Embodiment Construction

[0027] In the following, the technical means adopted by the present invention to achieve the intended purpose of the invention will be further described in conjunction with the accompanying drawings and preferred embodiments of the present invention.

[0028] see figure 1 and figure 2 As shown, the sealing assembly of the present invention includes a housing 10 and a gate 40 that is mutually pivoted, and it is provided with at least one power device (not shown in the figure), and the power device is provided with a movable part that can be driven. The part can move relative to the casing 10, and a connecting rod group 30 corresponding to the power device is provided, which is installed on the casing 10 and the power device and can be driven by the moving part. The gate 40 is pivotally arranged on the connecting rod group 30 and is driven to rotate by the connecting rod set 30 .

[0029] One of the specific embodiments of the present invention can be designed to include a ca...

Abstract

The invention provides a seal assembly which comprises a shell body and a gate which is connected with the shell body in a pivot mode, a toggle connecting rod set which is driven by power devices is connected with the gate in a pivot mode, closes the gate in a rotating mode and is capable of effectively abutting against and sealing an opening. A toggle mechanism is simple in structure, can provide high output by low power and can reduce output of the power devices. Due to the fact that the connecting rod set is arranged between the power devices and the gate, time difference of all power devices can be absorbed. The seal assembly can complete a seal motion through a single motion, is simple in structure, and meanwhile solves the problems that the existing seal assembly can not simplify a mechanism to reduce cost, output of pneumatic cylinders and time difference caused by a plurality of the pneumatic cylinder can not be reduced.

Description

technical field [0001] The invention relates to a sealing device, especially a sealing assembly. Background technique [0002] In many sophisticated high-tech industries, such as semiconductor factories such as wafers, a high degree of sealing is required to prevent dust particles from entering equipment or products. At this time, sealing components are used for wafer transfer gates and the like. There are two main types of sealing components: [0003] One includes a pneumatic cylinder and a gate. The pneumatic cylinder pushes the gate obliquely up and down to seal the transverse opening; however, since the pneumatic cylinder can only move the gate up and down, the gate lacks lateral fixing force to tightly abut against the transverse opening. Therefore, the gate requires a special shape and design to achieve a high degree of airtightness, but the production cost of the gate is increased due to the high difficulty of gate fabrication. [0004] Second, it includes two-direc...
