Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and more specifically, to a fastening anti-slip high-strength bolt. Background Technology

[0002] Threaded connections are a common type of fastening connection in the mechanical field. However, after long-term use, the fastening characteristics between bolts and nuts will decrease. Under vibration, impact or torsion, the bolt and nut may rotate relative to each other, which may cause the fastened object to shift and loosen. Therefore, the anti-loosening and anti-slip performance of bolts is particularly important.

[0003] In existing technologies, when treating bolts for slip resistance, glue is applied to the bolts, then the nuts are tightened. After the glue dries, the bolts and nuts are fixed together, thus achieving slip resistance. However, this method has some problems. When using bolts to connect parts, a large number of bolts are usually needed. To facilitate installation, the nuts are not tightened initially. They are tightened only after all bolts are installed. If glue is applied to the bolts first, it may have dried by the time all bolts are installed, making it inconvenient to connect the bolts and nuts. If glue is applied after all bolts are installed, it can only be applied to the outer side, resulting in fewer connection points and poor slip resistance. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the inconvenience of applying glue to nuts and bolts directly affects the anti-slip effect, and to design a high-strength bolt for fastening and anti-slip.

[0005] To achieve the above objectives, the technical solution of this utility model is a fastening anti-slip high-strength bolt, comprising a bolt body, an external thread on the outer side of the bolt body, storage grooves on both sides of the bolt body, a storage bag placed in the storage groove, an adhesive placed inside the storage bag, fixing rods installed at both ends of the storage bag, and a limit nut connected to the outer side of the bolt body by a thread. After the bolt body is fastened, the limit nut can squeeze the storage bag through the fixing rods to allow the adhesive to flow out.

[0006] Furthermore, the limiting nut includes a first nut that is threadedly connected to the bolt body. A flat washer fitted on the outside of the bolt body is provided on one side of the first nut. Push plates are integrally formed on both sides of the flat washer. The push plates can extend into the storage trough. A second nut that is threadedly connected to the bolt body is provided on one side of the flat washer. An adjusting block is provided on the bolt body. The adjusting block can adjust the position of the first nut so that the first nut is located outside the storage bag after being fixed.

[0007] Furthermore, the adjusting block is located on a plurality of circular washers fitted on the outside of the bolt body.

[0008] The beneficial effects of this utility model are as follows: When a storage bag is placed in the storage trough, the storage bag will be squeezed to break when the limiting nut is tightened on the bolt body. At this time, the adhesive in the storage bag can flow to the thread between the limiting nut and the bolt body. After the adhesive dries, the nut and bolt can be fixed, which can achieve a better anti-slip effect and extend the service life. Attached Figure Description

[0014] This utility model provides, for example Figure 1-2The bolt shown is a fastening anti-slip high-strength bolt, including a bolt body 1. The bolt body 1 has external threads on the outside. There are material storage grooves 2 on both sides of the bolt body 1. Material storage bags 3 are placed in the material storage grooves 2. The material storage bags 3 contain adhesive. Fixing rods 4 are installed at both ends of the material storage bags 3. Limiting nuts 5 are connected to the outside of the bolt body 1 by threads. After the bolt body 1 is fastened, the limiting nuts 5 can squeeze the material storage bags 3 through the fixing rods 4 to make the adhesive flow out.

[0015] The anti-slip process for this bolt is as follows: First, pass the bolt body 1 between the two parts, then put the storage bag 3 into the storage trough 2, and then screw the limiting nut 5 onto the bolt body 1. After tightening the limiting nut 5, the storage bag 3 can be squeezed open, allowing the adhesive to flow to the thread between the limiting nut 5 and the bolt body 1.
