Abstract

The utility model discloses a pipe ferrule for pipe fitting connection, which comprises a pipe ferrule seat, a pipe ferrule cover, a pipe ferrule core and a targeting ring gasket. The pipe ferrule core inserts a bell mouth of the pipe ferrule seat; the targeting ring gasket inserts the pipe ferrule seat with the convex ribs facing an opening of the pipe ferrule seat; the pipe ferrule cover connects with the pipe ferrule seat through the screw. A double pipe ferrule, a elbow pipe ferrule, a three-way pipe ferrule, a four-way pipe ferrule or a multiple-way pipe ferrule are produced by changing shape of a thin tube fitting of the pipe ferrule seat. The utility model possesses advantages including a compact structure, less components, tolerance in damage, good sealing performance, and ability of connecting flexible and rigid pipefittings, firm connection, and convenience in dismounting and extensive application. The model is applicable for flexible brake connection of all kinds of pipefittings.

Description

Pipe fitting connects pipe collar

Affiliated technical field

The utility model relates to a kind of pipe fitting connection pipe collar that extruding type connects between pipe fitting that is used for.

Background technique

Connection between the pipe fitting is very common a kind of demand in producing, living, although it is very convenient to adopt spiral to connect, but some pipe fitting does not have screw thread, and the field fabrication of screw thread usually do not satisfy the requirements again, adopt this moment the extruding type pipe fitting connect pipe collar connect then convenient especially.Existing extruding type pipe fitting connects pipe collar and mainly contains following two kinds: 1. jackscrew type, and two pipe boxes connect with the jackscrew extruding, and shortcoming is that pipe fitting is yielding, and screw thread is fragile.2. wedge shape slope surface, its tube head are that branch wedge shape such as disjunctor and inner conical gland constitute, and its shortcoming is to have only the top contact, and area of contact is little, connect insecurely, easily become flexible, more than two kinds do not possess sealing.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of and is connected firmly, easy accessibility, compact structure, favorable sealing property, purposes comparatively widely the extruding type pipe fitting connect pipe collar.

The technical scheme in the invention for solving the technical problem is: this pipe fitting connects pipe collar and is made up of band shoe, pipe collar lid, pipe collar core, guiding gasket ring.Band shoe is made of the tube head of thick, thin two concentric one, and extra heavy pipe head outer wall is threaded, and inwall is tubaeform for extending out, and the outer end wall mouth connects the straight tube that has the axial gap of five equilibrium on the sidewall.The tubule head is the straight tube that outer wall contains six sides, and it is close that the internal diameter of its mouth of pipe and extra heavy pipe head inwall loudspeaker are chewed diameter.

Pipe collar lid profile is similar with the screw top jar lid, and lid center, the end has circular hole, and the screw thread of its inwall and the screw thread on the band shoe are complementary, and its outer wall is hexagonal shaped.

The pipe collar core is that a bit of conical pipe and exterior edge face have the straight tube of protruding umbrella cover shape to connect and compose, and tapering is consistent with the tubaeform tapering of band shoe inwall, the staggered axial stretching gap that has five equilibrium in pipe collar core two ends, and its place, flexible mouthful of limit remains with V-type and connects thin slice.

The guiding gasket ring connects and composes for pipe always and big planchet, and big planchet diameter is slightly less than the internal diameter of pipe collar lid, and straight pipe end face is recessed umbrella cover shape, and directly circular tube external wall has the arc convex tendon of five equilibrium.

More than assembly relation between each parts be: the pipe collar core inserts in the horn mouth of band shoe, and the gap that the convex tendon of guiding gasket ring aligns on the band shoe inserts in the band shoe, and the pipe collar lid is connected with the band shoe spiral.

When connection pipe fitting is flexible pipe, can outwards draw the pipe that an outer wall has the Drop-proof bulge loop at the loudspeaker place of chewing of band shoe inwall.

Change the shape of band shoe tubule head, can make multiple new pipe fitting and connect pipe collar.The tubule head of two pipe collars docks mutually, then forms two-tube hoop.The tubule head of two pipe collars is made elbow, then can make the elbow pipe collar.The tubule head of three pipe collars is made threeway, then can make the threeway pipe collar.The tubule head of four or more pipe collar is made four-way or multinomial logical, then can make four-way pipe collar or multinomial siphunculus hoop.

The beneficial effects of the utility model are that compact structure, parts are few, and it is not fragile, good seal performance, can connect the soft or hard pipe fitting, be connected firmly, easy accessibility, purposes is very extensive, can make pipe fitting and connect two-tube hoop, elbow pipe collar, threeway pipe collar, four-way pipe collar and multinomial siphunculus hoop, is suitable for the flexible connection between various pipe fittings.

Specific embodiment

Example 1

As Fig. 1, Fig. 2, shown in Figure 3, pipe fitting connects pipe collar (28) and is made up of band shoe (1), pipe collar core (2), guiding gasket ring (3), pipe collar lid (4).

Band shoe (1) is made of tube head (5), (6) of two concentric one of thickness, extra heavy pipe head (5) outer wall is threaded (7), inwall (8) is tubaeform for extending out, the outer end wall mouth connects the straight tube (10) that has the axial gap of five equilibrium (9) on the sidewall, tubule head (6) is orthohexagonal straight tube for outer wall contains, and it is close that the loudspeaker of the internal diameter of the mouth of pipe and extra heavy pipe head inwall are chewed diameter.

Pipe collar core (2) is a bit of conical pipe (11), there is the straight tube (13) of protruding umbrella cover shape (12) to connect and compose with the exterior edge face, tapering is consistent with the tubaeform tapering of band shoe (1) inwall (8), staggered axial stretching gap (14), (15) that have five equilibrium, pipe collar core two ends, its place, flexible gap limit remains with V-type and connects thin slice (16), it manufactures employed material can select metal, nonmetal according to the condition of connection pipe fitting institute conveying material, and rigidity or elastic material are made.

Guiding gasket ring (3) connects and composes for pipe (17) always and big planchet (18), and big planchet diameter is slightly less than the internal diameter of pipe collar lid (4), and straight pipe end face is a recessed umbrella cover shape (19), and directly circular tube external wall has the arc convex tendon (20) of five equilibrium.
