Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 4, an embodiment provided by the present utility model: an adjustable fully welded ball valve with anti-theft function, comprising a valve body 1, the valve body 1 being the main body of the fully welded ball valve. A valve top 3 is fixedly connected to the top of the valve body 1. A valve core connecting rod 2 is rotatably connected inside the valve body 1. A turning handle 4 is slidably connected inside the valve top 3. The valve core connecting rod 2 is used to connect the ball valve core inside the valve body 1 and can adjust the flow rate inside the ball valve. A connecting rod 6 is slidably connected to the middle of the turning handle 4. A cross bar 8 is fixedly connected to the bottom of the connecting rod 6. A spring 7 is fixedly connected to the top of the cross bar 8. The connecting rod 6 is used to connect the cross bar 8 and can drive the cross bar 8 to move when the connecting rod 6 moves, while the spring 7 is used to provide elastic support. Rotating rods 9 are rotatably connected to both the front and rear ends of the cross bar 8. Connecting blocks 10 are rotatably connected to the ends of the two rotating rods 9 away from the cross bar 8. The rotating rods 9 are used to connect the cross bar 8 and the connecting blocks 10. Plug blocks 11 are fixedly connected to the bottoms of the two connecting blocks 10. A limiting rod 12 is fixedly connected to the bottom side inside the turning handle 4. The inner parts of the two plug blocks 11 are respectively slidably connected to the front and rear sides of the limiting rod 12. The connecting blocks 10 are fixedly connected to the plug blocks 11, and the plug blocks 11 slide on the outer periphery of the limiting rod 12. The movement of the plug blocks 11 can be restricted by the limiting rod 12. A dial rod 5 is fixedly connected to the top of the connecting rod 6. The dial rod 5 is slidably connected inside the turning handle 4. The outer peripheries of the separated ends of the two plug blocks 11 are respectively slidably connected to the front and rear sides inside the valve core connecting rod 2. The dial rod 5 is used to drive the connecting rod 6 to move, and by inserting the two plug blocks 11 into the inside of the valve core connecting rod 2, the turning handle 4 can be connected to the valve core connecting rod 2.

[0034] Refer to Figure 1 , Figure 2 , Figure 5 , a protection component is provided on the outer periphery of the valve body 1. The protection component is used to protect the valve body 1. The protection component includes a protection box 13. The protection box 13 is slidably connected to the outer periphery of the valve body 1 and is used to protect the internal valve body 1 from external damage. A mounting plate 14 is slidably connected to the bottom of the protection box 13. Mounting rods 15 are fixedly connected to both the front and rear sides of the bottom of the protection box 13. The two mounting rods 15 are respectively slidably connected to the front and rear sides inside the mounting plate 14. The mounting plate 14 is used to fix the position of the protection box 13.

[0035] Refer to Figure 5, fixing components are provided on both the front and rear sides inside the mounting plate 14. The fixing components are used to fix the mounting plate 14 and the protection box 13. The fixing components include insertion rods 16. The insertion rods 16 are slidably connected inside the mounting plate 14. A limiting plate 17 is fixedly connected to the outer periphery of the insertion rod 16. A compression spring 18 is fixedly connected to one side of the limiting plate 17. The compression spring 18 is sleeved on the outer periphery of the insertion rod 16. The insertion rod 16 is fixedly connected to the limiting plate 17. When the insertion rod 16 moves, it can drive the limiting plate 17 to move together. Furthermore, when the limiting plate 17 moves, it can apply pressure to the compression spring 18. One end of the insertion rod 16 is fixedly connected to a pulling block 19. The end of the insertion rod 16 far from the pulling block 19 is slidably connected inside the mounting rod 15. By inserting the insertion rod 16 into the inside of the mounting rod 15, the mounting rod 15 can be limited, so that the protection box 13 is connected to the mounting plate 14. And when the insertion rod 16 slides out of the mounting rod 15, the mounting rod 15 can be taken out of the mounting plate 14, thereby separating the protection box 13 from the mounting plate 14.

[0036] Working principle: When in use, first place the valve body 1 in the middle of the mounting plate 14, and then pull the pulling block 19. The pulling block 19 drives the insertion rod 16 to move. When the insertion rod 16 moves, it can drive the limiting plate 17 to move together. And the limiting plate 17 can squeeze the compression spring 18 during the moving process. Then insert the two mounting rods 15 at the bottom of the protection box 13 into the front and rear sides inside the mounting plate 14. After the two mounting rods 15 enter the inside of the mounting plate 14, release the pulling block 19. The compression spring 18 loses pressure and then resets and will generate a thrust on the limiting plate 17. And when the limiting plate 17 receives the thrust, it will drive the insertion rod 16 to move, so that the insertion rod 16 is inserted into the inside of the mounting rod 15 to limit the mounting rod 15. At this time, the mounting plate 14 and the protection box 13 will complete the connection.

[0037] Secondly, when the ball valve needs to be adjusted, lift the lever 5 inside the turning handle 4 upward. When the lever 5 moves, it will drive the connecting rod 6 to move together. And the cross bar 8 fixed to the bottom of the connecting rod 6 will move together with the connecting rod 6. Furthermore, the cross bar 8 moves upward. When the cross bar 8 moves upward, it will apply a squeezing force to the spring 7. The two rotating rods 9 at the front and rear ends of the cross bar 8 will rotate relatively. When the two rotating rods 9 rotate relatively, the two connecting blocks 10 will drive the two insertion blocks 11 to move along the limiting rod 12 together. At this time, the two insertion blocks 11 move toward each other and slide into the inside of the turning handle 4. Then insert the bottom of the turning handle 4 into the inside of the valve top 3, and insert the middle of the turning handle 4 into the inside of the valve core connecting rod 2. Then release the lever 5. The spring 7 loses the squeezing force and then generates a reset, pushing the cross bar 8 to move downward. When the cross bar 8 moves downward, the two rotating rods 9 will rotate in the opposite direction. And at this time, the two connecting blocks 10 will drive the two insertion blocks 11 to move along the limiting rod 12 in the opposite direction. After the two insertion blocks 11 slide into the inside of the valve core connecting rod 2, the turning handle 4 and the valve core connecting rod 2 will complete the connection, so that the adjustment can be carried out.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
