Abstract
A stroke amplification device used for locks comprises a first level shifting block with handle loading holes, shifting fork and second level shifting block in the center, with the said first level shifting block having a fan gear and a return handle at the top end and bottom end respectively, a rack, having an opening at a side, matching with the fan gear equipped on the shifting fork, and a rod being shifted loaded in the middle of the second level shifting block within the rack opening, with power output post and locating shaft hole equipped respectively at the top and bottom ends of the second level shifting block. The said fan gear meshes the rack. The movement of the first level shifting block drives the horizontal movement of the shifting fork, whose opening in turn drives the horizontal movement of the inside rod being shifted. When the locating shaft is fixed, and the rod being shifted moves, the power output post also moves horizontally and the power output post has far bigger strokes than that of the rod being shifted.
Description
Technical field
The present invention relates to a kind of stroke amplification device, particularly a kind of stroke amplification device that is used for world lock.
Background technology
World lock is a kind of lockset that can lock door upper and lower brake(-holder) block when closing locking, and its operating principle is as follows: when opening the door, use key operated lock core, side's tongue withdrawal, press down 45 ° on handle, bump tongue and power rail and regain and drive upper and lower brake(-holder) block withdrawal simultaneously, it is restorable that door is opened handle; When locking a door, 45 ° of last handles bump tongue and stretch out, and power rail drives upper and lower brake(-holder) block and stretches out, and lock lock core with key or at in-house operation hand button, and square tongue also stretches out locking, and the locked while handle of door can return.Door is subjected to up and down brake(-holder) block, square tongue when locked simultaneously and bumps tongue restriction everywhere, and safety improves many.Also there is weak point in this lock: brake(-holder) block is driven by power rail up and down, power rail is promoted by handle again, and the stroke of brake(-holder) block is greater than the power stroke of power rail up and down, and its stroke deficiency need be provided with spring and remedy, thereby the stroke of handle can not satisfy the stroke of brake(-holder) block up and down completely.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of amplifying device that can amplify the handle stroke.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stroke amplification device that is used for world lock, comprise that the center is provided with the one-level shifting block of handle installing hole, also comprise shift fork and secondary shifting block, described one-level shifting block upper and lower side is respectively arranged with sector gear and coordination handle, shift fork is provided with the tooth bar that is complementary with sector gear, tooth bar one side is provided with prong, secondary shifting block middle part is provided with and is subjected to reversed column, upper and lower side is respectively arranged with power output post and positioning shaft hole, described sector wheel and rack engagement is placed in the prong by reversed column.
Wherein, be subjected to reversed column between power output post and positioning shaft hole.
The invention has the beneficial effects as follows: the engagement of sector wheel and rack, be placed in the prong by reversed column, during handle in being rotatably installed in the handle installing hole, the one-level shifting block rotates, drive the shift fork horizontal movement, prong on the shift fork drives the built-in reversed column that is subjected to again and moves horizontally, under the situation that positioning shaft hole is fixed, when moved horizontally by reversed column, power output post also moves horizontally, and the stroke of power output post will be far longer than the stroke that is subjected to reversed column, such as, power output post to the distance that is subjected to reversed column equal to be subjected to reversed column arrive positioning shaft hole apart from the time, the stroke that power is exported post is the twice that is subjected to the reversed column stroke.

The specific embodiment
Referring to figs. 1 through Fig. 4, a kind of stroke amplification device that is used for world lock, comprise that the center is provided with the one-level shifting block 7 of handle installing hole 72, shift fork 8 and secondary shifting block 9, the upper and lower side of one-level shifting block 7 is respectively arranged with sector gear 71 and return handle 73, shift fork 8 is provided with the tooth bar 81 that is complementary with sector gear 71, tooth bar 81 1 sides are provided with prong 82, secondary shifting block 9 middle parts are provided with and are subjected to reversed column 92, upper and lower side is respectively arranged with power output post 91 and positioning shaft hole 93, described sector gear 71 and tooth bar 81 engagements are placed in the prong 82 by reversed column 92.During handle in being rotatably installed in handle installing hole 72, one-level shifting block 7 rotates, drive shift fork 8 horizontal movements, prong 82 on the shift fork 8 drives the built-in reversed column 92 that is subjected to again and moves horizontally, under the situation that positioning shaft hole 93 is fixed, when moved horizontally by reversed column 92, power output post 91 also moves horizontally, and its stroke will be far longer than the stroke that is subjected to reversed column 92.
As a kind of embodiment of the present invention, be arranged between power output post 91 and the positioning shaft hole 93 by reversed column 92, be positioned on the straight line through power output post 91 and positioning shaft hole 93, also be provided with the hole of bead 94, location on the secondary shifting block 9, the hole of bead, location 94 built-in positioning beads 13.Power output post 91 on the secondary shifting block 9 to the distance that is subjected to reversed column 92 equal to be subjected to reversed column 92 arrive positioning shaft hole 93 apart from the time, the stroke of power output post 91 is the twice that is subjected to reversed column 92 strokes, when the trip amplifying device was used for world lock, brake(-holder) block also can amplify many times about the stroke of handle can be passed to completely.
With reference to Fig. 5, when opening the door, earlier with the lock core on the key operated lock body 1, tongue 4 withdrawals of side's tongue, operating grip, handle drives 7 rotations of one-level shifting block, drives shift fork 8 horizontal movements, and the prong 82 on the shift fork 8 drives the built-in reversed column 92 that is subjected to again and moves horizontally, because positioning shaft hole 93 is fixed on the lock body 1, when moved horizontally by reversed column 92, power output post 91 also moves horizontally, and drives power rail 10 simultaneously and moves horizontally, last brake(-holder) block 5 and following brake(-holder) block 6 that power rail 10 drives its two ends again move, on, following brake(-holder) block is regained the back door and is opened, and return button 11 resets under the effect of spring 12, and 7 revolutions of one-level shifting block also drive the handle return.
When locking a door, operating grip, handle drives 7 rotations of one-level shifting block, its stroke is delivered to power rail 10 and is exaggerated, power rail 10 drives upward, and brake(-holder) block 5 stretches out with following brake(-holder) block 6, simultaneously one-level shifting block 7 drives and bumps the tongue shifting block and retract and bump tongue, lock lock core with key or at in-house operation hand button again, square tongue stretches out, and the locking column on the square tongue is locked in the groove of power rail 10, power rail is by locking, door is locked, and simultaneously handle can return, bumps tongue once more in the access door panel, door is subjected to brake(-holder) block up and down simultaneously when locked, side's tongue and bump tongue restriction everywhere, safety improves many.
The above-mentioned just preferred embodiment of the present invention, but should not be construed as limiting the invention, so long as adopt the technical scheme that is equal to the present invention, also should be within the protection domain of the invention.
