Therefore, the above terms should not be understood as limiting the present application.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] refer to Figures 1 to 8 According to a preferred embodiment of the present application, a three-dimensional drag chain will be described in detail below. The three-dimensional drag chain includes a mounting frame 10, and the mounting frame 10 includes at least one mounting body 11. Each mounting body 11 includes at least two body parts 111. At least two body parts 111 are detachably connected to form a whole, and at least two body parts 111 are connected to form a receiving space 1101. The receiving space 1101 is used to receive cables and pipes. In this way, the detachable design of the body part 111 increases the convenience of cable and pipe installation.

[0030] The mounting frame 10 further includes at least one dust removal member 12, the dust removal member 12 having a dust removal cavity 1201, the mounting body 11 being connected to the peripheral side of at least one dust removal member 12, and the accommodating space 1101 of each mounting body 11 being communicated with the dust removal cavity 1201 of at least one dust removal member 12. The mounting body 11 and the dust removal member 12 are both capable of flexible deformation, and the hardness of the dust removal member 12 is higher than that of the mounting body 11, so that the deformation speed of the dust removal member 12 is faster than that of the mounting body 11. When the mounting frame 10 is bent to increase the gap at the connection between two adjacent body parts 111, the gas in the dust removal cavity 1201 is squeezed and partially introduced into the accommodating space 1101 to drive the gas flow in the accommodating space 1101, and at least part of the dust in the accommodating space 1101 is driven and discharged from the gap at the connection between two adjacent body parts 111 along with the gas, so as to achieve dust removal.

[0031] It is worth mentioning that in the process of the installation skeleton 10 restoring and the gap at the connection between the two adjacent main body parts 111 gradually decreasing, the external dust-entrained gas is attracted and flows into the accommodating space 1101 through the gap at the connection between the two adjacent main body parts 111 and at least partially flows into the dust removal chamber 1201, so as to reduce the dust in the accommodating space 1101.

[0032] In this way, when the mounting frame 10 is bent, the dust in the accommodating space 1101 is brought out by the gas flow caused by the bending and squeezing of the internal gas by the dust removal piece 12, so as to automatically remove dust from the accommodating space 1101, thereby effectively preventing the accommodating space 1101 from being occupied by too much dust and reducing the movable space of the cables and pipes therein, thereby preventing the cables and pipes from being rubbed and scratched.

The card block can undergo elastic deformation. The two main bodies 111 are assembled into one in a manner that each card block corresponds to and snaps into the corresponding bayonet.

The two blocking members 123 are respectively installed on the dust removal body 122 so that the two vents 12201 can be opened and closed. One of the vents 12201 is used to introduce gas into the dust removal cavity 1201. The dust in the dust removal cavity 1201 is driven by the gas and discharged from the other vent 12201, so as to remove the dust brought into the dust removal cavity 1201 when the mounting frame 10 is restored, so as to clean the dust removal cavity 1201 and facilitate subsequent dust removal.
