Technical Field
[0001] The invention relates to the field of pins, in particular to an assembled pin. Background Art
[0002] In the field of mechanical assembly, pins are a common connector and are widely used in the assembly and fixation of various equipment. Traditional pin designs often use a single fixing method, such as threaded connection or pin hole matching. Although these methods can meet basic requirements in terms of connection strength and stability, they are inconvenient during assembly and disassembly.
[0003] Specifically, when assembling a traditional pin, it is usually necessary to use tools to tighten or knock, which not only increases the complexity of assembly, but may also cause damage to the pin or connecting parts. When disassembling, special tools are also required, and the disassembly process is often cumbersome, time-consuming and labor-intensive. In addition, after long-term use, the traditional pin may fail due to wear or loosening of the connection parts, affecting the normal operation of the equipment.
[0004] Therefore, the market is in urgent need of a new type of assembled pin shaft, which can simplify the assembly and disassembly process, improve work efficiency, and reduce the risk of damage to the connecting parts while ensuring the connection strength and stability. Summary of the invention

[0027] See also Figure 1-Figure 9 The present invention provides a technical solution: an assembled pin shaft, including a pin shaft body 1, a through hole 2 is provided on the surface of the pin shaft body 1, a plug handle 17 is inserted inside the through hole 2, the through hole 2 is a square hole, the through hole 2 is centered at one end of the pin shaft body 1, the plug handle 17 is a square rod, the rod length of the plug handle 17 is equal to the depth of the through hole 2, a baffle 3 is fixed to one end of the plug handle 17, and an assembly groove 4 is provided at the other end of the pin shaft body 1, and the assembly groove 4 is an annular groove. A collar 5 is inserted into the interior of the groove 4, one end of the collar 5 is fixed on the surface of the baffle 3, the outer ring diameter of the collar 5 is equal to the rod diameter of the pin shaft body 1, the baffle 3 is a circular plate, the circular surface diameter of the baffle 3 is larger than the rod diameter of the pin shaft body 1, the inner ring surface of the collar 5 is provided with a card groove 6, the card groove 6 is an annular groove, a rubber ring 7 is sleeved and fixed on the surface of the assembly groove 4, the outer diameter of the rubber ring 7 is larger than the inner diameter of the collar 5, after the collar 5 is sleeved on the assembly groove 4, the rubber ring 7 is inserted into the card groove 6.
[0028] When in use, it is necessary to separate the handle 17 and the pin shaft body 1, and then after the pin shaft body 1 passes through the workpiece to be installed, push the handle 17 into the through hole 2. When the handle 17 is completely pushed into the through hole 2, the ring 5 is sleeved on the assembly groove 4. At this time, the rubber ring 7 is inserted into the card groove 6, which increases the friction between the assembly groove 4 and the ring 5, and prevents the assembly groove 4 from falling off when there is no external force, thereby realizing the pre-limitation of the handle 17 after being inserted into the through hole 2.
[0029] A reserved groove 8 is provided at one end of the pin shaft body 1 away from the baffle 3, and an insert block 11 is inserted on the surface of the reserved groove 8. One end of the insert block 11 is inserted on the surface of the plug handle 17 to limit the plug handle 17. Two reserved grooves 8 are provided, and the two reserved grooves 8 are symmetrically distributed about the through hole 2. A socket 9 is provided on the surface of the reserved groove 8, and the socket 9 connects the reserved groove 8 and the through hole 2. The insert block 11 penetrates the socket 9 and is inserted into the positioning port 10. The positioning port 10 is provided on the surface of the plug handle 17. The length of the insert block 11 is greater than the depth of the socket 9. One end of the insert block 11 extending into the positioning opening 10 is provided with an inclined surface 12, and the inclined surface 12 faces the blocking piece 3; a shift block 13 is fixed to the other end of the insert block 11, and the shift block 13 is slidably connected in the reserved groove 8, and a pick-out groove 16 is provided on the surface of the shift block 13; a rubber support block 14 is fixed to the surface of the shift block 13, and one end of the rubber support block 14 is fixed to the surface of the reserved groove 8. When the rubber support block 14 is in the initial state, the rubber support block 14 pushes the insert block 11 through the socket 9 and inserts it into the positioning opening 10, and a reserved hole 15 is provided on the surface of the rubber support block 14.
[0030] When the handle 17 is pushed into the through hole 2, one end of the handle 17 pushes the plug block 11 along the inclined surface 12. When the plug block 11 slides along the socket 9, the plug block 11 squeezes the rubber support block 14 through the shifting block 13 to produce elastic deformation. Until the handle 17 is fully inserted into the through hole 2, the plug block 11 and the positioning hole 10 are opposite. At this time, the rubber support block 14 rebounds and drives the plug block 11 to move back. One end of the plug block 11 is inserted into the positioning hole 10. That is, at this time, the handle 17 is firmly limited in the through hole 2, and the end plate body and the blocking piece 3 of the pin shaft body 1 are respectively distributed on both sides of the workpiece to prevent the pin shaft body 1 from falling off from the workpiece; when the pin shaft body 1 needs to be disassembled, two fingers are respectively picked in the two picking grooves 16, and the corresponding shifting block 13 is moved to squeeze the corresponding rubber support block 14 until the plug block 11 is pulled out from the corresponding positioning hole 10. At this time, after the blocking piece 3 is pulled out to pull the handle 17 out of the through hole 2, the pin shaft body 1 can be pulled out from the workpiece.
[0031] The usage process specifically includes: Assembly process: Separate the plug handle and the pin shaft body: In the initial state, the plug handle 17 and the pin shaft body 1 are separated. Install the pin shaft body: Pass the pin shaft body 1 through the workpiece to be installed. Push the plug handle: Push the plug handle 17 into the through hole 2 until it is fully inserted. During the pushing process of the plug handle 17, one end of the plug handle 17 pushes the plug block 11 along the inclined surface 12 of the plug block 11. The plug block 11 slides along the socket 9 and squeezes the rubber support block 14 through the shift block 13 to cause it to produce elastic deformation. Sleeve the ring and rubber ring: When the plug handle 17 is fully inserted into the through hole 2, the ring 5 is sleeved on the assembly groove 4. The rubber ring 7 is inserted into the card slot 6 to increase the friction between the assembly groove 4 and the ring 5 to achieve pre-limitation. Block limit: When the plug handle 17 is fully inserted into the through hole 2, the plug block 11 and the positioning port 10 are opposite. At this time, the rubber support block 14 rebounds, driving the insert block 11 to move back, and one end of the insert block 11 is inserted into the positioning hole 10. The insert handle 17 is firmly limited in the through hole 2, and the end plate body and the stopper 3 of the pin shaft body 1 are respectively distributed on both sides of the workpiece to prevent the pin shaft body 1 from falling off the workpiece.
[0032] Disassembly process: Move the shifting block: When the pin shaft body 1 needs to be disassembled, two fingers are respectively placed in the two picking grooves 16. Move the corresponding shifting block 13 and squeeze the corresponding rubber support block 14 until the insertion block 11 is pulled out of the corresponding positioning port 10. Pull out the insertion handle and the pin shaft body: Pull the blocking piece 3 and pull the insertion handle 17 out of the through hole 2. Pull out the pin shaft body 1 from the workpiece.
