Description

Hose metal connector

Technical Field

The utility model belongs to the field of hose accessories, and more specifically relates to a hose metal joint.

Background Art

A hose is a tool used to transport liquids or gases, etc. The hose generally has joints at both ends. The main function of the joint is to achieve the connection between two pipes.

Most existing hose connectors are shown in FIG. 1 , and include a stepped tube 1 having a channel 101 inside and in a stepped shape. The tail of the stepped tube 1 is connected to the hose, and the head of the stepped tube 1 is threadedly connected to a connector of another pipe by a threaded connection.

In the prior art, a hose connector similar to the above-mentioned one needs to install a sealing ring 2 on the step surface inside the step pipe 1 to ensure sealing performance. However, during the threaded connection of the two hose connectors, the connector of the other pipe will continue to rotate and abut against the sealing ring 2, causing the sealing ring 2 to be deformed and damaged due to torque, thereby resulting in poor sealing performance.

In addition, during the use of a hose such as a shower hose, the spray head often needs to be rotated, which leads to the problem that the spray head is easily loosened from the hose in the prior art.

Utility Model Content

In view of the deficiencies in the prior art, the purpose of the utility model is to provide a hose metal joint, which can prevent the sealing ring from being deformed and damaged due to torsion.

In order to achieve the above purpose, the utility model provides the following technical solutions:

A hose metal joint, comprising:

a body having a passage therein;

A mounting ring fixed to the outer wall of the body;

The outer shell is sleeved on the outer side of the body, the inner wall of which is provided with an internal thread and the inner diameter of one end of which is smaller than the outer diameter of the mounting ring;

A base, sleeved between the shell and the tail of the body, used to clamp the hose at the tail of the body;

A rotating seat is rotatably sleeved between the shell and the body;

One end of the body passes through the rotating seat and a limiting portion is provided at the passing end, and a sealing ring is installed on the outer wall of the rotating seat.

The advantages of this solution are at least that the hose is sleeved on the tail of the body and clamped on the outer wall of the body through the base, and then the shell is pushed upward. Since the shell is in the shape of a hollow cone (with a larger diameter at the top and a smaller diameter at the bottom), it will not be completely pushed out from the head of the body. After the shell is pushed out, the joint of the other pipe is directly connected to the internal thread of the shell through a threaded connection to achieve the connection of the two pipes.

During this process, since the rotating seat can rotate, the rotating seat will drive the outer shell to rotate together, thereby achieving relative fixation between the sealing ring and the outer shell, which can avoid the sealing ring being deformed or damaged due to torque.

The utility model is further configured as follows: a gasket sleeved outside the main body is movably provided between the rotating seat and the mounting ring.

The advantage of this solution is at least that the additional installation of the gasket can form a friction dislocation between the mounting ring and the rotating seat, thereby reducing the direct friction stroke between the rotating seat and the mounting ring and reducing friction.

The utility model is further configured as follows: the outer peripheral wall of the rotating seat is provided with a clearance ring groove for the sealing ring to be inserted into.

The advantage of this solution is at least that the relief ring groove plays a role of relief and limitation.

The utility model is further configured as follows: a Teflon layer is provided on the surface of the rotating seat.

The advantages of this solution are at least that the Teflon layer belongs to the prior art and has a small surface friction coefficient, which can further reduce the friction between the rotating seat and the mounting ring.

The utility model is further configured as follows: the sealing ring is provided with two.

The advantage of this solution is at least that the two sealing rings have better sealing performance.

In summary, the utility model has at least the following advantages:

1. By providing a movable rotating seat and a housing, and arranging the sealing ring on the outer peripheral wall of the rotating seat, since the rotating seat can rotate, the rotating seat will drive the housing to rotate together, thereby achieving relative fixation between the sealing ring and the housing, and avoiding the problem of deformation and damage of the sealing ring due to torsion;

2. By setting the gasket, the additional gasket can form a friction dislocation between the mounting ring and the rotating seat, reducing the direct friction stroke between the rotating seat and the mounting ring and reducing friction;

3. By providing a Teflon layer on the surface of the rotating seat, the Teflon layer belongs to the existing technology and has a small surface friction coefficient, which can further reduce the friction between the rotating seat and the mounting ring.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings.

A hose metal joint, as shown in FIG2 and FIG3, comprises:

The body 3 has a channel 101 inside thereof, and the channel 101 is used for fluid to flow through. For the convenience of explaining this solution, the two ends of the body 3 are respectively named as the head and the tail, the tail is connected to the hose 10 that has not been provided with a joint, and the head is connected to the joint of another pipeline (not shown in the figure). It is worth mentioning that the other pipeline refers to any product with a pipeline structure, such as another pipe, a shower head, a water pump outlet, etc.

The mounting ring 4 is fixed to the outer wall of the body 3 , and preferably the mounting ring 4 and the body 3 are integrally formed.

The outer shell 5 is movably sleeved on the outside of the body 3 and has a gap with the body 3, and the gap is used to install the base 6 and the mounting seat. The inner diameter of one end of the outer shell 5 is smaller than the outer diameter of the mounting ring 4, and is preferably a hollow truncated cone. When the outer shell 5 moves, it will be limited by the mounting ring 4 and cannot fall off from the head of the body 3. The inner wall of the outer shell 5 is provided with an internal thread. When the outer shell 5 moves toward the head of the body 3, the internal thread is used to cooperate with the joint thread of another pipe.

The hose metal joint further includes a base 6 which is sleeved between the shell 5 and the tail of the body 3 and is used to clamp the hose 10 at the tail of the body 3 , thereby achieving communication between the hose 10 and the body 3 .

The rotating seat 7 is rotatably sleeved in the gap between the shell 5 and the main body 3. One end of the main body 3 passes through the rotating seat 7 and is provided with a limiting portion 301 at the passing end. The limiting portion 301 is preferably a limiting ring with an outer diameter larger than the main body 3. The limiting ring is used to prevent the rotating seat 7 from falling off the main body 3.

A sealing ring 2 is installed on the outer wall of the rotating seat 7. In some preferred embodiments, two sealing rings 2 are provided. A clearance ring groove 9 is opened on the outer peripheral wall of the rotating seat 7, and the sealing ring 2 is sleeved in the clearance ring groove 9.

During installation, the housing 5 is pushed upward. Since the housing 5 is in the shape of a hollow truncated cone (with a larger diameter at the head and a smaller diameter at the tail), the tail of the housing 5 cannot be completely pushed out of the head of the body 3, and the head will be pushed beyond the rotating seat 7. After the housing 5 is pushed out, the joint of another pipe is connected to the internal thread of the housing 5 through a threaded connection to achieve the connection of the two pipes. It is worth mentioning that the joint of the other pipe is a tubular structure with an external thread, which belongs to the prior art and can be directly matched with the joint provided by this solution, and will not be described in detail here.

In order to improve the smooth rotation performance of the rotating seat 7, in some preferred embodiments, a gasket 8 sleeved on the outside of the body 3 is movably provided between the rotating seat 7 and the mounting ring 4. The addition of the gasket 8 can form a friction dislocation between the mounting ring 4 and the rotating seat 7, reduce the direct friction stroke between the rotating seat 7 and the mounting ring 4, and reduce friction. In order to further reduce the above-mentioned friction, in some embodiments, a Teflon layer can be provided on the surface of the rotating seat 7. The Teflon layer also belongs to the prior art, and its surface friction coefficient is small, which can further reduce the friction between the rotating seat 7 and the mounting ring 4, and will not be repeated here.

The working process and beneficial effects of the utility model are as follows: the hose 10 is sleeved on the tail of the body 3 and clamped on the outer wall of the body 3 through the base 6, and then the shell 5 is pushed upward. Since the shell 5 is in the shape of a hollow frustum (with a larger diameter at the top and a smaller diameter at the bottom), it will not be completely pushed out from the head of the body 3. After the shell 5 is pushed out, the joint of another pipeline is directly connected to the internal thread of the shell 5 through a threaded connection to achieve the connection of the two pipelines.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
