[0036] 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.

[0037] Example 1, please refer to Figures 1 to 5 The present invention provides an embodiment of an amplifier board debugging and positioning platform for electromagnetic interference resistance, comprising a workbench 100 disposed on a debugging machine, the debugging machine being provided with debugging circuitry and corresponding electrical components, the debugging machine being used for debugging an amplifier board for electromagnetic interference resistance, and a positioning structure 200 disposed on the workbench 100; wherein, a groove 101 is provided on the workbench 100.

[0038] The positioning structure 200 includes a fixed block A202, a fixed block B203, a threaded rod 204, a rotating handle 206, a movable block 205, and an L-shaped block 207. The fixed block A202 is fixed at one end of the groove 101; the fixed block B203 is fixed at the other end of the groove 101; the threaded rod 204 is disposed in the groove 101; one end of the threaded rod 204 is rotatably connected to the fixed block A202 via a rotating shaft, and the other end of the threaded rod 204 passes through a hole in the fixed block B203; the rotating handle 206 is fixed at the other end of the threaded rod 204; two movable blocks 205 are respectively threaded onto the two threaded sections of the threaded rod 204; the movable blocks 205 are slidably fitted with the groove 101; the transverse sections of the two L-shaped blocks 207 are respectively fixed onto the two movable blocks 205.

[0039] The operator rotates the handle 206 to drive the forward and reverse thread screws 204 to rotate. The two movable blocks 205 move relative to or away from each other along the groove 101 to adjust the distance between the two L-shaped blocks 207. The distance between the two L-shaped blocks 207 is adjusted to a suitable position for the amplifier board. The board is clamped between the longitudinal sections of the two L-shaped blocks 207, and the transverse sections of the two L-shaped blocks 207 support the board. Then, the amplifier board is debugged using a debugging machine.

[0040] This utility model, by setting a fixed block A202, a fixed block B203, a positive and negative threaded screw 204, a movable block 205, a rotating handle 206, and an L-shaped block 207, has the advantage of adjusting the distance between the longitudinal sections of the two L-shaped blocks 207 according to the size of the amplifier board, and is suitable for placing boards of different sizes. It solves the problem that the positioning device set on the platform has a fixed position and cannot accurately position boards of different lengths.

[0041] Example 2, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 One embodiment of this utility model provides: an amplifier board debugging and positioning platform for electromagnetic interference resistance. Two tracks 201 are symmetrically fixed on the workbench 100 with the groove 101 as the axis. Two sliders 208 are symmetrically fixed on the bottom side of the transverse section of the L-shaped block 207. The sliders 208 slide in cooperation with the grooves of the tracks 201. When the L-shaped block 207 moves, the sliders 208 move along the grooves of the tracks 201. The sliders 208 are T-shaped and are adapted to the grooves of the tracks 201. The T-shaped sliders 208 slide stably in the grooves of the tracks 201.

[0042] This utility model, by setting a track 201 and a slider 208, has the advantage of assisting the movement of the L-shaped block 207 by having the slider 208 slide within the groove of the track 201, thus maintaining the stable movement of the L-shaped block 207.

[0043] Example 3, please refer to Figure 2 , Figure 5 and Figure 7 One embodiment of this utility model is an amplifier board debugging and positioning platform for electromagnetic interference resistance. A stop block 209 is inserted into the hole of the longitudinal section of the L-shaped block 207. A connecting plate 210 is fixed to the outer end of the stop block 209. A spring 211 is provided between the connecting plate 210 and the longitudinal section of the L-shaped block 207. The two ends of the spring 211 are fixedly connected to the connecting plate 210 and the longitudinal section of the L-shaped block 207, respectively. The elastic coefficient of the spring 211 can be selected and used by the technical personnel in this field according to the actual situation.

[0044] The amplifier board is placed between the longitudinal sections of two L-shaped blocks 207. The inner end of the abutment block 209 abuts against the board. The elastic force provided by the stretched spring 211 makes the inner end of the abutment block 209 abut against the board.

[0045] The inner top side of the abutment block 209 is set as an inclined surface 2091. When a single board is placed between the longitudinal sections of the two L-shaped blocks 207, the side end of the single board is pushed along the inclined surface 2091 to push the abutment block 209 out, which facilitates the placement of the single board.

[0046] Limiting blocks 212 are fixed on both sides of the abutment block 209. The limiting blocks 212 cooperate with the longitudinal section of the L-shaped block 207 to limit the position of the inner end of the abutment block 209, so that the inclined surface 2091 can correspond to the single board when it is placed.

[0047] This utility model, by setting up a stop block 209, a connecting plate 210, a spring 211, and a limiting block 212, has the advantage of further abutting the single board after it is placed, thereby strengthening the fixation of the single board.

[0048] Working principle: The distance between the longitudinal sections of the two L-shaped blocks 207 is adjusted according to the size of the amplifier board. The operator rotates the handle 206 to drive the positive and negative thread screws 204 to rotate. The two movable blocks 205 move relative to or away from each other along the groove 101. The slider 208 slides in the groove of the track 201 to adjust the distance between the two L-shaped blocks 207 to a suitable position for the amplifier board. The board is clamped between the longitudinal sections of the two L-shaped blocks 207. When the board is placed between the longitudinal sections of the two L-shaped blocks 207, the side end of the board pushes along the inclined surface 2091 to push out the abutment block 209. The spring 211 is further stretched until the transverse section of the L-shaped block 207 supports the board. The inner end of the abutment block 209 abuts against the board. The elastic force provided by the stretched spring 211 makes the inner end of the abutment block 209 abut against the board. Then, the amplifier board is adjusted by the debugging machine.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
