Abstract
Description
Technical Field
[0001] This invention belongs to the field of signal generators, and more specifically, relates to a radio frequency signal generator. Background Technology
[0002] Radio frequency (RF) signal generators are electronic devices widely used in communications, radar, electronic warfare, scientific research, and other fields. Their main function is to generate RF signals of specific frequencies, power, and modulation methods to meet various testing, measurement, and communication needs. However, existing RF signal generators suffer from numerous problems in practical use, which limit their performance and application scope.
[0003] Traditional RF signal generators typically use internal screw posts and screws for connection and fixation. However, in actual use, due to frequent movement, vibration, and long-term use, these connecting components are prone to loosening. Once loosening occurs, it not only affects the stability of the RF signal generator but may also lead to signal instability or even interruption, severely impacting the normal operation of the RF signal generator and the accuracy of test results. Furthermore, traditional fixing methods are cumbersome to disassemble and maintain, requiring significant time and effort, thus reducing the maintenance efficiency of the RF signal generator.
[0004] In some applications, the signal strength generated by an RF signal generator may be insufficient for long-distance transmission or use in complex environments. To improve signal transmission distance and quality, additional signal boosters are usually required; however, the storage of these boosters when not in use is a significant issue. Some existing RF signal generators have their boosters exposed outside the housing, making them susceptible to damage. Others require removal from the housing for storage when not in use, which is cumbersome and time-consuming.
[0005] Furthermore, RF signal generators generate a significant amount of heat during operation. If this heat cannot be dissipated in a timely manner, the internal temperature of the RF signal generator will rise, affecting its performance and lifespan. Existing RF signal generators typically employ natural cooling or simple fan cooling methods, which are ineffective. Under prolonged high-load operation, the internal temperature of the RF signal generator may continue to rise, leading to signal distortion, component damage, and other problems. Summary of the Invention
[0006] In view of the above-mentioned defects or improvement needs of the prior art, the present invention provides a radio frequency signal generator, which clamps the main body of the radio frequency signal generator by electric means, so as to stably and reliably fix the main body of the radio frequency signal generator.
[0007] To achieve the above objectives, according to one aspect of the present invention, a radio frequency signal generator is provided, comprising a protective housing, a fixing mechanism, and a radio frequency signal generator body, wherein:
[0008] The fixing mechanism includes a fixing frame, a first motor, a rotating shaft, and two sets of first clamping assemblies. The fixing frame is disposed inside the protective housing and has a guide groove. The first motor is fixedly mounted on the fixing frame.

[0015] The movable collar is fixedly installed on the transmission nut so that the reflector plate can be opened and closed by the adjusting rod when it moves with the transmission nut. When the transmission nut moves away from the second motor, the movable collar opens the reflector plate by the adjusting rod so that the reflector plate reflects the signal of the intensifier. When the transmission nut moves towards the second motor, the movable collar closes the reflector plate by the adjusting rod.
[0016] Preferably, the support base has a sleeve for accommodating the reinforcing device, the sleeve surrounds the transmission nut, the movable collar surrounds the sleeve, the movable collar is mounted on the transmission nut via a guide block, the sleeve is provided with a guide groove at a position corresponding to the guide block, and the guide block is slidably mounted in the guide groove.
[0017] Preferably, it further includes an installation mechanism, which includes an installation plate and two sets of second clamping assemblies;
[0018] Each set of the second clamping assembly includes a mounting frame, a pair of movable rods, a mounting clamp rod, a support slide rod, a sliding block, a compression spring, and a limiting slider.

The included angle between the two movable rods is greater than 0. Each end of the compression spring is fixedly connected to a sliding block.
[0019] The two mounting rods of the two sets of second clamping components cooperate to clamp the mounting plate, and the signal enhancement mechanism is fixedly mounted on the mounting plate.
[0020] Preferably, the mounting mechanism is located on top of the protective housing so as to secure the signal boosting mechanism to the top of the protective housing.
[0021] Preferably, the protective housing includes a housing, an observation window, and louvers. The housing has a first window and a second window respectively at positions corresponding to the observation window and the louvers. The observation window is hinged to the first window of the housing, and the louvers are fixedly installed at the second window of the housing. The housing also has an air inlet.
[0022] Preferably, the device further includes a heat dissipation mechanism, which includes a heat dissipation box, a filter screen, a perforated plate, a third motor, and heat dissipation fan blades.

[0023] Preferably, the heat dissipation mechanism further includes multiple sets of perforated plate connecting assemblies;
[0024] Each perforated plate connecting assembly includes a connecting block, a connecting base, a pin, and a fixing spring. The pin includes a pull rod and a fixing rod fixedly connected together.

The pin is inserted into the first and second pin holes to achieve a detachable connection between the perforated plate and the heat sink. The first pin hole is a stepped hole and includes interconnected components. The first hole segment and the second hole segment are provided, with the diameter of the first hole segment being larger than that of the second hole segment. The first hole segment is located between the second pin hole and the second hole segment. The fixing spring is mounted on the pull rod and is located within the first hole segment. The fixing insert is located within the second pin hole. The axial length of the first hole segment is not less than the axial length of the fixing insert along the second pin hole, so that the fixing insert can release the restriction on the connecting insert after entering the first hole segment, thereby facilitating the separation of the perforated plate from the heat sink. One end of the fixing spring applies a spring force to the fixing insert and the other end applies a spring force to the connecting base.
[0025] Preferably, the heat sink is mounted on the protective housing by fixing bolts.
[0026] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:
[0027] 1) In a radio frequency (RF) signal generator of the present invention, a first motor drives a rotating shaft of the fixing mechanism, which in turn drives a bevel gear mechanism and a transmission gear to rotate. This ultimately causes the moving frames of two sets of first clamping components to move horizontally along guide grooves, achieving clamping of the RF signal generator body by the fixing clamp. Compared with traditional screw posts and screw fixation, this mechanical clamping method provides a more stable and reliable fixing effect for the RF signal generator. During frequent movement, vibration, and long-term use of the RF signal generator, traditional screw fixing methods are prone to loosening. The clamping mechanism of the present invention effectively avoids such problems, ensuring that the RF signal generator body remains stable throughout its entire service life, preventing signal instability or even interruption due to loosening, thus guaranteeing the normal operation of the RF signal generator. Stable fixing effectively reduces vibration and displacement of the RF signal generator body during operation, thereby improving signal stability and accuracy.
[0028] 2) In the radio frequency signal generator of the present invention, since the movable frame of the first clamping component can move horizontally in the guide groove, and the clamping action of the two fixed clamping plates is realized by the meshing of the transmission gear and the rack, it can be adjusted according to the radio frequency signal generator body of different sizes, so that it can adapt to the radio frequency signal generator body of various specifications, thereby improving the versatility and flexibility of the radio frequency signal generator.
[0029] 3) In the radio frequency signal generator of the present invention, the first motor drive of the fixing mechanism realizes clamping and releasing. The main body of the radio frequency signal generator can be quickly disassembled and assembled by simply controlling the forward and reverse rotation of the first motor, which greatly saves time and effort and improves the maintenance efficiency of the radio frequency signal generator.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0043] Reference Figure 1 , Figures 6-8 A radio frequency signal generator includes a protective housing 1, a fixing mechanism 4, and a radio frequency signal generator body 5.
[0044] The fixing mechanism 4 includes a fixing frame 401, a first motor 402, a rotating shaft 403, and two sets of first clamping assemblies. The fixing frame 401 is disposed inside the protective housing 1. The fixing frame 401 is provided with a guide groove 412. The first motor 402 is fixedly installed on the fixing frame 401. The output shaft of the first motor 402 is horizontally arranged and coaxially connected to the rotating shaft 403. The main body 5 of the radio frequency signal generator is placed on the fixing frame 401.
[0045] Each of the first clamping assemblies includes a bevel gear mechanism 411, a transmission gear 406, a movable frame 410, and a fixed clamping plate 409. The bevel gear mechanism 411 includes a first bevel gear 404 and a second bevel gear 405 that mesh with each other. The first bevel gear 404 is fixedly mounted on the rotating shaft 403. The second bevel gear 405 is coaxially connected to the transmission gear 406 via a transmission shaft. The transmission shaft is rotatably mounted on the fixed frame 401. The movable frame 410 is slidably mounted in the guide groove 412 of the fixed frame 401 so as to move horizontally in a direction perpendicular to the output shaft of the first motor 402. The movable frame 410 has two racks 407, which are fixedly connected together by a connecting plate 408. The fixed clamping plate 409 is fixedly mounted on the movable frame 410.
[0046] The four racks 407 of the two sets of first clamping assemblies are parallel to each other, and the two second bevel gears 405 are located between the two first bevel gears 404 so that the rotation directions of the two second bevel gears 405 are opposite. The two first bevel gears 404 are mounted on the same rotating shaft 403 and the rotation directions of the two first bevel gears 404 are the same, but the teeth of the two first bevel gears 404 are arranged opposite to each other, so that when the two second bevel gears 405 are driven to rotate, the rotation directions of the second bevel gears 405 are opposite.
[0047] The two transmission gears 406 are the first transmission gear and the second transmission gear, respectively. One rack 407 of each movable frame 410 meshes with the first transmission gear, and the other rack 407 of each movable frame 410 meshes with the second transmission gear, so that the transmission gears 406 drive the two movable frames 410 to move closer and further apart, and when they move closer together, the radio frequency signal generator body 5 is clamped by two fixed clamps 409. See also Figure 7When the left transmission gear 406 rotates clockwise, the right transmission gear 406 rotates counterclockwise, so that the two moving frames 410 move away from each other, and vice versa.
[0048] During installation, the main body 5 of the radio frequency signal generator is placed between two fixed clamping plates 409. The first motor 402 is started, and the two first bevel gears 404 are rotated under the action of the rotating shaft 403. Under the meshing action of the first bevel gear 404 and the second bevel gear 405, the two transmission gears 406 are driven to rotate in opposite directions, causing the racks 407 on both sides of the transmission gears 406 to move towards each other. Under the action of the two connecting plates 408, the fixed clamping plates 409 on both sides are driven to move towards each other, thus completing the clamping and fixing of the main body 5 of the radio frequency signal generator.
[0049] Furthermore, refer to Figures 2-5 It also includes a signal enhancement mechanism 3, which includes a support base 301, a second motor 303, a lead screw mechanism, and an enhancer 305. The support base 301 is mounted on the protective housing 1, and the second motor 303 is mounted on the support base 301. The lead screw mechanism includes a lead screw 302 and a transmission nut 304 that passes through the lead screw 302. The lead screw 302 is mounted on the output shaft of the second motor 303, and the enhancer 305 is mounted on the transmission nut 304.
[0050] The second motor 303 drives the lead screw mechanism, enabling the amplifier 305 to move along the axial direction of the lead screw 302. This design allows for flexible adjustment of the position of the amplifier 305 according to actual needs, thereby achieving effective amplification of the radio frequency signal. In long-distance transmission or complex environments, the amplifier 305 can improve signal strength and stability, reduce signal attenuation and distortion during transmission, and ensure that the receiving end can receive a high-quality signal.
[0051] The signal enhancement mechanism 3 can be easily integrated with the control system of the RF signal generator, enabling real-time monitoring and automatic adjustment of the signal enhancement process. Based on the operating status of the RF signal generator and the signal transmission quality, the system can automatically adjust the position and operating state of the enhancer 305 to achieve optimal signal enhancement. By adjusting the position of the enhancer 305, the signal strength can be flexibly adjusted. In cases of weak signals, the enhancer 305 can be moved to a better position to enhance the signal; in cases of strong signals, the position of the enhancer 305 can be adjusted appropriately to avoid interference and distortion caused by excessive signal strength. This flexible adjustment method allows the RF signal generator to better adapt to different signal strength requirements, improving its performance in various application scenarios.
[0052] When the signal booster 305 is not in use, it can be retracted into the support base 301 via the second motor 303. This retraction method not only saves space and prevents the booster 305 from being affected or damaged by the external environment when idle, but also ensures that the retracted booster 305 does not interfere with other components of the RF signal generator, thus guaranteeing the normal operation of the RF signal generator.
[0053] Furthermore, the signal enhancement mechanism 3 also includes a movable collar 306 and a reflector assembly, wherein there are multiple reflector assemblies and they are circumferentially distributed along the center line of the lead screw 302.
[0054] Each reflector assembly includes a reflector 308, a guide slide 309, an adjusting rod 307, and a movable slider 3010. The guide slide 309 is mounted on the reflector 308, and the movable slider 3010 is slidably mounted on the guide slide 309. One end of the adjusting rod 307 is hinged to the movable collar 306 via hinge pin A, and the other end is hinged to the movable slider 3010 via hinge pin B. The reflector 308 is hinged to the support base 301 via hinge pin C. The hinge pins A, B, and C are triangularly distributed and their axes are parallel.
[0055] The movable collar 306 is fixedly mounted on the transmission nut 304 so that when it moves with the transmission nut 304, it can open and close the reflector 308 via the adjusting rod 307. When the transmission nut 304 moves away from the second motor 303, the movable collar 306 opens the reflector 308 via the adjusting rod 307 so that the reflector 308 can reflect the signal of the reflector intensifier 305. When the transmission nut 304 moves towards the second motor 303, the movable collar 306 closes the reflector 308 via the adjusting rod 307.
[0056] The second motor 303 starts, driving the lead screw 302 to rotate. Under the action of the thread of the lead screw 302, the transmission nut 304 and the reinforcing device 305 move upward. Since the transmission nut 304 is externally fixedly connected to the movable collar 306, the movable collar 306 moves upward accordingly. Since the adjusting rod 307 is movably hinged to the movable collar 306 and the movable slider 3010 respectively, and the support base 301 is movably hinged to the reflector 308, the circumferential reflector 308 is opened, and the reinforcing device 305 is pushed out to start working. When not in use, the reinforcing device 305 is stored inside the support base 301, and the reflector 308 is also retracted, surrounding the reinforcing device 305.
[0057] The opening and closing of the reflector 308 is controlled by the movable collar 306, which is achieved through the movement of the transmission nut 304. This adjustable design not only enhances the signal but also allows for adjustment of the signal enhancement range according to actual needs. When concentrated signal transmission is required, the reflector 308 can be opened to a larger angle for long-distance transmission; when close-range coverage is required, the reflector 308 can be appropriately closed to reduce signal diffusion and improve signal concentration.
[0058] When the amplifier 305 moves and the reflector 308 is extended, a better reflection angle is formed, reflecting and focusing the signal emitted by the amplifier 305, thereby further enhancing the signal strength and directionality. This dynamic reflection mechanism ensures that the signal energy is increased during transmission, thereby improving the signal transmission efficiency and quality, especially in long-distance transmission and complex environments, significantly improving signal stability and reliability.
[0059] The reflector assembly is circumferentially distributed along the centerline of the lead screw 302, forming multiple reflective surfaces. This multi-angle reflection design enables omnidirectional signal enhancement and coverage. In practical applications, regardless of the direction of signal reception, the reflector 308 can effectively reflect the signal to the target area, reducing signal blind spots and improving signal coverage and uniformity.
[0060] Furthermore, the support base 301 has a sleeve 3011 for accommodating the amplifier 305. The sleeve 3011 surrounds the transmission nut 304, and the movable collar 306 surrounds the sleeve 3011. The movable collar 306 is mounted on the transmission nut 304 via a guide block 3013. The sleeve 3011 has a guide groove 3012 at a position corresponding to the guide block 3013, and the guide block 3013 is slidably mounted in the guide groove 3012. The cooperation between the guide block 3013 and the guide groove 3012 can effectively restrict the movement direction of the movable collar 306, preventing it from shifting or jamming during movement, thereby ensuring the normal operation of the signal enhancement mechanism 3. When not in use, the amplifier 305 can be retracted into the sleeve 3011 under the drive of the transmission nut 304.
[0061] Furthermore, refer to Figure 2 It also includes an installation mechanism 2, which includes an installation plate 209 and two sets of second clamping components.
[0062] Each set of the second clamping assembly includes a mounting bracket 201, a pair of movable rods 202, a mounting clamping rod 203, a support slide rod 204, a sliding block 205, a compression spring 206, and a limiting slider 208. The mounting bracket 201 is fixed to the protective housing 1, preferably mounted on the top plate of the protective housing 1, and the mounting bracket 201 is a U-shaped bracket. The mounting bracket 201 includes two parallel side rods and a middle rod connecting the two side rods. Limiting grooves 207 are respectively provided on the opposite sides of the two side rods. Each end of the mounting clamping rod 203 slides through a limiting slider 208. The movable rod 202 is movably installed in a limiting slide groove 207. The supporting slide rod 204 is fixedly installed on the mounting clamp rod 203 and is parallel to the mounting clamp rod 203. The two sliding blocks 205 are slidably installed on the supporting slide rod 204. One end of each movable rod 202 is hinged to the intermediate rod through a hinge pin D, and the other end of each movable rod 202 is hinged to a sliding block 205 through a hinge pin E. The included angle between the two movable rods 202 is greater than 0. Each end of the compression spring 206 is fixedly connected to a sliding block 205.
[0063] The two mounting rods 203 of the two sets of second clamping components cooperate to clamp the mounting plate 209, and the signal enhancement mechanism 3 is fixedly installed on the mounting plate 209.
[0064] During operation, the two mounting clamp rods 203 are pushed in opposite directions, causing the two sliding blocks 205 to move towards each other along the support slide rod 204, compressing the compression spring 206. Then, the mounting plate 209 is inserted between the two mounting clamp rods 203. Since the two sliding blocks 205 are elastically connected by the compression spring 206, under the elastic force of the compression spring 206, the sliding blocks 205 on both sides are pushed to move in opposite directions, thereby pushing the two mounting clamp rods 203 to move towards each other, installing and fixing the mounting plate 209, and completing the fixed installation of the signal enhancement mechanism 3.
[0065] In actual RF signal generator maintenance and repair, the signal enhancement mechanism 3 is frequently installed and removed. This mounting mechanism 2 takes this into full consideration; the ingenious structure of its second clamping component makes the installation and removal process extremely simple and quick. By pushing the mounting clamps 203 on both sides in opposite directions, the mounting plate 209 can be easily inserted or removed without the need for additional tools, greatly saving installation and removal time. Traditional installation methods may rely solely on simple screws or clips for fixation, which are easily loosened by vibration, movement, or long-term use of the RF signal generator, thus affecting the normal operation of the signal enhancement mechanism 3.
[0066] The compression spring 206 in the second clamping assembly has a certain buffering effect. When the RF signal generator is subjected to external vibration or impact, it can effectively absorb and buffer these forces, reducing the direct impact on the signal enhancement mechanism 3. This buffering effect helps protect the precision components inside the signal enhancement mechanism 3, reduces the risk of component damage caused by external vibration or impact, thereby further improving the stability and reliability of the RF signal generator and extending its service life.
[0067] Furthermore, the mounting mechanism 2 is located on the top of the protective housing 1 so as to fix the signal enhancement mechanism 3 on the top of the protective housing 1. The installation position at the top facilitates the diffusion of the signal in all directions, improves the coverage and uniformity of the signal, and further enhances the performance and efficiency of the radio frequency signal generator.
[0068] Furthermore, the protective housing 1 includes a housing 101, an observation window 102, and a louver 103. The housing 101 is provided with a first window and a second window at positions corresponding to the observation window 102 and the louver 103, respectively. The observation window 102 is hinged to the first window of the housing 101, and the louver 103 is fixedly installed at the second window of the housing 101. The housing 101 is also provided with an air inlet 104.
[0069] The observation window 102 allows operators to directly observe the operating status of the radio frequency signal generator inside the protective housing 1. Hinged at the first window of the housing 101, the observation window 102 not only provides excellent visibility but also allows for easy opening and closing, facilitating inspection and maintenance of the internal radio frequency signal generator body 5. Through the observation window 102, operators can monitor the operation of the radio frequency signal generator body 5 in real time, promptly identify potential problems, and ensure the normal operation of the radio frequency signal generator body 5.
[0070] The louver 103 provides excellent ventilation and heat dissipation for the radio frequency signal generator. The louver 103 is fixedly installed at the second window of the housing 101. This design effectively guides airflow, promptly dissipating the heat generated inside the radio frequency signal generator. By adjusting the louver 103, the ventilation volume can be flexibly adjusted according to the operating status of the radio frequency signal generator and the ambient temperature, ensuring that the radio frequency signal generator maintains good heat dissipation under different operating conditions.
[0071] The air inlet 104 on the housing 101 works in conjunction with the louvers 103 to create good air convection. The design of the air inlet 104 ensures that sufficient fresh air enters the RF signal generator, forming convection with the hot air exhausted from the louvers 103, further improving heat dissipation efficiency. This reasonable ventilation design not only reduces the internal temperature of the RF signal generator but also reduces RF signal generator malfunctions and signal distortion caused by high temperatures, improving the reliability and stability of the RF signal generator.
[0072] Furthermore, refer to Figure 9 It also includes a heat dissipation mechanism 6, which includes a heat dissipation box 601, a filter screen 603, a perforated plate 604, a third motor 606, and heat dissipation fan blades 605. The heat dissipation box 601 is disposed inside the protective shell 1. A first opening is provided on one side of the heat dissipation box 601 and the filter screen 603 is fixed at the first opening. A second opening is provided on the side of the heat dissipation box 601 opposite to the filter screen 603 and the perforated plate 604 is fixed at the second opening. The third motor 606 is mounted on the perforated plate 604. The motor housing of the third motor 606 is located outside the heat dissipation box 601. Several heat dissipation fan blades 605 are located inside the heat dissipation box 601. The output end of the third motor 606 passes through the perforated plate 604 and is fixedly connected to each heat dissipation fan blade 605.
[0073] As the core component of the heat dissipation mechanism 6, the heat sink 601 provides a stable environment for the heat dissipation process. The filter 603 effectively filters the air entering the heat sink 601, preventing dust and other impurities from entering the RF signal generator, thereby improving heat dissipation efficiency and reducing RF signal generator failures. The perforated plate 604 facilitates air circulation, allowing the cooling fan blades 605 to more effectively expel heat from the RF signal generator.
[0074] The heat dissipation mechanism 6 adopts an active cooling method, using a third motor 606 to drive the cooling fan blades 605 to rotate, accelerating airflow and rapidly dissipating the heat generated inside the RF signal generator. Compared with traditional natural cooling or simple fan cooling, this active cooling mechanism can more effectively reduce the internal temperature of the RF signal generator. Especially during long-term high-load operation, it can significantly reduce signal distortion and component damage caused by high temperatures, thereby improving the reliability and lifespan of the RF signal generator.
[0075] Furthermore, the heat sink 601 is mounted on the protective housing 1 by fixing bolts 602. This fixing method not only ensures the stability of the heat dissipation mechanism 6, but also facilitates installation and disassembly. A stable heat dissipation system can ensure that the RF signal generator maintains good heat dissipation under various operating conditions, reducing overheating and malfunctions of the RF signal generator caused by poor heat dissipation, thereby improving the stability and reliability of the RF signal generator.
[0076] Furthermore, refer to Figure 10 The heat dissipation mechanism 6 also includes multiple sets of perforated plate connecting assemblies 6014 to achieve a detachable connection between the perforated plate 604 and the heat dissipation box 601.
[0077] Each perforated plate connecting assembly 6014 includes a connecting block 607, a connecting base 608, a pin, and a fixing spring 6011. The pin includes a pull rod 609 and a fixing rod 6010 fixedly connected together. The connecting base 608 is fixed to the heat sink 601, and the connecting block 607 is fixed to the perforated plate 604. The connecting base 608 has a socket, and the connecting block 607 is inserted into the socket. The connecting base 608 has a first pin hole 6012, and the connecting block 607 has a second pin hole 6013. The pin is inserted into the first pin hole 6012 and the second pin hole 6013 to achieve a detachable connection between the perforated plate 604 and the heat sink 601. The first pin hole 6012 is a stepped hole, and the first pin hole 601... 2 includes a first hole segment and a second hole segment that are interconnected, with the diameter of the first hole segment being larger than that of the second hole segment. The first hole segment is located between the second pin hole 6013 and the second hole segment. The fixing spring 6011 is mounted on the pull rod 609 and is located within the first hole segment. The fixing insert 6010 is located within the second pin hole 6013. The axial length of the first hole segment is not less than the axial length of the fixing insert 6010 along the second pin hole 6013, so that after the fixing insert 6010 exits the second pin hole 6013 and enters the first hole segment, the restriction on the connecting insert 607 is released, thereby facilitating the separation of the perforated plate 604 from the heat sink 601. One end of the fixing spring 6011 applies a spring force to the fixing insert 6010, and the other end applies a spring force to the connecting base 608. The connecting base 608 can be installed in two halves so that the fixing insert 6010 can be inserted into the second pin hole 6013.
[0078] When the perforated plate 604 is installed onto the heat sink 601, pulling the lever 609 moves the fixing rod 6010 away from the connecting base 608, causing the connecting block 607 to insert into the connecting base 608. Then, the lever 609 is released. Since the fixing rod 6010 is elastically connected to the connecting base 608 through the fixing spring 6011, under the elastic force of the fixing spring 6011, the fixing rod 6010 is pushed into the second pin hole 6013, thus fixing the connecting block 607 and completing the installation and fixing of the heat sink 601 and the perforated plate 604. Then, the third motor 606 starts and drives several cooling fan blades 605 to rotate, causing external air to flow from the perforated plate 604 into the housing 101, blowing out the internal heat through the louvers 103.
[0079] The retaining spring 6011 provides stable elasticity, ensuring that the retaining rod 6010 is securely inserted into the second pin hole 6013, thereby guaranteeing a tight connection between the perforated plate 604 and the heat sink 601. This tight connection is crucial for the normal operation of the heat dissipation mechanism 6, as the cooling fan generates vibrations during operation. If the connection is not secure, the perforated plate 604 may loosen, affecting the heat dissipation effect. This design effectively prevents components from loosening due to vibration, improving the reliability of the heat dissipation mechanism 6 during long-term operation.
[0080] The design of the perforated plate connecting assembly 6014 allows for a detachable connection between the perforated plate 604 and the heat sink 601. This design significantly improves the ease of maintenance of the heat dissipation mechanism 6. In practical use, if the heat dissipation mechanism 6 requires maintenance, such as damage to the perforated plate 604 or cleaning of dust inside the heat sink 601, operators can easily separate the perforated plate 604 from the heat sink 601 by pulling the lever 609, causing the fixing rod 6010 to disengage from the second pin hole 6013. This quick disassembly method saves maintenance time and improves the maintainability of the RF signal generator. Moreover, this detachable structure also makes the replacement process more convenient when components of the heat dissipation mechanism 6 need to be replaced.
[0081] The working process of this invention is as follows:
[0082] In actual use, firstly, by pushing the mounting clamps 203 on both sides in opposite directions, the two sliding blocks 205 move towards each other along the support slide rod 204, inserting the mounting plate 209 into the top of the housing 101. Then, by using the compression spring 206 to push the sliding blocks 205 on both sides to move in opposite directions, the mounting clamps 203 on both sides move towards each other. The two mounting clamps 203 clamp the mounting plate 209, completing the fixed installation of the reinforcing device 305 on the mounting plate 209.
[0083] Next, the main body 5 of the radio frequency signal generator is placed between two fixed clamping plates 409. The first motor 402 causes the two first bevel gears 404 to rotate, which drives the transmission gear 406 to rotate and pushes the racks 407 on both sides to move towards each other. Under the action of the connecting plate 408, the fixed clamping plates 409 on both sides move towards each other, thus completing the clamping and fixing of the main body 5 of the radio frequency signal generator.
[0084] Next, the second motor 303 drives the lead screw 302 to rotate, causing the transmission nut 304 to push the enhancer 305 upward. The movable collar 306 opens the reflectors 308 on all four sides, pushing the enhancer 305 out to start working. When not in use, the enhancer 305 can be stored inside the support base 301, and the reflectors 308 will also retract.
[0085] Finally, the perforated plate 604 is connected to the heat sink 601. By pulling the upper and lower levers 609, the upper and lower fixing rods 6010 are moved in opposite directions, so that the two connecting blocks 607 are inserted into the corresponding connecting bases 608 respectively. The fixing spring 6011 pushes the fixing rod 6010 into the second pin hole 6013 to fix the connecting block 607, thus completing the installation and fixing of the heat sink 601 and the perforated plate 604. The third motor 606 drives several cooling fan blades 605 to rotate, so that the outside air flows into the housing 101 from the perforated plate 604, and blows the heat in the housing 101 out through the louvers 103.
[0086] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
