Technical Field

The utility model relates to a measuring tool field, more specifically relates to an electronic standard ruler.

Background

At present, the operation and maintenance personnel of power supply department need the measuring personnel to use the ruler to measure the interval in the acceptance work of new equipment, consults the data of each item technical specification the inside again, just can judge whether there is potential safety hazards such as safe distance is not enough in the equipment, and current equipment acceptance monitoring mode, the precision is poor, inefficiency.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome among the above-mentioned prior art and examine the defect that the acceptance inspection precision is poor, inefficiency at equipment, provide an electronic standard ruler.

The utility model discloses a first purpose is for solving above-mentioned technical problem, the technical scheme of the utility model as follows:

an electric rule comprising: the device comprises a main shell, a display panel, a length scale, a control module and a micro motor;

the length ruler is arranged in the main shell, and a hole for the length ruler to stretch is arranged below the middle side surface of the main shell; a display panel is arranged on one side of the main shell and is electrically connected with a control module arranged in the main shell; the bottom of the inner side of the main shell is provided with a micro motor, the micro motor is electrically connected with the control module, and the micro motor is in driving connection with the length ruler.

The utility model discloses a display panel selects to set for the technical standard data that corresponds, and control module generates control signal and controls micro motor according to selected technical standard data and rotates, and micro motor drives the length chi and stretches out the length that corresponds, and survey crew compares according to the length of electronic standard chi and the safe distance of waiting to check equipment, judges directly perceivedly whether new assembly accords with technical specification length data.

Furthermore, the electric standard ruler also comprises a power supply module, and the power supply module supplies power to the display panel, the control module and the micro motor respectively.

Further, the display panel includes a liquid crystal display and buttons. The length selection corresponding to the technical specification length data can be visually and conveniently carried out through the liquid crystal display screen and the buttons.

Further, the size of the telescopic hole is matched with the size of the length ruler.

Further, the control module is a single chip microcomputer control chip. And a singlechip is adopted for control, so that the functions are reliable and the cost is low.

Further, the micro motor is a micro servo motor. The rotation distance can be accurately controlled by using the micro servo motor.

Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:

the utility model discloses a display panel carries out the direct selection to technical specification length and sets for, and control module rotates according to the technical specification length control micro motor who selects, and micro motor drive length chi stretches out corresponding length, treats the check and acceptance equipment through length chi visual detection, easy operation, and is efficient.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1, an electric standard ruler includes: the device comprises a main shell 1, a display panel 2, a length ruler 3, a control module 4 and a micro motor 5;

the length ruler 3 is arranged in the main shell 1, and a hole for stretching the length ruler 3 is arranged below the middle side surface of the main shell 1; a display panel 2 is arranged on one side of the main shell 1 and is electrically connected with a control module arranged in the main shell 1; the bottom of the inner side of the main shell body 1 is provided with a micro motor 5, the micro motor 5 is electrically connected with a control module 4, and the micro motor 5 is rotatably connected with the length ruler 3. The utility model discloses still be equipped with power module 6, power module supplies power for display panel 2, control module 4, micro motor 5 respectively. The control module 4 is preset with standard data in technical specifications.

In a specific embodiment, a single-chip microcomputer control chip may be used as the control module 4, for example, the single-chip microcomputer control chip may be a 51 single-chip microcomputer or a stm32 single-chip microcomputer, and the single-chip microcomputer is used for control, so that the function is reliable and the cost is low. The micro motor may use a micro servo motor, such as a MAXON servo motor, which can accurately control the rotation distance.

The display panel 2 of the present embodiment includes a liquid crystal display and buttons. The liquid crystal display screen can visually display the preset technical specification length data in the control module 4, and the corresponding length is directly selected through the button. It should be noted that the size of the telescopic hole is adapted to the size of the length scale 3. More specifically, the width of the telescopic hole is greater than the width of the length ruler 3, and the height of the telescopic hole is greater than the thickness of the length ruler 3. The length ruler 3 is convenient to stretch through the design that the size of the telescopic hole is matched with the size of the length ruler 3.

The utility model discloses a 2 selection of display panel are set for the technical specification length that corresponds, and control module 4 generates control signal and controls micro motor 5 and rotates according to selected technical specification length, and micro motor 5 drives length chi 3 and stretches out the length that corresponds, and the measuring staff compares according to the length that the length chi stretches out and the safe distance of waiting to check equipment, judges directly perceivedly whether new equipment accords with technical specification's length.
