Abstract
The utility model relates to a zipper head with a locking device which comprises a combination forcing device, a spring, a braking hook, a lock core, a cover plate, etc. The spring, the braking hook and the lock core are arranged in a hollow cavity on the upper end of the combination forcing device in sequence, and then the hollow cavity is closed by the cover plate. The lock core is rotated by a key in special shape to change the length of the spring, and consequently, the braking hook is abutted and pressed by the spring to move upwards and downwards. When the braking hook hooks a zipper tooth downwards, a zipper is locked, when the braking hook moves upwards, the zipper is unlocked, so the operation of the utility model is very simple and convenient. Besides, only a plurality of small components are added on a common zipper head, so the utility model has the characteristics of small volume, low cost and simple structure.
Description
The utility model is a kind of slider of zipper fastener, especially a kind of slider of zipper fastener of deciding device with lock.
The slide fastener purposes is very extensive, mainly be to be used to seal on article such as bag, case, need zip-lock in many cases, in case other people at will draw back slide fastener, the someone has designed some slider of zipper fasteners with lock for this reason, guaranteed that slide fastener can not arbitrarily be drawn back by other people, but these slider of zipper fasteners with lock construction mostly comparatively complicated, the slider of zipper fastener volume is also bigger, and is comparatively heavy, the locking and unlocking operation of slide fastener is also inconvenient, so and fail to be used widely.
The purpose of this utility model is to provide that a kind of volume is little, cost is low, and simple in structure, the locking and unlocking is slider of zipper fastener easily.
Realize that scheme of the present utility model is: whole slider of zipper fastener comprises by base plate, upper plate is formed compels to close device, the spring of forming lock body structure, arrester hook, lock core and cover plate, compeling to close device upper plate one end is a cavity, have a vertical bar shape mouth on the wall of cavity by the slide fastener side of drawing back, cavity bottom is established a cylinder chamber, spring places in the cylinder chamber, the tail end of arrester hook is pressed on the spring, hook is rectified compeling to close the hole that the device upper plate is left, lock core is a cylindricality piece, its bottom is a slope, the top is provided with a keyhole, lock core places in the cavity and pushes down the arrester hook tail end, have on the cover plate one with the identical hole of lock core keyhole shape, cover plate places compels to close device upper plate cavity top, and cavity is sealed.
The utility model is owing to directly be provided with arrester hook compeling to close on the device, and by being enclosed in moving up and down of lock core control arrester hook in the cavity.And lock core needs the key of special shape to rotate, thus move downward when arrester hook, hook zipper teeth after, slide fastener just can not draw back, and has guaranteed that slide fastener is not arbitrarily drawn back by other people, and arrester hook upwards, leave zipper teeth, then slide fastener can draw back again smoothly, closure, and the locking and unlocking is very convenient, the utility model only needs to compel to close the several widgets of increase on the device at zipper head in addition, therefore it can realize that volume is little, and cost is low, purpose simple in structure.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is vertical views of the present utility model.
Below in conjunction with accompanying drawing the utility model structure and the course of work are described in further detail.
As shown in drawings, the utility model includes compels to close device (1), spring (2), arrester hook (3), lock core (4) and cover plate (5), the upper end of wherein compeling to close device (1) is a cavity (6), drawing back on the direction by slide fastener, open a vertical bar shape mouth (9) on cavity (6) wall, be provided with a cylindrical cavity (7) again in the bottom of cavity (6), spring (2) is placed vertically in cylindrical cavity (7), cavity (7) makes spring (2) keep erectting shape, the drift of spring (2) is greater than the degree of depth of cavity (7), arrester hook (3) is a bullion sheet, it places the bottom of cavity (6), one of buckle is rectified slide fastener is compeled to close the aperture (8) that device (1) upper plate leaves, the tail end of arrester hook then places on the spring (2), and contact with spring (2), the middle part of arrester hook (3) is supported on the edge of cavity (6) vertical bar shape mouth (9) bottom, arrester hook (3) is just just as a lever like this, can rotate around support place at middle part, lock core (4) is a column piece, its bottom is a slope, the top is provided with a keyhole, whole lock core (4) places in the cavity (6) and is pressed in the tail end of arrester hook (3), cover plate (5) be provided with one with the identical hole of lock core (4) keyhole shape, cover plate (5) is fixed on cavity (6) upper end, with cavity (6) sealing, and push down lock core (4), and then extruding arrester hook (3) tail end makes spring (2) be in confined state.
The utility model in use, when the slide fastener closure is needed locking, be available one to insert from keyhole with the identical shaped key of keyhole, rotational lock core (4), because the bottom of lock core (4) is a slope, when turning to the position of the compressed degree minimum of spring (2), upwards resilience of spring (2) causes the tail end of arrester hook (3) to rise.The hook end of arrester hook (3) descends like this, and compel to close in the aperture (8) that device (1) upper plate leaves by slide fastener and move downward, can hook zipper teeth, slide fastener is just locked like this, opens as need, as long as insert keyhole with key, lock core (4) is gone back to, then the bottom slope of lock core (4) is subdued arrester hook (3) tail end again again, and the hook end is raised, leave zipper teeth, then slide fastener can draw back smoothly with compeling to close the motion of device (1) again, closure.
Locate better in order to make arrester hook (3), its hook end can compel to close aperture (8) turnover of device (1) upper plate exactly from slide fastener in moving up and down, about the middle part of arrester hook (3), respectively establish a projection, and the projection card is placed in the left and right edges, cavity (6) vertical bar shape mouth (9) bottom, arrester hook (3) just can not seesaw like this, rotates and can only do lever-like around the position of projection.
Claims (2)
1, a kind of slider of zipper fastener with lock, comprise by base plate, upper plate is formed compels to close device (1), it is characterized in that also including the spring (2) of forming lock body structure, arrester hook (3), lock core (4) and cover plate (5), the upper end of compeling to close device (1) is a cavity (6), on the wall of cavity (6), open a vertical bar shape mouth (9) by the slide fastener side of drawing back, the bottom of cavity (6) is provided with a cylinder chamber (7), spring (2) is perpendicular to be placed in the cylindrical cavity (7), arrester hook (3) tail end is pressed on the spring (2), hook is rectified compeling to close the hole (8) that device (1) upper plate leaves, lock core (4) places in the cavity (6), its bottom is a slope, the top is provided with a keyhole, the bottom slope is pushed down and is cutd open hook (3) tail end, cover plate (5) be provided with one with the identical hole of lock core (4) keyhole shape, cover plate (5) places compels to close device (1) upper plenum (6) top, and cavity (6) is sealed.
