Abstract
The invention discloses a water pipe connector. According to the water pipe connector, the inclined faces of locking sleeves and locking rings are made to slide through two locking mechanisms which are arranged oppositely and through threads so as to enable hoses at the two ends to conduct expanding and compressing. The pressure resistance of expansion-type fastening connection is stronger than that of clamping hoop compression-type fastening connection. Moreover, due to the fact that materials of the hoses are used for sealing, the leakproofness is better.
Description
Technical field
The present invention relates to a kind of water pipe joint, belong to five metals field.
Background technique
Traditional water pipe joint, general by by tube socket on connecting tube, subsequently by garter spring by leather hose banding, this combination, due to the incompressibility of flexible pipe, so cannot guarantee to seal completely, is easily leaked when pressure is excessive.
Summary of the invention
The object of the invention is to: provide a kind of withstand voltage properties strong, the water pipe joint of good airproof performance.
The present invention realizes in the following way:
A kind of water pipe joint, the locking mechanism and the locking shell that comprise pair of opposing, described locking mechanism is connected with locking shell by screw thread, described locking mechanism comprises clamping sleeve, hold-down ring, described hold-down ring is cylindric, in described hold-down ring, be provided with the through hole A of circular cone shape, described clamping sleeve is circular cone shape, in described clamping sleeve, be provided with through hole B, the upper base area of described hold-down ring inner circle cone table shape through hole A is less than the area of going to the bottom of circular cone shape clamping sleeve, the area of going to the bottom of described hold-down ring inner circle cone table shape through hole A is greater than the area of going to the bottom of circular cone shape clamping sleeve,
Described clamping sleeve is embedded in the through hole A of hold-down ring, and two bottom surfaces of described hold-down ring are oppositely arranged;
Described locking shell is cylindric, and described locking outer casing inner wall is provided with internal thread, and described hold-down ring outer wall is provided with the outside thread corresponding with described internal thread, and the clamping sleeve of described two locking mechanisms compresses by relatively moving of hold-down ring.
As further innovation of the present invention, in described clamping sleeve, be also provided with cylindrical hole, the upper bottom surface of the through hole A of described cylindrical hole and circular cone shape is connected, and the sectional area of described cylindrical hole equals the upper base area of the A of circular cone shape through hole.
As further innovation of the present invention, between the opposing side of the hold-down ring of described two locking mechanisms, be provided with seal ring.
Beneficial effect: the present invention is by two locking mechanisms that are oppositely arranged, by screw thread, the inclined-plane of lock sleeve and locking ring being produced slides, thereby the flexible pipe at two ends is expanded and compressed, it is stronger that being fastenedly connected of expansion is fastenedly connected resistance to compression than the compression type of clip, and because adopt the material of flexible pipe own to seal, so seal is also better.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
In figure: 1, locking shell; 2, clamping sleeve; 3, hold-down ring.
Embodiment
Below in conjunction with accompanying drawing, be described further:
As shown in Figure 1, a kind of water pipe joint, the locking mechanism and the locking shell 1 that comprise pair of opposing, described locking mechanism is connected with locking shell 1 by screw thread, described locking mechanism comprises clamping sleeve 2, hold-down ring 3, described hold-down ring 3 is cylindric, in described hold-down ring 3, be provided with the through hole A of circular cone shape, described clamping sleeve 2 is circular cone shape, in described clamping sleeve 2, be provided with through hole B, the upper base area of described hold-down ring 3 inner circle cone table shape through hole A is less than the area of going to the bottom of circular cone shape clamping sleeve 2, the area of going to the bottom of described hold-down ring 3 inner circle cone table shape through hole A is greater than the area of going to the bottom of circular cone shape clamping sleeve 2, described clamping sleeve 2 is embedded in the through hole A of hold-down ring 3, and two bottom surfaces of described hold-down ring 3 are oppositely arranged, described locking shell 1 is cylindric, and described locking shell 1 inwall is provided with internal thread, and described hold-down ring 3 outer walls are provided with the outside thread corresponding with described internal thread, and the clamping sleeve 2 of described two locking mechanisms compresses by relatively moving of hold-down ring 3, in described clamping sleeve 2, be also provided with cylindrical hole, the upper bottom surface of the through hole A of described cylindrical hole and circular cone shape is connected, and the sectional area of described cylindrical hole equals the upper base area of the A of circular cone shape through hole, between the opposing side of the hold-down ring 3 of described two locking mechanisms, be provided with seal ring.
During use, first soft tail is passed to cylindrical hole, then clamping sleeve 2 is pressed in flexible pipe, then two-part locking mechanism is screwed in locking shell 1, by spanner, two locking mechanisms are locked, there is slippage in hold-down ring 3 and clamping sleeve 2 like this, and flexible pipe is compressed, in the hand of hydraulic pressure, directly depend on the crushing resistance of material and the flexible pipe of locking mechanism, fastening than garter spring formula, this structure coupling mechanism force is larger, and crushing resistance is also stronger.
