Abstract
A digital levelling rod with lighting device is composed of an indium tile rule with a lithium battery set fixed to its top, L ED lamp band near the front measuring region of said indium tile rule, iron sheets fixed to upper and lower parts of L ED lamp band, upper and lower magnets on said indium tile rule, L ED lamp band attracted to said indium tile rule by magnetic force, L ED lamps on its back, and dual-open control switches on said indium tile rule, which are connected between power lines of L ED lamp band on front of indium tile rule and L ED lamp near leveling bubble on back of indium tile rule via said dual-open control switches and COM interface of battery set.
Description
The technical field is as follows:
the utility model relates to a carry out the level construction at underground works such as tunnel, subway, mine, water conservancy or night and measure and subside the observed quantity time measuring, the digital levelling staff who uses.
Background art:
at present, when leveling construction measurement and settlement observation measurement are carried out in underground engineering such as tunnels, subways, mines and water conservancy projects or at night, common lighting equipment such as manual handheld electric flashlights or iodine tungsten lamps is usually adopted, the common lighting equipment or lighting effect is poor, or the use is inconvenient, a specially-assigned person needs to be arranged for lighting, and the labor cost is high.
When the flashlight is held manually for lighting, the flashlight is easy to shake, the lighting position is difficult to accurately hold, the lighting spot is uneven, the measurement efficiency and precision are affected, the measured data is unqualified and reworked easily, and meanwhile, a specially-assigned person needs to perform lighting of the flashlight.
The iodine-tungsten lamp is used for illuminating underground engineering or night construction sites, the iodine-tungsten lamp is high in use frequency due to high brightness and large illumination range, a 220V alternating current power supply needs to be connected, the iodine-tungsten lamp can be used under the condition of alternating current, electricians need to cooperate, the safety coefficient is low, the iodine-tungsten lamp is limited by the alternating current power supply, the application range is small, and the iodine-tungsten lamp is not suitable for leveling line measurement in a large range.
The invention content is as follows:
the utility model aims to solve the technical problem that a give a light to even, reduce measuring error, the observation data is quick accurate, reduces repeated measuring's digital levelling rod that has lighting device.
The purpose is achieved through the indium tile ruler, the lithium battery pack is fixed to the top of the indium tile ruler, a longitudinal L ED lamp belt is installed near a front measuring area of the indium tile ruler, iron sheets are fixed to the upper portion and the lower portion of L ED lamp belts, an upper magnet and a lower magnet are fixed to the indium tile ruler at positions corresponding to the upper iron sheet and the lower iron sheet of L ED lamp belts, the L ED lamp belt is attracted to the indium tile ruler through magnetic force, L ED lamps are installed near leveling bubbles on the back of the indium tile ruler, a double-open control switch is further installed on the indium tile ruler, power lines of the L ED lamp belt on the front of the indium tile ruler and power lines of the L ED lamps near the leveling bubbles on the back of the indium tile ruler are connected with a power line COM interface of the lithium battery pack through the double-open control switch, one path of the double-open control switch controls the longitudinal L ED lamp belt on the front of the leveling ruler.
Two handles are fixed on the back of the indium tile ruler.
The utility model has the advantages that use the power output of lithium cell group, make the L ED lamp area of indium tile chi openly installed can illuminate the bar code of indium tile chi and let the instrument read data measurement, L ED lamp at indium tile chi back-mounted simultaneously is located near the air level bubble, realized that the indium tile chi openly back all can gain the illuminating effect simultaneously, it is accurate quick to make instrument measurement data, this device adopts L ED lamp illumination, it is chargeable with large capacity, L ED lamp illumination is executed light evenly, reduce measuring error, improve work efficiency, it is quick accurate to observe data, reduce repeated measuring time.
Description of the drawings:
fig. 1 is a schematic front view of the present invention;
fig. 2 is a schematic rear view of the present invention.
The specific implementation mode is as follows:
the present invention will be further explained with reference to fig. 1 and 2;
the device comprises a lithium battery pack 1, wherein the lithium battery pack is fixed on the top of an indium tile ruler 2, a longitudinal L ED lamp strip 3 is arranged near a front measuring area 4 of the indium tile ruler, iron sheets 5 are fixed on the upper portion and the lower portion of each L ED lamp strip, an upper magnet and a lower magnet are fixed on the indium tile ruler at the positions corresponding to the upper iron sheet and the lower iron sheet of a L ED lamp strip, the L ED lamp strip is attracted to the indium tile ruler through magnetic force, L ED lamps 7 are fixed near leveling bubbles 6 on the back of the indium tile ruler, a double-open control switch 8 is further arranged on the indium tile ruler, power wires 9 of the L ED lamp strip on the front of the indium tile ruler and L ED lamps near the leveling bubbles on the back of the indium tile ruler are connected with a power wire COM interface of the lithium battery pack through the double-open control switch, one path of the double-open control switch controls L ED lamp strip on the front.
Two handles 10 are fixed on the back of the indium tile ruler.
