Description

Single stay two-orbit line stretcher box

Technical field:

The utility model relates to a kind of line stretcher box, refers specifically to a kind of single stay two-orbit line stretcher box.

Background technology:

Existing line stretcher box has two-wire to stretch and single line stretches two kinds; single stay line stretcher box often stuck phenomenon can occur in the course of the work; to such an extent as to increased the number of times that stretches; therefore single stay line stretcher box is easily drawn bad; although and two backguy line stretcher box has solved the phenomenon that is stuck when stretching; but winding box can be in the midway location of operating side and control end in the process that stretches, and not only affects attractive in appearancely, and can have a strong impact on service life of line stretcher box.

The utility model content:

In order to solve the problem that exists in the above technical field, the utility model proposes following art solution.

The utility model is by lower house, law, the reel drain pan, the spiral wheel cap, dual track, ball, upper shell, center bolt, rotating shaft, law outer end hold down groove, the inner hold down groove of law, line outlet, form with spool, inboard centre bit at lower house is equipped with a rotating shaft, the middle part of rotating shaft has the inner hold down groove of law, the law middle part is penetrated rotating shaft, the inner termination of law is embedded in the inner hold down groove of law, allow law sink to the bottom of lower house inboard, the reel drain pan is installed on law, a law outer end hold down groove is arranged in the outer of reel drain pan, central part has a spool above it, the outer end of law is hooked in the hold down groove of law outer end, with the reel drain pan to pressing down, until with the lower house button box, when a little, law just is fixed in the housing of formation of lower house and reel drain pan.The spiral wheel cap is installed on the reel drain pan, and the spiral wheel cap is embedded in by its centre hole on the spool of reel drain pan, forms a double-tee reel with the reel drain pan, and data line is just on reel.

Data line on the reel, its inner are fixed on the column on spool next door, and pull out from line outlet its outer end, and when data line was drawn out, reel was drawn and rotates, and at this moment law is tensioned, and has produced the potential energy of contraction data line.

Dual track is installed on the spiral wheel cap, and dual track and spiral wheel cap are fixed in one, and both do not do any displacement each other, and whirlpool groove A and whirlpool groove B are arranged at the middle part of dual track, and whirlpool groove A and whirlpool groove B are the transitional slots that switches tracks of dual track.On dual track upper shell is installed, upper shell and lower house fasten, and screw up with center bolt by rotating shaft.

In the process that data line is being pulled out, as long as one stops drag, ball will sink in one of them whirlpool groove of A, two whirlpool grooves of B, under the effect that does not have other external force, ball sinks to the lowest part of whirlpool groove, can automatically not roll out whirlpool groove injection, when again spurring data line, if the pulling amplitude is too large, ball just rolls out the whirlpool groove along the direction of pulling, and data line is drawn out; If only spur when decontroling again, because the effect of inertia, ball will roll out the whirlpool groove along reversing sense, and data line is retracted.

The beneficial effects of the utility model are by increasing the orbit of a reel, reel is operated steadily in order, and the partition running of line is very steady, and not only feel is soft, and is difficult for the corrupt data line, and the use that has effectively prolonged product is received the order.

Description of drawings:

Figure is exploded view of the present utility model.

The specific embodiment:

Such as figure, the utility model comprises lower house 1, law 2, reel drain pan 3, spiral wheel cap 4, dual track 5, ball 6, upper shell 7, center bolt 8, rotating shaft 9, law outer end hold down groove 10, the inner hold down groove 11 of law, line outlet 12, form with spool 13, inboard centre bit at lower house 1 is equipped with a rotating shaft 9, the middle part of rotating shaft 9 has the inner hold down groove 11 of law, law 2 middle parts are penetrated rotating shaft 9, the inner termination of law 2 is embedded in the inner hold down groove of law, allow law 2 sink to the bottom of lower house 1 inboard, reel drain pan 3 is installed on law 2, a law outer end hold down groove 10 is arranged in the outer of reel drain pan 3, central part has a spool 13 above it, the outer end of law 2 is hooked in the law outer end hold down groove 10, with reel drain pan 3 to pressing down, until with lower house 1 button box, when a little, law 2 just is fixed in the housing of lower house 1 and the formation of reel drain pan 3.Spiral wheel cap 4 is installed on reel drain pan 3, and spiral wheel cap 4 is embedded in by its centre hole on the spool 13 of reel drain pan 3, forms a double-tee reel with reel drain pan 3, and data line is just on reel.

Dual track 5 is installed on reel, whirlpool groove A and whirlpool groove B are arranged at the middle part of dual track 5, whirlpool groove A and whirlpool groove B are the transitional slots that switches tracks of dual track.Upper shell 7 is installed on dual track, and upper shell 7 fastens with lower house, screws up by rotating shaft 9 usefulness center bolts 8.
