[0019] like Figure 1-Figure 3 As shown,

[0020] As an optional embodiment,

[0021] A communication array antenna comprises a communication array antenna board 1, a communication antenna card slot 2 is installed on the top of the communication array antenna board 1, a fixed block 3 is installed on the bottom of the communication array antenna block, a bottom plate assembly 5 is arranged below the fixed block 3, a limit assembly 4 is arranged between the bottom plate assembly 5 and the fixed block 3, the limit assembly 4 comprises a first arc block 41, a first bracket 42, a first connecting rod 43, a second arc block 44, a second bracket 45, a second connecting rod 46 and an internal threaded sleeve 47, the first arc block 41 and the second arc block 44 are located on both sides of the fixed block 3, and the first arc block 41 is fixed to the bottom plate assembly 5 through the first bracket 42, the second arc block 44 is fixed to the bottom plate assembly 5 through the second bracket 45, the inner sides of the first bracket 42 and the second bracket 45 are both hinged with a second connecting rod 46, the other ends of the second connecting rod 46 are both hinged on the internal threaded sleeve 47, and a threaded rod 52 is rotatably connected to the bottom plate assembly 5, and the top of the threaded rod 52 is inserted in the internal threaded sleeve 47 threadedly matched therewith. Specifically, multiple communication antenna slots 2 are arranged on the communication array antenna board 1, and in order to fix the communication array antenna board 1, a fixing block 3 and a limiting assembly 4 can be installed between the communication array antenna block and the base plate assembly 5. The fixing block 3 is fixed to the bottom of the communication array antenna block, and the limiting assembly 4 is fixedly connected to the base plate assembly 5. The specific structure of the limiting assembly 4 is as follows: Subsequently, the threaded rod 52 is rotated on the base plate assembly 5, thereby driving the internal threaded sleeve 47 to approach the base plate assembly 5. When the internal threaded sleeve 47 approaches the base plate assembly 5, the left and right connecting rods, namely the first connecting rod 43 and the second connecting rod 46, pull the corresponding first bracket 42 and the second bracket 45 to bend toward the center, and the centering distance between the top ends of the two brackets is continuously reduced, so that the fixing block 3 in the gap is clamped; and the spacing change of the limiting assembly 4 itself is controllable, so that the stability of the connection with the fixing block 3 is guaranteed.

[0022] like Figure 1 As shown, two fixed blocks 3 are provided under the communication array antenna board 1, and the two are symmetrically arranged about the center of the communication array antenna board 1. The same number of limit components 4 as the fixed blocks 3 are installed between the bottom plate component 5 and the fixed block 3. Each limit component 4 corresponds to a fixed block 3, and the bottom of each limit component 4 is fixedly connected to the bottom plate component 5, and the top of the limit component 4 is clamped on both sides of the fixed block 3. The corresponding multiple limit components 4 and the fixed block 3 can further ensure the stability of the overall force.

[0023] like Figure 1 As shown, the fixing block 3 is welded to the communication array antenna board 1 as a whole, and the fixing block 3 is fixed to the communication array antenna board 1 by welding, which can ensure that the fixing block 3 and the communication array antenna board 1 are integrated and will not separate from each other.

[0024] like Figure 1 and Figure 2As shown, arc grooves are provided on both sides of the two fixing blocks 3 to cooperate with the first arc block 41 and the second arc block 44 respectively. In order to ensure that the arc block and the fixing block 3 can be engaged with each other during subsequent positioning, arc grooves are provided on both sides of each fixing block 3 to cooperate with the left and right arc blocks, namely the first arc block 41 and the second arc block 44, to clamp and fix. In this process, the original contact area can be increased to further ensure that the two will not separate from each other due to external force.

[0025] like Figure 3 As shown, the base plate assembly 5 includes a box body 51, which is provided with a first through hole 511. The bottom of the threaded rod 52 passes through the first through hole 511 and enters the interior of the box body 51, and one end is fixedly connected to a worm gear 53. A worm 54 meshing with the worm gear 53 is horizontally installed in the box body 51, and both ends of the worm gear 54 are connected to two opposite inner walls of the box body 51 through bearing seats 55. The rotation of the threaded rod 52 is completed by the cooperation of the worm gear 53 and the worm 54, and the driving is more convenient. In addition, the cooperation between the worm 54 and the worm wheel 53 can prevent the threaded rod 52 from rotating on its own.

[0026] like Figure 3 As shown, a second through hole 512 is opened on the box body 51 for the end of the worm 54 to pass through, and a knob 6 is installed at the end of the worm 54 passing through the second through hole 512. In order to facilitate the rotation of the threaded rod 52, a rotating knob 6 is subsequently installed to allow the worm 54 to rotate in the box body 51.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
