[0032] like Figures 1 to 4 As shown, a U-shaped lock includes a main body 1, as shown Figure 1 As shown, the main body 1 of this embodiment is in a square shape, and a U-shaped through hole 3 is provided on the main body 1. The U-shaped through hole 3 passes through one side of the main body 1 and communicates with the outside. Through the above arrangement, the U-shaped lock buckle of this embodiment does not need to be divided into male and female locks, which is convenient for users to produce.

[0033] like Figure 2 As shown, the widths of the main body 1 and the U-shaped through hole 3 are equal, and one main body 1 can be horizontally inserted into the inside of another main body 1, and the two form two mutually perpendicular intersecting planes. The two main bodies 1 abut against each other. By adopting the above scheme, the two main bodies 1 can be spliced ​​together to form a stable connection state, which is convenient for users to use.

[0034] like Figure 3As shown, the main body 1 is provided with a plug-in connector 2, which includes a U-shaped buckle 21 and an abutment 22 at the bottom of the U-shaped buckle 21. The U-shaped buckle 21 is provided with a U-shaped through hole 3, which passes through one side of the U-shaped buckle 21 and communicates with the outside. The main body 1 and the U-shaped buckle 21 are plugged and abutted against each other through the U-shaped through hole 3. In addition to the plug-in between two main bodies 1, the main body 1 can also be connected with other objects having a U-shaped buckle 21.

[0035] like Figure 3 and 4 As shown, a connecting member 4 is fixedly connected to the bottom of the main body 1 , and the connecting member 4 is sleeved on the outside of the U-shaped buckle 21 , the bottom surface of the connecting member 4 abuts against the top surface of the abutting surface, and the top surface of the connecting member 4 abuts against the bottom surface of the main body 1 .

[0036] The first scheme of this embodiment is to set a through hole 41 on the connecting member 4, and the through hole 41 passes through the top and bottom surfaces of the connecting member 4 to communicate with the outside world. The connecting member 4 is sleeved on the outside of the U-shaped buckle 21 through the through hole 41. Through the above scheme, the connecting member 4 can be stably fixed between the main body 1 and the connector 2.

[0037] During installation, the through hole 41 of the connector 4 is placed against the top surface of the U-shaped buckle 21, the connector 4 falls on the abutment 22 and is sleeved on the outside of the U-shaped buckle 21, and then the main body 1 is inserted into the U-shaped buckle 21. At this time, the upper and lower surfaces of the connector 4 are respectively against the top surface of the abutment 22 and the bottom surface of the main body 1. During disassembly, the U-shaped main body 1 is pulled out from the U-shaped buckle 21, and the connector 4 can be taken out, which is convenient for users to install and take out the connector 4.

Through the above setting, the movement of the connecting member 4 can be limited, and the connecting member 4 can be fixed to the top of the abutment member 22. Through the above scheme setting, it is easy to install and disassemble the connecting member 4.

[0039] like Figure 1 As shown, the two sides of the U-shaped through hole 3 of the utility model are arcuate, and the arcuate design can reduce the friction loss between the main body and the U-shaped buckle 21 during the plugging and unplugging process, thereby extending the service life. In addition, the width of the end of the U-shaped through hole 3 is greater than the width of the middle part. During the insertion process, the main body 1 can first enter the wider end and then gradually transition to the narrower middle part, reducing the resistance and friction during insertion, making it easier for users to plug and fix.
