The utility model with the project ensures the strength of the key handle, has the advantages of flexible open and close, labor saving, electricity saving and strong brightness and is suitable for keys for unlocking at night, such as the keys of anti-theft doors and automobiles.

Description

The key of band photophore

The utility model provides the articles for use that are applied to daily life field, specifically with the key of photophore.

The key of existing band photophore normally is located on the shank of the key, and promptly the shank of the key integral body is photophore, and key bar is set in the photophore, adorns a luminous tube on the key photophore, photophore housing internal battery.Usually photophore is made of two shells, and the pinching housing makes the switch contact light photophore.The switch that has is a lamp base contact switch, has plenty of with the clutch of spring contact-actuating switch.Exist shortcoming as follows:

1. to account for volume big for switch, operates dumb.

2. use the photophore housing as the shank of the key, intensity is low, easily corrupted.

3. the luminous tube luminous efficiency is low, and battery is short service time.

The purpose of this utility model provides a kind of key of novel band photophore, and the switching manipulation that overcomes existing band photophore key is dumb, and intensity is low and luminosity is low, battery short shortcoming in application life.It is flexible to make it switch, and luminous efficiency height and intensity are good.

Realize that the purpose of this utility model scheme is, establish photophore installing hole and hanging hole on the shank of the key of metal, photophore is set in the installing hole on the shank of the key, improves key intensity; On the photophore housing, thin film switch is installed, is increased the switch flexibility; Use the excitated type luminous tube, make the light emitting source luminous tube, reduce power consumption, increase brightness; Outside the luminous tube shell, plate reflector layer, to improve luminous intensity.

Band photophore key by the utility model scheme is made because key is the disjunctor annular, promptly be provided with photophore installing hole and hanging hole, thereby the intensity height is difficult for corrupted, and is easy to carry about with one; Owing to be provided with thin film switch on photophore, area occupied is little again, flexible operation, and the life-span is long, and adult is low; Owing to use the excitated type luminous tube, the luminous intensity height is saved electric energy again; Also owing on the luminous tube shell, plate reflector layer, and the light utilization efficiency height, brightness of illumination is big.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structure chart.

In Fig. 1, (1) is key body, key body (1) front end is key bar (1a), the rear end is connected with the shank of the key ring (1c), in the shank of the key ring (1c), be provided with photophore installing hole (1b), be connected with key-ring (1d) in the shank of the key ring (1c) rear end, on key-ring (1d), be provided with key hanging hole (1e), on the ring wall in the same way of the last key bar (1a) of the shank of the key ring (1c), be provided with luminous tube fairlead (1f), at the shank of the key ring (1c) fairlead (1f) luminous shell (4) is installed laterally together, luminous tube (4a) is installed in luminous shell (4), in the luminous tube side and the back be provided with reflector layer (4b), a battery lead of luminous tube (4a) (3a) end points is located at the bottom of battery in place ring (2a), another root lead-in wire links to each other with thin film switch (3), and thin film switch (3) is established switch leads (3b) and linked to each other with photophore housing (2) opposite side.

The utility model scheme can be made into the key of the band photophore of plurality of specifications, the especially anti-more suitable employing of key of forcing open the door.Because anti-forcing open the door in corridor, night, light was dark, and when opening the door, difficulty is looked for keyhole, and adopted band photophore key that illumination can be provided, and helped unblanking.Especially the key intensity height of this practical new departure is bright strong, power saving, and switch is laborsaving, and is portable flexibly, exotic shape.Bigger application prospect is arranged.

Claims (1)

1. be with the key of photophore, on key body (1), be provided with key bar (1a), be connected with key-ring (1d) at shank, establish hanging hole (1e) in the link, it is characterized in that: be provided with the shank of the key ring (1c) at key handle part, inner formation photophore installing hole (1b), photophore (2) is installed in photophore installing hole (1b), thin film switch (3) is housed on the photophore housing, position in the same way at the shank of the key ring (1c) front and key bar (1a) is provided with luminous tube fairlead (1f), luminous tube housing (4) is installed in the fairlead outside, and luminous tube (4a) is installed within it, is provided with reflector layer (4b) in luminous tube (4a) outside.
