Abstract
The utility model relates to a kind of dip stick, comprise a ruler, it is characterized in that described ruler is in long trihedral, its xsect is isosceles triangle, it is inner in hollow, be set with one identical with its shape, the interior chi that size is less, the inner top, side of described ruler is also provided with linear electric motors, located by pin and ruler bottom described linear electric motors, the telescopic end of described linear electric motors is located mutually by the top ends of pin with interior chi, described ruler inside is also provided with chargeable lithium cell, the voltage output end of described chargeable lithium cell is by being electrically connected with linear electric motors by compressing switch.When not used time at ordinary times, linear electric motors are in retracted state, and interior chi is retracted in ruler inside, convenient carrying at ordinary times, when measuring long object, can open the extended position by compressing switch, make linear electric motors protruding, in driving, chi stretches out, and makes ruler elongated, just can to measure comparatively long materials, when not measuring use, the advanced position by compressing switch can be closed, interior chi is bounced back, conveniently again carry.
Description
Technical field
The utility model relates to a kind of dip stick, especially relates to a kind of shrinkage-rule.
Background technology
Chi is used to a kind of instrument measuring object length, need sometimes to measure length with long hard chi, existing dip stick has and rolls volume pattern, but dip stick brings inconvenience very at work like this, special and when measuring object height, can cannot securing shortcoming, but to carry and inconvenient if ruler is directly made very long shape, and the utility model well solves existingly exists technical matters.
Summary of the invention
The utility model provides a kind of shrinkage-rule, and it mainly solves the shortcoming that existing dip stick uses the inconvenience of carrying very.
A kind of shrinkage-rule of the present utility model, comprise a ruler, it is characterized in that described ruler is in long trihedral, its xsect is isosceles triangle, it is inner in hollow, be set with one identical with its shape, the interior chi that size is less, the inner top, side of described ruler is also provided with linear electric motors, located by pin and ruler bottom described linear electric motors, the telescopic end of described linear electric motors is located mutually by the top ends of pin with interior chi, described ruler inside is also provided with chargeable lithium cell, the voltage output end of described chargeable lithium cell is by being electrically connected with linear electric motors by compressing switch.
As preferably: described by compressing switch as falling along by compressing switch.
The utility model provides a kind of shrinkage-rule, and when not used time at ordinary times, linear electric motors are in retracted state, interior chi is retracted in ruler inside, convenient carrying, when measuring long object at ordinary times, can opening the extended position by compressing switch, making linear electric motors protruding, in driving, chi stretches out, make ruler elongated, just can measuring comparatively long materials, when not measuring use, the advanced position by compressing switch can being closed, interior chi is bounced back, conveniently again carries.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Mark in figure: 1-ruler: chi in 2-: 3-linear electric motors: 4-pin: 5-chargeable lithium cell: 6-is by compressing switch.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, and by reference to the accompanying drawings the technical solution of the utility model being described in further detail.
Embodiment: as shown in Figure 1, a kind of shrinkage-rule of this example, comprise a ruler (1), it is characterized in that described ruler (1) is in long trihedral, its xsect is isosceles triangle, it is inner in hollow, be set with one identical with its shape, the interior chi (2) that size is less, described top, ruler (1) inner side is also provided with a linear electric motors (3), described linear electric motors (3) bottom is located by pin (4) and ruler (1), described linear electric motors (3) telescopic end is located with interior chi (2) top ends mutually by pin (4), described ruler (1) inside is also provided with chargeable lithium cell (5), the voltage output end of described chargeable lithium cell (5) is by being electrically connected with linear electric motors (3) by compress switch (6), described is suitable by compressing switch for falling by compress switch (6).When not used time at ordinary times, linear electric motors are in retracted state, and interior chi is retracted in ruler inside, convenient carrying at ordinary times, when measuring long object, can open the extended position by compressing switch, make linear electric motors protruding, in driving, chi stretches out, and makes ruler elongated, just can to measure comparatively long materials, when not measuring use, the advanced position by compressing switch can be closed, interior chi is bounced back, conveniently again carry.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
Claims (2)
