[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 5As shown, a spring breakage stopping device described in an embodiment of the utility model comprises a placing plate 8; the middle part of the placing plate 8 is rotatably connected to a rotating shaft 81, a motor 82 is fixedly connected to the bottom of the placing plate 8, a spring is fixedly connected to the side wall of the rotating shaft 81, the outer wall of the spring is sleeved with a protective cover 1, the side wall of the protective cover 1 is slidably connected to two first support rods 11, the top ends of the two first support rods 11 are fixedly connected to an extrusion rod 13, the other ends of the two first support rods 11 are fixedly connected to a pressing handle 14, a first spring 12 is fixedly connected between the two pressing handles 14 and the outer wall of the protective cover 1, when working, press the pressing handle 14 to push the first support rod 11 in, sleeve the protective cover 1 on the outside of the spring, release the pressing handle When hand 14 is used, the mainspring will block the squeezing rod 13 and prevent the first spring 12 from bouncing open. When the mainspring is rotated, the squeezing rod 13 moves, and the first support rod 11 slides to shrink the first spring 12. When the mainspring is operating and the mainspring suddenly breaks, the mainspring will become loose and bounce open. The first spring 12 will slide and pop out the first support rod 11, so that the squeezing rod 13 will immediately press the mainspring to prevent movement. When the mainspring breaks, the internal mainspring will be impacted, causing the mainspring to fly after breaking. When the mainspring breaks, fixing it can prevent the mainspring from shaking inside after breaking in time, so that the mainspring can be stopped from being used, thereby reducing the damage of some components and reducing the problem of the mainspring being worn out internally after failing to stop in time after breaking.
[0024] like Figure 3 As shown, the top of the protective cover 1 is slidably connected to multiple groups of pressure rods 2, and the ends of the multiple groups of pressure rods 2 are fixedly connected to cover plates 22. Multiple second springs 21 are fixedly connected between the bottom of the cover plate 22 and the protective cover 1. Two second support rods 23 are fixedly connected to the top of the protective cover 1. The two second support rods 23 are in opposite positions. The tops of the two second support rods 23 are fixedly connected to casters 24. The side wall of the protective cover 1 is provided with two small holes, and the two small holes are both at the top of the first support rod 11. Two tension ropes 25 are fixedly connected to the top of the cover plate 22. The two tension ropes 25 are slidably connected to the middle of the casters 24, and the other ends of the tension ropes 25 pass through The small hole is fixedly connected to one end of the first support rod 11. During operation, when the first support rod 11 is pushed in, the tension rope 25 is pulled, and the tension rope 25 pulls up the cover plate 22 through the caster 24. When the cover plate 22 is lowered, multiple pressure rods 2 are inserted into the spring gap, and the second spring 21 is used to reduce the collision between the cover plate 22 and the protective cover 1. When the cover plate 22 descends, the second spring 21 can be used for buffering to reduce the wear between the cover plate 22 and the protective cover 1. By inserting multiple groups of pressure rods 2 into the spring, excessive twisting of the spring can be reduced during use, and the breakage of the spring due to twisting with the bottom rotating shaft 81 during use can be reduced.
[0025] like Figure 5As shown, the bottom ends of the two squeezing rods 13 are fixedly connected with connecting strips 3, and the other ends of the two connecting strips 3 are fixedly connected with first magnets 31. The bottom end of the protective cover 1 is fixedly connected with two second magnets 32, and the two second magnets 32 are in opposite positions. During operation, when the clockwork spring breaks, the squeezing rod 13 presses the clockwork spring, and during the pressing process, the first magnet 31 and the second magnet 32 side walls are attracted to each other, so that when the clockwork spring breaks, the squeezing rod 13 can move toward the protective cover 1 to effectively make the squeezing rod 13 fit the clockwork spring more closely, thereby strengthening its fixing effect on the clockwork spring.
[0026] like Figures 4 to 5 As shown, multiple groups of rubber sheets 4 are fixedly connected on both sides of the two extrusion rods 13, and steel wires are supported inside the multiple groups of rubber sheets 4. During operation, when the extrusion rod 13 is close to the clockwork spring, the rubber sheet 4 is used to resist the clockwork spring, so that the clockwork spring is in contact with the rubber sheet 4 to be fixed. The steel wire is arranged inside the rubber sheet 4 to support the rubber sheet 4. When the clockwork spring is fixed after breaking, it can fit tightly on the surface of the clockwork spring, has an anti-slip effect, reduces the movement of the clockwork spring after breaking, and reduces the friction with the clockwork spring.
[0027] like Figure 3 As shown, multiple groups of elastic ropes 5 are connected to the bottom of multiple groups of pressure rods 2, and the elastic ropes 5 are located between each pair of pressure rods 2 that are close to each other. During operation, after the clockwork spring breaks, the top of the clockwork spring can be fixed by the elastic ropes 5. The elastic ropes 5 have a certain elasticity, which can reduce excessive twisting of the clockwork spring when the clockwork spring is rotated for operation, and can rebound freely and effectively fix both sides of the clockwork edge.
[0028] like Figures 1 to 5 As shown, two grooves are provided at the top of the placement plate 8, and two third magnets 6 are fixed in the two grooves. The two third magnets 6 are at the same position as the two second magnets 32. When working, when the protective cover 1 is put on the outside of the clockwork spring, the third magnets 6 and the bottom of the second magnets 32 are attracted to each other, so that the protective cover 1 is fixed to the top of the placement plate 8, and the protective cover 1 can be fixed when it is put on the outside of the clockwork, thereby reducing the shaking during work.
[0029] like Figures 1 to 3 As shown, two sponge strips 7 are fixedly connected to the bottom of the protective cover 1, and the two sponge strips 7 are respectively on both sides of the second magnet 32. During operation, when the protective cover 1 is put on the outside of the mainspring, the sponge strips 7 cushion it. After the protective cover 1 is placed, the cushioning can reduce the friction between the protective cover 1 and the placement plate 8 and reduce damage.
[0030] When working, press and hold the pressing handle 14 to push the first support rod 11 in, and put the protective cover 1 on the outside of the clockwork spring. When the pressing handle 14 is released, the clockwork will block the squeezing rod 13 to prevent the first spring 12 from bouncing open. When the clockwork is rotated, the squeezing rod 13 moves, and the first support rod 11 slides to shrink the first spring 12. When the clockwork spring is running and the clockwork suddenly breaks, the clockwork will become loose and bounce open. The first spring 12 will slide and pop out the first support rod 11, so that the squeezing rod 13 immediately presses the clockwork to prevent movement. When the first support rod 11 is pushed in, the tension rope 25 is pulled, and the tension rope 25 pulls up the cover plate 22 through the casters 24. When the cover plate 22 is lowered, it is inserted into the clockwork gap through multiple pressure rods 2. The second spring 21 reduces the collision between the cover plate 22 and the protective cover 1. When the spring breaks, the squeezing rod 13 compresses the spring. During the compressing process, the first magnet 31 and the second magnet 32 side walls are attracted to each other. When the squeezing rod 13 is close to the spring, the rubber sheet 4 is used to press against the spring, so that the spring contacts the rubber sheet 4 to be fixed. A steel wire is arranged inside the rubber sheet 4 to support the rubber sheet 4. After the spring breaks, the top of the spring can be fixed by the elastic rope 5. When the protective cover 1 is put on the outside of the spring, the third magnet 6 and the bottom of the second magnet 32 are attracted to each other, so that the protective cover 1 is fixed on the top of the placement plate 8. When the protective cover 1 is put on the outside of the spring, the sponge strip 7 cushions it.
