[0026] As shown in Figure 1 The powder container of the present embodiment includes a box body 10, a door body 20 and a locking structure 30. The box body 10 has a containing space 11 for containing powder, a powder inlet 12 and a powder outlet 13, both of which are in communication with the containing space 11. The door body 20 is arranged at the powder outlet 13 and is hingedly connected with the box body 10. The locking structure 30 includes a locking core 31 and a limiting piece 32. The locking core 31 includes a locking column 311 and a locking disc 312 connected to the inner side of the locking column 311. The locking column 311 is rotatably connected with the door body 20. The limiting piece 32 is arranged in the box body 10. The locking disc 312 has a locking position for stopping the limiting piece 32 and an avoiding position for avoiding the limiting piece 32. The locking disc 312 includes a variable diameter portion 3121 which gradually contracts and extends inward in the direction from the door body 20 to the inside of the containing space 11.

[0027] The technical scheme is applied to the powder container, which comprises a box body 10, a door body 20 and a locking structure 30. The box body 10 has a containing space 11 for containing powder, a powder inlet 12 communicating with the containing space 11 and a powder outlet 13 communicating with the containing space 11. The door body 20 is arranged at the powder outlet 13 and is hingedly connected with the box body 10. The locking structure 30 comprises a locking core 31 and a limiting piece 32 arranged in the box body 10. The locking core 31 comprises a locking column 311 and a locking disc 312. The locking disc 312 is connected to the inner side of the locking column 311 and is rotatably connected with the door body 20. The locking disc 312 has a locking position and an avoiding position. When the locking disc 312 is in the locking position, the locking disc 312 is in abutting engagement with the limiting piece 32. When the locking disc 312 is in the avoiding position, the locking disc 312 avoids the limiting piece 32. The locking disc 312 comprises a variable-diameter portion 3121 which gradually extends inwardly in the direction from the door body 20 to the inside of the containing space 11. Through the above arrangement, the powder can enter the containing space 11 from the powder inlet 12, and the powder in the containing space 11 can flow out from the powder outlet 13. The door body 20 can shield the powder outlet 13 to prevent the powder in the containing space 11 from flowing out. The door body 20 is hingedly connected with the box body 10, so that the door body 20 can move towards the direction close to the box body 10 or move towards the direction away from the box body 10. When the locking column 311 rotates, the locking disc 312 can be driven to rotate, so that the locking disc 312 can move between the locking position and the avoiding position. The variable-diameter portion 3121 gradually extends inwardly in the direction from the door body 20 to the inside of the containing space 11, so that when the containing space 11 is filled with powder, the variable-diameter portion 3121 can be more easily rotated. Therefore, the technical scheme of the embodiment effectively solves the problem in the prior art that when the box body is filled with powder, the lock is not easy to rotate.

[0028] It should be noted that the door body 20 and the box body 10 are connected through a pin shaft.

[0029] As shown in Figure 4 , in the embodiment, the generatrix of the variable-diameter portion 3121 is an inner concave arc line. The above arrangement makes the variable-diameter portion 3121 more easily rotate in the powder.

[0030] As shown in Figure 3 and Figure 4 , in the embodiment, the locking disc 312 further comprises a base disc portion 3122 which is arranged on the side of the variable-diameter portion 3121 facing the door body 20. The diameter of the base disc portion 3122 is equal to the maximum diameter of the variable-diameter portion 3121. The base disc portion 3122 makes the connection between the variable-diameter portion 3121 and the door body 20 more stable.

[0031] As shown in Figure 2 and Figure 3As shown, in this embodiment, the locking plate 312 has an escape notch 3123. When the locking plate 312 is in the escape position, the escape notch 3123 is arranged corresponding to the limiter 32. By providing the escape notch 3123, when the locking plate 312 is in the escape position, the escape notch 3123 can avoid the limiter 32, and then the door body 20 can be opened.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, when the locking plate 312 is in the locked position, the first end of the base plate portion 3122 is engaged with the stopper 32, the second end of the base plate portion 3122 is located above the stopper 32, and the distance between the first end of the base plate portion 3122 and the door body 20 is smaller than the distance between the second end of the base plate portion 3122 and the door body 20. The first end of the base plate portion 3122 is engaged with the stopper 32, so that the stopper 32 can stop the base plate portion 3122 and prevent the door body 20 from opening. When the locking disk 312 is in the locked position, the distance between the first end of the base disk portion 3122 and the door body 20 is smaller than the distance between the second end of the base disk portion 3122 and the door body 20. In this way, the distance between the base disk portion 3122 and the door body 20 gradually increases in the direction from the first end of the base disk portion 3122 to the second end of the base disk portion 3122, which facilitates the rotation of the base disk portion 3122 in the powder.

[0033] like Figure 4 As shown, in this embodiment, the side of the base plate portion 3122 facing the door body 20 is a spiral surface. The above arrangement enables the base plate portion 3122 to rotate more easily in the powder.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, the locking structure 30 further includes a plate 33, which is disposed at the second end of the base disc portion 3122 and is located on the surface of the base disc portion 3122 facing the door body 20. When the locking disc 312 is in the locked position, the plate 33 abuts and cooperates with the limiting member 32. With the above arrangement, when the plate 33 abuts the limiting member 32, the base disc portion 3122 cannot rotate any further, thereby indicating that the locking disc 312 is in the locked position.

[0035] like Figure 1 As shown, in this embodiment, a mounting hole 21 is provided on the door body 20, and the first end of the locking post 311 is rotatably provided in the mounting hole 21. The provision of the mounting hole 21 facilitates the connection between the locking post 311 and the door body 20.

[0036] like Figures 2 to 4 As shown, in this embodiment, the limiting member 32 includes a limiting pin 321 extending along the height direction of the box body 10. The limiting pin 321 has a simple structure and is easy to process.

[0037] In the embodiment, the powder container further comprises a sealing member arranged at the outer edge of the door body 20 and / or the edge of the powder outlet 13.

[0038] The powder container further comprises a sealing member arranged at the outer edge of the door body 20 and / or the edge of the powder outlet 13.

[0039] The sealing member is a sealing strip.

[0040] Compared with a ton bag made by using a weaving process, the powder is particularly inconvenient to use when pouring and receiving, and there is more powder hanging inside and more powder loss. The box body 10 of the embodiment is welded by using 304 food-grade stainless steel plate, and full welding process is used. The powder inlet 12 is arranged at the top of the box body 10 and is used for receiving powder. The powder outlet 13 is arranged at one side of the box body 10 and is used for discharging powder. The door body 20 is in a closed state when powder is filled, and the door body 20 is in an open state when powder is discharged. Meanwhile, four ground corners of the box body 10 are welded and nylon ground corners are arranged.
