Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
As Figure 1-4, a kind of folding key with limit function, including the shank of the key 100 and key bar 200, it is described
The shank of the key 100 is in strip, and the shank of the key 100 offers holding tank 110；
One end of the key bar 200 is hinged on one end of the shank of the key 100, and the key bar 200 can relatively described key
Handle 100 deploys and folding, and the holding tank 110 is used to accommodate the key bar 200 in 200 folding of key bar；
The position that the key bar 200 is articulated with the shank of the key 100 is rotation section 210, and the shank of the key 100 is provided with about
Beam block 120, the constraint block 120 are located at the top of rotation section 210, and the relatively described the shank of the key 100 of the key bar 200 is in exhibition completely
During open state, the constraint block 120 is interference fitted with the rotation section 210, keeps the key bar 200 phase in its natural state
For the key bar 200 in expansion shape.
The profile of rotation section 210 is in arc-shaped, the radian of the rotation section 210 and the key bar 200 and the shank of the key
100 relative rotation angle matches, and the rotation section 210 is using the hinge hole of key bar 200 as the center of circle, the rotation section 210
Top offers limiting section 220, and the limiting section 220 and the junction structure of the rotation section 210 are in cam structure；
The limiting section 220 includes vertical end 221 and horizontal ends 222, and the horizontal ends 222 are horizontally disposed, the level
The profile one end at end 222 is connected to the highest point of the cam structure of rotation section 210, and the horizontal ends 222 are positioned at described be hinged
Above hole, the horizontal ends 222 are tangential on the rotation section arc profile；The vertical end 221 is vertically arranged, the vertical end
221 profile both ends are connected to the other end of horizontal ends 222 and the key bar 200 edge.
Key bar 200 is exactly the unlocking part of common key, and this part is the metal of fine strip shape, and the key having is also
There is jagged edge, key bar 200 is articulated with the shank of the key 100, and key bar 200 is received into the shank of the key 100 when not in use,
Avoid that the sharp parts of key bar 200 have influence on other articles or itself is damaged；In addition, when key bar 200 is relative to key
When the shank of the key 100 is in deployed condition, the rotation section 210 for being arranged at key bar 200 and the constraint block phase interworking for being arranged at the shank of the key 100
Close, key bar 200 is kept the deployed condition of 180 degree, consequently facilitating user uses key；
Rotation section 210 is in arc-shaped, when key bar 200 when rotated, constraint block 120 does not interfere with the rotation of key bar 200
Turn, after the circular arc stroke of rotation section 210 terminates, limiting section 220 and constraint block 120 produce contact, when constraint block 120 relative to
When the stroke of rotation section 210 reaches limiting section 220, the horizontal ends 222 and constraint block of limiting section produce interference fit, and constrain
The vertical end 221 for being affixed on the limiting section is supported in the front end of block 120, makes user when using key, the He of key bar 200 after key stress
The relative position of the shank of the key 100 is stable, key is both provided with folder function, also preferable usage experience sense.
Wherein, when the relatively described the shank of the key 100 of the key bar 200 in opened condition when, the constraint block 120 is located at institute
The top of limiting section 220 is stated, the front end of constraint block 120 is sticked in the vertical end of the limiting section 220, the constraint block 120
Bottom is provided with round and smooth projection, and the projection is pushed against in the horizontal ends 222.
Only key bar 200 with respect to the shank of the key 100 in opened condition when, the bottom of constraint block 120 projection can just push against
In horizontal ends 222, the bottom of constraint block 120 uses round and smooth projection, and the bottom of constraint block 120 and horizontal ends 222 contact for point
Or linear contact lay, constraint block 120 and limiting section 220 smoothly can be gradually slided into interference during interference, so as to real
Now to the spacing of key bar 200.
In addition, the shank of the key 100 includes the first lateral plate 130 and the second lateral plate 140, first lateral plate 130 and second
Lateral plate 140, which is oppositely arranged, surrounds holding tank 110；The key bar 200 has bar-shaped trough；
The face that the lateral plate 140 of first lateral plate 130 and/or second is located in holding tank 110 is provided with projection 150, the key
For key lever 200 in when being folded in 100 state of the shank of the key, the projection 150 is caught in the bar-shaped trough of the key bar 200.
The bar-shaped trough of key bar 200 is the groove that most keys all possess or is to realize key bar 200 and the shank of the key
100 fasten and the grooves that open up, during its purpose is to ensure that key bar 200 is accommodated in the shank of the key 100, will not voluntarily produce, need
Key bar 200 can just be screwed out the shank of the key 100 by very important person for rotation.
Wherein, the shank of the key 100 is provided with link 160；
The link 160 is arranged at the shank of the key 100 in rounding off shape, and the integrated setting of link 160 is in institute
State the shank of the key 100.
Link 160 is used to hang key hook in key chain, or for other.
In addition, the shank of the key 100 includes the first lateral plate 130 and the second lateral plate 140, first lateral plate 130 and second
Lateral plate 140, which is oppositely arranged, surrounds holding tank 110；
The lateral plate 140 of first lateral plate 130 and/or second offers gap 170, and the gap 170 is from the first lateral plate 130
And/or the surface of the second lateral plate 140 is through to the holding tank, the gap is opened in the side of key bar 200.
After being accommodated in due to key bar 200 in the shank of the key 100, wrapped up completely by the shank of the key 100, in this case key
Producing for bar 200 is inconvenient, by opening up gap 170 in the shank of the key 100, so that the side of key bar 200 is exposed to open-minded
Mouth 170, so facilitates user and screws out key bar 200, there will not be sharp parts and expose the shank of the key 100.
As the supplement to above-mentioned technology, the shank of the key 100 offers multiple strip through-holes from top to holding tank 110
180。
Key after long-term use, can accumulate dirt unavoidably in holding tank 110, by opening up strip through-hole 180, be easy to hold
Receive the cleaning of groove 110；Furthermore if when key bar 200 is stuck in holding tank, strip through-hole can be passed through using strip instrument
Key bar 200 is disclosed holding tank 110 by 180.
In addition, the shank of the key surface is in rounding off shape；
The shank of the key material is plastics.
Plastic material grips comfortable, is rounding off state along with the shank of the key 100 is overall so that user avoid by
Because key is problem caused by metal that is hard and having sharp parts.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Based on explanation herein,
Those skilled in the art, which would not require any inventive effort, can associate other embodiments of the present utility model,
These modes are fallen within the scope of protection of the utility model.
