Description
Technical field
The utility model relates to a kind of connector, in particular to it is a kind of air pressure, liquid is closely knit test used in connector.
Background technique
Industrial barrel cage must all have certain leakproofness and resistance to pressure, so requiring to be sealed before factory
Property and pressure detecting.All it is one connector of installation on barrel cage at present, is then connect by hose with detector, to carry out
Detection, this connector are associated keys between air pressure, the close machine of liquid and laboratory sample.But current connection header structure
Complexity, erroneous for installation, itself poor sealing between barrel cage, so the result of detection is also inaccurate.
Utility model content
The purpose of the utility model is to provide a kind of structure is simple, easy to operate connector.
Realizing the technical solution of the utility model aim is:
A kind of connector, including the screw rod with air flue, and the shell, elastomer block and the limited block that are sheathed on screw rod,
The elastomer block and limited block are set in turn in the lower section of shell, and the bottom of elastomer block is held at the top of limited block, elasticity
Gap is formed between the top of block and the bottom of shell；Intermeshing turbine and worm screw, Cover For A Turbine are equipped in the shell
On screw rod, and turbine is to be threadedly coupled with screw rod, and top and the shell of turbine fit, and the both ends of worm screw are set to shell
On, the axial direction of the turbine and the axial direction of worm screw are mutually perpendicular to.
Further, it is connected between the both ends of the worm screw and shell by bearing.
Further, the outside of the shell is equipped with the handle being connected with worm screw one end.
Further, the bottom of the shell is equipped with rubber sealant.
Further, the screw rod includes top, varying diameter portion and lower part, and the diameter on top is greater than the diameter of lower part, variable diameter
Portion is in the junction of screw rod and shell.
Further, the shell and elastomer block and screw rod are slidable connection.
Further, the limited block is to be threadedly coupled with screw rod.
Using above-mentioned technical proposal, the utility model has below the utility model has the advantages that (1) the utility model will be on screw rod
Elastomer block insertion barrel cage hole in, shell rides on the surface of barrel cage, and then rotary worm makes turbine rotation, due to turbine
It is to be threadedly coupled, and the top of turbine fits with shell, so screw rod just moves upwards, resists at the top of elastomer block with screw rod
Shell, gap disappears at this time, and elastomer block is in hole, and the bottom of elastomer block has limited block to be limited, therefore with spiral shell
Bar constantly moves upwards, and elastomer block is just constantly extruded, so that the axial shrinkage of elastomer block, and be radially expanded, thus firm
It being stuck in the hole of barrel cage firmly, structure is simple, and it is easy to operate, and can guarantee the leakproofness between the present apparatus and barrel cage, have
Conducive to the accuracy for improving test.
(2) it is connected between the both ends of the worm screw of the utility model and shell by bearing, sound construction, and turn convenient for worm screw
It is dynamic.
(3) the utility model uses handle, thus effectively rotary worm.
(4) shell can be fixed on screw rod by the varying diameter portion of screw rod and worm screw by the utility model, and pass through change
Diameter portion can make have opposite displacement slightly between screw rod and shell.
Detailed description of the invention
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, wherein
Fig. 1 is the structural schematic diagram of the utility model.
In attached drawing, air flue 1, screw rod 2, top 21, varying diameter portion 22, lower part 23, shell 3, elastomer block 4, conical socket 41, limit
Position block 5, turbine 6, worm screw 7.
Specific embodiment
(embodiment 1)
