Description

Technical Field

[0001] This utility model belongs to the field of bolt technology, and in particular relates to a high-strength bolt structure. Background Technology

[0002] High-strength bolts refer to bolts made of high-strength steel or bolts that require a large preload, emphasizing the design principle of transferring loads through friction.

[0003] The high-strength bolt structures currently available on the market have the following problems when applied:

[0004] 1. When using traditional high-strength bolt structures, installation usually requires workers to manually screw the high-strength bolts into the positions to be fixed. Because the bolt heads at the top are small, it is generally difficult to exert force when tightening, making them inconvenient to hold.

[0005] 2. Traditional high-strength bolt structures are generally tightened directly during use. However, they are prone to loosening over time or rotating under external force, resulting in poor fixing effect. Utility Model Content

[0006] The purpose of this utility model is to provide a high-strength bolt structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A high-strength bolt structure includes a threaded rod and a bolt head. A slot is formed on the surface of the bolt head, and a placement groove is formed on the surface of the bolt head. A pull rod is embedded inside the slot. A rotating plate is fixedly connected to the side of the pull rod. Two rotating plates are provided. A fixing block is fixedly connected to the bottom of the pull rod. The fixing blocks are symmetrically distributed.

[0008] Preferably, the bolt head is fixedly connected to a side plate, and there are two side plates. An internal thread seat is fixedly connected to the surface of the side plate, and a lead screw passes through the internal thread seat. A movable plate is provided at the bottom of the lead screw, an adhesive plate is provided at the bottom of the movable plate, and a turntable is provided at the bottom of the lead screw.

[0009] Preferably, a handle is fixedly connected to the top of the pull rod, and the handle is rectangular in shape.

[0010] Preferably, the fixing block is fixedly connected to the side of the fixing block, the slot is provided with a slot on the side, and the slot is embedded in the slot.

[0011] Preferably, a handle is fixedly connected to the top of the lead screw, and the number of handles is two.

[0012] Preferably, a guide rod is fixedly connected to the surface of the movable plate, and the guide rod is inserted inside the side plate.

[0013] The high-strength bolt structure of this utility model has the following advantages:

[0014] 1. This high-strength bolt structure features a slot and a placement groove on the bolt head surface. A pull rod is embedded inside the slot, a rotating plate is mounted on the side of the pull rod, and a fixing block is installed at the bottom of the pull rod. When the bolt structure needs to be installed in the required hole, the rotating rod is pulled directly to pull it out from the placement groove. The fixing block then secures it to the top of the bolt head. After pulling it out, the rotating plate can be held to rotate the bolt for initial fixation. After initial fixation, the pull rod can be pushed back to its original position, making it convenient for workers to hold the bolt head.

[0015] 2. This high-strength bolt structure features a side plate mounted on the side of the bolt head, an internal threaded seat mounted on the surface of the side plate, a threaded rod penetrating the internal threaded seat, a movable plate at the bottom of the threaded rod, an adhesive plate at the bottom of the movable plate, and a turntable at the bottom of the threaded rod. After the bolt structure is installed, the threaded rod can be rotated, causing it to rotate inside the internal threaded seat. This causes the movable plate to move downwards, bringing the adhesive plate into contact with the mounting surface, thus fixing the threaded rod and preventing it from loosening under external force, resulting in higher connection strength.

[0027] To better understand the purpose, structure, and function of this utility model, a high-strength bolt structure of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, this utility model discloses a high-strength bolt structure, including a threaded rod 1 and a bolt head 2. A slot 15 and a placement groove 11 are formed on the surface of the bolt head 2. A pull rod 13 is embedded inside the slot 15. A rotating plate 14 is fixedly connected to the side of the pull rod 13. Two rotating plates 14 are provided. A fixing block 17 is fixedly connected to the bottom of the pull rod 13. The fixing blocks 17 are symmetrically distributed. By creating the slot 15 and placement groove 11 on the surface of the bolt head 2, embedding the pull rod 13 inside the slot 15, installing the rotating plate 14 on the side of the pull rod 13, and installing the fixing block 17 at the bottom of the pull rod 13, when the bolt structure needs to be installed in the required hole, the rotating rod is pulled directly to pull it out from the placement groove 11. The fixing block 17 then fixes it to the top of the bolt head 2. After pulling it out, the rotating plate 14 can be held to rotate the bolt for initial fixation. After initial fixation, the pull rod 13 can be pushed back to its original position, making it convenient for workers to hold the bolt head 2.

[0029] Side plates 5 are fixedly connected to the side of the bolt head 2. There are two side plates 5. An internal thread seat 10 is fixedly connected to the surface of the side plate 5. A threaded rod 6 passes through the internal thread seat 10. A movable plate 3 is provided at the bottom of the threaded rod 6. An adhesive plate 4 is provided at the bottom of the movable plate 3. A turntable 7 is provided at the bottom of the threaded rod 6. By installing side plates 5 on the side of the bolt head 2, installing internal thread seats 10 on the surface of the side plates 5, passing through the internal thread seat 10, and adding movable plates 3 and adhesive plates 4 at the bottom of the movable plate 3, and adding turntable 7 at the bottom of the threaded rod 6, after the bolt structure is installed, the threaded rod 6 can be rotated, causing the threaded rod 6 to rotate inside the internal thread seat 10. At this time, the threaded rod 6 drives the movable plate 3 to move downward, so that the adhesive plate 4 and the mounting surface come into contact with each other. This fixes the threaded rod 1, preventing it from loosening under external force, and making its connection strength higher.

[0030] A handle 12 is fixedly connected to the top of the pull rod 13. The handle 12 is rectangular in shape. By installing the handle 12 on the top of the pull rod 13, the pull rod 13 can be easily pulled out by holding the handle 12.

[0031] The fixing block 17 is fixedly connected to the side of the card block 18, and the slot 15 has a slot 16 on its side. The card block 18 is embedded in the slot 16. By installing the card block 18 on the side of the fixing block 17 and the slot 16 on the side of the slot 15, the pull rod 13 can be fixed by embedding the card block 18 in the slot 16.

[0032] A handle 9 is fixedly connected to the top of the lead screw 6. There are two handles 9. By installing handles 9 on the top of the lead screw 6, the lead screw 6 can be easily rotated by holding the handles 9.

[0033] A guide rod 8 is fixedly connected to the surface of the movable plate 3. The guide rod 8 is inserted inside the side plate 5. By installing the guide rod 8 on the surface of the movable plate 3, the rotation of the movable plate 3 when it moves downward can be prevented.

[0034] The working principle of this high-strength bolt structure is as follows: When using this bolt structure, hold the handle 12 and pull its rotating rod to pull it out from the placement groove 11. Fix it to the top of the bolt head 2 through the fixing block 17. Insert the locking block 18 into the locking groove 16 to fix the pulling rod 13. After pulling it out, hold the rotating plate 14 to rotate the bolt for initial fixation. After initial fixation, simply push the pulling rod 13 back to its original position for easy gripping of the bolt head 2. After the bolt structure is installed, hold the handle 9 and rotate the screw 6 so that the screw 6 rotates inside the internal thread seat 10. At this time, the screw 6 drives the moving plate 3 to move downward. The guide rod 8 can prevent the moving plate 3 from rotating when moving downward, so that the adhesive plate 4 and the mounting surface come into contact with each other. At this time, the threaded rod 1 can be fixed to prevent it from loosening under external force, thus making its connection strength higher.
