7 is fixedly connected to the two inner sides of the support arm 2 and located below the first screw rod 3. A through hole is provided in the middle of the front end of the hanging buckle 4. The tension spring 8 has a hook on one end which hooks on the second screw rod 7, and a hook on the other end which hooks in the through hole of the hanging buckle 4. The tension spring 8 can provide tension to the hanging buckle 4.

[0031] In specific implementation, when the turnover arm 1 is turned 90 degrees relative to the support arm 2 and positioned by the hanging buckle 4, the tension of the tension spring 8 makes the hanging buckle 4 more stably clamped with the clamping hole 11, preventing the hanging buckle 4 from accidentally detaching from the clamping, and enhancing the stability of the turnover device.

[0032] In this embodiment, it can also include a connecting sliding block 5 and a locking screw 6. The connecting sliding block 5 is provided with two blocks. Two or more first adjusting holes 21 are provided on the two side faces of the rear part of the support arm 2 in parallel. The two connecting sliding blocks 5 are fixedly installed on the two inner side faces of the support arm 2 by the locking screw 6 passing through the first adjusting holes 21. Two second adjusting holes 22 are provided on the two inner side faces of the front part of the support arm 2 in parallel for the first screw rod 3 to pass through. The two ends of the first screw rod 3 pass through the two connecting sliding blocks 5 and the second adjusting holes 22 respectively.

[0033] As shown in Figure 4As shown, the bottom of the limiting end 401 of the hook 4 can be recessed upward to form a groove 41 whose shape corresponds to the shape of the opening edge of the snap hole 11. The side of the groove 41 near the limiting end 401 is slightly inclined outward to form a slope 42.

[0034] To ensure precise engagement with the slot 41 of the hook 4, the snap-fit ​​hole 11 can preferably be configured as a rectangular hole. The rectangular hole's regular shape facilitates processing and allows for precise engagement with the slot 41, improving positioning accuracy.

[0035] Specifically, the rotating end 402 of the hook 4 can be tilted from back to front between the bottom surface of the hook and the limiting end 401.

[0036] Furthermore, the beveled surface 42 and the inclined bottom surface of the hook 4 make it easier to engage and disengage the hook 4.

[0037] like Figure 7 As shown, in specific implementation, if the flip arm 1 becomes loose or needs to be adjusted, the position of the connecting slider 5 can be adjusted backward along the length direction of the first adjusting hole 21 by loosening the locking screw 6, thereby changing the position of the first screw 3 and the hook 4. Since one side of the limiting end 401 of the hook 4 is slightly inclined outward to form a slope 42, an inward component force will be generated during the backward movement, which can better press the flip arm 1 inward and prevent the flip arm 1 from becoming loose.

[0038] In summary, this utility model achieves a snap-fit ​​by having the front end of the hook pass through the snap-fit ​​hole on the front of the flip arm, which can stably position the flip arm at a position that is flipped 90 degrees upward relative to the support arm. Compared with traditional flippers without positioning function, the flip arm and support arm can be flipped and positioned by using the combination of hook and snap-fit ​​hole. It can meet the needs of flipping and positioning functions in different scenarios and has strong versatility.

[0039] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
