[0039] like Fig. 9 As shown, the first lifting cylinder 28 is fixedly connected to the middle part of the upper surface of the support platform 2, and the first lifting cylinder 28 supports and fixes the lifting device; the second lifting cylinder 29 can be slidably connected to the inner wall of the first lifting cylinder 28 up and down; the function of the first motor 25 is to provide a rotating force for the long threaded rod 26, and the motor is a prior art and will not be described in detail; the threaded seat 27 is fixedly connected to the lower end of the outer surface of the second lifting cylinder 29, and when the long threaded rod 26 rotates, it can drive the threaded seat 27 and the second lifting cylinder 29 upward or downward through the threaded connection with the threaded seat 27 Movement; when the first motor 25 is started, it can drive the corresponding long threaded rod 26 to rotate. When the long threaded rod 26 rotates, it can drive the threaded seat 27, the second lifting cylinder 29, the box 34, etc. to move upward or downward, so that the box 34 and the detector 45 reach the specified position, and the threaded connection between the long threaded rod 26 and the threaded seat 27 has a self-locking function, that is, when the long threaded rod 26 does not rotate, the corresponding threaded seat 27, the second lifting cylinder 29, and the box 34 are in a fixed height, which can provide stable support for the box 34.

[0040] The third lifting cylinder 30 is slidably connected to the inner wall of the upper end of the second lifting cylinder 29, and the box body 34 is fixedly connected to the upper end surface of the third lifting cylinder 30; the middle inner wall of the second lifting cylinder 29 is rotatably connected to two symmetrically distributed first spur gears 32, and the outer ends of the two first spur gears 32 are respectively meshed with first spur racks 31 fixedly connected to the first lifting cylinder 28, and the inner ends of the two first spur gears 32 are respectively meshed with second spur racks 33 fixedly connected to the third lifting cylinder 30.

Similarly, the third lifting cylinder 30 can only slide up and down on the inner wall of the second lifting cylinder 29 and cannot rotate; the first spur rack 31, the first spur gear 32, and the second spur rack 33 are installed and shaped as shown in FIG. Fig. 9 As shown, the first spur gear 32 is rotatably connected to the inner wall of the second lifting cylinder 29 through a rotating shaft, the first spur rack 31 is fixedly connected to the inner wall of the upper end of the first lifting cylinder 28, and the second spur rack 33 is fixedly connected to the inner wall of the lower end of the third lifting cylinder 30; when the long threaded cylinder 38 rotates, it can drive the corresponding threaded seat 27 and the second lifting cylinder 29 to move upward, and when the second lifting cylinder 29 moves upward, it will drive the first spur gear 32 to move upward. When the first spur gear 32 moves upward, it will mesh with the first spur rack 31, which will cause the first spur gear 32 to rotate. When the first spur gear 32 rotates, it will mesh with the second spur rack When the bar 33 is engaged, the second spur rack 33, the third lifting cylinder 30, and the box 34 will move upward, thereby driving the box 34 to move upward to the specified position. When the long threaded rod 26 is reversed, the third lifting cylinder 30, the box 34, etc. can be moved downward. The principle is the same and will not be repeated here. By setting up a multi-stage lifting device, the box 34 can be raised higher or lowered to a lower end. The multi-stage lifting device does not take up space when folded. A handle 3 is fixed on the outer surface of the first lifting cylinder 28. The function of the handle 3 is to facilitate the movement of the entire device and to facilitate the control and adjustment of the flatness of the support platform 2.

[0042] Three evenly distributed limit rods 10 are fixedly connected to the outer side of the upper end surface of the round base 1, and the adjusting threaded rods 12 are slidably connected to the corresponding outer surfaces of the limit rods 10.

The outer surfaces of the limit rods 10 are respectively covered with first springs 14, and the lower end surfaces of the adjusting threaded rods 12 are respectively fixedly connected with circular ring pads 13 that match the first springs 14.

[0043] like Figure 3-Figure 4As shown, the adjusting threaded rod 12 can be slidably connected to the outer surface of the limit rod 10 up and down, and cannot rotate under the limit of the limit rod 10. The upper end surface of the limit rod 10 is also fixed with an anti-drop cap 11, which is slidably connected to the inner wall of the adjusting threaded rod 12. The anti-drop cap 11 can prevent the adjusting threaded rod 12 from being separated from the limit rod 10; the installation and shape of the ball seat 16 and the ball pin 15 are as shown Figure 3 As shown, the inner wall of the ball seat 16 is provided with a concave hole matched with the ball pin 15, and the ball pin 15 can be rotated or turned over on the inner wall of the concave hole, which is equivalent to a ball hinge. The three adjusting threaded rods 12 are respectively ball-hinged with the support platform 2. The principle of three points determining a plane is used. When the height of the three adjusting threaded rods 12 changes, the angle of the support platform 2 and the height can be adjusted slightly. Even if the support platform 2 is tilted forward and backward or left and right, the support platform 2 can be adjusted with multiple degrees of freedom so that the support platform 2 is adjusted to a vertical state with the ground; the installation and shape of the annular pad 13 and the first spring 14 are as shown in Figure 4 As shown, one end of the first spring 14 is fixedly connected to the upper surface of the round base 1, and the other end of the first spring 14 is fixedly connected to the lower surface of the circular ring pad 13. The first spring 14 always has an upward thrust on the circular ring pad 13, even if the corresponding adjusting threaded rod 12 is in the topmost state under normal conditions. When in use, after the round base 1 is placed in the specified position, when the round base 1 encounters an uneven ground, the support platform 2 is in an inclined state at this time, and the support platform 2 is adjusted by driving the handle 3, that is, the high end position of the support platform 2 is pressed down, that is, the height of the corresponding adjusting threaded rod 12 will change, compressing the corresponding first spring 14, and after the support platform 2 is adjusted to a horizontal state, the adjusting threaded rod 12 can be fixed by the locking mechanism at this time to limit the upward or downward movement of the adjusting threaded rod 12, and the support platform 2 can be fixed at this time. After the support platform 2 is fixed, the device is in a stable state and can be used normally. By manually adjusting the support platform 2, multiple angles can be adjusted simultaneously, and the support platform 2 can be leveled conveniently and quickly.

[0044] The locking mechanism includes a support tube 4 fixed to the round base 1, and the inner wall at the center of the support tube 4 is rotatably connected to the transmission shaft 60. The inner wall of the support tube 4 is also provided with a coil spring 5, one end of the coil spring 5 is fixed to the transmission shaft 60, and the other end of the coil spring 5 is fixed to the support tube 4. A first disc 6 is fixed to the upper end of the outer surface of the transmission shaft 60, and three evenly distributed first connecting rods 7 are hinged at the non-center of the upper end surface of the first disc 6. Three evenly distributed support seats 9 are fixed to the upper end surface of the round base 1, and the upper end surfaces of the support seats 9 are respectively slidably connected to threaded locking blocks 8 that cooperate with the adjusting threaded rod 12, and the outer ends of the first connecting rods 7 are respectively hinged to the corresponding threaded locking blocks 8.

[0045] like Figure 3-Figure 5As shown, the support cylinder 4 is used to support the transmission shaft 60 and the coil spring 5. The function of the coil spring 5 is to drive the transmission shaft 60 to have a driving force, that is, to drive the first disc 6 to have a rotational force; the support seat 9 is used to support the corresponding thread locking block 8, so that the thread locking block 8 can only slide inward or outward. The bolt locking block is installed and shaped as shown in FIG. Figure 4 As shown, when the thread locking block 8 moves outward to contact and engage with the corresponding adjusting threaded rod 12, the thread locking block 8 will limit the upward or downward movement of the adjusting threaded rod 12, thereby limiting and fixing the height of the adjusting threaded rod 12; when the thread locking block 8 moves inward to a specified position, that is, after the thread locking block 8 and the adjusting threaded rod 12 are disengaged, the thread locking block 8 no longer limits the upward and downward movement of the adjusting threaded rod 12, that is, the adjusting threaded rod 12 can return to normal at this time; the installation and shape of the first connecting rod 7 and the first disc 6 are as shown in FIG. Figure 5 As shown, when the first disk 6 rotates, it can drive the inner end of the first connecting rod 7 to rotate in a circle, and the outer end of the first connecting rod 7 will drive the corresponding threaded locking block 8 to move synchronously inward or outward; when the threaded locking block 8 moves outward, that is, the threaded locking block 8 is engaged with the adjusting threaded rod 12, and the locking mechanism is opened at this time, limiting the up and down movement of the adjusting threaded rod 12 to fix the support platform 2, and when the outer end of the first connecting rod 7 drives the threaded locking block 8 to move inward, that is, the corresponding threaded locking block 8 moves inward to disengage from the adjusting threaded rod 12, and the adjusting threaded rod 12 can be reset to its initial state at this time, that is, the locking mechanism is closed; under the winding force of the winding spring 5, the three threaded locking blocks 8 can have a driving force always toward the outside, so that the threaded locking block 8 is stably engaged with the adjusting threaded rod 12, that is, the support platform 2 is fixed.

[0046] A linkage spur gear 17 is fixedly connected to the middle part of the outer surface of the transmission shaft 60, and three linkage spur racks 18 that are evenly distributed and staggered up and down are meshed on the outer surface of the linkage spur gear 17. Three evenly distributed expansion seats 19 are slidably connected to the inner wall of the round base 1, and the linkage spur racks 18 are fixedly connected to the corresponding expansion seats 19 respectively.

[0047] like Figure 7-Figure 8 As shown, the expansion seat 19 can slide inward or outward on the inner wall of the round base 1, and the linkage spur rack 18 and the linkage spur gear 17 are installed and shaped as shown in FIG. Figure 6 or Figure 7As shown, the linked spur rack 18 meshes with the linked spur gear 17 by being staggered up and down, which can prevent the movement from interfering with the base 1. When the expansion seat 19 moves outward to the top and unfolds, it can provide a safety barrier for the round base 1 to prevent the round base 1 from falling to one side. Under the self-winding force of the coil spring 5, the corresponding linked spur gear 17 can have a rotational force, so that the corresponding linked spur rack 18 and the expansion seat 19 are at the outermost end under normal conditions, providing safety protection for the round base 1 under normal conditions during use. When the expansion seat 19 moves inward, It will drive the corresponding linked spur rack 18 to move inward, and drive the linked spur gear 17 to rotate. The rotation of the linked spur gear 17 will drive the transmission shaft 60, the coil spring 5, and the first disc 6 to rotate. When the first disc 6 rotates, it will drive the corresponding threaded locking block 8 to move inward, that is, it will disengage from the adjusting threaded rod 12. At this time, the adjusting threaded rod 12 is no longer restricted and can be reset. After the expansion seat 19 moves inward to the bottom, it will enter the inner wall of the round base 1. At this time, it occupies less space, which reduces the space occupancy rate when stored.

[0048] The inner wall of the round base 1 is also fixedly connected with three evenly distributed square cylinders 23, and the inner walls of the bottom ends of the square cylinders 23 are slidably connected with wedge-shaped blocks 21. The upper end surfaces of the expansion seat 19 are respectively provided with grooves 20 that match the wedge-shaped blocks 21. The upper end surfaces of the wedge-shaped blocks 21 are respectively fixedly connected with first pull rods 22 that are slidably connected with the square cylinders 23. The outer surfaces of the first pull rods 22 are respectively covered with second springs 24 that match the wedge-shaped blocks 21. The upper ends of the outer surfaces of the three first pull rods 22 are fixedly connected with a triangular connecting rod 59.

[0049] like Figure 7-Figure 8As shown, the expansion seat 19 can slide on the inner wall of the round base 1, the wedge-shaped block 21 and the first pull rod 22 can be slidably connected to the inner wall of the square tube 23 up and down, one end of the second spring 24 is respectively fixed to the upper end surface of the square tube 23, and the other end is respectively fixed to the upper end surface of the wedge-shaped block 21. The second spring 24 always has a downward driving force on the wedge-shaped block 21, so that the wedge-shaped block 21 is in the bottom state under normal conditions. The outer side of the lower end surface of the wedge-shaped block 21 is respectively provided with an inclined surface, which can make the corresponding expansion seat 19 slide inward in one direction; through the triangular connecting rod 59, When the triangular connecting rod 59 is driven to move upward, the corresponding first pull rod 22 and the wedge-shaped block 21 can be driven to move upward synchronously; when the expansion seat 19 moves from the outside to the inside to retract and reset, the corresponding multiple thread locking blocks 8 will move inward, that is, the thread locking blocks 8 will be separated from the adjusting threaded rod 12, and the adjusting threaded rod 12 will be reset under the elastic force of the first spring 14. When the expansion seat 19 moves inward to meet the wedge-shaped block 21, the expansion seat 19 will move the wedge-shaped block 21 upward under the action of the inclined surface of the wedge-shaped block 21, that is, the wedge-shaped block 21 presses The second spring 24 is compressed and enters the inner wall of the square tube 23. When the expansion seat 19 moves inwardly to completely enter the inner wall of the round base 1, the slot 20 will meet the wedge-shaped block 21. At this time, the wedge-shaped block 21 will move downward and reset under the elastic force of the second spring 24, that is, the wedge-shaped block 21 enters the inner wall of the slot 20. When the wedge-shaped block 21 is engaged with the slot 20, it will limit the corresponding expansion seat 19 from moving outward, that is, it will also limit the thread lock block 8 from moving outward. At this time, the thread lock block 8, the expansion seat 19, etc. are in a stable state, that is, the locking mechanism is in a stable state. closed state; when it needs to be opened for use again, by placing the round base 1 on the ground, adjusting the support platform 2 to a horizontal position, the triangular connecting rod 59 is driven upward to enable the first pull rod 22 and the wedge-shaped block 21 to move upward. When the wedge-shaped block 21 moves upward to the top position, the wedge-shaped block 21 is disengaged from the slot 20. At this time, the expansion seat 19 and the threaded locking block 8 will move outward and reset under the winding force of the coil spring 5, that is, the adjusting threaded rod 12 is locked again, and the expansion seat 19 moves outward to provide safety for the round base 1.

[0050] The front side of the inner wall at the bottom end of the box body 34 is fixedly connected to the second motor 36, the first threaded rod 37 is fixedly connected to the output end of the second motor 36, the inner wall at the bottom end of the box body 34 is slidably connected to a long slide 39, the middle part of the upper end surface of the long slide 39 is fixedly connected to a threaded cylinder 38 threadedly connected to the first threaded rod 37, the left and right sides of the upper end surface of the long slide 39 are respectively fixedly connected to vertical plates 40, the inner wall at the lower end of the vertical plate 40 is respectively slidably connected to the second sliding pin 51, and the lower sides of the inner walls at the left and right ends of the box body 34 are respectively fixedly connected to the second The guide plate 50 and the second guide plate 50 are respectively provided with second guide grooves matching with the second sliding pin 51. The first guide rods 57 are respectively fixedly connected to the front and rear ends of the left and right sides of the inner wall of the bottom end of the box body 34. A connecting rod 55 is sleeved on the outer surface of the two first guide rods 57. The connecting rods 55 are respectively provided with transverse key grooves 56 matching with the second sliding pin 51. The front sides of the left and right end surfaces of the connecting rods 55 are respectively hinged with short connecting rods 58, and the other ends of the short connecting rods 58 are respectively hinged on the sealing door 35.

[0051] like Figure 11-Figure 15 As shown, the first threaded rod 37 is rotatably connected to the inner wall of the box body 34, and the function of the second motor 36 is to provide a rotating force for the second threaded rod; the long slide plate 39 can be slidably connected to the inner wall of the bottom end of the box body 34 forward and backward; through the threaded connection between the threaded cylinder 38 and the first threaded rod 37, the threaded cylinder 38 and the long slide plate 39 can be driven to move forward or backward when the first threaded rod 37 rotates, and the threaded connection between the first threaded rod 37 and the threaded cylinder 38 has a self-locking function, that is, when the first threaded rod 37 does not rotate, the corresponding positions of the threaded cylinder 38 and the long slide plate 39 are in a fixed state, that is, the support plate 44 and the sealing door 35 can be fixed after moving to the specified position; the lower ends of the vertical plates 40 are respectively provided with open grooves 54, and the second sliding pins 51 can be slidably connected to the inner walls of the open grooves 54 up and down, respectively, and the first guide rod 57, the linkage rod 55, the horizontal key groove 56, the short connecting rod 58, and the sealing door 35 are installed and shaped as shown in the figure Fig.15 As shown, the linkage rod 55 can be slidably connected to the outer surface of the first guide rod 57 up and down, the first guide rod 57 can limit the linkage rod 55 to move only up and down, the transverse key groove 56 can provide a space for the second sliding pin 51 to move forward and backward, and when the second sliding pin 51 moves up or down, it can drive the linkage rod 55 to move up or down. Through the hinge connection between the short connecting rod 58 and the sealing door 35, when the linkage rod 55 moves downward, it can drive the sealing door 35 to flip to the front side of the lower end, so that the sealing door 35 is flipped to a horizontal state, forming a placement table, and the box body 34 is opened; the installation and shape of the second guide plate 50, the second guide groove, and the second sliding pin 51 are as shown in the figure. Fig.14As shown, the second guide groove includes a second transverse groove 52 and a second inclined groove 53. When the second sliding pin 51 moves forward, it will engage with the second inclined groove 53, which will cause the second sliding pin 51 to move downward. After the second sliding pin 51 moves downward to the bottom, the second sliding pin 51 continues to move forward and enters the inner wall of the second transverse groove 52. The second sliding pin 51 no longer moves downward, and at this time, it will horizontally follow the vertical plate 40 to move forward. Therefore, when the second motor 36 is started, the corresponding first threaded rod 37 can be driven to rotate. When the first threaded rod 37 rotates, it will drive the long slide 39, the vertical plate 40, the second sliding pin 51, etc. to move forward synchronously. When the second sliding pin 51 moves forward, When the second sliding pin 51 is moved, it will engage with the second inclined groove 53, which will cause the second sliding pin 51 and the connecting rod 55 to move downward synchronously. When the connecting rod 55 moves downward, the sealing door 35 will be driven to flip downward. When the vertical plate 40 and the second sliding pin 51 move forward to make the second sliding pin 51 enter the inner wall of the second transverse groove 52, the second sliding pin 51 moves downward to the lowest end position, and the corresponding connecting rod 55 moves downward to the lowest end position. At this time, the corresponding sealing door 35 flips downward to a horizontal state, that is, the box body 34 is in a fully opened state. At this time, when the vertical plate 40, the second sliding pin 51, etc. continue to move forward, the corresponding sealing door 35 is in the specified position and no longer moves.

[0052] The upper sides of the outer end surfaces of the two vertical plates 40 are respectively hinged with main connecting rods 41, and the outer end surfaces of the vertical plates 40 are also hinged with secondary connecting rods 42 that are parallel to and of the same length as the main connecting rods 41. L-shaped frames 43 are respectively fixed to the surfaces of the left and right ends of the support platform, and the L-shaped frames 43 are respectively hinged to the corresponding main connecting rods 41 and secondary connecting rods 42. The inner walls of the main connecting rods 41 are also respectively fixed with first sliding pins 46. The middle parts of the inner walls of the left and right ends of the box body 34 are respectively fixed with first guide plates 47, and the first guide plates 47 are respectively provided with first guide grooves that cooperate with the first sliding pins 46.

[0053] like Figure 11-13 As shown, the main connecting rod 41, the secondary connecting rod 42, the L-shaped frame 43, and the vertical plate 40 form a parallelogram mechanism, which can keep the L-shaped frame 43 parallel to the vertical plate 40, that is, the support plate 44 and the detector 45 are always in a horizontal state; the installation and shape of the first guide plate 47 and the first sliding pin 46 are as shown in FIG. Fig.13As shown, the first guide groove includes a first transverse groove 48 and a first inclined groove 49. When the vertical plate 40, the main connecting rod 41, the first sliding pin 46, etc. move forward, that is, when the first sliding pin 46 is engaged with the first transverse groove 48, the vertical plate 40 and the main connecting rod 41 will not change their angles, that is, they will drive the corresponding L-shaped frame 43, the support plate 44, and the detector 45 to move horizontally forward. When the vertical plate 40, the main connecting rod 41, the first sliding pin 46, etc. move forward to make the first sliding pin 46 enter the inner wall of the first inclined groove 49, the first sliding pin 46 will move upward under the engagement of the first inclined groove 49, and at this time, the corresponding main connecting rod 41 will be driven to swing upward. When the main connecting rod 41 swings upward, the support plate 44 will move horizontally to the front side of the upper end under the limit of the secondary connecting rod 42, so that the detector 45 The detector 45 moves to the specified position; through the engagement of the first guide plate 47 and the first sliding pin 46, and the second guide plate 50 and the second sliding pin 51, when the vertical plate 40 moves forward, it can drive the corresponding sealing door 35 to flip and open to the lower side of the front end first, and flip to a horizontal state to form a placement table. When the vertical plate 40 continues to move forward, the support plate 44 and the detector 45 can be moved forward. Even after the support plate 44 and the detector 45 move forward to the outside of the box body 34, they will flip upward and move horizontally, and the support table and the detector 45 always remain in a horizontal state, which is convenient for users to detect and operate. When the second motor 36 is started to reverse the first threaded rod 37, the device can be reset to the initial state, which will not be repeated; and the movement of the sealing plate and the support plate 44 will not interfere with each other.

[0054] When the present invention is in use, after the round base 1 is placed on the ground, the support platform 2 can be leveled by the provided parallel adjustment device when encountering an uneven ground. Since the box 34 and the detector 45 need to be moved upward to the specified position, if the support platform 2 is not in a parallel state, the center of gravity of the box 34 and the detector 45 will continue to rise when moving upward, which will cause the entire device to tilt to one side and break; therefore, the support platform 2 can be leveled by the provided parallel adjustment device, so that when the box 34, the detector 45, etc. move upward, the center of gravity is always at the upper end of the support platform 2, thereby improving the stability of the device when in use; by the provided long threaded rod 26, the corresponding box 34 and the detector 45 can be driven to move upward to the specified position when the long threaded rod 26 rotates, according to the needs of the electrician. The round base 1 is used to contact the ground, that is, to support the support platform 2. By setting a plurality of adjusting threaded rods 12 that can move up and down, the support platform 2 can be quickly leveled with multiple degrees of freedom, so that the box 34 and the detector 45 can be in a stable state after rising to the specified position; by the setting of the locking mechanism, after the support platform 2 is leveled, the locking mechanism is opened, and the adjusting threaded rod 12 can be limited and fixed, thereby limiting and fixing the support platform 2 after leveling, so that the support platform 2 is in a stable state; by the setting of the placement slot, electronic components can be loaded, and the zipper can seal the placement slot to prevent the electronic components from falling. After detecting that a certain electronic device is damaged, the zipper can be opened to take out the electronic component inside the placement slot and replace it directly, so as to complete the emergency repair work in a race against time.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
