Embodiment 1

[0033] A passive full-range locking device based on direction control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with an end sprocket, and a shaft designed integrally with the drive shaft 7 To the cam 4, a follower 5, an annular spring 6, an end sprocket 8, a cylindrical spring 9, a housing 10, and 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 the idle motion. The fixed side (outer shell) of the one-way clutch 2 is fixedly connected with the sleeve 3. The toothed plate of the sleeve 3 and the end toothed plate 8 paired clutch, the pin 12 on the axial cam 4 is inserted into the opening of the cage 51 of the follower 5 to realize the nesting of the two rotating idle distances, a group of rollers 52 roll on the corresponding step ramp of the axial cam 4, and the circular The spring 6 is installed in the groove of the cage 51, and the elastic force of th...

Embodiment 2

[0037] A passive full-range locking device based on direction control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with end toothed discs, an axial cam 4, and a driven Part 5, a ring spring 6, a drive shaft 7, an end sprocket 8, a cylindrical spring 9, a housing 10, and a torsion spring 11. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the drive shaft 7 in idle motion. The fixed side (outer shell) of the one-way clutch 2 is fixedly connected with the sleeve 3, and the toothed plate of the sleeve 3 is paired with the end toothed plate 8. Clutch, the axial cam 4 is vacantly sleeved on the drive shaft 7, and a pin 12 is inserted into the opening of the cage 51 to realize the nesting of the two rotating idle distances, and a set of rollers 52 roll on the corresponding step ramp of the axial cam 4, The cage 51 of the follower 5 is fixedly connected with the end sprocket 8, and the ring spring 6 i...

Embodiment 3

[0040] A passive full-range locking device based on direction control, including an inner sleeve 1 connected with the door transmission part, a one-way clutch 2, a sleeve 3 with a cylindrical toothed disc, a radial cam 4, and a driven Part 5, a ring spring 6, a drive shaft 7, a cylindrical spring 9, a housing 10, a torsion spring 11, and a stop pin 13. The inner sleeve 1 is installed in the one-way clutch 2 and is nested with the driving shaft 7 in idle motion. The fixed side (outer shell) of the one-way clutch 2 is fixedly connected with the sleeve 3, and the cylindrical toothed plate of the sleeve 3 is connected with the follower 5 The wedge-shaped part 51 of the radial cam 4 is paired and clutched, the radial cam 4 is sleeved on the drive shaft 7, and the stop pin 13 fixedly connected with the housing 10 is inserted into the gap of the radial cam 4 to limit the rotation angle of the radial cam 4, from The roller 52 of the moving part 5 rolls on the corresponding step ramp o...

Abstract

The invention discloses a passive whole-course locking device based on direction control. The passive whole-course locking device comprises an inner sleeve connected with a door transmission part, a one-way clutch allowing the inner sleeve to freely rotate in the door closing direction, a sleeve fixedly connected with a shell of the one-way clutch and provided with meshing teeth, a driving part provided with a rated rotating idle stroke with the inner sleeve, a retainer which can be separated from and combined with the sleeve, one or a group of elastic pieces which act on the retainer to enable the retainer to tend to be meshed with the sleeve, a rotary supporting sleeve, a driving piece and other necessary shells, and further comprises a cam, a driven piece which is matched with the cam to form a cam mechanism, and one or a group of torque generating pieces; and a rated rotating idle stroke is arranged between the cam and the driven piece. The passive whole-course locking device thoroughly overcomes principle defects of an existing device, and the overall structure has the advantages of being compact and simple.

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-range locking device is an important type of door system lock device in the transportation field. Its full-range one-way locking feature enables the door to obtain some special functions and performances. According to whether the full-range locking device has independent control power components, it can be divided into "active full-range locking device" and "passive full-range locking device". The "active full locking device" has a complex structure, large volume, high cost, bulkiness 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 driving device, which is different from ordinary one-way devices in that it has a var...
