DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 4 A clamping device for testing a Beidou antenna includes a support rod 1, a base 2 for carrying the Beidou antenna, and a fixing mechanism 3 for fixing the base 2 on the support rod 1. A slide groove 4 is provided on the lower surface of the base 2, and a clamping mechanism 5 is slidably connected in the slide groove 4.

[0022] The clamping device for Beidou antenna testing in the utility model is similar to the existing antenna support clamping mechanism structure. For example, the patent with publication number CN215911580U discloses an antenna support clamping mechanism for micro base station communication equipment. The main improvement of the utility model is that by setting a movable clamping mechanism 5 and a lifting component 8, Beidou antennas of different sizes can be clamped and fixed and the installation angle can be adjusted, such as Figures 1 to 4 As shown, when the Beidou antenna test clamping device in the utility model is in use, the worker first sets the fixing mechanism 3 on the support rod 1, tightens the screw 302, and pushes the clamping plate 303 forward, and the distance between the clamping plate 303 and the fixing plate 301 is reduced, and they are fixed by squeezing each other, first driving the driver 501, and the driver 501 moves the slide bar 502 downward to move the L-shaped hook 503 downward, and the distance between the two L-shaped hooks 503 is increased, and then the Beidou antenna is placed on the base 2, and the driver 501 is retracted to reduce the distance between the two L-shaped hooks 503 until the Beidou antenna is clamped. After clamping, the angle of the Beidou antenna is adjusted by adjusting the length of the electric multi-stage telescopic rod 807 until the best test angle is found.

[0023] As shown Figure 1 or Figure 4As shown, the fixing mechanism 3 includes a fixing plate 301, a circular hole is opened on the fixing plate 301, a screw 302 is slidably connected in the circular hole, a clamping plate 303 is sleeved on one end of the screw 302 close to the nut, a first fixing block 304 is fixedly connected to the upper end of the base 2, a first groove 305 is opened on the surface of the first fixing block 304, a first rotating shaft 306 is rotatably connected in the first groove 305, a connecting rod 307 is fixedly connected to the first rotating shaft 306, and the end of the connecting rod 307 is fixedly connected to the fixing plate 301.

[0024] Specifically, the worker first sets the fixing mechanism 3 on the support rod 1 and tightens the screw 302 to push the splint 303 forward. The distance between the splint 303 and the fixing plate 301 is reduced, and they are fixed by squeezing each other and fixed to the base 2 under the action of the connecting rod 307 to ensure the stability of the base 2. The base 2 can also be rotated by the first rotating shaft 306.

[0025] like Figure 1 or Figure 4 As shown, the clamping mechanism 5 includes a driver 501 fixed to the inner wall of the slide groove 4, the front end of the driver 501 is fixedly connected to a slide rod 502, the slide rod 502 is fixedly connected to an L-shaped hook 503, and the upper end of the base 2 is also fixedly connected to an L-shaped hook 503.

[0026] Specifically, after fixing the fixing mechanism 3 and the base 2, open the driver 501, and slide the slide bar 502 downward along the slide groove 4 to move the L-shaped hook 503 downward, increase the distance between the two L-shaped hooks 503, and place the Beidou antenna on the lower L-shaped hook 503, retract the driver 501, move the slide bar 502 upward, and reduce the distance between the two L-shaped hooks 503 until the Beidou antenna is clamped and fixed.

[0027] like Figure 4 As shown, the driver 501 is a multi-stage cylinder.

[0028] Specifically, the length of the multi-stage cylinder can be adjusted according to the size of the Beidou antenna, and the Beidou antenna can be fixed by using the pulling force of the multi-stage cylinder on the sliding rod 502.

[0029] like Figure 2 As shown, a circular groove 6 is provided in the middle of the base 2 , a bolt 7 is fixedly connected in the circular groove 6 , and a lifting assembly 8 is rotatably connected between the base 2 and the fixing plate 301 .

[0030] Specifically, the bolt 7 fixed in the circular groove 6 can fix the circular Beidou antenna. After the circular Beidou antenna is tightened with the bolt 7, the angle can also be adjusted through this device.

[0031] like Figure 4As shown, the lifting assembly 8 includes a second fixed block 801 fixed under the fixed plate 301, a second groove 802 is opened on the surface of the second fixed block 801, and a second rotating shaft 803 is rotatably connected in the second groove 802, a third fixed block 804 is fixedly connected to the back side of the base 2, a third groove 805 is opened on the surface of the third fixed block 804, and a third rotating shaft 806 is rotatably connected in the third groove 805, the second rotating shaft 803 is fixedly connected to an electric multi-stage telescopic rod 807, and the output end of the electric multi-stage telescopic rod 807 is fixedly connected to the third rotating shaft 806.

[0032] Specifically, after the Beidou antenna is clamped and fixed, the electric multi-stage telescopic rod 807 is opened. As the electric multi-stage telescopic rod 807 becomes longer and longer, the base 2 is gradually moved to a horizontal state around the first rotation axis 306. During this process, the position of the electric multi-stage telescopic rod 807 will also change. The lower end point of the electric multi-stage telescopic rod 807 rotates around the second rotation axis 803, and the upper end point of the electric multi-stage telescopic rod 807 rotates around the third rotation axis 806, so that the clamped Beidou antenna can be adjusted to the optimal angle to ensure the quality of the test.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
