[0027] As Figure 1 shown, the locking device of this embodiment includes: a connecting member 10, an abutting and locking member 20, and an operating member 30. The first end of the connecting member 10 is connected to the container body 2 of the container 1. The abutting and locking member 20 is movably disposed on the connecting member 10 along the extending direction of the connecting member 10. The abutting and locking member 20 includes a first abutting rod 21 and a second abutting rod 22. The abutting and locking member 20 has a locking position and an unlocking position. When the abutting and locking member 20 is in the locking position, the first abutting rod 21 is in abutting cooperation with the container body 2, and the second abutting rod 22 is in abutting cooperation with the door body 3 of the container 1. The operating member 30 is adjustably disposed on the connecting member 10 and can be in driving cooperation with the abutting and locking member 20 to switch the abutting and locking member 20 from the unlocking position to the locking position and maintain it in the locking position.

[0028] Applying the technical solution of this embodiment, the first end of the connecting member 10 is connected to the container body 2 of the container 1. The abutting and locking member 20 is arranged on the connecting member 10 and is movably arranged along the extending direction of the connecting member 10. The abutting and locking member 20 includes a first abutting rod 21 and a second abutting rod 22. The abutting and locking member 20 has a locking position and an unlocking position. When the abutting and locking member 20 is in the locking position, the first abutting rod 21 is in abutting cooperation with the container body 2, and the second abutting rod 22 is in abutting cooperation with the door body 3 of the container 1. The operating member 30 is adjustably arranged on the connecting member 10, and the operating member 30 can be in driving cooperation with the abutting and locking member 20 so that the abutting and locking member 20 can be switched from the unlocking position to the locking position and remain in the locking position. Through the above arrangement, when the operating member 30 is adjusted on the connecting member 10, it can drive the abutting and locking member 20 to move, so that the abutting and locking member 20 can drive the first abutting rod 21 and the second abutting rod 22 to move, so that the first abutting rod 21 is in abutting cooperation with the container body 2 and the second abutting rod 22 is in abutting cooperation with the door body 3, so that the door body 3 can be stably attached to the container body 2. The operating member 30 can also keep the abutting and locking member 20 in the locking position, that is, the first abutting rod 21 can keep abutting against the container body 2, and the second abutting rod 22 can abut against the door body 3, avoiding the separation of the door body 3 from the container body 2, that is, avoiding the problem that the tank body and the tank door may be separated in the prior art. Therefore, the technical solution of this embodiment effectively solves the problem that the tank body and the tank door of the premixing tank in the related art may be separated during use.

[0029] As Figure 1 and Figure 2 shown, in this embodiment, the abutting and locking member 20 further includes a connecting rod 23 connected between the first abutting rod 21 and the second abutting rod 22. The operating member 30 is in driving cooperation with the connecting rod 23, and both the first abutting rod 21 and the second abutting rod 22 are arranged at an angle with the connecting rod 23. The operating member 30 can drive the connecting rod 23 to move, and then the connecting rod 23 can drive the first abutting rod 21 and the second abutting rod 22 to move, so that the first abutting rod 21 can abut against the container body 2 and the second abutting rod 22 can abut against the door body 3. Both the first abutting rod 21 and the second abutting rod 22 are arranged at an angle with the connecting rod 23, which is convenient for the first abutting rod 21 to abut against the container body 2 and also convenient for the second abutting rod 22 to abut against the door body 3.

[0030] It should be noted that the first abutting rod 21 is perpendicularly arranged with the connecting rod 23. The second abutting rod 22 is perpendicularly arranged with the connecting rod 23. This makes the abutting of the first abutting rod 21 against the container body 2 more stable and also makes the abutting of the second abutting rod 22 against the door body 3 more stable.

[0031] As Figure 1As shown, in this embodiment, the connecting member 10 includes a connecting shaft 11. A threaded hole 31 is provided on the operating member 30, and an external thread is provided on the connecting shaft 11. The external thread is in threaded engagement with the threaded hole 31. The operating member 30 and the connecting shaft 11 are in threaded engagement, which facilitates the movement of the operating member 30 on the connecting shaft 11. Also, when the operating member 30 is not under force, there is no relative movement between the operating member 30 and the connecting shaft 11, so that the abutting locking member 20 can be maintained in the locking position.

[0032] The operating member 30 includes an operating plate, and the threaded hole 31 is provided in the middle of the operating plate. The operating plate includes a first plate body, a second plate body, and a connecting block connecting the first plate body and the second plate body. The threaded hole 31 is provided on the connecting block. The distance between the end of the first plate body away from the connecting block and the connecting rod 23 is greater than the distance between the end of the first plate body close to the connecting block and the connecting rod 23. The first plate body and the second plate body are symmetrically arranged about the axis of the connecting shaft 11. There is a preset angle between the axis of the first plate body and the axis of the second plate body, and the preset angle is between 90° and 135°. Specifically, it can be 90°, 110°, 120°, 130°, or 135°.

[0033] As Figures 1 to 3 shown, in this embodiment, the distance between the end of the first abutting rod 21 facing the container body 2 and the connecting rod 23 is greater than or equal to the distance between the end of the second abutting rod 22 facing the container body 2 and the connecting rod 23. The above setting enables the first abutting rod 21 to abut against the container body 2 more effectively, and also enables the second abutting rod 22 to abut against the door body 3 more effectively.

[0034] As Figure 5 shown, the distance between the end of the first abutting rod 21 facing the container body 2 and the connecting rod 23 is the first distance, and the distance between the end of the second abutting rod 22 facing the container body 2 and the connecting rod 23 is the second distance. When the first distance is greater than the second distance, the difference between the first distance and the second distance is equal to the distance between the side of the door body 3 away from the container body 2 and the container body 2, so that the abutting locking member 20 can effectively lock the door body 3 and also make the force on the abutting locking member 20 more uniform.

[0035] It should be noted that the first abutting rod 21 includes a connecting section and an abutting section. The connecting section is connected to the first end of the connecting rod 23, and the abutting section is movably arranged in the connecting section. The abutting section is in abutting cooperation with the container body 2.

[0036] As Figure 3As shown, an avoidance hole is provided at one end of the connecting section away from the container body 2. The first abutting rod 21 further includes a driving section. A guiding space communicating with the outside of the connecting section is provided inside the connecting section. The first end of the abutting section is movably arranged in the guiding space along the extending direction of the axis of the connecting shaft. The cross-section of the guiding space is polygonal. A communication hole is provided at one end of the abutting section away from the container body 2. The first end of the driving section is in threaded cooperation with the communication hole, and the second end of the driving section is the driving end.

[0037] As Figure 3 and Figure 4 shown, the abutting locking member 20 further includes a first folding plate and a limiting plate. The first folding plate is arranged at one end of the connecting section away from the container body 2. The limiting plate is connected to the driving section. A limiting space is formed between the first folding plate and the connecting section. The limiting plate is arranged in the limiting space. In this way, when the driving section rotates, the relative position between the driving section and the connecting section will not change, and thus the driving section can drive the abutting section to move in the guiding space.

[0038] As Figure 3 shown, the second abutting rod 22 has the same structure as the first abutting rod 21. The end of the abutting section in the first abutting rod 21 facing the container body 2 is the end of the first abutting rod 21 facing the container body 2. The end of the abutting section in the second abutting rod 22 facing the container body 2 is the end of the second abutting rod 22 facing the container body 2.

[0039] As Figure 3 shown, when the side of the door body 3 away from the inside of the container body 2 is flush with the outer surface of the container body 2, rotate the driving section in the second abutting rod 22 and rotate the driving section in the first abutting rod 21 so that the end of the abutting section in the first abutting rod 21 facing the container body 2 is flush with the end of the abutting section in the second abutting rod 22 facing the container body 2, that is, make the first distance equal to the second distance. In this way, the abutting locking member 20 can adapt to different containers 1, that is, adapt to containers 1 with different distances between the side of the door body 3 away from the inside of the container body 2 and the outer surface of the container body 2, improving the versatility of the abutting locking member 20.

[0040] As Figure 2 shown, in this embodiment, an installation through hole 231 is provided on the connecting rod 23. The connecting shaft 11 is inserted into the installation through hole 231. The diameter of the installation through hole 231 is larger than the outer diameter of the connecting shaft 11. In this way, the connecting rod 23 can rotate relative to the connecting shaft 11, that is, it is convenient for the abutting locking member 20 to rotate relative to the connecting shaft 11, so that the abutting locking member 20 can rotate to avoid the door body 3, facilitating the opening of the door body 3.

[0041] As Figure 1 and Figure 2As shown, in this embodiment, the locking device further includes a mounting member 40 and an elastic support member 50. The mounting member 40 is disposed on the container body 2, the connecting shaft 11 is connected to the mounting member 40, and the elastic support member 50 is disposed between the mounting member 40 and the connecting rod 23. The provision of the mounting member 40 facilitates the connection between the connecting shaft 11 and the container body 2. When the operating member 30 moves from the locked position to the unlocked position, the elastic support member 50 can drive the abutting locking member 20 to move away from the mounting member 40, and thus the abutting locking member 20 can be disengaged from both the container body 2 and the door body 3, facilitating the opening of the door body 3.

[0042] As Figure 2 shown, in this embodiment, the mounting member 40 includes a first mounting plate 41 and a second mounting plate 42. One end of the connecting shaft 11 close to the container body 2 is rotatably connected between the first mounting plate 41 and the second mounting plate 42. The connecting shaft 11 can be connected to the container body 2 through the first mounting plate 41 and the second mounting plate 42. One end of the connecting shaft 11 close to the container body 2 is rotatably connected between the first mounting plate 41 and the second mounting plate 42, enabling the connecting shaft 11 to rotate relative to the first mounting plate 41 and the second mounting plate 42, and thus the connecting shaft 11 can rotate relative to the container body 2 and the door body 3.

[0043] It should be noted that the mounting member 40 further includes a connecting plate connected between the first mounting plate 41 and the second mounting plate 42. The first mounting plate 41 and the second mounting plate 42 are spaced apart on one side of the connecting plate away from the container body 2, and the connecting plate is connected to the container body 2. Alternatively, the connecting plate and the container body 2 can be an integral structure. One end of the connecting shaft 11 close to the container body 2 is provided with a cylinder, and the cylinder is connected to the first mounting plate 41 and the second mounting plate 42 through a shaft body. The cylinder is provided with a mounting hole, the middle part of the shaft body is disposed in the mounting hole, the first end of the shaft body is connected to the first mounting plate 41, and the second end of the shaft body is connected to the second mounting plate 42.

[0044] As Figure 2 shown, in this embodiment, the elastic support member 50 includes a gasket 51 and a spring 52. The spring 52 is disposed between the gasket 51 and the connecting rod 23, and one side of the gasket 51 away from the connecting rod 23 is in abutting cooperation with the mounting member 40. The gasket 51 can support the spring 52, facilitating the compression or release of the spring 52. The spring 52 can apply an elastic force to the abutting locking member 20, enabling the abutting locking member 20 to move away from the mounting member 40. The spring 52 can also play a role in preventing loosening, avoiding the operating member 30 moving away from the container body 2 when the abutting locking member 20 is in the locked position.

[0045] As Figure 2 and Figure 3As shown, in this embodiment, the locking device further includes a stopper 60, and the stopper 60 is arranged at one end of the connecting member 10 away from the container body 2. The stopper 60 can prevent the operating member 30 from falling off the connecting shaft 11.

[0046] As Figure 5 shown, the container of this embodiment includes a container body 2, a door 3 that is openably and closably arranged on the container body 2, and a locking device. The locking device is arranged between the container body 2 and the door 3, and the locking device is the above-mentioned locking device. The above-mentioned locking device enables the door 3 to be stably attached to the container body 2, thereby avoiding the separation of the door 3 from the container body 2 due to the loosening of the fasteners connecting the container body 2 and the door 3 caused by the vibration of the container body 2 during the use of the container 1. The container 1 with the above-mentioned locking device also has the above-mentioned advantages.

[0047] As Figure 5 shown, a plurality of recesses are arranged on the door 3, and a plurality of locking devices are included. The plurality of recesses are arranged in one-to-one correspondence with the plurality of locking devices, and a part of the structure of the locking device is located in the recesses, so that the plurality of locking devices and the door 3 can occupy less space, and thus more locking devices can be arranged within the limited space on the outer surface of the container body 2 to ensure the locking effect of the door.

[0048] As Figure 5 shown, the container 1 further includes a connection structure, and the connection structure includes a first connection plate and a connection seat. The container body 2 includes a first side wall, a second side wall, a third side wall, and a fourth side wall arranged in sequence. The first side wall is connected between the second side wall and the fourth side wall, and the first side wall and the third side wall are arranged opposite to each other. The door 3 is installed on the first side wall, the connection seat is arranged on the second side wall, and the first connection plate is connected to the door 3. The first connection plate is hingedly connected to the connection seat.

[0049] As Figure 5 shown, the connection structure further includes a second connection plate, and the second connection plate is arranged on the side of the door 3 away from the first side wall. The first connection plate is connected to the second connection plate. A connection space is arranged on the connection seat, and the second connection plate is inserted into the connection space and is hingedly connected to the connection seat.

[0050] As Figure 5 shown, there are two connection structures, and the two connection structures are arranged at intervals along the height direction of the container body. The connection structure located above is the first connection structure, and the connection structure located below is the second connection structure. The first connection plate of the first connection structure is arranged between the second connection plate of the first connection structure and the second connection plate of the second connection structure. The first connection plate of the second connection structure is arranged between the second connection plate of the first connection structure and the second connection plate of the second connection structure. This makes the force of the two connection structures more reasonable.

[0051] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0052] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the drawings for the device. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0053] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statement, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0054] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
