Abstract
The utility model discloses a key snap-ring, aiming to solve the problem that the prior key snap-ring is discommodious to hang and take keys. The key snap-ring comprises a round snap board, and a ring groove which is arranged at the external circumference of the round snap board. The ring groove is made with blind pores on the round snap board; a spring is arranged at the bottom of the blind pore, and a pin is matched with an opening close to the blind pore; and a through hole is arranged at the middle of the pin. A groove is made at the pin which is close to the opening end of the blind pore; one side of the round snap board is provided with an elongated hole which is parallel and communicated with the blind pore; and a round switch board is arranged at the end of the round snap board which is provided with the elongated hole; a rod like heave is arranged at one side of the round switch board which is close to the round snap board. The rod like heave after passing through the elongated hole of the round snap board is inserted in the through hole which is arranged at the middle of the pin, and joined with the pin; when the rod like heave is positioned at the top of the elongated hole of the round snap board, the groove at the end of the pin is commutated with the groove which is arranged at the external circumference of the round snap board.

Description
Technical field:
What the utility model related to small hangings such as a kind of wearing key articulates fastener, particularly a kind of key chain.
Background technology:
Key chain is mainly used in small hangings such as wearing key, and its major function is that small hangings such as a key concentrate in together, and is convenient to daily use; But also do not have a kind of extension on the market now, get the more convenient key chain of key.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of extension is provided, gets the more convenient key chain of key.
For achieving the above object, the utility model adopts following technical scheme: this key chain comprises circular buckle, outer peripheral edges along circular buckle are shaped on cannelure in circular buckle, the cross section of cannelure is rounded, and the opening of cannelure on circular buckle outer peripheral edges is less than the circular cross section diameter of cannelure; The spheric end cunning of key-ring bar is assigned in the cannelure of circular buckle, the cannelure of crossing circular buckle outer peripheral edges is shaped on blind hole to the diametric(al) of circular buckle, nearly bottom is placed with spring and is equipped with bearing pin at the nearly peristome of blind hole in blind hole, bearing pin is shaped on through hole radially in the stage casing, and is shaped on and above-mentioned cannelure cross sectional shape, big or small identical groove at the nearly blind hole openend of bearing pin; Side at circular buckle offers the strip hole that parallels with blind hole and communicate with blind hole, a side that has the strip hole at circular buckle is provided with and the identical circular switchboard of circular buckle size, one side of circular switchboard subcircular buckle is shaped on shaft-like projection, shaft-like projection is inserted in the through hole in bearing pin stage casing after passing the bar hole of circular buckle, and is linked together with bearing pin; When spring supported bearing pin and makes shaft-like projection on the circular switchboard be in the bar hole topmost of round button plate, bearing pin communicated with cannelure on the circular buckle outer peripheral edges at the groove of nearly blind hole openend; When the spring pressurized, when the shaft-like projection on the circular switchboard was in the bar hole foot of round button plate, the fluting end of bearing pin was in below the cannelure bottom of circular buckle.
The key chain of said structure in use, first key hangs on the key clasp, then the spheric end of key-ring bar is placed on the fluting end of bearing pin, firmly depress bearing pin, the fluting end of bearing pin is in below the cannelure bottom of circular buckle, at last the spheric end of key-ring bar is arranged in the cannelure of circular buckle; At this moment, bearing pin comes back to original position under the support of spring, and the spheric end of key-ring bar can not be deviate from cannelure; When needs take out key, press down bearing pin, the fluting end of bearing pin is in below the cannelure bottom of circular buckle, can from the cannelure of circular buckle, take out the spheric end of key-ring bar, extracting position is at the blind hole opening part of cannelure; So this practicality newly has extension, gets key advantage easily.
Description of drawings:
Fig. 1 is the structural representation (cut-away view) of the utility model key chain
The specific embodiment:
As shown in Figure 1, the utility model key chain comprises circular buckle 1, outer peripheral edges along circular buckle 1 are shaped on cannelure 2 in circular buckle 1, the cross section of cannelure 2 is rounded, and the opening of cannelure 2 on circular buckle 1 outer peripheral edges is less than the circular cross section diameter of cannelure 2; The spheric end cunning of key-ring bar 3 is assigned in the cannelure 2 of circular buckle 1, the cannelure 2 of crossing circular buckle 1 outer peripheral edges is shaped on blind hole 4 to the diametric(al) of circular buckle 1, nearly bottom is placed with spring 5 and is equipped with bearing pin 6 at the nearly peristome of blind hole 4 in blind hole 4, bearing pin 6 is shaped on through hole 7 radially in the stage casing, and is shaped on and above-mentioned cannelure 2 cross sectional shapes, big or small identical groove 8 at the nearly blind hole openend of bearing pin 6; Side at circular buckle 1 offers the strip hole 9 that parallels and communicate with blind hole 4 with blind hole 4, a side that has strip hole 9 at circular buckle 1 is provided with and the identical circular switchboard 10 of circular buckle 1 size, one side of circular switchboard 10 subcircular buckles 1 is shaped on shaft-like protruding 11, insert in the through hole 7 in bearing pin 6 stage casings shaft-like protruding 11 bar hole 9 backs of passing circular buckle 1, and be linked together with bearing pin 6; Present embodiment is shaft-like protruding 11 to be shaped on screwed hole in the end, by screw bearing pin 6 is connected with shaft-like protruding 11, and has the hole 12 that communicates with blind hole 4 at the opposite side of circular buckle 1, is used to make things convenient for mounting screw; When spring 5 supported bearing pins 6 and makes shaft-like protruding 11 on the circular switchboard 10 be in bar hole 9 topmosts of circular buckle 1, bearing pin 6 communicated with cannelure 2 on circular buckle 1 outer peripheral edges at the groove 8 of nearly blind hole openend; When spring 5 pressurizeds, when shaft-like protruding 11 on the circular switchboard 10 was in bar hole 9 foots of circular buckle 1, the fluting end of bearing pin 6 was in below cannelure 2 bottoms of circular buckle 1.
