Description
Technical field
The utility model relates to survey instrument field, particularly relates to a kind of tape measure automatically powered on.
Background technology
Tape measure is measuring tool conventional in daily life, and it is building and the indispensable instrument of finishing and family.Tape measure rollable comes to be because be equipped with spring inside tape measure, and when pulling out measurement length, actual is the length of elongating tape measure and spring, once measure complete, spring inside tape measure can shrink automatically, and tape measure also and then shrinks under the action of the spring, so tape measure can roll.Also have multi-functional tape measure at present, it needs to power on and could realize various function, but it powers on, mode relies on switch to start, and namely must press the button or switch just can power on, and uses inconvenience.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of tape measure automatically powered on, and is intended to the problem solving its power on operation inconvenience of existing tape measure.
The technical solution of the utility model is as follows:
A kind of tape measure automatically powered on, wherein, the tape head of described tape measure is electric-conductor, a circuit board is provided with in described tape measure, described circuit board is provided with the first conductive electrode and the second conductive electrode near the position of tape head, and described first conductive electrode is connected with tape head electric wire with the second conductive electrode.
The described tape measure automatically powered on, wherein, described circuit board is provided with MCU.
The described tape measure automatically powered on, wherein, described tape head is conducting metal part.
The described tape measure automatically powered on, wherein, described circuit board is electrically connected the display screen that is arranged on tape measure surface.
Beneficial effect: the utility model by arranging the first conductive electrode and the second conductive electrode on tape measure circuit board, and tape head is set to electric-conductor, thus power-off when tape is pulled out, tape reply time conduction, such circuit board realizes automatically entering park mode or measurement pattern, operation is very easy, and without user's Non-follow control.
Accompanying drawing explanation
Fig. 1 is the structural representation after a kind of tape measure preferred embodiment automatically powered on of the utility model is cut open.
Fig. 2 is the process flow diagram of a kind of tape measure control method preferred embodiment automatically powered on of the utility model.
Embodiment
The utility model provides a kind of tape measure automatically powered on, and for making the purpose of this utility model, technical scheme and effect clearly, clearly, further describes below to the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is the structural representation of a kind of tape measure preferred embodiment automatically powered on of the utility model, as shown in the figure, the tape of described tape measure 100 300 is electric-conductor, a circuit board 200 is provided with in described tape measure 100, described circuit board 200 is provided with the first conductive electrode 210 and the second conductive electrode 220 near the position of tape 300, and described first conductive electrode 210 is connected with tape 300 electric wire with the second conductive electrode 220.
Tape 300 be in shrink (reset) state of reply time, due to tape 300 return, so itself and the first conductive electrode 210 and the second conductive electrode conducting 220, therefore the first conductive electrode 210 and the second conductive electrode 220 conducting, now tape measure enters into park mode, is namely in not using state.When pulling tape, tape 300 is pulled to outside tape measure, the now electric connection of the first conductive electrode 210 and tape the 300, second conductive electrode 220 and tape 300 disconnects, so the electric connection of the first conductive electrode 210 and the second conductive electrode 220 disconnects, now activate tape measure, make tape measure enter into measurement pattern.Such user starts the measurement pattern of tape measure without the need to the mode by pressing certain switch or button, as long as pull-out tape, automatically can enter into measurement pattern, simplify operation, facilitate use.
Described circuit board 200 is provided with MCU, i.e. microprocessing unit (also known as single-chip microcomputer), it, when the first conductive electrode and the second conductive electrode conducting being detected, enters into park mode, and when the second conductive electrode and the second conductive electrode disconnect, then enter into measurement pattern.
Described tape 300 is conducting metal part, and its material is metal, such as copper, and effect is its electric action, with the first conductive electrode 210 and the second conductive electrode 220 conducting, is formed and is electrically connected.
Described circuit board 200 is electrically connected the display screen that is arranged on tape measure 100 surface.This circuit board can provide and calculate tape extension elongation, and by length display on a display screen.Described display screen is preferably E-ink display screen, and it has the advantages that consumption rate is low and refresh rate is fast, is more suitable for use scenes of the present utility model.
In addition, the length of measurement can be preserved, and add timestamp, and the length under then different time can being stabbed is depicted as curve, allows user directly view the measurement length variations situation of oneself.Certainly, when measuring, first can preset several ID, allowing user select the ID of oneself, then measure, the length variations situation of several different tested product can be preserved so simultaneously.
Based on above-mentioned tape measure, the utility model also provides a kind of tape measure control method automatically powered on as above, and as shown in Figure 2, it comprises step:
During the pull-out of S101, tape head, the electric connection of described first conductive electrode, tape head and the second conductive electrode disconnects, and active circuit plate, makes tape measure enter into measurement pattern;
When S102, tape head are replied, the electric connection conducting of described first conductive electrode, tape head and the second conductive electrode, makes tape measure enter into park mode.
Further, described circuit board is provided with MCU.
Further, described tape head is conducting metal part.
In sum, the utility model by arranging the first conductive electrode and the second conductive electrode on tape measure circuit board, and tape head is set to electric-conductor, thus power-off when tape is pulled out, tape reply time conduction, such circuit board realizes automatically entering park mode or measurement pattern, operation is very easy, and without user's Non-follow control.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection domain that all should belong to the utility model claims.
