The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure 1, a kind of light rotary hose interface comprises core pipe 01 and rotary hose 04, and core pipe 01 is the metal tube that is linked to each other and consisted of by connector 011 and joint pin 012 one.As shown in Figure 2, joint pin at core pipe 01 is processed with pawl, pawl is to be made of anticreep plane 013, connection cylinder 014 and the guiding conical surface 015, anticreep plane 013 is positioned on the cross section of core pipe 01, it is parallel with the axis of core pipe 01 to connect cylinder 014, and the guiding conical surface 015 tilts towards the end of joint pin 012 away from connector 011.At the flexible sealing shroud 03 of joint pin 012 cover of core pipe 01, joint pin 012 interference fit of the inner surface of elastic seal cartridge 03 and core pipe 01, elastic seal cartridge 03 adopts elastomeric material to be made.Elastic seal cartridge 03 is installed in rotary hose 04 band mouthful place, and cover has fixed cover 02 in the outside, band mouth place of rotary hose 04, and the length of the joint pin 012 of core pipe 01 is less than the length of elastic seal cartridge 03, and the length of elastic seal cartridge 03 equals the length of fixed cover 02.Fixed cover 02 has spacing anchor ring 021 near an end of the connector 011 of core pipe 01, and the joint pin 011 of the interior ring core tube feeding 01 of spacing anchor ring 021 runs through.The interior ring diameter of spacing anchor ring 021 has flange 022 less than the external diameter of elastic seal cartridge 03 at the interior ring edge of spacing anchor ring 021, and the outer shroud edge of spacing anchor ring 021 links to each other with fixed cover 02.Spacing anchor ring 021, flange 022 are identical with the section thickness of fixed cover 02, and namely spacing anchor ring 021, flange 022 and fixed cover 02 are to adopt the one-body molded making of panel beating.As shown in Figure 3, axially having withheld eight on the sidewall of fixed cover 02 withholds 023, eight in muscle and withholds muscle 023 and evenly distribute around the axis of fixed cover 02.Withhold muscle 023 and adjacent two inner surfaces of withholding the part between the muscle 023 are all fitted with rotary hose 04.
A kind of production method of above-mentioned light rotary hose interface, rotary hose 04 are small-bore lightweight rotary hose, and the diameter of rotary hose 04 is 25mm.Be the band mouth place that the elastic seal cartridge 03 of 3mm inserts rotary hose 04 with thickness, as shown in Figure 4.Fixed cover 02 is enclosed within the outside, band mouth place of rotary hose 04, at this moment, the spacing anchor ring 021 on the fixed cover 02 can play position-limiting action to the elastic seal cartridge 03 in the rotary hose 04 again.Again the joint pin 012 of core pipe 01 is run through the spacing anchor ring 021 of fixed cover 02 and insert in the elastic seal cartridge 03, the joint pin 012 of core pipe 01 is inserted in the elastic seal cartridge 03 fully.At this moment, the connector 011 of core pipe 01 is fitted near an end end face of joint pin 012 and the spacing anchor ring 021 of fixed cover 02.The outer surface of fixed cover 02 sidewall is divided into arc section face eight five equilibriums and the space, each arc section face on the sidewall outer surface of fixed cover 02 is applied the pressure of withholding of 35MPa, withhold pressure all towards the axis of fixed cover 02, the arc section that is stressed is assembled facing to the place, axle center, and the part extruding between adjacent two the arc section faces that are stressed forms withholds muscle 023.In the process of withholding muscle 023 formation, adjacent two part of withholding between the muscle 023 effects of being under pressure, reduced also compresses rotary hose 04, rotary hose 04 is under pressure and compresses elastic seal cartridge 03, elastic seal cartridge 03 compresses the joint pin 012 of core pipe 01 by self strain, realizes the fixing of rotary hose 04 and core pipe 01.The pressure of 35MPa not only can make adjacent two parts of withholding between the muscle 023 be pressed on closely on the rotary hose 04, and can avoid fixed cover 02 is broken.
Because joint pin 012 interference fit of elastic seal cartridge 03 and core pipe 01, elastic seal cartridge 03 can play sealing function to the joint pin 012 of core pipe 01, and the pawl of joint pin 012 outer surface can strengthen the firmness that elastic seal cartridge 03 is connected with joint pin 012.In withhold the process that muscle 023 forms, the firmness and the sealing that are connected between the joint pin 012 of elastic seal cartridge 03 and core pipe 01 have further been strengthened.Withhold muscle 023 and adjacent two parts of withholding between the muscle 023 all compress rotary hose 04, make rotary hose 04 fixing with elastic seal cartridge 03 and core pipe 01, avoid rotary hose 04 directly to contact with core pipe 01, increase the firmness that connects, avoid because excessive rotary hose 04 and the core pipe 01 of causing of hydraulic pressure threaded off.Elastic seal cartridge 03 adopts elastomeric material, and thickness adopts 3mm, not only itself has elasticity and can strengthen sealing effectiveness; And have certain intensity, can the rotary hose 04 of flexibility be supported.Can be connected on the fire hydrant on the connector 011 of core pipe 01, also can connecting tap.
Should be understood that this embodiment only is used for explanation the utility model and is not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
