Detailed description of the invention
With specific embodiment, the utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of self-locking slow rolling chi.
Fig. 2 is the structural representation after left outside shell removed by self-locking slow rolling chi.
As depicted in figs. 1 and 2, self-locking slow rolling chi includes: chi box the 100th, reeler the 200th, damper the 300th, chi bar 400 and
Lanyard 500.
Chi box 100 includes: left outside shell the 110th, right casing the 120th, chi Tiaokou the 130th, button slot 14 and suppending hole 150.
The left outside shell of hollow the 110th, right casing 120 passes through the connection of screw or buckle, forms the main body of chi box 100.Left outside
The corresponding position of shell the 110th, right casing 120 has groove, forms chi mouth 130 and button slot 140 after being fixed together.Chi bar 400
Pass in and out chi box 100 from chi Tiaokou 130.The button assembly 310 of damper 300 is arranged on button slot 140.Lanyard 500 is suspended on
It on suppending hole 150, is convenient for carrying and uses self-locking slow rolling chi.Chi box 100 is internal can accommodate reeler the 200th, damper 300
With chi bar 400.
Chi bar 400 one end is connected with reeler 200, passes through chi Tiaokou 130, and the other end has chi hook.When chi bar 400 is complete
During full entrance chi box 100, chi hook catches on the outside of chi Tiaokou 130, fixes this position.
Reeler 200 is arranged on the centre position of chi box 100, drives chi bar 400 to be automatically involved in chi box 100.
Damper 300 includes: the 330th, button assembly the 310th, damping ball the 320th, swingle damps rotary shaft 340 and reset bullet
Spring 350.
The centre position of swingle 330 is arranged in damping rotary shaft 340, can rotate around damping rotary shaft 340.Damping ball
320 one end being arranged on swingle 330, are close to reeler 200.Other end next-door neighbour's chi Tiaokou 130 of swingle 330.Reset bullet
Spring 350 one end is arranged on the side near chi Tiaokou for the swingle 350, and the other end is arranged on chi box 100.
Button assembly 310 includes: friction mandrel the 311st, button rotation axle 312 and button 313.
Button 313 is arranged on the button slot 140 of chi box 100, and button 313 one end is arranged on button rotation axle 312, can
Rotate around button rotation axle 312.The other end of button 313 is fitted near the side of damping ball 320 with swingle 350.
The circumference of button rotation axle 312 circumference laminating friction mandrel 311, reduces frictional force when button 313 rotates.
The course of work of self-locking slow rolling chi:
In the state of button does not has active force:
Under the effect of back-moving spring, swingle one end exerts a force downwards, and chi bar is pressed in the exit of chi Tiaokou, now chi
Bar cannot move.
Fig. 3 is the force diagram of self-locking slow rolling chi contraction ga(u)ge bar original state.
When needs shrink tape measure: as it is shown on figure 3, operator touches the button downwards, button rotation is by the other end of swingle
Move to reeler, drive damping ball to press to reeler；Simultaneously swingle around damping rotary shaft rotate, the other end of swingle to
Upper movement, cancels the pressure on chi bar, and chi bar, under the effect of reeler, shrinks automatically.
When reeler has just started footage bar, on reeler, chi bar is less, and diameter is also relatively small, with damping ball not in contact with or
Person's contact is less.
Fig. 4 is the force diagram of self-locking slow rolling chi contraction ga(u)ge bar later stage state.
As shown in Figure 4, the chi bar on reeler is rolled up bigger and bigger, and the diameter of reeler is also increasing, with damping ball
Between frictional force also increasing, damping ball stress counter motion, be rotated bar rotate, the other end of swingle is increasingly
Move down, increasing with the chi bar frictional force shunk, reduce the speed that chi bar shrinks.
