Sebific duct will not knot, wind or spiral, so as to solve the problems, such as that female Luer is easily unclamped, come off；Retainer ring, which is blocked, to be connect
Head fixed cover, preventing joint fixed cover, solving joint fixed cover and easily being skidded off from adapter body causes joint from sliding axially
The problem of core comes off with adapter body.
Neck is offered on the segment inwall of the adapter body endoporus, is provided with and blocks on the step surface of adapter body endoporus
The slot to make way of groove connection, the annular boss set in the joint core are caught in neck, and both are engaged by clamping.Above structure is stepped down
Groove provides avoiding space, the annular boss in joint core is laterally caught in neck, and be caught in rear joint core can be relative to
Adapter body rotates freely, but can not depart from adapter body vertically, ensures that the liquid conducting pipes of flusher lead to
Cross the reliability that the utility model is connected with Gastrointestinal Endoscopes diagnostic equipment jaw.
In order to simplify structure, facilitate processing and fabricating and assembling, and be advantageous to be connected with female Luer, the joint core front end
Head be path section, the path section is stretched into the segment of adapter body endoporus, and annular boss is formed with path section,
The rear end of joint core is provided with external screw thread.
Assembled for the ease of resigning groove processing and joint fixed cover, it is axially disposed in the big section of the adapter body endoporus
There is vertical slot, the vertical slot connects composition " L " shape structure with slot to make way.
The retainer ring (4) is sleeved in joint core, is held out against by the sunk screw radially worn, such fixed cover is in joint
The fixing connected on core is good, and disassembling operations are very convenient.
Preferably, the joint fixed cover is made up of PP materials, joint core, adapter body and retainer ring are by stainless steel
Into.
Beneficial effect：The utility model joint core can rotate freely relative to adapter body, efficiently solve Rule and connect
The problem of head easily unclamps, come off；Retainer ring blocks joint fixed cover, joint fixed cover is solved joint from sliding axially
Fixed cover is easily skidded off from adapter body the problem of causing joint core to be come off with adapter body.The utility model is ingenious in design, knot
Structure is simple, and assembling is convenient, and transformation is easy, and improvement cost is low, is applicable on the various diagnostic equipments for avoiding pipeline from rotating.
