[0008] The movable slot is formed inside the fixed plate, the connecting plate is disposed inside the movable slot, and the end of the connecting plate is located outside the fixed plate;

[0009] The drive assembly is connected to the connecting plate and can drive the connecting plate to move in the moving slot in a direction outward from the fixed plate or inward from the fixed plate.

[0010] The rotating plate is rotatably mounted at the end of the connecting plate, and the buckle is mounted on the rotating plate; the buckle can be inserted into the connecting hole for connecting the antenna and the fixing plate in a direction from the outside of the fixing plate to the inside of the fixing plate.

[0011] Preferably, the drive assembly includes: a spring, a connecting block, and a screw;

[0012] The spring is disposed within the movable groove and located at the lower end of the connecting plate; the spring is always in a compressed state.

[0013] The connecting block is disposed in the movable groove and is fixedly connected to one side of the connecting plate. The screw is rotatably disposed on the fixed plate, and the bottom end face of the screw contacts the connecting block.

[0014] Preferably, when the screw rotates outward from the fixed plate, the connecting plate moves in the moving groove outward from the base plate via the spring;

[0015] When the screw rotates and moves inward toward the base plate, the screw drives the connecting plate to move inward toward the base plate within the moving groove via the connecting block.

[0016] Preferably, the screw and the connecting block are always in contact.

[0017] Preferably, the rotating plate is provided with a connecting post;

[0018] The rotating plate is rotatably connected to the connecting plate via the connecting column, and the connecting column is inserted into the interior of the connecting plate via a bearing.

[0019] Preferably, a base plate is fixedly connected to the lower end face of the antenna;

[0020] The base plate has a first screw hole inside, and the fixing plate has a second screw hole corresponding to the position of the first screw hole;

[0027] Preferably, the fixing plate is provided with a through hole communicating with the moving groove, and the end of the connecting plate passes through the through hole to exit the fixing plate.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] This invention places the base plate at the lower end of the antenna on the corresponding position of the fixing plate and the latch. Then, the rotating plate is rotated via the connecting column, allowing the latch to be adjusted to align with the screw hole on the base plate. The screw is then rotated inwards towards the fixing plate, pushing the connecting block and thus the connecting plate. The downward movement of the connecting plate causes the rotating plate to move downwards, allowing the latch to insert into the screw hole and fix the antenna position. To remove the antenna, the operator simply unscrews the screw, the connecting plate moves upwards, causing the latch to move upwards, and then the rotating plate rotates, causing the latch to disengage from the lower end of the base plate, thus removing the antenna. The same operation can then be used to vertically position the antenna. This allows for quick and efficient installation and fixing of the antenna, with a relatively stable position. It eliminates the need for screws to fix the antenna position, significantly improving the testing efficiency of the device and making it highly practical. Attached Figure Description

[0046] like Figures 1 to 4 As shown, this embodiment provides a radar antenna testing fixture, including a fixing plate 1, an antenna 4 is disposed on the upper end of the fixing plate 1, and a connecting mechanism 2 is disposed inside the fixing plate 1.

[0047] The connecting mechanism 2 includes a rotating plate 5, a latch 7, a connecting plate 6, a spring 9, a connecting block 10, a moving groove 8, a screw 11, and a connecting column 13. The moving groove 8 is opened inside the fixed plate 1, the connecting plate 6 is set inside the moving groove 8, the spring 9 is set at the lower end of the connecting plate 6, the connecting block 10 is fixedly connected to one side of the connecting plate 6, the bottom end face of the screw 11 is in contact with the connecting block 10, the spring 9 is always in a compressed state, the rotating plate 5 is located at the upper end of the connecting plate 6, and the latch 7 is fixedly connected to one side of the lower end face of the rotating plate 5.

[0048] The screw 11 is inserted into the inside of the fixed plate 1, and the connecting post 13 is fixedly connected to the other side of the lower end face of the rotating plate 5. The connecting post 13 is inserted into the inside of the connecting plate 6 through a bearing.

[0049] The lower end face of the antenna 4 is fixedly connected to the base plate 12, and the base plate 12 has a screw hole inside, into which the buckle 7 is inserted.

[0050] The two connecting mechanisms 2 are vertically arranged on the fixed plate 1, and the connecting plate 6 is a U-shaped plate.

[0051] Mounting plates 3 are fixedly connected to the lower ends of both sides of the fixing plate 1, and mounting holes are provided inside the mounting plates 3.

[0052] The screw 11 and the connecting block 10 never separate.

[0053] The mechanism can drive the latch 7 to insert into the screw hole to limit the position of the antenna 4. When the antenna 4 needs to be removed, the operator only needs to unscrew the screw 11, then the connecting plate 6 moves up, which in turn drives the latch 7 to move up. Then, the rotating plate 5 is rotated to drive the latch 7 to rotate and disengage from the lower end face of the base plate 12 to remove the antenna 4. The same operation is then used to set the antenna 4 vertically. The connecting mechanism 2 includes a rotating plate 5, a latch 7, a connecting plate 6, a spring 9, a connecting block 10, a moving groove 8, a screw 11, and a connecting post 13. The moving groove 8 is opened inside the fixed plate 1, the connecting plate 6 is set inside the moving groove 8, the spring 9 is set at the lower end of the connecting plate 6, the connecting block 10 is fixedly connected to one side of the connecting plate 6, the bottom end face of the screw 11 is in contact with the connecting block 10, the spring 9 is always in a compressed state, the rotating plate 5 is located at the upper end of the connecting plate 6, the latch 7 is fixedly connected to one side of the lower end face of the rotating plate 5, and the screw 11 and the connecting block 10 are always inseparable.

[0054] A specific application of this embodiment is as follows: When testing the antenna after manufacturing, it needs to be fixed onto the testing device. During this process, the antenna needs to be placed horizontally and vertically. Then, the fixing plate 1 is installed on the testing device via the mounting plate 3. When installing the antenna 4, the bottom plate 12 of the antenna 4 is placed on the fixing plate 1 at the position corresponding to the latch 7. Then, the rotating plate 5 is rotated through the connecting column 13, which adjusts the position of the latch 7 to correspond to the position of the screw hole on the bottom plate 12. Then, the rotating screw 11 is screwed inward toward the inside of the fixing plate 1, which pushes the connecting block 10, thereby pushing the position of the connecting plate 6. The movement of the connecting plate 6 causes the rotating plate 5 to move downwards, which in turn causes the latch 7 to be inserted into the screw hole to fix the position of the antenna 4. When the antenna 4 needs to be removed, the operator only needs to unscrew the screw 11, then the connecting plate 6 moves upwards, which in turn causes the latch 7 to move upwards. Then the rotating plate 5 is rotated to make the latch 7 rotate and disengage from the lower end face of the base plate 12 to remove the antenna 4. The same operation can be used to set the antenna 4 vertically, which can quickly and efficiently install and fix the antenna 4. The fixed position is relatively stable and does not require screws to fix the position of the antenna 4, which can greatly improve the testing efficiency of the device and is more practical.

[0055] This invention enables quick and efficient installation and fixing of the antenna, and the fixed position is relatively stable. It does not require screws to fix the antenna position, which can greatly improve the testing efficiency of the device and is more practical.
