[0022] In order to make the technical solutions and advantages of the present utility model clearer and more understandable, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0023] The present utility model provides a technical solution: Refer to Figure 1 - Figure 5, a high-frequency electromagnetic short-wave therapeutic apparatus disclosed by the present utility model includes an instrument body 1 and two connecting lines 2. A connecting mechanism 3 is provided between the two connecting lines 2 and the instrument body 1. The connecting mechanism 3 includes two plug bodies 31 and two fixed cylinders 32. The two fixed cylinders 32 are relatively fixedly installed on the front side of the bottom of the instrument body 1. An electric contact block 33 is fixedly installed in the opening at one end of the fixed cylinder 32, and the electric contact block 33 fixedly penetrates through the outer shell of the instrument body 1 and is electrically connected to the output end of the instrument body 1. Two air storage grooves 34 are oppositely opened on the side wall of the plug body 31. An electric contact rod 35 is slidably installed in the air storage groove 34, and one end of the electric contact rod 35 extends outside the plug body 31. A sealing ring 36 is fixedly installed at the other end inside the electric contact rod 35, and the outer ring wall of the sealing ring 36 is in contact with the inner wall of the corresponding air storage groove 34. High-pressure gas is filled in the air storage groove 34 and inside the electric contact rod 35;
[0024] A plugging mechanism 5 is provided inside the fixed cylinder 32, and a limiting mechanism 4 is provided at the other end of the fixed cylinder 32.
[0025] In this embodiment, when assembling the improved high-frequency electromagnetic short-wave therapeutic apparatus, the operator inserts the plug body 31 into the fixed cylinder 32. First, the end of the electric contact rod 35 will first come into contact with the electric contact block 33. And as the plug continues to be inserted into the fixed cylinder 32 and part of the plug body 31 is constrained and limited in the fixed cylinder 32 through the limiting mechanism 4, part of the electric contact rod 35 is pressed into the air storage groove 34 and further compresses the air in the air storage groove 34. At this time, due to the pushing of the gas in the air storage groove 34 on the electric contact rod 35, the electric contact rod 35 is in close fit with the electric contact block 33, thus completing the connection between the connecting line 2 and the instrument body 1;
[0026] During the use of the high-frequency electromagnetic short-wave therapeutic apparatus, if the connecting line 2 is pulled with a large force, the limiting mechanism 4 automatically releases the constrained and limited state between the plug body 31 and the fixed cylinder 32, so that the plug body 31 can directly slide out of the fixed cylinder 32, avoiding the connecting line 2 from being broken due to a great pulling force, or pulling the instrument body 1 off the table, resulting in damage to the instrument body 1. At the same time, the electric contact rod 35 is directly separated from the electric contact block 33, which will not cause damage to the interface or plug of the therapeutic apparatus. Almost no maintenance or replacement of the interface or plug is required, reducing the use cost of the portable high-frequency electromagnetic short-wave therapeutic apparatus, avoiding the connecting line 2 from being broken due to a great pulling force, or pulling the instrument body 1 off the table, resulting in damage to the instrument body 1.
[0027] In a further preferred embodiment of the present utility model, as Figure 4 shown, the inside of the electric contact rod 35 is provided in a hollow shape. The input end of the connecting line 2 is inserted into the corresponding electric contact rod 35 and is in interference fit with the inner wall of the corresponding electric contact rod 35. The connecting line 2 is fixedly connected to the corresponding plug body 31 through bolts;
[0028] In this embodiment, when replacing the connecting wire 2, the operator pulls out the bolt from the plug body 31. Then, the operator inserts the input end of the new connecting wire 2 into the contact rod 35, and makes the inner wall of the input end of the connecting wire 2 closely adhere to the inner wall of the contact rod 35. Subsequently, the connecting wire 2 and the plug body 31 are fixed by the bolt, and the replacement of the connecting wire 2 can be completed. The plug body 31 can be reused.
[0029] In a further preferred embodiment of the present utility model, as Figure 2 , Figure 3 and Figure 5 shown, the limiting mechanism 4 includes two limiting grooves 41, which are oppositely arranged at the other end of the fixed cylinder 32, and the interiors of the two limiting grooves 41 communicate with the interior of the fixed cylinder 32. A soft pad 42 is fixedly installed on the inner wall of the limiting groove 41, and a hemispherical block 45 is fixedly installed on the plug body 31 at a position corresponding to the limiting groove 41;
[0030] In this embodiment, when the above-mentioned connecting wire 2 is subjected to a large pulling force, a great contact force is generated between the hemispherical block 45 and the soft pad 42. As the soft pad 42 shrinks and deforms, the hemispherical block 45 slides out of the limiting groove 41 through the soft pad 42, thereby automatically releasing the connection state between the plug body 31 and the fixed cylinder 32, without the need for the operator to perform other operations or provide additional driving force.
[0031] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 3 shown, two guiding grooves 43 are oppositely arranged at the other end of the fixed cylinder 32, and each guiding groove 43 is located between the corresponding two limiting grooves 41. Two arc-shaped grooves 44 are oppositely arranged on the inner wall of the opening at the other end of the fixed cylinder 32, and the interior of each arc-shaped groove 44 communicates with the interior of the corresponding guiding groove 43 and the interior of the corresponding limiting groove 41;
[0032] In this embodiment, when inserting the plug body 31 into the fixing cylinder 32, the operator first rotates the plug body 31 to align the hemispherical block 45 on the plug body 31 with the guiding groove 43, and then inserts the plug body 31 into the corresponding fixing cylinder 32. At this time, the hemispherical block 45 is inserted into the guiding groove 43 until the hemispherical block 45 abuts against the inner wall of the guiding groove 43. Then the operator twists the plug body 31 until the plug abuts against the inner wall of the limiting groove 41. The operator slowly releases the plug body 31. At this time, due to the pushing of the gas in the installation groove on the plug, part of the hemispherical block 45 is inserted into the soft pad 42, and because the soft pad 42 abuts against the hemispherical block 45, part of the plug body 31 is constrained and limited in the fixing cylinder 32. At this time, the electric shock rod 35 is stably attached to the electric shock block 33, avoiding the hemispherical block 45 from frequently over-extruding the soft pad 42, thereby preventing the reduction of the service life of the soft pad and affecting the use of the device.
[0033] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 5 shown, the plugging mechanism 5 includes an elastic rubber plate 51 with a conical shape, and the inside of the elastic rubber plate 51 is hollow. The elastic rubber plate 51 is arranged in the corresponding fixing cylinder 32, and the outer peripheral wall of the elastic rubber plate 51 is fixedly connected to the inner wall of the corresponding fixing cylinder 32. A plurality of break openings 52 are arranged in a circumferential array at the central position of the soft pad 42;
[0034] In this embodiment, after the above device is used, the operator reversely rotates the plug according to the above method and pulls out the electric shock rod 35 from the fixing cylinder 32. At this time, due to the deformation and reset of the elastic rubber plate 51, the break openings 52 of the elastic rubber plate 51 are closed again, forming a relatively closed space in the fixing cylinder 32, so that external dust will not float into the fixing cylinder 32 along with the air flow and adhere to the electric shock block 33, affecting the use of the device.
[0035] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 5 shown, two limiting rings 53 are fixedly installed on opposite sides of the elastic rubber plate 51, and the two limiting rings 53 are sleeved on the outer peripheral side of the plurality of break openings 52;
[0036] In this embodiment, the setting of the limiting ring 53 can enhance the strength of part of the soft pad 42 and prevent the elastic rubber plate 51 from being torn at the break openings 52, affecting the use of the elastic rubber pad.
[0037] Working principle: When the improved high-frequency electromagnetic short-wave therapeutic apparatus is in use, the operator first rotates the plug body 31 so that the hemispherical block 45 on the plug body 31 aligns with the guiding groove 43, and then inserts the plug body 31 into the corresponding fixed cylinder 32. At this time, the hemispherical block 45 is inserted into the guiding groove 43 until the hemispherical block 45 abuts against the inner wall of the guiding groove 43;
[0038] It should be noted that when the operator inserts the joint body into the fixed cylinder 32, if the hemispherical block 45 is inserted into the limiting groove 41 from the limiting groove 41, due to the mutual abutment of the soft pad 42 and the hemispherical block 45, the operator needs to continuously apply a relatively large force to the plug body 31 to make the hemispherical block 45 pass through the soft pad 42. Inserting the hemispherical block 45 from the position of the guiding groove 43 can avoid the hemispherical block 45 repeatedly over-compressing the soft pad 42, thereby avoiding the reduction of the service life of the soft pad and affecting the use of the device;
[0039] When the above plug body 31 is inserted into the guiding groove 43, the electric shock rod 35 can be synchronously inserted into the guiding groove 43. When the electric shock rod 35 moves in the direction of the soft pad 42, due to the mutual abutment of the electric shock rod 35 and the soft pad 42, the central part of the soft pad 42 opens from the break 52, so that a perforation is formed in the central part of the soft pad 42, enabling the electric shock rod 35 to pass through the soft pad 42. After the electric shock rod 35 contacts the electric shock block 33, due to the mutual abutment of the electric shock rod 35 and the electric shock block 33, part of the electric shock rod 35 retracts into the air storage tank to further compress the gas in the air storage tank. At this time, due to the mutual abutment of the gas inside the air storage tank against the electric shock rod 35, the electric shock rod 35 is in close contact with the electric shock block 33;
[0040] After the above hemispherical block 45 abuts against the inner wall of the guiding groove 43, the operator twists the plug body 31 until the plug abuts against the inner wall of the limiting groove 41. The operator slowly releases the plug body 31. At this time, due to the push of the gas in the air storage tank on the plug, part of the hemispherical block 45 is inserted into the soft pad 42, and due to the mutual abutment of the soft pad 42 and the hemispherical block 45, part of the plug body 31 is restricted and positioned in the fixed cylinder 32. At this time, the electric shock rod 35 is in stable contact with the electric shock block 33;
[0041] It should be noted that when the operator twists the plug body 31, the electric shock rod 35 rotates in contact with the electric shock block 33, so that the contact ends of the electric shock rod 35 and the electric shock block 33 rub against each other, avoiding the occurrence of poor contact between the electric shock rod 35 and the electric shock block 33;
[0042] According to the above steps, the connection between the two plug bodies 31 and the fixed cylinder 32 can complete the assembly between the output end of the high-frequency electromagnetic short-wave therapeutic apparatus and the instrument body 1 of the high-frequency electromagnetic short-wave therapeutic apparatus;
[0043] During the use of the high-frequency electromagnetic short-wave therapeutic apparatus, if the connecting wire 2 is pulled with a large force, a great repulsive force will be generated between the hemispherical block 45 and the soft pad 42. As the soft pad 42 contracts and deforms, the hemispherical block 45 slides out of the soft pad 42 through the limiting groove 41, thereby automatically releasing the connection state between the plug body 31 and the fixed cylinder 32, avoiding the connecting wire 2 from being broken due to a great pulling force, or pulling the instrument body 1 off the table, resulting in damage to the instrument body 1 due to falling;
[0044] After the above device is used up, the operator rotates the plug in the reverse direction according to the above method and pulls out the contact rod 35 from the fixed cylinder 32. At this time, due to the deformation reset of the elastic rubber plate 51, the fracture 52 of the elastic rubber plate 51 is re-closed, forming a relatively closed space in the fixed cylinder 32, so that external dust will not float into the fixed cylinder 32 with the air flow and adhere to the contact block 33, affecting the use of the device.
[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
