Disclosure of Invention
The invention aims to: to the problem that above-mentioned exists, provide a three-dimensional drag chain link, through to dragging the ingenious design of chain link structure, each part is mutually supported and is used, can reach convenient dismantlement installation, can also make the tow chain can form confined annular cable accommodation space, the effectual easy exposed phenomenon of avoiding the cable take place, its simple structure, performance is good.
The technical scheme adopted by the invention is as follows:
The invention relates to a three-dimensional drag chain link, which comprises a connecting middle shaft and a plurality of guide ring pieces annularly arranged outside the connecting middle shaft, wherein the connecting middle shaft is used for the serial connection of adjacent drag chain links; each guide ring piece is connected with the connecting middle shaft through a cross beam and is connected into a ring shape; the crossbeam is connected on the circumference lateral wall of connecting the axis, cuts apart the annular space that the direction ring piece formed into the space that runs through of a plurality of cables.
Due to the adoption of the structure, the plurality of guide ring pieces which are annularly arranged outside the circumference of the connecting middle shaft are respectively provided with the position of one end of the guide ring piece limited by the cross beam, the other end of each guide ring piece is in closed connection with the end part of the guide ring piece which is adjacently installed, the guide ring pieces can be completely disassembled with the internal mechanism, when the drag chain is installed, the guide ring pieces can be installed after the connection of the middle parts of the guide ring pieces inside the drag chain is completed, the installation is higher, the disassembly and the installation are both convenient, the guide ring pieces which are locally damaged can be locally replaced, the maintenance and treatment time of the drag chain is greatly saved, the use flexibility of the drag chain is strong, the structure is simple, and the drag chain has good use value and.
According to the three-dimensional drag chain link, at least three guide ring sheets are arranged, and each guide ring sheet is correspondingly connected to a cross beam matched with the guide ring sheet; each guide ring piece is connected end to end, and the cross beams are uniformly distributed on the circumferential outer wall of the connecting middle shaft and are fixedly connected with the connecting middle shaft.
Furthermore, the guide ring piece is of an arc-shaped structure, and a connecting column is arranged at the connecting end part of the cross beam and the guide ring piece; the end part of the guide ring piece is provided with a clamping hook which is arranged corresponding to the connecting column, and the clamping hook is installed in a matched mode with the connecting column and can rotate in a certain range relative to the connecting column.
Furthermore, a branch part is arranged at the other end part of the guide ring piece relative to the clamping hook; adjacent to the clamping hook, a notch is arranged on the guide ring piece, and the notch can be connected with a branch part on the adjacent connected guide ring piece in a sealing way.
Furthermore, the clamping hooks on the branch parts and the adjacent connected guide ring pieces are staggered with each other at the notches to form the guide ring with uniform width.
Owing to adopt above-mentioned structure, the stability of relative hookup location is realized to the structure of accessible bolt between the guide ring piece, because the tow chain generally adopts the plastics material that has certain plasticity, but through extrusion erection joint adjacent guide ring piece, and adopt the structure cooperation installation of spliced pole and trip between guide ring piece and the crossbeam, make the rotation of realizing the minizone in the guide ring piece installation, thereby make the trip can be quick smoothly change to join in marriage with the spliced pole cooperation, also can be further make things convenient for the connection on another tip of guide ring piece.
According to the three-dimensional drag chain link, the two ends of the connecting middle shaft are respectively provided with the clamping boss and the clamping groove, the clamping boss in the adjacent connected drag chain link is matched with the clamping groove, and the central line of the clamping boss is matched with the central line of the connectable groove by pressing and extruding the clamping boss into the clamping groove.
Further, the joint boss is spherical boss, the diameter of the installation import department of joint recess is less than the diameter of joint boss.
Or, the clamping groove can be a through arc-shaped clamping ring structure.
Owing to adopt above-mentioned structure, joint boss accessible is connected the boss in connecting epaxial for the connecting piece that the boss size is littleer to can be more convenient fill in the boss joint in the joint recess joint, and guarantee the stability of its structure, avoid the joint boss to take off the phenomenon emergence of the joint recess, make the drag chain can be random in the use rotate buckle and do not influence the normal use of equipment.
According to the three-dimensional drag chain link, the opening direction of the clamping groove is opposite to the direction of the spherical clamping boss.
By adopting the structure, the connection with the mutually staggered connection parts is formed, so that the drag chain links can be mutually restricted after being connected into a string, and the stability of the structure is further ensured.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. The three-dimensional drag chain link has simple structure and high mounting and dismounting efficiency;
2. The annular closed guide ring can effectively prevent the wire wheel from jumping out and ensure the installation effect on the cable;
3. The structure stability is good, and the formed drag chain has strong flexibility;
4. the maintenance/repair cost of the equipment is low, and the efficiency is high;
5. the practicability is strong.
