Description

Technical Field

[0001] This utility model relates to the field of electromagnetic compatibility testing technology, specifically to a continuous control fixture for a foot-operated triggering device in electromagnetic compatibility testing. Background Technology

[0002] Both radiated emission and radiated immunity tests in electromagnetic compatibility (EMC) testing must be conducted in an anechoic chamber. During the test, personnel are not allowed to enter the anechoic chamber. For some foot-operated trigger devices that cannot work continuously, since they are triggered only once per foot pedal, they cannot work continuously and thus cannot meet the test requirements. The test requirements are that the device must be in the triggered state and work continuously without interruption; the foot switch must be placed on a non-metallic support 10cm high; at the same time, the test environment should be kept quiet and in a non-vibration state.

[0003] Therefore, this application is submitted. Utility Model Content

[0004] The purpose of this invention is to provide a continuous control fixture for a foot-operated trigger device in electromagnetic compatibility testing. By setting a movable pressing block above the platform and adjusting the position of the pressing block by moving rods and connecting rods, the pressing block is kept pressing against the switch of the foot-operated trigger device, thus continuously keeping it in the triggered state for testing, thereby solving the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A continuous control fixture for a foot-operated trigger device in electromagnetic compatibility testing includes a placement platform, a vertical rod, and a pressing block for pressing down the foot-operated trigger device. The vertical rod is detachably connected to the interior of the placement platform. The end of the pressing block is provided with a moving rod and a connecting rod for height adjustment. The end of the connecting rod away from the vertical rod is located inside the moving rod to adjust the distance between the pressing block and the vertical rod.

[0007] Furthermore, the placement platform is made of non-metallic material and is equipped with a threaded sleeve, the bottom of the vertical rod is provided with an external thread that matches the threaded sleeve, and the bottom end of the vertical rod is located inside the threaded sleeve.

[0008] Furthermore, the end of the connecting rod is provided with a clamp located on the outer periphery of the vertical rod. The clamp has an open end and connecting ears are respectively provided at both ends of the open end. Bolts pass through the connecting ears.

[0009] Furthermore, a sliding groove is formed inside the movable rod, and the end of the connecting rod away from the clamp is located in the sliding groove.

[0010] Furthermore, the outer wall of the movable rod is symmetrically provided with protrusions and limiting blocks, and the diameter of the sliding groove away from the pressing block is smaller than the outer diameter of the limiting block.

[0011] Furthermore, a screw hole one is provided at the top of the connecting rod, a screw hole two is provided at the top of the moving rod, and a wing screw one is provided at the overlapping point of the screw hole one and the screw hole two.

[0012] Furthermore, a wing-shaped screw is provided at the center of the pressing block.

[0013] Furthermore, the length of the second wing screw is greater than the thickness of the press block.

[0014] Furthermore, a collar and a reinforcing rod are provided below the clamp. The collar is located on the outer periphery of the vertical rod, and the reinforcing rod connects the collar and the connecting rod.

[0015] Furthermore, a clearance groove is provided at the bottom of the sliding groove, and one end of the reinforcing rod moves within the clearance groove.

[0016] The beneficial effects of this utility model are:

[0017] This invention features a vertically movable connecting rod and a horizontally movable moving rod, secured by bolts or a wing screw. These components ensure the pressing plate tightly presses against the foot-operated switch. Simultaneously, the wing screw at the center, extending through the rod and moving vertically along with the connecting rod, applies double pressure to the foot-operated trigger switch. This enhances the continuous triggering of the switch, ensuring uninterrupted operation. Furthermore, it eliminates the need for manual operation of the trigger switch, maintaining a quiet testing environment and improving the accuracy of test results.

[0018] By setting a collar and a reinforcing rod below the clamp that move synchronously with the clamp, and fixing one end of the reinforcing rod to the connecting rod, the positional stability of the connecting rod is increased, and the continuous triggering performance is improved.

[0026] Example 1

[0027] Embodiment 1 of this utility model is a continuous control fixture for a foot-operated trigger device in electromagnetic compatibility testing, including a placement platform 1, a vertical rod 2, and a pressing block 5 for pressing down the foot-operated trigger device. The vertical rod 2 is detachably connected to the interior of the placement platform 1. The end of the pressing block 5 is provided with a moving rod 4 and a connecting rod 3 for height adjustment. The end of the connecting rod 3 away from the vertical rod 2 is located inside the moving rod 4 to adjust the distance between the pressing block 5 and the vertical rod 2.

[0028] Reference Figures 1 to 3This application mainly involves setting a vertical rod 2 above the placement platform 1, a connecting rod 3 perpendicular to the vertical rod 2, and a moving block. The connecting rod 3 moves up and down around the outer periphery of the vertical rod 2 to adjust the pressing block 5 and its height, so that the height of the pressing block 5 is slightly lower than the switch of the foot-operated trigger device, thereby achieving tight pressing of the switch and realizing continuous triggering of the foot-operated trigger device, thus ensuring continuous and uninterrupted operation; there is no need for manual continuous stepping on the trigger switch, keeping the test environment quiet and improving the accuracy of the test results.

[0029] To facilitate the assembly and disassembly of the tooling, the placement platform 1 is made of non-metallic material and is equipped with a threaded sleeve 10. The bottom of the vertical rod 2 has an external thread that matches the threaded sleeve 10, and the bottom end of the vertical rod 2 is located inside the threaded sleeve 10. A threaded sleeve 10 is installed inside the placement platform 1, with a section of external thread on the bottom of the vertical rod 2 connecting to the threaded sleeve 10, enabling convenient assembly and disassembly of this tooling for easy storage. The placement platform 1 is also made of non-metallic material and has a height of 10cm to meet the placement requirements of the foot switch. The specific materials and specifications of the threaded sleeve 10 and the vertical rod 2 are determined according to actual conditions and will not be elaborated here.

[0030] Furthermore, restrictions are placed on the vertical movement of the connecting rod 3 within the vertical rod 2 and on the adjustment of the distance between the pressing block 5 and the vertical rod 2. The end of the connecting rod 3 is provided with a clamp 30 located on the outer periphery of the vertical rod 2. The clamp 30 has an open end, with connecting ears 31 at both ends of the open end, through which bolts 32 pass. A sliding groove 40 is formed inside the movable rod 4, and the end of the connecting rod 3 away from the clamp 30 is located within the sliding groove 40. Symmetrical protrusions 33 and limiting blocks 34 are provided on the outer wall of the movable rod 4, and the diameter of the sliding groove 40 away from the pressing block 5 is smaller than the outer diameter of the limiting block 34.

[0031] On the one hand, by setting a clamp 30 and a connecting ear 31 at one end of the connecting rod 3, the vertical rod 2 passes through the center of the clamp 30, and the clamp 30 is locked or loosened by the bolts 32 passing through the two connecting ears 31, thereby fixing or releasing the position of the connecting rod 3 and the moving rod 4, which makes it easy to change the height of the connecting rod 3 and the moving rod 4.

[0032] On the other hand, the sliding groove 40 inside the moving rod 4 is used to assemble the connecting rod 3, so that the moving rod 4 moves left and right around the outer periphery of the connecting rod 3, driving the pressing block 5 to move. With the height and left and right position adjusted, the pressing block 5 is tightly pressed against the switch of the foot-operated trigger device for continuous triggering. Furthermore, symmetrical protrusions 33 and limiting blocks 34 are provided on the outer wall of the connecting rod 3 to ensure that the moving rod 4 does not deviate during movement and to prevent the connecting rod 3 from dislodging from the interior of the moving rod 4.

[0033] To fix the position of the pressing block 5 after left and right movement, a screw hole 35 is provided on the top of the connecting rod 3, and a screw hole 41 is provided on the top of the moving rod 4. A wing screw 6 is provided at the overlapping point of the screw holes 35 and 41. Several screw holes 35 and 41 are provided, and a wing screw 6 is provided at the overlapping point. The number of wing screws 6 can be set according to the actual situation, which will not be described in detail here.

[0034] Furthermore, a wing-shaped screw 7 is provided at the center of the pressing block 5. The length of the wing-shaped screw 7 is greater than the thickness of the pressing block 5. By adjusting the length of the wing-shaped screw 7 passing through the pressing block 5, and by the vertical movement of the connecting rod 3, dual pressure is applied to the foot-operated trigger switch, thereby improving the continuous triggering of the foot-operated trigger switch by this fixture.

[0035] Example 2

[0036] This embodiment 2 is implemented based on embodiment 1. A collar 8 and a reinforcing rod 9 are provided below the clamp 30. The collar 8 is located on the outer periphery of the vertical rod 2, and the reinforcing rod 9 connects the collar 8 and the connecting rod 3. To ensure the stability of the connecting rod 3 and the moving rod 4 after their positions are determined, a collar 8 is provided that fits over the outside of the vertical rod 2, and the collar 8 and the connecting rod 3 are fixed together by the reinforcing rod 9, thereby ensuring the stability of the connecting rod 3 and improving continuous triggering performance.

[0037] Meanwhile, a clearance groove 42 is provided at the bottom of the sliding groove 40, and one end of the reinforcing rod 9 moves within the clearance groove 42. The clearance groove 42 is mainly designed to allow the reinforcing rod 9 to move, so that the moving block can move left and right around the outer periphery of the connecting rod 3 without affecting the connecting function of the reinforcing rod 9. The connection position of the reinforcing rod 9 below the connecting rod 3 can be set according to the actual situation.

[0038] The working principle of this utility model is as follows: In use, the switch of the foot-operated trigger device is placed above the placement platform 1. The bolt 32 is loosened, and the connecting rod 3, the moving rod 4, and the pressing plate are moved slightly below the switch position by the up-and-down movement of the clamp 30 on the vertical rod 2. The bolt 32 is then tightened to fix this height. At the same time, the moving rod 4 is moved around the outer periphery of the connecting rod 3 so that the edge of the pressing plate is above the switch position. The wing screw 6 is then used to lock and fix this position. The length of the wing screw 7 passing through the pressing block 5 is then adjusted, and the vertical movement of the connecting rod 3 applies double pressure to the switch of the foot-operated trigger device, improving the continuous triggering of the foot-operated trigger device switch by this fixture, thereby ensuring continuous and uninterrupted operation. There is no need for manual continuous stepping on the trigger switch, keeping the test environment quiet and improving the accuracy of the test results.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
