DETAILED DESCRIPTION
[0020] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model and does not strictly limit the specific protection scope requested by the utility model.
[0021] As Figure 1 shown, a kind of classification of electroencephalogram thread prevents winding device, including multiple winding units, multiple winding units are divided into at least two types, winding unit includes shell, the shell color of different types of winding unit is different, when winding unit is completed to electroencephalogram thread winding, by observing the color of shell, the kind of electroencephalogram thread can be determined, simultaneously, by winding unit to electroencephalogram thread winding, the phenomenon that electroencephalogram thread can be reduced because of being too long and being mutually wound.
[0022] Among them, if winding unit is divided into two categories, the color of the shell of two kinds of winding units is red and green respectively.
[0023] The technical scheme is as Figures 1-2 shown, the winding mechanism is improved, and specifically, two threading holes 3 are formed in the shell, a first rotating handle 4 is rotatably connected to the outer side of the shell, a core column 5 is rotatably connected to the inside of the shell and in transmission connection with the first rotating handle 4, and a pay-off slot 6 is formed in the core column 5. At this time, the electroencephalogram thread can be inserted into the pay-off slot 6 through the threading hole 3, and then threaded out through the other threading hole 3. A plurality of elastic extension arms are arranged on the core column 5, and each of the plurality of elastic extension arms is provided with a positioning block. By rotating the first rotating handle 4, the plurality of positioning blocks can be driven to revolve, so that the electroencephalogram thread can be wound around the combination of the plurality of positioning blocks outside for winding. When in use, if the electroencephalogram thread is subjected to tension due to external force, the elastic extension arms can automatically exert a pushing force on the positioning blocks to make them contract towards the core column 5, so that the combination of the plurality of positioning blocks contracts, a certain space is left for the wound part of the electroencephalogram thread, and the wound part of the electroencephalogram thread can extend outward by a certain length again, so as to buffer the tension on the electroencephalogram thread and reduce the phenomenon that the end of the electroencephalogram thread is detached or damaged due to excessive tension. After the tension on the electroencephalogram thread disappears, the elastic extension arms automatically drive the positioning blocks to reset, and the part of the electroencephalogram thread that extends outward is wound again.
[0024] The elastic extension arm includes a sliding arm 10 and a return spring 11. The core column 5 has multiple cavities 17 arranged in a ring. The sliding arm 10 is slidably connected inside the cavity 17, and one end of the sliding arm 10 is located outside the core column 5 and fixedly connected to the positioning block. The return spring 11 is fixedly connected inside the cavity 17 and located on the side of the sliding arm 10 away from the positioning block. At this time, under the elastic force of the return spring 11, the sliding arm 10 can be automatically pushed outward, and the sliding arm 10 can be retracted under force.
[0025] like Figures 2-4 As shown, in order to adjust the elasticity of the return spring 11 applied to the EEG lines, a movable pressure plate 16 is provided inside the cavity 17. The return spring 11 is fixedly connected between the slide arm 10 and the pressure plate 16. By adjusting the position of the pressure plate 16, the elasticity of the return spring 11 can be adjusted. In order to control the position of the pressure plate 16, this technical solution has a movable adjustment group installed on the core column 5 and drivenly connected to the pressure plate 16. The movable adjustment group can be an electromagnetic adjustment group composed of magnets and electromagnets, or a mechanical adjustment group. In this technical solution, a mechanical adjustment group is preferred. Specifically, a threaded rod 15 is rotatably connected to the core column 5 and threadedly connected to the pressure plate 16. By rotating the threaded rod 15, the position of the pressure plate 16 can be adjusted and locked after adjustment.
[0026] Meanwhile, a second rotating handle 12 can be rotatably connected to the housing. A first bevel gear 13 is fixedly connected to the second rotating handle 12. A second bevel gear 14 that meshes with the first bevel gear 13 is fixedly connected to the end of the threaded rod 15. By rotating the second rotating handle 12, the threaded rod 15 can be rotated through the transmission of the first bevel gear 13 and the second bevel gear 14, thereby making it relatively easy to rotate the threaded rod 15 and adjust the position of the pressure plate 16.
[0027] Specifically, the positioning block includes a U-shaped frame 7 fixedly connected to the slide arm 10, and a rotating drum 8 is rotatably connected to the U-shaped frame 7. In use, the EEG line is wound up on the outside of multiple rotating drums 8. When the EEG line is pulled by force, the rotation of the rotating drum 8 can reduce the friction force on the EEG line.
[0028] like Figures 1-3As shown, the shell includes a main winding box 1 and a detachable box cover plate 2 fixedly connected to the shell, which can be clamped, magnetically attracted or other ways, the technical solution is provided with a threading hole 3 on the main winding box 1, a second rotating handle 12 is rotatably connected to the main winding box 1, a core column 5 is rotatably connected to the second rotating handle 12, then a first rotating handle 4 is rotatably connected to the box cover plate 2, the first rotating handle 4 is fixedly connected with a transmission block 9, the transmission block 9 can be clamped in the inside of the pay-off groove 6, so as to complete the transmission of the first rotating handle 4 and the core column 5, which can be relatively simple to disassemble and assemble the shell, and is convenient to maintain the internal structure of the shell.
[0029] The above is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the technical field, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
