Description
Technical field
The utility model is related to daily necessities fields, and in particular to a kind of key chain.
Background technology
Existing key is buckled with non-disconnectable enclosed construction, and the key-ring used at present is mostly cyclic structure, i.e., by one
The larger elastic wire spiral winding of intensity is made, when need by key ring to key chain or by key-ring from key
It when taking on key ring, generally requires to be broken into two with one's hands the collar extension of key-ring with larger strength, and holds after repeatedly plucking, hanging operation
Key-ring easily is deformed, influences normal use.
Existing key chain also has removable enclosed construction, mainly includes the annular solid of opening and closed annular body opening
Lock pin, the both ends of annular solid are respectively equipped with the front through hole passed through for lock pin and rear through-hole, the side that lock pin is made to close annular solid
Formula generally has following two：
The first is that external screw thread is formed in the end of lock pin, and rear through-hole is the screw hole being adapted to lock pin external screw thread, that is, is locked
Pin is connected through a screw thread with rear through-hole carrys out closed annular body；After second passes through front through hole and rear through-hole for lock pin, after exposing
Increase locking system on the lock pin of throughhole portions, lock pin just can not move after being locked up, so as to make lock pin closed annular body.
Using the key chain of first way, dismounting needs special tool to carry out, such as realizes lock pin by screwdriver
Dismounting, this mode is troublesome in poeration, and screw thread easily loosens when in use.Using the key chain of the second way, locking
Picking and placeing for key-ring can be interfered by selling the increased locking system in exposed one end, be made troubles to the use of key chain.
Utility model content
The purpose of this utility model is to provide a kind of key chains easy to use, rational in infrastructure.
To achieve the above object, the utility model uses following technical scheme：
A kind of key chain, the hanging rod of key Button Block and the closing key Button Block including annular opening：
One end of the key Button Block is formed with the first through hole worn for the hanging rod, and the other end is formed with and described the
One through-hole is opposite and for the second through-hole that the hanging rod is worn, and the hole wall of second through-hole is equipped with mounting groove, the installation
Telescopic locating part is equipped in slot.
One end of the hanging rod is equipped with limiting slot close to end position, and the limiting slot is matched with the locating part, with
The hanging rod is limited in second through-hole by realization.
Preferably, the locating part includes elastic component and ball, described elastic component one end and the ball are affixed, another
The mounting groove slot bottom is fixed at end, and the ball is connected under the elastic reaction of the elastic component in the limiting slot, from
And it realizes and the hanging rod is limited in the second through-hole.
Preferably, the one end of the hanging rod far from the limiting slot, which forms one, limits its limit for passing through the first through hole
Position portion.
Preferably, one and the matched limiting block edge of the limiting section are formed in the first through hole.
Preferably, the limiting slot is along the circumferentially disposed annular groove of the hanging rod.
Preferably, the axial cross section of the limiting slot is arc-shaped.
Preferably, the first through hole and the second through-hole are circular hole, the hanging rod is cylinder.
Preferably, the elastic component is spring.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：
The hanging rod of the utility model will not interfere picking and placeing for key-ring, hang without realizing locking by specialist tools
After bar sequentially passes through first through hole and the second through-hole, by elastic component and ball by hanging rod locking, when needing to remove hanging rod, only need to use
The tip of pen tip etc slightly at full tilt releases hanging rod from the second through-hole, easy to use.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
It should be noted that term " on " " under " " left side " " right side " " vertical " " level " " interior " " outer " etc. in the utility model

Embodiment
Refering to what is shown in Fig. 1, the utility model discloses a kind of key chain, key Button Block 1 and closing including annular opening
The hanging rod 2 of key Button Block 1：
Coordinate shown in Fig. 1 and Fig. 2, one end of key Button Block 1 is formed with the first through hole 11 worn for hanging rod 2, the other end
The second through-hole 12 opposite with first through hole 11 and that hanging rod 2 is supplied to wear is formed with, 11 and second through-hole 12 of first through hole is circle
Hole, hanging rod 2 are cylinder, and the hole wall of the second through-hole 12 is equipped with mounting groove 13, telescopic locating part is equipped in mounting groove 13
14.Locating part includes elastic component 141 and ball 142, and in the present embodiment, elastic component 141 is spring.141 one end of elastic component with
Ball 142 is affixed, and the other end is fixed on 13 slot bottom of mounting groove, and when elastic component 141 is not squeezed by external force, 142 part of ball is exposed
In the second through-hole 12.
Coordinate Fig. 1 to Fig. 3 shown in, 2 one end of hanging rod close to end position be equipped with limiting slot 21, the limiting slot 21 with it is described
Locating part 14 matches, and hanging rod 2 is limited in the second through-hole 12 with realizing, limiting slot 21 is along the circumferentially disposed ring of hanging rod 2
Connected in star, the axial cross section of limiting slot 21 are arc-shaped.The one end of hanging rod 2 far from limiting slot 21 forms restricted its and passes through first to lead to
The limiting section 22 in hole 11.One is formed in first through hole 11 with 22 matched limiting block of limiting section along 111.
During using key chain, hanging rod 2 is first passed through into first through hole 11 and makes the end of hanging rod 2 close to the second through-hole 12, after
The second through-hole 12 is pushed into key ring upper hanging rod 2, then by the hanging rod 2 for hanging up key-ring.Hanging rod 2 is pushed into the second through-hole 12
When, the end of hanging rod 2 squeezes ball 142, and ball 142 is made to retract toward the direction of mounting groove 13, and hanging rod 2 is pushed further into, until hanging
The limiting slot 21 of bar 2 passes through mounting groove 13, at this point, ball 142 returns to initial position under the restoring force effect of spring, due to rolling
Part is exposed in the second through-hole 12 when pearl 142 is in initial position, and ball 142, which returns to, just limits hanging rod 2 after initial position
It is mobile, and then hanging rod 2 closes the key Button Block 1 of annular opening.
When needing to hang up key-ring or remove key-ring, the tip of pen tip etc need to be only used slightly at full tilt by hanging rod
2 release from the second through-hole 12, you can hang up or remove key-ring.
The preferable specific embodiment of the above, only the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, can be readily occurred in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
