Description

Automatic switch sealing door device

Technical Field

The invention belongs to the technical field of sealing doors, and particularly relates to an automatic opening and closing sealing door device.

Background

Sealing, a measure to prevent leakage of the working medium from the machine (or equipment) or intrusion of foreign substances into the interior thereof. The working medium to be sealed may be a gas, a liquid or a powdery solid. Poor sealing can reduce machine efficiency, create waste and pollute the environment. Leakage of working media of flammable, explosive or toxic nature can compromise personnel and equipment safety. The invasion of gas, water or dust into the equipment can pollute the working medium, affect the product quality, increase the abrasion of parts and shorten the service life of the machine. The sealing is divided into static sealing and dynamic sealing. The seal between the relatively stationary parts of the machine (or in the plant) is called a static seal; the seal between the relatively moving parts is called a dynamic seal.

In the field of mechanical structure sealing doors, most sealing doors are manually operated or can be operated by a plurality of executing components; the use is extremely inconvenient, and therefore, the inventor provides an automatic opening and closing sealing door device by combining various factors.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-3, an automatic switch sealing door device includes sealed cabin 10, be provided with hinge seat board 9 on the sealed cabin 10, it has the apron to articulate on the hinge seat board 9, be provided with upper cover connecting plate 8 on the apron, upper cover connecting plate 8 outer end is provided with locking hook plate 7, and locking hook plate 7 tip articulates there is

3, and 3 outer ends of push rod are installed on upper cover connecting plate 8 through inner ring wheel and

outer pulley

6, 3 middle parts of push rod are provided with link 2, and 2 outer ends of link are connected with driving cylinder 1.

Wherein, the cover plate is hinged with the hinged support plate 9 through a hinged shaft 11.

Wherein, a pulley limiting block 4 is arranged on the push rod 3 corresponding to the inner pulley 5.

An oil cylinder seat 12 is arranged at the outer end of the upper cover connecting plate 8 corresponding to the driving oil cylinder 1, and the driving oil cylinder 1 is installed on the oil cylinder seat 12.
