[0021] The present utility model will be further described below with reference to the accompanying drawings:

[0022] As Figures 1 - 3 shown, the manual lodging device for small flat antenna lodging test described in the present utility model includes a horizontal bottom plate 2, a vertical support plate 7, a rotating arm 4, an antenna mounting plate 1, an operation knob 11, a first transmission rod 13, a second transmission rod 14, and a connecting rod 15. The lower ends of two mutually parallel support plates 7 are respectively mounted on the bottom plate 2. The support plate 7 is provided with guiding grooves (refer to the vertical guiding groove 5 and the arc-shaped guiding groove 3 in the following content). The first ends of the two ends of the two rotating arms 4 are respectively connected to the same end of the antenna mounting plate 1. A connecting rod 15 in the horizontal direction is connected between the second ends of the two ends of the two rotating arms 4. The rotating arm 4 is provided with guiding columns. The guiding columns of the two rotating arms (refer to the first guiding column 8 and the second guiding column 6 in the following content) are respectively placed in the guiding grooves of the two support plates 7. The operation knob 11 is mounted on one of the support plates 7 and is connected to one end of the first transmission rod 13. The other end of the first transmission rod 13 is rotatably connected to one end of the second transmission rod 14 through a rotating shaft. The other end of the second transmission rod 14 is rotatably connected to one end of the connecting rod 15 in a sleeved manner. During the forward and reverse rotation of the operation knob 11, the antenna mounting plate 1 can be driven to change between the horizontal and vertical directions through the first transmission rod 13, the second transmission rod 14, the connecting rod 15, and the two rotating arms 4.

[0023] As Figures 1 - 3 shown, the present utility model also discloses the following various more optimized specific structures:

[0024] To better achieve the function of driving the antenna mounting plate 1 to rotate by operating the operating knob 11, the guiding groove includes a vertical guiding groove 5 and an arc guiding groove 3. The lower end of the arc guiding groove 3 with a central angle of 90° of the circle it is on coincides with the vertical midpoint position of the vertical guiding groove 5. The upper end of the arc guiding groove 3 is vertically flush with the upper end of the vertical guiding groove 5. The center of the circle where the arc guiding groove 3 is located coincides with the upper end of the vertical guiding groove 5. The operating knob 11 is located below the arc guiding groove 3. The sum of the lengths of the first transmission rod 13 and the second transmission rod 14 is not less than the distance between the operating knob 11 and the upper end of the arc guiding groove 3. The guiding columns on each rotating arm 4 include a first guiding column 8 and a second guiding column 6. The first guiding column 8 is arranged at the second end of the rotating arm 4, and the second guiding column 6 is arranged in the middle section of the rotating arm 4 and is located in the corresponding vertical guiding groove 5. The distance between the first guiding column 8 and the second guiding column 6 is half of the length of the vertical guiding groove 5.

[0025] For ease of assembly and operation, the two rotating arms 4 are located between the two support plates 7 and are respectively close to the inner sides of the two support plates 7. The first transmission rod 13 and the second transmission rod 14 are located on the inner sides of the corresponding support plates 7, and the operating knob 11 is located on the outer side of the corresponding support plate 7.

[0026] For ease of assembly, the operating knob 11 is connected to one end of a horizontal connecting shaft (not visible in the figure but easy to understand) through a connecting screw 10. The connecting shaft passes through the corresponding through hole of the corresponding support plate 7, and the other end of the connecting shaft is connected to one end of the first transmission rod 13.

[0027] To reduce the friction between the connecting shaft and the support plate 7 and increase the rotational damping coefficient of the operating knob 11 to facilitate controlling the rotation state of the antenna mounting plate 1, a bearing (not visible in the figure but easy to understand) is installed between the connecting shaft and the hole wall of the corresponding through hole of the corresponding support plate 7. There is a counterbore on the outer wall of the support plate 7 where the operating knob 11 is installed, and the connecting shaft passes through the center position at the bottom of the counterbore, and a shrink fit 9 is installed in the counterbore. The inner end of the operating knob 11 is placed inside the shrink fit 9.

[0028] To improve the stability of the antenna mounting plate 1 when it is in the horizontal position, the antenna mounting plate 1 is located above the two support plates 7 when it is in the horizontal position.

[0029] To enable the antenna mounting plate 1 to have a buffering effect of gradually stopping when it rotates to the horizontal position, rubber buffer pads 12 are installed on the upper parts of the support plates 7. When the antenna mounting plate 1 is in the horizontal position, it contacts the rubber buffer pads 12 on the upper parts of the two support plates 7 respectively.

[0030] As Figures 1 - 6 shown, in application, first install a small flat antenna (not shown in the figure) on the antenna mounting plate 1. Before the test starts, the antenna mounting plate 1 is in the horizontal position and contacts the rubber buffer pads 12, asFigure 3 as shown; then start to rotate the operation knob 11 by hand, and rotate it in the clockwise direction as shown in Figures 3 - 6 . The first transmission rod 13 is driven to rotate clockwise, and the connecting rod 15 is pushed upward through the second transmission rod 14. During this process, the second transmission rod 14 rotates adaptively, and the connecting rod 15 drives the two rotating arms 4 to move upward simultaneously. Both the first guide post 8 and the second guide post 6 slide upward in the vertical guide groove 5. During this process, the antenna mounting plate 1 remains horizontal and moves upward; when the second guide post 6 moves to the upper end of the vertical guide groove 5, the second guide post 6 cannot continue to move upward, as shown in Figure 4 . At this time, the first guide post 8, the rotating arm 4, and the antenna mounting plate 1 cannot move upward, and the antenna mounting plate 1 remains horizontal and is in the highest position; continue to rotate the operation knob 11 clockwise. Since the first guide post 8 is located at the lower end of the arc-shaped guide groove 3 at this time, under the push of the first transmission rod 13 and the second transmission rod 14, the first guide post 8 starts to slide in the arc-shaped guide groove 3. The second guide post 6 cannot move but can rotate adaptively. The second transmission rod 14 always rotates adaptively, and the rotating arm 4 starts to rotate, driving the antenna mounting plate 1 to rotate. When it rotates 45°, as shown in Figure 5 . At this time, the first guide post 8 is located in the middle of the arc-shaped guide groove 3; continue to rotate the operation knob 11 clockwise, and the antenna mounting plate 1 continues to rotate. When the first guide post 8 reaches the upper end of the arc-shaped guide groove 3, the first guide post 8 cannot rotate anymore. At this time, the first guide post 8 and the second guide post 6 are flush vertically, and the antenna mounting plate 1 is in the vertical direction, as shown in Figure 6 . The maximum 90° rotation of the antenna mounting plate 1 is achieved; at any time during the rotation of the antenna mounting plate 1, the rotation operation knob 11 can be stopped as needed to make the antenna mounting plate 1 at the tilt angle required for testing, and the test of the small flat antenna receiving signal can be carried out. After the test is completed, continue to rotate the operation knob 11; the process of converting the antenna mounting plate 1 from the vertical direction to the horizontal direction is similar to the above, but only need to rotate the operation knob 11 counterclockwise in the reverse direction, driving the antenna mounting plate 1 to rotate in the reverse direction until it is finally horizontal and in contact with the rubber buffer pad 12 to complete the lodging operation, as shown in Figure 3 . During this process, the rotation operation knob 11 can also be stopped at any time to make the antenna mounting plate 1 at the tilt angle required for testing, and the test of the small flat antenna receiving signal can be carried out.

[0031] The above embodiments are only the preferred embodiments of the present invention, and do not limit the technical solutions of the present invention. As long as the technical solutions that can be achieved on the basis of the above embodiments without creative labor shall be regarded as falling within the scope of the protection of the present invention patent.
