DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, an embodiment of the utility model provides a rotating shaft structure for medical devices, comprising: a first joint 1 and a second joint 2, a connecting assembly 3 is arranged between the first joint 1 and the second joint 2, the connecting assembly 3 comprises a first movable member 301 and a second movable member 302, the first movable member 301 is movably connected with the second movable member 302, a limiting member 303 is arranged at one end of the second movable member 302, and the limiting member 303 is clamped with the first movable member 301;

[0023] Currently, in some traditional designs, medical devices that require two main bodies to be connected generally use a rotating shaft to connect the two ends. For example, a toothbrush includes a drive end and a water outlet end. After the two ends are assembled using traditional devices, one or both ends cannot be rotated independently, which has certain defects.

[0024] Specifically, Figures 1 to 4 As shown, after the first connector 1 and the second connector 2 are connected to the medical device, the first connector 1 and the second connector 2 are segmented through the connecting component 3 therebetween, so that when in use, the limiting component 303 is pulled from the second movable part 302 to one end and taken out from the first movable part 301. At this time, one end of the first movable part 301 can be rotated on the side of the second movable part 302, thereby achieving the effect of adjusting the angle according to the usage, improving the flexibility after connection, and effectively avoiding the above-mentioned problems.

[0025] Further, the first movable member 301 includes a movable plate 3011, and the second movable member 302 includes a fixed plate 3021. The movable plate 3011 and the fixed plate 3021 are both fixedly mounted with an inner lining 304 at one end, and the inner lining 304 is clamped with the first joint 1 or the second joint 2;

[0026] Specifically, Figure 1 and Figure 2As shown, the lining 304 on one side of the movable plate 3011 and the fixed plate 3021 is fixed in the first joint 1 and the second joint 2 respectively, so that the first movable part 301 and the second movable part 302 are in more complete contact with the first joint 1 and the second joint 2 respectively, thereby improving the firmness of use and extending the service life.

[0027] Furthermore, a ring groove 3013 is provided at the other end of the movable plate 3011, and a circular ring 3023 is provided at the other end of the fixed plate 3021. The circular ring 3023 is rotatably installed in the ring groove 3013;

[0028] Specifically, Figure 2 As shown, through the cooperation between the annular groove 3013 and the circular ring 3023, the movable plate 3011 and the fixed plate 3021 can rotate, thereby improving the flexibility of the device.

[0029] Furthermore, a limiting groove 3014 is provided in the annular groove 3013, and a limiting block 3024 is fixedly installed on one side of the circular ring 3023, and the limiting block 3024 is arranged corresponding to the limiting groove 3014;

[0030] Specifically, Figures 2 to 4 As shown, when the circular ring 3023 rotates in the annular groove 3013, each set of limit blocks 3024 will first rotate from the starting position to the next set of limit grooves 3014, and start a certain limit to prevent excessive flexibility from causing inconvenience in use, thereby achieving the effect of improving the limit.

[0031] It should be noted that the limit block 3024 is made of soft material, so a large force is required when rotating to avoid deviation after rotation adjustment, which causes the limit component 303 to be unable to limit the fixed plate 3021 and the movable plate 3011.

[0032] Further, the limiting component 303 includes a limiting plate 3031, which is movably installed on one side of the fixed plate 3021, and a plurality of groups of clamping rods 3032 are equidistantly arranged on one side of the limiting plate 3031, a plurality of groups of through holes 3022 are provided on one side of the fixed plate 3021, and a plurality of groups of docking holes 3012 are provided on one side of the movable plate 3011, and the through holes 3022 and the docking holes 3012 are arranged corresponding to the clamping rods 3032;

[0033] Specifically, Figures 2 to 4 As shown, after the fixed plate 3021 and the movable plate 3011 are adjusted, the limiting plate 3031 is slid to one end so that the clamping rod 3032 is inserted into the through hole 3022 and the docking hole 3012 to limit the two and make them unable to move, thereby achieving the effect of convenient limiting and fixing after adjustment.

[0034] It should be noted that the positions of the through holes 3022 and the docking holes 3012 are relative to the positions of the limiting grooves 3014 . When the limiting blocks 3024 move toward the next group of limiting grooves 3014 , the docking holes 3012 will also move into the next group of through holes 3022 .

[0035] Furthermore, a return spring 3033 is disposed on the outer surface of the clamp rod 3032, one end of the return spring 3033 is disposed on one side of the limiting plate 3031, and the other end of the return spring 3033 is disposed on one side of the fixing plate 3021;

[0036] Specifically, Figure 4 As shown, when the limit plate 3031 is not subjected to force, the characteristics of the return spring 3033 will drive the limit plate 3031 to slide, so that the clamping rod 3032 is inserted into the docking hole 3012 and the through hole 3022, thereby improving the convenience of use.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
