Description

Technical Field

[0001] The utility model belongs to the field of fastening pins, and particularly relates to a fastening pin convenient for disassembly and a unilateral limiting mechanism. Background Art

[0002] A pin is a type of standardized fastener that can be used for static fixed connection or relative movement with the connected parts. It is mainly used at the hinge joint of two parts to form a hinge connection. The pin is usually locked with an opening pin, which is reliable in work and convenient for disassembly.

[0003] When using pins in large parts, if the pins rotate frequently, it is easy to cause loose fixation and falling off. Therefore, the pins need to be relatively fixed to ensure the stability of the installation position. In the working conditions where the pins need to be frequently disassembled and assembled, it is difficult to disassemble the fixedly installed pins, which affects the work efficiency.

[0004] In the prior art, in the tooling fixtures of agricultural machines, engineering machines and automobiles, there are a large number of frame structure main frames. When manufacturing and processing the main frame, riveting or welding is required for the connection positions of the main frame. After the connection is completed, the whole main frame needs to be subjected to anti-corrosion spraying. When maintaining and repairing the main frame, it is necessary to find and maintain the repair points of the main frame. During the operation process, it is necessary to limit and fix the main frame to avoid production accidents. Summary of the Invention

[0034] As Figure 1 shown, a detachable fastening pin shaft includes a pin shaft main body 1. A fastening portion 4 is arranged on the periphery of the pin shaft main body 1, and the pin shaft main body 1 is fixedly sleeved on the first implemented part through the fastening portion 4; and the periphery of the fastening portion 4 is in interference fit with the insertion hole of the first implemented part.

[0035] One end of the pin shaft body 1 is provided with a baffle 2, and a fixing component 3 is provided at the other end of the pin shaft body 1.

The relative position of the pin shaft body 1 and the first implemented part is defined by the baffle 2 and the fixing component 3, and the relative rotation of the second implemented part and the pin shaft body 1 is realized through the shaft sleeve 5, so as to prevent the pin shaft body 1 from rotating when the second implemented part rotates, and ensure the relative rotation of the second implemented part and the first implemented part.

[0036] During implementation, there are various implementation manners for the fastening part 4. In order to reduce the contact surface of the fastening part 4 with the first implemented part, as Figure 1 shown, the fastening part 4 includes a plurality of bosses, and the plurality of bosses are arranged circumferentially along the periphery of the pin shaft body 1, and each boss is close to one end of the pin shaft body 1.

[0037] There are various implementation manners for the fixing component 3 during implementation. As Figure 1 shown, the first embodiment of the fixing component 3 is a split pin.

[0038] As Figure 2 and Figure 3 shown, a unilateral limiting mechanism includes a linear driving component 6. The execution end of the linear driving component 6 is hinged to a limiting plate 8. A supporting plate 9 is fixedly arranged on the periphery of the linear driving component 6. A connecting component 7 is arranged between the limiting plate 8 and the supporting plate 9, and both ends of the connecting component 7 are respectively connected to one end of the limiting plate 8 and one end of the supporting plate 9 through one of the above-mentioned detachable fastening pins.
