[0032] At present, the fixing mode of most pull rods and adapters is screw fixing, however, the screw fixing installation is more cumbersome, and the normal process needs pre-tightening, and then tightening, the more the number of phase shifters, the more likely it is to appear not to be tightened, so that the pull rod and the adapter are not tightly fixed and a virtual position is generated, which may seriously or cause the screw to fall off, so that the phase shifter cannot adjust the angle, and the antenna angle adjustment is invalid; at the same time, the screw fixing is at risk of loosening and falling off, and needs regular inspection and maintenance.

[0036] According to the phase shift device provided by the embodiment of the utility model, first, one end of pull rod 200 is connected with phase shifter 100, the other end of pull rod 200 is fixed with one end of adapter 300 through connecting piece 400, drive assembly 500 is connected with the other end of adapter 300 to drive pull rod 200 to pull phase shifter 100, phase adjustment is realized, so that the desired signal radiation range is achieved;Second, compared with the scheme that complex groove structure is arranged on adapter 300 and pull rod 200 to cooperate with the embedding of connecting piece 400, only a plurality of through holes 10 are provided on the attachment surface of adapter 300 and pull rod 200, two guide columns 420 and first buckle 430 in connecting piece 400 are inserted into the through hole 10 of adapter 300 and pull rod 200, the positioning and fastening of adapter 300 and pull rod 200 are realized, the processing process of adapter 300 and pull rod 200 is simplified, and the assembly efficiency of phase shift device is improved;In addition, the positioning and fastening of adapter 300 and pull rod 200 are realized by connecting piece 400, which replaces the traditional screw fixing mode, saves the cumbersome steps of screw assembly, simplifies the workshop mass production process, and significantly improves the assembly efficiency of phase shift device;At the same time, it also effectively avoids the loosening and falling problem caused by the negligence of production line staff in the assembly process.

[0037] Preferably, the through hole 10 can be cylindrical or square column, and the shape of the through hole is not limited in the application.

[0038] It should be noted that the integrated processing method can be used to drill the connecting surface of the adapter 300 and the pull rod 200 at one time, thereby improving the processing efficiency.

[0039] It can be understood that the design of the through hole 10 enables the connecting piece 400 to be easily inserted, thereby achieving rapid positioning and fastening of the adapter 300 and the pull rod 200, reducing the assembly time and difficulty, and improving the production efficiency.

[0040] It can be understood that the guide column 420 can help the connecting piece 400 to be quickly and accurately installed on the connecting surface of the pull rod 200 and the adapter, thereby reducing the assembly difficulty.

[0041] Preferably, the first buckle piece 430 can be arranged between the two guide columns 420, and the position of the first buckle piece 430 is not limited in the present application.

[0042] In some embodiments, referring to Figure 3 、 Figure 4 , the first buckle piece 430 includes a first column 431, a second column 432, and at least one first elastic piece 433, one end of the first column 431 is connected with the inner surface of the panel 410, the other end of the first column 431 is connected with one end of the second column 432, the first elastic piece 433 is arranged on the second column 432, the first column 431 and the second column 432 are inserted into the through hole 10 of the adapter 300 and the pull rod 200, the first elastic piece 433 abuts against the back surface of the adapter 300, and the cross-sectional area of the first column 431 is greater than that of the second column 432.

[0043] It should be noted that when the first column 431 and the second column 432 of the first buckle piece 430 are inserted into the through hole 10 of the adapter 300 and the pull rod 200, the first elastic piece 433 on the second column 432 is in a contracted state under the extrusion of the side wall of the through hole 10; after passing through the through hole 10, the first elastic piece 433 is in an expanded state and abuts against the back surface of the adapter 300, thereby achieving the fixed connection of the pull rod 200 and the adapter 300; in addition, by applying a certain external force to the first elastic piece 433, the first elastic piece 433 can be changed to a contracted state, thereby being quickly disassembled from the front direction of the pull rod 200, which is conducive to speeding up the maintenance and updating of the accessories in the phase-shifting device.

[0044] It should be noted that under the extrusion of the side wall of the through hole 10, the first elastic piece 433 can be contracted and tightly attached to the side wall of the second column 432, thereby quickly passing through the through hole 10; or a groove is arranged in the second column 432, and under the extrusion of the side wall of the through hole 10, the first elastic piece 433 can be contracted and embedded in the groove in the second column 432, thereby quickly passing through the through hole 10.

[0045] It should be noted that when the first elastic member 433 is in the relaxed state, the cross-sectional area of the fastening structure formed after the first elastic member 433 is connected with the second column 432 is greater than the hole diameter of the through hole 10, and therefore the first elastic member 433 can stably abut against the back surface of the adapter 300, achieving fixed connection of the pull rod 200 and the adapter 300.

[0046] It can be understood that, referring to Figure 3 When the first clamping member 430 includes a plurality of first elastic members 433, the plurality of first elastic members 433 are uniformly arranged on the side wall of the second column 432; under the extrusion of the side wall of the through hole 10, the plurality of first elastic members 433 can be contracted and tightly attached to the side wall of the second column 432, so as to quickly pass through the through hole 10; or a plurality of grooves are arranged in the second column 432, and under the extrusion of the side wall of the through hole 10, the plurality of first elastic members 433 can be contracted and embedded in the plurality of grooves in the second column 432, so as to quickly pass through the through hole 10.

[0047] It can be understood that the cross-sectional area of the first column 431 is greater than the cross-sectional area of the second column 432, which on the one hand can make the overall structure of the first clamping member 430 more compact, and on the other hand is conducive to saving production materials of the first clamping member 430 and reserving space for arranging the first elastic member 433, reducing production cost and improving the fixing effect of the first clamping member 430.

[0048] In some embodiments, referring to Figure 5 , the first clamping member 430 includes a third column 434 and a second elastic member 435, the top of the third column 434 is connected with the inner surface of the panel 410, the second elastic member 435 is arranged at the bottom of the third column 434, the third column 434 is inserted into the through hole 10 of the adapter 300 and the pull rod 200, the second elastic member 435 abuts against the back surface of the adapter 300, and the cross-sectional area of the top and the bottom of the third column 434 is smaller than the cross-sectional area of the middle part of the third column 434.

[0049] Preferably, the third column 434 is elliptical, and the shape of the third column 434 is not limited in the present application.

[0050] It should be noted that when the third column 434 in the first buckle 430 is inserted into the through hole 10 in the adapter 300 and the pull rod 200, the second elastic member 435 at the bottom of the third column 434 is in a contracted state under the pressure of the side wall of the through hole 10; after passing through the through hole 10, the second elastic member 435 is in an extended state and abuts against the back of the adapter 300, thereby fixing the pull rod 200 and the adapter 300 together; in addition, by applying a certain external force to the second elastic member 435, the second elastic member 435 can be made to retract, and can be quickly removed from the front of the pull rod 200, which is beneficial to speeding up the maintenance and replacement of the components in the phase shifting device.

[0051] It should be noted that, under the pressure of the sidewall of the through hole 10, the second elastic element 435 can shrink and adhere to the sidewall of the third column 434, thereby quickly passing through the through hole 10; or, a groove is provided in the third column 434, and under the pressure of the sidewall of the through hole 10, the second elastic element 435 can shrink and be embedded in the groove in the second column 432, thereby quickly passing through the through hole 10.

[0052] It should be noted that when the second elastic member 435 is in the extended state, the maximum cross-sectional area of ​​the fastening structure formed by the second elastic member 435 and the third column 434 is greater than the diameter of the through hole 10. Therefore, the second elastic member 435 can be stably abutted against the back of the adapter 300 to achieve a fixed connection between the pull rod 200 and the adapter 300.

[0053] It is understandable that the cross-sectional areas of the top and bottom of the third column 434 are smaller than the cross-sectional area of ​​the middle part of the third column 434. On the one hand, this makes the overall structure of the first fastener 430 more compact. On the other hand, it helps to save the raw materials for the production of the first fastener 430 and to reserve space for the first elastic element 433, thereby reducing production costs and improving the fixing effect of the first fastener 430.

[0054] In some embodiments, refer to Figure 6 , Figure 9 , Figure 10 , Figure 11 It also includes a second fastener 440, which is disposed on the inner surface of the panel 410. The first fastener 430 and the second fastener 440 are separated by a first distance. The second fastener 440 is inserted into the through hole 10 of the adapter 300 and the pull rod 200, and the second fastener 440 abuts against the back of the adapter 300.

[0055] It should be noted that, compared to the solution of setting a single fastener, both the first fastener 430 and the second fastener 440 are inserted into the through holes 10 of the adapter 300 and the pull rod 200, and both the first fastener 430 and the second fastener 440 abut against the back of the adapter 300, forming a multi-point fixation, which improves the stability and service life of the connector 400. Especially when it needs to withstand greater external force or vibration, it can more effectively prevent the adapter 300 or the pull rod 200 from moving or falling off unexpectedly.

[0056] Preferably, the first fastener 430 and the second fastener 440 are both disposed between the two guide posts 420. In this application, the placement of the first fastener 430 and the second fastener 440 is not limited in too much.

[0057] Preferably, the second fastener 440 has the same size and structure as the second fastener 432. The second fastener 440 includes a first column 431, a second column 432, and at least one first elastic member 433. One end of the first column 431 is connected to the inner surface of the panel 410, and the other end of the first column 431 is connected to one end of the second column 432. The first elastic member 433 is disposed on the second column 432. Both the first column 431 and the second column 432 are inserted into the through hole 10 of the adapter 300 and the pull rod 200. The first elastic member 433 abuts against the back of the adapter 300. The cross-sectional area of ​​the first column 431 is larger than the cross-sectional area of ​​the second column 432.

[0058] Preferably, the second fastener 440 has the same size and structure as the second fastener 440. The second fastener 440 includes a third column 434 and a second elastic member 435. The top of the third column 434 is connected to the inner surface of the panel 410. The second elastic member 435 is disposed at the bottom of the third column 434. The third column 434 is inserted into the through hole 10 of the adapter 300 and the pull rod 200. The second elastic member 435 abuts against the back of the adapter 300. The cross-sectional areas of the top and bottom of the third column 434 are both smaller than the cross-sectional area of ​​the middle part of the third column 434.

[0059] In some embodiments, refer to Figure 6 The first buckle 430 and the second buckle 440 have the same size and structure. The first buckle 430 includes a vertical member 436 and a barb 437. One end of the vertical member 436 is connected to the inner surface of the panel 410, and the other end of the vertical member 436 is connected to the barb 437. The vertical member 436 is inserted into the through hole 10 of the adapter 300 and the pull rod 200, and the barb 437 abuts against the back of the adapter 300.

[0060] It is understandable that the vertical member 436 in the first snap fastener 430 and the vertical member 436 in the second snap fastener 440 are separated by a first distance. When the vertical member 436 is inserted into the through hole 10 of the adapter 300 and the pull rod 200, the barb 437 at the other end of the vertical member 436 deforms under the pressure of the side wall of the through hole 10 and abuts against the side wall of the through hole 10. After passing through the through hole 10, the second elastic member 435 is in an extended state and abuts against the back of the adapter 300, thereby fixing the pull rod 200 and the adapter 300 together. The installation process is simple and quick. In addition, by applying a certain external force to the barbs of the first snap fastener 430 and the second snap fastener 440 at the same time, the barb 437 can be deformed and embedded into the through hole 10, and the pull rod 200 can be quickly removed from the front side, which is beneficial for the maintenance and replacement of the accessories in the phase shifting device.

[0061] In some embodiments, refer to Figures 3-11 The connector 400 also includes two side plates 450, which are disposed opposite to each other on both sides of the panel 410. The two side plates 450 are used to limit the pull rod 200. The length of the first buckle 430 is greater than the length of the two guide posts 420.

[0062] It should be noted that when the connector 400 fixes the pull rod 200 and the adapter 300, the panel 410 of the connector 400 is close to the front of the pull rod 200, the back of the pull rod 200 is close to the front of the adapter 300, the two guide posts 420 and the first buckle 430 are inserted into the through hole 10 of the adapter 300 and the pull rod 200, and the first buckle 430 abuts against the back of the adapter 300.

[0063] Furthermore, two side plates 450 are disposed opposite to each other on both sides of the panel 410. The two side plates 450 are used to limit the pull rod 200, which can effectively limit the lateral displacement of the pull rod 200, so that the pull rod 200 and the adapter 300 are kept aligned, avoiding assembly or functional problems caused by displacement. In addition, the two side plates 450 can serve as gripping points to help the assembler insert the connector 400 into the through hole 10 of the adapter 300 and the pull rod 200 more stably, especially in narrow or inconvenient spaces. Moreover, the two side plates 450 can cover the gap between the front of the pull rod 200 and the inner surface of the panel 410 of the connector 400, preventing the assembler's fingers from accidentally entering the dangerous area and avoiding being pinched or pressed during the fastening process.

[0064] In some embodiments, refer to Figure 1 , Figure 2 The drive assembly 500 includes a motor, a screw connected to the motor, and a sliding block sleeved on the screw. The sliding block is fixedly connected to the other end of the adapter 300 through a connector 400.

[0065] It should be noted that, referring to Figure 9 , Figure 10 , Figure 11 Multiple through holes 10 are also provided at the other end of the adapter 300. At the same time, corresponding through holes 10 are also provided in the sliding block. The two guide posts 420 of the connector 400 and the first buckle 430 are all inserted into the through holes 10 of the adapter 300 and the sliding block. The first buckle 430 abuts against the back of the adapter 300.

[0066] Preferably, there are two phase shifters 100, two pull rods 200, two sliding blocks, two adapters 300, and two screws. Each pull rod 200 connects one adapter 300 to one phase shifter 100. In this application, there are no excessive limitations on the number of phase shifters 100, pull rods 200, sliding blocks, adapters 300, and screws.

[0067] Furthermore, in the drive assembly 500, the motor is connected to two screws, and a sliding block is fitted on top of each screw. The sliding block is connected to the adapter 300. The drive assembly 500 is located in the middle of the two phase shifters 100, making the overall structure more compact. Moreover, the drive assembly 500 can simultaneously drive the two pull rods 200 to adjust the phase of the two phase shifters 100, thus shortening the phase adjustment time.

[0068] In some embodiments, refer to Figure 1 , Figure 2 Phase shifter 100 is a fan-shaped phase shifter or a cavity phase shifter.

[0069] In some embodiments, the connector 400 is made of plastic material.

[0070] Understandably, the use of plastic material for connector 400 results in a lighter weight, which helps reduce the overall weight of the phase shifting device and facilitates installation and transportation.

[0071] In some embodiments, refer to Figure 7 , Figure 8 The adapter 300 is a square block structure or a long strip rod structure.

[0072] Understandably, the adapter 300 is a square block structure or a long rod structure, which has high rigidity and stability and can provide good structural support.

[0073] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
