DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] Example 1: See Figure 1-Figure 5The present invention provides a technical solution: a power box with a mouse repelling function, comprising a support mechanism 1, the support mechanism 1 comprising a power cabinet 101, the front of the power cabinet 101 is rotatably connected to a cabinet door 102 through a hinge, the outer surface of the power cabinet 101 is provided with a first heat dissipation groove 103, the top of the power cabinet 101 is fixedly connected to a fixing rod 106, a first sliding groove 107 is provided on a side of the power cabinet 101 close to the fixing rod 106, a threaded rod 108 is fixedly connected to an outer wall of the power cabinet 101 on a side away from the fixing rod 106, a support frame 109 is fixedly connected to an outer wall of the threaded rod 108 on a side away from the power cabinet 101, a groove 110 is provided on an outer surface of the power cabinet 101 on a side close to the threaded rod 108, and also includes: The protection mechanism 2 includes a force-bearing frame 201 movably sleeved on the outer surface of the power cabinet 101, an auxiliary component 209 is arranged on the top inner wall of the force-bearing frame 201, a second heat dissipation groove 202 is provided on the outer surface of the force-bearing frame 201, a roller 203 is rotatably connected to the inner wall of one side of the force-bearing frame 201 close to the second heat dissipation groove 202 through a rotating shaft, and the roller 203 can prevent mice from climbing on the side wall of the force-bearing frame 201, a fixing ring 204 is fixedly connected to the bottom inner wall of the force-bearing frame 201, a second sliding groove 205 is arranged on the outer surface of the fixing ring 204 away from the force-bearing frame 201, and an expelling mechanism 3 is arranged inside the fixing ring 204, and the second heat dissipation groove 202 It is used to assist the power cabinet 101 in dissipating heat. When a mouse contacts the force-bearing frame 201 that is movably connected to the outside of the power cabinet 101, the force-bearing frame 201 will slide downward under the action of the mouse's gravity. At this time, the second heat dissipation groove 202 on the outer surface of the force-bearing frame 201 and the first heat dissipation groove 103 on the outer surface of the power cabinet 101 will be misaligned, thereby effectively preventing the mouse from drilling into the interior of the power cabinet 101 through the first heat dissipation groove 103. During the sliding of the force-bearing frame 201, its top will apply a certain pressure to the cabinet door 102, so that the gap between the cabinet door 102 and the power cabinet 101 becomes smaller, thereby preventing the mouse from entering the interior of the power cabinet 101 through the gap between the two.
[0024] The outer wall of the force-bearing frame 201 is rotatably connected to an auxiliary plate 206 through a rotating shaft, and the outer wall of the auxiliary plate 206 is fixedly connected to a tilting rod 208, and the outer wall of the auxiliary plate 206 on the side close to the power cabinet 101 is fixedly connected to a fixing block 207, and the outer wall of the power cabinet 101 on the side away from the auxiliary plate 206 is fixedly connected to a flexible gasket 104, and the outer wall of the flexible gasket 104 on the side away from the power cabinet 101 is fixedly connected to a protrusion 105, and the protrusion 105 is made of rubber material, which can effectively reduce the impact of the vibration of the protrusion 105 on the power cabinet 101. When the force-bearing frame 201 slides downward, the auxiliary plate 206 will contact the protrusion 105 through the fixing block 207, causing the force-bearing frame 201 to vibrate, and the flexible gasket 104 can buffer the vibration of the protrusion 105 caused by the reaction force, thereby reducing the impact of the force-bearing frame 201 on the internal electrical components of the power cabinet 101.
[0025] Example 2: Please refer to Figure 6 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary component 209 includes a first rotating rod 2091 rotatably connected to the inner wall of the force-bearing frame 201, the end of the first rotating rod 2091 away from the force-bearing frame 201 is rotatably connected to the first sliding block 2092 through a rotating shaft, the first sliding block 2092 is slidably connected to the inner wall of the first sliding groove 107, the first sliding groove 107 is used to limit the sliding direction and sliding distance of the first sliding block 2092, the inner wall of the first sliding block 2092 is rotatably connected to the second rotating rod 2093 through a rotating shaft, the end of the second rotating rod 2093 away from the first sliding block 2092 is rotatably connected to the second sliding block 2094 through a rotating shaft, and the second sliding block 2094 is movably sleeved on the fixed The outer surface of the rod 106, the fixed rod 106 is used to limit the sliding distance of the second sliding block 2094. When the force-bearing frame 201 slides downward due to the gravity of the mouse, the force-bearing frame 201 will use the first rotating rod 2091 to push the first sliding block 2092 to slide on the inner wall of the first sliding groove 107. The first sliding block 2092 pushes the second sliding block 2094 through the second rotating rod 2093 to slide on the outer surface of the fixed rod 106. The second sliding block 2094 ensures that the sliding distance of the first sliding block 2092 is consistent through the second rotating rod 2093, thereby ensuring that the sliding distance of each part of the force-bearing frame 201 is equal, effectively preventing the force-bearing frame 201 from tilting and avoiding it from generating large friction with the power cabinet 101.
[0026] A first spring 2095 is fixedly connected to the outer wall of the second sliding block 2094 on one side away from the second rotating rod 2093.

The first spring 2095 is movably sleeved on the outer surface of the fixed rod 106. The first spring 2095 is used for resetting the second sliding block 2094. When the second sliding block 2094 slides, it will squeeze the first spring 2095. Since the first spring 2095 is elastic, it will return to its original shape after being deformed by force, thereby making the second sliding block 2094 reciprocate on the outer surface of the fixed rod 106. The reciprocating sliding of the second sliding block 2094 can keep the force-bearing frame 201 in a vibrating state for a short time, further enhancing the mouse-repelling effect of the force-bearing frame 201.

Under the action of the mouse's gravity, the force-bearing frame 201 slides downward, and the force-bearing frame 201 drives the rotating frame 301 to move downward along the threaded rod 108 with the help of the fixed ring 204. The rotating frame 301 and the threaded rod 108 are threadedly connected through the connecting ring 302. When sliding down, due to the transmission characteristics of the thread, the rotating frame 301 will rotate accordingly, and the rotation of the rotating frame 301 is transmitted through the fixed shaft 305, so that the connecting frame 307 also rotates.
