DETAILED DESCRIPTION

[0028] The application will be further described below in conjunction with the drawings and embodiments.

[0029] Please refer to Figures 1 to 8 A brain electrical activity mapping electrode cap convenient to disassemble and position includes: a cap shell 1, a side cap along 11 is arranged at the lower end of the cap shell 1, a built-in soft layer 2 is arranged in the cap shell 1, a plurality of electrode pieces 21 are arranged on the built-in soft layer 2, and a cap-shaped pressure bag 3 is arranged between the cap shell 1 and the built-in soft layer 2; a multi-point positioning mechanism, the multi-point positioning mechanism includes a top insert 4, the top insert 4 is fixedly connected with the top position of the built-in soft layer 2, an opposite insert cylinder 41 is arranged at the top position of the cap shell 1, a butt joint ring 42 is arranged at the top position of the cap-shaped pressure bag 3, a side lock pipe 43 is fixedly connected to the side wall of the opposite insert cylinder 41, a clamping groove is arranged on the side wall of the top insert 4, a pre-self-locking assembly is arranged in the side lock pipe 43, and a double-sided reinforcing assembly is arranged between the built-in soft layer 2 and the cap shell 1.

[0030] In the implementation process, as shown in Figure 2 and Figure 3 The inside of the opposite sleeve 41 is provided with a square positioning slot 411, and the top plug-in part 4 is a square plug rod. The top plug-in part 4 is in sliding connection with the square positioning slot 411.

[0031] It should be noted that during installation, the built-in soft layer 2 is first placed in the inside of the cap shell 1, and at the same time, the top plug-in part 4 (square plug rod) at the top position is slid into the square positioning slot 411 in the inside of the opposite sleeve 41 at the top position of the cap shell 1. The preliminary positioning of the top is completed by the limiting effect of the square structure, and the automatic locking is realized during the insertion process, thereby ensuring the stability of the installation.

[0032] The positioning and cooperation of the square structure can effectively prevent the top plug-in part 4 from rotating in the opposite sleeve 41, and ensure that the relative positions of the top of the built-in soft layer 2 and the top of the cap shell 1 are accurately aligned, thereby providing a basic positioning for the subsequent detection of the corresponding head of the electrode part 21.

[0033] Referring to Figure 3 and Figure 6 The pre-self-locking assembly includes a lock rod 5, the lock rod 5 is in sliding connection with the inside of the side lock pipe 43, the lock rod 5 is fixedly connected with an embedded plate 51, the embedded plate 51 is arranged in the inside of the side lock pipe 43, the lock rod 5 is connected with a spring 52 in a sleeved manner, one end of the spring 52 is connected with the embedded plate 51, the other end of the spring 52 is connected with the inner wall of the side lock pipe 43, one end of the lock rod 5 is fixedly connected with a clamping head 53, and the other end of the lock rod 5 is fixedly connected with a pull ring 54. The clamping head 53 is designed in a wedge shape.

[0034] It should be noted that during the insertion process, the inclined surface of the clamping head 53 at one end of the lock rod 5 abuts against the side wall of the top plug-in part 4, so that the lock rod 5 is driven to slide relative to the side lock pipe 43, and the spring 52 is elastically deformed.

[0035] Until the insertion is completed, at this time, the clamping head 53 and the clamping groove position are coincided with each other, the spring 52 restores the elastic deformation, the lock rod 5 drives the wedge-shaped clamping head 53 to be automatically reset and clamped into the clamping groove on the side wall of the top plug-in part 4, and the pre-self-locking is realized.

[0036] The embedded plate 51 can not only limit the sliding stroke of the lock rod 5 to prevent it from falling out of the side lock pipe 43, but also serve as a force fulcrum of the spring 52 to ensure that the elastic potential energy of the spring 52 stably acts on the lock rod 5.

[0037] The pull ring 54 provides a convenient force point for disassembly, and the self-locking state can be quickly released by manually pulling, thereby realizing the efficient operation of “automatic locking during installation and manual unlocking during disassembly”.

[0038] Referring toFigure 2 And Figure 5 As shown in FIG. 1, the inner wall of the cap shell 1 is provided with an embedded cap groove 12, and the cap-shaped pressurizing capsule 3 is fixedly installed inside the embedded cap groove 12.

[0039] It should be noted that the embedded cap groove 12 provides a stable installation space for the cap-shaped pressurizing capsule 3, which can limit the positional deviation of the pressurizing capsule during inflation and deflation, and ensure that the pressure is uniformly applied to the corresponding area of the built-in soft layer 2.

[0040] At the same time, the fixed connection mode of the cap-shaped pressurizing capsule 3 and the cap shell 1 avoids the relative sliding between the capsule and the shell during the pressurizing process, further ensuring the stability of the electrode piece 21.

[0041] Referring to FIG. 2, Figure 1 And Figure 4 As shown in FIG. 2, the bilateral reinforcing assembly includes two side right-angle frames 6, both of which are fixedly connected with the two side walls of the built-in soft layer 2. Both of the two side right-angle frames 6 are fixedly connected with a latch 61, both sides of the side cap 11 are provided with a side ear seat 62, both of the two side ear seats 62 are provided with a side insertion slot 63, and the two latches 61 are respectively connected with the two side insertion slots 63 in a sliding manner. Both of the two side ear seats 62 are slidably connected with a transversely placed insertion rod 64, and both of the two latches 61 are provided with a positioning slot.

[0042] It should be noted that the bilateral symmetric reinforcing structure can balance the stress on both sides of the built-in soft layer 2. The sliding cooperation between the latch 61 and the side insertion slot 63 provides a guiding effect for bilateral positioning, and the engagement between the transversely placed insertion rod 64 and the positioning slot can firmly lock the latch 61 in the side insertion slot 63, forming a double guarantee of insertion guidance and locking fixation, and realizing three-point stable support in cooperation with the top positioning structure.

[0043] Referring to FIG. 3, Figure 4 As shown in FIG. 3, the side wall of the side ear seat 62 is fixedly connected with a folding plate 65, the folding plate 65 is fixedly connected with a short horizontal rod 66, the short horizontal rod 66 is slidably connected with a special-shaped push plate 67, one end of the transversely placed insertion rod 64 is fixedly connected with the special-shaped push plate 67, the folding plate 65 is rotatably connected with an adjusting shaft 68, one end of the adjusting shaft 68 is fixedly connected with a main handle 69, the adjusting shaft 68 is a threaded rod, the special-shaped push plate 67 is provided with a threaded hole, and the special-shaped push plate 67 is threadedly connected with the adjusting shaft 68.

[0044] It should be noted that the threaded rod design of the adjusting shaft 68 converts the rotary motion into the linear motion of the special-shaped push plate 67, and cooperates with the guiding effect of the short horizontal rod 66 on the special-shaped push plate 67 to accurately control the extension and retraction stroke of the transversely placed insertion rod 64.

[0045] The main handle 69 is provided to increase the hand force point, making the operation more labor-saving.

[0046] Referring to FIG. 4,Figure 2 And Figure 7 As shown in the figure, the hat-shaped compression capsule 3 is provided with a uniform compression mechanism between the side cap edge 11, the side wall of the side cylinder tube 7 is fixedly connected with the side cap edge 11, the lower end of the side cylinder tube 7 is fixedly connected with the delivery pipe 71, the other end of the delivery pipe 71 is connected with the hat-shaped compression capsule 3, the upper end of the side cylinder tube 7 is slidably connected with the piston rod 72, one end of the piston rod 72 is fixedly connected with the built-in piston 73, the top end of the piston rod 72 is fixedly connected with the long strip plate 8, the side wall of the side cylinder tube 7 is fixedly connected with the rear frame 81, the vertical shaft 82 is rotatably connected in the rear frame 81, and the vice handle 83 is connected to the top end of the vertical shaft 82.

[0047] It should be noted that: the side cylinder tube 7, the delivery pipe 71 and the hat-shaped compression capsule 3 form a closed gas delivery space, which ensures that the gas can be delivered to the hat-shaped compression capsule 3, and the internal pressure of the hat-shaped compression capsule 3 increases, so that the built-in soft layer 2 can be compressed, so that the multiple electrode pieces 21 on the built-in soft layer 2 can be closely attached to the head, avoiding signal interference or detection data distortion caused by poor fit, and the compression force can be flexibly adjusted according to the head condition of different users, and different head shapes can be adapted.

[0048] Reference Figure 1 And Figure 7 As shown in the figure, the vertical shaft 82 is a threaded rod, one end of the long strip plate 8 is provided with a threaded port, one end of the long strip plate 8 is threadedly connected with the vertical shaft 82, and the rear frame 81 is provided with a long strip port, and one end of the long strip plate 8 is slidably connected with the long strip port.

[0049] It should be noted that: the vertical shaft 82 is a threaded rod, which is matched with the threaded port at one end of the long strip plate 8, has a self-locking characteristic, and can stably maintain the position of the piston rod 72 after adjustment, avoiding the change of the pressure caused by external force or gas pressure reaction force;

[0050] The sliding cooperation of the long strip plate 8 and the long strip port limits the movement track of the long strip plate 8, ensures that it can only move in the vertical direction, thereby driving the piston rod 72 to stably ascend and descend, avoiding the problem of poor gas pressure adjustment caused by the inclination of the piston rod 72, and ensuring the stability and accuracy of the pressure adjustment in the hat-shaped compression capsule 3.

[0051] The working principle of the electroencephalogram electrode cap convenient to disassemble and position provided by the application is as follows: during installation, the built-in soft layer 2 is placed in the inside of the cap shell 1 in advance, and the top plug-in part 4 (square plug rod) at the top position thereof is slid into the square positioning slot 411 in the inside of the opposite plug-in barrel 41 at the top position of the cap shell 1, and the preliminary positioning of the top is completed by using the limiting action of the square structure; during the insertion process, the inclined surface of the clamping head 53 at one end of the lock rod 5 abuts against the side wall of the top plug-in part 4, so that the lock rod 5 is driven to slide relative to the side lock tube 43, and the spring 52 is elastically deformed, until the insertion is completed, at which time the clamping head 53 and the clamping groove position coincide with each other, the spring 52 restores the elastic deformation, the lock rod 5 drives the wedge-shaped clamping head 53 to be automatically reversely reset and clamped into the clamping groove on the side wall of the top plug-in part 4, pre-self-locking is realized, and the position deviation during installation is avoided.

[0052] Meanwhile, the side right-angle frames 6 on both sides of the built-in soft layer 2 drive the plug-in pins 61 to slide into the insertion slots in the side ear seats 62 on both sides of the side cap edge 11, the main rotating handle 69 is rotated in sequence, the adjusting shaft 68 is driven to rotate, the special-shaped push plate 67 is driven to move the horizontally-placed plug-in rod 64, until the end head thereof slides into the opposite slot on the plug-in pin 61, the locking of the secondary positioning is realized by using the double-side reinforcing assembly, the multi-point fixing structure of “top and double sides” is formed, the disassembly process of the electrode cap can be greatly simplified under the condition that the installation is completed and very close, whether the quick replacement in daily detection or the cleaning and maintenance in the later period, the operation time can be saved.

[0053] During disassembly, the lock rod 5 is slid out of the clamping groove only by pulling the pull ring 54 of the side lock tube 43, and the horizontally-placed plug-in rod 64 is extracted by reversely rotating the adjusting shaft 68, so that the top plug-in part 4 can be quickly extracted from the opposite plug-in barrel 41, and the tool-free quick disassembly is realized.

[0054] In the aspect of pressurized fitting, the cap-shaped pressurizing capsule 3 is installed between the cap shell 1 and the built-in soft layer 2, and is fixed in the inlaid cap groove 12 of the cap shell 1 by means of the controllable pressure adjusting structure of the cap-shaped pressurizing capsule 3. The cooperation between the top abutment ring 42 of the cap-shaped pressurizing capsule 3 and the top plug-in part 4 can ensure the position stability during pressurization. After wearing, if pressurization is needed, only the sub-turning handle 83 needs to be rotated to drive the vertical shaft 82 (screw rod) to rotate. The long strip plate 8 connected with the vertical shaft 82 screw threadedly moves downward along the long strip opening in the rear frame 81, pushes the piston rod 72 to slide relative to the upper end wall of the side cylinder tube 7, drives the built-in piston 73 to move downward, increases the negative pressure in the side cylinder tube 7, and makes the gas in the side cylinder tube 7 enter the cap-shaped pressurizing capsule 3 through the delivery tube 71. The increase of the gas pressure in the cap-shaped pressurizing capsule 3 can press the built-in soft layer 2, so that the multiple electrode parts 21 on the built-in soft layer 2 can be closely fitted to the head, avoid signal interference or detection data distortion caused by loose fitting, and can also flexibly adjust the pressing force according to the head conditions of different users, adapt to different head shapes, and further improve the detection reliability, which can not only ensure the signal stability during detection, but also avoid the discomfort caused by excessive compression.

Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is based on the content of the specification and drawings of the present application, is also included in the patent protection scope of the present application.
