Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of adapters, in particular to a detachable DC adapter. Background Art
[0002] A DC adapter is a connector used to convert the DC (direct current) power interface. Through it, a DC interface of one specification can be converted into another specification to connect different electronic devices or power adapters. There are various specifications for DC adapters, such as the common 5.5*2.1mm, 3.5*1.35mm, etc. These specifications usually refer to the outer diameter and inner diameter dimensions of the interface. According to the different shapes and uses of the interfaces, DC adapters can be divided into various types such as straight plug type, tuning fork type, etc.
[0003] In the existing tuning fork type DC adapter, usually one terminal protrudes from the adapter body, while the other terminal is hidden inside the adapter body. Since the protruding terminal is directly exposed, during daily use or storage, the adapter is likely to roll off the table and damage the terminal, resulting in a poor protection effect on the terminal.
[0004] Therefore, we propose a detachable DC adapter to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a detachable DC adapter to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A detachable DC adapter includes an adapter body, a terminal one and a terminal two respectively connected to both ends of the adapter body. One end of the outer wall of the adapter body is provided with a stepped surface, and the other end of the outer wall of the adapter body is connected with a limiting ring. A protective sleeve is movably sleeved between the limiting ring and the stepped surface. The protective sleeve moves axially along the terminal one to entirely cover the terminal one. A limiting structure for controlling the positioning of the protective sleeve is further provided between the protective sleeve and the adapter body.
[0008] In a further embodiment, the limiting structure includes a threaded ring. The outer ring of the threaded ring is fixed to the inner wall of the end of the protective sleeve close to the stepped surface, and the inner ring of the threaded ring is in threaded connection with the outer wall of the adapter body.
[0009] In a further embodiment, the limiting structure includes a convex ring one and a convex ring two. The convex ring one is fixed to the inner wall of the end of the protective sleeve close to the stepped surface. The convex ring two is symmetrically fixed on the outer walls of the adapter body close to the stepped surface and the limiting ring respectively, and the convex ring one and the convex ring two are staggered with each other.
[0010] In a further embodiment, the limiting ring is a silicone ring. When the limiting ring is wound outward, it protrudes from the outer wall of the adapter body. When the limiting ring is reset, its outer diameter is smaller than the outer diameter of the adapter body.
[0011] In a further embodiment, the outer shape of the protective sleeve adopts a polygonal structure.
[0012] In a further embodiment, buffer strips are wrapped around all the outer yang corners of the protective sleeve.
[0013] In a further embodiment, a number of anti-slip protrusions are provided on the outer plane of the protective sleeve.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] The present utility model is provided with a protective sleeve that can be telescopically movable relative to the adapter body. When the adapter is in use, the protective sleeve can be sleeved outside the adapter body, and when the adapter is not in use, the protective sleeve can be moved outside the terminal one, so as to entirely cover the terminal one and protect the terminal one. This can not only reduce the situation where the adapter rolls off the table, but also effectively prevent the problem of damaging the terminal one. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two.
[0023] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-3, A detachable DC adapter, including an adapter body 1. One end of the adapter body 1 is connected with a terminal one 2, and a terminal two 3 is installed inside the other end of the adapter body 1. A stepped surface 11 is provided on the outer wall of the adapter body 1 near the terminal two 3, and a limiting ring 5 is connected to the outer wall of the adapter body 1 near the terminal one 2. A protective sleeve 4 is movably sleeved between the limiting ring 5 and the stepped surface 11. When the protective sleeve 4 moves axially along the terminal one 2, it can entirely cover the terminal one 2, thus hiding the terminal one 2 inside the protective sleeve 4, achieving the effect of protecting the terminal one 2 and reducing the problem of the terminal one 2 being damaged by knocking. The limiting ring 5 is a silicone ring. When the limiting ring 5 is wound outward, it protrudes from the outer wall of the adapter body 1, thereby preventing the protective sleeve 4 from slipping out of the adapter body 1. And when the limiting ring 5 resets, its outer diameter is smaller than the outer diameter of the adapter body 1, enabling the protective sleeve 4 to be conveniently detached from the adapter body 1. To improve the use stability of the protective sleeve 4, a limiting structure is provided between the protective sleeve 4 and the adapter body 1. This limiting structure can prevent the protective sleeve 4 from moving arbitrarily when it is sleeved around the adapter body 1 or the terminal one 2.
[0026] Please refer to Figure 4 , Embodiment 1: The limiting structure includes a threaded ring 6. The outer ring of the threaded ring 6 is fixed to the inner wall of the end of the protective sleeve 4 near the stepped surface 11, and the inner ring of the threaded ring 6 is in threaded connection with the outer wall of the adapter body 1. By rotating the protective sleeve 4 to drive the threaded ring 6 to rotate, and then using the threaded action between the threaded ring 6 and the adapter body 1, the protective sleeve 4 moves axially during rotation. When rotated until the threaded ring 6 is close to the limiting ring 5, the protective sleeve 4 just completely covers the terminal one 2.
[0027] Please refer to Figure 5 , Embodiment 2: The limiting structure includes a convex ring one 7 and a convex ring two 8. The convex ring one 7 is fixed to the inner wall of the end of the protective sleeve 4 near the stepped surface 11, and the convex ring two 8 is symmetrically fixed on the outer walls of the adapter body 1 near the stepped surface 11 and the limiting ring 5 respectively. When the convex ring one 7 is stuck between the convex ring two 8 and the stepped surface 11, the protective sleeve 4 is sleeved around the adapter body 1. When the convex ring one 7 is stuck between the convex ring two 8 and the limiting ring 5, the protective sleeve 4 just completely covers the terminal one 2.
[0028] Please refer to Figures 1-3 , To further improve the protection effect of the protective sleeve 4, the outer shape of the protective sleeve 4 is set to be a polygonal structure, making its surface a non-circular surface structure, thereby reducing the risk of it rolling off the tabletop. At the same time, buffer strips 41 are wrapped around the outer external angles of the protective sleeve 4. The buffer strips 41 are made of silicone or rubber materials, which can not only achieve an anti-slip effect but also reduce the damage caused by knocking.
[0029] Please refer to Figures 1-3, to facilitate the user to rotate the protective cover 4, a number of anti-slip protrusions 42 are provided on the outer plane of the protective cover 4 to increase the surface friction, thereby reducing the problem of slipping during rotation or pulling movement.
