Description
Technical field
The utility model relates to consumer goods industries, more particularly, relates to a kind of automatically cleaning stretchable key.
Background technology
In daily life, some important keys are often placed separately, but the key placed separately is long-time contact with air and use after, be easy to dirty.And the key ratio placed separately is easier to lose, more local to other than being easier to stamp again when not needing to use.
Utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of automatically cleaning stretchable key.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of automatically cleaning stretchable key, this stretchable key comprises housing and collapsible teeth portion in this housing, this housing side is provided with the opening stretched out for this teeth portion, and this opening part dual-side is installed with the cleaning brush be oppositely arranged with this teeth portion respectively; This teeth portion top is connected by the first spring with this inner walls, this teeth portion is provided with tooth bar, be provided with in this housing and can rotate in this housing and the ratchet coordinated with this tooth bar, this ratchet is rotatably connected by the first rotating shaft and this housing, this ratchet is fixed in this first rotating shaft, and this first rotating shaft one end extend out to this surface of shell formation button, this first rotating shaft other end is abutted by the second spring with this inner walls; The throw-out lever limiting the reversion of this ratchet is provided with in this housing.
In automatically cleaning stretchable key described in the utility model, this housing is also provided with hanging hole.
In automatically cleaning stretchable key described in the utility model, this cleaning brush comprises the first brush body and the second brush body, and this first brush body and the second brush body are arranged at the both sides of this teeth portion respectively, is provided with the 3rd spring between this first brush body and second brush body.
In automatically cleaning stretchable key described in the utility model, this second spring one end is sheathed in this first rotating shaft, and this second spring one end is fixedly connected with this inner walls.
Implement automatically cleaning stretchable key of the present utility model, there is following beneficial effect: when using automatically cleaning stretchable key of the present utility model, can manually teeth portion be pushed in housing, the rack drives pawl wheel in push-on process in teeth portion, now, because ratchet is for rotating forward, throw-out lever can not limit the rotation of ratchet, until teeth portion is driven fully into in housing, due to the reversion of throw-out lever restriction ratchet, therefore, teeth portion is limited to shrink in housing.When needs use key, press button downwards, sour jujube wheel and rack is departed from meshing, now teeth portion again extend out to outside housing under the elastic-restoring force effect of the first spring.Stretch out in teeth portion and be contracted in the process inside and outside housing, cleaning brush cleans the foreign matter in teeth portion, plays the effect of automated cleaning.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the Facad structure schematic diagram of the utility model automatically cleaning stretchable key.
Fig. 2 is the side structure schematic diagram of the utility model automatically cleaning stretchable key.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, 2, in automatically cleaning stretchable key first embodiment of the present utility model, this stretchable key 1 comprises housing 2 and collapsible teeth portion 3 in this housing 2, this housing 2 side is provided with the opening 4 stretched out for this teeth portion 3, and this opening 4 place dual-side is installed with the cleaning brush 5 be oppositely arranged with this teeth portion 3 respectively; This teeth portion 3 top is connected by the first spring 6 elasticity with this housing 2 inwall, this teeth portion 3 is provided with tooth bar 7, be provided with in this housing 2 and can rotate in this housing 2 and the ratchet 8 coordinated with this tooth bar 7, this ratchet 8 is rotatably connected with this housing 2 by the first rotating shaft 9, this ratchet 8 is fixed in this first rotating shaft 9, and this first rotating shaft 9 one end extend out to this housing 2 surface formation button 10, this first rotating shaft 9 other end is abutted by the second spring 11 elasticity with this housing 2 inwall; The throw-out lever 12 limiting the reversion of this ratchet 8 is provided with in this housing 2.
When using automatically cleaning stretchable key 1 of the present utility model, can manually teeth portion 3 be pushed in housing 2, tooth bar 7 in push-on process in teeth portion 3 drives ratchet 8 to rotate, now, because ratchet 8 is for rotating forward, throw-out lever 12 can not limit the rotation of ratchet 8, until teeth portion 3 is driven fully into in housing 2, reverse because throw-out lever 12 limits ratchet 8, therefore, teeth portion 3 is limited to shrink in housing 2.When needs use key 1, pressing button 10 downwards, make ratchet 8 and tooth bar 7 depart from meshing, now teeth portion 3 again extend out to outside housing 2 under the elastic-restoring force effect of the first spring 6.Stretch out in teeth portion 3 and be contracted in the process inside and outside housing 2, the foreign matter in cleaning brush 5 pairs of teeth portion 3 cleans, and plays the effect of automated cleaning.
Further, the throw-out lever 12 made for elastic plastic material of this throw-out lever 12.
Further, this housing 2 is also provided with hanging hole 13.
Further, this cleaning brush 5 comprises the first brush body 14 and the second brush body 15, and this first brush body 14 and the second brush body 15 are arranged at the both sides of this teeth portion 3 respectively, is provided with the 3rd spring 16 between this first brush body 14 and second brush body 15.
Further, this second spring 11 one end is sheathed in this first rotating shaft 9, and this second spring 11 one end is fixedly connected with this housing 2 inwall.
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 utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
