Abstract

The utility model discloses a key ring, comprises a ring, a key ring body is connected with the ring and provided with a cross bar, one end of a closed stop hook is in a hook-shaped structure capable of being sleeved on the cross bar, the other end is abutted against the ring to form a ring shape, and a holddown device is arranged in a space being wrapped by the closed stop hook and the key ring body. In use, only the closed stop hook is extruded inwards, a gap of the closed ring is opened, so that the key ring can be drawn out, after the outside force disappears, the closed stop hook can be closely abutted against the ring by the holddown device depending the self elastic force. If the parts in the key ring needs to be replaced, the closed stop hook is drawn out firstly, the holddown device is drawn out, the corresponding parts can be replaced, due to easy dismounting, the holddown device with appropriate resilient coefficients can be selected according to the need, thus the key ring is conveniently used, moreover, no latch pin is needed to seal the holddown device, thereby the appearance is more smooth.

Description

A kind of key chain

Technical field

The utility model relates to a kind of key chain that is used for Coordinates key.

Background technology

Key chain is a kind of ornament that hangs on the key-ring, is used for being convenient for carrying with a plurality of key chain together.Existing key chain, general employing elastic device is linked up with arc and the sealing stop hook is close to and be linked to be a complete closed circular, key chain just can hang on the waistband and not come off like this, when needs take off when using key, impose pressing of inward direction to stop hook, closed circular beaten open a gap, so just it can be taken off from waistband.Existing elastic device is generally stage clip or torque spring, patent CN201097707Y discloses a kind of preparation method of key chain, it adopts torque spring to seal the sealing ring that is formed by arc hook and sealing stop hook automatically, when inside extruding, key chain can be taken off from waistband, when external force is cancelled, torque spring is bestowed a reaction force, the sealing stop hook just resets and becomes complete closed circular with the button figure, but its shortcoming is, causes torsion strength to cause hook to come off easily inadequately easily; Patent CN201097706Y discloses a kind of key chain that adopts stage clip as elastomeric element, its stage clip is fixed in the middle groove of key ring body, the elastic force that relies on stage clip to produce resets the folding button, it has and is connected firmly, advantage easy to use, but its shortcoming is, is fixed on the button owing to adopt latch will seal stop hook, thereby dismounting inconvenience, and the key chain surface also seems smooth inadequately.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of convenient disassembly, and the key chain of its smooth outer surface.

Key chain described in the utility model, comprise the key ring ring, in the key ring body cross bar is housed, sealing stop hook one end is for being sleeved on the hook formation on the cross bar, the other end is abutted against mutually with the key ring ring and constitutes ring-type, in the space that sealing stop hook and key ring body side surface hold hold down gag is housed.

The hold down gag of installing in the space that sealing stop hook and key ring body side surface hold is torque spring or stage clip, if hold down gag is a stage clip, then sealing has on the stop hook and can stage clip be pressed on groove in the key ring body with the groove of key ring body side surface, stage clip one end is resisted against in the groove of key ring body, and the other end is resisted against in the groove of sealing stop hook; If hold down gag is a torque spring, then torque spring one end is resisted against on the key ring body, and the other end is resisted against on the sealing stop hook.

Key chain described in the utility model, one end of its sealing stop hook is a hook formation, can be sleeved on the cross bar in the key ring body, and can dismantle as required or install, like this, when renewal part, need not to pay many work, thereby it is easy to use, abut against on the key ring ring owing to the elastic force that just relies on stage clip or torque spring will seal stop hook in addition, thereby can select the stage clip of different coefficient of elasticity just can reach the purpose of different groups of going into of adaptation and environment for use needs, meet individual requirements according to the needs of oneself, be fixed on the button owing to need not to adopt latch will seal stop hook in addition, thereby its outer surface seems smooth.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of key chain, comprise key ring ring 11, the end side surface that key ring body 1 is connected with key ring ring 11 is fluted 7, and cross bar 5 is housed in the key ring body 1, and sealing stop hook 2 one ends are for being sleeved on the hook formation 4 on the cross bar 5, the other end is abutted against mutually with key ring ring 11 and constitutes ring-type, sealing has on the stop hook 2 and can stage clip be pressed on groove 6 in the key ring body with the groove 7 of key ring body 1 side, and stage clip 3 one ends are resisted against in the groove 7, and the other end is resisted against in the groove 6.

As shown in Figure 4, being equipped with below the key ring body can be around the card post 13 of key ring body rotation, being with one on the card post 13 can be around the pedestal 14 of card post rotation, through hole 16 is arranged on the pedestal 14 and can on spoon ring support 17, offer the spoon circle hole 18 that at least one places for key-ring 19 by jack-post 15 and 17 flexible connections of spoon ring support.

During use, only need a sealing shelves hook 2 inwardly push, closed-loop is beaten to open a gap just key chain can be taken off, after external force was cancelled, stage clip 3 can rely on self generation elastic force will seal stop hook and abut against on the key ring ring.As shown in Figure 3, when needing to change the parts on the key chain, will seal stop hook 2 earlier and take off, take out the stage clip that places the both sides groove again, just replaceable corresponding parts are because easy accessibility, thereby can select the stage clip of suitable elasticity coefficient, thereby conveniently use according to the needs of oneself.

Hold down gag described in the utility model also can be torque spring, its structure is that cross bar 5 is housed in the key ring body 1, sealing stop hook 2 one ends are for being sleeved on the hook formation 4 on the cross bar 5, the other end is abutted against mutually with key ring ring 11 and constitutes ring-type, in the space that sealing stop hook 2 and key ring body 1 side hold torque spring 3 is housed.
