Description
Technical Field
[0001] This utility model relates to the field of laser ranging module technology, and in particular to a protection device for a laser ranging module. Background Technology
[0002] A laser ranging module is a device that uses laser technology to measure distances. It calculates the distance to a target object by emitting a laser beam and receiving its reflected signal. Laser ranging modules are characterized by high precision, long-range, and non-contact measurement capabilities, and are widely used in various fields such as industrial automation, building surveying, aerospace, and environmental monitoring. The process is fast, accurate, and has a wide measurement range, from a few meters to several kilometers or even further. A typical laser ranging module includes a laser emitting module, a receiving module, a scanning module, and an information processing module. These modules work together to achieve 3D modeling and high-precision detection of the surrounding environment.
[0003] An existing protection device for a laser ranging module, Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a protection device for a laser ranging module.
[0005] This utility model is achieved by the following technical solution: a protective device for a laser ranging module, including a protective frame, a limiting groove is opened inside the protective frame, a sealing cover is inserted into the top of the protective frame, and mounting frames are fixedly connected to the left and right ends of the protective frame.
[0006] An installation rod is inserted into the inside of the mounting frame. A protective cover plate is fixedly connected to the surface of the installation rod. A second protective cover plate is inserted into the rear end of the protective frame. A handle is fixedly connected to the rear end of the second protective cover plate. A limit screw is threaded into the inside of the second protective cover plate. Fixed support plates are fixedly connected to the left and right ends of the protective frame. A connecting screw is threaded into the inside of the fixed support plate. A limit support plate is threaded into the surface of the connecting screw.
[0007] As a further improvement to the above solution, the number of the limiting slide grooves is set to four, and two slide grooves are grouped together. The four limiting slide grooves are symmetrically distributed around the protective frame, and the sealing cover is inserted into the inside of the limiting slide groove.
[0008] With the above technical solution, the four limiting grooves are symmetrically distributed around the protective frame. This symmetrical distribution makes the protective frame more uniformly stressed in all directions. When the protective device is subjected to external impact or vibration, such as during transportation or in a complex working environment, the symmetrically distributed limiting grooves can effectively disperse stress and prevent local deformation of the protective frame, thereby improving the structural stability of the entire protective device.
[0009] As a further improvement to the above solution, the number of the mounting brackets and mounting rods is set to two, and the two mounting brackets and mounting rods are symmetrically distributed on the left and right sides with the protective frame as the center.
[0010] As a further improvement to the above solution, the rear end of the first protective cover plate contacts the front surface of the protective frame, the first protective cover plate is located at the bottom of the sealing cover plate, and the front end of the second protective cover plate contacts the rear end surface of the protective frame.
[0011] Through the above technical solution, the tight cooperation between the sealing cover and the limiting slide groove forms an effective protective barrier, which can prevent harmful substances in the external environment from entering the protective frame and ensure that the laser ranging module works in a relatively clean and dry environment.
[0012] As a further improvement to the above solution, the limiting screw extends through the second protective cover plate into the interior of the protective frame, and the number of the fixed support plate and the connecting screw is set to two.
[0013] As a further improvement to the above solution, the connecting screw extends through the limiting support plate and into the interior of the fixed support plate, and the limiting support plate is slidably connected inside the protective frame.
[0014] As a further improvement to the above solution, the limiting support plate is slidably connected inside the limiting groove, and the limiting support plate is located at the bottom of the sealing cover plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention allows for the sliding removal of the sealing cover plate from the inside of the protective frame and the limiting groove. Pulling the handle removes the second protective cover plate from the rear end of the protective frame. When the laser ranging module is placed inside the protective frame, the second protective cover plate and the sealing cover plate are reset. Rotating the second protective cover plate fixes the laser ranging module inside the protective frame. Rotating the connecting screw allows for the adjustment of the height of the limiting support plate inside the limiting groove, thus limiting the laser ranging module placed inside the protective frame and increasing its stability.
[0017] This utility model protects the rear end components of the laser ranging module by setting a second protective cover. The handle at the rear end of the second protective cover facilitates the disassembly and installation of the second protective cover by the operator, and facilitates the maintenance and repair of the laser ranging module inside the protective frame. The limiting screw extends through the second protective cover into the interior of the protective frame. This setting of the limiting screw can accurately fix the position of the second protective cover on the protective frame and prevent the second protective cover from shifting during equipment operation.

[0028] An installation rod 5 is inserted into the interior of the mounting frame 4. A protective cover plate 6 is fixedly connected to the surface of the installation rod 5. A second protective cover plate 7 is inserted into the rear end of the protective frame 1. A handle 8 is fixedly connected to the rear end of the second protective cover plate 7. A limit screw 9 is threaded into the interior of the second protective cover plate 7. Fixed support plates 10 are fixedly connected to the left and right ends of the protective frame 1. A connecting screw 11 is threaded into the interior of the fixed support plate 10. A limit support plate 12 is threaded into the surface of the connecting screw 11. By pulling the sealing cover plate 3, the protective frame 1 and the limit slide groove 2 are connected from the inside. The part is slidably disassembled. Pulling the handle 8 will remove the second protective cover 7 from the rear end of the protective frame 1. When the laser ranging module is placed inside the protective frame 1, the second protective cover 7 and the sealing cover 3 are reset. The second protective cover 7 is rotated to fix the laser ranging module inside the protective frame 1. Rotating the connecting screw 11 can drive the limiting support plate 12 to adjust its position and height inside the limiting slide groove 2, which can limit the laser ranging module placed inside the protective frame 1 and increase the stability of the laser ranging module when placed inside the protective frame 1.
[0029] The number of limiting slide grooves 2 is set to four, and each pair is a group. The four limiting slide grooves 2 are symmetrically distributed with the protective frame 1 as the center, and the sealing cover plate 3 is inserted into the inside of the limiting slide groove 2.
[0030] The four limiting grooves 2 are symmetrically distributed around the protective frame 1. This symmetrical distribution makes the protective frame 1 more uniformly stressed in all directions. When the protective device is subjected to external impact or vibration, such as during transportation or in a complex working environment, the symmetrically distributed limiting grooves 2 can effectively disperse stress and prevent local deformation of the protective frame 1, thereby improving the structural stability of the entire protective device.
[0031] The number of mounting brackets 4 and mounting rods 5 is set to two, and the two mounting brackets 4 and mounting rods 5 are symmetrically distributed on the left and right sides with the protective frame 1 as the center.
[0032] The rear end of the protective cover 6 contacts the front surface of the protective frame 1. The protective cover 6 is located at the bottom of the sealing cover 3. The front of the protective cover 7 contacts the rear end surface of the protective frame 1. The protective cover 7 protects the rear end components of the laser ranging module. The handle 8 at the rear end of the protective cover 7 facilitates the disassembly and installation of the protective cover 7 by the operator, and facilitates the maintenance and repair of the laser ranging module inside the protective frame 1. The limiting screw 9 extends through the protective cover 7 into the interior of the protective frame 1. This setting of the limiting screw 9 can accurately fix the position of the protective cover 7 on the protective frame 1 and prevent the protective cover 7 from shifting during equipment operation.
[0033] The tight fit between the sealing cover plate 3 and the limiting slide groove 2 forms an effective protective barrier, which can prevent harmful substances in the external environment from entering the protective frame 1, ensuring that the laser ranging module works in a relatively clean and dry environment.
[0034] The limiting screw 9 extends through the protective cover plate 2 7 into the interior of the protective frame 1, and the number of the fixing support plate 10 and the connecting screw 11 is set to two.
[0035] The connecting screw 11 extends through the limiting support plate 12 and into the interior of the fixed support plate 10. The limiting support plate 12 is slidably connected to the interior of the protective frame 1.
[0036] The limiting support plate 12 is slidably connected inside the limiting slide groove 2, and the limiting support plate 12 is located at the bottom of the sealing cover plate 3.
[0037] The implementation principle of the protective device for a laser ranging module in this embodiment is as follows: The sealing cover 3 is slidably removed from the inside of the protective frame 1 and the limiting groove 2 by pulling it. The handle 8 is pulled to remove the second protective cover 7 from the rear end of the protective frame 1. When the laser ranging module is placed inside the protective frame 1, the second protective cover 7 and the sealing cover 3 are reset. The second protective cover 7 is rotated to fix the laser ranging module inside the protective frame 1. Rotating the connecting screw 11 can adjust the height of the limiting support plate 12 inside the limiting groove 2, thus allowing for the adjustment of the laser ranging module placed inside the protective frame 1. The distance to the module is limited, which increases the stability of the laser ranging module when it is placed inside the protective frame 1. The protective cover plate 2 7 protects the rear end of the laser ranging module. The handle 8 at the rear end of the protective cover plate 2 7 makes it easy for operators to disassemble and install the protective cover plate 2 7, which facilitates the maintenance and repair of the laser ranging module inside the protective frame 1. The limiting screw 9 extends through the protective cover plate 2 7 into the interior of the protective frame 1. This setting of the limiting screw 9 can accurately fix the position of the protective cover plate 2 7 on the protective frame 1 and prevent the protective cover plate 2 7 from shifting during equipment operation.
