Abstract
The utility model relates to a kind of memory key of ratchet-type, comprise turn, fixedly inner core and outer sleeve, on wherein turning, key core and ratchet are installed, ratchet, control lever and spring leaf are fixedly installed on inner core.The utility model can record the on off state of door, selects in use different working methods, and device whole height is integrated, and that can do is very little, and the information of record is difficult for losing, and reliability is high, easy to use.The mode of on off state of checking door is directly perceived, and the information of record is reliable, easy to operate, and all parts are all detachable, be easy to safeguard, service time can be very long, and can when changing key, only change key core, and tape deck can be constant, greatly reduces use cost.
Description
Technical field
The utility model belongs to field of lockset, especially a kind of memory key of ratchet-type.
Background technology
In people's go off daily process, conventionally all be unable to do without door lock & key, but along with the kind of lock is more and more, people are sometimes difficult to judge whether door lock is locked really, causes unnecessary operation, even causes the damage of lockset or key.
Meanwhile, along with rhythm of life is more and more faster, various pressure is increasing, and need to process a lot of things every day, the too worried lock of probably door being forgotten of going out every day, and oneself has closed clearly sometimes, but not steady and sure at heart, and the number of times that goes back to check is not within minority.Yet except in person going to check, there is no other way, a large amount of time of waste for no reason at present.Thereby in the urgent need to a kind of memory key that can record the on off state of door lock, whether door closes, look at oneself just used key just know, save the plenty of time, and allow people more feel at ease.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of can body a kind of memory key of ratchet-type of less and convenient operation.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of memory key of ratchet-type, comprise and turning, fixedly inner core and outer sleeve, key core and ratchet are installed on wherein turning, fixedly on inner core, ratchet is installed, control lever and spring leaf, on outer sleeve, lower both ends of the surface are coaxially installed with respectively upper end cover and bottom end cover, in sleeve, be coaxially installed with fixedly inner core, in fixing inner core middle part coaxial rotation, installing one turns, on this is turned, lower both ends of the surface are the coaxial ratchet of installing respectively, two ratchets are reverse, fixedly inner core both ends of the surface are installed respectively one and are taken turns the ratchet of locating with this gemmule, two ratchets all press down by a shell fragment crimping realizing with ratchet, between two shell fragments, install one with the fixing homoaxial control lever of inner core, on the corresponding fixedly inner core of this control lever position, be shaped with and place this control lever groove, described key core is coaxially arranged on the lower end of turning, on the corresponding outer sleeve of control lever position, be provided with opening, the button that can drive control lever to swing is installed on the control lever position of this opening part.
And two ratchets be take control lever and are arranged axisymmetricly as axle.
And, in the described upper end of turning, be coaxially installed with handle.
Advantage of the present utility model and good effect are:
1, the utility model can record the on off state of door, selects in use different working methods, and device whole height is integrated, and that can do is very little, and the information of record is difficult for losing, and reliability is high, easy to use.The mode of on off state of checking door is directly perceived, and the information of record is reliable, easy to operate, and all parts are all detachable, be easy to safeguard, service time can be very long, and can when changing key, only change key core, and tape deck can be constant, greatly reduces use cost.
2, the utility model is selected to open the door or close the door by button, drive control lever, spring leaf compresses ratchet to ratchet, form ratchet mechanism, this be can only be when one-directional rotation carry-over moment, other direction non-moment, free to rotate, open or close when checking the button of used this key just like this, can judge and just now whether carry out door-closing operation, thereby determine the on off state of door.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is ratchet in the utility model and the working state schematic representation of click-fit;
Fig. 3 is the working state schematic representation that the control lever in the utility model drives ratchet.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of memory key of ratchet-type, comprise turn (not label), fixedly inner core 4 and outer sleeve 5, wherein, key is installed on turning, 1 with ratchet 2, ratchet 3 is fixedly installed on inner core, control lever 10 and spring leaf 7, on outer sleeve, lower both ends of the surface are coaxially installed with respectively upper end cover 8 and bottom end cover 9, in sleeve, be coaxially installed with fixedly inner core, in fixing inner core middle part coaxial rotation, installing one turns, on this is turned, lower both ends of the surface are the coaxial ratchet of installing respectively, two ratchets are reverse, fixedly inner core both ends of the surface are installed respectively one and are taken turns the ratchet of locating with this gemmule, two ratchets all press down by a shell fragment crimping realizing with ratchet, between two shell fragments, install one with the fixing homoaxial control lever of inner core, on the corresponding fixedly inner core of this control lever position, be shaped with and place this control lever groove, two ratchets be take control lever and are arranged axisymmetricly as axle, described key core is coaxially arranged on the lower end of turning, on the corresponding outer sleeve of control lever position, be provided with opening, the button 6 that can drive control lever to swing is installed on the control lever position of this opening part.
For the ease of hand-held, turning, upper end is coaxially installed with handle.
On button, be provided with switch mark.
Operating principle of the present utility model is:
By button, select to open the door or close the door, drive control lever, spring leaf compresses ratchet to ratchet, form ratchet mechanism, this be can only be when one-directional rotation carry-over moment, other direction non-moment, free to rotate, open or close when checking the button of used this key just like this, can judge and just now whether carry out door-closing operation, thereby determine the on off state of door.Thisly check that the mode of on off state of door is directly perceived, the information of record is reliable, easy to operate, and all parts are all detachable, be easy to safeguard, service time can be very long, and can when changing key, only change key core, and tape deck can be constant, greatly reduces use cost.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
