Description
Technical Field
The utility model belongs to the field of machinery, a coupling is related to, in particular to capillary joint.
Background
The joint is a device which is arranged between the pipe fittings and has certain sealing performance so that two or more pipe fittings can continuously run. At present, the capillary tube joint on the market can only be generally connected with a tube fitting with one specification, and in order to connect capillary tubes with different specifications, various manufacturers generally need to produce products with various sizes, so that the production cost of the manufacturers is increased, the enterprise benefit is reduced, inconvenience is brought to consumers, and the use cost is increased.
The capillary that multiple specification can be realized to a certain extent to current capillary joint that has a plurality of sockets connects, application number "CN202122549615.8", the patent name "swift formula capillary coupling" the published patent document of inlaying, it provides an inlay type capillary and connects, including the housing nut, housing nut one side threaded connection has the adapter, the fixed through-hole that is provided with in one side that the adapter was kept away from to the housing nut, housing nut is inside and be close to the through-hole department slip and be provided with the coupling, the inside fixed metal tubule that is provided with of coupling, the fixed connecting hole that is provided with of one end that the adapter is close to the external screw thread, it can realize the use of different specification capillaries through changing above-mentioned coupling. But the mode of fixing the sealed capillary by extrusion has higher dimensional matching requirements on the pipe joint and the connecting hole, and the whole joint still needs to be replaced when the capillary with slightly larger diameter difference is selected. And the capillary is easy to deform or damage after being extruded by the connecting hole, so that a flow channel is influenced, the fluid medium is blocked or even blocked, and the actual use is influenced.
Therefore, a capillary tube joint which is suitable for connecting capillary tubes with various specifications, is convenient to mount and dismount and is reliable in use is needed at present.
Disclosure of Invention
The utility model aims at the above-mentioned problem that exists among the prior art, provide a cutting ferrule formula capillary coupling convenient to detach, the structure is reliable.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a cutting ferrule formula capillary coupling which characterized in that, is including connecting main part and coupling, joint main part left side seted up the mounting hole that a plurality of supplied coupling to connect the usefulness, the coupling be used for connecting the capillary and connect in corresponding mounting hole, joint main part right side external fixation have a coupling nut, joint main part right side internal fixation have the adapter.
In the ferrule type capillary tube joint, the tube joint and the joint main body are sealed by the O-shaped ring I, the outer side of the tube joint is sleeved with the clamping ring, the clamping ring is sleeved with the locking cap, and the locking cap is in threaded connection with the joint main body.
In foretell ferrule type capillary coupling, the joint main part constitute by coupling section, changeover portion and adapter section, coupling section outline be the triangle-shaped form, the changeover portion outline be the toper form, adapter section outline be cylindrical shape.
In foretell ferrule type capillary coupling, joint main part and coupling nut pass through the steel ring chucking, the adapter inner be fixed in the joint main part to it is sealed through O shape circle two, the outer end of adapter is used for connecting the external joint of treating the switching.
Compared with the prior art, the ferrule type capillary joint can realize the installation of capillaries with different specifications under the condition of only replacing the pipe joint through the detachable pipe joint, and has the advantages of being convenient for manufacturers to produce and stock, saving cost and being beneficial to the quick operation of users.
