[0002] This new type of corrosion-resistant fiberglass bolt is made of high-quality fiberglass. It boasts excellent corrosion resistance, enabling long-term use in harsh environments such as acids and alkalis. It is also high-strength, lightweight, and easy to install, effectively reducing project costs. Furthermore, it is environmentally friendly and pollution-free, making it widely applicable in chemical, marine engineering, and other fields, and an ideal fastener.

[0003] In the existing technology, when a new type of corrosion-resistant fiberglass bolt is damaged during the loosening process and cannot be turned, there is a lack of alternative mechanisms to turn the bolt head. This makes it difficult to remove the entire bolt and separate the connected parts for subsequent maintenance, replacement or debugging, which seriously affects the normal operation and maintenance progress of the equipment or project, and increases the overall downtime and operation and maintenance costs.

[0004] To address the above problems, a new type of corrosion-resistant fiberglass bolt is proposed. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] One embodiment of this utility model is a novel corrosion-resistant fiberglass bolt, comprising a stud 4, a knob assembly provided on the outside of the stud 4, a nut 5 threadedly connected to the outside of the stud 4, and an anti-loosening component provided inside the nut 5.

[0033] The knob assembly includes a nut 1, which is fixedly connected to the outside of a stud 4. A slot 2 is formed inside the nut 1, and two spare slots 3 are formed inside the nut 1.

[0034] Specifically, stud 4 serves as the main connecting support, penetrating the connected object and providing a threaded mating base for nut 5. The knob assembly facilitates bolt installation and removal. If hexagonal bolt 1 becomes unusable due to wear, deformation, or other reasons, other tools can be used for tightening, providing a backup operating method to ensure smooth bolt operation under various conditions. Nut 5, through its threaded connection with stud 4, secures the connected objects together, and its internal anti-loosening component effectively prevents loosening due to vibration, external forces, or other factors during use, ensuring the stability and reliability of the connection.

[0035] Reference Figure 1 - Figure 4 The anti-loosening component includes a second gasket 9 and a first gasket 6. Both the second gasket 9 and the first gasket 6 are sleeved on the outside of the stud 4. Two plug-in blocks 7 are fixedly connected to one side of the first gasket 6. Multiple gasket patterns 3 11 are provided on the other side of the first gasket 6. Multiple gasket patterns 1 8 are provided on one side of the second gasket 9. Multiple gasket patterns 2 10 are provided on the other side of the second gasket 9.

[0036] Specifically, washer 2 (9) and washer 1 (6) are both fitted on the outside of stud 4 to assist in preventing loosening of nut 5 and increase connection stability. The plug block 7 is designed to cooperate with the two plug slots 12 inside nut 5. When nut 5 is tightened, plug block 7 is inserted into the plug slots 12. Washer pattern 3 (11) and washer pattern 1 (8) cooperate with each other. Since they are matched and both are trapezoidal in shape, these patterns interlock during the tightening of nut 5, which increases the friction between the washer, nut 5, and the connecting surface, effectively preventing nut 5 from loosening due to vibration or other reasons. Washer pattern 2 (10) also participates in the contact and friction with the connecting surface, further strengthening the anti-loosening effect of the entire anti-loosening component on nut 5, ensuring that the new type of corrosion-resistant fiberglass bolt can maintain the reliability and stability of the connection under various working conditions.

[0037] Reference Figure 1 - Figure 4 Washer pattern 18, washer pattern 29 and washer pattern 210 are integrally formed structures, washer pattern 16 and washer pattern 31 are integrally formed structures, the protrusions of washer pattern 31, washer pattern 18 and washer pattern 210 are all trapezoidal in shape, washer pattern 18 and washer pattern 311 are matched with each other, nut 5 has two insertion slots 12 inside, insertion block 7 is inserted into the insertion slot 12 on the outside, the groove depth of slot 2 is greater than the groove depth of spare slot 3, slot 2 is connected to spare slot 3.

[0038] Specifically, gasket pattern 18, gasket pattern 29, and gasket pattern 210 are integrally molded structures, as are gasket pattern 16 and gasket pattern 311. This ensures the integrity and stability of the structure, reducing the possibility of loosening due to loose component connections. The protrusions of gasket pattern 311, gasket pattern 18, and gasket pattern 210 are all trapezoidal in shape and match each other. When nut 5 is tightened, the mutual compression and interlocking of the trapezoidal protrusions greatly increases the friction between the gasket and nut 5, and the connecting surface, effectively resisting the tendency of nut 5 to loosen due to vibration, external impact, etc., and ensuring the bolt... The connection is secure. The insertion slot 12 and the insertion block 7 are used to rotate the washers 6 and 8 together when tightening the nut 5. The slot depth of the slot 2 is greater than that of the spare slot 3 and the two are connected. The slot 2 is used to facilitate the user to tighten the nut 1 with a flathead knife under normal conditions. Its deeper slot can better fit the tool and transmit torque. The spare slot 3, in conjunction with the slot 2, can be tightened with a Phillips head knife, providing another way to tighten the nut 1. This ensures that the bolt can be tightened or loosened smoothly under different conditions, improving the reliability and flexibility of bolt use.

[0039] Working principle: During installation, the stud 4, which is fixedly connected to the outside of the nut, can be placed in the corresponding installation position. Then, the nut 5 is threaded onto the outside of the stud 4. If the hexagonal nut 1 is damaged during the loosening process and cannot be turned, a slot 2 is opened inside the nut 1. A suitable flathead screwdriver can be inserted into the slot 2 to turn it. At the same time, there are two spare slots 3 inside the nut 1. The spare slots 3 and the slot 2 can be used together to turn it with a Phillips screwdriver.

[0040] An anti-loosening component is provided inside the nut 5. Washers 1 (6) and 2 (9) in the anti-loosening component are both fitted onto the outside of the stud 4. Washers 1 (6) and 2 (9) each have different washer patterns, and washer patterns 1, 2 (9), and 2 (1) are integrally formed. Washer 1 (6) and washer pattern 3 (11) are also integrally formed. The protrusions of these washer patterns are all trapezoidal in shape, and washer patterns 1 (8) and 3 (11) match each other, effectively preventing relative rotation of washers 1 (6) and 2 (9), and locking the connector 7 in place. In the insertion slot 12 of the nut 5, when the nut 5 is being tightened, the insertion block 7 rotates with the nut 5. After the nut 5 is tightened, the insertion block 7 of the washer 6 limits the nut 5 to prevent it from loosening. After the torque is reached, the washer pattern 10 of the washer 9 applies pressure to the workpiece. These washer patterns cooperate with each other, effectively increasing the friction between the washer and the nut 5 and the connecting surface after the nut 5 is tightened, preventing the nut 5 from loosening due to vibration or other reasons, thereby ensuring the stability of the entire bolt connection structure.

[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.
