Description
Technical field
The utility model relates to a kind of fan every access control system middle fan gate-type opening and closing mechanism.
Background technology
The fan door mechanism that uses in the present gate system adopts the electromagnetic brake device on the motor to lock the fan door closure state; When fan Men Zaiguan closed procedure was subjected to external drag effect, motor acted on the moment of cutting out of fanning door by mechanism, corresponding reducing under interlock circuit control.
Summary of the invention
In order to simplify the circuit kit controlling organization, the invention provides a kind of slide block type and fan door mechanism; The fan door-hinge is by the fan door pivot, be installed on the installing plate, the fan door pivot is by the slide block assembly driven rotary, reach and open the door and close the door, slide block assembly is driven by power twister and rotates, and power twister is by Motor Drive, and the extreme position of fan door opening and closing is by chute decision in the middle of the rocker in the slide block assembly, the motor outage is set by the limit position sensor of fan door opening and closing;
Slide block assembly comprises a slide block, a rocker, a force transmitting board and a driving lever, chute is arranged in the middle of the rocker, be connected by bearing pin between driving lever and the slide block, constitute hinges, be free to slide in the chute of slide block in the middle of the rocker, constitute the planar slide pair, rocker is connected by key pin and screw with fanning between the door pivot, driving lever is connected with force transmitting board, and force transmitting board is connected with power twister;
Power twister is to clamp motor rotary shaft by a spring clip, the openend of clip is screwed by a screw, is with spring on the screw, the other end of clip is fixed on force transmitting board on the spring clip with screw, the other end of force transmitting board is screwed on driving lever, and motor rotates, and drives spring clip and rotates, spring clip drives force transmitting board and rotates, force transmitting board drives driving lever and rotates, and driving lever drives slide block and slides in the rocker chute, and forces rocker to do to rotate in the certain angle scope;
Between slip and the bearing pin oscillating bearing being arranged, is two spacers between oscillating bearing and the bearing pin;
The rotational angle of fan door is according to rotating condition enactment, and the fan door is at the extreme position of opening or closing, and relative two centers of rotation in the center of slide block are promptly fanned the 90 ° of angles that are wired to of door-hinge and motor shaft.
Advantage of the present invention is, mechanism design is simple, starts and stop comparatively steady, and overload protection function is arranged, the fan door self-locking of limit position, and motor need not brake request, and is easy to manufacture, easy to maintenance; Because power twister is to hold tightly on motor shaft by spring structure, when outside add to spring clip moment greater than motor shaft and spring clip between during moment of friction, the relative spring clip of motor shaft skids, motor need not to pass through interlock circuit, the change of control machine shaft output torque is to meet the requirement of associated safety regulation; When fanning door at the extreme position of opening or closing, the bearing pin center respectively with two centers of rotation, promptly fan the 90 ° of angles that are wired between door-hinge and the motor shaft, this moment is if there is external force to act on the fan door, corresponding rocker is vertical and pass through electrical axis to the force direction of driving lever, be this active force to the torque of driving lever be zero, thereby realize the auto-lock function requirement of fan door mechanism; Thus, the motor of selecting for use need not subsidiary check mechanism.
Because the pivot angle scope of the chute length of rocker restriction rocker, corresponding driving lever also can only be swung in the scope of the complementary angle of rocker pivot angle; The unlatching of fan door or closing angle scope can need to decide because of condition.Slide block assembly in the utility model mechanism has automatic aligning, good guidance and auxiliary body's auto-lock function requirement.

Label declaration in the accompanying drawing:
1-sensor, 2-sensor, 3-installing plate, 4-are fanned door, the 5-motor, 6-screw, 7-screw, 8-spring clip, the 9-force transmitting board, the 10-driving lever, 11-fans door-hinge, 12-rocker, the 13-key pin, 14-slide block, 15-screw, the 16-support of bearing, the 17-motor shaft, 18-spring, 19-screw, 20-spacer, the 21-oscillating bearing, 22-spacer, 23-bearing pin.
The specific embodiment
See also accompanying drawing 1, open or the opposite fan door mechanism of closing direction for fan door 4, by fan door-hinge 11 center line minute surface symmetries, its driving member is a motor 5, spring clip 8, force transmitting board 9, driving lever 10, slide block 14, rocker 12, and fan door-hinge 11,4 and installing plates 3 of fan door during installing plate 3 design.
All fixtures all are installed on the installing plate 3 among the figure, motor shaft 17 protrude ends of motor 5 are supported by the support of bearing 16, hold motor shaft 17 tightly under the effect of spring clip 8 by screw 19 and spring 18, the bigger loose fit in crack between driving lever 10 and the motor shaft 17, be rigidly connected by structural members such as force transmitting board 9 and screw 6 and screws 7 between spring clip 8 and the driving lever 10, constitute hinges by bearing pin 23 between driving lever 10 and the slide block 14, constitute the planar slide pair between slide block 14 and rocker 12 chutes, be that slide block 14 is free to slide in the chute of rocker 12, be rigidly connected by key pin 13 and screw 15 between rocker 12 and the fan door-hinge 11, fan door 4 and fan door-hinge 11 are for being rigidly connected.
See also accompanying drawing 2, connect together by spring 18 and screw 19 between medi-spring clip 8 of the present invention and the motor shaft 17.Spring 18 is under the effect of screw 19, and the pressure of openend effect to spring clip 8 forces the inside shrinkage strain of spring clip 8 endoporus, thereby motor shaft 17 is held tightly.In the process that fan door 4 is opened or closed, fan door 4 is subjected under the external force effect, by each force transferring structure spare, spring clip 8 is produced a moment of torsion, if this moment of torsion and motor shaft 17 act on spring clip torque vector and greater than the maximum static friction moment between spring clip 8 and the motor shaft 17, then spring clip 8 skids mutually with motor shaft 17, and fan door 4 is forced to quicken to open or quicken close, so the present invention meets the requirement of associated safety regulation.When fan door 4 is opened or is closed to limit position, as shown in Figure 1, master control system sends instruction by sensor 1 or sensor 2 feedacks and makes motor 5 outages, if rotating, motor shaft 17 fails in time to stop, because slide block 14 is restricted by the chute of rocker 12, mechanism produces a stalling torque to spring clip 8, skids mutually between motor shaft 17 and the spring clip 8.
See also accompanying drawing 3, the slide block assembly of the utility model design has automatic aligning, good guidance and auxiliary rocker auto-lock function; Slide block 14 lateral layout are the plane along a diameter symmetry; as shown in Figure 1, good fit with the chute directed side of rocker 12, slide block 14 is free to slide in the chute of rocker 12; owing to be plane contact, but the auto-lock function requirement is fully satisfied in the assurance mechanism design.Select oscillating bearing 21 for use between slide block 14 and the bearing pin 23, for different installations and load, oscillating bearing 21 can automatic aligning, thereby makes slide block be subjected to force direction all the time in the plane vertical with motor shaft.It is free that spacer 20 and spacer 22 can guarantee fully that slide block 14 rotates relative to bearing pin.
