Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of quick-connection devices, and in particular to a quick-connection device. Background Technology

[0002] In daily life and even in many industrial scenarios, it is necessary to frequently connect two parts together. For example, the connection between cables can use aviation plugs. However, this kind of connection between flexible wires can transmit power and electrical signals, but cannot transmit rigid force, that is, it cannot firmly connect the two parts together. If it is necessary to rigidly connect the two parts, it is generally necessary to use a flange and screws (bolts and nuts) to connect them.

[0003] In the existing technology, although the flange and screw (bolt and nut) connection method can ensure the connection strength, when applied to components that need to be frequently connected and disassembled, this connection method is difficult to install and disassemble, resulting in low efficiency of connection and disassembly.

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0044] The following is a reference appendix. Figure 1-15 A quick-connection device 100 according to an embodiment of the present invention is described.

[0045] like Figures 1-9 As shown, the quick-connection device 100 according to an embodiment of the present utility model is used to connect a first structural member and a second structural member. The quick-connection device 100 includes a first connecting member 10, a second connecting member 20, and a locking member 30.

[0046] The first connector 10 is adapted to connect to the first structural member and includes a first annular plate 11 extending along a first direction, with a first boss 12 on the outer peripheral surface of the first annular plate 11; the second connector 20 is adapted to connect to the second structural member, is arranged on one side of the first connector 10 in the first direction, and includes a second annular plate 21 sleeved on the outside of the first annular plate 11, with a second boss 22 and a clearance notch 23 arranged circumferentially on the inner peripheral surface of the second annular plate 21; the first annular plate 11 is rotatable relative to the second annular plate 21 between a positioning position and a snap-fit ​​position; in the positioning position, the first boss 12 and the clearance notch 23 are engaged. The notch 23 faces each other in the first direction. In the snap-fit ​​position, the first boss 12 is located on the side of the second boss 22 away from the first connector 10 and abuts against the second boss 22 in the first direction. The locking member 30 is provided on the second connector 20 and is movable between the locked position and the unlocked position in the first direction. In the locked position, the locking member 30 connects the first ring plate 11 and the second ring plate 21 so that the first ring plate 11 and the second ring plate 21 are relatively fixed in the circumferential direction. In the unlocked position, the locking member 30 is separated from the first connector 10, and the first ring plate 11 can rotate relative to the second ring plate 21.

[0047] It should be noted that in some specific examples, such as Figures 1-9 As shown, the first direction is the front-to-back direction. For example... Figures 1-3 As shown, the first connector 10 is fixedly connected to the first structural member, and the first structural member is located on the front side of the first connector 10. Figure 4 and Figure 5 As shown, the first connector 10 includes a first ring plate 11 extending in the front-back direction, and a first boss 12 is provided on the outer peripheral surface of the first ring plate 11. The first boss 12 extends in the front-back direction.

[0048] In some specific examples, such as Figure 6 and Figure 7 As shown, the second connector 20 is fixedly connected to the second structural member, and the second structural member is located on the rear side of the second connector 20. The second connector 20 includes a second ring plate 21, which is sleeved on the outside of the first ring plate 11. Further, a second boss 22 is formed on the inner circumferential surface of the second ring plate 21, which protrudes radially inward along the second ring plate 21. An avoidance notch 23 is formed in the circumferential direction of the second ring plate 21.

[0049] When installing the first connector 10 onto the second connector 20, first align the first boss 12 on the first ring plate 11 with the clearance notch 23 on the second ring plate 21 in the front-back direction. Then move the first connector 10 backward in the front-back direction so that the first boss 12 passes through the clearance notch 23 and the second ring plate 21 is fitted onto the outside of the first ring plate 11. At this time, the first boss 12 and the clearance notch 23 are positioned opposite the first ring plate 11 in the front-back direction.

[0050] Subsequently, the first ring plate 11 is rotated circumferentially, causing the first boss 12 to rotate to the rear side of the second boss 22 and abut against the second boss 22 in the front-rear direction. At this time, the first ring plate 11 is in the engaging position, thereby restricting the relative movement of the first connector 10 and the second connector 20 in the front-rear direction. In some specific examples, the rotation angle of the first ring plate 11 between the positioning position and the engaging position is 45°.

[0051] In some specific examples, such as Figure 8 and Figure 9 As shown, the quick-connect device 100 includes a locking member 30, which is disposed on the second connecting member 20 and can move relative to the second connecting member 20 in the front-back direction between a locked position and an unlocked position. When the locking member 30 is in the locked position, it effectively restricts the relative rotation between the first ring plate 11 and the second ring plate 21, thereby fixing the first connecting member 10 and the second connecting member 20 relative to each other in the circumferential direction. When the locking member 30 is in the unlocked position, it separates from the first connecting member 10, allowing the first ring plate 11 and the second ring plate 21 to rotate relative to each other, thus allowing the first connecting member 10 and the second connecting member 20 to rotate relative to each other.

[0052] In this embodiment, when installing the first connecting member 10 onto the second connecting member 20, the first ring plate 11 is first installed to the positioning position, and then the first ring plate 11 is rotated to the snap-fit ​​position, thereby restricting the relative movement of the first connecting member 10 and the second connecting member 20 in the front-back direction. Then, the locking member 30 is adjusted so that it moves in the front-back direction to the locking position, thereby effectively restricting the relative rotation between the first ring plate 11 and the second ring plate 21. Thus, the connection between the first structural member and the second structural member can be quickly completed.

[0053] When disassembling the first connector 10 from the second connector 20, first adjust the locking member 30 so that it moves to the unlocked position in the front-back direction, thereby separating the locking member 30 from the first connector 10. Then, rotate the first ring plate 11 to the positioning position so that the first boss 12 and the clearance notch 23 are aligned in the first direction. Then, move the first ring plate 11 forward to separate the first connector 10 from the second connector 20. This allows for the rapid disassembly of the first and second structural components.

[0054] According to the quick-connection device 100 of this utility model embodiment, by providing a first connecting member 10, a second connecting member 20 and a locking member 30, the first connecting member 10 is adapted to connect a first structural member and includes a first ring plate 11 extending in a first direction. The outer peripheral surface of the first ring plate 11 is provided with a first boss 12. The second connecting member 20 is adapted to connect a second structural member, is arranged on one side of the first connecting member 10 in the first direction, and includes a second ring plate 21 sleeved on the outside of the first ring plate 11. The inner peripheral surface of the second ring plate 21 is provided with a second boss 22 arranged in the circumferential direction and a clearance notch 23. The first ring plate 11 is rotatable relative to the second ring plate 21 between a positioning position and a locking position. In the positioning position, the first boss 12 and the clearance notch 23 are locked. The opening 23 faces each other in the first direction. In the snap-fit ​​position, the first boss 12 is located on the side of the second boss 22 away from the first connector 10 and abuts against the second boss 22 in the first direction. The locking member 30 is provided on the second connector 20 and can move between the locked position and the unlocked position along the first direction. In the locked position, the locking member 30 connects the first ring plate 11 and the second ring plate 21 so that the first ring plate 11 and the second ring plate 21 are relatively fixed in the circumferential direction. In the unlocked position, the locking member 30 is separated from the first connector 10, and the first ring plate 11 can rotate relative to the second ring plate 21, which facilitates the connection and disassembly of the first structural member and the second structural member, thereby effectively improving the efficiency of the connection and disassembly of the first structural member and the second structural member.

[0055] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, a locking groove 121 is formed on the first connector 10. The locking groove 121 extends along the first direction and the end of the locking groove 121 facing the locking member 30 is open. In the locked position, a part of the locking member 30 is engaged in the locking groove 121. In the unlocked position, the locking member 30 is separated from the locking groove 121 in the first direction.

[0056] In some specific examples, such as Figure 4 and Figure 5 As shown, the locking groove 121 on the first connecting member 10 extends in the front-rear direction, and further, the end of the locking groove 121 facing the locking member 30 is open. When the locking member 30 moves in the front-rear direction to the locked position, a part of the locking member 30 engages in the locking groove 121. Since the locking member 30 is connected to the second connecting member 20, it can effectively limit the relative rotation between the first ring plate 11 and the second ring plate 21, thereby effectively limiting the relative rotation between the first connecting member 10 and the second connecting member 20. When the locking member 30 moves in the front-rear direction to the unlocked position, the locking member 30 separates from the locking groove 121 in the front-rear direction, thereby releasing the circumferential restriction between the first connecting member 10 and the second connecting member 20.

[0057] In this embodiment, a locking groove 121 is formed on the first connector 10. The locking groove 121 extends along a first direction and is open at one end facing the locking member 30. In the locked position, a portion of the locking member 30 is engaged in the locking groove 121. In the unlocked position, the locking member 30 is separated from the locking groove 121 in the first direction. This can effectively improve the locking effect of the first connector 10 and the second connector 20 in the circumferential direction, thereby effectively improving the stability and reliability of the locking.

[0058] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the locking groove 121 is formed on the outer surface of the first boss 12 in the radial direction of the first ring plate 11 and extends through both sides of the first boss 12 in the first direction.

[0059] In some specific examples, such as Figure 4 and Figure 5 As shown, a portion of the outer surface of the first boss 12 in the radial direction is recessed inward along the radial direction of the first ring plate 11 to form a locking groove 121. Furthermore, the locking groove 121 extends through the front and rear surfaces of the first boss 12 in the front-rear direction. That is to say, the locking groove 121 is formed directly on the first boss 12 without the need for additional space, thereby effectively saving installation space.

[0060] In this embodiment, by forming the locking groove 121 on the outer surface of the first boss 12 in the radial direction of the first ring plate 11 and penetrating both sides of the first boss 12 in the first direction, space can be effectively saved, thereby effectively improving the space utilization rate of the first connector 10.

[0061] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, there are multiple first protrusions 12, which are arranged at intervals along the circumference of the first ring plate 11. There are also multiple second protrusions 22, clearance notches 23 and locking members 30, which correspond one-to-one with the multiple first protrusions 12.

[0062] For example, the number of first bosses 12 can be two, three, four, five, or more than six, as in some specific examples, such as Figure 4 and Figure 5 As shown, there are four first protrusions 12, which are arranged at intervals along the circumference of the first ring plate 11. Furthermore, the intervals between any two adjacent first protrusions 12 are the same. There are four second protrusions 22, four clearance notches 23, and four locking members 30, which correspond one-to-one with the multiple first protrusions 12.

[0063] In this embodiment, by setting the number of first protrusions 12 to multiple, the multiple first protrusions 12 are arranged at intervals along the circumference of the first ring plate 11. The number of second protrusions 22, clearance notches 23 and locking members 30 are also multiple, and they correspond one-to-one with the multiple first protrusions 12. This enables multiple points of engagement and locking, thereby effectively improving the structural stability and load-bearing capacity of the quick engagement device 100.

[0064] In one embodiment of this utility model, such as Figure 3 As shown, the quick engagement device 100 further includes a toggle member 40, which is disposed on the second connector 20 and is used to push the locking member 30 to move between the locked position and the unlocked position.

[0065] In some specific examples, such as Figure 3 As shown, the second connector 20 is provided with a toggle member 40. By adjusting the position of the toggle member 40, the locking member 30 can be moved in the front-back direction, thereby pushing the locking member 30 to move between the locked position and the unlocked position, which facilitates the adjustment of the position of the locking member 30 and effectively improves the convenience of operation.

[0066] In this embodiment, by providing a toggle member 40 in the quick engagement device 100, the toggle member 40 is provided on the second connector 20 and is used to push the locking member 30 to move between the locked position and the unlocked position, which can facilitate the adjustment of the position of the locking member 30, thereby effectively improving the convenience of operation.

[0067] In one embodiment of this utility model, such as Figure 10 and Figure 11 As shown, the actuating member 40 extends in a ring shape along the circumference of the second ring plate 21 and is rotatable relative to the second ring plate 21 in the circumference. A pushing surface 41 extending along the circumference of the actuating member 40 is formed on the actuating member 40. In the direction from one side to the other in the circumferential direction of the actuating member 40, the pushing surface 41 extends obliquely toward the first connecting member 10. The pushing surface 41 abuts and engages with the locking member 30 in the first direction. In the locked position, the locking member 30 abuts with the end of the pushing surface 41 near the first connecting member 10. In the unlocked position, the locking member 30 abuts with the end of the pushing surface 41 away from the first connecting member 10.

[0068] In some specific examples, such as Figure 10 and Figure 11 As shown, the actuating member 40 extends circumferentially along the second ring plate 21 in a ring structure. Further, the second ring plate 21 is sleeved on the outside of the actuating member 40, and the actuating member 40 is rotatable circumferentially relative to the second ring plate 21. Figure 10As shown, a groove 42 is formed on the outer peripheral surface of the actuating member 40, which is recessed inward along the radial direction of the actuating member 40. The side wall of the groove 42 facing the first connector 10 is formed as a pushing surface 41. The pushing surface 41 extends circumferentially along the actuating member 40. In the direction from back to front, the pushing surface 41 extends obliquely toward the first connector 10.

[0069] For example Figure 10 and Figure 11 As shown, when the locking member 30 is in the locked position, the locking member 30 abuts against the front end of the pushing surface 41 in the front-rear direction; when the locking member 30 is in the unlocked position, the locking member 30 abuts against the rear end of the pushing surface 41 in the front-rear direction; when the locking member 30 moves between the locked position and the unlocked position, the locking member 30 slides against the pushing surface 41.

[0070] In this embodiment, the actuating member 40 extends in a ring shape along the circumference of the second ring plate 21 and is rotatable relative to the second ring plate 21 in the circumference. A pushing surface 41 extending along the circumference of the actuating member 40 is formed on the actuating member 40. In the direction from one side of the actuating member 40 to the other side in the circumferential direction, the pushing surface 41 extends obliquely toward the first connecting member 10. The pushing surface 41 abuts and cooperates with the locking member 30 in the first direction. In the locked position, the locking member 30 abuts with the end of the pushing surface 41 near the first connecting member 10. In the unlocked position, the locking member 30 abuts with the end of the pushing surface 41 away from the first connecting member 10. This can effectively simplify the locking and unlocking process between the first connecting member 10 and the second connecting member 20, thereby effectively improving work efficiency.

[0071] In one embodiment of this utility model, such as Figure 6 , Figure 7 and Figure 12 As shown, the second connector 20 has a mounting groove 24 on the side opposite to the first connector 10. The mounting groove 24 extends in a ring shape along the circumference of the second ring plate 21. The actuating member 40 is rotatably disposed in the mounting groove 24, and a protruding actuating handle 43 is formed on the actuating member 40.

[0072] In some specific examples, such as Figure 6 and Figure 7 As shown, a mounting groove 24 extending in an annular shape along the circumference of the second ring plate 21 is formed in the second connector 20. The mounting groove 24 is located on the rear side of the second ring plate 21. The actuating member 40 is rotatably disposed in the mounting groove 24. Furthermore, the actuating member 40 is provided with an actuating handle 43, which can cause the actuating member 40 to rotate by actuating the handle 43. For example Figure 12 As shown, the toggle handle 43 and the toggle member 40 are detachably connected.

[0073] In some specific examples, such as Figure 6 and Figure 7 As shown, a baffle 211 extending in a ring shape along the circumference of the second ring plate 21 is formed on the rear edge of the inner circumferential surface of the second ring plate 21. The rear side of the baffle 211 can abut against the actuating member 40. Furthermore, a first guide slope 111 is formed at the rear end of the first ring plate 11, and the inner circumferential surface of the baffle 211 is formed as a second guide slope 2111. The first guide slope 111 and the second guide slope 2111 cooperate to facilitate the alignment of the first connecting member 10 and the second connecting member 20 in the front-rear direction.

[0074] In this embodiment, an mounting groove 24 is provided on the side of the second connector 20 opposite to the first connector 10. The mounting groove 24 extends in a ring shape along the circumference of the second ring plate 21. The actuating member 40 is rotatably disposed in the mounting groove 24, which can effectively improve the stability of the actuating member 40 when rotating. By providing a protruding actuating handle 43 on the actuating member 40, it is easy to rotate the actuating member 40, thereby effectively improving the convenience of operation.

[0075] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a through hole 212 is formed on the second ring plate 21. The through hole 212 extends circumferentially along the second ring plate 21 and passes through the side wall of the mounting groove 24 and the outer peripheral surface of the second ring plate 21 radially. The toggle handle 43 extends radially outward along the toggle member 40 and extends through the through hole 212 to the outside of the second ring plate 21.

[0076] In some specific examples, such as Figure 1 and Figure 2 As shown, one end of the toggle handle 43 is connected to the toggle member 40, and the other end of the toggle handle 43 extends through the through hole 212 to the outside of the second ring plate 21. The toggle handle 43 can move circumferentially along the second ring plate 21 in the through hole 212, thereby causing the toggle member 40 to rotate, and thus causing the locking member 30 to move between the locked position and the unlocked position.

[0077] In this embodiment, by forming a through hole 212 on the second ring plate 21, the through hole 212 extends circumferentially along the second ring plate 21 and passes radially through the side wall of the mounting groove 24 and the outer peripheral surface of the second ring plate 21. The toggle handle 43 extends radially outward along the toggle member 40 and extends through the through hole 212 to the outside of the second ring plate 21. This can effectively optimize the structural layout of the second connector 20 and the toggle member 40, thereby effectively saving space and improving the compactness of the quick-connect device 100.

[0078] In one embodiment of this utility model, such as Figure 13 and Figure 14As shown, the quick-connect device 100 also includes a pressure ring 50, which is disposed on the second connector 20 and located on the side of the actuating member 40 away from the first connector 10 in the first direction. The actuating member 40 is located between the bottom wall of the mounting groove 24 and the pressure ring 50.

[0079] In some specific examples, such as Figure 13 and Figure 14 As shown, the pressure ring 50 extends circumferentially along the second ring plate 21 in a ring structure and is located behind the second connecting member 20. The front end of the pressure ring 50 abuts against the rear end of the actuating member 40, that is, the actuating member 40 is located between the pressure ring 50 and the retaining rib 211. Furthermore, the pressure ring 50 and the second connecting member 20 are bolted together.

[0080] In this embodiment, by providing a pressure ring 50 in the quick-connect device 100, the pressure ring 50 is disposed on the second connector 20 and located on the side of the actuating member 40 away from the first connector 10 in the first direction. The actuating member 40 is located between the bottom wall of the mounting groove 24 and the pressure ring 50. This not only effectively improves the stability of the actuating member 40 when it rotates, but also effectively improves the structural strength and rigidity of the second connector 20, thereby effectively improving the reliability of the second connector 20.

[0081] In one embodiment of this utility model, such as Figure 15 As shown, the quick-engagement device 100 also includes an elastic element 60, which is connected to the locking element 30 and is configured to always push the locking element 30 against the pushing surface 41.

[0082] In some specific examples, the elastic element 60 is a compression spring, one end of which is connected to the pressure ring 50, and the other end of which is connected to the locking element 30. The compression spring can always push the locking element 30 against the pushing surface 41. During the process of the locking element 30 moving from the unlocked position to the locked position, the compression spring can push the locking element 30 forward; during the process of the locking element 30 moving from the locked position to the unlocked position, the pushing surface 41 can push the locking element 30 backward, thereby further compressing the compression spring.

[0083] In this embodiment, by providing an elastic element 60 in the quick engagement device 100, the elastic element 60 is connected to the locking element 30, and the elastic element 60 is configured to always push the locking element 30 against the pushing surface 41, which can ensure that the locking element 30 is always in contact with the pushing surface 41, thereby effectively avoiding the risk of accidental unlocking and thus effectively improving the reliability of the locking element 30.

[0084] In one embodiment of this utility model, such as Figure 8 and Figure 9As shown, the locking member 30 extends in a rod shape along the first direction, and a notch 31 is formed on the circumferential surface of the locking member 30. The side wall of the notch 31 facing the first connector 10 is an abutment wall 311, which abuts against the pushing surface 41.

[0085] In some specific examples, such as Figure 8 and Figure 9 As shown, the locking member 30 extends in a rod shape along the front-rear direction. The outer peripheral surface of the locking member 30 is recessed radially inward to form a notch 31. The rear sidewall of the notch 31 is formed as an abutment wall 311, which abuts against the pushing surface 41. Furthermore, the locking member 30 also has an opening groove 32 for mounting the elastic member 60, and a portion of the elastic member 60 is located in the opening groove 32.

[0086] Furthermore, a pin 33 is formed on the front end face of the locking member 30, extending in the front-rear direction. A socket 214 is provided on the second ring plate 21, with the pin 33 corresponding to each socket 214. When the locking member 30 is in the locked position, the pin 33 is located within the socket 214; when the locking member 30 is in the unlocked position, the pin 33 disengages from the socket 214.

[0087] In this embodiment, the locking member 30 extends into a rod shape along the first direction, and a notch 31 is formed on the circumferential surface of the locking member 30. The side wall of the notch 31 facing the first connector 10 is an abutment wall 311, which abuts against the pushing surface 41. This can effectively optimize the structural structure of the locking member 30, save the installation space of the locking member 30, and thus effectively improve the space utilization rate.

[0088] In one embodiment of this utility model, such as Figure 6 As shown, a guide groove 213 extending in the first direction is formed on the inner circumferential surface of the second ring plate 21, and the locking member 30 is movably disposed in the guide groove 213.

[0089] In some specific examples, such as Figure 6 As shown, a guide groove 213 extending in the front-rear direction is formed on the inner circumferential surface of the second ring plate 21. The guide groove 213 can provide a guide channel for the locking member 30. When the locking member 30 moves between the locked position and the unlocked position, the locking member 30 can move stably in the guide groove 213 in the front-rear direction.

[0090] In this embodiment, a guide groove 213 extending in the first direction is formed on the inner circumferential surface of the second ring plate 21, and the locking member 30 is movably disposed in the guide groove 213, which can further improve the stability of the locking member 30 when it moves in the first direction.

[0091] In one embodiment of this utility model, such as Figures 4-7As shown, the first connecting member 10 also includes a first flange plate 13, which is connected to the end of the first ring plate 11 opposite to the second connecting member 20. The second connecting member 20 also includes a second flange plate 25, which is connected to the end of the second ring plate 21 opposite to the first connecting member 10.

[0092] In some specific examples, such as Figure 4 and Figure 5 As shown, the first flange plate 13 is connected to the front side of the first ring plate 11, and the first flange plate 13 is provided with a plurality of first connecting holes 131 for connecting the first structural component. Figure 6 and Figure 7 As shown, the second flange plate 25 is connected to the rear side of the second ring plate 21, and the second flange plate 25 is provided with a plurality of second connection holes 251 for connecting the second structural component.

[0093] In this embodiment, by providing a first flange plate 13 in the first connecting member 10, the first flange plate 13 is connected to the end of the first ring plate 11 opposite to the second connecting member 20, and by providing a second flange plate 25 in the second connecting member 20, the second flange plate 25 is connected to the end of the second ring plate 21 opposite to the first connecting member 10, which can stably connect the first connecting member 10 to the first structural member and stably connect the second connecting member 20 to the second structural member, thereby effectively improving the reliability of the quick-connect device 100.
