Description
Technical field
The utility model relates to a kind of hand switch door of electromagnetic shield door, belongs to the electromangnetic spectrum field, also can be used on the translation shield door.
Background technology
At present, electromagnetic shield door crack between a door and its frame shield member is traditional knife block and secondary composition of spring finger groove, because frictional resistance was too large when cutter inserted the spring finger groove, hardly may switch gate by instrument if artificial, driving mechanism under the prior art has electronic and manual pattern, electronic pattern is laborsaving, but complex structure, fault rate are higher; The conventional manual switch gate is that tiller drives 2 interlocks (in a side of door) pattern, because handle is long limited, the opposite side (side that hinges) at back door of opening the door still has the part knife block to stay in the spring finger groove, mechanical efficiency is low, the strength of bat-handle switch door is still bigger than normal, and namely manual control switch's shield door labour intensity is large.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provides that a kind of compact conformation, reliability are high, mechanical efficiency is high, reduces the hand switch door of the electromagnetic shield door of manual control switch's shield door labour intensity.
The technical scheme that realizes the utility model purpose is: a kind of hand switch door of electromagnetic shield door, comprise and be with backed door leaf skeleton, also comprise gear shaft and two transmission locking devices, the handwheel whirligig is installed on the door leaf skeleton, be set with driven wheel on the handwheel whirligig, the top of gear shaft is fixed with the first driven gear that is meshed with driven wheel, be set with the second driven gear on the gear shaft, the transmission locking device comprises axis of rotation, push rod, tooth bar, the lockwheel part that is separately fixed at the crank slot wheel of rotating shaft terminal and is fixed on the fork on the axis of rotation and matches with the crank slot wheel, axis of rotation can be rotated to support on the bearing, one end and the fork of push rod are hinged, the other end of push rod is connected with tooth bar, and two tooth bars are meshed with the second travelling gear respectively.
Further, be fixedly connected with gear housing on the described door leaf skeleton, have rach slot on the gear housing, two toothed rack are slidably mounted in the rach slot by the bearing that is arranged on the tooth bar both sides respectively.
Further, be fixedly connected with keeper on the described gear housing, described the second driven gear can be rotated to support on the keeper.
Further, be fixedly connected with to limit the limited block of rack stroke on the described gear housing.
After having adopted technique scheme, the artificial handwheel whirligig that rotates, driven wheel just and then rotates, the first driven gear rotates, and gear shaft and then rotates, thereby the second driven gear rotates, driving two toothed rack moves, the rack drives push rod moves, and fork swings, and axis of rotation just and then rotates, the crank slot wheel just follows suit and rotatablely moves, with the lockwheel part on the crank slot incision doorframe of four crank slots wheel, door leaf close the door action, manually counter-rotation handwheel whirligig, then realize opening the door action, the utility model compact conformation, reliability is high, and mechanical efficiency is high, can reduce the labour intensity of manual control switch's shield door; The bearing that the tooth bar both sides arrange replaces sliding-contact with the rolling contact of bearing, has reduced frictional force, boosts more laborsaving, has further reduced hand labor intensity.
Description of drawings
Fig. 1 is the structural representation of the hand switch door of electromagnetic shield door of the present utility model;
Fig. 2 is the partial sectional view of the hand switch door of electromagnetic shield door of the present utility model.
The specific embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
Such as Fig. 1, shown in 2, a kind of hand switch door of electromagnetic shield door, comprise the door leaf skeleton 1 with bearing 1-1, also comprise gear shaft 2 and two transmission locking devices, handwheel whirligig 4 is installed on the door leaf skeleton 1, be set with driven wheel 5 on the handwheel whirligig 4, the top of gear shaft 2 is fixed with the first driven gear 6 that is meshed with driven wheel 5, be set with the second driven gear 7 on the gear shaft 2, the transmission locking device comprises axis of rotation 3, push rod 8, tooth bar 9, be separately fixed at the crank slot wheel 16 at axis of rotation 3 two ends and be fixed on the axis of rotation 3 fork 10 and with the crank slot wheel 16 lockwheel parts 11 that match, axis of rotation 3 can be rotated to support on the bearing 1-1, one end and the fork 10 of push rod 8 are hinged, the other end of push rod 8 is connected with tooth bar 9, and two tooth bars 9 are meshed with the second travelling gear 7 respectively.
As shown in Figure 2, be fixedly connected with gear housing 12 on the door leaf skeleton 1, have rach slot 12-1 on the gear housing 12, two toothed rack 9 are slidably mounted in the rach slot 12-1 by the bearing 13 that is arranged on tooth bar 9 both sides respectively.Be fixedly connected with keeper 14 on the gear housing 12, described the second driven gear 7 can be rotated to support on the keeper 14.
