Description

Technical Field

[0001] This utility model relates to the field of belt buckles, and more particularly to a belt buckle structure. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemicals, and steel for short-distance, small-volume transport. Plate conveyor belts are commonly used in the mining industry for transporting ore. Plate conveyors consist of individual belt panels spliced ​​together, which are then connected and secured together using belt clips.

[0003] Existing belt buckles mostly use nails to fix the belt in place. However, during long-term use of the conveyor belt, the nails can loosen due to bumps, causing the belt buckle to loosen. Therefore, we propose a belt buckle structure to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a belt buckle structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A belt buckle structure includes: a buckle body, two sliding holes are formed inside the top of the buckle body, a first insert block is slidably connected to the inner side of each of the two sliding holes, and a second insert block is movably inserted into the inner side of each of the two first insert blocks, and a plate is fixedly connected to the bottom of the buckle body, a fixed post is rotatably connected to the inner side of the plate, a first circular plate is fixedly connected to the top of the fixed post, two first posts are fixedly connected to the top of the first circular plate, a first connecting rod is rotatably connected to the outer side of each of the two first posts, and the other end of each of the two first connecting rods is rotatably connected to one side of a corresponding second insert block, and a small block is fixedly connected to the bottom of each of the two second insert blocks, and two sliding grooves adapted to the small blocks are formed on the top of the plate, and the outer sides of the two small blocks are slidably connected to the inner side of the corresponding sliding grooves.

[0012] In this utility model, a belt buckle structure is described. By placing the two belt blades of the plate belt inside the buckle body, the friction is enhanced due to the action of the protrusion, making the plate belt more stable. Furthermore, pressing down on the lever causes the spring to compress and the first insert to slide. As the user presses down, the first insert passes through the belt and is inserted into the rectangular hole. At this time, turning the handwheel causes the screw to rotate, which causes the first block to move horizontally, causing the second connecting rod to rotate.

[0013] In this utility model, the belt buckle structure starts to rotate by the second circular plate, which causes the first circular plate to start to move synchronously. Furthermore, the first connecting rod starts to rotate, which causes the first insert block to start to move horizontally and be inserted into the inner side of the first insert block. At this time, the bolt is inserted into the inner side of the corresponding insertion hole and the bolt is tightened on the connecting frame to complete the fixing of the belt.

[0014] This utility model has a reasonable structural design. Through the cooperation between the handwheel, screw, block number one, circular plate number one and circular plate number two, the buckle body can stably fix the two belt blades, thus facilitating the user's work.

A screw 11 is threadedly connected to the inner side of the first block 10. Two brackets are fixedly connected to the bottom of the plate 15. The inner side of each bracket is rotatably connected to the outer side of the screw 11. A connecting frame is fixedly connected to one side of the plate 15. A bolt 13 is threadedly connected to the inner side of the connecting frame. A handwheel 12 is provided at the bottom of the plate 15. Multiple insertion holes adapted to the bolts 13 are opened on one side of the handwheel 12. The outer side of the bolt 13 is movably inserted into the inner side of the corresponding insertion hole, which allows the position of the handwheel 12 to be fixed at this time.

[0022] In this embodiment, a spring 14 is fixedly connected to the top of the button body 1, and a lever 2 is fixedly connected to the other end of the spring 14. A first cylinder is fixedly connected to the bottom of the lever 2, and a first rod is slidably connected to the inner side of the first cylinder.
