Abstract

The utility model provides a novel lateral opening and closing door mechanism and the structure solves the technical problems that a large area is needed in opening or closing a door and the structure can not be connected with other equipments on a production line to form an assembly-line operation. The utility model comprises a door frame (1), a door body (3) and a cylinder flange (4), and is characterized in that slide rails (7) are respectively arranged on an upper frame and a lower frame of the door frame (1), a door support (8) is fixedly arranged on the door body (3) of which the side (3) is fixedly connected with a support plate (6), a pulley is arranged on the lower portion of the support plate (6), and the pulley slides from left to right on the slide rail (7) achieving fast lateral opening and closing of a vessel door body. The utility model has the beneficial effects that the production needs of the production line of a large Liquid Crystal Display device in a clean workshop are capable of being satisfied, the structure is simple, no dust is produced by the friction, and the bubbles which are produced when two materials with large size are adhered on a adhesion place are eliminated.

Description

A quick side door opening mechanism for positive and negative pressure containers

technical field

The utility model relates to a door opening mechanism of a large pressure vessel, in particular to a side switch mechanism of a pressure vessel used for eliminating air bubbles generated between a polarizer and a glass box of an LCD production line.

Background technique

At present, the door opening and closing method of large pressure vessels at home and abroad mainly adopts the ring gear meshing method to realize sealing. When opening and closing the door, the hinge welded on the cavity is used as the axis to rotate the door. On the LCD production line, if the equipment adopts the conventional revolving door opening method, it is difficult to connect with the equipment in the front and rear processes to form an assembly line, which will affect the work efficiency and occupy a large space.

Contents of the invention

The utility model provides a new side door opening and closing mechanism, which solves the technical problem that it needs to occupy a large area when opening and closing the door, and cannot be connected with other equipment on the production line to form an assembly line operation. Pressure vessels are used in clean spaces.

The technical scheme that the utility model solves its technical problem adopts is:

The quick side door opening mechanism for positive and negative pressure containers includes a door frame 1, a door body 3, and a cylinder flange 4. Slide rails 7 are respectively arranged on the upper and lower frames of the door frame 1, and the door body 3 is fixed A door support 8 is provided, and its side is fixedly connected with a support plate 6, and a pulley 9 is arranged under the support plate 6, and the pulley 9 slides left and right on the slide rail 7 to realize the fast lateral opening and closing of the container door.

The left half circle of the cylinder flange 4 can also be provided with a semicircular cylinder gear ring 5 , and the right half circle of the door body 3 can be provided with a semicircular door gear gear 2 .

The beneficial effect of the utility model is that it can meet the production needs of large-scale LCD display devices in clean workshops, has a simple structure, does not generate dust due to friction, and can meet the requirements of eliminating air bubbles generated at the adhesion when two large-sized materials are adhered.

Detailed ways

The side switch door structure includes a door frame 1, a semicircular door ring gear 2, a door 3, a cylinder flange 4, a semicircle cylinder gear ring 5, a support plate 6, a slide rail 7, a door support 8 and a pulley 9. When the door is closed, the pulley drives the door to run in the direction of the slide rail. The left part of the door 3 is inserted into the semicircular cylinder gear ring 5, and the right side of the cylinder flange 4 is inserted into the semicircular cylinder gear gear 2, and then compressed air is used to The sealing ring in the sealing groove on the cylinder flange is pushed out and pressed against the large ring gear to realize sealing. The trajectory of the door 3 is determined by the slide rail 7 installed on the door frame 1, the door 3 is fixed by the door support 8, and can easily slide in the slide rail 7 by the pulley 9 installed on the support plate 6 connected thereon.
