Description

The tape measure for using at night

Technical field

The utility model relates to a kind of tape measure, refer in particular to a kind of through improvement design, can night use the tape measure for using at night.

Background technology

Tape measure obtains general use in life, and common tape measure is not under having external light source to irradiate night, and clearly cannot observe scale, cause normally using, impact is measured.

Summary of the invention

The purpose of this utility model is: propose one and be combined with tape measure by paster LED, and the tape measure for using at night that normally can use at night.

The utility model is achieved through the following technical solutions:

A kind of the tape measure for using at night, comprises housing, and housing is provided with tape outlet, and be provided with tape in housing and return tape assembly, be also provided with contact and power supply in described housing, described hull outside is provided with the light source switch be slidably connected; Described power supply provides electric energy for whole circuit, and described power supply and contact and light source switch are electric connection, and described contact is located at the side of tape outlet, and described light source switch is located at tape outlet opposite side;

Described tape is translucent or transparent material, and described tape comprises tape A layer and tape B layer, is provided with layer of transparent conducting film A outside described tape A layer, is provided with layer of transparent conducting film B outside described tape B layer; The Chip-R being provided with paster LED between described tape A layer and tape B layer and matching with paster LED, described paster LED one end is electrically connected nesa coating A, the paster LED other end is electrically connected one end of Chip-R, and the other end of Chip-R is electrically connected nesa coating B.

In such scheme, described power supply is button cell.

In such scheme, described button cell is located in the groove of described enclosure interior.

In such scheme, described paster LED and Chip-R are evenly distributed in tape.

The beneficial effects of the utility model are:

(1) the utility model have employed novel paster LED, affects the thickness of tape hardly, after the Chip-R that matches that paster LED is connected, adds circuit stability, life-time dilatation easy to use; Simultaneously, the contact adopted and light source switch, all conductive, after pull-out tape, light source switch is promoted to contact, nesa coating, paster LED, Chip-R, contact and button cell then in light source switch, tape form closed-loop path, and paster LED is luminous, then realize the effect of visualization to tape high scale at night.

(2) the utility model is provided with some paster LEDs in tape, each paster LED is connected a Chip-R, be one with paster LED and Chip-R to combine, be in parallel between any two combinations, therefore when after closing of circuit, paster LED in whole piece tape all can be luminous, and therefore, whole piece tape presents visual effect.

In figure: 1-tape, 2-contact, 3-power supply, 4-light source switch, 5-groove, 6-paster LED, 7-Chip-R, 8-tape A layer, 9-tape B layer, 10-nesa coating A, 11-nesa coating B

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1 and Figure 2, a kind of the tape measure for using at night, comprises housing, housing is provided with tape outlet, is provided with tape 1 and returns tape assembly, be also provided with contact 2 and power supply 3 in described housing in housing, described hull outside is provided with the light source switch 4 be slidably connected, and contact 2 and light source switch 4 all can conduct electricity; Described power supply 3 provides electric energy for whole circuit, described power supply 3 is electric connection with contact 2 and light source switch 4, described contact 2 is located at the side of tape outlet, and described light source switch 4 is located at tape outlet opposite side, and described contact 2 and light source switch 4 are not directly electrically connected;

Power supply 3 have employed practical and that volume is little button cell, and button cell is located in the groove 5 of described enclosure interior.

Described tape 1 is translucent or transparent material, as shown in Figure 3, described tape 1 comprises tape A layer 8 and tape B layer 9, layer of transparent conducting film A10 is provided with outside described tape A layer 8, layer of transparent conducting film B11 is provided with outside described tape B layer 9, nesa coating A10 and nesa coating B11 isolates mutually, does not directly connect; The Chip-R 7 being provided with paster LED 6 between described tape A layer 8 and tape B layer 9 and matching with paster LED 6, described paster LED 6 one end is electrically connected nesa coating A10, paster LED 6 other end is electrically connected one end of Chip-R 7, and the other end of Chip-R 7 is electrically connected nesa coating B11.Described paster LED 6 and Chip-R 7 are evenly distributed in tape 1.

Therefore, tape 1 is hauled out from tape outlet, in the process again light source switch 4 promoted to contact 2, contact 2 and light source switch 4 touch different nesa coatings respectively, again by the connection of paster LED 6 between tape A layer 8 and tape B layer 9 and Chip-R 7, circuit forms closed-loop path, and paster LED can be luminous.

When using the utility model by day, be namely as good as with the normal tape measure of use, without the need to opening light source switch 4, hauling out tape 1 can measure; When using the utility model night, haul out after tape 1 and light source switch 4 is promoted to contact 2, until circuit closed, can measure at night, and clearly check measurement result.
