Abstract
The invention discloses a novel hose coupler. One end of a coupler body which is connected with a pipeline is conical; excircles of a positioning bushing are excircles with different diameters; the inner hole wall of the positioning bushing is inward; grooves are uniformly distributed on a circumference along the axis direction of a positioning sleeve; an elastic jack catch is made of elastic steel materials; one end of the jack catch is provided with densely covered sharp teeth; the elastic jack catch is embedded in a groove in the middle hole of the positioning bushing, and the direction of the elastic jack catch is consistent with the direction of the pipeline; the positioning sleeve is reversely sleeved on the excircle of the pipeline from the pipe opening of the pipeline to be linked; the elastic jack catch in the groove is in a compression state; because the elastic jack catch has the fit trend to the pipe opening direction, when the conical shape of the coupler body is in alignment with the pipe opening of the pipeline, a constrict nut is connected with steps of the positioning bushing; and when the constrict nut and screw threads of the coupler body are screwed tightly further, the pipeline and the components above are integrated.
Description
Technical field
The present invention relates to a kind of new-type of hose joint, particularly a kind of new-type of hose joint belongs to hydraulic pressure, pneumatic and lubrication technical field.
Background technique
In the lubrication system of hydropneumatic and electromechanical equipment, the connection between pipeline and the pipeline, and the connection between relevant pneumatic, the hydraulic element, lubricating utensil all will be used pipe joint.At present, the pipe joint that is used for above-mentioned field is special-purpose pipe joint basically, and versatility is relatively poor between the pipe of unlike material; This give to produce with maintenance and brings certain trouble, in addition, existing pipe joint with the process of pipeline connection in; Generally need carry out anticipating of hole flanging, reaming, system flange and other type in the butt joint position, so, complex process not only; Installation and maintenance are inconvenient, also have the higher scarce limit of cost.
Summary of the invention
The objective of the invention is to: a kind of new-type of hose joint is provided, overcomes the existing existing above-mentioned scarce limit of hose coupling.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of new-type of hose joint, it by fittings body, tighten nut, positioning adapter, elastic card claw, taper shape, groove, pipeline and form, fittings body has taper shape with the end that pipeline connects mutually; Wherein, conical path part is smaller with the internal diameter of pipeline, and conical large-diameter portion divides the external diameter greater than pipeline; The cylindrical of positioning adapter is two sections cylindricals that diameter is different; Form step between two sections different diameters, the inner hole wall of positioning adapter inwards, along on the circumference of the axial direction of setting sleeve; Have groove in uniform way; Elastic card claw is to be processed by the elasticity steel, under nature, is arc, is shaped on densely covered pointed tooth at an end of claw.When pipeline was connected, elastic card claw crouched in the groove in the positioning adapter intermediate hole, and the direction of elastic card claw is consistent with the Way out of pipeline; Setting sleeve to connect the mouth of pipe of pipeline, oppositely be enclosed within on the cylindrical of pipeline, at this moment; The elastic card claw that is in the groove is compressive state; Because the trend that the oriented mouth of pipe direction of elastic card claw is agreed with when the taper shape of union body is aimed at the nozzle position of pipeline, is tightened nut and is linked to each other with the step of positioning adapter; When further making the screwed of tightening nut and fittings body, then be linked to be unified integral body between pipeline and the above-mentioned part.
Beneficial effect: the present invention gives to produce with maintenance to bring convenience because after adopting technique scheme, it is better that the pipe fitting connection between the pipe of unlike material has versatility; In addition, pipe joint with the process of pipeline connection in, the butt joint position is not owing to need anticipating of hole flanging, reaming, system flange and other type; So; It is simple also to have technology, and installation and maintenance are convenient, lower-cost advantage.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Fig. 1 is a structure principle chart of the present invention.
Shown in the figure: 1, fittings body; 2, tighten nut; 3, positioning adapter; 4, elastic card claw; A, taper shape; B, groove; C, pipeline.
Embodiment
Fittings body (1) has taper shape (a) with the end that pipeline (c) connects mutually, and wherein, the path of conical (a) part is smaller with the internal diameter of pipeline (c); And the large-diameter portion of conical (a) divides the external diameter greater than pipeline (c), and the cylindrical of positioning adapter (3) is two sections cylindricals that diameter is different, forms step between two sections different diameters; The inner hole wall of positioning adapter (3) inwards; Along on the circumference of the axial direction of setting sleeve, have groove (b) in uniform way, elastic card claw (4) is to be processed by the elasticity steel; Under nature, be arc, be shaped on densely covered pointed tooth at an end of claw.When pipeline (c) when being connected; Elastic card claw (4) crouches in the groove (b) in positioning adapter (3) intermediate hole, and the direction of elastic card claw (4) is consistent with the Way out of pipeline (c), setting sleeve (1) to connect the mouth of pipe of pipeline (c); Oppositely be enclosed within on the cylindrical of pipeline (c); At this moment, the elastic card claw that is in the groove (b) is compressive state, because the trend that the oriented mouth of pipe direction of elastic card claw (b) is agreed with; When the taper shape (a) of union body (1) is aimed at the nozzle position of pipeline; Tighten nut (2) and link to each other, when further making the screwed of tightening nut (2) and fittings body (3), then be linked to be unified integral body between pipeline (c) and the above-mentioned part with the step of positioning adapter (3).
Claims (2)
1. new-type of hose joint, it is characterized in that: fittings body (1) has taper shape (a) with the end that pipeline (c) connects mutually, wherein; The path part of conical (a) is smaller with the internal diameter of pipeline (c), and the large-diameter portion of conical (a) divides the external diameter greater than pipeline (c), and the cylindrical of positioning adapter (3) is two sections cylindricals that diameter is different; Form step between two sections different diameters, the inner hole wall of positioning adapter (3) inwards, along on the circumference of the axial direction of setting sleeve; Have groove (b) in uniform way; Elastic card claw (4) is to be processed by the elasticity steel, under nature, is arc, is shaped on densely covered pointed tooth at an end of claw.
2. according to claims 1 described a kind of new-type of hose joint, it is characterized in that: when pipeline (c) when being connected, elastic card claw (4) crouches in the groove (b) in positioning adapter (3) intermediate hole; And the direction of elastic card claw (4) is consistent with the Way out of pipeline (c); Setting sleeve (1) to connect the mouth of pipe of pipeline (c), oppositely be enclosed within on the cylindrical of pipeline (c), at this moment; The elastic card claw that is in the groove (b) is compressive state; Because the trend that the oriented mouth of pipe direction of elastic card claw (b) is agreed with when the taper shape (a) of union body (1) is aimed at the nozzle position of pipeline, is tightened nut (2) and is linked to each other with the step of positioning adapter (3); When further making the screwed of tightening nut (2) and fittings body (3), then be linked to be unified integral body between pipeline (c) and the above-mentioned part.
