[0036] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0037] The utility model discloses a hanging point simulator, such as Figure 1 and Figure 2 As shown, it includes a shell, which includes a front panel 30 and a rear panel, and the front panel 30 and the rear panel are connected by two side panels 20, a top panel and a bottom panel 40; a plurality of parallel limit strips 21 are evenly arranged on the inner side of the side panel 20 from front to back, and the limit strips 21 are in an up-down direction; the top ends of the plurality of limit strips 21 are connected to an interface board 60, and a pin row is provided on the interface board 60 and between two adjacent limit strips 21; when the board 70 is connected to the pin row, a locking block 80 is arranged between the limit strip 21 and the board 70, and the front and rear end surfaces of the locking block 80 respectively abut against the board 70 and the limit strip 21.

[0038] The utility model designs limiting strips 21 on the two side panels 20, so that a board 70 installation space is formed between adjacent limiting strips 21. After the board 70 is installed, the locking block 80 is used to firmly fix the board 70 between the two limiting strips 21, thereby improving the stability of the board 70.

[0039] In addition, when the width of the hanging point simulator is large, a partition board 50 can be installed between the two side panels 20, and limiting strips 21 are also provided on both sides of the partition board 50, so that a placement space for multiple boards 70 can be formed between the partition board 50 and the two side panels 20.

[0040] In the embodiment of the present invention, the cross section of the limit strip 21 is square, and two adjacent limit strips 21 have planes opposite to each other, and the board 70 is locked by the two planes. The interface board 60 is the bottom board to which the board 70 is plugged, and the electrical components are attached to it. The bottom board is connected to the aviation plug above the interface board 60 through the connecting wire to provide an analog signal for the aviation interface to be tested.

[0041] Regarding the position of the locking block 80, different sizes are selected according to the distance between the limit strip 21 and the board 70. The locking block 80 can be set on one side of the board 70 or on both sides of the board 70. The fixing block 81 is fixedly mounted on the limit strip 21 or the board 70.

[0042] Specifically, Figure 3 He Ru Figure 4 As shown, the locking block 80 includes a screw 84, and the screw 84 has the same direction as the limit strip 21; the screw 84 is penetrated with a first movable block 82, a fixed block 81, a second movable block 83 and a nut 85 from top to bottom in sequence; the fixed block 81 and the first movable block 82 are both provided with through holes for the screw 84 to pass through, and the second movable block 83 is provided with a threaded hole threadedly connected to the screw 84; the relative surfaces between the fixed block 81 and the first movable block 82 are both inclined surfaces.

[0043] The fixed block 81 is fixed on the limit strip 21 or the board 70. The fixed block 81 has a through hole, the diameter of which is slightly larger than the diameter of the screw 84. In this embodiment, its cross section is an isosceles trapezoid. The first movable block 82 also has a through hole, the diameter of which is also slightly larger than the diameter of the screw, and its cross section is a right-angled trapezoid. The second movable block 81 has a threaded hole, the internal thread of which matches the external thread of the screw 84, and its cross section is also a right-angled trapezoid. When the screw 84 is screwed, the screw 84 interacts with the nut 85 and the second movable block 83, so that the fixed block 81 generates an extrusion force with the first movable block 82 and the second movable block 83. The second movable block 83 moves along the inclined surface under the action of the extrusion force and the inclined surface of the fixed block 81, so that the thickness of the locking block 80 increases, fills the board 70 and the limit strip 21, and fixes the board 70.

[0044] In one embodiment, the bottom panel 40 is connected to the side panel 20 by connecting screws 41, and both the bottom panel 40 and the side panel 20 have threaded holes; Figure 5As shown, the connecting screw 41 includes a straight rod section 412 located in the threaded hole of the bottom panel 40 and a threaded section 411 located in the threaded hole of the side panel 20, and the diameter of the threaded section 411 is greater than the diameter of the straight rod section 412. Since the plugging and unplugging of the board 70 requires the disassembly of the bottom panel 40, if ordinary screws and connecting structures are used after the bottom panel 40 is disassembled, the screws are easy to fall off and lose. When the structure of the utility model is used to disassemble the bottom panel 40, after the threaded section 411 is screwed out of the side panel 20, if the connecting screw is not screwed, due to the existence of the threaded section 411 and the threaded hole of the bottom panel, the straight rod section will be stuck in the threaded hole of the bottom panel 40, thereby preventing the connecting screw from falling off. Furthermore, the internal thread of the threaded hole on the bottom panel 40 may not cover the entire threaded hole, and its internal thread may be only two or three turns, and the part thereof can be directly opened as a through hole, which reduces the difficulty of processing.

[0045] The hanging point simulator of the utility model further includes a handle 10, which can be convenient for the user to carry, and when the hanging point simulator is used for testing, the handle 10 can also be used as a support for the shell to adjust the screen angle on the front panel 30. For example, when the user is standing to operate, the hanging point simulator is placed on the desktop, and the handle 10 can be used as a support for the shell to tilt the screen toward the user's face, so as to better observe the test data.

[0046] Specifically, Figure 1 and Figure 8 As shown, the handle 10 is U-shaped, and its two ends are rotatably connected to the two side panels 20 respectively. Figure 6 As shown, the handle 10 is connected to the side panel 20 via a connecting rod, which passes through a through hole of the side panel 20 and is fixedly connected to the handle 10 ; wherein a rubber ring 11 is sleeved on the connecting rod, and the rubber ring 11 is located between the handle 10 and the side panel 20 .

[0047] In addition, the connection portion between the outer side of the side panel 20 and the handle has a limiting groove 22, and the vertical cross section of the limiting groove 22 is arc-shaped. Figure 7 As shown, a limiting block 12 is provided on the end surface of the handle 10 facing the side panel 20 at a position corresponding to the limiting groove 22; when the handle 10 rotates relative to the side panel 20, the limiting block 12 moves in the limiting groove 22. The limiting groove 22 and the limiting block 12 cooperate with each other to ensure that the handle 10 rotates according to a predetermined trajectory.
