Description
Technical field
The utility model relates to a kind of automatic rebounding rack anti-theft lock device.
Background technology
Existing Teethed bolt lock when mounted operation is loaded down with trivial details, must weld rack slide in advance before installation on steel plate; Existing Teethed bolt lock must be holed when installing gear on steel plate, and the error produced in boring procedure easily causes the fit clearance of wheel and rack excessive or too small, causes wheel and rack to occur tooth or biting teeth phenomenon, causes switch not smooth; The tooth mouth direction of existing Teethed bolt lock tooth bar upwards, in use comparatively large by such environmental effects, when particularly running into rain, snow, airborne dust weather, external dust and particle easily enter in the fit clearance of rack and pinion, increase the resistance of tooth bar, make Teethed bolt lock switch not smooth; Circularhole diameter on existing Teethed bolt lock tooth bar is in 15-16 millimeter, and spline thicknesses only has 18 cm, and therefore the circular hole both sides wall of tooth bar generally only has 1-1.5 millimeter, so impact resistance extreme difference, very easily fractures by brute force attack hour rack; Must use with two hand synchronous matching when existing Teethed bolt lock is opened, a hand rotates key, and another hand rotates door lock handball, is not suitable for old man, children and physical disabilities especially and uses; Existing Teethed bolt lock needs key to rotate very large angle when locking.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of automatic rebounding rack anti-theft lock device, lock body, tooth bar, rack slide, gear, lock fork mechanism, locking mechanism, automatic rebounding mechanism etc. can ideally be incorporated in a total system by it, fundamentally solve old-fashioned Teethed bolt lock installation procedure loaded down with trivial details, opening and closing are wasted time and energy, the design defect that inconvenience uses.
Accompanying drawing illustrates:
Fig. 1 is one of structural representation of a kind of automatic rebounding rack anti-theft lock device.
Fig. 2 is one of structural representation of a kind of automatic rebounding rack anti-theft lock device.
Fig. 3 is one of structural representation of a kind of automatic rebounding rack anti-theft lock device.
Fig. 4 is one of structural representation of a kind of automatic rebounding rack anti-theft lock device.
Number in the figure is: rack slide (1), tooth bar (2), gear (3), snail wind spring (4), pulling plug (5), spring (6), making leaf spring (7), location lock fork (8), lock lock fork (9), gear adjustment sheet (10), front and back fork shift sheet (11).
Detailed description of the invention:
The technical scheme that the utility model solves the employing of its technical problem is: a kind of automatic rebounding rack anti-theft lock device, comprises rack slide (1), tooth bar (2), gear (3), snail wind spring (4), pulling plug (5), spring (6), making leaf spring (7), location lock fork (8), locks the devices such as lock fork (9), gear adjustment sheet (10), front and back fork shift sheet (11): rack slide (1) is positioned at above lock body; Tooth bar (2) is inner through rack slide (1), and tooth bar (2) below is provided with two circular holes (12,13); Gear (3) is positioned on the right side of lock body, is engaged with tooth bar (2); Gear (3) is provided with snail wind spring (4), snail wind spring (4) end is fixed on lock body right side edge; Locating lock fork (8) and locking lock fork (9) is positioned on the left of lock body, location lock fork (8) ring set spring (6), the making leaf spring (7) of spring (6) top connects the pulling plug (5) of lock body outside; Lock lock fork (9) right side and be provided with two circular holes (15,16), on the right gear adjustment sheet (10), bossing (14) agrees with mutually with the circular hole locked in lock fork left; Front and back fork shift sheet (11) are positioned at locks lock fork (9) right side, is fixed on lock body, is connected with lock body external key jack.The tooth mouth of described tooth bar (2) is engaged with gear (3) downwards.Described tooth bar (2) all slide to rack slide (1) interior time, location lock fork (8) can automatically enter tooth bar (2) below a circular hole (12) in, realize locking function; When rotating clockwise key or drop-down pulling plug (5), location lock fork (8) is pulled open downwards, and scrollwork spring (4) can rotate by driven gear (3), and tooth bar (2) will automatic rebounding, realizes unlocking function.When rotating counterclockwise key, described front and back fork shift sheet (11) rotate clockwise, lock lock fork (9) upwards to be stirred, when locking lock fork (9) and being struck to the circular hole (13) of tooth bar (2) below, circular hole (16) with on gear adjustment sheet (10) left bossing (14) be engaged, just can realize back locking function; When rotating clockwise key, front and back fork shift sheet rotates counterclockwise, lock lock fork (9) to be stirred downwards, when locking circular hole (13) that lock fork (9) departs from below tooth bar completely, circular hole (15) with on gear adjustment sheet (10) left bossing (14) be engaged, can realize remove back locking function.
Good effect of the present utility model is: this Teethed bolt lock does not need to weld rack slide and theftproof lock in addition when mounted; This Teethed bolt lock has automatic resilience function when opening; This Teethed bolt lock has the strong premium properties of anti-impact force compared with old-fashioned Teethed bolt lock; This Teethed bolt lock only needs a hand operation in use, and switch is smooth and easy, and open and close, key only need rotate very little angle (about 45 degree) when locking, and is convenient to old man, child and physical disabilities' use; The tooth mouth of this Teethed bolt lock tooth bar is downward, has excellent dust reduction capability; This Teethed bolt lock has the little advantage of volume; This Teethed bolt lock is compared with old-fashioned Teethed bolt lock, and installation effectiveness improves more than 3 times.
