The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 A, Fig. 4 B, Fig. 5, Fig. 6 A, Fig. 6 B, Fig. 6 C, Fig. 6 D and shown in Figure 7, the ratchet spanner of this case roughly comprises: a body (10) has a lever (12); One ratchet (40), it is disposed in this body (10) and has the plurality of pins (42) of a circumference that defines this ratchet (40); One first pawl (60) and one second pawl (80); And control piece (100).
Body (10) has an operating portion (14), and this operating portion (14) comprises a groove (16), and it is reached by a diapire (18) and is formed around perisporium (20) within the diapire (18).Groove (16) is held before and can be held this ratchet (40), this first pawl (60) and this second pawl (80) in it.Be provided with a first wall (22) and one second wall (24) in the groove (16), this first pawl (60) and second pawl (80) are arranged at respectively between this first wall (22) and this second wall (24) and the ratchet (40), the configuration of this first wall (22) makes when this first pawl (60) is positioned at its primary importance, first pawl (60) clip between first wall (22) and ratchet (40) and with ratchet (40) engagement, so that this transfer of torque to be provided; The configuration of this second wall (24) makes when this second pawl (80) is positioned at its primary importance, and second pawl (80) clip is between second wall (24) and ratchet (40) and mesh with ratchet (40), so that transfer of torque to be provided.
One platform is located at the end of groove (16).This platform is from the outstanding height of diapire (18).Control piece (100) can be fixed on this platform.One of this platform end is defined by first wall (22) and second wall (24).Platform is provided with hole (H1), for control piece (100) can the pivot mode fixing.
According to a preferred embodiment, this first wall (22) extends towards one of close this second wall (24) second end near one of internal perisporium (20) first end from one.This first wall (22) has a gradient, makes that the distance between this second end and ratchet (40) is narrower than the distance between this first end and ratchet (40).This second wall (24) extends towards one of close this first wall (22) second end near one of internal perisporium (20) first end from one, this second wall (24) has a gradient, makes that the distance between this second end and ratchet (40) is narrower than the distance between this first end and ratchet (40).
According to another preferred embodiment, groove (16) comprises two accommodation chambers, holds this first pawl (60) and this second pawl (80) respectively in it; Wherein an accommodation chamber comprises this first wall (22), and another accommodation chamber comprises this second wall (24).First wall (22) and second wall (24) form the upward slope inclined-plane towards the inboard, that is tilt towards groove (16) front end.First pawl (60) is disposed between the first wall (22) of this body (10) and this ratchet (40) and can be with respect to this ratchet and mobile between a primary importance and a second place.At this primary importance place, this first pawl (60) is coupled with this ratchet (40) and is subjected to first wall (22) support, so that this body (10) provides transfer of torque via this first pawl (60) in one first direction of rotation.At this second place place, this first pawl (60) separates with this ratchet (40), not transfer of torque.
First pawl (60) comprises a side that is positioned between ratchet (40) and the first wall (22), is subjected to spring (S) bias voltage, makes this first pawl (60) and second pawl (80) normality ground and ratchet (40) coupling.According to an embodiment, one of spring (S) end is connected to a retaining piece (68,88) that firmly is resisted against internal perisporium.(refer under the situation of not controlled product (100) control) under normal conditions, first pawl (60) be subjected to spring (S) the application of force and along the direction that is roughly parallel to first wall (22) towards the tooth portion (42) of ratchet (40) near.
Second pawl (80) is disposed between second wall (24) of this body (10) and this ratchet (40) and can be with respect to this ratchet and mobile between a primary importance and a second place.At this primary importance place, this second pawl (80) is coupled with this ratchet (40) and supported so that this body (10) provides transfer of torque via this second pawl (80) in one second direction of rotation by second wall (24).At this second place place, this second pawl (80) separates with this ratchet (40), not transfer of torque.
Second pawl (80) comprises a side that is positioned between ratchet (40) and second wall (24), is subjected to spring (S) bias voltage, makes this first pawl (60) and second pawl (80) normality ground and ratchet (40) coupling.According to an embodiment, one of spring (S) end is connected to a retaining piece (68,88) that firmly is resisted against internal perisporium.The application of force of spring (S) is roughly parallel to first wall (22) and second wall (24).(refer under the situation of not controlled product (100) control) under normal conditions, second pawl (80) be subjected to spring (S) the application of force and along the direction that is roughly parallel to second wall (24) towards the tooth portion (42) of ratchet (40) near.Therefore, first pawl (60) and second pawl (80) are under the bias voltage of spring (S), and more to the inside, the interlock of tooth is tighter.Keep being spaced apart between this first pawl (60) and second pawl (80), so both movements can not interfere with each other.
The end tooth (66,86) of the tooth (62,82) of first pawl (60) and second pawl (80) is outstanding from its side (64,84) respectively, helps first pawl (60) and second pawl (80) when torque is provided, towards first wall (22) and second wall (24) application of force.
Control piece (100) can with an external reversing switch (120) coupling, and it is fixing to pass the bolt (101) at control piece (100) center with one.Control piece (100) can park through operation (for example via stirring a reversing switch (120) of being located at groove (16) outside) in primary importance, a second place and neutral position at least one of them.Shown in Fig. 6 A to Fig. 6 D, the back side of control piece (100) has first group of hole (104), second group of hole (106), the 3rd group of hole (108), can mesh steel ball (B) with being subjected to one of spring (S) bias voltage respectively.When this control piece (100) is positioned at this primary importance, be (control piece (100) right-hand rotation) shown in Fig. 6 B, first group of hole this moment (104) and steel ball (B) engagement, this first pawl (60) is coupled with this control piece (100), the side (64) of promotion first pawl (60), and controlled product (100) drives the primary importance away from first pawl (60), therefore the side (84) that allow to have only second pawl (80) and this ratchet (40) coupling, promotes second pawl (80) is so that this body (10) provides transfer of torque in this second direction of rotation.When this control piece (100) is positioned at this second place, be (control piece (100) left-hand rotation) shown in Fig. 6 C, the 3rd group of hole this moment (108) and steel ball (B) engagement, this second pawl (80) and this control piece (100) coupling, and controlled product (100) drives the primary importance away from second pawl (80), therefore allow to have only first pawl (60) and this ratchet (40) coupling, so that this body (10) provides transfer of torque in this first direction of rotation.When this control piece (100) is positioned at this neutral position, be (control piece (100) is positioned at middle) shown in Fig. 6 A, second group of hole this moment (106) and steel ball (B) engagement, this control piece (100) is not coupled with first pawl (60) and second pawl (80), and allow this body (10) that transfer of torque is provided in this first direction of rotation and this second direction of rotation simultaneously, so lock-out state in the middle of presenting.One of this case preferred embodiment is, this control piece (100) from first group of hole (104) to second group of hole (106) or from second group of hole (106) to the 3rd group of hole (108), preferable 20 degree that are spaced apart.
When assembling, one fixture (44) is used for making ratchet (40) to be pivotally fixed in operating portion, after each assembly was packed groove (16) into, cover plate (F), C shape ring (C) and ring (R) were fixed in control piece (100) with reversing switch (120) again with the open end sealing of groove (16).Certainly, reversing switch (120) is that operability is connected with control piece (100), so this case is not limited to control piece (100) is designed to same assembly or different assembly with reversing switch (120).
