Technical Field
[0001] This utility model belongs to the technical field of rodent-proof devices, and in particular relates to a multifunctional telescopic rodent-proof device. Background Technology
[0002] Rodent control is a crucial aspect of power production sites. Rodents entering power distribution rooms can cause short circuits and power outages, resulting in significant economic losses. The main ways they cause damage include gnawing on cables or sneaking into transformers, causing short circuits or even fires. To prevent rodents from harming industrial sites, rodent barriers are necessary to prevent them from entering power supply areas.
[0003] For example, a Chinese invention patent (CN204217734U) describes a universal telescopic rodent-proof barrier, which includes a barrier body comprising a main barrier and a secondary barrier. The secondary barrier has a horizontal "U"-shaped structure and is fitted onto one end of the main barrier. A fixing plate is provided on one side of the horizontal "U"-shaped secondary barrier, and the fixing plate is fixedly welded to one side of the horizontal "U"-shaped secondary barrier. A fixing bolt hole is provided on the other side of the horizontal "U"-shaped secondary barrier, and a fastening bolt is installed in the fixing bolt hole. The main barrier and the secondary barrier are fixed together by the fastening bolt. After the main barrier of this utility model is stretched to a suitable size, it is firmly fixed to the inside of the secondary barrier by the fastening bolt, ensuring that the gap between the two is less than 0.5cm. However, during use, this device may not be able to control rodents entering between the door and the barrier, and the rodents may gnaw on the door, causing unnecessary losses. Furthermore, the fixing method is inconvenient for doors of different sizes, so certain improvements are needed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-3 This utility model provides a technical solution: a multi-functional telescopic rodent-proof device, including a rodent-proof box 1, an electric shock component 4 inside the rodent-proof box 1, a through hole 2 on one side inside the rodent-proof box 1, a door on one side of the rodent-proof box 1, and a fixing component 3 inside the through hole 2.
[0028] The electric shock assembly 4 includes a switch box 401, which is located on the side opposite the door. One side of the switch box 401 is fixedly connected to the bottom outer wall of the rodent-proof box 1. A support plate 402 is slidably connected inside the switch box 401. A trigger rod 403 is fixedly connected to the side of the support plate 402 away from the rodent-proof box 1. A spring 404 and a transmission rod 405 are fixedly connected to the other side of the support plate 402. The other end of the spring 404 is fixedly connected to the inner wall of the rodent-proof box 1. The other end of the transmission rod 405 extends into the interior of the rodent-proof box 1 and is fixedly connected to a connecting rod 407. A sleeve is fitted on the outer periphery of the connecting rod 407. The sleeve 406 and the connecting rod 407 have two symmetrically arranged spiral stroke grooves on their outer periphery. A stroke block is slidably connected inside the spiral stroke groove. The side of the stroke block away from the spiral stroke groove is fixedly connected to the inner wall of the sleeve 406. A first gear 408 is fixedly connected to the outer periphery of the sleeve 406. A second gear 409 is meshed on both sides of the first gear 408. A second rotating shaft 410 is fixedly connected inside the second gear 409. A second lead screw 411 is fixedly connected to the end of the second rotating shaft 410 away from the second gear 409. A conductive base plate 412 is provided at the other end of the second lead screw 411.
[0029] The specific implementation method is as follows: When the staff closes the door, the door causes the trigger rod 403 to move. The trigger rod 403 drives the transmission rod 405 and the connecting rod 407 to slide together through the support plate 402, and compresses the spring 404 during this process. The connecting rod 407 causes the sleeve 406 to rotate through the stroke block. Subsequently, the sleeve 406 drives the second gear 409 to rotate through the first gear 408. The second gear 409 drives the second lead screw 411 to rotate through the second rotating shaft 410, causing the conductive base plate 412 to slide, thereby pushing the conductor 413 to slide out of the rodent-proof box 1 to shock any rodents that accidentally enter. When the door is opened, the spring 404 rebounds, causing the transmission rod 405 and the connecting rod 407 to reset. At this time, the first gear 408 drives the second gear 409 to rotate in the opposite direction, causing the conductive base plate 412 to drive the conductor 413 to retract into the rodent-proof box 1, so that the conductor 413 is completely retracted into the rodent-proof box 1, ensuring the stability and safety of the device during use.
[0030] The trigger rod 403 is slidably connected inside the switch box 401. The transmission rod 405 is slidably connected between the switch box 401 and the rat-proof box 1. The connecting rod 407 and the second rotating shaft 410 are both provided with the same support plate 402 on their outer periphery. The connecting rod 407 and the support plate 402 are slidably connected. The second rotating shaft 410 is rotatably connected to the support plate 402 through the first bearing. The outer periphery of the sleeve 406 is rotatably connected to the second fixed seat through the fifth bearing. The bottom of the second fixed seat is fixedly connected to the bottom of the rat-proof box 1. The fixing component 3 includes a fixing block 301, which slides inside the through hole 2. Two first lead screws 302 are provided on the side of the fixing block 301 near the rat-proof box 1. The outer periphery of the first lead screw 302 is rotatably connected to the fixing plate through the fourth bearing. One side of the fixing plate is fixedly connected to the inside of the rat-proof box 1. The other end of the first lead screw 302 is fixedly connected to a first bevel gear 303. The end of the first bevel gear 303 away from the fixing block 301 is meshed with a second bevel gear 304. The gear 304 is internally fixedly connected to the same first rotating shaft 305. The top end of the first rotating shaft 305 extends to the outside of the rodent-blocking box 1 and is connected to a hand crank 306. The first rotating shaft 305 is rotatably connected to the rodent-blocking box 1 through a second bearing. The outer periphery of the first rotating shaft 305 is rotatably connected to a first fixed seat through a third bearing. The first fixed seat is located between two second bevel gears. One side of the first fixed seat is fixedly connected to the inner wall of the rodent-blocking box 1. The conductive base plate 412 is slidably connected to the inside of the rodent-blocking box 1. The conductive base plate 412 is connected to an external power source. Multiple conductors 413 are fixedly connected to the side of the conductive base plate 412 away from the second lead screw 411. The other end of the conductor 413 extends to the outside of the rodent-blocking box 1. The conductor 413 is slidably connected to the inside of the rodent-blocking box 1. Two first threaded sleeves are fixedly connected inside the conductive base plate 412. The first threaded sleeves are threadedly connected to the second lead screw 411. Two second threaded sleeves are fixedly connected inside the fixing block 301. The second threaded sleeves are threadedly connected to the first lead screw 302.
[0031] The specific implementation method is as follows: the operator rotates the hand crank 306 to drive the second bevel gear 304 to rotate through the first rotating shaft 305. The second bevel gear 304 meshes with the first bevel gear 303, causing the first bevel gear 303 to drive the first lead screw 302 to rotate. The first lead screw 302 drives the fixing block 301 to slide to the outside of the rodent barrier box 1, so that the fixing block 301 can fit tightly against the wall, thereby sealing the gap between the rodent barrier box 1 and the wall.
[0032] Working principle: When in use, the operator closes the door, which pushes the trigger rod 403 to move. The trigger rod 403 drives the transmission rod 405 and connecting rod 407 to slide and compress the spring 404 through the support plate 402. The connecting rod 407 drives the sleeve 406 to rotate through the stroke block. The sleeve 406 drives the second gear 409 to rotate through the first gear 408. The second gear 409 drives the second lead screw 411 to rotate through the second rotating shaft 410. The second lead screw 411 drives the conductive base plate 412 to slide, causing the conductor 413 to slide out to the outside of the rodent-proof box 1. When the door is opened, the second spring 404 drives the transmission rod 405 and connecting rod 407 to reset. The first gear 408 drives the second lead screw 411 to reverse through the second gear 409. The conductive base plate 412 drives the conductor 413 to retract into the rodent-proof box 1, so that the conductor 413 is retracted into the rodent-proof box 1.
[0033] The staff rotates the hand crank 306, which drives the second bevel gear 304 to rotate through the first rotating shaft 305. The second bevel gear 304 drives the first lead screw 302 to rotate through meshing with the first bevel gear 303. The first lead screw 302 drives the fixing block 301 to slide outward of the rodent barrier box 1 through the second threaded sleeve, thereby sealing the gap between the rodent barrier box 1 and the wall.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
