Description
Technical Field
[0001] The present invention belongs to the technical field of machinery and relates to a figure-eight structure bolt Background Art
[0002] Pin connection is a commonly used engineering structure connection method. Generally, a hole needs to be drilled in the head of the main pin before inserting the locking rod. In order to prevent the locking rod from falling off during use, the locking rod also needs to be bent or fixed in other ways, resulting in very complex installation and disassembly. Therefore, in order to facilitate the installation and disassembly of engineering structures, a new type of figure-eight structure bolt needs to be developed Summary of the Invention
[0003] The purpose of the present invention is to overcome the above deficiencies existing in the prior art and provide a locking pin for engineering structures that is convenient for installation and disassembly
[0004] According to the technical solution provided by the present invention: the figure-eight structure bolt includes a bolt body and a locking rod; the bolt body includes a fixed end, a pin shaft, a pin head, and a locking hole. The pin shaft is the main body of the bolt body. The fixed end is arranged at the lower end of the pin shaft, the pin head is arranged at the upper end of the pin shaft, and the locking hole is arranged on the pin head; the locking rod includes a locking rod handle, a locking rod ring, and a locking rod pin. The locking rod handle is an open ring, the locking rod ring is a semi-ring, and the locking rod pin is a straight rod. The locking rod handle, the locking rod ring, and the locking rod pin are an integral rod
[0005] The advantages of the present invention are: compared with conventional pins, there is no need to fix the bolt during installation and disassembly. The installation can be directly completed by pushing the locking rod handle, and the bolt can be directly removed by rotating the locking rod handle, greatly simplifying the installation and disassembly operation procedures. The present invention is convenient for installation and disassembly, improving the work efficiency and safety performance of structure installation Brief Description of the Drawings

[0011] Description of the reference numerals in the drawings: bolt body 10, fixed end 11, pin shaft 12, pin head 13, locking hole 14, locking rod 20, locking rod handle 21, locking rod ring 22, locking rod pin 23 Embodiment
[0012] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0013] As Figure 1 shown: The present invention mainly consists of a pin body 10 and a locking rod 20; the pin body 10 includes a fixed end 11, a pin shaft 12, a pin head 13, and a locking hole 14 (see Figure 1 ), the pin shaft 12 is the main body of the pin body 10, the fixed end 11 is provided at the lower end of the pin shaft 12, the pin head 13 is provided at the upper end of the pin shaft 12, and the locking hole 14 is provided on the pin head 13; the locking rod 20 includes a locking rod handle 21, a locking rod ring 22, and a locking rod pin 23 (see Figure 2 ), the locking rod handle 21 is an open ring, the locking rod ring 22 is a semi-circular ring, the locking rod pin 23 is a straight rod, and the locking rod handle 21, the locking rod ring 22, and the locking rod pin 23 are an integral rod.
[0014] In specific applications, as Figure 3 , Figure 4 , Figure 5 shown. During installation, first insert the pin head 13 into the connection hole of the component to be locked until the locking hole 14 completely passes through the locking component, and then insert the locking rod pin 23 into the locking hole 14 (see Figure 3 ). Push the locking rod handle 21 forcefully. When the locking rod pin 23 completely enters the interior of the locking hole 14, the semi-circular ring of the locking rod ring 22 completely enters the outer surface on the right side of the pin shaft 12. At this time, under the action of its own elastic force, the locking rod ring 22 rotates 90 degrees clockwise, making the present invention in a locked state (see Figure 4 ), so as to achieve the purpose of locking the connecting component. During disassembly, rotate the locking rod handle 21 counterclockwise by 90 degrees. Due to the action of its own elastic force, the locking rod pin 23 exits from the locking hole 14, and the pin head 13 can then exit from the connection hole of the component to be locked (see Figure 5 ), so as to achieve the purpose of separating the locked connecting component.
[0015] When installing and disassembling the present invention, no fixed pin is required. The installation is directly completed by pushing the locking rod handle, and the pin can be directly removed by rotating the locking rod handle. It is not easy to fall off, the locking is safer, and the installation and disassembly operation procedures are greatly simplified. The present invention is convenient for installation and disassembly, improving the work efficiency and safety performance of the structure installation.
