Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings.

A laser tape measure comprises: a casing 10; a tape measure 20, the tape measure 20 is disposed in the casing 10, and the tape measure 20 is stretched outside the casing; the push button 18, the push button 18 is disposed on the casing 10, and the push button 18 is provided. For releasing or stopping the expansion and contraction of the tape measure 20; a laser generator, the laser generator is disposed in the casing 10, the laser generator is used to emit the laser; the first level 16 and the second level 17, the first level 16 and the second level 17 Provided on the casing 10, the first level 16 and the second level 17 are used to detect whether the laser tape is placed flat.

The first level 16 is a lateral blisters, and the second level 17 is a longitudinal blisters, and it is judged whether the plane of the laser tape measure is flat according to the position of the blisters in the level.

Further, a button 15 is further included, and the button 15 is disposed on the housing 10 for controlling the switch of the laser generator.

Further, the laser generator includes a laser indicating bulb 70, a refractive element 50, and a lens 14. The laser indicating bulb 70 is connected to the button 15 by a line, and the refractive element 50 is for refracting the emitted laser light to pass through the lens 14.

The refractive element 50 is a transmitting mirror that emits the emitted laser light and emits the laser light from the lens 14 by setting an angle with the laser light. The lens 14 can be made of clear glass or a transparent plastic plate. The lens 14 is disposed at the position of the housing 10, and may be disposed at the front end or one side of the housing 10 according to the measurement requirements of the customer.

As shown in FIG. 1, the lens 14 is disposed at the front end of the casing 10, so that the emission direction of the laser light coincides with the expansion and contraction direction of the tape measure 20, and the tape measure 20 can be assisted for ranging.

As shown in FIG. 2, the lens 14 is disposed on one side of the casing 10, so that the emission direction of the laser light is perpendicular to the expansion and contraction direction of the tape measure 20, and the measured object can be marked by laser assisting when the tape measure 20 performs ranging.
