Description

Anti-collision connecting sleeve structure for bolt Technical Field The utility model belongs to the technical field of bolt anti-collision, and particularly relates to a bolt anti-collision connecting sleeve structure. Background Bolts are widely used as key connectors in many fields such as mechanical assembly, construction, equipment manufacturing, etc. In order to prevent the bolts from being corroded by the external environment and avoid accidental collision damage, the bolt protection sleeve is a common protection accessory. However, the bolt protection sleeves currently in common use in the market, particularly banana type protection sleeves, expose a number of drawbacks in practical use. From the aspect of protective performance, the banana protective sleeve is made of soft rubber or plastic materials. Such materials have limited strength, although they have some flexibility. Under outdoor severe environment, if the outdoor severe environment is subjected to sun and rain and wind and sand erosion for a long time, the materials are easy to age and become brittle, and the conditions of cracking, perforation and the like can possibly occur in a short time, so that the internal bolts are directly exposed, and the protection effect is greatly reduced. Taking the bolt on the construction site as an example, a common banana protective sleeve is used, and about 30% of the protective sleeve is obviously damaged after being blown and sunned in a quarter, so that the bolt cannot be continuously protected. In connection stability, the banana protective sleeve is installed mainly through interference fit of the sleeve body and the bolt. However, due to the simple structural design, when external forces such as equipment vibration and mechanical impact are applied, the friction force between the protective sleeve and the bolt is insufficient to maintain close fit, and displacement and even falling are very easy to occur. Like some mechanical equipment in operation, its inside bolt frequently bears the vibration, adopts banana protective sheath, has 15% -20% to appear becoming flexible in a week, and this not only makes the bolt lose the protection, and perhaps gets into inside the equipment because of the protective sheath drops, causes more serious trouble. In the face of complex working conditions, the requirement of stable protection of bolts is difficult to meet by the existing banana protective sleeve, and innovative design is needed urgently, so that the protection performance and connection stability of the banana protective sleeve are improved. Disclosure of utility model The present utility model aims to solve the problems set forth in the background above. In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: The utility model relates to a bolt anti-collision connecting sleeve structure, which comprises a mounting seat and a protective sleeve, wherein the mounting seat comprises a ring pad and a boss, a clearance hole for a bolt to pass through is formed in the mounting seat, a notch is formed in the boss, a spring pad for the bolt is arranged in the notch, the protective sleeve is sleeved on the boss, the protective sleeve coats the bolt, the protective sleeve comprises a cylindrical part and a ball head part, the cylindrical part is connected with the ball head part and is integrally formed, the cylindrical part is arranged on the boss, a connecting structure matched with a protective cap is arranged on the outer wall of the boss, and the connecting structure is any one of the following structures: (1) The connecting structure is an external thread structure, and the protective sleeve is correspondingly provided with an internal thread for connection; (2) The connecting structure is an inclined clamping structure, and the protective sleeve is directly sleeved on the boss for connection. Preferably, when connection structure is external screw thread structure, the protective sheath is the stereoplasm material, and the cylinder portion of protective sheath is equipped with the internal thread, protective sheath threaded connection boss, be equipped with hexagonal structure on the cylinder structure of protective sheath.
