Abstract

A kind of key numbered, is made of key body, roller, transparent gum cover three parts.On the handle of key body, there is rectangular opening.There is transverse axis on rectangular opening.Installed on transverse axis with 090 digital five rollers lateral margin.On the lateral margin of digital roller, there is 0 to 90 numeral.Transverse axis constitutes turning gear with roller.Rotation roller, can be combined out any one digital number from 00000 to 99999, for identifying room number.Transparent gum cover is sleeved on handle, and first can play the role of anti-skidding, and second can fix roller, is prevented because roller rotates caused by friction.

Description

A kind of key numbered

Technical field

A kind of key numbered is the utility model is related to, for distinguishing the multiple keys of string together, in order to avoid trigger mixed Disorderly.

Background technology

Key loss in order to prevent, is the custom of many people by multiple key chains together.Used in multiple doors same In the case of model door lock, the shape of key is all substantially similar, and string is difficult to distinguish afterwards together.

Utility model content

In view of the above-mentioned problems, the utility model aims to provide a kind of technical solution.The numbering carried by key fills Put, to solve the above problems.

The utility model is made of key body, roller, transparent gum cover three parts（Fig. 1）.

Key body includes handle 0 and discloses bar 3 two, on key handle, there is keyhole 1 and rectangular opening 10.Rectangular opening On have transverse axis 11.The position of rectangle frame side face transverse axis, is useful for the positive identification point 12 of mark key.

At left and right sides of key handle, there are U-shaped groove 2 and U-shaped groove 4.The complete phase of shape of U-shaped groove 2 and U-shaped groove 4 Together.

Roller is using the plastics or colloid for possessing certain toughness.It is different according to room number, roller can have it is multiple, such as 2, 3,4,5 or more.The example of the utility model be 5 rolling wheel structures key, including roller 5, roller 6, roller 7, rolling Wheel 8, roller 9.

All rolling wheel structures are identical, are all circular middle with hole constructions.Roller side 13 is smooth construction, and there is the center of circle in centre Hole 14, there is numeral 15 on side, and numeral shares 10 from 0-9（Fig. 2）.

Have on roller from circle center hole to roller edge and run through groove 16, the groove width through groove is less than the diameter of transverse axis.Run through The effect of groove, is that roller is installed on transverse axis.

Because roller possesses certain toughness, therefore can moderately strut through groove, easy to which roller is installed on transverse axis.Will After roller is installed on transverse axis, because the toughness of roller, what is be softened restores to the original state through groove, its groove width is less than the straight of transverse axis Footpath, during rotation roller, roller will not just come off from transverse axis.

Roller is fixed on transverse axis, forms turning gear with transverse axis, roller can be rotated arbitrarily on transverse axis.

Rotation roller, the numeral on five roller lateral margins, can be combined into any one numeral from 00000 to 99999, use To represent room number.

Transparent gum cover 17 is oval tubular in normal state.After gum cover stretching, it is sleeved on key handle, imbeds handle In the U-shaped groove of both sides.

The effect of transparent adhesive tape set has two：First is anti-skidding, and gummed paper material is easier to hold than metal material, and feel is better than gold Belong to material；Second is fixed, and after gum cover is sleeved on handle, gum cover is shunk, and roller is clamped, and avoids roller because frictional rotation is led The key identification of cause is chaotic.

Transparent gum cover is sleeved in the U-shaped groove 2 and U-shaped groove 4 on key handle.Because the presence of groove, gum cover is not It can come off because of sliding up and down.

Brief description of the drawings

Fig. 1 is the structural map of the utility model.

Wherein：0 --- handle；1 --- keyhole；2 --- U-shaped groove；3 --- disclose bar；4 --- U-shaped groove； 5 --- roller；6 --- roller；7 --- roller；8 --- roller；9 --- roller；10 --- rectangular opening；11 --- transverse axis； 12 --- identification point；17 --- gum cover..

Fig. 2 is roller enlarged drawing.

Wherein：13 --- roller side；14 --- circular hole；15 --- numeral；16 --- through groove.

Embodiment

With reference to Fig. 1, specific embodiment of the present utility model is described below.

For having the building in multiple rooms, after room number is determined, start to determine key numbering.Such as a list , it is necessary to identify the key in its 32nd building No. 108 room, determine that key is numbered is building of the floor room number more than 100 32108。

Key is carried to the one side face operator of identification point 12, the numeral 3 of roller 5 is turned into face identification point 12 position, the position of face identification point 12 is turned to by the numeral 2 of roller 6, and the numeral 1 of roller 7 is turned to face mark The position of point 12, turns to the position of face identification point 12 by the numeral 0 of roller 8, the numeral 8 of roller 9 is turned to face mark Know the position of point 12.Numeral 32108 completes combination.

Transparent gum cover is stretched, is sleeved in the U-shaped groove location of handle.Gum cover is decontroled, gum cover is shunk, and roller is by glue Set is fixed, and will not be rotated because of touching or other reasons.

When reading key numbering, for key with identification point one side, a number of rows word of face identification point 12, is that key corresponds to Room number.

Claims

A kind of 1. key numbered, it is characterised in that：It is made of key body, roller, transparent gum cover three parts, key body Handle center have rectangle frame, have transverse axis in rectangle frame, lateral margin forms shaft with ten digital five rollers of 0-9 with transverse axis Device, rotation roller, can be combined out any one digital number from 00000 to 99999.
A kind of 2. key numbered according to claim 1, it is characterised in that：Have on roller from circle center hole to roller side Edge runs through groove, and the groove width through groove is less than the diameter of transverse axis.
