DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 3The embodiment of the utility model provides a power cord that can eliminate entanglement, including a power cord body 1 and a plug part, the plug part includes a fixed cylinder 2 and a rotating cylinder 3, one end of the fixed cylinder 2 is fixedly connected to two pins 4, and the other end is provided with a fixed groove 5 inside, the middle of the top wall of the fixed groove 5 is fixedly connected to a first conductive sheet 6, and the edge of the top wall is fixedly connected to a second conductive sheet 7, the first conductive sheet 6 and the second conductive sheet 7 are respectively electrically connected to the two pins 4, and the electrical connection can be through wire welding, and a channel for the wire to pass through is opened inside the fixed cylinder 2, and the wire can be hidden in the channel. Of course, this is only one embodiment of the electrical connection, and other structures can also be used;

[0020] One end of the rotating cylinder 3 that passes through the fixed groove 5 is fixedly connected to a rotating plate 8, a first conductive needle 9 is fixedly connected to the middle of the upper wall of the rotating plate 8, and a second conductive needle 10 is fixedly connected to the edge of the upper wall. The first conductive needle 9 is in contact with the first conductive sheet 6, and the second conductive needle 10 is in contact with the second conductive sheet 7. The rotating cylinder 3 can rotate in the fixed groove 5. During the rotation process, the first conductive needle 9 and the second conductive needle 10 will also rotate, but because the conductive needle and the conductive sheet are always in sliding contact, they will remain energized;

[0021] It is worth mentioning that the first conductive needle 9 and the first conductive sheet 6 are both located in the middle. No matter how the first conductive needle 9 rotates, they will maintain a sliding contact relationship, thereby maintaining power. In addition, the second conductive sheet 7 is set to be annular. No matter how the first conductive needle 9 rotates, it will slide in contact with the annular area, thereby maintaining power.

[0022] A stop ring 11 is detachably connected to the interior of the fixed groove 5 to prevent the rotating plate 8 from being separated, and the rotating plate 8 is always limited inside the fixed groove 5, thereby ensuring that the first conductive needle 9 and the first conductive sheet 6, and the second conductive needle 10 and the second conductive sheet 7 are in a state of mutual interference;

[0023] The detachable connection method can be: the upper outer wall of the limit ring 11 is threadedly connected to the fixing groove 5. The threaded connection is convenient for disassembly and assembly on the one hand, and on the other hand, by screwing the limit ring 11 upward, the limit ring 11 is pressed upward against the rotating plate 8, driving the first conductive needle 9 and the first conductive sheet 6 to gradually press together, and the second conductive needle 10 and the second conductive sheet 7 to gradually press together, so as to ensure the degree of close contact and the stability of electrical conduction. The lower outer wall of the limit ring 11 is provided with anti-slip grooves 18, which is convenient for holding and driving the limit ring 11 to rotate.

[0024] Furthermore, a radial bearing 14 is embedded in the lower part of the limiting ring 11, and the inner part of the radial bearing 14 is sleeved with the rotating cylinder 3, and the radial bearing 14 bears the radial load of the rotating cylinder 3. An axial bearing 15 is arranged between the upper part of the limiting ring 11 and the lower part of the rotating plate 8, and the axial bearing 15 bears the axial load of the rotating plate 8.

[0025] In summary, since the rotating drum 3 can rotate, it can drive the power cord to rotate to eliminate the twisting force generated when the power cord is entangled, so that the power cord can be laid and straightened faster, and is easier to store and manage, preventing the power cord from being damaged by the twisting force and shortening its service life.

[0026] The front and rear sides of the other end of the rotating cylinder 3 passing through the fixed groove 5 are fixedly connected to two supports 12, and the opposite surfaces of the two supports 12 are rotatably connected to a guide cylinder 13, and the guide cylinder 13 passes through the power cord body 1, and one end of the power cord body 1 is electrically connected to the first conductive needle 9 and the second conductive needle 10 respectively. Since the guide cylinder 13 can be rotated and adjusted relative to the rotating cylinder 3, the outlet angle of the power cord can be adjusted to prevent fatigue or even breakage of the connection between the power cord and the plug when the power cord is pulled or dragged due to the non-adjustable outlet angle.

[0027] When the guide cylinder 13 rotates, the power cord body 1 between the rotating cylinder 3 and the guide cylinder 13 may expand and contract with the rotation, so the interior of the rotating cylinder 3 is configured to be partially hollow to accommodate part of the power cord to adapt to the length change process of the power cord when it expands and contracts.

[0028] Furthermore, sleeve holes 16 are provided on the two supports 12, and sleeve columns 17 are fixedly connected to the front and rear sides of the guide cylinder 13. The sleeve columns 17 are inserted into the sleeve holes 16, so that the guide cylinder 13 can rotate flexibly, and cooperate with the rotation of the rotating cylinder 3, so that the power cord can rotate at multiple angles and in multiple directions, so that when the power cord is plugged in for power supply, there is a more flexible laying route selection according to the space size where the medical instrument is located.

[0029] When the guide cylinder 13 is rotated to be vertical, the limiting ring 11 can be screwed out from the bottom, which is convenient for disassembly, assembly and maintenance.

[0030] It is worth mentioning that one end of the power cord body 1 is electrically connected to the first conductive pin 9 and the second conductive pin 10 respectively by welding a wire, and a channel for the wire to pass through is provided inside the rotating plate 8 and the rotating cylinder 3, and the wire can be hidden in the channel. Of course, this is only one embodiment of the electrical connection, and other structures can also be used;

[0031] Finally, the power cord in the above embodiment is exemplified by two strands of wires - neutral and live wires, but it can also be three strands of wires - three-phase wires, four strands of wires, etc.

[0032] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0033] 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.
