[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example

[0035] A signal communication line connection structure, such as Figure 1-4 As shown, it includes a lower support rod 2, an upper support rod 3 and a support base 4 fixedly connected between the upper support rod 3 and the lower support rod 2. A winding chamber 41 is opened in the support base 4, and the cable 12 of the communication line can be accommodated and wound through the winding chamber 41, thereby providing a certain degree of protection for the cable 12.

[0036] The antenna device 1 can be placed on the upper support rod 3, and two sets of upper and lower support frames 14 are fixed to the back of the antenna device 1. The support frames 14 are fixedly mounted on the upper support rod 3 through the mounting frame 15, thereby fixing and supporting the antenna device 1; the upper support frame 14 is longer than the lower support frame 14, so that the antenna device 1 is tilted downward and can release signals to the target on the bottom surface; one end of the mounting frame 15 is rotatably connected to the support frame 14, and the angle can be locked and fixed by bolts, so that the tilt angle of the antenna device 1 can be adjusted and controlled, and the other end of the mounting frame 15 is fixedly connected to the clamp, forming a fixed support structure between the clamp and the upper support rod 3.

[0037] The lower support rod 2 and the upper support rod 3 are installed in a coaxial vertical position, and the support base 4 is fixedly connected to the position between the upper support rod 3 and the lower support rod 2. A hollow winding cavity 41 is set in the support base 4, which can be used to accommodate the cable 12 supported by the winding antenna.

[0038] Cable 12 is connected to the lower end of antenna assembly 1 and extends downward to connect to the equipment on the bottom surface below. A cable inlet 13 is provided on the outer periphery of support base 4 for the cable 12 of antenna assembly 1 to pass through. Multiple guide wheels 131 are installed inside the inlet to guide the extension and retraction of cable 12 at cable inlet 13, maintaining its stability.

[0039] The winding chamber 41 is equipped with a rotating mechanism 10 and a connecting mechanism 11. The connecting mechanism 11 is driven to rotate by the rotating mechanism 10. The connecting mechanism 11 includes a connecting frame 113. A plurality of clamps 114 are fixedly connected to the outer periphery of the connecting frame 113. The clamps 114 can clamp and secure the cable 12. The connecting frame 113 can rotate under the drive of the rotating mechanism 10, thereby spirally winding the cable 12.

[0040] Both the upper support rod 3 and the lower support rod 2 are hollow, and are provided with a tube cavity 42 linked to the winding cavity 41. After the cable 12 is extended into the winding cavity 41, it is extended downward from the tube cavity 42 of the lower support tube, thereby extending to the ground position and connecting with other communication equipment. It can cover the cable 12 to avoid damage from the outside.

[0041] A transmission shaft 9 is rotatably connected within the tubular cavity 42 of the upper support rod 3. The transmission shaft 9 is rotationally supported by multiple bearing assemblies, thereby maintaining the rotational stability of the transmission shaft 9. The upper end of the transmission shaft 9 is rotationally driven by a three-cup wind measuring device 8. The three-cup side wind device has three semicircular cups distributed in a ring. When affected by external wind force, it can drive the rotation of the three-cup side wind device, thereby driving the rotation of the lower transmission shaft 9. The lower end of the transmission shaft 9 is connected to the rotating mechanism 10. The rotation of the lower end of the transmission shaft 9 can drive the rotating mechanism 10, thereby driving the connection mechanism 11 on the rotating mechanism 10 to rotate, and then driving the cable 12 in the winding chamber 41 to have a winding movement tendency.

[0042] Specifically, a transmission box 5 is installed at the upper end of the upper support rod 3, the inner cavity of the transmission box 5 is connected to the tubular cavity 42 of the upper support rod 3, the upper end of the transmission box 5 is rotatably connected to the rotating shaft 7, and a three-cup wind measuring device 8 is installed at the upper end of the rotating shaft 7; in order to maintain the stability of the rotating shaft 7, a rotating sleeve 51 can be fixedly connected to the upper end of the transmission box 5, thereby rotatably supporting the rotating shaft 7.

[0043] A transmission mechanism 6 is disposed within the transmission case 5. This mechanism links the rotating shaft 7 with the transmission shaft 9, transmitting the rotational motion output by the three-cup wind measuring device 8 downward. Specifically, the transmission mechanism 6 includes a transmission sleeve 61, the lower end of which extends into the tubular cavity 42 of the upper support rod 3 and is fixedly connected to the transmission shaft 9. A transmission disc 62 is fixedly connected to the outer periphery of the upper end of the transmission sleeve 61, and power is transmitted between the larger transmission disc 62 and the transmission sleeve. The lower end of the rotating shaft 7 extends into the transmission sleeve 61, and a rotating support member 66 is rotatably connected to the transmission sleeve 61, thereby further maintaining the stability of the rotating shaft 7.

[0044] The transmission connection between the transmission sleeve and the transmission disc can be achieved by gear transmission, or the transmission of rotational motion can also be achieved by friction. Specifically, a fixed gear 65 can be installed inside the rotating shaft 7 corresponding to the transmission box 5, and the fixed gear 65 can move synchronously with the rotating shaft 7; and a transmission ring gear 63 is provided on the outer periphery of the transmission disc 62. A driven gear 64 is installed between the transmission ring gear 63 and the inner periphery of the fixed gear 65. The driven gear 64 can mesh with the transmission ring gear 63 and the fixed gear 65 for transmission. Therefore, through the rotation of the rotating shaft 7, it can be decelerated by the gear structure and then output a more stable rotational motion to the transmission shaft 9, driving the movement of the rotating mechanism 10 in the winding box.

[0045] In the winding chamber 41, the rotating mechanism 10 includes a linkage shaft 101, which is rotatably connected to the winding chamber 41 and is coaxially arranged with the transmission shaft 9; the upper end of the linkage shaft 101 is driven to rotate by the transmission shaft 9, and the connecting frame 113 is installed on the outer periphery of the linkage shaft 101 and is driven to rotate by the linkage shaft 101, thereby realizing the transmission of the rotational motion, and then driving the winding of the cable 12.

[0046] The rotating mechanism 10 also includes a linkage sleeve 102 and a linkage sleeve 2 103. The rotating action of the rotating mechanism 10 is mainly achieved by the cooperation of the linkage sleeve 102 and the linkage sleeve 2 103 to realize the transmission of torque; wherein the linkage sleeve 102 is fixedly connected to the lower end position of the transmission shaft, and an axial hole 1021 is provided at the axial center position of the lower end of the linkage sleeve 102; an axial hole 2 1031 is provided at the center of the linkage sleeve 2 103, and the linkage sleeve 2 103 is sleeved on the outer periphery of the transmission shaft, and the linkage sleeve 2 103 keeps synchronous rotation with the linkage shaft 101, and can be axially slidably adjusted; specifically, the linkage shaft 101 and the linkage sleeve 2 103 can be connected by a sliding key 1033 structure, the sliding key 1033 is fixed on the outer periphery of the linkage shaft 101, and a keyway 1032 is provided in the axial hole 2 1031 of the linkage sleeve 2 103. Through the mutual cooperation of the sliding key 1033 and the keyway 1032, the linkage sleeve 2 103 can realize the sliding adjustment action on the linkage shaft 101.

[0047] In order to maintain the transmission of torque between the linkage sleeve 102 and the linkage sleeve 2 103, a slope 1022 can be set at the lower end of the linkage sleeve 102, and a slope 2 1034 can be set at the upper end of the linkage sleeve 2 103, and the slope 1022 and the slope 2 1034 are parallel to each other; the lower end of the linkage sleeve is elastically supported by the linkage spring 104, and under the action of the linkage spring 104, the linkage sleeve 2 103 can be elastically pushed upward, so that the slope 1022 and the slope 2 1034 between the linkage sleeve 102 and the linkage sleeve 2 103 are pressed against each other; Under the action of the spring 104 and the inclined plane 1022 and the inclined plane 2 1034, the torque output by the transmission shaft 9 can be transmitted downward to the linkage shaft 101, thereby driving the connecting mechanism 11 to reel in the cable 12; when the cable 12 is reeled to a relatively tight situation, relative slippage can occur between the inclined plane 1022 and the inclined plane 2 1034. When the linkage sleeve 102 continuously outputs a rotational action, the linkage sleeve 2 103 can slide downward by pushing the spring, thereby forming a limit on the reeling amplitude and maintaining the stability of the reeling of the cable 12.

[0048] The connection mechanism 11 also includes a connection sleeve 111, and a connection frame 113 is mounted on the outer periphery of the connection sleeve 111. The rotation of the connection sleeve 111 drives the movement of the connection frame 113. The connection sleeve 111 rotates synchronously with the linkage shaft 101 and can be axially slidable and adjusted. A keyway 1032 structure can also be provided between the connection sleeve 111 and the linkage shaft 101 to achieve connection.

[0049] A limit stop ring 115 is fixedly connected to the outer periphery of the upper end of the connecting sleeve 111. The limit stop ring 115 can block the lower end of the linkage spring 104, forming an elastic support structure for the lower end of the linkage spring 104; and a linkage nut 105 is threadedly connected to the lower end of the linkage shaft 101. The linkage nut 105 can be pressed against the lower end of the connecting sleeve 111 to limit the position, and provide overall support for the connecting sleeve 111 and the linkage spring 104. Before assembly, the initial pre-tightening force of the linkage spring 104 can be adjusted by adjusting the position of the linkage thread, thereby adjusting the winding tightness of the cable 12. The linkage nuts 105 can be arranged in two overlapping ways. By relative adjustment, the two linkage nuts 105 can be pressed against each other, generating pressure from the threaded parts, and then locking the position of the linkage nut 105 and the linkage shaft 101.

[0050] In the connecting mechanism 11, the connecting frame 113 can be directly fixedly connected to the outer periphery of the connecting sleeve 111, and stable synchronous transmission can be achieved between the connecting sleeve 111 and the connecting frame 113; or, a damping structure can be used to connect the connecting frame 113 and the connecting sleeve 111, so that a certain rotational damping can be formed between the connecting sleeve 111 and the connecting frame 113 bracket, and a certain range of relative rotation can be generated. When the winding is too tight, a small range of adaptive automatic adjustment can be generated to improve the overall operation stability.

[0051] like Figure 5 As shown, a driven sleeve 112 is sealed and connected to the outer periphery of the connecting sleeve 111, and a sealed damping chamber 116 is provided between the connecting sleeve 111 and the driven sleeve 112. The damping chamber 116 is filled with damping oil. The damping oil has low fluidity and can form a more stable state during the mutual rotation between the connecting sleeve 111 and the driven sleeve 112; specifically, a damping seat 117 can be fixedly connected to the outer periphery of the connecting sleeve 111 at a position corresponding to the damping chamber 116, and a damping plate 118 is provided on the outer periphery of the damping seat 117. A smaller gap is formed between the damping plate 118, the damping seat 117 and the inner wall of the damping chamber 116, so that the damping oil is more difficult to circulate, thereby maintaining the stability of the damping transmission between the driven sleeve 112 and the connecting sleeve 111.

[0052] like Figure 6 As shown, two damping seats 117 and two damping plates 118 are provided, and are distributed symmetrically around the center. A telescopic groove 119 is provided on the outer periphery of the damping seat 117, through which the damping plate 118 can be partially accommodated, so that the damping plate 118 can be adjusted to expand and contract radially along the damping cavity 116 within the range of the telescopic groove 119. When the damping plate 118 is more partially retracted into the telescopic groove 119, the gap between the edge of the damping plate 118 and the inner wall of the connecting sleeve 111 will increase, and the channel for the damping oil to flow will increase, thereby reducing the damping effect. When the damping plate 118 is pushed outward from the telescopic groove 119, the contact between the edge of the damping plate 118 and the inner wall of the connecting sleeve 111 becomes closer, and the channel for the damping oil to flow is reduced, thereby enhancing the damping effect.

[0053] The expansion and contraction of the damping plate 118 is adjusted by its own tilt, specifically, as Figure 6 As shown, a third bevel 1110 is provided on one side of the end of the damping plate 118 facing the inner circumferential wall of the driven sleeve 112, and the third bevel 1110 can be pressed and sealed against the inner circumferential wall of the driven sleeve 112; a limiting flow groove 1111 is provided on the side of the damping plate 118 facing away from the third bevel 1110, and a fourth bevel 1112 parallel to the third bevel 1110 is provided in the flow limiting groove 1111.

[0054] Under working conditions, the linkage shaft 101 drives the connecting sleeve 111 to rotate, and the rotation direction is toward one side of the flow limiting groove 1111. During the rotation, the damping oil will produce a radial component of force on the inclined surface 4 1112, which will drive the damping plate 118 to have a radial outward movement trend, and will drive the damping plate 118 and the inner circumferential wall of the driven sleeve 112 to form a tighter pressing state, forming a more stable damping state; when the linkage sleeve 102 and the linkage sleeve 2 103 are about to slide, they can reduce the wear and tear caused by long-term frequent slipping and buffering through slow damping and the continuous winding tightness of the cable 12;

[0055] Then, when the linkage shaft 101 does not rotate, in the damping chamber 116, the damping oil will form a slow pressure release on both sides of the damping plate 118, and the circulating damping oil will be easier to flow at the edge position of the inclined surface three 1110, and then a certain inward radial component force will be generated at the position of the inclined surface three 1110, so that a gap structure is easier to form between the damping plate 118 and the damping chamber 116, allowing the damping oil to automatically restore to a stable state.

[0056] Furthermore, the above embodiments can be further optimized, such as Figure 7 、 8 As shown, an elastic buffer sleeve 16 can be fixedly connected to the lower end of the driven sleeve 112, and a buffer gap 161 is formed between the elastic buffer sleeve 16 and the connecting sleeve 111. A buffer spring 163 is provided in the buffer gap 161. The buffer spring 163 can form an elastic restoring force between the elastic buffer sleeve 16 and the connecting sleeve 111, that is, during the winding action, the buffer spring 163 can stop winding the linkage shaft 101 and restore to a relatively stable state. Through the elastic action of the buffer spring 163, the torque generated during the damping movement is slowly released, thereby generating appropriate unwinding adjustment, thereby avoiding the situation where the cable 12 remains too tightly wound for a long time.

[0057] Specifically, the two ends of the buffer spring 163 are fixedly connected with buffer blocks 162 , and the buffer blocks 162 at both ends are fixedly connected to the connecting sleeve 111 and the elastic buffer sleeve 16 respectively, forming an elastic connection structure between the buffer spring 163 and the connecting sleeve 111 and the elastic buffer sleeve 16 .

[0058] In order to improve the stability of the damping rotation between the connecting sleeve 111 and the elastic buffer sleeve 16, the buffer spring 163 can be replaced by a spiral spring 164; Figure 9As shown, an elastic buffer sleeve 16 is fixedly connected to the lower end of the driven sleeve 112, and a buffer gap 161 is formed between the elastic buffer sleeve 16 and the connecting sleeve 111. A spiral spring 164 is arranged in the buffer gap 161, and buffer blocks 162 are fixedly connected to both ends of the spiral spring 164. The buffer blocks 162 at both ends are respectively fixedly connected to the connecting sleeve 111 and the elastic buffer sleeve 16, and the spiral spring 164 is wound in the buffer gap 161; the spiral spring 164 can have a larger rotation angle, thereby maintaining the stability of the damping buffering adjustment process between the connecting sleeve 111 and the elastic buffer sleeve 16, which is more conducive to the winding action of the cable 12.

[0059] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
