Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
The first embodiment is as follows:
as shown in fig. 1 to 4, a key storage device convenient for one-handed operation includes a housing 10, a first key blade 40 and a first driving device; the shell 10 is provided with a containing cavity 101, the shell 10 is provided with a first extending hole 11 and a first yielding hole 13, the first extending hole 11 and the first yielding hole 13 both penetrate through the side wall of the shell 10 and extend into the containing cavity 101, the first yielding hole 13 is positioned on one side of the shell 10, and the first extending hole 11 is positioned at the upper end part of the shell 10; a first sliding groove is formed in the inner side wall of the shell 10, the first key strip 40 is slidably arranged in the first sliding groove, the first sliding groove is used for limiting the movement track of the first key strip 40, when the first key strip 40 slides towards the outside of the shell 10 along the first sliding groove, the first key strip can extend out of the shell 10 through the first extending hole 11, a first return spring 41 is arranged in the first sliding groove, one end of the first return spring 41 is connected in the shell 10, the other end of the first return spring is connected on the first key strip 40, the first return spring 41 can pull back the first key strip 40 when the first key strip 40 loses external force, so that the first key strip is reset, and a first rack 401 is formed in one side of the first key strip 40; the first driving device comprises a first driving knob 20, a first driving wheel 21 and a first transition wheel 22, the first driving knob 20 is rotatably arranged in the first avoiding hole 13, at least part of the first driving knob 20 is exposed out of the casing 10 so as to facilitate shifting of the first driving knob 20 during use, as shown in fig. 4, the first driving wheel 21 is coaxially and fixedly arranged on the first driving knob 20, when the first driving knob 20 rotates, the first driving wheel 21 synchronously rotates, the first transition wheel 22 is rotatably arranged in the accommodating cavity 101, the first transition wheel 22 is positioned between the first driving wheel 21 and the first rack 401, the first driving wheel 21 is meshed with the first transition wheel 22, the first transition wheel 22 is meshed with the first rack 401, and when the first driving wheel 21 rotates, the first key strip 40 is driven to slide along the first sliding groove.
Under normal conditions, the first key strip 40 will be positioned in the housing 10 by the pulling force of the first return spring 41. When a key needs to be taken, only the first driving knob 20 needs to be pulled, the first driving knob 20 rotates to drive the first driving wheel 21 to rotate, the first driving wheel 21 drives the first transition wheel 22 to rotate, and the first transition wheel 22 drives the first rack 401 to further drive the first key strip 40 to move, so that the first key strip 40 is exposed out of the shell 10, and the key is used.
Example two:
on the basis of the first embodiment, in order to accommodate more keys, the present embodiment further includes a second key strip 50 and a second driving device, the housing 10 is further provided with a second extending hole 12 and a second yielding hole 14, the inner side wall of the housing 10 is provided with a second sliding groove, the second key strip 50 is slidably disposed in the second sliding groove, a second return spring 51 is disposed in the second sliding groove, one end of the second return spring 51 is connected in the housing 10, the other end of the second return spring is connected to the second key strip 50, and one side of the second key strip 50 is provided with a second rack 501; the second driving device comprises a second driving knob 30, a second driving wheel 31 and a second transition wheel 32, the second driving knob 30 is rotatably arranged in the second avoiding hole 14, at least part of the second driving knob 30 is exposed out of the shell 10, the second driving wheel 31 is coaxially and fixedly arranged on the second driving knob 30, the second transition wheel 32 is rotatably arranged in the accommodating cavity 101, the second transition wheel 32 is positioned between the second driving wheel 31 and the second rack 501, the second driving wheel 31 is meshed with the second transition wheel 32, the second transition wheel 32 is meshed with the second rack 501, and when the second driving wheel 31 rotates, the second key strip 50 is driven to slide along the second sliding groove. The using principle is similar to that of the first embodiment, and is not described in detail.
Example three:
on the basis of the second embodiment, as shown in fig. 4, since the length of the first key bar 40 or the second key bar 50 required to extend out of the housing 10 is long, and the stroke of the human hand capable of continuously dialing the first driving knob 20 or the second driving knob 30 in a single time is limited when in use, in order to conveniently drive the first key bar 40 and/or the second key bar 50 to extend out of the housing 10, the diameter of the first driving wheel 21 is larger than that of the first transition wheel 22 in this embodiment; the diameter of the second driving wheel 31 is larger than that of the second transition wheel 32, so that the first driving knob 20 and/or the second driving knob 30 can rotate a smaller number of turns to drive the first transition wheel 22 to rotate a larger number of turns, and finally the first key strip 40 and/or the second key strip 50 can be rapidly driven to move.
Example four:
as shown in fig. 3, since the first drive wheel 21 and the second drive wheel 31 are all-gear wheels, when the first key blade 40 and the second key blade 50 are reset, since the meshing of the gears requires the first drive knob 20 and the second drive knob 30 to be rotated in opposite directions to achieve reset, there are many inconveniences in use, and therefore, on the basis of the first, second or third embodiment, the first driving wheel 21 and/or the second driving wheel 31 are both partially toothed, when the gear parts are engaged, the first key strip 40 and/or the second key strip 50 are normally brought into motion, when the first drive wheel 21 and/or the second drive wheel 31 rotate to the toothless part, the first transition wheel 22 and/or the second transition wheel 32 lose the meshing force and the first key blade 40 and/or the second key blade 50 are/is reset by the first return spring 41 and/or the second return spring 51.
Example five:
in order to prevent the first drive knob 20 and/or the second drive knob 30 from being rotated to the preset position by the hand which cannot be driven by a single time, the first drive knob 20 and/or the second drive knob 30 loses the action of external force during the period of driving and lifting the finger for a plurality of times at intervals, so that the first key bar 40 and/or the second key bar 50 generates the reset movement under the action of the first reset spring 41 and/or the second reset spring 51, therefore, in the embodiment, the first drive knob 20 and the second drive knob 30 are rotatably arranged on the housing 10 through the damping rotating shaft. The damping rotating shaft can generate certain resistance to prevent the first rack 401 and/or the second rack 501 from being accidentally reset under the action of the first return spring 41 and/or the second return spring 51.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
