Description

A kind of sealing docking structure suitable for sewage disposal pipeline

Technical field

Pipeline technical field of sealing technology is the utility model is related to, particularly a kind of sealing suitable for sewage disposal pipeline is docked Structure.

Background technology

Most important sewage disposal is the effect for being to handle, but often the design to pipeline and quality think little of people, Especially for the transmission of sewage in sewage disposal, if sealing is bad, sewage can be caused to leak, the environment of sewage disposal is made Into pollution, due to the pipeline of sewage disposal, its needs transmits the liquid much with foreign matter, and volume varies, it is easy to pipe Road is blocked, so needing to disassemble pipeline, then the docking structure for pipeline is, it is necessary to convenient quickly plug peace Dress, and leakproofness is needed, the docking structure of the buckle pattern such as current spinner is unable to meet demand.

Utility model content

The technical problems to be solved in the utility model is in view of the above shortcomings of the prior art, there is provided one kind is suitable for sewage Handle the sealing docking structure of pipeline.

In order to solve the above technical problems, technical solution adopted in the utility model is：One kind is suitable for sewage treating tube The sealing docking structure on road, it includes male connector pipe and female pipe, and the end of male connector pipe is inserted in female pipe；The end of male connector pipe Lateral surface is covered with male connector sealable outer；Female pipe includes inner and outer tubes, and inner tube includes annular body, the annular body to The socket direction of outer tube is alternate to be extended with some inner tube fixture blocks, which, which surrounds one, has the clamp of opening and closing action, Lock ring is provided between inner tube and outer tube, lock ring is located at the free end of clamp, which is equipped with the knob for stretching out outer tube, outside The lateral surface of pipe is equipped with a groove, shakes hands to stretch out the groove out of outer tube, and the groove has the slide opening of certain length, passes through External force pulls knob, lock ring is entered or is exited between inner tube and outer tube, so that the clamp or conjunction are realized to male connector pipe end The clamping and release in portion；The knob is hinged on lock ring by torsional spring, and position limiting structure is provided between the knob and lock ring, Knob is set to be groove floor to being vertically between groove floor in scope of activities；In the free end tip inside table of interior pipe clamp block Face is equipped with clamp sealant, and the sealing surface with inner tube end contact, the sealing surface and inner tube end face are equipped with the medial surface of lock ring All it is respectively arranged with end face seal layer.

Described that limited block is equipped with the side wall of groove in above-mentioned technical proposal, knob is fallen into after overcoming the active force of tension spring In in groove, and by being stuck in the lower section of the limited block, and avoid ejecting.There is the groove sufficiently long slide opening to allow the drawing Limited block is avoided when hand sinks into groove and resets at the lower section of limited block again.

In above-mentioned technical proposal, sealing ring is equipped between the lateral surface and outer tube medial surface of the annular body.

The beneficial effects of the utility model are：By way of interior tube grip male connector pipe, the sealing docking of pipeline is realized, and And do not have to traditional buckle and spinner mode, but by the way of gasket, lock ring realizes the function of the gasket, passes through external force pair Knob is driven, and lock ring, which is plugged in, to be closed up the inner tube fixture block of clamp and surround a circle between clamp and outer tube, by public affairs The end part seal of head tube, which surrounds, completes docking.Touched in order to avoid the accident of knob, by its bending and the spacing groove in outer tube It is interior, avoid false touch.Between lock ring and inner tube, design of Sealing Structure is equipped between inner tube and male connector pipe, is had well Leakproofness.This overall structure has good leakproofness, and with easily disassembly and assembly structure, can ensure in sewage disposal There is good anti-leak to act in Pipe transfer to sewage, and quickly dismounting can be provided when dismounting and assembled When provide quickly assembling.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of sealing docking structure suitable for sewage disposal pipeline, it includes male connector pipe 1 and female pipe 2, the end of male connector pipe 1 is inserted in female pipe 2；The end lateral surface of male connector pipe 1 is covered with male connector sealable outer 3；Female pipe 2 Including inner tube 4 and outer tube 5, inner tube 4 includes annular body 6, alternate is extended with to the socket direction of outer tube 5 in the annular body 6 Some inner tube fixture blocks 7, which, which surrounds one, has the clamp 8 of opening and closing action, is set between inner tube 4 and outer tube 5 There is lock ring 9, lock ring 9 is located at the free end of clamp 8, which is equipped with the knob 10 for stretching out outer tube 5, and the lateral surface of outer tube 5 is set There is a groove 11, knob 10 stretches out the groove 11 out of outer tube 5, and the groove 11 has the slide opening 16 of certain length, passes through External force pulls knob 10, lock ring 9 is entered or is exited between inner tube 4 and outer tube 5, so that realization is opened or closed to the clamp 8 to public affairs The clamping and release of 1 end of head tube；The knob 10 is hinged on lock ring 9 by torsional spring, is set between the knob 10 and lock ring 9 Position limiting structure 12 is equipped with, makes knob 10 be 11 bottom surface of groove to being vertically between 11 bottom surface of groove in scope of activities；In inner tube The free end tip inside surface of fixture block 7 is equipped with clamp sealant 13, is equipped with and 4 end contact of inner tube in the medial surface of lock ring 9 Sealing surface, the sealing surface and 4 end face of inner tube are all respectively arranged with end face seal layer 14.
