DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0026] First embodiment

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a clamping device for a satellite antenna provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the fixed ring structure shown; Figure 3 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 4 for Figure 2 The enlarged schematic diagram of part B is shown. A clamping device for a satellite antenna comprises: a fixing ring 1;

[0028] A first rotating seat 11, the first rotating seat 11 is fixedly installed on three sides of the fixed ring 1, the inner side surface of the first rotating seat 11 is rotatably connected to a fixed rod 2, the inner side surface of the fixed rod 2 is slidably connected to an extension rod 23, one end of the extension rod 23 is fixedly installed with a second rotating seat 24, the inner side surface of the second rotating seat 24 is rotatably connected to a clamping plate 25, both sides of the fixed rod 2 are provided with a slide groove 22, the inner side surface of the slide groove 22 is slidably connected to a limit rod 23, and the limit rod 23 is fixedly installed on the other end of both sides of the extension rod 21;

[0029] The mounting rod 3 is fixedly mounted on the inner side surface of the fixing ring 1, the inner side surface of the mounting rod 3 is slidably connected with a sliding rod 31, the inner side surface of the sliding rod 31 is threadedly connected with a threaded rod 33, the bottom of the threaded rod 33 is fixedly mounted with a rotating handle 34, and the bottom of the rotating handle 34 is rotatably connected with a pushing plate 35.

[0030] A locking screw 32 is connected to the inner thread of the bottom of one side of the mounting rod 3 .

[0031] One end of the locking screw 32 is disposed on one side of the sliding rod 31 .

[0032] The top and bottom of the limiting rod 23 are respectively fitted with the top and bottom of the sliding groove 22 , and the limiting rod 23 is square.

[0033] When the extension rod 21 slides on the inner side of the fixed rod 2, the limiting rod 23 slides on the inner side of the slide groove 22, so that the limiting rod 23 can be limited to prevent the limiting rod 23 from rotating; and by sliding the extension rod 21 on the inner side of the fixed rod 2, antennas of different sizes can also be clamped, thereby increasing the adaptability of the device;

[0034] By rotating the handle 34 , the handle 34 drives the threaded rod 33 to be threadedly connected to the inner side of the sliding rod 31 , so that the push plate 35 can be pressed against the antenna, thereby increasing the clamping force and thus increasing the clamping stability.

[0035] The working principle of a clamping device for a satellite antenna provided by the utility model is as follows:

[0036] When the antenna needs to be clamped, the user clamps the three clamping plates 25 on the edge of the antenna, and then the user pulls the sliding rod 31 so that one end of the sliding rod 31 drives the threaded rod 33, the rotating handle 34 and the pushing plate 35 to move toward one side of the antenna. When the pushing plate 35 is moved to one side of the antenna, the fixing ring 1 will be pushed toward the end away from the antenna, at which time the extension rod 21 will move out from the inner side surface of the fixing rod 2 until one end of the limiting rod 23 abuts against one end of the inner side surface of the sliding groove 22, and the pushing plate 35 and the antenna are fitted together. Then the user rotates the locking screw 32 so that the locking screw 32 is threadedly connected inside the mounting rod 3, so that one end of the locking screw 32 abuts against the sliding rod 31, thereby limiting the mounting rod 3 and the sliding rod 31, and then the user rotates the rotating handle 34 so that the rotating handle 34 drives the threaded rod 33 to be threadedly connected to the inner side surface of the sliding rod 31, thereby strengthening the abutment force between the pushing plate 35 and the antenna and increasing the strength of the antenna clamping.

[0037] Compared with the related art, the clamping device for satellite antenna provided by the utility model has the following beneficial effects:

[0038] By means of the cooperation of structures such as the fixing ring 1, the fixing rod 2, the extension rod 21, the clamping plate 25, the mounting rod 3, the sliding rod 31, the locking screw 32, the threaded rod 33, the turning handle 34 and the pushing plate 35, when clamping the antenna, the user only needs to clamp the clamping plate 25 on the edge of the antenna, and then pull the sliding rod 31 so that the sliding rod 31 lifts the fixing ring 1 away from the antenna, and then rotates the locking screw 32 to enable the clamping frame 25 to clamp the antenna, thereby reducing the operation steps and increasing the work efficiency.

[0041] Specifically, the second embodiment of the present application provides a clamping device for a satellite antenna, which is different in that, in a clamping device for a satellite antenna, the outer side surface of the push plate 35 is threadedly connected with a thread ring 4, and a through groove 41 is formed at the bottom of the thread ring 4.

[0042] A rubber pad 42 is disposed at the bottom of the push plate 35 , and the rubber pad 42 is disposed on the inner side of the thread ring 4 .

[0043] The bottom of the rubber pad 42 extends to the bottom of the threaded ring 4 .

[0044] The working principle of a clamping device for a satellite antenna provided by the utility model is as follows:

[0045] When in use, the user can place the rubber pad 42 on the bottom of the pushing plate 35, and then the user places the threaded ring 4 on the bottom of the pushing plate 35, and then the user passes the through groove 41 opened at the bottom of the threaded ring 4 through the outer side of the rubber pad 42, and then the threaded ring 4 is threadedly connected to the outer side of the pushing plate 35, and then the threaded ring 4 and the rubber pad 42 are installed. When in use later, the rubber pad 42 is placed between the pushing plate 35 and the antenna.

[0046] Compared with the related art, the clamping device for satellite antenna provided by the utility model has the following beneficial effects:
