DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1-10 The embodiment of the present invention provides an electronic experiment simulation training test bench, comprising a height power unit 12 and two stand brackets, wherein the movable parts of the two stand brackets are connected to each other via the height power unit 12, and the height power unit 12 pulls the two stand brackets to change height together;

[0034] The stand frame comprises a hollow column 13 which is hollow inside and open on the top, a hollow column 2 14 is displaceably installed between the inner walls of the hollow column 13, an experimental table 11 is installed on the top of the hollow column 2 14, a training platform 111 is installed on the experimental table 11, a box body 112 is installed below the experimental table 11, a plurality of vertically arranged drawers 113 are displaceably connected in the box body 112, the top of the box body 112 is recessed so that structural parts can pass through and experimental training can be carried out through the training platform 111, one end of the hollow column 2 14 passes through the open part on the top of the hollow column 13, a leg unit 15 which can be extended to change the length is fixedly connected to the bottom of the hollow column 13, a threaded circular shell 16 is fixedly connected to the middle area of ​​the lower wall of the hollow column 13 at a 90-degree angle, the upper wall of the hollow column 2 14 is screwed to the hollow inside and is open on the bottom. The screw 17 is embedded in the threaded circular shell 16 and is screwed with the threaded circular shell 16. The lower wall of the hollow column 13 is screwed with a rotating column 18. The rotating column 18 is located in the threaded circular shell 16 and embedded in the screw 17. The surface of the rotating column 18 is fixedly connected with a plurality of discs 19 with reserved teeth on the wall at the same intervals along the installation direction. The disc 19 is located in the screw 17. The screw 17 is fixedly connected with a bite ring 120 that bites with the disc 19 below. The inner wall of the bite ring 120 is reserved with teeth arranged at the same intervals. The span between the two discs 19 that are close to each other exceeds the span at both ends of the bite ring 120. A length power unit 121 that pulls the leg unit 15 to extend out of the length change is installed in the leg unit 15. The length power unit 121 and the rotating column 18 are connected to each other.

[0035] The up-down power unit 12 and the lead screw 17 are connected to each other. The up-down power unit 12 pulls the lead screw 17 to rotate and pull the hollow column 2 14 to move up and down along the hollow column 13, and the pulling engagement ring 120 engages with each disk body 19 in sequence.

[0036] By installing a lead screw 17 inside the stage support frames on both sides and pulling them together through a separate height power unit 12, the height change of the two stage support members can be achieved together, ensuring the stability of the experimental table 11 during the height displacement, and during the height displacement of the lead screw 17 and the hollow column 14, the multiple disks 19 on the surface wall of the rotating column 18 can be engaged with the bite ring 120 in sequence, so that the lead screw 17 pulls the bite ring 120 to rotate, and the bite ring 120 can pull the disk 19 to rotate, thereby pulling the length power unit 121 pulls the support leg unit 15 to extend the length change, so as to achieve the change of the span at both ends of the support leg unit 15, thereby ensuring that when the vertical position of the test table 11 changes, the support leg unit 15 can adaptably adjust the span at both ends, so as to ensure the balance and stability of the test table 11 during use in various vertical positions, and the span between the two plates 19 installed close to each other exceeds the span at both ends of the bite ring 120, so that there is a transmission gap during the rotation of the bite ring 120, so that the support leg unit 15 only needs to be moved once in the set vertical range.

[0037] The support leg unit 15 includes a hollow fixed connection module 152, and the length power unit 121 is installed in the fixed connection module 152. The two ends of the fixed connection module 152 are connected to the supporting module 153 for displacement. The cross-section of the supporting module 153 is a right angle, and a friction plate is installed at the end of the supporting module 153 that touches the lower wall.

[0038] The supporting module 153 can be displaced along the fixing module 152 under the traction of the length power unit 121 to achieve the purpose of changing the length of the probe, and the friction plate can make the support leg unit 15 placed more firmly.

[0039] The long-short power unit 121 includes a rod body 1212, the wall of the rod body 1212 is provided with threads, one end of the rod body 1212 is fixedly connected to the rotating column 18, the surface of the rod body 1212 is engaged with two disk bodies 1213 with threads reserved on the wall, the two disk bodies 1213 are fixedly connected to the rotating column 1214, the two rotating columns 1214 are fixedly connected to the lead screw 1215 at one end farther away from each other in a mirror-image manner, the two lead screws 1215 are respectively threadedly connected to the two supporting modules 153, and a fixing platform for supporting the two rotating columns 1214 is installed in the fixing module 152.

[0040] The rod body 1212 rotates in coordination with the rotating column 1214, thereby pulling the disk body 1213 and the screw 1215 on both sides to rotate, and then achieving the change in the extension length of the supporting module 153 at both ends of the support leg unit 15. Moreover, during the use of the support leg unit 15, the mutual locking effect between the supporting module 153 and the screw 1215 can ensure the stability of the supporting module 153, and there will be no movement on both sides during use.

[0041] A connecting ring 1216 is installed on the inner wall of the assembly opening of the second disk body 1213, and a protruding strip is installed on the surface of the second rotating column 1214. A recessed opening that matches the protruding strip is reserved in the connecting ring 1216. The connecting ring 1216 and the second rotating column 1214 are displacement-connected. An assembly frame 1217 is fixedly connected between the surfaces of both ends of the connecting ring 1216. One side of the assembly frame 1217 is fixedly connected to a connecting rod 1218. One end of the connecting rod 1218 passes through the side wall of the fixed connection module 152. The side wall of the fixed connection module 152 is reserved with a through sliding opening that matches the connecting rod 1218. The connecting rod 1218 moves along the through sliding opening to pull the assembly frame 1217, the connecting ring 1216 and the second disk body 1213 to move, so that the second disk body 1213 and the second rod body 1212 are separated and not bitten.

[0042] When only the supporting module 153 at one end of the leg unit 15 needs to be extended to change its length or to maintain the shape of the leg unit 15, one or two connecting rods 1218 can be pulled to separate the disk body 1213 and the rod body 1212. As a result, the rotation of the rod body 1212 cannot pull the disk body 1213 to rotate, so that the leg unit 15 cannot be extended to change its length, thereby ensuring the stability of the overall span of the leg unit 15.

[0043] The connecting rod 1218 is threadedly connected to a ring body 1219 with reserved threads inside through one end surface of the fixing module 152, and the ring body 1219 and the side wall of the fixing module 152 are in contact with each other.

[0044] The connecting rod 1218 can be constrained and stabilized by the mutual contact between the ring body 1219 and the side wall of the fixed connection module 152, thereby maintaining the stability of the position of the second disk body 1213.

[0045] The hollow column 14 is installed on the surface of the threaded circular shell 16. The inner wall of the hollow column 14 and the surface of the threaded circular shell 16 touch each other. The surface of the hollow column 14 and the inner wall of the hollow column 13 touch each other. During the displacement of the hollow column 14, the hollow column 14 is always installed on the surface of the threaded circular shell 16.

[0046] When the hollow column 14 is displaced upward, the load distribution inside and outside the hollow column 14 can be ensured to be balanced. When bearing very high radial force, since the inner and outer walls of the hollow column 14 are both positioned and constrained, sufficient supporting force can be obtained, thereby preventing the hollow column 14 from being offset or deformed, thereby enhancing the ability of the hollow column 14 to offset torsion.

[0047] A restraining rod 142 is arranged on the outer wall of the second hollow column 14 along the installation direction, and a stop opening 132 adapted to the restraining rod 142 is reserved on the inner wall of the first hollow column 13 .

[0048] The cooperation between the restraining rod 142 and the stop opening 132 can ensure corresponding rotation between the threaded round shell 16 and the second hollow column 14, and during the rotation of the threaded round shell 16, the stability of the second hollow column 14 can be ensured, effectively suppressing the swinging phenomenon.

[0049] The high and low power unit 12 includes a rotating rod 122, a gearbox 123 and a motor 124. The two ends of the rotating rod 122 that are far away from each other respectively pass through the side walls of two hollow columns 14 and are fixedly connected to an umbrella plate 125 with a toothed surface reserved on the wall. An umbrella plate 126 with a toothed surface reserved on the wall and engaged with the umbrella plate 125 is installed on the lead screw 17. The gearbox 123 is installed on the surface wall of the rotating rod 122. The power end of the gearbox 123 and the rotating rod 122 are connected to each other, and the power end of the motor 124 and the gearbox 123 are connected to each other. A supporting seat 127 is installed on the side wall of a hollow column 14, and the supporting seat 127 and the motor 124 are connected to each other.

[0050] During the height change, the motor 124 can pull the umbrella plate 1 125 on both sides to rotate together, and the umbrella plate 2 126 on both sides can pull the two lead screws to rotate together, so as to achieve the purpose of changing the height of the two stand brackets together.

[0051] The high and low power unit 12 also includes an embedding part 128, which includes a suction piece 1282 and a right-angle embedding platform 1283 that is embedded and cooperates with the umbrella plate 125 and the umbrella plate 2 126. The suction piece 1282 is arranged on the upper part of the inside of the hollow column 2 14. The suction piece 1282 includes an outer shell, and an iron core and a coil are arranged inside the outer shell. The coil is connected to the outer circumference of the iron core. The suction piece 1282 and the motor 124 are controlled by a connection button, and the right-angle embedding platform 1283 and the suction piece 1282 are attracted to each other. The upper part of the inside of the hollow column 2 14 is connected to the fixed rod 1284 at a ninety-degree angle, and the right-angle embedding platform 1283 and the fixed rod 1284 are displacement-connected.

[0052] After the height change is completed, the right-angle embedded platform 1283 can be used to lock the umbrella plate 125 and the umbrella plate 2 126 respectively, so that the lead screw can be constrained to prevent rotation, thereby ensuring the stability of the vertical position, and there is no need to constantly execute the constraint through the motor 124, so that the motor 124 is not prone to failure and can be used for a long time. When the height change is required, the right-angle embedded platform 1283 can be pulled and displaced through the suction piece 1282, thereby separating the right-angle embedded platform 1283 and the umbrella plate 125 and the umbrella plate 2 126. The release is convenient and quick, and the operator does not need to perform other actions to release.

[0053] A spiral beryllium copper wire 1285 is installed on the surface wall of the solid connecting rod 1284, and the spiral beryllium copper wire 1285 is located between the right-angle embedded platform 1283 and the upper part of the inner side of the hollow column 14.

[0054] By installing the spiral beryllium copper wire 1285, after the suction component 1282 is powered off, the right-angle embedded platform 1283 can be moved to the original position due to the mass of the main body, and can also be quickly moved to the original position with the help of the spiral beryllium copper wire 1285. The spiral beryllium copper wire 1285 also supports the right-angle embedded platform 1283 to prevent the right-angle embedded platform 1283 from separating from the umbrella plate 125 and the umbrella plate 2 126.

[0055] The specific implementation method is as follows: when the height of the experimental table 11 needs to be changed, the motor 124 and the suction member 1282 are operated by turning on the button, and the suction member 1282 has a pulling ability, thereby pulling the right-angle embedded platform 1283 to move along the fixed rod 1284, thereby releasing the umbrella plate 125 and the umbrella plate 2 126, thereby the motor 124 pulls the umbrella plate 125 to rotate through the gearbox 123, thereby pulling the two umbrella plates 126 and the lead screw 17 to rotate together, the lead screw 17 is threadedly connected to the threaded circular shell 16, and the threaded circular shell 16 is fixedly connected to the bottom of the hollow column 13, thereby the rotation of the lead screw 17 can be converted into a height displacement, pulling the hollow column 2 14 to move upward to achieve the change of the vertical position of the experimental table 11;

[0056] During the upward displacement of the hollow column 14, the lead screw 17 and the bite ring 120 move upward along the hollow column 14 and rotate together, thereby allowing the rotating column 18 to gradually protrude from under the lead screw 17, allowing the drag rod disc 19 on the surface of the rotating column 18 to engage with the bite ring 120 in sequence. During the engagement of the disc 19 and the bite ring 120, the bite ring 120 pulls the disc 19, the rotating column 18 and the rod 2 1212 to rotate, thereby pulling the discs 121 on both sides. 3. The second rotating column 1214 and the second lead screw 1215 rotate, thereby allowing the supporting modules 153 at both ends of the support leg unit 15 to extend, thereby increasing the span of the support leg unit 15, thereby ensuring the stability of the test table 11 during use in various vertical positions, and during the period when the bite ring 120 moves to the two adjacent disks 19, the rotating column 18 is not in operation, so that the test table 11 can move in one of the set multiple vertical intervals, and only needs to change the overall span of the support leg unit 15;

[0057] When one side of the test table 11 approaches the indoor wall, it means that the span of the leg unit 15 on this side does not need to be increased. During the change of vertical position, the operator first rotates the ring body 1219 to release the contact between the ring body 1219 and the side of the leg unit 15, and then pulls the connecting rod 1218 through the sliding mouth, and the traction disc body 1213 moves along the rotating column 1214 and separates from the rod body 1212 and no longer fits, and then constrains the length power unit 121 again, thereby achieving that during the change of vertical position, the span of the side of the leg unit 15 close to the indoor wall remains unchanged.

[0058] After the height change is achieved, the motor 124 and the suction member 1282 are powered off and stop operating. The right-angle embedded platform 1283 moves downward due to the elastic force of the spiral beryllium copper wire 1285 and the mass of the body, and bites into the umbrella plate 125 and the umbrella plate 2 126, thereby preventing the screw 17 from rotating, and there is no need for the motor 124 to always serve as a limiting and constraining power.

[0059] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
