Linkage limiting protection mechanism and mousetrap

Abstract

The utility model discloses a linkage limiting protection mechanism and a mousetrap. The linkage limiting protection mechanism comprises a tooth set part, a limiting mechanism and an abutting part, wherein the abutting part abuts against the limiting mechanism or releases the abutting to correspondingly enable the limiting mechanism not to limit rotation of the tooth set part or limit rotation of the tooth set part. When the abutting part abuts against the limiting mechanism, the limiting mechanism and the tooth set component are in an independent operation state. The limiting state of the limiting mechanism on the tooth set component is controlled through the abutting part, and the structure is simple and easy to achieve; after the abutting part is moved out, the tooth set component is limited by the limiting mechanism, so that rotation of the rotating plate driven by the tooth set component is limited during disassembly and maintenance, and the effects of protecting an operator and conveniently and smoothly disassembling a specific component are achieved.

Description

Technical Field

[0001] The utility model belongs to the technical field of limiting mechanisms, and in particular relates to a linkage limiting protection mechanism and a mousetrap. Background Art

[0002] A mousetrap is a device that traps mice after they enter and restricts their movement space. Currently, a rotating plate is used to rotate, so that mice on the rotating plate are brought into the space below for capture. A detection device is set on one side of the rotating plate to detect the entry of mice. After the detection device detects the entry of mice, it controls the rotation of the rotating plate. Because the rotating plate rotates in one direction, it is difficult for captured mice to escape through the rotating plate to the outside. The rotating plate is divided into multiple parts by blade-shaped parts. After rotating a certain angle, the parts of the rotating plate re-cover the surface, re-forming a passage for mice to walk. When other mice enter again, the above rotation operation is repeated, thereby achieving the desired mouse-catching effect.

[0003] However, in current mousetraps, when the hand reaches close to the rotating plate and needs to be disassembled to check the capture status or inspect a certain component without turning off the power, the detection device will be triggered to control the rotating plate to rotate. At this time, the rotating plate will touch the operator's hand, which may easily cause injury and hinder the disassembly operation. In view of this, it is necessary to develop a linkage limit protection mechanism and a mousetrap. Utility Model Content

[0004] The purpose of the utility model is to provide a linkage limit protection mechanism and a mousetrap to solve the above-mentioned technical problems. The limiting mechanism controls the limiting state of the tooth group component by the abutment portion. This structure is simple and easy to implement. The limiting mechanism limits the tooth group component after the abutment portion is moved out, thereby limiting the rotation of the rotating plate driven by the tooth group component during disassembly and maintenance, thereby protecting the operating personnel and facilitating the smooth disassembly of specific components.

[0005] In order to achieve the above-mentioned purpose of the utility model, the technical solution adopted by the utility model is as follows:

[0006] A linkage limit protection mechanism includes a tooth assembly component, a limit mechanism, and an abutment portion;

[0007] The abutment portion abuts against the limiting mechanism so that the limiting mechanism does not restrict the rotation of the gear set component.

[0008] Alternatively, the abutment portion releases the interference with the limiting mechanism, causing the limiting mechanism to restrict the rotation of the gear assembly. When the abutment portion interferes with the limiting mechanism, the limiting mechanism and the gear assembly operate independently. Controlling the limiting state of the gear assembly by the limiting mechanism through the abutment portion is simple and easy to implement. By removing the abutment portion, the limiting mechanism restricts the gear assembly, thereby limiting the rotation of the rotating plate driven by the gear assembly during disassembly and maintenance, protecting workers and facilitating the smooth removal of specific components.

[0009] Preferably, the limiting mechanism includes a frame and a rotating block movably connected to the frame, wherein the abutment portion is provided so as to intersect with the movement path of one end of the rotating block; and the rotation path of the other end of the rotating block intersects with the rotation path of the gear assembly. The rotation path of the other end of the rotating block intersects with the surface rotation path of the gear. The rotating block is hingedly connected to the frame. One end of the frame intersects with the movement path of one end of the rotating block, and when the abutment portion is removed, one end of the rotating block contacts the inner surface of the frame. The rotating block, with the rotation center as the starting point, has an end away from the gear assembly having a smaller weight than the other end close to the gear assembly, causing the rotating block to rotate spontaneously in a non-interference state and contact the gear of the gear assembly, thereby limiting the rotation of the gear assembly. When the abutment portion contacts one end of the rotating block, the rotating block rotates about the rotation center, thereby moving the other end of the rotating block away from the gear assembly, releasing the restriction on the gear assembly. The frame and the rotating block are in a hinged state, so that the other end of the rotating block is away from the tooth group component. The movable paths at both ends of the rotating block intersect with the installation location of the abutment portion and the rotation path of the tooth group component respectively. One of the interfering states can be selected as needed to cross and replace the interfering state. For example, when it is necessary to release the restriction on the tooth group component, the abutment portion is installed at one end of the rotating block and interferes with one end of the rotating block, and the other end of the rotating block rotates accordingly to move away from the tooth group component; when it is necessary to restrict the rotation of the tooth group component, the abutment portion is removed, one end of the rotating block rotates and contacts the frame, and the other end of the rotating block turns back and rotates to the tooth group component to interfere with the tooth group component; the movable paths at both ends of the rotating block intersect with the installation location of the abutment portion and the tooth group component installation location respectively. By controlling the rotation state of the tooth group component by interfering at one end and releasing the interference at the other end, the rotation state of the rotating plate is controlled. This structure is simple, the linkage operation is easy to implement, and it can effectively protect the operating personnel.

[0010] Preferably, the abutment portion includes a contact post, which is arranged to intersect with the moving path of one end of the rotating block. The abutment portion is partially embedded in the frame, and the contact post is arranged to abut the rotating block, so as to facilitate the control of the rotation state of the gear assembly.

[0011] Preferably, the frame is provided with a notch, and the inner surface of the notch abuts against one end of the rotating block when the abutting portion is in a state of being separated from the rotating block;

[0012] The interference column is used to interfere with one end of the rotating block. Specifically, when the interference column is engaged in the notch, the interference column interferes with one end of the rotating block. A notch is provided, and when the interference column is removed, one end of the rotating block rotates to the notch, and one end of the rotating block partially extends out of the notch. When the other end of the rotating block interferes with the tooth assembly, it is beneficial to provide support for the rotating block; improve the stability of the limiting process; at the same time, when the interference column is installed, the interference column is installed in the notch, so that the rotating block and the notch are in a state of no conflict. This installation method requires less space and has a high degree of integration, which can effectively improve space utilization.

[0013] Preferably, the abutment portion further comprises a housing disposed above the abutment post, the lower surface of the housing being in contact with the upper surface of the frame. The housing being in contact with the frame, and the abutment post being disposed at the lower end of the housing facilitates the operator's removal of the abutment post. Furthermore, when the abutment post abuts one end of the rotating block, the housing has a certain weight, and the notch engages the abutment post, thereby improving the stability of the abutment process against the rotating block.

[0014] Preferably, the rotating block is provided with one or more protrusions on the side facing the frame. Providing one or more protrusions and multiple points of counterweighting can help improve the stability of the rotating block during rotation and allow the rotating block to spontaneously rotate to the gear rotation path when the rotating block and the interference column are not in conflict.

[0015] Preferably, the rotating block is provided with a reinforcement block at one end proximal to the gear assembly. Specifically, the reinforcement block is provided at one end proximal to the gear assembly. The reinforcement block effectively prevents collisions during rotation of the gear assembly, allowing the rotating block to effectively fit between the gear teeth, thereby securing the gear assembly and improving the stability of the gear assembly.

[0016] Preferably, the housing is provided with one or more slots, and the frame is provided with an interlocking block that engages with the slots. Providing corresponding slots and interlocking blocks improves the fit stability between the frame and the housing, thereby making the interference state between the interference column and one end of the rotating block more stable.

[0017] Preferably, the gear assembly includes a gear and a rotating plate in transmission connection with the gear. The gear is disposed within a frame, and the rotation path of the other end of the rotating block intersects the surface rotation path of the gear. The rotating block engages with the teeth of the gear, thereby limiting the rotation of the gear. This ensures that even when the detection device is controlling the rotation of the gear assembly, the rotation of the rotating plate is still limited, thereby protecting the operator.

[0018] A mousetrap comprising any of the above-mentioned linkage limiting protection mechanisms.

[0020] The utility model controls the limiting state of the tooth group component by the limiting mechanism through the abutment part. The structure is simple and easy to implement. The limiting mechanism limits the tooth group component after the abutment part is moved out, thereby limiting the rotation of the rotating plate driven by the tooth group component during disassembly and maintenance, thereby protecting the operating personnel and facilitating the smooth disassembly of specific components.

[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0033] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0034] Reference Figures 1 to 9 , a linkage limit protection mechanism includes a tooth group component 1, characterized in that it also includes a limit mechanism 2 and an abutment portion 3; the abutment portion 3 interferes with the limit mechanism 2, correspondingly causing the limit mechanism 2 to not restrict the rotation of the tooth group component 1, or the abutment portion 3 releases the interference with the limit mechanism 2, correspondingly causing the limit mechanism 2 to restrict the rotation of the tooth group component 1. When the abutment portion 3 interferes with the limit mechanism 2, the limit mechanism 2 and the tooth group component 1 are in an independent operation state. The limit state of the tooth group component 1 is controlled by the abutment portion 3. This structure is simple and easy to implement; the limit mechanism 2 restricts the tooth group component 1 by removing the abutment portion 3, thereby achieving the effect of limiting the rotation of the rotating plate driven by the tooth group component 1 during disassembly and maintenance, thereby protecting the operating personnel and facilitating the smooth disassembly of specific components.

[0035] The limiting mechanism 2 includes a frame 21 and a rotating block 22 movably connected to the frame 21. The abutment portion 3 is arranged to intersect with the movement path of one end of the rotating block 22; the rotation path of the other end of the rotating block 22 intersects with the rotation path of the gear assembly 1. The rotation path of the other end of the rotating block 22 intersects with the surface rotation path of the gear 11. The rotating block 22 is hinged to the frame 21. One end of the frame 21 intersects with the movement path of one end of the rotating block 22. When the abutment portion 3 is removed, one end of the rotating block 22 contacts the inner surface of the frame 21. The rotating block 22 takes the rotation center as the starting point, and the weight of the end away from the tooth group component 1 is less than the other end close to the tooth group component 1, so that the rotating block 22 rotates spontaneously when it is not in conflict with the interference part 3 and interferes with the gear 11 of the tooth group component 1, thereby limiting the rotation of the tooth group component 1; and when the interference part 3 interferes with one end of the rotating block 22, the rotating block 22 rotates around the rotation center, so that the other end of the rotating block 22 is away from the tooth group component 1, and the restriction on the tooth group component 1 is released. The frame 21 and the rotating block 22 are in a hinged state, so that the other end of the rotating block 22 is away from the tooth group component 1, and the movable paths at both ends of the rotating block 22 intersect with the installation location of the abutment portion 3 and the rotation path of the tooth group component 1 respectively. One of them is selected to cross and replace the interference state as needed. If it is necessary to release the restriction on the tooth group component 1, the abutment portion 3 is installed at one end of the rotating block 22 to interfere with one end of the rotating block 22, and the other end of the rotating block 22 rotates accordingly to move away from the tooth group component 1; if it is necessary to restrict the tooth group component 1 During rotation, the abutment part 3 is removed, one end of the rotating block 22 rotates and contacts the frame 21, and the other end of the rotating block 22 turns back and rotates to the tooth group component 1 to abut against the tooth group component 1; the movable paths at both ends of the rotating block 22 intersect with the installation location of the abutment part 3 and the location of the tooth group component 1 respectively, and the rotation state of the tooth group part 1 is controlled by abutting at one end and releasing the abutment at the other end, thereby controlling the rotation state of the rotating plate. This structure is simple, the linkage operation is easy to implement, and it can effectively protect the operators.

[0036] The abutment portion 3 includes a contact post 31, which is arranged to intersect the movement path of one end of the rotating block 22. The abutment portion 3 is partially embedded in the frame 21 and is provided with the contact post 31 that can abut the rotating block 22 to facilitate controlling the rotation state of the gear assembly 1.

[0037] The frame 21 is provided with a notch 211 , and the inner surface of the notch 211 contacts one end of the rotating block 22 when the abutting portion 3 and the rotating block 22 are separated.

[0038] The interference post 31 is used to interfere with one end of the rotating block 22. Specifically, when the interference post 31 is engaged in the notch 211, the interference post 31 interferes with one end of the rotating block 22. The notch 211 is provided. When the interference post 31 is removed, one end of the rotating block 22 rotates to the notch 211, and one end of the rotating block 22 partially extends outside the notch 211. When the other end of the rotating block 22 interferes with the tooth assembly component 1, it is beneficial to provide support for the rotating block 22 and improve the stability of the limiting process. At the same time, when the interference post 31 is installed, the interference post 31 is installed in the notch 211, so that the rotating block 22 and the notch 211 are in a state of no conflict. This installation method requires less space and has a high degree of integration, which can effectively improve space utilization.

[0039] The abutting portion 3 further includes a housing 32 disposed above the abutting post 31, with the lower surface of the housing 32 in contact with the upper surface of the frame 21. The housing 32 being in contact with the frame 21, with the abutting post 31 disposed at the lower end of the housing 32, facilitates the operator's removal of the abutting post 31. Furthermore, when the abutting post 31 abuts one end of the rotating block 22, the housing 32 has a certain weight, which, combined with the interlocking action of the notch 211 against the abutting post 31, improves the stability of the abutment process against the rotating block 22.

[0040] The rotating block 22 is provided with one or more protrusions 221 on the side facing the frame 21. Providing one or more protrusions 221 and multiple counterweights helps improve the stability of the rotating block 22 during rotation and allows the rotating block 22 to spontaneously rotate to the gear rotation path when the rotating block 22 and the interference post 31 are not in conflict.

[0041] The rotating block 22 is provided with a reinforcement block 222 at one end near the gear assembly 1. Specifically, the reinforcement block 222 is provided at the end near the gear 11. The reinforcement block 222 effectively prevents collisions during the rotation of the gear assembly 1, allowing the rotating block 22 to effectively fit between the teeth of the gear 11, thereby retaining the gear assembly 1 in position and improving the stability of the gear assembly's position.

[0042] The housing 32 is provided with one or more slots 321, and the frame 21 is provided with an engaging block 212 that engages with the slots 321. The corresponding slots 321 and engaging blocks 212 are provided to improve the fit stability between the frame 21 and the housing 32, thereby making the interference state between the interference post 31 and one end of the rotating block 22 more stable.

[0043] The gear assembly 1 includes a gear 11 and a rotating plate 12 drivingly connected to the gear 11. The gear 11 is disposed within a frame 21. The rotation path of the other end of the rotating block 22 intersects the surface rotation path of the gear 11. By embedding the rotating block 22 in the teeth of the gear 11, the rotation of the gear 11 is restricted. This ensures that even when the detection device is controlling the rotation of the gear assembly, the rotation of the rotating plate 12 is restricted, thus protecting the operator.

[0044] The part of the gear assembly 1 that can be restricted from rotating is the gear 11 . The gear 11 is disposed in the frame 21 and on the same side as the rotating block 22 . The gear 11 is movably connected to the frame 21 .
