[0055] like Figures 1 to 4 As shown, the locking device 1 of the present application includes a fixed frame 10 and a fixed seat 11. The middle portion of the fixed frame 10 has a hollow opening 101 that passes through the fixed frame 10. The fixed frame 10 has a protrusion 102 facing the hollow opening 101, and the fixed frame 10 is fixed to the boat or ship. The fixed seat 11 has a slot 110. The fixed seat 11 passes through the hollow opening 101, and the protrusion 102 is engaged with the slot 110, thereby fixing the fixed seat 11 to the fixed frame 10. The locking device 1 of the present application is mainly used for boats or ships. In actual use, the locking device 1 can be used to install the propulsion device 2 of the boat or ship on the boat or ship.

[0056] The locking device 11 of the present application includes a fixing seat 11 and a fixing frame 10. The fixing frame 10 is provided with a hollow opening 101. The fixing seat 11 passes through the hollow opening 101. The protrusion 102 of the fixing frame 10 facing the hollow opening 101 is engaged with the engagement groove 110 of the fixing seat 11, thereby locking the fixing frame 10 and the fixing seat 11, thereby achieving a connection between the boat or ship connected to the fixing frame 10 and the propulsion device 2 connected to the fixing seat 11. During disassembly, the fixing frame 10 is rotated so that the protrusion 102 of the fixing frame 10 is disengaged from the engagement groove 110 of the fixing seat 11, thereby separating the fixing seat 11 from the fixing frame 10, thereby separating the boat or ship from the propulsion device 2.

[0057] In this embodiment, the fixed seat 11 includes a seat body 111 and a seat edge 112. The seat body 111 includes a bottom wall 1110 and a side wall 1111 connected to the bottom wall 1110. The side wall 1111 and the bottom wall 1110 enclose a cavity 1112, and the seat body 111 extends through the hollow opening 101. The seat edge 112 is connected to the end of the side wall 1111 away from the bottom wall 1110 and extends away from the cavity 1112. The seat edge 112 is parallel to the bottom wall 1110, and a slot 110 is provided at the connection between the seat edge 112 and the side wall 1111. The provision of the seat edge 112 allows the fixed seat 11 to be locked to the fixed frame 10 and enables the protrusion 102 of the fixed frame 10 to be engaged or disengaged from the slot 110 of the fixed seat 11. The cavity 1112 enclosed by the bottom wall 1110 and the side wall 1111 can accommodate the main shaft and other structures of the propulsion device 2.

[0058] In this embodiment, a through hole 40 is provided on the bottom wall 1110, and the through hole 40 allows the main shaft of the propulsion device 2 to extend out of the fixing seat 11 and connect to the propeller. The propulsion device 2 and the fixing seat 11 can be fixed by setting a structure on the hole wall of the through hole 40, or by setting a second fixing hole 114 on the fixing seat 11. Figures 13 to 15 The fixing base 11 is provided with a second fixing hole 114 , and the fixing base 11 is connected to a propulsion device 2 through the second fixing hole 114 .

[0059] In this embodiment, the side wall 1111 has a groove 113 that is recessed into the cavity 1112. The groove 113 extends from the bottom wall 1110 toward the seat edge 112, and the groove 113 is connected to the latching slot 110. The main function of the groove 113 is that when the fixing seat 11 and the fixing frame 10 are fixed or removed, the protrusion 102 of the fixing frame 10 can slide along the groove 113 and can slide from the groove 113 into the latching slot 110 or from the latching slot 110 into the groove 113, thereby facilitating the fixing and disconnection of the fixing seat 11 and the fixing frame 10, thereby allowing the propulsion device 2 to be fixed to or disconnected from the boat or ship.

[0060] In this embodiment, after the protrusion 102 of the fixed frame 10 slides along the groove 113 until it contacts the seat edge 112, rotating the fixed seat 11 can also rotate the fixed frame 10, and the protrusion 102 moves from the groove 113 to the engaging groove 110, thereby securing the fixed seat 11 to the fixed frame 10. Rotating the fixed frame 10 engages the protrusion 102 in the engaging groove 110 to secure the fixed frame 10. This has a simple structure, is easy to operate, and saves effort, allowing for efficient assembly and disassembly of the fixed frame 10 and the fixed seat 11.

[0061] In this embodiment, the fixing frame 10 is a circular ring having a hollow opening 101 in the middle thereof, and the protrusion 102 is provided on the side of the ring facing the hollow opening 101. The circular shape of the fixing frame 10 is easy to manufacture, and the fixing frame 10 and the fixing seat 11 can be assembled and disassembled simply by rotating them, thereby reducing costs.

[0062] In this embodiment, there are six protrusions 102, spaced apart. The number of protrusions 102 can be set based on the size of the ring and can range from two to more. The spaced apart arrangement can improve the comprehensiveness of the fixation between the fixing frame 10 and the fixing seat 11. The number of protrusions 102 is the same as the number of slots 110. In other embodiments, the number of protrusions 102 can also be two, three, four, five, seven, eight, etc. The number of protrusions 102 can also be different from the number of slots 110, or the number of protrusions 102 can be less than the number of slots 110.

[0063] In this embodiment, the fixing frame 10 is provided with a first fixing hole 104 , and the fixing frame 10 is connected to the boat or ship through the first fixing hole 104 .

[0064] like Figure 5 and Figure 7 As shown, when the locking device 1 is not locked, the protrusion 102 is not locked in the slot 110, but is located in the groove 113 and abuts the seat edge 112.

[0065] like Figure 6 and Figure 8 As shown, when the locking device 1 is locked, the protrusion 102 is locked in the locking groove 110, and the fixing frame 10 and the fixing seat 11 are fixed together.

[0066] In this embodiment, an elastic sheet 103 is provided on the surface of the fixing frame 10 away from the fixing seat 11. When the protrusion 102 is engaged with the card slot 110, the elastic sheet 103 is stopped to prevent the protrusion 102 of the fixing frame 10 from being separated from the card slot 110. The manner in which the elastic sheet 103 is stopped can be seen in Figure 15 The stop structure 201 and the elastic sheet 103 of the propulsion device 2 are shown. In this embodiment, since the fixing frame 10 is a circular ring structure, the corresponding housing 20 of the propulsion device 2 needs to be provided with a portion for mounting the stop structure 201, or the housing 20 of the propulsion device 2 can also be set to a circular shape.

[0067] like Figures 12 to 15 This is another embodiment of the locking device 1 of the present application. Figures 1 to 8 Therefore, in the following description of the locking device 1 of the other embodiment, the description of the locking device 1 is not repeated. Figures 1 to 8 In addition, Figures 1 to 8 The same reference numerals are used for the same structures as those of the locking device 1 described in the embodiment of FIG. Figures 1 to 8 The difference between the locking device 1 of the embodiment of the present invention is described. Among them, the locking device 1 of the other embodiment is mainly the shape of the locking device 1 and the Figures 1 to 8 The shape of the locking device 1 is different.

[0068] In this embodiment, the fixing frame 10 includes a first side 1001, a second side 1002, a third side 1003, and a fourth side 1004, which are connected end to end. The first side 1001, the second side 1002, the third side 1003, and the fourth side 1004 define a hollow opening 101. Protrusions 102 are provided on the first side 1001 and the third side 1003. Correspondingly, the fixing seat 11 also takes the form of a rectangular parallelepiped, and the seat edge 112 also adopts a similar four-sided design.

[0069] In this embodiment, the number of protrusions 102 is six, but may be two or more. In this embodiment, three protrusions 102 are provided on each of the first side 1001 and the third side 1003, with the three protrusions 102 spaced apart. In an embodiment with two protrusions 102, one protrusion 102 is provided on each of the first side 1001 and the third side 1003. Typically, the number of protrusions 102 on the first side 1001 and the third side 1003 is equal. In some embodiments, the number of protrusions 102 on the first side 1001 and the third side 1003 may be unequal.

[0070] In this embodiment, a limiting structure 105 is provided on the second side 1002, and a limiting groove 115 is provided on the portion of the fixing base 11 corresponding to the second side 1002. The limiting structure 105 is limited in the limiting groove 115. The design of the limiting structure 105 and the limiting groove 115 can limit and fix the fixing frame 10 to the fixing base 11, further limiting the relative movement between the two.

[0071] In this embodiment, after the protrusion 102 of the fixed frame 10 slides along the groove 113 to contact the seat edge 112, it pushes the fixed frame 10 and can also push the fixed seat 11. The protrusion 102 moves from the groove 113 to the slot 110 to fix the fixed seat 11 and the fixed frame 10.

[0072] In this embodiment, see Figures 13 to 15 The fixing frame 10 is provided with a first fixing hole 104 , and the fixing seat 11 is provided with a second fixing hole 114 . The fixing frame 10 is connected to a boat or ship through the first fixing hole 104 , and the fixing seat 11 is connected to a propulsion device 2 through the second fixing hole 114 .

[0073] In this embodiment, see Figure 15 One end of the fixing seat 11 is connected to a propulsion device 2, and the other end is connected to the propeller assembly 14. The propulsion device 2 can drive the blades of the propeller assembly to rotate. The propulsion device 2 includes a housing 20, and a stop structure 201 is provided on the housing 20. An elastic sheet 103 is provided on the surface of the fixing frame 10 away from the fixing seat 11. When the protrusion 102 is engaged with the slot 110, the stop structure 201 stops the elastic sheet 103 to prevent the protrusion 102 of the fixing frame 10 from being separated from the slot 110. There can also be two or more stop structures 201, and the corresponding elastic sheets 103 can also be two or more. In this embodiment, there are two elastic sheets 103, which are respectively provided on the first side 1001 and the third side 1003 of the fixing frame 10.

[0074] The present application also provides a kayak, comprising a kayak body and a locking device 1, wherein the locking device 1 is the same as the above locking device 1, and a fixing frame 10 of the locking device 1 is fixed to the kayak body. This method is mainly used for hard-shell kayaks.

[0075] The present application also provides a kayak, comprising a kayak body, a connecting seat 3, and a locking device 1. The kayak body is provided with a bottom hole. One end of the connecting seat 3 is fixed to the kayak body, and the other end passes through the bottom hole and is fixedly connected to the locking device 1. The locking device 1 adopts the locking device 1 described above. This method is mainly used for inflatable kayaks.

[0076] The connection seat 3 can refer to Figures 9 to 11 As shown, the connector 3 includes a base 31, a connecting wall 32, a connecting post 33, and a connecting hole 34. The connecting hole 34 corresponds one-to-one with the first fixing hole 104 of the fixing frame 10. The fixing frame 10 can be connected to the connector 3 using bolts or other fasteners. The connector 3 is then mounted to the boat body, thereby attaching the fixing frame 10 to the boat body. The use of the connector 3 for fastening is primarily used for inflatable kayaks. The connection between the connector 3 and the kayak can be a conventional detachable connection method such as a threaded connection.

[0077] In this exemplary embodiment, the locking device 1 proposed in this application is described using the kayaking field as an example. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below to apply the relevant designs of this application to other fields, and such modifications remain within the scope of the principles of the locking device 1 proposed in this application.

[0078] It should be noted that the locking devices 1 shown in the drawings and described in this specification are only a few examples of the many types of locking devices 1 that can employ the principles of the present application. It should be clearly understood that the principles of the present application are by no means limited to any component of any detail of the locking device 1 shown in the drawings or described in this specification.

[0079] The above is a detailed description of several exemplary embodiments of the locking device 1 proposed in the present application. The following is an exemplary description of the use process of the locking device 1 proposed in the present application.

[0080] Combined with attachment Figures 1 to 15 The use process of the locking device 1 proposed in this application is as follows:

[0081] Example 1: Using Figures 1 to 8 The locking device of the illustrated embodiment is used for a hard-shell kayak.

[0082] The locking device 1's fixing frame 10 is fixed to the kayak's bottom through the first fixing hole 104. The bottom has a bottom hole, and the location of the hollow opening 101 of the fixing frame 10 overlaps with the location of the bottom hole. The propulsion device 2 is fixedly connected to the fixing base 11 through the second fixing hole 114. The main shaft of the propulsion device 2 extends through the cavity 1112 of the base 111 of the fixing base 11, extends out of the fixing base 11, and is connected to the propeller.

[0083] The propeller, main shaft and fixing seat 11 are passed through the hollow opening 101 of the fixing frame 10, wherein the protrusion 102 of the fixing frame 10 moves from the bottom wall 1110 to the seat edge 112 along the groove 113 of the seat body 111 of the fixing seat 11, so that the fixing seat 11 passes through the bottom of the boat and is located below the bottom of the boat, and the seat edge 112 of the fixing seat 11 is stuck on the surface of the fixing frame 10 away from the seat body 111 of the fixing seat 11.

[0084] At this time, the protrusion 102 of the fixed frame 10 contacts the seat edge 112 of the fixed seat 11. The fixed frame 10 or the fixed seat 11 is rotated so that the protrusion 102 of the fixed frame 10 slides from the groove 113 of the fixed seat 11 into the slot 110 of the fixed seat 11, thereby fixing the fixed frame 10 and the fixed seat 11.

[0085] At the same time, the elastic sheet 103 on the fixing frame 10 is stopped by the stop structure 201 on the shell 20 of the propulsion device 2 after it bounces up, so that the protrusion 102 of the fixing frame 10 cannot slide from the slot 110 of the fixing seat 11 into the groove 113 of the fixing seat 11, thereby achieving a firm and stable fixed connection between the fixing frame 10 and the fixing seat 11, thereby achieving a stable and firm connection between the propulsion device 2 and the kayak.

[0086] When the propulsion device 2 needs to be removed from the kayak, the elastic piece 103 of the fixing frame 10 is pressed so that the stop structure 201 of the propulsion device 2 no longer stops the elastic piece 103. Then, the fixing frame 10 or the fixing seat 11 is rotated in the opposite direction so that the protrusion 102 of the fixing frame 10 slides from the locking groove 110 of the fixing seat 11 into the groove 113 of the fixing seat 11, thereby disengaging the protrusion 102 from the locking groove 110. Then, the fixing seat 11 and the propulsion device 2 are lifted upward from the fixing frame 10, and the fixing frame 11 and the fixing frame 10 are disengaged, and the propulsion device 2 is removed from the kayak.

[0087] Example 2: Using Figures 12 to 15 The locking device of the illustrated embodiment is used for a hard-shell kayak.

[0088] The locking device 1's fixing frame 10 is fixed to the kayak's bottom through the first fixing hole 104. The bottom has a bottom hole, and the location of the hollow opening 101 of the fixing frame 10 overlaps with the location of the bottom hole. The propulsion device 2 is fixedly connected to the fixing base 11 through the second fixing hole 114. The main shaft of the propulsion device 2 extends through the cavity 1112 of the base 111 of the fixing base 11, extends out of the fixing base 11, and is connected to the propeller.

[0089] The propeller, main shaft and fixing seat 11 are passed through the hollow opening 101 of the fixing frame 10, wherein the protrusion 102 of the fixing frame 10 moves from the bottom wall 1110 to the seat edge 112 along the groove 113 of the seat body 111 of the fixing seat 11, so that the fixing seat 11 passes through the bottom of the boat and is located below the bottom of the boat, and the seat edge 112 of the fixing seat 11 is stuck on the surface of the fixing frame 10 away from the seat body 111 of the fixing seat 11.

[0090] At this time, the protrusion 102 of the fixed frame 10 contacts the seat edge 112 of the fixed seat 11, pushing the fixed frame 10 or the fixed seat 11, so that the protrusion 102 of the fixed frame 10 slides from the groove 113 of the fixed seat 11 into the card slot 110 of the fixed seat 11, thereby fixing the fixed frame 10 and the fixed seat 11.

[0091] At the same time, the elastic sheet 103 on the fixed frame 10 is stopped by the stop structure 201 on the shell 20 of the propulsion device 2 after it bounces up, so that the protrusion 102 of the fixed frame 10 cannot slide from the slot 110 of the fixed seat 11 into the groove 113 of the fixed seat 11. At the same time, the limiting structure 105 is combined with the limiting groove 115 to achieve a firm and stable fixed connection between the fixed frame 10 and the fixed seat 11, thereby achieving a stable and firm connection between the propulsion device 2 and the kayak.

[0092] When the propulsion device 2 needs to be removed from the kayak, the elastic sheet 103 of the fixing frame 10 is pressed so that the stop structure 201 of the propulsion device 2 no longer stops the elastic sheet 103. Then, the fixing frame 10 or the fixing seat 11 is pushed in the opposite direction so that the protrusion 102 of the fixing frame 10 slides from the locking groove 110 of the fixing seat 11 into the groove 113 of the fixing seat 11, thereby disengaging the protrusion 102 from the locking groove 110 and simultaneously disengaging the limiting structure 105 from the limiting groove 115. Then, the fixing seat 11 and the propulsion device 2 are lifted upward from the fixing frame 10, and the fixing frame 11 and the fixing frame 10 are disengaged, and the propulsion device 2 is removed from the kayak.

[0093] Example 3, using Figures 1 to 8 The locking device of the illustrated embodiment is used for an inflatable kayak.

[0094] Inflatable kayaks require Figures 9 to 11 The connecting seat shown has a bottom hole on the bottom of the kayak. The connecting seat 3 is installed on the bottom of the kayak through the bottom hole. The fixing frame 10 of the locking device 1 is installed on the connecting seat 3 through the first fixing hole 104 and the connecting hole 34 of the connecting seat 3. The connecting seat 3 has a connecting hole 34. The position of the connecting hole 34 and the position of the hollow opening 101 of the fixing frame 10 overlap with the position of the bottom hole.

[0095] The propulsion device 2 is connected to the second fixing hole 114 of the fixing seat 11 , wherein the main shaft of the propulsion device 2 passes through the cavity 1112 of the base body 111 of the fixing seat 11 and extends out of the fixing seat 11 and is connected to the propeller.

[0096] The propeller, main shaft and fixing seat 11 are passed through the hollow opening 101 of the fixing frame 10, wherein the protrusion 102 of the fixing frame 10 moves from the bottom wall 1110 to the seat edge 112 along the groove 113 of the seat body 111 of the fixing seat 11, so that the fixing seat 11 passes through the bottom of the boat and is located below the bottom of the boat, and the seat edge 112 of the fixing seat 11 is stuck on the surface of the fixing frame 10 away from the seat body 111 of the fixing seat 11.

[0097] At this time, the protrusion 102 of the fixed frame 10 contacts the seat edge 112 of the fixed seat 11. The fixed frame 10 or the fixed seat 11 is rotated so that the protrusion 102 of the fixed frame 10 slides from the groove 113 of the fixed seat 11 into the slot 110 of the fixed seat 11, thereby fixing the fixed frame 10 and the fixed seat 11.

[0098] At the same time, the elastic sheet 103 on the fixing frame 10 is stopped by the stop structure 201 on the shell 20 of the propulsion device 2 after it bounces up, so that the protrusion 102 of the fixing frame 10 cannot slide from the slot 110 of the fixing seat 11 into the groove 113 of the fixing seat 11, thereby achieving a firm and stable fixed connection between the fixing frame 10 and the fixing seat 11, thereby achieving a stable and firm connection between the propulsion device 2 and the kayak.

[0099] When the propulsion device 2 needs to be removed from the kayak, the elastic piece 103 of the fixing frame 10 is pressed so that the stop structure 201 of the propulsion device 2 no longer stops the elastic piece 103. Then, the fixing frame 10 or the fixing seat 11 is rotated in the opposite direction so that the protrusion 102 of the fixing frame 10 slides from the locking groove 110 of the fixing seat 11 into the groove 113 of the fixing seat 11, thereby disengaging the protrusion 102 from the locking groove 110. Then, the fixing seat 11 and the propulsion device 2 are lifted upward from the fixing frame 10, and the fixing frame 11 and the fixing frame 10 are disengaged, and the propulsion device 2 is removed from the kayak.

[0100] When storage is required, the connecting seat 3 can be removed from the kayak, and the inflatable kayak can be deflated and folded.

[0101] Example 4 can be used Figure 12 system Figure 15 The locking device of the embodiment shown is used for an inflatable kayak. Accordingly, the shape of the connecting seat 3 will also be adaptively changed with the shape of the locking device. For example, Figures 9 to 11 The shape of the connecting seat is changed to a rectangular parallelepiped, and the rest of the contents are roughly similar to those of the second and third embodiments, and will not be repeated here.

[0102] Through the above-mentioned use process of the locking device 1 of the present application, it can be concluded that the locking device 1 of the present application is provided with a hollow opening 101, and the fixing seat 11 passes through the hollow opening 101. The protrusion 102 of the fixing frame 10 facing the hollow opening 101 is engaged with the engaging groove 110 of the fixing seat 11, thereby achieving the locking of the fixing frame 10 and the fixing seat 11, thereby achieving the connection between the boat or ship connected to the fixing frame 10 and the propulsion device 2 connected to the fixing seat 11. During disassembly, the fixing frame 10 is rotated or pushed so that the protrusion 102 of the fixing frame 10 is disengaged from the engaging groove 110 of the fixing seat 11, so that the fixing seat 11 can be separated from the fixing frame 10, thereby achieving the separation of the boat or ship from the propulsion device 2.
