Detailed Embodiment

[0015] The present utility model will be further described in detail below with reference to the drawings.

[0016] Embodiment: A hemispherical angle cock with an elastic handle, as shown in Figure 1 and Figure 2As shown in the figure, it includes a cock body 1 and a handle body movably connected to the cock body 1. The handle body includes a rotating joint part 2 rotatably sleeved on the cock body 1 and a handle movable kit movably connected to the rotating joint part 2. By operating the handle body part, the user can realize the rotational adjustment of the rotating joint part 2 relative to the cock body 1, thereby realizing the opening and closing control of the cock body 1.

[0017] An ear groove block 3 is provided on the cock body 1, and a limit ear block 4 cooperating with the ear groove block 3 is provided on the rotating joint part 2. The free movement of the rotating joint part 2 relative to the cock body 1 can be restricted by the clamping of the limit ear block 4 and the ear groove block 3.

[0018] In order to further improve the safety and reliability of the handle part, the handle movable kit includes a handle block 5 movably connected to the rotating joint part 2 and an elastic auxiliary component provided between the handle block 5 and the rotating joint part 2. A rotating connection block 6 is provided at one end of the rotating joint part 2 away from the cock body 1. A rotating pin block 7 is provided on the rotating connection block 6. A rotating socket block 8 cooperating with the rotating connection block 6 is provided on the handle block 5. A rotating groove 9 cooperating with the rotating pin block 7 is provided on the rotating socket block 8. Relying on the relative rotation of the rotating pin block and the rotating groove 9, the stable rotation between the handle block 5 and the rotating joint part 2 can be realized.

[0019] A step protection groove 10 is provided at the notch of the rotating groove 9. An auxiliary pin block 11 cooperating with the step protection groove 10 is provided on the rotating pin block 7. A socket part 12 locked and fixed to the rotating pin block 7 is provided on the auxiliary pin block 11. When the handle block 5 rotates relative to the rotating connection block 6, the auxiliary pin block 11 works relative to the step protection groove 10. A plurality of telescopic return springs 13 are provided between the two sides of the auxiliary pin block 11 and the groove wall of the step protection groove 10. By using the elastic deformation process of the telescopic return springs 13, the rapid rebound reset of the handle block 5 after being accidentally squeezed or touched can be effectively realized.

[0020] When the user needs to rotate the rotating joint part 2 relative to the cock body 1 through the handle block 5, flexible switching control is realized by relying on the elastic auxiliary component, including a locking sleeve block 14 slidably sleeved on the rotating joint part 2 and elastic locking blocks 15 provided on both sides of the handle block 5. The flexible rotation limit control of the handle block 5 can be realized by the sliding of the locking sleeve block 14. A guiding chute 22 is provided on the side of the rotating joint part 2. A guiding slider 23 cooperating with the guiding chute 22 is provided on the locking sleeve block 14, ensuring the smoothness of the adjustment control of the locking sleeve. Wear-resistant blocks are provided on the inner wall of the locking sleeve block 14, which can meet the use reliability of repeated sliding.

[0021] That is, when the handle block 5 is aligned with the rotation joint 2, the sliding locking sleeve block 14 can complete the socketing of the handle block 5 to achieve locking. On both sides of the locking sleeve block 14, there are locking transverse grooves 16 for the elastic locking blocks 15 to slide and insert. At the end of the locking transverse groove 16 away from the handle block 5, there is a positioning circular groove 17. The elastic locking block 15 includes an elastic bottom block 18 fixed to the side of the handle block 5 and a locking ear block 19 elastically sleeved on the elastic bottom block 18. The locking ear block 19 includes an ear block one 20 and an ear block two 21. The diameter of the ear block one 20 is the same as the diameter of the positioning circular groove 17, and the diameter of the ear block two 21 is the same as the groove diameter of the locking transverse groove 16. As the locking sleeve block 14 slides and sockets, the operator needs to synchronously press the locking ear block 19, causing the elastic bottom block 18 to compress, so that the ear block two 21 slides along the locking transverse groove 16. When the locking ear block 19 reaches the part of the positioning circular groove 17, the pressing is withdrawn, and the ear block one 20 quickly pops out under the action of the elastic recovery potential energy of the elastic bottom block 18, and then completes the clamping with the positioning circular groove 17. There is a stepped protection ring edge 26 on the ear block one 20, which can improve the smoothness of the locking and locking of the locking ear block 19.

[0022] Since the diameter of the ear block one 20 is larger than that of the ear block two 21, the final cooperation between the locking ear block 19 and the positioning circular groove 17 can fix the position of the locking sleeve block 14 relative to the handle block 5, restrict the rotation of the handle block 5 relative to the rotation joint 2, and finally achieve the structural consistency of the operator holding the handle block 5 to apply force to adjust the position state of the rotation joint 2.

[0023] In order to improve the reliability and convenience in the actual use process, there is a corrugated block 24 at one end of the handle block 5 away from the rotation joint 2, and a pressing groove block 25 is provided on the surface of the locking sleeve block 14, which is convenient for the operator to hold the corrugated block 24 part of the handle block 5 with one hand. There is also a pressing block 27 at the end of the locking ear block 19. When the operator holds the handle block 5, pressing the pressing block 27 with the thumb synchronously can quickly achieve the relative sliding of the locking sleeve. The pressing groove block 25 further improves the reliability and convenience of the operator during the operation of the handle block 5, and fully guarantees the convenience of the single-person and single-hand operation scenario.

[0024] When the control operation of the handle block 5 on the rotation joint 2 is completed, the operator successively completes the limit contact of the locking sleeve block 14 relative to the handle block 5, presses the pressing block 27, and slides the locking sleeve block 14 away from the handle block 5 until the ear block two 21 slides out of the locking transverse groove 16. At this time, the entire handle block 5 is in the mis-touch protection state. Once the handle block 5 is driven to rotate due to external mis-pressing, relying on the cooperation of the rotating connection block 6 and the rotating socket block 8 can quickly achieve buffer protection. Only the rotation of the handle block 5 can be realized, and the driving adjustment of the rotation joint 2 cannot be realized. Moreover, the handle block 5 can quickly reset after the external force is withdrawn, forming the mis-touch safety protection effect of the handle block 5 and improving the reliable performance of the entire plug door handle.

[0025] This specific embodiment is only an interpretation of the present utility model, and it does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
