Description

Inner door seal structure of medical low-temperature storage box

Technical Field

The utility model belongs to the technical field of the box is sealed, a interior door seal structure of medical low temperature preservation case is related to.

Background

The medical cryopreservation box is used for storing some medicines, collected specimens, some vaccines and other storage devices.

The interior door seals is installed on the interior door of medical cryopreservation case, current interior door seals usually includes gasbag and installation foot, the gasbag passes through the installation foot to be installed in the interior door mounting groove of medical cryopreservation case, when closing the interior door, thereby the gasbag keeps room front end surface contact to realize the sealed of box in the case box with medical cryopreservation, nevertheless because the cross sectional shape of current gasbag is oval, the shrinkage deformation volume is little, the compactness of preserving room front end surface contact in gasbag and the medical cryopreservation case box is poor, the sealed effect of box is not good.

Disclosure of Invention

The utility model discloses to the above-mentioned problem that prior art exists, provide an interior door seal structure of medical low temperature preservation case, the utility model aims to solve the technical problem that: how to improve the sealing effect of the box body.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a medical cryopreservation box's interior door seal structure, includes the crossbeam, one side of crossbeam is formed with the installation foot, the opposite side of crossbeam is formed with first gasbag and second gasbag, it is protruding first to have outside convex arc on the first gasbag, it is protruding two to have outside convex arc on the second gasbag.

The installation foot is installed in medical cryopreservation incasement door mounting groove, has outside convex arc protruding one on the first gasbag, has outside convex arc protruding two on the second gasbag, and first gasbag and second gasbag are located the opposite side of crossbeam, make arc protruding one and arc protruding two respectively can with preserve room front end surface contact extrusion contact in the medical cryopreservation incasement box body when the interior door is closed, realized the double sealing to the box to just improved the sealed effect of box.

In the inner door seal structure of the medical low-temperature storage box, the first air bag and the second air bag are arranged adjacently, and the first arc-shaped bulge is connected with the second arc-shaped bulge. First gasbag and the adjacent setting of second gasbag make interior door seal compact structure, and arc arch one links to each other with arc arch two and makes arc arch one and arc arch two press close to with preservation room front end surface extrusion contact position in the medical low temperature preservation case box respectively, have guaranteed the leakproofness to two contact position of preservation room front end surface in the medical low temperature preservation case box to improve the sealed effect of box.

In the inner door seal structure of the medical low-temperature storage box, the maximum distance between the first arc-shaped protrusion and the cross beam is the same as the maximum distance between the second arc-shaped protrusion and the cross beam. When the inner door is closed, the first arc-shaped bulge and the second arc-shaped bulge are in consistent extrusion contact with the surface of the front end of the storage chamber in the medical low-temperature storage box body, so that the double sealing performance of the box body is kept consistent.

In the inner door seal structure of the medical low-temperature preservation box, a limiting block is arranged in the first air bag and connected to the cross beam. The stopper restricts first gasbag shrink volume, when guaranteeing the box leakproofness, when avoiding the inner door to close, and the too violent first gasbag and the transition compression of second gasbag of messenger of exerting oneself influence life.

In the internal door seal structure of the medical low-temperature preservation box, the first air bag and the mounting feet are positioned at two opposite sides of the cross beam. The surface extrusion force of the first air bag and the front end of the storage chamber in the box body of the medical low-temperature storage box is large, and the sealing performance of the inner door seal is improved.

In the interior door seal structure of foretell medical low temperature preservation case, installation foot one side is equipped with barb one, and the opposite side is equipped with barb two. Barb one and barb two prevent that the installation foot from deviating from in medical low temperature preservation incasement door mounting groove, guarantee interior door seal and preserve the fastness of incasement door installation.

In the interior door seal structure of foretell medical cryopreservation case, barb one is one, and barb two is two. The inner door seal is more firmly connected with the inner door of the storage box.

Compared with the prior art, the utility model has the advantages as follows:

the first arc-shaped bulge and the second arc-shaped bulge are respectively in extrusion contact with the surface of the front end of the storage chamber in the medical low-temperature storage box body by closing the inner door, so that double sealing of the box body is realized, and the sealing effect of the box body is improved.
