There is a fitting as shown in figure 1 which includes a fitting body 11 and sealing means 12. The fitting body 12 has a cavity 13 for receiving the sealing mechanism 12, the cavity 13 being used for mounting the sealing mechanism 12. It is worth mentioning that the cavity 13 is a vertical smooth surface, so when the sealing mechanism 12 is installed in the cavity 13, since the sealing mechanism 12 is not inserted into the cavity 13 by pressing, there is a risk of leakage of the pipeline, and the joint is not reliable in sealing. In addition, in order to prevent the sealing mechanism 12 from falling off, a sealing member needs to be added to the joint body 11, which results in an additional process for the joint body 11, which increases the processing cost of the joint body 11. Finally, the items used for sealing are generally not very often removable, and the above-mentioned joints are removably connected, which increases the time for manually assembling the joints and is therefore cumbersome.

In view of the above, there is a need for a connector that has good sealing properties, low cost, and is easy to assemble.

Based on the technical problem, the application provides a joint, wherein, joint structure is simple, does not relate to complicated manufacturing process and expensive material, has higher economic nature, simultaneously, to the producer, the joint that this application provided easily produces, and low cost, more is favorable to controlling manufacturing cost, further is favorable to product popularization and use.

Schematic joint

A fitting is illustrated in fig. 2-5 as being used to connect tubing to seal the tubing.

Specifically, the fitting includes a fitting body 11 and a seal assembly 15. The seal assembly 15 is sleeved on the joint body 11 and is used for sealing one end of the joint body 11.

Further, the joint body 11 has a connecting end 111, the connecting end 111 has a first cavity 112 and an opening 113, the opening 112 is communicated with the first cavity 112, and the first cavity 112 is used for accommodating the sealing assembly 15.

Further, in the present invention, as shown in fig. 4, the inner wall of the first receiving chamber 112 is a vertical smooth surface before assembling, and when the sealing assembly 15 is placed in the first receiving chamber 112, since the sealing assembly 15 is not inserted into the first receiving chamber 112 by pressing, the sealing assembly 15 may have a risk of loosening, which may result in leakage of the pipeline. Therefore, to improve this drawback, as shown in fig. 1, when the seal assembly 15 is installed in the first cavity 112 and the seal assembly 15 is installed in the first cavity 112, the peripheral side of the connecting end 111 is pressed by an external mold, and the external mold deforms the peripheral side wall of the connecting end 111 in a buckling manner, so that the peripheral side wall of the connecting end 111 is bent inward, which causes the opening 113 to shrink, and finally the seal assembly 15 is defined in the first cavity 112. More particularly, the sealing assembly 15 can be effectively and firmly fixed in the first accommodating cavity 112 by buckling the peripheral side wall of the connecting end 111, so as to achieve the purpose of sealing. It should be noted that, in this way, there is no need to use a sealing member for fixing one end of the sealing assembly 15, which greatly reduces the cost of the joint, and the addition of a sealing member for fixing one end of the sealing assembly 15 adds a process to the joint body 11, increases the processing cost of the joint, and is troublesome and not conducive to production.

It will be appreciated by those skilled in the art that the first volume 112 is embodied as a cylindrical volume.

Further, in the present invention, as shown in fig. 4 and 5, the connecting end 111 has a first force-bearing surface 1111, and the first force-bearing surface 1111 is used for necking the opening 113 by means of external mold pressing. It should be noted that, when the first force-bearing surface 1111 is deformed by an external force, since the wall thickness of the opening of the first cavity 112 is thinner, when the first force-bearing surface 1111 is deformed by the external force to cause the opening 113 to shrink, the inner wall of the first cavity 112 is deformed accordingly. Further, when the opening 113 is constricted, the seal assembly 15 mounted in the first cavity 112 is defined in the first cavity 112. Since the opening 113 is deformed to reduce the diameter of the opening 113, the sealing assembly 15 cannot be separated from the first cavity 112.

Further, the connecting end 111 has a second force-bearing surface 1112, and the second force-bearing surface 1112 is configured to bend an inner wall of the first cavity 112 by external mold pressing, so that the inner wall of the first cavity 112 tightly fits the surface of the sealing assembly 15, wherein the inner wall of the first cavity 112 seals the sealing assembly 15 by bending inward and tightly fitting the surface of the sealing assembly. It should be noted that when the second force-bearing surface 1112 is deformed by an external force, since the wall thickness of the opening of the first cavity 112 is thinner, when the second force-bearing surface 1112 is deformed by the external force, the opening of the first cavity 112 is deformed accordingly. It should be noted that the second force-bearing surface 1112 is pressed obliquely downward, so that when the first force-bearing surface 1111 is deformed by a force, the inner wall of the opening of the first cavity 112 is bent by the deformation of the second force-bearing surface 1112, and the inner wall of the first cavity 112 is tightly attached to the surface of the sealing assembly 15 to seal the sealing assembly 15, thereby improving the sealing performance of the joint.

It should be noted that, as will be understood by those skilled in the art, the first force-bearing surface 1111 shown in fig. 4 is a surface that is not deformed by a force, and the first force-bearing surface 1111 shown in fig. 5 is a surface that is deformed by a force. The second force-receiving surface 1112 shown in fig. 4 is a surface before being deformed by a force, and the second force-receiving surface 1112 shown in fig. 5 is a surface after being deformed by a force.

Further, the joint body 11 further includes an insertion end 113, and the insertion end 113 is used for connecting a pipeline. In order to ensure the sealing performance when the insertion end 113 is connected with the pipeline, the insertion end 113 is in threaded connection with the pipeline so as to enhance the sealing performance of the joint.

Further, the insertion end 113 extends inward to form a second cavity 114, and the second cavity 114 is used for accommodating the pipeline.

Further, a flow passage 115 is formed between the first cavity 112 and the second cavity 114, wherein the flow passage 115 has a buffer area 1151, and the buffer area 1151 is used for reducing the pressure applied to the flow passage 115 during drainage, so as to prevent the joint from being cracked due to too much pressure applied to the flow passage 115.

Further, the sealing assembly 15 further includes a sealing member 151, an inner core 152, a spring 153 and a filtering net 154, wherein the sealing member 151 is mounted in the mounting groove 1121. Further, the core 152 is sleeved on the sealing member 151. Further, the spring 153 has one end connected to the inner core 152 and the other end connected to the filter screen 154. Further, the filter screen 154 is installed at the bottom of the first cavity 112. It should be noted that when the sealing element 151 is installed in the first cavity 112, the first force-bearing surface 1111 and the second force-bearing surface 1112 are pressed to deform, so that the inner wall of the first cavity 112 is bent inward, and the inner wall of the first cavity 112 tightly fits the sealing element 151, thereby enhancing the sealing performance of the joint.

It should be noted that when the inner core 152 is stressed, the spring 153 is stressed to deform, so that the inner core 151 moves downward, and the inner core 151 is not blocking the first cavity 112.

In order to further improve the sealing of the joint. Further, the sealing assembly 15 further has at least one sealing ring 155, and the sealing ring 155 is used to enhance the sealing performance of the joint to prevent the joint from leaking. Further, the sealing ring 155 is mounted on the sealing member 151, and the sealing ring 155 is also mounted on the inner core 152.

Further, the joint is provided with a dust cap 16, and the dust cap 16 seals the opening 113 in a covering manner so as to prevent the sealing assembly 15 from being damaged.

Further, the joint is L-shaped. It is worth mentioning that when the pipeline is manually detected by the tool, if the joint is straightly installed on the pipeline, the detection tool manually used may not be used when encountering a narrow space. Therefore, when the joint is set to be L-shaped, the joint can be conveniently installed in a narrow space, and the joint is convenient for people to use tools for detection.

In summary, the joint based on the embodiment of the present application is clarified, which provides the joint with advantages of good sealing performance, low cost, convenient assembly and the like.

It is worth mentioning that in the embodiments of the present application, the joint structure is simple, does not involve complicated manufacturing processes and expensive materials, and has high economical efficiency.
