[0031] Example 1

[0032] Reference Figure 1 to Figure 7This embodiment provides an electrocardioencephalogram (ECG) machine calibration instrument that is easy to maintain, including:

[0033] The housing 100 has a display screen 101 disposed at a corner of the housing 100, a button slot 103 disposed on the housing 100, and an outer tube 104 disposed at the button slot 103;

[0034] A detachable button 200, comprising a button cap 201, a plug post 202 disposed below the button cap 201, and a collar 204 connected to the button cap 201 via a first spring 203, wherein the collar 204 is sleeved on the outside of the outer tube 104;

[0035] The housing 100 is also provided with a label film 102, which is provided with a plurality of holes 102a, the outer tube 104 is provided in the holes 102a, and the first label 102b and the second label 102c are respectively provided on both sides of the holes 102a;

[0036] A wire insertion hole 105 is disposed on the side of the housing 100 , and the wire insertion hole 105 corresponds to the position of the button slot 103 .

[0037] The label film 102 is set on the surface of the shell by gluing, and its function is not only aesthetic but also identification. A signal source is set inside the shell 100 to generate various signals, which are connected to the signal distribution board through internal electrodes, and then distributed to the wiring terminals at each wiring hole 105 by the signal distribution board. Therefore, each wiring hole 105 is marked as N, R, L, F, C1, C2, C3, C4, C5, and C6 respectively.

[0038] In the present invention, four wire insertion holes 105 N, R, L, and F are arranged on the bottom surface of the housing 100 , and C1 , C2 , C3 , C4 , C5 , and C6 are arranged on the right side of the housing 100 .

[0039] The first label 102b is used to identify the information of the plug hole 105 to facilitate the plugging of the terminal A, and the second label 102c is used to identify the corresponding function of the button.

[0040] During use, the label or label film may be damaged due to friction at the button, and in order to avoid discomfort to the fingertips, a flexible rubber layer is usually provided on the top surface of the button cap. After long-term use, the flexible rubber layer may be scratched or fall off, resulting in missing parts. Therefore, a detachable button is provided to facilitate the replacement of the label film 102 and the button itself. The outer tube 104 is used to fix the detachable button 200, and the outer tube 104 is used to position the installation of the label film 102.

[0041] A ring plate 204 a is provided on the top of the collar 204 . The ring plate 204 a is sleeved on the plug post 202 . Embedding grooves 204 b are provided on both sides of the inner groove of the ring plate 204 a . An inner ring groove 204 c is provided on the inner wall of the collar 204 .

[0042] The first spring 203 connects the ring plate 204 a and the button cap 201 .

[0043] A first side block 202a is disposed near the outer side of the bottom of the plug post 202, and the first side block 202a is embedded in the embedding groove 204b.

[0044] In the initial state, the first spring 203 is not compressed or stretched, and the first side block 202a is correspondingly located in the embedding groove 204b, which is used to maintain the synchronous rotation of the ring 204 and the button cap 201 to ensure that the second side block 202e also corresponds to the position of the embedding groove 204b. When the first spring 203 is compressed and the ring 204 and the button cap 201 undergo axial relative movement, the second side block 202e can also pass through the embedding groove 204b.

[0045] The plug post 202 is provided with a through slot 202b, a horizontal plate 202c is provided in the through slot 202b, a second spring 202d is provided on the horizontal plate 202c and connected to the top of the through slot 202b, and second side blocks 202e are provided at both ends of the horizontal plate 202c.

[0046] The second side block 202e corresponds to the first side block 202a. This structure allows the second side block 202e to have a certain amount of axial movement relative to the plug post 202, and the second spring 202d ensures that the second spring 202d is downward, which is a safety measure to prevent the second side block 202e from getting stuck.

[0047] A vertical groove 103 a is axially arranged inside the button groove 103 , a first arc groove 103 b is arranged on the side of the bottom of the vertical groove 103 a , and a locking groove 103 c is arranged upward at the end of the first arc groove 103 b .

[0048] An oblique pressure groove 103d is obliquely provided at the end of the first arc groove 103b.

[0049] The locking groove 103c is directly opposite to the inclined surface of one side of the oblique pressure groove 103d.

[0050] Specifically, the oblique pressing groove 103d is farther away from the vertical groove 103 as it moves downward, so that the first side block 202a moves downward guided by the oblique pressing groove 103d, thereby preventing the first side block 202a from being dislocated during the pressing process.

[0051] A second arc groove 103e is further provided on the side of the vertical groove 103a, and a side through hole 103f is provided in the second arc groove 103e.

[0052] A rotating plate 103g is rotatably connected to the side through hole 103f, and a stop block 103h is provided inside the rotating plate 103g.

[0053] A slope is provided at one corner of the stopper 103h.

[0054] Specifically, the installation process of the detachable button of the present invention is to put the ring 204 on the outside of the outer tube 104, at this time, press the button cap 201 downward to compress the first spring 203. If the position of the first side block 202a does not correspond to the position of the vertical groove 103a, the button cap 201 is pressed downward while the button cap 201 is rotated. During this process, the first side block 202a is still in the embedding groove 204b, so the plug post 202 rotates together with the button cap 201. When the position of the first side block 202a corresponds to the vertical groove 103a, the first side block 202a moves downward along the vertical groove 103a to the bottom corresponding to the position of the first arc groove 103b. During this process, the second side block 202e also enters the vertical groove 103a and moves to the position corresponding to the second arc groove. Then the button cap is rotated, the first side block enters the first arc groove and the second side block enters the second arc groove. Let go. Under the action of the first spring 203, the button cap moves up, and the top of the first side block is embedded in the locking groove to complete the limit.

[0055] At the same time, when the second side block enters the second arc groove, the second side block squeezes the abutment block to push the rotating plate outwards. The side through hole corresponds to the inner ring groove, so the rotating plate is embedded in the inner ring groove to limit the sleeve ring.

[0056] When the button is used, the button cap is pressed, and the first side block moves downward along the oblique pressure groove, while the second side block remains in the second arc groove.

[0057] The process of removing the button is: slowly press and rotate the button cap in the opposite direction to that during installation. When the first side block 202a corresponds to the first arc groove, the first side block moves along the first arc groove into the vertical groove, and can be removed by pulling it upwards to replace the button and label film.

[0058] Therefore, the button will not be disassembled by mistake when it is used, and it can be disassembled only by slowly pressing and rotating it, so the present invention has strong stability and high convenience.

[0059] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
