Abstract

The invention provides a fluid pipeline connecting assembly. An elastic protection pad is enabled to protect the front port of a pipe and also protected from being damaged due to excessive deformation when the fluid pipeline is connected. The fluid pipeline connecting assembly comprises a pipe and a bayonet socket to be mutually connected, wherein an elastic protection pad is used for protecting the front port of the pipe. The fluid pipeline connecting assembly is characterized in that an elastic claw is arranged in the bayonet socket and a positioning groove is formed on the wall of the pipe so that the elastic claw is locked in the positioning groove on the wall of the pipe to prevent the pipe from withdrawing when the pipe is inserted forward over the elastic claw during connection, and when the pipe is demounted, the elastic claw needs to be pushed open outwards to leave the wall of the pipe, in addition, a positioning ring is provided, the front end of the positioning ring is abutted against the steps of the bayonet socket and provided with a backward positioning surface so that the elastic protection pad is clamped between the front port of the pipe and the positioning surface of the positioning ring in the direction of the pipe axis under the state of completion of connection, and then the elastic protection pad is clamped to predetermined deformation degree and cannot be different due to the operation difference of the operator.

Description

Fluid line overlap-connected components
Technical field
The invention relates to fluid hose and refutes the field of connecing.
Background technique
Fluid line, for delivery of fluids such as water or coal gas, is refuted and is met place at needs, pipe insert forward in plug socket, refute connect fixing.For exempting from the front port of flow-induced corrosion pipe, elasticity protection pad need be set, connect under finishing stage refuting, on tube axial direction, elasticity protection pad is clamped between the front port and plug socket of pipe.Refuting while connecing, if pipe is inserted deeply not, elasticity protection pad is not yet clamped, fluid will infiltrate the front port of corrosion pipe, therefore operator generally can exert oneself deeply to insert to guarantee the clamped deformation of elasticity protection pad, so easily inserted deeply, cause elasticity protection pad excessively to damage because of deformation.Pipeline is refuted while connecing, and operator, owing to cannot seeing inner elasticity protection pad, is difficult to control insertion depth, also just cannot guarantee that elasticity protection pad is not because deformation excessively damages.
Summary of the invention
The invention is by allowing elasticity protection pad refute at fluid line the front port that can either protect pipe while connecing, again not because deformation excessively damages.
The present invention provides fluid line overlap-connected components, comprises and need mutually refute pipe and the plug socket connecing, and flexible protection pad, for the protection of the front port of pipe, is characterized in that:
In plug socket, be provided with elastic claw, tube wall has locating slot, so that refute while connecing, pipe inserts forward to be crossed after elastic claw, and the locating slot that elastic claw snaps in tube wall to be to stop pipe to retreat, and while tearing pipe open, elastic claw need be squeezed outwardly to be opened and leave tube wall;
Be provided with positioning ring, its front end is against the ladder place of plug socket, and has positioning surface backwards, so that connect under finishing stage refuting, on tube axial direction, elasticity protection pad is clamped between the front port of pipe and the positioning surface of positioning ring.
Pipeline is refuted while connecing, the degree of depth that pipe inserts depends on the distance of the front port from locating slot to pipe, locating slot processed before pipe is installed, the distance of the front port of itself and pipe is determined, on this basis, in response to the residing axial position of ladder of plug socket, be equipped with the positioning ring of respective thickness, refuting under the state of connecing distance between the positioning surface of positioning ring and the front port of pipe has just determined, elasticity protection pad will be clamped to predetermined deformation degree, can not distinguish to some extent because of operator's difference in operation, thereby can either protect the front port of pipe, can excessively not damage because of deformation again.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of the parts of fluid line overlap-connected components except pipe.
Fig. 2 is that fluid line overlap-connected components is refuted the rip cutting sectional view under the state of connecing.
Embodiment
From as the state of Fig. 1, from inside to outside positioning ring 1, elasticity protection pad 2, seal ring 6, hold spacer ring 7, elastic claw circle 4, unload pipe fitting 8, tamp part 9 and put into plug socket 3, then plug socket 3 is closed up, cover again antifouling cover 0, just can allow pipe forward (in figure for down) insert to refute and connect.After positioning ring 1 is put into, front end is against ladder 31 places of plug socket 3, and positioning ring 1 stretches out backwards and forms side block portion 11 from positioning surface 12 sides.Elasticity protection pad 2 is placed on the positioning surface 12 of positioning ring 1, fits with the side block portion 11 of positioning ring 1 in its first side 21, fits with the sidewall 32 of plug socket 3 in its second side 22.
Refuting with plug socket 3 pipe 5 connecing can be stereoplasm tube, can be also flexible plastic pipe, after insertion as shown in Figure 2.Refute while connecing, pipe 5 inserts after the elastic claw 45 of crossing on elastic claw circle 4 forward, elastic claw 45 snaps in the locating slot 54 of tube wall 50 to stop pipe 5 to retreat, be to refute and connect finishing stage: on tube axial direction, elasticity protection pad 2 is clamped to predetermined deformation degree between the front port 51 of pipe 5 and the positioning surface 12 of positioning ring 1, can not distinguish to some extent because of operator's difference in operation, thereby can either protect the front port 51 of pipe 5, can excessively not damage because of deformation again; In caliber direction, elasticity protection pad 2 is limited between the side block portion 11 of positioning ring 1 and the sidewall 32 of plug socket 3, can not skid off from side; Seal ring 6 is clamped between tube wall 50 and the sidewall 32 of plug socket 3, and on tube axial direction, seal ring 6 is between the locating slot 54 of tube wall 50 and the front port 51 of pipe 5.
Tear when pipe open, need to take out antifouling cover 0, then with instrument, push up forward and unload pipe fitting 8, thereby elastic claw 45 is unloaded pipe fitting 8 sinciputs, squeeze to open outwardly simultaneously and leave tube wall 50, pipe 5 can exit.
