[0002] Bolts are mechanical parts, cylindrical threaded fasteners that fit into nuts. These fasteners consist of a head and a shank (a cylindrical body with external threads). They are used with a nut to fasten two parts with through-holes. This type of connection is called a bolted connection.

[0003] The Chinese patent with the authorization publication number CN217976950U discloses a bolt, comprising a nut and a screw, wherein the lower end surface of the nut is provided with a coaxial screw. The screw (2) comprises a first round rod (21), a first truncated cone (22), a second round rod (23), an external thread (231), and a second truncated cone (24). The first round rod (21) is vertically arranged on the lower end surface of the nut (1), the lower end surface of the first round rod (21) is provided with a coaxial first truncated cone (22), the lower end surface of the first truncated cone (22) is provided with a coaxial second round rod (23), the outer side wall of the second round rod (23) is provided with an external thread (231), and the lower end surface of the second round rod (23) is provided with a coaxial second truncated cone (24). The utility model can make the threads of the threaded connection tightly matched and not easy to loosen, thereby making the bolt not easy to loosen and the bolt firmly installed.

[0004] Although the bolts mentioned above can make the threads of the threaded connection fit tightly and not easy to loosen, thereby making the bolts not easy to loosen and the bolts firmly installed, since the bolts are generally made of metal, they are prone to corrosion after being fixed for a long time and cannot be disassembled. For this reason, we propose a bolt that can be quickly disassembled. Summary of the Invention

[0008] A sealing cover is installed above the oil filling port, and a docking hole is provided on the outer side of the oil filling port.

[0009] Preferably, the engaging groove, the bolt head and the center point of the bolt shank are located on the same vertical line, and the threaded portion is fixedly connected to the bolt shank.

[0010] Preferably, the oil filling port forms a communication structure between the fluid channel and the dispersion channel, and the dispersion channels are evenly distributed.

[0011] Preferably, the sealing cover is engaged with the oil filling port through the docking hole, and an elastic structure is formed between the sealing cover and the oil filling port.

[0012] Preferably, the sealing cover is further provided with:

[0013] The limiting slide is installed on both sides above the sealing cover. One end outside the limiting slide is connected to a telescopic block, and the outer side of the telescopic block is connected to a telescopic spring.

[0014] Preferably, the limiting slides are symmetrically distributed about the vertical center line of the sealing cover, and the limiting slides form an elastic structure through the telescopic block and the telescopic spring.

[0015] Compared with the prior art, the present invention provides a quickly detachable bolt, which has the following beneficial effects:

[0016] The utility model can inject lubricating oil into the fluid channel through the oil filling port, and the lubricating oil can flow to the outer wall of the bolt rod through various dispersed channels, thereby lubricating the connection and loosening the corroded part, avoiding the problem that the bolt is generally made of metal and is prone to corrosion after being fixed and installed for a long time, resulting in the situation that it cannot be disassembled.
