Description

Technical Field

[0001] This application relates to the field of switches, and in particular to a magnetic switch for children's play. Background Technology

[0002] In recent years, with the increasing emphasis on children's physical and mental health and all-round development, the children's playground industry has ushered in a golden age of vigorous development. From the early rudimentary and simple basic equipment to today's comprehensive playground system integrating fun, education, and innovation, children's playgrounds have not only greatly enriched children's after-school life but also provided them with an ideal platform to cultivate social skills and explore the world. Through diverse entertainment projects and interactive experiences, children can learn in joy and grow through play, making children's playgrounds an important part of modern family leisure time. This development trend not only reflects the improvement of people's living standards but also embodies the attention and investment of the whole society in the healthy growth of the next generation. In the face of potential safety issues that children may encounter during play, the industry has been committed to exploring effective protection strategies. To prevent children from being scratched by sharp edges on the facilities, smoothing the surface and blunting the edges has become the most basic and common approach. This effectively reduces the possibility of direct contact injury, especially for playgrounds equipped with door locks or cabinet locks, which mainly rely on inserting a matching key into the lock cylinder and turning it to open the cabinet door. While the methods described above improve the safety of children's play areas to some extent, significant drawbacks remain. Even with refined finishing of the external edges of the facilities, the sharp edges of existing keys still pose a risk of scratching and could potentially cause accidental injury to children. This potential risk seriously threatens children's personal safety during play. Utility Model Content

[0003] In order to ensure the personal safety of children when opening cabinet doors and to avoid accidental injury to children from the sharp parts of existing keys, this application provides a magnetic switch for children's play.

[0004] This application provides a magnetic switch for children's play, including a magnetic lock and a magnetic key. The magnetic lock includes a mounting base for connecting to a cabinet door, a latching structure rotatably mounted on the mounting base for engaging the cabinet door, a first magnetic element disposed on the latching structure, and a torsion spring disposed between the latching structure and the mounting base. The magnetic key includes a handle portion and a magnetic part disposed on one side of the handle portion. The magnetic part is provided with a second magnetic element, which magnetically engages with the first magnetic element. By adopting the above technical solution, the magnetic lock includes a mounting base, a latching structure, and a torsion spring. The latching structure is provided with a first magnetic element, and the magnetic part of the magnetic key is provided with a second magnetic element. When the second magnetic element and the first magnetic element are close together to form a magnetic engagement, the magnetic force overcomes the elastic force of the torsion spring, causing the latching structure to rotate, thereby realizing the unlocking function. When the second magnetic element moves away from the first magnetic element, the latching structure returns to its original position under the restoring force of the torsion spring. Compared to the traditional method of using sharp keys, this magnetic switch eliminates the need for a sharp key to be inserted into the lock cylinder, avoiding the risk of children being scratched by the sharp part of the key and improving children's safety during play. Simultaneously, the magnetic locking mechanism is simple and convenient to operate, meeting the characteristics of easy-to-use children's play equipment. Preferably, the latch structure is provided with a locking part for engaging with the cabinet door. By adopting the above technical solution, the latch structure is provided with a locking part for engaging with the cabinet door. Due to the presence of the locking part, the latch structure can achieve a stable engagement with the cabinet door. When it is necessary to close the cabinet door, the locking part can firmly lock the cabinet door, preventing the cabinet door from opening arbitrarily, providing a reliable locking function for the cabinet door, thereby effectively ensuring that the cabinet door will not cause safety hazards due to accidental opening during the use of children's play equipment, greatly improving the safety of children's play equipment. Preferably, the latch structure is L-shaped, with the locking part located at the end of the L-shaped structure, and the root of the L-shaped structure rotatably mounted on the mounting base. By adopting the above technical solution, the latch structure is designed in an L-shape, with its base rotatably mounted on the mounting base, allowing the latch structure to rotate around its base. When the cabinet door needs to be opened, the magnetic key interacts with the magnetic component on the latch structure, generating a magnetic force that drives the latch structure to rotate around its base. Since the locking part is located at the end of the L-shape, its position changes during the rotation of the latch structure, thus achieving the action of disengaging from or locking the cabinet door. Compared to traditional switches, this operation is more convenient and flexible. Furthermore, this structure is simple and stable, reducing the probability of mechanical failure, improving the lifespan and reliability of the switch, and thus ensuring the safety and stability of children's play equipment during use. The first magnetic component is embedded in the bend of the L-shape.By adopting the above technical solution, the first magnetic component is embedded in the bend of the L-shaped structure. On the one hand, this position is relatively concealed, making the first magnetic component less susceptible to external impacts and wear, ensuring its magnetic stability, and thus guaranteeing the stability of the magnetic attraction. On the other hand, from a mechanical point of view, the bend of the L-shaped structure is near the critical position for the rotation of the locking structure. When the second magnetic component approaches the first magnetic component to form a magnetic attraction, it is easier to drive the locking structure to rotate, improving ease of use. At the same time, it can also reduce the stress on components such as torsion springs, extending their service life. Preferably, the mounting base is provided with a receiving groove for accommodating the locking structure. The locking structure is rotatably disposed in the receiving groove, and when the locking structure rotates, the snap-fit ​​portion protrudes from the opening of the receiving groove. By adopting the above technical solution, the mounting base is provided with a receiving groove, which can accommodate the locking structure therein, preventing the locking structure from being exposed when not in use and causing interference or damage to surrounding objects or people. The latching structure can rotate within the receiving groove. When the cabinet door needs to be opened, the latching structure rotates, causing the engaging part to protrude from the groove. The engaging part can smoothly engage or disengage with the cabinet door, thereby realizing the locking and unlocking function of the magnetic switch, ensuring the stability and reliability of the magnetic switch operation. Preferably, the mounting base is provided with a limiting boss, which is used to limit the rotation angle of the latch. By adopting the above technical solution, the mounting base is provided with a limiting boss. Due to the presence of the limiting boss, when the latch rotates, it will be blocked by the limiting boss, thus preventing unlimited rotation. In this way, the rotation angle of the latch can be precisely limited, so that the latch can only rotate within a specific range. On the one hand, it can ensure the accuracy of opening and closing of the magnetic switch, avoiding the situation where the latch cannot properly engage with the cabinet door or cannot be unlocked smoothly due to excessive rotation; on the other hand, it can prevent the latch from colliding or rubbing against other components due to excessive rotation angle, reducing component wear and extending the service life of the magnetic switch. Preferably, the magnetic suction part is a hemispherical structure, the handle part is a hollow ring structure, the handle part is connected to the arc-shaped end of the magnetic suction part, and the second magnetic element is embedded in the planar end of the magnetic suction part. By adopting the above technical solution, the magnetic suction part adopts a hemispherical structure, which has no sharp edges and corners, preventing scratches to children during use; the handle part is a hollow ring structure connected to the arc-shaped end of the magnetic suction part, making it convenient for children to grip the hollow structure with their fingers, conforming to children's hand operating habits, and improving the convenience and comfort of use. At the same time, the second magnetic element embedded in the planar end of the magnetic suction part makes the magnetic attraction between the magnetic suction part and the first magnetic element on the magnetic lock more stable and efficient, ensuring that the switch can be opened and closed smoothly, improving the reliability and practicality of the magnetic switch, and thus better ensuring the safety and convenience of children using amusement facilities equipped with this magnetic switch during play.Preferably, the annular structure of the handle is formed by connecting two arc-shaped structures, which are designed to fit a child's fingers. By adopting the above technical solution, since the annular structure of the handle is formed by connecting two arc-shaped structures designed to fit a child's fingers, the child's fingers and handle are perfectly aligned when using the magnetic key, conforming to ergonomics, improving the child's grip comfort, reducing hand fatigue, and making it easier and more convenient for children to operate the magnetic key to open the magnetic lock, thereby improving the child's experience and enthusiasm for using the magnetic switch. Preferably, a buffer pad is provided on the contact surface between the mounting base and the cabinet door. By adopting the above technical solution, a buffer pad is provided on the contact surface between the mounting base and the cabinet door. When the magnetic lock contacts or collides with the cabinet door, the buffer pad can play a buffering role. This is because the buffer pad has a certain degree of elasticity and will deform under pressure to absorb energy. In this way, on the one hand, it can reduce wear between the two, extending the service life of the magnetic lock and the cabinet door; on the other hand, it can reduce the noise generated by the collision, making the process of opening and closing the cabinet door quieter and improving the user experience. Preferably, both the magnetic lock and the magnetic key have chamfered edges. By adopting the above technical solution, chamfering the edges of the magnetic lock and magnetic key avoids the risk of scratches caused by sharp edges. When children use the magnetic switch to open the doors of amusement park equipment, they will not be scratched by accidentally touching the edges of the magnetic lock or magnetic key, greatly improving children's personal safety during play and reducing the possibility of accidental injuries.

[0005] In summary, this application includes at least one of the following beneficial technical effects:

[0006] 1. By using a magnetic lock and magnetic key, the second magnetic component of the magnetic part is brought close to the first magnetic component of the latch structure to form a magnetic attraction to unlock the lock, replacing the traditional method of inserting a key into the lock cylinder and rotating it. This avoids the risk of scratches caused by the sharp part of the existing key and ensures the personal safety of children during play.

[0007] 2. The magnetic key's handle is a hollow ring structure connected by two arc-shaped structures that fit a child's fingers. This design conforms to the characteristics of a child's hand, making it easy for children to use. At the same time, this design has no sharp parts, reducing the risk of scratches.

[0008] 3. Because the corners of both the magnetic lock and the magnetic key are beveled, sharp edges are eliminated, further reducing the possibility of scratching children. Attached Figure Description

[0013] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0014] This application provides an embodiment of a magnetic switch for children's play equipment, referring to... Figure 1 and Figure 2 The system includes a magnetic lock 1 and a magnetic key 2. The magnetic lock 1 is installed on the inside of the cabinet door, and the magnetic key 2 can be tightly attached to the outside of the cabinet door to form a magnetic attraction with the magnetic lock 1 on the inside. This allows for convenient and safe opening and closing of the cabinet door, effectively avoiding the risk of children being scratched by the sharp part of a traditional key, and ensuring the safety of children during play. In particular, the corners of both the magnetic lock 1 and the magnetic key 2 in this embodiment are chamfered. The chamfered design makes these corners smooth, preventing children from being scratched during contact and further improving safety. Specifically, the magnetic lock 1 in this embodiment includes a mounting base 11 for connecting to the cabinet door, a latching structure 12 rotatably disposed on the mounting base 11 for engaging the cabinet door, and a torsion spring 14 disposed between the latching structure 12 and the mounting base 11. The mounting base 11 is made of environmentally friendly plastic and is firmly installed on the inside of the cabinet door with screws. The surface of the mounting base 11 that contacts the cabinet door is flat, and screw holes are provided at its four corners. Screws pass through the screw holes to firmly fix the mounting base 11 to the surface of the cabinet door. In this embodiment, the top surface of the mounting base 11 is flat, and a receiving groove 15 is provided on the top surface of the flat surface. The locking structure 12 is rotatably disposed in the receiving groove 15. In particular, a buffer pad 17 is provided between the contact surface of the mounting base 11 and the cabinet door. The buffer pad 17 is made of a soft material such as rubber or silicone. The buffer pad 17 is glued to the surface of the mounting base 11 in contact with the cabinet door. When the mounting base 11 contacts the cabinet door, it can reduce the impact force, reduce noise, and prevent the mounting base 11 from causing wear to the surface of the cabinet door.

[0015] Furthermore, in this embodiment, the mounting base 11 is provided with a limiting boss 16 near the root of the locking structure 12, and the limiting boss 16 protrudes from one side of the groove opening of the receiving groove 15 of the mounting base 11. When the locking structure 12 rotates to push out the locking structure 12 latching part 121, the locking structure 12 abuts against the limiting boss 16 to restrict the continued rotation of the lock, ensuring that the locking structure 12 can only rotate within a certain angle range, avoiding excessive rotation that would cause it to malfunction. Specifically, the locking structure 12 in this embodiment has an overall L-shaped structure. It is equipped with a latching part 121 for latching the cabinet door. The latching part 121 is located at the end of the L-shaped structure. This latching part 121 is a protruding cuboid block. The locking structure 12 is embedded in the receiving groove 15, and the latching part 121 protrudes from the groove of the receiving groove 15. When the locking structure 12 of the L-shaped structure rotates, the end of the locking structure 12 pushes upward, so that the latching part 121 pushes upward, so that it can be firmly latched into the corresponding slot on the cabinet door, thereby locking the cabinet door. Specifically, the root of the L-shaped structure is rotatably mounted on the mounting base 11 through a pin in the receiving groove 15. The root of the L-shaped structure is provided with a through hole, and the mounting base 11 is provided with a corresponding mounting hole for mounting the pin. The pin passes through the through hole at the root of the L-shaped structure and the corresponding mounting hole on the mounting base 11, and retaining rings are installed at both ends of the pin to prevent the pin from falling off. In this way, the locking structure 12 can rotate around the pin, thereby realizing the operation of opening and closing the cabinet door. A first magnetic element 13 is embedded at the bottom of the bend of the L-shaped structure. The first magnetic element 13 can be a permanent magnet, such as a neodymium iron boron magnet. A groove adapted to the shape and size of the first magnetic element 13 is pre-cut at the bottom of the bend of the L-shaped structure. The first magnetic element 13 is tightly embedded in the groove and fixed with glue. A protective cover is then added to protect the first magnetic element 13, ensuring its stability and the effectiveness of its magnetic effect. Specifically, in this embodiment, a torsion spring 14 is disposed between the locking structure 12 and the mounting base 11. Specifically, one end of the torsion spring 14 is hooked into a small hole on the locking structure 12, and the other end is hooked into a corresponding small hole on the mounting base 11. When the locking structure 12 rotates, the torsion spring 14 deforms and stores elastic potential energy. When the external force disappears, the torsion spring 14 returns to its original shape, driving the locking structure 12 back to its original position. Furthermore, when closing the cabinet door, pressing the door directly engages it due to the presence of the torsion spring 14. The torsion spring 14, made of spring steel, has a suitable elastic coefficient to ensure the latch structure 12 can rotate and reset normally. (Refer to...) Figure 3Specifically, the magnetic key 2 in this embodiment includes a handle 21 and a magnetic suction part 22 disposed on one side of the handle 21. The magnetic suction part 22 has a hemispherical structure, which is round and smooth without sharp edges and corners, effectively preventing scratches to children. The handle 21 has a hollow ring structure, formed by connecting two arc-shaped structures 211. These two arc-shaped structures 211 are specially designed as "grips" to fit children's fingers, allowing children to comfortably and firmly grip the magnetic key 2. In this embodiment, the ends of the two arc-shaped structures 211 and the arc-shaped ends of the magnetic suction part 22 are made of environmentally friendly plastic through an integral molding process. A second magnetic element 23 is embedded in the flat end of the magnetic suction part 22. A blind hole adapted to the second magnetic element 23 is pre-drilled in the flat end of the magnetic suction part 22. The second magnetic element 23 is inserted into the blind hole and fixed with glue. Then, a protective sleeve is fitted on the flat end to protect the second magnetic element 23. The second magnetic element 23 can also be a permanent magnet, which cooperates with the first magnetic element 13 to produce a magnetic attraction. The implementation principle of this embodiment is as follows: The magnetic lock 1 is installed on the inside of the cabinet door. Its mounting base 11 is fixed with screws and a buffer pad 17 is placed between it and the cabinet door to reduce impact, reduce noise, and prevent wear. The latch structure 12 is L-shaped and embedded in the receiving groove 15 of the mounting base 11. The root can be rotated by a pin. The locking part 121 protrudes from the groove. When rotating, the end pushes upward to make the locking part 121 lock into the cabinet door slot to achieve locking. The first magnetic element 13 is embedded in the bend of the latch structure 12. The torsion spring 14 is located between the latch structure 12 and the mounting base 11. One end hooks the small hole of the latch structure 12 and the other end hooks the small hole of the mounting base 11. When the latch structure 12 rotates, the torsion spring 14 deforms and stores energy. After the external force disappears, it drives the latch structure 12 to reset. When the cabinet door is closed, pressing can achieve press locking. The magnetic part 22 of the magnetic key 2 is hemispherical and the handle part 21 is in the middle. The hollow ring structure consists of an arc-shaped structure 211 that fits a child's finger, with a second magnetic element 23 embedded in the flat end of the magnetic part 22. The mounting base 11 has a limiting protrusion 16 near the base of the locking structure 12. When the locking structure 12 rotates and the latching part 121 pushes out, it abuts against the limiting protrusion 16 to limit the rotation angle and ensure normal operation. The magnetic key 2 is close to the outside of the cabinet door. The first and second magnetic elements 23 work together to generate a magnetic attraction, enabling the cabinet door to be opened and closed conveniently and safely. This ensures the personal safety of children when opening the cabinet door and avoids the possibility of accidental injury to children caused by the sharp parts of existing keys.

[0016] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
