[0037] 1 and 2, the connection structure in this embodiment includes a first connection part 100 and a second connection part 200. Referring to FIG1, the first connection part 100 includes a connection member 110. Referring to FIG2 and FIG4, the second connection part 200 includes a clamping claw 210 and a driving claw 211.

[0038] The arm assembly 220, the clamping jaw 210 is connected to the driving arm assembly 220, and the driving arm assembly 220 can drive the opening and closing of the clamping jaw 210.

[0039] The clamping jaw 210 includes a first clamping arm 211 and a second clamping arm 212.

[0040] The accommodating cavity 230 is defined, and the accommodating cavity 230 can accommodate the connecting member 110. When the clamping jaws 210 are opened, the connecting member 110 can extend

[0041] The clamping jaws 210 are closed, and the connecting member 110 is locked in the accommodating cavity 230, thereby realizing the first connecting portion.

[0042] 100 is connected to the second connection part 200.

[0043] 3 to 5, in some embodiments, the driving arm assembly 220 includes a first arm 221, a second arm 222, a third arm 223 and a fourth arm 224. The two ends of the second arm 222 are rotatably connected to the first arm 221 and the first clamping arm 211, respectively.

[0044] The two ends of the arm 224 are rotatably connected to the third arm 223 and the second clamping arm 212 respectively. The first arm 221 and the third arm 223 are both connected to the machine

[0045] The first arm 221, the third arm 223 and the frame 250 are connected to each other in a rotational manner, and the connection between the first arm 221 and the third arm 223 and the frame 250 is overlapped to prevent the two from rotating.

[0046] The first arm 221 and the third arm 223 can rotate around the vertical axis. When the first arm 221 rotates around the vertical axis

[0047] When the second arm 222 is used, the motion is transmitted to the first clamping arm 211, so that the first clamping arm 211 rotates around the first clamping arm 211.

[0048] When the third arm 223 rotates around the vertical axis, the motion is transmitted to the second clamping arm 212 through the fourth arm 224.

[0049] 4 and 6, in the perspective of FIG6, if the second clamping arm 212 rotates around the second clamping arm rotation axis 242,

[0050] The first arm 221 rotates clockwise and the third arm 223 rotates counterclockwise, so that the first clamping arm 211 and the second clamping arm 212 will gradually

[0051] Referring to FIG. 4 and FIG. 7 , in the perspective of FIG. 7 , if the first arm 221 rotates counterclockwise and the third arm 223 rotates clockwise,

[0052] The first clamping arm 211 and the second clamping arm 212 will gradually open.

[0053] The rotation of the shaft can be achieved by setting two rotating motors to drive the first arm 221 and the third arm 223 to rotate respectively. Of course, the rotation of the two arms can also be achieved by other methods.

[0054] 3 and 5, in some embodiments, the first clamping arm shaft 241 and the second clamping arm shaft 242 are both fixedly connected to the frame 250. Fixing the rotating shafts of the first clamping arm 211 and the second clamping arm 212 can improve the stability of the first clamping arm 211.

[0055] The stability when rotating with the second clamping arm 212.

[0056] 3 to 5, in some embodiments, a toggle rod 260 and a drive rod 270 are further provided, and the drive rod 270 and the first

[0057] The first driving member 280 is a rotary motor, and the driving rod 270 is connected to the output shaft of the motor.

[0058] The first driving member 280 can drive the driving rod 270 to rotate around the horizontal axis. The toggle rod 260 is fixed on the driving rod 270 and can

[0059] The toggle lever 260 includes a first section 261 and a second section 262.

[0060] The two ends of the driving rod 270 are located at the two sides of the rotation center of the driving rod 260, that is, at the two ends of the driving rod 270.

[0061] The first arm 221 is provided with a first notch 2211, the third arm 223 is provided with a second notch 2231, and the third arm 224 is provided with a second notch 2231.

[0062] The first section 261 extends into the first notch 2211, and the second section 262 extends into the second notch 2231.

[0063] When the horizontal axis rotates, the first section 261 will drive the first arm 221 to rotate synchronously, and the second section 262 will drive the third arm 223 to rotate synchronously.

[0064] Since the first section 261 and the second section 262 are located on both sides of the rotation center of the toggle rod 260, the first

[0065] The rotation directions of the first arm 221 and the third arm 223 are opposite.

[0066] 6 to 7 and the above contents, if the toggle lever 260 toggles the first arm 221 to rotate clockwise, the third arm 223 to rotate counterclockwise,

[0067] If the toggle lever 260 toggles the first arm 221 to rotate counterclockwise and the third arm 223 to rotate clockwise, the clamping jaw 210 gradually opens. In this embodiment, by providing the toggle lever 260, a driving member can be used to synchronously drive the rotation of the first arm 221 and the third arm 223, which can not only reduce the number of components and simplify the overall structure, but also enable the first arm 221 and the third arm 223 to rotate synchronously.

[0068] The third arm 223 has better coordination when rotating. It is conceivable that the driving rod 270 can be removed and the toggle rod 260 can be

[0069] The rotation center is fixedly connected to the output shaft of the first driving member 280, and the first driving member 280 directly drives the toggle rod 260 to rotate around the horizontal axis, so as to further simplify the structure.

[0070] 3, 5 and 8, in some embodiments, the frame 250 is further provided with a stopper 251, the inside of the stopper 251 is hollow, and the driving rod 270 passes through the inside of the stopper 251. When the first driving member 280 drives the driving rod 270, the driving member 280 drives the driving rod 270.

[0071] The rod 270 will rotate inside the limiter 251, and the limiter 251 limits the driving rod 270 so that the rotation process

[0072] The size of the inner hollow part of the stopper 251 is slightly larger than the size of the driving rod 270 to ensure that the driving

[0073] The rod 270 rotates and also plays a limiting role.

[0074] Furthermore, in some embodiments, a limiting groove 252 is provided at the end of the limiting member 251, and the driving rod 270 passes through the limiting member.

[0075] After passing through the interior of 251, the end is exposed from the limiting groove 252. The connection between the toggle rod 260 and the driving rod 270 is located in the limiting groove.

[0076] 252, and the first section 261 and the second section 262 of the toggle rod 260 extend in opposite directions to the outside of the limiting groove 252.

[0077] When the first section 261 and the second section 262 rotate around the horizontal axis to a predetermined position, the first section 261 and the second section 262 will be aligned with the groove of the limiting groove 252.

[0078] Different areas of the wall contact and abut against each other, thereby limiting the rotation range of the toggle lever 260. Specifically, in the perspective of FIG. 8,

[0079] When the first section 261 contacts the groove wall on the left side of the limiting groove 252 and the second section 262 contacts the groove wall on the right side of the limiting groove 252,

[0080] The rotation range of the toggle rod 260 is limited, and the clamping jaw 210 is in a closed state; when the first section 261 and the right side of the limiting groove 252 are

[0081] When the second section 262 contacts the groove wall on the left side of the limiting groove 252, the rotation range of the toggle rod 260 is limited, and the clamp

[0082] The jaws 210 are in an open state. By providing the limit slots 252, the degree of opening and closing of the jaws 210 can be controlled to be preferably

[0083] range, so that the accommodating cavity 230 is not too small after it is opened, and the connecting member 110 cannot enter the accommodating cavity 230, or the accommodating cavity is not too small after it is closed.

[0084] 230 is too large to lock the connector 110 in the accommodating cavity 230.

[0085] 3, 5 and 8, in some embodiments, the frame 250 is further provided with two limit plates 253, the first arm 221

[0086] The third arm 223 is located in the space between the two limit plates 253. When the clamping jaws 210 are closed, the two limit plates 253 can

[0087] The first arm 221 and the third arm 223 can be limited respectively. Taking the first arm 221 as an example, during the closing process of the clamping jaw 210,

[0088] In the perspective of FIG6 , the first arm 221 rotates clockwise. When it rotates to the perspective of FIG7 , the clamping jaw 210 is closed.

[0089] The third arm 223 is blocked by the limiting plate 253, which inhibits it from continuing to rotate. The limiting state of the third arm 223 is similar to that of the first arm 221, so it will not be described in detail.

[0090] 6 and 7, in some embodiments, when the clamping jaw 210 is closed, the first arm 221 and the second arm 222 are collinear.

[0091] The third arm 223 and the fourth arm 224 are in the same line, and the driving arm assembly 220 is at the dead point.

[0092] 230, the connecting member 110 will pull the first clamping arm 211 and the second clamping arm 212 to the left, but due to the driving arm assembly

[0093] 220 is at the dead point position, and the external force acting on the clamping jaw 210 cannot change the state of the driving arm assembly 220.

[0094] As long as the clamping jaws 210 are closed, they are in a self-locking state, and only the first driving member 280 drives the first arm 221 and the third arm 223 to rotate.

[0095] In this embodiment, the clamping jaw 210 uses dead point self-locking to make the locking of the connecting member 110 more stable.

[0096] The connecting member 110 is not easily separated from the clamping jaw 210 .

[0097] 2, 3 and 9, in some embodiments, a guide sleeve 290 is also fixed to the frame 250.

[0098] 290 is located at the entrance of the accommodating chamber 230. The guide sleeve 290 is truncated and has a guide channel 291 inside.

[0099] 291 is slightly larger than the size of the connecting member 110. When the first connecting part 100 is connected to the second connecting part 200, the guide sleeve 290 can

[0100] The connecting member 110 can be guided so that it enters the accommodating cavity 230 formed by the clamping jaw 210 through the guide channel 291.

[0101] 290 can reduce the position deviation and make it easier for the connecting member 110 to enter the accommodating cavity 230.

[0102] In some embodiments, other forms of driving arm assembly 220 may also be used. For example, the driving arm assembly 220 includes a first arm, a second arm, a third arm, and a fourth arm. The two ends of the second arm are rotatably connected to the first arm and the first clamping arm, respectively. The two ends of the fourth arm are rotatably connected to the third arm and the second clamping arm, respectively. The first arm and the third arm may be moved in the horizontal direction. When the first arm moves, the first clamping arm may be driven to rotate around the vertical axis. When the third arm moves, the second clamping arm may be driven to rotate around the vertical axis, thereby realizing the opening and closing of the clamping jaws. Of course, in addition to the above methods, other conventional structures that can realize the opening and closing of the clamping jaws are also possible.

[0103] 1, 9 and 10, in some embodiments, the first connecting portion 100 further includes a rope winding drum 120 and a rope winding drum 121.

[0104] The cable drum 120 is connected to the cable drum driving member 130, and the cable drum can be driven by the cable drum driving member 130.

[0105] One end of the connecting rope 140 is fixedly connected to the rope winding drum 120, and the other end passes through the inner part of the conical member 150.

[0106] The channel is fixedly connected to the connecting member 110, and the connecting rope 140 can be wound around the rope drum 120. When the rope drum 120 rotates,

[0107] The connecting rope 140 can be retracted and released. The connecting member 110 is provided with a recessed portion (not shown in the figure) capable of accommodating the head of the conical member 150.

[0108] As shown in FIG. 1 ), when the connecting rope 140 is tightened, the connecting member 110 is sleeved on the outside of the head of the conical member 150 through the recessed portion, and the first connecting member 110 is

[0109] The connecting part 100 is rigidly connected to the second connecting part 200. The connecting rope 140 is released, and the connecting member 110 is separated from the conical member 150.

[0110] There is a certain gap between the first connection part 100 and the second connection part 200, and the two are flexibly connected. By retracting and releasing the connection rope 140, the connection state can be adjusted to adapt to different environmental requirements.

[0111] 11 to 13, in some embodiments, a catamaran is also provided, which includes a first hull unit 300 and a second hull unit 400. A first connecting portion 100 is provided on the first hull unit 300, and a second connecting portion 200 is provided on the second hull unit 400. The first hull unit 300 and the second hull unit 400 are connected as a whole through the above-mentioned connection structure. After being connected as one, the hull width increases, the deck area is larger, more cargo can be loaded, and the stability during navigation can be improved and the bumps can be reduced. Although a catamaran is provided in this embodiment, in fact, a larger number of hull units can be connected as one. A first connecting portion 100 can be provided at one end of each hull unit, and a second connecting portion 200 can be provided at the other end, and both ends of the hull unit are connected to other hull units. The first connecting portion 100 and / or the second connecting portion 200 provided on each hull unit can also be increased.

[0112] The number of parts is 200 to enhance the stability of the connection between the hull units.

[0113] 10 and 14, when the catamaran is used for rescue operations in a narrow channel, the connecting rope 140 may be

[0114] The first hull unit 300 is released to allow it to tilt at a certain angle, so that the hull unit can pass through a narrow area for rescue.

[0115] 11 to 13, in some embodiments, the first hull unit 300 is provided with a first guide member 310 extending outward horizontally, and the second hull unit 400 is provided with a second guide member 410 extending outward. The second guide member 410 defines a guide cavity 420, and the size of the guide cavity 420 is slightly larger than the first guide member 310. When the first hull unit 300 and the second hull unit 400 travel to a position close to each other, if the first guide member 310 partially enters the guide cavity 420, the second guide member 410

[0116] The first hull unit 300 is guided by limiting the position of the first guide member 310 so that the first guide member 310 gradually moves

[0117] All enter the guide cavity 420. The cooperation between the first guide member 310 and the second guide member 410 enables the first hull unit 300 to

[0118] The second hull unit 400 is easier to align and can be connected more quickly. Of course, the second hull unit 400 can also be directly connected to the second hull unit 400.

[0119] A groove matching the first guide member 310 is provided to limit the first guide member 310. The first guide member 310 may also be formed of other

[0120] The shape may be an arc shape or a polygon shape, as long as the width of the first guide member 310 in the direction away from the first hull unit 300 is

[0121] It can be gradually reduced. Of course, the shape of the guide cavity 420 needs to match the shape of the first guide member 310 .

[0122] With reference to all the accompanying drawings, taking the catamaran in FIG. 13 as an example, the connection process of the two hull units is described as follows:

[0123] In the initial state, the clamping jaws 210 are open. The first hull unit 300 and the second hull unit 400 gradually approach each other.

[0124] The guide member 310 partially enters the guide cavity 420 formed by the second guide member 410 for preliminary guidance. The two ships continue to approach, and the first

[0125] The guide member 310 gradually enters the guide cavity 420. At the same time, the guide sleeve 290 performs secondary guidance on the connecting member 110.

[0126] The first driving member 280 drives the driving rod 270 to move the connecting member 110 into the accommodating chamber 230 through the guide channel 291.

[0127] The toggle rod 260 connected to the driving rod 270 rotates around the horizontal axis. The first section 261 on the toggle rod 260

[0128] The first arm 221 is moved to rotate, and the second section 262 moves the third arm 223 to rotate, so that the first clamping arm 211 and the second clamping arm 213 are connected.

[0129] The arm 212 gradually closes. During the closing process, the limit slot 252 limits the rotation range of the first section 261 and the second section 262 of the toggle rod.

[0130] The two limiting plates 253 limit the first arm 221 and the third arm 223 respectively.
