[0034] See also Figure 1-10 , a pontoon fast assembly rigid joint, for easy operation, the rigid joint is specifically embedded and installed on the surfaces of two corresponding assembled pontoons, such as A pontoon 1 and B pontoon 8, the rigid joint comprises a gate-type gate block 5, a conical latch 6, a movable wedge block 7 and an A connection box structure 2 and a B connection box structure 9 respectively installed on the two assembled pontoons, the A connection box structure 2 and the B connection box structure 9 need to be pre-embedded into the surfaces of the A pontoon 1 and the B pontoon 8; that is, the A connection box structure 2 is embedded on the edge of the surface of the assembled A pontoon 1, the B connection box structure 9 is embedded on the edge of the surface of the assembled B pontoon 8, and the two assembled A and B pontoons (1, 8) can ensure that the A connection box structure 2 and the B connection box structure 9 are close to each other. The respective side openings are set.

[0035] like Figure 3 As shown, the A and B connection box structures (2 and 9) are composed of a square body structure, and the top surface and an adjacent side surface of the A and B connection box structures (2 and 9) are both opened.

[0036] like Figure 1 As shown, the A connection box structure 2 is provided with an A lock block 3 and two fixed wedge blocks 4; and the A lock block 3 is ensured to be installed on the lower edge of the side opening of the A connection box structure 2, and the two fixed wedge blocks 4 are three-dimensionally arranged parallel to each other on the side opposite to the side opening surface.

[0037] like Figure 3 As shown, a B locking block 10 is provided in the B connection box structure 9 , and the B locking block 10 is ensured to be installed on the lower edge of the side opening of the B connection box structure 9 .

[0038] like Figure 5 As shown, the inner sides of the two side surfaces of the gate-shaped gate block 5 are open shapes that are wider at the bottom and narrower at the top, forming a wedge-shaped surface 501, and the gate-shaped gate block 5 can just fit the A and B lock blocks (3, 10) therein; an opening 502 is also provided on one of the wedge-shaped side surfaces of the gate-shaped gate block 5.

[0039] like Figure 7 As shown, the tapered latch pin 9 is a cone structure, and its cross-sectional shape is circular, and can also be set to a regular polygonal structure as required.

[0040] like Figure 9-10As shown, the cross-section of the A and B lock blocks (3, 10) is a right-angled trapezoid, and ensures that the right-angled surface of the A lock block 3 faces the outside of the A connection box structure 2, and the inclined surface of the A lock block 3 is installed toward the inside of the A connection box structure 2; similarly, the right-angled surface of the B lock block 10 faces the outside of the B connection box structure 9, and the inclined surface of the B lock block 10 is installed toward the inside of the B connection box structure 9; the installation in this order is to ensure that the door-type gate block 5 can completely insert the A and B lock blocks (3, 10) into the door shape of the door-type gate block 5 after the A and B lock blocks (3, 10) are completely fitted.

[0041] like Figure 1 As shown, the inclination angle of the inclined surface edge of the A and B lock blocks (3, 10) facing the inner side of the connection box is the same as the angle of the vertical wedge surface 501 set on the inner side of the door-shaped gate block 5, so as to ensure that the door-shaped gate block 5 and the A and B lock blocks (3, 10) fit more closely.

[0042] like Figure 2-3 As shown, the A lock block 3 and the B lock block 10 are arranged correspondingly at the installation positions of the respective A and B connection box structures (2, 9); the A and B lock blocks (3, 10) are provided with an A tapered hole 301 and a B tapered hole 1001 matching the taper of the tapered plug pin 6 at the center of the surface, and can ensure that the tapered plug pin 6 can be smoothly inserted into the A tapered hole 301 and the B tapered hole 1001 of the A and B lock blocks (3, 10) for installation and connection.

[0043] like Figure 2 and 8 As shown, the two vertical surfaces 701 of the movable wedge block 7 that bear working force are wedge-shaped, and the movable wedge block 7 is inserted between the conical pin and the ends of the two fixed wedge blocks 4.

[0044] The two fixed wedge blocks 4 are arranged in parallel in the A connection box structure 2, and their outer working force surfaces 401 are aligned with each other and have the same wedge angle as the movable wedge block 7; the parallel surface distance between the two fixed wedge blocks 7 is greater than the maximum dimension of the cross section of the conical pin 6.

[0045] The specific installation method of the present invention is as follows: the A connection box structure 2 and the B connection box structure 9 need to be pre-embedded into the surface of the A pontoon 1 and the B pontoon 8 for installation and fixation; two fixed wedge blocks 4 are fixed in parallel to each other in the A connection box structure 2; the A and B lock blocks (3, 10) are respectively fixed at the lower edge of the side openings of the A connection box structure 2 and the B connection box structure 9; when the A pontoon 1 and the B pontoon 8 need to be assembled, the A pontoon 1 and the B pontoon 8 are brought close to each other and the A and B lock blocks (3, 10) are completely fitted together, and the door-shaped gate block 5 is buckled from top to bottom on both sides of the A lock block 3 and the B lock block 10, and the A connection box structure 2 and the B connection box structure 9 are fixed to each other by the effect of the wedge-shaped inclined surface. This close combination gate is buckled, so that the A buoyancy box 1 and the B buoyancy box 8 are closely fitted together; further, the conical pin 6 is inserted from the A connecting box structure 2 through the A conical hole 301 in the A lock block 3 and the B conical hole 1001 on the B lock block 10 in sequence, until the conical pin 6 contacts the B conical hole 1001, and then the movable wedge block 7 is inserted from top to bottom between the rear end of the conical pin 6 and the two fixed wedge blocks 4, the inclined surface of the movable wedge block 7 contacts the inclined surfaces of the two fixed wedge blocks 4, and the opposite side plane of the inclined surface of the movable wedge block 7 contacts the rear end surface of the conical pin 6, and the movable wedge block 7 moves downward to push the conical pin 6 to move axially, thereby locking the conical pin 6 with the conical holes of the A lock block 3 and the B lock block 10.

[0046] The locking between the gate-shaped gate block 5 and the A lock block 3 and the B lock block 10 makes the A pontoon 1 and the B pontoon 8 close to each other and cannot be separated. The locking between the conical latch 6 and the conical holes of the A lock block 3 and the B lock block 10 makes the A pontoon 1 and the B pontoon 8 locked in the other directions and cannot be separated, thereby realizing the rigid connection of the two pontoons.

[0047] When the A pontoon 1 and the B pontoon 8 are disassembled, the movable wedge block 7 is pulled out upward in the reverse order of assembly, the tapered latch 6 is withdrawn from the tapered holes of the A lock block 3 and the B lock block 10, and finally the door-shaped gate block 5 is lifted upward to separate from the A lock block 3 and the B lock block 10. At this point, the disassembly of the A pontoon 1 and the B pontoon 8 is completed, and the disassembly operation can be performed with the aid of handheld auxiliary tools.

[0048] In this embodiment, the door-shaped brake block 5 has an opening 502 on the wedge-shaped plate on one side of the B lock block. The front end of the conical latch 6 is inserted into the hole after assembly to prevent the door-shaped brake block 5 from accidentally detaching.

[0049] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific embodiments, which are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can make many forms without departing from the scope of protection of the present invention and the claims, all of which fall within the scope of protection of the present invention.
