[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides a radar installation and calibration device, including a base frame 1, a calibration mechanism 2 provided on the inner side of the base frame 1, an installation mechanism 3 fixedly provided on the upper surface of the calibration mechanism 2, and a radar device 4 provided on the upper surface of the installation mechanism 3. The calibration mechanism 2 includes a rotating rod 20, the two ends of which are fixedly connected to the inner walls of the two sides of the base frame 1 respectively. A rotating plate 22 is rotatably provided on the outer side of the rotating rod 20, and a limiting rod 24 is slidably inserted into one side of the rotating plate 22. Arc grooves 26 are provided on both sides of the base frame 1, and the inner side of the arc grooves 26 is slidably fitted with one end of the limiting rod 24. Both ends of 4 are threaded with fastening nuts 27. When using the calibration mechanism 2, first rotate the rotating plate 22 to make it rotate around the rotating rod 20 and adjust it to the required angle position. At this time, the limiting rod 24 slides in the slot 21 of the rotating plate 22 and moves along the arc grooves 26 on both sides of the base frame 1. After reaching the appropriate position, tighten the fastening nuts 27 at both ends of the limiting rod 24. Use the anti-loosening washer 23 to prevent the fastening nuts 27 from loosening, thereby stably fixing the rotating plate 22 and the mounting mechanism 3 and radar equipment 4 fixed on it at the angle position, and completing the angle calibration of the radar equipment 4.

[0018] The mounting mechanism 3 includes a mounting frame 30, the lower surface of which is fixedly connected to the upper surface of the rotating plate 22. A knob 34 is rotatably mounted on one side of the mounting frame 30, and a threaded rod 32 is fixedly mounted on one side of the knob 34. Two symmetrically distributed movable plates 35 are threaded onto the outer side of the threaded rod 32. Two positioning rods 31 are fixedly mounted on the inner walls of both sides of the mounting frame 30, and the positioning rods 31 slide against the movable plates 35. A clamping plate 36 is fixedly mounted on the upper surface of the movable plate 35, located on one side of the radar device 4. When using the mounting mechanism 3, the radar device 4 is... Place it on the mounting bracket 30, and then turn the knob 34. The knob 34 drives the threaded rod 32 to rotate. Since the threaded rod 32 is threadedly engaged with two symmetrically distributed movable plates 35, and the movable plates 35 can only move in a straight line under the constraint of the positioning rod 31, as the threaded rod 32 rotates, the two movable plates 35 will move closer or further away from each other, thereby driving the clamping plate 36 fixed on the movable plate 35 to slide along the movable groove 37 on the upper surface of the mounting bracket 30. By adjusting the distance between the two clamping plates 36, stable clamping and installation of radar equipment 4 of different sizes can be achieved.

[0019] Multiple mounting slots 25 arranged in a rectangular array on the lower surface of the base frame 1 facilitate the stable installation of the entire radar installation and calibration device on various working platforms, thereby improving the versatility and ease of installation of the device.

[0020] The anti-loosening washer 23 provided on one side of the fastening nut 27 can effectively prevent the fastening nut 27 from loosening during long-term use or when subjected to vibration, ensuring the stability and reliability of the calibration mechanism 2, and thus ensuring the angle calibration accuracy of the radar equipment 4.

[0021] The slot 21 on one side of the rotating plate 22 slides and fits with the limiting rod 24, so that the limiting rod 24 can accurately guide the rotation of the rotating plate 22 and provide stable support when fixed, thereby enhancing the structural strength and calibration accuracy of the calibration mechanism 2.

[0022] Multiple ring-shaped anti-slip textures 33 on the outer side of the knob 34 increase the friction between the hand and the knob 34, making it easier and more accurate for the operator to turn the knob 34, thus improving the ease of operation and adjustment accuracy of the mounting mechanism 3.

[0023] Two symmetrically distributed movable grooves 37 are provided on the upper surface of the mounting bracket 30, which slide and fit with the clamping plate 36, providing a stable track for the movement of the clamping plate 36 and ensuring the stability of the clamping plate 36 during movement and the clamping accuracy of the radar device 4.

[0024] Among them, radar device 4 is existing technology and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0025] Working principle: When using the calibration mechanism 2, first rotate the rotating plate 22 to make it rotate around the rotating rod 20 and adjust it to the required angle position. At this time, the limiting rod 24 slides in the slot 21 of the rotating plate 22 and moves along the arc grooves 26 on both sides of the base frame 1. After reaching the appropriate position, tighten the fastening nuts 27 at both ends of the limiting rod 24. Use the anti-loosening washer 23 to prevent the fastening nuts 27 from loosening, thereby stably fixing the rotating plate 22 and the mounting mechanism 3 and radar equipment 4 fixed on it at the angle position, and completing the angle calibration of the radar equipment 4.

[0026] When using the mounting mechanism 3, the radar device 4 is placed on the mounting frame 30, and then the knob 34 is turned. The knob 34 drives the threaded rod 32 to rotate. Since the threaded rod 32 is threadedly engaged with two symmetrically distributed movable plates 35, and the movable plates 35 can only move in a straight line under the constraint of the positioning rod 31, as the threaded rod 32 rotates, the two movable plates 35 will move closer or further away from each other, thereby causing the clamping plate 36 fixed on the movable plate 35 to slide along the movable groove 37 on the upper surface of the mounting frame 30. By adjusting the distance between the two clamping plates 36, stable clamping and installation of radar devices 4 of different sizes can be achieved.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
