[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] In order to make the base have a structure that can be easily swung back and forth when in use, and to increase the coverage area of ​​the radar during detection, such as Figure 1-3 As shown, the millimeter-wave radar base described in the present invention includes a base 1, a motor mounting frame 2, a connecting rod 12, a connecting frame 16 and a radar mounting plate 17. The tops of the two groups of connecting frames 16 are fixed with the radar mounting plates 17 by locking bolts 18. A slot 19 is formed through the top of the radar mounting plate 17 near the center, and a mounting hole 20 is formed through the top of the radar mounting plate 17 near the edge of the slot 19.

[0024] A motor mounting bracket 2 is provided at one end of the top of the base 1, and a servo motor 5 is installed on the top of the motor mounting bracket 2 by bolts. A rotating disk 6 is connected to the outside of the output shaft of the servo motor 5, and a second extension shaft 13 is provided on one side of the rotating disk 6. Guide rails 8 are installed on both sides of the top of the base 1 away from the motor mounting bracket 2 by bolts. A guide block 9 is sleeved on the guide rail 8, and a connecting plate 10 is fixed to the top of the guide block 9 by screws. A first extension shaft 11 is welded to the top of the connecting plate 10, and circular grooves are respectively provided at both ends of the connecting rod 12, and the circular grooves are respectively sleeved on the second extension shaft 13 and the first extension shaft 11. Studs are provided on one side of the second extension shaft 13 and the first extension shaft 11, and locking nuts 14 are provided on the studs.

[0025] During use, when the servo motor 5 is working, the output shaft drives the connecting rod 12 to move, so that the first extension shaft 11 and the guide block 9 move back and forth horizontally along the guide rail 8, thereby driving the radar mounting plate 17 and the millimeter wave radar to move back and forth.

[0026] For example, Figure 1-2 As shown, the present invention further includes that a blocking piece 15 is provided on the outer side of the stud near the inner side of the locking nut 14 .

[0027] When in use, the blocking piece 15 is limited by the locking nut 14 , and the blocking piece 15 can be used to limit the position of the connecting rod 12 in the axial direction of the second extension shaft 13 and the first extension shaft 11 .

[0028] For example, Figure 2-3 As shown, the present invention further includes that a conical hollow tube 21 is welded to the bottom of the radar mounting plate 17 near the edge of the slot 19 .

[0029] When in use, the conical hollow tube 21 facilitates routing of the power supply and signal transmission cables of the millimeter wave radar.

[0030] For example, Figure 1-3 As shown, the present invention further includes: a fixing plate 3 is welded between the inner walls of the motor mounting frame 2, and a frequency converter 4 is mounted on the top of the fixing plate 3 by screws.

[0031] During use, personnel can adjust the frequency converter 4 to conveniently control the rotation speed of the servo motor 5 .

[0032] For example, Figure 1-3 As shown, the present invention also includes that the bottom of the base 1 is penetrated by slot-shaped holes near the corners.

[0033] When in use, the base 1 is conveniently fixed by passing the external bolts through the slotted holes, thereby facilitating the installation of the base.

[0034] For example, Figure 1-2 As shown, the present invention further includes that a thread groove is provided on one side of the output shaft of the guide block 9 , a decorative cover 7 is provided on one side of the rotating disk 6 , and a stud corresponding to the thread groove is provided on the decorative cover 7 .

[0035] When in use, the stud cooperates with the threaded groove to conveniently lock and fix the decorative cover 7 on one side of the rotating disk 6, and the decorative cover 7 is convenient for limiting the axial position of the rotating disk 6 on the output shaft of the servo motor 5.

[0036] When the utility model is in use, the output shaft of the servo motor 5 drives the rotating disk 6 to rotate when it is working. Since the locking nut 14 limits the connecting rod 12, and the connecting rod 12 is sleeved on the baffle 15 and the first extension shaft 11, the rotating disk 6 also drives the connecting rod 12 to move when it rotates, so that the first extension shaft 11 and the guide block 9 move back and forth horizontally along the guide rail 8. The millimeter wave radar is conveniently fixed on the top of the radar mounting plate 17 by passing the external bolt through the mounting hole 20.

[0037] The stud and the threaded groove cooperate to conveniently lock and fix the decorative cover 7 on one side of the rotating disk 6. The decorative cover 7 is convenient for limiting the axial position of the rotating disk 6 on the output shaft of the servo motor 5. The blocking piece 15 is limited by the locking nut 14. The blocking piece 15 can be used to limit the position of the connecting rod 12 in the axial direction of the second extension shaft 13 and the first extension shaft 11. The personnel can conveniently control the speed of the servo motor 5 by adjusting the inverter 4.

[0038] The guide block 9 moves back and forth along the guide rail 8, thereby driving the radar mounting plate 17 and the millimeter-wave radar to move back and forth. When in use, the radar base has a structure that can be easily swung back and forth, which is convenient for increasing the coverage area of ​​the radar during detection.
