[0024] like Figures 1 to 4 As shown, an elbow includes a main body 2 and several connectors 3, the main body 2 has a circulation channel 21, and the main body 2 is provided with two connecting structures 22 at both ends of the circulation channel 21, the connecting structure 22 includes a connecting groove 221 arranged on the main body 2, the connecting groove 221 is arranged around the circulation channel 21 and is connected to the circulation channel 21, and the side wall of the connecting groove 221 away from the circulation channel 21 is provided with a limiting groove 222, and the limiting groove 222 is arranged around the circulation channel 21; a guide groove 223 for connecting the outside world and the limiting groove 222 is provided on the main body 2, and each connecting structure 22 can correspond to a detachable connection of a connector 3; the connector 3 has a limiting block 31, and the limiting block 31 can enter from the guide groove 223 and be stuck in the limiting groove 222 to limit the connector 3 from falling out.

[0025] In this application, the main body 2 is provided with a circulation channel 21 for conveying fluids, etc., and connecting structures 22 are set at its two ends. The connecting groove 221 in the connecting structure 22 surrounds the circulation channel 21 and is connected to it, which provides basic space for the installation of the connector 3. The limiting groove 222 opened on the side wall of the connecting groove 221 surrounds the circulation channel 21. At the same time, the main body 2 has a guide groove 223 connecting the outside world and the limiting groove 222. When installing the connector 3, the connector 3 is aligned with the connecting groove 221, so that the limiting block 31 of the connector 3 enters along the path of the guide groove 223, and then rotated and clamped in the limiting groove 222. Through the cooperation of the limiting block 31 and the limiting groove 222, the limiting of the connector 3 on the connecting structure 22 is achieved, so that the connector 3 is firmly installed at both ends of the main body 2, completing the assembly of the entire elbow and the connector 3, so that it can be put into normal use in the corresponding pipeline connection work.

[0026] The sizes of the several connectors 3 in this application are different, but the ends of all connectors 3 corresponding to the connecting structure 22 are consistent. Several connectors 3 of different sizes are configured. According to the different specifications of the actual connected pipes, the connector 3 of the appropriate size can be selected to connect to the main body 2, avoiding the limitation of traditional elbow connectors that can only match pipes of specific specifications due to the fixed interface size at both ends, and improving the versatility of the elbow in different pipe connection scenarios.

[0027] Furthermore, the flow channel is non-linear. The two central axes of the two connecting structures 22 on the main body are perpendicular to each other.

[0028] Specifically, when the limiting block 31 is in the limiting groove 222 , the limiting block 31 can abut against the bottom wall 2211 of the connecting groove 221 .

[0029] The limiting block 31 is located in the limiting groove 222 and can abut against the bottom wall 2211 of the connecting groove 221, limiting the connector 3 from multiple directions. Furthermore, one end wall of the connector 3 also abuts against the bottom wall 2211 of the connecting groove 221.

[0030] Specifically, a sliding groove 32 corresponding to the guide groove 223 is formed on the connector 3 , and a slider 33 is slidably provided in the sliding groove 32 . The slider 33 can enter the guide groove 223 to limit the rotation of the connector 3 .

[0031] When installing the connecting head 3 to the connecting structure 22 of the main body 2, the connecting head 3 must first be aligned with the connecting groove 221 on the main body 2, and the connecting head 3 must be moved toward the connecting groove 221 until the limit block 31 completely enters the limit groove 222. At this time, the connecting head 3 is started to be rotated until the slider 33 on the connecting head 3 is aligned with the guide groove 223, and the slider 33 is sent into the guide groove 223, thereby limiting the rotation of the connecting head 3.

[0032] Specifically, an elastic piece 34 is provided between the slider 33 and the inner wall of the sliding groove 32 , and the elastic piece 34 enables the slider 33 to move toward the connecting groove 221 .

[0033] In the initial state, since the elastic piece 34 is provided between the slider 33 and the inner wall of the sliding groove 32 , the elastic piece 34 exerts an elastic force on the slider 33 , causing the slider 33 to have a tendency to move toward the connecting groove 221 .

[0034] When the connector 3 is inserted into the connecting groove 221, the slider 33 is squeezed, causing the elastic sheet 34 to be compressed. During the rotation of the connector 3, when the slider 33 moves to the position corresponding to the guide groove 223, the slider 33 automatically falls into the guide groove 223 through the elastic sheet 34, thereby limiting the rotation of the connector 3.

[0035] Specifically, two ends of the elastic piece 34 are respectively welded to the inner wall of the sliding groove 32 and the sliding block 33 .

[0036] The two ends of the elastic sheet 34 are connected to the inner wall of the slide groove 32 and the slider 33 respectively by welding, so that a firm and stable connection structure 22 is formed between the elastic sheet 34 and the two. During long-term use, even in the face of frequent external forces, vibrations and other complex working conditions, the elastic sheet 34 is not prone to loosening, falling off or displacement.

[0037] Specifically, a receiving groove is formed on the bottom wall 2211 of the connecting groove 221 , and a sealing ring 4 is installed in the receiving groove.

[0038] A receiving groove is opened on the bottom wall 2211 of the connecting groove 221 and a sealing ring 4 is installed. When the connecting head 3 is connected to the main body 2, the connecting head 3 will fit tightly with the bottom wall 2211 of the connecting groove 221. At this time, the sealing ring 4 is located between the two and is squeezed and deformed, thereby filling the tiny gap that may exist between the connecting head 3 and the bottom wall 2211 of the connecting groove 221, effectively preventing the fluid from leaking from the connection part when flowing through the elbow.

[0039] Specifically, there are at least two guide grooves 223 , which are circumferentially arranged around the circulation channel 21 .

[0040] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although this specification has described the present application in detail with reference to the above embodiments, ordinary technicians in this field should understand that technicians in the relevant technical field can still modify or replace the present application with equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
