Abstract

The invention discloses a lead guider, which is arranged below the back part of a transformer substation protection screen printer. The lead guider comprises a vertically arranged 'C'-shaped groove, wherein a guide hole is formed at the upper end of the 'C'-shaped groove; a slide block is arranged in the 'C'-shaped groove; a tension spring is arranged between the slide block and the lower end of the 'C'-shaped groove; a rotary shaft is fixedly arranged at the position of the slide block, which corresponds to an opening of the 'C'-shaped groove; a pulley capable of rotating on a vertical planeis arranged on the rotary shaft; a power line/a data line winds around the pulley and passes through the guide hole; the internal end of the pulley is screwed and fixed with the slide block; and a circular limit cap the diameter of which is more than the rotary shaft is arranged at the external end of the rotary shaft. The lead guider has a simple structure, practical functions and high reliability, is convenient to mount and use, does not cause a stagnation phenomenon in a using process, effectively overcomes the phenomenon of wrinkled printing paper or broken printing paper caused by unfixed positions of the data line and the power line of a printer, effectively shortens the printing time and improves the working efficiency.

Description

Wire lead guide

Technical field

The present invention relates to a kind of wire lead guide.

Background technology

All is furnished with printer on the protection screen of transformer substation; it is installed as shown in Figure 1; when using the printer 11 of protection screen 12; need to extract printer 11 out along the direction of arrow; printing pushes after finishing, and the power line of its back and data wire 13 easily disorderly, cause being placed on printing paper 14 folds behind the printer 11 or break in moving process; and can not use, impact is worked normally.

Summary of the invention

The object of the invention is to provide a kind of wire lead guide, can prevent because the mobile movement that drives power line and data wire of printer to the destruction that printing paper causes fold or breaks, has improved operating efficiency.

To achieve these goals; the present invention adopts following technical scheme: wire lead guide; be arranged on the back lower place of protection screen of transformer substation printer; " C " type groove that comprises vertical setting; the upper end of " C " type groove is provided with pilot hole; be arranged with slide block in " C " type groove; be provided with tension spring between slide block and " C " type groove lower end; aperture position corresponding position with " C " type groove on the slide block is fixed with rotating shaft; rotating shaft is provided with the pulley that can rotate at vertical plane, and power line/data wire is walked around pulley and passed the pilot hole setting.

Described rotating shaft the inner and slide block are spirally connected fixing, and the outer end of rotating shaft is provided with diameter greater than the circular limited cap of rotating shaft.

The present invention is simple in structure, practical function, easy for installation, easy to use, reliability is high, catching phenomenon did not in use appear, the data wire and the power cord location that efficiently solve printer fixedly do not cause printing paper fold or fracture phenomena, effectively shorten the time-write interval, improved operating efficiency.

Embodiment

Embodiment: shown in Fig. 2-6; wire lead guide; be arranged on the back lower place of protection screen of transformer substation 12 printers 11; " C " type groove 1 that comprises vertical setting; the upper end of " C " type groove 1 is provided with pilot hole 2; be arranged with slide block 5 in " C " type groove 1; be provided with tension spring 6 between slide block 5 and " C " type groove 1 lower end; aperture position corresponding position with " C " type groove 1 on the slide block 5 is fixed with rotating shaft 4; rotating shaft 4 is provided with the pulley 3 that can rotate at vertical plane, and power line/data wire 13 is walked around pulley 3 and passed pilot hole 2 and arranges.Rotating shaft 4 the inners and slide block 5 are spirally connected fixing, and the outer end of rotating shaft 4 is provided with diameter greater than the circular limited cap of rotating shaft.

Pilot hole 2 is fixed on the top of " C " type groove 1, and slide block 5 is stuck in " C " type groove 1, by spring 6 with " bottom of C type groove links to each other, and axle 4 is fastened on the slide block 5, and pulley 3 is enclosed within on the axle 4.

During use; two wire lead guide can be set; wire lead guide is fixed on the both sides of protection screen by " C " type groove 1 with screw; (power line of printer and data wire are respectively in the both sides of printer 11 usually to be used for respectively guiding power line and data wire; as in a side; then two wire lead guide can be fixed on the same side), power line/data wire 13 is passed in the groove that pilot hole 2 places pulley 3.When printer is not pulled out, tension spring 6 places of wire lead guide nature relaxed state.

During when the need printing and along the existing printer of arrow Fang Xianla, power line/data wire 13 moves up by pilot hole 2 band movable pulleys 3, and tension spring 6 is tightened up.

Print completely when pushing printer 11, under the effect of tension spring 6, pulley 3 moves down, and moves down thereby drive power line/data wire 13.

Under the effect of pilot hole 2 and pulley 3; no matter printer 11 is pulled out or is pushed; power line/the data wire 13 of printer all can move along fixing path in the both sides of protection screen, can not draw close to the centre, thereby can the paper feed of printer printing paper 14 not impacted.

Claims

1. wire lead guide; it is characterized in that: the back lower place that is arranged on the protection screen of transformer substation printer; " C " type groove that comprises vertical setting; the upper end of " C " type groove is provided with pilot hole; be arranged with slide block in " C " type groove, be provided with tension spring between slide block and " C " type groove lower end, the aperture position corresponding position with " C " type groove on the slide block is fixed with rotating shaft; rotating shaft is provided with the pulley that can rotate at vertical plane, and power line/data wire is walked around pulley and passed the pilot hole setting.

2. wire lead guide according to claim 1 is characterized in that: described rotating shaft is inner to be spirally connected fixingly with slide block, and the outer end of rotating shaft is provided with diameter greater than the circular limited cap of rotating shaft.
