Referring to fig. 1, the shape of the existing laser tape measure is a tape measure model, that is, the laser distance measuring assembly 2 is integrated in the tape measure housing 1, and the laser distance measuring assembly 2 and the tape measure assembly are generally arranged side by side along the width direction of the tape measure housing 1. In this case, the keys and display of the laser distance measuring assembly 2 are typically located on the left or right side wall of the tape measure housing 1. Therefore, when the laser measuring tape is used, after a user places the laser measuring tape on a surface to be measured, the thumb is inconvenient to press the laser measuring tape, even the key is inconvenient to operate by two hands, or the measuring tape inclines towards the force application direction of the thumb when the key is pressed by one hand, so that the measurement precision is influenced.

Accordingly, the present application provides a laser tape measure that takes the form of a hand-held laser range finder and the laser range finder module 30 and the tape measure module 20 are arranged in series along the length of the hand-held housing, i.e. at the two ends of the hand-held housing 10 respectively. Firstly, the appearance of the hand-held laser range finder is adopted, so that the use of the laser range finding function is convenient, and for the tape measure function, the tape measure module 20 is positioned at one end of the hand-held shell 10, namely, the laser range finding module at the other end does not influence the use of the tape measure function. Therefore, the normal use of the laser ranging function and the tape measure function is considered, the use by a user is facilitated, and the normal operation of the respective functions cannot be influenced.

The inventive concept of the present application is further illustrated below with reference to some specific embodiments.

Referring to fig. 2, a laser tape measure includes: a hand held housing 10, a tape measure module 20 and a laser ranging module 30.

The handheld housing 10 is a cylindrical structure, and may be a rectangular parallelepiped structure adopted by a general handheld laser range finder, or may be another prismatic structure. It will be readily appreciated that the shape of the hand held housing 10 is a rectangular parallelepiped or other cylindrical shape that is a perfect fit to the overall shape of the hand held housing 10 and does not represent that the housing shape cannot be configured with chamfers, anti-slip grooves, and recesses or other secondary designs that do not detract from the overall shape of the housing.

The hand held housing 10 may include an upper housing and a lower housing, which are detachably connected by screws or the like. Alternatively, the upper and lower housings may be detachably connected by means of a snap fit.

The handheld housing 10 has a tape measure cavity and a laser ranging module cavity sequentially arranged along the length direction of the handheld housing 10. Namely, the tape measure cavity and the laser ranging module cavity are respectively positioned at two ends of the shell of the handheld laser range finder. One end of the cavity is provided with a laser ranging module cavity which is used for installing the laser ranging module 30. The laser ranging module 30 may be mounted within the laser ranging cavity by a snap fit or screws or other equivalent means. The other end is provided with a corresponding tape cavity according to the shape of the relevant part of the tape module 20. For example, referring to fig. 2 and 3, the up and down directions in fig. 2 and 3 are the length directions of the hand held housing 10.

Specifically, the tape measure module 20 is disposed within the tape measure cavity, and the laser ranging module 30 is disposed within the laser ranging module.

Due to the technical characteristics, compared with the prior art that the tape measure module and the laser ranging module are integrated in the tape measure housing 1 along the width direction of the tape measure housing 1, the tape measure module 20 is integrated in the handheld housing 10 of the handheld laser range finder, and the laser ranging module 30 and the tape measure module 20 are sequentially arranged along the length direction of the handheld housing 10, so that the tape measure module 20 does not damage the overall appearance of the handheld housing 10. That is, the addition of the tape module 20 does not affect the normal use of the laser ranging function of the laser tape module 30, i.e., the operation of the laser ranging function is consistent with the operation of the conventional hand-held laser rangefinder. Also, since the tape measure module 20 is located at the other end of the hand held housing 10, the tape measure module 20 can be used normally. For example, the tape measure cavity is added by lengthening the overall length of the hand held housing 10, and the tape measure module is added thereto, without compromising the overall appearance of the housing. Therefore, the normal use of the laser ranging function and the tape measure function is considered, and the use by a user is facilitated.

The arrangement of the hand held housing is further explained below. One end of the traditional handheld laser range finder is a transmitting end, and a laser tube is installed at the transmitting end and used for transmitting and measuring the light velocity. And the other end opposite to the measuring end is a measuring end which is used for placing the handheld shell on a measuring surface or a reference surface opposite to the object to be measured. Thus, the measuring end has a measuring reference surface. After the measuring reference surface is attached to the object to be measured or attached to the belt measuring surface or attached to the reference surface opposite to the object to be measured, the laser measuring tape can start laser ranging.

In some embodiments, referring to fig. 3 and 4, along the length of the hand held housing 10, the hand held housing 10 includes a transmitting end far away from the tape measure cavity and a measuring end opposite to the transmitting end, and the end surface of the measuring end has a measuring reference surface a.

I.e. the emitting end is located at the end of the hand held housing 10 where the laser ranging module 30 is mounted and the measuring end is located at the other end of the hand held housing 10 where the tape measure module 20 is mounted. Since the measuring end is primarily the measuring datum surface a, the measuring end does not disrupt the functional normal use of the tape measure module 20.

In one embodiment, the measuring end has a tape outlet 11, the tape outlet 11 communicates with the tape measure cavity, and the tape 21 of the tape measure module can extend out of the hand casing 10 along the length of the hand casing 10.

The tape outlet 11 is located at the measuring end, i.e. at the end of the hand-held housing 10 remote from the laser ranging module 30, and the tape 21 of the tape module 20 is extended or retracted from the tape outlet 11. That is, in the laser measuring tape provided by this embodiment, the measuring tape cavity and the laser ranging cavity may not be communicated with each other and do not affect each other.

The specific structure of the tape outlet 11 is further described below, and in some embodiments, the tape outlet includes a first notch and a second notch. The first notch is arranged on the end face of the measuring end; the second gap is opened on the side wall of the handheld shell 10, and the first gap is communicated with the second gap. Referring to fig. 2, the end of the tape can abut against the wall of the second notch. I.e. when the tape measure module 20 is not in use, the tape end does not extend beyond the measuring datum level a, so as not to interfere with the use of the measuring datum level a.

Referring to fig. 2 and 4, the tape outlet 11 is disposed on one side edge of the measuring end, and includes a first notch disposed on an end surface of the measuring end and a second notch disposed on a side wall of the handheld housing 10. That is, the appearance of the housing of the handheld laser range finder is not changed by the arrangement of the tape outlet 11, so that the laser range finding function of the laser range finder module can be conveniently used.

In order to further facilitate the use of the laser range finding function of the laser range finder, for example, the second notch is provided in one side wall in the width direction of the hand-held housing 10. That is, the hand-held housing 10 can be normally placed on a plane, and the tape outlet is suspended without affecting the placement of the hand-held housing. Here, referring to fig. 2 and 3, the left-right direction is the width direction of the hand-held housing 10.

Specifically, the tape measure module includes a shaft and a tape measure wheel, the shaft is disposed in the tape measure cavity and extends along the height direction of the hand-held housing 10. The tape wheel is sleeved on the shaft rod, the tape 21 is wholly or partially wound on the tape wheel, and the fixed end of the tape 21 is fixedly connected to the tape wheel.

In the laser tape adopting the technical scheme, the installation of the tape wheel is suitable for the appearance of the handheld shell 10, and when the laser tape is used, the function of the tape is consistent with the use habit of the existing laser range finder and the use habit of the tape regardless of the use of the laser range finding function.

To facilitate reading, tape measures are typically provided with a push button for releasing or stopping the extension or retraction of the tape measure. For example, referring to FIG. 4, in some embodiments, a push button hole 12 is formed in an end surface of the measuring end, a push button 22 of the tape module 20 is disposed in the push button hole 12, and the push button 22 is used to release or stop the extension and retraction of the tape. Wherein the push button 22 is located on one side of the measurement reference plane a. That is, the push button 22 is hidden in the push button hole 12, and the highest position of the push button 22 does not exceed the measurement reference plane a. The push button 22 does not interfere with the use of the measurement reference plane a during pressing.

Specifically, the front side wall of the handheld housing 10 is provided with a distance measuring button 4, and the distance measuring button 4 is used for controlling the on/off of the laser generator of the laser distance measuring module 30. The front side wall of the handheld housing 10 is provided with a through hole matching with the shape of the liquid crystal display device 31, and the liquid crystal display device 31 is clamped in the through hole.

That is, the distance measuring button 4 and the liquid crystal display device 31 of the laser tape measure provided by the present embodiment are both located on the front side wall of the handheld housing 10, and the user uses the laser tape measure to operate the laser tape measure in accordance with the conventional handheld laser distance measuring instrument.
