Embodiment one：As shown in Fig. 2 a kind of key chain, including U-shaped body 1, the body of rod 2, the first latch 3, the second latch 4
With compression spring 5.
As shown in figure 3, the both wings of U-shaped body 1 are provided with coaxial via 11.
As shown in figure 4, the body of rod 2 is circular hollow tube, the hollow cavity of hollow pipe is the through hole 21 of the body of rod 2, the one of through hole 21
End is provided with radially inner annular boss 22.
For first latch 3 by pressing, the mode for being either interference fitted or bonding is fixedly connected on the another of through hole 21
End.
As shown in Fig. 5 and Fig. 2, the second latch 4 is multi-diameter shaft shape, and compression spring 5 is located in through hole 21, compression spring 5
One end is against on the first latch 3, and the other end of compression spring 5 is against on the second latch 4, under the thrusting action of compression spring 5
Cascaded surface of second latch 4 away from the first latch 3 and the second latch 4 is stuck on annular boss 22.
The first latch 3 and the second latch 4 expose to the body of rod 2 and respectively the two of insertion U-shaped body 1 under without external force state
Individual via 11, the second latch 4 of compressing overcome the elastic force of compression spring 5 that the second latch 4 can be made to slide in retraction through hole 21.
The second latch 4 in the present embodiment is connected with the body of rod 2 for slip and un-emersion, and simple in construction, cost is cheap.
The latch 3 of via 11 and first, the second latch 4 in the present embodiment leave certain radial clearance.
When mounted, first the first latch 3 is inserted in a via 11, then oppressing the second latch 4 makes it slide retraction
In through hole 21, the second latch 4 is then directed at another via 11, unclamps the second latch 4, the second latch 4 is in compression spring 5
Another via 11 is automatically inserted under elastic force effect, that is, completes the connection of U-shaped body 1 and the body of rod 2.
When needing dismounting, it is slided in retraction through hole 21 with hard shaft the second latch 4 of compressing and depart from via
11 can remove the body of rod 2.
Instrument can not be needed during the key chain installation of the present embodiment, do not needed specific purpose tool during dismounting, facilitated user
Use.Other the present embodiment thoroughly solves the problems such as stripped thread is occurred, is loosened using screw connection in the prior art, significantly
Strengthen the safety and stability of key chain.
Embodiment two：The present embodiment and the difference of embodiment one are, as shown in fig. 6, also including two circular sets
Pipe 6 and two contact pins 7.
As shown in fig. 7, there is no annular boss in the through hole 21 of the body of rod 2 of the present embodiment, but in the both ends side wall of the body of rod 2
The waist-shaped hole 23 of two length directions is respectively equipped with, two waist-shaped holes 23 often held are arranged symmetrically with respect to the axle center of the body of rod 2.
As shown in Figure 8 and Figure 9, first latch 3 of the present embodiment and the second latch 4 are all cylinders, but are inserted first
Pin 3 is provided with radial direction jack 31, and the second latch 4 is provided with radial direction jack 41.
Again as shown in fig. 6, two contact pins 7 are closely plugged in two jacks respectively, the both ends of contact pin 7 are each passed through the body of rod 2
On waist-shaped hole 23 after expose to the body of rod 2, two sleeve pipes 6 are enclosed on the outside of the body of rod 2 and slide and rotate relative to the body of rod 2.
As shown in Figure 10, the inwall of sleeve pipe 6 is provided with two L-shaped stopper slots being evenly arranged around the axle center of sleeve pipe 6, and L-shaped is spacing
Groove includes axial groove section 61 and circumferential slot section 62.
Sleeve pipe 6 along the body of rod 2 slide and rotate when the both ends of contact pin 7 can enter circumferential slot section 62 respectively along axial groove section 61
Interior, the first latch 3 and the second latch 4 can slide along the through hole 21 of the body of rod 2, and the first latch 3 and the second latch 4 are along through hole 21
The body of rod 2 can be exposed to so that retraction through hole 21 is inner and outer during slip, the first latch 3 and the second latch 4 insert respectively when exposing to the body of rod 2
Two vias 11 of U-shaped body 1.
The present embodiment is slided using the circumferential slot section 62 of sleeve pipe 6 when being dismounted to stick contact pin 7 in waist-shaped hole 23,
The first latch 3 and the opposing through-bores 21 of the second latch 4 can be driven to slide, and cause first because waist-shaped hole 23 limits contact pin 7
The latch 4 of latch 3 and second can not depart from the body of rod 2.
When that need not be dismounted, contact pin 7 is skidded off from the L-shaped stopper slot of sleeve pipe 6, sleeve pipe 6 then on the body of rod 2 from
By moving, sleeve pipe 6 moves freely contact pin 7 under state and slips into from axial groove section 61 and driven into circumferential slot section 62 and sleeve 6
And the probability slided is minimum, the body of rod 2 can be avoided to depart from U-shaped body 1 due to accident.
The installation and removal of the present embodiment can not have to any instrument, and operation is easier, while thoroughly solve yet
The problems such as stripped thread occurs, loosens using screw connection in the prior art, the safety and stability of key chain is greatly reinforced.
Two specific embodiments of the present utility model are these are only, but design concept of the present utility model is not limited to
This, all insubstantial modifications made using the utility model design to the utility model, each falls within protection of the present utility model
Within the scope of.
