Description

Technical Field

[0001] This utility model belongs to the field of bolt anti-collision technology, specifically a bolt anti-collision connecting sleeve structure. Background Technology

[0002] Bolts are widely used as critical connecting components in many fields such as mechanical assembly, construction, and equipment manufacturing. To prevent bolts from being corroded by the external environment and to avoid damage from accidental collisions, bolt protectors have become commonly used protective accessories. However, bolt protectors commonly available on the market, especially banana-shaped protectors, have revealed many defects in actual use.

[0003] In terms of protective performance, banana-shaped protective covers are mostly made of soft rubber or plastic. While these materials possess a certain degree of flexibility, their strength is limited. In harsh outdoor environments, such as prolonged exposure to sun, rain, and wind erosion, the material is prone to aging and becoming brittle, potentially leading to cracks or perforations within a short period. This exposes the internal bolts, significantly reducing the protective effect. For example, using ordinary banana-shaped protective covers on construction sites, after a quarter of exposure to wind and sun, approximately 30% of the covers show significant damage and can no longer protect the bolts.

[0004] In terms of connection stability, banana-shaped protective sleeves primarily achieve installation through an interference fit between the sleeve and the bolt. However, due to their simple structural design, when subjected to external forces such as equipment vibration and mechanical impact, the friction between the protective sleeve and the bolt is insufficient to maintain a tight fit, making them prone to displacement or even detachment. In some operating mechanical equipment, where internal bolts are frequently subjected to vibration, 15%-20% of banana-shaped protective sleeves show loosening or falling off within a week. This not only leaves the bolts unprotected but may also cause more serious malfunctions if the protective sleeve falls into the equipment. Faced with complex operating conditions, existing banana-shaped protective sleeves are insufficient to meet the requirements for stable bolt protection, necessitating innovative designs to improve their protective performance and connection stability.

[0029] See attached document Figure 1-3 This embodiment of a bolt anti-collision connecting sleeve structure includes a mounting base and a protective sleeve. The mounting base includes a ring washer and a boss. The mounting base has a clearance hole for the bolt to pass through. The boss has a groove, and a spring washer for the bolt is installed in the groove. The protective sleeve is fitted onto the boss and covers the bolt. The protective sleeve includes a cylindrical part and a ball head. The cylindrical part and the ball head are connected and integrally formed. The cylindrical part is mounted on the boss. The outer wall of the boss has a connecting structure that mates with the protective cap. The connecting structure can be any one of the following structures:

[0030] (1) The connection structure is an external thread structure, and the protective sleeve is provided with an internal thread for connection;

[0031] (2) The connection structure is a slanted snap-fit ​​structure, and the protective sleeve is directly fitted onto the boss for connection.

[0032] In this embodiment, when the connection structure is an external thread structure, the protective sleeve is made of a rigid material, the cylindrical part of the protective sleeve is provided with an internal thread, the protective sleeve has a threaded connection boss, and the cylindrical structure of the protective sleeve is provided with a hexagonal structure.

[0033] In this embodiment, the bottom edge of the boss is provided with a ring groove, and a rubber ring is provided inside the ring groove.

[0034] In this embodiment, when the connecting structure is a slanted snap-fit ​​structure, the protective sleeve is made of rubber, the middle of the connecting structure is provided with a ring groove, and the protective sleeve is provided with a ring structure, which is snap-fitted into the ring groove.

[0035] In this embodiment, when the bolt needs to be installed with a nut, the protective sleeve is used in pairs. The nut presses against the bolt, and the protective sleeve is placed on the tail of the bolt and covers the nut.

[0036] In this embodiment, the mounting base is made of metal, and the height of the boss is less than the thickness of the bolt head.

[0037] Working principle: This design is suitable for larger bolts. Small bolts do not require anti-collision protection. When the bolt is large, the bolt head protrudes significantly, making it easy to collide with people. Since the bolt is made of metal, the impact can easily cause injury. The protective sleeve protects the bolt body and also prevents impact. It should be noted that when the protective sleeve is made of a hard material, it should be made of a relatively soft material such as hard plastic. Overall, it is highly practical and provides high protection.
