Abstract
Description
Technical Field
[0001] This utility model belongs to the field of locking mechanism technology, specifically relating to a locking mechanism for a mobile phone holder. Background Technology
[0002] A car phone holder is a device that is fixed inside a car (such as the dashboard, center console, windshield, air conditioning vents, CD player, etc.) to safely, securely, and conveniently place and secure a smartphone, so that the driver can use the phone for navigation, hands-free calling, music playback, or to view necessary information, provided that safety regulations are met.
[0003] However, existing car phone holders are generally bulky and complex in structure, which not only take up too much space in the car but also affect the driver's visibility. Many products are cumbersome to install, requiring repeated adjustments of angles, tightening of screws, or even the use of adhesive to fix them. This is time-consuming and may damage the car's interior. More worryingly, these holders often use simple mechanical clamping methods, which are prone to loosening when the vehicle is bumpy, causing the phone to slip and posing a serious safety hazard. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a locking mechanism for a mobile phone holder, which has the advantages of being easy to pick up, not obstructing the view, and having a high driving and safety factor.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a locking mechanism for a mobile phone holder, comprising a base, an internal limiting track of the base, a rotating component disposed on the outside of the base, the rotating component being rotatably connected within the limiting track, and a cover plate disposed on the outside of the rotating component, the cover plate being fixedly connected to the outer surface of the base.
[0006] Preferably, the rotating component has two slots inside, which are symmetrically distributed inside the rotating component. The thickness of the rotating component is no greater than 5 mm, and the outer diameter of the rotating component is no greater than 36 mm.
[0007] Preferably, two locking springs are provided on the inner side of the rotating component, and the two locking springs are horizontally and symmetrically distributed on the inner side of the rotating component.
[0008] Preferably, the cover plate has four correspondingly distributed locking grooves inside, and the locking spring is engaged with the locking groove.
[0009] Preferably, the cover plate has two correspondingly distributed placement slots inside, two locking blocks are inserted into the two placement slots, and the two locking blocks are snapped into the two slots. A mobile phone connector is fixedly connected to the outside of the two locking blocks.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. Quick assembly and disassembly: 90° rotation enables automatic locking or unlocking; simple operation: locking or removing can be done with one hand; ultra-thin and compact: thickness not exceeding 5mm, compatible with mobile devices; four-way positioning: strong stability, suitable for multi-angle use; convenient installation: can be directly adhered to the back of the device without obstruction or loosening; safe to use: stable structure that is not easy to loosen, improving driving safety.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-2 This utility model provides a technical solution: a locking mechanism for a mobile phone holder, including a base 1, an internal limiting track 2 of the base 1, a rotating component 3 disposed on the outside of the base 1, the rotating component 3 being rotatably connected to the limiting track 2, and a cover plate 6 disposed on the outside of the rotating component 3, and the cover plate 6 being fixedly connected to the outer surface of the base 1.
[0017] In this embodiment, the rotating component 3 can slide within the limiting track 2, thereby enabling the two locking blocks 9 externally fixed to the mobile phone connector 7 to complete the locking.
[0018] Specifically, the rotating part 3 has two slots 4 inside, which are symmetrically distributed inside the rotating part 3. The thickness of the rotating part 3 is no more than 5mm, and the outer diameter of the rotating part 3 is no more than 36mm.
[0019] In this embodiment, the two slots 4 facilitate the locking of the two locking blocks 9 and make it easy to drive the rotating part 3 to rotate.
[0020] Specifically, two locking springs 5 are provided on the inner side of the rotating part 3. The two locking springs 5 are horizontally symmetrically distributed on the inner side of the rotating part 3. Four corresponding locking grooves 8 are opened inside the cover plate 6, and the locking springs 5 are engaged in the locking grooves 8.
[0021] In this embodiment, the rotating part 3 can be locked by the cooperation of two locking springs 5 and locking groove 8.
[0022] Specifically, the cover plate 6 has two corresponding placement slots 10 inside, and two locking blocks 9 are inserted into the two placement slots 10. The two locking blocks 9 are snapped into the two slots 4, and a mobile phone connector 7 is fixedly connected to the outside of the two locking blocks 9.
[0023] In this embodiment, the two placement slots 10 allow the locking block 9 to be accurately inserted into the cover plate 6 and accurately engaged in the slot 4.
[0024] The working principle and usage process of this utility model are as follows: During use, the user first fixes the mobile phone connector 7 to the back of the mobile phone, then inserts it into the two placement slots 10. At the same time, the two locking blocks 9 fixed to the outside of the mobile phone connector 7 are engaged in the slot 4. Then, the rotating part 3 is rotated. During rotation, the locking spring 5 is inserted into the locking slot 8 to lock the position. After rotation, rotate 90° clockwise to complete the locking. Rotate 90° counterclockwise to remove the device. It is suitable for one-handed operation and high-frequency use scenarios.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
