Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
As shown in Figures 1 to 5, this plane rolling covered wire frame comprises three supports 50, each support 50 includes feet 51, strut bar 52, pipe link 53, mount pad 54, the respective one end of three pipe links 53 is installed on corresponding feet 51 respectively, the other end weld together between two that three pipe links 53 are respective, the end of each strut bar 52 is all installed on corresponding pipe link 53, each mount pad 54 is installed between corresponding strut bar 52 head end and corresponding feet 51 head end, each mount pad 54 is all rotatably mounted with a rolling rod 55, side plate 61 is all welded with between adjacent two feet 51 ends, this plane rolling covered wire frame also comprises the first holder 70, second holder 80, base plate 62, first holder 70 is arranged between one of them strut bar 52 and corresponding feet 51, second holder 80 is arranged on the lateral wall of one of them pipe link 53, base plate 62 is vertical with three side plates 61 respectively to be arranged, base plate 62 respectively with three feets 51, three side plates 61 weld and around formation collet box 60.It is worth mentioning that, each rolling rod 55 all can around hinge-point 360 ° of axial rotation of corresponding mount pad 54, and the upper end surface of three rolling rods 55 is in same circumferential rotational plane.
This plane rolling covered wire frame in an initial condition, shown in composition graphs 1, the cable 11 of shaping rear longer dimension is first coiled into coil of cable 10 by operator, coil of cable 10 is hollow structure, and it is well-known, a cable 11 has lateral wall and the madial wall that two the end of a thread, 111, two the end of a thread 111 lay respectively at coil of cable 10.Multiple cap sleeve 20, certification of fitness 30, self-adhesive film volume 40 is placed with respectively in the first holder 70, second holder 80, base plate 62 (collet box 60), coil of cable 10 is shelved on this plane rolling covered wire frame, concrete, coil of cable 10 is shelved on three supports 50, and the lower surface of coil of cable 10 is resisted against on the upper surface of three rolling rods 55.In addition, self-adhesive film volume 40 is wound by self-adhesive film and self-adhesive film does not scribble glue, and self-adhesive film is chosen as the transparent body.
In this case, the packaging process of coil of cable 10 is as follows: first, and operator picks up two the end of a thread 111 and adopts pyrocondensation sealing cap mode on two the end of a thread 111, overlap cap sleeve 20 respectively, and cap sleeve 20 also secures with corresponding the end of a thread 111 by homogeneous heating the end of a thread 111; Secondly, the end of a thread 111 is replaced, and at least one cord is fastened on coil of cable 10, to prevent the end of a thread 111 from dropping, and then certification of fitness 30 is wrapped on coil of cable 10 lateral wall by the transparent self-adhesive film (not shown) winding on self-adhesive film volume 40; Finally continue to be wound around parcel coil of cable 10 until entire package is complete with transparent self-adhesive film.
Above-mentioned structure design, make the end of a thread 111 place fixed, not loose, do not get loose, cable 11 end socket is smooth and firmly, cap sleeve 20 has waterproof efficacy, can guarantee to play the not loose and sealing function of 11, cable.
Now use 360 ° of plane rolling covered wire frames instead, that is to say that coil of cable 10 can realize 360 ° and horizontally rotate under three rolling rods 55 drive, do not need wire rod to lift when envelope curve, circumference is only needed to rotate coil of cable 10, bring light greatly to operator, respond well, suitable repetitive cycling uses, and improves work efficiency.
Self-adhesive film adopts glue-free setting and quality is light, can firmly fit together with affixed object enduringly.When taking off this self-adhesive film, only need uncover from the edge of film, just can easily easily self-adhesive film be peeled.The self-adhesive film of multiple wraps can also play protective action, can meet storage and adapt to long-distance transport requirement.
The setting of certification of fitness 30, reasonable in design and structure is simple, coil of cable 10 is identified clear and correctly unique, guarantees to realize product back-tracing.
Further preferably, the angle between adjacent two pipe links 53 is 120 °.Equally spaced design, makes three supports 50 support more firm, reasonable in design and good stability.
Preferably, the first holder 70 is by five the first flat boards 71 around surrounding, and adjacent two first flat boards 71 are all vertically arranged, and the shape of cross section of the first holder 70 is rectangle.The first holder 70 like this can be used for placing the cap sleeve 20 of a greater number, reasonable in design and structure simple, easy to process.
Preferably, second holder 80 by two second flat board 81, two the 3rd flat boards 82 around surrounding, two second flat boards 81 be arranged in parallel and vertically with each 3rd flat board 82 respectively to arrange, and two the 3rd dull and stereotyped 82 are arranged in an angle, and the shape of cross section of the second holder 80 is triangle.Because certification of fitness 30 is thin paper sheet, such second holder 80 can handled easily workman to be taken certification of fitness 30, avoids occurring that certification of fitness 30 is adsorbed on bottom and takes the situation of not coming up.
Preferably, each feet 51 end is all provided with roller, and roller makes whole covered wire frame to move, and reasonable in design and structure is simple, and Assembly &Disassembly is all more convenient, and this plane rolling covered wire frame is easy to carry.
Wherein, support of the present invention comprises following composition and parts by weight thereof: resin: 100 parts, fire retardant: 7-15 part, curing agent: 1-5 part, accelerator: 1-5 part, ultraviolet absorber: 5-10 part, filler: 20-40 part.
