DETAILED DESCRIPTION

[0034] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0035] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0036] like Figures 1 to 4 As shown, according to a preferred embodiment of the utility model, a distance measurement and line projection device integrates a laser distance measurement module 20 and a laser line projection module 30 in a housing 10, so that the positioning of the laser distance measurement module 20 and the laser line projection module 30 can be achieved in one operation, thereby avoiding the error caused by manual positioning twice, and improving the measurement accuracy and work efficiency. At the same time, by using a laser line projection module 30 that can project a laser line with a scale, the distance measurement can be achieved, and the scope of application is improved.

[0037] Specifically, Figure 2 As shown, the distance measurement and line projection device includes a housing 10, a laser distance measurement module 20 and a laser line projection module 30. The housing 10 is used to accommodate components such as the laser distance measurement module 20 and the laser line projection module 30; the laser distance measurement module 20 is used to measure the distance, and is assembled in the housing 10. The laser line projection module 30 is used to project a laser line with a scale, and is also assembled in the housing 10 and is located below the laser distance measurement module 20. In other words, the laser distance measurement module 20 and the laser line projection module 30 are integrated in the housing 10. The laser distance measurement module 20 here is the existing laser distance measurement module 20, and the laser line projection module 30 is the existing laser line projection module 30. The specific structure will not be repeated here one by one.

[0038] The distance measurement and line projection device described in the utility model can realize simultaneous positioning of the laser distance measurement module 20 and the laser line projection module 30 through one positioning operation by integrating the laser distance measurement module 20 and the laser line projection module 30 into the housing 10, thereby avoiding the operation error caused by two positioning operations, improving the measurement accuracy and the work efficiency. In addition, by integrating the laser distance measurement module 20 and the laser line projection module 30 into the housing 10, it is also convenient to carry and place.

[0039] Furthermore, the laser line projection module 30 can project a first laser line with a scale, or a first laser line and a second laser line with a scale. Figure 5 It is a schematic diagram showing that the laser line projection module 30 projects a first laser line and a second laser line with scales.

[0040] Specifically, the laser line projection module 30 includes a distance measuring unit, a line projection unit and a calculation unit. The distance measuring unit is used to measure the straight-line distance L between the distance measuring line projection device and the measuring point of the projection plane. The line projection unit is used to project a first laser line with a scale on the projection plane, or to project a first laser line and a second laser line with a scale on the projection plane. The distance between two adjacent scales on the first laser line is the first scale spacing D1, and the distance between two adjacent scales on the second laser line is the second scale spacing D2. The first ratio between the straight-line distance L and the first scale spacing D1 is fixed or the angle of the vertex angle of the right triangle formed by two adjacent scales and the laser emission port of the distance measuring unit is fixed, and the second ratio between the straight-line distance L and the second scale spacing D2 is fixed.

[0041] The calculation unit is in communication with the distance measuring unit, and is used to calculate the first scale spacing according to the straight-line distance L, and one of the first ratio D1 and the vertex angle, or to calculate the second scale spacing according to the ratio between the straight-line distance L and the second scale spacing D2.

[0042] In a specific implementation, for the case of projecting only the first laser line, the straight-line distance between the laser line projection module 30 and the measuring point of the projection plane is L, the distance between two adjacent scales on the first laser line is D1, and the ratio between the straight-line distance L and the scale spacing D1 is fixed, or the angle of the vertex angle θ of the right triangle formed by two adjacent scales and the laser emission port of the laser line projection module is fixed, and the ratio or the angle of the vertex angle θ is associated with the structure of the laser line projection module, that is, once the laser line projection module 30 is configured and shipped out of the factory, the ratio or the angle of the vertex angle θ is fixed, and the laser line projection module 30 can calculate the scale spacing D1 based on the straight-line distance L and one of the ratio and the vertex angle θ.

[0043] For the case of simultaneously projecting the first laser line and the second laser line, the calculation of the scale spacing D1 on the first laser line can be referred to above, and will not be repeated here. As for the scale spacing D2 on the second laser line, it can be calculated based on the straight-line distance L between the laser projection module 30 and the measurement point on the projection plane. This is because the ratio between the straight-line distance L and the scale spacing D2 is fixed, and the ratio has been fixed after the laser projection module 30 leaves the factory. By measuring the spacing, the functions and application scenarios of the laser projection module 30 can be expanded.

[0044] Furthermore, if Figure 1 As shown, the housing 10 is provided with a first window 11 corresponding to the laser ranging module 20, and a second window 12 corresponding to the laser line projection module 30, and the second window 12 is preferably a cross-shaped window.

[0047] Furthermore, combined with Figure 2 and Figure 3 As shown, the bracket 40 includes a platform portion 41 and a support portion 42.
