Description

Technical Field

[0001] This invention relates to the field of coupling technology, specifically a connector. Background Technology

[0002] During the transmission process between the input and output shafts, it is difficult for the axes of the input and output shafts to be aligned during installation. With long-term high-speed rotation, the concentricity between the two shafts deteriorates, and the connector often needs to cope with sudden torque changes between the shafts. Under the action of sudden torque changes, the connector will vibrate or circumferentially misalign, which will lead to the connector breaking.

[0003] For example, Chinese Patent Publication No. CN215058979U discloses a safety coupling, including a first half-coupling and a second half-coupling. Both the first and second half-couplings are connected to a shaft structure. Both the first and second half-couplings include a torque buffer structure, a connecting locking structure, and a fixing part. Under conditions of sudden changes in torque value and direction, the first and second half-couplings undergo circumferential misalignment. The slider structure slides relative to the disc-shaped body under the support of a first spring structure. The first spring structure acts as a buffer, protecting the coupling from damage under conditions of sudden torque changes.

[0004] This solution uses an elastic structure to mitigate circumferential misalignment caused by sudden torque changes, which can prevent coupling breakage to some extent. However, the buffering capacity of the elastic structure is limited. When the device continues to operate in a high-speed rotating and unstable environment, the spring structure may be unable to mitigate the circumferential misalignment and vibration caused by sudden torque changes. If the device continues to operate in this case, it may still breakage. Summary of the Invention

[0005] The purpose of this invention is to provide a connector to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

An input shaft is fixedly connected to the inner cavity of one end of the first connecting block, and an output shaft is fixedly connected to the inner cavity of one end of the second connecting block. A turntable is fixedly connected to the middle of the end of the first connecting block away from the input shaft.

The output end of the transmission assembly is engaged with the side wall of the inner cavity of the turntable. A protective mechanism is provided on the outside of the transmission assembly. When the first connecting block and the second connecting block misalign circumferentially, the end of the protective mechanism drives the transmission assembly, causing its output end to gradually move away from the turntable, thereby cutting off the transmission between the first connecting block and the second connecting block.

[0010] As a further embodiment of the present invention: a locking block is fixedly connected to the end of the rotating column away from the mounting block, and a locking groove for use with the locking block is opened in the middle of the side of the second connecting block near the rotating column. A rubber pad is provided in the inner cavity of the locking groove. Both the locking block and the rubber pad are cross-shaped, and the outer wall of the locking block fits into the inner cavity of the rubber pad.

[0011] As a further embodiment of the present invention: the protective mechanism includes symmetrically arranged movable rods, the ends of which are rotatably connected to the outer cylinder via bearings sleeved around the outer cylinder. An installation groove for accommodating the bearing is formed on the outer wall of the outer cylinder. The movable rods are rotatably engaged with the outer cylinder via the bearings. A toothed block is fixedly connected to the upper part of the movable rod near the turntable. Multiple sets of arc-shaped teeth are provided on the opening edge of the turntable facing the second connecting block. The ends of the toothed blocks are movably engaged between two adjacent sets of arc-shaped teeth. A through groove is formed in the middle of the movable rod, and a connecting rod is slidably connected to the inner cavity of the through groove. The end of the connecting rod away from the movable rod is fixedly connected to the side of the second connecting block near the outer cylinder. A baffle is fixedly connected to the end of the connecting rod near the turntable.

[0012] As a further aspect of the present invention: the baffle is an elastic plate, both the baffle and the through groove are rectangular and the length of the baffle is greater than the length of the through groove while their heights are equal, the distance from the side of the connecting rod away from the second connecting block to the turntable is greater than the distance from the side of the moving rod away from the second connecting block to the turntable, and a limiting member for limiting the moving rod is provided on the upper part of the connecting rod near the turntable.

[0013] As a further embodiment of the present invention: the limiting member includes a base, the base is disposed in the inner cavity of the connecting rod, the lower end of the base is elastically connected to the inner cavity of the connecting rod by a spring, symmetrical sliders are fixedly connected to both sides of the base, a groove for cooperating with the slider is opened on the side wall of the inner cavity of the connecting rod, a limiting block is fixedly connected to one side of the upper end of the base, a button is fixedly connected to the side of the upper end of the base away from the limiting block, and a driven block is fixedly connected to the top wall of the inner cavity of the through groove.

[0014] As a further embodiment of the present invention: the button is L-shaped and consists of a horizontal part and a vertical part. A symmetrical balance rod is fixedly connected to the lower end of the horizontal part near the limiting block. The balance rod is slidably connected to the connecting rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By combining a rotating component with a protective mechanism, when the connector experiences minor vibrations or circumferential misalignment during transmission, the toothed block moves relative to the two teeth of the arc-shaped tooth, pushing the outer cylinder away from the turntable. This creates a gap between the moving block and the top wall of the groove, and the compression of the spring counteracts the force caused by the misalignment. The spring's rebound then brings the block back into close contact with the turntable. When there is significant vibration or circumferential misalignment, i.e., when the toothed block and the tip of the arc-shaped tooth come into contact, the moving rod travels a larger distance, and the outer cylinder also travels a greater distance. The limiting component on the connecting rod limits the moving rod, preventing the outer cylinder from rebounding under the spring's action. This completely separates the moving block from the turntable, preventing it from closing tightly again, thus cutting off the transmission between the first and second connecting blocks. This prevents the connector from breaking under high-speed rotation and unstable conditions. Attached Figure Description

[0031] Please see Figure 1-3 In this embodiment of the invention, a connector includes a first connecting block 1 and a second connecting block 2. An input shaft is fixedly connected to the inner cavity of the first connecting block 1 away from the second connecting block 2, and an output shaft is fixedly connected to the inner cavity of the second connecting block 2 away from the first connecting block 1. A turntable 3 is fixedly connected to the middle of the end of the first connecting block 1 away from the input shaft. A transmission assembly 5 for transmitting power from the input shaft to the output shaft is provided between the second connecting block 2 and the turntable 3. The output end of the transmission assembly 5 is engaged with the inner cavity sidewall of the turntable 3. A protective mechanism 4 is provided on the outside of the transmission assembly 5. When the first connecting block 1 and the second connecting block 2 experience circumferential misalignment, the end of the protective mechanism 4 drives the transmission assembly 5, causing its output end to gradually move away from the turntable 3, thereby cutting off the transmission between the first connecting block 1 and the second connecting block 2.

[0032] The transmission assembly 5 includes a rotating column 55, with a locking block 9 fixedly connected to one end of the rotating column 55. A second connecting block 2 has a slot in its center near the rotating column 55 for use with the locking block 9. A rubber pad 8 is provided inside the slot. Both the locking block 9 and the rubber pad 8 are cross-shaped, and the outer wall of the locking block 9 fits snugly against the inner cavity of the rubber pad 8. By providing a thicker rubber pad 8 between the locking block 9 and the second connecting block 2, wear between the locking block 9 and the second connecting block 2 can be reduced during the rotation of the rotating column 55, thereby extending the service life of the device. A mounting block 56 is fixedly connected to the end of the rotating column 55 away from the locking block 9. The end of the mounting block 56 away from the rotating column 55 is rotatably connected to the side of the inner cavity of the turntable 3 away from the first connecting block 1. Symmetrical guide plates 57 are fixedly connected to both sides of the mounting block 56, and the guide plates 57 are connected to the side plates of the inner cavity of the turntable 3. A sliding connection is made, with an outer cylinder 51 movably connected to the outer wall of the rotating column 55 near the mounting block 56. The outer cylinder 51 is elastically connected to the second connecting block 2 via a spring on the side away from the mounting block 56. The end of the spring away from the second connecting block 2 is in contact with the outer cylinder 51. The spring is sleeved on the outer wall of the rotating column 55 and continuously provides a pushing force to the outer cylinder 51, causing the outer cylinder 51 to move away from the second connecting block 2. A connecting rod 52 is symmetrically arranged at the end of the outer cylinder 51 near the mounting block 56. The connecting rod 52 is rotatably connected to the outer wall of the outer cylinder 51, and the vertical plane of the connecting rod 52 is parallel to the vertical plane of the guide plate 57. A moving key 53 is rotatably connected to the end of the connecting rod 52 away from the outer cylinder 51. The moving key 53 is slidably connected to the inner cavity of the guide plate 57, and the moving key 53 will only move vertically within the groove formed between the two sets of guide plates 57.

[0033] When the turntable 3 rotates, grooves 31 are symmetrically provided on the inner side of the turntable 3. Since the spring always gives the outer cylinder 51 a thrust away from the second connecting block 2, the outer cylinder 51 will fit against the mounting block 56, and push the moving key 53 through the connecting rod 52, so that the moving key 53 is engaged with the groove 31. At this time, the turntable 3 will rotate through the moving key 53. The moving key 53 drives the connecting rod 52 to rotate, and the connecting rod 52 drives the outer cylinder 51 to rotate. Since the guide plate 57 and the moving key 53 are in contact, the moving key 53 drives the guide plate 57 to rotate, thereby driving the mounting block 56 to rotate. The mounting block 56 will then drive the rotating column 55 to rotate, thereby driving the second connecting block 2 to rotate through the rotating column 55. Thus, the power transmitted by the input shaft can be transmitted to the second connecting block 2, so that the output shaft rotates with the input shaft.

[0034] The protective mechanism 4 includes symmetrically arranged movable rods 43. The ends of the movable rods 43 are rotatably connected to the outer cylinder 51 via bearings 44 sleeved around the outer cylinder 51. The outer wall of the outer cylinder 51 has a mounting groove 54 for accommodating the shaft 44. The movable rods 43 and the outer cylinder 51 rotate in cooperation via the bearings 44. A toothed block 42 is fixedly connected to the upper part of the movable rod 43 near the turntable 3. The turntable 3 has multiple sets of arc-shaped teeth 41 on the opening edge facing the second connecting block 2. The ends of the toothed blocks 42 are movably engaged between two adjacent sets of arc-shaped teeth 41. That is, the turntable 3 will drive the arc-shaped teeth 41 to rotate. The arc-shaped teeth 41 drive the movable rod 43 and the rotating column 55 to rotate synchronously through the toothed blocks 42 engaged with them. The movable rods 43 are not set for transmission, but so that when the toothed blocks 42 on the movable rod 43 and the arc-shaped teeth 41 misalign, the movable rod 43 is pushed by the arc-shaped teeth 41, thereby driving the outer cylinder 51 to slide on the rotating column 55. A toothed block is opened in the middle of the movable rod 43. A through groove 45 has a connecting rod 10 slidably connected to its inner cavity. The end of the connecting rod 10 away from the moving rod 43 is fixedly connected to the side of the second connecting block 2 near the outer cylinder 51. A baffle 7 is fixedly connected to the end of the connecting rod 10 near the turntable 3. The baffle 7 is an elastic plate. Both the baffle 7 and the through groove 45 are rectangular, and the length of the baffle 7 is greater than the length of the through groove 45 while their heights are equal. The distance from the side of the connecting rod 10 away from the second connecting block 2 to the turntable 3 is greater than the distance from the side of the moving rod 43 away from the second connecting block 2 to the turntable 3. That is, when the toothed block 42 and the arc-shaped tooth 41 are engaged, there is a gap between the baffle 7 and the moving rod 43. When the first connecting block 1 and the second connecting block 2 are not installed and fixed to the shaft, since both ends of the device are movable, the baffle 7 can be picked up at any end when the connector is taken out of the packaging, and the other end will also be taken out of the packaging box without having to be picked up multiple times.

[0035] When no sudden torque change causes vibration or circumferential misalignment during device operation, the first connecting block 1 and the second connecting block 2 rotate synchronously, and the moving rod 43 and the outer cylinder 51 also rotate synchronously. However, when vibration or circumferential misalignment occurs in the first connecting block 1 and the second connecting block 2 during transmission, there are two scenarios. One scenario is when the amplitude of vibration or misalignment is small. In this case, the force of the first connecting block 1 acts directly on the arc-shaped tooth 41 through the turntable 3, while the force of the second connecting block 2 acts on the toothed block 42 of the moving rod 43 through the connecting rod 10. Therefore, vibration or circumferential misalignment will also occur. This is directly reflected in the arc-shaped tooth 41 and the tooth block 42. The arc-shaped tooth 41 and the tooth block 42 will move relative to each other. At this time, the tooth block 42 will move relative to the two teeth of the arc-shaped tooth 41. That is, the end of the tooth block 42 away from the moving rod 43 will not contact the tip of the arc-shaped tooth 41. Since the arc-shaped tooth 41 is fixedly connected to the turntable 3, the tooth block 42 will gradually move away from the turntable 3. The force on the tooth block 42 will be transmitted to the outer cylinder 51 through the moving rod 43 and the bearing 44. The outer cylinder 51 will then be pushed away from the turntable 3, and the spring will be compressed accordingly. The sudden change in torque is achieved through the compression of the spring. The forces generated during vibration and misalignment cancel each other out, thus preventing the force from directly acting on the connector and causing damage. Another scenario occurs when the vibration or misalignment is too large. In this case, the relative movement distance between the tooth block 42 and the arc-shaped tooth 41 is large, meaning that the end of the tooth block 42 away from the moving rod 43 may contact the tip of the arc-shaped tooth 41. In this situation, the elasticity of the spring alone cannot counteract the sudden torque force, and the connector operation becomes unstable. Continuing to operate under this high-speed rotation and vibration condition may cause the connector to break. To avoid this situation, especially in the connection... A limiting member 6 is provided on the rod 10 to limit the movement rod 43. When the end of the toothed block 42 away from the movement rod 43 contacts the tip of the arc-shaped tooth 41, the limiting member 6 limits the movement rod 43, preventing the toothed block 42 from hitting the arc-shaped tooth 41 again under the force of the spring, thereby increasing the risk of connector breakage. In addition, by limiting the movement rod 43, the outer cylinder 51 is also limited. That is, at this time, the outer cylinder 51 separates the moving block from the inner wall of the turntable 3 through the connecting rod 52, thereby disconnecting the transmission between the first connecting block 1 and the second connecting block 2, so as to avoid connector breakage.

[0036] The limiting component 6 includes a base 61, which is disposed in the inner cavity of the connecting rod 10. The lower end of the base 61 is elastically connected to the inner cavity of the connecting rod 10 by a spring, which supports the base 61 upwards. Symmetrical sliders 65 are fixedly connected to both sides of the base 61. The inner wall of the connecting rod 10 has a groove for cooperating with the sliders 65. The cooperation between the groove and the sliders 65 can make the vertical movement of the base 61 in the inner cavity of the connecting rod 10 more stable, and at the same time prevent the base 61 from being excessively lifted by the spring. A limiting block 63 is fixedly connected to one side of the upper end of the base 61. The limiting block 63 has an inclined surface facing the second connecting block 2 on the side near the turntable 3. A button 62 is fixedly connected to the upper end of the base 61 away from the limiting block 63. The button 62 is L-shaped and consists of a horizontal part and a vertical part, wherein the lower end of the horizontal part is close to the limiting block 65. A symmetrical balance bar is fixedly connected to one side of the 3. The balance bar is slidably connected to the connecting rod 10. The width of the horizontal part is equal to the width of the connecting rod 10. That is, when the button 62 is pressed, the button 62 will not be pressed into the inner cavity of the connecting rod 10 due to the large pressing force. The length of the horizontal part is equal to the length of the base 61. When pressed, the button 62 and the base 61 are subjected to more even force, and there will be no jamming when moving down due to excessive force on one side. A driven block 64 is fixedly connected to the top wall of the inner cavity of the through groove 45. The driven block 64 is composed of a vertical block and a horizontal bar. The horizontal bar and the moving rod 43 are fixedly connected. The side of the vertical block near the limiting block 63 has an inclined surface facing the turntable 3. The distance between the symmetrical balance bars is greater than the width of the driven block 64. The width of the driven block 64 and the width of the limiting block 63 are both equal to the width of the inner cavity of the connecting rod 10.

[0037] When vibration or misalignment occurs and the moving rod 43 is pushed horizontally, the driven block 64 moves horizontally along with the moving rod 43 and continuously approaches the limiting block 63. During the contact between the tips of the toothed block 42 and the arc-shaped tooth 41, the inclined surface of the driven block 64 contacts the inclined surface of the limiting block 63, and continuously presses the limiting block 63 downward through the inclined surface, causing the limiting block 63 to move vertically downward continuously. The spring is compressed as a result, until the inclined surface of the driven block 64 passes over the inclined surface of the limiting block 63. At this time, the limiting block 63 moves vertically upward under the rebound action of the spring, thereby limiting the driven block 64, thus limiting the moving rod 43, and further limiting and fixing the position of the outer cylinder 51, so that the outer cylinder 51 will not be rebounded by the spring, thereby separating the moving block from the inner cavity side wall of the turntable 3, thereby cutting off the transmission from the first connecting block 1 to the second connecting block 2, thus avoiding the situation where the connector breaks due to continuous operation in a high-speed rotating and unstable environment.
