Description

Technical Field

[0001] This utility model belongs to the field of antenna technology, specifically relating to a portable ground umbrella antenna manual deployment mechanism. Background Technology

[0002] Portable ground umbrella antennas require lightweight construction, necessitating manual deployment. Current manual deployment mechanisms for portable ground umbrella antennas utilize manually driven crank-slider or damped hinge mechanisms to rotate ribs, thereby enabling the antenna to fold and unfold. Crank-slider mechanisms are somewhat bulky and space-consuming, resulting in limited usable internal space. While damped hinge mechanisms overcome the drawbacks of crank-slider mechanisms, they require a high damping torque on the hinge, which is difficult to control.

[0003] A patent document with publication number CN218636412U discloses a "manual deployment mechanism for a ground umbrella antenna", which includes a basin-shaped base, damping hinges, rib flanges, ribs, and a flexible metal mesh. The ribs are mounted on the rib flanges, and adjacent ribs are connected to each other through the flexible metal mesh. A plurality of damping hinges are evenly distributed in a circular shape relative to the basin-shaped base, with one side connected to the basin-shaped base and the other side of the damping hinges fixed to the rib flanges to prevent the ribs from rotating relative to the basin-shaped base only under the action of gravity.

[0004] When the umbrella antenna is deployed, the above-mentioned device limits the rib by cooperating with the damping hinge and the rib flange. In the long-term use, this method can easily put a great burden on the damping hinge, causing the rib to become loose. Therefore, a more suitable support structure needs to be designed to ensure the stability of the rib. Utility Model Content

[0005] The purpose of this invention is to provide a portable manual deployment mechanism for a ground umbrella antenna. This invention has a simple structure and operation, and is equipped with a support connection structure. When the umbrella antenna is in the deployed state, the ribs can be stably supported by tightening the locking screws, which avoids the ribs from loosening due to long-term use. It is durable and practical.

[0006] The technical solution adopted by this utility model is a portable ground umbrella antenna manual deployment mechanism, including a support cylinder, ribs, support rod mounting seats, pins, flexible metal mesh, and a support connection structure. Several support rod mounting seats are circumferentially fixed on the top surface of the support cylinder. The ribs correspond one-to-one with the support rod mounting seats and are rotatably connected by pins so that the ribs can be deployed outward or retracted inward relative to the support cylinder. The flexible metal mesh is installed on the ribs. The outer side of the ribs is connected to the outer side wall of the support cylinder through the support connection structure, which provides stable support for the ribs in the deployed state.

[0007] Furthermore, the support connection structure includes a sliding rod, a central shaft, and a locking screw. One end of the sliding rod is rotatably connected to the outer side of the rib via the central shaft, and the other end of the sliding rod is connected to the outer wall of the support cylinder via a tightenable locking screw. The locking screw is movably inserted into the sliding groove of the sliding rod.

[0008] The beneficial effects of this utility model are as follows:

[0009] This utility model has a simple structure and operation. It is equipped with a support connection structure. When the umbrella antenna is in the unfolded state, the ribs can be stably supported by tightening the locking screws, which can prevent the ribs from loosening due to long-term use. It is durable and practical. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Please refer to Figure 1 , Figure 2 , Figure 3 As shown, the portable ground umbrella antenna manual deployment mechanism provided by this utility model includes a support cylinder 1, ribs 2, support rod mounting bases 4, pins 6, flexible metal mesh 5, and a support connection structure. Several support rod mounting bases 4 are circumferentially fixed on the top surface of the support cylinder 1. The ribs 2 correspond one-to-one with the support rod mounting bases 4 and are rotatably connected by pins 6 so that the ribs 2 can be deployed outward or retracted inward relative to the support cylinder 1. The flexible metal mesh 5 is installed on the ribs 2. The outer side of the ribs 2 is connected to the outer side wall of the support cylinder 1 through the support connection structure. The support connection structure is used to provide stable support for the ribs 2 in the deployed state.

[0016] The support connection structure includes a sliding rod 3, a central shaft 7, and a locking screw 8. One end of the sliding rod 3 is rotatably connected to the outer side of the rib 2 via the central shaft 7, and the other end of the sliding rod 3 is connected to the outer side wall of the support cylinder 1 via a tightenable locking screw 8. The locking screw 8 is movably inserted into the sliding groove of the sliding rod 3.

[0017] The manual deployment mechanism for the portable ground umbrella antenna of this invention unfolds as follows:

[0018] First, slightly loosen the locking screw 8 on the slide bar 3. Then, manually rotate the rib 2 outwards. The slide bar 3 will slide down along the locking screw 8. When the rib 2 stops rotating at a certain angle, tighten the locking screw 8. Finally, rotate each rib outwards at a certain angle. As the rotation angle gradually increases, the antenna deployment is finally completed.

[0019] The manual deployment and retraction process of the portable ground umbrella antenna of this utility model is as follows:

[0020] First, slightly loosen the locking screw 8 on the slide bar 3. Then, manually rotate the rib 2 inward. The slide bar 3 will slide upward along the locking screw 8. When the rib 2 stops rotating at a certain angle, tighten the locking screw 8. Finally, rotate each rib inward at a certain angle. As the rotation angle gradually increases, the antenna retraction action is finally completed.
