Its function is to convert the base station's electrical signals into electromagnetic wave signals and send them to the terminal, and to receive the electromagnetic wave signals sent by the terminal and convert them into electrical signals and send them to the base station for decoding to obtain information. It is usually installed in high places such as high towers, buildings or mountain tops to ensure the stability and reliability of signal transmission.

[0003] In the existing technology, the base station antenna is usually installed on a mounting pole at a high place, and the connection between the base station and the mounting pole is only connected with screws and nuts. Because there is no building to block the wind, the wind is strong, and the nuts exposed to the outside cannot resist the wind pressure and wind shear force (wind pressure refers to the force exerted by the wind on the surface of an object, and wind shear force refers to the difference in force exerted by the wind on different parts of an object) from the wind for a long time, so they fall off, causing the base station antenna to fall off, causing damage to the base station antenna, affecting communications or causing safety accidents.

[0004] In summary, the connection between the base station and the mounting pole cannot be connected only by screws and nuts, so the utility model provides a wind-resistant and anti-falling mounting structure for the base station antenna to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model drives the first limit column and the second limit column by rotating the knob, and because the first limit column and the second limit column are against the inclined block, the first special-shaped sliding block and the second special-shaped sliding block are allowed to slide and rebound in the baffle plate under the action of the spring, and after the first limit column and the second limit column continue to move and against the baffle plate, they drive the baffle plate to move, and the baffle plate drives the connecting plate through the chassis and the connecting column, so that the first connecting member and the second connecting member slide in the curved groove, thereby realizing the contraction or expansion of the first fixed block and the second fixed block, and because the first pawl and the second pawl are meshedly connected with the first ratchet and the second ratchet, the first fixed block and the second fixed block cannot be locked or expanded by themselves, thereby realizing the locking function.

[0026] The rotation of the connecting plate 1 drives the first connecting member 2 and the second connecting member 5 to slide in the curved groove 9, thereby driving the first fixing block 3 and the second fixing block 6 to be locked and unfolded.

[0027] As a specific implementation of the utility model, screw holes 11 are provided at both ends of the first connecting block 4 and the second connecting block 7. After the first fixing block 3 and the second fixing block 6 are locked, screws can be used to fix them for safety.

[0028] As a specific implementation of the utility model, the first fixing block 3 and the second fixing block 6 are provided with fixing grooves 12 adapted to the cylinder, which have a better locking effect when facing the cylindrical installation rod.

[0029] As a specific embodiment of the present utility model, the locking structure 10 includes a chassis 101, a column 102 is arranged in the middle of the chassis 101, and blocks 103 are arranged on the surface of the chassis 101. The blocks 103 are arranged in groups of two on both sides of the column 102, and an appropriate space is left between each group of blocks 103. The two groups of blocks 103 are movably connected to the first special-shaped slider 104 and the second special-shaped slider 105. One end of the first special-shaped slider 104 and the second special-shaped slider 105 is against the spring 106, and the spring 106 is against the column 102. The other ends of the first special-shaped slider 104 and the second special-shaped slider 105 are provided with a first pawl 107 and a second pawl 108, and the first pawl 107 and the second pawl 108 are meshed and connected with a first ratchet 109 and the second ratchet 110, the column 102 is movably connected with a knob 112 through a connecting shaft 111, one end of the knob 112 is fixedly connected to a first limiting column 113 and a second limiting column 114, the first special-shaped slider 104 and the second special-shaped slider 105 are provided with a groove 115 adapted to the first limiting column 113 and the second limiting column 114, one end of the first special-shaped slider 104 and the second special-shaped slider 105 is provided with an inclined block 116, the first limiting column 113 and the second limiting column 114 are abutted against the inclined block 116 through the groove 115, one end of the chassis 101 is fixedly connected with a connecting column 8, the first ratchet 109 and the second ratchet 110 are sequentially arranged on the other end of the chassis 101, and the tooth grooves of the first ratchet 109 and the second ratchet 110 are opposite.

[0030] Rotate the knob 112 counterclockwise, the knob 112 drives the No. 1 limiting column 113 and the No. 2 limiting column 114 to move in the baffle 103. When the No. 1 limiting column 113 contacts the baffle 103, it drives the baffle 103 to move. The baffle 103 drives the first special-shaped slider 104 inside it to move. The first special-shaped slider drives the first pawl to move on the first ratchet under the action of the spring 106. At the same time, the No. 2 limiting column 114 first contacts the inclined block 116 of the second special-shaped slider 105. Under the action of the inclined surface and the spring 106, the No. 2 limiting block contracts the second pawl 108, so that the knob 112 rotates normally. At this time, the baffle 103 drives the chassis 101 rotates, the chassis 101 drives the connecting column 8 to rotate, and the connecting column 8 drives the connecting disk 1 to rotate, so that the first connecting member 2 and the second connecting member 5 slide counterclockwise in the curved groove 9, thereby realizing the contraction of the first fixing block 3 and the second fixing block 5. When the base station antenna is contracted to be firmly connected to the mounting rod, the counterclockwise rotation of the knob 112 is stopped, because the cooperation of the first pawl 107, the first ratchet 109, the second pawl 108 and the second ratchet makes it impossible for the connecting disk 1 itself to rotate clockwise or counterclockwise, thereby achieving a self-locking effect, and then the first connecting member 2 and the second connecting member 5 can be connected by screws through the screw holes 11 to play a safety role.

[0031] Rotate the knob 112 clockwise, the knob 112 drives the second pawl 108 to move on the second ratchet 110, and at the same time the second limiting column 114 first contacts the inclined block 116 of the second special-shaped slider 105. Under the action of the inclined surface and the spring 106, the No. 1 limiting block contracts the first pawl 107, so that the knob 112 rotates normally. At this time, the baffle 103 drives the connecting disk 1 to rotate through the chassis 101 and the connecting column 8, so that the first connecting member 2 and the second connecting member 5 slide clockwise in the curved groove 9, thereby realizing the expansion of the first fixing block 3 and the second fixing block 5, thereby releasing the lock.

[0032] This locking structure 10 does not require a threaded connection of a screw thread, avoiding the use of only screw nuts for connection between the base station and the mounting pole, thereby greatly reducing the impact of wind pressure and wind shear force from the wind on the connection between the base station antenna and the mounting pole, preventing the base station antenna from falling off, reducing damage to the base station antenna, improving communication effects, and reducing the probability of safety accidents.

[0033] Specific working principle:

[0034] When it is necessary to lock the connection between the base station antenna and the mounting rod, rotate the knob 112 counterclockwise, and the knob 112 drives the No. 1 limit column 113 and the No. 2 limit column 114 to move in the baffle 103. When the No. 1 limit column 113 contacts the baffle 103, it drives the baffle 103 to move, and the baffle 103 drives the first special-shaped slider 104 inside it to move. The first special-shaped slider drives the first pawl to move on the first ratchet under the action of the spring 106. At the same time, the No. 2 limit column 114 first contacts the inclined block 116 of the second special-shaped slider 105. Under the action of the inclined surface and the spring 106, the No. 2 limit block contracts the second pawl 108, so that the knob 112 rotates normally. At this time The baffle 103 will drive the chassis 101 to rotate, the chassis 101 will drive the connecting column 8 to rotate, the connecting column 8 will drive the connecting disk 1 to rotate, so that the first connecting member 2 and the second connecting member 5 will slide counterclockwise in the curved groove 9, so as to realize the contraction of the first fixing block 3 and the second fixing block 5. When the base station antenna is contracted to be firmly connected to the mounting pole, the counterclockwise rotation of the knob 112 is stopped, because the cooperation of the first pawl 107, the first ratchet 109, the second pawl 108 and the second ratchet makes it impossible for the connecting disk 1 itself to rotate clockwise or counterclockwise, thereby achieving a self-locking effect, and then the first connecting member 2 and the second connecting member 5 can be connected by screws through the screw holes 11 to play a safety role.

[0035] When it is necessary to unlock the connection between the base station antenna and the mounting pole, first release the threaded connection between the first connecting member 2 and the second connecting member 5 through the screw hole 11, and then rotate the knob 112 clockwise. The knob 112 drives the second pawl 108 to move on the second ratchet 110. At the same time, the second limiting column 114 first contacts the inclined block 116 of the second special-shaped slider 105. Under the action of the inclined surface and the spring 106, the No. 1 limiting block contracts the first pawl 107, allowing the knob 112 to rotate normally. At this time, the baffle 103 drives the connecting disk 1 to rotate through the chassis 101 and the connecting column 8, so that the first connecting member 2 and the second connecting member 5 slide clockwise in the curved groove 9, realizing the expansion of the first fixing block 3 and the second fixing block 5, thereby releasing the lock.

[0036] This locking structure 10 does not require a threaded connection of a screw thread, avoiding the use of only screw nuts for connection between the base station and the mounting pole, thereby greatly reducing the impact of wind pressure and wind shear force from the wind on the connection between the base station antenna and the mounting pole, preventing the base station antenna from falling off, reducing damage to the base station antenna, improving communication effects, and reducing the probability of safety accidents.
