[0016] According to the above technical solution, a flexible adjustment component is provided at the bottom of the base section, and the flexible adjustment component includes a mounting bracket;

[0017] The base section is connected to a mounting bracket at the bottom. The mounting block has a mounting screw hole at the center of its bottom. The mounting bracket is connected to a mounting screw at the bottom. The mounting screw passes through the mounting bracket and connects to the mounting screw hole. The mounting bracket has movable slide rods connected to both sides on one side. A movable rack is connected to one side of the mounting bracket between the two movable slide rods. An assembly base is slidably mounted on the outside of the movable slide rods. The movable rack passes through the inside of the assembly base.

The controller is wirelessly connected to an external control handle.

[0019] According to the above technical solution, the top of the assembly base is provided with a communication port, and a drive gear is rotatably installed on the top of the assembly base at the top of the communication port. The drive gear passes through the communication port and meshes with a movable rack. One end of the drive gear's rotating shaft is connected to a crank handle.

[0020] According to the above technical solution, the top ends of the two movable sliding rods are connected to a counterweight frame, and the counterweight frame has several counterweight cavities inside, with counterweight blocks placed inside the several counterweight cavities.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. It is equipped with a floor level component, and has a base section, a standard section and an output section. Utilizing the elasticity of the telescopic spring, in conjunction with pressing the connecting protrusion, the connecting protrusion can be disengaged from and connected to the connecting hole, realizing flexible connection between the base section, standard section and output section. It is convenient and quick to disassemble and assemble, and the number of standard sections can be flexibly adjusted according to the floor height, making it flexible and convenient to use.

[0023] The infrared level is aligned with the lower elevation control point. The level is then rotated, and through the principle of plane mirror reflection, the lower elevation control line is projected into the device. After two consecutive plane mirror reflections, the projection is transmitted to the upper level, where it is output. Based on the floor elevation requirements, the limit slider is moved, and the top lens is fixed by tightening the fixing nut, thus controlling the distance between the two plane mirrors. The lengths of the base section and standard section are fixed, and the output light is projected at the calculated scale line position. Compared to measuring with a tape measure, this device has smaller measurement errors and is more accurate. The projection is transmitted once at each laying hole, and the control points on the upper level are checked for closure using a level to ensure accurate transmission. This eliminates the need for a large amount of labor and time spent on laying out lines, resulting in higher work efficiency. Utilizing existing laying holes for elevation measurement eliminates the need for operations on the outside of the exterior wall, ensuring worker safety.

[0024] The input plastic sheet and output plastic plate are connected to the base section and output section respectively by bolts, facilitating maintenance of the input and output plastic sheets. The fixing screw passes between two flexible magnetic strips. When the limit slider is fixed, the flexible magnetic strips away from the fixing screw attract each other under the action of magnetic force, blocking the lifting port. During the transmission of the elevation control line, this prevents external dust from entering the output section from the lifting port, avoiding dust contamination of the output plastic plate and blocking the light output, thus improving the stability of the device. When the device is not in use, the dustproof plate is pushed into the base section. The fixing of the magnetic sheet and the supporting iron frame can seal the top of the bottom lens, preventing dust or stones from entering the base section and contaminating or damaging the bottom lens, thus improving the stability of the device.

[0025] 2. Equipped with a flexible adjustment component, the controller is wirelessly connected to an external control handle. Driven by the adjustment gear and gear ring, when marking elevation control points, the operator can remotely control the external control handle to control the operation of the adjustment motor. By controlling the rotation of the output section, the orientation of the output plastic plate is controlled, thereby changing the direction of the output light. The direction of the output light can be flexibly adjusted as needed, so that the output light can illuminate the corresponding wall and column according to the on-site wall and column distribution of the floor. It has a wide range of applications and does not require manual adjustment of the entire transmission device, making it more convenient and faster.

[0026] The drive gear can move the sliding rod inside the mounting base, allowing the mounting frame to extend into the stairwell and elevator shaft. This enables the device to perform elevation measurements in stairwells and elevator shafts, expanding its application range. By using the drive gear to move the mounting frame, the base section, standard section, and output section are moved into the stairwell and elevator shaft. Compared to the traditional method of using a measuring tape with a worker's probe to measure elevation, this device eliminates the need for a worker's probe, making it safer.

[0027] In summary, the floor elevation component controls the height of the output light by moving the limit slider and the top lens. Compared to the comparison document, the movement of the top lens is more labor-saving and convenient. Furthermore, the flexible adjustment component allows for flexible control of the direction of the output light using an external control handle. Compared to the comparison document and traditional elevation devices, this device can direct the output light onto the corresponding walls and columns based on the on-site wall and column distribution of the floor, making elevation more convenient and faster.

[0047] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0048] Example: Figure 1-14As shown, the present invention provides a technical solution for a floor elevation control line transmission device, including a base section 1. A floor elevation component 2 is provided on the top of the base section 1. The floor elevation component 2 includes an installation iron block 201, a lens bracket 202, a bottom lens 203, an input plastic sheet 204, an incident ring 205, a shielding plate 206, a pull rod 207, a magnet block 208, a horizontal bubble 209, a connecting hole 210, a standard section 211, a connecting pipe 212, an assembly block 213, a telescopic spring 214, a connecting protrusion 215, a light-transmitting hole 216, an output section 217, an output plastic plate 218, a scale line 219, a lifting port 220, a limit slider 221, a top lens 222, a fixing screw 223, a fixing nut 224, a shielding cloth 225, a flexible magnetic strip 226, a fixing plate 227, a connecting drum 228, a docking seat 229, a dustproof plate 230, a fixing magnetic sheet 231, and a supporting iron frame 232.

[0049] A mounting block 201 is installed on the bottom inner side of the base section 1. A lens bracket 202 is placed on top of the mounting block 201. A bottom lens 203 is adhered to the top surface of the lens bracket 202. An input plastic sheet 204 is bolted to one side of the base section 1, facing the bottom lens 203. An incident circle 205 is drawn in the center of the input plastic sheet 204. A baffle plate 206 is bolted to one side of the base section 1, facing away from the bottom lens 203. A pull rod 207 is welded to one side of the lens bracket 202. A component is fixed to the bottom inner side of the lens bracket 202. The magnet 208, the mounting iron block 201, and the lens holder 202 are all made of iron. The magnet 208 can firmly fix the lens holder 202 to the top of the mounting iron block 201. When the bottom lens 203 needs to be cleaned or replaced, the shield 206 can be removed and the lens holder 202 can be taken out to facilitate the cleaning or replacement of the bottom lens 203. A horizontal bubble 209 is installed on one side of the base section 1 at the bottom of the shield 206. By observing the position of the bubble, it can be determined whether the base section 1 is vertical. Connection holes 210 are opened on the top of all four sides of the base section 1.

[0050] The base section 1 has two standard sections 211 connected to the top, and a connecting pipe 212 connected to the bottom of the standard section 211. An output section 217 is connected to the top of the top standard section 211. An output plastic plate 218 is bolted to one side of the output section 217. The surface of the output plastic plate 218 is provided with scale lines 219. A lifting port 220 is opened on one side of the output section 217 opposite to the output plastic plate 218. A limit slider 221 is slidably installed inside the output section 217. A top lens 222 is glued to the bottom surface of the limit slider 221. The outer side of the limit slider 221 fits against the inner side of the output section 217, so that the limit slider 221 can move stably inside the output section 217. Both the outer side of the limit slider 221 and the inner side of the output section 217 are smooth surfaces, which reduces the frictional resistance between the limit slider 221 and the output section 217. The input plastic sheet 204 and the output plastic plate 218 are both transparent plastic sheets.

[0051] Both the lens holder 202 and the limiting slider 221 have isosceles triangles in their longitudinal sections. The angle between the bottom lens 203 and the horizontal plane is 45 degrees, and the angle between the top lens 222 and the horizontal plane is also 45 degrees. The bottom lens 203 and the top lens 222 are plane mirrors. When the laser of the infrared level shines on the surface of the bottom lens 203 from the incident ring 205, the incident angle is equal to the reflection angle. Under the effect of mirror reflection, the laser reflected by the bottom lens 203 shines on the surface of the top lens 222. After being reflected by the top lens 222, the laser is horizontally reflected out from the output plastic plate 218.

[0052] A fixing screw 223 is welded to one side of the limiting slider 221 at the position corresponding to the lifting port 220. The top of the fixing screw 223 passes through the lifting port 220. On one side of the output section 217, there are shielding cloths 225 fixed to both sides of the lifting port 220 by fixing plates 227. Flexible magnetic strips 226 are connected to the adjacent sides of the two shielding cloths 225. A fixing nut 224 is connected to the outside of the fixing screw 223 through a threaded hole. Tightening the fixing nut 224 will make it fit tightly with the fixing plate 227. Under the action of friction, the limiting slider 221 can be stably fixed inside the output section 217. The fixing screw 223 passes through the middle of the two flexible magnetic strips 226. When the limiting slider 221 moves, the fixing screw 223 moves the surrounding shielding cloths 225. When the limiting slider 221 is fixed, under the action of magnetic force, the flexible magnetic strips 226 away from the fixing screw 223 attract each other and block the lifting port 220, preventing external dust from entering the output section 217 from the lifting port 220.

[0053] The bottom of the output section 217 is connected to a connecting drum 228. A docking seat 229 is rotatably connected to the outside of the connecting drum 228. The docking seat 229 is embedded in the top of the inner side of the adjacent standard section 211. Assembly blocks 213 are installed on the bottom of the inner side of the connecting pipe 212 and the docking seat 229. The top of the four sides of the assembly block 213 is connected to a connecting protrusion 215 by a telescopic spring 214. The top of the connecting protrusion 215 penetrates the adjacent surface of the adjacent connecting pipe 212. A light-transmitting hole 216 is opened through the center of the assembly block 213. The laser reflected by the bottom lens 203 can pass through the light-transmitting hole 216 and the connecting drum 228 to irradiate the surface of the top lens 222.

[0054] The standard section 211 also has connection holes 210 on all four sides. The connecting pipe 212 at the bottom of the bottom standard section 211 is embedded in the top inner side of the base section 1. The connecting pipe 212 at the bottom of the top standard section 211 is embedded in the top inner side of the bottom standard section 211. The connecting protrusion 215 is embedded in the corresponding connecting hole 210. By using the telescopic property of the telescopic spring 214, the connecting protrusion 215 can be pressed, and the connecting protrusion 215 can flexibly disengage from and connect with the connecting hole 210, thereby realizing the flexible connection between the base section 1, the standard section 211 and the output section 217.

[0055] A dustproof plate 230 is slidably installed on one side of the base section 1 at the top of the bottom lens 203. A fixed magnetic sheet 231 is connected to one end of the dustproof plate 230. A supporting iron frame 232 is connected to the bottom of the dustproof plate 230 on one side of the base section 1. When the device is not in use, the dustproof plate 230 is pushed into the base section 1. The fixed magnetic sheet 231 and the supporting iron frame 232 can seal the top of the bottom lens 203 to prevent dust or stones from entering the base section 1 and contaminating or damaging the bottom lens 203.

[0056] The bottom of the base section 1 is provided with a flexible adjustment component 3, which includes a mounting bracket 301, mounting screw holes 302, mounting screws 303, a movable slide bar 304, a movable rack 305, a mounting base 306, a connecting port 307, a drive gear 308, a crank handle 309, a mounting screw hole 310, a counterweight frame 311, a counterweight cavity 312, a counterweight block 313, a tripod 314, a mounting plate 315, a gear ring 316, a support hole 317, a rubber sealing plug 318, a support frame 319, an adjustment motor 320, and an adjustment gear 321.

[0057] The base section 1 is connected to a mounting bracket 301 at the bottom. The mounting block 201 has a mounting screw hole 302 at the center of its bottom. The mounting bracket 301 is connected to a mounting screw 303 at the bottom. The mounting screw 303 passes through the mounting bracket 301 and connects to the mounting screw hole 302. The mounting bracket 301 is connected to two movable slide rods 304 on one side. The mounting bracket 301 is connected to a movable rack 305 between the two movable slide rods 304 on one side. The movable slide rods 304 are slidably mounted to an assembly seat 306 on the outside. The movable rack 305 passes through the interior of the assembly seat 306. The assembly seat 306 has an assembly screw hole 310 at the center of its bottom. The bottom of the assembly seat 306 is connected to the top of the tripod 314 through the assembly screw hole 310. By adjusting the tripod 314 and observing the position of the bubble inside the horizontal bubble 209, it can be determined whether the base section 1, standard section 211, and output section 217 are perpendicular to the horizontal plane.

[0058] The top of the mounting base 306 has a connecting port 307. A drive gear 308 is rotatably mounted on the top of the connecting port 307. The drive gear 308 passes through the connecting port 307 and meshes with the movable rack 305. One end of the rotating shaft of the drive gear 308 is connected to a crank 309. When the crank 309 is held and the drive gear 308 is rotated, the drive gear 308 can drive the movable slide bar 304 to move inside the mounting base 306.

[0059] The output section 217 has mounting plates 315 welded to all four sides of its bottom. A gear ring 316 is connected to the outside of the output section 217 via the mounting plates 315. The standard section 211 has support holes 317 at the bottom of the connecting holes 210 on both sides. The top of the standard section 211, which is connected to the output section 217, is connected to a support frame 319 via the support holes 317 and bolts. Rubber sealing plugs 318 are embedded inside the remaining support holes 317 to seal the remaining support holes 317 and prevent dust from entering the standard section 211 through the support holes 317. The top of the support frame 319 is equipped with an adjustment motor 320. The output end of the adjustment motor 320 is connected to an adjustment gear 321, which meshes with a gear ring 316. The input end of the adjustment motor 320 is electrically connected to the output end of the energy storage power supply through a controller. The controller is wirelessly connected to an external control handle. By controlling the external control handle, the operation of the adjustment motor 320 can be controlled. Under the drive of the adjustment gear 321 and the gear ring 316, the output section 217 can be rotated, thereby controlling the orientation of the output plastic plate 218.

[0060] The top ends of the two movable slide rods 304 are connected to a counterweight frame 311. The counterweight frame 311 has several counterweight cavities 312 inside, and counterweight blocks 313 are placed inside the several counterweight cavities 312. The counterweight blocks 313 can balance the overall device, making the overall device more stable when in use.

[0061] The working principle and usage process of this invention are as follows: During installation, the tripod 314 is set at the location of the line-laying hole inside the building. The elevation control point of the lower floor is transferred to the wall column near the line-laying hole using a level. The mounting base 306 is connected to the top of the tripod 314 through the mounting screw hole 310. The mounting screw 303 is used to pass through the mounting bracket 301 and connect to the mounting block 201 through the mounting screw hole 302 to fix the base section 1. The tripod 314 is adjusted to be perpendicular to the horizontal plane by observing the position of the bubble inside the horizontal bubble 209.

[0062] After adjustment, calculate the required number of standard sections 211 based on the floor height. Press the connecting protrusion 215 on the connecting pipe 212 to compress the telescopic spring 214, connecting the bottom of the connecting pipe 212 of the standard section 211 to the top of the adjacent standard section 211. When the connecting protrusion 215 moves to the position of the connecting hole 210, the connection of all standard sections 211 is completed. After the standard sections 211 are connected, press the connecting protrusion 215 on the docking seat 229 to connect the docking seat 229 to the topmost standard section. 211 top connection completes the connection to output section 217. Next, use bolts to connect assembly plate 315 and gear ring 316. Then, remove the rubber sealing plug 318 inside the support hole 317 on the top standard section 211. Use bolts to fix support frame 319 to complete the installation of adjustment motor 320. Next, press the connecting protrusion 215 at the connecting pipe 212 at the bottom of the bottom standard section 211 to connect standard section 211 to the top of base section 1, completing the installation of the overall device.

[0063] Then, align the infrared level with the elevation control point of the lower floor, rotate the infrared level, and adjust the vertical height of the tripod so that the laser emitted by the infrared level enters the incident ring 205 in the middle of the input plastic plate 204. At this time, the laser of the infrared level shines from the incident ring 205 onto the surface of the bottom lens 203, and the incident angle is equal to the reflection angle. Under the effect of specular reflection, the laser reflected by the bottom lens 203 shines onto the surface of the top lens 222. After being reflected by the top lens 222, the laser is horizontally reflected out from the output plastic plate 218. Calculate the output height according to the floor height, loosen the fixing nut 224, move the limit slider 221 and the top lens 222 so that the output light is emitted at the calculated scale line 219. Then tighten the fixing nut 224. 24. Using the friction between the fixing nut 224 and the fixing plate 227, the top lens 222 is fixed. After the output elevation light is emitted, the elevation control point is drawn on the wall column at the corresponding position, completing the transmission of the elevation control line. It is convenient and fast. The length of the foundation section 1 and the standard section 211 is 1 meter, and the length is fixed. With the output light, it is emitted at the calculated scale line 219 position. Compared with measuring with a tape measure, the measurement error of this device is smaller and the measurement is more accurate. It is transmitted once at each laying hole. The control points at each upper layer are checked and closed with a level to ensure accurate transmission. It does not require a lot of laying labor and laying time, and the work efficiency is higher. The elevation is carried out using the existing laying holes, and there is no need to operate on the outside of the outer wall, which ensures the safety of the workers.

[0064] The input plastic sheet 204 and the output plastic plate 218 are connected to the base section 1 and the output section 217 respectively by bolts, which facilitates the maintenance of the input plastic sheet 204 and the output plastic plate 218. The fixing screw 223 passes through the middle of the two flexible magnetic strips 226. When the limit slider 221 moves, the fixing screw 223 moves the surrounding shielding cloth 225. When the limit slider 221 is fixed, under the action of magnetic force, the flexible magnetic strips 226 away from the fixing screw 223 attract each other and block the lifting port 220. During the transmission of the elevation control line, it prevents external dust from entering the interior of the output section 217 from the lifting port 220, and avoids the output plastic plate 218 from being blocked by dust, so as to ensure the stable use of the entire transmission device.

[0065] The controller is wirelessly connected to an external control handle. Driven by the adjustment gear 321 and gear ring 316, when drawing elevation control points, the staff can remotely control the external control handle to control the operation of the adjustment motor 320. By controlling the rotation of the output section 217, the orientation of the output plastic plate 218 is controlled, thereby changing the direction of the output light. The direction of the output light can be flexibly adjusted as needed so that the output light can illuminate the wall column at the desired elevation. There is no need to manually rotate the entire transmission device for adjustment, which is more convenient and faster.

[0066] When the device is not in use, push the dustproof plate 230 into the base section 1. The fixing of the fixed magnetic plate 231 and the supporting iron frame 232 can seal the top of the bottom lens 203, preventing dust or stones from entering the base section 1 and contaminating or damaging the bottom lens 203, thus making the device more stable in use.

[0067] When the device needs to be used to elevate floors in stairwells and elevator shafts, place tripod 314 next to the stairwell and elevator shaft. Rotate drive gear 308 by hand using crank 309. Drive gear 308 meshes with moving rack 305, causing moving slide bar 304 to move inside mounting base 306, allowing mounting bracket 301 to extend into the stairwell and elevator shaft. After adjusting the device and installing base section 1, standard section 211, and output section 217, repeat the standard control line transmission method above to enable the device to... This device is used for elevation measurement in stairwells and elevator shafts, making it more widely applicable. The drive gear 308 moves the mounting frame 301 to move the base section 1, standard section 211, and output section 217 into the stairwell and elevator shaft. Compared to the traditional method of using a measuring tape with a worker's probe to measure elevation, this device eliminates the need for a worker's probe, making it safer. The tops of the two moving slide rods 304 are connected to a counterweight frame 311, and a counterweight block 313 is placed inside the counterweight cavity 312. The counterweight block 313 can balance the entire device, making the entire device more stable during use.
