From foregoing description, the beneficial effects of the utility model are: the utility model provides a kind of mechanical rotational structure, comprise roller 4 and the fixed wheel 7 of coaxial setting, therebetween coordinated by unidirectional helical teeth 14 and be fixedly connected with, fixed wheel 7 is spacing by keeper 9, can only move forward and backward in the horizontal direction along keeper 9 chute 16, said structure limits described roller 4 and can only rotate toward a direction in normal conditions; And by being fixedly installed magnetic metal part 8 on fixed wheel 7, and be fixedly installed electromagnet 11 in the position that keeps at a certain distance away along the bearing of trend of d-axis 5, magnetic attraction will be produced after electromagnet 11 is energized, fixed wheel 7 is driven to move backward, fixed wheel 7 and roller 4 are departed from, reaches the object that roller 4 rotates freely.Said structure is equipped with in the concave part of lock body, can be fixed in groove by device lock by the single direction rotation of roller 4, and unlocks when being energized, and can pass through the upset extraction device of roller 4, thus the light lock and unlock easily of the equipment that realizes.The mechanical rotational structure of one described in the utility model and lockset, not only structure is simple, small and exquisite, better can popularize use; And enhance security performance, can be good at preventing from illegal molecule picking lock or cut lock stealing equipment, further, the utility model can be good at being used in the unified management of shared device, and the neat setting of overall arrangement, improve the appearance of the city city's looks, has good utilization prospect at municipal design field.
Further, described magnetic metal part 8 is U-shaped magnetic metal pull bar, and described U-shaped magnetic metal pull bar is made up of curved portions and two line parts; Described nose bar 15 offers the through hole 17 suitable with two line parts of described U-shaped magnetic metal pull bar, described line part through described through hole 17, and is fixedly installed on described fixed wheel 7 by being threaded in curved portions.
Seen from the above description, U-shaped magnetic metal pull bar passes through hole 17 by two line parts, and nutted connected mode is fixedly installed on fixed wheel 7 in curved portions, what ensure that U-shaped magnetic metal pull bar can be firm is fixed on fixed wheel 7, and durable in use, extend the application life of described mechanical rotational structure.
Further, described roller 4 is made up of outer ring hexagonal roller 4 and inner ring helical teeth 14.
Seen from the above description, the helical teeth 14 of inner ring matches with the unidirectional helical teeth 14 of fixed wheel 7, can only realize single direction rotation; And the design that outer ring is hexagonal roller 4 is used in when lockset uses as lock core, can be good at the stroke shortening the locking bar coordinated with it, and locking bar is unlikely to too thin, can not be cut off by illegal molecule easily; Meanwhile, hexagonal roller 4 is also convenient to produce, and has good Practical Performance in practice scene.
Further, described keeper 9 is two chute 16 fixed blocks, and described chute 16 fixed block is fixed on sidewall corresponding with described nose bar 15 in housing 1.Keeper 9 is the internal construction that the design of chute 16 fixed block simplifies mechanical rotational structure.
Further, described elastic component 10 is for playing ring 18, and described d-axis 5 is through the cavity of described bullet ring 18; One end of described bullet ring 18 is fixedly connected with described fixed wheel 7, and the other end is fixedly connected with the sidewall of described housing 1.
From the above, elastic component 10 is the design playing ring 18, d-axis 5 directly can be allowed by cavity, while can giving full play to elastic-restoring force, described mechanical rotational structure can be made again compacter.
Further, described roller 4, fixed wheel 7, keeper 9 and magnetic metal part 8 are pack alloy material.
Another technical scheme that the utility model provides is:
A kind of lockset, comprises lock body and above-mentioned mechanical rotational structure; Described lock body offers a concave part, and described mechanical rotational structure is fixedly installed in described lock body, and the described projection piece 12 of described mechanical rotational structure stretches in concave part with the direction of the cell wall 20 of vertical described concave part.
Preferably, described lock body offers a concave part, and described concave part forms by notch 19 with by the outward extending cell wall 20 of notch 19; Described mechanical rotational structure is fixedly installed in described cell wall 20, and the projection piece 12 of described mechanical rotational structure exceeds described cell wall 20 and arranges, exceeding apart from suitable of the distance between described cell wall 20 and described projection piece 12.The projection piece 12 of described mechanical rotational structure can carry out compliance configuration according to the utilization scene of reality, as long as can realize just can in the concave part being locked in lock body by lock assembly.
Operating principle of the present utility model is: mechanical rotational structure in default situations, by the fit system of helical teeth 14 unidirectional between roller 4 with fixed wheel 7 in conjunction with the setting of keeper 9 chute 16 make cam both sides projection piece 12 can only in the chute 16 of keeper 9 moving linearly, realize roller 4 and rotate towards a direction.Utilization on lockset, device lock is fixed in the concave part of lock body by the one-way movement of roller 4 projection part 12 by the equipment that can only realize, and cannot reverse unlocker device.After electromagnet 11 in machinery rotational structure is energized, magnetic force will be produced, magnetic force attracts the magnetic metal part 8 on fixed wheel 7, thus move after driving the fixed wheel 7 be fixedly connected with magnetic metal part 8, and then the helical teeth 14 of fixed wheel 7 helical teeth 14 and roller 4 is departed from completely, reach the object that roller 4 rotates freely.When being used on lockset, inserting energising by magnetic card, projection piece 12 bidirectional rotation of roller 4 can be made, equipment is taken out in the concave part of lock body, and recover default conditions after magnetic card is extracted.
Please refer to Fig. 4, embodiment one of the present utility model is:
A kind of lockset for public bicycle.Comprise vertical rod, vertical rod is provided with ring groove and draw-in groove, and ring groove comprises groove port 19 and cell wall 20; Bicycle is provided with closed railing 21, and in default situations, the railing 21 of bicycle is locked between the protruding angle of hexagonal roller 4 and groove port 19, is locked by bicycle thus.When people need to use car, special card is inserted in draw-in groove, the electromagnet 11 in lock core is made to obtain electric, produce suction, U-shaped magnetic metal pull bar on absorption fixed wheel 7, thus pull fixed wheel 7 to move backward, unidirectional helical teeth 14 between fixed wheel 7 and roller 4 is separated from, and roller 4 just can realize rotating, take out the automatic vehicle of locking easily, and after card taking-up, electromagnet 11 dead electricity, fixed wheel 7 recovers to coordinate with the helical teeth 14 of roller 4 owing to playing the reverse reverting power of ring 18 fast, and fixed wheel 7 returns to can only the state of single direction rotation.
In sum, the one machinery rotational structure that the utility model provides and lockset, not only structure is simple, small and exquisite, convenient universal use; And possess good security performance, effectively antitheft; Further, at municipal design field, there is good utilization prospect.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalents utilizing the utility model manual and accompanying drawing content to do; or be directly or indirectly used in relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
