[0004] The technical solution of the utility model is as follows:

[0005] A novel connecting bolt fixing structure comprises a loading bolt and a bottom cover, wherein the rear of the loading bolt and the bottom cover are connected by threads, thread anaerobic adhesive is applied to the threads on the inner wall of the front of the loading bolt, a mounting rod is connected to the threads, and a loading nut and an anti-vibration buffer block are sleeved on the mounting rod from left to right.

[0006] The threaded tail end is fixed with a retaining ring, the retaining ring is provided with a notch, a retaining ring groove is provided on the retaining ring, and a sealing ring b is provided in the retaining ring groove.

[0007] Anti-vibration pads are arranged at both ends of the anti-vibration buffer block.

[0008] A sealing ring a is provided at the contact point between the inner wall of the rear part of the loading bolt and the outer wall of the bottom cover.

[0009] The side wall of the loading bolt is provided with a mounting opening, and the mounting opening is provided with a step b.

[0010] A step a is provided at the opening of the inner wall of the front portion of the loading bolt.

[0011] The technical solution of the utility model has a novel structure and an ingenious and simple design. A retaining spring is provided at step a, and a retaining spring groove is designed with a notch, which is convenient for rework and reduces processing costs. The utility model has a beautiful appearance, and anaerobic glue is applied to reinforce the thread to prevent the loading bolts from loosening. A retaining spring design is added to the tail end of the connection, which has a double-layer insurance and increases the tensile strength of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the utility model;

[0013] Figure 2 , 3 4 is a schematic diagram of the structure of the mounting bolt of the utility model. DETAILED DESCRIPTION

[0015] Example

[0016] like Figure 1 , 2 A new type of connecting bolt fixing structure shown in , 3 and 4 includes a loading bolt 2 and a bottom cover 1, wherein the rear portion of the loading bolt 2 and the bottom cover 1 are connected by threads, threaded anaerobic adhesive is applied to the threaded portion of the inner wall of the front portion of the loading bolt 2, a mounting rod 7 is connected to the threaded portion, and a loading nut 6 and an anti-vibration buffer block 4 are sleeved on the mounting rod 7 from left to right.

[0017] The threaded tail end is fixed with a retaining ring 3, the retaining ring 3 is provided with a notch, the retaining ring 3 is provided with a retaining ring groove, and the retaining ring groove is provided with a sealing ring b.

[0018] Anti-vibration pads 5 are provided at both ends of the anti-vibration buffer block 4 .

[0019] A sealing ring a is provided at the contact point between the rear inner wall of the loading bolt 2 and the outer wall of the bottom cover 1 .

[0020] The side wall of the loading bolt 2 is provided with a mounting opening, and the mounting opening is provided with a step b.

[0021] A step a is provided at the opening of the front inner wall of the loading bolt 2.

[0022] When in use, a retaining spring 3 is provided at step a, and a retaining spring groove is designed with a notch for easy rework. Anaerobic glue is applied to reinforce the thread to prevent the loading bolt 2 from loosening. A retaining spring design is added to the tail end of the connection, which provides double-layer insurance and increases the tensile strength of the structure.
