The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] First embodiment: like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a base station antenna phase adjustment device of the present invention includes a panel 1 and a plurality of phase shifters 2. The phase shifters 2 are evenly placed on the surface of the panel 1. The surface of the panel 1 is provided with a plurality of sliding grooves 3 on both sides of the phase shifters 2. Sliding sliders 5 are slidably installed in the sliding grooves 3. Side plates 6 are installed on the sliding sliders 5. Both sides of the phase shifters 2 are clamped and fixed inward by the side plates 6. End plates 7 are installed on the side of the side plates 6 facing the width direction of the phase shifters 2. Both ends of the phase shifters 2 are clamped and fixed inward by the end plates 7. An inclined first guide portion 8 is protruded on the outer side surface of the end plates 7. Extrusion frames 16 that drive the end plates 7 and side plates 6 to move inward are installed on both sides of the panel 1 opposite to the phase shifters 2. The side plates and end plates are stamped as a single piece, which facilitates production and reduces costs.

[0022] In this embodiment, connecting rods 10 are installed between the extrusion frames 16, and adjusting plates 11 are installed on the outermost extrusion frame 16. Connecting seats 14 are installed on the four corners of the panel 1, and screw holes are provided on the connecting seats 14. Bearings are embedded in the adjusting plates 11 at the screw holes. Screws 13 are installed in the inner rings of the bearings. One end of the screws 13 is threaded into the screw holes, and the other end is equipped with a handle 12.

[0023] In this embodiment, extrusion blocks 9 are installed at both ends of the extrusion frame 16, and each extrusion block 9 is provided with a second guide portion, which is fitted to the first guide portion 8.

[0024] In this embodiment, both the slider 5 and the slide groove 3 have a "T" shaped cross-section. A compression spring 4 is installed between the slider 5 and the slide groove 3 to prevent the slider from detaching from the slide groove, so that the end plate and the side plate can only move back and forth along the slide groove.

[0025] In this embodiment, multiple positioning holes are provided on both sides of the panel 1 opposite the extrusion frame 16. Positioning rods 18 are installed on the inner side of the extrusion frame 16 opposite the positioning holes. The other end of the positioning rods 18 is inserted into the positioning holes. The extrusion frame can be positioned by the positioning holes and positioning rods, so that the extrusion frame can only move along the positioning holes.

[0026] In this embodiment, each of the surface of the panel 1 is provided with a positioning groove 17 opposite to the phase shifter 2. Each of the phase shifters 2 protrudes to form a positioning part on the side facing the panel 1. The positioning parts are inserted into the positioning groove 17. The positioning groove and the positioning part can pre-position the phase shifter, so that the phase shifters can be evenly distributed to ensure the distance between adjacent ones.

[0027] In this embodiment, the panel 1 has fixing holes 15 at both ends, and bolts can pass through the fixing holes to fix the panel inside the base station antenna.

[0028] In this embodiment, both the side plate 6 and the end plate 7 are arranged in an "L" shape, so that one end of the side plate and the end plate forms a hook, which can hook and position the two ends of the phase shifter vertically.

[0029] In this embodiment, the side plate 6, end plate 7 and extrusion frame 16 are all made of steel, which increases the robustness and allows for a more secure clamping of the phase shifter.

[0030] A base station antenna, including the aforementioned base station antenna phase adjustment device.

[0031] Working principle: The phase shifter can be placed on the panel, and the positioning part on the phase shifter can be inserted into the positioning slot. The phase shifter can be horizontally positioned by the insertion between the positioning part and the positioning slot. After the above is completed, both hands simultaneously grasp the two handles on one side and rotate the handles. The rotation of the handles drives the screw, causing the screw to move inward along the screw hole. The movement of the screw drives the bearing and the adjusting plate, and the adjusting plate simultaneously drives the connecting rod and the extrusion frame, causing the extrusion frame to move inward along the positioning hole. The movement of the extrusion frame simultaneously drives the extrusion block, and the extrusion block, through the extrusion between the second guide part and the first guide part, can cause the end plate to move inward laterally. The movement of the end plate drives the side plate. Since both the side plate and the end plate are set in an "L" shape, the hook on the side plate can press on the surface of the phase shifter, thereby pressing and positioning the phase shifter vertically and laterally. The hook on the end plate can press on both ends of the phase shifter in the width direction, thereby positioning the phase shifter longitudinally. Conversely, after rotating the grip in the opposite direction, the extrusion frame can move outward synchronously. After the extrusion block moves away from the outside of the end plate, the rebound of the compression spring can cause the side plate and end plate to open outward synchronously, allowing the phase shifter to be directly removed upward, greatly facilitating disassembly.

[0032] Second embodiment: like Figure 5 and Figure 6 As shown, a base station antenna phase adjustment device of the present invention includes a panel 1, a plurality of phase shifters 2 and a plurality of heat sinks. The phase shifters 2 are evenly placed on the surface of the panel 1, and the heat sinks are all placed on the surface of the phase shifters 2. The surface of the panel 1 is provided with a plurality of sliding grooves 3 on both sides of the phase shifters 2. A slider 5 is slidably installed in each of the sliding grooves 3. A side plate 6 is installed on each of the sliders 5. The two sides of the phase shifters 2 and the heat sinks are clamped and fixed inward by the side plates 6. An end plate 7 is installed on the side of the side plate 6 facing the width direction of the phase shifters 2. The two ends of the phase shifters 2 are clamped and fixed inward by the end plates 7.

[0033] In this embodiment, the heat sink is composed of a heat-conducting plate 19 and multiple heat dissipation fins 20. The multiple heat dissipation fins 20 are installed on the surface of the heat-conducting plate 19. The hooks of the side plates 6 are recessed to form limiting grooves 21. The limiting grooves on each phase shifter 2 are combined to form a limiting area that matches the length and width of the heat-conducting plate 19. The heat-conducting plates 19 are placed on the surface of the phase shifter 2. The four corners of the heat-conducting plates 19 are inserted into the limiting grooves 21 and are pressed and positioned by the side plates.

[0034] In this embodiment, the heat-conducting plate 19 is made of the same material as the heat dissipation fins 20, so that the heat generated by the phase shifter can be transferred to the heat dissipation fins through the heat-conducting plate. The heat dissipation fins increase the contact area with the air, thereby quickly dissipating the heat.

[0035] During the disassembly and assembly of the phase shifter, the side plate will open outward. After the side plate moves outward, the heat conduction plate can detach from the limiting groove, which facilitates the disassembly and assembly of the heat sink and increases efficiency.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
