Abstract

There is provided an airtight box, comprising a box body and a cover covering the box body to close the box body tightly. The box body is provided with a receiving chamber with an opening which opens upwards and two side walls respectively located on both sides of the receiving chamber. A sliding groove extending longitudinally is provided on an outer side of each side wall. The airtight box is further provided with an opening and locking mechanism slidably connecting the cover and the box body. The opening and locking mechanism is provided with a pushing member slidably fixed in the sliding groove and a connecting rod rotatably fixed on the pushing member and mounted inside the cover. The connecting rod, under an action of the pushing member, presses upwards and drives the cover backwards to expose the receiving chamber to the outside.

First claim

What is claimed is:

1. An airtight box, comprising a box body and a cover covering the box body to close the box body tightly, wherein the box body is provided with a receiving chamber with an opening which opens upwards and two side walls respectively located on both sides of the receiving chamber, and a sliding groove extending longitudinally is provided on an outer side of each side wall; wherein the airtight box is further provided with an opening and locking mechanism slidably connecting the cover and the box body, wherein the opening and locking mechanism is provided with a pushing member slidably fixed in the sliding grooves of the two side walls respectively and a connecting rod rotatably fixed on the pushing member and mounted inside the cover, and the connecting rod, under an action of the pushing member, presses upwards and drives the cover backwards to expose the receiving chamber to the outside; wherein the pushing member is provided with a main body located above one end of the box body, and two hanging walls extending downwards from both ends of the main body respectively, wherein the main body is provided with a pushing hand portion protruding upwards, and the pushing hand portion passes through the cover upwards and is exposed to the outside.

2. The airtight box of claim 1 , wherein the connecting rod is provided with a supporting rod received inside the cover and two ear rods vertically extending from both ends of the supporting rod respectively, wherein each ear rod is mounted on the hanging wall, and when the pushing member moves backwards, the hanging walls pushes the ear rods backwards and the ear rods drive the supporting rod upwards to support the cover upwards.

3. The airtight box of claim 2 , wherein each hanging wall is provided with an inverted L-shaped guide rail groove and a position limiting groove, wherein the position limiting groove vertically extends and passes through the hanging wall, and the guide rail groove longitudinally extends and passes through the hanging wall.

4. The airtight box of claim 3 , wherein the top of the position limiting groove communicates with the front end of the guide rail groove.

5. The airtight box of claim 4 , wherein the opening and locking mechanism further comprises a sliding member capable of sliding in each sliding groove longitudinally, wherein the sliding member is provided with a first pulley mounted in the position limiting groove and a second pulley mounted in the guide rail groove, and the second pulley is capable of rotating counterclockwise around the first pulley.

6. The airtight box of claim 5 , wherein the first pulley is provided with a front orienteering roller capable of sliding in the each sliding groove, a fixed wheel located at an outer side of the front orienteering roller, and a first shaft passing through the axes of the front orienteering roller and of the fixed wheel, wherein an intermediate space is provided between the front orienteering roller and the fixed wheel to form a clamping portion.

7. The airtight box of claim 5 , wherein the second pulley is provided with a driven roller and a shaft cavity passing through the driven roller, wherein an edge of the driven roller is clamped within the clamping portion, and a tail end of the ear rod is received within the shaft cavity.

8. The airtight box of claim 2 , wherein the cover is provided with a box cover and a top cover mounted on the box cover, wherein a position limiting space is provided between the top cover and the box cover to allow the supporting rod to move upwards or downwards.

9. The airtight box of claim 8 , wherein a side of the box cover facing the top cover is provided with several fixing columns protruding upwards and arranged longitudinally to longitudinally limit the supporting rod in the position limiting space.
