Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] The core of this utility model is to provide a quick-release structure for a microwave therapy device. The arm fixing head is snapped together with the limiting plate, and the relative position of the limiting plate and the arm fixing head can be adjusted to lock or unlock the arm fixing head, which facilitates the disassembly and assembly process of the arm and is beneficial to the packaging and transportation of the microwave therapy device.

[0036] The quick-release structure of the microwave therapy device provided by this utility model includes a head 10, a support arm 20 and a radiator 30. The head 10 is provided with a support arm base 13. The support arm fixing head 21 of the support arm 20 is installed in the support arm mounting hole 1321 of the support arm base 13. The support arm base 13 is provided with a limiting plate 133 for engaging with the support arm fixing head 21, and a horizontal adjustment component for adjusting the relative position of the limiting plate 133 relative to the support arm mounting hole 1321.

[0037] When the horizontal adjustment component moves the limit plate 133 to the locked position, the support arm fixing head 21 engages with the limit plate 133 to lock the support arm 20. When the horizontal adjustment component moves the limit plate 133 to the unlocked position, the limit plate 133 disengages from the support arm fixing head 21 to unlock the support arm 20.

[0038] Please refer to Figure 1 The outrigger base 13 is mounted on the side of the machine head 10. The outrigger base 13 and the machine head 10 can be assembled using common detachable connection methods such as bolts or pins. Compared to welding or integrated structure designs, this method is easier to manufacture. For example, please refer to... Figure 7 and Figure 8Fasteners such as bolts and connecting pins pass through the mounting holes of the base body 132 and the mounting holes 1311 of the base plate 131 in sequence and connect to the upper shell 12 of the machine head 10.

[0039] The arm fixing head 21 of the arm 20 is installed inside the arm base 13. The arm base 13 can be snapped into the limiting plate 133 inside the arm base 13, thereby fixing the position of the arm fixing head 21 and locking the arm 20 to prevent the arm 20 from coming out of the arm base 13, thus ensuring the normal operation of the microwave therapy device. The arm fixing head 21 and the limiting plate 133 can be snapped together through limiting grooves, hooks, buckles, etc.

[0040] To facilitate the disassembly of the support arm 20, a horizontal adjustment component is provided in the support arm base 13. The horizontal adjustment component is used to adjust the position of the limiting plate 133 to change the engagement state between the limiting plate 133 and the support arm fixing head 21, thereby realizing the locking and unlocking of the support arm 20. Considering that the path of rotation of the limiting plate 133 relative to the support arm fixing head 21 is difficult to avoid interference with the support arm fixing head 21, the horizontal adjustment component usually drives the limiting plate 133 to move relative to the support arm fixing head 21 by translation.

[0041] The horizontal adjustment component can be configured as a mechanical mechanism such as a guide rail slider mechanism or a screw mechanism, which drives the movement of the limit plate 133 manually, or it can be configured as an electric push rod, which controls the movement of the limit plate 133 automatically, thus simplifying the loading and unloading process of the support arm base 13.

[0042] In this embodiment, the arm fixing head 21 is snapped into the arm base 13. The limiting plate 133 is moved to the unlocking position by the horizontal adjustment component to unlock and disassemble the arm 20. Compared with the existing bolt fixing method, this method facilitates the disassembly of the arm 20 and is beneficial for the packaging and transportation of the microwave therapy device.

[0043] Based on the above embodiments, the snap-fit ​​method of the limiting plate 133 and the support arm fixing head 21 is defined. The bottom of the support arm fixing head 21 is provided with an annular limiting groove 211, and the outer edge of the limiting plate 133 is provided with an arc-shaped limiting groove 1331 for snap-fitting with the annular limiting groove 211. The radius of the arc-shaped limiting groove 1331 gradually decreases from top to bottom.

[0044] Please refer to Figure 13 The bottom of the outrigger fixing head 21 is provided with an annular limiting groove 211 so that the orientation of the outrigger fixing head 21 affects the snap-fit ​​between the outrigger fixing head 21 and the limiting plate 133.

[0045] The height of the annular limiting groove 211 is greater than or equal to the thickness of the limiting plate 133, and the depth of the annular limiting groove 211 needs to be determined according to the radius difference between the upper and lower ends of the arc-shaped limiting groove 1331, so that the arc-shaped limiting groove 1331 can be effectively engaged in the annular limiting groove 211 of the support arm fixing head 21.

[0046] Please refer to Figure 12 In order to facilitate the locking and unlocking of the limiting plate 133 and the arm fixing head 21, the arc-shaped limiting groove 1331 is provided on the outer edge of the limiting plate 133. The central angle corresponding to the arc-shaped limiting groove 1331 is not limited, but in order to effectively limit the position of the arm fixing head 21, the central angle corresponding to the arc-shaped limiting groove 1331 is usually set to 180°.

[0047] The radius of the arc-shaped limiting groove 1331 gradually decreases from top to bottom. To facilitate processing, the arc-shaped limiting groove 1331 is usually set as a wedge-shaped surface. When the support arm fixing head 21 is pressed and contacts the arc-shaped limiting groove 1331, the wedge-shaped surface makes the downward pressure of the support arm fixing head 21 have a horizontal component, thereby pushing the arc-shaped limiting groove 1331 and the limiting plate 133 to move horizontally, so that the arc-shaped limiting groove 1331 is locked in the annular limiting groove 211 of the support arm fixing head 21.

[0048] When the center of the arc-shaped limiting groove 1331 is located on the axis of the arm mounting hole 1321, the limiting plate 133 is in the locked position. Pressing down the arm fixing head 21 causes the limiting plate 133 to engage with the arm fixing head 21, thereby locking the position of the arm 20. When the center of the arc-shaped limiting groove 1331 is far away from the axis of the arm mounting hole 1321, the limiting plate 133 is in the unlocked position. The limiting plate 133 is disengaged from the arm fixing head 21, making it easy to pull the arm fixing head 21 upward and unlock the arm 20.

[0049] In this embodiment, the annular limiting groove 211 of the outrigger fixing head 21 engages with the arc-shaped limiting groove 1331 on the outer edge of the limiting plate 133. The structure is simple and easy to process and assemble. At the same time, the setting of the annular limiting groove 211 enables the outrigger fixing head 21 to be effectively engaged with the limiting plate 133 in all directions, which facilitates the installation, locking and unlocking of the outrigger fixing head 21.

[0050] Preferably, at least one guide post 1322 can be provided in the support arm base 13, and at least one guide groove 1332 can be provided in the limiting plate 133. The guide post 1322 is slidably installed in the guide groove 1332. The horizontal movement direction of the limiting plate 133 is limited by the sliding cooperation between the guide post 1322 and the guide groove 1332, so as to prevent the limiting plate 133 from moving when the horizontal adjustment component drives the limiting plate 133 to move.

[0051] Based on the above embodiments, the horizontal adjustment assembly may include an adjustment rod 1342 and a spring 1343. The axial direction of the adjustment rod 1342 is parallel to the extension direction of the guide groove 1332. The adjustment rod 1342 is installed in the threaded hole 1333 of the limiting plate 133. The spring 1343 is sleeved on the outside of the adjustment rod 1342. One end of the spring 1343 is connected to the limiting plate 133, and the other end is connected to the inner wall surface of the support arm base 13.

[0052] Please refer to Figure 8 The adjusting rod 1342 is provided with external threads. The adjusting rod 1342 is threadedly installed in the threaded hole 1333 of the vertical mounting plate of the limiting plate 133. The axial direction of the adjusting rod 1342 is parallel to the extension direction of the guide groove 1332, so as to ensure that the direction of the pulling or pushing force of the adjusting rod 1342 on the limiting plate 133 is parallel to the extension direction of the guide groove 1332, and to avoid the guide post 1322 and the guide groove 1332 getting stuck during the horizontal movement of the limiting plate 133.

[0053] A spring 1343 is provided between the limiting plate 133 and the inner wall surface of the support arm base 13. To facilitate the assembly of the spring 1343, it is usually connected to the base plate 131 of the support arm base 13, rather than to the inner wall surface of the base body 132; please refer to Figure 9 One end of the spring 1343 is welded or snapped to the vertical mounting plate of the limiting plate 133, and the other end of the spring 1343 is snapped into the spring fixing groove 1312 of the base plate 131.

[0054] When locking the support arm 20, first turn the adjusting rod 1342 outward to move the limiting plate 133 outward along the axial direction of the adjusting rod 1342, so that the center of the arc-shaped limiting groove 1331 of the limiting plate 133 is located on the axis of the support arm mounting hole 1321. Then press down to fix the support arm head 21 until the arc-shaped limiting groove 1331 reaches the height of the annular limiting groove 211. Under the action of the spring 1343, the arc-shaped limiting groove 1331 of the limiting plate 133 is engaged in the annular limiting groove 211.

[0055] When it is necessary to unlock the support arm 20, first turn the adjusting rod 1342 inward to move the limiting plate 133 inward along the axial direction of the adjusting rod 1342, thereby causing the arc-shaped limiting groove 1331 of the limiting plate 133 to disengage from the annular limiting groove 211 of the fixed support arm head 21, so that the limiting plate 133 loses its limiting effect on the fixed support arm head 21; then pull the fixed support arm head 21 upward to pull the support arm 20 out of the support arm base 13.

[0056] In this embodiment, the threaded connection between the adjusting rod 1342 and the threaded hole 1333 enables both horizontal movement of the limiting plate 133 and convenient fixation of the limiting plate 133 in the horizontal plane. No additional locking parts are required to fix the horizontal position of the limiting plate 133. The structure is simple and the operation is convenient.

[0057] Meanwhile, the spring 1343 between the limiting plate 133 and the base body 132 can press the arc-shaped limiting groove 1331 of the limiting plate 133 against the bottom of the annular limiting groove 211 of the support arm fixing head 21, ensuring the locking and limiting effect of the limiting plate 133 and the support arm fixing head 21.

[0058] Preferably, in order to facilitate the turning of the adjusting rod 1342, the end of the adjusting rod 1342 that is relatively far away from the spring 1343 protrudes from the support arm base 13, and the end of the adjusting rod 1342 that is relatively far away from the spring 1343 is provided with an adjusting knob 1341. The diameter of the adjusting knob 1341 is larger than the diameter of the adjusting rod 1342, so as to reduce the force required to turn the adjusting rod 1342.

[0059] The outer peripheral surface of the adjustment knob 1341 is preferably provided with anti-slip texture. The specific structure, shape and size of the adjustment knob 1341 are determined according to the actual production needs and with reference to the existing technology, and will not be described in detail here.

[0060] Based on the above embodiments, the machine head 10 includes a base 11 and an upper shell 12. In order to facilitate the assembly of the machine head 10, one of the base 11 and the upper shell 12 can be provided with a limiting groove 111, and the other is provided with a limiting block 121 that engages with the limiting groove 111. A locking component for fixing the relative position of the two is provided between the base 11 and the upper shell 12.

[0061] It is understandable that the snap-fit ​​installation direction of the base 11 and the upper shell 12 can be either horizontal, that is, the direction in which the limiting block 121 is inserted into or pulled out of the limiting groove 111 is parallel to the base 11; or vertical or inclined, that is, the direction in which the limiting block 121 is inserted into or pulled out of the limiting groove 111 is perpendicular to or inclined to the base 11.

[0062] The specific shapes of the limiting groove 111 and the limiting block 121 are not limited, as long as they can be engaged. The quantity and distribution of the two are determined according to the structure of the machine head 10 in actual production, so as to ensure that the base 11 and the upper shell 12 can be accurately aligned through the engagement of the limiting groove 111 and the limiting block 121.

[0063] Considering that the base 11 and the upper shell 12 are in surface contact, in order to ensure accurate alignment between the two, a set of snap-fit ​​limiting structures is formed by the snap-fit ​​limiting groove 111 and the limiting block 121. The number of such snap-fit ​​limiting structures should not be less than three sets, and at least one set of snap-fit ​​limiting structures should not be collinear with any other two snap-fit ​​limiting structures.

[0064] Please refer to Figure 2 , Figure 4 and Figure 5 The limiting groove 111 is located on the outer edge of the base 11, and the opening direction of the limiting groove 111 is the same, so that multiple sets of snap-fit ​​limiting structures can be installed at the same time.

[0065] The opening direction of the limiting groove 111 is parallel to that of the base 11, and the limiting groove 111 is a wedge-shaped groove. The wedge-shaped groove can guide the movement of the limiting block 121 and prevent the limiting block 121 from deviating during the movement.

[0066] The locking assembly can be specifically configured as fasteners such as fastening bolts and fixing pins 1121, which are used to limit the relative movement of the base 11 and the upper shell 12 in the aforementioned snap-fit ​​mounting direction.

[0067] In this embodiment, the base 11 and the upper shell 12 are aligned using the snap-fit ​​structure between the limiting groove 111 and the limiting block 121, and the relative positions of the base 11 and the upper shell 12 are fixed using the locking assembly. Compared with the prior art, which uses multiple fastening screws to fix the base 11 and the upper shell 12, the number of locking assemblies required is greatly reduced, which facilitates the disassembly and assembly process of the machine head 10.

[0068] Based on the above embodiments, the locking assembly may include a fixing pin assembly 112. The fixing pin assembly 112 includes a fixing pin 1121 and a positioning groove 122 provided on the bottom surface of the upper shell 12. The fixing pin 112 passes through the fixing pin hole of the base 11 and is installed in the positioning groove 122.

[0069] To facilitate adjustment of the preload of the fixing pin 1121 on the upper shell 12, preferably, a positioning groove 122 can be provided on the wedge-shaped surface. The fixing pin assembly 112 includes an adjusting nut 1122 for adjusting the preload of the fixing pin 1121. The adjusting nut 1122 is connected to the inner surface of the base 11 via an adjusting spring 1123, and the adjusting nut 1122 is threadedly connected to the fixing pin 1121. Figure 3 As shown.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
