[0024] See also Figure 1-Figure 7 , the utility model provides embodiments:

[0025] A radio and television network coverage assembly tower, comprising a base 1, a tower section 2 is installed on the top of the base 1, a switch box 7 is arranged on the tower section 2, a tower top 4 is installed on the top of the tower section 2, a fixed ring 5 is fixedly sleeved on the tower section 2, a mobile ring 6 located below the fixed ring 5 is slidably sleeved on the tower section 2, a plurality of upper T-shaped grooves 9 are opened on the bottom outer wall of the fixed ring 5, a plurality of lower T-shaped grooves 8 are opened on the top outer wall of the mobile ring 6, the plurality of lower T-shaped grooves 8 respectively correspond to the positions of the plurality of upper T-shaped grooves 9 in the vertical direction, and T-shaped grooves 8 and upper T-shaped grooves 9 corresponding to each other are slidably installed in the lower T-shaped grooves 8 and the upper T-shaped grooves 9. T-shaped slider 30, the top and bottom of the T-shaped slider 30 are respectively in contact with the inner walls of the upper T-shaped groove 9 and the lower T-shaped groove 8 which are away from each other. A plurality of signal transceivers 3 are arranged on one side of the tower top 4, and the sides of the plurality of T-shaped sliders 30 respectively correspond to the sides of the plurality of signal transceivers 3 one by one and are fixedly connected. A plurality of fixing mechanisms are installed on the fixing ring 5, and the fixing mechanisms are used to fix the position of the T-shaped slider 30. A plurality of pressing mechanisms are installed on the fixing ring 5, and the pressing mechanisms are used to push the T-shaped slider 30 out of the upper T-shaped groove 9. A reeling mechanism for retracting and releasing the movable ring 6 is installed on the tower section 2.

[0026] With the above structure: when it is necessary to inspect and repair some signal transceivers 3, the fixing mechanisms on some T-shaped sliders 30 are released, so that some T-shaped sliders 30 are separated from the fixed rings 5, and then the movable ring 6 can be released to the maintenance personnel through the unwinding mechanism. When the movable ring 6 moves, the setting of the pressing mechanism ensures that when the T-shaped slider 30 is separated from the upper T-shaped groove 9 on the fixed ring 5, the T-shaped slider 30 is always located on the lower T-shaped groove 8, so that some signal transceivers 3 can be inspected separately.

[0027] like Figure 4 , Figure 5 and Figure 7 As shown, the fixing mechanism includes a cavity 22 opened on the fixing ring 5, sliders 20 are slidably mounted on the inner walls of both sides of the cavity 22, connecting rods 23 are fixedly mounted on the sides of the two sliders 20 close to each other, iron blocks 24 are fixedly mounted on the sides of the connecting rods 23, and an electromagnet 18 is fixedly mounted on the inner wall of the bottom side of the connecting rod 23. The positions of the electromagnet 18 and the iron block 24 correspond to each other, and a return spring 21 is fixedly mounted on the side of the iron block 24 away from the electromagnet 18 and the inner wall of the cavity 22 away from the electromagnet 18. Two plug rods 13 are fixedly installed on the side of the connecting rod 23, and two slots 29 are provided on the side of the T-shaped slider 30 away from the signal transceiver 3, and one end of the two plug rods 13 extends into the two slots 29 respectively; two round holes are provided on the inner wall of the upper T-shaped slot 9, and the two round holes are connected to the cavity 22, and one end of the two plug rods 13 passes through the two round holes respectively; sliding grooves 19 are provided on the inner walls of both sides of the cavity 22, and the sides of the two sliders 20 away from each other are slidably installed in the two sliding grooves 19 respectively. The electromagnet 18 generates suction force to adsorb the corresponding iron block 24, thereby driving the connecting rod 23, the two sliders 20 and the two plug rods 13 to move, and the reset spring 21 is deformed, so that the two plug rods 13 are moved out of the two slots 29 respectively, thereby releasing the fixation of the T-shaped slider 30.

[0028] like Figure 2 , Figure 3 and Figure 5As shown, the pressing mechanism includes a pressing groove 10 opened on the side of the fixing ring 5, and a pressing hole 17 connected to the upper T-shaped groove 9 is opened on the bottom inner wall of the lower pressing groove 10. A pressing rod 16 is slidably installed in the pressing hole 17. The top end of the pressing rod 16 extends into the lower pressing groove 10 and is fixedly installed with a pressing block 14. The bottom end of the pressing rod 16 contacts the top of the T-shaped slider 30. An extrusion spring 15 is sleeved on the pressing rod 16. The top and bottom ends of the extrusion spring 15 are respectively fixedly installed on the bottom of the pressing block 14 and the bottom inner wall of the lower pressing groove 10. Since the extrusion spring 15 is in a deformed state, a pulling force is generated, which causes the pressure block 14 and the pressure rod 16 to move downward. When the fixed ring 5 is separated from the movable ring 6, the T-shaped slider 30 that has lost its limit will be squeezed by the pressure rod 16, so that the T-shaped slider 30 will move downward with the movable ring 6 until the T-shaped slider 30 moves out of the upper T-shaped groove 9. By setting the pressure rod 16, the T-shaped slider 30 is prevented from being stuck on the upper T-shaped groove 9, ensuring that the T-shaped slider 30 is located on the lower T-shaped groove 8 when disengaged.

[0029] like Figure 6 As shown, a motor 25 is fixedly installed in the tower section 2, a lower reel 26 is fixedly installed on the output shaft of the motor 25, an upper reel 27 is fixedly installed on the top of the lower reel 26, ropes are wound around the upper reel 27 and the lower reel 26, two pulley holes are provided on the inner wall of the tower section 2, pulleys 28 are rotatably installed in the two pulley holes, the ends of the two ropes away from each other are respectively passed around the two pulleys 28 and fixedly installed on the inner wall of the moving ring 6, a switch group is installed on the inner side of the switch box 7, the switch group is connected to the motor 25 and a plurality of electromagnets 18 through electric wires, this is the prior art, and reference can be made to a network coverage assembly tower with announcement number CN219387414U in the prior art. Starting the motor 25 causes the lower reel 26 and the upper reel 27 to release the rope, and the movable ring 6 moves downward due to gravity, so that the signal transceiver 3 can be moved downward to the maintenance personnel for easy maintenance. After the maintenance is completed, the output shaft of the motor 25 is reversed to cause the lower reel 26 and the upper reel 27 to reel in the rope, thereby restoring the signal transceiver 3 to its original state.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the outer side of the tower section 2 is provided with a plurality of guide grooves 12, and guide blocks 11 are slidably installed in the plurality of guide grooves 12. The plurality of guide blocks 11 are fixedly installed on the inner wall of the moving ring 6 away from the side of the tower section 2. By setting the guide blocks 11 and the guide grooves 12, it can be ensured that the T-shaped slider 30 will correspond to the upper T-shaped groove 9.

[0031] The working principle of the utility model is:

[0032] When it is necessary to inspect some signal transceivers 3, the electromagnet 18 on the upper part of the signal transceiver 3 to be inspected is started to generate suction, and the corresponding iron block 24 is adsorbed, thereby driving the connecting rod 23, the two sliders 20 and the two plug rods 13 to move, and the reset spring 21 is deformed, so that the two plug rods 13 are moved out of the two slots 29 respectively. At this time, the corresponding T-shaped slider 30 loses its limit, and then the motor 25 is started to release the rope from the lower reel 26 and the upper reel 27. The mobile ring 6 moves downward due to gravity. At this time, the extrusion spring 15 is in a deformed state, so The rebound force is generated so that the pressure block 14 and the pressure rod 16 have the force to move downward. When the fixed ring 5 is separated from the movable ring 6, the T-shaped slider 30 that loses the limit will be squeezed by the pressure rod 16, so that the T-shaped slider 30 will move downward with the movable ring 6 until the T-shaped slider 30 moves out of the upper T-shaped groove 9. The setting of the pressure rod 16 prevents the T-shaped slider 30 from being stuck on the upper T-shaped groove 9, and ensures that the T-shaped slider 30 is located on the lower T-shaped groove 8 when it is disengaged. The T-shaped slider 30 is located on the lower T-shaped groove 8, so that the signal transceiver 3 can be lowered to the maintenance personnel together with the movable ring 6;

[0033] After the inspection is completed, the output shaft of the motor 25 is reversed so that the lower reel 26 and the upper reel 27 reel up the rope, thereby moving the T-shaped slider 30 and the signal transceiver 3 upward. By setting the guide block 11 and the guide groove 12, it can be ensured that the T-shaped slider 30 will correspond to the upper T-shaped groove 9. When the T-shaped slider 30 is fully inserted into the upper T-shaped groove 9, the pressure block 14 and the pressure rod 16 return to their original state, and the extrusion spring 15 is deformed. Then, by closing the electromagnet 18, the two insertion rods 13 are respectively inserted into the two slots 29 under the action of the reset spring 21 to complete the limit.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
