[0021] Such as Figures 1 to 7As shown in the figure, a stainless steel anti-loosening grooved bolt includes a bolt main body fastening seat 1 with a regular hexagon cross-section. At the upper end of the bolt main body fastening seat 1, there is a cylindrical bolt main body connecting rod 2. On the outer cylindrical surface of the bolt main body connecting rod 2, there is an overall fastening thread groove. On the outer cylindrical surface of the bolt main body connecting rod 2, there is an installation and cooperation grooved opening 3 that opens upward and completely penetrates the outer cylindrical surface in the front-back direction. At the front and rear edge positions of the installation and cooperation grooved opening 3, there are respectively provided cooperation placement guiding rounded corners 4, which makes the operation during combination more convenient and can play a role in cooperation guiding. On the left and right side end faces inside the installation and cooperation grooved opening 3, there are respectively provided arc-shaped anti-loosening combination stable grooves 5. When installed and used, anti-loosening glue can be set at this position, so that the cooperation position has a reliable anti-loosening cooperation effect after overall fastening. At the lower end of the installation and cooperation grooved opening 3, there is an arc-shaped second anti-loosening cooperation groove 6 that intersects with the bolt main body fastening seat 1. On the inner cylindrical surface of the second anti-loosening cooperation groove 6, there is an arc-shaped second anti-loosening safety groove 7. They can ensure a larger internal space during installation and can make anti-loosening glue be set deep inside, making the anti-loosening stability during connection and cooperation better, the overall connection strength more reliable, and capable of meeting the cooperation requirements of fastening positions with relatively high strength connection requirements. The central axis of the second anti-loosening safety groove 7 is parallel to the central axis of the second anti-loosening cooperation groove 6, which is more convenient for production and processing and has a lower production cost. By setting guiding rounded corners at the grooved opening position of the grooved bolt, it ensures that the combination operation during cooperation placement is more convenient. And at the central position of the grooved structure, there are two symmetrically distributed arc-shaped anti-loosening combination stable grooves. When installed, anti-loosening glue can be set inside this structure. When overall fastening is carried out, it can ensure a better fastening and anti-loosening effect. Through the setting of a second anti-loosening structure inside its main body structure, it can achieve the overall anti-loosening cooperation of the fastening position, with more reliable connection firmness, stronger durability, and higher anti-loosening safety during later use.
[0022] Preferably, the anti-loosening combination stable groove 5 is located at the central position in the width direction of the installation and cooperation grooved opening 3, so that the overall fastening and anti-loosening cooperation strength is better, the service life during later use is longer, and the anti-loosening effect is more stable.
[0023] Preferably, the inner cylindrical surfaces of the two anti-loosening combination stable grooves 5 are on the cylindrical surface of the same diameter, which makes the production and processing operation of this structure more convenient during production and processing and has higher position accuracy.
[0024] Preferably, the length of the anti-loosening combination stable groove 5 is greater than half of the length of the installation and cooperation grooved opening 3, which has less influence on the strength of the main body structure and the anti-loosening stability is also relatively reliable.
[0025] Preferably, the width of the second anti-loosening mating groove 6 is the same as that of the installation mating groove 3, which makes the flatness of the main body grooving position better and the processing efficiency higher.
[0026] Preferably, the central axis of the second anti-loosening mating groove 6 is on the upper end surface of the bolt body fastening seat 1, which makes the structural bearing strength of the mating position higher and the mating safety more reliable during use.
[0027] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or replacements can be made, and these improvements or replacements should also be regarded as the protection scope of the present invention.
