Abstract
The utility model relates to an enclasping ring spring quick pipe joint, which comprises a pipe joint main body, an enclasping ring spring, a locking device and a pipe joint shell, wherein the axis of the pipe joint main body is provided with a center hole serving as a flow channel; a pressed bearing surface of the pipe joint main body and a connected pipe is a joint surface; the enclasping ring spring is arranged in the pipe joint shell and positioned by the inner wall of the pipe joint shell; the enclasping ring spring is an annular spring providedwith an inclined opening; two sides of the inclined opening are respectively provided with positioning holes; the positioning holes respectively position a locking spinner handle and a locking positioning block of the locking device; the locking spinner handle rotates around the axis of one positioning hole; and the locking positioning block is in an inclined state. The enclasping ring spring quick pipe joint has the beneficial effects that leakage cannot occur between the enclasping ring spring and the connected pipe; and in the mounting process of the enclasping ring spring quick pipe joint, a pipe required to be connected is only required to be inserted directly, and the mounting is very convenient.
Description
Technical field
The utility model relates to a kind of annular spring quick coupling of holding tightly, may be used on the quick connection of various pitch tubes or resin compounded pipe fitting.
Background technique
The advantages such as hold annular spring rapid pipe joint tightly and compare with other collar joint, have sealing good especially, structure is relatively simple, and is applied widely, can reach working life more than 50 years, and the carrying hydrodynamic pressure is large.The technological difficulties of holding annular spring rapid pipe joint tightly are to utilize the pipe fitting insertion force to open the locking device of the hold-fast ring that has strutted.The cutting ferrule of the pipe joint of prior art and nut sleeve are after inserting fittings body on steel pipe, when screwing nut, fit with the fittings body conical surface in the cutting ferrule front end outside, inner edge is nipped in tubing equably, form the collar joint seal process, but in seal process, be fastened under the action of compressive stress of rotating nut, produce certain permanent set, and cause sealing effect to reduce the problem of even leaking.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of annular spring quick coupling of holding tightly for above-mentioned prior art, it adopts the feasible locking device of holding annular spring tightly simple in structure, open the locking device of holding annular spring tightly that has strutted with the pipe fitting insertion force, the restoring force of holding annular spring tightly by force with the pipe fitting lock ring on pipe joint body, thereby play the effect of sealing.
The utility model solves the problems of the technologies described above the technological scheme that adopts: hold the annular spring quick coupling tightly, it is characterized in that comprising pipe joint body, hold the ring type spring tightly, locking device, pipe joint shell, the axle center of described pipe joint body has center hole as runner; Pipe joint body is the mating face with the supporting plane that the tubing that is connected is pressed; Holding the ring type spring tightly installs in the pipe joint shell, and locate with the inwall of pipe joint shell, the described ring type spring of holding tightly is to have the ring-spring of oblique mouthful, described oblique mouthful of both sides have positioning hole, described positioning hole positions locking rotating handle and the lock in place piece of locking device respectively, the locking rotating handle is around the rotation of the axle center of positioning hole, and the lock in place piece is inclined.
Press such scheme, have seal groove on described mating face, seal ring is housed in seal groove.
Press such scheme, the front end of described locking rotating handle is with the boss of a bending.
The beneficial effects of the utility model are: the annular spring of holding tightly of the present utility model can not produce the effect of leakage with being connected between tubing; Hold the tubing that only needs in the installation process of annular spring rapid pipe joint required connection tightly and directly insert and get final product, install very convenient.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing, but can not consist of restriction of the present utility model.
as shown in Fig. 1-5, hold the annular spring quick coupling tightly, include symmetrical pipe joint body 1, hold ring type spring 3 tightly, locking device 4 and pipe joint shell 5, wherein, pipe joint shell 5 is connected with pipe joint body 1, and the axle center of described pipe joint body 1 has center hole as runner, pipe joint body 1 is the mating face with the supporting plane that the tubing 2 that is connected is pressed, and has seal groove on described mating face, and seal ring 6 is housed in seal groove, increases its sealability, holding ring type spring 3 tightly installs in pipe joint shell 5, and locate with the inwall of pipe joint shell, the described ring type spring of holding tightly is to have the ring-spring of oblique mouthful 9, described oblique mouthful of both sides have positioning hole 10, described positioning hole positions locking rotating handle 8 and the lock in place piece 7 of locking device respectively, the locking rotating handle is around 11 rotations of the axle center of positioning hole, the lock in place piece is inclined, the front end of described locking rotating handle is with the boss 12 of a bending, in tubing is inserted into rapid pipe joint, by pushing this boss, make the locking rotating handle rotate around the axle center, thereby make clamping block open, the restoring force of holding annular spring tightly makes the seal face close contact of tubing and agent structure, compress, thereby play the effect of sealing.
Principle of the present utility model: will hold annular support spring tightly under External Force Acting now and open and utilize locking device to lock, when inserting, connected tubing holds annular spring tightly, open locking device, holding annular spring tightly utilizes its deformation contractile force that required connected tubing is held tightly on pipe joint body, and reach sealing effect, act directly on the tubing that is connected owing to holding annular spring tightly, hold annular spring tightly and will produce a permanent shrinking stress, determined that the method holds annular spring tightly and be connected the effect that can not produce leakage between tubing.
