Description

A segmented dredge spring connector

Technical field:

The utility model relates to the technical field of hardware fittings, in particular to a segmented connector using metal springs to dredge drainage pipes.

Background technique:

At present, metal springs are widely used to dredge drainage pipes, and the dredge springs are continuously connected and lengthened through connectors to adapt to dredging longer distance pipelines.

Main technical indicators of the connector:

A. The connector must have sufficient strength to meet the needs of long-distance transmission torque.

B. The radial dimension of the connector should match the radial dimension of the dredge spring.

C. The axial dimension of the connector should be short so that the connected dredge spring can bend smoothly in the small-diameter pipe elbow.

In the past, a dredge spring connector with a T-slot was used to connect dredge springs with a diameter of 16mm and above. Its disadvantages are: due to its structure, the radial dimension is not easy to be less than 16 mm; special tools are required when the connector is separated.

Utility model content:

The purpose of the utility model is to provide a segmented dredging spring connector, which has a simple structure and can be applied to dredging springs with smaller diameters. When the connectors are separated, no special tools are needed, and the use is convenient and quick.

In order to solve the problems existing in the background technology, the utility model adopts the following technical scheme: it includes a male head, a marble, a spring and a female head. The head of the male head is provided with a radial groove, and a A pin, a spring is installed inside the pin, and the radial position of the head of the female head is provided with a hole corresponding to the pin, and the male head and the female pin are coaxially inserted through the cooperation of the pin and the hole.

The tails of the male head and the female head are both provided with a spiral part connected with the dredging spring.

The principle of the utility model is: the connector is composed of a male head and a female head. The male head and the female head are inserted coaxially to realize the connection. During the process, press down the marble to make the male head enter the female head, and make the front end of the marble enter the hole of the female head to realize the combination; when disassembling, press down the marble to make the female head come out.

The utility model has the following beneficial effects: the structure is simple, it can be applied to dredging springs with smaller diameters, and special tools are not needed when the connectors are separated, and the use is convenient and fast.

Description of drawings:

Fig. 1 is the exploded structure schematic diagram of the utility model,

Fig. 2 is the assembly structure schematic diagram of the present utility model;

Reference signs: male head 1, marble 2, spring 3, female head 4, hole 5.

Detailed ways:

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

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present utility model, and are not intended to limit the present utility model.

Referring to Fig. 1-Fig. 2, the specific embodiment adopts the following technical scheme: it includes male head 1, marble 2, spring 3 and female head 4, and the head of male head 1 is provided with a radial groove, and the inner diameter of the groove is A pin 2 is provided, and a spring 3 is installed inside the pin 2. The radial position of the head of the female head 4 is provided with a hole 5 corresponding to the pin 2. The male head 1 and the female head 4 are matched by the pin 2 and the hole 5. Coaxial plug.

Both the tails of the male head 1 and the female head 4 are provided with a spiral part connected with a dredge spring.

The principle of this specific embodiment is: the connector is composed of two parts: the male head 1 and the female head 4. The male head 1 and the female head 4 are coaxially inserted to realize the connection. During the combination of the pin 2 and the male and female heads, press down the pin 2 to make the male 1 enter the female 4, and make the front end of the pin 2 enter the hole of the female 4 to realize the combination; when decomposing, press down the pin 2 to make the female Head 4 can come out.

The above is only used to illustrate the technical solution of the utility model without limitation, other modifications or equivalent replacements made by those skilled in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, All should be included in the scope of claims of the present utility model.
