[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-6 , a wall decoration flatness detection device, comprising a wall connection device 1, the wall connection device 1 is used to be attached to the corner of the wall 4;

[0032] A laser emitter 2 is installed inside the wall connection device 1, and the laser emitter 2 is used to emit a laser beam 5 that is flush with the surface of the wall 4;

[0033] The wall connection device 1 includes a ∟-shaped housing 101. The inner walls on both sides of the ∟-shaped housing 101 are provided with light channels 102. The inner corners of the ∟-shaped housing 101 are provided with concave chambers 103.

[0034] The laser emitter 2 is installed inside the concave chamber 103. The laser emitter 2 emits a laser beam 5 into the light channel 102. The laser beam 5 emitted by the laser emitter 2 is flush with the inner wall of the ∟-shaped housing 101. The light emitting principle of the laser emitter 2 is the same as that of a laser level.

[0035] A battery compartment 105 and a power switch 106 are provided on the ∟-shaped housing 101 . A battery is provided inside the battery compartment 105 . The battery is electrically connected to the laser emitter 2 . The power switch 106 is used to control the on and off of the current of the laser emitter 2 .

[0036] Through the above technical solution, an L-shaped ∟-shaped housing 101 is provided, and the inner wall of the ∟-shaped housing 101 is attached to the corner of the wall 4, and light channels 102 are opened on the inner walls on both sides of the ∟-shaped housing 101. At the same time, a concave chamber 103 is opened at the inner corner of the ∟-shaped housing 101 to install the laser emitter 2. The laser light 5 emitted from the inside of the light channel 102 is level with the surface of the wall 4. When the wall 4 is convex, the light is blocked. When the wall 4 is concave, a gap is left between the concave part and the laser light 5, and the light cannot be irradiated into the concave part, thereby achieving the effect of conveniently detecting the flatness of the wall.

[0037] The laser beam 5 emitted by the device extends in two directions at a vertical angle, so that two walls can be inspected at the same time, improving the efficiency of the inspection.

[0038] In addition to testing the flatness of walls, the device can also test the flatness of the outer surfaces of furniture.

[0039] The shape of the ∟-shaped housing 101 of the present device is not limited to the styles shown in the drawings of the specification, and any structure can be used as long as the laser light 5 emitted by the laser emitter 2 is level with the surface of the wall 4.

[0040] Specifically, there are multiple light channels 102 on the same side, the multiple light channels 102 are parallel to each other, and the opening heights of the light channels 102 on both sides are staggered.

[0041] The number of the laser emitters 2 is equal to the number of the light channels 102 , and the distribution positions of the laser emitters 2 are adapted to the positions of the light channels 102 .

[0042] Through the above technical solution, multiple light channels 102 and laser emitters 2 adapted to the number of light channels 102 are set. During detection, multiple laser beams 5 will be emitted simultaneously to increase the detection range and improve the detection efficiency;

[0043] The purpose of staggering the light channels 102 on both sides is to avoid mutual interference between the laser beams 5 emitted by the laser emitters 2 on both sides. In order to make the laser beams 5 emitted by the laser emitters 2 stick to the wall, the laser emitters 2 need to be installed inside the concave chamber 103, and the laser emitters 2 on both sides should emit the laser beams 5 at a vertical angle to the inside of the light channel 102.

[0044] Otherwise, the laser emitter 2 can only be installed to protrude from the inner wall of the ∟-shaped shell 101 so that the emitted laser light 5 can be horizontally fitted with the inner wall of the ∟-shaped shell 101. However, if installed in this way, the inner wall of the ∟-shaped shell 101 will not be able to be horizontally fitted with the inner wall of the ∟-shaped shell 101 due to the obstruction of the laser emitter 2.

[0045] Specifically, baffles 104 are fixedly connected to the upper and lower sides of the concave chamber 103 , the inner wall of the baffle 104 is level with the inner wall of the ∟-shaped shell 101 , and the baffle 104 overlaps the corner of the wall 4 .

[0046] Through the above technical solution, the purpose of installing the baffle 104 is to block the corner of the wall 4. If the two ends of the concave chamber 103 are open, when the ∟-shaped shell 101 is placed at the corner of the wall 4, the corner of the wall 4 will extend to the inside of the concave chamber 103 and contact the laser emitter 2, making the laser emitter 2 easily damaged. Therefore, the baffle 104 is set to limit the extension depth of the wall 4.

[0047] Specifically, there are two battery compartments 105 and two power switches 106 , and the two battery compartments 105 and the two power switches 106 are respectively located on both sides of the outer surface of the ∟-shaped housing 101 ;

[0048] The battery compartment 105 and the power switch 106 respectively provide power and on-off control to the laser emitter 2 on the same side.

[0049] Through the above technical solution, two battery compartments 105 and power switches 106 are set, so that the laser emitter 2 on the corresponding surface is powered separately through the battery compartment 105, and the two power switches 106 are also set to control the laser emitter 2 on the corresponding surface separately, so that when performing detection, the laser emitter 2 on one side can be turned on for use separately.

[0050] Specifically, a chamfered corner is provided at a corner of the outer surface of the ∟-shaped housing 101, and the hand-held mechanism 3 is fixedly connected to the chamfered corner.

[0051] Through the above technical solution, a bevel angle is set at the corner of the outer surface of the ∟-shaped shell 101, so that the connection of the hand-held mechanism 3 is more convenient, and when holding the hand-held mechanism 3, the hand will not come into contact with the ninety-degree angle, causing inconvenience in holding.

[0052] Specifically, the hand-held mechanism 3 includes a hand-held handle 301 , a connecting sleeve 302 is fixedly connected to the bottom of the hand-held handle 301 , and an extension rod 303 is inserted into the interior of the connecting sleeve 302 .

[0053] Through the above technical solution, the provided handheld handle 301 is used to facilitate handheld operation of the device, and the provided connecting sleeve 302 is used to install an extension rod 303 when inspecting a high wall 4. The height of the device is extended by the extension rod 303, so that high walls can be inspected without the use of a ladder or platform.

[0054] Specifically, the extension rod 303 is detachably connected to the interior of the connecting sleeve 302 , and the extension rod 303 is a multi-section telescopic rod.

[0055] Through the above technical solution, the extension rod 303 is configured to be separable from the connecting sleeve 302, thereby improving the convenience of storing and carrying the device. The extension rod 303 is retractable, so that the length can be adjusted according to usage needs and the space occupied can be reduced when stored.

[0056] When in use, an L-shaped ∟-shaped housing 101 is provided, and the inner wall of the ∟-shaped housing 101 is attached to the corner of the wall 4, and light channels 102 are opened on the inner walls on both sides of the ∟-shaped housing 101. At the same time, a concave chamber 103 is opened at the inner corner of the ∟-shaped housing 101 to install the laser emitter 2. The laser light 5 emitted from the inside of the light channel 102 is level with the surface of the wall 4. When the wall 4 is convex, the light is blocked. When the wall 4 is concave, a gap is left between the concave part and the laser light 5, and the light cannot be irradiated into the concave part, thereby achieving the effect of conveniently detecting the flatness of the wall.

[0057] By fixing the handheld handle 301 at the outer corner of the ∟-shaped shell 101, it is convenient to hold it during detection. At the same time, the connecting sleeve 302 is fixedly connected to the bottom of the handheld handle 301. After the extension rod 303 is inserted into the connecting sleeve 302, it is convenient to detect the high part of the wall 4, achieving the effect of easy use.

[0058] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
