Description

Technical Field

[0001] This utility model relates to the field of electroencephalography (EEG) machine technology, and in particular to an improved structure of an EEG machine. Background Technology

[0002] An electroencephalogram (EEG) machine is a device used to record and measure the electrical activity of the human brain. It generates an EEG by placing electrodes on the scalp to detect and record the electrical activity of neurons in the cerebral cortex. However, in existing EEG machines, although the worktable can be adjusted vertically, the adjustment relies on a damping effect for fixation. While this provides some stability, it also prevents the placement of heavy objects. If the force exerted by a heavy object exceeds the damping force, the worktable will shift, causing inconvenience. Therefore, an improved EEG machine structure is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. In conventional EEG machines, although the worktable can be adjusted vertically, the adjustment relies on damping for stability. While this provides a degree of fixation, it also prevents the placement of heavy objects. If the force exerted by a heavy object exceeds the damping force, the worktable will shift, causing inconvenience. Therefore, this invention provides an improved structure for an EEG machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an improved structure for an electroencephalogram (EEG) machine, comprising a support, a sliding groove on one side of the support, a limiting groove on the inner wall of the sliding groove, a block slidably connected to the inner wall of the limiting groove, the outer surface of the block slidably connected to the inner wall of the sliding groove, a support plate fixedly connected to one side of the block, a fixing shell fixedly connected to both sides of the support plate, a rotating rod rotatably connected to the inner wall of the fixing shell, a connecting block fixedly connected to one end of the rotating rod, a locking plate fixedly connected to one side of the connecting block, and locking slots on both sides of the support, the inner wall of the locking slot slidably connected to the outer surface of the locking plate.

[0005] In a preferred embodiment, a torsion spring is provided on the outer surface of the rotating rod, one end of the torsion spring is fixedly connected to the inner wall of the fixed shell, and the other end of the torsion spring is fixedly connected to one side of the connecting block.

[0006] In a preferred embodiment, the inner wall of the limiting groove is provided with a sliding groove, and a slider is slidably connected to the inner wall of the sliding groove.

[0007] In a preferred embodiment, a support rod is fixedly connected to one side of the slider, and a fixing block is fixedly connected to one end of the support rod, with the top of the fixing block being fixedly connected to the bottom of the support plate.

[0008] In a preferred embodiment, a rotating groove is provided on one side of the card plate, and a rotating roller is rotatably connected to the inner wall of the rotating groove.

[0009] In a preferred embodiment, a workbench is fixedly connected to the top of the support plate, and a display screen is fixedly connected to the top of the bracket.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The shape of the block is convex, and the block can be limited by the sliding groove and the limiting groove. The sliding groove makes the block more stable during sliding, while the limiting groove prevents the block from separating from the sliding groove, thereby making the structure of the support plate more stable. At the same time, it also makes the support plate more stable during movement, indirectly making the structure of the worktable more stable. The torsion spring can make the clamping plate tightly attached to the inner wall of the clamping groove through the connecting block, thereby increasing the stability between the clamping plate and the clamping groove. At the same time, controlling the clamping plate to rotate along the center of the rotating rod can separate the clamping plate from the clamping groove, thereby controlling the movement of the support plate, making the structure of the worktable more convenient. At the same time, the clamping plate and the clamping groove can make the worktable withstand greater pressure. The sliding groove can limit the slider, making the slider sliding more stable. At the same time, the slider, support rod and fixing block can support the support plate, increasing the structural stability of the support plate. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: an improved structure for an electroencephalogram (EEG) machine, including a support 1, a sliding groove 2 on one side of the support 1, a limiting groove 3 on the inner wall of the sliding groove 2, a block 5 slidably connected to the inner wall of the limiting groove 3, the outer surface of the block 5 slidably connected to the inner wall of the sliding groove 2, a support plate 9 fixedly connected to one side of the block 5, a fixing shell 10 fixedly connected to both sides of the support plate 9, a rotating rod 11 rotatably connected to the inner wall of the fixing shell 10, a connecting block 13 fixedly connected to one end of the rotating rod 11, a clamping plate 14 fixedly connected to one side of the connecting block 13, a clamping groove 17 on both sides of the support 1, the inner wall of the clamping groove 17 slidably connected to the outer surface of the clamping plate 14, a torsion spring 12 on the outer surface of the rotating rod 11, one end of the torsion spring 12 fixedly connected to the inner wall of the fixing shell 10, and the other end of the torsion spring 12 fixedly connected to one side of the connecting block 13;

[0020] In the above embodiments, the shape of the block 5 is convex. The slide groove 2 and the limiting groove 3 can limit the block 5. The slide groove 2 can make the block 5 more stable during sliding, while the limiting groove 3 can prevent the block 5 from separating from the slide groove 2, thereby making the structure of the support plate 9 more stable. At the same time, it can also make the support plate 9 more stable during movement, indirectly making the structure of the worktable 16 more stable. The torsion spring 12 can make the clamping plate 14 tightly attached to the inner wall of the clamping groove 17 through the connecting block 13, thereby increasing the stability between the clamping plate 14 and the clamping groove 17. At the same time, controlling the clamping plate 14 to rotate along the center of the rotating rod 11 can separate the clamping plate 14 from the clamping groove 17, thereby controlling the movement of the support plate 9, thus making the structure of the worktable 16 more convenient. At the same time, the clamping plate 14 and the clamping groove 17 can make the worktable 16 withstand greater pressure.

[0021] The inner wall of the limiting groove 3 is provided with a sliding groove 4, and a slider 6 is slidably connected to the inner wall of the sliding groove 4;

[0022] A support rod 7 is fixedly connected to one side of the slider 6, and a fixing block 8 is fixedly connected to one end of the support rod 7. The top of the fixing block 8 is fixedly connected to the bottom of the support plate 9.

[0023] Through the above embodiments, the sliding groove 4 can limit the slider 6, making the sliding of the slider 6 more stable. At the same time, the slider 6, the support rod 7 and the fixing block 8 can support the support plate 9, increasing the structural stability of the support plate 9.

[0024] A rotating groove is provided on one side of the card plate 14, and a rotating roller 15 is rotatably connected to the inner wall of the rotating groove;

[0025] A workbench 16 is fixedly connected to the top of the support plate 9, and a display screen 18 is fixedly connected to the top of the bracket 1.

[0026] Through the above embodiments, the rotating roller 15 can first contact the bracket 1, and then in practical applications, the rotating effect of the rotating roller 15 itself can make the card plate 14 move up and down more conveniently.

[0027] Working principle:

[0028] like Figure 1-4 As shown, during use, pressing the clamping plate 14 causes the rotating roller 15 to contact the bracket 1, after which the sliding support plate 9 can be adjusted. Once the position adjustment is complete, the clamping plate 14 rotates back into the clamping groove 17 through the action of the torsion spring 12, thus completing the adjustment. The sliding groove 4 can limit the slider 6, making the sliding of the slider 6 more stable. At the same time, the slider 6, support rod 7, and fixing block 8 can support the support plate 9, increasing the structural stability of the support plate 9. The shape of the block 5 is convex. The sliding groove 2 and the limiting groove 3 can limit the shape of the block 5. The sliding groove 2 can make the block 5 more stable during sliding, while the limiting groove 3 can prevent... The separation of block 5 from the slide groove 2 makes the structure of support plate 9 more stable and also makes support plate 9 more stable during movement, indirectly making the structure of worktable 16 more stable. The torsion spring 12 can make the clamping plate 14 tightly attached to the inner wall of the clamping groove 17 through the connecting block 13, thereby increasing the stability between clamping plate 14 and clamping groove 17. At the same time, controlling the clamping plate 14 to rotate along the center of the rotating rod 11 can separate clamping plate 14 from clamping groove 17, thereby controlling the movement of support plate 9, making the structure of worktable 16 more convenient. At the same time, the clamping plate 14 and clamping groove 17 can make worktable 16 withstand greater pressure.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
