Description

Technical Field

[0001] This utility model relates to the field of connecting component technology, and in particular to a four-claw magnetic clasp. Background Technology

[0002] In the fields of jewelry, pet supplies, and industrial connectivity, magnetic snaps are a common structure for quick connection of components, and their ease of assembly and disassembly, as well as connection reliability, directly affect the user experience. Existing magnetic snaps mostly employ a single connection method (such as pure magnetic connection or pure snap-fit), making it difficult to meet the operational needs of different scenarios. For example, jewelry magnetic snaps need to meet the requirement of quick disassembly, while industrial equipment snaps focus more on connection stability and robustness. Traditional structures often cannot simultaneously meet the adaptability of multiple scenarios, forcing users to replace different snaps according to their uses, increasing usage costs and complexity. ZL 2023 2 2313184.4 discloses a connector that is easy to install, using a combination of magnetic attraction and spring telescopic components; however, its connection strength is insufficient, and it is easy to loosen. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a four-claw magnetic clasp that provides a more secure connection and is less prone to loosening.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A four-claw magnetic clasp includes a first connector and a second connector, both equipped with magnetic blocks. The first connector has a receiving cavity for accommodating the magnetic blocks. A spring-pressing telescopic assembly is provided between the first connector and the second connector. The spring-pressing telescopic assembly includes two pressing members, two telescopic members, and a spring. The two ends of the spring are respectively connected to the two telescopic members. One end of the pressing member is a pressing post, and the other end is a U-shaped claw. The telescopic member is a wedge-shaped block that cooperates with the U-shaped claw. The pressing members and telescopic members are symmetrically distributed. The bottom of both the pressing members and the telescopic members is provided with outwardly protruding claws. The claws are interference-fitted with the receiving cavity. Both the claws and the pressing post are embedded in the second connector.

[0005] Furthermore, the connector has two symmetrically distributed through holes on its two side walls, through which the pressing pin passes.

[0006] Furthermore, the connector has four symmetrically distributed through holes on its sidewalls, through which the claws pass.

[0007] Furthermore, the inner side of the U-shaped claw and the outer side of the wedge block are both provided with inclined surfaces. The inclined surface of the U-shaped claw of the left pressing member cooperates with the left inclined surface of the two wedge blocks, and the inclined surface of the U-shaped claw of the right pressing member cooperates with the right inclined surface of the two wedge blocks.

[0008] Furthermore, the magnetic blocks are respectively fixed in the receiving cavity of connector one and at the end of connector two closest to connector one.

[0009] Furthermore, the inner wall of the receiving cavity is provided with three grooves, which are respectively adapted to the two magnetic blocks and the claws.

[0010] Furthermore, the end of the claw is beveled.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. Due to the attraction force, the magnetic block has a positioning function, which facilitates the alignment and connection of connector one and connector two.

[0012] Second, by applying force to the pressing column, the telescopic component is driven to extend and retract, thereby causing the four claws to extend and retract synchronously, making the connection between connector one and connector two firm and easy to disassemble and assemble.

[0018] This application provides a four-claw magnetic snap fastener. By applying force to the pressing post, the telescopic component is moved to extend and retract, thereby causing the four claws to extend and retract synchronously, making the connection between connector one and connector two firm and easy to assemble and disassemble. Example

[0019] like Figure 1-4 As shown, the overall technical solution in this application embodiment is as follows: To address the problems existing in the prior art, this utility model provides a four-claw magnetic clasp, including a connector head 1 and a connector head 2, both equipped with magnetic blocks 6. The connector head 1 has a receiving cavity for accommodating the magnetic blocks. A spring-pressing telescopic assembly is provided between the connector head 1 and the connector head 2. The spring-pressing telescopic assembly includes two pressing members, two telescopic members 4, and a spring 12. The two ends of the spring 12 are respectively connected to the two telescopic members 4. One end of the pressing member is a pressing post 3, and the other end is a U-shaped claw 13. The telescopic member 4 is a wedge-shaped block that cooperates with the U-shaped claw 13. The pressing members and telescopic members 4 are symmetrically distributed. The bottom of both the pressing members 4 and the telescopic members is provided with outwardly protruding claws 5, which are interference-fitted with the receiving cavity. Both the claws 5 and the pressing post 3 are embedded in the connector head 2. The side wall of the connector head 2 has two symmetrically distributed through holes 11, through which the pressing post 3 passes. The connector 2 has four symmetrically distributed through holes 11 on its side wall, and the claw 5 passes through the through holes 11.

[0020] The U-shaped claw 13 has an inclined surface on its inner side and the wedge block has an inclined surface on its outer side. The inclined surface of the U-shaped claw 13 of the left pressing member matches the left inclined surface of the two wedge blocks, and the inclined surface of the U-shaped claw 13 of the right pressing member matches the right inclined surface of the two wedge blocks.

[0021] The magnetic blocks 6 are respectively fixed in the receiving cavity of connector one and the end of connector two closest to connector one.

[0022] The inner wall of the receiving cavity is provided with groove 7, groove 8, and groove 9, which are adapted to the claw 5 and the two magnetic blocks 6 respectively.

[0023] The end of the chuck 5 is a bevel.

[0024] Working principle: When connection is needed, bring connector two close to connector one. The two attract each other magnetically, achieving precise guidance and positioning. Simultaneously press the pressing post. The inclined surface of the U-shaped claw of the pressing component engages with the inclined surface of the telescopic component, causing both the pressing and telescopic components to retract inwards simultaneously. All four claws retract inwards synchronously until they enter groove one, at which point the pressing stops. Under the return action of the spring, both the pressing and retracting components return to their original positions, causing the claws to extend and engage in groove one. At this point, connector one and connector two are securely connected and are unlikely to loosen even under significant external force.

[0025] When disassembly is required, press the pressing column. The inclined surface of the U-shaped claw of the pressing component engages with the inclined surface of the telescopic component, causing both the pressing component and the telescopic component to retract inward simultaneously. All four claws retract inward synchronously until groove one no longer obstructs the horizontal movement of the claws, thus separating connector one from connector two. After complete disassembly, stop pressing. Under the reset action of the spring, both the pressing component and the telescopic component return to their original positions, causing the claws to extend.

[0026] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
