Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0028] Embodiment 1: Combined with Figures 1 to 4As shown, the present invention provides a patch-type diaphragm pacemaker, which mainly includes a host 1, a transfer block 3 and an electrode sheet 2. A circuit board is fixed inside the transfer block 3, two large electrode sockets 31 are fixed on the front end face of the transfer block 3, and two small electrode sockets 32 are fixed on the rear end face. The large electrode sockets 31 and the small electrode sockets 32 are both electrically connected to the circuit board, and the large electrode sockets 31 and the small electrode sockets 32 are staggered and arranged in parallel. The electrode sheet 2 is connected to a plug 21 through a cable, and the plugs 21 of the four electrode sheets 2 are correspondingly plugged into the two large electrode sockets 31 and the two small electrode sockets 32. A connector 37 electrically connected to the circuit board is also fixed on one side of the transfer block 3, and the connector 37 is connected to the host 1 through a cable.
[0029] Combination Figures 2 to 6 As shown, the large electrode lock plate 4 is arranged on one side of the large electrode socket 31, and a middle slide plate 41 perpendicular to the large electrode lock plate 4 is fixed in the middle of the large electrode lock plate 4, and the middle slide plate 41 is slidably plugged into the adapter block 3. A clamping seat 7 opposite to the large electrode socket 31 is fixed at each end of the large electrode lock plate 4; when in use, the plugs 21 of the two large electrode sheets 2 are clamped on the clamping seat 7.
[0030] The small electrode lock plate 5 is arranged on one side of the small electrode socket 32, and a side slide plate 51 perpendicular to the small electrode lock plate 5 is fixed at each end of the small electrode lock plate 5, and the side slide plate 51 is slidably inserted in the adapter block 3. Inside the adapter block 3, two side slide plates 51 are arranged in parallel on both sides of the middle slide plate 41. Two clamping seats 7 opposite to the small electrode socket 32 are fixed in the middle of the small electrode lock plate 5; when in use, the plugs 21 of the two small electrode sheets 2 are clamped on the clamping seats 7.
[0031] Inside the adapter block 3, an elastic component 6 is hinged between the middle slide plate 41 and the side slide plate 51; during the relative sliding of the middle slide plate 41 and the side slide plate 51, the direction of the elastic component 6 changes accordingly, so that: when the middle slide plate 41 and the side slide plate 51 are farthest apart, the elastic component 6 is in the pop-up position, and the elastic force of the elastic component 6 at this time pushes the middle slide plate 41 and the side slide plate 51 away from each other; when the middle slide plate 41 and the side slide plate 51 are closest to each other, the elastic component 6 is in the locked position, and the elastic force of the elastic component 6 at this time pushes the middle slide plate 41 and the side slide plate 51 towards each other.
[0032] Working principle: Combination Figure 6 and Figure 7As shown, in the initial state, the elastic component 6 is in the expanded position, and the large electrode locking plate 4 and the small electrode locking plate 5 are away from the adapter block 3. When in use, the plugs 21 of the four electrode plates 2 are snapped onto the corresponding clamping seats 7, and the ends of the plugs 21 are facing or slightly inserted into the corresponding large electrode sockets 31 and small electrode sockets 32. At the same time, the large electrode locking plate 4 and the small electrode locking plate 5 are squeezed inward, driving the plugs 21 to be inserted into the large electrode sockets 31 and small electrode sockets 32, and the elastic component 6 slowly rotates. When the plugs 21 are inserted into the large electrode sockets 31 and small electrode sockets 32, the elastic component 6 is in the locked position, and the elastic component 6 pushes the large electrode locking plate 4 and the small electrode locking plate 5 to move inward and stay, pressing the plugs 21 on both sides to ensure that the electrode plate 2 is in a stable connection state.
[0033] Embodiment 2: Based on the above Embodiment 1, combined with Figures 2 to 7 As shown, in order to ensure the stable sliding of the large electrode locking plate 4 and the small electrode locking plate 5, a sliding groove 33 is provided on the lower side surface of the adapter block 3.

[0034] The middle sliding plate 41 slides through the middle guiding groove 361, and the side sliding plate 51 slides through the side guiding groove 351. In order to prevent the middle sliding plate 41 and the side sliding plate 51 from detaching from the adapter block 3, a rear limiting platform 511 is provided on the inner side edge of the side sliding plate 51, and the rear limiting platform 511 is used to prevent the side sliding plate 51 from sliding out of the side guiding groove 351. Front limiting platforms 411 are provided on both side edges of the middle sliding plate 41, and the front limiting platforms 411 are used to prevent the middle sliding plate 41 from sliding out of the middle guiding groove 361. A bottom plate 34 is fixed to the lower side surface of the adapter block 3 by bolts, and the bottom plate 34 covers the sliding groove 33, the side guiding groove 351 and the middle guiding groove 361, and limits the middle sliding plate 41 and the side sliding plate 51 through the bottom plate 34.
[0035] Two large electrode sockets 31 are arranged on both sides of the middle guiding convex block 36, the large electrode sockets 31 do not extend beyond the front end of the middle guiding convex block 36, and the large electrode sockets 31 are protected between the middle guiding convex block 36 and the large electrode locking plate 4 to prevent being touched. Two small electrode sockets 32 are arranged between the two side guiding convex blocks 35, the small electrode sockets 32 do not extend beyond the rear end of the side guiding convex block 35, and the small electrode sockets 32 are protected between the side guiding convex block 35 and the small electrode locking plate 5 to prevent being touched.
[0036] Combined with Figures 6 to 9As shown, the elastic component 6 includes four elastic push rods 61 arranged in pairs on both sides of the middle slide plate 41. The elastic push rods 61 on each side are parallel to each other, and the elastic push rods 61 on both sides are symmetric about the center line of the middle slide plate 41.
[0037] Both ends of the elastic push rod 61 are hinged to the side edges of the middle slide plate 41 and the side slide plate 51 respectively. Taking the hinge structure of the elastic push rod 61 and the middle slide plate 41 as an example: Hinge columns 611 are fixed at both ends of the elastic push rod 61, and convex portions 612 are provided at the center positions of both ends of the hinge columns 611; a sliding hole 413 is formed at a position near the side edge of the middle slide plate 41, and the sliding hole 413 penetrates the middle slide plate 41 in the thickness direction of the middle slide plate 41; a flared opening 412 is formed at the side edge of the middle slide plate 41, and the inner end of the flared opening 412 communicates with the sliding hole 413, so that the sliding hole 413 forms an open structure, but the perimeter of the sliding hole 413 remains more than half; the hinge column 611 is rotatably installed in the sliding hole 413, and the convex portions 612 at both ends of the hinge column 611 respectively abut against the bottom surface of the sliding groove 33 and the inner side surface of the bottom plate 34, and the end of the elastic push rod 61 is located in the flared opening 412; when the hinge column 611 rotates in the sliding hole 413, the end of the elastic push rod 61 can swing in the flared opening 412 to ensure the smooth rotation of the flared opening 412.
[0038] Working principle: Combining Figure 6 and Figure 7 As shown, when the elastic push rod 61 is in the elastic open position, the end of the elastic push rod 61 connected to the side slide plate 51 is at the rear, and the elastic push rod 61 provides elastic force to push the middle slide plate 41 and the side slide plate 51 away from each other; when the middle slide plate 41 and the side slide plate 51 are pushed inward, the elastic push rod 61 slowly rotates until the end of the elastic push rod 61 connected to the side slide plate 51 is at the front. At this time, the elastic push rod 61 is in the locked position, and the elastic push rod 61 provides elastic force to push the middle slide plate 41 and the side slide plate 51 to keep approaching each other, and presses the plugs 21 on both sides against the large electrode socket 31 and the small electrode socket 32.
[0039] Embodiment 3: On the basis of the above Embodiment 1 or 2, combining Figures 2 to 4 , and Figure 10 As shown, a square column 211 is provided in the middle of the plug 21; limiting steps 212 are respectively provided on both sides of the end of the square column 211, and arc-shaped grooves 213 are provided at the middle positions on both sides of the square column 211.
[0040] Taking a clamping seat 7 at the end of the large electrode locking plate 4 as an example for illustration: The clamping seat 7 includes a pair of clamping platforms 71 fixed on the large electrode locking plate 4. When the plug 21 is clamped onto the clamping seat 7, the clamping platforms 71 just fit on both sides of the square column 211. A positioning stop 711 is provided on one side of the clamping platform 71, and the positioning stop 711 cooperates with the limiting step 212. An elastic piece 72 is fixed on the other side of the clamping platform 71, and the middle of the elastic piece 72 has an arc portion 721. The elastic piece 72 fits on the side surface of the square column 211, and the arc portion 721 is pressed and fitted in the arc groove 213.
[0041] Working principle: As shown in combination with Figure 2 , Figure 6 and Figure 10 , after the plug 21 is clamped onto the clamping seat 7, by pushing the large electrode locking plates 4 and the small electrode locking plates 5 on both sides inward, the plug 21 can be driven to be inserted into the corresponding large electrode socket 31 and small electrode socket 32, and under the thrust of the elastic component 6, it maintains a locked state. When the plug 21 needs to be pulled out, the small electrode locking plate 5 can be pulled outward. After the small electrode locking plate 5 moves away from the adapter block 3, the elastic component 6 rotates, and the large electrode locking plate 4 can be further pushed outward. At this time, the plug 21 of the four electrode plates 2 can be pulled out.
