[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The utility model provides a low temperature box, such as Figures 1 to 4 shown.

[0034] Example 1:

[0035] A low-temperature box includes a box body 1, a cooling chamber 2 is provided inside the box body 1, and a tightening part is installed on both end surfaces of the box body 1. A box cover 3 is provided at the opening of the cooling chamber 2. A plurality of connecting plates 6 are fixedly connected to one end surface of the box cover 3, and a plurality of snap-fit ​​assemblies are installed on the other end surface. The connecting plates 6 and the snap-fit ​​assemblies are respectively connected to the corresponding tightening parts. When the box cover 3 is in a closed state, the box cover 3 will press against the side of the box body 1 under the action of the tightening part, so that the cooling chamber 2 can remain sealed.

[0036] A sealing groove 4 is provided around the opening of the cooling chamber 2 and on the side of the box body 1. A sealing frame 5 that is compatible with the sealing groove 4 is fixedly connected to the box cover 3. When the box cover 3 is in a closed state, the sealing frame 5 will be inserted into the sealing groove 4, thereby improving the sealing between the box cover 3 and the box body 1.

[0037] The tightening portion includes a connecting frame 7, which is fixedly connected to the box body 1, and the opening of the connecting frame 7 faces the box cover 3. A connecting block 8 is connected to the inner wall of the connecting frame 7 through a spring 9. One end of the spring 9 is fixedly connected to the inner wall of the connecting frame 7, and the other end is fixedly connected to the connecting block 8. The spring 9 has a tendency to pull the connecting block 8 toward the inside of the connecting frame 7.

[0038] The connecting plate 6 and the corresponding connecting block 8 are hinged to each other. When the box cover 3 is in the closed state, under the pulling force of the corresponding spring 9, the connection between the connecting plate 6 and the connecting block 8 will be inserted into the interior of the connecting frame 7. At this time, the connecting frame 7 will limit the connecting plate 6, so that the connecting plate 6 cannot rotate. Only when the connection between the connecting plate 6 and the connecting block 8 moves to the interior of the connecting frame 7 can the box cover 3 be rotated. This means that when opening or closing the box cover 3, the box cover 3 must be slid a certain distance along the direction of the connecting frame 7, so that the sealing frame 5 can be better inserted into the interior of the sealing groove 4, or moved out of the interior of the sealing groove 4;

[0039] In addition, when the box cover 3 is in the closed state, the box cover 3 cannot be rotated at will, so that the staff can easily connect the end face of the box cover 3 away from the connecting plate 6 to the box body 1 through the buckle assembly.

[0040] The snap assembly includes a fixed frame 10 and a card frame 11. The fixed frame 10 is "L"-shaped. The fixed frame 10 is fixedly connected to the box cover 3 and is carded with the card frame 11. The card frame 11 is hinged to the corresponding connecting block 8. When the card frame 11 and the fixed frame 10 are carded with each other, under the tension of the corresponding spring 9, the card frame 11 will apply a tightening force to the fixed frame 10, so that the card frame 11 and the fixed frame 10 can be stably maintained in a carded state. Only when the staff pulls the card frame 11 away from the box body 1 to card it with the fixed frame 10, and rotates the card frame 11 away from the box cover 3, can the card frame 11 be disengaged from the fixed frame 10, and the box cover 3 can be opened at this time.

[0041] Example 2:

[0042] On the basis of the first embodiment, in order to further improve the sealing between the box cover 3 and the box body 1, a gasket 12 is fixedly provided on one side wall of the sealing groove 4. The inner end thickness of the gasket 12 is greater than the outer end thickness. Figure 4As shown, one end of the gasket 12 close to the bottom side wall of the sealing groove 4 is the inner end, and the other end is the outer end. The side of the gasket 12 away from the cooling chamber 2 is an inclined surface. The sealing frame 5 is provided with an inclined surface adapted to the gasket 12, and the sealing frame 5 and the gasket 12 are both set to be hollow structures. Under the action of the pressing part, the sealing frame 5 will press against the gasket 12. At this time, the sealing frame 5 and the gasket 12 will both produce a certain deformation, indicating that the sealing frame 5 and the gasket 12 have sufficient pressing force, thereby improving the sealing between the sealing frame 5 and the gasket 12.

[0043] Furthermore, the end of the sealing frame 5 away from the box cover 3 is set to a circular arc surface. Under the action of the pressing force, the circular arc surface will press against the bottom side wall of the sealing groove 4. The circular arc surface will be deformed under the action of this pressing force, so that the sealing frame 5 can be further pressed against the gasket 12, and then the sealing between the sealing frame 5 and the gasket 12 can be further improved.

[0044] Example 3:

[0045] On the basis of Example 2, in order to increase the cooling rate of the workpiece, a support frame 13 is fixedly connected to the inside of the cooling chamber 2, and a gap is left between the support frame 13 and the lower side wall of the cooling chamber 2. The support frame 13 includes multiple support rods 1 and multiple support rods 2. The support rods 1 and the support rods 2 are perpendicular to each other and cross each other to form a grid plate, and the upper side surfaces of the support rods 1 and the support rods 2 are wedge-shaped surfaces. When the workpiece to be cooled is placed on the support frame 13, the contact area between the workpiece and the air inside the cooling chamber 2 can be greatly increased, thereby increasing the cooling rate of the workpiece.

[0046] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
