Abstract

The utility model relates to a catch hoop for pipeline connection which is particularly applied to an end-pipe connection, belonging to the machinery manufacturing technical field. The utility model comprises a circular body, a pin, a ball stud, a nut and other members, wherein the circular body comprises three ring bodies I, II, III with the same center, the same radius and the same length of circumference; three ladder-shaped grooves are arranged at the inner side of the ring bodies; the ring body is connected into a circle by the pin and the ball stud; the catch hoop is sleeved on the two end pipes; the ball stud is tightened by the nut to clamp the connector between the two pipes tightly. The utility model has the advantages of simple structure, good sealing performance, no leakage and convenient and swift usage.

Description

A kind of clip that connects end pipe

Affiliated technical field

The utility model relates to the clip that a kind of pipeline connects, and the clip of the end pipe connection of outward flanging is especially arranged, and belongs to machinery manufacturing technology field.

Background technique

At present, the Placement of pipeline is a lot, and Placements such as welding type, thread type, flange-type and clamp band type are arranged.Because pipe joint structure difference, and the Placement that adopts is also different, generally adopt clamp band type to connect for the connection of end pipe, both quick, convenient again, the clip that uses is to adopt two semiorbicular garter springs now, forms with bolt, nut screwing clamping, but can cause in actual use, the leakage of pipe coupling place because contact pressure point is inhomogeneous.

Summary of the invention

It is even that the purpose of this utility model provides a kind of contact pressure point, can not leak, and the clip of connection end pipe simple in structure.

The technological scheme that the utility model adopted is: clip includes cirque body, bearing pin, ball stud and nut etc.Cirque body is by I, II, three sections concentrics of III, same radius, constitute with the annular solid of circumference, and wherein I annular solid two ends are hinged by bearing pin and II annular solid, III annular solid respectively; The other end of II annular solid and III annular solid all is provided with an elbow that has a notch, wherein in the notch of II annular solid by the hinged ball stud of bearing pin, ball stud can be screwed by nut in two elbow notches; The inboard of three annular solids is equipped with trapezoidal groove, 15 °-22 ° of ditch slot slope α ≈, and two elbows of II annular solid and III annular solid be arranged in parallel, its spacing δ ≈ 4-8mm.

Working principle of the present utility model is: two end pipe alignment, put a seal ring in the middle of it, three annular solids wrap on the end pipe, tighten on ball stud with nut, make trapezoid-shaped trench groove face crush seal circle on the axial direction of two ends pipe of three annular solid inboards, to reach the purpose that connects and seal.

The beneficial effects of the utility model are: owing to be subjected to the pressure of the trapezoid-shaped trench groove face of three annular solid inboards on the circumference of end pipe, thereby pressure spot is more, and is evenly distributed, thus good airproof performance can not leak, convenient to use, and simple in structure.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: 1.I annular solid 2.II annular solid 3. elbows 4. bearing pins 5. ball studs 6. nut 7.III annular solids

Embodiment

As shown in Figure 1 and Figure 2, I annular solid 1, II annular solid 2 and III annular solid 7 be concentric, same radius, with three sections cirque body of circumference, and three sections cirque body are formed a complete cirque body.Wherein I annular solid 1 two ends are respectively by bearing pin 4 and II annular solid 2, III annular solid 7 is hinged, the other end of II annular solid 2 and III annular solid 7 all is provided with an elbow 3 that has a notch, the notch of II annular solid 2 is interior by bearing pin 4 hinged ball studs 5, the inboard of three annular solids is equipped with trapezoidal groove, ditch slot slope α is 20 °, spacing δ ≈ 5mm between two parallel elbows, this hoop sleeve is connected on the two ends pipe joint place that end face is provided with seal ring, again ball stud 5 is put into the notch of two elbows 3, screw with nut 6, can reach being tightly connected of two ends pipe.
