Specific implementation plan

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 5 The utility model provides a technical solution: a protective structure, including a baffle 1, an elastic mechanism 2 is arranged below the baffle 1, and a rotating mechanism 3 is arranged below the elastic mechanism 2;

[0023] The elastic mechanism 2 includes a first support rod 201 fixedly connected to the lower part of the baffle 1, a first groove 202 is arranged inside the first support rod 201, the width of the first groove 202 is greater than the diameter of the limit plate 204, and the height of the first groove 202 is greater than the diameter of the limit plate 204, so that the limit plate 204 can move up and down inside the first groove 202, a spring 203 is fixedly connected to the inner side of the first groove 202, the lower end of the spring 203 is fixedly connected to the limit plate 204, and the lower surface of the first groove 202 is connected to a hole Hole 205, the lower end of the limiting plate 204 is fixedly connected with the second support rod 206, the width of the hole 205 is smaller than the diameter of the limiting plate 204, and the central axis of the hole 205 is on the same straight line as the central axis of the first groove 202, so that the limiting plate 204 will not move out of the inner side of the hole 205, the appearance and structural shape of the limiting plate 204 is spherical, and the central axis of the limiting plate 204 is on the same straight line as the central axis of the second support rod 206, so that the first support rod 201 can swing on the outer side of the limiting plate 204.

[0024] The rotating mechanism 3 includes a first supporting plate 301 fixedly connected to the lower end of the second supporting rod 206, and the two ends of the first supporting plate 301 are fixedly connected to the second supporting plate 302. A third supporting plate 303 is arranged below the second supporting plate 302, and a slide groove 304 is arranged inside the third supporting plate 303. A slider 305 is arranged inside the slide groove 304. The upper end width of the slider 305 is smaller than the lower end width of the slider 305, and the upper end outer side surface of the slider 305 fits the inner side surface of the slide groove 304, so that the slider 305 can rotate inside the slide groove 304, but The slider 305 will not move out of the inner side of the slide groove 304. Elastic rubber pads 308 are fixedly connected to both ends of the slider 305. The lower end of the third support plate 303 is fixedly connected to a base 309. The slider 305 is fixedly connected to the second support plate 302. The appearance structure of the second support plate 302 is an arc shape, and the lower surface of the second support plate 302 is in contact with the upper surface of the third support plate 303, so that the second support plate 302 can rotate on the outer side of the third support plate 303. A high-pressure pump is provided, including any one of the above-mentioned protective structures for the high-pressure pump.

[0025] When an object with an inclined direction impacts the baffle 1, the force acts on the baffle 1 and is then transmitted to the first support rod 201. Since the width of the first groove 202 is greater than the diameter of the limiting plate 204, and the height of the first groove 202 is greater than the diameter of the limiting plate 204, the first support rod 201 is tilted, so that the force acts on the spring 203, so that the force disappears as a force that bends the spring 203. When the force is too large, since the force is inclined, the first support rod 201 drives the limiting plate 204 to rotate, and drives the second support rod 206 and the first support plate 301 to rotate, so that the second support plate 302 rotates. Since the appearance and structural shape of the second support plate 302 is an arc shape, and the lower surface of the second support plate 302 fits the upper surface of the third support plate 303, the force acts on the upper part of the elastic rubber pad 308, and the force disappears as a force compressed by the elastic rubber pad 308, thereby reducing the force transmitted to the upper part of the high-pressure pump, thereby reducing the vibration of the high-pressure pump and reducing the damage to the high-pressure pump.
