Description

Technical Field

[0001] This utility model belongs to the technical field of snap-fit ​​fasteners for quick and easy installation without loosening, and in particular relates to a snap-fit ​​fastener for quick and easy installation without loosening. Background Technology

[0002] In the field of mechanical assembly, snap-fit ​​fasteners are widely used for the quick connection of parts. In existing technologies, these fasteners mostly employ a single-point snap-fit ​​structure, requiring manual pressing or simple tools for installation. However, in vibration environments, single-point snap-fit ​​is prone to stress concentration, leading to snap loosening and connection failure, posing a safety hazard. Furthermore, manual installation requires precise alignment, and installation efficiency is significantly reduced when operating space is limited. Disassembly often requires specialized tools, making it difficult to meet the demands of frequent disassembly and assembly operations. Utility Model Content

[0024] In the following description, embodiments of the snap-fit ​​fastener of the present invention, which is designed to prevent loosening and allow for quick installation, will be described with reference to the accompanying drawings.

[0025] Figure 1-4 This invention illustrates a snap-fit ​​fastening accessory for quick installation and anti-loosening according to an embodiment of the present invention. It includes a housing 1 and a mounting plate 2. A fixing block 6 is fixedly mounted at one end of the housing 1, and a locking block 7 is movably mounted at the other end of the housing 1. A spring 8 is fixedly mounted between the fixing block 6 and the locking block 7. A first limiting plate 5 is fixedly mounted at one end of the housing 1, and a second limiting plate 13 is movably mounted at one end of the first limiting plate 5. A guide ring 18 is movably mounted on the side of the second limiting plate 13, and a limiting rod 17 is movably mounted at one end of the guide ring 18. The limiting rod 17 is arranged in three sets, and a claw 19 is fixedly mounted at one end of each limiting rod 17.

[0026] Specifically, the clamping and locking are completed simultaneously through the dual action of threaded drive and rope traction, ensuring that there is no risk of loosening during the fastening process.

[0027] A rotating shaft 11 is movably mounted on one end of the outer casing 1, and a drive motor 9 is fixedly mounted on one end of the rotating shaft 11. A threaded rod 16 is fixedly mounted on the output end of the drive motor 9.

[0028] Specifically, spring 8 provides a stable restoring force, automatically releasing the locked state upon unlocking, thus improving operational efficiency.

[0029] A limit block 15 is movably installed at one end of the threaded rod 16, and a connecting rope 14 is fixedly installed at one end of the limit block 15. The locking block 7 and the limit block 15 are connected by the connecting rope 14.

[0030] Specifically, the guide ring 18 and the guide groove 12 work together to restrict the movement trajectory, prevent component displacement, and improve assembly accuracy.

[0031] A limit rod 17 is movably installed between the first limit plate 5 and the second limit plate 13, and a limit block 15 is movably installed at one end of the first limit plate 5.

[0032] Specifically, the three sets of jaws 19 move radially in sync, resulting in uniform force distribution and the clamping surface adapting to the shape of the fastener.

[0033] One end of the outer casing 1 has a guide groove 12 that cooperates with the locking block 7, and one end of the mounting plate 2 has a locking block 4 fixedly installed.

[0034] Specifically, the double-sided slots 10 of the card block 4 form a mechanical interlock with the outer shell 1 and the locking block 7, which significantly enhances the anti-starting performance.

[0035] The two ends of the locking block 4 are provided with slots 10 that cooperate with the outer shell 1 and the locking block 7, and the two ends of the mounting plate 2 are provided with bolts 3.

[0036] Specifically, the entire process of clamping, locking, and releasing can be completed by a single motor drive without the need for auxiliary tools. The built-in design of the drive component reduces external space occupation and is suitable for confined installation environments.

[0037] Working Principle: When the user begins using this utility model, the mounting plate 2 is first fixed to the target position and initially positioned using bolts 3. At this time, the outer shell 1, as the main frame, provides guidance and support. One end of the outer shell 1 is fixed with a fixing block 6, and the other end is movably mounted with a locking block 7. The two are connected by a spring 8. The elasticity of the spring 8 provides basic tension for subsequent anti-loosening, ensuring that the components remain in a pre-tightened state during installation. The key at this stage is to ensure that the guide groove 12 is aligned with the locking block 7 so that subsequent movement is smooth. The user activates the drive motor 9, and the output end of the drive motor 9 drives the threaded rod 16 to rotate. The threaded rod 16 is connected to the outer shell 1 through the rotating shaft 11, ensuring a smooth and efficient transmission process. One end of the threaded rod 16 is movably mounted with a limiting block 15, and the limiting block 15 is fixed with a connecting rope 14. The connecting rope 14 transmits power to the locking block 7. This linkage design allows the locking block 7 to move within the guide groove 12, achieving rapid position adjustment. At the same time, a limiting rod 17 is movably mounted between the first limiting plate 5 and the second limiting plate 13, limiting... Positioning rod 17 acts as a guide component, ensuring precise movement and preventing deviation. The movement of locking block 7 drives the action of pawl 19. Pawl 19 is fixedly installed via limiting rod 17. Guided by guide ring 18, pawl 19 extends outward and engages in slot 10 of pawl block 4. Slot 10 is designed to cooperate with housing 1 and locking block 7 to form a reliable mechanical engagement. At this time, the tension of spring 8 continues to act, providing elastic reaction force for the locked state, effectively preventing loosening. The cooperation of limiting block 15 and connecting rope 14 ensures... The position of the locking block 7 is adjustable, allowing users to easily install or remove it. All components are integrated inside the housing 1. The drive motor 9 transmits power through the threaded rod 16 and the limiting block 15, ultimately causing the locking block 7 to complete its stroke within the guide groove 12. The fixing block 6 and the limiting plate 5 inside the housing 1 provide stable support, while the slot 10 of the locking block 4 ensures that the mounting plate 2 is firmly fixed. Through this process, users can quickly install fastening accessories. The continuous tension of the spring 8, combined with the engagement of the claw 19, forms a double anti-loosening guarantee.

[0038] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
