Description

Technical Field

[0001] The utility model relates to the field of mobile phone chargers, in particular to a waterproof mobile phone charger. Background Art

[0002] Mobile phone chargers can be roughly divided into travel chargers, desktop chargers and maintenance chargers. Most users are exposed to the first two types, while the most popular ones on the market are travel chargers. There are also many types of travel chargers, including cheap duck egg-shaped micro travel chargers, ordinary desktop card-type chargers, and high-end desktop chargers with LCD displays.

[0003] A prior art utility model patent, CN 218275268 U, proposes a waterproof mobile phone charger. A retaining ring is movably disposed on the outside of the charging port, and the retaining ring and the charger body are elastically connected via a guide rod and a return spring. This prevents moist air from entering the charging port. Furthermore, it effectively prevents water from entering the charging port, which could reduce the lifespan of the charger body or even damage it.

[0004] However, its dustproof range is small, and the flexible sheet is easily squeezed when plugging in and unplugging the charging cable, causing it to deform. After deformation, its sealing effect will be seriously reduced, and it will no longer be able to block the impact of dust and water stains on the interface. At the same time, it does not have the ability to conveniently wind and rewind the charging cable, and the charging cable needs to be stored separately. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1As shown in Figure 4, this embodiment provides a waterproof mobile phone charger, including a device body 1, which contains an outer shell 2, a charging cable 6, a sealing assembly 7, and a winding assembly 8. A plug 3 is provided at the upper end of the outer shell 2, and a first interface 4 and a second interface 5 are provided at the lower end of the outer shell 2. The charging cable 6 is correspondingly plugged into the first interface 4 and the second interface 5. The sealing assembly 7 is installed on the outside of the first interface 4 and the second interface 5. An inner groove 21 is provided on the side wall of the outer shell 2, and a limiting hole 23 is provided in the inner groove 21. The winding assembly 8 is installed in the inner groove 21.

[0025] Preferably, the sealing assembly 7 includes a mounting seat 71, with slots 72 on both sides of the mounting seat 71, a mounting sleeve 73 provided on the outside of the mounting seat 71 and elastic clamps 74 on both sides of the mounting sleeve 73, a bamboo sleeve 75 connected to the outer end of the mounting sleeve 73, and a sealing rubber ring 76 provided on the outside of the bamboo sleeve 75. The mounting seat 71 is fixed to the lower end of the outer shell 2, and the mounting seat 71 is provided with two groups and is respectively sleeved on the outside of the first interface 4 and the second interface 5. The mounting sleeve 73 is sealed and plugged with the mounting seat 71, and the elastic clamp 74 is correspondingly engaged with the slots 72. The mounting sleeve 73 and the bamboo sleeve 75 are movably sleeved on the outside of the charging cable 6, and the sealing rubber ring 76 is tightly sleeved on the charging cable 6;

[0026] The mounting seat 71 and the mounting sleeve 73 facilitate the installation and fixation of the bamboo sleeve 75. The bamboo sleeve 75 and the sealing rubber ring 76 cooperate to protect the connection between the two sets of interfaces and the charging cable 6 to prevent them from being affected by dust or water and causing problems such as poor contact. The structure is simple and easy to disassemble and assemble, which increases the safety and practicality of the device.

[0027] Preferably, the winding assembly 8 includes a winding rod 81, a movable groove 82 is opened in the winding rod 81, a spring 83 is provided in the movable groove 82, and the outer end of the spring 83 is connected to a movable shaft 84, a push-pull block 85 is provided on one side of the movable shaft 84, and a side block 86 is provided on the outer end of the winding rod 81. The winding rod 81 is rotatably installed in the embedded groove 21, and a limit block 22 is provided on the outer side of the embedded groove 21. The winding rod 81 rotates and fits with the limit block 22, and the movable shaft 84 passes through the movable groove 82 and corresponds to the limit hole 23;

[0028] The push-pull block 85 and the spring 83 cooperate to control the telescopic movement of the movable shaft 84. The movable shaft 84 cooperates with the limiting hole 23 to facilitate the rotation, folding and limiting of the winding rod 81, thereby facilitating the winding and wrapping of the charging cable 6 for easy storage and organization.

[0029] The principle and process of use of the present invention are as follows: when using, the installation sleeve 73, bamboo sleeve 75 and sealing rubber ring 76 can be installed on the charging cable 6 from the outer end of the charging cable 6, so that the sealing rubber ring 76 is tightened on the outside of the charging cable 6, and then the charging cable 6 is connected to the first interface 4 or the second interface 5. After the connection is in place, the installation sleeve 73 is inserted into the mounting seat 71 and the elastic clamp head 74 is clamped into the clamping groove 72. At this time, the connection between the two groups of interfaces and the charging cable 6 can be sheathed and protected under the stretching action of the bamboo sleeve 75, avoiding It is protected from the effects of dust or water and problems such as poor contact. It has a simple structure and is easy to assemble and disassemble, and is flexible to use. When not in use, the push-pull block 85 can be squeezed inward and moved. The push-pull block 85 drives the movable shaft 84 to squeeze the spring 83, so that the movable shaft 84 disengages from the limiting hole 23 and shrinks into the movable groove 82. At this time, the winding rod 81 can be turned out and attached to one side of the limiting block 22, and the charging cable 6 can be wound around the two sets of winding rods 81. There is no need to place the charging cable 6 separately to avoid it being easily damaged or lost.
