Description

Technical Field

[0001] This utility model relates to the field of engineering measurement technology, and in particular to a laser target device for engineering measurement. Background Technology

[0002] Laser measurement technology is the cornerstone of modern engineering construction. Equipment such as laser levels and laser line projectors provide intuitive and efficient benchmarks for construction layout, equipment installation, and quality inspection by emitting visible laser beams. As a key terminal of this technology system, laser targets undertake the core functions of receiving, locating, and accurately displaying laser spots or laser surfaces. Their performance directly affects the efficiency and accuracy of measurement work.

[0003] The main structure of a laser target is usually a flat plate made of transparent acrylic or glass. Its working surface is printed with a precise scale grid. Operators usually store the laser target together with other field tools for easy carrying. Traditional laser targets lack protective functions. During storage and carrying, its working surface is easily scratched and damaged by other tools, affecting the measurement accuracy. Although some laser targets are equipped with a split storage shell, in complex working environments, the split storage shell is easily lost due to management oversight or a chaotic working environment.

[0004] Therefore, to address the above problems, a laser target device for engineering measurement can be designed. By integrating the laser target into a matching outer shell, the working surface of the target plate can be unfolded outward to realize the measurement function in the working state. In the non-working state, the working surface can be completely stored inside the outer shell by flipping it over. The physical protective barrier constructed by the outer shell provides effective protection, solving the problems of lack of protection and loss of the outer shell in the storage and carrying process of traditional laser targets. Utility Model Content

[0005] To overcome the lack of protective features in traditional laser targets, which make their working surfaces easily scratched and damaged by other tools during storage and transport, affecting measurement accuracy, although some laser targets are equipped with separate storage shells, these shells are prone to loss due to management oversights or chaotic working environments in complex operating environments.

[0006] The technical solution of this utility model is as follows: a laser target device for engineering measurement, including a target plate and an outer shell, and a sliding groove opened in the inner cavity side wall of the outer shell. An assembly strip is slidably connected inside the sliding groove. A handle is fixedly installed at the upper end of the assembly strip. The target plate is rotatably connected to the upper end of the assembly strip. The lower end face of the target plate contacts the handle. The two sides of the target plate match the shape of the sliding groove.

[0007] Preferably, the target plate is installed using an assembly strip. When the target is not in use, the working surface of the target plate faces the inner cavity of the outer shell. The physical protective barrier constructed by the outer shell effectively protects the working surface of the target plate, preventing damage to the working surface of the target plate during storage and transportation. When working, use the handle to push the assembly strip upward so that the target plate is completely separated from the outer shell. Then rotate the target plate so that its working surface faces outward and aligns with the slide groove. Then reset the target plate and assemble the outer shell in the appropriate position to start working.

[0008] Preferably, a top cover is hinged to the upper end of the outer casing, an elastic bracket is fixedly installed on the front side of the top cover, and a protrusion is fixedly installed on the front side of the outer casing at a position corresponding to the elastic bracket.

[0009] Preferably, the outer casing has a number of cleaning rollers arranged linearly along the axis rotatably connected inside, and the surface of the cleaning rollers is in contact with the surface of the target plate.

[0010] Preferably, a mounting bracket is provided on the periphery of the outer casing, and a connecting shaft is rotatably connected inside the mounting bracket. The connecting shaft is fixedly connected to the outer casing, and the connection between the connecting shaft and the mounting bracket is damped.

[0011] Preferably, a connecting sleeve is fixedly installed at the lower end of the mounting bracket, a connecting rod is connected to the internal thread of the connecting sleeve, and a fixing plate is fixedly installed at the lower end of the connecting rod.

[0012] Preferably, a magnet is embedded in the lower end of the fixing plate, and a suction cup is provided at the lower end of the fixing plate.

[0013] Preferably, a foam sheet is provided at the lower end of the fixing plate, and several pre-drilled holes are provided on the surface of the fixing plate.

[0014] The beneficial effects of this utility model are: The target plate is movably assembled inside the outer shell using an assembly strip. When the target is not in use, the working surface of the target plate faces the inner cavity of the outer shell. The physical protective barrier constructed by the outer shell effectively protects the working surface of the target plate, preventing damage to the working surface during storage and transport. When working, use the handle to push the assembly strip upwards to completely separate the target plate from the outer shell. Then rotate the target plate so that its working surface faces outwards and aligns with the slide groove. Then reset the target plate and assemble the outer shell in the appropriate position to begin work. During the operation, the target plate does not need to be separated from the outer shell, preventing the outer shell from being lost in a messy work environment. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1 Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a laser target device for engineering measurement, comprising a target plate 1 and a housing 2, and a groove 201 formed in the inner wall of the housing 2. An assembly strip 3 is slidably connected inside the groove 201, and a handle 301 is fixedly installed at the upper end of the assembly strip 3. The target plate 1 is rotatably connected to the upper end of the assembly strip 3, and the lower end face of the target plate 1 contacts the handle 301. The two sides of the target plate 1 match the shape of the groove 201. The target plate 1 is installed by the assembly strip 3. When the target is not in use, the working surface of the target plate 1 faces the inner cavity of the housing 2. The physical protective barrier constructed by the housing 2 effectively protects the working surface of the target plate 1, which can effectively prevent damage to the working surface of the target plate 1 during storage and carrying. When working, the assembly strip 3 is pushed upward by the handle 301 so that the target plate 1 is completely separated from the housing 2. Then the target plate 1 is rotated so that its working surface faces outward and is aligned with the groove 201. The target plate 1 is then reset, and the housing 2 is assembled in the appropriate position to start working.

[0018] Please see Figure 2 and Figure 4In this embodiment, a top cover 6 is hinged to the upper end of the outer shell 2. An elastic bracket 601 is fixedly installed on the front side of the top cover 6, and a protrusion 602 is fixedly installed on the front side of the outer shell 2 at a position corresponding to the elastic bracket 601. The top cover 6 can limit the upper end of the target plate 1, and the protrusion 602, in conjunction with the elastic bracket 601, can fix the closed top cover 6. Several axially linearly arranged cleaning rollers 4 are rotatably connected inside the outer shell 2, and the surface of the cleaning rollers 4 is in contact with the surface of the target plate 1. The cleaning rollers 4 can clean the working surface of the target plate 1 during the process of the target plate 1 being pulled out or put back into the outer shell 2, so as to ensure the working accuracy of the target plate 1.

[0019] Please see Figure 5 In this embodiment, a mounting frame 5 is provided on the periphery of the outer shell 2. A connecting shaft 501 is rotatably connected inside the mounting frame 5. The connecting shaft 501 is fixedly connected to the outer shell 2, and the connection between the connecting shaft 501 and the mounting frame 5 is damped. The outer shell 2 is installed by the mounting frame 5 in conjunction with the connecting shaft 501, so that the outer shell 2 can rotate freely and hover along the connecting shaft 501, which facilitates the adjustment of the angle of the target plate 1. A connecting sleeve 7 is fixedly installed at the lower end of the mounting frame 5. A connecting rod 8 is threaded inside the connecting sleeve 7. A fixing plate 9 is fixedly installed at the lower end of the connecting rod 8. A magnet plate 901 is embedded at the lower end of the fixing plate 9, and a suction cup 902 is provided at the lower end of the fixing plate 9. The fixing plate 9 is detachably assembled to the lower end of the mounting frame 5 by the connecting rod 8 in conjunction with the connecting sleeve 7. The entire device can be stably fixed to the surface of a smooth or ferromagnetic substrate by the suction cup 902 and the magnet plate 901.

[0020] Example 2 Please see Figure 6 The difference from Embodiment 1 is that, in this embodiment, a foam film 903 is provided at the lower end of the fixing plate 9, and a number of reserved holes 904 are opened on the surface of the fixing plate 9. When the assembly surface is not smooth or does not have ferromagnetism, the overall device can be assembled by conventional fasteners by installing the fixing plate 9 with reserved holes 904, or it can be bonded by foam film 903.

[0021] During operation, the outer shell 2 is installed in a suitable position using the fixing plate 9 and the mounting bracket 5. The top cover 6 is opened, and the assembly strip 3 is pushed upward using the handle 301 to completely separate the target plate 1 from the outer shell 2. Then, the target plate 1 is rotated so that its working surface faces outward and aligns with the slide groove 201. The target plate 1 is then reset so that its working surface faces the outside of the outer shell 2. The top cover 6 is then closed, and the top cover 6 is locked using the elastic clip 601 and the protrusion 602 to fix the target plate 1. The angle of the target plate 1 can be adjusted by rotating the outer shell 2 along the connecting shaft 501. After the operation is completed, repeat the above steps to pull out the target plate 1 and rotate it so that the working surface of the target plate 1 faces the inside of the outer shell 2. Then close the top cover 6 to fix the target plate 1. The physical protective barrier constructed by the outer shell 2 effectively protects the working surface of the target plate 1, which can effectively prevent the working surface of the target plate 1 from being damaged during storage and carrying. During the process of pulling out or re-inserting the target plate 1 into the outer shell 2, the cleaning roller 4 will clean the working surface of the target plate 1 to ensure the working accuracy of the target plate 1. During operation, the target plate 1 does not need to be separated from the outer shell 2, effectively avoiding the loss of the outer shell 2 in complex working environments.

[0022] Through the above steps, the assembly strip 3 is used to install the target plate 1. When the target is not in use, the working surface of the target plate 1 faces the inner cavity of the outer shell 2. The physical protective barrier constructed by the outer shell 2 effectively protects the working surface of the target plate 1, which can effectively prevent damage to the working surface of the target plate 1 during storage and transportation. When working, the assembly strip 3 is pushed upward with the handle 301 to completely separate the target plate 1 from the outer shell 2. Then, the target plate 1 is rotated so that its working surface faces outward and aligns with the slide groove 201. The target plate 1 is then reset and the work can begin. During the operation, the target plate 1 does not need to be separated from the outer shell 2, preventing the outer shell 2 from being lost in a messy work environment. This solves the problem that traditional laser targets lack protective functions. During storage and transportation, their working surfaces are easily scratched and damaged by other tools, affecting measurement accuracy. Although some laser targets are equipped with separate storage shells, in complex working environments, separate storage shells are easily lost due to management oversights or a chaotic working environment.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
