At the same time, when the connecting block 502 rotates downward, the bottom end of the connecting block 502 presses downward against the end of the torsion spring 505, so that the torsion spring 505 forms a rotational force. When the protective cover 4 needs to be opened, the fixation between the front side of the protective cover 4 and the base 2 is released, so that the protective cover 4 loses its resistance, and then the connecting block 502 no longer presses against the torsion spring 505. At this time, the torsion spring 505 releases energy and drives the connecting block 502 to rotate back and reset. The connecting block 502 drives the protective cover 4 to bounce upward and no longer engage with the groove 3. Therefore, there is no need to manually pull open the protective cover, making the operation more convenient and flexible, and improving the operating efficiency.

[0022] A slide seat 7 is installed on the other side of the base 2, and a slider 6 is slidably connected inside the slide seat 7. The slider 6 is installed on the other side of the protective cover 4. The slide seat 7 and the slider 6 are perpendicular to each other. The slider 6 is an inverted "L" shape structure, and the slide seat 7 is a "U" shape structure. The slider 6 connected to the protective cover 4 is engaged with the slide seat 7 on the base 2, so as to quickly fix the protective cover 4.

[0023] The slider 6 and the slide seat 7 are limited by a limiting structure 8, and the limiting structure 8 includes a clamping block 801 and a limiting hole 802. The clamping block 801 is slidably connected to the side of the slide seat 7, and a limiting hole 802 is provided at the end of the slider 6. The clamping block 801 is engaged in the limiting hole 802. A pull plate 807 is fixedly connected to the end of the clamping block 801, and the other end of the pull plate 807 is fixedly connected to a guide rod 804. A countersunk hole 806 is provided at one end of the slide seat 7 close to the base 2, and the guide rod 804 is slidably connected to the countersunk hole 806. A spring 803 is sleeved on the guide rod 804, and the other end of the guide rod 804 is fixedly connected to a push plate 805, one end of the spring 803 abuts against the inside of the countersunk hole 806, and the other end of the spring 803 abuts against the inner side of the push plate 805; the protective cover 4 is continuously pressed, The protective cover 4 drives the slider 6 to slide downward, and the end of the slider 6 contacts the block 801 downward, so that the block 801 slides to the outside of the slide seat 7, and the block 801 drives the pull plate 807 to move outward, and the pull plate 807 drives the guide rod 804 to slide in the countersunk hole 806, and the guide rod 804 drives the push plate 805 to move in the direction of the slide seat 7, and the push plate 805 contacts the spring 803 to shrink. When the limiting hole 802 on the slider 6 is aligned with the block 801, the block 801 loses its resistance force, thereby causing the spring 803 to lose its resistance force, and the spring 803 is reset, driving the block 801 to engage into the limiting hole 802, so that the protective cover 4 is engaged with the groove 3 on the base 2, so that the protective cover 4 protects the switch body 1, and the operation is simple and flexible, which not only makes the protective cover 4 more firmly engaged with the groove 3 on the base 2, but also facilitates the operator to operate with one hand.

[0024] A circle of grooves 3 are provided at the top of the base 2, and the protective cover 4 is engaged in the groove 3. A convex ring is provided on the inner periphery of the base 2, and the end of the convex ring is in a sloped structure. The setting of the groove 3 facilitates the engagement of the protective cover 4, and the setting of the convex ring makes the protective cover 4 and the base 2 more tightly connected, so that the sealing performance of the entire protective device is better, and the convex ring is set as a slope, which is convenient for the protective cover 4 to be quickly engaged.

[0025] The countersunk hole 806 has a smaller diameter at one end facing the block 801, and the end of the block 801 is in an inclined structure. The setting of the countersunk hole 806 enables the spring 803 to form a resistance force, and the block 801 is set as an inclined surface, which has a guiding effect on the downward sliding of the slider 6, thereby making the limiting structure 8 more flexible in operation.

[0026] When the utility model is in use, the protective cover 4 is first pressed downward, and the protective cover 4 drives the connecting block 502 to rotate on the rotating shaft 503. At the same time, when the connecting block 502 rotates downward, the bottom end of the connecting block 502 presses downward against the end of the torsion spring 505, so that the torsion spring 505 forms a rotational force, and the protective cover 4 is continuously pressed, and the protective cover 4 drives the slider 6 to slide downward, and the end of the slider 6 presses downward against the block 801, so that the block 801 slides to the outside of the slide seat 7, and the block 801 drives The pull plate 807 moves outward, and the pull plate 807 drives the guide rod 804 to slide in the countersunk hole 806. The guide rod 804 drives the push plate 805 to move in the direction of the slide seat 7. The push plate 805 resists the spring 803 to shrink. When the limiting hole 802 on the slider 6 is aligned with the block 801, the block 801 loses its resistance, so that the spring 803 loses its resistance. The spring 803 is reset, driving the block 801 to engage with the limiting hole 802, so that the protective cover 4 is aligned with the bottom The groove 3 on the seat 2 is engaged, so that the protective cover 4 plays a protective role on the switch body 1, and the operation is simple and flexible, not only making the protective cover 4 more firmly engaged with the groove 3 on the base 2, but also convenient for the operator to operate with one hand; when it is necessary to open the protective cover 4, the push plate 805 is pushed, and the push plate 805 or the pull plate 807 is pulled to drive the guide rod 804 to slide to the other side of the countersunk hole 806, and at the same time drive the spring 803 to contract, the guide rod 804 drives the pull plate 807 to move, and the pull plate 807 drives the card block 801 to slide outward, so that the card block 801 is no longer engaged with the limit hole 802, so that the protective cover 4 loses its resistance, and then the connecting block 502 no longer resists the torsion spring 505. At this time, the torsion spring 505 releases energy, drives the connecting block 502 to rotate back and reset, and the connecting block 502 drives the protective cover 4 to bounce upward and no longer engage with the groove 3. Therefore, there is no need to manually pull open the protective cover, making the operation more convenient and flexible, and improving the operating efficiency.
