[0003] When the existing Y-shaped tee is in use, it is not convenient to limit the joint, so that the joint is prone to accidental rotation, and then it is easy to fall off after being threadedly connected to the external pipeline. This phenomenon has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-pressure resistant and deformation resistant Y-shaped tee with a limiting structure for the existing device, so as to solve the problems put forward in the above background technique.

[0005] In order to solve the above technical problems, the utility model provides the following technical solution: A high-pressure resistant and deformation resistant Y-shaped tee with a limiting structure, including a tee body. Sealing gaskets are fixedly connected to both the inlet and outlet of the tee body. Connectors are threadedly connected to both the inlet and outlet of the tee body. A fixed convex block is fixedly connected to the outer wall of the connector. A support block is fixedly connected to the outer wall of the tee body. A fixed shaft is fixedly connected to the inner wall of the support block. A scroll spring is fixedly connected to the outer wall of the fixed shaft. A movable rod is fixedly connected to the outer wall of the scroll spring. By providing the tee body, the sealing gasket, the connector, the fixed convex block, the support block, the fixed shaft, the scroll spring and the movable rod, the limiting function is realized, thus solving the problem of loosening and falling off caused by accidental rotation of the connector, and further improving the firmness of the connection, meeting the working needs of people, and being worthy of popularization and use.

[0006] Furthermore, the sealing gasket is of an elastic structure and is in mutual contact with the inner wall of the connector, which is beneficial to improving the sealing effect and preventing the connector from falling off from the tee body.

[0007] Furthermore, a number of fixed convex blocks are equiangularly distributed on the outer wall of the connector, which facilitates the subsequent limiting work.

[0008] Furthermore, the support block is of a "concave" shape structure, and the movable rod is rotatably connected to the support block through the fixed shaft, which facilitates the support of the movable rod.

[0009] Furthermore, the top view of the movable rod is an "L" - shaped structure, and the movable rod forms a rotating structure with the fixed shaft through a scroll spring, which facilitates driving the movable rod to rotate back to its original position.

[0010] Furthermore, the length of the movable rod is greater than the length of the connecting head, and the width of the movable rod is less than the spacing between the fixed bumps, which facilitates the limiting work of the connecting head by the movable rod and prevents the accidental rotation of the connecting head.

[0011] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0012] (1) By providing a tee body, a gasket, a connecting head, fixed bumps, a support block, a fixed shaft, a scroll spring and a movable rod, the function of limiting is realized, thus solving the problem of loosening and falling off caused by the accidental rotation of the connecting head, further improving the firmness of the connection, meeting the working needs of people, and being worthy of popularization and use.

[0018] The following further describes the technical solution of the present utility model in detail in conjunction with the preferred embodiments and their drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-3The utility model provides a technical solution: a high-pressure resistant and deformation-resistant Y-type tee with a limiting structure, comprising a tee body 1, a sealing gasket 2 is fixedly connected at the inlet and outlet of the tee body 1, a connector 3 is threadedly connected at the inlet and outlet of the tee body 1, the outer wall of the connector 3 is fixedly connected with a fixing protrusion 4, the outer wall of the tee body 1 is fixedly connected with a supporting block 5, the inner wall of the supporting block 5 is fixedly connected with a fixing shaft 6, the outer wall of the fixing shaft 6 is fixedly connected with a volute spring 7, and the outer wall of the volute spring 7 is fixedly connected with a movable rod 8. By arranging the tee body 1, the sealing gasket 2, the connector 3, the fixing protrusion 4, the supporting block 5, the fixing shaft 6, the volute spring 7 and the movable rod 8, the limiting function is realized, thereby solving the problem of loosening and falling off caused by accidental rotation of the connector 3, thereby improving the firmness of the connection, meeting people's work needs, and worthy of popularization and use.

[0020] Furthermore, the sealing gasket 2 is an elastic structure, and the sealing gasket 2 and the inner wall of the connector 3 abut against each other, which is beneficial to improving the sealing effect and preventing the connector 3 and the tee body 1 from falling off.

[0021] Furthermore, a plurality of fixing protrusions 4 are distributed at equal angles on the outer wall of the connector 3 , which facilitates subsequent limiting work.

[0022] Furthermore, the support block 5 is a "concave"-shaped structure, and the movable rod 8 is rotatably connected to the support block 5 via the fixed shaft 6, which facilitates the support of the movable rod 8.

[0023] Furthermore, the movable rod 8 is an "L"-shaped structure when viewed from above, and the movable rod 8 forms a rotating structure with the fixed shaft 6 through the spiral spring 7, which facilitates the movable rod 8 to be driven to return and rotate.

[0024] Furthermore, the length of the movable rod 8 is greater than the length of the connector 3, and the width of the movable rod 8 is less than the spacing between the fixed protrusions 4, which facilitates the limiting work of the connector 3 by the movable rod 8 to prevent the connector 3 from rotating accidentally.

[0025] When in use, first move the movable rod 8 to rotate, so that the movable rod 8 drives the volute spring 7 to deform, so that the movable rod 8 slides out of the gap between the fixed protrusions 4, and then the connecting head 3 can be rotated to connect with the threaded joint of the external pipe. After the connection is completed, release the movable rod 8, so that the volute spring 7 drives the movable rod 8 to reset and rotate, and then slides into the gap between the fixed protrusions 4, thereby limiting the fixed protrusions 4, so that the connecting head 3 will not rotate accidentally, thereby improving the firmness after connection.
