Technical Field

[0001] This utility model relates to the field of antenna installation equipment technology, and in particular to a clutch mechanism for antenna adjustment. Background Technology

[0002] Currently, most antenna tuning devices on the market use gearboxes for both the top and bottom. This structure has the problem of asynchronous rotation between the top and bottom, which means the antenna cannot rotate synchronously. This makes the mechanism prone to damage and has a short service life; in severe cases, it can lead to the antenna twisting and becoming unusable. Utility Model Content

[0003] In view of the above situation, it is necessary to propose a clutch mechanism for antenna adjustment that extends service life.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clutch mechanism for antenna adjustment, comprising:

[0005] Electric motor;

[0006] A linear motion mechanism is driven by the motor, and the motor is arranged perpendicular to the direction of movement of the linear motion mechanism;

[0007] A plurality of ejector pins, wherein the ejector pins are connected to the linear motion mechanism;

[0008] A rotating block has an array of limiting holes on its outer wall. The array of limiting holes is formed by a plurality of limiting holes arranged along the rotating surface of the rotating block. Under the drive of the motor, the linear moving mechanism reciprocates to allow the ejector pin to insert into or disengage from the array of limiting holes.

[0009] Furthermore, it also includes a mounting base plate, on which the motor is fixed and the rotating block is rotatably mounted.

[0010] Furthermore, it also includes a pole-holding mechanism, which is fixedly connected to the mounting base plate.

[0011] Furthermore, the pole-holding mechanism includes a first bracket and a second bracket, as well as a screw connecting the first bracket and the second bracket. The first bracket facing the second bracket and the second bracket facing the first bracket are both provided with pole-holding slots.

[0012] Furthermore, the rod holder slot is provided with several serrations.

[0013] Furthermore, the linear motion mechanism includes a cam, a first baffle, a second baffle, and connecting rods. One end of the connecting rods is connected to the first baffle, and the other end is connected to the second baffle. The cam is connected to the output shaft of the motor. The cam intermittently abuts against the first baffle and the second baffle. The ejector pin is fixedly connected to the second baffle.

[0014] Furthermore, it also includes an antenna connector, which is fixedly connected to the rotating block.

[0015] Furthermore, the antenna connection frame includes a first frame and a second frame, which are hinged together by an adjustable screw, so that the second frame can be adjusted in the vertical direction relative to the first frame.

[0016] Furthermore, the ejector pin has a protrusion, the outer diameter of which is larger than the outer diameter of the limiting hole.

[0017] Furthermore, it also includes a guide plate, which has a guide hole for the ejector pin to pass through, and a spring is sleeved on the ejector pin, which is disposed between the protrusion and the guide plate.

[0018] The beneficial effects of this utility model are as follows: Because the motor and linear motion mechanism are perpendicularly positioned, the vertical distance between the antenna and the mast is reduced, resulting in better wind load resistance. Furthermore, the clutch can share the lateral wind load, extending the service life of the mechanism. The motor drives the linear motion mechanism to move, causing the ejector pin to insert into or disengage from the array of limiting holes on the rotating block, thus achieving the clutch function. The engagement between the ejector pin and the limiting holes is highly reliable, ensuring that the rotation of the rotating block is locked after the ejector pin is inserted.
