Description

Technical Field

[0001] The invention relates to the technical field of electromechanical structure fixing connectors, in particular to a limited space electromechanical structure fixing connector for air conditioning and ventilation. Background Art

[0002] Axial flow fans are often used in air conditioning and ventilation ducts in limited spaces because of their low cost, stability and convenience;

[0003] The fan blades and the motor are often connected by a coupling. In order to reduce vibration, the fan blades should be installed as close to the motor as possible to reduce the harmful vibration to the motor caused by the change in the moment of inertia when the fan blades are attached with debris;

[0004] However, as we all know, the axial flow fan is driven by the rotation of the fan blades to drive the airflow. That is to say, the airflow is smallest at the rotation center of the fan blades, that is, the fastening position of the motor. Therefore, the heat generated by the motor after a long period of rotation is not easy to dissipate, and heat will accumulate between the blades in a limited space, that is, heat accumulation. Figure 1 As shown, therefore, axial flow fans often need auxiliary cooling. In a limited space, it is difficult to add too much cooling equipment to ensure the flow of air. Moreover, in the air-conditioning pipeline, due to the relatively dirty gas, the fan is prone to a large amount of flocculent dust during long-term operation, which further makes the cooling of the fan more urgent.

[0036] See also Figure 1-14The present invention provides a technical solution: a limited space electromechanical structure fixed connector for air conditioning and ventilation, comprising a temperature sensor, a housing 1, a motor 2 and a connecting end 3, the connecting end 3 is rotatably connected to the inside of the housing 1 through a connecting rod 40, a blade is fixedly connected to the connecting end 3, a support member 4 is fixedly connected to the output shaft of the motor 2, a driving ring 5 is arranged on the left side of the support member 4, the driving ring 5 is slidably connected to the right side wall of the motor 2, and support groups are arranged above and below the motor 2;

[0037] The support group includes a fixed rod 6 and a sliding rod 18. The top of the fixed rod 6 is slidably connected with a slide groove 7. The slide groove 7 is opened on the inner wall of the shell 1. A notch is opened on the fixed rod 6. A driving rod 8 is arranged inside the notch. A cylinder 9 is fixedly connected between the left end of the driving rod 8 and the inner wall of the shell 1. A limiting groove 10 is opened on the fixed rod 6. A vertical rod 11 is slidably connected inside the limiting groove 10. A first spring 12 is fixedly connected between the vertical rod 11 and the top wall of the limiting groove 10. A driving block 13 is fixedly connected to the top of the vertical rod 11. The driving block 13 is trapezoidal. A first contact block 14 is arranged directly above the driving block 13. A The second contact block 15, the first contact block 14 and the second contact block 15 are all wedge-shaped, and the second contact block 15 and the first contact block 14 are fixedly connected to the driving rod 8. A push rod 16 is arranged inside the vertical rod 11, and the push rod 16 can move synchronously with the vertical rod 11. The bottom end of the push rod 16 is rotatably connected to the support rod 17, and the bottom end of the support rod 17 is rotatably connected to the driving ring 5. The sliding rod 18 is slidably connected to the support member 4, and the sliding rod 18 and the inner wall bracket of the support member 4 are fixedly connected with the fifth spring 39. A clamping block 19 is arranged on the right side of the sliding rod 18, and the clamping block 19 is rotatably connected to the support member 4. A torsion spring 20 is sleeved on the rotating shaft of the clamping block 19.

[0038] The left end of the slide rod 18 is rotatably connected with a ball bearing 21 .

[0039] Rollers 25 are rotatably connected to the first contact block 14 and the second contact block 15 .

[0040] like Figure 2-5 as well as Figure 7-Figure 9 As shown:

[0041] The temperature sensor is set at any position on the right side of the motor 2, and the position of the temperature sensor can detect the temperature of the area between the motor 2 and the connection terminal 3;

[0042] When the housing 1 is installed inside the pipe 41, the fixing rod 6 is at the rightmost side of the slide slot 7. At this time, the first contact block 14 is below the driving block 13 and presses down the driving block 13, so that the vertical rod 11 is at the bottom of the limit slot 10, that is, at this time, the first spring 12 is in a state of being stretched to the limit, and at this time, the push rod 16 pushes the driving ring 5 to slide to the right along the motor 2 to the limit through the support rod 17, and then at this time, the slide rod 18 stretches the fifth spring 39 and pushes the clamping block 19 to the right, so that the clamping block 19 can rotate around the rotation axis to a state of tightly clamping the connecting end 3, and at this time, the torsion spring 20 is compressed;

[0043] At this time, as the motor 2 rotates, its rotating shaft will drive the support member 4 to rotate. During the rotation of the support member 4, the driving ring 5 is in continuous contact with the ball 21 at the left end of the slide bar 18. The ball 21 reduces the friction between the support member 4 and the slide bar 18, so that the slide bar 18 can continuously push the clamping block 19, so that the connection end 3 rotates in the clamped state, and the connection end 3 rotates inside the housing 1 through the connecting rod 40, and at this time, the air inside the pipe 41 is transported to the right side;

[0044] When the motor 2 works for a long time, the area between the output shaft of the motor 2 and the connection end 3 will generate high temperature without being blown by the conveyed airflow. The temperature rise will be monitored by the temperature sensor. The temperature sensor can be any one of the existing technologies. In this case, it needs to be cooled.

[0045] The cooling works as follows:

[0046] When the temperature sensor detects high temperature, it will start the cylinder 9, which will shorten and drive the driving rod 8 to move from the rightmost side to the leftmost side. At this time, the first contact block 14 is at the rightmost side above the driving block 13, so at this time, the first contact block 14 will first slide to the left along the top of the driving block 13 when following the movement of the driving rod 8. When the horizontal plane at the bottom of the first contact block 14 passes over the horizontal plane at the top of the driving block 13, the inclined surface of the first contact block 14 will gradually contact the inclined surface of the driving block 13, and the first contact block 14 is rotatably connected to the The roller 25 can reduce the friction between the first contact block 14 and the driving block 13. At this time, the driving block 13 will pull the vertical rod 11 to slide up along the limit groove 10 under the elastic reset action of the first spring 12. At this time, the vertical rod 11 will drive the push rod 16 to rise. The rising push rod 16 will pull the driving ring 5 to slide to the left along the side wall of the motor 2 through the support rod 17. During the movement of the driving ring 5 to the left, the sliding rod 18 will be synchronously pulled to slide to the left on the support member 4 following the driving ring 5 under the elastic reset action of the fifth spring 39.

[0047] When the slide bar 18 moves to the left, the torsion spring 20 will gradually elastically reset to drive the clamping block 19 to disengage from the contact with the connection end 3, thereby releasing the clamping of the connection end 3. At this time, the connection end 3 will continue to rotate under the action of inertia. At this time, the clamping block 19 has been separated from the connection end 3, that is, the rotation frequency of the motor 2 will be different from the frequency of the connection end 3 continuing to rotate under the action of inertia. At this time, the first contact block 14 will also maintain contact with the driving block 13 and gradually move to the left, until the first contact block 14 is completely separated from the driving block 13, and then the vertical rod 11 will slide up to the highest position;

[0048] After the first contact block 14 is out of contact with the driving block 13, the driving block 13 will be in the middle position between the first contact block 14 and the second contact block 15. At this time, the cylinder 9 continues to pull the driving rod 8 to move. At this time, when the second contact block 15 moves to the left, the contact between the roller 25 and the driving block 13 will force the driving block 13 and the vertical rod 11 to move to the left, thereby causing the fixed rod 6 and the motor 2 to move to the left synchronously. At this time, the fixed rod 6 will slide to the left along the slide groove 7, and the support member 4 will move to the left relative to the connecting end 3, so that the heat accumulation area between the right end of the motor 2 and the left end of the connecting end 3 will become larger;

[0049] When the fixed rod 6 slides to the leftmost side of the slide slot 7, the fixed rod 6, the vertical rod 11 and the driving block 13 will stop, but at this time the driving rod 8 will move to the left relative to the stationary fixed rod 6 inside the notch, that is, at this time the second contact block 15 will move toward the driving block 13, and when the two are in contact, the roller 25 will press down on the driving block 13, and then the vertical rod 11 will slide down along the limiting groove 10 and stretch the first spring 12, then the vertical rod 11 and the push rod 16 will drop, and when the second contact block 15 rises to the top of the driving block 13, the support rod 17 will definitely push The dynamic driving ring 5 slides to the right along the motor 2, thereby pushing the slide bar 18 to slide to the right along the support member 4. At this time, the fifth spring 39 will be stretched and will push the clamping block 19 to rotate around the rotating shaft and compress the torsion spring 20. At this time, the clamping block 19 will clamp the connecting end 3 here, but at this time, the clamping will be close to the left end of the connecting end 3. After the motor 2 moves to the extreme position to the left relative to the connecting end 3, the contact between the heat accumulation area between the motor 2 and the external cold air will increase, so that the heat accumulation area between the motor 2 and the connecting end 3 will be reduced, thereby facilitating cooling;

[0050] When the second contact block 15 rises to the top of the driving block 13, it will continue to slide to the left along the horizontal plane at the top of the driving block 13 for a short distance and then stop. At this time, the cylinder 9 is shortened to the limit. At this time, the clamping block 19 clamps the connecting end 3, thereby quickly making the connecting end 3 and the output shaft of the motor 2 have the same rotation frequency;

[0051] Moreover, clamping is adopted instead of sliding between the connection end 3 and the output shaft of the motor 2 to complete the relative movement between the motor 2 and the connection end 3. The advantage is that if sliding is adopted, the output shaft of the motor 2 and the connection end 3 can only adopt the sliding mode of interference fit, but this sliding mode has large friction and the sliding is not smooth. If clearance fit is adopted, impurities will be generated in the gap between the output shaft of the motor 2 and the connection end 3, thereby affecting normal use. Moreover, when clearance fit is adopted, the gap between the output shaft of the motor 2 and the connection end 3 will cause the output shaft of the motor 2 to twist during the initial rotation, thereby increasing the load and reducing the service life.

[0052] In the present invention, when heat dissipation is required, the motor 2 moves to the left relative to the connection end 3, and the contact between the heat accumulation area therebetween and the external cold air will increase, so that the heat accumulation area between the motor 2 and the connection end 3 will be reduced, thereby facilitating cooling, and the synchronous rotation of the motor 2 and the connection end 3 is completed by the clamping of the clamping block 19. When the motor 2 quickly moves to the leftmost side and the clamping block 19 clamps the connection end 3, although the distance between the motor 2 and the connection end 3 will be extended, it can still stably and quickly resume rotation under the clamping of the clamping block 19, and the frequency of vibration is reduced;

[0053] That is, when heat dissipation is performed, the fixing rod 6 is at the leftmost position of the slide slot 7, and the motor 2 continues to drive the connecting end 3 to rotate. When heat dissipation is completed, the motor 2 needs to be reset to the initial optimal position to enable it to work normally;

[0054] The reset works as follows:

[0055] When the temperature sensor detects that the temperature drops to a specified level, it will drive the cylinder 9 to extend, and the cylinder 9 will drive the driving rod 8 to move to the right. At this time, the second contact block 15 and the roller 25 will slide to the right along the top of the driving block 13. When the second contact block 15 passes over the top of the driving block 13, the roller 25 will contact the inclined right side wall of the driving block 13. At this time, the vertical rod 11 gradually rises under the pull of the first spring 12, and the clamping block 19 releases the connection end 3 again under the cooperation of the push rod 16, the support rod 17, the driving ring 5 and the sliding rod 18. The driving block 13 will then move relatively to a position between the first contact block 14 and the second contact block 15, and then the first contact block 14 will push the vertical rod 11, the push rod 16 and the fixed rod 6 to move to the right. When the fixed rod 6 moves to the right to the limit, the first contact block 14 will press down the driving block 13, so that it can drop again, and then the clamping block 19 will clamp the position close to the right side of the connecting end 3 (this reset work and the reference cooling work process), and at this time, the motor 2 continues to rotate synchronously with the connecting end 3.

[0056] A slider 22 is slidably connected inside the clamp block 19 , a second spring 23 is fixedly connected between the slider 22 and the inner top wall of the clamp block 19 , and a contact wheel 24 is rotatably connected to the slider 22 .

[0057] like Figure 6 As shown:

[0058] Since the extension and contraction of the cylinder 9 are both in a rapid state, when the clamping block 19 first releases the clamping of the connection end 3 and then clamps the connection end 3 again, the connection end 3 is in a rotating state. Therefore, when the clamping block 19 clamps the connection end 3 rapidly, the connection end 3 will generate greater friction on the clamping block 19 in the rapid rotating state.

[0059] Through the cooperation between the slider 22 and the second spring 23, when the clamping block 19 is separated from the connection end 3, the elastic expansion of the second spring 23 will push the slider 22 to continue to maintain a short range of contact with the contact wheel 24, and when the clamping block 19 is separated from the connection end 3, the contact wheel 24 will rotate under the contact with the connection end 3, and the friction force of the rotation axis of the contact wheel 24 is relatively large, so in the process of the contact wheel 24 following the rotation of the connection end 3, the rotation speed of the connection end 3 can be reduced by the relatively large friction force of the rotation axis of the contact wheel 24;

[0060] However, before the clamping block 19 clamps the connection end 3, the contact wheel 24 will first contact the connection end 3, thereby once again reducing the rotation speed of the connection end 3. Therefore, when the clamping block 19 clamps the connection end 3, the friction generated can be reduced.

[0061] The vertical rod 11 is slidably connected with the push rod 16, a third spring 26 is fixedly connected between the vertical rod 11 and the top of the push rod 16, a first rack rod 27 is fixedly connected to the side wall of the push rod 16, the first rack rod 27 is meshed with a one-way gear 28, the one-way gear 28 is rotatably connected to the side wall of the vertical rod 11, a pressure rod 29 is provided on one side of the top of the push rod 16, a plug rod 30 is slidably connected to the pressure rod 29, a fourth spring 32 is fixedly connected between the plug rod 30 and the inner wall of the fixed rod 6, a cam 33 is provided above the plug rod 30, the cam 33 is rotatably connected to the fixed rod 6, a strong spring 31 is fixedly connected between the plug rod 30 and the pressure rod 29, and the strong spring 31 is sleeved on the plug rod 30;

[0062] A driving group is arranged above the cam 33 , and the driving group is used to drive the cam 33 to rotate when the fixing rod 6 moves to the outermost side of the sliding groove 7 .

[0063] like Figure 3 , 7 , Fig.10 and Fig.11 As shown:

[0064] When the clamping block 19 rotating with the motor 2 clamps the connecting end 3 rotating under inertia, although the friction equivalent of the end of the clamping block 19 can be slowed down by the cooperation of the contact wheel 24, the second spring 23 and the slider 22, friction is still inevitable. When the end of the clamping block 19 is damaged due to friction, the vertical rod 11 and the push rod 16 are lowered by a fixed distance, and the driving ring 5 pushes the slide rod 18 to move a fixed distance. Then, when the end of the clamping block 19 is damaged, the slide rod 18 will not be able to stably fit with the connecting end 3 after pushing the clamping block 19 to rotate a fixed distance, thereby causing the clamping block 19 to be unstable on the connecting end, so that the connecting end 3 cannot rotate stably.

[0065] Therefore, when the fixing rod 6 slides to the far left or far right along the slide slot 7, the cylinder 9 is not extended or shortened to the limit at this time, so the first contact block 14 or the second contact block 15 will slide on the top of the driving block 13. However, when the first contact block 14 or the second contact block 15 is above the driving block 13, it means that the clamping block 19 is in contact with the connecting end 3 and the connecting end 3 is clamped when there is no loss at the end of the clamping block 19.

[0066] However, if the end of the clamping block 19 is lost, it cannot be clamped effectively. Therefore, after the first contact block 14 or the second contact block 15 moves to the extreme left or right, the driving group will control the cam 33 to rotate one circle. Before the cam 33 rotates, its pressing end is in a vertical position. When the cam 33 rotates, it will press down the insertion rod 30. The insertion rod 30 will slide down along the fixed rod 6 and compress the fourth spring 32. When the insertion rod 30 descends, it will press down the pressure rod 29 through the strong spring 31. The elastic force of the strong spring 31 is relatively large, and the pressure rod 29 will press down the top of the push rod 16. Then, if the clamping block 19 is worn out and does not contact the connecting end 3, it means that the sliding rod 18 can move toward The clamping block 19 continues to move in the direction of rotation, that is, the driving ring 5 can continue to slide along the side wall of the motor 2. At this time, the push rod 16 will slide down along the vertical rod 11 and stretch the third spring 26. The third spring 26 is used to continuously pull up the push rod 16, thereby preventing the push rod 16 from descending under its own gravity. When the push rod 16 slides down, the first rack rod 27 will mesh with the one-way gear 28, and the one-way gear 28 can rotate tightly when the push rod 16 descends. Therefore, if the end of the clamping block 19 is worn out, the push rod 16 will slide down, thereby ensuring that the clamping block 19 can rotate to contact with the connecting end 3 and clamp the connecting end 3, thereby compensating for the wear of the clamping block 19.

[0067] If there is no wear on the end of the clamping block 19, when the cam 33 rotates one circle and returns to the initial state, the strong spring 31 will be compressed when the insertion rod 30 drives the pressure rod 29 to press the push rod 16 downward.

[0068] Embodiment 1: The driving group includes a second motor 37 , which is embedded in the fixing rod 6 , and the output shaft of the second motor 37 is rotationally connected to the cam 33 .

[0069] like Fig.10 and Fig.11 As shown:

[0070] The second motor 37 is controlled by a sensor arranged on one side of the first contact block 14 or the second contact block 15. The sensor can be any one of the prior art, and is used to control the rotation of the second motor 37 after the first contact block 14 or the second contact block 15 moves to the extreme extent on the left or right side, and then the second motor 37 drives the cam 33 to rotate to press the insertion rod 30 downward.

[0071] Embodiment 2: The driving group includes a driving gear 34, a chain 38 is transmission-connected between the rotating shaft of the driving gear 34 and the rotating shaft of the cam 33, the driving gear 34 is rotationally connected to the fixed rod 6, a second rack rod 35 is meshed above the driving gear 34, and the second rack rod 35 is fixedly connected to the driving rod 8.

[0072] As a further solution of the present invention, a third rack rod 36 is provided on the right side of the second rack rod 35 , the third rack rod 36 is fixedly connected to the driving rod 8 , and the third rack rod 36 and the second rack rod 35 are symmetrically arranged about the driving block 13 .

[0073] like Figure 12-14 As shown:

[0074] A second rack bar 35 and a third rack bar 36 may be provided, such as Fig.14 , before the driving block 13 is at the leftmost side of the top of the driving block 13, the clamping block 19 is clamped with the connecting end 3, and when the first contact block 14 moves from the rightmost side to the leftmost side on the driving block 13, the second rack rod 35 will gradually disengage from the driving gear 34 and drive the driving gear 34 to rotate. Before the first contact block 14 moves from the rightmost side to the leftmost side on the driving block 13, the second rack rod 35 will disengage from the driving gear 34, and during the rotation of the driving gear 34, the chain 38 drives the rotating shaft of the cam 33 to rotate, and the cam 33 presses down the insertion rod 30. At this time, if the end of the clamping block 19 is worn, the push rod 16 will slide down a corresponding distance along the vertical rod 11. If the clamping block 19 is not worn, the strong spring 31 will be compressed, but it will not affect the clamping of the clamping block 19 on the connecting end 3.

[0075] When the fixing rod 6 moves to the rightmost side, the second contact block 15 presses down the driving block 13 and its top end moves to the rightmost side of the top of the driving block 13. At this time, the third rack rod 36 moves to engage with the driving gear 34 and drives the cam 33 to rotate through the chain 38, thereby causing the insertion rod 30 to drop again, thereby compensating when the end of the clamping block 19 is worn.
