Description

Technical Field

[0001] The utility model belongs to the technical field of infrared irradiation equipment, in particular to a double-head electric lifting control system for an infrared irradiation device. Background Art

[0002] Infrared irradiation devices use infrared radiation for heating or treatment and are widely used in industry, medical care, home use and other aspects. The wavelength range of infrared radiation is relatively narrow, mainly between 3-5μm and 8-14μm. Infrared radiation is focused on one point and can quickly heat objects or act on human tissue.

[0003] In the current existing technology, in order to conveniently adjust the distance between the irradiation surface and the affected surface, most infrared radiation devices set the radiation generator on a lifting structure. However, some infrared radiation devices do not have an effective and stable locking structure. Especially when the lifting drive mechanism fails or there is a power outage, the stable positioning of the radiation generator at the current height cannot be guaranteed, and accidental lifting may occur, resulting in a decrease in the irradiation effect or a safety accident. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the prior art and to propose a double-head electric lifting control system for an infrared irradiation device.

[0005] In order to achieve the purpose of innovation of this utility model, the following technical solutions can be used:

[0006] A double-head electric lifting control system for an infrared irradiation device includes a frame, on which two groups of irradiation components are respectively fixed to a mounting plate, and the mounting plate is slidably connected to a vertical guide column. A lifting drive mechanism is provided between the mounting plate and the frame, and a locking mechanism is provided between the lifting drive mechanism and the frame for limiting the vertical lifting movement of the mounting plate.

[0007] The double-head electric lifting control system of the infrared irradiation device of the present invention is used to realize independent lifting control of two irradiation components to meet the irradiation needs in different application scenarios, wherein the irradiation component includes an infrared radiation source and related control components for generating infrared radiation, which is specifically the existing technology and will not be further elaborated. The mounting plate is the carrier of the irradiation component, which is connected to the vertical guide column by sliding to realize vertical movement. The vertical guide column is used to guide the lifting of the mounting plate to ensure that the mounting plate is stable during the lifting process and does not deviate from the predetermined trajectory. The lifting drive mechanism is used to realize the lifting control of the mounting plate, and the locking mechanism is used to limit the vertical lifting action of the mounting plate when necessary, to ensure the stability of the irradiation component during the irradiation process, to prevent the irradiation effect from being reduced or safety accidents caused by accidental lifting, and generally realize the flexible lifting and stable positioning of the irradiation component.

[0008] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, the lifting drive mechanism includes a driving screw rod vertically arranged on the frame, the driving screw rod passes through the screw rod through-hole of the mounting plate, and the engaging sleeve is provided with a screw rod nut, the screw rod nut and the mounting plate are fixedly connected, and the driving screw rod is connected to the output end of the circumferential driver through the transmission structure.

[0009] The lead screw nut and the driving lead screw are engaged with each other, and the circumferential driver provides driving force to the driving lead screw through the transmission structure, thereby achieving the effect of controlling the lifting and lowering of the lead screw nut. The mounting plate and the lead screw nut are fixedly connected and lifted and lowered synchronously, ensuring the smoothness and accuracy of the lifting and lowering movement of the irradiation component.

[0010] In the above-mentioned double-headed electric lifting control system of the infrared irradiation device, the circumferential drive includes a double-headed motor, and the transmission structure includes a driving wheel fixed on the output end of the double-headed motor, and a driven wheel fixed on the driving screw and meshingly connected with the driving wheel. The driving screw and the driven wheel are symmetrically distributed at both ends of the double-headed motor.

[0011] The double-headed motor has two output ends, which can work independently and can drive the two driving screws to rotate through two transmission structures respectively. The structure is compact. The transmission structure specifically realizes the transmission of driving force through the meshing synchronization between the active wheel and the driven wheel. The transmission efficiency is high and can ensure the smoothness and speed of the lifting movement. The active wheel and the driven wheel are bevel gears, which can realize the conversion and transmission of driving force between the mutually perpendicular double-headed motor output ends and the driving screws.

[0012] In the aforementioned dual-head electric lift control system for an infrared irradiator, the lower end of the drive screw is rotatably connected to the bottom plate of the frame via a screw mounting seat, and the upper end is rotatably connected to the top plate of the frame via a screw positioning seat. The top plate is also provided with an upper through-hole, through which a locking segment is inserted. The locking segment is integrally connected to the upper end of the drive screw, and the locking mechanism is provided between the locking segment and the top plate. While the circumferential drive itself possesses a certain locking capability, the locking mechanism can further enhance locking stability, ensuring locking, particularly in the event of a power outage or drive damage.

[0013] The screw mounting seat is provided on the bottom plate and is used to support the lower end of the driving screw. The screw positioning seat is provided on the top plate and corresponds to the screw mounting seat. It is used to position the upper end of the driving screw, ensuring the stability and reliability of the driving screw. The upper through hole corresponds to the upper end of the driving screw and provides a passage for the locking section to pass through, allowing the locking mechanism to connect or separate with the locking section at the upper end of the driving screw, ensuring that the locking mechanism can smoothly control the rotation limit and limit release of the driving screw through the locking section. In addition, the upper through hole also facilitates the loading and unloading of the driving screw. The screw mounting seat and the screw positioning seat can be connected to the driving screw through bearings, sleeves and other components to achieve rotational connection. This is common knowledge and will not be further elaborated.

[0014] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, the locking mechanism includes a locking gear fixed on the locking section, and a locking block slidably connected to the top plate and located on the side of the locking gear. The locking block is provided with an inwardly concave arc-shaped tooth surface near the locking gear side, and the arc-shaped tooth surface is adapted to the locking gear. A driving assembly is provided between the locking block and the top plate for driving the locking block to move close to or away from the locking gear.

[0015] The locking mechanism achieves locking by meshing a locking gear with an arcuate tooth surface, offering high locking reliability and stability. The locking gear is fixed to the locking segment and rotates with the drive screw. The locking block is slidably connected to the top plate and can move freely horizontally. The drive assembly drives the locking block horizontally, moving it toward or away from the locking gear. When the locking block approaches the locking gear, the arcuate tooth surface meshes with the teeth of the locking gear, locking the lock. When the locking block moves away from the locking gear, the arcuate tooth surface separates from the locking gear, unlocking the lock. Furthermore, the locking structure is located on the top surface of the top plate, facilitating routine maintenance and upkeep.

[0016] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, the driving component includes a double-head electric cylinder, and the two locking blocks are respectively fixed on the output ends of the double-head electric cylinder; a strip-shaped positioning groove is provided on the top plate, and the locking block slides in the positioning groove. The width of the positioning groove is adapted to the width of the locking block, and the length is adapted to the moving path of the locking block.

[0017] The double-head electric cylinder has two independent output ends, which can independently control the movement of the two locking blocks. The positioning groove is used to ensure that the locking block will not shake or deviate from the predetermined path during the sliding process, and has a positioning effect. At the same time, when the arc-shaped tooth surface and the locking gear are engaged and locked, the side of the positioning groove and the side wall of the locking block can provide sufficient force to offset the force of the locking gear to drive the locking block to rotate circumferentially, ensuring the locking effect. In addition, the locking block is simply clamped in the sliding groove, which is easy to disassemble and assemble.

[0018] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, the vertical guide column includes a straight guide section and a U-shaped yielding section. The yielding section is vertically fixed on the bottom plate of the frame with its opening facing downward, and an installation area for setting a circumferential drive is formed between the bottom plate. The guide section is vertically fixed on the top surface of the yielding section, and the guide section passes through the guide sliding hole of the mounting plate.

[0019] The give-way section is U-shaped with its opening facing downward, providing installation space for the circumferential drive. It is equivalent to the give-way section spanning above the circumferential drive, so that the circumferential drive can be compactly installed on the frame. The guide section is straight and vertically connected to the top of the give-way section, providing precise guidance for the lifting and lowering movement of the mounting plate, ensuring that the mounting plate remains vertical and stable during the lifting process.

[0020] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, a lower push switch assembly is also provided on the top surface of the yield section, and the lower push switch assembly is located directly below the mounting plate, and is used to send a signal to the processing end when the mounting plate drops to the bottom; an upper push switch assembly is provided on the bottom surface of the top plate of the frame, and the upper push switch assembly is located directly above the mounting plate, and is used to send a signal to the processing end when the mounting plate rises to the top; the guide section includes an L-shaped main body and a flipping portion hinged to one end of the L-shaped main body, and the flipping portion is used to support upward in a vertical state, and forms a drive disassembly and assembly port when it is opened outward.

[0021] The upper push switch assembly and the lower push switch assembly are respectively located at the upper and lower ends of the mounting plate, which are equivalent to being at the two ends of the moving path of the mounting plate. When the mounting plate descends to the lowest position, it will touch the lower push switch assembly, and when it rises to the highest position, it will touch the upper push switch assembly. The corresponding switch assembly will send a corresponding signal to the processing end, and the processing end will respond accordingly, effectively preventing the mounting plate from damaging related components or causing other safety hazards due to excessive descent or ascent, and ensuring the stable operation of the system. The upper push switch assembly and the lower push switch assembly processing end are existing technologies and will not be elaborated in detail. In addition, the guide section is composed of an L-shaped main body and a flip part, which is equivalent to one side of the U-shaped guide section being able to flip outward. When the flip part is in a vertical state, it and the L-shaped main body together form a complete guide section to ensure a stable support effect. When the flip part is opened outward, a drive disassembly port is formed, providing an opening for the disassembly and assembly of the circumferential drive, achieving flexible disassembly.

[0022] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, a gravity balancing mechanism is provided between the mounting plate and the frame. The gravity balancing mechanism includes a rotating wheel rotatably connected to the bottom surface of the top plate of the frame. A connecting belt is wound around the rotating wheel. One end of the connecting belt is connected to the mounting plate, and the other end is connected to the counterweight block.

[0023] The gravity balancing mechanism reduces the driving load of the lifting drive mechanism by balancing the gravity of the mounting plate and the components thereon. The rotating wheel serves as the support and guide component of the connecting belt. The connecting belt is wound around the rotating wheel to form a closed-loop system. The two ends of the connecting belt are respectively connected to the mounting plate and the counterweight block to achieve gravity balance between the two. When the mounting plate rises, the connecting belt will drive the counterweight block to descend, and vice versa, it will rise, ensuring continuous application of balancing force, effectively reducing the driving load and saving energy consumption.

[0024] In the above-mentioned double-head electric lifting control system of the infrared irradiation device, there are two groups of rotating wheels, one group of which is located directly above the mounting plate, and the other group is located on the side of the mounting plate; connecting rings are fixed at both ends of the connecting belt, and docking hooks are provided on the top surface of the mounting plate and the counterweight block, and the docking hooks and connecting rings are detachably connected; the gravity balancing mechanism is located on the side of the lifting drive mechanism away from the driving screw.

[0025] The design incorporates two sets of rotating wheels, one located directly above and one to the side. The upper rotating wheel ensures that the pulling force on the mounting plate is vertically upward, providing a stable force. The side rotating wheel positions the lifting path of the counterweight block to the side of the mounting plate, preventing interference between the lifting and lowering of the counterweight block and the mounting block. The ends of the connecting belt are connected to the docking hooks on the mounting plate and the counterweight block via connecting rings, providing flexible removability and facilitating adjustment of the counterweight block's weight according to actual needs. Furthermore, the gravity balancing mechanism is located on the side of the lifting drive mechanism away from the drive screw. This helps optimize the overall structure and mechanical performance of the system and reduces the deflection force between the mounting plate and the vertical guide rod.

[0026] Of course, the processing end is electrically connected to the double-head motor, double-head electric cylinder and irradiation component in a wireless or wired manner to control the lifting, switching and height maintenance of the irradiation component.

[0027] As an optimization, a corresponding telescopic arm structure can be provided between the mounting plate and the irradiation assembly to further improve the flexibility of the position control of the irradiation assembly.

In addition, the locking structure is set on the top surface of the top plate, which is convenient for daily maintenance and care.

[0032] 4. The positioning groove is used to ensure that the locking block does not shake or deviate from the predetermined path during the sliding process, and has a positioning effect. At the same time, when the arc-shaped tooth surface and the locking gear are engaged and locked, the side of the positioning groove and the side wall of the locking block can provide sufficient force to offset the force of the locking gear to drive the locking block to rotate circumferentially, ensuring the locking effect.

[0033] 5. The clearance section is U-shaped with the opening facing downward, providing installation space for the circumferential drive. It is equivalent to the clearance section spanning above the circumferential drive, so that the circumferential drive can be compactly installed on the frame.

[0034] 6. The upper push-button switch assembly and the lower push-button switch assembly are located above and below the mounting plate, respectively, effectively preventing the mounting plate from damaging related components or causing other safety hazards due to excessive descent or rise, ensuring stable operation of the system.

[0037] 9. The end of the connecting belt is connected to the mounting plate and the docking hook on the counterweight block through a connecting ring. It has flexible detachability, which makes it easy to adjust the weight of the counterweight block according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0044] Specific implementation examples Figure 1-4 As shown, the double-head electric lifting control system of the infrared irradiation device includes a frame 1, on which two groups of irradiation components 7 are provided. The irradiation components 7 are respectively fixed on a mounting plate 3, and the mounting plate 3 is slidably connected to the vertical guide column 13. A lifting drive mechanism 4 is provided between the mounting plate 3 and the frame 1, and a locking mechanism 5 is provided between the lifting drive mechanism 4 and the frame 1, which is used to limit the vertical lifting movement of the mounting plate 3.

[0045] Specifically, the double-head electric lifting control system of the infrared irradiation device is used to achieve independent lifting control of the two irradiation components 7 to meet the irradiation requirements in different application scenarios. The irradiation component 7 includes an infrared radiation source and its related control components for generating infrared radiation. The mounting plate 3 is the carrier of the irradiation component 7, which is connected to the vertical guide column 13 by sliding to achieve vertical movement. The vertical guide column 13 is used to guide the lifting of the mounting plate 3 to ensure that the mounting plate 3 is stable during the lifting process and does not deviate from the predetermined trajectory. The lifting drive mechanism 4 is used to achieve lifting control of the mounting plate 3, and the locking mechanism 5 is used to limit the vertical lifting movement of the mounting plate 3 when necessary, to ensure the stability of the irradiation component 7 during the irradiation process, to prevent the irradiation effect from being reduced or safety accidents caused by accidental lifting, and generally achieve flexible lifting and stable positioning of the irradiation component 7.

[0046] like Figure 1As shown, the lifting drive mechanism 4 includes a drive screw 41 vertically mounted on the frame 1. The drive screw 41 passes through the screw hole 31 of the mounting plate 3 and is engaged with a screw nut 42. The screw nut 42 is fixedly connected to the mounting plate 3. The drive screw 41 is connected to the output end of the circumferential drive via a transmission structure. The circumferential drive includes a double-headed motor 47. The transmission structure includes a driving pulley 43 fixed to the output end of the double-headed motor 47, and a driven pulley 44 fixed to the drive screw 41 and meshingly connected to the driving pulley 43. The drive screw 41 and the driven pulley 44 are symmetrically distributed at both ends of the double-headed motor 47. The lower end of the driving screw 41 is rotatably connected to the bottom plate 11 of the frame 1 through a screw mounting seat 45, and the upper end is rotatably connected to the top plate 12 of the frame 1 through a screw positioning seat 46. The top plate 12 is also provided with an upper through hole, and a locking section 51 is passed through the upper through hole. The locking section 51 is integrally connected to the upper end of the driving screw 41, and a locking mechanism 5 is provided between the locking section 51 and the top plate 12.

[0047] Specifically, the screw nut 42 and the drive screw 41 mesh with each other, and the circumferential driver provides driving force to the drive screw 41 through the transmission structure, thereby achieving the effect of controlling the lifting and lowering of the screw nut 42. The mounting plate 3 and the screw nut 42 are fixedly connected, and the lifting and lowering are synchronized, ensuring the smoothness and accuracy of the lifting and lowering movement of the irradiation assembly 7. The double-headed motor 47 has two output ends, which can work independently and can respectively drive the two drive screws 41 to rotate through two transmission structures. The structure is compact. The transmission structure specifically transmits the driving force through the meshing and synchronization between the driving wheel 43 and the driven wheel 44. The transmission efficiency is high and can ensure the smoothness and rapidity of the lifting and lowering movement. The driving wheel 43 and the driven wheel 44 use bevel gears to achieve the conversion and transmission of driving force between the mutually perpendicular output ends of the double-headed motor 47 and the drive screw 41. The screw mounting seat 45 is arranged on the base plate 11 for supporting the lower end of the driving screw 41. Specifically, a rotation connection can be achieved through bearings, sleeves and other components. The screw positioning seat 46 is arranged on the top plate 12, corresponding to the screw mounting seat 45, for positioning the upper end of the driving screw 41, ensuring the stability and reliability of the driving screw 41. The rotation connection can also be achieved through bearings, sleeves and other components. The upper through hole corresponds to the upper end of the driving screw 41, providing a passage for the locking section 51, allowing the locking mechanism 5 to be connected or separated from the locking section 51 at the upper end of the driving screw 41, ensuring that the locking mechanism 5 can smoothly control the rotation limit and limit release of the driving screw 41 through the locking section 51. In addition, the upper through hole also facilitates the loading and unloading of the driving screw 41.

[0048] like Figure 1 、 2As shown, the locking mechanism 5 includes a locking gear 52 fixed to the locking section 51, and a locking block 53 slidably connected to the top plate 12 and located to the side of the locking gear 52. The locking block 53 has an inwardly concave arcuate tooth surface 54 near the locking gear 52, and the arcuate tooth surface 54 is adapted to the locking gear 52. A drive assembly is provided between the locking block 53 and the top plate 12 for driving the locking block 53 toward or away from the locking gear 52. The drive assembly includes a double-headed electric cylinder 55, with two locking blocks 53 respectively fixed to the output ends of the double-headed electric cylinder 55; the top plate 12 is provided with a strip-shaped positioning groove 56, in which the locking block 53 slides. The width of the positioning groove 56 is adapted to the width of the locking block 53, and the length is adapted to the movement path of the locking block 53.

[0049] Specifically, the locking mechanism 5 utilizes the meshing of a locking gear 52 and an arcuate tooth surface 54 to achieve locking, providing high locking reliability and stability. The locking gear 52 is fixed to the locking segment 51 and rotates with the drive screw 41. The locking block 53 is slidably connected to the top plate 12 and can freely move horizontally. The drive assembly is used to drive the locking block 53 to move horizontally, moving it closer to or further away from the locking gear 52. When the locking block 53 approaches the locking gear 52, the arcuate tooth surface 54 engages with the teeth of the locking gear 52, achieving locking. When the locking block 53 moves away from the locking gear 52, the arcuate tooth surface 54 separates from the locking gear 52, achieving unlocking. Furthermore, the locking structure is provided on the top surface of the top plate 12, facilitating routine maintenance and upkeep. The double-head electric cylinder 55 has two independent output ends, which can independently control the movement of the two locking blocks 53. The positioning groove 56 is used to ensure that the locking block 53 will not shake or deviate from the predetermined path during the sliding process, and has a positioning effect. At the same time, when the arc-shaped tooth surface 54 and the locking gear 52 are engaged and locked, the side of the positioning groove 56 and the side wall of the locking block 53 can provide sufficient force to offset the force of the locking gear 52 to drive the locking block 53 to rotate circumferentially, thereby ensuring the locking effect. In addition, the locking block 53 is simply clamped in the sliding groove, which is convenient for disassembly and assembly.

[0050] As an optimization of this embodiment, Figure 4As shown, the vertical guide column 13 includes a linear guide section 14 and a U-shaped clearance section 15. The clearance section 15 is vertically fixed on the bottom plate 11 of the frame 1 with its opening facing downward, and a mounting area 20 for arranging a circumferential drive is formed between the bottom plate 11. The guide section 14 is vertically fixed on the top surface of the clearance section 15, and the guide section 14 passes through a guide slide hole 32 of the mounting plate 3. A lower push switch assembly 16 is also provided on the top surface of the yield section 15. The lower push switch assembly 16 is located directly below the mounting plate 3 and is used to send a signal to the processing end when the mounting plate 3 drops to the bottom; an upper push switch assembly 17 is provided on the bottom surface of the top plate 12 of the rack 1. The upper push switch assembly 17 is located directly above the mounting plate 3 and is used to send a signal to the processing end when the mounting plate 3 rises to the top; the guide section 14 includes an L-shaped main body 18 and a flip portion 19 hinged to one end of the L-shaped main body 18. The flip portion 19 is used to support upward in a vertical state and forms a drive disassembly and assembly port when it is opened outward.

[0051] Specifically, the clearance section 15 is U-shaped and opens downward, providing installation space for the circumferential drive, which is equivalent to the clearance section 15 spanning above the circumferential drive, so that the circumferential drive can be compactly installed on the frame 1. The guide section 14 is linear and vertically connected to the top of the clearance section 15, providing precise guidance for the lifting and lowering movement of the mounting plate 3, ensuring that the mounting plate 3 remains vertical and stable during the lifting process. The upper push switch assembly 17 and the lower push switch assembly 16 are respectively located at the upper and lower ends of the mounting plate 3, which is equivalent to being at the two ends of the moving path of the mounting plate 3. When the mounting plate 3 descends to the lowest position, it will touch the lower push switch assembly 16. When it rises to the highest position, it will touch the upper push switch assembly 17. The corresponding switch assembly will send a corresponding signal to the processing end, and the processing end will respond accordingly, effectively preventing the mounting plate 3 from damaging related components or causing other safety hazards due to excessive descent or rise, thereby ensuring the stable operation of the system. In addition, the guide section 14 is composed of an L-shaped main body 18 and a flip portion 19, which is equivalent to a U-shaped guide section 14 in which one side can be flipped outward. When the flip portion 19 is in a vertical state, it and the L-shaped main body 18 together constitute a complete guide section 14, ensuring a stable support effect. When the flip portion 19 is opened outward, a drive disassembly port is formed, providing an opening for the disassembly and assembly of the circumferential drive, thereby achieving flexible disassembly.

[0052] like Figure 1 、 3As shown, a gravity balancing mechanism 6 is provided between the mounting plate 3 and the frame 1. The gravity balancing mechanism 6 includes a rotating wheel 61 rotatably connected to the bottom surface of the top plate 12 of the frame 1. A connecting belt 62 is wound around the rotating wheel 61. One end of the connecting belt 62 is connected to the mounting plate 3, and the other end is connected to the counterweight 63. There are two sets of rotating wheels 61, one set located directly above the mounting plate 3 and the other located to the side of the mounting plate 3. Connecting rings 64 are fixed to each end of the connecting belt 62. The top surfaces of the mounting plate 3 and the counterweight 63 are both provided with docking hooks 65. The docking hooks 65 and the connecting rings 64 are detachably connected. The gravity balancing mechanism 6 is located on the side of the lifting drive mechanism 4 away from the drive screw 41.

[0053] Specifically, the gravity balancing mechanism 6 reduces the driving load of the lifting drive mechanism by balancing the gravity of the mounting plate 3 and the components thereon, wherein the rotating wheel 61 serves as a support and guide component for the connecting belt 62, and the connecting belt 62 is wound around the rotating wheel 61 to form a closed-loop system. The two ends of the connecting belt 62 are respectively connected to the mounting plate 3 and the counterweight block 63 to achieve gravity balance between the two. When the mounting plate 3 rises, the connecting belt 62 will drive the counterweight block 63 to descend, and vice versa, it will rise, ensuring that the balancing force is continuously applied, effectively reducing the driving load and saving energy consumption. Two sets of rotating wheels 61 are designed, located directly above and to the side. The upper rotating wheels 61 ensure that the pulling force on the mounting plate 3 is vertically upward, providing stable force. The side rotating wheels 61 position the lifting path of the counterweight 63 to the side of the mounting plate 3, avoiding interference between the lifting and lowering of the counterweight 63 and the mounting block. The ends of the connecting belt 62 are hooked and connected to the docking hooks 65 on the mounting plate 3 and the counterweight 63 via a connecting ring 64, providing flexible detachability and facilitating adjustment of the weight of the counterweight 63 according to actual needs. In addition, the gravity balancing mechanism 6 is located on the side of the lifting drive mechanism 4 away from the drive screw 41. This helps optimize the overall structure and mechanical performance of the system and reduces the deflection force between the mounting plate 3 and the vertical guide rod.

[0054] For illustration, the tooth structures of the driving wheel 43, the driven wheel 44, the locking gear 52 and the arc-shaped tooth surface 54 are not specifically shown in the figure. Figure 1 The side panels of the middle frame 1 are hidden and not shown.

[0055] Specific working principle: During use, when the height of the irradiation component 7 needs to be adjusted, the processing end sends a signal, the corresponding output end of the double-headed motor 47 drives the locking block 53 to retract, and the output end of the double-headed motor 47 controls the driving screw 41 to rotate, thereby realizing the height adjustment of the corresponding mounting plate 3 and the irradiation component 7 thereon. After adjustment, the output end of the double-headed motor 47 extends and resets, and the arc-shaped tooth surface 54 and the locking gear 52 engage and lock, thereby completing the stable locking of the irradiation component 7 at this height.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
