DETAILED DESCRIPTION

[0035] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] The utility model provides a fresh-keeping container 100 and a low-temperature fresh-keeping device, which have strong sealing performance, thereby achieving a good fresh-keeping effect.

[0037] like Figures 1 to 7 As shown, according to the fresh-keeping container 100 of the embodiment of the present invention, the fresh-keeping container 100 includes a barrel body 10 , a panel 20 and a bracket 30 .

[0038] Among them, the barrel body 10 has a storage cavity 12 with a front opening 11, the barrel body 10 is provided with a positioning portion 13, the panel 20 is configured to open and cover the opening 11, the bracket 30 includes a main body 31 and a claw 32 connected to the main body 31, the main body 31 rotates to connect the panel 20, and has a locking position and an unlocking position, the claw 32 hooks the positioning portion 13 in the locking position to lock the panel 20 to the barrel body 10, and the claw 32 releases the positioning portion 13 in the unlocking position to release the lock on the panel 20; this can improve the sealing performance of the fresh-keeping container 100, thereby improving the fresh-keeping effect of the fresh-keeping container 100.

[0039] When the storage cavity 12 needs to be opened, the user can drive the bracket 30 to rotate relative to the panel 20 to unlock the panel 20. During this process, the main body 31 of the bracket 30 rotates relative to the panel 20 from a locked position to an unlocked position, and the claw 32 releases the positioning portion 13 of the barrel body 10, thereby releasing the lock on the panel 20. At this time, the panel 20 can open and close the storage cavity 12. When the storage cavity 12 needs to be closed, the user can drive the bracket 30 to rotate relative to the panel 20 to lock the panel 20. During this process, the main body 31 of the bracket 30 rotates relative to the panel 20 from an unlocked position to a locked position, and the claw 32 hooks the positioning portion 13 of the barrel body 10, thereby locking the panel 20 on the barrel body 10. Therefore, according to the fresh-keeping container 100 of the embodiment of the utility model, the sealing performance of the fresh-keeping container 100 is improved by locking and unlocking the panel 20 through the bracket 30, thereby improving the fresh-keeping effect of the fresh-keeping container 100.

[0040] like Figure 1 As shown, in some embodiments of the present invention, the first end of the main body 31 is rotatably connected to the panel 20, and the claw 32 is arranged behind the first end, and the claw 32 is spaced from the first end along the front-to-back direction; such an arrangement can improve the sealing performance of the fresh-keeping container 100, thereby improving the fresh-keeping effect of the fresh-keeping container 100.

[0041] In detail, the barrel body 10 has a storage cavity 12 with a front opening 11, and the panel 20 covers the opening 11 on the front side of the storage cavity 12, thereby sealing the storage cavity 12. Therefore, the first end of the main body 31 can be rotatably connected to the panel 20, and the claw 32 is arranged behind the first end of the main body 31. In this way, when the main body 31 is in the locked position, the claw 32 can hook the positioning portion 13 of the barrel body 10 to prevent the panel 20 from moving forward relative to the barrel body 10 and detaching from the barrel body 10, thereby improving the sealing performance of the fresh-keeping container 100.

[0042] In addition, the claw 32 is spaced apart from the first end of the main body 31 along the front-to-back direction, which can increase the range of motion of the claw 32 and facilitate the claw 32 to better hook and release the positioning portion 13 of the barrel body 10.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the claw 32 extends in the up-down direction at the locking position, and the front side is constructed with an arc-shaped groove 321 that is recessed backward in the middle along the up-down direction; in this way, the locking strength of the bracket 30 to the panel 20 can be increased, thereby improving the sealing performance of the fresh-keeping container 100.

[0044] Optionally, combined Figures 1 to 5When switched to the locked position, the lower end of the claw 32 is connected to the main body 31, and the main body 31 can be rotated upward from the unlocked position to the locked position; during this process, the positioning portion 13 of the barrel body 10 can move along the front side of the claw 32 from the upper end of the claw 32 to the lower end of the claw 32, and is embedded in the arc-shaped groove 321 between the upper and lower ends of the claw 32. The cooperation between the arc-shaped groove 321 and the positioning portion 13 can increase the contact area between the claw 32 and the positioning portion 13, thereby improving the locking strength of the bracket 30 to the panel 20, and further improving the sealing performance of the fresh-keeping container 100. In addition, when switched to the unlocked position, the main body 31 can be rotated downward from the locked position to the unlocked position; during this process, the positioning portion 13 of the barrel body 10 can move along the front side of the claw 32 from the lower end of the claw 32 to the upper end of the claw 32, so as to disengage from the arc-shaped groove 321 of the claw 32, thereby unlocking the panel 20.

[0045] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, an open groove 322 is constructed between the claw 32 and the first end at the end of the bracket 30; it can be understood that when the bracket 30 is switched to the locked position, the positioning portion 13 of the barrel body 10 can be embedded in the open groove 322 at the end of the bracket 30, and when the bracket 30 is switched to the unlocked position, the positioning portion 13 of the barrel body 10 can be disengaged from the open groove 322 at the end of the bracket 30. In this way, through the cooperation between the open groove 322 and the positioning portion 13, the contact area between the claw 32 and the positioning portion 13 can be increased, thereby improving the locking strength of the bracket 30 to the panel 20.

[0046] In addition, in some specific examples of the present invention, the opening groove 322 has a first side surface and a second side surface opposite to each other in the front-to-back direction, and the first side surface and the second side surface extend along the rotation direction of the bracket 30, so as to facilitate the positioning portion 13 to be embedded in and disengaged from the opening groove 322, and the first side surface can be arranged behind the second side surface, and the first side surface is provided with the aforementioned arc-shaped groove 321 to further improve the locking strength of the bracket 30 to the panel 20.

[0047] like Figures 1 to 3 As shown, in some embodiments of the present invention, the fresh-keeping container 100 also includes a handle 40, which is connected to the bracket 30 and is configured to drive the bracket 30 to rotate; it can be understood that when opening and closing the storage cavity 12, the user can hold and flip the handle 40 to drive the bracket 30 to rotate relative to the panel 20, thereby unlocking and locking the panel 20 on the barrel body 10, thereby improving the user's convenience.

[0048] The user drives the bracket 30 to rotate by the handle 40. In order to ensure that the bracket 30 locks and unlocks the panel 20, a high connection strength is required between the bracket 30 and the handle 40. Figures 2 to 4As shown, in some embodiments of the present invention, a positioning seat 41 is provided at the end of the handle 40, a positioning groove 411 is provided on the end face of the positioning seat 41, and a mounting block 313 is provided at the second end of the main body 31, and the mounting block 313 is passed through the positioning groove 411; in this way, the connection strength between the handle 40 and the bracket 30 can be improved, thereby improving the locking strength of the bracket 30 to the panel 20.

[0049] Specifically, the main body 31 has a first end and a second end relative to each other. The first end of the main body 31 is rotatably connected to the panel 20, and the second end of the main body 31 is provided with a mounting block 313. The mounting block 313 can be inserted into the positioning groove 411 of the positioning seat 41 at the end of the handle 40 to improve the connection strength between the handle 40 and the bracket 30.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the positioning groove 411 is set as a non-circular groove, and the mounting block 313 is adapted to the shape of the positioning groove 411; such a setting can facilitate the user to stably drive the bracket 30 through the handle 40; in detail, if the positioning groove 411 is set as a circular groove, when the user drives the handle 40, relative rotation will occur between the handle 40 and the bracket 30, resulting in the user being unable to stably drive the bracket 30 to rotate between the unlocked position and the locked position through the handle 40. Therefore, the positioning groove 411 can be set as a non-circular groove. In this way, when the mounting block 313 is matched with the positioning groove 411 and connected, the structure between the mounting block 313 and the positioning groove 411 is offset, so that the relative position of the handle 40 and the bracket 30 remains unchanged, which is convenient for the user to drive the bracket 30 to rotate through the handle 40 to realize the opening and closing of the storage cavity 12.

[0051] In more detail, the positioning groove 411 is set as a square groove, and the mounting block 313 is set as a square block that is adapted to the shape of the positioning groove 411; in this way, the mounting block 313 can be passed through and installed in the positioning groove 411, and the shapes of the mounting block 313 and the positioning groove 411 are adapted to achieve the limitation between the handle 40 and the bracket 30, thereby limiting the rotation of the handle 40 relative to the bracket 30, so as to improve the user experience.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the sidewall of the positioning groove 411 is provided with a positioning notch 412 , and the mounting block 313 includes a positioning protrusion 314 passing through the positioning notch 412 ; thus, the connection strength between the handle 40 and the bracket 30 can be further improved.

[0053] During assembly, the mounting block 313 of the bracket 30 can be inserted into the positioning groove 411 of the handle 40, and the positioning protrusion 314 of the mounting block 313 can be inserted into the positioning notch 412 on the side wall of the positioning groove 411. By cooperating and limiting the positioning protrusion 314 and the positioning notch 412, the rotation of the handle 40 relative to the bracket 30 can be limited, so as to improve the connection strength between the handle 40 and the bracket 30, which is convenient for the user to stably drive the bracket 30 to rotate.

[0054] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the main body 31 includes a first branch 311 and a second branch 312 .

[0055] Among them, the first branch 311 extends in the up-down direction in the locked position and tilts backward in the top-down direction. The upper end of the first branch 311 is rotated to connect to the panel 20. The second branch 312 extends in the front-to-back direction in the locked position. The rear end of the second branch 312 is connected to the lower end of the first branch 311, and the front end is connected to the handle 40. In this way, the bracket 30 can give way to the panel 20 to avoid structural interference between the bracket 30 and the panel 20.

[0056] It can be understood that when in the locked position, the upper end of the first branch 311 rotates to connect the panel 20 and tilts backward in the top-down direction, while the rear end of the second branch 312 is connected to the lower end of the first branch 311. In this way, a clearance space can be formed between the first branch 311 and the second branch 312. When the bracket 30 is flipped forward to the unlocked position, the panel 20 can be set in the clearance space to avoid structural interference between the bracket 30 and the panel 20, and when the bracket 30 is flipped backward to the unlocked position, the panel 20 can leave the clearance space.

[0057] like Figure 1 As shown, in some embodiments of the present invention, the handle 40 is configured to be a long strip extending in the left-right direction; this can increase the user's gripping area, making it easier for the user to drive the handle 40 to rotate; and can also increase the structure of the handle 40, thereby improving the structural strength of the handle 40.

[0058] Furthermore, the left and right ends of the handle 40 are connected to brackets 30. The bracket 30 on the left side of the handle 40 rotates to connect to the left side of the panel 20, and the bracket 30 on the right side of the handle 40 rotates to connect to the right side of the panel 20. In this way, the rotation stability of the handle 40 can be improved. When the handle 40 is driven to rotate, the brackets 30 on the left and right ends of the handle 40 can disperse the force applied to the handle 40, so that the handle 40 can operate more stably.

[0059] like Figure 1As shown, in some embodiments of the present invention, the bracket 30 is rotatably connected to the middle area of ​​the panel 20 along the up and down direction, and the handle 40 is arranged on the front side of the upper or lower part of the panel 20; this arrangement can ensure the range of movement of the handle 40 and improve the efficiency of use.

[0060] For ease of understanding, the handle 40 is provided on the front side of the lower portion of the panel 20 as an example for explanation:

[0061] It is understood that if the bracket 30 is rotatably connected to the upper region of the panel 20 along the vertical direction, the user will have a large range of motion when driving the bracket 30 to rotate via the handle 40, making it inconvenient for the user to drive the handle 40 to rotate. If the bracket 30 is rotatably connected to the lower region of the panel 20 along the vertical direction, the user will have a small range of motion when driving the bracket 30 via the handle 40, and the distance between the locked and unlocked positions of the bracket 30 is small, which can easily lead to misoperation and affect the use of the fresh-keeping container 100. Therefore, the bracket 30 can be rotatably connected to the middle region of the panel 20 along the vertical direction to ensure the range of motion of the handle 40 and improve the efficiency of use.

[0062] It should be explained that the bracket 30 is rotatably connected to the middle area of ​​the panel 20 along the up and down directions. It can be understood that the rotation connection point between the bracket 30 and the panel 20 is closer to the middle of the panel 20 than the upper or lower part of the panel 20.

[0063] like Figure 1 As shown, in some embodiments of the present invention, the positioning portion 13 is set to a cylindrical shape or a roller structure. Such a setting can facilitate the claw 32 to hook the positioning portion 13 and release the positioning portion 13; it can be understood that the positioning portion 13 is set to a cylindrical shape, and the claw 32 can hook the positioning portion 13 along the outer circumferential surface of the positioning portion 13, or release the positioning portion 13, thereby improving the locking efficiency and reducing structural wear; in addition, the positioning portion 13 is set to a roller structure, and the claw 32 can roll relative to the positioning portion 13, thereby facilitating the claw 32 to hook the positioning portion 13 or release the positioning portion 13, thereby improving the locking efficiency and reducing structural wear.

[0064] In some embodiments of the present invention, the bracket 30 is configured as an integrally formed plastic or metal member, which can improve the structural strength of the bracket 30 and thus improve the locking stability of the bracket 30 to the panel 20 .

[0065] In some embodiments of the present invention, the bracket 30 is configured as an integrally formed metal part, and the thickness of the bracket 30 is greater than or equal to 2 mm and less than or equal to 5 mm, which can take into account the structural strength of the bracket 30 and the cost of the bracket 30. The thickness of the bracket 30 can be 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, etc.

[0066] like Figure 4As shown, in some embodiments of the present invention, the bracket 30 is configured as an integrally molded plastic part, and the bracket 30 includes a base plate and reinforcing ribs, and the reinforcing ribs are connected to the surface of the base plate. In this way, by setting the reinforcing ribs, the structural strength of the bracket 30 can be improved, thereby improving the locking stability of the bracket 30 to the panel 20, and further improving the sealing performance of the fresh-keeping container 100.

[0067] Furthermore, the thickness of the bracket 30 is not less than 6 mm and not more than 7 mm, which can take into account both the structural strength and cost of the bracket 30. The thickness of the bracket 30 can be 6 mm, 6.2 mm, 6.5 mm, 6.7 mm, 7 mm, etc. In addition, the thickness of the bottom plate is not less than 2 mm and not more than 4 mm, which can take into account both the structural strength and cost of the bracket 30. The thickness of the bracket 30 can be 2 mm, 2.5 mm, 3 mm, 4 mm, etc.

[0068] like Figure 6 As shown, in some embodiments of the present invention, the fresh-keeping container 100 further includes a drawer 50. The drawer 50 is disposed in the storage cavity 12 and is connected to the panel 20. A storage cavity 51 is provided in the drawer 50. This configuration makes it easier for users to take items in and out. During use, the user can use the handle 40 to drive the panel 20 to pull the drawer 50 out of the storage cavity 12. At this time, the items in the storage cavity 51 can be taken out along with the drawer 50, making it easier for the user to take them out. After the user places the items in the storage cavity 51, the user can use the handle 40 to drive the panel 20 to push the drawer 50 back into the storage cavity 12. At this time, the items in the storage cavity 51 can be brought in along with the drawer 50, improving user convenience.

[0069] like Figure 7 As shown, in some embodiments of the present invention, the barrel body 10 is provided with an exhaust port 14 for connecting to an exhaust device, and the exhaust port 14 is connected to the storage cavity 12. The exhaust port 14 can be connected to an external exhaust device. The exhaust device extracts the gas in the storage cavity 12 to form a low-pressure environment in the storage cavity 12. At this time, the bacteria and other organisms in the storage cavity 12 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 12; optionally, a vacuum environment can be created in the storage cavity 12 through the exhaust port 14 to further improve the preservation effect of the fresh-keeping container 100.

[0070] like Figure 7 As shown, in some embodiments of the present invention, the fresh-keeping container 100 also includes an exhaust component 60, which is connected to the storage cavity 12. The exhaust component 60 can extract the gas in the storage cavity 12 to form a low-pressure environment in the storage cavity 12. At this time, the bacteria and other organisms in the storage cavity 12 are less active in the low-pressure environment, thereby preserving the items in the storage cavity 12.

[0071] like Figures 1 to 7 As shown, the low-temperature fresh-keeping device according to an embodiment of the present invention includes a body, a refrigeration device and the fresh-keeping container 100 in the above embodiment.

[0072] Among them, the body is provided with a refrigeration compartment, the refrigeration device is provided in the body for cooling the refrigeration compartment, and the fresh-keeping container 100 is provided in the refrigeration compartment. By applying the aforementioned fresh-keeping container 100, the sealing performance of the low-temperature fresh-keeping equipment can be improved, thereby improving the fresh-keeping effect of the low-temperature fresh-keeping equipment.

[0073] Specifically, the fresh-keeping container 100 is placed in a refrigeration room and cooled by a refrigeration device in the refrigeration room, so that the fresh-keeping container 100 is in a low-temperature environment. In a low-temperature environment, biological activities such as bacteria are reduced, thereby achieving a low-temperature preservation function.

[0074] When using the fresh-keeping container 100, the user can hold and flip the handle 40 to drive the bracket 30 to rotate from the locked position to the unlocked position. At this time, the panel 20 is unlocked, and the user can use the handle 40 to drive the panel 20 to open the storage cavity 12. Then, the user can use the handle 40 to drive the panel 20 to close the storage cavity 12 and drive the bracket 30 to rotate from the unlocked position to the locked position. At this time, the panel 20 is locked.

[0075] In the above process, the bracket 30 includes a main body 31 and a claw 32 connected to the main body 31. The main body 31 rotates to connect the panel 20 to switch between a locked position and an unlocked position. When the bracket 30 switches to the locked position, the positioning portion 13 of the barrel body 10 can be embedded in the open groove 322 between the claw 32 and the first end of the main body 31, and engage with the arc-shaped groove 321 on the first side of the opening groove 322 to limit the panel 20 from detaching forward relative to the barrel body 10, thereby improving the sealing performance of the fresh-keeping container 100.
