[0026] Figure 4 It is a structural schematic diagram of an embodiment of a loading sheet installation device in the present invention. DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0028] like Figure 1 As shown, the present invention provides an antenna, which includes a radiation unit assembly, and the radiation unit assembly includes a loading plate mounting device 1, a loading plate 2 and a radiation unit 3, and the loading plate mounting device 1 is used to mount the loading plate 2 above the radiation unit 3.

[0029] Combination Figure 2 As shown, the loading sheet installation device 1 includes a main body 11, and at least two installation slots 111 for inserting the loading sheet 2 are provided on the main body 11 along the vertical arrangement direction, and the bottom of the main body 11 is used to be insulated and connected to the radiation unit 3. In this embodiment, three installation slots 111 are provided, and in other embodiments, the installation can also be set to more than three.

[0030] Specifically, the main body 11 includes a bottom plate 112 and two side plates 113 connected to the bottom plate 112 and arranged opposite to each other. Preferably, the two side plates 113 are arranged parallel to each other, and the bottom plate 112 is used to be insulated and fixed to the radiation unit 3. The mounting grooves 111 are arranged opposite to each other on the side walls of the two side plates 113.

[0031] By arranging a plurality of installation grooves 111 in the vertical direction for inserting the loading piece 2, a variety of height options are provided for the installation of the loading piece 2, thereby improving the convenience and applicability of installing the loading piece 2. Compared with the existing plastic clips, the trouble of replacement is reduced, the types are also reduced, and the production cost and time cost are reduced.

[0032] Furthermore, a stop wall 1111 is provided at one end of the installation slot 111. Preferably, the stop walls 1111 of the three installation slots 111 on the side plate 113 are located at the same end, that is, the insertion directions of the three loading sheets 2 are consistent. By providing the stop wall 1111 at one end of the installation slot 111, when the loading sheet 2 is inserted into the installation slot 111, it stops at the stop wall 1111, providing a limiting effect for the installation of the loading sheet 2, and improving the installation stability of the loading sheet 2.

[0033] Furthermore, at least two elastic arms 114 are provided between the two side plates 113 along the vertical direction, and the two ends of the elastic arms 114 are respectively connected to the side plates 113 in an integral manner, and the number of the elastic arms 114 is consistent with the number of the mounting slots 111. In this embodiment, three elastic arms 114 are provided, and the elastic arms 113 correspond to the mounting slots 111 one by one. A positioning hole 21 is provided in the middle of the loading sheet 2, and a positioning block 115 that can be inserted into the positioning hole 21 is provided on the elastic arm 113. Specifically, a guide surface is provided on the side of the positioning block 115 away from the stop wall 1111.

[0034] In this embodiment, each of the elastic arms 114 is correspondingly disposed above each of the mounting slots 111, and the positioning block 115 is disposed below the elastic arm 114. In other embodiments, the elastic arm 114 may also be disposed below the mounting slot 111, and the positioning block 115 may be disposed above the elastic arm 114.

[0035] When the loading sheet 2 is inserted into the mounting groove 111, the loading sheet 2 and the guide surface of the positioning block 115 assist and drive the positioning block 115 to move upward, the elastic arm 114 undergoes elastic bending and deformation, the positioning block 115 penetrates into the positioning hole 21, and the elastic arm 114 elastically resets. The cooperation between the positioning block 115 and the positioning hole 21 on the loading sheet 2 prevents the loading sheet 2 from escaping from the mounting groove 111, thereby improving the connection reliability between the loading sheet 2 and the loading sheet mounting device 1.

[0036] Combination Figure 3 As shown, preferably, the bottom surface of the elastic arm 114 is flush with the top wall of the mounting groove 111. When the loading piece 2 is inserted into the mounting groove 111, the upper surface of the loading piece 2 abuts against the elastic arm 114, increasing the contact area between the loading piece 2 and the loading piece mounting device 1, and further improving the connection reliability between the loading piece 2 and the loading piece mounting device 1.

[0037] Combination Figure 4As shown, in this embodiment, the bottom plate 112 includes a central portion 1121 and four extension portions 1122 centrally symmetrically connected to the central portion 1121. Specifically, the central portion 1121 and the four extension portions 1122 form a cross shape. A pair of hooks 1123 that can be hooked and fixed on the radiation unit 3 are provided below the extension portion 1122. Specifically, the hooks 1123 are hooked on a pair of baluns of the radiation unit 3.

[0038] The hook 1123 is hooked onto the radiation unit 3 to limit the loading piece installation device 1 in the vertical direction to prevent the loading piece installation device 1 from loosening and falling off due to external environmental factors.

[0039] A positioning rib 1124 that can be inserted into the balun slot of the radiation unit 3 is provided below the extension portion 1122. Specifically, the balun slot is the gap between two balun arms that constitute a balun of the radiation unit 3. In this embodiment, the positioning rib 1124 is provided in the middle of the extension portion 1122 and extends along the length direction of the extension portion 1122. A hook 1123 is provided on each side of the positioning rib 1124. On the one hand, the positioning rib 1124 can be inserted between the balun slots to provide horizontal limitation for the radiation unit 3. On the other hand, the positioning rib 1124 can also calibrate the size of the balun slot to ensure the accuracy of the size of the balun slot.

[0040] Furthermore, a pair of limit blocks 1125 are provided below the extension portion 1122 and are arranged parallel to each other and can be horizontally clamped on the radiation unit 3. The two limit blocks 1125 are arranged on both sides of the positioning rib 1124. Preferably, an inclined surface is provided on one side of the limit block 1125 close to the positioning rib 1124.

[0041] The limiting blocks 1125 are clamped on both sides of a pair of baluns in the radiation unit 3 to limit the loading sheet mounting device 1 in the horizontal direction, thereby further improving its installation stability.

[0042] In summary, the solution of the present invention has the following advantages:

[0043] 1. In the loading piece installation device 1 of the present invention, by arranging a plurality of installation slots 111 for inserting the loading piece 2 in the vertical direction, a variety of height options are provided for the installation of the loading piece 2, thereby improving the convenience and applicability of installing the loading piece 2. Compared with the existing plastic clips, the trouble of replacement is reduced, the types are also reduced, and the production cost and time cost are reduced.

[0044] 2. In the loading piece installation device 1 of the present invention, the positioning block 115 cooperates with the positioning hole 21 on the loading piece 2, so that the installation of the loading piece 2 and the loading piece installation device 1 is more secure, simple in structure, low in cost, and can achieve a better fastening effect.

[0045] 3. In the radiation unit assembly involved in the present invention, by adopting the above-mentioned loading plate installation device 1, the structure of the radiation unit assembly is more standardized, a variety of height options are provided for the installation of the loading plate 2, and the operation is simpler.
