[0027] Refer to the attached Figure 1 -Attached Figure 8 An embodiment of the present application provides an antenna, including: an antenna body 1, a positioning pin 2 and a connecting frame 3, the antenna body 1 includes a first antenna 11 and a second antenna 12, the connecting frame 3 is arranged at an end where the first antenna 11 and the second antenna 12 are close to each other, one end of the connecting frame 3 is detachably connected to one end of the first antenna 11, and the other end of the connecting frame 3 is connected to one end of the second antenna 12 through the positioning pin 2.

[0028] In this embodiment, the large-sized antenna body 1 is separately arranged as the first antenna 11 and the second antenna 12, and the first antenna 11 and the second antenna 12 are combined through the connecting frame 3. The first antenna 11 and the second antenna 12 are connected at one end close to each other through the connecting frame 3, and are locked by the positioning pin 2 to achieve stable assembly of the antenna. When storing and carrying, it is only necessary to release the detachable connection part to achieve quick storage and carrying of the antenna.

[0029] The connecting frame 3 and the first antenna 11 can be connected by a detachable connection method such as threaded connection, clamping connection, etc., or by a locking pin as shown in the figure. The connecting frame 3 is provided with a socket matching the positioning pin 2, and the second antenna 12 is provided with the same hole. After the positioning pin 2 is inserted and penetrates the socket and enters the hole on the second antenna 12, the connection between the connecting frame 3 and the second antenna 12 is realized. The structure of the connecting frame 3 can be as shown in the attached figure. Figure 3As shown, a U-shaped plate is used, and the first antenna 11 and the second antenna 12 are inserted into the interior of the U-shaped plate from the opening of the U-shaped plate. The first antenna 11 and the second antenna 12 are aligned under the restriction of the connecting frame 3.

[0030] The structure of the positioning pin is as shown in the attached Figure 4 , Attachment Figure 5 As shown, the workpiece hole is used as the positioning reference, and the part that participates in limiting the freedom of the object is used. When the body is connected by multiple parts, and each part needs to maintain a precise position during processing and assembly, a positioning pin should be used for positioning, and cylindrical pins or conical pins are usually used. Furthermore, a pull rope hole can be set on the positioning pin 2 to prevent the positioning pin 2 from falling.

[0031] In one embodiment, as shown in the attached Figure 2 As shown, the antenna also includes an antenna vibrator 4, which is detachably connected to the antenna body 1. The antenna vibrator is a component on the antenna, which has the function of guiding and amplifying electromagnetic waves, so that the electromagnetic signal received by the antenna is stronger. The antenna vibrator is made of metal with good conductivity. Some vibrators are rod-shaped, and some have more complex structures. Generally, many vibrators are arranged in parallel on the antenna, as shown in the attached figure. Figure 1 The detachable connection of the antenna vibrator 4 can further enhance the detachability of the antenna, making it easier to disassemble and store. The antenna vibrator 4 can be detachably connected to the antenna body 1 by plugging or bolting, or by the method provided in the embodiment of the present application, specifically:

[0032] The antenna vibrator 4 is detachably connected to the antenna body 1 through the connecting assembly 5, and the connecting assembly 5 includes a first support plate 52, a second support plate 53 and a butterfly buckle 51. The first support plate 52 is arranged on the antenna body 1, and the second support plate 53 is connected to the antenna vibrator 4. The first support plate 52 and the second support plate 53 are provided with matching threaded holes, and the screw of the butterfly buckle 51 matches the threaded holes and passes through the first support plate 52 and the second support plate 53. As shown in the above embodiment, the butterfly buckle 51 is also called a butterfly card, which is a tool for locking and anchoring a tie rod. Compared with the traditional threaded tie rod, it not only replaces the function of the nut and the gasket, but also changes the operation mode of the traditional template tie rod.

[0033] In one embodiment, as shown in the attached Figure 2 As shown, in order to enable the first support plate 52 and the second support plate 53 to be fastened together, a positioning hole is provided on the first support plate 52, and a positioning column matched with the positioning hole is provided on the second support plate 53. When the first support plate 52 and the second support plate 53 are matched, the positioning column is inserted into the positioning hole. Figure 6The figure shows the structure of the second support plate 53, wherein the left side is a hole for the screw of the butterfly buckle 51, and the right side is a protruding positioning column. The positioning column cooperates with the positioning hole to achieve rapid buckling of the support plate, and then the butterfly buckle 51 is used to tighten the support plate to achieve rapid installation of the antenna vibrator 4. Further, in order to improve the quality of disassembly and assembly, the first support plate 52 and the second support plate 53 are both L-shaped plates, as shown in the attached figure. Figure 7 As shown, the second support plate 53 is an L-shaped plate. After the L-shaped first support plate 52 and the second support plate 53 are snap-fitted, they can fit more closely to achieve a more stable connection.

[0034] In one embodiment, since the antenna may be used in a harsh environment, special attention should be paid to rust and corrosion of these disassembled parts. Therefore, the butterfly buckle 51 can be made of stainless steel to improve performance and service life. According to the definition in GB / T20878-2007, stainless steel is steel with stainless and corrosion resistance as main characteristics, and a chromium content of at least 10.5% and a carbon content of no more than 1.2%. Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, and water or has stainless properties is called stainless steel, and steel that is resistant to corrosion by chemical corrosive media (chemical erosion such as acids, alkalis, and salts) is called acid-resistant steel.

[0035] In one embodiment, since the antenna vibrator 4 occupies a large part in the use of the antenna, the antenna vibrator 4 is made of aluminum alloy in consideration of cost and portability. Aluminum alloy is an alloy with aluminum as the base and a certain amount of other alloying elements added. It is one of the light metal materials. In addition to the general characteristics of aluminum, it has some specific characteristics of alloys due to the different types and quantities of added alloying elements. The density of aluminum alloy is 2.63-2.85 g / cm3, with high strength, specific strength close to high alloy steel, specific stiffness exceeding steel, good casting performance and plastic processing performance, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as a structural material. In addition, the antenna vibrator 4 can be designed to be retractable for easy storage, and a part of the antenna vibrator 4 can be designed to be connected to the ball head of the antenna body 1, so as to be retracted along the direction of the antenna body 1 after rotation.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
