Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1: As Figures 1-8 As shown, the technical solution adopted by this utility model is as follows: A regulating assembly for a pneumatic joint regulating valve includes a valve body 1, and a valve core 2 is fixedly disposed inside the valve body 1. The valve core 2 is horizontally arranged and fixedly penetrates the valve body 1.

[0040] A connecting sleeve 6 is fixedly connected to one end of the valve core 2. A portion of the connecting sleeve 6 extends to the outside of the valve core 2.

[0041] The valve body 1 has an air outlet 4 at its top, and the valve core 2 has an air inlet 5 at its end away from the connecting sleeve 6. Several vent holes 3 are formed in the middle of the valve core 2, arranged in a circular array around the valve core 2. All vent holes 3 are located directly below the air outlet 4 and communicate with the inner cavity of the valve body 1. There is a gap between the outer surface of the valve core 2 where the vent holes 3 are located and the inner wall of the valve body 1, allowing communication between the inner cavity of the valve body 1 and the inner cavity of the valve core 2 through the vent holes 3.

[0042] An adjusting rod 8 is connected to the internal thread of the connecting sleeve 6. The inner wall of the connecting sleeve 6 has an internal thread, and the outer surface of the adjusting rod 8 has an external thread that matches the internal thread. The adjusting rod 8 is positioned within the connecting sleeve 6 by the engagement of the internal and external threads, sealing the end of the valve core 2 and ensuring that gas entering the valve core 2 can only be discharged through the vent hole 3.

[0043] One end of the adjusting rod 8 extends into the valve core 2. The other end of the adjusting rod 8 can also extend into the air inlet 5.

[0044] The adjusting rod 8 has an annular mounting groove 9 at one end that extends into the valve core 2, and an annular sealing ring 10 is fixedly installed inside the mounting groove 9. The sealing ring 10 is made of rubber and moves against the inner wall of the air inlet 5. When the end of the adjusting rod 8 moves the sealing ring 10 into the air inlet 5, the inner wall of the air inlet 5 will squeeze the sealing ring 10, so that the sealing ring 10 completely seals the end of the air inlet 5, and the gas in the air inlet 5 cannot be discharged.

[0045] One end of the adjusting rod 8 that extends into the valve core 2 is truncated cone-shaped. This causes the gas passage between the outer surface of the adjusting rod 8 and the inner wall of the air inlet 5 to gradually decrease as the adjusting rod 8 extends into the air inlet 5, thus slowing down the gas flow rate.

[0046] A nut 7 is fixedly connected to the other end of the adjusting rod 8. When the nut 7 rotates, it will cause the adjusting rod 8 to rotate inside the connecting sleeve 6, thereby changing the length of the adjusting rod 8 extending into the valve core 2.

[0047] The end of the button 7 near the connecting sleeve 6 is connected to the limiting sleeve 11 via a spring 12. The limiting sleeve 11 is fitted onto the adjusting rod 8.

[0048] An annular retaining ring 17 is fixedly connected inside the limiting sleeve 11, and the adjusting rod 8 passes through the retaining ring 17. One end of the spring 12 is fixedly connected to one side of the retaining ring 17, and the other end of the spring 12 is fixedly connected to the inner wall of the button 7. In the initial state, the spring 12 pushes the retaining ring 17 to move away from the button 7.

[0049] One end of the limiting sleeve 11 is fitted onto the button 7, and the other end of the limiting sleeve 11 can be fitted onto the connecting sleeve 6.

[0050] A first connecting portion 13 is fixedly provided on the outer surface of the button cap 7. A first snap-fit ​​portion 14 is fixedly provided on the inner wall of one end of the limiting sleeve 11, and the first snap-fit ​​portion 14 is movably snapped onto the first connecting portion 13. The limiting sleeve 11 is positioned on the button cap 7 by the cooperation between the first snap-fit ​​portion 14 and the first connecting portion 13, so that the rotation of the limiting sleeve 11 will drive the button cap 7 to rotate.

[0051] A second connecting portion 15 is fixedly provided on the outer surface of one end of the connecting sleeve 6. A second snap-fit ​​portion 16 is fixedly provided on the inner wall of the other end of the limiting sleeve 11, and the second snap-fit ​​portion 16 is movably snapped onto the second connecting portion 15. The limiting sleeve 11 is positioned on the connecting sleeve 6 by the cooperation of the second snap-fit ​​portion 16 and the second connecting portion 15, thereby positioning the button 7.

[0052] The first connecting part 13 is composed of several straight first protrusions, which are uniformly fixed to the outer surface of the button cap 7. The surface of the first protrusion is arc-shaped, and an arc-shaped first groove is formed between two adjacent first protrusions on the outer surface of the button cap 7.

[0053] The first engaging portion 14 is composed of several straight first toothed posts, which are uniformly fixed to the inner wall of the limiting sleeve 11. The first toothed posts slide and engage inside the first grooves. The number of first toothed posts is less than the number of first grooves, that is, when the first engaging portion 14 is engaged with the first connecting portion 13, there can be multiple first grooves spaced apart between two first toothed posts.

[0054] The connection points between each first protrusion and the outer surface of the button 7 are formed by two straight lines, and the two straight lines on each first protrusion are parallel to each other, so that the two sides of each first groove are also straight lines. The shape of the first tooth post is adapted to the shape of the first groove.

[0055] The second connecting part 15 consists of several straight second protrusions, which are uniformly and fixedly connected to the outer surface of the connecting sleeve 6. The surface of the second protrusion is arc-shaped, and an arc-shaped second groove is formed between two adjacent second protrusions on the outer surface of the connecting sleeve 6.

[0056] The second engaging portion 16 consists of several straight second toothed posts, which are uniformly and fixedly connected to the inner wall of the limiting sleeve 11. The second toothed posts slide and engage inside the second grooves. The number of second toothed posts is less than the number of second grooves, that is, when the second engaging portion 16 is engaged with the second connecting portion 15, there can be multiple second grooves spaced apart between two second toothed posts.

[0057] The connection points between each second protrusion and the outer surface of the connecting sleeve 6 are formed by two straight lines, and the two straight lines on each second protrusion are parallel to each other, so that the two sides of each second groove are also straight lines. The shape of the second toothed post is adapted to the shape of the second groove.

[0058] Working principle:

[0059] When in use, gas enters the valve core 2 through the air inlet 5, then enters the valve body 1 through the vent 3, and finally exits through the air outlet 4.

[0060] When the gas flow rate needs to be adjusted, pull the limiting sleeve 11 away from the connecting sleeve 6, so that the second locking part 16 disengages from the second connecting part 15, that is, the second toothed post disengages from the second groove. At the same time, the limiting sleeve 11 drives the retaining ring 17 to move, and the retaining ring 17 compresses the spring 12.

[0061] The first engaging portion 14 of the limiting sleeve 11 continues to slide on the first connecting portion 13, that is, the first toothed post slides on the first groove, until the second engaging portion 16 leaves the second connecting portion 15.

[0062] Rotate the limiting sleeve 11 clockwise to rotate the nut 7 and the adjusting rod 8. Since the adjusting rod 8 is threadedly engaged with the connecting sleeve 6, the adjusting rod 8 extends into the valve core 2 while rotating, causing the end of the adjusting rod 8 to move into the air inlet 5.

[0063] Because one end of the adjusting rod 8 that extends into the valve core 2 is frustoconical, as the adjusting rod 8 extends into the air inlet 5, the gas passage between the outer surface of the adjusting rod 8 and the inner wall of the air inlet 5 gradually decreases, slowing down the gas flow rate. Until the sealing ring 10 moves into the air inlet 5, the inner wall of the air inlet 5 will compress the sealing ring 10, completely sealing the end of the air inlet 5, preventing gas from escaping.

[0064] Conversely, rotating the limiting sleeve 11 counterclockwise moves the end of the adjusting rod 8 away from the air inlet 5, thereby increasing the gas flow rate.

[0065] After adjusting the gas flow rate, release the limiting sleeve 11 by hand. The spring 12 will push the retaining ring 17 to move away from the button 7, causing the limiting sleeve 11 to move. This allows the first locking part 14 to slide on the first connecting part 13, that is, the first toothed post to slide on the first groove.

[0066] The limiting sleeve 11 moves the second locking part 16 onto the second connecting part 15, that is, the second toothed post moves into the second groove. Thus, the limiting sleeve 11 is positioned on the connecting sleeve 6 through the cooperation of the second toothed post and the second groove, thereby positioning the button 7 and the adjusting rod 8.

[0067] Since adjusting the gas flow only requires the end of the adjusting rod 8 to block the end of the air inlet 5 or to move the end of the adjusting rod 8 out of the air inlet 5, the adjusting rod 8 does not need to move too far. Therefore, the first locking part 14 is always located on the first connecting part 13 throughout the adjustment process.

[0068] Example 2: Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the valve core 2 and the connecting sleeve 6 are integrally formed. This integral forming shortens the assembly time while improving the overall strength and durability of the components.

[0069] Example 3: As Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the connection between each second protrusion and the outer surface of the connecting sleeve 6 consists of two inclined straight lines, and the two straight lines on each second protrusion approach each other from one end near the valve body 1 to the other end, so that the two sides of each second groove are also inclined straight lines. The shape of the second toothed post is adapted to the shape of the second groove.

[0070] Working principle: When the second locking part 16 slides onto the second connecting part 15, since the sides of the second tooth post and the second groove are both inclined, the second groove automatically guides the second tooth post so that the second tooth post can automatically align itself on the second groove.

[0071] Example 4: Figure 11 As shown, the difference between this embodiment and embodiment 3 is that an annular clearance groove 18 is provided on the outer surface of the connecting sleeve 6 at the end of the second connecting part 15.

[0072] Working principle: When the second locking part 16 slides onto the second connecting part 15, the clearance groove 18 allows the second tooth post to be inserted to a greater extent, forming a fit.

[0073] Example 5: Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that the connection between each second protrusion and the outer surface of the connecting sleeve 6 consists of two inclined straight lines, and the two straight lines on each second protrusion gradually approach each other from one end near the valve body 1 to the other end. This makes the two sides of each second groove also inclined straight lines. The shape of the second toothed post matches the shape of the second groove, and the number of second toothed posts is equal to the number of second grooves and corresponds one-to-one.

[0074] Working principle: When the second locking part 16 slides onto the second connecting part 15, since the sides of the second tooth post and the second groove are both inclined, the second groove automatically guides the second tooth post so that the second tooth post can automatically align on the second groove, and the second tooth post and the second groove correspond one-to-one.

[0075] Example 6: As Figure 13 As shown, the difference between this embodiment and Embodiment 1 is that: a stepped groove is provided at one end of the limiting sleeve 11 that mates with the connecting sleeve 6, and the second snap-fit ​​part 16 is fixedly disposed on the end face of the stepped groove. That is, several second toothed posts are evenly fixedly connected to the end face of the stepped groove.

[0076] The second connecting part 15 is fixedly disposed on the end face of the connecting sleeve 6. That is, several second protrusions are evenly fixedly connected to the end face of the connecting sleeve 6, wherein the connecting sleeve 6 is fixed to the end of the valve core 2, so that the connecting sleeve 6 and the valve core 2 are separate structures.

[0077] like Figure 14 As shown, the connecting sleeve 6 and the valve core 2 are integrally formed.

[0078] Working principle: When the second locking part 16 slides onto the second connecting part 15, the stepped groove part at the end of the limiting sleeve 11 is fitted onto the connecting sleeve 6, so that the second toothed post is locked onto the second groove.

[0079] Example 7: As Figure 15 As shown, the difference between this embodiment and Embodiment 1 is that the second snap-fit ​​part 16 is fixedly disposed on the end face of the limiting sleeve 11. That is, a plurality of second toothed posts are uniformly fixedly connected to the end face of the limiting sleeve 11.

[0080] The second connecting part 15 is fixedly disposed on the end face of the connecting sleeve 6. That is, several second protrusions are evenly fixedly connected to the end face of the connecting sleeve 6, wherein the connecting sleeve 6 is fixed to the end of the valve core 2, so that the connecting sleeve 6 and the valve core 2 are separate structures.

[0081] like Figure 16 As shown, the connecting sleeve 6 and the valve core 2 are integrally formed.

[0082] Working principle: When the second engaging part 16 moves to the second connecting part 15, the second toothed post engages with the second groove.

[0083] Example 8: The difference between this example and Example 1 is that: a stepped groove is provided at the end of the limiting sleeve 11 that mates with the connecting sleeve 6, and an annular groove is provided on the inner wall of the stepped groove. An annular rubber ring is fixedly connected to the outer surface of the end of the connecting sleeve 6.

[0084] Working principle: When the second snap-fit ​​part 16 moves to the second connecting part 15, the inner wall of the stepped groove squeezes the rubber ring until the rubber ring is stuck in the ring groove.

[0085] Example 9: The difference between this example and Example 1 is that: a stepped groove is provided at the end of the limiting sleeve 11 that mates with the connecting sleeve 6, and an annular rubber ring is fixedly connected to the inner wall of the stepped groove. An annular groove is provided on the outer surface of the end of the connecting sleeve 6.

[0086] Working principle: When the second snap-fit ​​part 16 moves to the second connecting part 15, the rubber ring is squeezed by the outer surface of the connecting sleeve 6 until the rubber ring is stuck in the ring groove.

[0087] Although the present invention 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
