Abstract

The utility model relates to a key looseness preventer for a key of an automotive engine lock, which comprises a key box with a key hole. The key looseness preventer has the following characteristics that: the key box is provided with a seesaw type fastener which is positioned on the side of the key and is used to prevent the key from getting out, and the corresponding side of the upper part of the key is correspondingly provided with a notch matched with the seesaw type fastener. The fastener is a seesaw type bent fastener, the hook of the front end of the fastener can be extended into the rabbet of the upper side of the key box and is fastened with the notch of the key, and a middle rotary shaft is arranged in the shaft hole of the key box; and a restoring spring which can drive the fastener to automatically restore is arranged between the lower end of the fastener and the key box. The key looseness preventer can effectively prevent the key from getting out of the key box, so that a car owner can conveniently carry and store the key and enter by way of emergency unlocking to start the automotive engine when electric unlocking fails or a storage battery runs out of electricity.

Description

The key anti-loosing device of car engine lock key

Technical field

The utility model relates to a kind of key anti-loosing device of car engine lock key.

Background technology

Enter in the system at Hyundai Motor, have the release of key mechanical formula to enter, the distance type release enters and exempt from key induction release enters; In the start-up system of car engine, there are traditional key mechanical formula startup and the bonding electron formula in the up-to-date luxury car to start.Exempting from key induction release enters with bonding electron formula startup automatically controlled for all-electronin, comparatively human nature intellectuality, but require automatically controlled vigour part etc. very reliable, cost is also higher. therefore, can make the car owner who carries the engine unlock key exempt to draw key, exempt to plug key, enter with the distance type release, only need the knob on the push-jump lock core just can start engine, realize the hommization operation; And when the automatically controlled release of remote control was lost efficacy, the release of meet an urgent need of available again key so the anti-loose locking device of the key of car engine lock key is researched and developed, will have crucial meaning.

Summary of the invention

The utility model purpose is the key anti-loosing device that a kind of car engine lock key will be provided, this device can prevent effectively that automobile key breaks away from key case, thereby helping the car owner carries and deposits key, so that when automatically controlled release inefficacy or battery do not have electricity, emergent release enters and starts car engine.

The key anti-loosing device of car engine lock key of the present utility model, comprise key case subdivision with key hole, it is characterized in that: be mounted with on the key case be positioned at the key flanking part, be used to the moving seesaw-type fastener that prevents that key from deviating from, the corresponding side correspondence in key top is provided with the draw-in groove that matches with the moving seesaw-type fastener.Compared with prior art, advantage of the present utility model is: the one, adopt the buckle draw-in groove form that matches, and it is firm to lock, anti-loose effective; The 2nd, adopt back-moving spring to guarantee fastener return chucking, so it is simple structure is reasonable in design, easy to use.

The specific embodiment

The key anti-loosing device of car engine lock key of the present utility model, comprise key box 2 with key hole 1, it is characterized in that: be mounted with on the key box 2 be positioned at key 3 flanking parts, be used to the moving seesaw-type fastener 4 that prevents that key 3 from deviating from, the corresponding side correspondence in key 3 tops is provided with the draw-in groove 5 that matches with moving seesaw-type fastener 4.Above-mentioned fastener 4 turns the shape buckle for moving seesaw-type, and leading section grab can stretch into key case 2 upper lateral part notches on it, and blocks key 3 draw-in grooves 5,, the middle part rotating shaft is placed on key case 2 axis holes; Be provided with the back-moving spring 6 that can order about fastener 4 self-returns between bottom and the key case 2.

With reference to shown in Figure 3: when key 3 inserted key box 2, outwards put fastener 4 upper ends, and Key 3 inserts; After key 3 insertions put in place, fastener 4 bottoms were under the ordering about of back-moving spring 6, and the leading section grab snaps in key 3 draw-in grooves 5 on the fastener 4, and tightly fastens the draw-in groove 5 on key 3 tops, prevented key 3 disengagements; When extracting key 3, earlier make on the fastener 4 the leading section grab break away from draw-in groove 5 and can take out key 3 by fastener 4 bottoms.

The utility model is novel, and is reasonable in design, has bigger promotional value.
