Description

Flexible Key structure with lid

Technical field:

The utility model is about Key structure, especially about a kind of key that spoon plate is not exposed by lid slidably.

Background technology:

General common lockset key, its structure are one to take for the user and to hold the shank of the key of usefulness, and are equipped with spoonful bar on this shank of the key one end, and this spoon bar other end is equipped with spoonful plate, and this spoon plate is provided with the double wedge that cooperates lockset lockhole shape.So the key of structure because of the double wedge on the spoon plate can be run into human body, and allows the user feel under the weather when collection; Easier and other thing tied up in knots, and allow the user when taking key, other article can be taken out of thereupon, and then the situation that drops, loses happens occasionally.

In order to improve above-mentioned shortcoming, a kind of box that folds key is promptly arranged, though this box key can be collected, very inconvenient on taking, and account for collection space.Another kind then is that the spoon bar is folded in the shank of the key, and make spoon plate near the shank of the key, though this kind structure can reduce the volume of key, but plate is still protruding is exposed at outside the shank of the key for spoon, still can allow the user feel under the weather, easier and other thing tied up in knots, and allow the user when taking key, other article can be taken out of thereupon, and then drop or lose situation and take place, and are very undesirable in the use.

For improving the above-mentioned various shortcomings of commonly using device construction, this case designer is to be engaged in lockset manufacturing experience for many years, and through the permanent research and experiment of making great efforts, development and Design goes out the utility model finally.

Summary of the invention:

The purpose of this utility model is to provide a kind of flexible Key structure with lid, solves key and collects with minimum space, and its spoon plate can not expose the technical problem of tangling with other thing.

Technical solution of the present invention is as follows:

A kind of flexible Key structure with lid comprises: the shank of the key, spoon bar and spoon plate is characterized in that: be equipped with an outward extending sleeve pipe on this shank of the key; This spoon bar is set in the sleeve pipe of the shank of the key, extended or the withdrawal sleeve pipe in; Be provided with a lid, be provided with in this lid with sleeve pipe and the shank of the key are complementary and run through through hole, this through hole of mat can make lid respectively fit be coated on the shank of the key and the spoon plate.

Described flexible Key structure with lid, it is characterized in that: this lid is provided with a groove on certain position, then is provided with the convex body with this groove fit on the shank of the key relevant position.

Described flexible Key structure with lid is characterized in that: offer a perforate on the sleeve pipe of this shank of the key, this spoon bar is provided with movable press button; When this spoon bar stretched out sleeve pipe to limit, this press button just can protrudingly be exposed in this perforate.

Described flexible Key structure with lid is characterized in that: be provided with at least on this spoon plate one with a spoon bar parallel protruding shaft of rib; This lid through-hole wall corresponding position be provided with the projection block, when this lid wrap is combined on spoon plate, this block and protruding shaft of rib one end against.

Described flexible Key structure with lid is characterized in that: the chain-hanging hole position of this shank of the key is evagination not; This lid corresponding position is provided with the breach that chain-hanging hole is appeared.

Described flexible Key structure with lid, it is characterized in that: the section of this sleeve pipe is polygon or circle.

The utility model has the advantages that: when the time without key, can be by the contraction of spoon bar in sleeve pipe, to realize minimum collection space, by lid the spoon plate is coated fully simultaneously and do not expose, neither can make the double wedge on spoon plate press against to such an extent that the people feels bad, can not tangle other thing again, cause the possibility of carrying inconvenience or causing the leakage of dropping of other object; Can protect double wedge not to be damaged in addition.

The specific embodiment:

For enabling that the utility model is made further understanding and understood,, be described in detail as follows now for embodiment and cooperate graphicly:

See also shown in Fig. 1,2,3, the utility model is provided with a shank of the key 10, take for the user and to hold usefulness, this the shank of the key 10 is provided with convex body 11 on certain position, and this shank of the key 10 is provided with an outward extending sleeve pipe 12, this sleeve pipe 12 is a hollow tube, and its section configuration can be polygon, circle (as shown in Figure 7) or other shape.This sleeve pipe 12 is provided with a perforate 121, and is coated with one mobilizable spoon of bar 20 in this sleeve pipe 12.This spoon bar 20 is provided with movable press button 23, when spoon bar 20 extend out to limit from sleeve pipe 12, this press button 23 just can protrudingly be exposed in the perforate 121 with the location, and the user can push on this press button 23, itself and perforate 121 are disengaged, can make in spoon bar 20 withdrawal sleeve pipes 12.This spoon bar 20 other ends are equipped with spoonful plate 21, this spoon plate 21 be provided with at least one with the parallel protruding shaft of rib 211 of spoon bar 20, and this spoon plate 21 is provided with the double wedge 212 that cooperates lockset lockhole shape.

The utility model is provided with a lid 30, and this lid 30 is provided with a through hole 31 that runs through lid 30, and the shape of these through hole 31 middle part shapes and sleeve pipe 12 is complementary, and the shape and the shank of the key 10 in the space 32 of these through hole 31 both sides match, and slip into for the shank of the key 10.This lid 30 with convex body 11 relative positions on be provided with a groove 33 that is open shape, can be chimeric mutually with the convex body 11 on the shank of the key to make lid 30 by groove 33, the unlikely the shank of the key 10 that skids off.This lid 30 also is provided with the block of a projection in the inwall corresponding position of through hole 31.

Please refer to shown in Fig. 4 A, 4B, the 4C, during use, earlier spoon bar 20 is moved to the shank of the key 10 directions, make in spoon bar 20 withdrawal sleeve pipes 12 (shown in Fig. 4 B), again lid 30 is moved to spoon plate 21 directions, in moving process, under lid 30 the guiding successively, can successfully overlap, move at last on spoon plate 21 and and coat wherein fully spoon plate 21 to spoon plate 12 by the shank of the key 10, sleeve pipe 12, spoon plate 21.When this lid 30 coats spoon during plate 21 fully, be arranged on one of protruding shaft of rib 211 on spoon plate and correct the block place that is resisted against through hole 31 inwall projectioies, to prevent that lid 30 is from 21 landings of spoon plate.When the user will make when turning the key in the lock, can be with the lid on spoon plate 21 30, back be pushed on the shank of the key 10 along sleeve pipe 12, and by the convex body on the shank of the key 10 11 chimeric on groove 33, and be fixed on (as shown in Figure 6) unlikely landing on the shank of the key 10, so, not only easy to use, and close in practicality.

Moreover, please refer to the another kind of structure of the utility model shown in Figure 7, the main distinction of it and the foregoing description is that the part of the chain-hanging hole 12 on this shank of the key 10 is not the end that protrudes from this shank of the key 10, and lid 30 is provided with a breach 34 at the position of corresponding chain-hanging hole 12, when lid 30 fixed packet overlayed on the shank of the key 10, this chain-hanging hole 12 just in time was in this breach 34 places, so neither hinders carrying of key, tangible again evagination part causes sense of discomfort or tangles other thing.Secondly the cross section of its sleeve pipe 12 is circular.
