Description

A kind of level measuring rule with self-lighting function
Technical field
The utility model relates to field of measuring technique, particularly relates to a kind of level measuring rule with self-lighting function.
Background technology
Measurement of the level under dark surrounds needs to use lighting device to provide visual environment for spirit-leveling instrument reading, uses the mode of the outdoor head lamp of binding to provide visual environment or the special staff handheld illuminating device that is equipped with to provide illumination in current actual job more.In two kinds of lighting systems, the illuminating effect of front a kind of lighting system is not so good, and not only intensity of illumination is inconsistent up and down, and slight rocking also can cause illumination unevenness, causes instrument reading efficiency low; And turning in the process of station, the head lamp of binding often causes illumination abnormal because the reasons such as vibrations cause original strap-on structure to change, and often needs artificial righting, extremely bothers; In addition because head lamp energy consumption is large, the working time is short, often changes head lamp and extremely bothers.Then there is the defects such as light is uneven, energy consumption is bigger than normal, the working time is short in lighting system equally, but also will take an artificial handheld illuminating device more, exacerbates the anxiety of labour.
Therefore, a kind of energy consumption is low, continuous working period length, uniform light, novel lighting apparatus easy to carry, becomes the problem urgently studied in the industry.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provides a kind of level measuring rule with self-lighting function, makes it have that energy consumption is low, continuous working period length, uniform light, feature easy to carry.
A kind of level measuring rule with self-lighting function that the utility model provides, comprise level measuring rule, described measurement of the level related scale side is provided with the LED lamp bar of arranging along level measuring rule length direction, and described LED lamp bar shadow surface is towards the bar code on measurement of the level related scale.
In technique scheme, described measurement of the level related scale side is provided with the fixed strip arranged along level measuring rule length direction, be provided with the pickup groove matched with fixed strip bottom described LED lamp bar, described pickup groove is connected with fixed strip with measurement of the level related scale respectively.
In technique scheme, described fixed strip upper and lower surface is connected with pickup groove with measurement of the level related scale respectively by layers of two-sided.
In technique scheme, described LED lamp bar is provided with the aluminum alloy trough bar that is in the light that xsect is 1/4 circle, the described aluminum alloy trough bar that is in the light to be arranged at outside LED lamp bar and cambered surface evagination, the bottom surface that the plane that described LED lamp bar two is at right angles arranged is respectively shadow surface and is connected with measurement of the level related scale.
In technique scheme, described fixed strip has 3, arranges successively, the pickup groove of described LED lamp bar and fixed strip one_to_one corresponding along level measuring rule length direction.
In technique scheme, described LED lamp bar has two, is located at respectively on level measuring rule two sides.
The utility model has the level measuring rule of self-lighting function, has following beneficial effect:
One, the problems such as the illuminating ray of existing simple and easy lighting device is uneven, and instrument reading speed is partially slow are solved.
Two, the measurement of the level of this photograph is from the sustainable longevity of service of lighting device, sustainable work more than 7 hours, changes battery easy, and switch lamp is convenient.
Three, install simple and easy, good stability.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model has the level measuring rule of self-lighting function.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
See Fig. 1, the utility model has the level measuring rule of self-lighting function, comprises level measuring rule 1, two LED lamp bar 2,6 fixed strips 3 and the aluminum alloy trough bar 4 that is in the light.
Side, described level measuring rule 1 chi face is provided with the LED lamp bar 2 of arranging along level measuring rule 1 length direction, and described LED lamp bar 2 has two, is located at respectively on level measuring rule 1 two sides.Described LED lamp bar 2 shadow surface towards the bar code on level measuring rule 1 chi face, the long 1.8m of each LED lamp bar 2, wide 2cm.One end of described LED lamp bar 2 is connected with lithium battery (not shown) by power lead (not shown).
Side, described level measuring rule 1 chi face is provided with the fixed strip 3 arranged along level measuring rule 1 length direction, the pickup groove matched with fixed strip 3 is provided with bottom described LED lamp bar 2, described pickup groove is connected with fixed strip 3 with level measuring rule 1 chi face respectively, and described fixed strip 3 is soft magnet.Described fixed strip 3 upper and lower surface is connected with pickup groove with level measuring rule 1 chi face respectively by layers of two-sided (not shown).Each chi face of described level measuring rule 1 is provided with 3 fixed strips 3, arranges successively, the pickup groove of described LED lamp bar 2 and fixed strip 3 one_to_one corresponding along level measuring rule 1 length direction.
Described LED lamp bar 2 is provided with the aluminum alloy trough bar 4 that is in the light that xsect is 1/4 circle, the described aluminum alloy trough bar 4 that is in the light to be arranged at outside LED lamp bar 2 and cambered surface evagination, it is in order to optically focused that the aluminum alloy trough bar 4 that is in the light is arranged to this shape, even if the light that LED light source sends concentrates on the bar code on level measuring rule 1 chi face, show clearer.The bottom surface that the plane that described LED lamp bar 2 two is at right angles arranged is respectively shadow surface and is connected with level measuring rule 1 chi face.
In installation process, according to the length of LED lamp bar 2, by three double faced adhesive tapes along the equidistant bonding of level measuring rule 1 length direction on LED lamp bar 2 chi face, then fixed strip 3 correspondence is binded on level measuring rule 1 chi left side of face or right side, then just can LED lamp bar 2 be adsorbed on chi face, shadow surface is in the face of bar code, power lead one end is connected LED lamp bar 2, the other end connects lithium battery, in the coat pocket that lithium battery can be positioned over survey crew or the kit carried with, also the back side of level measuring rule 1 can be fixed on, open switch can normally work, operation is convenient.
The utility model have employed two high-quality LED lamp bar 2, and the illuminating ray sent is evenly sufficient, solves uneven, the unstable and problem that instrument reading speed that is that cause is slow of the light illumination that existing lighting device provides, significantly improves operating efficiency.This novel employing fixed strip 3 inhale and assembling mode, easily assembled, be convenient to dismounting and transport.Adopt the external power supply power supply mode being easy to change battery, and LED lamp bar 2 low energy, lithium battery electric capacity is large and can carry out charging and reuse, so the utility model has sustainable longevity of service, the easy feature of battery altering, is applicable to field work and uses very much.
