[0002] Currently, radars used for traffic speed measurement are divided into fixed and mobile types, such as Figure 1 As shown, the mobile radar speed meter 7 is inserted into the upper end of the tripod tray 21 through the tripod 2 and can be rotated. After adjusting the angle, it is fixed by screws 63, as shown in FIG. Figure 2 As shown, by adjusting the angle α (12° to 30°) between the probe direction of the radar speed meter 7 and the driving direction, a suitable detection angle is obtained and input into the radar speed meter 7. Different road conditions require different angles α.

[0003] Angle error is one of the main sources of error in speed measurement. Angle measurement and angle setting must be consistent and accurate, which is highly dependent on the experience of traffic police. Under ideal conditions, angle auxiliary lines are installed on the radar speed measurement system. In actual conditions, the parallel difference of a few degrees cannot be felt by visual observation with the naked eye. Summary of the Invention

[0042] like Figure 10 、 11As shown in , 12 and 13, the support plate 1 is equipped with a fastening mechanism 4, which fixes the angle ruler 3. Specifically, the fastening mechanism 4 includes a fixing plate 41, and the fixing plate 41 includes a plate 1 411 and a plate 2 412. The plate 2 412 is screwed and fixed to the support plate 1 through a waist-shaped hole 413, including plate 1 411 extending upward along the side of plate 2 412. The angle ruler 3 also includes a display seat 31, the upper end of the display seat 31 is higher than the top surface of the support plate 1, and the plate 1 411 is in contact with one end surface (i.e., the rear end surface) in the width direction of the display seat 31, and the other end surface (i.e., the front end surface) in the width direction of the display seat 31 is in contact with a pressing plate 1 42, and the plate 1 411 is provided with a through hole 3 414, and the pressing plate 1 42 is provided with a corresponding through hole. The plate 1 411 and the pressing plate 1 42 are tightened by bolts 45 at both ends to press the display seat 31. The pressed part of the plate 1 411 and the pressing plate 1 42 is the part of the display seat 31 that is higher than the support plate 1.

[0043] like Figure 10 、 11 As shown in Figures 12, 13, and 14, plate one 411 and pressure plate one 42 are further connected to pressure plate two 43 by screw two 48. The two ends of pressure plate two 43 are respectively connected to plate one 411 and the right end of pressure plate one 42. The end face of the display seat 31 in the longitudinal direction (i.e., the right end face) is fitted with pressure plate three 46. To be precise, a gasket 44 is provided between pressure plate three 46 and the end face of the display seat 31 in the longitudinal direction (i.e., the right end face). Pressure plate three 46 passes through pressure plate two 43 by screw one 47 and presses against pressure plate three 46 to press the display seat 31 tightly.

[0044] like Figure 3 、 8 As shown, the support plate 1 is also equipped with a bottom support assembly 6, which includes a supporting ring 2 62. The supporting ring 2 62 is a disc structure. The supporting ring 2 62 is coaxial with the support plate 1 and is located above the angle ruler 3. The bottom support assembly 6 also includes a supporting ring 1 61. Two support seats 11 are installed on the upper end of the support plate 1. The supporting ring 1 61 is installed on the upper end of the support seat 11. The supporting ring 1 61 is a circular ring structure and has a boss on each side. The boss is fastened to the upper end of the support seat 11 by screws. The upper end of the supporting ring 1 61 is threadedly connected to the supporting ring 2 62. Specifically, the supporting ring 2 62 includes a ring portion 622 located at the lower end of the supporting ring 2 62. The ring portion 622 is provided with an internal thread, and the upper end of the supporting ring 1 61 is inserted into the ring portion 622.

[0045] like Figure 3 As shown, the radar speed gun 7 is rotatably connected to the upper end of the supporting ring 2 62. The radar speed gun 7 can rotate around the center of the supporting ring 2 62. The supporting ring 2 62 is provided with a through hole 4 621. The bottom of the radar speed gun 7 is inserted into the through hole 4 621 and extends into the supporting ring 1 61. The radar speed gun 7 can be rotated around the center of the supporting ring 2 62 by manual rotation. The side wall of the supporting ring 1 61 is opened, and the screw 63 passes through the side wall of the supporting ring 1 61 to tighten the radar speed gun 7 into position.

[0046] like Figure 3 、4 As shown in , 5, 6, and 7, the movable ruler 33 is connected to a slider assembly 5 at one end away from the hinge point P, and the slider assembly 5 includes a magnet 1 53. A connecting plate 2 71 is connected to the bottom of the radar speed gun 7. The connecting plate 2 71 includes a magnet 2 72. After the movable ruler 33 rotates a certain angle, the radar speed gun 7 is manually rotated and the magnet 1 53 and the magnet 2 72 are magnetically attracted to complete the positioning. Specifically, the slider assembly 5 also includes a component 1 51 and a component 2 52 located below the component 1 51. Component 1 51 and component 2 52 pass through the angle ruler 3 and press each other tightly. The fixed ruler 32 is provided with a through hole 1 321, and the movable ruler 33 is provided with a through hole 2 331. Component 2 52 is connected to the through hole 2 331 by interference fit. Component 1 51 passes through the through hole 1 321 and is threadedly connected to be inserted into component 2 52. Component 1 51 is provided with a boss 1 511, and component 2 52 is provided with a boss 3 521. The boss 1 511 and the boss 3 521 press the angle ruler 3 up and down.

[0047] like Figure 6 As shown, component 151 is a cylindrical structure, and component 151 includes a connecting plate 1512 located at the upper end of component 151. One side of connecting plate 1512 passes through the axis of component 151, and the other side of connecting plate 1512 is connected to magnet 153. It can be understood that connecting plate 1512 is the cylindrical structure of component 151 cut into two halves from the middle and its arc surface is cut again for installing magnet 153.

[0048] like Figure 3 As shown, the second connecting plate 71 is installed below a side surface of the radar speed gun 7 in the field of view direction L of the radar speed gun probe, and the second connecting plate 71 is located in the middle of the bottom of the side surface.

[0049] like Figure 3 、 8 As shown in Figures 9 and 10, the angle ruler 3 also includes a hinge joint 34 at the upper end of the angle ruler 3. The locking or loosening between the fixed ruler 32 and the movable ruler 33 can be controlled by rotating the hinge joint 34. When the movable ruler 33 is in the loose state, it can move around the hinge point. The hinge joint 34 is connected to a wrench mechanism 8. The wrench mechanism 8 includes a rod 83. The rod 83 passes through the side wall of the support ring 61 and can rotate around the center of the hinge point P. Specifically, the side wall of the support ring 61 is provided with a groove 611. The wrench mechanism 8 also includes a fixed cylinder 82. The fixed cylinder 82 is interference-fitted with the hinge joint. 34 is connected, the inner wall of the upper end of the fixed cylinder 82 almost fits the upper end surface of the hinge joint 34, the purpose of which is to thicken the hinge joint 34, and the extension cylinder 81 is connected to the outside of the fixed cylinder 82, and the inner wall of the extension cylinder 81 is threadedly connected to the outer wall of the fixed cylinder 82. After the hinge joint 34 is thickened by the fixed cylinder 82 and then connected to the extension cylinder 81, it is not easy to fall off during the rotation process. The extension cylinder 81 is connected to the rod 83, and the connecting rod 83 is threadedly inserted into the extension cylinder 81. The rod 83 passes through the groove 611, and the rotation of the rod 83 can drive the hinge joint 34 to rotate to loosen or lock the hinge joint 34.

[0050] The angle ruler 3 is a commonly used digital angle ruler. After the relative angle between the fixed ruler 32 and the movable ruler 33 changes, the display screen on the display base 31 will display the angle value between the two. The fixed ruler 32 is fixed to the display base 31. In this embodiment, since the display base 31 is fixed by the fastening mechanism 4, the fixed ruler 32 also always remains fixed.

[0051] The method of use of this embodiment is as follows:

[0052] 1. Place the tripod 2 at the speed measurement position, remove the second support ring 62 and the slider assembly 5, rotate the rod 83 to release the movable ruler 33, and operate from above the angle ruler 3 to return the angle ruler 3 to zero.

[0053] 2. Install the second support ring 62, place the spirit level 9 on the upper end of the second support ring 62, and use the function of the spirit level 9 to alarm if it is tilted, and adjust the tripod legs 22 to make the second support ring 62 level.

[0054] Three: If Figure 16 As shown, the level meter 9 is removed and placed on the upper end of the road surface 200, and the reference light 91 emitted by the level meter 9 is used to make it parallel to the fixed ruler 32 and the driving direction of the road surface 200 respectively.

[0055] Fourth: According to the on-site conditions, the rotating rod 83 loosens the hinge joint 34, and the operator rotates the movable ruler 33 to the required angle, and the rotating rod 83 locks the movable ruler 33. The movable ruler 33 is installed with the slider assembly 5, but do not tighten it yet.

[0056] 5. Insert the radar speed gun 7 into the supporting ring 2 62 and extend it into the supporting ring 1 61. Manually rotate the radar speed gun 7 (note that the radar speed gun 7 will not move without manual rotation) so that the magnet 1 53 and the magnet 2 72 are magnetically attracted. At the same time, the connecting plate 1 512 and the connecting plate 2 71 fit together due to the magnetic force. Since the slider assembly 5 was not locked before, the connecting plate 1 512 can be rotated a certain angle under the action of the magnetic force so that the connecting plate 1 512 and the connecting plate 2 71 are completely fitted together. Tighten the screw 63 and lock the slider assembly 5.

[0057] Six: If Figure 15 As shown, the arrow direction is the field of view direction of the radar speed gun 7 probe. According to the actual adjusted angle β of the radar speed gun 7, the angle β is input into the radar speed gun 7, thereby completing the speed measurement preparation.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
