New description: ^[New technical field] ^ This creation provides a leak-proof structure for vacuum coating machine (1), especially for the technically providing a leak-proof and three-dimensional type. a ring, and the ring is a hollow inflatable. [Prior Art] In general, the assembly of the mechanism is inevitably caused by the relationship between the material of the member and the processing accuracy, but the gap may cause leakage, etc., sometimes it is not allowed, such as in the delivery of gas or liquid. In the pipeline, the gap will allow gas or liquid to leak out. For the vacuum coating machine, the leak-proof structure will not leak when the vacuum coating machine is applied between the separate joint members. Goal, however, the familiar structure obviously does not achieve this goal. The conventional shackle type ring is mainly arranged between the mechanism and the mechanism, and is made solid and has a certain elasticity, so as to provide the deformation of the conventional 〇#-type ring and to achieve the purpose of sealing when the mechanism is locked. It is difficult to recover after the deformation of the conventional ring. However, the above-mentioned conventional 〇-type ring still has the following defects: 1 · Because the conventional 〇-type ring system is made of solid and has some elasticity to provide the deformation sealing effect when the compression seal is used, but because the solid 〇-shaped ring is long In the state of pressure deformation, it will be shaped and cannot be recovered. If it is used on a mechanism that often needs to be separated and combined, the deformed 〇-shaped ring will not be effectively sealed and easily: 3⁄4 leaking. 2 · The conventional () type ring is generally made into a solid ring-shaped () type ring. The use of the real M289774, heart-shaped () type ring is limited by the leak-proof technology that can only compress and deform.升, 〇 效 , 而成 而成 而成 而成 而成 而成 而成 而成 而成 而成 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发 开发To the extent that the operation of the processing process, Jin Jinde: into the partition to create a close, can form a space of the chamber, but it still has the following defects: 1 · the degree of precision machining to close, the processing accuracy must refer to The cost of the cost is also more, but still can not achieve the actual leakage prevention effect. 2 · How can the metal material be accurately processed without the exact processing? #果, the use of metal materials as a close material, the innate existence of the loss lies in the mechanical multiple points After the combination, it will also affect the effect of the fit and the incompleteness of the fit. Therefore, in view of the problems existing in the above-mentioned conventional structure, how to create an innovative structure with more ideals and practicability, and the eagerness of consumers and the relevant industry must strive to develop the goal and direction of breakthrough.

The anti-state used on the machine is precision-processed with sheet metal, which is not good for leak prevention and increases the expenditure. Technical characteristics of solving the problem: providing a leak-proof junction of a vacuum coating machine M289774 - structure (a) ... the leak-proof structure () type ring before the '彳t and has an inflatable ancestor-type ring inside the hollow, this The group of the 〇-shaped ring is arranged in the vacuum coating, the structure, and is inflated to make the 〇-shaped ring expand and deform to fill the gap between the mechanisms, so as to achieve the purpose of leakage prevention and sealing, and can be separated after being deflated. Three-dimensional type 〇-type ring, expansion seal and leak-proof and facilitate the leakage prevention between the mechanisms of separation and combination. Compared with the effect of the prior art: to provide a vacuum coating machine (I), which is different from the conventional ring-shaped solid ring, and the original structure of the structure is hollow and inflatable for expansion, and The seals used for compression and deformation are not the same. The 〇-shaped ring of this creation can be used as a leak-proof mechanism for separation and combination, while the conventional 〇-type ring is not conducive to the use of the state. .
