Description

Technical Field

[0001] The utility model relates to the technical field of turnbuckle bolts, in particular to a turnbuckle bolt capable of multi-point traction. Background Art

[0002] LNG ship refers to a "ship" that is specially used to transport liquefied natural gas. Liquefied natural gas is stored in the cargo tank of the LNG ship. In order to ensure the insulation isolation between the cargo tank and the liquefied natural gas, it is necessary to lay insulating boards in the cargo tank. During the laying of the insulating boards, it is necessary to use a basket screw to adjust the distance between adjacent insulating boards. The two connecting plates of the basket screw are fixed to the two insulating boards respectively. The gap between the insulating boards is adjusted by the basket screw so that the insulating boards are pulled closer to each other and fixed into a stable whole, thereby realizing the splicing and fixation between the insulating boards. At the same time, the basket screw is also used for the fixed connection between the insulating boards and other components;

[0003] The existing basket screw has a simple structure, and two objects are pulled and fixed by two symmetrically arranged traction plates. It has poor adjustability and a small traction area, which will cause the insulating plate to be locally subjected to a large traction force, resulting in poor traction effect. In addition, the traction and fixing position cannot be changed according to the actual structure and construction requirements of the pulled object. The scope of application is limited and it cannot meet the use requirements of various working conditions. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a multi-point towable basket bolt, which can pull and fix the insulating board over a large area and at multiple points, so that the basket screw can more stably adjust the distance between the two insulating boards, and can freely choose the fixed connection with different positions of the insulating board according to the actual structure or construction needs, with a wide range of applications and strong practicality.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0032] In actual use, the slider 12 slides on the surface of the adjustment plate 4 toward the end plate 3. During the sliding process of the slider 12, the connecting rod 6 is pushed to swing, so that the two first swing plates 5 rotatably connected to the two connecting rods 6 are opened at the same time, so that the first swing plates 5 drive the second swing rod 7 to swing. According to actual needs, the two first swing plates 5 can be swung to both sides at a certain angle, so that the second swing rod 7 can be fixedly connected to different points of the insulating plate, thereby expanding the traction area of ​​the insulating plate, so that the basket screw can more stably adjust the distance between the two insulating plates, and the adjustment is more convenient. Convenience; by controlling the rotational connection between the second swing arm 7 and the first swing plate 5 through the locking assembly, the second swing arm 7 can be freely selected to be fixedly connected to different positions of the insulating board according to the actual structure or construction needs. The bottom surface of the second swing arm 7 is tightly fitted with the surface of the insulating board, and the end plate 3 and the adjustment frame 1 are not in contact with the surface of the insulating board. The second swing arm 7 is fixedly connected to the insulating board through the mounting hole 8, and the adjustment frame 1 is screwed. By utilizing the threaded connection between the adjustment frame 1 and the threaded adjustment rod 2, the two threaded adjustment rods 2 will be close to each other, thereby realizing large-area, multi-point pulling and fixing of the two insulating boards.
