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
?
Technical field
The present invention relates to the technology that is tightly connected of glass tube, more particularly, relate to a kind of vacuum seal folder.
Background technique
Be used for the vacuum gas filling equipment that light fixture is produced, formation that mostly its vacuum line and loading line are that glass tube links to each other with glass tube or glass tube links to each other with metal tube.At present, between glass tube and the glass tube through sintering, but when glass tube stressed then very easily broken, but and be to be connected between glass tube and the metal tube through valve, have the problem of leaking gas easily, cause the connectivity problem of glass tube can't solve preferably always.
Summary of the invention
To the above-mentioned shortcoming that exists in the existing technology, the purpose of this invention is to provide a kind of vacuum seal folder, it is broken that the sealing folder can avoid glass tube to take place, and guarantees being tightly connected between pipe.
For realizing above-mentioned purpose, the present invention adopts following technological scheme:
This vacuum seal folder comprises flange snap ring, Sealing and fastening piece, and two flange snap rings are symmetrical set, and an end pin-connect, and Sealing is located at the inner ring of flange snap ring, and fastening piece is located at the other end of two flange snap rings, and the two flange snap ring the other ends are tightened each other.
Be provided with a connecting piece between described two flange snap rings, one end, the connecting sheet two ends are respectively equipped with pin-and-hole, and this end of two flange snap rings also respectively is provided with a bearing pin, and passes corresponding pin-and-hole respectively and pin joint through bearing pin.
The other end of described two flange snap rings has a binding groove, and described fastening piece comprises screw rod and wing nut, and screw rod one end passes binding groove and is connected fixing with wing nut.
The inner ring both sides of described flange snap ring are respectively equipped with the inclined-plane, and described Sealing is an O-ring seals, and two O-ring seals are located in the inclined-plane respectively.
In technique scheme; Vacuum seal folder of the present invention comprises flange snap ring, Sealing and fastening piece; Two flange snap rings are symmetrical set, and an end pin-connect, and Sealing is located at the inner ring of flange snap ring; Fastening piece is located at the other end of two flange snap rings, and the two flange snap ring the other ends are tightened each other.Adopt the sealing folder can two glass tubes or glass tube be fixedly clamped with metal tube mutually, and it is broken to avoid glass tube to take place, and has also guaranteed sealing.Advantages such as in addition, the sealing folder also has installation, convenient disassembly, quick, and versatility is good.
Description of drawings
Fig. 1 is the three-dimensional structure diagram of vacuum seal folder of the present invention;
Fig. 2 is the STRUCTURE DECOMPOSITION figure of vacuum seal folder of the present invention.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and embodiment.
See also Fig. 1, shown in Figure 2; Vacuum seal of the present invention folder 10 comprises two semicircular flange snap rings 11, Sealing 12 and fastening piece 13, and wherein, two flange snap rings 11 are symmetrical set and constitute similar buckle-like; An and end pin-connect of two flange snap rings 11; Sealing 12 is located at the inner ring of flange snap ring 11, and fastening piece 13 is located at the other end of two flange snap rings 11, and two flange snap rings, 11 the other ends are tightened each other.Concrete structure is following: be provided with a connecting piece 14 between two flange snap rings, 11 1 ends; Connecting sheet 14 two ends are respectively equipped with pin-and-hole 141; This end of two flange snap rings 11 also respectively is provided with a bearing pin; And pass corresponding pin-and-hole 141 respectively through bearing pin 142, and make the mutual pin joint of this end of two flange snap rings 11, can realize the opening and closing action of clips 10.And the other end of two flange snap rings 11 has a binding groove 111; 13 of above-mentioned fastening pieces comprise screw rod 131 and wing nut 132; Screw rod 131 1 ends pass binding groove 111 and are connected fixing with wing nut 132; Thereby can be through manual rotation wing nut 132, the flange snap ring 11 on both sides is shunk relatively and clamp.And the inner ring both sides of flange snap ring 11 are respectively equipped with the inclined-plane, and above-mentioned Sealing 12 is an O-ring seals, and two O-ring seals are located at respectively in the inclined-plane, and the internal diameter size of O-ring seals is suitable with the pipe fitting external diameter that needs to be connected.
During use; Can earlier two Sealings 12 be enclosed within respectively on the flange of two pipe fittings connecting end; Then flange snap ring 11 is enclosed within on the two pipe fittings connecting end, and two seal rings are in respectively in the inclined-plane of flange snap ring 11, pass binding groove 111 through screw rod 131 then; And tighten through wing nut 132, make the inclined-plane of flange snap ring 11 be adjacent to mutually with the flange of pipe fitting connecting end.Because flange snap ring 11 is when tightening up fixedly; Its active force acts directly on the O-ring seals, can't impact glass tube, has avoided the fragmentation of glass tube; And employing sealing folder 10 makes that the connection replacing is convenient between pipe; Can lock fast and open, not only can be applied in the vacuum gas filling equipment, but also can be widely applied to the occasion that is tightly connected between other tube and tube.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention; As long as in connotation scope of the present invention, all will drop in claims scope of the present invention the above embodiment's variation, modification.
