Description

Detachable electric tape measure

Technical field

The utility model relates to a kind of electric band tape, particularly a kind of detachable electric tape measure with electronic and manual driven in two modes.

Background technology

Tape measure is survey tool conventional in one way of life, conventional has metallic tape rule and nonmetallic flexible tape measure, metallic tape rule generally possesses the function of automatic retraction, the mode of the hand retraction of the many employings of common nonmetal tape measure, though existing electric band tape possesses electronic retraction function, but because motor is arranged on tape measure inside, make tape measure overall dimensions bigger than normal, carry very inconvenient, and waterproof effect is bad, ordinary tape measure is when measurement is greater than the object of its range, need first to mark, and then tape measure is regained next section of measurement again, this measuring method not only bothers but also measures inaccurate, there is very large error, and mark is difficult to there is fixing point sometimes, very difficult measurement.

Summary of the invention

The utility model main purpose is to solve the problem and not enough, provide a kind of motor to be separated with tape measure body, by motor Fast Installation and can pull down, and possesses the detachable electric tape measure that multiple tape measure combinationally uses.

For achieving the above object, the utility model have employed following technical scheme: a kind of detachable electric tape measure, comprise housing, be arranged on the rotating shaft of casing center, be wrapped in the tape in rotating shaft, be fixedly connected on the rocking handle of rotating shaft side, and be positioned at motor and the battery of opposite side, described motor and battery are fixed on one independently in box body, and box body and housing are releasable connection, and it is outer and be meshed with rotating shaft that the axle head of described motor extends to box body;

The front end of described tape is provided with a metal pull head, and described metal pull head has the flange that both direction up and down extends, and the working face of described tape is provided with spaced apart, can make the locating hole that metal pull head upper flange inserts.

Further, described box body and the releasable connection of housing are that magnetic is connected, the surface of described box body has at least three round boss, described housing has corresponding shrinkage pool to the one side that box body coordinates, described boss and shrinkage pool have contrary magnetic, when box body and housing near time, because magnetic is attracting, the boss of box body is inserted in the shrinkage pool of housing, plays location and fixing effect.

Further, the axle head of described motor is hexagon, and described rotating shaft is corresponding interior hexagon to the engagement place of motor, and when box body is fixed on housing, motor shaft is corresponding to be inserted in rotating shaft, and drive shaft is rotated.

Further again, the junction of described box body is provided with waterproof grommet, and box body possesses water-proof function.

Compared with prior art, the beneficial effects of the utility model are:

A kind of detachable electric tape measure described in the utility model, its motor and battery are independently arranged in the box body of waterproof, during use only need by box body and housing close, under the effect of magnetic force, box body will be fixed on housing automatically, realize motor and drive the function of retracting, therefore the small volume of tape measure, be convenient for carrying, and can use as manual tape measure after pulling down motor, the metal pull head of this tape measure can be inserted in the locating hole of another band tape, and multiple tape measure can combinationally use, and effectively improves the accuracy of measurement.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Embodiment of the present utility model is, shown in composition graphs 1, Fig. 2 and Fig. 3, a kind of detachable electric tape measure, comprises housing 1, is arranged on the rotating shaft 2 at housing 1 center, be wrapped in the tape 3 in rotating shaft 2, be fixedly connected on the rocking handle 4 of rotating shaft 2 side, and be positioned at motor 5 and the battery 6 of opposite side.Wherein, motor 5 and battery 6 are fixed on one independently in box body 7, and box body 7 and housing 1 are releasable connection, are preferably magnetic and connect, and also can adopt grab or other connected modes such as bonding, and it is outer and be meshed with rotating shaft 2 that the axle head of described motor 5 extends to box body 7.Be provided with a metal pull head 8 in the front end of tape 3, metal pull head 8 has the flange that both direction up and down extends, and wherein, upper flange area is less than lower flange.The working face of tape 3 is also provided with spaced apart, can makes the locating hole 9 that metal pull head 8 upper flange inserts, the size of locating hole 9 is close with upper flange or be slightly less than upper flange.

The concrete structure that described box body 7 is connected with the magnetic of housing 1 is, the surface of box body 7 has at least three round boss, and the one side that housing 1 coordinates to box body 7 has corresponding shrinkage pool, and boss and shrinkage pool are embedded with magnetic material, and has contrary magnetic.Therefore, when box body 7 and housing 1 near time, because magnetic material is mutually attracting, the boss of box body 7 is inserted in the shrinkage pool of housing 1, serves location and fixing effect.

The axle head of described motor 5 is hexagon, and described rotating shaft 2 and the engagement place of motor 5 are corresponding interior hexagon, and when box body 7 is fixed on housing 1, motor shaft is corresponding to be inserted in rotating shaft 2, and drive shaft 2 is rotated.

Shown in composition graphs 4, using method of the present utility model is: first, metal pull head 8 is pulled out from housing 1, and be hooked on measurement thing, pull-out tape 3 is measured, when larger by the size of amount thing, can the metal pull head 8 of another tape measure be inserted in the locating hole 9 of this band tape 3, two tape 3 are combined, pull on and put in row measurement, to survey actual size be two chi reading sums, after measurement completes, can hand rocking handle 4, tape 3 is retracted in housing 1, also motor 5 can be installed, after box body 7 fixes, motor shaft is connected with rotating shaft 2, and drive rotating shaft 2 to rotate, tape 3 is regained.When battery 6 adopts rechargeable battery, box body 7 can be pulled down, charge to battery 6, now tape measure still can manually use.
