Description

Technical Field

[0001] The present invention relates to the technical field of antenna fixing, and in particular to an antenna fixing structure for network information. Background Art

[0002] The base station antenna is a very important component of the mobile communication network. It is responsible for transmitting and receiving radio signals to achieve communication between mobile phones and other wireless devices. In order to overcome the signal shielding problem in areas with many obstacles and cover a specific geographical area or optimize the signal propagation direction, the base station antenna usually needs to be erected at a high place and set at a certain angle. After the antenna is set up, it is usually fixed to the pole using connecting parts such as a clamp, which makes a certain distance between the antenna and the pole. At the same time, this distance is usually fixed and cannot be adjusted independently. In windy weather, this distance will become part of the lever arm. Even if the wind force remains unchanged, the torque of the wind will increase due to the increase in the length of the lever arm, causing the antenna to be subjected to greater pressure, thereby affecting its stability and safety, and even causing damage to the connection between the antenna and the pole, affecting the normal use of the antenna.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0029] Embodiment 1: Considering that the distance between the existing antenna and the pole cannot be adjusted autonomously after being fixed, the antenna will be subjected to greater pressure in windy weather, which will affect its stability and safety, and even cause damage to the connection between the antenna and the pole, affecting the normal use of the antenna. The present invention proposes the following antenna fixing structure for network information.

[0030] like Figure 1-Figure 4As shown, it includes a support rod 1, and a holding rod 2 is installed on the support rod 1. The number of the holding rod 2 and other parts connected thereto can be selected according to actual needs. The text and the figure are described by taking a holding rod 2 and a part connected to the holding rod 2 as an example. The upper part of the holding rod 2 is slidably connected with a transmission rack 3, and the lower end of the holding rod 2 is slidably connected with a positioning rod 4. A limiting mechanism is arranged at the right end of the positioning rod 4. The positioning rod 4 is provided with a network antenna 5 through the limiting mechanism thereon. The upper part of the left side of the network antenna 5 is slidably connected with the transmission rack 3, and the transmission rack 3 drives the network antenna 5 to move synchronously during the movement. The upper part of the holding rod 2 A connecting piece is fixedly connected, and the holding rod 2 is rotatably connected to a connecting shaft 6 through the connecting piece thereon. The connecting shaft 6 is fixedly connected to a transmission gear 7 meshing with the transmission rack 3. During the rotation process, the connecting shaft 6 drives the transmission rack 3 to move synchronously through the meshing of the transmission gear 7 with the transmission rack 3. The connecting shaft 6 is fixedly connected to a worm wheel 8. The holding rod 2 is rotatably connected to a worm 9 driven by the worm wheel 8. The worm 9 drives the connecting shaft 6 and other parts thereon to rotate synchronously through the transmission of the worm wheel 8, and at the same time, the network antenna 5 is locked so that the network antenna 5 cannot drive the transmission gear 7 to move under the action of wind. The upper end of the holding rod 2 is provided with a driving mechanism for driving the worm 9 to rotate.

[0031] like Figure 1-Figure 4As shown, the driving mechanism includes a connecting sleeve 11, which is rotatably connected to one end of the holding rod 2, and a movable shell 12 is fixedly connected to the upper end of the connecting sleeve 11. The movable shell 12 is used to drive the connecting sleeve 11 to rotate when blown by the wind. The movable shell 12 is fixedly connected to a liquid storage shell 13, and a piston rod 14 is slidably connected to the inside of the liquid storage shell 13. The inside of the liquid storage shell 13 is filled with hydraulic oil. A spring is fixedly connected between the piston rod 14 and the liquid storage shell 13 to maintain the initial position of the adjacent piston rod 14 and drive the piston rod 14 to return to the initial position after moving, and the piston There is friction between the rod 14 and the liquid storage shell 13, and the friction between the piston rod 14 and the liquid storage shell 13 is less than the elastic force of the spring between the two. The piston rod 14 is fixedly connected with an extrusion plate 15, and the extrusion plate 15 slides in the moving shell 12. The moving shell 12 and the extrusion plate 15 are both provided with through holes distributed in a matrix. The extrusion plate 15 is blown by the wind and moves along the inside of the moving shell 12 and drives the piston rod 14 to move synchronously to the left, squeezing out the hydraulic oil in the liquid storage shell 13. The lower side of the connecting sleeve 11 is fixedly connected with a liquid storage ring 16, and the liquid storage ring 16 is filled with hydraulic oil. The connecting sleeve 11 drives the liquid storage ring 16 to rotate synchronously. The liquid storage ring 16 is connected to the liquid storage shell 13 through a connecting pipe. The hydraulic oil squeezed out of the liquid storage shell 13 flows into the liquid storage ring 16 through the connecting pipe. The lower side of the liquid storage ring 16 is rotatably connected to a connecting ring 17. The connecting ring 17 is fixedly connected and connected to a liquid storage pipe 18. The hydraulic oil in the liquid storage ring 16 moves downward along the liquid storage pipe 18. The liquid storage pipe 18 is fixedly connected to the holding rod 2 through a connecting rod. The inside of the liquid storage pipe 18 is slidably connected to a push plate 19. The push plate 19 moves due to the change in the volume of the hydraulic oil in the liquid storage pipe 18. A transmission module is provided between 19 and the worm 9, and the transmission module is used to drive the worm 9 to rotate. The transmission module is shown in the figure by taking a mutually meshing gear and rack as an example, and the rack is fixedly connected to the lower side of the push plate 19, and the gear is fixedly connected to the worm 9. The left side of the movable shell 12 is an arc surface, and the diameter of the circle where the arc surface is located is the same as the outer diameter of the liquid storage ring 16, but the center of the circle where the arc surface of the movable shell 12 is located is not on the same vertical line as the center of the liquid storage ring 16, so as to avoid that when the wind comes from the left side of the movable shell 12, the movable shell 12 cannot be blown by the wind and rotate synchronously.

[0032] like Figure 1 and Figure 5-Figure 7As shown, the limiting mechanism includes a fixed shell 21, the interior of the fixed shell 21 is filled with hydraulic oil, the fixed shell 21 is fixedly connected to the right side of the positioning rod 4, the interior of the fixed shell 21 is slidably connected with a moving rod 22, a spring is fixedly connected between the moving rod 22 and the fixed shell 21, for maintaining the initial position of the moving rod 22, and driving the moving rod 22 to return to the initial position after movement, the positioning rod 4 is provided with a first infusion hole 23, the first infusion hole 23 is communicated with the fixed shell 21, the left part of the positioning rod 4 is provided with a slide groove, the slide groove of the positioning rod 4 is communicated with the first infusion hole 23, the hydraulic oil in the fixed shell 21 is transported to the slide groove of the positioning rod 4 through the first infusion hole 23, the slide groove of the positioning rod 4 is slidably connected with a limiting block 24, and the limiting block 24 is affected by the volume of the hydraulic oil in the slide groove of the positioning rod 4 The limit block 24 is limited and matched with the holding pole 2 to limit the positioning rod 4, so that the positioning rod 4 cannot move to the left. The right end of the positioning rod 4 is fixedly connected with a fixed shaft 25, and the fixed shaft 25 is rotatably connected with a U-shaped block 26. The U-shaped block 26 is fixedly connected to the network antenna 5. In the process of driving the network antenna 5 to move to the left, the transmission rack 3 first drives the U-shaped block 26 to rotate around the fixed shaft 25 to a vertical position, and then moves to the left. The limit block 24 is provided with an inclined surface, and the inclined surface on the limit block 24 is pressed and matched with the holding pole 2. In the process of the limit block 24 moving to the right, the inclined surface of the limit block 24 is squeezed by the holding pole 2 and moves downward, and the U-shaped block 26 is pressed and matched with the moving rod 22, and the position of the moving rod 22 is controlled by the position of the U-shaped block 26.

[0033] like Figure 5-Figure 8As shown, the U-shaped block 26 is fixedly connected to the rotating shell 31, the fixed shaft 25 passes through the rotating shell 31 and is rotatably connected thereto, a moving plate 32 is fixedly connected inside the rotating shell 31, the U-shaped block 26 drives the moving plate 32 to rotate synchronously through the transmission of the rotating shell 31, the moving plate 32 is slidably connected to the fixed shaft 25, the fixed shaft 25 is fixedly connected to a fixed plate 33 that slides inside the rotating shell 31, hydraulic oil is filled between the opposite sides of the fixed plate 33 and the moving plate 32, and the moving plate 32 changes the hydraulic pressure between it and the fixed plate 33 during the movement. The volume of the oil, the positioning rod 4 is provided with a second infusion hole 34, the second infusion hole 34 is connected with the rotating shell 31 through a connecting pipe, the communication position of the second infusion hole 34 and the adjacent connecting pipe is located between the fixed plate 33 and the movable plate 32, the second infusion hole 34 is slidably connected with an extrusion rod 35, when the volume of the hydraulic oil in the right part of the second infusion hole 34 increases, the extrusion rod 35 is moved to the left by the extrusion force, the left part of the positioning rod 4 is provided with a limiting groove, the limiting groove of the positioning rod 4 is connected with the second infusion hole 34, when the extrusion rod 35 moves to the left During the left movement, the hydraulic oil on the right side of the second infusion hole 34 is squeezed into the limit groove of the positioning rod 4. The limit groove of the positioning rod 4 is slidably connected with a connecting plate 36. When the hydraulic oil in the limit groove of the positioning rod 4 increases, the connecting plate 36 is squeezed downward. The diameter of the right side of the squeezing rod 35 is smaller than the diameter of the left side. The cross-sectional area of ​​the right side of the second infusion hole 34 is smaller than the cross-sectional area of ​​the left side, which is used to increase the moving distance of the connecting plate 36. The side of the connecting plate 36 away from the limit block 24 is fixedly connected with a plurality of linear arrays. An elastic telescopic rod 37 is slidably connected to the positioning rod 4. A limiting groove is provided on the lower side of the holding rod 2. The telescopic end of the elastic telescopic rod 37 slides in the limiting groove of the holding rod 2. The elastic telescopic rod 37 is provided with an inclined surface with the same inclination direction as the inclined surface on the limiting block 24. The limiting groove of the holding rod 2 is provided with an inclined surface that is extruded and matched with the inclined surface on the telescopic end of the elastic telescopic rod 37, so that when the elastic telescopic rod 37 moves to the left, the telescopic end of the elastic telescopic rod 37 is subjected to the extrusion force and moves upward.

[0034] The present invention adopts a new connection method to replace the existing fixing method of the network antenna 5, that is, to replace the current fixing method of the clamp, and realizes the function of protecting the network antenna 5 in windy weather. The specific implementation method is as follows:

[0035] (The following description is based on the example of wind coming from the right side) After the wind starts to blow from the outside, the wind blows the movable shell 12, and blows the right side of the movable shell 12 to the windward side, and then the wind blows the extrusion plate 15 (when the wind force is small, that is, when the wind force is smaller than the elastic force of the spring in the liquid storage shell 13, it will not affect the normal use of the network antenna 5, and no adjustment is required to the network antenna 5 at this time), and the wind blown onto the extrusion plate 15 flows to the left along the through hole on the extrusion plate 15 into the movable shell 12, and flows out along the through hole on the left side of the movable shell 12.

[0036] When the external wind force increases to be greater than the elastic force of the spring in the liquid storage shell 13, it proves that the external wind force has increased to a certain extent, that is, the external wind force will affect the network antenna 5. At this time, if the network antenna 5 continues to be used, the network antenna 5 is at risk of being damaged. Therefore, when the wind blows onto the extrusion plate 15, the extrusion plate 15 is slowly moved toward the inside of the movable shell 12 by the wind force, that is, the extrusion plate 15 is slowly moved to the left by the wind force. At the same time, the extrusion plate 15 drives the piston rod 14 and moves synchronously to the left along the liquid storage shell 13. The piston rod 14 squeezes the hydraulic oil in the liquid storage shell 13 into the connecting ring 17 through the liquid storage tube 18, and flows into the liquid storage tube 18 along the connecting ring 17, so that the push plate 19 drives the transmission module thereon to move synchronously, thereby driving the worm 9 to rotate.

[0037] While the worm 9 rotates, the transmission gear 7 is driven to rotate synchronously by the worm 9 through the transmission of the worm wheel 8 and the connecting shaft 6, and the transmission gear 7 drives the transmission rack 3 to move synchronously to the left by meshing with the transmission rack 3. At the same time, the transmission rack 3 drives the upper part of the network antenna 5 to move synchronously to the left, so that the network antenna 5 rotates around the center of the fixed axis 25. At the same time, the network antenna 5 slides relatively with the transmission rack 3, that is, the contact position between the network antenna 5 and the transmission rack 3 gradually moves downward, and then the network antenna 5 is converted from an inclined state to a vertical state, reducing the distance between the upper part of the network antenna 5 and the holding pole 2, so that the center of gravity of the network antenna 5 is closer to the holding pole 2, that is, reducing the torque between the upper part of the network antenna 5 and the holding pole 2, reducing the shaking amplitude of the network antenna 5 due to wind force, and making the network antenna 5 more stable.

[0038] During the rotation of the network antenna 5 around the center of the fixed axis 25, the lower part of the network antenna 5 drives the U-shaped block 26 to rotate synchronously, and at the same time, the U-shaped block 26 squeezes the lower end of the moving rod 22, so that the moving rod 22 is squeezed and gradually moves upward along the fixed shell 21, and the spring in the fixed shell 21 is compressed and stored. At the same time, during the upward movement of the moving rod 22, the hydraulic oil in the sliding groove of the positioning rod 4 flows along the first infusion hole 23 into the fixed shell 21 (the principle of negative pressure extraction), and then the limit block 24 gradually moves downward, until the network antenna 5 is converted from the inclined state to the vertical state, the moving rod 22 moves upward to the limit position, and at the same time, the limit block 24 moves downward to the limit position, that is, the limit block 24 moves downward to the position where it loses contact with the holding pole 2.

[0039] In the process of the network antenna 5 driving the U-shaped block 26 to rotate synchronously, the U-shaped block 26 drives the rotating shell 31, and the rotating shell 31 drives the movable plate 32 to rotate synchronously, and then the movable plate 32 transports the hydraulic oil between it and the fixed plate 33 to the second infusion hole 34 through the adjacent connecting pipe during the rotation, so that the extrusion rod 35 moves to the left due to the extrusion force, and the extrusion rod 35 squeezes the hydraulic oil in the second infusion hole 34 into the limiting groove of the positioning rod 4, so that the connecting plate 36 is subjected to the extrusion force and drives the several elastic telescopic rods 37 thereon to move downward synchronously, until the network antenna 5 rotates to a vertical state, and the elastic telescopic rod 37 moves downward synchronously to the limit position, at which time the telescopic end of the elastic telescopic rod 37 is located in the limiting groove of the holding pole 2.

[0040] After the network antenna 5 is rotated to a vertical state, as the transmission rack 3 continues to move to the left, the transmission rack 3 drives the network antenna 5 and other parts connected thereto to move synchronously to the left, thereby reducing the distance between the network antenna 5 and the pole 2, and further reducing the torque between the network antenna 5 and the pole 2.

[0041] In the process of the network antenna 5 moving to the left, the network antenna 5 drives a plurality of elastic telescopic rods 37 to move to the left synchronously through the transmission of the positioning rod 4. The following description takes the movement process of the leftmost elastic telescopic rod 37 as an example:

[0042] When the elastic telescopic rod 37 moves to the left along the limiting groove of the holding pole 2 until it contacts the inclined surface on it, as the elastic telescopic rod 37 continues to move to the left, the inclined surface on the limiting groove of the holding pole 2 squeezes the inclined surface of the telescopic end of the elastic telescopic rod 37, causing the telescopic end of the elastic telescopic rod 37 to move upward, and compresses the elastic member in the fixing portion of the elastic telescopic rod 37 to store force until the telescopic end of the elastic telescopic rod 37 moves to the left until it loses contact with the inclined surface on the limiting groove of the holding pole 2, at which time the telescopic end of the elastic telescopic rod 37 resets downward, and the telescopic end of the elastic telescopic rod 37 limits the positioning rod 4, preventing the positioning rod 4 from moving to the right, i.e., limiting the network antenna 5, further increasing the stability of the network antenna 5 and reducing the probability of damage to the network antenna 5. The specific movement process of the remaining elastic telescopic rods 37 will not be described in detail, and all of them can refer to the above.

[0043] Until the network antenna 5 moves to the left to the extreme position, the transmission rack 3 and the positioning rod 4 and other parts connected to the two move to the left to the extreme position synchronously. At this time, the telescopic end of the rightmost elastic telescopic rod 37 moves to the left to the left side of the holding pole 2, that is, the telescopic end of the rightmost elastic telescopic rod 37 is limited by the holding pole 2. At this time, the network antenna 5 moves to the left to the position in contact with the holding pole 2, and the wind force received by the network antenna 5 is directly transmitted to the holding pole 2, thereby further increasing the stability of the network antenna 5 and reducing the shaking amplitude of the network antenna 5 affected by the wind, that is, reducing the probability of damage to the network antenna 5.

[0044] Until the wind force in the external environment is reduced to less than the elastic force of the spring in the liquid storage shell 13, under the action of the spring in the liquid storage shell 13, the piston rod 14 drives the extrusion plate 15 to slowly return to the initial position, and then the hydraulic oil in the connecting ring 17 is drawn back into the liquid storage shell 13, and the push plate 19 drives the worm 9 to rotate in the opposite direction through the transmission module thereon, thereby driving the transmission rack 3 to move rightward, so that the network antenna 5 is reset to the initial position, that is, the network antenna 5 is converted from a vertical state to an inclined state, until the network antenna 5 is reset to the initial position, and at the same time, the other parts connected to the positioning rod 4 are synchronously reset to the initial position (the specific process is opposite to the process of converting the network antenna 5 from an inclined state to a vertical state, and will not be described in detail), and in the process of the transmission rack 3 continuing to move to the right, the transmission rack 3 drives the network antenna 5 and other parts connected thereto to move rightward synchronously.

[0045] In the process of resetting the network antenna 5 from the vertical state to the inclined state, the network antenna 5 drives the rotating shell 31 and the movable plate 32 to move synchronously, and then draws the hydraulic oil in the upper limit groove of the positioning rod 4 back to the right part of the second infusion hole 34, so that the connecting plate 36 drives the multiple elastic telescopic rods 37 of the linear array thereon to move upward synchronously. When the network antenna 5 is reset to the initial position, the connecting plate 36 moves upward to the initial position synchronously. At this time, the multiple elastic telescopic rods 37 of the linear array are completely retracted into the limiting groove of the positioning rod 4, that is, the telescopic end of the elastic telescopic rod 37 does not contact the holding rod 2, and the limiting of the telescopic end of the elastic telescopic rod 37 on the holding rod 2 is released.

[0046] Until the limit block 24 moves to the right and contacts the left side of the holding pole 2, the holding pole 2 squeezes the inclined surface on the limit block 24, causing the limit block 24 to move downward, and transports the hydraulic oil in the slide groove of the positioning rod 4 to the fixed shell 21, causing the moving rod 22 to move upward again, until the limit block 24 moves to the right to a position where its right side contacts the right side of the holding pole 2, the moving rod 22 moves downward again under the action of the adjacent spring, and the limit block 24 moves upward again, the holding pole 2 is limited by the limit block 24, and at this time the network antenna 5 is reset to the initial position to the right.

[0047] Embodiment 2: Considering that the existing antenna fixing device lacks a fall-proof design for the antenna body, if the antenna body accidentally falls off from the supporting device in a densely populated urban area, it will cause life danger to the public and cause unnecessary economic losses. Based on Embodiment 1, the present invention further proposes the following measures:

[0048] like Figure 1 and Figure 9-11As shown, it also includes a positioning block 41, which is embedded in the middle of the front side of the holding pole 2. The positioning block 41 is fixedly connected to the limiting wheel 42 through a connecting rod. The front side of the limiting wheel 42 is provided with an internal gear. The limiting wheel 42 and the positioning block 41 rotate together and are connected to a winding roller 43. A torsion spring is fixedly connected between the front side of the winding roller 43 and the limiting wheel 42. In the initial position, the torsion spring on the winding roller 43 is in a power storage state. The winding roller 43 is wound with a connecting belt fixedly connected to the network antenna 5. The torsion spring on the winding roller 43 is used to maintain the initial position of the winding roller 43 and drive the winding roller 43 to reset to the initial position after moving. At the same time, it is used to rewind the connecting belt released by the winding roller 43 on it, and maintain the connecting belt between the winding roller 43 and the network antenna 5 in a straight state. The front end of the winding roller 43 is fixedly connected to a U-shaped piece 44, and the winding roller 43 is pulled by the connecting belt thereon to drive the U The limiting member 45 is provided with a limit member 45 on the front side of the limit wheel 42, and a through hole is provided in the middle of the limit member 45, and the through hole of the limit member 45 is provided with two symmetrically distributed arc-shaped portions, both of which are not concentric with the center of the circle of the limit member 45, and are both eccentric arc-shaped portions. The limit member 45 is limitedly matched with the internal gear on the limit wheel 42, and there is friction between the limit member 45 and the limit wheel 42, and the limit member 45 is squeezed and matched with the U-shaped member 44. In the process of slow rotation of the winding roller 43, the winding roller 43 drives the limit member 45 to rotate synchronously through the U-shaped member 44. In the process of rapid rotation of the winding roller 43, the right part of the U-shaped member 44 pushes the arc-shaped portion on the lower side of the limit member 45, so that the limit member 45 moves downward under the extrusion force, and then the limit member 45 contacts with the internal gear on the limit wheel 42, limits the limit member 45, and then limits the winding roller 43.

[0049] like Figure 1 and Fig.12 As shown, a connecting seat 51 is fixedly connected to the lower side of the network antenna 5, and a protective shell 52 is limitedly slidably connected to the connecting seat 51. The protective shell 52 slides with the network antenna 5, and the protective shell 52 is used to protect the network antenna 5 from being affected by wind and sand in the external environment. A guide rod 53 is fixedly connected to the lower side of the protective shell 52. The protective shell 52 drives the guide rod 53 to move synchronously during the movement. The guide rod 53 is provided with a through groove. The support rod 1 is fixedly connected to a guide block 54 through a connecting piece. The guide block 54 is provided with a guide groove. The guide groove on the guide block 54 is arc-shaped, and the center of the circle where the arc is located is located on the center line of the fixed shaft 25. A moving column 55 is slidably connected in the guide groove of the guide block 54, and the moving column 55 slides in the through groove of the guide rod 53. The guide rod 53 is guided by the moving column 55, so that the guide rod 53 moves upward while moving to the left.

[0050] In the process of the network antenna 5 being transformed from the inclined state to the vertical state (with Fig.12The network antenna 5 drives the protective shell 52 and the two guide rods 53 thereon to rotate synchronously through the transmission of the connecting seat 51, thereby lowering the height of the upper end of the guide rod 53. The guide rod 53 continuously changes its contact position with the moving column 55 during the rotation process, so that the moving column 55 gradually moves downward along the guide groove of the guide block 54. Until the network antenna 5 moves to a vertical state, the moving column 55 synchronously moves downward to the extreme position. At this time, the moving column 55 contacts the uppermost end of the through groove of the guide rod 53, that is, the moving column 55 moves downward to the lowermost side of the guide groove of the guide block 54.

[0051] In the subsequent process of the network antenna 5 moving to the right, the network antenna 5 drives the protective shell 52 and the guide rod 53 to move to the right synchronously, and the moving column 55 cooperates with the through groove of the guide rod 53, so that the guide rod 53 drives the protective shell 52 to move upward synchronously in the process of moving to the right, and further changes the contact position of the moving column 55 and the guide rod 53, until the protective shell 52 moves upward to contact the network antenna 5. In the process of the protective shell 52 continuing to move upward, the network antenna 5 is gradually covered by the protective shell 52. When the network antenna 5 moves to the right to the extreme position, the protective shell 52 completely covers the network antenna 5 therein (but the protective shell 52 has not moved upward to the extreme position at this time), and the protective shell 52 protects the network antenna 5 to prevent the sand and gravel carried in the wind from colliding with the network antenna 5, causing the network antenna 5 to be deformed or even damaged by the collision, thereby affecting the normal use of the network antenna 5.

[0052] In the process of the network antenna 5 being converted from a vertical state to a tilted state, the network antenna 5 drives the protective shell 52 and the connecting seat 51 to rotate synchronously, and then drives the guide rod 53 to rotate synchronously, so that the right end of the guide rod 53 moves upward again, and at the same time, the contact position between the guide rod 53 and the movable column 55 changes again, so that the movable column 55 moves upward along the guide groove of the guide block 54, until the network antenna 5 is reset to the tilted state, and the guide rod 53 and the movable column 55 both move upward to the extreme position.

[0053] When the network antenna 5 drives the connecting seat 51, the protective shell 52 and the guide rod 53 to reset to the right, the guide rod 53 simultaneously drives the protective shell 52 to move downward. When the network antenna 5 resets to the right to the initial position, the guide rod 53 and the protective shell 52 simultaneously move downward to the initial position.

[0054] During the process of the above-mentioned network antenna 5 moving to the left, the network antenna 5 drives the connecting belt connected thereto to move synchronously, loosens the connecting belt between the network antenna 5 and the winding roller 43, and then the winding roller 43 winds the connecting belt between the network antenna 5 and the winding roller 43 around it under the action of the adjacent torsion spring, and the winding roller 43 drives the limiting member 45 to rotate synchronously through the transmission of the U-shaped member 44. During the process of the above-mentioned network antenna 5 resetting to the initial position, the network antenna 5 pulls out the connecting belt wound on the winding roller 43 again, and drives the winding roller 43 and other parts connected thereto to rotate synchronously, and twists the torsion spring between the winding roller 43 and the limiting wheel 42 to accumulate force until the network antenna 5 moves to the right to the initial position, and the winding roller 43 no longer rotates. At this time, the connecting belt between the network antenna 5 and the winding roller 43 is in a taut state.

[0055] During the normal use of the device, if the network antenna 5 falls down due to an emergency (i.e., the transmission rack 3 and the positioning rod 4 are affected by the outside world and lose connection with the network antenna 5), ​​the instantaneous speed of the network antenna 5 falling down is relatively large, that is, the instantaneous pulling force generated by the network antenna 5 on the winding roller 43 is relatively large, causing the speed of the winding roller 43 to increase, thereby increasing the rotation speed of the U-shaped member 44. When the rotation speed of the U-shaped member 44 increases, the limiting member 45, under the action of the friction force between the limiting member 45 and the limiting wheel 42, makes the rotation speed of the limiting member 45 lower than the rotation speed of the U-shaped member 44, thereby causing the limiting member 45 and the U-shaped member 44 to move relative to each other. Even if the right end of the U-shaped member 44 moves along the limiting wheel 42, the limiting member 45 and the U-shaped member 44 will move relative to each other. The arc-shaped portion on the lower side of the member 45 moves, so that the limiting member 45 moves downward relative to the U-shaped member 44 under the extrusion force, until the limiting tooth at the lower end of the limiting member 45 contacts the internal gear of the limiting wheel 42, and the limiting member 45 is limited by the internal gear of the limiting wheel 42, and then the U-shaped member 44 is limited, that is, the winding roller 43 is limited, so that the winding roller 43 cannot continue to rotate, that is, the connecting belt on the winding roller 43 is locked to prevent the network antenna 5 from continuing to move downward, that is, the network antenna 5 is locked to prevent the network antenna 5 from falling to the ground in an emergency, causing damage to the network antenna 5, reducing economic losses, and at the same time avoiding threats to the safety of the staff or other formations on the ground.

[0056] After the above-mentioned emergency occurs, the staff quickly repairs the damaged network antenna 5. After the repair is completed, the network antenna 5 is reinstalled on the pole 2 and adjusted to a suitable position to ensure that the network antenna 5 can continue to transmit signals.

[0057] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art may make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments.
