When the first and second door pieces 42, 43 are opened, as shown in Figure 4, the airtight plate 46 is restricted by the door opening top plate 44 to rotate, and pushes the first connecting rod 23 to cause the second The connecting rod 24 rotates together. When the torque of the second connecting rod 24 exceeds the apex of the first elastic element 25, that is, the first and second ends 251, 252 and the second fixed end 241 are in the same straight line, so that The first elastic element 25 generates a pulling force to make the airtight plate 46 automatically rotate to complete the open state, as shown in Figure 5; and the third and fourth connecting rods 27, 28 are also simultaneously affected by the first and second The connecting rods 23 and 24 are driven by the second elastic element 291 to make the latching rod 29 rotate counterclockwise, so that the latching portion 292 is latched to the push rod 26, and the second connecting rod The rod 24 is locked, so that the airtight plate 46 is locked and cannot be pivoted.

When you want to close the first and second door pieces 42, 43, as shown in Figure 6, the extension rod portion 293 is pushed by the door closing top plate 45 to release the latching portion 292 to the push rod 26 and airtight The locking of the plate 46 allows the push rod 26 to rotate under the restriction of the door closing top plate 45, and push the second link 24 to cause the first link 23 to rotate together. When the second link 24 The torque exceeds the apex of the first elastic element 25, causing the first elastic element 25 to generate a pulling force to make the airtight plate 46 automatically rotate to complete the closed state, as shown in FIG. 3.

The airtight plate body 46 of this creation can provide better airtight effect of the first and second airtight strips 421, 431, and because of the good airtight effect, it can isolate the air circulation inside and outside, and can prevent moisture from entering the cabinet. Used as a moisture-proof cabinet; and when the first and second doors 42, 43 are opened, the airtight panel 46 will leave the main body 41 of the cabinet along with the first door 42, and will not be blocked by the opening 411 of the cabinet. In this way, it is necessary to keep the article from being placed in and out of the main body, and the locking structure can be used to lock the push rod 26 so that the airtight plate 46 can be locked and cannot be pivoted and rebounded.

In summary, this creation provides a better and feasible automatic assignment structure improvement, and a new patent application is submitted in accordance with the law; the technical content and technical features of this creation have been disclosed above, but those familiar with this technology may still be based on The disclosure of this creation makes various substitutions and modifications that do not deviate from the creative spirit of this case. Therefore, the scope of protection of this creation should not be limited to those disclosed in the embodiments, but should include various replacements and modifications that do not deviate from this creation, and are covered by the following patent application scope.
