Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described with specific embodiment.
Embodiment one
As shown in Figure 1, Figure 2 and Figure 3, centrifugal slow winding chi includes：Chi box 100, reeler 200 and four centrifugation parts
300。
Chi box 100 includes：Left outside shell 110 and right casing 120.Hollow left outside shell 110, right casing 120 by screw or
The connection of buckle, forms the main body of chi box 100.
Left outside shell 110 has rotary shaft 111.The centre bore of reeler 200 is enclosed within rotary shaft 111, realizes reeler 200
With being rotatably connected for chi box 100.
Reeler 200 has side plate 210.Circumference uniform distribution has 4 eccentric grooves 211 on side plate 210.Each eccentric groove 211
One end all point to the rotary shaft 111 of reeler 200.Each eccentric groove 211 is made up of the dividing plate of two evaginations.Four from
Central member 300 is cylinder, is separately positioned in 4 eccentric grooves 211.Centrifugation part 300 is slightly shorter than the length of eccentric groove.
The inner side of right casing 120 has circular damping slot 121.Centrifugation part 211 is arranged in damping slot 121 simultaneously.
The course of work of centrifugal slow winding chi：
During the 200 contraction ga(u)ge bar of reeler of tape measure, rotate around rotary shaft 111.With the rotation of reeler 200, it is arranged on
The centrifugal force that cylinder centrifugation part 300 on the side plate 210 of reeler 200 is subject to, moves in eccentric groove 211, can be away from rotation
The circus movement of rotating shaft 111, clashes into the circumferential inner wall of the damping slot 121 on right casing 120.Between centrifugation part 111 and damping slot 121
Frictional force is produced, reduces the rotary speed of reeler 200.
When the speed of the rotation of reeler 200 is faster, the frictional force that part 111 and damping slot 121 is centrifuged is bigger, and slowing effect is got over
Substantially.After the rotary speed of reeler 200 is reduced or stopped, centrifugation part 111 is reduced or stopped and produces and damping slot 121 between
Friction, reeler 200 normally rotates, and realizes the rotary speed of fully automated regulation reeler 200, prevents reeler 200 from rotating
The phenomenon of too fast and caused chi bar hired roughneck occurs.
Variation
Centrifugation part and eccentric groove quantity in the centrifugal slow winding chi of embodiment one is 4.As shown in figure 4, in practice
Can arrange 1 to 6, it is of course possible to which greater number is set according to the speed of reeler rotation or specific demand.
In addition, centrifugation part can be arranged on the one or both sides of reeler, or it is not set directly on reeler, passes through
Miscellaneous part is realized being rotated with reeler.
