Embodiment 1

[0033] A passive total locking device based on directional control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with an end toothed plate, a shaft designed integrally with the drive shaft 7 To the cam 4, a follower 5, a ring spring 6, an end tooth plate 8, a cylindrical spring 9, a housing 10, a torsion spring 11. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the axial cam 4 in a rotational idle motion. The fixed side (the outer casing) of the one-way clutch 2 is fixedly connected with the sleeve 3, and the toothed disc of the sleeve 3 is connected to the end toothed disc. 8 Paired clutches, the pins 12 on the axial cam 4 are inserted into the openings of the cage 51 of the follower 5 to realize the two rotating idle motion nesting, a group of rollers 52 roll on the corresponding step ramp of the axial cam 4, and the annular The spring 6 is installed in the groove of the retainer 51, and the...

Embodiment 2

[0037] A passive total locking device based on directional control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with an end toothed plate, an axial cam 4, a driven 5, a ring spring 6, a drive shaft 7, an end tooth plate 8, a cylindrical spring 9, a housing 10, a torsion spring 11. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the driving shaft 7 in a free-running rotation. The fixed side (the outer casing) of the one-way clutch 2 is fixedly connected with the sleeve 3, and the toothed plate of the sleeve 3 is matched with the end toothed plate 8 Clutch, the axial cam 4 is idly sleeved on the drive shaft 7, and the pin 12 is inserted into the opening of the cage 51 to realize the two rotation idling nesting, and a set of rollers 52 roll on the corresponding step ramp of the axial cam 4, The retainer 51 of the follower 5 is fixedly connected with the end gear plate 8, the ring spring 6 is inst...

Embodiment 3

[0040] A passive full-length locking device based on directional control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with a cylindrical gear plate, a radial cam 4, a driven 5 , a ring spring 6 , a drive shaft 7 , a cylindrical spring 9 , a housing 10 , a torsion spring 11 , a stop pin 13 . The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the drive shaft 7 in a free-running rotation. The fixed side (the outer casing) of the one-way clutch 2 is fixedly connected with the sleeve 3, and the cylindrical gear plate of the sleeve 3 is connected with the driven part 5. The wedge-shaped portion 51 of the cam is matched for clutching, the radial cam 4 is vacantly sleeved on the drive shaft 7, and the stop pin 13 fixedly connected with the housing 10 is inserted into the notch of the radial cam 4 to limit the rotation angle of the radial cam 4, from The roller 52 of the follower 5 rolls on the correspond...

Abstract

The invention discloses a passive full-range locking device based on direction control, which includes an inner sleeve connected with a door transmission part, a one-way clutch allowing the inner sleeve to rotate freely in the door closing direction, and a belt fixedly connected with the one-way clutch shell. A sleeve with meshing teeth, a drive member with a rated rotational space with the inner sleeve, a stopper that can be disengaged from the sleeve, and one or a set of elastic forces that act on the stopper to make it tend to engage with the sleeve Parts, a rotating support sleeve, driving parts and other housings that must be installed, also include a cam, a follower that cooperates with the cam to form a cam mechanism, and one or a group of torque generators; the cam and the follower There is a rated rotation space between the moving parts. The invention completely solves the principle defect of the existing device, and the overall structure has the characteristics of compactness and conciseness.

Description

technical field [0001] The invention relates to the technical field of door leaf locking devices, in particular to a passive full-range locking device based on direction control. Background technique [0002] The full-length locking device is an important type of door system locking device in the traffic field. With its full-length one-way locking feature, the door obtains some special functions and performances. According to whether the whole process locking device has independent control power components, it can be divided into "active whole process locking device" and "passive whole process locking device". The "active full locking device" has a complex structure, large volume, high cost, heavy weight and high energy consumption, while the "passive full locking device" has a compact structure, low cost, light weight and no energy consumption. [0003] Patent application 96101108.4 discloses a drive device, which is different from ordinary one-way devices in that it has a...
