Description

Open Type Quick Hose Coupling

technical field

The invention relates to a fast hose connector, in particular to a connector for cable protection hoses of large equipment such as locomotives.

Background technique

As we all know, large equipment such as locomotives usually need to install a lot of cables. Since the locomotives work outdoors for a long time, the protection of cables is a problem that needs to be solved during the installation process. Locomotives generally use hoses to protect the cables to transmit power from the locomotive power compartment (two rows in the middle) to other compartments, and these protective hoses are fixed through a hose connector. When installing cables and protective hoses on locomotives, the installation space is often relatively narrow, and the locomotives run outdoors at high speed for a long time, so the problems of waterproofing and loosening must also be considered. Strong tensile strength requirements.

Contents of the invention

The present invention is to provide an open-type quick hose joint, which is used to solve the technical problem of connecting cable protection tubes on trains, and achieve the functions of convenient loading and unloading, sealing and waterproof, preventing loosening, and quick insertion and quick withdrawal.

In order to achieve the above object, the technical solution of the present invention is: an open-type quick hose connector, including a connector body and a connector cover. There are grooves on the two ends of the semi-arc cylinder respectively, and protrusions are respectively provided on the two ends of the semi-arc cylinder of the joint cover, and the rear part of the joint body and the joint cover pass through the grooves and protrusions on it Live connected to form a whole.

The inner sides of the semi-arc cylinders of the joint body and the joint cover are respectively provided with a plurality of protrusions protruding into the pipe grooves. The front part of the joint body is provided with a screw thread that is matched and connected with the locomotive.

The beneficial effects of the present invention are:

The invention adopts an open-type quick hose joint, which is small in size; in addition, when the joint cover is closed, it has a good clamping force on the pipe and can prevent loosening; at the same time, the integral structure of the joint can achieve good waterproof performance; the cover is closed and opened The problem of difficult loading and unloading of pipes has been realized by the traditional way.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 3, the open-type quick hose connector of the present invention includes a connector body 1 and a connector cover 2.

Both the rear part of the joint body 1 and the joint cover 2 are semi-arc cylinders, grooves 3 are respectively opened on the planes at both ends of the semi-arc cylinder of the joint body 1, and the two ends of the semi-arc cylinder of the joint cover 2 are flat. Protrusions 4 are respectively provided, and the rear part of the joint body 1 and the joint cover 2 are clamped and connected by the grooves 3 and the protrusions 4 to form a whole.

The inner sides of the semi-arc cylinders of the joint body 1 and the joint cover 2 are respectively provided with several protrusions 5 protruding into the pipe grooves. The front part of the joint body 1 is provided with a screw thread 6 that is matched and connected with the locomotive.

Since the joint body 1 and the joint cover 2 are both made of the same nylon material, the two are firstly injection molded by the injection molding equipment, and then the cylindrical convex part of the joint cover 2 is put into the groove part of the joint body 1, so that The opening and closing of the lid is achieved without interference. When using the open-type quick hose connector of the present utility model, first install the connector body 1 on the matching position of the locomotive through the thread 6, and then carry out threading, that is, after the cable is inserted into the pipe, it enters the next compartment through the aperture of the connector body 1 , then install the pipe to the designated position and cover the joint cover 2, thus completing the installation and use of the open-type quick hose joint; if it is unloaded, just buckle the cover by hand and take out the pipe. .

When installing, open the openings of the joint body 1 and the joint cover 2 of the joint, insert the pipe with rubber cushion into the bottom of the joint body 1, and insert the protrusion 5 inside the joint body 1 into the groove of the pipe. The opening is closed until the rectangular protrusion 4 on the side of the joint cover 2 is inserted into the corresponding rectangular groove 3 of the joint body 1 . Since the rectangular protrusion 4 and the rectangular groove 3 are tightly fitted together, the pipe is firmly clamped in the joint, thereby preventing the pipe from loosening, and at the same time, the rubber cushion is tightly connected with the inside of the joint and is not easy to loosen, thereby ensuring Water resistance. When the pipe needs to be disassembled, the pipe can be easily removed only by opening the joint body 1 and the joint cover 2 of the joint. Due to the small size of the joint, it can be easily applied in a narrow space, and a protrusion and a groove are added to the front end of the pick-up to transfer all the force during the vibration process to this part, so there is no need to consider The tensile strength of the joint does not meet the requirements.

In addition, for professionals in this industry, the open-type quick hose connector of the present invention can also be used for some other purposes, such as making the front thread openable, or this connector can also be used for drain pipes of air conditioners and washing machines The above and so on, derived many new functions and forms. Various new forms derived from these obvious combinations should also fall within the scope of protection of the open-type quick hose connector of the present invention.
