Detailed implementation manners

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , where Figure 1 is the overall structural view of a pneumatic power machine provided with an adjusting mechanism according to the present utility model; Figure 2 is the schematic side sectional view of a pneumatic power machine provided with an adjusting mechanism according to the present utility model; Figure 3 is Figure 2 an enlarged structural view of part A in Figure 4 is the schematic view of the unlocking state structure of the rotating rod of a pneumatic power machine provided with an adjusting mechanism according to the present utility model. The pneumatic power machine provided with an adjusting mechanism includes: a pressure switch 1, a pressure regulating screw 101 is threadedly installed on the pressure switch 1, and a buckle mechanism is arranged on the pressure regulating screw 101;

[0023] The snap mechanism includes a rotating rod 2, the bottom end of the rotating rod 2 extends into the pressure regulating screw 101 and is movably connected to the pressure regulating screw 101. An annular baffle 201 is fixedly installed at the bottom end of the rotating rod 2. Two fixing blocks 3 are fixed to the inner wall of the rotating rod 2, and the two fixing blocks 3 are symmetrically distributed. An installation groove 301 is formed inside the fixing block 3. A ejector rod 302 is slidably connected inside the installation groove 301. A top block 303 is fixedly installed at one end of the ejector rod 302. A first spring 304 is fixedly connected to the inner wall of the installation groove 301, and one end of the first spring 304 is fixedly connected to the ejector rod 302. A bottom rod 4 is fixedly installed inside the pressure regulating screw 101. A fixing rod 401 is fixedly connected to the top end of the bottom rod 4. A first stop block 402 is fixedly installed at the top end of the fixing rod 401. A second stop block 403 is slidably sleeved on the fixing rod 401.

[0024] As Figure 2 and Figure 4 shown, two groups of limiting blocks 202 are fixedly installed on the rotating rod 2, and the two groups of limiting blocks 202 are symmetrically distributed. Two groups of guiding grooves are formed on the inner wall of the pressure regulating screw 101, and the limiting blocks 202 are adapted to the guiding grooves;

[0025] By providing the guiding grooves, the limiting blocks 202 can be in the guiding grooves to limit the rotating rod 2, facilitating the rotating rod 2 to drive the pressure switch 1 to rotate.

[0026] As Figure 3 shown, a guiding rod 305 is fixedly connected to the top block 303, and one end of the guiding rod 305 extends into the fixing block 3 and is slidably connected to the fixing block 3;

[0027] By providing the guiding rod 305, the top block 303 can move smoothly when being extruded and telescoped and moving in parallel.

[0028] As Figure 2 shown, a second spring 5 is fixedly installed inside the pressure regulating screw 101. The second spring 5 is adapted to the inside of the pressure regulating screw 101, and the top end of the second spring 5 abuts against the annular baffle 201.

[0029] By providing the second spring 5, after the rotating rod 2 is released from the limit, the second spring 5 can push the rotating rod 2 to move outwards of the pressure regulating screw 101, and then it is convenient to twist the rotating rod 2 to drive the pressure regulating screw 101 when rotating.

[0030] As Figure 3 shown, inclined surface structures are formed on both groups of top blocks 303, and the two groups of inclined surface structures are symmetrically distributed;

[0031] By providing the inclined surface structures on the top blocks 303, it is convenient to reduce the friction force when the inclined surfaces of the top blocks 303 are in limit contact with the first stop block 402.

[0032] As Figure 1 shown, a plurality of radial grooves are formed on the surface of the rotating rod 2, and the plurality of radial grooves are distributed around the rotating rod 2;

[0033] By providing the radial grooves, it is convenient to increase the friction when the rotating rod 2 is rotated by hand, thereby improving the rotational convenience.

[0034] The working principle of the pneumatic power machine provided with the adjusting mechanism of the present utility model is as follows:

[0035] First step: By pressing the rotating rod 2, the rotating rod 2 drives the top block 303 to move vertically downward. Then, when the two top blocks 303 move to the first stop block 402, they will be pushed open and move towards the fixed block 3. Then, when the top block 303 completely moves to the bottom of the first stop block 402, the elastic force of the first spring 304 will push the ejector rod 302 to move, and then the ejector rod 302 pushes the top block 303 to move to the bottom of the first stop block 402, so that the rotating rod 2 is limited, and then the rotating rod 2 is retracted into the pressure regulating screw 101;

[0036] Second step: After the top block 303 is limited to the bottom of the first stop block 402, the rotating rod 2 can be pressed vertically downward again, so that the rotating rod 2 drives the two top blocks 303 to move away from the top of the second stop block 403 in a staggered manner and enter the bottom of the second stop block 403. Then, the two top blocks 303 are pressed against the bottom of the second stop block 403 under the action of the elastic force of the first spring 304. At this time, the reset of the second spring 5 will push the annular baffle 201 to drive the rotating rod 2 to move upward. At the same time, the two top blocks 303 drive the second stop block 403 to move to the bottom of the first stop block 402. After the top of the second stop block 403 is merged with the top of the first stop block 402, the two top blocks 303 can move upward between the first stop block 402 and the second stop block 403, and finally move above the first stop block 402 to release the limit on the rotating rod 2. After the rotating rod 2 extends from the top of the pressure regulating screw 101, it is convenient to twist the rotating rod 2 to drive the pressure regulating screw 101 to rotate to adjust the pressure, with convenient operation and high efficiency.
