Abstract
A thin shutter lock is composed of a lock casing, a block, left and right pull rods, an outer lock container, and a gear, wherein the outer end of each pull rod via a rod lock is engaged with lock slots at two lower sides of gate, to unlock or lock the shutter, the inner end of each pull rod is arranged with a rack, a straight tooth slot near the outer side of the rack, and an inclined edge near the inner side of the rack, the gear is arranged with between the two racks to be meshed, the gear shaft is arranged with two straight teeth on symmetry positions, while one straight tooth is arranged with a pin, the gear is arranged with the block, with two symmetry grooves engaged with the pin on the gear. When the core of the outer lock container is inserted into the central square hole of the block to be rotated, the racks on the two pull rods are reversely driven by the pin and the gear, to unlock or lock shuttle lock. The utility model has easy, reliable, and force-saved switch, with long service life.
Description
Technical field
The utility model relates to coil brake lock class technical field, particularly a kind of slim coil brake lock.
Background technology
Existing a kind of coil brake lock is by lock housing 1, shifting block 2, pin 3, a left side, right pull bar 7,5, parts such as location-plate 4 and outer lock gall constitute, outer lock gall core inserts the core hole 5 that is located at shifting block 2 central authorities and drives shifting block 2 rotations, symmetrically arranged pin 3 enters respectively and is located at a left side on the shifting block 2, right pull bar 7,5 the 1st or the 2nd semicircle grooves near core hole one end, drive a left side, right pull bar 7,5 do counter motion simultaneously, a left side, right pull bar 7, a plurality of elliptical apertures that 5 outer ends are set, be connected with lever pin one end, this lever pin other end cooperates with both sides, rolling-gate bottom locked groove, realizes that coil brake lock closes state or opening.Figure 1 shows that the opening of this lock, Figure 2 shows that the locked state of this lock.Since from a kind of state to another kind of state procedure, shifting block 2 will rotate 360 ° of angles, being example from opening to the locked state process, at this moment, after clockwise rotating shifting block 2 certain angles, its two pins 3 enter the 1st groove 8 of right pull bar 5 respectively and the 2nd groove 11 of left pull bar 7 makes two poles 5,7 outwards motions, middle through behind one section room, two pins 3 enter the 2nd groove 9 of right pull bar 5 and the 1st groove 10 of left pull bar 7 again respectively, drive a left side, right pull bar 7, the 5 outer final positions that extend, gate is in locked state, and at this moment, two pins 3 have rotated 360 ° of angles and have been positioned at two bars 5, between 7 on the center line in room.Opening process in contrast.Because coil brake lock is mounted in it on a slice brake lining, brake lining is elongated zinc-plated stalloy, gate often all can be subjected to influenced by wind pressure and become an arc shape, and lever pin is a rigid member, thereby lever pin can produce a bounce, does not enter when pin 3 before the semicircle groove of opposite pull bar, this bounce can make left and right pull bar 7,5 displacements, thereby it is two pins 3 can not be entered in the predetermined semicircle groove, cause this lock moving process to have some setbacks, even stuck.
Summary of the invention
The technical problems to be solved in the utility model is that the folding of lock is smooth and easy, reliable, laborsaving, durable.
The technical solution that the utility model proposed is such: a kind of slim coil brake lock, comprise lock housing, shifting block 8, left side pull bar 10 and right pull bar 15 and outer lock gall, a left side, right pull bar 10,15 outer ends cooperate with both sides, gate bottom locked groove by lever pin, a described left side, right pull bar 10,15 the inners are provided with one section tooth bar 12, be provided with a straight-tooth groove 14 near these tooth bar 12 outsides, be provided with a hypotenuse 11 near these tooth bar 12 inboards, between described two tooth bars 12, be provided with a gear that is engaged with 13, on these gear 13 axisymmetric positions, be respectively equipped with a straight-tooth 16, and a straight-tooth 16 is provided with a pin 17 therein; One shifting block 18 is housed above the described gear 13, and this shifting block 18 is provided with the groove 19,20 of two symmetries, is connected with pin 17 on the gear 13.
The core hole that outer lock gall core inserts shifting block central authorities drives the shifting block rotation, and a groove drive pin on the shifting block makes gear follow rotation, drives left and right pull bar by the wheel and rack engagement and does counter motion simultaneously, realizes rolling up the sealed of lock or unlatching.The gear inhour is that coil brake lock closes state when rotating to straight-tooth and corresponding straight-tooth groove engagement.Gear clockwise rotates and be volume lock opening when straight-tooth meshes with corresponding hypotenuse.
Compared with prior art, the utlity model has following beneficial effect: owing to adopt the meshed transmission gear structure, the tooth bar of gear and left and right pull bar is in engagement all the time, there is not neutral state, so the bounce that acts on the left and right pull bar does not influence its motion process, therefore, slim coil brake lock moving process of the present utility model is very smooth and easy, laborsaving, reliable, simultaneously, just level and smooth contact between the movement parts, do not impact, not easy to wear, thereby durable.

The specific embodiment
By following embodiment the utility model is further elaborated.
The structure of a slim coil brake lock of embodiment of the utility model is referring to Fig. 3, Fig. 4, Fig. 5, shown in Figure 6.Insert the square hole of shifting block 18 central authorities when outer lock gall core after, the clockwise direction key, the groove 19 of shifting block 18 rotates by pin 17 driven gears 13, till two tooth bars, the 12 relative inwardly motions of gear 13 engagement were in straight-tooth 16 enters corresponding straight-tooth groove 14, coil brake lock was opening.When the counter clockwise direction key, the groove 20 of shifting block 18 is by 13 counter-rotatings of pin 17 driven gears, and relatively outwards motion is till straight-tooth 16 enters on the corresponding hypotenuse 11 two tooth bars 12, and at this moment, coil brake lock is locked state.
