Abstract

The invention discloses a novel portable flexible ruler with an additional laser illumination function. A shell of the flexible ruler is in an arch shape with two bottom corners. A laser head and a button cell are arranged in the spaces of the two bottom corners respectively. A micro switch is arranged at the position, close to the bottom corners, of the middle of the bottom side of the shell. The laser illumination function is added, but the original diameter of the shell of the flexible ruler is kept unchanged, the size of the shell is basically unchanged, portability of the flexible ruler is not influenced, and extremely-large practicability is achieved. The problem, carpenters, maintainers and variable technicians always want to solve but can hardly solve, that the laser illumination function can be added basically without increasing the size of the outer shell of the flexible ruler, is solved. The number of added elements is small, the cost is low, and therefore the cost performance is high.

Description

A kind of novel portable tape measure of realizing subsidiary laser

Technical field

The present invention relates to a kind of tape measure, especially can complete the tape measure of realizing subsidiary laser and substantially do not increase again shell sizes.

Background technology

At present, the application of tape measure is very extensive, and the widespread use of tape measure be unable to do without its small and exquisite volume property carried in pocket, and small and exquisite volume is one of people's major reason of carrying 5 meters of following tape measures, some carpenter master workers, no matter the spring, summer, autumn and winter, always carrying tape measure, even tie up to together with key on waistband, more convenient with tape measure, particularly run into what anxious living, size up at any time, can save a lot of time.In practice of construction, a lot of places need to be straight by looking between surperficial levelling concavo-convex height, 2, and people wish the tape measure of carrying always, not only can measuring distance, can also determine after distance range have and look for straight utility function by between surperficial levelling concavo-convex height and at 2.

" a kind of laser flexible rule " of notification number CN2798035Y finds it is the radial position at the dish tape strip of tape measure inside from accompanying drawing, No. 7 dry cells and horizontally set laser head are vertically set, and No. 7 dry cell diameter 10mm, the laser head length 10.5mm of market minimum, bend tape casing diameter will obviously increase like this, is unfavorable for tape measure carrying in pocket.

" a kind of novel buckle laser flexible rule " of publication No. CN103353266A, finds that from accompanying drawing laser head is arranged on chi bar and imports and exports top position, and laser head is horizontally installed on the radial position of the dish tape strip of tape measure inside, and bend tape casing diameter will obviously increase.

Such scheme ubiquity obviously increases the defect of bend tape casing diameter, because element is set in the radial position of the dish tape strip of tape measure inside, housing diameter will increase thereupon, has affected the property carried of tape measure, has limited application in practice.

Summary of the invention

Obviously to increase in order overcoming because setting up laser diode shell the deficiency that impact is carried, a kind of portable arch door shape tape measure that laser diode does not increase again bend tape casing diameter, substantially do not increase shell sizes of setting up to be provided.

To solve the technical scheme that its technical matters takes be: this tape measure of having set up laser diode and do not increase again housing diameter, its housing is arch door shape, arch door shape has two base angles, two base angles are respectively arranged with laser head and button cell in space, are provided with microswitch at middle part, housing bottom side near base angle place; Described laser head adopts the laser head of bis-kinds of diameter 6mm, length 10.5mm, operating voltage 3V or 4.5V, and described button cell is that CR2032 battery or three the AG10 button cells series windings of a 3V are 4.5V.

Laser has good directionality, the high characteristic of some shaped laser spot brightness, the red laser that red laser hair is penetrated runs into the redness point shaped laser spot that restraining mass produces, also can see clearly in bright light environments, as long as in the scope that can see clearly at a shaped laser spot, laser can be used as that datum line is straight by looking between 2 o'clock, near the surperficial levelling that make uniform in position, height is concavo-convex of object datum line.

Beneficial effect is, compared with prior art, the combination of the each technical characterictic after combination, has produced new technique effect: cleverly in the space, two base angles of arch door shape housing, respectively be provided with Red Beds In Small laser head and button cell, be provided with microswitch at middle part, housing bottom side near base angle place; Although set up laser function, keep original diameter of bend tape casing constant, shell sizes is substantially unchanged, does not affect the property carried of tape measure, has its very big practicality.Solve carpenter, upfitter and multiple technologies personnel and wished that solve and the insoluble bend tape casing size that substantially do not increase always, problem that can additional laser function.And increase that number of elements is few, cost is low, so cost performance is high.

Through test, in bright light environments, require some shaped laser spot can see clearly 8 meters of distances, flow through under the condition of electric current 20mA left and right of laser head, change one time common, inexpensive button cell, can use continuously 1 hour, general each Emission Lasers datum line 5 seconds, can meet in levelling, open and close service time once in looking for straight actual use, can Emission Lasers datum line 720 times.In construction, utilize the tape measure carried, determine after distance range, near the utility function requirement of the surperficial levelling that make uniform in position, height is concavo-convex of object, datum line straight by looking between 2 o'clock at any time.
