Technical Field

[0001] The utility model relates to the technical field of adapters, and mainly relates to an adapter. Background Art

[0002] An adapter is a device used to connect devices that need to adjust the angle, such as lamps and styling combs that need to adjust the angle. The adapters in the prior art generally consist of a fixed part, a rotating part, and a rotating shaft. The rotating shaft is installed through the fixed part and the rotating part, and the rotating part can rotate around the central axis of the rotating shaft. However, when such an adapter structure is applied to a lamp, the lower rod of the lamp is connected to the fixed part, the upper rod is connected to the rotating part, and the upper rod is connected to the lamp head. Since the lamp head is heavy, when a consumer needs to adjust the lamp head upward, one hand needs to hold the upper rod, and the other hand needs to apply a large force to rotate the upper rod, which is difficult to use.

[0024] Please specifically refer to Figures 1-3 , an adapter, comprising a first connecting portion 1, a second connecting portion 2 cooperating with the first connecting portion 1, and a resistance rotating shaft 3 installed inside the second connecting portion 2. Both the first connecting portion 1 and the second connecting portion 2 are hollow structures, and the first connecting portion 1 and the second connecting portion 2 can rotate relative to each other. A first fixing plate 4 is provided in the first connecting portion 1, and the first fixing plate 4 is fixed to the first connecting portion 1 by a fastener. A second fixing plate 5 is provided in the second connecting portion 2, and the second fixing plate 5 is fixed to the second connecting portion 2 by a fastener. Both ends of the resistance rotating shaft 3 are respectively inserted into the first fixing plate 4 and the second fixing plate 5. A torsion spring 6 is sleeved outside the resistance rotating shaft 3, and both ends of the torsion spring 6 are respectively inserted into the first fixing plate 4 and the second fixing plate 5.

[0025] Further, a through hole 7 is formed in the first fixing plate 4 and the second fixing plate 5, and both ends of the torsion spring 6 are respectively inserted into the through holes 7 of the first fixing plate 4 and the second fixing plate 5.

[0026] In this embodiment, the cross-section of the rod body of the resistance rotating shaft 3 is a runway shape, so the perforation for insertion on the first fixing plate 4 is also a runway shape, and the two match. Due to this structural design, when the first connecting portion 1 is rotated, the resistance rotating shaft 3 will also rotate accordingly, and the torsion spring 6 will also deform. With the auxiliary effect of the torsion spring 6, the rotation of the first connecting portion 1 will become easier.

[0027] Further, one end of the resistance rotating shaft 3 is provided with a limiting portion 301, and the other end is provided with a thread. The end of the resistance rotating shaft 3 provided with the limiting portion 301 is inserted into the first fixing plate 4, and the end of the resistance rotating shaft 3 provided with the thread is inserted into the second fixing plate 5, and a nut 9 is installed at this end.

[0028] Further, a plurality of gaskets 10 are sleeved on the resistance rotating shaft 3, and the multiple gaskets 10 are stacked together and installed between the nut 9 and the second fixing plate 5. A sleeve 8 is sleeved outside the resistance rotating shaft 3, and the length of the sleeve 8 is the same as the distance between the first fixing plate 4 and the second fixing plate 5. The designs of the limiting portion 301, the nut 9, the gasket 10 and the sleeve 8 are all for limiting the resistance rotating shaft 3 to prevent the resistance rotating shaft 3 from moving left and right along the central axis of the resistance rotating shaft 3.

[0029] Further, a stop block 101 is provided on the first connecting portion 1, and a movable groove 201 is provided on the outer wall of the second connecting portion 2. The stop block 101 is adapted to the movable groove 201. In this embodiment, the central angle where the movable groove 201 is located is 90°, that is, the relative rotation angle between the first connecting portion 1 and the second connecting portion 2 is between 0 - 90°.

[0030] Further, covers 11 are provided on both sides of the first connecting portion 1.
