Abstract
The invention provides a fixing device for a glass joint. The fixing device comprises two fixing clamps (30a, 30b) for fixing a protrusion of the glass joint, a fixing rod (11), a spring (40), a moving rod (13) and two trigger plates (20a, 20b), wherein the moving rod (13) is z-shaped and sleeved on the fixing rod (11); and the fixing clamp (30a) is arranged at one end of the fixing rod (11), the bottom of the fixing clamp (30a) is connected with the trigger plate (20a) through the spring (40), the trigger plate (20a) is sleeved on the fixing rod (11) and connected with one end of the moving rod (13), the fixing clamp (30b) is fixedly arranged at the other end of the moving rod (13), and the trigger plate (20b) is fixedly arranged at the other end of the fixing rod (11). The fixing device has small volume, is easy for sterile treatment, is not in contact with the connecting part of the joint in use, and is suitable to be used in laboratory and production processes of a fermentation tank.
Description
Technical field
The present invention relates to a kind of anchor tip device, specifically, relate to a kind of fixture for large-scale liquid transfer glass connector.
Background technology
Usually adopt rubber band fixing glass joint in the large volume liquid asepsis transmission course, although adopt the rubber band low price, easy to use, in high-pressure process, very easily make its loss of elasticity, toughness drop; Run into fluid pressure when excessive, can cause the liquid splash, seriously affect the delivery safety of liquid; And when changing joint, hand touches the seam of joint easily, and potential pollution hidden trouble is arranged.
Therefore, need that research design is a kind of can effectively avoid leak of liquid between the glass connector, easy to operate and safe fixing device for glass joint.
Summary of the invention
The object of the invention is to address the above problem, a kind of fixture that can effectively avoid leak of liquid between the glass connector is provided.
In order to realize the object of the invention, fixing device for glass joint of the present invention comprises two fixation clamps, fixed bar, spring, carriage release lever and two trigger sheets that are used for fixing glass joint projection, and described carriage release lever is the z font, and is sheathed on the described fixed bar; Wherein a fixation clamps is located at an end of described fixed bar, described fixation clamps bottom links to each other with a trigger sheet by described spring, described trigger sheet is sheathed on the described fixed bar and with described carriage release lever one end and links to each other, another fixation clamps is fixed at the other end of described carriage release lever, and another trigger sheet is fixed at the other end of described fixed bar.
Wherein, described fixed bar is provided with the projection for spacing trigger sheet and carriage release lever, is positioned at the near middle of described fixed bar.
Described fixation clamps links to each other with described spring.In use, when clutch two trigger sheets with hands, described spring just opens, and can drive the fixation clamps that is fixed in fixed bar one end and open, can be by taking off on the glass connector or mounting glass joint fixture.
Described two fixation clamps, described two trigger sheets lay respectively at the upper and lower of described fixed bar.
Described carriage release lever is provided with sleeve pipe outward, sleeve pipe be shaped as tubular, the top is provided with chute, guarantees that sleeve pipe, carriage release lever move horizontally along fixed bar, and cooperates with projection, with the limit slippage scope.
Described trigger sheet and described spring and described carriage release lever link together.
Glass connector fixture of the present invention, can effectively avoid leak of liquid between the glass connector, four projections of glass connector can be fixed, make the coupling part of glass connector tightr, make it be unlikely to the slippage because fluid pressure is excessive, and this fixture is high temperature resistant, is easy to carry out sterilization treatment, hand does not reach the seam of glass connector in the operating process, and the safety that operates is improved greatly.Therefore when carrying out liquid transfer in enormous quantities with glass connector, the use of glass connector fixture can improve the safety of production greatly, simultaneously, the glass connector fixture also have volume little, be convenient to the characteristics such as dismounting, can be used for cell tank etc. and need to carry out the large volume liquid transfer, be suitable in fermentation tank laboratory and production process, using.

1 glass connector
The specific embodiment
Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Fig. 1 is the structural representation sketch of glass connector fixture of the present invention; As shown in Figure 1, fixing device for glass joint is comprised of fixed bar 11, trigger sheet 20a, 20b, fixation clamps 30a, 30b, spring 40, carriage release lever 13, projection 12.
The vertical section of fixed bar 11 is square, and fixed bar 11 is provided with the projection 12 for spacing trigger sheet 20a and carriage release lever 13, is positioned at the near middle of described fixed bar 11, guarantees that trigger sheet 20a can only slide at protruding 12 left ends, is unlikely to slippage from the fixed bar 11.
As shown in Figure 2, the outer sleeve pipes 10 that also are provided with of carriage release lever 13, sleeve pipe 10 be shaped as tubular, the top is provided with chute 30c, guarantees that sleeve pipe 10, carriage release lever 13 move horizontally along fixed bar 11, and cooperates with projection 12, with the limit slippage scope.
Each parts of glass connector fixture of the present invention can adopt metal material to make, and are high temperature resistant, are easy to carry out sterilization treatment.
As Figure 1-3, in use, when pulling trigger sheet 20a and 20b with hands, trigger sheet 20a slides to the left, drive spring 40 expansions, carriage release lever 13 also slides to the left, so that fixation clamps 30a, 30b relative distance widen, even fixation clamps 30a, 30b open from glass connector 1, finally can take off or install this glass connector fixture.
Although above the present invention is described in detail with a general description of the specific embodiments, on basis of the present invention, can make some modifications or improvements it, this will be apparent to those skilled in the art.Therefore, these modifications or improvements all belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
