Description

Technical Field

[0001] This utility model relates to the field of trailer frame technology, specifically a surfboard trailer frame that is simple in structure, easy to install and disassemble, has high assembly and disassembly efficiency, and is easy to store. Background Technology

[0002] As is well known, surfing is a sport that uses ocean waves as its power source and relies on the user's skill and balance to ride them. Users stand on a surfboard, or use a belly board, kneeboard, inflatable pad, rowboat, kayak, or other similar equipment to control the waves.

[0003] Currently, due to the structural limitations of surfboards, they cannot be stored and are generally transported by truck when in use. However, most surfers do not have trucks and cannot transport surfboards. Therefore, for the sake of portability, surfboards are usually attached to the back of a vehicle and then to the top of a trailer. However, trailers are bulky and inconvenient for storage and transportation later. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a surfboard trailer frame that is simple in structure, easy to install and disassemble, has high assembly and disassembly efficiency, and is easy to store.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A surfboard trailer frame, characterized in that the trailer frame includes a socket plate, a support plate, connecting rods and rollers, wherein the lower end of the socket plate is connected to the support plate, the lower end of the support plate is connected to the connecting rods, and rollers are fitted on the connecting rods on the left and right sides of the support plate, and the socket plate is inserted into the tail fin fixing seat at the bottom of the surfboard.

[0006] The support plate of this utility model has a slot with one open end on its lower side, and a snap-fit ​​hole is provided above the end of the slot. The middle part of the connecting rod is inserted into the snap-fit ​​hole through the slot.

[0007] The support plate of this utility model includes a connecting part and a U-shaped support part. The connecting part is plate-shaped, with its upper end connected to the socket plate and its lower end connected to the middle of the horizontal plate of the U-shaped support part. The two side plates of the U-shaped support part face downward and are symmetrically provided with slots, and the connecting hole is located above the end of the slot.

[0008] The support plates or side plates on both sides of the snap-fit ​​hole described in this utility model are respectively provided with reinforcing protrusions. The reinforcing protrusions increase the contact surface between the connecting rod and the snap-fit ​​hole, ensuring the stability of the connection between the connecting rod and the support plate.

[0009] The roller of this utility model has an insertion hole in the middle, and the two ends of the connecting rod are respectively provided with threaded grooves or annular grooves. The two ends of the connecting rod are inserted into the middle of the roller through the insertion hole and then connected to the locking nut or retaining ring.

[0010] The slot described in this invention has its opening facing the rear of the entire trailer frame.

[0011] The slot described in this invention has an opening width smaller than the diameter of the connecting rod, thus preventing the connecting rod from falling off.

[0012] The socket plate and the support plate of this utility model are provided with a plug hole at the connection point. A pin plate is provided in the plug hole. After the socket plate is inserted into the tail fin fixing seat at the tail of the surfboard, the pin plate passes through the tail fin fixing seat and the plug hole and is fixed on the tail fin fixing seat.

[0013] The socket plate described in this utility model has a cross-section that matches the T-shaped groove on the tail fin mounting base.

[0014] The roller described in this invention has an annular retainer on the connecting rod inside the roller, and the roller is secured between the annular retainer and a locking nut or retaining ring.

The two ends of the connecting rod 2 are inserted into the middle of the roller 3 through the socket hole and then connected with the retaining ring. The socket plate 1 and the support plate 18 are provided with a plug hole 10. The plug hole 10 is provided with a pin plate 11. After the socket plate 1 is inserted into the tail fin fixing seat 6 at the tail of the surfboard, the pin plate 11 passes through the tail fin fixing seat 6 and the plug hole 10 and is fixed on the tail fin fixing seat 6. The cross section of the socket plate 1 is a T-shaped structure that matches the T-shaped groove on the tail fin fixing seat 6. The connecting rod 2 on the inner side of the roller 3 is provided with an annular slot 15. The roller 3 is locked between the annular slot 15 and the retaining ring.

[0040] The support plate 18 of this connection method is a plate-shaped support plate 18 structure.

[0041] The method for assembling the trailer frame is to directly connect the connecting rod to the support plate 18 as a single unit, and then insert the rollers onto the connecting rods and lock them in place by locking the connection with the snap rings in the annular slots 16.

[0042] After the trailer frame with the above three connection methods is assembled, when using it, first fix the tail fin mounting base 6 to the bottom of the surfboard. The tail fin mounting base 6 has a T-shaped groove 14 with an opening at the rear end. The outer side of the front end of the T-shaped groove 14 has a plug groove 13 that is perpendicular to the T-shaped groove 14 and corresponds to the position of the plug hole 10. When transporting the surfboard, connect both ends of the connecting rod 2 to the rollers 3 respectively. Insert the socket plate 1 into the T-shaped groove 14 through the opening of the tail fin mounting base 6. Then insert the pin plate 11 into the plug hole 10 and the plug groove 13 of the tail fin mounting base 6. After that, insert the rod part of the connecting rod 2 with rollers 3 at both ends through the slot 4 and then lock it into the locking hole 5, thereby realizing the connection between the rollers 3 and the connecting rod. The surfboard is connected to the trailer frame via a hook or connecting rope. The surfboard can be moved by the car. Due to the weight of the surfboard, it presses down on the trailer frame, while the roller 3 lifts the connecting rod 2, allowing the connecting rod 2 to fit better into the locking hole 5. After transportation to the destination, the plug plate 11, socket plate 1, and connecting rod 2 can be removed, and the connecting rod 2 can be detached from the roller 3 for easy storage of the trailer frame. The installation and disassembly are convenient and efficient. Due to the design of the plug plate 11, the socket plate can be prevented from detaching from the T-slot 14. This utility model has the advantages of simple structure, convenient installation and disassembly, high efficiency, and easy storage due to the above structure.
