Description
Technical field
The present invention relates to a kind of daily life tools, specifically a kind of key chain.
Technical background
In daily life, key chain is the requisite one way of life apparatus of people, nowadays also has key chain miscellaneous to occur in the life of people.But people use during these key chains and face a problem, exactly when key being put into or taking out key chain, because the strength ratio of the material of clasp own is higher, the opening of clasp is difficult to open, and therefore puts into key or takes out clasp and become a very hard thing; Some clasp aperture efficiency is easier to open, and reason is that the intensity of grommet material own is not high, but the easy like this key that makes is deviate from without artificial and lose from clasp.Therefore be necessary to design on the basis of existing technology the key chain that key is put into or taken out clasp by a kind of people of being convenient to, and keep the intensity of key chain itself, namely keep the reliability that it uses.
Summary of the invention
Goal of the invention: the object of the invention is to provide a kind of key chain being convenient for people to be put into by key or take out clasp, and keep the dependability of key chain itself.
Technical scheme: in order to achieve the above object, the present invention specifically adopts following technical scheme:
A kind of key chain, is characterized in that, comprising:
Clasp, its head is provided with one with described clasp radial direction towards consistent hinge hole, and at described hinge hole, described clasp rear direction is provided with a recess, forms face table top upward;
Stir bar, its thickness is consistent with described clasp, its afterbody is provided with a hinge hole, and it is hinged by the hinge hole of a hinged nail and described clasp head, the end of its afterbody is provided with a projection, be positioned at above table top that described clasp head is arranged, described in stir when bar upwards stirs described projection can by described table top hold make described in stir bar and stop operating;
Permanent magnet, is arranged on described clasp afterbody, and stirs the below of bar described in being positioned at, and described permanent magnet thickness is less than described clasp thickness, and embeds in described clasp.
Preferred scheme is: described key chain, it is characterized in that, described clasp head and the described hinge portion stirring bar head are respectively arranged with and suit face, the described vertical line direction suiting face is the radial direction of described clasp, make described clasp head and the described thickness stirring the hinge portion of bar afterbody be less than its body thickness and, described clasp head and described stir bar afterbody hinged after, its lateral surface keeps smooth, thus maintaining attractive in appearance, two suit face hinged after, its thickness of adding up will be thicker than body thickness, the height that reinforcement arches upward is to clasp radially inner side, thus maintaining hinged face and have enough thickness to keep its intensity.
Preferred scheme is: described key chain, it is characterized in that, described clasp toward caudal directions around as described stir bar engagement point time, one knuckle oblique is downwards set, the lower surface of described clasp at this position is along described knuckle to downward-extension, its upper surface and describedly stir the smooth joint of bar upper surface, stir the cross section that bar engages be arranged to arc-shaped with described, the axis of camber line place circle of this circular arc and the radial parallel of described clasp, its arc opening stirs bar side and this arc is minor arc to described, the upper inclined surface of the described end cross-sectional and described knuckle of stirring bar head suits and has the arc section matched with its circular arc cross-sections, described clasp afterbody to be connected to below described knuckle and clasp head described in extend through, form a complete ring buckle.The advantage of this design is, dig when the described flip bar key that can not be buckled in described clasp is slided, and the lines can placed on clothing enter gap, composition surface and are dug by the described bar that stirs, even if the lines of clothing enter gap, because faying face is arc-shaped, its arc opening stirs bar side to described, and lines are also difficult to the described bar that stirs to open.
Preferred scheme is: described key chain, it is characterized in that, the described bar iron that stirs is made, the position of described permanent magnet near described in stir bar head one end, according to lever principle, permanent magnet is the closer to the described head stirring bar, stir bar described in just firmly holding, make it only could be dug when manpower overturns.
Preferred scheme is: described key chain, it is characterized in that, the end cross-sectional of described clasp head makes an inclined-plane, described inclined-plane down, stir described in making bar stir rear described inclined-plane and described stir bar downside coincide, keep its planarization, prevent from being stuck when stirring bar described in keyhole passes and sliding to described clasp cephalad direction and cannot slipping into smoothly in described clasp.
Preferred scheme is: described key chain, it is characterized in that, the lower surface at described clasp head rear is provided with V-arrangement recess III, Open Side Down and to described clasp head back sweep for its V-arrangement, the relevant position being positioned at the described clasp afterbody immediately below described V-type recess I is provided with V-type recess II, its V-arrangement opening upwards and to described clasp head back sweep.The use of this design is, prevent from key from raising described clasp afterbody to skid off toward described clasp head side and come off and lose, even if described clasp elastic strength reduces after metal fatigue, described clasp afterbody is easily raised, key between described clasp afterbody and clasp head to head one Slideslip time, existence due to V-arrangement recess makes key cannot be continued to slide by card master, but because the opening of V-arrangement recess is toward rear portion, so key can not be hindered to be slipped in clasp to described clasp afterbody by described clasp head.
Key chain of the present invention, with the guiding port stirring active open that bar arranges a clasp and slide as key, and coordinate magnetic component to make it to open smoothly and firmly close, carry out on the basis of existing technology improving and solve an existence problem for a long time, namely the problem being difficult to open clasp mouth when clasp is put into or taken out to key is solved, and this key chain can only slide into key by clasp head to clasp afterbody or skid off key under artificial action, it is the key chain of a unidirectional turnover, easy to use, safe and reliable.
