In particular, the ring 2 is an annular cylinder with a through hole in the middle, generally in the shape of a circle. At least one surface of the ring 2 is provided with a circle of groove, the groove is filled with the glue 3, and the surface opening of the groove is in adhesive bonding or hot melting fusion sealing connection through the plastic film 4. The groove to be connected in a sealing manner is the annular groove 21, and the annular groove 21 is positioned inside the ring 2 or is connected with the ring 2. Wherein, glue 3 can be filled in the recess through full-automatic point gum machine. The metal ring 22 is an annular cylinder with a through hole in the middle, and the metal ring 22 is made of metal material. The metal ring 22 is located outside or inside the ring 2, and may be embedded inside the ring 2 to provide an additional supporting force for the ring 2 made of plastic material, so as to compensate for the reduction of the supporting force caused by the ring 2 provided with the annular groove 21. Of course, the ring 2 can also be increased in thickness and strength to ensure sufficient support and connection. If necessary, a plurality of metal loops 22 are provided on the outer side, inner side, and inner side of the loop 2. The metal ring 22 is connected and fixed with the ring 2 made of a solid material in a gluing mode, or a clamping mode or a sleeving mode. The metal ring 22 is a hard ring 2 made of a hard material having a relatively high hardness, and includes: ABS engineering plastics, ceramics, toughened glass and metal materials.
The bolt is connected with the nut 1, and the external thread of the bolt penetrates through the internal thread of the nut 1 in a rotating mode. The outer thread of the bolt presses the inner wall of the annular groove 21 in the ring 2 to break the inner wall of the annular groove 21, or the plastic film 4 is broken by pressing and stretching to make the glue 3 stored in the annular groove 21 flow out to the surface of the outer thread. And a spiral indentation or groove is formed in the rotary extrusion process of the external thread of the bolt and the inner wall of the ring 2. Meanwhile, the glue 3 on the surface of the external thread is coated on the surface of the indentation or groove on the inner wall of the ring 2 in the rotating process. Between the metal external thread on the screw rod in the bolt and the inner wall made of nylon plastic in the nut 1, on the basis of the anti-loose connection through large friction force, the external thread of the bolt and the inner wall surface of the ring 2 form adhesive connection, so that the permanent anti-loose effect is achieved. The thickness of the inner wall of the annular groove 21 on the surface contacting with the external thread in the bolt screw is smaller than the width of the external thread of the bolt.
Because the ring 2 is made of nylon plastics, after the ring is squeezed and pressed by a screw of a bolt, the friction force is increased, and the anti-loosening effect can be generated. Now, the glue 3 is used for gluing between the bolt and the bolt, so that larger adhesive force is realized, and the anti-loosening effect of the bolt fastener is further enhanced.
The annular grooves 21 distributed in the ring 2 are divided into an integral annular groove 21 and a partial annular groove 21: when the annular groove 21 is an integral annular groove 21, the two annular rings 2 with different sizes are sleeved and connected with each other in a plan view, the annular ring 2 is arranged outside, the annular groove 21 is arranged inside, and the heights of the two annular grooves are the same. The inner diameter of the integrally distributed annular groove 21 is smaller than that of the annular ring 2, the inner wall of the annular groove 21 is relatively thin, the annular groove is broken through extrusion of the external threads of the bolt, the glue 3 in the annular groove 21 flows out, and the outer threads and the inner wall of the annular ring 2 are in adhesive connection, so that the purpose of permanent looseness prevention is achieved. The diameter of the ring 2 is smaller than that of the bolt, so that after the external thread on the screw penetrates through the inner wall of the annular groove 21, the inner wall of the ring 2 can be extruded to form an indentation or a groove, friction is increased, and looseness prevention is achieved; when the annular groove 21 is a partial annular groove 21, the annular groove 21 forms a sealed cavity at the bottom of the ring 2. The cavity is located inside the ring 2, the glue 3 is filled in the cavity, and the inner wall of the cavity is relatively thin and is broken through extrusion of external threads. The inner diameter of the annular groove 21 is consistent with the inner diameter of the ring 2 and is connected up and down, and the ring 2 and the annular groove 21 are integrally of a hollow tube structure. The inner diameter of the annular groove 21 is smaller than that of the ring 2, and the annular groove 21 protrudes inwards for a circle on the inner wall surface of the ring 2 to form a larger sealed cavity to contain more glue 3. Wherein a protruding ring is connected with the surface of the nut 1. At this time, when the external thread of the bolt is connected to the nut 1, the external thread needs to pass through the annular groove 21 and then be connected to the inner wall of the ring 2. It is also possible to connect the inner wall of the ring 2 while contacting the annular groove 21.
The plastic film 4 is made of a material with poor tensile strength, and the surface of the plastic film 4 is broken through extrusion and stretching of the external threads on the screw rod, so that the glue 3 flows out. At the same time, the plastic film 4 also needs to have good air tightness so that the glue 3 in the annular groove 21 does not deteriorate or dry. The plastic film 4 comprises the following materials: plastic materials such as Polyethylene (PE), polyvinyl chloride (PVC), Polystyrene (PS), polyester, polyurethane, and the like. And a composite film containing an aluminum foil, or a composite film made by compounding a plurality of plastics. The plastic film 4 further comprises: a plastic panel. The plastic panel is connected with the opening side of the annular groove 21 in the ring 2 through adhesive bonding or hot melt fusion.
The ring 2 can be formed by mutually sleeving two hollow pipes with different sizes, a certain distance is reserved between the two sleeved hollow pipes, the upper surface and the lower surface of the two hollow pipes are connected in a sealing mode through the plastic film 4, and the glue 3 is filled in the interval part between the two hollow pipes. Or one surface of the hollow pipe is bonded or fused by plastic plate glue, and the other surface of the hollow pipe is bonded or fused by the plastic film 4 glue.
When the glue 3 is anaerobic glue, only a part of the glue is filled in the annular groove 21, so that the drying condition is prevented. When the glue 3 is strong adhesive of other types, the glue 3 stored in the groove is stable in performance and durable and effective due to the sealing structure formed by the annular groove 21 and the plastic film 4.
