The setting of the connecting rod 92 is fixedly connected to the inner wall of the inner ring of the bearing 91, and the outer wall of the bearing 91 is fixedly connected to the fixed chassis 1, thereby increasing the continuity of the signal receiving device during rotation. At the same time, the setting of the steel ball 94 in conjunction with the use of the bearing 91 increases the continuity of the signal receiving device during rotation while also ensuring the stability of the signal receiving device during rotation.

[0022] Working principle: In actual life use, when the signal receiving device is looking for digital signals, first fix the entire fixed chassis 1 to the place of use by bolts to ensure the stability of the entire signal receiving device. The fixed chassis 1 is used to fix the satellite dish at a certain position. The parabola dish body 2 is a parabola shape, which can receive signals from the satellite. The parabola can reflect the incident light parallel to the axis to a focus, thereby enhancing the signal strength. When the fixed chassis 1 is fixed, the fixed chassis 1 firmly fixes the entire signal receiving device for digital broadcasting and television engineering through the bearing 91 and the connecting rod 92, avoiding the external environment from causing deviation to the entire signal receiving device. When the signal receiving device needs to find a digital signal, first lift the collar 14, the ring 14 drives the limiting rod 15 to move upward, so that the limiting rod 15 is disengaged from the limiting hole 95. At this time, the bracket 3 is disengaged from the restriction of the limiting rod 15, and then the handle 13 is rotated outward. The movement of the handle 13 drives the adjusting rod 12 to move out from the inside of the limiting slot 810, so that the adjusting rod 12 is disengaged from the restriction of the limiting slot 810. At this time, the spring 87 releases the restriction and releases the elasticity, thereby pushing the limiting sleeve 85 to move toward the inside of the support sleeve 83. The limiting sleeve 85 also drives the limiting tooth ring 86 to disengage from the inside of the adjusting tooth hole 82, so that the limiting tooth ring 86 and the adjusting tooth hole 82 are no longer engaged, thereby releasing the adjustment frame 81 from the restriction. At this time, the adjusting rod 12 is rotated by the handle 13, and the adjusting rod 12 enables the parabolic pot body 2 to move vertically through the tray 4. At the same time, by rotating the adjustment rod 12 left and right, the adjustment rod 12 drives the bracket 3 to rotate through the tray 4 and the bracket 3, and is fixedly connected to the inner wall of the inner ring of the bearing 91 through the provided connecting rod 92, and the outer wall of the bearing 91 is fixedly connected to the fixed chassis 1, thereby increasing the continuity of the signal receiving device during rotation. At the same time, by using the provided steel ball 94 in conjunction with the bearing 91, while increasing the continuity of the signal receiving device during rotation, it also ensures the stability of the signal receiving device during rotation. Through the above-mentioned arrangement, the parabolic dish body 2 can move in the vertical direction and can also rotate and move, thereby improving the angle adjustment of the signal receiving dish when the signal receiving device is searching for a digital signal. When the signal receiving device finds a digital signal, firstly, the handle 13 is used to adjust the angle of the signal receiving dish. Keep the position of the adjusting rod 12 unchanged. At this time, pinch the two limit blocks 88 to move the two limit blocks 88 toward the middle, so that the limit slots 810 on the surfaces of the two limit blocks 88 are on the same vertical line. At this time, the limit block 88 drives the limit tooth ring 86 to move toward the direction of the adjusting tooth hole 82 through the limit sleeve 85. When the limit slots 810 on the surfaces of the two limit blocks 88 are on the same vertical line, the limit tooth ring 86 and the adjusting tooth hole 82 are engaged. At this time, put the adjusting rod 12 into the two limit slots 810, so as to limit the limit blocks 88 to the left and right, so that the parabolic pot body 2 cannot move in the vertical direction, and then push down the ring 14, the ring 14 drives the limit rod 15 to move downward, so that the limit rod 15 is inserted into the limit hole 95.At this time, the bracket 3 is limited by the limit rod 15, so that the parabolic dish body 2 cannot move in the rotation direction. At this point, the signal receiving device completes the search for digital signals. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
