[0002] Hexagonal head long thread bolts are mechanical fasteners with hexagonal heads. The head design facilitates tightening with wrenches or other tools. The longer threaded portion provides a larger contact area and stronger locking force, making them suitable for connections requiring longer threaded contact. They are commonly used in machinery, construction, and other fields, and are widely used to connect and fix various components, especially in applications requiring high strength and stability. The hexagonal head design facilitates operation and is commonly found in applications requiring high torque tightening.

[0030] 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.

[0031] Example 1:

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a hexagonal head long thread titanium alloy bolt, including a nut 1, a screw 2 fixedly connected to the bottom of the nut 1, a reinforcing component 3 installed inside the nut 1, an adapter component 4 provided on the top of the nut 1, and a hand-tightening component 5 installed on the top of the adapter component 4; the reinforcing component 3 includes a sliding block 6, which is slidably connected inside the nut 1, causing the sliding block 6 to move outward and press against a wrench, increasing the friction between the wrench and the nut 1; a limiting plate 7 is fixedly connected to the side of the sliding block 6, and a sliding post 8 is fixedly connected to the side of the limiting plate 7; a baffle 9 is slidably connected to the outside of the sliding post 8, and the baffle 9 is fixedly connected inside the nut 1; by moving the limiting plate 7 and the sliding post 8, the movement of the sliding block 6 is controlled. A pressure spring 10 is sleeved on the outer periphery of the sliding post 8, and the pressure spring 10 is located between the baffle 9 and the limiting plate 7; the pressure generated by the cooperation of the pressure spring 10 and the baffle 9 causes the sliding block 6 to be forced and move outward.

[0033] Reference Figure 1 The adapter component 4 includes a hex head 401, which is fixedly connected to the top of the nut 1. The diameter of the hex head 401 is smaller than the diameter of the nut 1. By using nuts 1 and hex heads 401 of different diameters, different types of tools can be adapted to improve the compatibility of bolts.

[0034] Reference Figure 1 and Figure 3 The hand-tightening assembly 5 includes a hand-tightening plate 12, which is rotatably connected to the top of the adapter assembly 4. A support block 13 is fixedly connected to the top of the adapter assembly 4, and the hand-tightening plate 12 is rotatably connected to the outside of the support block 13. By setting the support block 13, support force is provided when the hand-tightening plate 12 is rotated. A spherical locking block 14 is provided on the top of the adapter assembly 4, and a locking groove 15 is opened on the side of the hand-tightening plate 12. The spherical locking block 14 and the locking groove 15 engage with each other, and the position of the hand-tightening plate 12 is fixed by the cooperation of the spherical locking block 14 and the locking groove 15.

[0035] Reference Figure 1 and Figure 2 The nut 1 has a groove 11 inside, and the limiting plate 7 is slidably connected inside the groove 11. Through the cooperation of the limiting plate 7 and the groove 11, the sliding block 6 is prevented from being squeezed out of the nut 1. The nut 1, screw 2 and adapter component 4 are all made of titanium alloy, which has excellent corrosion resistance, strength and lightweight characteristics.

[0036] Example 2:

[0037] Reference Figure 1 In contrast to the above embodiments, this utility model also provides an embodiment in which the adapter component 4 includes a hexagonal head 401 and a hexagonal head 402. The hexagonal head 402 is fixedly connected to the top of the nut 1, and the hexagonal head 401 is fixedly connected to the top of the hexagonal head 402. The diameter of the hexagonal head 402 is smaller than the diameter of the nut 1, and the diameter of the hexagonal head 401 is smaller than the diameter of the hexagonal head 402. By using nuts 1, hexagonal heads 401 and hexagonal heads 402 of different diameters, different types of tools can be adapted, thereby improving the compatibility of bolts.

[0038] Working principle: The wrench is locked on the outside of the nut 1. The pressure generated by the baffle 9 and the pressure spring 10 causes the sliding block 6 to move outward, squeezing the wrench and increasing the friction between the wrench and the nut 1, thus preventing the wrench from falling off the nut 1 and affecting the tightening work.

[0039] Hex head 1 (401) and hex head 2 (402) are provided on the top of nut 1. The diameters of nut 1, hex head 1 (401), and hex head 2 (402) are different to match different types of tools, thus improving the compatibility of this bolt.

[0040] When no suitable tools are available, the hand-tightening plate 12 is rotated out of the spherical locking block 14. With the support of the support block 13, the hand-tightening plate 12 is rotated to tighten and loosen the bolts. After the work is completed, the hand-tightening plate 12 is rotated so that the spherical locking block 14 is inserted into the slot 15 to fix the position of the hand-tightening plate 12, thereby improving the convenience of tightening and loosening the bolts.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
