[0026] This specific embodiment is a pin-type device.

[0027] The aforementioned utility model allows for the selection of bushings and pressure plates of different sizes according to the different sizes of the pins, eliminating the need to replace the entire connecting device and improving work efficiency. This utility model is a pin-type device applied in the field of logistics transportation technology. Long logistics conveyor lines consist of multiple sets of conveyors connected together, divided into fixed equipment and movable equipment. In cases of emergency position adjustments, the connecting installation structure must be disassembled before the movable equipment can be moved. Furthermore, for conveyor equipment located at fire doors, the disassembly time is too long when the fire doors need to be closed in an emergency, affecting the efficiency of conveyor disassembly.

[0028] Its structural diagram is as follows Figures 1-5 As shown. A pin-type device includes a frame 1. Multiple sets of mounting holes are provided on both sides of the top and side walls of the frame 1. Multiple sets of positioning bearing seats 11 are fixedly installed on the inner walls of both sides of the frame 1, and conveying rollers 12 are rotatably mounted between the positioning bearing seats 11. A pulley body 13 is fixedly installed at one end of each conveying roller 12, and the conveying rollers 12 are connected to the pulley bodies 13 via a transmission belt 14 to drive the conveying rollers 12. A drive device connected to the frame 1 drives the conveying rollers 12, connecting them via the transmission belt 14. This ensures the efficient material transport of the device. A snap-fit ​​opening 15 is provided on the side wall of the frame 1, and the positioning bearing seats 11 are fixedly installed to the side wall of the frame 1 by mounting bolts 16. Multiple sets of insert-type snap-fits 17 and multiple sets of limit-type snap-fits 18 are respectively snapped into one side of the positioning bearing seat 11 through the snap-fit ​​opening 15, and the bottom of the limit-type snap-fits 18 is snapped and fixed to the mounting bolts 16. The internal structure of the equipment frame 1 is secured by insert-type buckles 17 and limit-type buckles 18 and buckle openings 15 on the side wall of the equipment frame 1, thereby increasing the tightness of the installation.

[0029] The equipment frame 1 is connected and locked together by a pin plate 2 and a locking mechanism 3. The pin plate 2 has three sets of through holes, and the locking mechanism 3 passes through one set of through holes on the pin plate 2 and one set of mounting holes on the equipment frame 1. The locking mechanism 3 includes a positioning rod 34 passing through the pin plate 2, a welding block 31 fixedly installed at the bottom of the positioning rod 34, a welding connecting rod 32 welded to the bottom of the welding block 31, and a locking ring 33 fixedly installed at the bottom of the welding connecting rod 32. The positioning rod 34 has an insertion hole 341. The pin plate 2 is fixedly secured with a pin 35 passing through the positioning rod 34. The pin 35 passes through the positioning rod 34 to position the locking mechanism 3, ensuring the stability of the locking mechanism 3 during use. An auxiliary frame 4 is fixedly installed at the bottom of the locking mechanism 3 to the side wall of the equipment frame 1.

[0030] The auxiliary frame 4 is fixedly installed to the outer wall of the equipment frame 1 by fixing bolts 41. A limiting protrusion 42 is integrally installed on the top of the auxiliary frame 4. The locking ring 33 is engaged with the limiting protrusion 42 for positioning. The engagement between the locking ring 33 and the limiting protrusion 42 increases the stability of the two sets of equipment frames 1 during use. A frustum buckle 21 is installed through the through hole at the other end of the pin plate 2, penetrating the pin plate 2 and the equipment frame 1. The top of the frustum buckle 21 is limited by a positioning piece 22, and the positioning piece 22 has a positioning groove 23. Positioning ends 351 are fixedly installed on both sides of the pin rod 35, and the positioning groove 23 is engaged with a set of positioning ends 351 for fixation. The positioning end 351 at one end of the pin rod 35 limits and fixes the frustum buckle 21, while the other end is supported and positioned by a positioning rod 34. The pin rod 35 is supported by the pin plate 2. During the assembly and use of the equipment frame 1, the locking ring 33 and the limiting protrusion 42 lock together, ensuring the stability of the equipment frame 1 during transportation when the two sets of equipment frame 1 are not installed together with bolts. In case of emergency, if one set of equipment frame 1 needs to be disassembled, simply pull the pin rod 35 out of the insertion hole 341, and push it out from the bottom of the frustum buckle 21 so that it can be removed from the top of the positioning piece 22. This achieves the disassembly of both sets of equipment frame 1, improving the disassembly speed. It ensures the fixation of the movable equipment and allows the equipment to be disassembled and moved at any time, saving operation time.

[0031] First, during installation, place the two sets of equipment frames 1 in their designated positions. Place the pin plate 2 on top of one set of equipment frames 1, and install the frustum buckle 21 through the through hole at the top of the pin plate 2 and the mounting hole at the top of the equipment frame 1, so that the positioning piece 22 limits the position of the frustum buckle 21. After assembling the locking ring 33 at the bottom of the limiting protrusion 42, install the auxiliary frame 4 on the outer wall of the equipment frame 1, and push the locking ring 33 upward to make the positioning rod 34 pass through the equipment frame 1 and the pin plate 2. Finally, use the pin rod 35 to pass through the insertion hole 341 and pull the positioning rod 34 so that the positioning end 351 at the other end of the pin rod 35 engages with the positioning groove 23 at the top of the positioning piece 22, thus completing the installation. During disassembly, simply pull up the pin 35, remove the pin 35 from the insertion hole 341, and push it from the bottom of the frustum buckle 21 so that it can be removed from the top of the positioning piece 22, thus achieving the disassembly of the two sets of equipment frames 1.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
