Box door structure and low-temperature freezer

Abstract

The invention provides a box door structure and a low-temperature freezer, and relates to the technical field of low-temperature freezing equipment. The box door structure comprises a door frame, a box door and a limiting piece, wherein the box door is movably connected with the door frame; the box door comprises a box door body and a sealing piece; the sealing piece is connected with the box door body and suitable for abutting against the door frame in the door closing state; and the limiting piece is connected with the door frame or the box door body and is suitable for preventing the box door body from being sucked inwards in the door closing state. According to the box door structure and the low-temperature freezer provided by the invention, the sealing piece can seal a gap between the box door body and the door frame, so that a heat preservation performance of the low-temperature freezer is improved; and the limiting piece can prevent the box door body from extruding the sealing piece inwards under the action of the internal and external pressure difference, so that the adsorption force of the sealing piece and the door frame can be reduced, the box door body and the door frame can be prevented from being directly contacted and mutually adsorbed, the overall adsorption force of the box door and the door frame is reduced, the box door of the low-temperature freezer is more convenient to open, and the embodied and tangible interaction of a user is improved.

Description

technical field [0001] The invention relates to the technical field of low-temperature freezing equipment, in particular to a box door structure and a low-temperature freezing box. Background technique [0002] Low-temperature freezer is a storage device for storing plasma, reagents, samples and other medical materials. The storage temperature is usually below -25°C. This type of product pays great attention to the insulation performance of the equipment, and often adopts a fully sealed design to avoid heat transfer with the outside world. internal temperature. The full-seal design is usually provided with an elastic seal on the door, and a seal groove is arranged on the door frame. When the door is closed, the seal of the low-temperature freezer is realized by the cooperation of the seal and the seal groove. [0003] When storing large-volume frozen samples, users usually need to use such products with a large single-chamber volume (for example, more than 200L). It will b...
