[0022] like Figure 1-6 As shown, a regulating valve for preventing accidental collision includes a valve body 1, in which a valve plate 3 is rotatably provided, and also includes a control mechanism 2, the upper end of the valve plate 3 is fixedly connected to a connecting shaft 301, the control mechanism 2 is connected to the connecting shaft 301, the control mechanism 2 includes a control disk 201, the control disk 201 is provided with a plurality of holding grooves 202, the lower end of the control disk 201 is fixedly connected to a connecting pipe 203, the valve body 1 is fixedly connected to a connecting seat 101, the connecting shaft 301 is rotatably extended out of the connecting seat 101, the connecting pipe 203 is movably connected in the connecting seat 101, the connecting shaft 301 is rotatably passed through the connecting pipe 203 and the control disk 201, and the control disk 201 is connected to a snap assembly 5 for limiting the connecting shaft 301.

[0023] like Figure 3 , 6 As shown, in order to limit the connecting shaft 301 and thereby rotate the control disk 201 to drive the connecting shaft 301 to rotate, the buckle assembly 5 includes a connecting member 501, the connecting member 501 is set to an elliptical ring shape, the connecting member 501 is slidably connected to the upper end of the control disk 201, the inner wall of the connecting member 501 is symmetrically fixed with a clamping block 502, the connecting shaft 301 is provided with a clamping groove 302, and the clamping block 502 is adapted to the clamping groove 302.

[0024] like Figure 5 As shown, in order to make the connecting member 501 slide stably on the control disk 201, the upper end of the control disk 201 is symmetrically provided with a limiting groove 206, and the lower end of the connecting member 501 is symmetrically fixed with a limiting member 505, and the limiting member 505 is slidably adapted in the limiting groove 206.

[0025] like Figure 6As shown, in order to stably fix the connecting member 501 when the block 502 is connected to the slot 302, the control panel 201 is symmetrically connected with a limit rod 503, and the limit rods 503 symmetrically contact the inner walls at both ends of the connecting member 501. The control panel 201 is provided with a mounting groove 207, and the lower end of the limit rod 503 is slidably adapted in the mounting groove 207. The mounting groove 207 is fixed with a first spring 504, and the lower end of the limit rod 503 is fixed to the first spring 504, and the upper end of the limit rod 503 extends out of the upper end of the control panel 201.

[0026] like Figure 4 , 5 As shown, in order to shrink the connecting shaft 301 into the control disk 201 and the connecting tube 203 when no adjustment is needed, a connecting groove 102 is provided in the connecting seat 101, and the connecting tube 203 is movably extended into the connecting groove 102. An annular stop plate 204 is fixedly connected to the lower end of the connecting tube 203, and the annular stop plate 204 is adapted to the connecting groove 102. An adjustment component 4 is provided in the connecting groove 102, and the adjustment component 4 includes a connecting ring 401 and a second spring 404. The connecting ring 401 is rotatably adapted to the upper end of the connecting groove 102. The connecting ring A limiting ring 402 is fixedly connected to the upper end of 401, and an annular limiting groove 103 is provided at the upper end of the connecting groove 102. The limiting ring 402 is rotatably adapted in the annular limiting groove 103, and the limiting ring 402 is rotatably sleeved on the connecting pipe 203. A plurality of sliding rods 403 are fixedly connected to the lower end of the limiting ring 402, and the second spring 404 is sleeved on the sliding rod 403. A plurality of through holes 205 are provided on the annular limiting plate 204, and the through holes 205 are slidably adapted to the sliding rod 403. The second spring 404 is arranged between the annular limiting plate 204 and the limiting ring 402.

[0027] When the utility model is in use and the valve disc 3 does not need to be adjusted, under the action of the adjusting assembly 4, the second spring 404 contracts naturally, driving the annular limit plate 204 to slide upward in the connecting groove 102, and at the same time, the sliding rod 403 slides into the through hole 205 to maintain the stability of the annular limit plate 204 sliding in the connecting groove 102, thereby causing the connecting shaft 301 to contract into the control disk 201 and the connecting pipe 203. At this time, the control disk 201 is accidentally touched or rotated to cause the connecting pipe 203 and the annular limit plate 204 to rotate in the connecting groove 102, and the limit ring 402 rotates in the annular limit groove 103, and the connecting shaft 301 remains stationary. When the valve disc 3 needs to be rotated, the control disk 201 is pressed to cause the annular limit plate 204 to squeeze the second spring 404, so that the connecting shaft 301 01 extends out of the upper end of the control disk 201, and the limiting rod 503 is pressed so that the limiting rod 503 squeezes the first spring 504 to shrink into the installation groove 207, thereby facilitating the sliding of the connecting member 501 on the control disk 201. The sliding of the connecting member 501 causes the block 502 on the connecting member 501 to slide into the groove 302 on the connecting shaft 301. At this time, under the action of the first spring 504, the limiting rod 503 extends out of the upper end of the control disk 201, and the mutually symmetrical limiting rods 503 abut against the two ends of the inner wall of the connecting member 501, thereby realizing the limiting fixation of the connecting member 501, and thereby making the block 502 keep the limiting position of the connecting shaft 301 in the groove 302. At this time, rotating the control disk 201 can drive the connecting shaft 301 to rotate and then drive the valve plate 3 to rotate, thereby realizing adjustment.

[0028] In summary: when used in the embodiment of the utility model, the control mechanism 2 is connected to the connecting shaft 301 and then the regulating valve plate 3 is rotated to adjust the flow of the valve body 1. When not in use, the block 502 in the buckle assembly 5 is separated from the slot 302 on the connecting shaft 301. Under the action of the adjusting assembly 4, the connecting shaft 301 is retracted to the control disk 201 and the connecting pipe 203. Rotating the control disk 201 will not cause linkage with the connecting shaft 301 and the valve plate 3, thereby effectively avoiding the linkage effect caused by accidental contact with the valve plate 3.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
