[0002] An angle cock is a control valve for connecting and disconnecting the air circuits between railway locomotives, between locomotives and vehicles, and between vehicles. After its handle is lifted, it can be rotated by 90° to realize the opening and closing of the air circuit. When this type of angle cock handle is in a non-rotating use state, it is mainly limited by the block on the handle and the rotating stop on the valve body to limit the rotation of the handle to maintain the working state of the angle cock. However, with long-term use, especially when applied in the railway locomotive system, the handle and the valve body are prone to move, resulting in the accidental lifting of the handle, which brings about the release of the limit between the block on the handle and the rotating stop, posing a hidden danger to maintaining the stable working state of the angle cock. Content of the Utility Model

A rotating block is provided on the side of the installation rotating groove away from the rotating connection groove block. A rotating stop block cooperating with the rotating block is provided on the angle cock body. A pair of movable locking blocks are also slidably connected to both sides of the rotating block. An installation sliding groove is provided on the locking block. An installation sliding block slidably connected to the installation sliding groove is provided on the rotating block. A reset sliding groove block is also provided on the locking block. A sliding ear block slidably cooperating with the reset sliding groove block is provided on the rotating block. A reset compression spring is inserted between the sliding ear block and the groove wall of the reset sliding groove block. A pressing ring edge is also provided on the side wall of the valve core block between the locking blocks.
[0005] Further: A locking edge is provided at one end of the locking block in contact with the rotating stop block. An auxiliary pressing groove for the rotating block to be fitted and inserted is provided on the locking edge.
[0006] Further: A guiding bevel edge is provided on the rotating stop block.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0018] Embodiment: A handle of a hemispherical corner plug door, such as Figure 1 and Figure 2 As shown, it includes an angled plug gate body 1, a valve core block 2 rotatably plugged with the angled plug gate body 1, and a handle block 3 rotatably connected with the valve core block 2. The valve core block 2 on the angled plug gate body 1 can be controlled by the operation of the handle block 3.
[0019] The handle block 3 includes a handle rotating part 4 and a handle grip part 5. The operator holds the handle grip part 5 to drive the handle rotating part 4 to rotate and adjust. The handle rotating part 4 is provided with an installation rotating groove 6, which can realize the movable socket connection with the top end of the valve core block 2 during the process of lifting and releasing the handle. On the side of the installation rotating groove 6 away from the handle grip part 5, there is a rotating connection groove block 7 rotatably connected to the valve core block 2, ensuring the rotation of the handle block 3 relative to the valve core block 2 for torsion adjustment.
[0020] On the side of the installation rotating groove 6 away from the rotating connection groove block 7, there is a rotating clamping block 8. On the angle cock body 1, there is a rotating stop block 9 cooperating with the rotating clamping block 8. The cooperation between the rotating stop block 9 and the rotating clamping block 8 can be realized, thereby improving the stability of the handle block 3 in the locked and closed state.
[0021] As Figure 1 、 Figure 3 and Figure 4 shown, in order to further improve the locking stability of the handle block 3, a pair of movable locking blocks 10 are also slidably connected to both sides of the rotating clamping block 8, which are used to improve the intensity of the cooperation and clamping between the rotating clamping block 8 and the rotating stop block 9. The locking block 10 is provided with an installation sliding groove 11, and the rotating clamping block 8 is provided with an installation sliding block 12 slidably connected to the installation sliding groove 11, restricting the rotation and sliding path of the locking block 10 relative to the rotating clamping block 8 and reducing the sliding displacement deviation. On the locking block 10, there is also a reset sliding groove block 13, and the rotating clamping block 8 is provided with a sliding ear block 14 slidably matched with the reset sliding groove block 13. A reset compression spring 15 is arranged between the sliding ear block 14 and the groove wall of the reset sliding groove block 13. The sliding of the sliding ear block 14 relative to the reset sliding groove block 13 is realized by the elastic expansion and contraction of the reset compression spring 15. Both the sliding ear block 14 and the reset sliding groove block 13 are provided with abutting convex blocks 22 for the end of the reset compression spring 15 to be clamped, which helps to improve the deformation reliability of the reset compression spring 15 during the expansion and contraction process. Finally, when the operator presses the handle block 3, the extrusion of the locking block 10 relative to the rotating stop block 9 is realized, so as to drive the locking block 10 to slide relative to the rotating clamping block 8 and compress the reset compression spring 15, achieving the abutting between the locking block 10 and the rotating stop block 9 and ensuring the stability of the handle block 3 in the locked state.
[0022] In order to further improve the reliable cooperation between the locking block 10 and the rotating block 8, a locking edge 17 is provided at one end of the locking block 10 in contact with the rotating stop block 9, and an auxiliary pressing groove 18 for the rotating block 8 to be fitted and inserted is provided on the locking edge 17. That is, when the handle block 3 is pressed by the operator to complete the locking with the angle cock body 1, the auxiliary pressing groove 18 is clamped with the rotating block 8, improving the limit sliding and cooperative locking effect between the rotating block 8 and the locking block 10. Considering the smoothness of the contact movement between the locking block 10 and the rotating stop block 9 during the pressing and buckling process of the handle block 3, a guiding bevel edge 19 is provided on the rotating stop block 9. The relative sliding of the guiding bevel edge 19 and the locking block 10 helps to limit and guide the pressing movement of the handle block 3, ensuring a smooth process of the relative extrusion between the locking block 10 and the rotating stop block 9 to the abutting state. A friction convex rib block 23 is provided at the end of the locking block 10, further improving the fullness of the pressing and locking between the locking block 10 and the rotating stop block 9 and reducing the state of the handle block 3 being freely opened.
[0023] Since during the pressing and lifting process of the handle block 3, a pair of locking blocks 10 maintain relative sliding with the rotating block 8, a pressing ring edge 16 is further provided on the side wall of the valve core block 2 located between the locking blocks 10. An elastic pressing block 21 is provided on the side of the locking block 10 in contact with the pressing ring edge 16. When the operator presses the handle block 3 to complete the locking, the locking block 10 can maintain extrusion with the rotating stop block 9, and at the same time, the locking block 10 rotates relative to the rotating block 8, realizing the pressing of the end away from the rotating stop block 9 against the pressing ring edge 16, further improving the locking effect between the handle block 3 and the angle cock body 1.
[0024] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
