Description

Technical Field

[0001] The present application relates to the technical field of magnetic levitation rotor technology, and in particular to a performance test platform and system for a magnetic levitation rotor power system. Background Art

[0002] Currently, the application of magnetic levitation technology is booming both domestically and internationally, with the most mature applications primarily focused on maglev trains. In recent years, the continuous development of magnetic levitation technology has led to the application of magnetic levitation technology to rotorcraft, which has become a new design concept for rotorcraft. This has led to the development of magnetic levitation rotor propulsion systems.

[0003] At the same time, the testing technology for the performance of magnetic levitation rotor power systems is still immature. For example, Comparative Document 1 (Announcement No. CN215641703U, patentee Zero Gravity Nanjing Aircraft Industry Co., Ltd.) discloses a multi-rotor UAV power system measurement test bench, including a lever mechanism, an adjustment unit, a frame unit, a power unit, a pressure test unit and a test unit. The frame unit includes a test bench and a support seat. The middle part of the lever mechanism is arranged on the support seat, the front end of the lever mechanism is provided with a test unit, and the rear end is provided with an adjustment unit and a counterweight. The adjustment unit includes a slide rail, a flange and a push rod arranged in sequence from top to bottom. The test unit includes several motor test pieces and blade test pieces installed at the front end of a lever mechanism. In Comparative Document 1, the blade test piece is installed on the lever mechanism, and the lever mechanism is movably connected to the test bench. When the test is carried out, the lift generated by the rotation of the blade test piece drives the blade test piece to move. Since the blade test piece is installed on the lever mechanism, and the lever mechanism is movably connected to the test bench, the motion trajectory of the blade test piece is a circular motion with the connection point between the lever mechanism and the test bench as the center. Since the performance test of the magnetic levitation rotor power system requires that the magnetic levitation rotor power system meet the operating requirements of being loaded on the rotorcraft (that is, the magnetic levitation rotor power system can only move linearly along the axial direction of the magnetic levitation power suspension system, and cannot rotate in the horizontal circumferential direction of the magnetic levitation rotor power system or displace in the horizontal direction), the measurement test bench provided in the prior art cannot ensure that the actual operating state of the magnetic levitation rotor power system in the performance test meets the operating requirements of being loaded on the rotorcraft. Summary of the Invention

[0010] In one embodiment, the adjustment dial further includes: an adjustment lever, which is mounted on the adjustment dial; an adjustment positioner, which is mounted on the mounting portion; and a first positioning hole, which is mounted on the adjustment positioner and cooperates with the adjustment lever.

[0016] In one embodiment, the constraint portion includes: a constraint fixing ring, which is installed above the support portion; and a third connecting rod, one end of which is detachably connected to the constraint fixing ring and the other end is rotatably connected to the support portion.

[0019] The test bench unit provided in the present application includes a mounting portion, on which are provided three supporting portions, and the supporting portions and the mounting portions are perpendicular to each other, and a clamping portion is slidably connected to the supporting portion. Firstly, since the three supporting portions are slidably connected to the clamping portions, the positions of the clamping portions on the supporting portions can be adjusted respectively by sliding the clamping portions so that each clamping portion is located in the same horizontal plane. Therefore, when the magnetic levitation rotor power system is installed on the test bench unit, the three clamping portions can be used to perform three-point planar support on the magnetic levitation rotor power system, that is, the magnetic levitation rotor power system is kept in a horizontal plane, thereby achieving stable clamping support for the magnetic levitation rotor power system and limiting the position of the magnetic levitation rotor power system to be parallel to the horizontal plane. The clamping and fixing of the levitation rotor power system can constrain the rotation of the magnetic levitation rotor power system in the horizontal axis and constrain its displacement in the horizontal direction when the magnetic levitation rotor power system is working. At the same time, through the sliding cooperation between the clamping part and the support part, and the position limitation between the support part and the mounting part, the magnetic levitation rotor power system can be limited to linear motion along its axial direction when it is working. Therefore, the test bench unit can constrain the rotation of the magnetic levitation rotor power system in the horizontal circumferential direction, constrain its displacement in the horizontal direction and limit the magnetic levitation rotor power system to linear motion along its axial direction, so that during the performance test of the magnetic levitation rotor power system, the actual operating state of the magnetic levitation rotor power system meets the operating requirements of the aircraft.

[0021] A performance test system for a magnetic levitation rotor power system provided in the present application includes a performance test platform for the magnetic levitation rotor power system. Since the performance test platform for the magnetic levitation rotor power system can constrain the horizontal circumferential rotation of the magnetic levitation rotor power system, constrain its horizontal displacement and limit the magnetic levitation rotor power system to only linear motion along its axial direction, the actual operating state of the magnetic levitation rotor power system meets the operating requirements of being loaded on an aircraft during the performance test of the magnetic levitation rotor power system.

[0048] like Figure 1 、 Figure 2 and Figure 5 、 Figure 6 As shown, the X-axis direction is the radial direction of the magnetic levitation rotor power system 1; the Y-axis direction is the axial direction of the magnetic levitation rotor power system 1, wherein the X-axis direction is perpendicular to the Y-axis direction.

[0049] Example 1

[0050] like Figure 1-11 A performance test platform for a magnetically levitated rotor power system is shown, and the test platform includes:

[0051] The mounting portion 23, specifically, is preferably a mounting disc 231 in order to facilitate the reasonable arrangement of various loads on the mounting portion; at the same time, in order to facilitate the measurement of the rotational speed and tilt angle data during the test of the magnetic levitation rotor power system 1, and to further simplify the structure of the test platform, preferably, a rotational speed sensor 53 is fixedly installed at the center of the mounting disc 231 through a connecting piece, and a single-axis tilt sensor 51 is fixedly installed at the edge of the mounting disc 231, and the corresponding data are collected by setting the rotational speed sensor 53 and the single-axis tilt sensor 51.

[0052] In order to reduce the manufacturing cost of the weight of the mounting disc 231 and avoid the airflow generated by the magnetic levitation rotor power system during the test from affecting the test process, specifically, the edge of the mounting disc 231 is respectively provided with a first hollow portion 2311, a second hollow portion 2312, and a third hollow portion 2313, and the first hollow portion 2311, the second hollow portion 2312, and the third hollow portion 2313 are respectively evenly arranged along the circumference of the mounting disc 231, and at least one fourth hollow portion 2314 is further provided at the center of the mounting disc 231; in this embodiment, firstly, by providing a first hollow portion 2311 on the mounting disc 231, The first hollow portion 2311, the second hollow portion 2312, the third hollow portion 2313 and the fourth hollow portion 2314 are arranged so as to effectively reduce the weight and production cost of the mounting disc 231 compared to a solid disc. At the same time, the airflow generated by the magnetic levitation rotor power system can be guided away from the mounting disc 231 by the first hollow portion 2311, the second hollow portion 2312, the third hollow portion 2313 and the fourth hollow portion 2314, thereby effectively preventing the solid disc from rebounding the airflow to the magnetic levitation rotor power system after contacting the airflow, thereby affecting the testing process of the magnetic levitation rotor power system.

[0053] The support portion 21 includes a clamping portion 22, which is slidably mounted on the support portion 21. There are at least three support portions 21, and at least three of the support portions 21 are respectively vertically mounted on the mounting portion 23. Specifically, in order to achieve stable support for the magnetic levitation rotor power system 1, the preferred number of support portions 21 is three, and the three support portions 21 are respectively vertically mounted on the mounting portion 23, that is, the angle between the three support portions 21 and the mounting portion 23 is 90°.

[0054] The test bench unit 2 provided in this embodiment includes a mounting disc 231, on which three supporting parts 21 are provided, and the supporting parts 21 and the mounting disc 231 are perpendicular to each other, and the supporting parts 21 are slidably connected with the clamping parts 22. First, since the three supporting parts 21 are all slidably connected with the clamping parts 22, the positions of the clamping parts 22 can be adjusted respectively by sliding the clamping parts 22 so that each clamping part 22 is located in the same horizontal plane, so that the three clamping parts 22 can be used to perform three-point planar support on the magnetic levitation rotor power system 1, thereby achieving stable clamping support for the magnetic levitation rotor power system 1 and limiting the position of the magnetic levitation rotor power system 1 to be parallel to the horizontal plane. At the same time, the clamping and fixing of the magnetic levitation rotor power system 1 by the clamping parts 22 can constrain its rotation in the horizontal axis and its displacement in the horizontal direction when the magnetic levitation rotor power system 1 is working, and at the same time, the sliding cooperation between the clamping parts 22 and the supporting parts 21 is achieved. , and the position limitation between the support part 21 and the mounting disc 231, the magnetic levitation rotor power system 1 can be limited to perform linear motion along its axial direction when working (that is, the motion trajectory of the magnetic levitation rotor power system 1 can only be along the axial (Y-axis) direction of the magnetic levitation rotor power system 1, and perform linear motion relative to the support part 21), so the test bench unit 2 can constrain the horizontal circumferential rotation of the magnetic levitation rotor power system 1, constrain its displacement in the horizontal direction and limit the magnetic levitation rotor power system 1 to perform linear motion along its axial direction, so that during the performance test of the magnetic levitation rotor power system 1, the actual operating state of the magnetic levitation rotor power system 1 meets the operating requirements loaded on the aircraft (that is, the magnetic levitation rotor power system 1 can only perform linear motion along the axial direction of the magnetic levitation power suspension system 1, and will not rotate horizontally circumferentially or displace in the horizontal direction of the magnetic levitation rotor power system 1).

[0055] In order to make the test bench unit adapt to the installation of magnetic levitation rotor power systems of different sizes and models, this embodiment further includes: a driving part 24, the driving part 24 is installed on the mounting part 23, and the driving part 24 is connected to the support part 21; wherein the driving part 24 drives the support part 21 to move to adjust the distance between the support parts 21.

[0056] The test bench unit provided in this embodiment also includes a driving part 24, which is driven and connected to the support part 21. Since the driving part 24 is driven and connected to the support part 21, the driving part 24 can drive the three support parts 21 to move respectively relative to the mounting part 23 and toward or away from the center point of the mounting part 23, so that the distance between the three support parts 21 can be adjusted according to the size of the magnetic levitation rotor power system 1 (for example, when the shape of the magnetic levitation rotor power system 1 is circular, the size of the magnetic levitation rotor power system 1 is the radius of the magnetic levitation rotor power system 1) by moving the support part 21, so that the distance between the three support parts 21 meets the size of the magnetic levitation rotor power system 1, thereby facilitating the installation of magnetic levitation rotor power systems 1 of different sizes on the test bench unit.

[0057] In order to achieve the clamping of magnetic levitation rotor power systems of different sizes and models, in this embodiment, preferably, the clamping part 22 includes: a clamping jaw 221, the clamping jaw 221 includes an upper clamping jaw 222 and a lower clamping jaw 223, and the upper clamping jaw 222 and the lower clamping jaw 223 are respectively slidably installed on the support part 21. Specifically, in order to facilitate the adjustment of the distance between the upper clamping jaw 222 and the lower clamping jaw 223, preferably, the sliding cooperation between the upper clamping jaw 222 and the lower clamping jaw 223 and the support part 21 can adopt a sliding cooperation structure such as a slide rail and a slide groove, a ball and a slide groove.

[0058] The clamping portion 22 provided in this example includes a clamping jaw 221 consisting of an upper clamping jaw 222 and a lower clamping jaw 223, and the upper clamping jaw 222 and the lower clamping jaw 223 are respectively slidably installed on the support portion 21. Since the upper clamping jaw 222 and the lower clamping jaw 223 slide on the support portion 21 respectively, the distance between the upper clamping jaw 222 and the lower clamping jaw 223 can be adjusted by sliding. By adjusting the distance, the clamping portion 22 can clamp magnetic levitation rotor power systems 1 of different sizes and models (for example, the width of the magnetic levitation rotor power system 1 along its axial direction).

[0059] In order to make the clamping and fixing of the clamping part 22 more stable, preferably, the upper clamping jaw 222 and the lower clamping jaw 223 are respectively fixedly connected with rubber pads that match the outer shape of the magnetic levitation rotor power system 1. By providing rubber pads that match the outer shape of the magnetic levitation rotor power system 1, the friction between the upper clamping jaw 222 and the lower clamping jaw 223 and the magnetic levitation rotor power system 1 is increased, thereby making the clamping and fixing of the clamping part 22 more stable.

[0060] This embodiment goes a step further, in order to facilitate the coordinated measurement with the force sensor, the clamping portion 22 also includes a clamping jaw top plate 224, which can be fixedly connected to the upper clamping jaw 222 by welding or integral molding. The force sensor 52 is fixedly installed on the upper end of the support portion 21 through the force sensor mounting plate. By cooperating with the clamping jaw top plate 224 and the mechanical sensor 52 installed on the upper end of the support portion 21, the lift data of the magnetic levitation rotor power system 1 during the test can be collected. Specifically, when the magnetic levitation rotor power system 1 is running, it can move up and down along the support portion 21. When the magnetic levitation rotor power system 1 is running and rising, the contact between the clamping jaw top plate 224 on the clamping portion 22 and the force sensor 52 can measure the lift data of the magnetic levitation rotor power system 1 during the test.

[0061] In order to constrain the movement of the upper portion of the support portion, the present embodiment further includes a constraint portion 25 , which is installed on the upper portion of the support portion 21 and constrains the movement of the support portion 21 .

[0062] The constraint portion 25 provided in this embodiment is set to be relatively long because the length of the support portion 21 is set to meet the requirements of the performance test of the magnetic levitation rotor power system 1. If only one end of the support portion 21 is connected to the mounting portion 23, the other end (upper portion) of the support portion 21 will swing under the action of external force. In order to avoid the above-mentioned swinging, the constraint portion 25 is provided on the upper portion of the support portion 21 to constrain the upper portion of the support portion 21, thereby realizing the constraint on the movement (swing) of the upper portion of the support portion 21.

[0063] In order to adjust the inclination angle of the mounting portion, the present embodiment further includes: an angle tilting assembly 31, the mounting portion 23 is rotatably mounted on the angle tilting assembly 31, and in order to achieve rotation between the mounting portion 23 and the angle tilting assembly 31, preferably, the second mounting seat 316 of the angle tilting assembly 31 is fixedly mounted with an upper connecting plate at one end where it is connected to the mounting portion 23, and the mounting portion 23 is fixedly mounted with a lower connecting plate at one end where it is connected to the second mounting seat 316, and the upper connecting plate and the lower connecting plate can be rotatably connected by the cooperation of the pin shaft and the pin hole;

[0064] The angle tilting assembly 31 includes: a driving motor 311; a second lead screw 312, the second lead screw 312 is rotatably mounted on the driving motor 311; a second lead screw slider 313, the second lead screw slider 313 is slidably mounted on the second lead screw 312; a fourth connecting rod 314, one end of the fourth connecting rod 314 is rotatably mounted on the second lead screw slider 313, specifically, the rotational connection between the fourth connecting rod 314 and the second lead screw slider 313 can be achieved by cooperating with the pin shaft and the pin hole, and the other end can be rotatably mounted on the mounting portion 23, specifically, the rotational connection between the fourth connecting rod 314 and the mounting portion 23 can be achieved by cooperating with the pin shaft and the pin hole. In order to better support the mounting portion 23, preferably, the shape of the fourth connecting rod 314 is "Y"-shaped, that is, the fourth connecting rod 314 is limited by the above shape, so that the end connected to the mounting portion of the fourth connecting rod forms a support for two points of the mounting portion 23, thereby achieving better support for the mounting portion 23.

[0065] The angle tilting assembly provided in this embodiment includes a driving motor 311, a second lead screw 312, a second lead screw slider 313 and a fourth connecting rod 314. The driving motor 311 rotates in coordination with the second lead screw 312, the second lead screw slider 313 slides in coordination with the second lead screw 312, and the two ends of the fourth connecting rod 314 rotate in coordination with the second lead screw slider 313 and the mounting portion 23, and the angle tilting assembly 31 rotates in coordination with the mounting portion 23. First, the second lead screw 312 is driven to rotate by the driving motor 311, and the rotation of the second lead screw 312 drives the second lead screw slider 313 to move relative to the second lead screw 312. Since the two ends of the fourth connecting rod 314 rotate in coordination with the second lead screw slider 313 and the mounting portion 23, respectively, the movement of the second lead screw slider 313 can drive the mounting portion 23 to rotate through the fourth connecting rod 314, thereby realizing the adjustment of the tilting angle of the mounting portion.

[0066] In order to prevent the second lead screw from bending under pressure, in this embodiment, preferably, the angle tilting assembly 31 also includes: a second mounting seat 316; a first mounting seat 315, the first mounting seat 315 is installed on the second mounting seat 316, and the two ends of the second lead screw 312 are respectively connected to the first mounting seat 315. In order to facilitate the rotation of the second lead screw 312, preferably, the two ends of the second lead screw 312 are respectively connected to the first mounting seat 315 through bearings; a first support slider 320, the first support slider 320 is installed on the second lead screw slider 313; a first support rail 321, the first support rail 321 is installed on the second mounting seat 316, and the first support rail 321 and the first support slider 320 are slidably matched.

[0067] The angle tilting assembly 31 provided in this embodiment also includes a second mounting seat 316, a first mounting seat 315, a first support slider 320 and a first support rail 321. The first mounting seat 315 is installed on the second mounting seat 316, and the two ends of the second lead screw 312 are respectively connected to the first mounting seat 315. The first support slider 320 is installed on the second lead screw slider 313, and the first support rail 321 is installed on the second mounting seat 316 and slides with the first support slider 320. First, because both ends of the second lead screw 312 are connected to the first mounting seat 315, the first mounting seat 315 can provide support for both ends of the second lead screw 312, thereby dispersing the pressure acting on the second lead screw 312. Second, because the first support slider 320 and the first support rail 321 are provided between the second mounting seat 316 and the second lead screw slider 313, and because the first support rail 321 has a strong load-bearing capacity, the pressure acting on the second lead screw 312 can be dispersed in the direction of force transmission through the second lead screw slider 313, the first support slider 320, the first support rail 321, and the second mounting seat 316. Therefore, the cooperation between the first mounting seat 315, the first support slider 320, and the first support rail 321 can effectively disperse the pressure on the second lead screw 312, preventing the pressure generated by the load on the mounting portion 23 from being concentrated on the second lead screw 312, causing the second lead screw 312 to be compressed and bent.

[0068] At the same time, in order to make the output of the driving motor more stable, preferably, a coupling 318 is also installed at the connection between the driving motor 311 and the second lead screw 312.

[0069] In order to make the working state of the driving motor more stable, preferably, the driving motor 311 can be fixedly mounted on the second mounting base 316 through the driving motor mounting base 317 .

[0070] In order to prevent the mounting portion from impacting the load thereunder during rotation, preferably, the first mounting seat 315 is fixedly mounted with a limit stopper 319 above one end of the first driving motor 311 .

[0071] Example 2

[0072] The same parts of this embodiment as those of embodiment 1 are not described here in detail. The difference between this embodiment and embodiment 1 is that Figure 2-4As shown, the driving part 24 includes: a column support 241, which is mounted on the support part 21; a first linear module, which is mounted on the mounting part 23, and the output end of the first linear module is connected to the column support 241. Specifically, in order to realize the driving of the three supporting parts 21 to move respectively, there are three column supports 241, three column supports 241, and the three supporting parts 21 are fixedly connected to the three column supports 241 respectively. Preferably, the three supporting parts 21 can be connected to the three column supports 241 by bolt connection or welding. There are three groups of first linear modules, and the three groups of first linear modules are respectively mounted on the mounting disc 231. Preferably, the three groups of first linear modules can be connected to the mounting disc 231 by bolt connection or welding. The three groups of first linear modules are evenly arranged along the circumferential direction of the mounting disc 231 and are spaced 120 degrees apart. The output ends of the three groups of first linear modules are respectively connected to the three column supports 241.

[0073] The driving part 24 provided in this example is composed of a column support 241 and a first linear module. The column support 241 is connected to the support part 21. The first linear module is installed on the mounting disc 231 and the output end of the first linear module is connected to the column support 241. The three column supports 241 are driven to move along the first linear module by the three first linear modules. Since the column support 241 is connected to the support part 21, the three support parts 21 can be moved relative to the mounting disc 231 and toward or away from the center of the mounting disc, thereby adjusting the distance between the three support parts 21. At the same time, due to the stability and high precision of the linear module operation, the distance between the three support parts 21 can be further accurately adjusted.

[0074] In order to achieve sliding cooperation between the support part and the clamping part, in this embodiment, the support part 21 preferably includes a slide rail column 211; a slider bearing 212, the slider bearing 212 is slidably installed on the slide rail column 211 and the slider bearing 212 is connected to the clamping part 22, specifically, the slide rail bearing 212 can be fixedly connected to the clamping part 22 by bolt connection or welding.

[0075] The support part 21 provided in this embodiment is composed of a slide rail column 211 (the slide rail column 211 can be a structure in which a linear guide rail is arranged on the column) and a slide rail bearing 212. The slide rail bearing 212 is slidably matched with the slide rail column 211, and the slide rail bearing 212 is connected to the clamping part 22. Since the slide rail bearing 212 can slide along the slide rail column 211 and the slide rail bearing 212 is connected to the clamping part 22, the movement of the slide rail bearing 212 can drive the clamping part 22 to slide relative to the support part 21. At the same time, since the guide rail on the slide rail column 211 is a linear guide rail, and the slide rail column 211 is perpendicular to the mounting disc 231, the magnetic levitation rotor power system 1 can be more accurately limited to perform linear motion along its axial direction (Y axis).

[0076] In order to realize the movement constraint of the upper part of the support part, in this embodiment, preferably, the constraint part 25 includes: a first connecting member 251, the first connecting member 251 is installed on the upper part of the support part 21; a first constraint rod 252, the two ends of the first constraint rod 252 are respectively provided with a first long hole 253 and a first connection hole 254, there are at least two first constraint rods 252, one end of the first connecting member 251 is detachably connected to the end of one of the first constraint rods 252 having the first long hole 253, and the other end is rotatably connected to the end of another first constraint rod 252 having the first connection hole 254.

[0077] Specifically, there are three first connecting members 251, and the three first connecting members 251 can be fixedly connected to the upper ends of the three slide rail columns 211 by bolt connection respectively. There are three first restraining rods 252, and as shown in FIG. Figure 5 As shown, in a clockwise direction, the three first connecting members 251 are respectively a first connecting member a2511, a first connecting member b2512 and a first connecting member c2513, and the three first restraining rods 252 are respectively a first restraining rod a2521, a first restraining rod b2522 and a first restraining rod c2523. One end of the first connecting member a2511 can be rotatably connected to the end of the first restraining rod a2521 having the first connecting hole 254 via a pin, and the other end of the first connecting member a2511 can be detachably connected to the end of the first restraining rod b2522 having the first elongated hole 253 via a bolt.

[0078] One end of the first connecting member b2512 can be rotatably connected to the end of the first restraining rod b2522 having the first connecting hole 254 via a pin, and the other end of the first connecting member b2512 can be detachably connected to the end of the first restraining rod c2523 having the first elongated hole 253 via a bolt.

[0079] One end of the first connecting member c2513 can be rotatably connected to the end of the first constraint rod c2523 having the first connecting hole 254 through a pin shaft, and the other end of the first connecting member c2513 can be detachably connected to the end of the first constraint rod a2521 having the first long hole 253 through a bolt.

[0080] The constraint part 25 provided by this scheme consists of a first connecting member 251 and a first constraint rod 252. The first connecting member 251 is installed on the upper part of the support part 21. The first elongated hole 253 and the first connecting hole 253 are respectively provided at both ends of the first constraint rod 252. The first connecting member 251 is connected to the first constraint rod 252 at both ends. One end of the first connecting member 251 is rotatably connected to the first connecting hole 253 of one of the first constraint rods 252, and the other end is detachably connected to the first elongated hole 253 of the other first constraint rod 252. Since one end of the first connecting member 251 is rotatably connected to the first connecting hole 254 and the other end is detachably connected to the first elongated hole 253, when the support part 21 moves, the first connecting member 251 can be driven to move relative to the first constraint rod 252 in the first elongated hole 253. When the support part 21 moves into place, the first connecting member 251 can be fixed in the first elongated hole 253 through the detachable connection, thereby limiting the movement of the first constraint member 252, thereby realizing the constraint of the upper part of the support part.

[0081] Example 3

[0082] The same parts of this embodiment as those of embodiment 1 are not described here in detail. The difference between this embodiment and embodiment 1 is that Figure 6-8As shown, the driving portion 24 includes: an adjusting dial 241', the adjusting dial 241' is rotatably mounted on the mounting portion 23, specifically, the adjusting dial 241' can be rotatably connected to the mounting disc 231 through a rotating shaft; a first connecting rod 242', one end of the first connecting rod 242' is rotatably mounted on the adjusting dial 241', and the other end is mounted on the support portion 21; specifically, there are three first connecting rods 242', one end of the three first connecting rods 242' can be rotatably connected to the adjusting dial 241' through a rotating pair, the other ends of the three first connecting rods 242' can be respectively rotatably connected to the three supporting portions 2 through a rotating pair, or the other ends of the three first connecting rods 242' can be respectively rotatably connected to the three supporting portions 2 through a rotating pair. A corresponding fixed connection, the fixed connection method can effectively reduce the loss caused by the rotation of the rotating pair; the second connecting rod 243', one end of the second connecting rod 243' can be rotatably installed on the mounting part 23, and the other end is installed on the support part 21. Specifically, there are three second connecting rods 243', one end of the three second connecting rods 243' can be rotatably connected to the mounting disk 231 through a rotating pair, the other ends of the three second connecting rods 243' can be respectively rotatably connected to the three support parts 2 through a rotating pair, or the other ends of the three second connecting rods 243' can be respectively fixedly connected to the three support parts 2 in a one-to-one correspondence. The fixed connection method can effectively reduce the loss caused by the rotation of the rotating pair.

[0083] The driving portion 24 in this embodiment is composed of an adjusting dial 241′, a first connecting rod 242′ and a second connecting rod 243′. The adjusting dial 241′ is rotatably mounted on the mounting portion 23. One end of the first connecting rod 242′ is rotatably connected to the adjusting dial 241′ and the other end is fixedly connected to the support portion 21. One end of the second connecting rod 243′ is rotatably connected to the mounting portion 23 and the other end is rotatably connected to the support portion 21. Since the adjusting dial 241′ is rotatably connected to the mounting portion 23, the adjusting dial 241′ can be rotated relative to the mounting portion 23. Since the first connecting rod 242′ is fixedly connected to the support portion 21 and the first connecting rod 242′ is movably connected to the adjusting dial 241′, the adjusting dial 241′ can be rotated relative to the mounting portion 23. When 41′ rotates, the adjusting dial 241′ can drive the support part 21 to move through the first connecting rod 242′. At the same time, since the second connecting rod 243′ is rotatably connected to the support part 21 and the mounting part 23 respectively, the second connecting rod 243′ can limit the support part 21 to move on a circle formed with the connection between the second connecting rod 243′ and the mounting part 23 as the center and the length of the second connecting rod 243′ as the radius, that is, it moves along the trajectory of the circle. Therefore, through the linkage structure composed of the adjusting dial 241′ and the first connecting rod 242′ and the second connecting rod 243′, it is possible to simultaneously drive the three support parts 21 to be retracted and expanded by rotating the adjusting dial 241′ alone.

[0084] In order to enhance the stability of the movement of the support part, this embodiment further includes the driving part 24: a first slide groove 244′, the first slide groove 244′ is installed on the mounting part 23, the shape of the first slide groove 244′ is arc-shaped, the center of the arc is the connection between the second connecting rod 243′ and the mounting part 23, and the radius of the arc is the length of the second connecting rod 243′; a first ball 248′, the first ball 248′ is installed on the support part 21, and the first ball 248′ is slidably matched with the first slide groove 244′, and there are three specific first slide grooves 244′, and the three first slide grooves 244′ can be fixedly connected to the mounting disc 231 by welding respectively.

[0085] The driving portion 24 provided in this embodiment also includes a first slide groove 244′, which is installed on the mounting portion 23, and the first slide groove 244′ is arc-shaped, the center of the arc is the connection between the second connecting rod 243′ and the mounting portion 23, and the radius of the arc is the length of the second connecting rod 243′. A first ball 248′ that cooperates with the first slide groove 244′ is provided on the support portion 21. Since the shape of the first slide groove 244′ is the same as the moving trajectory of the support portion 21, and due to the sliding cooperation between the first slide groove 244′ and the first ball 248′, the support portion 21 moves more stably along the moving trajectory formed on the circumference with the connection between the second connecting rod 243′ and the mounting portion 23 as the center and the length of the second connecting rod 243′ as the radius.

[0086] In order to achieve stable positioning after the support part is adjusted, this embodiment further includes: an adjusting rod 245′, the adjusting rod 245′ is installed on the adjusting dial 241′; an adjusting locator 246′, the adjusting locator 246′ is installed on the mounting part 23; a first positioning hole 247′, the first positioning hole 247′ is installed on the adjusting locator 246′ and the first positioning hole 247′ is matched with the adjusting rod 245′.

The adjustment lever 245′ is installed on the adjustment dial 241′, the adjustment locator 246′ is installed on the mounting portion 23, and the adjustment locator 246′ is provided with a first positioning hole 247′ that cooperates with the adjustment lever 245′. The prime minister rotates the adjustment dial 241′ through the adjustment lever 245′. When the adjustment dial 241′ rotates to drive the support portion 21 to move, the adjustment lever 245′ is fixed by the cooperation of the first positioning hole 247′ and the adjustment lever 245′, thereby completing the stable positioning of the support portion after adjustment.

[0088] In order to achieve sliding cooperation between the supporting part and the clamping part, in this embodiment, preferably, the supporting part 21 includes an optical axis 211′ (the optical axis 211′ is a long cylindrical rod with a smooth surface); a ball sleeve 212′, the ball sleeve 212′ can be slidably installed on the optical axis 211′, and the ball sleeve 212′ is connected to the clamping part 22.

The first screw column 211′ and the first screw slider 212′ are slidably matched, and the first screw slider 212′ is connected to the clamping portion 22. Since the first screw slider 212′ can slide along the first screw column 211′ and the first screw slider 212′ is connected to the clamping portion 22, the movement of the first screw slider 212′ can drive the clamping portion 22 to slide relative to the support portion 21.

[0091] The constraint portion 25 provided in this embodiment is composed of a constraint fixing ring 251′ and a third connecting rod 252′. One end of the third connecting rod 252′ is rotatably connected to the constraint fixing ring 251′, and the other end is rotatably connected to the support portion 21. When the support portion 21 is moved into place, the third connecting member 252′ can be fixed to the constraint fixing ring 251′ through a detachable connection, thereby limiting the movement of the third connecting member 252′ by the constraint fixing ring 251′, thereby realizing constraint on the upper part of the support portion 21.
