Embodiment
In order to which the utility model is better described, it is explained with reference to the accompanying drawings.
Fig. 1 illustrates the embodiment of the utility model one, and schematic diagram during stationary state is in which show handle.According to figure
Shown in 1, commutation latch 1 is removably fixed in chute 7 by screw.3 be lock panel.Handle body 4 passes through lock panel 3
Grip hole is coupled with reversing arrangement 2.Commutation latch 1 is placed in the chute 7 of lock panel 3, is pushed down with fixed screw.Change
To latch 1 in the presence of spring 5, compressed with reversing arrangement 2；The projection 21 of either reversing arrangement stretches into commutation latch 1
In fixing hole 12.Now handle assembly can not commutate.Now commutation latch 1 is also in close contact with chute 7, between the two will not phase
To sliding.
Fig. 2 shows the schematic diagram when embodiment handle of the utility model one is in commutation states.Spring 5 is compressed, and is changed
It is in and retracts under state in chute 7 to latch 1, is completely separated between reversing arrangement 2 and commutation latch 1.Reversing arrangement 2 can edge
The direction of arrow shown in figure rotates 180 degree, so as to realize that handle commutates.
Fig. 3 shows the embodiment of the utility model one, during in stationary state, commutation latch and chute relation partial enlargement
Figure.Commutation latch 1 and reversing arrangement 2 couple.Now, commutate tight between the side 1 of latch 1 and the medial surface 1 of chute 7
Contiguity is touched, and is in close contact between the side 2 11 ' for the latch 1 that commutates and the medial surface 2 71 ' of chute 7.As seen from the figure,
The cross section of commutation latch 1 is trapezoidal, and chute 7 limits a trapezoid space.
Fig. 4 shows the embodiment of the utility model one, during commutation states, commutation latch 1 and the relation partial enlargement of chute 7
Figure.Reversing arrangement 2 and its projection 21 are separated with commutation latch 1 completely.Now, handle assembly can freely be commutated.
Now, commutating between the side 1 of latch 1 and the medial surface 1 of chute 7 has a fixed gap, and the side for the latch 1 that commutates
2 11 ' there is a fixed gap between the medial surface 2 71 ' of chute 7.The presence in these spaces, it can to commutate latch 1 just
Often pull out unrestricted with withdrawal.
Fig. 5 be according to the embodiment of the utility model one, during stationary state, the longitudinal sectional drawing of commutation latch 1 and chute 7.
The projection 21 of reversing arrangement is stretched into the fixing hole 12 of commutation latch 1.Now, handle is for lock-out state, it is impossible to commutates.
Fig. 6 shown according to the embodiment of the utility model one, during commutation states, the longitudinal profile of commutation latch 1 and chute 7
Figure.Spring 5 further compresses, and commutation latch 1 is for retracted mode.Fixing hole of the projection 21 of reversing arrangement from commutation latch 1
Extracted in 12.Now, handle assembly can realize commutation.
Fig. 7 is shown according to the embodiment of the utility model one, the structural representation of commutation latch 1 and handle assembly.Handle
Body 4 couples with reversing arrangement 2, and commutation latch 1 controls the whether rotatable state of reversing arrangement 2.In normal state, spring
5 can produce an active force that commutation latch 1 is pushed away towards reversing arrangement 2.Thus, in general, commutation latch 1 locks
Reversing arrangement 2, prevent it from commutating.When needing commutation, by the handle 13 on latch 1 that commutates toward pulling back, so that changing
To device raised 21 from commutation latch 1 fixing hole 12 in extract, now can be carried out handle and commutate.
Fig. 8 is shown according to the embodiment of the utility model one, the structural representation of commutation latch 1.Set on commutation latch 1
There are handle 13,14 fixed columns of fixed spring 5, the fixing hole 12 stretched into for the projection 21 of reversing arrangement.
Fig. 9 is shown according to the embodiment of the utility model one, the structural representation of reversing arrangement 2.Reversing arrangement 2 is in annulus
Shape.It has a pair of projections 21.The center of circle that annulus is passed through to the line between projection 21.This way it is ensured that in reversing arrangement 2
After rotating 180 degree, a projection 21 still can be fixed by stretching into the fixing hole 12 of commutation latch 1.
Above-described embodiment describes merely by way of example.Limited without departing from the appended claims for the utility model
Protection domain in the case of, can have various variants.
