CN203784501U - Dual-lug pole-less clamp - Google Patents

Abstract

The utility model relates to a dual-lug pole-less clamp which is a mutually nested hoop. A connecting buckle and a self-locking buckle are respectively arranged on the mutual nesting position of an outer rim ring of the hoop. Two clamping lugs are symmetrically arranged on the hoop, and a guiding groove is arranged on the inner embedding ring of the hoop at a position corresponding to the mutual nesting position of the hoop inner ring of the clamping lugs. An inward guiding convex rib is arranged on the outer embedding ring, and the guiding convex rib and the guiding groove are in mutual interlocking in a guiding and cooperating way. A guiding convex rib and a guiding groove are respectively arranged on the joint position of the clamp and the inner rim hoop, and the guiding convex rib and the guiding groove are in mutual interlocking in a guiding and cooperating way, which prevents damage of the hoop, and improves the seal performance of the internal diameter of the hoop for a clamped pipe.

Description

The electrodeless clip of a kind of ears

Technical field

The utility model belongs to mechanical field, relates to pipeline connecting parts clip, the electrodeless clip of especially a kind of ears.

Background technique

In the larger-size pipeline of reducing connects, what conventionally adopt is electrodeless clip, and the reason that adopts electrodeless clip is to be exactly that the reducing size of institute's connecting pipeline is larger, and other clips cannot be realized connection.At present, inorganic clip is generally and adopts common clip form, and clamping force is less, easily comes off.In addition, after clamping, easily there is clip distortion in existing inorganic clip, and therefore the sealing of internal diameter and pipeline is poor.

Model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of clamping force is large, the electrodeless clip of ears of internal diameter good airproof performance.

The purpose of this utility model is achieved through the following technical solutions:

The electrodeless clip of a kind of ears, it is a mutually nested garter spring, be shaped with respectively at the mutually nested position of garter spring outer rim and connect buckle and self-locking buckle, it is characterized in that: on garter spring, symmetry is shaped with two clamping ears, on the interior capel of the garter spring at the mutually nested position of garter spring inner edge of correspondence clamping ear, be shaped with a direction recess, on capel, be shaped with outside an inside guiding convex tendon, this guiding convex tendon and direction recess mutually lead and coordinate interlocking.

And, be two groups at the made connection buckle in the mutually nested position of garter spring outer rim and self-locking buckle.

Advantage of the present utility model and good effect are:

1, this clip is respectively shaped with a clamping ear in the symmetry up and down of garter spring, therefore can realize two-way clamping, and clamping force is larger, has avoided the loosening and distortion of clip.

2, this clip is shaped with respectively a guiding convex tendon and a direction recess at the garter spring handing-over position of inner edge, this guiding convex tendon and direction recess mutually lead and coordinate interlocking, not only avoid the distortion of garter spring, also improved the sealability of garter spring internal diameter to clamped pipeline simultaneously.

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the right elevation of Fig. 1;

Fig. 4 is the perspective view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; The present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.

The electrodeless clip of a kind of ears, is a mutually nested garter spring 5, is shaped with respectively connects buckle 1 and self-locking buckle 2 at the mutually nested position of garter spring outer rim, and this connection buckle and self-locking card button are respectively upper and lower two groups.

Innovative point of the present utility model is:

Respectively be shaped with in the upper and lower parts of garter spring and on one, clamp ear 3 and lower clamping ear 6, at the wherein mutually nested position of garter spring inner edge of a clamping ear of correspondence, on the interior capel of garter spring, be shaped with a direction recess 7, on the outer capel of garter spring, be shaped with an inside guiding convex tendon 4, this guiding convex tendon and direction recess mutually lead and coordinate interlocking, realize thus the guiding locking of garter spring, avoided the loosening and distortion of clip, also improved the sealability of garter spring internal diameter to clamped pipeline simultaneously.

This clip also can only be made a clamping ear.

Claims (2)

1. the electrodeless clip of ears, it is a mutually nested garter spring, be shaped with respectively at the mutually nested position of garter spring outer rim and connect buckle and self-locking buckle, it is characterized in that: on garter spring, symmetry is shaped with two clamping ears, on the interior capel of the garter spring at the mutually nested position of garter spring inner edge of correspondence clamping ear, be shaped with a direction recess, on the outer capel of garter spring, be shaped with an inside guiding convex tendon, this guiding convex tendon and direction recess mutually lead and coordinate interlocking.

2. the electrodeless clip of ears according to claim 1, is characterized in that: be two groups at the made connection buckle in the mutually nested position of garter spring outer rim and self-locking buckle.
