Detailed Description

For the purpose of making apparent the objects, technical solutions and advantages of the present utility model, the present utility model will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present utility model and the descriptions thereof are for illustrating the present utility model only and are not to be construed as limiting the present utility model.

The inventor finds that when the active phased array antenna debugging device is frequently used indoors and outdoors, the existing active phased array antenna debugging device is troublesome to disassemble and complex to operate, so that time and labor are wasted and the working difficulty is increased.

In view of the above problems, the present inventors have found that there is a certain difference between indoor and outdoor when using an active phased array antenna commissioning device, specifically: when the device is used indoors (by using a laboratory table or a debugging platform), a bracket is not needed, and when the device is used outdoors, the bracket is needed; therefore, the inventor connects the bracket and other parts in a detachable way, the other parts are connected into a whole, the bracket and the other parts can be separated for carrying, and the connection of the bracket and the other parts is realized by adopting a loose and non-release connecting piece, so that the independent storage of the connecting piece can be avoided, and the connection can be realized quickly by only screwing the loose and non-release connecting piece, thereby bringing the effects of simple operation and time saving.

As shown in fig. 1, the embodiment of the utility model provides an in-field and out-of-field debugging device for an active phased array antenna. As shown in fig. 1-2, the active phased array antenna in-field and out-of-field debugging device comprises a support 1, wherein the support 1 is detachably connected with a conversion base 3 through a loose and non-detachable connecting piece 2. It should be noted that: the "loose-fitting-preventing-member-2" means that the conversion base 3 and the bracket 1 can be detachably connected (as shown in fig. 8), but when the bracket 1 and the conversion base 3 are separated, the loose-fitting-preventing-member-2 can be left on the conversion base 3 or the bracket 1 and cannot fall off, so that the loose-fitting-preventing-member-2 does not need to be separately stored; for example, the loose screw is not removed, and is fixed on the bracket 1 through a threaded hole, and the free end of the loose screw is screwed into the conversion base 3 to realize the detachable connection of the loose screw and the conversion base. For indoor and outdoor debugging, only the loose connecting piece 2 is required to be detached and the loose connecting piece 2 is left on the conversion base 3 or the bracket 1, the separation of the loose connecting piece 2 and the conversion base 3 is realized through one-step operation, and the indoor and outdoor debugging device can be completely suitable for frequent indoor and outdoor switching and is high in practicability.

The angle adjusting mechanism 4 comprises two opposite lugs 401 rotatably connected to the conversion base 3, scale marks 301 are arranged on the conversion base 3, a pointer 402 for indicating scales is arranged on at least one lug 401, and the free end of each lug 401 is connected with the conversion base 3 through a locking component 403.

As shown in fig. 6 and 7, the antenna 5 is mounted by being placed between two opposite lugs 401 and connected to the two lugs 401, and thus, it is known that the mounting operation of the antenna 5 is also simple. By loosening the locking part 403 and then rotating the lug 401 around the rotation connection point, in this process, the lug 401 drives the antenna 5 to adjust in angle, and when the pointer 402 points to the required scale, the lug 401 stops rotating, and the lug 401 can be fixed by tightening the locking part 403. The angle adjusting mode is simple and easy to implement, and the angle is stable after adjustment. Because the support lug 401 is rotatably connected to the conversion base 3, the support lug 401 can rotate at a large angle, so that the pitching angle of the antenna 5 can be adjusted, and the use and maintenance are convenient.

It should be noted that, the "locking member 403" may be a member that is commonly used in the art to detachably connect two members and is fixedly connected after connection, for example: and (5) a bolt.

In one possible embodiment, as shown in fig. 4, the locking member 403 includes a hand-held portion, and a screw is connected to one end of the hand-held portion, and the screw is screwed with the lug 401. When the angle of the support lug 401 needs to be adjusted, the hand-held part is held and rotated, at this time, the free end of the screw is screwed out of the threaded hole of the support lug 401, separation of the support lug 401 and the locking part 403 is achieved, then the support lug 401 is held by hand so that the support lug rotates around the rotation connecting point and rotates to a corresponding angle, and finally the locking part 403 is screwed to achieve connection of the support lug 401 and the locking part 403, so that fixation of the support lug 401 is achieved.

In one possible embodiment, as shown in fig. 3, the conversion base 3 includes two side plates 302 that are connected to each other and disposed opposite to each other, a support plate 303 is disposed between the two side plates 302, the scale marks 301 are disposed on at least one side plate 302, and a height adjusting screw 304 is disposed on each side plate 302.

The arc-shaped through hole 305 is provided mainly for mounting the locking member 403, avoiding the need to separately house the locking member 403 when the antenna 5 is not mounted. When the lug 401 rotates, the pointer 402 rotates along with the lug, and when the indication end of the pointer 402 reaches the corresponding indication position, the rotation of the lug 401 is stopped.

In one possible embodiment, as shown in fig. 3, the supporting plate 303 is provided with a viewing hole 306. When directly connected with the adapter base, the bracket 1 is observed whether to be adjusted to be horizontal or not through the observation hole 306 or the adjustment process is observed until the bracket is adjusted to be horizontal.
