Description

Technical Field

[0001] This utility model belongs to the field of passive transmitting antenna technology, specifically relating to a three-degree-of-freedom adjustment device for a passive transmitting antenna. Background Technology

[0002] Passive transmitting antennas can transmit signals in the GPS, GLONASS, and BeiDou frequency bands, featuring high gain, good low elevation gain, wide-angle circular polarization, and stable phase center. Suitable for multiple systems, they can be widely used in signal relay-related equipment and facilities.

[0003] Passive transmitting antennas require debugging during use and installation. Existing installation methods primarily rely on stainless steel pipes, clamps, and other fixed mounting devices to secure the antenna to a specific location. This fixed connection prevents the antenna's position and orientation from being freely adjusted according to signal transmission requirements. This hinders debugging and makes it difficult to find the optimal signal location for the passive transmitting antenna. Utility Model Content

[0004] The purpose of this invention is to provide a three-degree-of-freedom adjustment device for a passive transmitting antenna, so as to enable free adjustment of the position and direction of the passive transmitting antenna according to signal transmission requirements.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a three-degree-of-freedom adjustment device for a passive transmitting antenna, including a vertical displacement adjustment component, a yaw rotation adjustment component, and a pitch rotation adjustment component; one end of the vertical displacement adjustment component is connected to an external base, and the other end of the vertical displacement adjustment component is connected to the yaw rotation adjustment component, which is used to adjust and secure the height of the passive transmitting antenna; the yaw rotation adjustment component is used to adjust and secure the yaw rotation angle of the passive transmitting antenna; one end of the pitch rotation adjustment component is connected to the yaw rotation adjustment component, and the other end is connected to the passive transmitting antenna, which is used to adjust and secure the pitch angle of the passive transmitting antenna.

[0006] Compared with the prior art, the significant advantages of this utility model are:

[0007] 1. A three-degree-of-freedom adjustment device for a passive transmitting antenna, disclosed in this utility model, includes a vertical displacement adjustment rod, a yaw rotation table, a pitch adjustment rod, and other mechanisms and devices, enabling adjustment of three degrees of freedom: vertical displacement, yaw rotation, and pitch rotation. Furthermore, locking bolts and locking rods are employed to achieve both adjustment and locking functions, maintaining the mechanism at a specific position and angle, facilitating the operation of the passive transmitting antenna.

[0008] 2. In terms of vertical adjustment, three parts are used: a vertical fixed rod, a vertical moving rod, and a displacement locking hand-tightened Torx bolt. It has the function of vertical displacement adjustment. When adjusted to the required position, the vertical moving rod can be locked and fixed by the displacement locking hand-tightened Torx bolt.

[0009] 3. In terms of yaw adjustment, a yaw rotary table is constructed, consisting of upper and lower parts, which can rotate around the vertical moving rod and has the function of yaw direction rotation adjustment. When adjusted to the required angle, the upper yaw rotary table can be locked and fixed by hand-tightening the yaw locking bolts.

[0010] 4. For pitch adjustment, a pitch adjustment lever is used, rotating around the pitch lock lever as an axis. It provides rotational adjustment in the pitch direction. When the desired angle is reached, the pitch adjustment lever can be locked in place using the pitch lock lever. (See attached diagram for details.)

[0024] The purpose of this invention is to facilitate the effective adjustment of the antenna position and orientation during the debugging and testing of a passive transmitting antenna, and to provide a three-degree-of-freedom adjustment device for a passive transmitting antenna.

[0025] The beneficial effect of this utility model is that it can realize the three-degree-of-freedom adjustment of the passive transmitting antenna, including the three degrees of freedom of vertical displacement adjustment, yaw rotation adjustment, and pitch rotation adjustment.

[0026] To achieve the above objectives, the following technical solution is adopted.

[0027] like Figure 1 As shown, this utility model discloses a three-degree-of-freedom adjustment device for a passive transmitting antenna, comprising a vertical displacement adjustment component, a yaw rotation adjustment component, a pitch rotation adjustment component, and a passive transmitting antenna.

[0028] The vertical displacement adjustment assembly includes a vertical fixed rod 101, a vertical moving rod 102, and a displacement locking hand-tightened Torx bolt 103. The vertical moving rod 102 is integrally formed by a vertical moving rod body 1021 and a vertical moving rod plug 1022.

[0029] The vertical fixing rod 101 can be fixedly connected to the external base by bolts and clamps (the type of base is determined by the usage scenario and environment, and is not strictly specified here). The vertical fixing rod 101 has 10 holes spaced 30mm apart, which facilitates multi-level position adjustment.

[0030] The vertical moving rod 102 is connected to the vertical fixed rod 101 via a displacement locking hand-tightened Torx bolt 103 (detachable connection). The vertical moving rod 102 has three holes spaced 30mm apart, facilitating adjustment of its position by engaging with the vertical fixed rod 101. Position adjustment along the vertical direction is achieved through the engagement of different holes.

[0031] The yaw rotation adjustment assembly includes an upper yaw rotation table 201, a lower yaw rotation table 202, a yaw lock hand-tightening plum bolt 203, a flange fixing bolt 204, and a flange fixing nut 205.

[0032] like Figure 2 As shown, the vertical moving rod body 1021 passes through the upper yaw rotary table 201 and is connected to the vertical fixed rod 101. In addition, the vertical moving rod plug 1022 provides a limiting effect with the upper yaw rotary table 201, which can keep the upper yaw rotary table 201 hanging on the vertical moving rod 102 and prevent it from falling off.

[0033] like Figure 1 As shown, the lower yaw rotary table 202 and the upper yaw rotary table 201 are connected by four sets of flange fixing bolts 204 and flange fixing nuts 205 (detachable connection).

[0034] During use, the upper yaw rotary table 201 and the lower yaw rotary table 202 rotate synchronously. After adjusting to the specified angle as needed, the yaw lock can be locked by tightening the yaw lock hand-tightened plumb bob 203 to prevent further yaw rotation.

[0035] like Figure 5 As shown, the lower yaw rotary table 202 is provided with: a light hole 2021, a locking plane 2022, and a hole thread 2023.

[0036] The pitch rotation adjustment assembly includes a pitch adjustment rod 301 and a pitch locking rod 302. Wherein, as... Figure 4 As shown, the pitch lock lever 302 is divided into four sections: handle 3021, first optical axis 3022, second optical axis 3023, and shaft thread 3024.

[0037] like Figure 3 As shown, firstly, the pitch lock lever 302 passes through the aperture 2021 of the lower yaw rotary table 202, so that the first optical axis 3022 of the pitch lock lever 302 contacts and engages with the aperture 2021 of the lower yaw rotary table 202 (allowing it to rotate relative to the axis); nextly, the pitch lock lever 302 passes through the pitch adjustment lever 301, so that the second optical axis 3023 of the pitch lock lever 302 engages with the aperture of the pitch adjustment lever 301; finally, through a threaded connection, the shaft thread 3024 of the pitch lock lever 302 is connected to the hole thread 2023 of the lower yaw rotary table 202.

[0038] like Figure 3 As shown, the pitch adjustment rod 301 can rotate around the pitch lock rod 302 to generate pitch rotation. After adjusting to the specified angle as needed, by tightening the pitch lock rod 302, the stepped surface between the first optical axis 3022 and the second optical axis 3023 of the pitch lock rod 302 presses against one end face of the pitch adjustment rod 301, thereby pressing the other end face of the pitch adjustment rod 301 against the locking plane 2022 of the lower yaw rotary table 202. The locking state is achieved by the friction between the surfaces, preventing further pitch rotation.

[0039] The passive transmitting antenna 401 is a finished product from the shelf. The adjustment device of this utility model is used to match the passive transmitting antenna 401, and will not be described in detail.

[0040] The pitch adjustment rod 301 is connected to the passive transmitting antenna 401 via a thread (detachable connection).

[0041] Usage process:

[0042] The first step is to fix the vertical fixing rod 101 to a base using additional bolts or clamps (the type of base depends on the usage scenario and environment, and is not strictly specified here).

[0043] The second step is position adjustment. There are 10 holes with a spacing of 30mm on the vertical fixed rod 101. According to the vertical position adjustment requirements, align the holes of the vertical moving rod 102 with the holes of the vertical fixed rod 101. The displacement locking hand-tightened Torx bolt 103 passes through the vertical moving rod 102 and connects to the vertical fixed rod 101 to fix the position of the two.

[0044] The third step is yaw adjustment. Loosen the yaw lock hand-tightened Torx bolt 203, and simultaneously rotate the upper yaw rotary table 201 and the lower yaw rotary table 202. After adjusting to the specified angle as needed, tighten the yaw lock hand-tightened Torx bolt 203 to achieve the locked state.

[0045] Fourth step, pitch adjustment: loosen the pitch lock lever 302, rotate the pitch adjustment lever 301 around the pitch lock lever 302 to pitch as needed, and then tighten the pitch lock lever 302 to achieve the locked state.
