Description

Technical Field

[0001] This utility model relates to the field of backpack weather technology, specifically an adjustable and fixed antenna structure for a backpack radio. Background Technology

[0002] A backpack radio is a portable radio that is designed to be carried by a single person for mobile communication. The entire device (main unit, battery, antenna) is integrated into a backpack system, allowing the operator to quickly establish communication while moving or in a fixed location. Since backpack radios need to work while moving or in different terrains, the backpack antenna has a rotation adjustment function in actual use.

[0003] For example, Chinese Publication No. CN221783428U discloses a broadband backpack antenna, including a rod structure with a connecting structure at the bottom. The connecting structure includes a fixed base located below the rod structure; a screw fixedly connected to the lower side of the fixed base; and a damping shaft passing through the fixed base and rotatably connected to it. This broadband backpack antenna, through the use of the connecting structure, uses center-fed arms one and two. Slits are made at appropriate positions on the two arms of the dipole, dividing it into four segments. The center position is the antenna feed point, serving as a high-frequency radiator. The enameled wire between the connecting slits at the far end of the feed point acts as a filter to block high frequencies. The near and far ends of the feed point act as low-frequency radiators, cleverly dividing the entire frequency band into high and low bands, effectively realizing the impedance bandwidth across the entire frequency band and improving the antenna's performance.

[0004] In the above solution, the antenna angle is adjusted by a damping shaft, relying on the friction of the damping shaft to maintain the antenna angle. However, in practical use, due to the large vibration amplitude of the backpack radio during carrying, the damping shaft is prone to misalignment, causing changes in the antenna angle. Furthermore, after a period of use, the frictional resistance of the damping shaft easily decreases, making it impossible to maintain the antenna angle in subsequent use. Therefore, this paper proposes an adjustable antenna fixing structure for backpack radios. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable antenna fixing structure for a backpack radio in order to solve the problems in the above-mentioned solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable fixing structure for a backpack radio antenna, comprising a backpack antenna consisting of a stud, a connecting seat, a connector, an antenna body, and a damping shaft. The connecting seat is fixed to the top of the stud, and the connector is fixed to the bottom of the antenna body. The connector is distributed inside the connecting seat and is rotatably connected to the connecting seat via the damping shaft. An auxiliary fixing component is provided between the outer side of the antenna body and the outer side of the connecting seat. The auxiliary fixing component is used to reinforce and support the antenna body in its tilted state.

[0007] The antenna body includes a support unit and a locking unit;

[0008] The support unit is used to provide support for the tilted antenna body;

[0009] The locking unit is used to fix and reinforce the support unit and the antenna body.

[0010] As a further embodiment of this utility model: the support unit includes a sleeve, a T-shaped column, an I-shaped column, and a support arm;

[0011] The sleeve is slidably fitted onto the outside of the antenna body, and the T-shaped post is fixed to one side of the outer wall of the sleeve;

[0012] The I-shaped column is fixed to one side of the outer wall of the connecting seat, and the support arm is rotatably sleeved on the outside of the T-shaped column and the I-shaped column;

[0013] When the antenna body rotates, the sleeve slides along the outer wall of the antenna body, and the support arm rotates synchronously. After rotation, there is an angle between the support arm and the antenna body, which is used to provide support for the antenna body.

[0014] As a further embodiment of this utility model: when the I-shaped columns are distributed below the damping shaft and the antenna body is vertically distributed, the centers of the T-shaped columns, I-shaped columns, and damping shaft are located on the same vertical axis.

[0015] As a further improvement of this utility model: the locking unit includes a locking bolt;

[0016] The T-shaped column has a screw hole formed on its inner side, and the screw hole penetrates the sleeve and is connected to the inner side of the sleeve.

[0017] The locking bolt is threaded into the screw hole and fits tightly against the outer wall of the antenna body to lock the relative position of the sleeve and the antenna body.

[0018] As a further improvement of this utility model: the inner diameter of the sleeve is matched with the outer diameter of the antenna body, and there is frictional resistance between the sleeve and the outer diameter of the antenna body.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up auxiliary fixing components to support and fix the antenna body, compared with the structure that only relies on the rotational resistance of the damping shaft to maintain the angle of the antenna body, it can effectively avoid the antenna body from deflecting due to vibration during the carrying process, and further improve the stability of the antenna body in use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 In this embodiment of the present invention, an adjustable fixing structure for a backpack radio antenna includes a backpack antenna 1 consisting of a stud 101, a connecting seat 102, a connector 103, an antenna body 104, and a damping shaft 105. The connecting seat 102 is fixed to the top of the stud 101, and the connector 103 is fixed to the bottom of the antenna body 104. The connector 103 is distributed on the inner side of the connecting seat 102 and is rotatably connected to the connecting seat 102 through the damping shaft 105. An auxiliary fixing component 2 is provided between the outer side of the antenna body 104 and the outer side of the connecting seat 102. The auxiliary fixing component 2 is used to reinforce and support the antenna body 104 in an inclined state.

[0028] The antenna body 104 includes a support unit and a locking unit. The support unit is used to provide support for the tilted antenna body 104, and the locking unit is used to fix and reinforce the support unit and the antenna body 104.

[0029] The support unit includes a sleeve 201, a T-shaped column 202, an I-shaped column 203, and a support arm 204;

[0030] The sleeve 201 is slidably sleeved on the outside of the antenna body 104, and the T-shaped post 202 is fixed to one side of the outer wall of the sleeve 201.

[0031] The I-shaped column 203 is fixed to one side of the outer wall of the connecting seat 102, and the support arm 204 is rotatably sleeved on the outside of the T-shaped column 202 and the I-shaped column 203;

[0032] When the antenna body 104 rotates, the sleeve 201 slides along the outer wall of the antenna body 104, and the support arm 204 rotates synchronously. After rotation, there is an angle between the support arm 204 and the antenna body 104, which is used to provide support for the antenna body 104.

[0033] The I-shaped columns 203 are distributed below the damping shaft 105. When the antenna body 104 is vertically distributed, the centers of the T-shaped columns 202, the I-shaped columns 203, and the damping shaft 105 are located on the same vertical axis.

[0034] The locking unit includes a locking bolt 205;

[0035] The T-shaped column 202 has a screw hole formed on its inner side, and the screw hole passes through the sleeve 201 and is connected to the inner side of the sleeve 201.

[0036] The locking bolt 205 is threaded into the screw hole and fits tightly against the outer wall of the antenna body 104 to lock the relative position of the sleeve 201 and the antenna body 104.

[0037] In this embodiment: When in use, the backpack antenna 1 can be connected to the connection port on the backpack radio via the stud 101. The antenna body 104 can be rotated and adjusted around the damping shaft 105 to reduce communication blind spots and improve the antenna's signal reception effect.

[0038] During this process, the support arm 204 rotates around the I-shaped column 203, and the sleeve 201 slides relative to the antenna body 104 while rotating with the antenna body 104 (it should be noted that at this time the locking bolt 205 is in a loose state, that is, the locking bolt 205 is not in contact with the antenna body 104). When the antenna body 104 is tilted at a certain angle, there is a certain angle between the support arm 204 and the antenna body 104.

[0039] Afterwards, tighten the locking bolt 205 to make it fit tightly against the outer wall of the antenna body 104. At this time, the sleeve 201 and the antenna body 104 cannot be positioned relative to each other, thereby fixing the angle of the antenna body 104. Compared with the structure that only relies on the rotational resistance of the damping shaft 105 to maintain the angle of the antenna body 104, the auxiliary fixing component 2 is used to support and fix the antenna body 104. During the process of carrying it forward, it can effectively avoid the antenna body 104 from deflecting due to vibration, and further improve the stability of the antenna body 104 in use.

[0040] Please refer to this carefully. Figures 1-4 The inner diameter of the sleeve 201 matches the outer diameter of the antenna body 104, and there is frictional resistance between the sleeve 201 and the outer diameter of the antenna body 104.

[0041] In this embodiment: through the frictional resistance between the sleeve 201 and the antenna body 104, even when the locking bolt 205 is not tightened, the auxiliary fixing component 2 can also provide a certain auxiliary support force for the antenna body 104. Combined with the rotational resistance of the damping shaft 105, the angle of the antenna body 104 can be kept stable. Moreover, the auxiliary fixing component 2 can effectively reduce the burden on the damping shaft 105 and effectively improve the service life of the damping shaft 105.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
