Description

Technical Field

[0001] This utility model relates to the field of mobile phone pendant installation, and in particular to a toggle clip for mobile phone pendants. Background Technology

[0002] With the widespread use of smartphones, they have become more than just communication tools; they have become the center of entertainment, work, and social interaction in people's daily lives. To meet the needs of personalization and functionality, users often equip their phones with various accessories, such as decorative dolls, ring holders, and lanyards. These accessories not only serve a decorative purpose but also improve the stability and security of holding the phone, preventing it from slipping.

[0003] While existing mechanical snap-fit ​​structures partially solve the inconvenience of adhesive methods, they still generally have some drawbacks. For example, some snap-fits use a simple insert structure, which lacks reliable locking and is prone to accidental detachment when subjected to external force, leading to the risk of losing the pendant or phone. Other snap-fits may use knobs or screws for fixing, which, although providing sufficient locking force, are cumbersome to operate, requiring both hands or even tools, making quick and convenient assembly and disassembly extremely inconvenient.

The locking mechanism includes a drive lever that is slidably disposed on the back cover of the mobile phone, a dial that is rotated and disposed in the back cover of the mobile phone under the drive of the drive lever, and at least two locking pieces that are circumferentially distributed on the dial along the axis of the dial. The dial is provided with a plurality of toggle pins that correspond one-to-one with each locking piece. Each locking piece is provided with a toggle pin. The moving arc groove is provided, and each actuating pin is slidably disposed in the corresponding moving arc groove. Each locking piece has a driving slider on its end face away from the actuating disk. The fixed base has a sliding guide groove corresponding to each driving slider. Each driving slider is slidably disposed in the corresponding sliding guide groove. The moving arc grooves on each locking piece and the sliding guide grooves on the fixed base are circumferentially distributed along the axis of the actuating disk. Each locking piece is slidably connected between the fixed base and the actuating disk through the rotation of the actuating disk, the sliding engagement of each actuating pin with the moving arc groove, and the sliding engagement of the driving slider with the sliding guide groove. The buckle is fixedly connected to the fixed base and the actuating disk after being inserted into the slot and after each locking piece extends into the annular groove.

[0006] Furthermore, the aforementioned fixed base includes an annular base and a base plate portion disposed at the bottom of the annular base. Each sliding guide groove is disposed on the base plate portion, and each sliding guide groove extends away from the outer sidewall of the annular base along the inclined direction between the circumferential and radial directions of the base plate portion.

[0007] Furthermore, the aforementioned sliding guide groove is provided with a first groove end and a second groove end. The first groove end is located at one end of the sliding guide groove near the annular base. The actuating arc groove is provided with a third groove end and a fourth groove end. The third groove end is located at one end of the actuating arc groove near the drive slider, and the fourth groove end is located at one end of the actuating arc groove away from the drive slider. When each locking piece has not entered the annular groove, the drive slider is pressed against the second groove end, and the actuating pin is pressed against the fourth groove end. When each locking piece enters the annular groove, the drive slider slides from the second groove end to the first groove end, and the actuating pin slides from the fourth groove end to the third groove end.

[0008] Furthermore, the aforementioned drive lever includes a lever portion, a toggle groove disposed on the lever portion, and a toggle plate disposed on the lever portion and slidably disposed on the back cover or side of the back cover of the mobile phone. The back of the toggle disc is provided with a drive shaft corresponding to the toggle groove. The drive shaft is slidably disposed in the toggle groove. The toggle plate drives the drive lever to move downward by sliding down.

[0012] Furthermore, the end face of the buckle with the connecting rod is flush with the end face of the annular base after the buckle is inserted into the slot.

[0013] This utility model has positive effects: (1) By moving the drive lever downward, the drive lever drives the dial to rotate. During the rotation of the dial, the sliding cooperation between each drive pin and the drive arc groove, and the sliding cooperation between each drive slider and the sliding guide groove, drives each locking piece to move between the fixed base and the dial. When the buckle is inserted into the slot, each locking piece slides into the ring groove and fixes the buckle in the slot. This effectively solves the problems of difficult disassembly and easy accidental contact in the prior art, greatly improves the efficiency and convenience of connecting the buckle and the plug, as well as the hanging on the buckle and the back cover of the mobile phone. At the same time, it greatly improves the efficiency of the installation and disassembly of the hanging piece, and effectively prevents the hanging piece from falling off due to accidental pulling. In addition, through the connection between the buckle and the slot, it is also convenient for the user to connect the hanging piece and the buckle, avoiding the problem that the hanging piece cannot be quickly installed due to jamming or dead angle during the installation process. The structure is ingenious, convenient and practical.

[0014] (2) By setting the fixed base as a connection between the ring base and the base plate, and setting the extension direction of the sliding guide to extend obliquely along the direction between the circumferential and radial directions of the base plate, the moving direction of each locking piece can be limited, and the stability of each locking piece during the movement process can be guaranteed, which is efficient and convenient.

[0015] (3) By setting a first groove end and a second groove end on the sliding guide, and setting a third groove end and a fourth groove end on the actuating groove, the present invention clarifies the accurate position of the driving slider and the actuating pin when the lock piece is in the initial position, and clarifies the direction of movement of the driving slider and the actuating pin during the movement of the lock piece, thus ensuring the stable movement of the lock piece and avoiding interference between the lock pieces during the movement process, making it stable and practical.

[0016] (4) By cooperating with the drive shaft and the drive lever on the drive lever, the linear motion of the lever is converted into the circular motion of the drive plate during the downward movement of the drive lever, thereby realizing the cooperation between each locking piece and the ring groove, and effectively ensuring the stability of the overall operation.

[0017] (5) By setting a compression spring, the continuous force of the compression spring allows the drive lever to automatically return to the locked position after the user releases the lever plate. It also provides damping to the lever plate when it slides, and further improves the stability of the drive lever during the lifting and lowering process.

[0018] (6) By setting a side buckle plate, the length of the side buckle plate is set to be greater than or equal to the sum of the width of the base plate, the width of the locking piece and the width of the toggle plate, and a buckling part is set on the side buckle plate, thereby ensuring the stability of the connection between the fixed base, each locking piece and the toggle plate, and also ensuring the overall stability of the toggle buckle. At the same time, it effectively prevents dust and debris from entering the mechanism, avoids jamming or failure due to contamination, and improves the durability and reliability of the product.

[0019] (7) The present invention provides a buckle groove on the buckle block and a connecting rod on the buckle groove. The design of the buckle groove and the connecting rod enhances the applicability of the product and allows for easy connection or rotation of various hanging parts. This greatly improves the convenience of connecting the buckle block with various hanging parts, making it efficient and practical.

[0020] (8) The present invention sets the end face of the buckle block to be flush with the end face of the fixed base, forming a smooth surface without protrusions, which enhances the overall aesthetics. Attached Figure Description
