Description

Double-safety key-ring

The utility model relates to a kind of key chain, particularly a kind of two-stage key button.

In existing key chain, for preventing that key chain from coming off, all be that elasticity with key chain itself is closed tightly opening part, though this kind insurance mode is effective in the ordinary course of things, but can not prevent that but key chain from coming off under unexpected situation, for example when the suffered external force of key chain can be opened the closure place of key chain just, key chain just might come off, the situation of key loss takes place, and brings a lot of troubles and inconvenience to the user.

Also having a kind of key chain is that the elastic force of utilization itself embeds opening in the groove, if will open this kind key chain, opening must be mentioned, and pulls out groove, rotates to an angle then and just can open.Though this key chain insurance degree is a kind of higher than last, and is cumbersome at manufacture view, and heavier, it is a kind of convenient that use is not gone up yet.

The purpose of this utility model just provides a kind of key chain with two-stage insurance, can stop the situation that key chain meets accident and comes off fully.

The technical solution of the utility model is achieved in that two-stage key button is made up of hook, elasticity moving plate, elastic top thick stick, spacing rivet, joystick, link.One end of hook bends to hook-type, and the other end bends to small circle ring.One end of elasticity moving plate fixedly is riveted together with the small circle ring end of linking up with after bending to hook-type, and the hook end of the other end dependence of elasticity moving plate self elastic force and hook is adjacent to, and prevents that key chain from coming off, and forms first order insurance.The fixing riveted joint of the last curved end of wide slightly end of elastic top thick stick and elasticity moving plate, through hole location on the controlled handle square sleeve of narrow slightly end, the elastic top thick stick can not at will be moved, the square sleeve of joystick is contained on the hook, below the through hole on the square sleeve, also be processed with a through hole on the hook, be used with the through hole of the square sleeve of joystick, joystick another part except that square sleeve is formed a ring in irregular shape with square sleeve after bending, the activity upper limit of joystick on hook determined that by the spacing rivet that is fixed on the hook lower limit is determined by the riveting portion of elasticity moving plate and hook.When joystick is static, promptly when upper limit position, the elastic top thick stick withstands on the hook by the through hole on the square sleeve of joystick, make the elasticity moving plate stiff, the joint place that is elasticity moving plate and hook can not be opened, prevent key chain coming off when being subjected to unexpected external force fully, formed second level insurance.To the moving joystick of lower plate the time, when the through hole on the square sleeve of joystick with after through hole on the hook aligns, by the dynamic elasticity moving plate, the elastic top thick stick is passed from the hole, open the joint place of elasticity moving plate and hook, key chain can be hung up or takes off at this moment.After loosing one's grip, joystick resets under the elastic force effect of elastic top thick stick.Link is to bend to " U " shape by two circle metal plates that link together to form, and the circle centre position of two circle metal plates and the small circle ring of hook are riveted together with the activity riveted way.

The utlity model has advantages such as simple in structure, esy to use, safe and reliable.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a kind of stereogram of existing key chain.

Fig. 2 is the three-dimensional cutaway view of two-stage key button embodiment.

Fig. 3 is the stereogram of the link of two-stage key button.

With reference to Fig. 1, this kind key chain is a kind of key chain that generally uses now, it is formed by the bending of a rubber-like strip foil, the arm of force that utilizes big end to form owing to bending length is little is little, the intensity height is as stationary end, promotion, can be closed under certain elastic force effect tightly so crooked rear port is in simultaneously because sheet metal itself has elasticity as the elasticity movable end.Need only firmly key chain can be opened gently during use, pick and place key, but because this key chain is only closed interface tightly by elastic force own, and there is not other insurance measure, so be easy to that the marquis is opened easily by external force when ignorant, cause losing of key, bring great trouble to the user.

With reference to Fig. 2, Fig. 3, the utility model is made up of hook (1), elasticity moving plate (2), elastic top thick stick (3), spacing rivet (4), joystick (5), link (6).One end of hook (1) bends to hook-type, and the other end bends to small circle ring.One end of elasticity moving plate (2) bends to hook-type, and fixedly is riveted together with the small circle ring end of linking up with (1), and the other end relies on the elasticity of self and the hook end of hook (1) to close tightly, forms first order insurance, prevents to come off.The fixing riveted joint of the wide slightly end of elastic top thick stick (3) and elasticity moving plate (2), the through hole location on the square sleeve of the controlled handle of narrow slightly end (5) is against on the hook (1), makes elasticity moving plate (2) stiff, forms second level insurance.Also there is a through hole through hole below at the square sleeve of joystick (5) on the hook (1), is used with through hole on the square sleeve of joystick (5), and elastic top thick stick (3) is passed.The remainder of joystick (5) except that square sleeve formed a ring in irregular shape with square sleeve after bending, as the origin of force that promotes joystick (5).Joystick (5) is gone up the movable upper limit at hook (1) and is determined that by the spacing rivet (4) that is fixed on the hook (1) lower limit is determined by the riveting portion of elasticity moving plate (2) and hook (1).Link (6) is to bend to " U " shape by two circle metal plates that connect together to form, and the small circle ring of the circle centre position of two circle metal plates and hook (1) is riveted together with the activity riveted way.Link (6) can be that axle rotates to an angle with the rivet.When using two-stage key button, promote joystick (5), make joystick (5) be displaced downwardly to the lower position, through hole on the square sleeve of joystick (5) aligns with the through hole of hook (1), from hole pass elastic top thick stick (3) by dynamic elasticity moving plate (2) this moment, loses insurance, elasticity moving plate (2) separates with the joint place of hook (1), and can pick and place key chain this moment.
