[0045] As Figure 1 、 Figure 2 and Figure 3 shown, an embodiment of this application provides a forward and reverse winding and unwinding device 100. The forward and reverse winding and unwinding device 100 includes a main body 110, a transmission member 120, a check connection assembly 130, and a driving member 140.

[0046] Referring together to Figure 4 、 Figure 5 and Figure 6 wherein, the main body 110 has a receiving cavity 111 with openings at both ends, and a first check portion 112 is provided at one end of the main body 110. The transmission member 120 is rotatably disposed in the receiving cavity 111 about the axial direction, and a first clamping portion 121 is provided at one end of the transmission member 120 close to the first check portion 112.

[0047] The check connection component 130 includes a rotating member 131, a check member 132, and a connecting member 133. The rotating member 131 is rotatably disposed in the accommodation cavity 111 about the axial direction. The check member 132 and the connecting member 133 are both mounted on the rotating member 131. The check member 132 is provided with a first elastic arm 1321. A second check portion 13211 that cooperates with the first check portion 112 is provided at the circumferential edge of the first elastic arm 1321. The connecting member 133 is provided with a second elastic arm 1331. A second engaging portion 13311 that cooperates with the first engaging portion 121 is provided at the circumferential edge of the second elastic arm 1331, and a first protruding portion 13312 is provided. A second protruding portion 1311 is provided on the rotating member 131.

[0048] On one side of the driving member 140 facing the main body 110, a third protruding portion 141 and a fourth protruding portion 142 are provided. The third protruding portion 141 cooperates with the second protruding portion 1311, and the fourth protruding portion 142 cooperates with the first protruding portion 13312.

[0049] When the driving member 140 is rotated clockwise, the third protruding portion 141 abuts against the second protruding portion 1311, the fourth protruding portion 142 separates from the first protruding portion 13312, and the second engaging portion 13311 engages with the first engaging portion 121; when the driving member 140 is rotated counterclockwise, the third protruding portion 141 separates from the second protruding portion 1311, the fourth protruding portion 142 abuts against the first protruding portion 13312, and the second engaging portion 13311 separates from the first engaging portion 121.

[0050] In the forward and reverse winding and unwinding device 100 provided by the embodiment of the present application, during the use process, when it is necessary for the transmission member 120 to rotate clockwise, by rotating the driving member 140 in the clockwise direction, the entire check connection component 130 is driven to rotate clockwise synchronously with the driving member 140 under the abutting action of the third protruding portion 141 and the second protruding portion 1311. At this time, the fourth protruding portion 142 separates from the first protruding portion 13312, and the second engaging portion 13311 engages with the first engaging portion 121. Thus, the transmission member 120 is driven to rotate clockwise synchronously under the engaging action of the second engaging portion 13311 and the first engaging portion 121, thereby realizing the function of the transmission member 120 rotating clockwise. At this time, the second check portion 13211 engages with the first check portion 112 to prevent the entire check connection component 130, transmission member 120, and driving member 140 from rotating counterclockwise synchronously.

[0051] If it is necessary to cut off the transmission between the driving member 140 and the transmission member 120, by rotating the driving member 140 in the counterclockwise direction, the third protrusion 141 and the second protrusion 1311 change from being in contact with each other to being separated from each other, and the fourth protrusion 142 and the first protrusion 13312 change from being separated from each other to being in contact with each other, so that under the abutting action of the fourth protrusion 142 and the first protrusion 13312, the second engaging portion 13311 and the first engaging portion 121 are separated, and then the transmission member 120 can rotate freely in the counterclockwise direction, realizing the function of cutting off the transmission between the driving member 140 and the transmission member 120.

[0052] When it is necessary to rotate the transmission member 120 clockwise again, by rotating the driving member 140 in the clockwise direction, the third protrusion 141 and the second protrusion 1311 change from being separated from each other to being in contact with each other, and the fourth protrusion 142 and the first protrusion 13312 change from being in contact with each other to being separated from each other, so that the second engaging portion 13311 and the first engaging portion 121 are re-engaged, and thus the transmission member 120 is driven to rotate synchronously clockwise under the engaging action of the second engaging portion 13311 and the first engaging portion 121, and then the function of rotating the transmission member 120 clockwise again is realized. That is, by changing the rotation direction of the driving member 140, the working state of the transmission member 120 can be switched, and the operation is simple and convenient, avoiding the technical problem of difficult operation caused by pulling up the knob in the prior art.

[0053] If Figure 4 、 Figure 8 and Figure 9 As shown in, in an embodiment of the present application, optionally, a fifth protrusion 143 is provided on one side of the driving member 140 facing the main body 110, and the fifth protrusion 143 cooperates with a side of the first protrusion 13312 away from the fourth protrusion 142.

[0054] When the driving member 140 is rotated clockwise, the fifth protrusion 143 abuts against a side of the first protrusion 13312 away from the fourth protrusion 142; when the driving member 140 is rotated counterclockwise, the fifth protrusion 143 is separated from a side of the first protrusion 13312 away from the fourth protrusion 142.

[0055] In this embodiment, by providing a fifth protrusion 143 on the side of the driving member 140 facing the main body 110, and the fifth protrusion 143 cooperating with the side of the first protrusion 13312 away from the fourth protrusion 142, during the process of rotating the driving member 140 in the clockwise direction to make the transmission member 120 rotate clockwise, the fifth protrusion 143 and the side of the first protrusion 13312 away from the fourth protrusion 142 are always kept in contact, so that the second engaging portion 13311 and the first engaging portion 121 are always kept engaged, ensuring the engaging stability between the second engaging portion 13311 and the first engaging portion 121.

[0056] Meanwhile, during the process of rotating the driving member 140 in the counterclockwise direction to cut off the transmission between the driving member 140 and the transmission member 120, the fifth protrusion 143 and the side of the first protrusion 13312 away from the fourth protrusion 142 change from being in contact with each other to being separated from each other, so that the second engaging portion 13311 can be separated from the first engaging portion 121 under the abutting action of the fourth protrusion 142 and the first protrusion 13312, and further the transmission member 120 can rotate freely in the counterclockwise direction, realizing the function of cutting off the transmission between the driving member 140 and the transmission member 120.

[0057] During the process of rotating the driving member 140 in the clockwise direction again to make the transmission member 120 rotate clockwise, the fourth protrusion 142 and the first protrusion 13312 change from being in contact with each other to being separated from each other, and the fifth protrusion 143 and the side of the first protrusion 13312 away from the fourth protrusion 142 change from being separated from each other to being in contact with each other, so that the second engaging portion 13311 and the first engaging portion 121 are always kept engaged, ensuring the engaging stability between the second engaging portion 13311 and the first engaging portion 121.

[0058] As Figure 5 、 Figure 7 and Figure 9 shown, in an embodiment of the present application, optionally, the check connection assembly 130 further includes an elastic member 134. A first mounting post 1312 is provided on the rotating member 131. The check member 132 includes a first mounting portion 1322 and the first elastic arm 1321. The first elastic arm 1321 is connected to the outer circumference of the first mounting portion 1322. Both the first mounting portion 1322 and the elastic member 134 are sleeved on the first mounting post 1312, and the elastic member 134 is respectively connected to the rotating member 131 and the first elastic arm 1321.

[0059] In this embodiment, the first elastic arm 1321 is connected to the outer circumference of the first mounting portion 1322. By sleeving both the first mounting portion 1322 and the elastic member 134 on the first mounting post 1312 of the rotating member 131, and connecting the elastic member 134 to the rotating member 131 and the first elastic arm 1321 respectively, the first elastic arm 1321 is urged to always abut against the first check portion 112 under the elastic force of the elastic member 134, so that the second check portion 13211 and the first check portion 112 are always engaged, thereby preventing the check connection assembly 130, the transmission member 120, and the driving member 140 from rotating counterclockwise synchronously as a whole when the transmission member 120 needs to rotate clockwise.

[0060] Exemplarily, the elastic member 134 can be a torsion spring, and the first elastic arm 1321 and the first mounting portion 1322 can be integrally injection-molded.

[0061] As Figure 5 and Figure 9 As shown in the figure, in an embodiment of the present application, optionally, the connecting member 133 includes a second mounting portion 1332 and the second elastic arm 1331. The second elastic arm 1331 is connected to the outer circumference of the second mounting portion 1332. A second mounting post 1313 is provided on the rotating member 131, and the second mounting portion 1332 is sleeved on the second mounting post 1313.

[0062] In this embodiment, the second elastic arm 1331 is connected to the outer circumference of the second mounting portion 1332. By providing a second mounting post 1313 on the rotating member 131 and sleeving the second mounting portion 1332 on the second mounting post 1313, the second elastic arm 1331 and the second mounting portion 1332 can rotate synchronously around the axis of the second mounting post 1313. Thus, when the driving member 140 is rotated clockwise, the second engaging portion 13311 can be engaged with the first engaging portion 121 under the separation action of the fourth protrusion 142 and the first protrusion 13312, and when the driving member 140 is rotated counterclockwise, the second engaging portion 13311 can be separated from the first engaging portion 121 under the abutting action of the fourth protrusion 142 and the first protrusion 13312.

[0063] Exemplarily, the second elastic arm 1331 and the second mounting portion 1332 can be integrally injection-molded.

[0064] In an embodiment of the present application, optionally, the check connection assembly 130 further includes a cover body (not shown in the figure). The cover body is mounted on the rotating member 131, and a sixth protrusion is provided on the inner circumference of the cover body. The sixth protrusion cooperates with the side of the first elastic arm 1321 away from the second check portion 13211.

[0065] In this embodiment, by mounting the cover on the rotating member 131 and providing a sixth convex portion on the inner circumferential direction of the cover to cooperate with the side of the first elastic arm 1321 away from the second check portion 13211, under the abutting action between the sixth convex portion and the side of the first elastic arm 1321 away from the second check portion 13211, the first elastic arm 1321 is driven to always abut against the first check portion 112, so that the second check portion 13211 and the first check portion 112 are always in snap connection, thereby avoiding the overall synchronous counterclockwise rotation of the check connection assembly 130, the transmission member 120, and the driving member 140 when the transmission member 120 needs to rotate clockwise.

[0066] As Figure 3 , Figure 4 and Figure 5 shown, in the above embodiment of the present application, optionally, the forward and reverse winding and unwinding device 100 further includes a fastener 150. A connecting column 144 is provided on the side of the driving member 140 facing the main body 110. The fifth convex portion 143 is connected to the outer circumferential direction of the connecting column 144. The connecting column 144 is provided with a connecting hole 1441. A stepped hole 122 is provided at one end of the transmission member 120 away from the first engaging portion 121. The fastener 150 sequentially passes through the stepped hole 122 and the connecting hole 1441.

[0067] In this embodiment, by providing a connecting column 144 on the side of the driving member 140 facing the main body 110, the connecting column 144 is provided with a connecting hole 1441, and a stepped hole 122 is provided at one end of the transmission member 120 away from the first engaging portion 121, so that the fastener 150 can sequentially pass through the stepped hole 122 and the connecting hole 1441, thereby fixedly connecting the transmission member 120 and the driving member 140 and enabling them to rotate relative to each other, and further avoiding the transmission member 120 from disengaging from the accommodation cavity 111 and the driving member 140 from disengaging from the main body 110, ensuring the use stability and reliability of the forward and reverse winding and unwinding device 100.

[0068] Exemplarily, the fastener 150 can be a fastening screw, the connecting hole 1441 can be a threaded hole matching the fastening screw, and the connection mode between the fifth convex portion 143 and the connecting column 144 can be integrally injection molded.

[0069] As Figure 10 and Figure 11As shown, in any of the above embodiments of the present application, optionally, the transmission member 120 includes a shaft body 123 and disc bodies 124 disposed at both ends of the shaft body 123. The diameter of the disc body 124 is greater than that of the shaft body 123. The shaft body 123 is respectively provided with a first wire hole 1231 and a second wire hole 1232 along a direction perpendicular to the axis of the shaft body 123. The main body 110 is provided with a third wire hole 113 and a fourth wire hole 114. The third wire hole 113 is correspondingly disposed opposite to the first wire hole 1231, and the fourth wire hole 114 is correspondingly disposed opposite to the second wire hole 1232.

[0070] In this embodiment, the transmission member 120 includes a shaft body 123 and disc bodies 124 disposed at both ends of the shaft body 123, such that the transmission member 120 is a wire wheel for winding a wire, so that the forward and reverse wire winding and unwinding device 100 is a wire winding and unwinding device. One end of the wire rope can sequentially pass through the third wire hole 113 and the first wire hole 1231 and be knotted and fixed inside the wire wheel, and the other end of the wire rope can sequentially pass through the fourth wire hole 114 and the second wire hole 1232 and be knotted and fixed inside the wire wheel.

[0071] During use, when tightening the wire rope, by rotating the driving member 140 in the clockwise direction, the entire check connection assembly 130 is driven to rotate synchronously with the driving member 140 in the clockwise direction under the abutting action between the third protrusion 141 and the second protrusion 1311. At this time, the fourth protrusion 142 is separated from the first protrusion 13312, and the second engaging portion 13311 is engaged with the first engaging portion 121. Thus, the wire wheel is driven to rotate synchronously in the clockwise direction under the engaging action between the second engaging portion 13311 and the first engaging portion 121, thereby realizing the function of tightening the wire rope. At this time, the second check portion 13211 is engaged with the first check portion 112 to prevent the entire check connection assembly 130, the transmission member 120, and the driving member 140 from rotating synchronously in the counterclockwise direction and causing the wire rope to loosen.

[0072] If it is necessary to loosen the wire rope, by rotating the driving member 140 in the counterclockwise direction, the third protrusion 141 and the second protrusion 1311 are changed from abutting against each other to separating from each other, and the fourth protrusion 142 and the first protrusion 13312 are changed from separating from each other to abutting against each other. Under the abutting action between the fourth protrusion 142 and the first protrusion 13312, the second engaging portion 13311 is separated from the first engaging portion 121, and further the wire wheel can freely rotate in the counterclockwise direction to realize the function of loosening the wire rope.

[0073] When the wire rope needs to be tightened again, by rotating the driving member 140 in the clockwise direction, the third convex portion 141 and the second convex portion 1311 change from being separated from each other to being in contact with each other, and the fourth convex portion 142 and the first convex portion 13312 change from being in contact with each other to being separated from each other, so that the second engaging portion 13311 and the first engaging portion 121 are re-engaged. Thus, under the engaging action of the second engaging portion 13311 and the first engaging portion 121, the wire wheel is driven to rotate synchronously in the clockwise direction, thereby realizing the function of tightening the wire rope again. That is, by changing the rotation direction of the driving member 140, the rotation of the wire rope can be tightened or loosened, and the operation is simple and convenient, avoiding the technical problem of difficult operation caused by pulling up the knob in the prior art.

[0077] In this embodiment, by providing a gear transmission portion at one end of the transmission member 120 away from the first engaging portion 121, during use, when it is necessary to transmit the power between the gear transmission portion and other articles, by rotating the driving member 140 in the clockwise direction, the transmission member 120 is driven to rotate synchronously in the clockwise direction, thereby realizing the function of transmitting the power between the gear transmission portion and other articles.

[0078] When it is necessary to cut off the power between the gear transmission part and other items, rotate the driving part 140 counterclockwise to separate the second clamping part 13311 from the first clamping part 121, so that the transmission part 120 can rotate freely in the counterclockwise direction, thereby realizing the function of cutting off the power between the gear transmission part and other items.

[0079] When it is necessary to transmit the power between the gear transmission part and other items again, rotate the driving part 140 clockwise to drive the transmission part 120 to rotate synchronously clockwise, thereby realizing the function of transmitting the power between the gear transmission part and other items again. That is, by changing the rotation direction of the driving part 140, the power between the gear transmission part and other items can be transmitted or cut off, and the operation is simple and convenient.

[0080] In any of the above embodiments of the present application, optionally, a shaft transmission part (not shown in the figure) is provided at one end of the transmission part 120 away from the first clamping part 121.

[0081] In this embodiment, by providing a shaft transmission part at one end of the transmission part 120 away from the first clamping part 121, during use, when it is necessary to transmit the power between the shaft transmission part and other items, rotate the driving part 140 clockwise to drive the transmission part 120 to rotate synchronously clockwise, thereby realizing the function of transmitting the power between the shaft transmission part and other items.

[0082] When it is necessary to cut off the power between the shaft transmission part and other items, rotate the driving part 140 counterclockwise to separate the second clamping part 13311 from the first clamping part 121, so that the transmission part 120 can rotate freely in the counterclockwise direction, thereby realizing the function of cutting off the power between the shaft transmission part and other items.

[0083] When it is necessary to transmit the power between the shaft transmission part and other items again, rotate the driving part 140 clockwise to drive the transmission part 120 to rotate synchronously clockwise, thereby realizing the function of transmitting the power between the shaft transmission part and other items again. That is, by changing the rotation direction of the driving part 140, the power between the shaft transmission part and other items can be transmitted or cut off, and the operation is simple and convenient.
