[0026] The reference signs in the drawings are: 1, U-shaped plate; 2, limit rod; 3, barb; 4, rotating shaft; 5, reset assembly; 6, frame; 21, limit plate; 31, handle; 51, torsion spring; 52, lower fixing rod; 53, upper fixing rod; 521, lower limit plate. Detailed implementation manners

[0027] This detailed implementation manner is a buckle assembly of a transfer machine, and its structural schematic diagram is as Figures 2 - 5 shown. The buckle assembly of the transfer machine includes:

[0028] U-shaped plate 1 is used to be inserted into the middle parts of two frames 6 of the transfer machine. There is a 2-mm gap between the inner space of the U-shaped plate 1 and the diameter of the middle part of the frame 6. This setting reduces the friction between the two when removing the U-shaped plate 1 from the frame 6;

[0029] Limit rod 2, one end of the limit rod 2 is fixedly connected to one of the frames 6;

[0030] Barb 3, one side of the barb 3 is rotatably connected to a rotating shaft 4. The end of the rotating shaft 4 far from the barb 3 is fixedly connected to the U-shaped plate 1. A limit groove matching with the limit rod 2 is opened at one end of the barb 3. When the barb 3 is stuck on the limit rod 2 through the limit groove, the fixation of the U-shaped plate 1 can be realized;

[0031] Reset assembly 5 is arranged between the U-shaped plate 1 and the barb 3, and the reset assembly 5 can drive the barb 3 to automatically reset.

[0032] A groove for accommodating the limit rod 2 is opened on one side of the U-shaped plate 1. Through the setting of this groove, the condition for the U-shaped plate 1 to be inserted into the two frames 6 is met, and after the U-shaped plate 1 is inserted into the two frames 6, the limit rod 2 is located in the groove opened on the U-shaped plate 1.

[0033] When the two frames 6 of the transfer machine need to be fixed after rotating and closing, first rotate the barb 3 to open the barb 3, then align the groove opened on the U-shaped plate 1 with the limit rod 2, insert the U-shaped plate 1 onto the two frames 6 and make the limit rod 2 located in the groove opened on the U-shaped plate 1, and then release the barb 3. Under the action of the reset assembly 5, the barb 3 can be driven to reset and close, so that the barb 3 is stuck on the limit rod 2 through the limit groove, realizing the fixation of the U-shaped plate 1. Under the limiting action of the U-shaped plate 1, the fixation after the two frames 6 rotate and close is realized, thereby preventing the two frames 6 from opening.

[0034] The reset assembly 5 includes a torsion spring 51 sleeved on the rotating shaft 4, a lower fixing rod 52 fixedly connected to the U-shaped plate 1, and an upper fixing rod 53 fixedly connected to the barb 3. The two pins of the torsion spring 51 are respectively installed on the lower fixing rod 52 and the upper fixing rod 53. There is a small gap between the upper fixing rod 53 and the U-shaped plate 1. This setting enables the upper fixing rod 53 to rotate synchronously when the barb 3 rotates. One end of the lower fixing rod 52 far from the U-shaped plate 1 is fixedly connected with a lower limit plate 521;

[0035] When the barb 3 is rotated to open the barb 3, the torsion spring 51 is compressed. Then the barb 3 is released, and under the action of the torsion spring 51, the barb 3 can be driven to reset and close, so that the barb 3 is stuck on the limit rod 2 through the limit groove.

[0036] One end of the limit rod 2 far from one of the frames 6 is fixedly connected with a limit plate 21. When the barb 3 is stuck on the limit rod 2, the barb 3 contacts the limit plate 21.

[0037] After the latch assembly is used, rotate the barb 3 to disengage the barb 3 from the limiting rod 2, and remove the U-shaped plate 1 from the two frames 6. After opening the two frames 6, rotate the barb 3 to open the barb 3, then align the groove formed in the U-shaped plate 1 with the limiting rod 2, insert the U-shaped plate 1 onto one of the frames 6 and make the limiting rod 2 located in the groove formed in the U-shaped plate 1, and then release the barb 3. Under the action of the torsion spring 51, the barb 3 can be driven to reset and close, so that the barb 3 is stuck on the limiting rod 2 through the limiting groove. At this time, under the cooperation of the barb 3 and the limiting rod 2, the U-shaped plate 1 can be tilted and hung on one of the frames 6, and the barb 3 will not fall off under the cooperation of the barb 3 and the limiting rod 2. In this way, there is no need to find a separate place to place the latch assembly, and the loss of the latch assembly can be avoided. When in need of use, the latch assembly can be removed from one of the frames 6.

[0038] An arc-shaped groove is formed at the bottom of one side of the barb 3, and a gap is left between the lower fixing rod 52 and the arc-shaped groove. Such a setting facilitates the rotation of the barb 3.

[0039] A handle 31 is fixedly connected to the top of the other side of the barb 3. Through the arrangement of the handle 31, it is convenient to rotate the barb 3. The user only needs to pinch the handle 31 with the hand to drive the barb 3 to rotate.

[0040] To sum up, the present utility model is through.

[0041] All the technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
