DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3The timing switch protection device shown in the figure to prevent the danger of misoperation includes a switch box 1 and a button 2, a protrusion 3 and a rotating handle 5. The rotating handle 5 is in an arc-shaped structure on the side close to the cover 4, which can facilitate the spring rod 7 to be inserted into the gap of the rotating handle 5. The switch box 1 is located on one side of the rotating handle 5 and is contacted and connected with a fixed cover 6. The fixed cover 6 is rotatably connected in the cover 4. A first through hole is opened on one side of the fixed cover 6 and a spring rod 7 is inserted in the first through hole. A limit block 9 is arranged on one side of the spring rod 7. The limit block 9 has a circular structure and is fixedly connected to one side of the rotating handle 5. The limit block 9 is flush with the uppermost side of the rotating handle 5. A timetable is set on the rotating handle 5, and the 0 scale of the rotating handle 5 corresponds to the limit block 9. At the same time, the rotating handle 5 is composed of a shell, a knob, a contact, a conductive member and a fixing device. When the knob is rotated, it can be transmitted to the contact through the internal structure of the switch box 1 to make it contact or separate. When the contact When the points are in contact, the circuit is closed, allowing current to pass, thereby starting or maintaining the operating state of the device. When the contacts are separated, the circuit is disconnected, the current cannot pass, and the device will stop running or remain in the off state. At the same time, a clock-like mechanical timing device can be set to preset the on-off time of the switch. Once the preset time point is reached, the timing mechanism will automatically operate the contacts to achieve automatic on-off of the circuit. A card slot 10 is provided on both sides of the fixed cover 6 that are away from each other, a second through hole is provided on one side of the cover 4, and a spring telescopic rod 12 is inserted into the second through hole. A card strip 11 is fixedly connected to the spring telescopic rod 12, and the card strip 11 is squeezed to extend the spring telescopic rod 12, and the card strip 11 enters the card slot 10, thereby regulating the rotation of the fixed cover 6. When the 0 scale of the rotating handle 5 is at the topmost side, the rotating card strip 11 drives the fixed cover 6 to rotate, and the spring rod 7 is squeezed and contracted by the limit block 9. At this time, the shell pulls open the cover 4.

[0018] The card strip 11 corresponds to the arc hole 13 , which is located on the cover 4 and at both ends of the spring telescopic rod 12 . The card strip 11 is manually inserted and squeezed by a tool to connect the card strip 11 to the card slot 10 .

[0019] A squeezing rod 14 is inserted into the arc-shaped hole 13 . The squeezing rod 14 is fixedly connected to two sides of the clamping strip 11 that are away from each other. The clamping strip 11 can be squeezed conveniently by pressing the squeezing rod 14 .

[0020] The first through hole contacts the limiting plate 8 , and the limiting plate 8 is fixedly connected to the spring rod 7 . The limiting plate 8 can improve the stability of the extension and retraction of the spring rod 7 by connecting with the spring rod 7 .

[0021] Among them, the limit block 9 corresponds to the ball 15, and the ball 15 is rotatably embedded in the end of the spring rod 7. By setting the ball 15, the friction between the spring rod 7 and the limit block 9 is reduced when the spring rod 7 is compressed and stretched.

[0022] Working principle: Turn the rotating handle 5 and set the time of the timing switch, then close the cover 4, the spring rod 7 is squeezed by one side of the arc surface of the rotating handle 5 to shrink, and the cover 4 is in contact with the switch box 1. At this time, after a certain period of time, the 0 scale and the limit block 9 of the rotating handle 5 return to the upper side, which greatly prevents non-staff from accidentally touching or operating. The staff pushes the squeezing rod 14 with a tool, and the card strip 11 moves into the card slot 10 of the fixed cover 6. Rotating the squeezing rod 14 can make the spring rod 7 on the bottom side of the fixed cover 6 squeezed by the limit block 9. When the ball 15 reduces the friction, the spring rod 7 shrinks to be flush with the upper side of the rotating handle 5, and the cover 4 can be opened.

[0023] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0024] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
