Description

Technical Field

[0001] The utility model relates to the technical field of fluid connectors, in particular to a fluid connector with a sealing structure. Background Art

[0002] A fluid connector is a device used to connect pipes, hoses, or other fluid transmission equipment in a fluid system. Its main function is to ensure the smooth flow of fluid in the system while providing reliable sealing and connection.

[0003] Fluid connectors in the prior art generally achieve sealing only through sealing rings, but the surface of the sealing ring will wear during the contact process with the connector, making the sealing effect no longer reliable and prone to leakage. After the sealing ring ages or wears, its sealing ability decreases, which will cause fluid leakage, which not only affects the efficiency of the system, but may also cause environmental pollution or equipment damage.

[0004] Therefore, it is necessary to design a fluid connector with a sealing structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fluid connector with a sealing structure.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fluid connector with a sealing structure, comprising a male connector and a female connector, and further comprising:

[0008] a sliding tube, slidably disposed inside the female head;

[0009] A fixing plate fixed to the outer surface of the female connector;

[0010] a spring 1, one end of which is connected to the interior of the female connector and the other end of which is connected to the sliding tube;

[0011] A sealing structure, disposed inside the male connector;

[0012] The inflatable structure is arranged on the male head, and the inflatable structure is connected to the sealing structure. When the male head is connected to the female head, the inflatable structure inflates the sealing structure.

[0013] As a preferred technical solution of the present invention, the sealing structure includes:

[0014] an annular sealing groove, formed on the inner surface of the male head;

[0015] The annular sealing member is arranged inside the annular sealing groove and has a hollow structure inside.

[0016] As a preferred technical solution of the present utility model, the inflatable structure includes:

[0017] An outer cylinder is fixed to the outer surface of the male head and has an opening at one end;

[0018] a sliding plug, sealingly and slidingly connected to the interior of the outer cylinder;

[0019] a second spring, one end of which is connected to the inner surface of the outer cylinder and the other end of which is connected to the sliding plug;

[0020] an air pipe, one end of which is connected to the outer cylinder, and the other end of which is connected to the annular sealing member;

[0021] A connecting rod has one end fixedly connected to the sliding plug and the other end extending through the opening to the outside of the outer cylinder.

[0022] As a preferred technical solution of the present invention, the outer cylinder is arranged opposite to the fixed plate.

[0023] As a preferred technical solution of the present invention, the outer surface of the sliding tube and the inner surface of the female head are in contact with each other.

[0024] As a preferred technical solution of the present invention, a fluid channel is provided inside the male head, and the cross-sectional diameter of the fluid channel is smaller than the diameter of the sliding tube.

[0025] The utility model has the following beneficial effects:

[0026] 1. After inflation, the annular seal fits tightly against the sliding tube, providing effective sealing and ensuring the sealing performance of the connection. The annular seal applies pressure to the sliding tube, enhancing the sealing effect, preventing fluid leakage, and improving system reliability.

[0027] 2. The sliding tube remains stationary after the annular seal is inflated, which avoids wear between the seal and the sliding tube and extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-5 A fluid connector with a sealed structure includes a male connector 1 and a female connector 2, and further includes: a sliding tube 3, which is slidably arranged inside the female connector 2, with the outer surface of the sliding tube 3 and the inner surface of the female connector 2 being in contact with each other, a fluid channel being provided inside the male connector 1, and the cross-sectional diameter of the fluid channel being smaller than the diameter of the sliding tube 3; a fixing plate 4, which is fixed to the outer surface of the female connector 2; a spring 5, one end of which is connected to the interior of the female connector 2 and the other end of which is connected to the sliding tube 3;

[0036] The fluid connector also includes a sealing structure disposed inside the male connector 1. The sealing structure includes: an annular sealing groove 61 formed on the inner surface of the male connector 1; an annular sealing member 62 disposed inside the annular sealing groove 61, which has a hollow structure. When the annular sealing member 62 is inflated, the annular sealing member 62 can apply pressure to the sliding tube 3. This pressure can ensure the sealing performance between the male connector 1 and the female connector 2. In addition, when the annular sealing member 62 is inflated, the sliding tube 3 is in a stationary state. This design can avoid wear between the annular sealing member 62 and the sliding tube 3.

[0037] The cam 72 is fixed to the outer surface of the male end 1 and has an opening at one end, and the outer end 71 is arranged opposite to the fixed plate 4; a sliding plug 72 is sealingly and slidingly connected to the interior of the outer tube 71; a second spring 73 is connected to the inner surface of the outer tube 71 at one end, and the other end is connected to the sliding plug 72. In the initial state, under the elastic force of the second spring 73, the sliding plug 72 is located at one end of the outer tube 71; an air pipe 74 is connected to the outer tube 71 at one end, and is connected to the annular seal 62 at the other end; a connecting rod 75 is fixedly connected to the sliding plug 72 at one end, and the other end extends to the outside of the outer tube 71 through the opening. When connecting the male end 1 and the female end 2, the staff plugs the male end 1 and the female end 2 together. When the sliding tube 3 is inserted into the interior of the male head 1, the sliding tube 3 is pressed against the inner surface of the male head 1, and the sliding tube 3 cannot move further and faces the fluid channel. As the female head 2 continues to move, the sliding tube 3 will retract into the interior of the female head 2 and squeeze the spring 1 5. Further, the female head 2 will continue to approach the male head 1, which makes the fixing plate 4 squeeze the connecting rod 75, causing the connecting rod 75 to move. When the connecting rod 75 moves, it can drive the sliding plug 72 to move. When the sliding plug 72 moves, it can press the air inside the outer tube 71 into the interior of the annular seal 62 through the air pipe 74, causing the annular seal 62 to inflate. When the male head 1 and the female head 2 are plugged together, the inner surface of the annular seal 62 will press the sliding tube 3. At this time, the annular seal 62 plays a sealing role on the connection position of the male head 1 and the female head 2, thereby ensuring the sealing performance between the male head 1 and the female head 2.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
