[0031] EMBODIMENT

[0032] A small animal prevention device for live working, as shown in Figures 1-3As shown, it comprises a fixed line segment 1, a fixed sleeve 2 mounted on the fixed line segment 1, and a rotating ball 3 assembled with the fixed sleeve 2, which can rotate 360° around the fixed line segment 1. The fixed sleeve 2 comprises a lower sleeve shell 21 covering the fixed line segment 1, a movable buckle 23 hingedly connected to the lower sleeve shell 21 and buckled to the upper sleeve shell 22, and a compression assembly 24 located between the lower sleeve shell 21 and the upper sleeve shell 22 for compressing the fixed line segment 1. The lower sleeve shell 21 is hingedly connected to the upper sleeve shell 22 and buckled closed by the movable buckle 23. The rotating ball 3 comprises a lower hemisphere sleeve 31 sleeved below the fixed sleeve 2, and an upper hemisphere sleeve 32 sleeved above the fixed sleeve 2 and assembled with the lower hemisphere sleeve 31. The structure of the upper hemisphere sleeve 32 is consistent with that of the lower hemisphere sleeve 31.

[0033] In this scheme, the rotating ball can rotate 360° around the fixed line segment on the fixed sleeve. This design can flexibly cope with small animals invading from different directions. In addition, the fixed sleeve comprises upper and lower sleeve shells, and the lower sleeve shell is connected to the upper sleeve shell through the movable buckle. This structure makes the device easy to install and disassemble. The rotating ball is composed of an upper hemisphere sleeve and a lower hemisphere sleeve, and the structures of the two are consistent. This sleeved design facilitates the assembly and replacement of the rotating ball, reducing maintenance costs.

[0034] As shown in Figure 3 The two ends of the lower sleeve shell 21 are integrally formed with lower sleeve shell half-cylinder barrels 211 covering the lower surface of the fixed line segment 1. Since the two ends of the lower sleeve shell perfectly fit the lower surface of the fixed line segment 1, the stability of the device can be increased, preventing shaking or loosening during use.

[0035] As shown in Figure 3 The side of the upper sleeve shell 22 facing the movable buckle 23 is provided with a buckle groove 221, the two ends of the upper sleeve shell 22 are integrally formed with upper sleeve shell half-cylinder barrels 222 covering the upper surface of the fixed line segment 1, a through hole 223 is formed in the middle of the top of the upper sleeve shell 22, and a copper nut 224 is fixed during casting of the upper sleeve shell 22, and the copper nut 223 is on the same axis as the through hole 223.

[0036] In this scheme, the side of the upper sleeve shell 22 facing the movable buckle 23 is provided with a buckle groove 221, which can be connected with the movable buckle 23, improving the stability. The two ends of the upper sleeve shell 22 are integrally formed with upper sleeve shell half-cylinder barrels 222 covering the upper surface of the fixed line segment 1, which can increase the stability and prevent shaking or loosening during use.

[0037] In addition, the upper sleeve 22 is provided with a through hole 223 in the middle of the top, and a copper nut 224 is fixed in the through hole 223 during the injection molding of the upper sleeve 22. The copper nut 224 is on the same axis as the through hole 223. This design facilitates installation and disassembly, and also makes the device more secure. The one-piece design of the upper sleeve 22 avoids problems such as loosening at the connection, reducing maintenance costs.

[0038] As shown in Figure 3 The compression assembly 24 includes a headless stud 241 with a connecting end at the lower end, a fastening anti-slip metal sheet 242 with a connecting groove on the upper surface that can cooperate with the connecting end of the headless stud 241, and a pressing block 243 located below the fastening anti-slip metal sheet 242 and having an arc-shaped lower surface.

[0039] In this scheme, after the lower sleeve 21 and the upper sleeve 22 are wrapped and fastened by the movable buckle 23 and installed on the fixed wire segment 1, the headless stud 241 is inserted through the through hole 223 and screwed into the copper nut 224. At this time, the headless stud 241 with a connecting end is inserted into the fastening anti-slip metal sheet 242 with a connecting groove, and the fastening anti-slip metal sheet 242 is pressed downward, so that the pressing block 243 below the fastening anti-slip metal sheet 242 presses against the fixed wire segment 1, thereby completing the fixed installation of the fixed sleeve 2.

[0040] The fastening anti-slip metal sheet 242 with a connecting groove on the upper surface can cooperate with the connecting end of the headless stud 241 to form a reliable connection. The pressing block 243 located below the fastening anti-slip metal sheet 242 has an arc-shaped lower surface, which exerts pressure on the fixed wire segment 1 when the fastening anti-slip metal sheet 242 is pressed downward, thereby enabling the fixed sleeve 2 to be securely installed on the fixed wire segment 1. This design can effectively prevent the device from loosening or shifting during use.

[0041] As shown in Figure 4 The lower half spherical sleeve 31 includes a rotating inner shell 311 in the shape of a hemisphere that can rotate around the fixed wire segment 1 on the fixed sleeve 2, a shell edge protrusion 312 assembled on the outer side of the opening of the rotating inner shell 311, a rotating outer shell 313 wrapped around the rotating inner shell 311 that can rotate on the rotating inner shell 311, a shell surface protrusion 314 assembled on the surface of the rotating outer shell 313, and a pressing buckle 315 passing through the rotating outer shell 313 and buckling with the rotating inner shell 311.

[0042] In this scheme, the rotating inner shell 311 in the shape of a hemisphere can rotate around the fixed wire segment 1 on the fixed sleeve 2, enabling the device to effectively block small animals in different directions. This design improves the applicability and flexibility of the device.

[0043] In this scheme, the shell edge protrusion 312 assembled on the outer side of the opening of the rotating inner shell 311 can cooperate with the shell surface protrusion 314 of the rotating outer shell 313 to form a reliable connection. This design can ensure the stability of the relative position between the rotating outer shell 313 and the rotating inner shell 311, thereby ensuring the normal operation of the device.

[0044] In this scheme, the rotating outer shell 313 covering the rotating inner shell 311 can rotate on the rotating inner shell 311, so that the device can effectively prevent small animals in different directions. This design improves the applicability and flexibility of the device. The shell surface protrusion 314 assembled on the surface of the rotating outer shell 313 can cooperate with the shell edge protrusion 312 to form a reliable connection. This design can ensure the stability of the relative position between the rotating outer shell 313 and the rotating inner shell 311, thereby ensuring the normal operation of the device.

[0045] In this scheme, the pressure buckle 315 passing through the rotating outer shell 313 and buckling with the rotating inner shell 311 can fix the rotating outer shell 313 and the rotating inner shell 311 together to prevent the relative position from changing. This design can ensure that the device will not be loose or fall off during use

[0046] As shown in Figures 5-6 , the rotating inner shell 311 includes a rotating inner shell body 3111, a semicircular shaft sleeve 3112 integrally formed at both ends of the rotating inner shell body 3111, a rotating joint 3113 with a circular hole integrally formed on the outside of the bottom of the rotating inner shell 311, a spring clamp mounting seat 3114 integrally formed on the outside of the side of the rotating inner shell 311, two parallel slide grooves 3115 vertically arranged on the outside of the rotating inner shell body 3111, and a limiting groove 3116 located between the two slide grooves 3115.

[0047] In this scheme, the rotating inner shell body is integrally formed, which has the characteristics of simple structure and high strength, can effectively support and fix other components, and ensure the stability and reliability of the device. The semicircular shaft sleeve located at both ends of the rotating inner shell body 3111 can provide good rotating support and be tightly connected with other cooperating components to ensure smooth rotation of the rotating inner shell.

[0048] As shown in Figure 7 , the shell edge protrusion 312 includes an arc-shaped strip buckle plate 3121 with protrusions welded on the outside, a slide strip 3122 formed by bending inward from both ends of the strip buckle plate 3121, and a plug buckle 3122 integrally formed at the center of the strip buckle plate 3121.

[0049] In the present scheme, the shell edge protrusion 312 is assembled before the rotating outer shell 313 is assembled with the rotating inner shell 311. First, the upper end sliding bar 3122 of the strip-shaped buckle assembly plate 3121 is aligned with the sliding groove 3115, and then the strip-shaped buckle assembly plate 3121 is pushed to slide and make the plug buckle 3122 abut against the limiting groove 3116. At this time, the strip-shaped buckle assembly plate 3121 is tightly fitted. Then, the rotating outer shell 313 is buckled on the rotating inner shell 311 and assembled by the pressing buckle 315. The edge of the rotating outer shell 313 abuts against the shell edge protrusion 312, so that the shell edge protrusion 312 is not easy to loosen.

[0050] As shown in Figures 8-9 , the rotating outer shell 313 includes a rotating outer shell body 3131, a buckle assembly part 3132 integrally formed at the edge of the rotating outer shell body 3131, equidistantly distributed spherical plug holes 3133 formed at one end of the bottom surface of the rotating outer shell body 3131, and an outwardly protruding rotating assembly seat 3134 integrally formed at the central part of the bottom of the rotating outer shell body 3131.

[0051] In the present scheme, when the rotating outer shell 313 is buckled on the surface of the rotating inner shell 311, the rotating joint 3113 is embedded in the interior of the rotating assembly seat 3134. Then, the pressing buckle 315 is pressed from the exterior of the rotating assembly seat 3134, passes through the rotating assembly seat 3134, and then enters the circular hole of the rotating joint 3113. The movable installation of the rotating outer shell 313 and the rotating inner shell 311 is completed, so that the rotating outer shell 313 can rotate around the rotating joint 3113 as the center point on the rotating inner shell 311.

[0052] As shown in Figure 10 , the shell surface protrusion 314 includes a petal-shaped buckle assembly plate 3141 with protrusions externally welded and arranged in an arc shape, a buckle head 3142 integrally formed at the upper end of the petal-shaped buckle assembly plate 3141, and an embedded buckle 3143 integrally formed at the inner side of the lower end of the petal-shaped buckle assembly plate 3141.

[0053] In the present scheme, the embedded buckle 3143 at the inner side of the lower end of the petal-shaped buckle assembly plate 3141 is obliquely inserted into the spherical plug hole 3133 of the rotating outer shell 313. Then, the buckle head 3142 at the upper end of the petal-shaped buckle assembly plate 3141 is buckled with the buckle assembly part 3132 of the rotating outer shell 313. The fixation of the shell surface protrusion 314 is completed. Finally, the shell surface protrusion 314 is sequentially assembled on the rotating outer shell 313 in this way.

[0054] In the present embodiment, the rotating outer shell 313 can rotate 360° around the rotating inner shell 311 on the rotating inner shell 311.

[0055] The above embodiments of the present application are not intended to limit the scope of the present application, and the embodiments of the present application are not limited thereto. Any other modifications, replacements, or changes to the above structure of the present application, which are made according to the above content of the present application, in accordance with the ordinary technical knowledge and common practices in the art, without departing from the above basic technical idea of the present application, shall fall within the scope of protection of the present application.
