Abstract
The utility model discloses a kind of self-packing pipe coupling, comprise the joint body of tubulose, described joint body threaded one end is connected with lock nut, is provided with rubber ball and is positioned at the locking spring of rubber ball periphery between lock nut and joint body end; Described ball ring axial centre is provided with the through hole of inner wall smooth, and rubber ball periphery is circular arc.The utility model inserts the through hole of ball ring axial centre by pipeline, and by rubber ball inwall close fit pipeline, make lock nut, joint body end in locking process, produce axial force to rubber ball and this axial force is changed into radial force by circular arc periphery, the internal diameter reducing rubber ball improves sealability.Adopt the locking spring of rubber ball periphery to prevent lock nut and joint body from occurring thread looseness in addition simultaneously, substantially increase pipe coupling working life, reach self-packing purpose of design.
Description
Technical field
The utility model relates to a kind of joint, specifically a kind of self-packing pipe coupling.
Background technique
Inevitably often joint can be used in pipeline connection procedure; traditional joint mostly use be threaded, the technological means such as welding; but due to present improving constantly working efficiency, often use some rapid pipe joints, reach the technical purpose of fast connecting pipe.Its technological deficiency mainly existed of existing rapid pipe joint is that joint easily occurs seepy question.Study carefully its leakage cause and be seal ring socket connecting tube realization sealing, because seal ring radial direction is not subject to extra external force, often seal ring occurs a little expanding with heat and contract with cold, agingly will to leak, and this leaking appears in any side of both sides inside and outside seal ring.How providing a kind of antileaking, connecting pipe coupling is easily the object that those skilled in the art study always.
The Chinese utility model patent patent No. 201220209090.1 discloses a kind of rapid pipe joint, comprise connecting tube and link, described connecting tube is by the different bassoon of two calibers and tubule is one-body molded forms, ring apron is provided with in described bassoon, described link inside is provided with inner ring, annular groove is formed between described inner ring and link, the shape size of described annular groove and the tube wall of described bassoon suitable, described link is connected with described bassoon buckle, described inner ring is also provided with the top splenium for fixing described ring apron.This kind of rapid pipe joint not about improve sealability prevent from leaking in technical clarification or solution.
Summary of the invention
The utility model provide a kind of structure simple, prevent from leaking, connecting self-packing pipe coupling fast.
A kind of self-packing pipe coupling, comprise the joint body of tubulose, joint body two ends are equipped with outside thread, six prisms of outwardly convex are provided with in the middle of joint body, described joint body threaded one end is connected with lock nut, is provided with rubber ball and is positioned at the locking spring of rubber ball periphery between lock nut and joint body end; Described ball ring axial centre is provided with the through hole of inner wall smooth, and rubber ball periphery is circular arc.The through hole of ball ring axial centre is inserted in this kind of pipe coupling by pipeline, and by rubber ball inwall close fit pipeline, then by lock nut Screw joint body, make ball ring axially loaded and this axial force is changed into radial force by circular arc periphery, the internal diameter reducing rubber ball improves sealability.Lock nut and this screw connection structure of joint body its be not a kind of stable Placement, along with loosening often appears in use, thus ball annulate shaft can be reduced to stressing conditions, cause leaking, the utility model adopts the locking spring of rubber ball periphery to prevent lock nut and joint body from occurring thread looseness further, substantially increase pipe coupling working life, reach self-packing purpose of design.
Be equipped with arc angling as the preferred lock nut of structure, joint body end to be connected rubber ball periphery, prevent lock nut, joint body end hurts rubber ball in locking process, and improve the tightness coordinated each other, prevent from occurring water leakage phenomenon in rubber ball periphery.
The utility model inserts the through hole of ball ring axial centre by pipeline, and by rubber ball inwall close fit pipeline, make lock nut, joint body end in locking process, produce axial force to rubber ball and this axial force is changed into radial force by circular arc periphery, the internal diameter reducing rubber ball improves sealability.Adopt the locking spring of rubber ball periphery to prevent lock nut and joint body from occurring thread looseness in addition simultaneously, substantially increase pipe coupling working life, reach self-packing purpose of design.
Accompanying drawing explanation
Be illustrated in figure 1 that the self-packing pipe coupling of the utility model is main looks sectional structure schematic diagram.
Embodiment
A self-packing pipe coupling as shown in Figure 1, comprises the joint body 2 of tubulose, and joint body 2 two ends are equipped with outside thread, is provided with six prisms of outwardly convex in the middle of joint body, is convenient to the instruments such as spanner and puts forth effort locking.Joint body 2 threaded one end is connected with lock nut 1, is provided with rubber ball 3 and is positioned at the locking spring 4 of rubber ball 3 periphery between lock nut 1 and joint body 2 end.
To be connected with joint body 2 to prevent lock nut 1 and to get loose, rubber ball 3 axial centre is provided with the through hole of inner wall smooth, and rubber ball periphery is circular arc.
Be equipped with arc angling as preferred structure lock nut 1, joint body 2 end to be connected rubber ball periphery.
Claims (2)
1. a self-packing pipe coupling, comprise the joint body of tubulose, joint body two ends are equipped with outside thread, six prisms of outwardly convex are provided with in the middle of joint body, it is characterized in that: described joint body threaded one end is connected with lock nut, be provided with rubber ball between lock nut and joint body end and be positioned at the locking spring of rubber ball periphery; Described ball ring axial centre is provided with the through hole of inner wall smooth, and rubber ball periphery is circular arc.
2. self-packing pipe coupling as claimed in claim 1, is characterized in that: described lock nut, joint body end are equipped with arc angling and are connected rubber ball periphery.
