Description

Technical Field

[0001] This utility model relates to the field of bolt connection assembly technology, and in particular to a bolt connection assembly that is easy to disassemble. Background Technology

[0002] Bolted connections are a common type of mechanical connection. By passing bolts through holes in the connectors and tightening them with nuts and washers, sufficient pressure is generated to ensure a secure connection. The main advantage of bolted connections is their detachability; the connectors can be removed by unscrewing the nuts and bolts, making them suitable for structures that require disassembly, repair, adjustment, or reassembly.

[0003] When using easily disassembled bolted connections, a nut, washer, and bolt are typically used together to complete the connection. The nut is fixed to the bolt by rotation, creating a tight connection between the bolt and the connector, ensuring the stability of the connection. The washer plays several important roles: it effectively alleviates heat and wear generated by friction between the bolt and the connector, and it evenly distributes the pressure applied to the connector, preventing localized damage caused by pressure concentration. However, traditional bolt and washer fixing methods usually rely on threads or simple snap-fit ​​structures. While these methods can achieve an effective connection in the short term, they pose certain risks under long-term use or in high-vibration environments. Threads are prone to wear during repeated tightening and loosening, and snap-fit ​​structures are prone to loosening under vibration or external forces, causing the connection between the bolt and the connector to become loose. Therefore, with increased use or in frequently vibrating working environments, the connection structure may gradually fail, creating safety hazards. Utility Model Content

The soft pad 203 is movably connected to the outer surface of the bolt body 1.

[0034] In this embodiment, after the washer 101 is fixed to the bolt body 1, the operator can put the second nut 204 on the outer surface of the bolt body 1 and rotate the second nut 204 to push the soft pad 203 to move. After the soft pad 203 moves to the appropriate position, it will fit against the other side of the connector to connect the bolt body 1 to the connector. Then, the first nut 2 is picked up and put on the right outer surface of the bolt body 1. The first nut 2 is rotated to move to the left side of the outer surface of the bolt body 1. At the same time, the first nut 2 drives the sleeve... The sleeve 201 moves synchronously. When the sleeve 201 moves to the appropriate position, it will drive the thread 202 on the sleeve 201 to be embedded in the thread groove 107 on the washer 101. Then, through the sleeve 201, the first nut 2 can be fixed with the washer 101 and the bolt body 1. Through the structure of the sleeve 201 and the thread 202, the first nut 2 can be fixed with the washer 101 and the bolt body 1 through the sleeve 201, forming an integral connection structure, which significantly improves the stability of the overall structure and further improves the strength of the entire connection structure.

[0035] Working principle: In use, the operator first inserts the bolt body 1 into the connector and pulls the pin 102 outward, allowing it to slide outward inside the washer 101. Simultaneously, the pin 102 pulls the return spring 103 to extend. Then, the washer 101 is fitted onto the outer surface of the bolt body 1, and pushed, allowing it to slide on the outer surface of the bolt body 1. After sliding to a suitable position, the operator releases the pin 102, causing the return spring 103 to return to its original position. Simultaneously, the return spring 103 pulls the pin 102 inward, allowing the two pins 102 to engage. The pin 101 is inserted into the groove 106, and the connecting post 104 is simultaneously inserted into the groove 105 to fix the washer 101 to the bolt body 1. The bolt body 1 is then pushed so that the washer 101 can fit against the outer surface of the connector. Through the structure of the washer 101 and the pin 102, the washer 101 can be quickly fixed to the bolt body 1, simplifying the installation and disassembly process and improving efficiency. At the same time, the washer 101 is fixedly connected to the bolt body 1 through the pin 102, which can ensure that the washer 101 is firmly fixed to the bolt body 1, avoiding the loosening problem caused by long-term use or vibration in traditional bolt connections. In use, after the washer 101 is fixed to the bolt body 1, the operator can put the second nut 204 on the outer surface of the bolt body 1 and rotate the second nut 204 to move the soft pad 203. After the soft pad 203 moves to the appropriate position, it will fit against the other side of the connector to connect the bolt body 1 to the connector. Then, the first nut 2 is picked up and put on the right outer surface of the bolt body 1. The first nut 2 is rotated to move to the left side of the outer surface of the bolt body 1.
