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 permanent joint device, specifically, relate to a kind of fixing device that is used for large-scale liquid transfer adapter glass.
Background technique
Usually adopt elastic cord fixing glass joint in the large volume liquid asepsis transmission course, though adopt the elastic cord low price, easy to use, in high-pressure process, very easily make its loss of elasticity, toughness reduces; Run into fluid pressure when excessive, can cause the liquid splash, seriously influence the delivery safety of liquid; And when changing joint, hand touches the jointing of joint easily, and potential pollution hidden trouble is arranged.
Therefore, need that research and design is a kind of can effectively avoid leak of liquid between the adapter glass, easy to operate and safe adapter glass fixing device.
Summary of the invention
The objective of the invention is to address the above problem, a kind of fixing device that can avoid leak of liquid between the adapter glass effectively is provided.
In order to realize the object of the invention, adapter glass fixing device of the present invention comprises two fixation clamps, fixing rod, spring, movement rod and two trigger sheets that are used for fixing the adapter glass projection, and described movement rod is the z font, and is sheathed on the described fixing rod; Wherein a fixation clamps is located at an end of described fixing rod, described fixation clamps bottom links to each other with a trigger sheet by described spring, described trigger sheet is sheathed on the described fixing rod and with described movement rod one end and links to each other, another fixation clamps is fixed at the other end of described movement rod, and another trigger sheet is fixed at the other end of described fixing rod.
Wherein, described fixing rod is provided with the projection that is used for spacing trigger sheet and movement rod, is positioned near the middle part of described fixing rod.
Described fixation clamps links to each other with described spring.In use, when clutch two trigger sheets with hand, described spring just opens, and can drive the fixation clamps that is fixed in fixing rod one end and open, can be by taking off or install the adapter glass fixing device on the adapter glass.
Described two fixation clamps, described two trigger sheets lay respectively at the upper and lower of described fixing rod.
Described movement rod is provided with sleeve pipe outward, sleeve pipe be shaped as tubular, the top is provided with chute, guarantees that sleeve pipe, movement rod move horizontally along fixing rod, and cooperates with projection, with the limit slippage scope.
Described trigger sheet and described spring and described movement rod link together.
Adapter glass fixing device of the present invention, can avoid leak of liquid between the adapter glass effectively, four projectioies of adapter glass can be fixed, make the attachment portion of adapter glass tightr, make it be unlikely to slippage, and this fixing device is high temperature resistant, is easy to carry out sterilization treatment because fluid pressure is excessive, hand does not reach the jointing of adapter glass in the operating process, and the Security of operating is improved greatly.Therefore when carrying out liquid transfer in enormous quantities with adapter glass, the use of adapter glass fixing device can improve the Security of production greatly, simultaneously, the adapter glass fixing device also have volume little, be convenient to characteristics such as dismounting, can be used for cell jar etc. and need carry out the large volume liquid transfer, be suitable in fermenting tub laboratory and production process, using.

Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Fig. 1 is the structural representation sketch of adapter glass fixing device of the present invention; As shown in Figure 1, adapter glass is made up of fixing rod 11, trigger sheet 20a, 20b, fixation clamps 30a, 30b, spring 40, movement rod 13, projection 12 with fixing device.
The longitudinal section of fixing rod 11 is square, and fixing rod 11 is provided with the projection 12 that is used for spacing trigger sheet 20a and movement rod 13, is positioned near the middle part of described fixing rod 11, guarantees that trigger sheet 20a can only slide at protruding 12 left ends, is unlikely to slippage from the fixing rod 11.
As shown in Figure 2, the outer sleeve pipes 10 that also are provided with of movement rod 13, sleeve pipe 10 be shaped as tubular, the top is provided with chute 30c, guarantees that sleeve pipe 10, movement rod 13 move horizontally along fixing rod 11, and cooperates with projection 12, with the limit slippage scope.
Each parts of adapter glass fixing device 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 hand, trigger sheet 20a slides to the left, drive spring 40 expansions, movement rod 13 also slides to the left, makes fixation clamps 30a, 30b relative distance widen, even fixation clamps 30a, 30b open from adapter glass 1, finally can take off or install this adapter glass fixing device.
Though 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.
