Description

Technical Field

[0001] This utility model relates to the technical field of target boards for line projectors, and specifically to a target board for line projectors. Background Technology

[0002] A laser level (also known as a laser projection device or laser level) is a measuring tool that uses laser technology to project horizontal, vertical, or intersecting lines. It is widely used in construction, decoration, carpentry, installation, and other fields. It projects clear reference lines onto walls, floors, or other surfaces using a laser beam, helping users quickly and accurately complete tasks such as leveling, alignment, and positioning.

[0003] Existing projection devices use target plates that reflect light diffusely. This diffuse material scatters light in all directions, causing a sharp decrease in light intensity at long distances. As a result, the amount of reflected light is low and the image is not clear when illuminating from a distance. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a target plate for a line projector, comprising:

[0005] The target board is a transparent board, with a front end and a rear end on its two sides, respectively.

[0006] The support frame is rotatably connected to the rear end of the target plate. Flipping the support frame forces it to be positioned at various angles to form various different angles with the target plate. The support frame can be adjusted to form an acute angle or be parallel to the target plate in various positions.

[0007] The front film is a reflective film, which is attached to the front end of the target plate;

[0008] A backlight sticker is attached to the rear end of the target board.

[0009] In a further embodiment of this invention, the front film is a micro-mirror reflective material film.

[0010] In a further embodiment of this invention, the backlight sticker is an adhesive matte silver paper backlight sticker.

[0011] In a further embodiment of this invention, a first positioning groove for adapting and accommodating the front adhesive film is provided on the front end of the target plate, and the front adhesive film is attached to the first positioning groove.

[0012] In a further embodiment of this invention, a second positioning groove for adapting and accommodating a backlight sticker is provided on the rear end of the target board, and the backlight sticker is attached to the second positioning groove.

[0013] In a further embodiment of this utility model, two symmetrically arranged protrusions are provided on the rear edge of the target plate, and a connecting hole is provided on the opposite side of the protrusion. The support frame has elastic arms on both sides, and a connecting shaft is provided on the inner side of the elastic arms. The support frame is rotatably connected to the connecting hole on the protrusion through the connecting shaft.

[0014] In a further embodiment of this utility model, two positioning holes are provided on the protrusion at different positions outside the connecting hole, and a protrusion is provided on the elastic arm outside the connecting shaft. The protrusion is adapted to and engaged with the positioning holes. When the support frame rotates to the point where the protrusion is positioned on the positioning holes at different positions, the support frame and the target plate form an acute angle or are parallel to each other.

[0015] In a further embodiment of this invention, a support tip is formed at the outer corner of the protrusion. When the support frame and the target plate are at an acute angle, the support tip extends out from the lower side of the elastic arm, so that the support tip and the support edge on the side of the support frame away from the elastic arm at the bottom form a multi-point support structure placed on a plane.

[0016] In a further embodiment of this invention, the support frame is provided with hanging holes.

[0017] In a further embodiment of this utility model, the support frame is provided with mounting holes symmetrically on both sides of the hanging hole, and a magnet is fixed in the mounting hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This projector's target plate uses a non-diffuse reflection method, employing a combination of a microprism reflective film and an adhesive matte silver backlight sticker. A microprism reflective film is attached to the front of the target plate, while an adhesive matte silver backlight sticker is attached to the rear. The target plate is made of transparent material. When light shines on the surface of the front film, it undergoes multiple refractions and total internal reflections. The backlight sticker, acting as a backing, reflects the light back to the front film, further enhancing the total reflected light intensity. Ultimately, this concentrates the light and reflects it back towards the light source, significantly reducing energy loss. Therefore, it allows for efficient reflection even at long distances, enabling the capture of clear targets.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0033] This embodiment provides a target board for a line projector, including:

[0034] The target plate 1 is a transparent plate, with a front end and a rear end on its two sides, allowing light to pass through to the rear end.

[0035] It also includes a support frame 2, which is rotatably connected to the rear end of the target plate 1. Flipping the support frame 2 forces it to be positioned at various angles to form different angles with the target plate 1. The support frame 2 can be adjusted to form an acute angle or be parallel to the target plate 1 in various positions. When in the acute angle position, the target plate 1 can be placed on a flat surface. When in the parallel position, the target plate 1 can be suspended or hung. When the target plate 1 and the support frame 2 are in the parallel position, there is also a folded state in which the support frame 2 is completely attached to the back of the target plate 1 for easy storage and to meet various practical application needs.

[0036] It also includes a front film 3, which is a reflective film. The front film 3 is attached to the front end of the target plate 1. More preferably, the front film 3 is a micro-prism reflective film. The micro-prism reflective film is a reflective material composed of countless micro-prism arrays. It is commonly found in traffic signs, reflective vests, etc. Therefore, it is an existing material, so it will not be described in detail in this embodiment.

[0037] It also includes a backlight sticker 4, which is attached to the rear end of the target plate 1. More preferably, the backlight sticker 4 is an adhesive matte silver paper backlight sticker 4. The adhesive matte silver paper backlight sticker 4 is also an existing material, which will not be described in detail in this embodiment. It usually has a variety of effects such as matte silver coating and backing reflection.

[0038] Compared to traditional diffuse reflection methods, this embodiment uses a combination of a microprism reflective film and an adhesive matte silver backlight sticker 4. A front film 3 of microprism reflective material is attached to the front end of the target board 1, and an adhesive matte silver backlight sticker 4 is attached to the rear end of the target board 1. The target board 1 is a transparent board. When light shines on the surface of the front film 3, it undergoes multiple refractions and total internal reflections. The backlight sticker 4 acts as a backing to reflect the light back to the front film 3. The matte silver coating on the backlight sticker 4 can avoid the glare problem of specular reflection. The opacity of the backlight sticker 4 blocks transmitted light, ensuring that all incident light is effectively reflected, further enhancing the total reflected light intensity. The light incident on the front film 3 and the light reflected back by the front film 3 are parallel, ultimately causing the light to be concentrated and reflected back to the light source direction, greatly reducing energy loss. Therefore, it can reflect light efficiently at a long distance and capture a clear target.

[0039] In this embodiment, specifically, a first positioning groove 10 for accommodating and accommodating the front film 3 is provided on the front end of the target board 1. The front film 3 is attached to the first positioning groove 10, so that the front film 3 can be more accurately positioned and installed on the target board 1.

[0040] Similarly, a second positioning groove 11 is provided on the rear end of the target board 1 for adapting and accommodating the backlight sticker 4. The backlight sticker 4 is attached to the second positioning groove 11 so that the backlight sticker 4 can be accurately installed on the rear end of the target board 1.

[0041] In this embodiment, the target plate 1 is further provided with two symmetrically arranged protrusions 12 on the rear edge. The protrusions 12 have connecting holes 120 on opposite sides. The support frame 2 has elastic arms 20 on both sides. The elastic arms 20 have connecting shafts 200 on their inner sides. The support frame 2 is rotatably connected to the connecting holes 120 on the protrusions 12 through the connecting shafts 200. With the cooperation of the connecting shafts 200 and the connecting holes 120, the support frame 2 can achieve the freedom of rotation.

[0042] In this embodiment, two positioning holes 121 are further provided on the protrusion 12 at different positions outside the connecting hole 120. A protrusion 201 is provided on the elastic arm 20 outside the connecting shaft 200. The protrusion 201 is adapted to and engaged with the positioning holes 121. When the support frame 2 rotates to the position of the protrusion 201 on the positioning holes 121 at different positions, the support frame 2 and the target plate 1 form an acute angle or are parallel to each other. When a flipping force is applied to the support frame 2, the protrusion 201 can disengage from the positioning hole 121 and be released from fixation. When the protrusion 201 is positioned on the positioning hole 121 at another position, different position states are switched. The purpose of designing two positioning holes 121 in this embodiment is that one can position the support frame 2 and the target plate 1 at an acute angle, in which the target plate 1 can be supported and placed on a plane, and the support frame 2 plays a stable support role at the bottom. The other can make the support frame 2 and the target plate 1 parallel, in which the target plate 1 can be suspended.

[0043] In this embodiment, a support tip 122 is further formed at the outer corner of the protrusion 12. When the support frame 2 and the target plate 1 are at an acute angle, the support tip 122 extends out of the lower side of the elastic arm 20, so that the support tip 122 and the support edge 202 at the bottom of the support frame 2 away from the elastic arm 20 form a multi-point support structure placed on the plane. When placed on the plane, the two support tips 122 and the support edge 202 at the bottom of the support frame 2 support the plane, thereby providing stable support for the target plate 1.

[0044] Secondly, the support frame 2 is provided with hanging holes 21, which can be used to suspend or hang the device.

[0045] In addition, the support frame 2 is provided with mounting holes 22 symmetrically on both sides of the hanging hole 21. Magnets are fixed in the mounting holes 22. When the target plate 1 is supported on the plane, the magnets and the iron plane generate a magnetic attraction, thereby enhancing the stability of the placement.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
