Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
As shown in Figure 1, being scheme of installation of the pneumatic locking mechanism 1 of stopping sliding door in stopping sliding door.
As shown in Fig. 2, being 1 structural schematic diagram of pneumatic locking mechanism of stopping sliding door.A kind of pneumatic locking mechanism of stopping sliding door
1, including single-acting cylinder and clutch.Single-acting cylinder includes cylinder block 11, piston assembly 12, gas-tpe fitting 13, friction
Piece 14, guiding axis 15, return spring 16 and retaining ring 17.Cylinder block 11 is mounted on right support 2, is connect on cylinder block 11 equipped with tracheae
First 13, for outputting and inputting for air-flow, piston assembly 12 is mounted in cylinder block 11, is equipped with and is rubbed in the end face of piston assembly 12
Pad 14, for the engagement of 23 end face of Moving plate or separate, multiple guiding are equably housed in 12 circumferential end surfaces of piston assembly
Axis 15, guiding axis 15 are each passed through the pilot hole in piston assembly 12 and cylinder block 11, make piston assembly 12 along 15 axis of guiding axis
To movement, retaining ring 17 is housed in the other end of guiding axis 15,17 sets of return spring on guiding axis 15, one end is pressed in cylinder block 11
End face, one end are pressed on retaining ring 17.Guiding axis 15 both can be such that piston assembly 12 moves axially so, while prevent piston assembly
12 rotary motion in cylinder block 11.
Clutch is made of clutch fixing seat 21, bearing 22, Moving plate 23, shaft joint 24, key 25.Clutch is solid
Reservation 21 is fixedly connected with cylinder block 11, and bearing 22 is mounted in clutch fixing seat 21, and Moving plate 23 is mounted in 22 inner ring of bearing
On, and it is fixed by the right screw 3 of shaft joint 24 and key 25 and stopping sliding door.
When air flows to cylinder by gas-tpe fitting 13, piston assembly 12 moves along guiding axis 15 under the influence of air pressure, makes
The friction plate 14 for being mounted on 12 front end of piston assembly is tightly bonded with Moving plate 23, prevents the rotation of left screw 31, right screw 3
Movement, so that left-hand door fan 8, right door leaf 7 be made to be locked up.
When the air in cylinder is connected by gas-tpe fitting 13 and atmosphere, return spring 16 pulls piston assembly 12 and band
Movable friction plate 14 is separated with Moving plate 23, and driving motor can pass through left screw 31, right screw 3, Left Drive nut 10, right transmission nut
5, door frame 9 is taken on a left side, door frame 6 is taken on the right side moves left-hand door fan 8, right door leaf 7.It can also be drawn under emergency conditions with opening and closing plug manually at this time
Door.
The working principle of the invention is: when at closing time: driving motor work, while being deflated by solenoid valve 4 to cylinder, it drives
The dynamic rotation of motor 33 drives left screw 31, right screw 3 to rotate, by Left Drive nut 10, right transmission nut 5, a left side take door frame 9,
It takes door frame 6 and left-hand door fan 8, right door leaf 7 is driven to move in the right side.When door leaf is closed in place, driving motor 33 is powered off, while passing through solenoid valve
4, gas-tpe fitting 13 moves under certain air pressure to cylinder charge, piston assembly 12, and friction plate 14 is pushed to press to Moving plate 23, so that
Screw rod stop motion, have final drive take door frame and door leaf is locked up, system is maintained at shutdown state.
When opening the door: being deflated by gas-tpe fitting 13, solenoid valve 4 to cylinder, while driving motor 33 being made to work, driven left
Screw rod 31, right screw 3 and stopping sliding door door leaf are moved to enabling direction, and until opening the door, rear drive mechanism in place is powered off.
Under emergency conditions: should be at shutdown situation at this time, single-acting cylinder is deflated, and keeps piston total by return spring 16
Moving plate 23 is left at 12 and friction plate 14.Door leaf is moved with hand push, can more easily open stopping sliding door.
Although the present invention has been described by way of example and in terms of the preferred embodiments, embodiment is not for the purpose of limiting the invention.Not
It is detached from the spirit and scope of the present invention, any equivalent change or retouch done also belongs to the protection scope of the present invention.Cause
