[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When it is necessary to move the inflatable boat onto the main body of the transfer vehicle, drive the telescopic rod. The telescopic rod extends and pushes the sliding frame downward. The downward movement of the sliding frame brings the support wheel into contact with the ground. The support wheel, sliding frame, and telescopic rod support the rear of the main body of the transfer vehicle. Then, move the inflatable boat onto the main body of the transfer vehicle. Then retract the telescopic rod. The telescopic rod pulls the sliding frame upward, pushing the support wheel to move upward as well. The support wheel moves and contacts the rear of the inflatable boat, restricting the inflatable boat from sliding to the rear. This makes it easier to support the main body of the transfer vehicle and the rear of the inflatable boat, improving work efficiency.

[0014] 2. When the assault boat is pushed into the main body of the transfer vehicle, the head of the assault boat enters between the two sets of protective arms and moves to contact the rollers. The rollers push the two sets of protective arms to unfold outward. At the same time as the protective arms unfold, the torsion spring is stressed. Through the reaction force of the torsion spring, the rollers press against the side wall of the head of the assault boat. The screw is rotated, and the screw threaded connection fixing plate moves to one side of the assault boat, pushing the protective plate to press against the head of the assault boat, restricting the assault boat from moving to one side of the head. This allows the support mechanism to stably limit the movement of the assault boat and provides multi-point support for the head of the assault boat. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 A device for preventing the inflatable boat transfer vehicle from falling off includes a transfer vehicle body 1, on which an inflatable boat 2 is placed. A limiting plate 3 is provided on the side wall of the transfer vehicle body 1 to restrict the longitudinal movement of the inflatable boat 2. A support mechanism 4 is provided on the transfer vehicle body 1 below the stern of the inflatable boat 2. The support mechanism 4 is used to support the transfer vehicle body 1 and to restrict the inflatable boat 2 from sliding away from the fixed plate 51. The support mechanism 4 includes a telescopic rod 41 located at the bottom of the transfer vehicle body 1. The extended end of the telescopic rod 41 is connected to a sliding frame 42 and is used to push the sliding frame 42 up and down. The bottom of the sliding frame 42 is provided with a support wheel 43 for moving to contact the ground. The top of the sliding frame 42 is provided with a support wheel 44 for moving to contact the stern of the inflatable boat 2. The telescopic length of the telescopic rod 41 is greater than half the height of the inflatable boat 2. The telescopic rod 41 is an electric or hydraulic telescopic rod, etc. The sliding frame 42 is slidably mounted on the transfer vehicle body 1 and obliquely penetrates the transfer vehicle body 1. The support wheel 44 is made of the same material as the roller 53.

[0021] When it is necessary to move the assault boat 2 onto the main body 1 of the transfer vehicle, the telescopic rod 41 is driven. The telescopic rod 41 extends and pushes the sliding frame 42 downward. The downward movement of the sliding frame 42 causes the support wheel 43 to contact the ground. The support wheel 43, the sliding frame 42, and the telescopic rod 41 support the rear of the main body 1 of the transfer vehicle. Then, the assault boat 2 is moved onto the main body 1 of the transfer vehicle. The telescopic rod 41 is then retracted. The telescopic rod 41 pulls the sliding frame 42 upward, pushing the support wheel 44 to follow. The support wheel 44 moves and contacts the rear of the assault boat 2, restricting the assault boat 2 from sliding to the rear. This facilitates the support of the main body 1 of the transfer vehicle and the rear of the assault boat 2, improving work efficiency.

[0022] A limiting mechanism 5 is provided on the main body 1 of the transfer vehicle on one side of the head of the assault boat 2. The limiting mechanism 5 is used to restrict the assault boat 2 from sliding towards the head side. The limiting mechanism 5 includes a fixed plate 51 on the main body 1 of the transfer vehicle. A guard arm 52 is rotatably connected to the side wall of the fixed plate 51. A roller 53 for rolling contact with the side wall of the assault boat 2 is rotatably connected to the end of the guard arm 52 away from the fixed plate 51. A screw 54 is threadedly connected to the fixed plate 51. A guard plate 55 for restricting the movement of the assault boat 2 towards the fixed plate 51 is rotatably connected to the end of the screw 54 near the assault boat 2. The width of the fixed plate 51 is smaller than the width of the assault boat 2. A winch can be installed on plate 51. A torsion spring is provided at the fixed plate 51 where the guard arm 52 is rotatably connected to the guard arm 52 to push the guard arm 52 closer to the side wall of the assault boat 2. One end of the torsion spring is connected to the guard arm 52, and the other end is connected to the fixed plate 51. The roller 53 is a rubber roller. Two sets of nuts can be set on the screw 54. The two sets of nuts are respectively on both sides of the fixed plate 51. Rotating the nuts threadedly connected to the screw 54 and pressing against the end face of the fixed plate 51 can restrict the movement of the screw 54 and the rotation of the guard plate 55. A rubber buffer layer is provided on the side wall of the guard plate 55 near the assault boat 2. The size of the guard plate 55 is smaller than the size of the fixed plate 51. The guard plate 55 has a disc-shaped structure.

[0023] When the assault boat 2 is pushed into the main body 1 of the transfer vehicle, the head of the assault boat 2 enters between the two sets of protective arms 52 and moves to contact the rollers 53. The rollers 53 push the two sets of protective arms 52 to unfold outward. At the same time as the protective arms 52 unfold, the torsion spring is stressed. Through the reaction force of the torsion spring, the rollers 53 press against the side wall of the head of the assault boat 2. The screw 54 is rotated, and the screw 54 is threaded to the fixing plate 51 and moves to one side of the assault boat 2. This pushes the protective plate 55 to press against the head of the assault boat 2, restricting the assault boat 2 from moving to one side of the head. The protective plate 55 and the two sets of rollers 53 provide multi-point support for the head of the assault boat 2, which can work with the support mechanism 4 to stably limit the movement of the assault boat 2.

[0024] Working principle: When it is necessary to move the inflatable boat 2 onto the main body 1 of the transfer vehicle, the telescopic rod 41 is driven. The telescopic rod 41 extends and pushes the sliding frame 42 downward. The downward movement of the sliding frame 42 causes the support wheel 43 to contact the ground. The support wheel 43, the sliding frame 42, and the telescopic rod 41 support the rear of the main body 1 of the transfer vehicle. Then, the inflatable boat 2 is moved onto the main body 1 of the transfer vehicle. The telescopic rod 41 is then retracted. The telescopic rod 41 pulls the sliding frame 42 upward, pushing the support wheel 44 to move upward as well. The support wheel 44 moves and contacts the rear of the inflatable boat 2, restricting the inflatable boat 2 from sliding to the rear, thus facilitating the support of the main body 1 of the transfer vehicle and the rear of the inflatable boat 2. This improves work efficiency. When the assault boat 2 is pushed into the main body 1 of the transfer vehicle, the head of the assault boat 2 enters between the two sets of guard arms 52 and moves to contact the rollers 53. The rollers 53 push the two sets of guard arms 52 to unfold outward. At the same time as the guard arms 52 unfold, the torsion spring is stressed. Through the reaction force of the torsion spring, the rollers 53 press against the side wall of the head of the assault boat 2. The screw 54 is rotated, and the screw 54 is threaded to the fixing plate 51 and moves to one side of the assault boat 2. This pushes the guard plate 55 to press against the head of the assault boat 2, restricting the assault boat 2 from moving to one side of the head. This allows the support mechanism 4 to stably limit the movement of the assault boat 2, enabling multi-point support for the head of the assault boat 2.

[0025] The telescopic rod 41 and the torsion spring are existing technologies and will not be described in detail here.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
