Abstract

The invention belongs to the technical field of pipeline connectors, and in particular relates to a quick connector for a corrugated pipe. The quick connector for the corrugated pipe comprises a connector body, wherein the front end of the connector body is a connecting port for connecting other components or connecting another connector body; a connecting pipe for sleeving a corrugated pipe is arranged at the axis of the rear end of the connector body; the outside diameter of the connecting pipe is matched with the inside diameter of the corrugated pipe; a conical spring chuck is arranged on the connector body on the periphery of the connecting pipe; the small-diameter end of the spring chuck is connected with the connector body; the inner wall of the spring chuck is of a corrugated structure which is in corrugated matching with the outer wall of the corrugated pipe; a locking sliding sleeve is also arranged on the circumferential surface on the rear part of the connector body in a sleeving mode; the inside diameter of an inner hole of the locking sliding sleeve is matched with the outside diameter of the connector body, and a conical hole which is matched with the spring chuck is formed in the position, opposite to the spring chuck, of the inner hole of the locking sliding sleeve; a boss is arranged in the middle of the connector body; a reset spring is arranged between the boss and the locking sliding sleeve. The quick connector for the corrugated pipe is simple in structure, quick to connect, low in cost, and high in connecting efficiency.

Description

Quick joint of corrugated pipe
Technical field
The invention belongs to pipe coupling technical field, be specifically related to quick joint of corrugated pipe.
Background technique
Because bellows has certain elasticity, be under pressure at it, displacement or folding can be produced under axial force, transverse force or Moment, be widely used in producing and living, bellows in use need bellows connect head could be connected with miscellaneous part or be interconnected with the use of, and existing corrugated pipe connector generally all adopts the mode of screw-threaded coupling to make to realize between bellows with joint being connected locking, the complex structure of joint, cost is high, and screw-threaded coupling is quick not, time-consuming many when a large amount of connections, convenient not.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, and provide structure simple, connect quick joint of corrugated pipe fast, the low joint efficiency of cost is high.
The technical solution used in the present invention is as follows:
Quick joint of corrugated pipe, comprise joint body, described joint body front end is for connecting miscellaneous part or interconnective connecting port, axle center place, joint body rear end is provided with the connecting tube of socket bellows, connecting tube external diameter coordinates with inside diameter of bel, the joint body of connecting tube periphery is provided with the spring collet of taper, one end that spring collet diameter is little connects with joint body, spring collet inwall is the ripple struction coordinated with bellows outer wall ripple, joint body rear portion circumferential surface is also arranged with locking sliding sleeve, locking sliding sleeve bore inner diameter is with joint body major diameter fit and its endoporus and spring collet opposite position are the cone shape hole coordinated with spring collet, boss is provided with in the middle of described joint body, Returnning spring is provided with between boss and locking sliding sleeve.
Described connecting tube and bellows front port connecting part are also provided with seal ring.
Described Returnning spring normality is compressive state.
Described connection body axle center place is provided with the center hole communicated with connecting tube.
The invention has the beneficial effects as follows: adopt such scheme, to lock sliding sleeve forward slip during connection, spring collet opens, by bellows-sheathed on connecting tube, sliding sleeve will be locked reset, spring collet closes its inwall and is engaged with bellows and clamps, and the Returnning spring generation tension force of squeezed state acts on locking sliding sleeve and prevents its slip from ensure that the clamping of bellows, and seal ring then ensure that good tightness, structure is simple, connect rapidly, raise the efficiency, and cost is low.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is schematic cross-section of the present invention.
Wherein: 1 is joint body, 1.1 is connecting port, and 1.2 is boss, and centered by 1.3 hole, and 2 is connecting tube, and 3 is spring collet, and 4 is locking sliding sleeve, and 5 is Returnning spring, and 6 is seal ring.
Embodiment
Quick joint of corrugated pipe as shown in Figure 1, comprise joint body 1, joint body 1 front end is for connecting miscellaneous part or interconnective connecting port 1.1, the form of being threaded can be processed in connecting port 1.1, screw Connecting format etc., the matching of connecting port 1.1 is strong, axle center place, joint body 1 rear end is set to the connecting tube 2 of socket bellows, the center hole 1.3 that connection body 1 axle center place communicates with connecting tube 2 forms passage, its external diameter coordinates with inside diameter of bel, guiding connects and bellows locked by the spring collet 3 of the taper that the joint body 1 of pipe 2 periphery that is connected is arranged, connecting tube 2 bellows interior provide support prevent spring collet 3 from clamping time bellows distortion cause clamping loosely, and its external diameter and inside diameter of bel coordinate the seal ring 6 arranged in conjunction with itself and bellows front port connecting part again to ensure that the tightness perfected, one end that spring collet 3 diameter is little connects with joint body 1, one end that diameter is large facilitates the insertion of bellows at its opening degree of rear guarantee and is socketed with connecting tube 2, spring collet 3 inwall is the ripple struction coordinated with bellows outer wall ripple, tightness is also assures that to having clamped the effect strengthened, the bore inner diameter of the locking sliding sleeve 4 that joint body 1 rear portion circumferential surface is sheathed is with joint body 1 major diameter fit and its endoporus and spring collet 3 opposite position are the cone shape hole coordinated with the spring collet 3 of taper, cone shape hole coordinates with the conical surface of spring collet 3 and controls its opening-closing locking, and prevent locking sliding sleeve 4 from spring collet 3 slippage, boss 1.2 is provided with in the middle of joint body 1, be Returnning spring 5 between boss 1.2 and locking sliding sleeve 4, Returnning spring 5 is in squeezed state and produces active force and prevents from locking the sliding sleeve 4 mobile clamping ensureing bellows in the locked condition with locking sliding sleeve 4.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
