Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings. Only this statement, the utility model discloses the upper and lower, left and right, preceding, back, inside and outside etc. position words that appear or will appear in the text only use the utility model discloses an attached drawing is the benchmark, and it is not right the utility model discloses a concrete restriction.

Example 1

A power line resistant to pulling is shown in figures 1, 2, 3, 4, 5 and 6 and comprises a first connecting end 1, a first connecting block 2, a fixing block 3, a connecting line 5, a second connecting end 9 and a resistant to pulling mechanism, wherein the first connecting end 1 is provided with the connecting line 5, the first connecting block 2 is fixedly connected to the periphery of the connecting position of the connecting line 5 and the first connecting end 1, the first connecting block 2 is provided with the three fixing blocks 3, the second connecting end 9 is installed at one end, far away from the first connecting end 1, of the connecting line 5, and the resistant to pulling mechanism is arranged inside the connecting line 5.

As shown in fig. 5 and 6, the anti-pulling mechanism includes a braided wire 10, a protective rubber sleeve 11, an insulating layer 12 and a copper wire 13, the braided wire 10 is connected to the inner side of the connecting wire 5, the protective rubber sleeve 11 is arranged on the inner ring of the braided wire 10, the insulating layers 12 are arranged on the inner side of the protective rubber sleeve 11, and the copper wire 13 is arranged inside each insulating layer 12.

As shown in fig. 1, fig. 3, fig. 4 and fig. 5, the connecting device further comprises a second connecting block 6, a connecting plate 7 and a fixing ring 8, the periphery of the joint of the connecting line 5 and the second connecting end 9 is connected with the second connecting block 6, three connecting plates 7 are fixedly connected to the second connecting block 6 through bolts at even intervals, three fixing rings 8 are jointly arranged on the inner sides of the connecting plates 7, and the inner sides of the fixing rings 8 are connected with the connecting line 5.

In this power cord, at first every group copper line 13 periphery in connecting wire 5 cup joints insulating layer 12, then at a plurality of copper line 13 outer lane parcel one deck protection gum cover 11 that have insulating layer 12, protection gum cover 11 has certain extending performance, can play certain stretch-proofing effect of preventing fracture, cup joint the braided wire 10 that has stronger toughness in protection gum cover 11 outside afterwards, intensive braided wire 10 has toughness than general gum cover more, that is to say, braided wire 10 has certain stretch-proofing performance, so just can play the effect that prevents the power cord because pull and direct fracture gum cover exposes power cord inner structure, sheathe connecting wire 5 in the braided wire 10 outside again. After the internal structure of the connecting wire 5 of the power line is assembled, the end part of the connecting wire 5 for current input is fixedly connected with three fixed blocks 3 uniformly at intervals, the three fixed blocks 3 are flush with the ports of the connecting wire 5, the three fixed blocks 3 and the end part of the connecting wire 5 are connected with a first connecting block 2 together, and the first connecting end 1 for plugging a power socket is connected onto the first connecting block 2.
