Abstract
The utility model relates to a drawing-assembling type personal security line which belongs to the field of electrostatic technology and is provided with a short route, one end of which is connected with a grounding nut and the other end of which is connected with a clamp shell, provided with a telescopic hook. When the telescopic hook is pulled out, a slider and a block arranged in the inner side of the telescopic hook could be positioned through a fixture hook block arranged in the clamp shell. When continuing to pull the telescopic hook outside, the telescopic hook is retracted with the role of spring. When the utility model is put into practice, the grounding nut is connected with an exposed bolt of the transmission pylon and the telescopic hook clamps a wire, effectively preventing the power supply enterprise workers from the high-voltage static electricity injury when in maintenance or in construction.
Description
Technical field
The utility model relates to a kind of pulling type individual security personnel line that belongs to the electrostatic technique field.
Background technology
At present, the operating personnel of power supply enterprise subjects to the injury of the static that induced voltage exists at parallel circuit, with the lead of shaft tower and stringing road, newly-built circuit when maintenance and construction operation.According to the requirement of new " electrical safe working order " issued of State Grid Corporation of China, this problem must solve, and present power supply enterprise does not have the purpose-built security appliance of this respect.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of and can effectively prevent static guarantee the to power pulling type individual security personnel line of operating personnel's safety for solving disadvantages of background technology.
The purpose of this utility model is achieved in that it is provided with short-circuit line, short-circuit line one end is connected with the grounding nut overcoat, be provided with grounding nut in the grounding nut overcoat, the short-circuit line other end is connected with the wire clamp shell, be provided with frid in the wire clamp shell, the inner of the retractable hook that is provided with is inserted the wire clamp shell and can be slided in frid, be fixed with slide block and block in retractable hook the inner, be provided with a grab piece in the wire clamp enclosure, grab piece one end is fixed by rotating shaft and wire clamp shell, be provided with spring leaf between grab piece downside and the wire clamp shell, the middle part of grab piece upper side is provided with a wedge-shaped projection, and slide block on the retractable hook and block can slide at grab piece upper side also can block wedge-shaped projection, is provided with a spring in the wire clamp enclosure, spring one end and wire clamp shell are fixed, and its other end and retractable hook are inner fixing.
Described grounding nut is the ground connection inner nut.
The utility model is compared background technology and had following advantage: 1. easy to use, the utility model one end blocks lead, and an end is connected with electric power pylon exerted bolt head and gets final product; 2. whole security personnel's line is in light weight, carries very convenient; 3. ground connection is effective, can prevent the static injury effectively.
Description of drawings
Fig. 1 is the utility model structure principle chart.
Embodiment
The utility model is further described by embodiment below in conjunction with accompanying drawing: as shown in Figure 1, ground connection inner nut 2 is connected with short-term 3 by grounding nut overcoat 1, short-circuit line 3 is connected with wire clamp shell 6 with end line bolt 5 by end line nose 4, and retractable hook 12 can slide at the frid 11 of wire clamp shell 6 inside.Trip piece 8 is fixing by rotating shaft 14, and its underpart is provided with spring leaf 7.Operation principle of the present utility model is: pull out retractable hook 12 (Fig. 1 pulls out state as retractable hook) when using, slide block 10 on the retractable hook 12 and block mounting board 13 this moment are lived the wedge-shaped projection on the trip piece 8 and are located, when treating that retractable hook 12 is clamped the lead of static, after out-draw was contracted and colluded 12, retractable hook 12 was clamped lead in the effect of spring 9.The ground connection inner nut 2 of the other end of short-circuit line 3 is screwed in the iron tower exerted bolt and gets final product.Can effectively prevent the high-pressure electrostatic casualty accident when operating personnel maintenance or construction line like this.
Claims (2)
