Description

Technical Field

[0001] This utility model belongs to the field of machinery and relates to a rotating shaft, specifically to an antenna rotating shaft suitable for handheld radios and a handheld radio. Background Technology

[0002] When handheld radios are used in areas without base station signals, such as disaster relief and outdoor exploration, an external antenna is usually required. For convenient signal reception, the antenna needs to be rotatable, necessitating the addition of an antenna hinge between the antenna and the handheld radio. Therefore, the reliability of the antenna hinge becomes one of the key factors in the reliability of the handheld radio.

[0003] like Figure 1 As shown, for aesthetic appeal and ease of use, the antenna hinge 1 and antenna 2 are designed on the side of the handheld radio body 3. The antenna hinge 1 must ensure that the antenna 2 can rotate within a certain angle and can be stably stopped at any position. Furthermore, the antenna is a precision electronic component and cannot be exposed to rainwater. To meet the requirements of use in harsh environments, it also needs to have reliable waterproofing during frequent rotation.

[0004] Because antenna 2 needs to be rotated frequently to change angles, the sealing rings and stop structures in the rotating parts experience wear. Considering the entire life cycle, it needs to be easy to disassemble and maintain. However, the existing antenna shaft uses glue or welding to seal some disassembly points, requiring the replacement of the entire shaft for maintenance. This is inconvenient for replacing individual parts and results in high operating costs. Furthermore, if the sealing rings in the rotating parts are damaged and leak water, water can seep into the antenna and handheld radio, causing damage to the entire device. Utility Model Content

[0005] Purpose of the utility model: The purpose of this utility model is to provide an antenna hinge and a handheld radio suitable for handheld radios, which can improve the inconvenience of maintenance and waterproof performance, and make the product maintenance cost lower.

[0006] Technical Solution: This utility model provides an antenna swivel shaft suitable for handheld radios, comprising a fixed part and a rotating part disposed above the fixed part; a first disc spring is placed inside the fixed part, separating the fixed part and the rotating part; a second disc spring is placed inside the rotating part, with a locking nut disposed above the second disc spring; a rotating shaft is vertically disposed in the center of the fixed part, and a first through hole is opened at one end of the rotating part for the rotating shaft to pass through; after the rotating shaft of the fixed part passes through the first through hole, the locking nut is connected to the external thread at the top of the rotating shaft, thereby connecting the fixed part and the rotating part into a whole, and the rotating part is rotatably connected to the fixed part; an antenna-end RF adapter is installed at the other end of the rotating part, one end of the antenna-end RF adapter extends into the rotating part for docking with the RF connector of the fixed part, and the other end of the antenna-end RF adapter is fixed to the rotating part by a tail locking cap; the end of the antenna-end RF adapter extends out of the tail locking cap for connecting with the antenna; a top cover plate is placed above the rotating part, and the top cover plate is locked to the rotating part by locking screws.

[0007] Furthermore, a toothed slip ring combination sealing ring is used between the fixed part and the rotating part to achieve dynamic sealing.

[0008] Furthermore, a limiting boss is provided on the bottom surface of the rotating part, and a limiting groove is provided on the outer periphery of the rotating shaft of the fixed part. The limiting boss and the limiting groove cooperate with each other. When the rotating part is pulled, the limiting boss of the rotating part moves in the limiting groove of the fixed part.

[0009] Furthermore, the limiting groove is designed as a non-closed ring, with a rubber post at each end of the limiting groove. The non-closed ring design can prevent the rotating part from hitting the handheld rooftop body during rotation, and the rubber posts are provided to prevent wear on the rotating part and the fixed part during rotation.

[0010] Furthermore, a first end face sealing ring is provided between the rotating part and the tail locking cap, and a second end face sealing ring is provided between the rotating part and the antenna end RF adapter. By setting the first end face sealing ring and the second end face sealing ring, the sealing performance of the end of the rotating part can be enhanced.

[0011] Furthermore, a channel connected to the first through hole is opened inside the rotating part along its length direction. The radio frequency line at the tail of the fixed part passes through this channel, and a radio frequency connector is installed at the end of the radio frequency line. The radio frequency connector is connected to the radio frequency adapter at the antenna end in the channel, which can connect the radio frequency signals inside and outside the handheld radio body.

[0012] Furthermore, an anti-rotation structure is provided on the inner wall of the other end of the rotating part, and the antenna-end RF adapter is installed in the anti-rotation structure to realize the positioning of the antenna-end RF adapter and prevent sliding problems during the antenna assembly and disassembly process.

[0013] Furthermore, a radial sealing ring is provided between the upper cover plate and the rotating part to achieve a seal between the upper cover plate and the rotating part.

[0014] Furthermore, the locking nut has mounting and disassembly grooves on both sides to facilitate disassembly and maintenance using special tools.

[0015] Based on the same inventive concept, this utility model provides a handheld radio, including an antenna, a handheld radio body, and the aforementioned antenna shaft suitable for a handheld radio. A groove is formed on the side of the handheld radio body, and one end of the antenna shaft extends into the interior of the handheld radio body from the side wall of the groove. The fixing part of the antenna shaft is fixedly connected to the lower half of the handheld radio body, and an antenna is installed at the end of the antenna-end RF adapter in the antenna shaft. A third end face sealing ring is provided between the antenna and the tail locking cap of the antenna shaft, achieving a static seal between the antenna and the antenna shaft. A sealing ring is provided on the bottom surface of the fixing part of the antenna shaft, achieving a static seal between the handheld radio body and the antenna shaft.

[0016] Beneficial effects: Compared with the prior art, the significant technical effects of this utility model are as follows: (1) The tail locking cap, the top cover plate and the locking nut in this solution are all threaded locking, which is easy to disassemble and assemble, and can replace the internal worn parts, thus improving the problem of inconvenient replacement of single parts and high maintenance costs; (2) The antenna can be stably stopped at any position by two sets of disc springs. When the disc springs are severely worn and the antenna shakes, the locking force can be increased by adjusting the locking nut, without having to replace the entire antenna shaft immediately. It is easy to operate and has low operating costs; (3) The handheld radio and the fixed part, the antenna and the rotating part are designed with separate static seals. The easily worn dynamic seal ring is located between the fixed part and the rotating part. Even if the dynamic seal ring is damaged during the whole life cycle and water leakage occurs, it will only occur inside the antenna shaft and will not endanger the inside of the handheld radio and the antenna. It improves the problem of water leakage damaging the whole machine. Attached Figure Description

[0026] The technical solution of this utility model will now be described in detail with reference to specific embodiments and accompanying drawings.

[0027] Example 1

[0028] like Figure 2-9 As shown, this utility model discloses an antenna hinge suitable for handheld radios, specifically involving the following components: a fixing part 11, a rotating part 12, a first disc spring 131, a second disc spring 132, a locking nut 14, a tail locking cap 15, an antenna-end RF adapter 16, a top cover plate 17, a locking screw 18, a toothed slip ring type combined sealing ring 19, a screw fixing hole 111, a sealing ring 112, a limiting groove 113, a rubber post 114, an RF connector 115, a first end face sealing ring 121, a second end face sealing ring 122, an anti-rotation structure 123, a limiting boss 124, a disassembly groove 141, a third end face sealing ring 151, a symmetrical parallel surface 152, and an axial sealing ring 171. The specific connection method is as follows:

[0029] like Figure 2 and Figure 3As shown, the antenna shaft of this utility model for handheld radios mainly includes two parts: a fixed part 11 and a rotating part 12, with the rotating part 12 positioned above the fixed part 11. A first disc spring 131 is placed inside the fixed part 11, separating the fixed part 11 and the rotating part 12. A second disc spring 132 is placed inside the rotating part 12, with a locking nut 14 positioned above the second disc spring 132. The fixed part 11 and the rotating part 12 are locked together by the locking nut 14, specifically as follows: a rotating shaft is vertically positioned in the center of the fixed part 11, and a first through hole is opened at one end of the rotating part 12 for the rotating shaft to pass through. After the rotating shaft of the fixed part 11 passes through the first through hole, the locking nut 14 is connected to the external thread at the top of the rotating shaft, thereby connecting the fixed part 11 and the rotating part 12 into a whole, and the rotating part 12 is rotatably connected to the fixed part 11. An antenna-end RF adapter 16 is mounted on the other end of the rotating part 12. One end of the antenna-end RF adapter 16 extends into the rotating part 12 to mate with the RF connector 115 of the fixing part 11, and the other end of the antenna-end RF adapter 16 is fixed to the rotating part 12 by a tail locking cap 15. The end of the antenna-end RF adapter 16 extends out of the tail locking cap 15 for connection with the antenna. A top cover plate 17 is placed on top of the rotating part 12, and the top cover plate 17 is locked to the rotating part 12 by locking screws 18.

[0030] The structural components are assembled and secured using a locking nut 14, a tail locking cap 15, and a locking screw 18. This threaded locking method facilitates disassembly and assembly, and allows for the replacement of internal worn parts. It improves upon the problems of inconvenient replacement of individual parts and high maintenance costs.

[0031] In this design, a first disc spring 131 and a second disc spring 132 are used for locking and limiting, while separating the fixed part 11 and the rotating part 12. This ensures that only the disc springs will wear throughout their lifespan, protecting both the fixed part 11 and the rotating part 12. When the disc springs wear down, causing the antenna 2 to wobble, the locking nut 14 can be tightened to increase the friction between the disc springs and improve the limiting effect. Even when wear is severe, only the disc springs need to be replaced. Operation and maintenance are convenient and cost-effective.

[0032] The rotating part 12 has a channel connected to the first through hole along its length. The radio frequency line at the tail of the fixing part 11 passes through this channel. The end of the radio frequency line is equipped with a radio frequency connector 115. The radio frequency connector 115 is connected to the antenna end radio frequency adapter 16 in the channel.

[0033] like Figure 3 As shown, a dynamic seal is achieved between the fixed part 11 and the rotating part 12 using a toothed slip ring combination seal 19 for rotating shaft.

[0034] like Figure 4 and Figure 5As shown, the outer periphery of the fixing part 11 is provided with three screw fixing holes 111 for locking with the handheld radio body 3 by screws. The fixing part 11 and the handheld radio body 3 are sealed by a sealing ring 112.

[0035] like Figure 2 and Figure 6 As shown, a first end-face sealing ring 121 is provided between the rotating part 12 and the tail locking cap 15, and a second end-face sealing ring 122 is provided between the rotating part 12 and the antenna-end RF adapter 16. The diameter of the first end-face sealing ring 121 is larger than the diameter of the second end-face sealing ring 122. An anti-rotation structure 123 is provided on the inner wall of the other end of the rotating part 12. The antenna-end RF adapter 16 is installed in the anti-rotation structure 123 to achieve positioning of the antenna-end RF adapter 16. Because the anti-rotation structure 123 is used between the rotating part 12 and the antenna-end RF adapter 16, slippage during antenna assembly and disassembly is prevented, ensuring antenna stability and reliable end-face sealing.

[0036] like Figure 2 and Figure 4-6 As shown, a limiting boss 124 is provided on the bottom surface of the rotating part 12, and a limiting groove 113 is provided on the outer periphery of the rotating shaft of the fixed part 11. The limiting boss 124 cooperates with the limiting groove 113. When the rotating part 12 is pulled, the limiting boss 124 of the rotating part 12 moves in the limiting groove 113 of the fixed part 11. The limiting groove 113 is designed as a non-closed ring, and a rubber post 114 is provided at each end of the limiting groove 113. When the limiting boss 124 of the rotating part 12 rotates in the limiting groove 113 of the fixed part 11, it reciprocates in contact with the rubber posts 114 at the beginning and end, which will not cause wear to the rotating part 12 and the fixed part 11, ensuring the stability and reliability of the structure.

[0037] like Figure 7 As shown, for special installation environments, the locking nut 14 has disassembly and assembly grooves 141 on both sides of the support to facilitate disassembly and maintenance using special tools. Figure 8 As shown, a third end-face sealing ring 151 is provided on the outer side of the tail locking cap 15, and the outer side of the third end-face sealing ring 151 contacts the antenna 2. A pair of symmetrical parallel surfaces 152 are designed on both sides of the tail locking cap 15 to facilitate fastening and ensure the stability and reliability of the end-face seal at this location. Figure 9 As shown, a radial sealing ring 171 is provided between the upper cover plate 17 and the rotating part 12.

[0038] Example 2

[0039] This utility model discloses a handheld radio, including an antenna 2, a handheld radio body 3, and an antenna shaft 1 suitable for handheld radios as described in Embodiment 1. A groove is formed on the side of the handheld radio body 3. One end of the antenna shaft 1 extends into the interior of the handheld radio body 3 from the side wall of the groove. The fixing part 11 of the antenna shaft 1 is fixedly connected to the lower half of the handheld radio body 3. The antenna 2 is installed at the end of the antenna-end RF adapter 16 in the antenna shaft 1.

[0040] A third end face sealing ring 151 is provided between the antenna 2 and the tail locking cap 15 of the antenna shaft 1, which achieves static sealing between the antenna 2 and the antenna shaft 1. A sealing ring 112 is provided on the bottom surface of the fixing part 11 of the antenna shaft 1, which achieves static sealing between the handheld radio body 3 and the antenna shaft 1.

[0041] Because the handheld radio body 3, antenna 2 and antenna shaft 1 are designed with separate static seals, the easily worn dynamic seal ring (i.e. toothed slip ring type combined seal ring 19) is located between the fixed part 11 and the rotating part 12. Even if the dynamic seal ring is damaged and water leakage occurs during the entire life cycle, it will only occur inside the antenna shaft 1 and will not endanger the internal circuit board of the handheld radio body 3 and the antenna 2, thus improving the problem of water leakage damaging the whole machine.
