Binary channel binding bandTechnical field: the utility model relates to a kind of binding band tying up cable.
Background technology: in building, many fields such as electric, all needs to use binding band to tie up cable, keeps circuit neat.General nylon binding band comprises snap close head and belt body, the free end of belt body through snap close head groove and and elastic card fastener frictional fit, to tighten cable.But the groove in snap close head only has one, belt body can only once pass, and the length great quantities of spare of belt body is slatterned, and the mode of tying up of once passing is single, cannot wear continuously around, tie up by force intensity also undesirable.
Summary of the invention: for the deficiencies in the prior art, the utility model provides one to tie up mode novelty, the binary channel binding band that belt body degree of utilization is high.
The utility model comprises belt body and is connected to the snap close head of belt body one end, and be provided with elastic card fastener and threading channel in snap close head, elastic card fastener and threading channel all have two, and the bearing of trend along belt body in snap close head is independently arranged.
Elastic card fastener of the present utility model and threading channel all have two, when tying up, belt body can also be tied up through another passage through after a passage again, it is novel reliable that threading ties up mode, force structure is reasonable, also not easily slippage or fracture when pullling energetically, tie up load intensity greatly to improve, and make the length of belt body obtain more fully using.
The utility model is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the left view of Fig. 1.
Fig. 3 be embodiment tie up using state schematic diagram.
Detailed description of the invention: as depicted in figs. 1 and 2, snap close head 1 is connected to one end of belt body 2, be provided with elastic card fastener 3 and threading channel 4 in snap close head 1, elastic card fastener 3 and threading channel 4 all have two, independently arrange in snap close head 1 along the bearing of trend of belt body 2.Two threading channel 4 in the present embodiment are adjacent, and two elastic card fasteners 3 are connected on the inwall in snap close head 1 liang of outside, and the free end of two elastic card fasteners 3 is towards the opposite.Such structure is rationally more convenient during fabrication, is conducive to one-body molded, and two elastic card fasteners 3 towards the opposite are more convenient for, the around the bundle of wearing continuously of belt body 2 is pricked.
During use, as shown in Figure 3, surround Part I cable to be tied up with belt body 2, and by first groove 4 of the free end of belt body 2 through snap close head 1, make elastic card fastener 3 contact friction in belt body 2 and first groove 4 and strain, Part I cable can be bound.Then, the residue length of belt body 2 can also surround Part II cable to be tied up, and by second groove 4 of the free end of belt body 2 through snap close head 1, make elastic card fastener 3 contact friction in belt body 2 and second groove 4 and strain, Part II cable can be bound.
In fact, can gather at the back side of belt body 2 and be provided with unidirectional helical teeth 5, also correspondingly on the corresponding contact surface of each elastic card fastener 3 be provided with unidirectional helical teeth 5 and coordinate, such binding band is unidirectional, and to tighten performance better, strengthens further tying up strength, use more reliable.
