The thru axle can be used to quickly disassemble and assemble the wheel, which is convenient for subsequent vehicle maintenance. The bicycle's quick-release thru axle is mainly used to quickly combine and disassemble the wheel and the frame (or the fork on the frame).

[0003] A bicycle hidden tube axle with Chinese patent number CN220220270U includes an axle body and a fastener, wherein the upper end of the axle body is fixedly connected to the fastener; further comprising: a positioning member fixedly installed on the inner side of the fastener; and a storage hole opened in the middle position of the fastener. The bicycle hidden tube axle can adjust the handle telescopically, thereby facilitating the hidden storage of the handle, effectively preventing the handle from being caught by foreign objects during riding.

[0004] Since the barrel-axle structure cross bar needs to be disassembled multiple times inside and outside the bicycle wheel, and there is a blockage between the barrel-axle structure cross bar and the installation base surface, when lubricating oil is needed for auxiliary installation, since the barrel-axle structure cross bar is not provided with a lubricating oil channel, the auxiliary installation process is relatively inconvenient and it is not easy to ensure the smooth installation of the barrel-axle structure cross bar.

[0005] To this end, a barrel shaft structure provided with a lubricating oil passage is proposed. Utility Model Content

[0006] In view of this, the utility model provides a barrel shaft structure provided with a lubricating oil passage to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0008] Further preferably, strip sliders are symmetrically fixedly connected to the left and right sides of one end of the sealing plug ring close to the oil storage cavity, and the corresponding strip grooves are slidably connected to the strip sliders.

[0009] Further preferably, an outer end of the oil storage cavity is fixedly connected with an oil-coated flexible cloth ring, and the oil-coated flexible cloth ring cooperates with the lubricating oil liquid.

[0010] Further preferably, a front connecting piece is installed at the front end of the cylindrical shaft structure cross bar, and a rear connecting piece is installed at the rear end of the cylindrical shaft structure cross bar.

[0011] Further preferably, a rotation hole is provided at the rear end of the rear connecting member, and an extension handle is fixedly connected to the right end of the rear connecting member.

[0012] Further preferably, a lower inclined groove is provided at the lower end of the extended handle, and an arrow indicator mark is fixedly connected to the front end of the extended handle.

[0013] Further preferably, the cross bar of the barrel shaft structure passes through the inside and outside of the bicycle wheel, and the lubricating oil extends out of the outside of the oil storage cavity through the oil outlet hole.

[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. This solution utilizes a barrel shaft structure cross bar installed inside and outside the bicycle wheel for connection and easy disassembly. An oil storage cavity is arranged outside the structure cross bar. The oil storage cavity can be filled with lubricating oil for use at any time. When auxiliary lubrication is required, the oil storage cavity can be slid from the outside of the sealing plug ring to expose the oil outlet hole. When the barrel shaft structure cross bar passes through the inside and outside of the bicycle wheel, the lubricating oil can smoothly overflow to the installation base surface for auxiliary lubrication.

[0016] 2. At the same time as applying the lubricating oil, a flexible cloth ring for oiling can be added outside the oil storage cavity. The flexible cloth ring for oiling can assist in applying the lubricating oil to the installation base surface, making the lubricating oil application operation more uniform and comprehensive, which is beneficial to ensuring the auxiliary lubrication efficiency of the lubricating oil. At the same time, after the lubricating oil is applied, the sealing plug ring can be pushed back to the outside of the oil storage cavity for reset, so that the rubber plug is engaged in the oil storage cavity, and the remaining lubricating oil is sealed, which is convenient for next use and not easy to cause waste.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5 As shown, an embodiment of the utility model provides a cylindrical shaft structure with a lubricating oil channel, including a cylindrical shaft structure cross bar 1, an outer end of the cylindrical shaft structure cross bar 1 is provided with an oil storage cavity 7, the outer end of the oil storage cavity 7 is slidably connected with a sealing plug ring 9, the outer end of the oil storage cavity 7 is provided with a plurality of oil outlet holes 11, and the sealing plug ring 9 is fixedly connected with a plurality of rubber plugs 12 at one end close to the oil storage cavity 7, the plurality of rubber plugs 12 are mutually engaged with the oil outlet holes 11, the inner end of the oil storage cavity 7 is filled with a plurality of lubricating oil liquids 10, and strip grooves 13 are symmetrically provided at the left and right ends of the oil storage cavity 7.

[0029] A strip slider 14 is symmetrically fixedly connected to the left and right sides of one end of the oil storage cavity 7 through a sealing plug ring 9, and the corresponding strip groove 13 is slidingly connected to the strip slider 14. An oil-coated flexible cloth ring 8 is fixedly connected to the outer end of the oil storage cavity 7, and the oil-coated flexible cloth ring 8 cooperates with the lubricating oil liquid 10. A front connecting piece 2 is installed at the front end of the cylindrical shaft structure cross bar 1, and a rear connecting piece 5 is installed at the rear end of the cylindrical shaft structure cross bar 1.

[0030] Example 2

[0031] In one embodiment, a rotation hole 6 is formed at the rear end of the rear connecting member 5 , an extension handle 3 is fixedly connected to the right end of the rear connecting member 5 , and a lower inclined groove 4 is formed at the lower end of the extension handle 3 .

[0032] An arrow indicator 15 is fixedly connected to the front end of the extended handle 3 , the cylindrical shaft structure cross bar 1 passes through the inside and outside of the bicycle wheel, and the lubricating oil 10 extends out of the outside of the oil storage cavity 7 through the oil outlet hole 11 .

[0033] When the utility model is working: this scheme utilizes the installation of the barrel shaft structure cross bar 1 inside and outside the bicycle wheel for connection and easy disassembly. Since the barrel shaft structure cross bar 1 needs to be disassembled multiple times inside and outside the bicycle wheel, and there is a blockage between the barrel shaft structure cross bar 1 and the installation base surface, when lubricating oil is needed for auxiliary installation, the oil storage cavity 7 can be slid from the outside of the sealing plug ring 9 to expose the oil outlet hole 11.
