[0025] Reference Figures 1 to 5 , the flexible dustless tow chain of a preferred embodiment of the utility model will be described in detail below. The flexible dustless tow chain comprises a supporting mechanism 10, a cable layer 20 and two assembly mechanisms 30, the cable layer 20 and the supporting mechanism 10 are distributed up and down, and the supporting mechanism 10 provides support for the cable layer 20.

[0026] The supporting mechanism 10 comprises a plurality of spaced keel chains 11. Each keel chain 11 comprises a plurality of keel sections 111 and two joints 112. A plurality of keel sections 111 are hingedly connected at the head and tail, and two joints 112 are respectively hingedly connected to the keel sections 111 at the head and tail.

[0027] The cable layer 20 comprises a plurality of cables 21 distributed at intervals. Each set of the assembling mechanism 30 comprises an assembling component 31. Each assembling component 31 forms a first mounting space 3101 and a second mounting space 3102. The end of the keel chain 11 is inserted into the first mounting space 3101 formed by the assembling component 31, and the end of the cable 21 is inserted into the second mounting space 3102 formed by the assembling component 31, that is, two assembling mechanisms 30 are respectively mounted at the two ends of the support mechanism 10 and the cable layer 20.

[0028] Preferably, the joint 112 forms a connecting structure 1121. The inner wall of the first mounting space 3101 forms a mounting structure 3103 matched with the connecting structure 1121. The joint 112 is assembled with the assembling component 31 in a manner that the connecting structure 1121 is assembled with the mounting structure 3103.

[0029] In an embodiment, the mounting structure 3103 is implemented as a groove, and the connecting structure 1121 is implemented as a protrusion.

[0030] Preferably, the joint 112 forms an adjusting groove 112101 on the connecting structure 1121, and the extending direction of the mounting structure 3103 is parallel to the extending direction of the adjusting groove 112101. The adjusting groove 112101 divides the connecting structure 1121 into two plug-in parts 11211, and the plug-in parts 11211 are arranged to be elastically deformable.

[0031] Specifically, when the connecting structure 1121 formed by the joint 112 moves in a direction of insertion into the mounting structure 3103, the two plug-in parts 11211 are pressed by the inner wall of the mounting structure 3103 to move close to each other, so as to move the connecting structure 1121 into the mounting structure 3103. In this way, after the connecting structure 1121 is assembled in the mounting structure 3103, the two plug-in parts 11211 are kept in abutment with the inner wall of the mounting structure 3103 under the action of elastic restoring force, and then the joint 112 is stably connected with the assembling component 31.

[0032] Alternatively, the mounting structure 3103 is implemented as a protrusion, and the connecting structure 1121 is implemented as a groove, and the principle is the same as the above embodiment, which is not described herein.

[0033] Specifically, each of the keel segments 111 has an insertion portion 1111, a mounting portion 1112, a pivot 1113 and an abutting portion 1114. The pivot 1113 is mounted to the insertion portion 1111, and the insertion portion 1111 extends along a direction perpendicular to an axis of the pivot 1113 to form the mounting portion 1112. The mounting portion 1112 forms a plug-in slot 111201, and the abutting portion 1114 is arranged at a bottom of the mounting portion 1112.

[0034] The keel segment 111 is plugged into the plug-in slot 111201 formed by the mounting portion 1112 of another keel segment 111 through the insertion portion 1111 arranged by itself, and the pivot 1113 mounted to the insertion portion 1111 is hinged to the mounting portion 1112 forming the plug-in slot 111201. The keel segment 111 is arranged to be able to rotate around the pivot 1113 arranged by itself towards a preset direction, and the abutting portion 1114 arranged by another keel segment 111 connected to the keel segment 111 is located on a rotation path of the keel segment 111 around the pivot 1113 arranged by itself towards a direction opposite to the preset direction.

[0035] In a preferred embodiment, each of the assembly components 31 includes three assembly pieces 311, and all the assembly pieces 311 are arranged in a stack from bottom to top. For the convenience of understanding, the three assembly pieces 311 from bottom to top are defined as a first assembly piece, a second assembly piece and a third assembly piece in sequence. The first assembly piece and the second assembly piece jointly form the first mounting space 3101, and the second assembly piece and the third assembly piece form the second mounting space 3102. Preferably, the first assembly piece forms the mounting structure 3103.

[0036] After the connecting structure 1121 formed by the joint 112 of each of the keel chains 11 is assembled to the mounting structure 3103 formed by the first assembly piece, the second assembly piece is pressed and assembled above the first assembly piece, so that the first assembly piece and the second assembly piece jointly fix the support mechanism 10; then after the end of the cable 21 is placed on an upper surface of the second assembly piece, the third assembly piece is pressed and assembled above the second assembly piece, so that the second assembly piece and the third assembly piece jointly fix the cable layer 20.

[0037] Further, the flexible dust-free drag chain further comprises two protective members 40, which are arranged in an upper and lower distribution. Each of the protective members 40 forms a plurality of insertion channels 401, wherein the keel chain 11 is inserted into the insertion channels 401 formed by the lower protective member 40, and the joint 112 of the keel chain 11 forms the connecting structure 1121 to extend out of the insertion channels 401, so as to facilitate the assembly of the connecting structure 1121 and the mounting structure 3103. The cable 21 is inserted through the insertion channels 401 formed by the upper protective member 40.

[0040] It is worth mentioning that the assembly mechanism 30 further comprises a sticking member 32, which is arranged between the inner wall of the second mounting space 3102 and the outer surface of the upper protective member 40. The upper protective member 40 is firmly mounted to the second mounting space 3102 through the sticking member 32, so as to prevent the cable layer 20 and the assembly component 31 from shaking.

[0041] In an example, the sticking member 32 is implemented as a rubber strip.

[0042] Preferably, the upper and lower surfaces of the assembly member 311 each form a receiving groove 31101, and the sticking member 32 is mounted to the receiving groove 31101, so as to avoid the occupation of the second mounting space 3102 by the sticking member 32, and to ensure that the second assembly member and the third assembly member can be tightly closed.

[0043] Preferably, the assembly member 311 comprises an assembly body 3111 and two side portions 3112. The two side portions 3112 are arranged in an opposite direction and are vertically extended from the assembly body 3111. The receiving groove 31101 is formed in the assembly body 3111, and the assembly body 3111 of the first assembly member forms the mounting structure 3103.

[0044] In an embodiment, the first assembly is assembled in a posture that the two side portions 3112 provided by the first assembly abut against the two side portions 3112 provided by the second assembly. The two side portions 3112 provided by the third assembly are pressed against the assembly body 3111 of the second assembly.

[0045] Further, the assembly mechanism 30 further comprises a plurality of fastening components 33, and the three assembly members 311 are connected by the fastening components 33. The fastening components 33 comprise a screw rod 331.
