Abstract

The invention discloses a vacuum sealing clip, which comprises two flange snap rings, sealing pieces and fastening pieces, wherein the two flange snap rings are symmetrically arranged, one ends of the flange snap rings are in pin joint, the sealing pieces are arranged at the inner rings of the flange snap rings, the fastening pieces are arranged at the other ends of the two flange snap rings, and the other ends of the two flange snap rings are mutually clamped. Two glass pipes or a glass pipe and a metal pipe can be clamped to be fixed by the sealing clip, the glass pipes can be prevented from being broken, and the sealing performance is also ensured. In addition, the sealing clip is convenient and quick to assemble and disassemble, and has the advantages of good generality and the like.

Description

[0001] technical field [0002] The invention relates to the sealing connection technology of glass tubes, more specifically, to a vacuum sealing clip. [0003] Background technique [0004] In the vacuum inflatable equipment used in the production of lamps, the vacuum pipeline and inflatable pipeline are mostly composed of glass tubes connected with glass tubes or glass tubes connected with metal tubes. At present, the glass tube is sintered with the glass tube, but when the glass tube is stressed, it is very easy to break, and the glass tube and the metal tube are connected by a valve, which has the problem of easy air leakage, resulting in the failure of the glass tube. The connection problem has not been solved well. [0005] Contents of the invention [0006] In view of the above-mentioned shortcomings in the prior art, the purpose of the present invention is to provide a vacuum sealing clip, which can prevent glass tubes from breaking and ensure the sealed connect...
