Technical Field
[0001] This utility model relates to the field of anti-roll technology for assault boats, and in particular to a cloth bag structure for anti-roll of assault boats. Background Technology
[0002] The assault boats are presented in three forms: fiberglass assault boats, inflatable rubber boats, and assault boats made of Hypalon material.
[0003] Existing inflatable boats use a bag structure with inflatable airbags added to the sides to balance the boat. However, when faced with the rapid impact of sudden wind and waves, the center of gravity is easily shifted, and the inflatable boat becomes unstable. Therefore, it is necessary to adjust the bag structure to achieve the adjustment of the center of gravity, so as to actively counteract the swaying. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag structure for reducing the roll of assault boats.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bag structure for reducing the roll of an assault boat includes an assault boat body and a mounting block. A bag body is fixedly mounted on the assault boat body. A fixing component is installed inside the mounting block. A sliding groove is formed on the assault boat body, and a slider is slidably connected in the sliding groove. A threaded rod is threaded through the slider. One end of the slider is fixedly mounted on the lower end of the mounting block. A control cavity is formed inside the assault boat body, and one end of the threaded rod is rotatably connected in the control cavity. A bevel gear is fixedly mounted on one end of the threaded rod. A rotary motor is fixedly mounted on the assault boat body, and a bevel gear is fixedly mounted on the motor shaft of the rotary motor. The bevel gear meshes with the bevel gear.
[0007] Preferably, the fixing component includes a placement groove on the mounting block, a counterweight block slidably connected in the placement groove, two mutually symmetrical limiting openings on the counterweight block, two mutually symmetrical openings on the placement groove, limiting blocks slidably connected in each of the two openings, the two limiting blocks slidably connected in the two limiting openings respectively, and screws threadedly connected to the two limiting blocks. A spur gear I is fixedly installed at one end of each screw. A rotating rod rotatably passes through the mounting block, and spur gear II is fixedly installed at both ends of each rotating rod. The two spur gear I gears mesh with the two spur gear II gears respectively.
[0008] Preferably, two symmetrical handles are fixedly installed on the main body of the assault boat. Both handles are fitted with rubber sleeves on their outer walls, and both handles are made of aluminum alloy.
[0009] Preferably, the rotary motor has a waterproof and corrosion-resistant housing.
[0010] Preferably, a knob is fixedly installed on one end of the rotating rod, and the knob is provided with anti-slip texture, which is installed in a strip shape.
[0011] Preferably, both openings are square-shaped and both limiting blocks are also square-shaped, with each limiting block matching one of the two openings.
[0012] 1. Compared with the prior art, the beneficial effects of this utility model are: the rotation of bevel gear one and bevel gear two driven by the rotary motor can drive the threaded rod to rotate, thereby adjusting the position of the slider on the assault boat, thereby driving the counterweight to change different positions to complete the adjustment of the center of gravity, thus effectively and actively counteracting the swaying.
[0013] 2. By rotating the lever and being driven by spur gear one and spur gear two, the limit block can be quickly installed and removed from the counterweight. This allows the weight of the counterweight to be changed according to the number of people on the inflatable boat before work begins, improving practicality and meeting the needs of the staff.

Detailed Implementation
[0018] Reference Figures 1-3A bag structure for reducing the roll of an assault boat includes an assault boat body 1 and a mounting block 2. Two symmetrical handles 19 are fixedly installed on the assault boat body 1. Rubber sleeves are fitted on the outer walls of both handles 19. The inner parts of both handles 19 are made of aluminum alloy. Through the handles 19, the staff can better stabilize themselves on the assault boat body 1. At the same time, the rubber sleeves can increase friction and make the grip more stable. The inner parts of the handles 19 are made of aluminum alloy to improve the strength of the handles 19. A bag body 3 is fixedly installed on the assault boat body 1. A fixing component is installed in the mounting block 2. The fixing component includes a placement groove 10 opened on the mounting block 2. A counterweight 11 is slidably connected in the placement groove 10. The counterweight 11 has two symmetrical limiting holes 12. The placement groove 10 has two symmetrical openings 13.
[0019] Each of the two openings 13 has a slidable limiting block 14. Both openings 13 are square in shape, and both limiting blocks 14 are also square in shape. The two limiting blocks 14 are matched with the two openings 13 respectively. Therefore, when the screw 15 rotates, the limiting blocks 14 can slide stably in the openings 13 without shaking. The two limiting blocks 14 are slidably connected to the two limiting ports 12 respectively. The screw 15 is threaded onto both limiting blocks 14. A spur gear 16 is fixedly installed at one end of the screw 15. A rotating rod 17 is rotatably inserted through the mounting block 2. A knob 20 is fixedly installed at one end of the rotating rod 17. The knob 20 is equipped with anti-slip texture. The anti-slip texture is installed in a strip shape. By rotating the knob 20, the operator can easily rotate the rotating rod 17 to complete the installation of the counterweight block 11.
[0020] Both ends of the rotating rod 17 are fixedly installed with spur gears 18. Two spur gears 16 mesh with the two spur gears 18 respectively. Through the above structure, when the knob 20 is rotated, the spur gears 18 are driven to rotate, which in turn drives the meshing spur gears 16 to rotate. The two screws 15 rotate, and the two limiting blocks 14 enter the two limiting ports 12 to install the counterweight block 11. The main body 1 of the assault boat has a sliding groove 4. A slider 5 is slidably connected in the sliding groove 4. A threaded rod 6 is threaded through the slider 5. One end of the slider 5 is fixedly installed at the lower end of the mounting block 2. The main body 1 of the assault boat has a control cavity. One end of the threaded rod 6 is rotatably connected in the control cavity. A bevel gear 7 is fixedly installed at one end of the threaded rod 6. A rotary motor 8 is fixedly installed on the main body 1 of the assault boat.
[0021] The rotary motor 8 is existing technology, which enables the object connected to its motor shaft to rotate. The rotary motor 8 adopts a waterproof and corrosion-resistant shell. The waterproof shell reduces the amount of water entering the rotary motor 8 and causing corrosion to its interior, thus effectively extending its service life. The motor shaft of the rotary motor 8 is fixedly mounted with a second bevel gear 9, which meshes with a first bevel gear 7. Through the above structure, the rotation of the second bevel gear 9 and the first bevel gear 7 drives the threaded rod 6 to rotate, which in turn drives the slider 5 to move. This allows the position of the counterweight 11 to be adjusted, thereby adjusting the center of gravity of the assault boat body 1.
[0022] In this invention, the working principle is as follows: Before starting work, the operator selects the counterweight 11 based on the number and weight of workers. The operator then takes out the counterweight 11 and places it into the placement slot 10. The operator then rotates the knob 20, causing the rotating rod 17 to rotate, which in turn rotates the two spur gears 18 simultaneously. This, in turn, rotates the two spur gears 16 simultaneously, which in turn rotates the two screws 15. This causes the two limiting blocks 14 to slide within the opening 13 and enter the limiting port 12 of the counterweight 11, completing the installation of the counterweight 11. During work, when the center of gravity needs adjustment, the rotating motor 8 is turned on. The rotating motor 8 drives the bevel gear 9 to rotate, which in turn drives the meshing bevel gear 7 to rotate, causing the fixedly installed threaded rod 6 to rotate. Therefore, the slider 5 slides within the sliding groove 4 and adjusts its position, thereby adjusting the position of the mounting block 2 and the counterweight 11 installed on it. This completes the adjustment of the center of gravity, meeting the operator's needs.
