Abstract
The utility model relates to a burke hydraulic pressure soft tube assembly and consists of a connector core(1), a connector cover(2), a connector lock net(3) and a soft tube(4); wherein, the lock net(3) is sheathed on the front end of the connector core(1). The outer wall of the connector core(1) is provided with an annular socket(7) and the inner wall of the connector cover(2) is correspondingly provided with a ring shaped tooth like a manger(8). The soft tube(4) is sheathed on the connector core and the connector cover(2) is burked on the soft tube(4). The utility model is characterized in that the outer wall of the front of the connector core(1) is provided with a ring shaped double trapezoid convex plate(5). The inner wall of the connector cover is correspondingly provided with an annular double trapezoid socket(6). As the annular double trapezoid convex plate is additionally arranged on the outer wall in the front end of the connector core and the annular double trapezoid socket is correspondingly arranged on the inner wall of the connector cover, the anti pulling capability of the hydraulic pressure soft tube assembly is enhanced as the steel wire layer is pressed into the annular double trapezoid socket to make a distortion partly as an inverted S.
Description
Technical field:
The utility model relates to hydraulic pressure and pneumatic gearing system field, and the transmission part that uses in the hydraulic equipment is meant hydraulic hose assembly especially.
Background technique:
Hydraulic hose assembly is widely used in military affairs, space flight and national economy every field at present, and annual to have taken off the loss that falls to causing quite serious because of hose coupling.Hydraulic hose assembly is the position of the most easily breaking down in the Hydraulic Power Transmission System.The fastening-pressing type hose coupling comprises JB1885-77A type (welding type), JB1886-77B type (FERRULETYPE), JB1887-77C type (flared type).The fastening-pressing type hose coupling has directly been continued to use to 1988 since 1977 carry out, after change NBS into, standard code is GB/T9065.1-9065.3-1988, model is divided into welding type hose assembly, FERRULETYPE hose assembly, flared type hose assembly.Wire braided hose standard code: GB/T3683-1992.The producer that produces the fastening-pressing type hose assembly at present is most of by above-mentioned standard production.
Above-mentioned hydraulic hose assembly major defect
1) capacity of resisting impact load is low, and regulation acceptable product impulse test should not be lower than 200,000 times in the NBS, and Japan mark advances JISB8360-1979 regulation fastening-pressing type rubber hose coupling impulse test and should not be lower than 400,000 times.
2) resistance to plucking takes off a little less than the ability, existing hydraulic hose assembly pull-off ability power, be that the pressure that is abutted against a core and joints sleeve squeezing tube is realized, it is little and lack that joints sleeve is withheld hose length, if strengthen the amount of withholding, improve resistance to plucking and take off ability, but because of the strength of joint core limited, and produce vertically depression, can cause leakage; If the amount of withholding is little, resistance to plucking takes off ability with decline.
Summary of the invention:
The purpose of this utility model provides a kind of capacity of resisting impact load, resistance to plucking takes off the strong Burke Type Hydraulic Hose Assembly of ability.
The utility model provides a kind of Burke Type Hydraulic Hose Assembly, comprise joint core, joints sleeve, joint locknut and flexible pipe, wherein, the joint lock sheath is at joint core front end, be characterized in: other increase of front end outer wall at the joint core has the two ladder type boss of annular, has annular two ladder type grooves in the corresponding increase of joints sleeve inwall.
Beneficial effect:, have annular two ladder type grooves in the corresponding increase of joints sleeve inwall owing to have the two ladder type boss of annular in other increase of front end outer wall of joint core.When assembling, in the two ladder type grooves with the cover of the steel wire floor press-in connector in the flexible pipe, short its local generation distortion is down " S " shape again, thereby the resistance to plucking ability of taking off of hydraulic hose assembly is strengthened.

Embodiment:
See Fig. 4～Fig. 6, the utility model is a kind of Burke Type Hydraulic Hose Assembly, comprise joint core 1, joints sleeve 2, joint locknut 3 and flexible pipe 4, wherein, joint locknut 3 is enclosed within joint core 1 front end, joint core 1 outer wall has annular groove 7, joints sleeve 2 inwall correspondences and has the annular dentation groove 8 of crouching, be with flexible pipe 4 on the joint core 1, the flexible pipe 4 outer joints sleeves 2 of having withheld, it is characterized in that: the front end outer wall at joint core 1 has the two ladder type boss 5 of annular, has the two ladder type grooves 6 of annular in joints sleeve 2 inwall correspondences.
During assembling, a part is peelled off with the flexible pipe outer layer glue by preceding elder generation, again the flexible pipe hose lining is peelled off a part.Before withholding, joint core and flexible pipe inner glue layer junction plane are coated with layer of adhesive, withhold then to strengthen anti-leakage ability.
Claims (1)
