Description

A universal joint for pipes

technical field

The utility model relates to a joint, in particular to a general joint for pipelines.

Background technique

The rubber hose is made of rubber and has a certain degree of elasticity. It is suitable for conveying hydraulic fluids, such as alcohol, fuel oil, lubricating oil, emulsion, etc. It is a common connection device for chemical experiments and is often used in conjunction with other glass experimental instruments. , such as: one end of the rubber hose is set on the experimental instrument with the interface, and the other end is connected to the tap. In practical applications, due to the variety of experimental instrument interfaces, when rubber hoses are used on experimental instruments, the rubber hoses are often of different sizes and the stretchability of some hoses is poor, making the rubber hoses less versatile. , the following problems often occur: when the hose is inserted into the faucet, the hose is often not fixed tightly due to the shallow insertion of the hose, which causes the hose to be washed out by the water flow; after the rubber hose is placed on the faucet for a long time The part of the hose that covers the faucet will swell and age, and this part has to be cut off when it is used again, which will cause the entire rubber hose to become shorter and shorter during use, and eventually become unusable, which is not conducive to resource conservation. Reuse is a waste of resources; when putting the hose on the faucet, it is necessary to break the head of the hose hard, which will easily cause the tear of the rubber hose, resulting in the phenomenon that the sleeve is not tight or firm. It brings some troubles to the experiment.

Therefore, there is an urgent need for a universal rubber hose interface conversion device so that the rubber hose can be easily and firmly placed on the faucet.

Utility model content

In order to solve the above-mentioned technical problems, the utility model provides a universal joint for pipelines. The device adopts several non-return rings with different outer diameters, which can easily and firmly fit into hoses of different sizes and calibers, so as to prevent the The phenomenon that the hose is washed off by the faucet due to the lack of firmness occurs, which solves the troubles during the experiment.

In order to solve the above-mentioned technical problems, the specific technical solution adopted by the utility model is: a universal joint for pipelines, including two interfaces, respectively interface one and interface two connected with interface one; the interface one is connected to the water pipe, and the The interface 2 is connected to the hose, and the outer surfaces of the interface 1 and the interface 2 are provided with anti-slip lines; the outer wall of a section of the pipeline extending from the interface 2 to the interface 1 is also provided with several non-return rings with successively increasing outer diameters.

As a preferred technical solution of the present invention, an anti-falling baffle is also included, and the anti-falling baffle is fixed to one end of the non-return ring with the largest outer diameter.

As a preferred technical solution of the present invention, the first interface and the second interface are made of rubber.

As a preferred technical solution of the present invention, the non-return ring is made of raw rubber.

Beneficial effects of the utility model

The pipeline joint of the utility model is provided with several non-return rings with different diameters on the section of the connecting hose, which can be used for fixing hoses of different sizes; Close to the non-return groove formed between every two non-return rings. When used in the experimental device, the phenomenon that the hose is washed off by the faucet due to the loose sleeve of the hose is avoided, which solves the troubles during the experiment.

detailed description

In order to better explain the technical solution of the utility model, it will be described in detail below in conjunction with the accompanying drawings and embodiments.

Example

As shown in accompanying drawing 1 and accompanying drawing 2, a kind of universal joint for pipelines includes two interfaces, which are respectively interface one 1 and interface two 2 connected with interface one; the outer surfaces of interface one 1 and interface two 2 are provided with non-slip pattern; the outer wall of a section of the pipeline extending from the interface two 2 to the interface one 1 is also provided with several non-return rings 3 whose outer diameters gradually increase. In the actual application process, the interface 1 is consistent with the water tap and can be set on the water tap. The interface 2 2 is covered with a rubber hose for testing, which has different sizes. Therefore, when the size of the rubber hose is small, the rubber hose The hose is directly put on the anti-skid pattern of the interface 2; when the size of the rubber hose is large, the rubber hose is put on the non-return ring 3 matching its size, and the rubber hose is fixed on the corresponding There are 4 check grooves. Therefore, the universal pipe joint of the utility model avoids the direct connection between the experimental rubber hose and the faucet, and can be freely installed when the size of the experimental rubber hose does not match the size of the faucet.

In order to prevent the rubber hose from slipping when it is fixed on the non-return ring 3 with the largest outer diameter, it also includes an anti-falling baffle fixed at one end of the non-return ring 3 with the largest outer diameter.

In order to make the universal pipe joint more convenient and effective, the first interface 1 and the second interface 2 are made of rubber; the non-return ring 3 is made of raw rubber.

It should be understood that the above specific implementations of the present utility model are only used to illustrate or explain the principle of the present utility model, but not to limit the present utility model. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present utility model shall be included in the protection scope of the present utility model.
