For clarity, the thickness of components in some places in the drawings is appropriately exaggerated.

[0070] Example 1

[0071] As shown in FIG. 1-6 , the multifunctional measuring device 10 of this embodiment includes a housing 100 . The housing 100 has a cavity 101 therein. A laser module 110 and a leveling assembly 120 are disposed in the cavity 101 .

[0072] The housing 100 can be made of plastic or metal, preferably plastic. In some embodiments, the housing 100 includes a first shell 102 and a second shell 103 , which are disposed opposite to each other and connected by fasteners to form a cavity 101 .

[0073] The housing 100 has a first end 103 and a second end 104 disposed opposite each other. The laser module 110 is disposed at the first end 103 of the housing 100, and the tape measure module 140 is disposed at the second end 104 of the housing 100. A light outlet 105 is provided at the first end 103 of the housing 100. The laser module 110 can emit laser light, which is emitted through the light outlet 105. In some embodiments, the laser light emitted by the laser module 110 forms a point laser after passing through the light outlet 105, which can be used to implement a dot-marking function. In some embodiments, the laser light emitted by the laser module 110 forms a line laser after passing through the light outlet 105, which can be used to implement a line-marking function. In some embodiments, the laser module 110 can switch between point laser and line laser patterns. Preferably, the multifunctional measuring device 10 includes a switching component 111. By controlling the switching component 111, the laser light emitted by the laser module 110 can be switched between point laser and line laser patterns after being emitted through the light outlet 105 of the housing 100. In some embodiments, as shown in FIG4 , the switching assembly 111 includes a slider 112 and a push button 113 . The slider 112 is disposed between the laser module 110 and the light outlet 105 of the housing 100 , and the slider 112 is slidable relative to the housing 100 . The slider 112 is provided with a through hole 114 and a beam splitter 115 in sequence along the sliding direction X. When the slider 112 is moved to a first position, the beam splitter 115 is located between the light outlet 105 and the laser module 110 . At this time, the laser light emitted by the laser module 110 passes through the beam splitter 115 and is emitted from the light outlet 105 , generating a linear laser. When the slider 112 is moved to a second position, the through hole is located between the light outlet 105 and the laser module 110 . The laser light emitted by the laser module 110 passes through the through hole and is emitted from the light outlet 105 , generating a point-shaped laser. The push button 113 is connected to the slider 112 and protrudes outside the housing 100. Applying an external force to the push button 113 can drive the slider 112 to slide along the housing 100. Preferably, the sliding direction X of the slider 112 is consistent with the height direction of the housing 100. It should be understood that the point-line switching function of the laser module 110 can be implemented by configuring a suitable hardware circuit or through software program control, and is not limited to the mechanical structure shown in the figure.

[0074] In some embodiments, the multifunctional measuring device 10 can be powered by an external power source. In some embodiments, the multifunctional measuring device 10 can include a power module 130. As shown in FIG5 , the power module 130 is disposed within the housing 100. This power module 130 can utilize dry cell batteries, rechargeable batteries, or the like as a power source. An opening 131 is provided on a side wall of the housing 100, and a power switch 132 is disposed within the opening 131.

[0075] The leveling assembly 120 includes a first bubble 121 disposed within the housing 100. An observation window 123 is provided on the sidewall of the housing 100, corresponding to the first bubble 121, through which the status of the first bubble 121 can be observed. The first bubble 121 can be a level bubble, used to measure horizontality for leveling; or it can be a rotatable angle bubble, used to measure angles. Preferably, the first bubble 121 is an angle bubble, and the observation window 123 is annular. An angle scale 124 is provided at the observation window 123. The angle scale 124 is annular, and the rotation of the first bubble 121 and the angle scale 124 can achieve leveling at different angles.

[0076] In some embodiments, the horizontal assembly 120 further includes a second water bubble 122. The second water bubble 122 can be disposed within the housing 100, and an observation port can be provided on the housing 100 corresponding to the second water bubble 122, similar to the arrangement of the first water bubble 121. In another embodiment, as shown in FIG5 , a recessed portion 125 is provided on one side of the housing 100. The recessed portion 125 is recessed from the sidewall of the housing 100, and the second water bubble 122 can be mounted within the recessed portion 125. Preferably, the recessed portion 125 is provided on the sidewall of the housing 100 along its length.

[0077] In some embodiments, in order to more clearly observe the state of the bubble, a light source is provided at the first bubble 121 and / or the second bubble 122. By turning on the light source, the bubble state can be observed in a dark area. Preferably, the light source can be an LED light.

[0078] In some embodiments, the multifunctional measuring device 10 further includes a tape measure module 140. The tape measure module 140 is disposed within the housing 100 and can employ a tape measure structure known in the art. For example, referring to FIG6 , the tape measure module 140 includes a tape measure wheel 141, a tape measure 142, a tape outlet 143, a pressure block 144, and a locking key 145. The tape measure wheel 141 is disposed within the housing 100, and the tape measure 142 is fully or partially wound around the tape measure wheel 141. One end of the tape measure 142 is fixedly connected to the tape measure wheel 141, and the other end is provided with a tape end. The tape outlet 143 is disposed on a side wall of the housing 100, preferably at an end of the side wall. The end of the tape measure extends out of the housing 100 through the tape outlet 143. A pressure block 144 is located within the housing 100 near the tape outlet 143. When the tape measure 142 is pulled out of the housing 100, the pressure block 144 can be used to compress the tape 142, maintaining the same length outside the housing 100. A locking key 145 is located on the outer surface of the housing 100 and is used to control the pressure block 144 to tighten or loosen the tape 142. It should be understood that the structure of the tape measure module 140 is not limited to the one described herein; tape measure modules 140 with other structures can also be used in this embodiment.

[0079] In some embodiments, a 90° corner 150 is provided on one side of the housing 100. Specifically, the corner 150 includes a first side 151 and a second side 152, which intersect at a 90° angle. During use, the first side 151 and the second side 152 of the corner 150 respectively contact two right-angled edges of the object to be positioned. Combined with the leveling function of the laser module 110 and / or the water bubble, the positioned object can be quickly suspended horizontally. Alternatively, the corner 150 can be used to check whether an already positioned object is level. For example, the corner 150 can be aligned with two right-angled edges of the positioned object, and then the laser module 110 and / or the water bubble can be used to check whether the object is level. Preferably, the vertex of the corner 150 is rounded 153, that is, the intersection of the first side 151 and the second side 152 is rounded 153 to prevent interference between the vertex of the corner 150 and the object.

[0080] The multifunctional measuring device 10 provided in this embodiment can project laser light to identify lateral lines and measuring points for leveling and alignment. The first and second water bubbles 121, 122 enable quick and accurate leveling. The 90° corners 150 enable horizontal suspension of square objects. The tape measure module 140 enables distance measurement.
