Abstract
The invention discloses a kind of single-point locking type shielding lock locking structure and compact electromagnetic shield door, it is spiral lift locking mechanism by the wedge lock structural change of script, slided by locking body in the guide-track groove of spiral lift locking mechanism to realize that opening and closing, its switch gate resistance of the shield door under the cases of emergency such as power failure are small and simple in structure.
Description
Technical field
The present invention relates to a kind of single-point locking type shielding lock locking structure and compact electromagnetic shield door, belongs to shielding gate technique neck
Domain, more particularly to the locking technology of shield door.
Background technology
Large-scale screened room is in the case where shield door closes completely, if there is fault and special circumstances, indoor room
Outer to completely cut off information, outdoor personnel hardly result in the distress signals of office work personnel, need at this time a kind of small-sized and convenient light
Unclamp the manual-operated emergent escape shield door opened.
Existing manual shield door is to use inclined wedge locking mode mostly, i.e., drives door leaf by rack and pinion drive mechanism
On lock pin engaged with the angled-lift splits on doorframe with departing to realize the switch of shield door.Its switch gate power is with hinge length and tiltedly
The angle of inclination of sliding block wedge structure is related.And the shield door that emergency escape uses, overcome the enabling resistance of reed should be smaller
Better, reducing resistance method mainly has two kinds：
One：The distance between shield door hinge axis of rotation and the door leaf edge of a knife are lengthened, allows the door leaf edge of a knife to cut doorframe spring with this
The angle of film trap keeps vertical as far as possible, so as to reduce enabling resistance.This method will certainly increase the length of hinge, so as to increase screen
The size of the width of door is covered, for small-sized emergency escape shield door and is not applied to.
Two：Reduce the angle of inclination of angled-lift splits wedge structure, the power that opens Door by Hand is amplified with this, so as to reduce enabling resistance
Power.This method will keep the same incision stroke of the edge of a knife, reduce angle of inclination, certainly will increase the length dimension of angled-lift splits.
Although reducing enabling resistance, the angled-lift splits increased shows more too fat to move by the locking mechanism of shield door, brings at the same time
The increase of processing cost and the deficiency of overall aesthetics.
The content of the invention
The technical problems to be solved by the invention are：Overcome the deficiencies of the prior art and provide a kind of single-point locking type shielding
Locking mechanism and compact electromagnetic shield door, its switch gate resistance are small and simple in structure.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of single-point locking type shielding lock locking structure, bag
Include the locking body on shielding door frame and the spiral lift locking mechanism in shield door door body, the spiral liter
The guide-track groove of screw type is provided with journey locking mechanism, the guide-track groove has opening portion, and the locking body is slided from the opening portion
Into or skid off the guide-track groove, and can be slided along the guide-track groove of the screw type, to complete the switch of shield door.
Further, the locking body being installed on shielding door frame is locking bearing.
Further, the spiral lift locking mechanism includes spiral locking wheel and drives the handle machine of spiral locking wheel rotation
Structure, the guide-track groove are the helix-type flute around the surface for being arranged on spiral locking wheel surface, and the guide-track groove with it is described
Lock mates.
Further, the handle mechanism includes Handle axis, and the Handle axis is coaxially disposed with spiral locking wheel, and handle
Axis is fixedly connected with spiral locking wheel by flat key.
Further, one end of the Handle axis is equipped with external screw thread, should have externally threaded end to stretch out the spiral locking
Wheel, and be installed on by a taper roll bearing in shield door door body, it is additionally provided with the taper roll bearing and the hand
The matched locking nut of external screw thread of arbor end, when Handle axis drives spiral locking wheel rotation, Handle axis has outer spiral shell
The end of line is rotated relative to locking nut.
Further, the opening portion is arranged on one end of the remote door body of guide-track groove, when Handle axis drives spiral locking wheel
When rotation is to lock shield door door body, while Handle axis rotation, screwed out with respect to locking nut；When Handle axis drives spiral locking
When taking turns rotation and being locked so that shield door door body is released, while Handle axis rotation, opposite locking nut screw-in.
Further, the taper roll bearing is provided outside step, and step passes through step base and door
Body is fixedly connected.
Further, the end of the other end of the Handle axis is fixedly connected with a rotation handle.
Further, the other end of the Handle axis is provided with thrust ball bearing, and the thrust ball bearing is provided outside axis
Bearing, the top chock are fixedly connected by top chock base with spiral locking wheel.
The present invention also have submitted a kind of compact electromagnetic shield door, including the single-point locking type shielding lock locking structure.
After employing above-mentioned technical proposal, the invention has the advantages that：
The wedge lock structural change of script is spiral lift locking mechanism by the present invention, by locking body in spiral lift
The opening and closing to realize shield door under the cases of emergency such as power failure are slided in the guide-track groove of locking mechanism；The locking of the present invention
The resistance that body opposite rail groove slides can reduce the resistance by extending the flight of guide-track groove, extend the spiral shell of guide-track groove
Rotating journey, to increase the rotating distance of Handle axis, so as to reduce enabling resistance, more convenient the emergent of office work personnel is escaped
It is raw, without increasing the length of hinge, make escape shield door overall structure compacter, it is beautiful.
