[0028] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0029] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0030] Reference Figure 1 and Figure 2 The present invention provides an antenna device, which is used in a synchronous clock device as an example. The antenna device is set on a wall 100 in the open-air area on the roof of a main control building, and there is a certain distance between the antenna device and the ground 200 on the roof.

[0031] Reference Figure 1 and Figure 2 The antenna device of this embodiment includes an antenna assembly 1 and a bracket assembly 2. The antenna assembly 1 includes an antenna 11 and a receiver 12 for receiving signals. A boss 13 is provided around one end of the antenna 11. The end of the antenna 11 provided with the boss 13 extends to connect with the receiver 12. The bracket assembly 2 includes a bracket body 21 and a driving member 22 provided on the bracket body 21. The bracket body 21 is provided with a fixing groove 211. The boss 13 is inserted into the fixing groove 211. The bottom of the fixing groove 211 is provided with a first avoidance hole 2111. The end of the antenna 11 away from the receiver 12 passes through the first avoidance hole 2111 and is connected to the bracket assembly 2. The antenna 11 has The receiver 12 has sufficient length. When the receiver 12 needs to be repaired, the driving member 22 can drive the boss 13 away from the fixing slot 211, that is, move it upward, and disengage the boss 13 from the notch of the fixing slot 211 and lower it. At this time, the antenna 11 is tensioned and abuts against the wall of the fixing slot 211, allowing the receiver 12 to descend to a preset height. The preset height is set to accommodate the height of the maintenance personnel for maintenance. When the maintenance is completed, by pulling the end of the antenna 11 away from the boss 13, the receiver 12 rises under the action of external force. Under the pull of the antenna 11, the boss 13 automatically inserts into the fixing slot 211. The insertion of the boss 13 into the fixing slot 211 can stabilize the antenna assembly 1 on the bracket assembly 2. The driving member 22 drives the antenna assembly 1 to descend and the antenna assembly 1 automatically resets under the pull of the antenna 11. The maintenance personnel do not need to climb to perform maintenance work, which effectively ensures the safety of the maintenance personnel when repairing the antenna assembly 1.

[0032] Specifically, refer to Figure 3 The bracket assembly 2 also includes a mounting base 24, which is installed on the wall 100. The bracket body 21 and the driving member 22 are connected to the mounting base 24. The fixing groove 211 and the driving member 22 can maintain a certain distance from the ground 200 so that the antenna assembly 1 can receive signals.

[0033] In this embodiment, referring to Figures 1 to 4 The boss 13 is conical, and the fixing groove 211 is a conical groove. The cross section of the fixing groove 211 gradually increases from the bottom of the groove toward the groove. This design can make the boss 13 more stable when inserted into the fixing groove 211, and the circular shape is conducive to the movement of the boss 13.

[0034] Specifically, refer to Figure 3 As shown, the fixing groove 211 has a first groove wall 2112 and a second groove wall 2113 disposed opposite each other. The first groove wall 2112 is closer to the wall 100, while the second groove wall 2113 is farther away from the wall 100. The first groove wall 2112 and the second groove wall 2113 are connected to form an annular groove wall. The height of the annular groove wall gradually decreases from the first groove wall 2112 to the second groove wall 2113, so that the height of the first groove wall 2112 is greater than the height of the second groove wall 2113. When the bottom of the boss 13 gradually moves and approaches the notch of the fixing groove 211, the boss 13 can be separated from the fixing groove 211 by gravity from the lower second groove wall 2113, thereby falling to a predetermined height.

[0035] Furthermore, a plurality of balls 4 are movably mounted adjacent to the slot opening of the second slot wall 2113. The balls 4 are spaced circumferentially, and the outer wall of the boss 13 abuts the balls 4. The balls 4 reduce friction between the boss 13 and the slot wall of the fixing slot 211, facilitating upward movement of the boss 13 within the fixing slot 211. Furthermore, when the receiver 12 is lowered, the antenna 11 abuts the balls 4, preventing the antenna 11 from abutting against the second slot wall 2113, thereby preventing the second slot wall 2113 from scratching the antenna 11 when the antenna 11 is pulled.

[0036] In this embodiment, the driving member 22 includes a gear 221 rotatably mounted on the bracket body 21. An opening 2114 is provided on the first groove wall 2112. A plurality of ridges (not shown) are spaced apart along the length of the boss 13 on the outer wall of the boss 13, and the ridges are arranged circumferentially. The gear 221 can pass through the opening 2114 and engage with the ridges. Rotation of the gear 221 drives the boss 13 upward to disengage from the fixing groove 211. By positioning the gear 221 on the first groove wall 2112 and opposing the ball 4, when the bottom of the boss 13 approaches the notch of the fixing groove 211, the gear 221 and the ball 4 cooperate to shift the center of gravity of the boss 13 toward the second groove wall 2113, thereby ensuring that the boss 13 descends from the second groove wall 2113.

[0037] Specifically, the driving member 22 also includes a first rotating wheel 222 arranged on the bracket body 21, and the first rotating wheel 222 is located below the gear 221. The height of the first rotating wheel 222 and the ground 200 is the same or close to a preset height, so that maintenance personnel can rotate the first rotating wheel 222 on the ground 200. The gear 221 has a rotating shaft, and the chain 223 is a closed annular steel rope. The annular steel rope is simultaneously mounted on the rotating shaft and the first rotating wheel 222, so that the gear 221 and the first rotating wheel 222 can rotate synchronously. When the receiver 12 needs to be lowered for maintenance, the rotation of the first rotating wheel 222 can be controlled to drive the gear 221 and the first rotating wheel 222 to rotate synchronously, so that the boss 13 moves upward to disengage from the fixing groove 211.

[0038] Specifically, the first rotating wheel 222 is provided with a handle 2221 so that maintenance personnel can control the rotation of the first rotating wheel 222 .

[0039] Further, refer to Figure 1 and Figure 5 The antenna device also includes a push rod assembly 3, which includes a mounting bracket 31, a push rod 32, and an elastic member 33. The mounting bracket 31 is disposed on the outer surface of the second slot wall 2113. One end of the elastic member 33 is disposed on the mounting bracket 31, and the other end is connected to the push rod 32. The second slot wall 2113 is provided with a second avoidance hole (not shown in the figure). The push rod 32 partially extends through the second avoidance hole into the fixing slot 211, thereby driving the boss 13 to engage with the gear 221. Specifically, the elastic member 33 is a spring. The end of the push rod 32 away from the elastic member 33 is provided with an arc-shaped abutment portion 321, which is capable of mating and abutting with the arc-shaped outer wall of the boss 13. When the gear 221 rotates to drive the conical boss 13 to move away from the fixed groove 211, the boss 13 and the gear 221 cannot always remain engaged. The push rod assembly 3 is set to be able to push the boss 13 to always remain engaged with the gear 221 during the movement of the boss 13, and the push rod assembly 3 pushes the bottom of the boss 13, which is conducive to the top of the boss 13 tilting toward the second groove wall 2113, ensuring that the boss 13 can move smoothly and slide off the second groove wall 2113.

[0040] Preferably, the inner sidewall of the abutment portion 321 is inclined from top to bottom, and the inner sidewall of the abutment portion 321 and the outer sidewall of the boss 13 have the same degree of inclination. When the boss 13 is inserted back into the fixing groove 211, the boss 13 can smoothly abut the abutment portion 321, compressing the push rod 32 to move toward the mounting bracket 31, ensuring that the boss 13 can be smoothly inserted into the fixing groove 211.

[0041] Furthermore, the bracket assembly 2 also includes a second rotating wheel 23 coaxially arranged with the first rotating wheel 222. The end of the antenna 11 away from the boss 13 passes through the first avoidance hole 2111 and is fixed to the second rotating wheel 23, with a portion of the antenna 11 wound and stored on the second rotating wheel 23. When the first rotating wheel 222 rotates, the gear 221 rotates synchronously, causing the boss 13 to move upward and disengage from the fixing slot 211. At the same time, the second rotating wheel 23 rotates synchronously, gradually loosening the antenna 11, allowing the boss 13 to move upward smoothly. When maintenance is complete, the first rotating wheel 222 rotates in the opposite direction to cause the second rotating wheel 23 to rotate in the opposite direction. The second rotating wheel 23 can then wind up the antenna 11, tightening the antenna 11 to raise the boss 13 and the receiver 12, and the boss 13 is inserted into the fixing slot 211.

[0042] Preferably, a protective layer (not shown) is provided on the outer wall of antenna 11. In this embodiment, the protective layer is a steel rope wrapped around the outer side of antenna 11. Providing a protective layer on the outer wall of antenna 11 increases the tensile strength of antenna 11, making it less likely to break due to frequent pulling.

[0043] In this embodiment, referring to Figure 1 and Figure 2 A shield 5 is also provided on top of the mounting base 24. This shield 5 is positioned above the antenna assembly 1 and is provided with a heat-insulating layer and a waterproof layer (not shown). The shield 5 covers the antenna assembly 1. Due to the receiver 12 being exposed to sunlight and rain for a long time, the circuit boards within the receiver 12 are susceptible to aging or moisture damage. By providing the shield 5 to shield the antenna assembly 1, the antenna assembly 1 is protected from sunlight and rain, thereby reducing the failure rate of the antenna assembly 1 and increasing its lifespan.

[0044] Preferably, the interfaces of the antenna assembly 1 are subjected to moisture-proof sealing treatment to further reduce the failure rate of the antenna assembly 1 .
