When using the power switch, if non-staff use it, the cover presser 41 will be pressed down in a conventional way. When the cover presser 41 moves downward and contacts the rotating plate 44, it will drive the inner side of the rotating plate 44 to swing downward. The outer side of the rotating plate 44 swings upwards to contact the middle position of the alarm 42, and the torsion spring 45 is twisted, and the alarm 42 then sends out an alarm. In addition, after the outer side of the rotating plate 44 is blocked by the middle position of the alarm 42, the rotating plate 44 will be stopped. Turn, and the rotating plate 44 will limit the position of the cover presser 41, which can prevent the cover presser 41 from continuing to move downwards to trigger the start switch 3, which can prevent non-staff from arbitrarily triggering the start switch 3, and can improve the safety of the power switch When the staff uses it, the staff first moves the push plate 51 inwardly to drive the wedge-shaped push rod 52 to move inwardly, the push spring 53 is compressed, and the wedge-shaped push rod 52 will squeeze the outer position of the rotating plate 44, so that the rotating plate The outer side of 44 swings downward, and the inner side of the rotating plate 44 swings upward, and the torsion spring 45 is twisted.

After the wedge-shaped push rod 52 unclamps the rotating plate 44, under the effect of the torsion spring 45, it drives the rotating plate 44 to rotate and reset, but under the effect of the deceleration spring 47 and the deceleration block 46, The rotation speed of the rotating plate 44 can be decelerated, so that the rotating plate 44 will reset slowly, preventing the alarm 42 from being accidentally triggered during the reset process of the rotating plate 44, and avoiding invalid alarm prompts.

Example 2

On the basis of Embodiment 1, as shown in Figure 2, Figure 7 and Figure 8, a reset mechanism 6 is also included, including a sliding block 61, a sliding connecting rod 62 and a pressure spring 63, and the front and rear sides of the mounting frame 2 are The left and right symmetrical slides are connected with a sliding block 61, and the sliding block 61 is rotatably connected with a sliding connecting rod 62. A compression spring 63 is connected.

When the covering presser 41 moves downward, the sliding connecting rod 62 will drive the sliding block 61 to move inward, so that the compression spring 63 is compressed. At this time, the compression spring 63 can buffer and decelerate the covering presser 41. Moreover, it can make the cover presser 41 descend more smoothly. When the cover presser 41 is released, under the action of the pressure spring 63, the sliding block 61 will be driven to move to the outside to reset, and the cover presser will be driven by the sliding connecting rod 62 at the same time. 41 automatic upward movement reset.

As shown in Figure 2, Figure 9 and Figure 10, it also includes a misleading mechanism 7, the misleading mechanism 7 includes a pressing frame 71, a limiting block 74 and a limiting assembly, and the front and rear sides of the lower part of the cover presser 41 are bolted with limiting blocks 74, cover presser 41 upper sliding type is connected with pressing frame 71, pressing icon is arranged on the top of pressing frame 71, is provided with limit assembly on installation frame 2; Limit assembly includes n-shaped limit rod 72 and limit spring 73, installs The front and rear sides of the top of the frame 2 are slidably connected with n-shaped limiting rods 72, the top of the n-shaped limiting rods 72 is in contact with the bottom of the limiting block 74, and the four corners of the bottom of the n-shaped limiting rods 72 are all inclined-plane settings, and the n-shaped limiting rods 72 Limiting springs 73 are connected between both sides and the installation frame 2 .

When the personnel use the power switch, there will be the following three situations: first, when the non-staff triggers the start switch 3, the non-staff can know by pressing the icon, and press the pressing frame 71, so that the pressing frame 71 moves to Moving down, the pressing frame 71 drives the n-shaped limiting rod 72 to move outward, and the limiting spring 73 is compressed. At this time, the starting switch 3 is not triggered, and non-staff members cannot trigger the starting switch 3, and then release the pressing frame 71 , under the action of the limiting spring 73, it will drive the n-shaped limiting rod 72 to reset, and due to the slopes provided at the four corners of the lower part of the pressing frame 71, it will drive the pressing frame 71 to move upwards and reset; second, if the staff is triggering When starting the switch 3, after pressing the pressing frame 71, the n-shaped limiting rod 72 no longer limits the position of the limiting block 74, and the staff knows that the cover presser 41 can be moved downwards, thereby triggering the starting switch 3, But non-staff just can't know the step of triggering start switch 3, can carry out invalid operation because of pressing icon; , so the cover presser 41 will not move downwards, so that the alarm 42 can be avoided and the trouble of the staff can be reduced, and the safety of the power switch can be improved at the same time.

As shown in Fig. 2 and Fig. 11, also include auxiliary push mechanism 8, auxiliary push mechanism 8 includes guide sleeve 81 and auxiliary push rod 82, all front and back symmetrically welded with guide sleeve 81 on the left and right sides of mounting frame 2 top, guide sleeve Auxiliary push rods 82 are slidably connected on the top 81, and the outer sides of the auxiliary push rods 82 are respectively connected with the adjacent push plates 51.

When the staff moves the push plate 51 to the inside, it will drive the auxiliary push rod 82 to move inward, so that the auxiliary push rod 82 pushes the n-shaped restricting rod 72 to the outside and no longer restricts the restricting block 74, so that the covering press can be released 41, so that the staff presses the cover presser 41, when the push plate 51 moves to the outside, it will drive the auxiliary push rod 82 to move to the outside and reset, so that the n-shaped limit rod 72 moves to the inside and resets to limit the limit block 74 again From the above operations, it can be known that when the staff presses the push plate 51, the effect of automatically releasing the cover presser 41 is realized, so that the efficiency of triggering the start switch 3 can be improved.
