Description

Technical Field

[0001] The utility model relates to an antenna back clip and an antenna with the back clip, and is applicable to the technical field of antenna manufacturing. Background Art

[0002] The antenna back clamp is a component used on the antenna, which is mainly used to connect the antenna reflective surface with the feed rod, bracket and other structures. The existing antenna back clamp is usually composed of an I-shaped base plate and a pair of vertical plates arranged vertically on the base plate. For example, the back clamp involved in the patent with publication number CN214625383U is connected to the convex surface of the antenna reflective surface through an I-shaped mounting plate, and then connected to the antenna bracket through a connecting bracket, while the feed rod is connected to the I-shaped mounting plate by bolts. In the prior art, the connection structure between the feed rod and the back clamp is usually to open corresponding bolt holes on the back clamp base plate and the end of the feed rod, and then assemble and fix them by inserting connecting bolts. However, since there is usually a certain gap between the bolt hole and the bolt, there is still a movable space between the feed rod and the back clamp after the assembly is completed (such as the attached Figure 5 As shown in the figure, and because the antenna needs to be installed outdoors, when encountering strong winds, the feed rod is easily disturbed by the wind and displaced, resulting in a change in the feed position, which reduces the stability of the antenna's receiving and transmitting signals and has an adverse effect on the antenna's wind resistance. Utility Model Content

[0003] In order to solve the defects of the above-mentioned prior art, the utility model provides an antenna back clip and an antenna having the back clip.

[0004] The technical solution adopted by the present invention is: on the one hand, the present invention discloses an antenna back clip, including an assembly base plate installed on the convex surface of the antenna reflective surface, a pair of assembly clamps vertically connected to the assembly base plate and used to assemble the antenna bracket, the assembly base plate includes a base plate body, at least two first connection holes opened on the back of the base plate body and used to connect the antenna feed rod, and at least one pair of limiting bulges protruding from the back of the base plate body and used to limit the position of the antenna feed rod. The at least two first connection holes are arranged along the length direction of the base plate body, and each pair of limiting bulges are arranged along the width direction of the base plate body, and each pair of limiting bulges are respectively located on both sides of the at least two first connection holes, and the spacing between each pair of limiting bulges is the same as the width of the antenna feed rod. The feed rod and the antenna back clamp are bolted together through the first connecting hole, and the feed rod can be fixed to the base plate body while being clamped between the pair of limiting convex bumps through at least one pair of limiting convex bumps. The displacement space of the feed rod is limited by the limiting convex bumps to ensure the tightness and stability of the connection between the feed rod and the antenna back clamp, thereby improving the antenna's wind resistance and the stability of the receiving and transmitting signals, and avoiding the adverse effects on the antenna performance caused by the fitting gap between the first connecting hole and the connecting bolt.

[0005] Furthermore, at least two pairs of limiting convex bumps are provided, and at least two pairs of limiting convex bumps are arranged along the length direction of the base plate body. By using multiple pairs of limiting convex bumps, the assembly stability between the feed rod and the antenna back clamp is further improved. At the same time, during assembly, the end of the feed rod can be clamped between at least two pairs of limiting convex bumps and then the bolts can be connected, which reduces the difficulty of assembly.

[0006] Furthermore, each limiting bulge is configured to be hemispherical. Due to the structural feature of the hemispherical shape being small at the top and large at the bottom, the limiting bulge and the feed rod can be increasingly pressed against each other as the bolts are tightened, ensuring the tightness and stability of the connection between the limiting bulge and the back clamp after the bolts are tightened.

[0007] Furthermore, the mounting base includes at least four mounting portions, located at the four corners of the base body. Each mounting portion is provided with a second connection hole for connecting to the antenna reflector. The at least four mounting portions located at the corners of the base body connect the mounting base to the convex surface of the antenna reflector, ensuring not only a secure connection between the back clip and the antenna reflector but also a stable assembly.

[0008] Furthermore, the mounting base also includes a connecting portion connected to each mounting portion and the base body. The connecting portion is inclined from one end connected to the base body to the other end, from the back side of the base body to the front side. The inclined connecting portion allows the base body to be suspended above the convex surface of the antenna reflector when the mounting portion is connected to the convex surface of the antenna reflector. This prevents the curvature of the convex surface of the antenna reflector from interfering with the connection between the back clip and the reflector, thereby ensuring the tightness and stability of the connection between the back clip and the antenna reflector.

[0009] Furthermore, reinforcing ribs are provided on the back of the connecting part, and the reinforcing ribs are U-shaped. By providing the U-shaped reinforcing ribs on the connecting part, the structural stability between the base plate body and the mounting part is improved, thereby improving the connection stability and firmness between the antenna bracket and the feed rod and the antenna reflecting surface, and preventing the antenna from shaking during use due to harsh external environments such as windy and rainy weather.

[0010] Furthermore, a pair of assembly clamps are respectively connected to the base body and arranged along the width direction of the base body, and the pair of assembly clamps extend in the direction of the back of the base body, so as to clamp the upper end of the antenna bracket between the pair of assembly clamps to realize the connection and assembly between the back clamp and the antenna bracket.

[0011] On the other hand, the utility model also discloses an antenna, including an antenna reflecting surface, a back clip fixed on the convex surface of the antenna reflecting surface, an antenna feed rod connected to the back clip at one end, and a bracket connected to the back clip at one end and fixedly mounted on the ground at the other end, wherein the back clip adopts the above-mentioned antenna back clip.

[0012] Due to the application of the above technical solution, the present invention has the following advantages over the prior art:

[0013] The antenna back clip and the antenna having the back clip in the present invention have a simple structure and are easy to assemble. By arranging at least a pair of limiting convex bumps on the base plate body of the antenna back clip, the feed rod can be fixed to the base plate body by bolts and can be clamped between the pair of limiting convex bumps. The displacement space of the feed rod is limited by the limiting convex bumps, ensuring the tightness and stability of the connection between the feed rod and the antenna back clip, thereby improving the wind resistance of the antenna and the stability of the receiving and transmitting signals, and avoiding the adverse effects on the antenna performance caused by the fitting gap between the first connecting hole and the connecting bolt.

Furthermore, the technical features of the different embodiments of this utility model described below may be combined unless they conflict with each other.

[0024] Reference Attachment Figure 1-5 On the one hand, this embodiment discloses an antenna back clip, including a back clip mounted on an antenna reflector surface (such as the attached Figure 1 The assembly base plate 1 on the convex surface of the structure shown by the number b) is vertically connected to the assembly base plate 1 and is used to assemble the antenna bracket (such as the attached Figure 1The assembly base plate 1 includes a base plate body 11, a base plate body 11 and a base plate 12 for connecting the antenna feed rod (such as the attached Figure 1 The structure shown in the figure is as shown in the figure by the number a), and at least two first connection holes 12 of the bottom plate body 11, and at least one pair of limiting bumps 13 protruding from the back of the bottom plate body 11 and used to limit the position of the antenna feed rod. The at least two first connection holes 12 are arranged along the length direction of the bottom plate body 11, and each pair of limiting bumps 13 are arranged along the width direction of the bottom plate body 11, and each pair of limiting bumps 13 are respectively located on both sides of the at least two first connection holes 12, and the spacing between each pair of limiting bumps 13 is the same as the width of the antenna feed rod. The bolt connection between the feed rod and the antenna back clamp is achieved through the first connection holes 12, and through the at least one pair of limiting bumps 13, the feed rod can be fixed to the bottom plate body 11 by bolts and can be clamped between the pair of limiting bumps 13 (as shown in the attached figure). Figure 4 As shown), the displacement space of the feed rod is limited by the limiting convex bump 13, ensuring the tightness and stability of the connection between the feed rod and the antenna back clamp, thereby improving the wind resistance of the antenna and the stability of the receiving and transmitting signals, and avoiding the adverse effects on the antenna performance caused by the fitting gap between the first connecting hole 12 and the connecting bolt.

[0025] In a more preferred embodiment, at least two pairs of limiting bulges 13 are provided, and at least two pairs of limiting bulges 13 are arranged along the length direction of the base plate body 11. By using multiple pairs of limiting bulges 13, the assembly stability between the feed rod and the antenna back clamp is further improved. At the same time, during assembly, the end of the feed rod can be clamped between at least two pairs of limiting bulges 13 and then the bolts can be connected, which reduces the difficulty of assembly.

[0026] In a more preferred embodiment, each limiting bump 13 is configured to be hemispherical. Due to the structural feature of the hemispherical shape being small at the top and large at the bottom, the limiting bump 13 and the feed rod can be increasingly pressed against each other as the bolts are tightened, ensuring the tightness and stability of the connection between the limiting bump 13 and the back clamp after the bolts are tightened.

[0027] In a more preferred embodiment, the mounting base 1 further includes at least four mounting portions 14, located at the four corners of the base body 11. Each mounting portion 14 is provided with a second connection hole 141 for connecting to the antenna reflector.

[0028] In a more preferred embodiment, the mounting base 1 further includes a connecting portion 15 connected between each mounting portion 14 and the base body 11. The connecting portion 15 is inclined from one end connected to the base body 11 to the other end, from the back side of the base body 11 to the front side. The inclined connection portion 15 allows the base body 11 to be suspended above the convex surface of the antenna reflector when the mounting portion 14 is connected to the convex surface of the antenna reflector. This prevents the curvature of the convex surface of the antenna reflector from interfering with the connection between the back clip and the reflector, thereby ensuring the tightness and stability of the connection between the back clip and the antenna reflector.

[0029] In a more preferred embodiment, a reinforcing rib 151 is provided on the back of the connecting portion 15, and the reinforcing rib 151 is U-shaped. By providing the reinforcing rib 151 on the connecting portion 15, the structural stability between the base plate body 11 and the mounting portion 14 is improved, thereby improving the connection stability and firmness between the antenna bracket and the feed rod and the antenna reflecting surface, and preventing the antenna from shaking during use due to harsh external environments such as windy and rainy weather.

[0030] In a more preferred embodiment, a pair of assembly clamps 2 are respectively connected to the base plate body 11 and arranged along the width direction of the base plate body 11, and the pair of assembly clamps 2 extend in the direction of the back of the base plate body 11, so as to facilitate clamping the upper end of the antenna bracket between the pair of assembly clamps 2 to achieve the connection and assembly between the back clamp and the antenna bracket.

[0031] On the other hand, this embodiment also discloses an antenna, including an antenna reflector (such as the attached Figure 1 The structure shown in the middle mark b), the back clip fixed on the convex surface of the antenna reflector (as shown in the attached Figure 1 The structure shown by the label d), one end of which is connected to the antenna feed rod on the back clamp (as shown in the attached Figure 1 The structure shown by number a), one end of which is connected to the back clip and the other end is fixed to the ground (such as the attached Figure 1 The back clip adopts the above-mentioned antenna back clip.

[0032] Due to the application of the above technical solution, the present invention has the following advantages over the prior art:

[0033] The antenna back clip and the antenna having the back clip in the present invention have a simple structure and are easy to assemble. By arranging at least a pair of limiting convex bumps on the base plate body of the antenna back clip, the feed rod can be fixed to the base plate body by bolts and can be clamped between the pair of limiting convex bumps. The displacement space of the feed rod is limited by the limiting convex bumps, ensuring the tightness and stability of the connection between the feed rod and the antenna back clip, thereby improving the wind resistance of the antenna and the stability of the receiving and transmitting signals, and avoiding the adverse effects on the antenna performance caused by the fitting gap between the first connecting hole and the connecting bolt.
