[0067] The following describes several preferred embodiments of the present invention with reference to the accompanying drawings to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the scope of protection of the present invention is not limited to the embodiments mentioned herein.

[0068] In the drawings, components with identical structures are denoted by the same reference numerals, and components with similar structures or functions are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrary and are not limited by the present invention. For clarity, the thickness of components in some places in the drawings is appropriately exaggerated.

[0069] Example 1

[0070] like Figure 1-6 As shown, the multifunctional measuring device 10 of this embodiment includes a housing 100 , wherein the housing 100 has a cavity 101 therein, and a laser module 110 and a horizontal assembly 120 are disposed in the cavity 101 .

[0071] 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 .

[0072] The housing 100 has a first end 103 and a second end 104 that are relatively arranged. The laser module 110 is arranged at the first end 103 of the housing 100, and the tape measure module 140 is arranged at the second end 104 of the housing 100. A light outlet 105 is provided on the first end 103 of the housing 100. The laser module 110 can emit laser, and the generated laser is emitted through the light outlet 105. In some embodiments, the laser emitted by the laser module 110 forms a point laser after passing through the light outlet 105, which can be used to realize a dot-marking function. In some embodiments, the laser emitted by the laser module 110 forms a line laser after passing through the light outlet 105, which is used to realize a line-marking function. In some embodiments, the laser module 110 can switch between a point laser and a line laser. Preferably, the multifunctional measuring device 10 includes a switching component 111. By controlling the switching component 111, the laser emitted by the laser module 110 can be switched between a point laser and a line laser after being emitted through the light outlet 105 of the housing 100. In some embodiments, as Figure 4As shown, the switching assembly 111 includes a sliding member 112 and a push button 113. The sliding member 112 is arranged between the laser module 110 and the light outlet 105 of the housing 100, and the sliding member 112 is slidable relative to the housing 100. The sliding member 112 is provided with a through hole 114 and a beam splitter 115 in sequence along a sliding direction X. When the sliding member 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 emitted by the laser module 110 is emitted from the light outlet 105 after passing through the beam splitter 115, thereby generating linear laser. When the sliding member 112 is moved to a second position, the through hole is located between the light outlet 105 and the laser module 110. The laser emitted by the laser module 110 is emitted from the light outlet 105 after passing through the through hole, thereby generating point laser. The push button 113 is connected to the sliding member 112 and protrudes out of the housing 100. An external force applied to the push button 113 can drive the sliding member 112 to slide along the housing 100. Preferably, the sliding direction X of the sliding member 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 realized by using appropriate hardware circuit or by software program control, and is not limited to the mechanical structure shown in the figure.

[0073] 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, Figure 5 The power module 130 can use a dry battery, a rechargeable battery, or the like as a power source. A power switch 132 is arranged at an opening 131 provided on a side wall of the housing 100.

[0074] The horizontal assembly 120 includes a first water bubble 121 arranged in the housing 100. An observation window 123 is arranged on the side wall of the housing 100 corresponding to the first water bubble 121, so that the state of the first water bubble 121 can be observed. The first water bubble 121 can be a horizontal bubble for measuring the levelness for leveling; or the first water bubble 121 can be an angle bubble which can be rotated for measuring the angle. Preferably, the first water bubble 121 is an angle bubble, the observation window 123 is annular, and an angle scale 124 is arranged at the observation window 123. The angle scale 124 is annular, and different angle leveling can be achieved by the rotation of the first water bubble 121 and the angle scale 124.

[0075] In some embodiments, the horizontal assembly 120 further includes a second water bubble 122. The second water bubble 122 can be arranged in the housing 100, and then an observation opening is arranged on the housing 100 corresponding to the second water bubble 122, which is the same as the arrangement of the first water bubble 121. In another embodiment, as shown, Figure 5As shown, a recessed portion 125 is provided on one side of the housing 100. The recessed portion 125 is formed from the side wall of the housing 100, and the second water bubble 122 can be installed in the recessed portion 125. Preferably, the recessed portion 125 is provided at the side wall of the housing 100 along the length direction.

[0076] 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.

[0077] 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 be a tape measure structure known in the art. For example, see Figure 6 The tape measure module 140 includes a tape wheel 141, a tape 142, a tape outlet 143, a pressure block 144, and a locking key 145. The tape wheel 141 is disposed within the housing 100. The tape 142 is fully or partially wound around the tape wheel 141. One end of the tape 142 is fixedly connected to the tape wheel 141, and the other end is provided with a ruler end. The tape outlet 143 is disposed on a side wall of the housing 100, preferably at an end of the side wall. The ruler end extends outside the housing 100 through the tape outlet 143. The pressure block 144 is disposed within the housing 100 and near the tape outlet 143. When the tape 142 is pulled out of the housing 100, the pressure block 144 is used to compress the tape 142, ensuring that its length outside the housing 100 remains unchanged. The locking key 145 is disposed on the outer surface of the housing 100 and is used to control whether the pressure block 144 compresses or releases the tape 142. It should be understood that the structure of the tape measure module 140 is not limited to the solution described here, and tape measure modules 140 with other structures can also be applied in this embodiment.

[0078] 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.

[0079] 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.
