Description

Self-locking anti-loosing takes off quick coupling device

Technical field

The utility model relates to a kind of self-locking anti-loosing and takes off quick coupling device, belong to rapid pipe joint technical field.

Background technique

More common joint has the kind such as threaded for union and spheroid locking joint at present.

The major defect of threaded for union has: (1) is more fastening in order to connect, and thread is many, and threaded together is consuming time more; (2) in order to ensure fastening effect, need to use spanner fastening; (3) latch-up-free design, easily gets loose.

Spheroid locked type joint major defect is sleeve when surprisingly being unloaded, and joint easily gets loose.

Summary of the invention

The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of self-locking anti-loosing to take off quick coupling device, while guarantee fastening effect, reduces the consuming time of joint connection, prevent the accidental release of joint simultaneously.

According to the technological scheme that the utility model provides, described self-locking anti-loosing takes off quick coupling device, comprises male and female, and one end of male is connected with one end of female by screw thread; It is characterized in that: at the sheathed sleeve in one end that described female is connected with male, in the endoporus of sleeve, step is set, the outer peripheral surface of female is provided with step surface, sheathed spring on the step surface of female, the step in hub internal bore is withstood in one end of spring, and the other end of spring withstands the bottom surface of step surface; The outer peripheral surface of described male is provided with the first external tooth, is provided with the first internal tooth in one end of hub internal bore, the first external tooth engages with the first internal tooth; The outer peripheral surface of described female is provided with the second external tooth, is provided with the second internal tooth in the stepped inside surface of hub internal bore, the second external tooth engages with the second internal tooth.

Further, the end being connected one end in described female with male arranges jump-ring slot, in jump-ring slot, arrange jump ring.

Further, seal ring is set between described male and female.

Further, the connecting thread between described male and female has three ~ tetra-threads.

The utility model has following major advantage: the thread negligible amounts that (1) is fastening, connects comparatively quick; (2) there is self-locking design, effectively prevent joint from getting loose; (3) because have self-locking design, connection reliability is not in the degree of tightness of thread, and free-hand male being screwed into props up seal ring, can avoid use instrument; (4) compared to spheroid locked type joint, even if the utility model sleeve is surprisingly unloaded, because it is screw threads for fastening, can not get loose easily.

Embodiment

Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.

As shown in FIG. 1 to 3: described self-locking anti-loosing takes off quick coupling device and comprises male 1, female 2, sleeve 3, seal ring 4, spring 5, jump ring 6, step 7, step surface 8, first external tooth 9, first internal tooth 10, second external tooth 11, second internal tooth 12 etc.

As shown in Figure 1, the utility model comprises male 1 and female 2, and one end of male 1 is connected by screw thread one end with female 2, arranges seal ring 4 between male 1 and female 2; At the sheathed sleeve 3 in one end that described female 2 is connected with male 1, in the endoporus of sleeve 3, step 7 is set, the outer peripheral surface of female 2 is provided with step surface 8, sheathed spring 5 on the step surface 8 of female 2, the step 7 in sleeve 3 endoporus is withstood in one end of spring 5, and the other end of spring 5 withstands the bottom surface of step surface 8; The end being connected one end in described female 2 and male 1 arranges jump-ring slot, arranges jump ring 6 in jump-ring slot, prevents female 2 because the elastic force of spring 5 is separated with sleeve 3.

As shown in Figure 1, one end of described sleeve 3 endoporus is set in male 1, and the other end of sleeve 3 endoporus is set in female 2; As shown in Figure 2, the outer peripheral surface of described male 1 is provided with the first external tooth 9, is provided with the first internal tooth 10, first external tooth 9 in one end of sleeve 3 endoporus and engages with the first internal tooth 10; As shown in Figure 3, the outer peripheral surface of described female 2 is provided with the second external tooth 11, is provided with the second internal tooth 12, second external tooth 11 at step 7 internal surface of sleeve 3 endoporus and engages with the second internal tooth 12.

The utility model, when assembling, first unloads lower sleeve 3 backward, then male 1 is screwed into female 2, to Contact Seal ring 4; Then unclamp sleeve 3, make it rebound forward because of spring 5 elastic force, the first internal tooth 10 now on sleeve 3 engages with first external tooth 9 on male 1 surface, completes the locking to male 1 and female 2.

Because the outer one side of male 1 and female 2 has the first external tooth 9 and the second external tooth 11, sleeve 3 endoporus has the first internal tooth 10 and the second internal tooth 12, and inside and outside tooth engagement can prevent male 1, female 2 rotates relatively, form self-locking design, ensure that thread is fastening; Thus in the utility model, male 1 is connected with female 2 by screw thread, but only needs three or four threads to form effective cooperation.

The more existing threaded for union handling of the utility model fast, have self-locking design; Comparatively the rapid pipe joint of spheroid locking more effectively prevents accidental release.
