Description

Technical Field

[0001] This invention relates to the field of support devices for base station antennas, specifically a support device for base station antennas. Background Technology

[0002] A base station antenna is a communication device used to convert radio frequency electrical energy transmitted by a transmitter into electromagnetic wave energy, and then convert electromagnetic wave energy back into radio frequency electrical energy and transmit it to a receiver.

[0003] Patent publication number CN219203474U discloses a UWB base station antenna support structure, including a base plate and a mounting plate. By setting up support components, the UWB base station antenna can be stably supported, and the tilt angle of the UWB base station antenna can also be adjusted without disassembling and reinstalling the UWB base station antenna, saving time and effort. At the same time, the inclusion of shock-absorbing components prevents the UWB base station antenna from being damaged by collisions with the external environment, greatly increasing the practicality of the UWB base station antenna support structure.

[0004] Existing base station antenna support devices use multiple sets of bolts to install the antenna onto the support base. However, when installing the antenna one bolt at a time, the worker needs to manually hold the antenna body when screwing in the first bolt to prevent displacement of the antenna body due to stress during installation. This can cause the mounting holes on the antenna body to misalign with the mounting positions, making the installation of the antenna body inconvenient. Therefore, a support device for base station antennas is proposed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a support device for base station antennas, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support device for a base station antenna, comprising a base plate, a support seat fixed to the top of the base plate, a hinge seat fixed to the top of the support seat, a placement plate rotatably mounted on the inner side of the hinge seat, a return torsion spring fixed to the side wall of the placement plate, the side of the return torsion spring away from the placement plate fixed to the inner side of the hinge seat, a placement seat fixed to the top of the placement plate, an antenna mount fixed to the top of the placement seat by bolts, an antenna body fixed to the antenna mount, and a threaded rod rotatably mounted on the inner side of the support seat. The outer wall of the threaded rod is threaded with a threaded sleeve, which is slidably installed on the top inner side of the support base. The bottom of the placement plate is attached to a hinge block. By rotating the threaded rod, the threaded rod can drive the threaded sleeve to move. The threaded sleeve presses the hinge rod, causing the hinge rod to rotate at the hinge point, thereby enabling the hinge rod to press the hinge block to move. A hinge rod is hinged on the hinge block, and the end of the hinge rod away from the hinge block is hinged to the top of the threaded sleeve. The top of the placement base is provided with an alignment device for facilitating the installation of the antenna body and a stable clamping device for the antenna body. The alignment device includes an L-shaped block, a connecting spring, a positioning plate, a reset spring, a positioning post, and a positioning hole. The L-shaped block is slidably mounted on the top of the placement seat. One side of the connecting spring is fixed to the inner side of the top of the placement seat, and the other side of the connecting spring is fixed to the outer wall of the L-shaped block. The positioning plate is fixed to the end of the L-shaped block.

[0007] According to the above technical solution, the positioning post is slidably installed on the inner side of the positioning plate, one side of the return spring is fixed to the inner side of the positioning plate, the other side of the return spring is fixed to the end of the positioning post, and the positioning hole is opened on the outer wall of the antenna base.

[0008] According to the above technical solution, the clamping device includes a guide post, a return spring, a transmission frame, an L-shaped transmission block, a pressure block, a semi-circular block, an inclined block, a rubber pad, a clamping torsion spring, an auxiliary spring, a cylindrical block, a locking block, and a locking groove. The guide post is slidably installed on the top inner side of the placement seat. The bottom of the return spring is fixed to the inner side of the placement seat, and the top of the return spring is fixed to the bottom of the guide post. The transmission frame is fixed to the top of the guide rod. When the antenna mount shakes, it can squeeze the positioning plate, thereby driving the positioning plate to move. The positioning plate squeezes the inclined surface of the L-shaped transmission block, thereby driving the transmission frame and the guide post to move downward, causing the locking block to move out of the locking groove.

[0009] According to the above technical solution, the cylindrical block is fixed on the top of the placement seat, the pressure block is rotatably installed on the inner side of the cylindrical block, one side of the clamping torsion spring is fixed to the side wall of the pressure block, the other side of the clamping torsion spring is fixed to the inner top of the cylindrical block, the semi-circular block is fixed to the side wall of the pressure block, the slot is opened at the bottom of the pressure block, the locking block is fixed to the outer wall of the guide post, and the end of the locking block is in contact with the inner wall of the slot.

[0010] According to the above technical solution, the inclined block is slidably installed on the top inner side of the placement seat, one side of the auxiliary spring is fixed to the side wall of the inclined block, and the other side of the auxiliary spring is fixed to the top inner side of the placement seat.

[0011] According to the above technical solution, a protective device is also included. The protective device is installed on the placement plate and includes a moving block, a compression spring, a limiting block, a limiting groove, a fixing block, an air box, a piston plate, a connecting rod, a stop block, and a support spring. The moving block is slidably installed on the inner side of the placement plate, one side of the compression spring is fixed to the inner side of the placement plate, the other side of the compression spring is fixed to the outer wall of the moving block, and the limiting block is fixed to the outer wall of the moving block.

[0012] According to the above technical solution, the fixing block is fixed to the outer wall of the hinge block, and the limiting groove is formed on the side wall of the fixing block.

[0013] According to the above technical solution, the air box is fixed to the top of the base plate, the piston plate is slidably installed on the inner wall of the air box, the connecting rod is fixed to the top of the piston plate, the connecting rod passes through the top of the air box and the support seat, and is slidably connected at the passage, the stop block is fixed to the top of the connecting rod, the support spring is fixed to the bottom of the stop block, and the bottom of the support spring is fixed to the top of the support seat.

[0014] This invention provides a support device for a base station antenna. It has the following advantages: 1. This invention includes an alignment device. When the antenna needs to be installed, the antenna mount is placed in the four sets of positioning plates, which restricts the position of the antenna mount and prevents it from shifting due to bolts during installation on the mounting base, thus affecting installation efficiency. Furthermore, the positioning pins, positioning holes, and return spring restrict the direction of the antenna mount, aligning the threaded holes on the antenna mount with those on the mounting base, facilitating alignment and installation.

[0015] 2. This invention incorporates a clamping device. When the antenna mount is installed, and the antenna body encounters strong winds causing the antenna mount to sway, the antenna mount will impact the positioning plate, causing the positioning plate to move. This displacement of the positioning plate will compress the inclined surface of the L-shaped transmission block, causing the L-shaped transmission block to move downwards under pressure. This, in turn, will move the transmission frame downwards, causing the locking block to move out of the slot and releasing the limiting position on the pressure block. Through the cooperation of the clamping torsion spring, the pressure block can be pressed firmly against the top of the antenna mount, preventing the bolts from loosening and causing the antenna mount to sway up and down. Furthermore, when the pressure block rotates, the cooperation of the semi-circular block, the inclined block, and the rubber pad allows the semi-circular block to press against the inclined block, causing the rubber pad to press against the outer wall of the antenna mount, thus limiting and preventing the antenna mount from swaying back and forth.

[0016] 3. This invention, by incorporating a protective device, allows the inclined surface of the moving block to be pressed when the antenna body is adjusted to a tilted state and the transmission frame moves downward. This causes the moving block to move the limiting block out of the limiting groove, thereby releasing the limiting of the hinge block. The limiting seat no longer supports the placement plate. Furthermore, through the cooperation of the return spring, the placement plate can rotate and reset the antenna body, ensuring the antenna body is in a horizontal position. This prevents the antenna body from easily falling off when tilted and shaken by strong winds. When the return spring rotates the placement plate downward for reset, the cooperation of the air box, piston plate, connecting rod, stop block, and support spring provides cushioning during the rotational reset, preventing excessive impact and vibration from damaging the antenna body when it rotates downward rapidly.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 One embodiment of the present invention is as follows: a support device for a base station antenna, including a base plate 1, a support seat 2 fixed to the top of the base plate 1, a hinge seat 3 fixed to the top of the support seat 2, a placement plate 4 rotatably mounted on the inner side of the hinge seat 3, a return torsion spring 15 fixed to the side wall of the placement plate 4, the side of the return torsion spring 15 away from the placement plate 4 fixed to the inner side of the hinge seat 3, a placement seat 5 fixed to the top of the placement plate 4, an antenna seat 6 fixed to the top of the placement seat 5 by bolts, an antenna body 7 fixed to the antenna seat 6, a threaded rod 8 rotatably mounted on the inner side of the support seat 2, a threaded sleeve 9 threadedly connected to the outer wall of the threaded rod 8, the threaded sleeve 9 slidably mounted on the top inner side of the support seat 2, a hinge block 11 attached to the bottom of the placement plate 4, a hinge rod 10 hinged to the hinge block 11, the end of the hinge rod 10 away from the hinge block 11 hinged to the top of the threaded sleeve 9, and an alignment device for facilitating the installation of the antenna body 7 provided on the top of the placement seat 5; The alignment device includes an L-shaped block 121, a connecting spring 123, a positioning plate 122, a reset spring 124, a positioning post 125, and a positioning hole 126. The L-shaped block 121 is slidably mounted on the top of the placement seat 5. One side of the connecting spring 123 is fixed to the inner side of the top of the placement seat 5, and the other side of the connecting spring 123 is fixed to the outer wall of the L-shaped block 121. The positioning plate 122 is fixed to the end of the L-shaped block 121. The positioning post 125 is slidably mounted on the inner side of the positioning plate 122. One side of the reset spring 124 is fixed to the inner side of the positioning plate 122, and the other side of the reset spring 124 is fixed to the end of the positioning post 125. The positioning hole 126 is opened on the outer wall of the antenna base 6.

[0021] When the antenna needs to be installed, the antenna mount 6 is placed in the four sets of positioning plates 122 by setting the four sets of positioning plates 122, which can restrict the position of the antenna mount 6 and prevent the antenna mount 6 from shifting when it is installed on the mounting base 5 by bolts, thus affecting the installation efficiency. Furthermore, the positioning pin 125, positioning hole 126 and return spring 124 can restrict the direction of the antenna mount 6, thereby aligning the threaded hole on the antenna mount 6 with the threaded hole on the mounting base 5, thus facilitating the alignment and installation.

[0022] By rotating the threaded rod 8, the threaded sleeve 9 can move on the threaded rod 8, which can cause the threaded sleeve 9 to press against the hinge rod 10, so that the hinge rod 10 can drive the hinge block 11 and the placement plate 4 to rotate. In turn, the placement plate 4 can drive the antenna body 7 to rotate, causing the antenna body 7 to tilt and adjust the orientation of the antenna body 7, so as to receive better signals.

[0023] In this embodiment, when the antenna body 7 needs to be installed, the threaded rod 8 rotates clockwise, causing the threaded sleeve 9 to move to the right, thus moving the threaded sleeve 9 to the rightmost end. This allows the hinge rod 10 to drive the hinge block 11 to rotate, causing the hinge block 11 to press against the placement plate 4 and rotate it to a horizontal position. This places the antenna body 7 in the four positioning plates 122 at the top of the placement base 5, thereby limiting the position of the placement base 5 and preventing the antenna base 6 from shifting during installation. Furthermore, when the antenna base 6 is placed in the four sets of positioning plates 122, and... The spring force coefficient of the connecting spring 123 is five times that of the return spring 124. Therefore, when the antenna mount 6 is placed into the positioning plate 122, the antenna mount 6 first presses against the positioning post 125, causing the positioning post 125 to move into the positioning plate 122, thus compressing the return spring 124. When the antenna mount 6 is placed on the placement seat 5, by rotating the antenna mount 6, when the antenna mount 6 is rotated until the positioning hole 126 is aligned with the positioning post 125, the positioning post 125 can be inserted into the positioning hole 126 through the cooperation of the return spring 124, thus positioning the antenna mount 6.

[0024] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the placement base 5 is provided with a device for stabilizing the antenna body 7. The device includes a guide post 131, a return spring 132, a transmission frame 133, an L-shaped transmission block 134, a pressure block 135, a semi-circular block 137, an inclined block 139, a rubber pad 1311, a pressure torsion spring 136, an auxiliary spring 1310, a cylindrical block 1313, a locking block 1312, and a locking groove 138. The guide post 131 is slidably installed on the top inner side of the placement base 5, the bottom of the return spring 132 is fixed to the inner side of the placement base 5, the top of the return spring 132 is fixed to the bottom of the guide post 131, and the transmission frame 133 is fixed to the top of the guide post 131. The cylindrical block 1313 is fixed to the top of the placement seat 5. The pressure block 135 is rotatably installed on the inner side of the cylindrical block 1313. One side of the pressure torsion spring 136 is fixed to the side wall of the pressure block 135, and the other side of the pressure torsion spring 136 is fixed to the inner top of the cylindrical block 1313. The semi-circular block 137 is fixed to the side wall of the pressure block 135. The slot 138 is opened at the bottom of the pressure block 135. The slot 1312 is fixed to the outer wall of the guide post 131. The end of the slot 1312 is in contact with the inner wall of the slot 138. The inclined block 139 is slidably installed on the inner top of the placement seat 5. One side of the auxiliary spring 1310 is fixed to the side wall of the inclined block 139, and the other side of the auxiliary spring 1310 is fixed to the inner top of the placement seat 5.

[0025] Furthermore, when the antenna mount 6 is installed, if the antenna body 7 encounters strong winds, causing the antenna mount 6 to shake, the antenna mount 6 will impact the positioning plate 122, causing the positioning plate 122 to move. When the positioning plate 122 moves, it will press the inclined surface of the L-shaped transmission block 134, causing the L-shaped transmission block 134 to move downward under the pressure, thereby driving the transmission frame 133 to move downward, causing the locking block 1312 to move out of the locking slot 138, releasing the limit on the pressure block 135. With the cooperation of the clamping torsion spring 136, the pressure block 135 can press the top of the antenna mount 6 to prevent the bolts from loosening, causing the antenna mount 6 to drive the antenna body 7 to shake up and down. Furthermore, when the pressure block 135 rotates, the semicircular block 137, the inclined block 139, and the rubber pad 1311 work together to make the semicircular block 137 press the inclined block 139 to move, and make the rubber pad 1311 press against the outer wall of the antenna base 6 to limit the antenna base 6 and prevent the antenna base 6 from shaking back and forth, left and right, forward and backward.

[0026] It also includes a protective device, which is installed on the placement plate 4. The protective device includes a movable block 142, a compression spring 143, a limiting block 1410, a limiting groove 144, a fixing block 141, an air box 145, a piston plate 146, a connecting rod 147, a stop block 148, and a support spring 149. The movable block 142 is slidably installed on the inner side of the placement plate 4. One side of the compression spring 143 is fixed to the inner side of the placement plate 4, and the other side of the compression spring 143 is fixed to the outer wall of the movable block 142. The limiting block 1410 is fixed to the outer wall of the movable block 142. The wall, the fixing block 141 is fixed to the outer wall of the hinge block 11, the limiting groove 144 is opened in the side wall of the fixing block 141, the air box 145 is fixed to the top of the base plate 1, the piston plate 146 is slidably installed on the inner wall of the air box 145, the connecting rod 147 is fixed to the top of the piston plate 146, the connecting rod 147 passes through the top of the air box 145 and the support seat 2, and is slidably connected at the passage, the stop block 148 is fixed to the top of the connecting rod 147, the support spring 149 is fixed to the bottom of the stop block 148, and the bottom of the support spring 149 is fixed to the top of the support seat 2.

[0027] When the antenna body 7 is adjusted to a tilted state, and when the transmission frame 133 moves downward, it can press the inclined surface of the moving block 142, thereby causing the moving block 142 to drive the limiting block 1410 to move out of the limiting groove 144, thereby releasing the limiting of the hinge block 11. Thus, the limiting seat no longer supports the placement plate 4, and with the cooperation of the reset spring 124, the placement plate 4 can drive the antenna body 7 to rotate and reset, so that the antenna body 7 is in a horizontal state, preventing the antenna body 7 from being tilted and easily falling off when encountering strong winds. Furthermore, when the reset spring 124 drives the placement plate 4 to rotate downwards for reset, the cooperation of the air box 145, piston plate 146, connecting rod 147, stop block 148 and support spring 149 can buffer the placement plate 4 during the rotation reset, preventing excessive impact and vibration from the placement plate 4 driving the antenna body 7 to rotate downwards directly and quickly for reset, thus preventing damage to the antenna body 7.

[0028] In this embodiment, when the antenna mount 6 shakes and impacts the positioning plate 122, the positioning plate 122 moves, causing it to press against the inclined surface of the L-shaped transmission block 134. This pressing force causes the L-shaped transmission block 134 to move downwards. As the L-shaped transmission block 134 moves downwards, it drives the transmission frame 133 downwards. When the transmission frame 133 moves downwards, it causes the guide post 131 to move downwards, pressing against the return spring 132 and compressing it. Furthermore, when the guide post 131... As 31 moves downward, it can drive the locking block 1312 downward, causing the locking block 1312 to be removed from the locking slot 138, thereby releasing the limit on the pressure block 135. Because the clamping torsion spring 136 is in a compressed deformation state, it can drive the pressure block 135 to rotate, causing the pressure block 135 to press and position the top of the antenna mount 6. When the pressure block 135 rotates downward, it can cause the semicircular block 137 to press against the inclined surface of the inclined block 139. The elastic coefficient of the clamping torsion spring 136 is the same as that of the auxiliary spring 1310. Five times the number, thus enabling the semicircular block 137 to press against the inclined block 139 and move, causing the inclined block 139 to stretch the auxiliary spring 1310, and causing the inclined block 139 to drive the rubber pad 1311 to press against the outer wall of the antenna base 6, thus pressing and positioning the antenna base 6; and when the L-shaped transmission block 134 is not under pressure, the return spring 132 will drive the guide post 131 and the transmission frame 133 to move upward to reset, which can drive the locking block 1312 to reset upward, and by rotating the pressure block 135 upward, the clamping torsion spring 13 can be pressed. 6. When the pressure block 135 rotates to align with the slot 138 and the slot 1312, the slot 1312 abuts against the pressure block 135, and with the cooperation of the return spring 132, the slot 1312 can extend into the slot 138, thus positioning the pressure block 135. When the pressure block 135 rotates to reset, the semicircular block 137 does not press the inclined block 139. Because the auxiliary spring 1310 is in a stretched state, the auxiliary spring 1310 can drive the inclined block 139 to reset, thus not pressing the antenna mount 6. Furthermore, when the transmission frame 133 moves downward, it can press the top inclined surface of the moving block 142, causing the moving block 142 to move under the pressure, compressing the compression spring 143, and causing the moving block 142 to drive the limiting block 1410 to move out of the limiting groove 144, thereby releasing the limitation on the hinge block 11. Due to the influence of gravity, the hinge block 11 moves downward. Since the placement plate 4 is not supported, and the reset torsion spring 15 can drive the placement plate 4 to rotate downward, the placement plate 4 drives the antenna body 7 to be in a horizontal state. When the placement plate 4 rotates downward, it can press the placement plate 4 against the stop block 148. The elastic coefficient of the reset torsion spring 15 is five times that of the elastic coefficient of the support spring 149, so that the placement plate 4 can press the stop block 148 downward, driving the connecting rod 147 to move downward, so that the piston plate 146 can compress the gas in the gas box 145, compressing the gas, thereby slowing down the rotation speed of the placement plate 4 and providing buffering. When the hinge block 11 needs to be installed on the placement plate 4, first rotate the threaded rod 8 and adjust the threaded sleeve 9 to the rightmost end. By pushing the two sets of moving blocks 142 away from each other, the compression spring 143 is compressed and deformed. Then, manually pick up the hinge block 11 so that the top of the hinge block 11 fits against the bottom of the placement plate 4, thereby aligning the limiting block 1410 with the limiting groove 144. By releasing the moving block 142, the compression spring 143 can help the moving block 142 drive the limiting block 1410 into the limiting groove 144, thus fixing the fixing block 141 and the hinge seat 3.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
