Anti-tip switch

Abstract

This anti-tipping switch belongs to the field of electrical switch technology, specifically relating to switches for equipment safety protection. It addresses the problems of existing anti-tipping switches, such as poor contact of conductive components during equipment vibration, delayed power cut-off upon tipping, poor housing protection leading to impurities, and easy damage to conductive connections. The technical solution includes: a bottom and top shell integrally formed and fixed with bolts; fixing blocks with mounting holes on both sides of the bottom shell; a conductive plate rotating via a mounting shaft inside the bottom shell; the conductive plate connected to an insulating sleeve, tension spring, and permanent magnet; a hemispherical inner wall with a slope and an internal gravity ball; a sliding rod passing through a partition and a spring between it and the pressure plate; and a second contact plate connected to the conductive plate via a flexible wire. It can be vertically fixed to the equipment. During vibration, the spring buffers the impact, and the permanent magnet stabilizes the conductive plate. When tipping, the gravity ball rolls, causing the sliding rod to lose pressure, and the tension spring pulls the conductive plate away from the first contact plate, cutting off the power. It is mainly used for equipment safety protection, achieving circuit stability during vibration and rapid power cut-off upon tipping.

Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, and in particular to an anti-tipping switch. Background Technology

[0002] Many electrical devices, if accidentally tipped over during use, could potentially cause safety hazards if left powered on. Therefore, anti-tip switches are necessary. These switches automatically cut off the circuit when the device tipps over, ensuring safety. These anti-tip switches are commonly used in household appliances and small industrial control equipment, serving as crucial components in equipment safety protection systems to reduce the safety risks associated with continued power supply after the device has tipped over.

[0003] Currently available anti-tipping switches have some shortcomings. When the equipment is working, vibration can easily affect the conductive contact parts inside the switch, leading to poor contact and causing equipment interruption or malfunction. Therefore, an anti-tipping switch is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where vibrations during equipment operation can cause poor contact in the conductive contact components inside the switch. This invention provides an anti-tipping switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-tipping switch includes a pair of bottom shells and a top shell, which are integrally formed and connected, and the pair of bottom shells and top shells are fixed together by bolts to form a housing; A first contact piece is fixed through one side of the bottom shell. An installation shaft is fixedly connected to the inner wall of one side of the bottom shell. A conductive plate is rotatably connected to the installation shaft. An insulating sleeve is fixed to one end of the conductive plate. A tension spring is installed between the insulating sleeve and the bottom inner wall of the bottom shell through a hook. An installation plate is fixedly connected to the inner wall of one side of the bottom shell. Permanent magnets are fixed to the bottom of the installation plate and the top of the insulating sleeve. The opposite ends of the two permanent magnets attract each other. A partition is integrally formed at the connection between the bottom shell and the top shell. A through slide rod is slidably connected to the bottom of the partition. The bottom of the slide rod abuts against the surface of the conductive plate. A pressure plate is provided at the top of the slide rod. A spring is installed between the pressure plate and the top of the slide rod through a spring seat. A gravity ball is provided inside the top shell. The gravity ball can move inside the top shell.

[0006] Furthermore, a second contact piece is fixedly connected to the bottom of the base shell, and the second contact piece is electrically connected to the conductive plate via a flexible wire.

[0007] Furthermore, the bottom inner wall of the top shell is provided with an inclined slope to guide the gravity ball.

[0008] Furthermore, fixing blocks are fixedly connected to both outer walls of the bottom shell, and each fixing block has a through mounting hole on one side.

[0009] Furthermore, the inner wall of the top shell is a concave hemispherical shape.

[0010] Furthermore, the slide bar is made of polytetrafluoroethylene.

[0011] In this application, during use, the product is vertically fixed to the equipment by passing self-tapping screws through the mounting holes of the fixing block. The first and second contact pieces are then connected to the equipment's wires or terminals. During normal operation, the gravity ball rolls along the hemispherical inner wall and slope of the top shell under its own weight to the top of the pressure plate. The weight of the gravity ball exerts downward pressure on the pressure plate, which transmits this pressure to the spring. The spring, under compression, pushes the sliding rod downwards. The bottom of the sliding rod exerts a downward thrust on the surface of the conductive plate, pressing one end of the conductive plate down. This causes the conductive plate to rotate around the mounting axis until it comes into close contact with the first contact piece. At this point, current is transferred from the first contact piece to the conductive plate, and then through the flexible wire to the second contact piece, thus connecting the equipment's circuit and ensuring normal operation. When the equipment vibrates during use, the vibration will cause the anti-tipping switch to vibrate as well, resulting in the gravity ball vibrating inside the top shell. At this time, the spring will expand and contract accordingly with the vibration of the gravity ball. Under the elastic action of the spring, it can buffer the vibration, absorb some of the vibration energy, and reduce the impact of vibration on the slide rod and conductive plate. At the same time, the two permanent magnets at the bottom of the mounting plate and the top of the insulating sleeve attract each other, and the resulting attraction can keep the conductive plate in a stable position, allowing the conductive plate to maintain continuous contact with the first contact piece. This effectively prevents poor contact caused by the vibration of the equipment and the gravity ball, ensuring that the circuit is always in a continuous state and the equipment can operate normally. When the equipment tilts, the tilt causes the anti-tipping switch to tilt as well. Under its own weight, the gravity ball inside the top shell rolls along the hemispherical inner wall and slope of the top shell to a position away from the pressure plate. At this time, the pressure plate at the top of the slide rod loses the pressure of the gravity ball. Under its own tension, the tension spring pulls the insulating sleeve at one end of the conductive plate through the hook. The insulating sleeve causes the conductive plate to rotate in the opposite direction around the mounting shaft. During this process, the distance between the two permanent magnets gradually increases, and the mutual attraction weakens until it disappears. Finally, the two permanent magnets separate, and the conductive plate gradually separates from the first contact piece as it rotates. The current can no longer be transmitted from the first contact piece to the second contact piece, and the circuit of the equipment is cut off, realizing power failure and preventing the equipment from continuing to work after tilting, which could cause a safety accident.

[0012] Beneficial effects: In this utility model, the anti-tipping switch has a spring between the slide rod and the pressure plate inside the top shell. When the equipment vibrates and causes the gravity ball to sway, the spring can extend and retract to buffer and absorb the vibration energy, reducing the impact on the stability of the slide rod under pressure. At the same time, the two permanent magnets inside the bottom shell attract each other, stabilizing the position of the conductive plate and ensuring that it remains in close contact with the first contact piece during vibration, avoiding poor circuit contact, ensuring normal operation of the equipment during vibration, and reducing the probability of failure. In this utility model, the anti-tipping switch, by setting a fixing block to be fixedly connected to the side of the housing, makes it easy to connect and fix the product to the equipment; This invention can avoid poor circuit contact, ensure normal operation of equipment under vibration, reduce the probability of failure, and facilitate connection and fixation with equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figures 1-4An anti-tipping switch includes: a pair of bottom shells 1 and top shells 2, which are manufactured using an integral molding process. After molding, the two shells are internally interconnected. The pair of bottom shells 1 and top shells 2 are fixedly connected by multiple sets of bolts, which are evenly distributed at the edges of the bottom shells 1 and top shells 2. Tightening the bolts forms a complete switch housing, which protects all internal components and prevents external dust, moisture, and other impurities from entering and affecting the operation of the components. Fixing blocks 3 are fixedly connected to the outer walls of both sides of the bottom shell 1. Each fixing block 3 is connected to the bottom shell 1 by welding or integral molding to ensure connection strength. Each fixing block 3 has a through mounting hole on one side, the diameter of which matches the diameter of commonly used self-tapping screws. During use, the entire anti-tipping switch can be vertically fixed to the equipment to be protected by passing the self-tapping screw through these mounting holes. After fixing, the switch will not shift due to slight shaking of the equipment.

[0017] A first contact piece 6 is fixed to one side of the bottom shell 1. The first contact piece 6 is conductive, with one end extending to the outside of the bottom shell 1 for connection with external wires or terminals, and the other end located inside the bottom shell 1 for cooperation with the subsequent conductive plate 5 to achieve circuit switching. The connection between the first contact piece 6 and the bottom shell 1 is insulated and sealed to prevent leakage. A mounting shaft 4 is fixedly connected to the inner wall of one side of the bottom shell 1. The conductive plate 5 can rotate flexibly around the mounting shaft 4 and is also conductive. An insulating sleeve is fixed to one end of the conductive plate 5. The insulating sleeve is made of insulating material such as plastic or rubber. A tension spring 15 is installed between the insulating sleeve and the bottom inner wall of the bottom shell 1 via hooks. The two ends of the tension spring 15 are respectively hooked on the insulating sleeve and the bottom inner wall of the bottom shell 1, and the hooks are fixedly connected to the corresponding components. A mounting plate 13 is also fixedly connected to one inner wall of the bottom shell 1. The mounting plate 13 is made of plastic and is fixed to the inner wall of the bottom shell 1 by screws. Permanent magnets 14 are fixed to the bottom of the mounting plate 13 and the top of the insulating sleeve. The permanent magnets 14 are fixed by adhesive or inlay. The opposite ends of the two permanent magnets 14 attract each other. In a natural state, they can pull the insulating sleeve upward by attraction, thereby playing a preliminary role in fixing the position of the conductive plate 5.

[0018] In another embodiment: Reference Figures 1-4An anti-tipping switch is provided, wherein a partition 7 is integrally formed at the connection between the bottom shell 1 and the top shell 2. The partition 7 is made of the same material as the bottom shell 1 and the top shell 2. After forming, it can divide the internal space of the bottom shell 1 and the top shell 2 to a certain extent. At the same time, a sliding hole is provided at the bottom of the partition 7. A sliding rod 8 passes through the sliding hole and is slidably connected to the partition 7. The sliding rod 8 is made of polytetrafluoroethylene. This material not only has good insulation performance, but also has good wear resistance, which can ensure that the sliding rod 8 can slide in the sliding hole for a long time without being easily worn. The bottom of the slide rod 8 extends into the interior of the bottom shell 1 and abuts against the surface of the conductive plate 5. The abutment position is located on the side of the conductive plate 5 away from the mounting shaft 4. The top of the slide rod 8 extends into the interior of the top shell 2. A pressure plate 10 is provided on the top of the slide rod 8. The pressure plate 10 is a circular plastic sheet. A spring 9 is installed between the pressure plate 10 and the top of the slide rod 8 through a spring seat. The spring seats are fixed to the bottom of the pressure plate 10 and the top of the slide rod 8 respectively. The two ends of the spring 9 are sleeved on the spring seats. In its natural state, the spring 9 can support the pressure plate 10. The inner wall of the top shell 2 is a concave hemispherical shape, which provides sufficient space for the gravity ball 12 to move and facilitates its rolling inside. The bottom inner wall of the top shell 2 is provided with an inclined slope 11, which slopes from the edge of the top shell 2 toward the pressure plate 10 to guide the rolling direction of the gravity ball 12. The gravity ball 12 inside the top shell 2 is a solid sphere and can move freely inside the top shell 2. When the equipment vibrates during use, the gravity ball 12 vibrates, and under the action of the spring 9, it can buffer and absorb part of the vibration. At the same time, the two permanent magnets 14 work together to keep the conductive plate 5 in stable contact with the first contact plate 6, preventing poor contact caused by the vibration of the equipment and the gravity ball 12.

[0019] A second contact piece 16 is fixedly connected to the bottom of the bottom shell 1. The second contact piece 16 is also conductive, with one end extending to the outside of the bottom shell 1 for connection with external wires or terminals. The second contact piece 16 is electrically connected to the conductive plate 5 via a flexible wire. The flexible wire is made of multi-strand fine copper wire and wrapped with an insulating outer sheath. One end is welded to the end of the second contact piece 16 located inside the bottom shell 1, and the other end is welded to the surface of the conductive plate 5. The flexible wire is long enough to freely extend and retract with the rotation of the conductive plate 5 and will not be broken due to the rotation of the conductive plate 5, ensuring that the second contact piece 16 and the conductive plate 5 always maintain a stable electrical connection. When the equipment is tilted, the gravity ball 12 rolls into the top shell 2, and the slide bar 8 is no longer pressed. At this time, the tension spring 15 pulls the conductive plate 5, causing the two permanent magnets 14 to separate. At the same time, the conductive plate 5 and the first contact piece 6 separate, realizing the power outage.
