Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the utility model provides a sample storage device for food safety inspection, include protective housing 1 and rolling disc 2 for the cylinder structure, be provided with the storage disc 3 that is used for depositing the sample in protective housing 1, and be connected with through screw rotation in protective housing 1 open-ended one side and be used for carrying out the fixed plate 4 that fixes storage disc 3 position, rolling disc 2 runs through protective housing 1 and sets up the central point department of putting of keeping away from fixed plate 4 one side at storage disc 3, cross slot 10 has been seted up to the central point department of putting of storage disc 3, and rolling disc 2 drives storage disc 3 through the gomphosis with cross slot 10 and rotates, set up a plurality of storage chamber 5 about rolling disc 2 the central axis annular array setting on storage disc 3, and be provided with the evacuation subassembly 6 that is used for the evacuation of storage chamber 5 on protective housing 1.

The rolling disc 2 can be detached, and during use, the connection with the storage disc 3 can be realized through the embedding with the cross groove 10, further, the rotation of the storage disc 3 can be driven by rotating the rolling disc 2, and the storage disc 3 can rotate to enable the storage cavities 5 to move to the positions corresponding to the vacuumizing assembly 6, so that a user can conveniently perform lofting, sampling or vacuumizing through the vacuumizing assembly 6.

The fixed plate 4 is used for extruding the storage disc 3, so that the storage disc and the protective shell 1 are tightly attached to each other, the sealing performance of the storage cavity 5 is further ensured, meanwhile, a user can replace the appropriate storage disc 3 according to the actual situation in the actual use process, and the applicability of the storage disc is stronger.

The opening of storage chamber 5 sets up for fixed plate 4 dorsad, and is provided with on storage disc 3 around the 5 open-ended sealing rubber strip 7 in storage chamber, and sealing strip 7 is used for sealing storage chamber 5 to avoid storage chamber 5 after the evacuation can have the problem of gas leakage, and its cooperation rotation fixed plate 4 extrudees storage disc 3 simultaneously, thereby can further its sealed effect of improvement.

In addition, the storage disc 3, the rotating disc 2 and the protective shell 1 are coaxially arranged, so that the problem that the storage disc 3 is difficult to drive to rotate through the rotating disc 2 in the using process can be avoided.

The vacuumizing assembly 6 comprises a sampling port 601 which is arranged on the protective shell 1 and is opposite to the opening of the storage cavity 5, a sealing column 602 is arranged in the sampling port 601 in a plugging manner, a fixing block 603 is arranged in the sealing column 602, a piston block 605 which is driven by a push rod 604 is arranged on one side, far away from the sampling port 601, of the fixing block 603, a plurality of through holes 606 are formed in the piston block 605 and the fixing block 603, and a control ball 607 which is used for sealing or opening the through holes 606 according to the movement direction of gas is arranged in the through holes 606.

The principle of the device is similar to that of a hydraulic rod, the space of the storage cavity 5 is set to be a first cavity, the space between the piston block 605 and the fixed block 603 is set to be a second cavity, namely, when the device is vacuumized, the piston block 605 is pulled to move through the push rod 604, the air pressure in the second cavity is smaller than the external air pressure, the control ball 607 can seal the through hole 606 on the piston block 605 under the action of the external air pressure, so that the air in the first cavity can be pumped into the second cavity, the through hole 606 on the fixed block 603 cannot be blocked because the air moves along the control ball 607, further, when the piston block 605 is pulled to move towards the fixed block 603 through the push rod 604, the principle is opposite to that of pumping the air in the first cavity, the air in the second cavity can be normally discharged, and the storage cavity 5 can be vacuumized through cyclic reciprocation.

A plurality of annular grooves 8 which are coaxially arranged are formed in one side, relatively attached to the storage disc 3, of the fixing plate 4, a plurality of rollers 9 are arranged in the annular grooves 8, when the storage disc 3 rotates, the rollers 9 can move in the annular grooves 8, friction between the fixing plate 4 and the storage disc 3 can be reduced through the rollers 9, and the abrasion of the fixing plate 4 can be effectively reduced.
