Description

Technical Field

[0001] The utility model relates to the field of measuring equipment, in particular to a multifunctional laser distance measuring tape. Background Art

[0002] Most existing tape measures only have the function of mechanically measuring length or distance, and their functions are single and cannot meet other measurement needs. When other measurement needs are required, corresponding instruments need to be prepared separately for measurement, which makes it inconvenient to carry and has high cost.

[0003] At present, there are also manufacturers in the market who have integrated the functions of tape measures, adding horizontal projection or laser distance measurement functions. However, in order not to sacrifice the small size and portability of the tape measure, it is impossible to integrate more measurement functions. Some manufacturers have integrated the laser projection and laser distance measurement modules inside the tape measure. However, since the tape measure integrates more functional modules, it is larger in size and relatively thick, which makes it inconvenient to carry and hold. In addition, the laser projection and laser distance measurement modules are directly assembled on the outer shell separately, and the assembly process is relatively complicated and the assembly efficiency is low.

[0037] The utility model provides a multifunctional laser distance measuring tape. Figure 1 As shown, it includes a laser distance measurement module 1, a laser line projection module 2, a tape measure module 3, and a housing 4. The tape measure module 3 is arranged in the housing 4, and an optical bracket 5 is arranged along the radial direction of the tape measure module 3. The laser distance measurement module 1 and the laser line projection module 2 are fixed on the optical bracket 5 in parallel, and the optical bracket 5 has a rear extension portion, and a PCB board 6 is fixed on the rear extension portion. A battery 7 and a key board 8 are also arranged in the housing 4, and a functional physical key 9 is arranged at a position corresponding to the key board 8 on the housing 4.

[0038] Specifically, the front end of the optical bracket 5 has a laser ranging module fixing position and a laser line projection module fixing position. The laser ranging module 1 is fixed to the laser ranging module fixing position by threaded connection or clamp cooperation, and the laser line projection module 2 is fixed to the laser line projection module fixing position by a locking connector.

[0039] It should be noted here that during the installation process, the laser ranging module 1 and the laser projection module 2 are positioned and installed using the positioning and limiting parts on the optical bracket 5 so that both remain in a horizontal state, which helps to reduce errors in subsequent measurements.

[0040] Reference Figure 2 As shown, in this embodiment, the laser ranging module 1 includes a laser emitting tube and a laser receiving assembly, and a light emitting window 41 corresponding to the laser emitting tube and a light receiving window 42 corresponding to the laser receiving assembly are provided on the housing 4. It is necessary to ensure that the light emitting window 41 and the light receiving window 42 are on the same vertical plane. The laser projection module 2 has a built-in light source, and a laser projection window 43 corresponding to the light source is provided on the housing 4.

[0041] Reference Figure 3 As shown, the tape measure module 3 includes a tape measure housing 31, a tape measure core 32 is provided in the tape measure housing 31, a tape measure shaft 33 is provided in the ruler core 32, a tape measure tape 34 is wound on the tape measure shaft 33, and the tape measure shaft 33 is fixed to the tape measure housing 31 through a shaft seat 35. In this embodiment, the tape measure module 3 is connected to the PCB board 6 through the tape measure housing 31. In order to adapt to the circular tape measure housing 31, the rear end of the PCB board 6 is an arc-shaped notch, which can move the tape measure housing 31 forward, reduce space waste, and ensure a more compact and compact structure.

[0042] Reference Figure 2 and Figure 4 As shown, a first tape outlet 311 is provided at the lower part of the tape measure housing 31, and a second tape outlet 44 is provided at the housing 4 corresponding to the first tape outlet 311, and a tape limiter assembly 36 is provided on the path from the first tape outlet 311 to the second tape outlet 44, and the tape limiter assembly 36 is located at the lower side of the optical bracket 5. Here, the tape limiter assembly 36 is arranged at the lower side of the optical bracket 5, which effectively utilizes the lower space of the optical bracket 5 and provides a mounting position for the limiter assembly 36.

[0043] In this embodiment, the tape limit assembly 36 includes a soft rubber button 361 and a top plate 362. The upper end of the soft rubber button 361 is provided with an arc surface that matches the lower end surface of the tape 34. The top plate 362 is fixed in the housing 4 and located at the lower side of the optical bracket 5. The tape 34 passes between the soft rubber button 361 and the top plate 362. Compared with the traditional tape measure, the limit part of the tape 34 is advanced, and the corresponding top plate 362 is arranged above it, so that the structure is more solid and the limit locking effect is better.

The display screen 46 is used to display the measurement data, and the measuring button 47 is used to control the measurement process. Specifically, a display screen 46 is provided on the upper end surface of the tape measure module 3, and a measuring button 47 for long-distance laser ranging is provided at the rear end of the display screen 46, so that the measuring button 47 is separated from the physical function button 9 provided on the side, which is convenient for use during measurement, and solves the problem that the existing laser ranging tape measures mix the measuring button with the physical function button, which is inconvenient to operate.
