Abstract
The utility model discloses an elastic movable joint relating to a pipe and comprising a fixed sleeve, a movable sleeve, a sealing gasket, a nut and a rubber hose which are parts belonging to the same class, wherein an inner hole in the lower part of the fixed sleeve is provided with an internal pipe thread, the outer surface of the lower part of the fixed sleeve is hexagonal, and the middle part of the outer surface of the fixed sleeve is provided with a boss; and the outer surface of the nut is hexagonal and is sleeved from the lower side of the fixed sleeve to top, a step arranged at the lower part of the nut is blocked by the boss of the fixed sleeve, an internal thread arranged at the upper part of the nut is rotatably connected with an external thread arranged below the movable sleeve, the sealing gasket is arranged between the fixed sleeve and the movable sleeve, the middle part of the outer surface of the movable sleeve is provided with the hexagonal boss, and the outer surface of the upper part of the movable sleeve is tightly connected with the rubber hose. An upper part and a lower part of the elastic movable joint are of a symmetrical structure. The elastic movable joint has the beneficial effects that the rubber hose has certain elasticity so as not be influenced by the former pipeline installation precision, and two pipelines can be connected together through changing the length and the shape of the rubber hose during installation.
Description
Technical field
The utility model relates to a kind of pipe fitting, relates to a kind of Elastic loose joint head that on common galvanizing pipe, uses specifically.
Background technique
People be unable to do without pipeline in daily life, for example water pipe and tracheae, and it is used to every field such as engineering, colliery, weaving, electric power, boiler, machinery, military project widely.Yet pipeline again by pipe, elbow, to constituting after silk, pipe collar, threeway, union, valve, the first-class pipe fitting assembling of the fire hose.The effect of its union is the termination that connects two tubes.Usually when the design and installation pipeline, for the convenience of keeping in repair from now on, in a longer pipe road, often one or several union will be installed, particularly in the place that threeway is housed, a union must be adorned in its next door.But the pipe that in real work, runs into the loose joint two ends through regular meeting is fixed and can not moves, and gets the loose joint crown tightly, and loose joint can't be opened, and causes maintenance work to carry out.In addition, the two point-blank maybe can not intersect in intersection in piping erection, to run into two tubes through regular meeting, and the existing union of thing can not be used, and must whole preliminary engineering be done over again, and brings loss to work.
Summary of the invention
The purpose of the utility model is to remedy the defective and the deficiency of existing technology, and a kind of Elastic loose joint head is provided, and it has certain stretchability and elasticity, can the two tubes that can not correctly cross be linked together, and dismounting is all very convenient.
For realizing above-mentioned purpose; The utility model adopts following technological scheme: a kind of Elastic loose joint head; Be made up of fixed cover, movable sheath, sealing gasket, nut, sebific duct, they are a cover parts, are being provided with Internal Pipe Thread in the endoporus of fixed cover bottom described in this integrally-built Lower Half; Its underpart outer surface is a hexagonal shaped, at the middle part of its outer surface one boss is arranged; The nut outer surface is a hexagonal shaped; Nut suit from the lower direction of fixed cover; The be fixed boss of cover of the step of nut bottom blocks, and the outside thread below the internal thread on nut top and the movable sheath spins, and a sealing gasket is housed between fixed cover and movable sheath; There is an outer hexagonal boss at the middle part of movable sheath outer surface, and the outer surface on movable sheath top closely is connected with a sebific duct; The utility model two-part up and down is a symplex structure, and the Therefore, omited is to the description of upper half part.
The method for using of the utility model: on the pipeline that the fixed cover at two ends spins respectively up and down; Be contained in two sealing gaskets up and down on the fixed cover; The movable sheath at sebific duct two ends is aligned with two fixed covers up and down respectively; Spin with two nuts up and down and two movable sheaths up and down, can accomplish the butt joint of two pipelines and install.
The beneficial effect of the utility model is: because sebific duct has certain elasticity, so do not receive the influence of piping erection in early stage precision, can link together two pipelines through length and the shape that changes sebific duct during installation.
Description of drawings
Accompanying drawing is the structural representation of the utility model;
Among the figure, 1. fixed cover, 2. movable sheath, 3. sealing gasket, 4. nut, 5. sebific duct.
Embodiment
Among the figure; A kind of Elastic loose joint head; Be made up of fixed cover 1, movable sheath 2, sealing gasket 3, nut 4, sebific duct 5, they are a cover parts, in this integrally-built Lower Half, are processed with Internal Pipe Thread in the fixed cover 1 bottom endoporus; Fixed cover 1 lower external face is processed into outer hexagonal shaped, at the middle part of fixed cover 1 outer surface one boss is arranged; Nut 4 outer surfaces are outer hexagonal shaped; Nut 4 suit from the lower direction of fixed cover 1; The step of nut 4 bottoms cover 1 the boss that is fixed blocks, and the outside thread of the internal thread on nut 4 tops and movable sheath 2 belows spins, and a sealing gasket 3 is housed between fixed cover 1 and movable sheath 2; There is an outer hexagonal boss at the middle part of movable sheath 2 outer surfaces, and the outer surface on movable sheath 2 tops closely is connected with a sebific duct 5; The utility model two-part up and down is a symplex structure, and the Therefore, omited is to the description of upper half part.
