Description

Technical Field

[0001] This utility model relates to the field of inflatable boat keel technology, specifically a quick-installation inflatable boat keel connecting device. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to improving their quality of life. Inflatable boats, as a type of water transportation, bring people a variety of experiences such as leisure, entertainment, and fishing. Ordinary inflatable boats use an inflatable keel, an air-cushioned hull, and a wooden stern. The keel, as a longitudinal component connecting the bow and sternposts in the center of the hull's base, is an important part of the boat. It mainly bears the longitudinal bending moment of the hull, and its structural design directly affects the boat's performance and quality.

[0003] In the prior art, a Chinese patent discloses a connection structure for inflatable boats and keels (authorization announcement number CN211996049U). This patented technology can achieve a combination of stability and detachability by setting a linkage mechanism, which not only ensures the stability of the keel connection process, but also facilitates disassembly and installation.

[0004] In the aforementioned application, a connecting rod is used to connect the hinged seat and the ball joint. The connecting rod contains a spring, and the spring force generated during connection is significant. This makes it difficult for workers with less strength to connect the connecting rod to the ball joint, thus reducing installation efficiency. Therefore, a quick-installation inflatable boat keel connecting device is provided to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-installation inflatable boat keel connection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-installation inflatable boat keel connection device includes a tail plate, on which a plug-in seat is fixedly connected. A keel body is inserted into the plug-in seat. Hinges are fixedly connected to both the upper and lower sides of the keel body. Ball joints are provided on both the upper and lower sides of the plug-in seat. A connecting rod assembly is connected between the ball joints. The connecting rod assembly includes a first connecting rod and a second connecting rod. A connecting rod is fixedly connected to one end of the first connecting rod, and the connecting rod is inserted into the second connecting rod. A flange is fixedly connected to the adjacent ends of the first and second connecting rods. A fastening screw is screwed between the flanges, and a fastening nut is sleeved on the tail end of the fastening screw.

[0008] As a further embodiment of this utility model: symmetrical sliding rods are fixedly connected inside the plug-in seat, the sliding rods pass through the keel body, a shock-absorbing pad is fixedly connected between the keel body and the plug-in seat, a shock-absorbing spring is sleeved on the sliding rod, and a limit nut is sleeved on the sliding rod.

[0009] As a further embodiment of this utility model: the embedded ball is engaged inside the ball connector, a limiting screw is helically connected to the ball connector, the limiting screw is helically connected to the embedded groove, and a fixing nut is sleeved on the tail end of the limiting screw.

[0010] As a further embodiment of this utility model: the hinge seat is provided with a connecting groove, and a hinge rod is hingedly provided inside the connecting groove.

[0011] As a further embodiment of this utility model: one end of the second connecting rod is provided with a slot, the inside of the slot is provided with a groove, a guide post is fixedly connected inside the groove, and a fastening spring is sleeved on the guide post.

[0012] As a further embodiment of this utility model: the hinge rod has a through hole, the guide post and the through hole are mating components, and the groove is hooked onto the hinge rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] First, the embedded ball on the first connecting rod is connected to the inside of the ball joint and secured with a limiting screw and a fixing nut. Then, the groove on the second connecting rod is hooked onto the hinge rod, and the guide post is inserted into the through hole on the hinge rod. Next, the connecting rod is inserted into the inside of the second connecting rod, and then a fastening screw is connected to the flange. As the fastening screw rotates, it will cause the first and second connecting rods to move closer together until they are adjacent to a certain position. Then, a fastening nut is fitted onto the fastening screw to fix its position on the first and second connecting rods, preventing them from loosening. This structure can prevent workers with less strength from failing to connect the two ends of the first and second connecting rods to the ball joint and hinge seat, thereby improving installation efficiency.
