The anti-releasing hose joint is characterized in that a circumferential anti-releasing groove is arranged on the outer side of the core bar middle portion, and a circumferential bump corresponding to the groove is arranged on the inner side of the jacket. Alternately, a circumferential anti-releasing bump is arranged on the outer side of the core bar middle portion, and a circumferential groove corresponding to the bump is arranged on the inner side of the jacket. The anti-releasing hose joint has the advantages that the anti-releasing hose joint is convenient to use and is safe and reliable, the hose is not easy to pull off after being fastened with the joint, the quality of a product is guaranteed, potential safety hazards are stopped, and the anti-releasing hose joint is mainly used for rubber hoses reinforced by steel wires.
Description
Technical field
The utility model relates to a kind of pipe joint, and particularly a kind of rubber hose is with preventing the pull-off pipe joint.
Background technique
Before rubber hoses with wire reinforced hydraulic type comes into operation need to metal joint be combined into hose assembly then could with equipment connection, the assembly joint mainly divides two-part: core bar and overcoat, it is inner that core bar inserts flexible pipe, overcoat is enclosed within the flexible pipe outside, crimping equipment by special use shrinks overcoat the combination that realizes flexible pipe and metal joint, present this compound mode is had relatively high expectations to the physical property of sebific duct rubber layer especially inner glue layer, if in use inner glue layer does not reach requirement, produce plastic deformation because the time that is stressed is long when larger, be easy to produce joint pull-off phenomenon, larger potential safety hazard is arranged.
Summary of the invention
The utility model provides a kind of rubber hose esy to use, safe and reliable with anti-pull-off pipe joint in order to remedy the deficiencies in the prior art, can guarantee to be difficult for pull-off after flexible pipe and joint are withheld, and guarantees quality of product, stops simultaneously potential safety hazard.
The utility model is achieved by the following technical solution:
Rubber hose of the present utility model is with preventing the pull-off pipe joint, comprise the core bar and the overcoat that cooperatively interact, it is inner that core bar inserts flexible pipe, overcoat is enclosed within the flexible pipe outside, be followed successively by from front to back core bar head, core bar middle part and core bar afterbody on the core bar, its special way is: the outside, core bar middle part is provided with the groove of anticreep along the circumferential direction, and the overcoat inboard is provided with the projection along the circumferential direction of respective slot.Perhaps, the outside, core bar middle part is provided with the projection of anticreep along the circumferential direction, and the overcoat inboard is provided with the groove along the circumferential direction of corresponding projection.
Preferred version is that the groove top at described core bar middle part has been provided with the chamfering of importing effect near core bar afterbody place.
The groove subtended angle at described core bar middle part is 40 °-90 °.
The described outer projection that puts is trapezoidal tooth, the wide little 1mm of recess width than the core bar middle part of the crest of trapezoidal tooth, and the tooth base angle is 105 °-130 °.
The chamfering of the groove top at described core bar middle part is 10 °-45 °.
The beneficial effects of the utility model are, and are esy to use, safe and reliable, can guarantee to be difficult for pull-off after flexible pipe and joint are withheld, and guarantee quality of product, stop simultaneously potential safety hazard, are mainly used in rubber hoses with wire reinforced hydraulic type.
Description of drawings
Fig. 1 is structural representation of the present utility model.Fig. 2 is the core bar schematic representation, and Fig. 3 is the overcoat schematic representation.
Among the figure, 1 core bar head, 2 core bar afterbodys, 3 core bars middle part, 4 overcoats, 5 core bars, 6 outer glue-lines, 7 steel wire reinforcement layers, 8 inner glue layers, 9 grooves, 10 projections.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
The anti-pull-off pipe joint of rubber hose of the present utility model comprises the core bar 5 and the overcoat 4 that cooperatively interact, and it is inner that core bar inserts flexible pipe, and overcoat is enclosed within the flexible pipe outside, the overcoat contraction is reached the combination of realization flexible pipe and metal joint by the crimping equipment of special use; Be followed successively by from front to back core bar head 1, core bar middle part 3 and core bar afterbody 2 on the core bar, the outside, core bar middle part is provided with the groove 9 of anticreep along the circumferential direction, and the overcoat inboard is provided with the projection along the circumferential direction 10 of respective slot.Perhaps, the outside, core bar middle part is provided with the projection of anticreep along the circumferential direction, and the overcoat inboard is provided with the groove along the circumferential direction of corresponding projection.
Anti-pull-off joint core bar head 1 is that the attachment portion can be any form, and such as A type, C type, H type, K type, F type etc., diagram is take the K type as example; Core bar afterbody 2 is seal sections, has a lot of fish scale button, and generation cold flow after glue is squeezed in the sebific duct is filled into and realizes sealing in the groove of fish scale button; Joint middle part 3 anti-pull-off sections are main distinctions of the utility model and ordinary couplings, be made of one U-shaped groove, groove depth is about according to the specification difference, and groove subtended angle A is about 40 °-90 °, preferably 60 °, groove top outside diameter d 2 is than the large 0.5mm-1mm of framework layer internal diameter.For ease of the sebific duct of packing into, groove top is provided with chamfering B near core bar afterbody place and is about 10 °-45 °, and preferably 30 °, play the importing effect, the wide L1 of groove bottom is 4-6mm usually.
Anti-pull-off joint is enclosed within outward on the basis of ordinary couplings overcoat has increased the together trapezoidal tooth corresponding with the groove of core bar, the wide L2 of the crest of trapezoidal tooth is than the little 1mm of core bar recess width L1, tooth base angle C is 105 °-130 °, preferably 120 °, increase can affect the assembling of overcoat the time when tooth is long again, can increase the d3 size, the size of d3 part indentation is greater than the long deficiency of d4 compensation tooth when withholding, guarantee that the flose wire enhancement layer tightly is pressed in the groove of core bar, d3 is than the large 1-5mm of d4 usually.
Peel sebific duct inner glue layer 8 off slightly be longer than L3 one section during use, the inside of flose wire enhancement layer 7 is exposed, peel the outer glue-line 6 of sebific duct off slightly be longer than L4 one section, the outside of steel wire reinforcement layer is exposed, this moment, the front end of sebific duct only was left the steel wire reinforcement layer, the joint overcoat is enclosed within the sebific duct termination of having shelled inside and outside glue, then the joint core bar is inserted, use crimping equipment to require outer cover locking according to interior glue decrement, this moment, the steel wire reinforcement layer was subjected to the compressing of the trapezoidal tooth of overcoat, enter the U-shaped groove on the core bar, realize the anti-pull-off function of pipe joint.
