Technical field
The utility model relates to a kind of hose couplings more particularly to a kind of high-intensitive snap ring-type to lock waterproof hose connector.
Background technique
Hose coupling is roughly divided into metal mold, shaped plastics, three kinds of metallo-plastic mixed type by material point.Divide by functionality,
It is broadly divided into quick hose joint, right angle hose coupling, locking hose coupling, snap ring-type hose coupling, locking card
Ring type hose coupling etc..
Hose coupling is similar compared with the functionality of cable connector, needs to achieve the effect that sealing is fixed, hose coupling
Structure consists essentially of three parts, is made of adapter body, fixed mechanism, sealing mechanism, and adapter body, which is mounted in, penetrates hole
Position, be usually threadedly coupled based on；Fixed mechanism usually prevents hose from axially and radially generating relative movement, and
There is certain fixed anti-pulling ability；Sealing mechanism is to make hose and penetrate to reach between hole to be fully sealed, the work of such equipment
Space can be isolated with external environment, reach the protective actions such as water proof and dust proof.
Existing conventional hoses connector, since sealing mechanism and hose cooperation are insufficient, generally existing sealing effect is paid no attention to
Phenomena such as the phenomenon that thinking, leak gas leakage, dust enter frequent occurrence, so that occurring security risk inside equipment.In addition, some are general
The fixed mechanism of logical hose coupling is not perfect, solid failure or fixed incomplete phenomenon often occurs, so that hose
It can produce biggish displacement, the accessory inside equipment damaged.
However, existing metal locks hose coupling now, and expensive and installation operability is bad etc., so that needing to pay
High cost goes to realize the effect of lock sealing out, some would not select this hose coupling due to cost considerations.Cause
