Technical Field

The invention relates to a locking device, in particular to a novel locking snap ring for a quick connector.

Background

Along with the comprehensive use of nylon tube in vehicle chassis braking system, the quick connector that changes and connect the usefulness to the nylon tube also obtains a large amount of uses, need use the locking snap ring when quick connector locks the nylon tube, and current locking snap ring generally adopts annular slot type cylinder snap ring, and this kind of structure production efficiency is low, and the processing degree of difficulty is high, and material utilization is low.

Therefore, in view of the above, research and improvement are made for the existing snap ring structure and the deficiency thereof, and a novel locking snap ring for a quick connector is provided, so as to achieve the purpose of being more practical.

Disclosure of Invention

In order to solve the technical problems, the invention provides a novel locking snap ring for a quick connector, which aims to solve the problems of low production efficiency, high processing difficulty and low material utilization rate of the conventional snap ring.

The invention relates to a purpose and an effect of a locking snap ring for a novel quick connector, which are achieved by the following specific technical means:

the utility model provides a novel quick connector is with main part of locking snap ring is semi-closed ring (1), the ring is equipped with tension groove (7), the outside of ring is outer conical surface (2), the inboard of ring is interior conical surface (3), the below of interior conical surface (3) is down conical surface (4), tangent plane (5) and interior conical surface (3) handing-over department of down conical surface (4) are locking blade (6).

Compared with the prior art, the invention has the following beneficial effects:

the invention has simple design and high reliability, and not only ensures the normal locking function and the ring withdrawing function of the nylon tube, but also greatly reduces the process difficulty required by processing, reduces the material waste, has simple assembly and strong practicability by improving the original annular groove type cylindrical snap ring into a semi-open groove type circular snap ring.

Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

Example (b):

as shown in figure 1:

the invention provides a novel locking snap ring for a quick connector, which comprises a semi-closed circular ring (1) as a main body, wherein the circular ring is provided with a tension groove (7), the outer side of the circular ring is an outer conical surface (2), the inner side of the circular ring is an inner conical surface (3), an inverted conical surface (4) is arranged below the inner conical surface (3), a locking cutting edge (6) is arranged at the joint of a tangent plane (5) of the inverted conical surface (4) and the inner conical surface (3), a nylon tube slides into the semi-closed circular ring (1) through the inner conical surface (3) during working, the tension groove (7) is opened along with the tension groove, the nylon tube is inserted into the locking cutting edge (6), when the nylon tube moves outwards under the action of external force, the outer conical surface (2) and a pressing sleeve of the quick connector act together to generate a contraction force, the locking cutting edge (6) tightly locks the nylon tube, and when the nylon tube is disassembled, a disassembling tool slightly pushes a jacking rod forwards, the reverse conical surface (4) is enabled to prop against the quick connector fixing ring, the tension groove (7) is enabled to be opened, and the nylon tube can be rapidly drawn out at the moment.

The locking clamp ring is simple in structure, high in production efficiency, small in processing difficulty, high in material utilization rate, strong in practicability and convenient to popularize and use.

The above-described embodiment is only one of the preferred embodiments of the present invention, and general changes and substitutions by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
