[0020] like Figures 1 to 7As shown, a combined firm anti-loosening fastener comprises a nut main body structure 1 with a regular hexagonal cross section, wherein the interior of the nut main body structure 1 is provided with a full-through main body fastening connection threaded hole 3, and the overall fastening connection is performed through this position when in use. The upper end of the nut main body structure 1 is provided with an integrally formed cylindrical reinforcing isolation support column 2, which on the one hand improves the overall structural strength, and on the other hand can replace the washer at the fastening position for use, and has the function of fastening and isolation. The upper side of the reinforcing isolation support column 2 is an arc-shaped structural surface, which makes the space occupied by the outer position smaller. The main body fastening connection threaded hole 3 passes through the upper end of the reinforcing isolation support column 2, and the upper end position of the main body fastening connection threaded hole 3 is provided with a cylindrical anti-loosening matching sealing groove 4, which can be set in conjunction with the anti-loosening glue after fastening when fastening, so that the matching connection space of the anti-loosening glue is larger and the overall anti-loosening firmness is better. The side of the anti-loosening fitting sealing groove 4 is provided with an anti-loosening glue filling auxiliary groove 5 that passes through the outer side of the reinforced isolation support column 2, which is more convenient when filling the anti-loosening glue. The inner side of the anti-loosening glue filling auxiliary groove 5 is provided with a guide slope structure at a position that communicates with the anti-loosening fitting sealing groove 4, which makes the filling and fitting smoother and the filling efficiency higher. By arranging a reinforced isolation structure on the main structure of the nut, it can ensure that there is a larger structural space on the nut. By arranging a separate anti-loosening fitting sealing groove and auxiliary structure at the fastening position, it can facilitate the filling operation of the anti-loosening glue, and can ensure that the anti-loosening fitting space at the fastening position of the nut is larger, the overall anti-loosening effect is better, the connection is more reliable, and the safety is higher in later use.
[0021] Preferably, the size of the outer side of the reinforced isolation support column 2 is smaller than the size of the upper end face of the nut main body structure 1, so that the space occupied by the overall structure is relatively smaller and it is more convenient to install and match.
[0022] Preferably, the diameter of the reinforced isolation support column 2 is the same as the diameter of the inscribed circle of the upper end surface of the nut main body structure 1, so that the support strength of the upper end structure is higher when matched, and the overall structural strength can also reach the maximum.
[0023] Preferably, a glue-fitting stabilizing groove evenly distributed around the circumference is provided at the outer side of the anti-loosening fitting sealing groove 4, and the depth of the glue-fitting stabilizing groove is the same as the depth of the anti-loosening fitting sealing groove 4, so that the glue-fitting position has a larger space, and the fastening and anti-loosening position can form an anti-loosening effect with staggered distribution, so that the overall fastening and anti-loosening firmness can be further improved.
[0024] Preferably, the depth of the anti-loosening glue filling auxiliary groove 5 is less than half the depth of the anti-loosening fitting sealing groove 4, ensuring that there is more space for the internal anti-loosening glue fitting position, and this structure has less impact on the strength of the main structure.
[0025] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
