Description

Technical Field

[0001] The utility model relates to the technical field of mouse guards, in particular to an installation structure of a mouse guard that is convenient for disassembly and assembly. Background Art

[0002] A mouse guard is a facility mainly used to prevent mice from entering specific places. It is usually made of materials such as aluminum alloy and stainless steel, and is mainly applied near power equipment such as substations, power and telecommunications machine rooms, and distribution transformers. The threat of mice to power facilities cannot be underestimated. They often crawl on substations, power and telecommunications machine rooms, and distribution transformers, causing phase-to-phase short circuits between the porcelain bushings and terminal posts of the transformers. This not only burns out the equipment, but also often causes the substation to trip, expanding power outages, posing a great threat to the safe operation of the power system. The mouse guard effectively prevents mice from entering key areas through physical barriers, reduces equipment damage, and avoids power outage accidents, thereby ensuring the safe and stable operation of the power system.

[0003] Chinese Patent with Publication No. CN220734195U discloses a sinking installation type mouse guard, which solves the problem that most current mouse guards are of the traditional plug-in type and require manual plugging and unplugging of the mouse guard, making it particularly inconvenient and labor-consuming to use, and achieves the effect of automatically lifting and lowering the mouse guard when powered on and manually lifting the mouse guard with less effort when powered off.

[0004] In the above patent, it is necessary to dig a groove under the ground at the door frame and then install the mouse guard inside the groove, which has the problem of difficult disassembly and assembly of the mouse guard; therefore, it does not meet the existing requirements, and for this reason, an installation structure of a mouse guard that is convenient for disassembly and assembly is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation structure of a mouse guard that is convenient for disassembly and assembly. By installing a rotating shaft at the lower end of the mouse guard, installing a fixing plate at the lower end of the door frame, and installing a positioning seat inside the door frame, the rotating shaft and the fixing plate are connected by bearings. Personnel push the mouse guard to rotate around the rotating shaft until the spherical convex block on the side of the mouse guard inserts into the inside of the positioning seat, thereby fixing the mouse guard on the door frame, and further achieving the purpose of preventing mice from entering key areas, and can solve the problems in the prior art.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A rat guard installation structure that is convenient for disassembly and assembly, including a door frame, and further including a rat guard body. The rat guard body is located on the side of the door frame. A weight block is provided at the upper end of the rat guard body, a rotating shaft is provided at the lower end of the rat guard body, a warning sign and a spherical bump are provided on the side of the rat guard body. Both ends of the rotating shaft are provided with fixing plates. An eccentric wheel is provided on one side of the fixing plate, a limiting plate is provided inside the fixing plate, a spring and a dial are provided inside the limiting plate. The ground is provided below the door frame, a limiting space is provided inside the door frame, and a positioning seat is provided inside the limiting space.

[0007] Preferably, a push rod is provided above the weight block, a socket is provided below the weight block, the lower end of the push rod extends into the socket, and a reminder sign is provided at the upper end of the push rod.

[0008] Preferably, the dial is axially connected to the limiting plate. The upper end of the dial is connected to one end of the spring, the lower end of the dial contacts the eccentric wheel, and the other end of the spring is connected to the limiting plate.

[0009] Preferably, the limiting plate is a steel plate structure, the fixing plate is a hollow cuboid structure, and the side of the fixing plate is in an open state.

[0010] Preferably, a limiting ring is provided on one side of the positioning seat, a clamping plate is provided on the other side of the positioning seat. The clamping plate is an arc-shaped structure, and a retaining ring is provided on the concave surface of the clamping plate.

[0011] Preferably, the limiting plate is connected to the fixing plate, the eccentric wheel is connected to the rotating shaft. A screw hole is provided on one side of the fixing plate, and a through hole is provided on the other side of the fixing plate.

[0012] Preferably, one end of the rotating shaft is located inside the through hole, the rotating shaft is connected to the fixing plate through a bearing, and the tip of the screw passes through the screw hole and extends into the door frame.

[0013] Preferably, at least two clamping plates are provided. The spherical bump is located between the two clamping plates, and the spherical end of the spherical bump passes through the retaining ring and extends into the positioning seat.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. In the present utility model, when a person pushes the push rod, the rat guard body rotates around the rotating shaft, and the spherical convex block on the side of the rat guard body inserts into the inside of the positioning seat, thereby fixing the rat guard body on the door frame, and further achieving the purpose of preventing rats from entering the critical area. When installing the rat guard body, directly connect the fixing plate to the door frame with screws, then connect the rotating shaft to the fixing plate using a bearing. Finally, set a cylindrical groove at a suitable position inside the door frame and install the positioning seat inside the groove to complete the installation. When disassembling the rat guard body, only need to remove the screws between the fixing plate and the door frame, and then the rat guard body can be removed, which is convenient for disassembling and assembling the rat guard body.

[0016] 2. In the present utility model, after the installation of the rat guard body is completed and the rat guard body needs to be lowered, when a person pushes the push rod, the rat guard body rotates. The spherical convex block on the rat guard body drives the positioning seat to move outside the limiting space, but the positioning seat cannot completely leave the inside of the limiting space due to the block of the limiting ring. As the force applied by the person to the push rod increases, the spherical convex block squeezes the two clamping plates, causing the two clamping plates to deform. At this time, the spherical convex block disengages from the outside of the positioning seat, and the rat guard body rotates and descends around the rotating shaft due to gravity. As the rat guard body descends, the eccentric wheel rotates, and the eccentricity of the contact between the eccentric wheel and the dial changes from small to large, causing the lower end of the dial to gradually move away from the rotating shaft. The spring thus elongates, and after the spring elongates, it generates a resilience force, thereby restricting the rotation speed of the eccentric wheel and making the rat guard body descend slowly, avoiding direct impact of the rat guard body with the ground and extending the service life of the rat guard body.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] To solve the problem of difficult disassembly and assembly of the rat guard, please refer to Figures 1-6 An embodiment provided by the present invention: A rat guard installation structure that is convenient for disassembly and assembly, including a door frame 2, and further including a rat guard body 1. The rat guard body 1 is located on the side of the door frame 2. A weight 102 is provided at the upper end of the rat guard body 1, a rotating shaft 104 is provided at the lower end of the rat guard body 1, a warning sign 101 and a spherical bump 106 are provided on the side of the rat guard body 1. Fixed plates 5 are provided at both ends of the rotating shaft 104. An eccentric wheel 105 is provided on one side of the fixed plate 5. A limiting plate 6 is provided inside the fixed plate 5. A spring 601 and a paddle 602 are provided inside the limiting plate 6. The ground 4 is provided below the door frame 2. A limiting space 201 is provided inside the door frame 2. A positioning seat 7 is provided inside the limiting space 201.

[0026] The limiting plate 6 is connected to the fixed plate 5. The eccentric wheel 105 is connected to the rotating shaft 104. A screw hole 501 is provided on one side of the fixed plate 5. A through hole 502 is provided on the other side of the fixed plate 5. One end of the rotating shaft 104 is located inside the through hole 502. The rotating shaft 104 is connected to the fixed plate 5 through a bearing. The tip of the screw passes through the screw hole 501 and extends into the door frame 2.

[0027] A person pushes the push rod 3, causing the rat guard body 1 to rotate around the rotating shaft 104 until the spherical bump 106 on the side of the rat guard body 1 inserts into the inside of the positioning seat 7, thereby fixing the rat guard body 1 on the door frame 2, and further achieving the purpose of preventing rats from entering the critical area. When installing the rat guard body 1, directly connect the fixing plate 5 to the door frame 2 with screws, then connect the rotating shaft 104 to the fixing plate 5 using a bearing. Finally, open a cylindrical groove at a suitable position inside the door frame 2 and install the positioning seat 7 inside the groove to complete the installation. When disassembling the rat guard body 1, only need to remove the screws between the fixing plate 5 and the door frame 2, and then the rat guard body 1 can be removed. At the same time, the groove opened on the door frame 2 will not affect the use of the door frame 2, which facilitates the disassembly and assembly of the rat guard body 1 and further improves the disassembly and assembly efficiency of the rat guard body 1.

[0028] Above the weight block 102 is provided with a push rod 3, below the weight block 102 is provided with a socket 103, the lower end of the push rod 3 extends into the inside of the socket 103, the upper end of the push rod 3 is provided with a reminder mark 301, the dial 602 is axially connected to the limiting plate 6, the upper end of the dial 602 is connected to one end of the spring 601, the lower end of the dial 602 contacts the eccentric wheel 105, the other end of the spring 601 is connected to the limiting plate 6, one side of the positioning seat 7 is provided with a limiting ring 701, the other side of the positioning seat 7 is provided with a clamping plate 702, the clamping plate 702 is of an arc structure, the concave surface of the clamping plate 702 is provided with a retaining ring 703, at least two clamping plates 702 are provided, the spherical bump 106 is located between the two clamping plates 702, and the spherical end of the spherical bump 106 passes through the retaining ring 703 and extends into the inside of the positioning seat 7.

[0029] When it is necessary to lower the rat guard body 1 after the installation of the rat guard body 1 is completed, a person pushes the push rod 3 to make the rat guard body 1 rotate. The spherical bump 106 on the rat guard body 1 drives the positioning seat 7 to move outside the limiting space 201 due to the restriction of the retaining ring 703, while the positioning seat 7 cannot completely leave the inside of the limiting space 201 due to the block of the limiting ring 701. As the force applied by the person to the push rod 3 increases, the spherical bump 106 squeezes the two clamping plates 702, causing the two clamping plates 702 to deform. At this time, the spherical bump 106 disengages from the outside of the positioning seat 7, and the rat guard body 1 rotates and descends around the rotating shaft 104 due to gravity. As the rat guard body 1 descends, the eccentric wheel 105 rotates, and the eccentricity of the contact between the eccentric wheel 105 and the dial 602 changes from small to large, causing the lower end of the dial 602 to gradually move away from the rotating shaft 104, and the spring 601 elongates accordingly. After the spring 601 elongates, it generates a resilience force, causing the dial 602 to squeeze the eccentric wheel 105, thereby restricting the rotation speed of the eccentric wheel 105 and making the rat guard body 1 descend slowly, avoiding the direct impact of the rat guard body 1 on the ground 4 and further extending the service life of the rat guard body 1.

[0030] Working principle: When the rat guard body 1 needs to be used, the operator pushes the push rod 3 so that the spherical bump 106 on the side of the rat guard body 1 is inserted into the inside of the positioning seat 7, thereby fixing the rat guard body 1 on the door frame 2, and further achieving the purpose of preventing rats from entering the critical area. When the rat guard body 1 needs to be lowered, the operator pushes the push rod 3. As the force applied by the operator to the push rod 3 increases, the spherical bump 106 disengages from the outside of the positioning seat 7. At this time, the rat guard body 1 rotates and descends around the rotating shaft 104 due to gravity, enabling the operator to control the rat guard body 1 only by manipulating the push rod 3, thus improving the practicality of the rat guard body 1.
