Description

Technical Field

[0001] This utility model relates to the field of therapeutic instrument technology, and in particular to an improved electrode head for an ultrasonic therapeutic instrument. Background Technology

[0002] Ultrasonic therapy devices require the use of an electrode head and a patch. First, the patch is applied to the skin, then the electrode head is connected to the patch to begin treatment. Treatment typically involves the electrode emitting radio waves through the patch.

[0003] However, the electrode pads on the electrode heads of current ultrasonic therapy devices are usually directly fixed to the electrode head or installed on the electrode head by bolts. When the electrode pads are damaged and need to be repaired or replaced, it is not possible to quickly remove and replace the electrode pads from the electrode head, which is inconvenient. In order to address this, this utility model provides an improved ultrasonic therapy electrode head. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing an improved electrode head for an ultrasonic therapy device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved electrode head for an ultrasonic therapy device includes: an electrode head body; a handle fixedly mounted on the outside of the electrode head body; an electrode plate detachably mounted on the end of the electrode head body, wherein a protrusion is fixedly mounted on the surface of the electrode plate, a positioning groove is formed on the inner surface of the mounting groove, and the positioning groove is slidably connected to or separated from the protrusion; a mounting groove matching the electrode plate is formed at the end of the electrode head body, a fixing plate is fixedly mounted in the mounting groove, a power socket is fixedly mounted on the bottom of the fixing plate, a plug is inserted into the power socket, and the plug is electrically connected to the electrode plate; and a positioning assembly for fixing the plug to the socket.

[0007] To better achieve the above objectives, the present invention adopts a further technical solution: the positioning component includes two symmetrically sliding blocks that slide through the top of the fixed plate. Each of the moving blocks is movably connected to a rotating frame, and the other end of the rotating frame is hinged to the inner top of the mounting groove. A spring is connected between the opposite sides of the two rotating frames and the top of the fixed plate. A fixed block is fixedly installed at the bottom of each moving block. A positioning block is in contact between the top of each fixed block and the bottom of the fixed plate, and the positioning block is fixedly installed on the surface of the plug. A push rod is in contact with the opposite sides of the two rotating frames. A pressing rod is fixedly installed in the middle of the push rod. The other end of the pressing rod slides through the inner top of the mounting groove and is fixedly installed with a pressing plate.

[0008] To better achieve the above objectives, the present invention adopts a further technical solution: two sliding holes are provided on the top of the fixing plate, and a fixing rod is fixedly installed in each sliding hole, and the two fixing rods slide through the side walls of the two moving blocks respectively.

[0009] To better achieve the above objectives, the present invention adopts a further technical solution: each of the moving blocks has a notch at its top, and the notch is slidably connected to the rotating frame; a fixed shaft slides through each of the notches, and the fixed shaft is fixedly installed at the end of the corresponding rotating frame; and each of the moving blocks has a through hole on its surface, and the through hole is slidably connected to the fixed shaft.

[0010] To better achieve the above objectives, the present invention adopts a further technical solution: the cross-sectional shape of the pressing rod is rectangular.

[0011] The advantages of this invention are: by pushing the pressing plate downwards, the push rod causes the two rotating frames to rotate in opposite directions and compress the springs. Then, by moving the two moving blocks, the fixed blocks can be moved in opposite directions, allowing the electrode sheet to be removed downwards from the mounting slot, thus completing quick disassembly. Conversely, when installing the electrode sheet, after inserting the electrode sheet into the mounting slot, releasing the pressing plate allows the two fixed blocks to move towards each other under the action of the two springs until they are attached to the bottom of the positioning block, thus fixing the two positioning blocks on the fixing plate and completing the quick installation of the electrode sheet. This achieves quick installation and disassembly of the electrode sheet, improving the efficiency of electrode sheet installation and disassembly. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Reference Figures 1 to 4 As shown, an improved electrode head for an ultrasonic therapy device includes: an electrode head body 1 (externally powered); a handle 2, fixedly mounted on the outside of the electrode head body 1; and an electrode plate 3, detachably mounted on the end of the electrode head body 1. The end of the electrode head body 1 has a mounting groove that matches the electrode plate 3. A protrusion 17 is fixedly mounted on the surface of the electrode plate 3. A positioning groove is formed on the inner surface of the mounting groove, and the positioning groove is slidably connected to or separated from the protrusion 17. The sliding engagement between the protrusion 17 and the positioning groove on the mounted electrode plate 3 facilitates the precise alignment of the two subsequent fixing blocks 10 and the positioning block 11. A fixing plate 4 is fixedly mounted inside the mounting groove. A power socket 5 is fixedly installed at the bottom of the fixing plate 4. A plug 6 is inserted into the power socket 5 and is electrically connected to the electrode plate 3. After the electrode plate 3 is installed in the mounting groove, power can be supplied to the electrode plate 3 through the insertion of the plug 6 into the socket 5. A positioning component is used to fix the plug 6 to the socket 5. The positioning component includes two moving blocks 7 that slide symmetrically through the top of the fixing plate 4. Two sliding holes are opened at the top of the fixing plate 4. A fixing rod 18 is fixedly installed in each sliding hole. The two fixing rods 18 slide through the side walls of the two moving blocks 7 respectively, ensuring that the two moving blocks 7 can move radially within the two through holes 16 respectively and cannot deflect.

[0019] Each movable block 7 is movably connected to a rotating frame 8. Each movable block 7 has a notch on its top, and the notch is slidably connected to the rotating frame 8. A fixed shaft 15 slides through each notch and is fixedly installed at the end of the corresponding rotating frame 8. Each movable block 7 has a through hole 16 on its surface, and the through hole 16 is slidably connected to the fixed shaft 15. The other end of the rotating frame 8 is hinged to the top of the mounting groove. When the rotating frame 8 rotates, the movable block 7 can be moved laterally by sliding the fixed shaft 15 in the corresponding through hole 16.

[0020] Springs 9 are connected to the top of the fixed plate 4 on opposite sides of the two rotating frames 8. A fixed block 10 is fixedly installed at the bottom of each moving block 7. A positioning block 11 contacts the bottom of the fixed plate 4 at the top of each fixed block 10. The positioning block 11 is fixedly installed on the surface of the plug 6. Push rods 12 are contacted on opposite sides of the two rotating frames 8. A pressing rod 13 is fixedly installed in the middle of the push rod 12. The other end of the pressing rod 13 slides through the top of the mounting groove and is fixedly installed with a pressing plate 14. The cross-sectional shape of the pressing rod 13 is rectangular. By utilizing the limiting characteristics of the rectangle, the push rod 12 will not deflect in the mounting groove, so as to ensure that both ends of the push rod 12 are always aligned with the two rotating frames 8.

[0021] When using this invention, if it is necessary to disassemble the electrode plate 3, push the pressing plate 14 downwards to cause the pressing rod 13 to drive the push rod 12 downwards, pushing the two rotating frames 8 to rotate in opposite directions and compressing the two springs 9. Then, by using the sliding of the two fixed shafts 15 in the two through holes 16 respectively, the two moving blocks 7 are moved in opposite directions until the two fixed blocks 10 are both away from below the two positioning blocks 11. At this time, the electrode plate 3 can be taken out of the mounting slot downwards, completing the quick disassembly. Conversely, when installing the electrode plate 3, similarly, first push the pressing plate 14 downwards to cause the two fixed blocks 10 to move in opposite directions. Next, align the protrusion 17 on the electrode plate 3 with the positioning groove on the mounting groove and insert it into the mounting groove until the positioning block 11 contacts the fixing plate 4. At this time, the socket 5 and the plug 6 are also connected. Finally, release the pressing plate 14, and under the action of the two springs 9, push the two rotating brackets 8 to rotate in opposite directions, so that the two fixing blocks 10 move in opposite directions until they are attached to the bottom of the positioning block 11. The two positioning blocks 11 can then be fixed on the fixing plate 4, completing the rapid installation of the electrode plate 3. This achieves rapid installation and disassembly of the electrode plate 3 and improves the efficiency of the installation and disassembly of the electrode plate 3.
