Abstract

The invention discloses an automatic air pressure balancing door handle of a low-temperature cabinet. The door handle comprises a door handle shell which is provided with a handheld part, and lifting and pulling parts are connected to the two ends of the handheld part correspondingly. The door handle shell is in an n shape and is of a central symmetry structure. A door handle movable part is arranged on the inner side of the handheld part of the door handle shell, and springs are arranged between the handheld part and the door handle movable part of the door handle shell. The door handle movable part is also in an n shape, a first connecting rod and a second connecting rod are sequentially and perpendicularly connected to each of the two ends of the door handle movable part, and each first connecting rod and the corresponding second connecting rod are movably connected. A first connecting rod supporting column is clamped to the right side of each first connecting rod and the inner side of the door handle shell, a second connecting rod supporting column is clamped to the left side of each second connecting rod and the inner side of the door handle shell, and the second connecting rods are perpendicularly connected with pull rods. The invention further discloses a door which comprises the automatic air pressure balancing door handle of the low-temperature cabinet. The automatic air pressure balancing door handle of the low-temperature cabinet is simple in structure, and after the door handle movable part is pressed, the air pressure in the low-temperature cabinet and the air pressure outside the low-temperature cabinet can be balanced so that the door can be quickly opened.

Description

technical field [0001] The invention relates to a low-temperature cabinet part, in particular to a door handle and a door of a low-temperature cabinet air pressure automatic balance. Background technique [0002] After the low-temperature cabinet is refrigerated, the temperature inside the cabinet drops, and the air pressure drops, which increases the pressure difference inside and outside the cabinet, making it difficult to open the door of the low-temperature cabinet. Therefore, there is an urgent need for a kind of air pressure inside and outside the box that can be quickly balanced, light [0003] Loosen the door handle of the freezer. Relevant low-temperature cabinet air pressure automatic balance door handle and door of the present invention have no report at present. Contents of the invention [0004] In order to solve the above technical problems, the present invention relates to a low-temperature cabinet air pressure automatic balance door handle and door. open...
