Detailed Description

It should be noted that, without conflict, the embodiments and features of the embodiments in the present application may be combined with each other, and the present utility model will be further described in detail with reference to the drawings and the specific embodiments.

In the embodiment of the present utility model, if there is a directional indication (such as up, down, left, right, front, and rear … …) only for explaining the relative positional relationship, movement condition, etc. between the components in a specific posture (as shown in the drawings), if the specific posture is changed, the directional indication is correspondingly changed.

In addition, descriptions of "first," "second," and the like in embodiments of the present utility model are for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying an order of magnitude of the indicated features. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 7, an automatic door opening device for a cabinet includes: the cabinet comprises a rectangular frame at the front end of the cabinet, an upper electromagnet block, a lower electromagnet block, a hydraulic push rod, a door post micro-switch, a cabinet door, a cabinet lock hook arranged on the cabinet door and a shaft for connecting the rectangular frame and the cabinet door, wherein the upper electromagnet block is arranged on the upper portion of the rectangular frame, the lower electromagnet block is arranged on the lower portion of the rectangular frame, the door post micro-switch is arranged on one side, opposite to the shaft, of the rectangular frame, the cabinet lock hook and the door post micro-switch are correspondingly arranged, the hydraulic push rod is perpendicular to the rectangular frame and is opposite to the cabinet door, and the hydraulic push rod is provided with a thrust in a door opening direction to the cabinet door for a long time.
