Description

Technical Field

[0001] This utility model relates to the field of safety switch structures, specifically to a safety switch structure. Background Technology

[0002] As home appliances become increasingly complex, users are placing higher demands on their safety, especially in frequently used appliances like washing machines, where safety switches play a crucial role. Washing machine safety switches typically include a lever on the lid that controls the on / off state of the circuit, and a vibration protection safety lever. When the washing machine is washing or spinning, unevenly distributed clothes can cause the tub to vibrate violently, affecting washing performance and potentially damaging the machine. In this situation, the vibration protection safety lever detects the tub's vibration and cuts off the motor power, stopping the tub and preventing potential damage.

[0003] However, because the control circuit on / off lever and the vibration protection safety lever are usually arranged in the same direction, this results in wasted internal space in the washing machine, increasing its overall size and requiring more space for placement and installation. Furthermore, the arrangement of parts in the same direction can also lead to difficulties in maintenance and replacement. When maintenance or replacement of the safety switch is needed, the dense layout of parts may require technicians to spend more time and effort disassembling and reinstalling them, which not only reduces maintenance efficiency but also increases maintenance costs. Summary of the Invention

[0004] One of the objectives of this invention is to provide a safety switch structure to solve the problems of space waste and maintenance difficulties caused by the arrangement of parts in the same direction in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A safety switch structure includes:

[0007] A first spring, a second spring, and a housing, wherein the first and second springs are mounted inside the housing, and at least a portion of the projection of the second spring onto the plane of the first spring intersects with the first spring; a first swing assembly and a first rotating shaft, wherein one end of the first swing assembly is located outside the housing, and the other end is oscillatingly mounted inside the housing via the first rotating shaft, and oscillating at one end of the first swing assembly can drive the other end to swing in the same direction; the other end of the first swing assembly corresponds to the first and second springs, and the first swing assembly is configured such that during the oscillation of the other end, the first spring and the second spring at the point where their projections intersect can come into contact or be separated; a second swing assembly and a second rotating shaft, wherein one end of the second swing assembly is located outside the housing, and the other end is oscillatingly mounted inside the housing via the second rotating shaft, and oscillating at one end of the second swing assembly can drive the other end to swing in the same direction; the other end of the second swing assembly corresponds to the second spring at the point where their projections intersect, and the second swing assembly is configured such that during the oscillation of the other end, the first spring and the second spring at the point where their projections intersect can be separated; the first rotating shaft and the second rotating shaft are perpendicular to each other.

[0008] According to the above technical means, the first rotating shaft and the second rotating shaft are arranged perpendicularly to each other, which effectively reduces the density of components in a single direction and avoids the clustering of components in the same direction, thereby achieving efficient use of space resources as a whole and greatly saving the space occupied inside the equipment; the projection of part of the second spring on the plane where the first spring is located intersects with the first spring, which allows the first spring and the second spring to contact or separate each other during the contact process, thereby enabling the equipment to operate normally or stop operating; the first swing arm assembly swings along the first rotating shaft, causing the first spring and the second spring to contact each other, and the equipment to operate normally, and causing the first spring and the second spring to separate, and the equipment to stop operating, ensuring the safety of the equipment during operation; the housing can prevent the first spring and the second spring from misaligning during contact or separation and protect the first spring and the second spring; during the swing of the second swing assembly along the second rotating shaft, it can separate the first spring and the second spring at the intersection of the projections, and the equipment stops operating.

[0009] Furthermore, one end of the first swing component has a first terminal and a second terminal. The first terminal and the second terminal have a "Y" shaped structure and are arranged back and forth along the swing direction. During the swing, the first terminal can abut against the intersection of the first spring and the projection, so that the second spring at the intersection of the first spring and the projection comes into contact. During the swing, the second terminal can abut against the intersection of the second spring and the projection, so that the first spring at the intersection of the second spring and the projection is separated.

[0010] According to the above technical means, the first swing component has a first terminal. During the swinging process, the first terminal can abut against the intersection of the first spring and the projection, so that the first spring and the second spring abut against each other, thereby enabling the equipment to operate normally. During the swinging process, the second terminal can abut against the intersection of the second spring and the projection, so that the first spring and the second spring are separated, thereby enabling the equipment to stop operating. The operation or shutdown of the equipment can be precisely controlled, thereby ensuring the safety of the equipment during operation.

[0011] Furthermore, it also includes a torsion spring, which is sleeved on the first rotating shaft, with one end pin abutting against the other end of the first swing assembly and the other end pin abutting against the second swing assembly.

[0012] According to the above technical means, the torsion spring is sleeved on the first rotating shaft to prevent the torsion spring from being misaligned during compression or restoration. One end pin of the torsion spring abuts against the other end of the first swing component, and the other end pin abuts against the second swing component, so that the first swing component can compress the torsion spring during swinging, and the torsion spring can cause the first swing component to swing during the reset process, so as to separate the first spring and the second spring, thereby stopping the equipment from operating.

[0013] Furthermore, the second swing assembly includes a connector and a swing rod. One end of the connector is swingably mounted inside the housing via the second pivot, and the other end is connected to the swing rod.

[0014] According to the above-mentioned technical means, the connector and the swing arm are connected to form the second swing assembly, which makes the second swing assembly easy to assemble and disassemble, reducing maintenance costs; one end of the connector is installed in the housing, thereby protecting the connector located in the housing from damage.

[0015] Furthermore, a first snap-fit ​​element is formed at the other end of the connector, and a second snap-fit ​​element is formed at one end of the swing arm. The first snap-fit ​​element and the second snap-fit ​​element can be snapped into or unsnapped, so that the connector and the swing arm can be snapped into or unsnapped.

[0016] According to the above technical means, the first snap-fit ​​component and the second snap-fit ​​component can snap into or unsnap into each other, so that the connector and the swing arm can snap into or unsnap into each other, thereby making the snap-fit ​​method of the connector and the swing arm more convenient for the disassembly and maintenance of the second swing assembly and reducing maintenance costs.

[0017] Furthermore, a third terminal is formed on the connector, which can abut against the second spring piece at the projection intersection portion during the swinging process of the connector, so as to separate the first spring piece and the second spring piece at the projection intersection portion.

[0018] According to the above-mentioned technical means, during the swinging process of the third terminal along the second rotation axis, the first spring and the second spring at the intersection of the projection can be separated, the equipment stops running, and the safety of the equipment during operation is ensured.

[0019] Furthermore, it also includes a spring, one end of which is connected to the housing and the other end of which is connected to the connector. When the third terminal abuts against the second spring piece at the intersecting projection portion, the connector can compress the spring to give the connector a tendency to return to its original position.

[0020] According to the above technical means, the connector can compress the spring so that the connector has a reset tendency. When the connector swings along the second rotating shaft, the spring will reset, thereby separating the first spring piece and the second spring piece. At this time, the equipment stops running, thus ensuring the safe operation of the equipment.

[0021] Furthermore, the connector forms a limiting member, and the spring is sleeved on the limiting member.

[0022] According to the above-mentioned technical means, the spring is sleeved on the outer periphery of the limiting member to prevent the spring from misaligning with the limiting member during compression and reset, thereby preventing damage to the device or personal injury during use.

[0023] Furthermore, the housing includes a first sub-housing and a second sub-housing, which are connected to form a cavity. The first sub-housing abuts against the first spring and the second spring, respectively, so that the intersecting portions of the projections of the first spring and the second spring are installed in the cavity.

[0024] According to the above technical means, the first sub-shell and the second sub-shell are connected to form the shell, making the shell easy to install and disassemble. The first spring and the second spring abut against the first shell, and the first spring and the second spring are installed inside the shell, making the installation of the first spring and the second spring more stable and preventing the first spring and the second spring from being misaligned, thereby causing damage to the device.

[0025] Furthermore, a third snap-fit ​​member is formed on the first sub-shell, and a fourth snap-fit ​​member is formed on the second sub-shell. The third snap-fit ​​member can engage or disengage with the fourth snap-fit ​​member, so that the first sub-shell and the second sub-shell can engage or disengage.

[0026] According to the above-mentioned technical means, the third snap-fit ​​component can be snapped into or unsnap with the fourth snap-fit ​​component, and the snap-fit ​​connection method facilitates the replacement and maintenance of the housing, reducing the maintenance cost and difficulty of the housing.

[0027] The beneficial effects of this utility model are:

[0028] During the swing of the second swing assembly along the second rotation axis, the first spring and the second spring at the intersection of their projections are separated, and the device stops operating. The first and second rotation axes are arranged perpendicularly to each other, effectively reducing the density of components in a single direction and avoiding the clustering of components in the same direction, thereby achieving efficient use of space resources and greatly saving internal space. The projection of a portion of the second spring on the plane of the first spring intersects with the first spring, allowing the first and second springs to contact or separate during contact, thus enabling the device to operate normally or stop. The swing of the first swing arm assembly along the first rotation axis causes the first and second springs to contact each other, enabling the device to operate normally, and causes the first and second springs to separate, stopping the device and ensuring safety during operation. The housing prevents misalignment of the first and second springs during contact or separation and protects the first and second springs. Attached Figure Description

[0040] like Figures 1-3 As shown, this utility model proposes a safety switch structure, including:

[0041] A first spring 1, a second spring 2, and a housing 3 are provided. The first spring 1 and the second spring 2 are installed inside the housing 3, and at least a portion of the projection of the second spring 2 onto the plane of the first spring 1 intersects with the first spring 1. A first swing assembly 4 and a first rotating shaft 5 are provided. One end of the first swing assembly 4 is located outside the housing 3, and the other end is swayably installed inside the housing 3 via the first rotating shaft 5. The swinging of one end of the first swing assembly 4 can drive the other end to swing in the same direction. The other end of the first swing assembly 4 corresponds to the first spring 1 and the second spring 2. The first swing assembly 4 is configured to be able to swing during the swinging of the other end. The first spring 1 and the second spring 2 at the intersection of the projections are brought into contact or separated; a second swing assembly 6 and a second rotating shaft 7 are present, one end of the second swing assembly 6 is located outside the housing 3, and the other end is oscillatingly mounted inside the housing 3 via the second rotating shaft 7.

[0042] like Figures 1-3 As shown, when the equipment cover is closed, one end of the first swing component 4 swings around the first rotating shaft 7, causing the other end of the first swing component 4 to swing in the same direction. During this swing, the other end of the first swing component 4 abuts against the first spring piece 1, causing the first spring piece 1 to contact the second spring piece 2 at the intersection of the projection, thus enabling the equipment to operate normally. When the equipment cover is opened, one end of the first swing component 4 swings around the first rotating shaft 5, causing the other end of the first swing component 4 to swing in the same direction. During this swing, the other end of the first swing component 4 abuts against the second spring piece 2, causing the first spring piece 1 to separate from the second spring piece 2 at the intersection of the projection, thus enabling the equipment to stop operating. When the equipment cover is closed, if the rotating equipment exceeds its rotation range, the rotating equipment will strike one end of the second swing component 6, causing one end of the second swing component 6 to drive the other end of the second swing component 6 to swing around the second rotating shaft 7. During the swing of the other end of the second swing component 6, the first spring piece 1 and the second spring piece 2 at the intersection of the projection are separated.

[0043] Preferably, the first spring 1 and the second spring 2 are made of metal, while the housing 3, the second swing assembly 6, the first swing assembly 4, the first rotating shaft 5 and the second rotating shaft 7 are made of plastic, which can reduce costs.

[0044] The first rotating shaft 5 and the second rotating shaft 7 are arranged perpendicularly to each other, which effectively reduces the density of components in a single direction and avoids the clustering of components in the same direction, thereby achieving efficient use of space resources as a whole and greatly saving the space occupied inside the equipment. The projection of part of the second spring 2 on the plane where the first spring 1 is located intersects with the first spring 1, which allows the first spring 1 and the second spring 2 to contact or separate each other during the contact process, thereby enabling the equipment to operate normally or stop operating. The first swing arm assembly swings along the first rotation axis, which allows the first spring 1 and the second spring 2 to contact each other, enabling the equipment to operate normally, and separates the first spring 1 and the second spring 2, ensuring the safety of the equipment during operation. The housing 3 can prevent the first spring 1 and the second spring 2 from misaligning during contact or separation and protect the first spring 1 and the second spring 2. During the swing of the second swing assembly 6 along the second rotation axis, it can separate the first spring 1 and the second spring 2 whose projections intersect, and the equipment stops operating.

During the swing, the second terminal 42 can abut against the second spring 2 and the projection intersection part, so that the second spring 2 and the first spring 1 of the projection intersection part are separated.

[0046] The first swing assembly 4 has a first terminal 41. During the swinging process, the first terminal 41 can abut against the first spring 1 and the projection intersection, so that the first spring 1 and the second spring 2 abut against each other, thereby enabling the equipment to operate normally. During the swinging process, the second terminal 42 can abut against the second spring 2 and the projection intersection, so that the first spring 1 and the second spring 2 are separated, thereby enabling the equipment to stop operating. It can accurately control the operation or shutdown of the equipment, thereby ensuring the safety of the equipment during operation.

[0047] like Figures 1-3 As shown, in this embodiment, a torsion spring 8 is also included. The torsion spring 8 is sleeved on the first rotating shaft 5. One end of the torsion spring 8 abuts against the other end of the first swing component 4, and the other end abuts against the second swing component 6.

[0048] Preferably, the torsion spring 8 can be replaced with other elastic elements capable of resetting.

[0049] The torsion spring 8 is sleeved on the first rotating shaft 5 to prevent the torsion spring 8 from being misaligned during compression or restoration.

[0053] like Figures 1-3 As shown, this embodiment also includes a spring 9. One end of the spring 9 is connected to the housing 3, and the other end is connected to the connector 61. During the process of the third terminal 612 abutting against the second spring piece 2 at the intersection of the projections, the connector 61 can compress the spring 9, so that the connector 61 has a tendency to return to its original position. The connector 61 can compress the spring 9, so that the connector 61 has a tendency to return to its original position. During the swinging of the connector 61 along the second rotating shaft 7, the spring 9 will return to its original position, thereby separating the first spring piece 1 and the second spring piece 2. At this time, the equipment stops operating, thus ensuring the safe operation of the equipment.

The first sub-housing 31 abuts against the first spring 1 and the second spring 2, respectively, so that the intersecting portions of the projections of the first spring 1 and the second spring 2 are installed in the cavity. The connection between the first sub-housing 31 and the second housing 32 forms the housing 3, making the housing 3 easy to install and disassemble. The first spring 1 and the second spring 2 abut against the first housing 3, and the first spring 1 and the second spring 2 are installed inside the housing 3, making the installation of the first spring 1 and the second spring 2 more stable and preventing misalignment of the first spring 1 and the second spring 2, which could lead to damage to the device.

[0056] Preferably, a mounting element (not shown) is formed on the second sub-housing 32, which allows the safety switch to be mounted on a device with a rotating mechanism, thereby increasing the stability of the safety switch.
