[0031] The utility model provides a luminous spotting sign.

[0032] In the embodiment of the present utility model, please refer to Figures 1 to 3 The luminous target board includes:

[0033] A mounting plate 100, wherein the mounting plate 100 is provided with a mounting opening 110, and the mounting opening 110 is used for mounting the prism 600; and

[0034] The light bar 200 is disposed on the mounting plate 100 . The light bar 200 extends from the edge of the mounting opening 110 toward the edge of the mounting plate 100 .

[0035] The technical solution of the utility model is to arrange a light bar 200 on the mounting plate 100, and to open a mounting opening 110 on the mounting plate 100 adjacent to the end of the light bar 200. Thus, when visibility is low or remote measurement is performed, the light bar 200 lights up to illuminate the mounting plate 100, highlighting the position of the light-emitting target board. Moreover, under the guidance of the light bar 200, the surveyor can quickly find the mounting opening 110, that is, can quickly aim at the prism 600, thereby improving the measurement efficiency.

[0036] The light bar 200 may extend straight from the edge of the mounting opening 110 toward the edge of the mounting plate 100, or may extend in an arc or in a spiral shape. In addition, in the extension direction of the light bar 200, the light bar 200 may be arranged continuously or intermittently. As for the positions of the light bar 200 and the mounting plate 100, the light bar 200 may be arranged in contact with the surface of the mounting plate 100, or the mounting plate 100 may be provided with a mounting groove, and the light bar 200 may be installed in the mounting groove. In addition, the light bar 200 may extend between the edge of the mounting opening 110 and the edge of the mounting plate 100, or may extend from the edge of the mounting opening 110 to the edge of the mounting plate 100, and then continue to extend outward and protrude from the mounting plate 100, so that the surveyor can observe the light bar 200 on both opposite sides of the mounting plate 100, and then aim the prism 600.

[0037] In one embodiment, please refer to Figures 1 to 3 , a plurality of light bars 200 are provided, and the plurality of light bars 200 are distributed along the circumference of the mounting opening 110. It can be understood that in the present embodiment, the mounting opening 110 is provided in the middle of the mounting plate 100, and the distances from the peripheries of the mounting opening 110 to the corresponding edges of the mounting plate 100 are equal. In this way, a plurality of light bars 200 are provided along the circumference of the mounting opening 110, and the intersection of the plurality of light bars 200 is the position of the mounting opening 110, so that a crosshair can be enclosed by a plurality of light-emitting bodies, and the crosshair is provided with the mounting opening 110 to guide the surveyor to quickly find the position of the prism 600 and realize rapid aiming. Of course, the mounting opening 110 is also formed between the middle and the edge of the mounting plate 100, and the plurality of light bars 200 can be configured with different lengths according to the unequal spacing from the edge of the mounting opening 110 to the corresponding edge of the mounting plate 100. In other embodiments, only one light bar 200 can be provided, and the light bar 200 can extend in a straight line, an arc or a spiral shape.

[0038] Further, in this embodiment, please continue to refer to Figures 1 to 3The luminous sighting board includes four luminous bars 200, and the four luminous bars 200 are distributed in a cross shape. Without loss of generality, in this embodiment, the mounting plate 100 is quadrilateral, and each luminous bar 200 extends corresponding to an edge of the mounting plate 100, so that the four luminous bars 200 form an intersection, and the intersection reveals a mounting port 110. The cross luminous mark formed by the four luminous bars 200 and the distribution of the luminous bars 200 fit the shape of the mounting plate 100, thereby guiding the surveyor to quickly aim at the prism 600 at the mounting port 110. Of course, each luminous bar 200 can also extend corresponding to a corner of the mounting plate 100, or only a cross luminous mark is formed on the mounting plate 100 without adapting to the shape of the mounting plate 100. In other embodiments, the mounting plate 100 may be in the shape of a triangle, a pentagon, or a hexagon, and a light strip 200 may be provided corresponding to an edge or a corner, and a plurality of light strips 200 may be intersected at a mounting opening 110 in the middle of the mounting plate 100 to guide the user to quickly aim at the prism 600 and improve measurement efficiency.

[0039] In one embodiment, please refer to Figures 1 to 3 , the light target also includes a light beam bar 300 disposed on the mounting plate 100, the light beam bar 300 is provided with a light beam groove 310, the light bar 200 is mounted on the light beam groove 310, and the opening of the light beam groove 310 is arranged away from the mounting plate 100. It can be understood that the light beam groove 310 can guide the light emitted by the light bar 200 to only be emitted from the opening of the light beam groove 310 to form a high-brightness strip light, avoid the light emitted by the light bar 200 from diverging, so as to highlight the light target, thereby facilitating the surveyor to aim at the prism 600 according to the guidance of the strip light. Specifically, the light beam bar 300 is configured as a component mounted on the surface of the mounting plate 100, and its cross section is a U-shaped structure, wherein the shape of the light beam groove 310 is adapted to the shape of the light bar 200. Of course, in other embodiments, a strip groove can also be formed by recessing the surface of the mounting plate 100, and the light bar 200 is adapted to be installed in the strip groove.

[0040] Further, in this embodiment, please refer to Figures 1 to 3 , a light blocking member 320 is provided at the end of the light beam bar 300 facing the installation opening 110, and the end of the light bar 200 facing the installation opening 110 is opposite to the light blocking member 320. It can be understood that the light blocking member 320 is located between the light beam grooves 310, which cuts off the direct connection between the light beam grooves 310 and the prism 600, so as to prevent the light emitted by the light bar 200 from directly irradiating the prism 600, which can ensure that the surveyor can clearly observe the prism 600 or the leveling rod behind the prism 600, thereby improving the surveyor's use experience. Of course, in other embodiments, a spacer ring can also be convexly provided on the periphery of the installation opening 110 to prevent the light emitted by the light bar 200 from directly irradiating the prism 600.

[0041] For details, please refer to Figure 2 and Figure 3 The light blocking member 320 includes a main body (not shown) and a mounting flange 321 connected to the mounting plate 100. The main body covers the opening of the light beam groove 310 facing the prism 600 and is opposite to the light beam bar 300 in the axial direction of the light beam bar 300. The mounting flange 321 is connected to the end of the main body and is bent and extended relative to the main body. In this way, the mounting plate 100 provides support for the mounting flange 321, so that the main body is stably covered at the opening of the light beam groove 310 and the prism 600, ensuring the stability of the light blocking member 320, thereby preventing the light emitted by the light strip 200 from directly irradiating the prism 600 and interfering with the surveyor's aiming at the prism 600. Of course, in other embodiments, the light blocking member 320 can also be bent in the same direction at the opposite ends of the main body, and the flange is connected to the inner wall or outer wall of the two groove side walls of the light beam groove 310, so as to stably cover the opening of the light beam groove 310 and the prism 600.

[0042] In one embodiment, please refer to Figure 1 and Figure 3 The luminous sighting board also includes an indication layer 400 disposed on the mounting plate 100. The indication layer 400 is disposed corresponding to the luminous bar 200. The luminous bar 200 extends along the indication direction of the indication layer 400. The indication layer 400 is used to indicate the position of the mounting port 110. The indication layer 400 can indicate a direction. The indication layers 400 in this embodiment all indicate toward the mounting port 110 to guide the surveyor to find the prism 600. Moreover, the direction in which the luminous bar 200 extends coincides with the direction indicated by the indication layer 400. Thus, when the luminous bar 200 is lit, the indication functions of the luminous bar 200 and the indication layer 400 overlap, highlighting the position of the prism 600 on the mounting port 110, so as to guide the surveyor to quickly aim at the prism 600. Without loss of generality, the color of the indicating layer 400 is inconsistent with the color of the mounting board 100, for example: the color of the indicating layer 400 is configured to be red, the light bar 200 can emit red light, and the color of the mounting board 100 is configured to be white, so as to highlight the difference between the mounting board 100 and the indicating layer 400, thereby ensuring the double-layer guidance effect of the light bar 200 and the indicating layer 400. Specifically, the indicating layer 400 is triangular, and its corner is opposite to the edge of the mounting port 110 and is located in the middle of the edge corresponding to the mounting port 110. It should be noted that the indicating layer 400 can be a layer, a sticker or a raised structure arranged on the surface of the mounting board 100, or a component formed in the mounting board 100 and having a different color from the mounting board 100. Of course, in other embodiments, the indicating direction of the indicating layer 400 can also be set differently from the indicating direction of the light bar 200.

[0043] In one embodiment, please refer to Figure 1 and Figure 3, the light bar 200 extends outward from the edge of the mounting plate 100. It should be noted that when the light-emitting target board is used for ultra-long-distance measurement operations, the size of the light-emitting target board is difficult to be set too large, otherwise it is easy to fail to ensure the stability of the prism 600 due to excessive wind resistance. In this way, the light-emitting bar 200 is set to protrude from the edge of the mounting plate 100, and the light-emitting bar 200 has a low wind resistance effect. When the light-emitting bar 200 is lit, the recognition of the light-emitting target board can be improved, so that the surveyor can quickly find the prism 600. Among them, the part of the light-emitting bar 200 extending out of the mounting plate 100 can be observed on both opposite sides of the mounting plate 100, and the light-emitting bar 200 emits significant light to facilitate the surveyor to find the light-emitting target board. Of course, in other embodiments, the mounting plate 100 can be set in the space surrounded by the light-emitting bar 200, that is, the mounting plate 100 and the light-emitting bar 200 are alternately arranged in the circumferential direction to ensure that the user can observe the light-emitting target board on both opposite sides of the light-emitting target board.

[0044] In one embodiment, please refer to Figure 1 and Figure 3 The light strip 200 includes a light strip 210 and a protective cover 220. The light strip 210 is fixed to the mounting plate 100, and the protective cover 220 covers the light strip 210. In this way, the protective cover 220 can protect the light strip 210 and prevent foreign objects from damaging the light strip 210. At the same time, different light-emitting target cards use protective covers 220 of different colors, so that different light-emitting bodies can be selected according to the measurement environment to emit light with better recognition in the current measurement environment, so that the surveyor can quickly find the light-emitting target card. Specifically, in the present embodiment, the light strip 210 is configured as an LED light strip 210. It can be understood that the LED light strip 210 has the characteristics of small size, good flexibility, and easy installation, so that the technician can install the light strip 210 in the light beam groove 310. At the same time, the LED light strip 210 has high brightness, energy saving, environmental protection, high efficiency and stability, which improves the use time of the luminous target in low visibility conditions. In addition, the LED light strip 210 can emit light of different colors to emit the most obvious light according to different environments, so as to facilitate the surveyor to quickly align the prism 600. Of course, in other embodiments, the light strip 210 can also be configured as a fluorescent lamp, or the light strip 200 can also be directly configured as the light strip 210, or the light strip 200 includes a lamp tube, the lamp tube is installed in the light beam groove 310, and the light strip 210 is installed in the lamp tube.

[0045] In one embodiment, please refer to Figure 4 and Figure 5The luminous target also includes an adjustment member 500, which includes an adjustment frame 510 and two mounting portions 520 rotatably connected to opposite sides of the adjustment frame 510, the mounting portion 520 is fixedly connected to the mounting plate 100, the avoidance opening 511 of the adjustment frame 510 is opposite to the mounting opening 110, and the adjustment frame 510 is used to be connected to the support structure. It can be understood that the two mounting portions 520 are arranged on opposite sides of the mounting opening 110, the adjustment frame 510 and the prism 600 are arranged on opposite sides of the mounting plate 100, and the avoidance opening 511 on the adjustment frame 510 is opposite to the mounting opening 110, so as to avoid the adjustment member 500 interfering with the surveyor's observation of the level rod and other measuring tools through the prism 600. The adjustment frame 510 is fixedly connected to the support structure, the mounting portion 520 is fixedly connected to the mounting plate 100, and the adjustment frame 510 and the mounting portion 520 are rotationally connected via a rotating shaft, so that the stability of the adjustment frame 510 in the support structure is maintained, so that the mounting portion 520 and the adjustment frame 510 rotate around the rotating shaft, and the angle between the mounting plate 100 and the horizontal or vertical plane can be adjusted, so that the prism 600 can be aligned with the surveyor's measuring instrument. It should be noted that the support structure can be a sighting mark, a level ruler, etc. Of course, in other embodiments, the adjustment member 500 can also be set at a position other than the mounting opening 110 of the mounting plate 100, and is located on the side of the mounting plate 100 away from the prism 600.

[0046] Without loss of generality, a level bubble is also provided on the adjustment piece. When the surveyor adjusts the verticality of the mounting plate, he can use the level bubble to keep the mounting plate in a good vertical state, thereby adapting to the measurement environment of various slopes to ensure the accuracy and reliability of the measurement data.

[0047] The utility model also provides a prism 600 assembly, please refer to Figure 6 The prism 600 component includes a prism 600 and a light-emitting target board. The specific structure of the light-emitting target board refers to the above-mentioned embodiment. Since the prism 600 component adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0048] Please refer to Figure 6 The prism 600 is installed at the installation port 110. The prism 600 can be used in conjunction with a surveyor's rangefinder to reflect light to achieve distance measurement, or a level ruler is set behind the prism 600 to be used in conjunction with a surveyor's total station or level to achieve elevation measurement. In this way, the surveyor can quickly find the position of the light-emitting target card according to the light bar 200 and aim at the prism 600 on the installation plate 100 according to the instruction of the light bar 200, thereby improving the measurement efficiency.
