[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are an important condition for scientific and technological progress. They are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. They can be said to be the eyes of chemists. In the daily work of factories, schools, hospitals and research institutes, chemical reagents are indispensable. Therefore, the storage equipment of chemical reagents is very important to current chemical research.

[0003] At present, storage devices for storing chemical reagents mainly rely on the reaction force of a spring to drive a clamping block to clamp the chemical reagents, thereby preventing the reagents from shaking during movement and ensuring normal storage of the reagents. However, in the existing technology, the cover cannot be firmly locked with the box body, and gaps are prone to appear, making it easy for chemical reagents to be stored and transported to be overturned. Chemical reagents stored in partially open areas will directly contact the air and be contaminated, which directly affects the normal storage of the reagents. Utility Model Content

[0004] The utility model provides a locking and sealing device for reagent storage equipment, which solves the problem that the box body of the existing storage equipment cannot be locked, and the chemical reagents stored in the partially opened part are directly exposed to the air, causing the reagents to be contaminated and affecting the normal storage of the reagents.

[0005] The technical solution of the utility model is: a locking and sealing device for reagent storage equipment, characterized in that: it includes a base, a card seat and a fixed seat, the base is fixedly installed on the box body, a rotating shaft is installed in the base, side panels are installed at both ends of the rotating shaft, the fixed seat is installed in the other end of the two side panels, the card seat is fixedly installed on the box cover, and the bottom of the fixed seat is connected to the top of the card seat through a locking mechanism.

DETAILED DESCRIPTION

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0017] like Figure 1-3 As shown, a locking and sealing device for a reagent storage device is characterized in that it includes a base 108, a card seat 109 and a fixed seat 112, the base 108 is fixedly installed on the box body 101, a rotating shaft 110 is installed in the base 108, side panels 111 are installed at both ends of the rotating shaft 110, the fixed seat 112 is installed in the other end of the two side panels 111, the card seat 109 is fixedly installed on the box cover 102, and the bottom of the fixed seat 112 is connected to the top of the card seat 109 through a locking mechanism.

[0018] The locking mechanism includes a locking bolt 113 and a frosting plate 114 . A threaded hole 124 is provided in the fixing seat 112 . The locking bolt 113 is connected to the threaded hole 124 . The frosting plate 114 is connected to the bottom of the locking bolt 113 and is pressed against the top of the holder 109 .

[0019] The locking mechanism also includes a limit spring 115 and a frosted ring 116. A accommodating cavity 121 is provided in the fixing seat 112. The limit spring 115 is installed in the accommodating cavity 121. The bottom of the limit spring 115 is connected to the frosted ring 116. The bottom of the frosted ring 116 is in contact with the clamping seat 109. The frosted ring 116 is used for preliminary fixation.

[0020] The frosting ring 116 is sleeved on the outer side of the frosting plate 114 , and a gap is left between the frosting plate 114 and the frosting ring 116 .

[0021] A sealing assembly is provided on the inner wall of the box body 101, which includes an inner right-angle plate 118, a square plate 119 and a sealing gasket 120. The inner right-angle plate 118 is installed around the inner top of the box body 101, and a sealing gasket 120 is provided at the right-angle mouth of the inner right-angle plate 118. The square plate 119 is installed around the inner side of the box cover 102, and the square plate 119 rests on the sealing gasket 120. When closed, the gap between the inner right-angle plate 118 and the square plate 119 is filled by the sealing gasket 120 to seal the interior of the device.

[0022] Anti-collision corners 201 are installed at the four outer corners of the box body 101 to avoid collision.

[0023] When the box cover 102 needs to be locked, the fixing seat 112 is flipped. At this time, the rotating shaft 110 in the base 108 rotates in the lifting direction, so that the side panel 111 rotates around the base 108 with the assistance of the rotating shaft 110, and the fixing seat 112 is lifted and flipped along with the side panel 111. When the side panel 111 is perpendicular to the base 108, the side wall of the side panel 111 is against the box body 101, and the rotating shaft 110 stops rotating. When flipping, the rotating shaft 110 supports the flipping of the side panel 111. After flipping, the frosted ring 116 is pushed upward to compress the limit spring 115. When the fixing seat 112 is located just above the card seat 109, the frosted ring 116 is released. Under the reaction force of the limit spring 115, the frosted ring 116 is pressed against the top of the card seat 109 to avoid The fixing seat 112 slides down, and then the locking bolt 113 is rotated to make the locking bolt 113 move downward in the threaded hole 124 until the locking bolt 113 cannot rotate. At this time, the frosted plate 114 at the bottom of the locking bolt 113 is tightly fitted with the top of the card seat 109, and the box cover 102 is locked on the box body 101. The sealing gasket 120 in the box body 101 blocks the space between the inner right-angle plate 118 and the square plate 119, effectively improving the sealing inside the box body 101, avoiding external factors from affecting the reagents, and ensuring the normal storage of the reagents. The anti-collision angle 201 outside the box body 101 effectively protects the box body 101, and can effectively provide buffering when the storage device falls, while avoiding bumps and extending the service life of the box body 101.
