[0025] First embodiment

[0026] Figure 1 A stereoscopic diagram of two connectors 100 provided according to the first embodiment of the utility model connected together is shown. Each connector 100 is connected to a connecting rope 3 respectively. The connecting rope 3 is connected to a floating body, for example. Through the connection of the two connectors 100, the two connecting ropes 3 connected to the two connectors 100 are connected together, and the two floating bodies connected to the two connecting ropes 3 can be connected together. Of course, the application scope of the connector 100 provided in the embodiment of the utility model is not limited to floating devices, and it can be applied to any suitable product.

[0027] See also Figure 1, the two connectors 100 respectively have a rotation axis XX, and the two connectors 100 connected together can rotate relative to each other around the rotation axis XX to switch between a locked state and an unlocked state. In the locked state, the two connectors 100 cannot be separated from each other along the direction of the rotation axis XX. In the unlocked state, the two connectors 100 can be separated from each other along the direction of the rotation axis XX. In some embodiments, the two connectors 100 connected together are generally shuttle-shaped, and the rotation axis XX can also be referred to as the longitudinal axis of each connector 100. Of course, in some alternative embodiments, the two connectors 100 connected together can also be other shapes.

[0028] Figure 2 Shows Figure 1 The two connectors 100 are shown in a perspective view separated from each other. When the two connectors 100 are separated from each other, the two connecting ropes 3 connected by the two connectors 100 are separated from each other, and then the two floating bodies connected with the two connecting ropes 3 are also separated from each other.

[0029] In some embodiments, each connector 100 includes a flat head end 1A and a round head end 1B, and the flat head end 1A and the round head end 1B can be transitioned through a step portion 1C. The flat head end 1A, for example, includes two surfaces 11A and 21A that are away from each other. In some embodiments, the surface 11A and the surface 21A can both be parallel to the rotation axis XX. In some embodiments, the surface 11A and the surface 21A can be tilted relative to the rotation axis XX, respectively. Of course, the implementation of the flat head end 1A is not limited to the above examples. The connecting rope 3 extends outward from the flat head end 1A. The round head end 1B of one connector 100 is used to be locked together with the round head end 1B of another connector 100 by relative rotation. The user's hands can easily pinch the flat head ends 1A of the two connectors 100. More specifically, the user's fingers pinch the surfaces 11A and 21A of the flat head end 1A to make the round head ends 1B of the two connectors rotate relative to each other. It should be noted that the cross-sectional shape of the round head end 1B described above is not limited to a strict circle. It can be understood that in some alternative embodiments, the structure of each connector 100 can also have other implementations and is not limited to the above examples.

[0030] Figures 3 to 6The exploded view of the connector 100 from multiple perspectives is shown. The connector 100 includes a first shell 1 and a second shell 2. In the present embodiment, the first shell 1 and the second shell 2 are fixed together by a fastener 4 after being docked together. A receiving cavity 10 is formed between the docked first shell 1 and the second shell 2. The connector 100 also includes a through hole 101, which is located at a first end of the connector 100 and is connected to the receiving cavity 10. The center line of the through hole 101 substantially coincides with the rotation axis XX, for example. The connecting rope 3 is connected to the connector 100 in the receiving cavity 10 and leaves the receiving cavity 10 through the through hole 101.

[0031] See also Figure 5 In some embodiments, one end 31 of the connecting rope 3 is fixed in the accommodating cavity 10 to hide the connection structure between the connecting rope 3 and the connector 100. More specifically, a positioning member 24 for engaging with the connecting rope 3 is provided in the accommodating cavity 10, one end of the connecting rope 3 can be wound around the positioning member 24, and the other end of the connecting rope 3 (not shown) can leave the accommodating cavity 10 through the through hole 101. In some alternative embodiments, the middle part of the connecting rope 3 can be wound around the positioning member 24, and both ends of the connecting rope 3 can leave the accommodating cavity 10 through the through hole 101.

[0032] See also Figure 5 and Figure 6 In this embodiment, the positioning member 24 extends from the second shell 2 toward the first shell 1, for example, along a direction perpendicular to the rotation axis XX. In some embodiments, the positioning member 24 may also have a center hole 240. A mounting hole 104 may be provided at a position of the first shell 1 opposite to the center hole 240. The fastener 4 passes through the mounting hole 104 and is connected to the center hole 240 of the positioning member 24. The fastener 4 strengthens the structural strength of the positioning member 24 while connecting the first shell 1 and the second shell 2 together. The fastener 4 may be, for example, a screw. In some alternative embodiments, the positioning member 24 may extend from the first shell 1 toward the second shell 2, and the mounting hole for installing the fastener 4 is correspondingly provided on the second shell 2.

[0033] See also Figure 5, the first end 31 of the connecting rope 3 is wound around the positioning member 24, and a limiting member 311 is provided at the end of the first end 31 of the connecting rope 3, and the limiting member 311 is located in the accommodating chamber 10. The limiting member 311 is, for example, spherical or in other suitable shapes, and the limiting member 311 may be a component different from the connecting rope 3. A channel 242 is formed between the wall of the accommodating chamber 10 and the positioning member 24 for the connecting rope 3 to pass through, and the size of the channel 242 is designed to not allow the limiting member 311 to pass through. In this embodiment, the channel 242 described above is formed between the positioning member 24 and the arc-shaped protrusion 2211 (the arc-shaped protrusion 2211 is described below). When the connecting rope 3 located outside the connector 100 is subjected to tension, the limiting member 311 is stuck in the channel 242, so that the first end 31 of the connecting rope 3 will not be detached from the connector 100. Of course, in some embodiments, the size of the limiter 311 can be further designed to prevent it from passing through the through hole 101 . Once the limiter 311 accidentally passes through the channel 242 , the limiter 311 can be stuck in the through hole 101 .

[0034] Of course, in some alternative embodiments, the first end 31 of the connecting rope 3 may not form the stopper 311 by adding additional components, but directly form the stopper 311 by tying a knot on the first end 31 of the connecting rope 3. Alternatively, in some alternative embodiments, the first end 31 of the connecting rope 3 may not be provided with the stopper 311, but may be directly tied to the positioning member 24. Alternatively, in some alternative embodiments, the first end 31 of the connecting rope 3 may not be connected to the positioning member 24, but the first end 31 of the connecting rope 3 may be limited from leaving the connector 100 by the cooperation of the stopper 311 and the through hole 101.

[0035] See also Figure 3 and Figure 4 The first housing 1 has a docking surface 131 and a docking surface 132, and the docking surface 131 and the docking surface 132 are located on both sides of the rotation axis XX of the connector 100. The docking surface 131 and the second docking surface 132 can be symmetrical with respect to the rotation axis XX. In some embodiments, the docking surface 131 and the second docking surface 132 are substantially on the same plane, and the rotation axis XX is also located on the same plane. The first housing 1 is, for example, an integrally formed symmetrical structure.

[0036] See also Figure 5 and Figure 6 The second housing 2 has a docking surface 231 and a docking surface 232, and the docking surface 231 and the docking surface 232 are located on both sides of the rotation axis XX. The docking surface 231 and the docking surface 232 can be symmetrical with respect to the rotation axis XX. In some embodiments, the docking surface 231 and the docking surface 232 are substantially on the same plane, and the rotation axis XX is also located on the same plane. The second housing 2 is, for example, an integrally formed symmetrical structure.

[0037] See also Figures 7 to 9 When the first shell 1 and the second shell 2 are butted together, the butt joint surface 131 of the first shell 1 and the butt joint surface 231 of the second shell 2 abut against each other, and the butt joint surface 132 of the first shell 1 and the butt joint surface 232 of the second shell 2 abut against each other.

[0038] See also Figures 3 to 6 The first shell 1 has a concave portion 133 disposed on the butt joint surface 131 and the butt joint surface 132, and the second shell 2 has a convex portion 233 disposed on the butt joint surface 231 and the butt joint surface 232. When the first shell 1 and the second shell 2 are butt jointed, the convex portion 233 is embedded in the concave portion 133, so that the butt joint surfaces of the first shell 1 and the second shell 2 are matched with each other, which can increase the firmness of the combination of the two.

[0039] In this embodiment, the recess 133 extends along the docking surface 131 and the docking surface 132 of the first shell 1. A portion of the recess 133 is formed by the step portion 1331, and a portion is formed by the groove 1332. Of course, in some alternative embodiments, the recess 133 can be formed entirely by the step portion or entirely by the groove. The convex portion 233 includes a convex strip extending along the docking surface 231 and the docking surface 232 of the second shell 2. At least a portion of the convex strip may also be provided with a convex rib 234, which can better abut against the wall of the recess 133.

[0040] Of course, in some alternative embodiments, the recess 133 and the convex strip 233 may have other implementations. For example, the positions of the recess 133 and the convex strip 233 on the first shell 1 and the second shell 2 may be interchanged. Alternatively, the recess 133 and the convex strip 233 may also adopt other structures (as described in the second embodiment below).

[0041] Continue to see Figures 3 to 6 , the first shell 1 includes a first end 11 and a second end 12. The second shell 2 includes a first end 21 and a second end 22. The first end 11 of the first shell 1 and the first end 21 of the second shell 2 both correspond to the flat head end 1A of the connector 100, which can also be referred to as the first end of the connector 100. The surface 11A is located on the first shell 1, and the surface 21A is located on the second shell 2. The second end 12 of the first shell 1 and the second end 22 of the second shell 2 both correspond to the round head end 1B of the connector 100, which can also be referred to as the second end of the connector 100. The first end 11 of the first shell 1 has a half hole, and the first end 21 of the second shell 2 also has a half hole, and the half hole of the first end 11 and the half hole of the first end 21 together form a through hole 101.

[0042] A portion of the end surface 121 of the second end 12 of the first housing 1 is provided with an outwardly extending clamping arm 14. The clamping arm 14 generally extends toward the outside of the end surface 121 in a direction parallel to the rotation axis XX. Alternatively, the clamping arm 14 is inclined at a small angle toward the direction close to the rotation axis XX while extending toward the outside of the end surface 121. A protruding finger 15 is provided at the end of the clamping arm 14 (the end away from the end surface 121).

[0043] In this embodiment, the clamping arm 14 extends a long distance in the direction around the rotation axis XX, and the clamping arm 14 has a certain thickness in the direction perpendicular to the rotation axis XX. The inner wall 141 of the clamping arm 14 is generally an arc surface, extending around the rotation axis XX. The protruding finger 15 extends radially inward from the inner wall 141 of the clamping arm 14. That is, the extending direction of the protruding finger 15 is generally perpendicular to the rotation axis XX.

[0044] Of course, in some alternative embodiments, the clamping arm 14 and the protruding finger 15 may have other implementations. For example, the protruding finger 15 extends from the end of the clamping arm 14 in the direction around the rotation axis XX, that is, the protruding finger 15 extends from the end of the clamping arm 14 along the circumferential direction. In this case, the protruding finger 15 may not protrude radially inward relative to the inner wall 141 of the clamping arm 14.

[0045] See also Figures 7 to 9 1 and 2. The connector 100 is a stereoscopic view of different viewing angles shown in FIG. 1. In some embodiments, when the first housing 1 and the second housing 2 are docked together, the end face 221 of the second end 22 of the second housing 2 is aligned with the end face 121 of the first housing 1. The outer peripheral wall of the second end 22 of the second housing 2 includes an arcuate wall 2201, and the arcuate wall 2201 extends around the rotation axis XX. A portion of the arcuate wall 2201 is provided with a radially outwardly extending card platform 224. The card platform 224 extends a certain length around the rotation axis XX.

[0046] See also Figures 10 to 12 , showing the connection process of two connectors 100. Fig.10 Before connecting two connectors 100, firstly, the round head ends 1B of the two connectors 100 are opposite to each other and the rotation axis XX of the two connectors 100 are overlapped, and the protruding fingers 14 of each connector 100 are staggered with the clamping platform 224 of the other connector 100 in the circumferential direction. Then, the two connectors 100 are moved along the direction of the rotation axis XX, and the protruding fingers 14 and the clamping platform 224 staggered in the circumferential direction will not affect the mutual approach of the two connectors 100. Fig.11, the two connectors 100 can be moved to a position where the end faces of their second ends are in contact with each other. When the end face 121 of the first shell 1 of the connector 100 and the end face 221 of the second shell 2 are flush, the end face of the second end of the connector 100 corresponds to the end face of the round head end 1B, specifically including the end face 121 of the first shell and the end face 221 of the second shell 2. At this time, the protruding finger 14 of each connector 100 and the clamping base 224 of another connector 100 are just offset in the direction of the rotation axis XX. Afterwards, the two connectors 100 can be relatively rotated around the rotation axis XX so that the protruding finger 14 of each connector is clamped with the clamping base 224 of another connector, as shown in FIG. Fig.12 At this time, the two connectors 100 cannot move away from each other along the direction of the rotation axis XX.

[0047] Of course, when it is necessary to separate the two connectors 100, Fig.12 The two connectors 100 shown in the figure rotate relative to each other around the rotation axis XX. Fig.11 In the state shown, the two connectors 100 can be pulled apart along the direction of the rotation axis XX.

[0048] See also Figures 7 to 9 The outer peripheral wall of the second end 22 of the second housing 2 is provided with a recess 220, which is used to accommodate the clamping arm 14 of another connector 100. The wall body of the recess 220 includes the above-mentioned arc-shaped wall 2201, the side wall 2203 and the two end walls 2202. The two end walls 2202 are located at the circumferential ends of the arc-shaped wall 2201, and are respectively the first end wall 22021 and the second end wall 22022. The side wall 2203 is away from the end surface 221 of the second housing 21. The side wall 2203 is formed, for example, on a side wall surface of the step portion 1C.

[0049] The card platform 224 is located in the recess 220. A notch 2204 is formed between the card platform 224 and the first end wall 22021, and the notch 2204 can guide the clamping arm 14 to extend into the recess 220. In some embodiments, the card platform 224 is connected to the second end wall 22022, and the recess 220 is generally L-shaped. The space between the side wall 2203 and the card platform 224 forms a guide channel 2206 for guiding the protruding finger 15 to slide. The cooperation between the two end walls 2202 and the clamping arm 14 (more specifically, the protruding finger 15 on the clamping arm 14) can be used to limit the relative rotation range of the two connectors 100.

[0050] See also Figure 7, a limiting protrusion 225 is provided on the arc wall 2201. The limiting protrusion 225 is more specifically located in the guide channel 2206. That is, the limiting protrusion 225 is provided on the wall of the guide channel 2206. The limiting protrusion 225 is, for example, close to the second end wall 22022. A limiting recess 152 is provided on the protruding finger 15. When the clamping arms 14 of the two connectors 100 are clamped with the corresponding clamping platform 224, the two connectors 100 are further locked by clamping the limiting protrusion 152 on each protruding finger 15 with the corresponding limiting protrusion 225, thereby preventing the two connectors 100 from unexpected relative rotation.

[0051] The limiting protrusion 225 is, for example, a rib extending in a direction parallel to the rotation axis XX. The limiting protrusion 225 is located between the side wall 2203 and the card table 224. The shape of the limiting recess 152 matches the shape of the limiting protrusion 225. Of course, in some alternative embodiments, the limiting protrusion 225 and the limiting recess 152 can also have other implementations. And, in some alternative embodiments, the positions of the limiting protrusion 225 and the limiting recess 152 on the arc wall 2201 and the protruding finger 15 can be interchanged.

[0052] In some embodiments, a locking identification portion 213 may be provided on the second housing 2 to indicate the locking state of the two connectors 100. The locking identification portion 213 includes, for example, a locking mark 2131 and a release mark 2132. When the clamping arm 14 of each connector 100 rotates in the direction of the locking mark 2131 in the recess 220, the two connectors 100 can be locked together through the limiting protrusion 225 and the limiting recess 152. When the clamping arm 14 of each connector 100 rotates in the direction of the release mark 2132 in the recess 220, the limiting protrusion 225 and the limiting recess 152 of the two connectors 100 can be released, and the two connectors 100 can then move away from each other in the direction of the rotation axis XX.

[0053] See also Figure 4 and Figure 8 The inner peripheral wall of the second end 12 of the first shell 1 includes an arcuate wall surface 1201, which extends from the end surface 121 into the accommodating cavity 10. The end surface 221 of the second end 22 of the second shell 2 has an arcuate protrusion 2211 extending toward the arcuate wall surface 1201, and an arcuate channel 202 is formed between the arcuate protrusion 2201 and the arcuate wall surface 1201. The end surface 221 of the second end 22 of the second shell 2 is also provided with an arcuate convex strip 226 protruding outward. The arcuate convex strip 226 extends from the end surface 221 in a direction substantially parallel to the rotation axis XX, and the arcuate convex strip 226 is opposite to the clamping arm 14.

[0054] When the two connectors 100 are connected, the clamping arm 14 of each connector 100 extends into the recess 220 of the other connector 100, and the arcuate ridge 226 of each connector 100 also extends into the arcuate channel 202 of the other connector 100. When the two connectors 100 rotate relative to each other around the rotation axis XX, each arcuate ridge 226 slides with the corresponding arcuate channel 202. The cooperation between the arcuate ridge 226 and the arcuate channel 202 further ensures that the two connectors 100 rotate relative to each other around the rotation axis XX, and can effectively prevent the two connectors 100 from accidentally separating after being connected in place, making the connection of the two connectors 100 more reliable.

[0055] See also Figure 3 and Figure 4 In some embodiments, the inner peripheral wall of the second end 12 of the first housing 1 further includes a boss 1203 protruding relative to the arc-shaped wall surface 1201. The boss 1203 can play a role in shielding the connection rope 3 located in the accommodating cavity 10. When two connectors 100 are connected, the end of the arc-shaped convex strip 226 of each connector 100 away from the end surface 221 can, for example, abut against the boss 1203. The structure of the boss 1203 does not interfere with the installation of the connection rope 3.

[0056] Second embodiment

[0057] Fig.13 and Fig.14 The figures show stereoscopic views of a connector 100 provided in accordance with a second embodiment of the present invention from different viewing angles. The connector 100 is a variation of the connector 100 in the first embodiment. Fig.15 and Fig.16 Exploded views of the connector 100 from different perspectives are shown. In the absence of conflict, the structure of the connector 100 of the second embodiment may refer to the structure of the connector 100 of the first embodiment.

[0058] In this embodiment, the first shell 1 and the second shell 2 of the connector 100 are not fixed together by the fastener 4, but are fixed together by snapping. Specifically, the first shell 1 is provided with snapping holes 16 on both sides of the rotation axis XX, and the snapping holes 16 are provided on the docking surface 131 and the docking surface 132, for example. The second shell 2 is provided with elastic arms 25 on both sides of the rotation axis XX, and the elastic arms 25 are provided on the docking surface 231 and the docking surface 232, for example. The ends of the elastic arms 25 may have protruding fingers 251. The elastic arms 25 may pass through the corresponding snapping holes 16, and are detachably snapped with the corresponding snapping holes 16 through the protruding fingers 251, so as to detachably connect the first shell 1 and the second shell 2 together.

[0059] Of course, in some alternative embodiments, the first housing 1 and the second housing 2 may also be connected by other suitable snap-fit ​​structures. For example, the structures of the snap-fit ​​holes 16 and the elastic arms 25 on the first housing 1 and the second housing 2 may be interchangeable. The number of the snap-fit ​​holes 16 and the elastic arms 25 may be modified as needed.

[0060] In this embodiment, the flat head end 1A of the connector 100 also includes two surfaces 11A and 21A that are separated from each other. Different from the first embodiment, the surface 11A and the surface 21A are respectively inclined relative to the rotation axis XX.

[0061] In this embodiment, the structures of the recesses 133 and the protrusions 233 are also modified. Specifically, each recess 133 can be a hole (e.g., a blind hole), and each protrusion 233 can be a convex column. When the first shell 1 and the second shell 2 are docked, the plurality of protrusions 233 cooperate with the plurality of recesses 133 to improve the connection strength of the first shell 1 and the second shell 2. In some embodiments, the cooperation between each protrusion 233 and the corresponding recess 133 is an interference fit.

[0062] See also Fig.15 and Fig.16 In this embodiment, the positioning member 24 extends from the first housing 1 toward the second housing 2, for example, along a direction perpendicular to the rotation axis XX. The positioning member 24 is, for example, closer to the through hole 101. A channel 242 for the connecting rope 3 to pass through is formed between the inner wall of the accommodating cavity 10 and the positioning member 24. The size of the channel 242 is designed to prevent the stopper 311 at the first end 31 of the connecting rope 3 from passing through.

[0063] In some embodiments, the positioning member 24 may also have a center hole 240. A connecting column 26 is provided at a position of the second shell 2 corresponding to the positioning member 24, and the connecting column 26 is used to be inserted into the center hole 240. The cooperation between the positioning member 24 and the connecting column 26 enhances the connection between the first shell 1 and the second shell 2 on the one hand, and enhances the structural strength of the positioning member 24 on the other hand. The cooperation between the connecting column 26 and the center hole 240 is, for example, an interference fit. In some alternative embodiments, the positions of the positioning member 24 and the connecting column 26 on the first shell 1 and the second shell 2 can be interchangeable. In some embodiments, the connecting column 26 has a tip to facilitate insertion into the center hole 240.

[0064] In some embodiments, after the first end 31 of the connecting rope 3 is placed in the accommodating cavity 10, during the assembly process of the first shell 1 and the second shell 2, the connecting column 26 can pierce the connecting rope 3 and then be inserted into the central hole 240. When the connecting rope 3 is subjected to tension, the stopper 311 can abut against the positioning member 24 and the connecting column 26 that are sleeved together, which is more conducive to preventing the first end 31 of the connecting rope 3 from detaching from the connector 100 through the through hole 101.

[0065] The embodiment of the utility model also provides a floating device, which includes a floating body (not shown in the figure), a connecting rope and the above-mentioned connector 100. The connecting rope is connected to the floating body, and the connector 100 is connected to the connecting rope. The floating body can be, for example, but not limited to, a plastic inflatable. Multiple floating bodies can be quickly connected together or quickly separated by means of their respective connectors 100.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
