Description

Technical Field

[0001] This invention relates to the field of interior decoration measurement equipment technology, specifically to a multi-functional measurement device for interior decoration design. Background Technology

[0002] With the standardization and refinement of the interior decoration industry, on-site measurement, surveying, and construction positioning have become crucial preliminary steps in decoration design and on-site construction. This requires precise dimensional measurements of door and window openings, beam and column structures, water and electricity points, and pipe elevations. Simultaneously, it necessitates using baselines and markings to complete wall leveling, tile laying, ceiling installation, and cabinet installation. Currently, the industry primarily uses single-function measuring tools, requiring the separate carrying of rangefinders, line projectors, and leveling devices. These tools are scattered, cumbersome to carry, and the workflow is cumbersome, significantly reducing the efficiency of on-site measurement and construction positioning, and failing to meet the demands of modern interior decoration for rapid surveying and integrated operations.

[0003] While existing integrated decoration measurement equipment combines basic measurement and line projection functions, it still suffers from numerous technical defects: the equipment display screen is mostly a fixed installation structure, which cannot adjust the height and angle. In situations where the ceiling is high, the ground is low, or the measurement is done from above or below, the viewing angle is limited and the readings are inconvenient; the core laser ranging component lacks an effective shock absorption structure. On-site personnel walking or slight bumps to the equipment can easily cause the component to shake, resulting in laser line drift, jumps in ranging data, and difficulty in ensuring measurement accuracy. This seriously affects the accuracy of decoration dimension surveying and construction positioning.

[0004] Meanwhile, traditional measuring equipment has a relatively simple heat dissipation and dust prevention design. When the equipment is working continuously for a long time, internal components are prone to heat accumulation and aging, which affects the service life and working stability. When the equipment is idle and stopped, the heat dissipation holes have no sealed protective structure, and external dust and impurities can easily enter the machine body, causing dust accumulation and jamming of precision sensing and laser components, frequent failures, increasing the later maintenance costs, and making it difficult to meet the requirements of long-term stable use in complex indoor decoration environments. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multifunctional measuring device for interior decoration design, which solves the technical problems of existing decoration measuring tools, such as fragmented functions, limited observation angles, easy laser drift caused by construction vibration, skipped distance readings, poor measurement accuracy, heat accumulation during long-term operation, easy dust accumulation during shutdown, short service life, and poor on-site adaptability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional measuring device for interior decoration design, comprising a housing, a display screen on one side of the top of the housing, a main control board fixedly installed inside the housing, and three isolation chambers within the housing via three partition plates. Each of the three isolation chambers houses a laser ranging component, an angle and attitude sensing component, and a laser line projection component, respectively. Cylinders are fixedly installed on both sides of the bottom of the housing. Cylindrical blocks are fixedly installed on both sides of the inside of each cylinder, and the inside of the cylinder is divided into a central inner cavity and two outer cavities by the two cylindrical blocks. Both the inner and outer cavities are filled with hydraulic oil. Several flow grooves are formed inside each cylindrical block. Several conical fluid dividers are fixedly installed inside each flow groove. Hook-shaped fluid-blocking devices are fixedly installed on both sides of each conical fluid divider inside the flow groove. Rubber baffles are installed on both sides of each flow groove.

[0007] Preferably, a control button is fixedly installed on the other side of the top of the housing.

[0008] Preferably, a battery compartment is provided at the bottom center of the outer casing.

[0009] Preferably, the bottom four corners of the laser ranging component are all connected to the inside of the housing by buffer springs.

[0010] Preferably, each of the outer cavities has a push-pull rod movably installed inside, a piston is fixedly installed on the inner end of each push-pull rod, the outer end of each push-pull rod extends to the outside of the cylinder and is movably installed with a connecting rod, and the end of each connecting rod is movably installed at the bottom of the laser ranging component.

[0011] Preferably, an arc-shaped spring tube is fixedly installed at the inner bottom of the outer shell, and a central shaft is movably installed inside the outer shell near the center of the arc-shaped spring tube. A transmission gear is fixedly installed on the outer diameter of the central shaft, and a lever frame is movably installed inside the outer shell near the central shaft via a movable shaft. A sector gear is fixedly installed on the inner end of the lever frame, and the sector gear meshes with the inner end of the transmission gear.

[0012] Preferably, a rocker arm is movably mounted at one end of the arc-shaped spring tube, and the end of the rocker arm is movably mounted at the outer end of the lever frame. Several straight rods are uniformly fixedly mounted at the bottom end of the central shaft, and several hole-blocking plates are fixedly mounted at the bottom end of each straight rod. Heat dissipation holes are provided at the bottom end of the outer shell near the hole-blocking plates.

[0013] Preferably, an outer cylinder is fixedly installed at the top of the outer casing near the display screen, a middle cylinder is movably installed inside the outer cylinder, an inner cylinder is movably installed inside the middle cylinder, a ball seat is fixedly installed at the top of the inner cylinder, and the top of the ball seat is fixedly installed at the bottom center of the display screen. The inner walls of the outer cylinder, middle cylinder, and inner cylinder are all connected by a number of limiting protrusions with interference fit.

[0014] This invention provides a multifunctional measuring device for interior decoration design. It has the following beneficial effects: 1. This invention solves the problems of laser drift, ranging jumps, and data fluctuations caused by shaking and collisions in traditional measuring equipment by setting a suspension and shock absorption structure with buffer springs and hydraulic damping for the core measuring component, laser ranging assembly. This ensures continuous measurement accuracy and is suitable for complex construction site environments.

[0015] 2. This invention innovatively features a temperature-adaptive heat dissipation and dust prevention structure, solving the dual problems of heat accumulation during long-term operation and dust accumulation during shutdown in traditional measuring equipment. When the equipment stops, the internal temperature drops to normal, and the arc-shaped spring tube automatically resets, causing the shielding plate to re-seal the heat dissipation holes. This effectively prevents external dust, debris, and moisture from entering the equipment through the heat dissipation holes, avoiding dust accumulation, contamination, and damage to internal precision components. This significantly reduces the probability of equipment failure and subsequent maintenance costs, effectively extending the overall service life of the equipment.

[0016] 3. The invention employs a nested lifting structure consisting of an outer cylinder, a middle cylinder, and an inner cylinder, combined with a ball seat to enable flexible adjustment of the display screen at multiple angles and heights, thus solving the drawbacks of fixed display screens and limited viewing angles in traditional measuring equipment. Through the interference fit of the multi-stage cylinders, the height of the display screen can be freely raised and lowered and stably positioned. Simultaneously, relying on the ball seat structure, the display screen can be flipped up and down and rotated left and right, avoiding problems such as obstructed view, glare, and unclear observation that occur when measuring from above, below, or at different heights.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a multi-functional measuring device for interior decoration design, such as... Figure 1 As shown, the device includes an outer shell 1, which serves as the overall load-bearing base of the equipment. It provides a stable mounting carrier and protective shell for all electrical components, sensing components, shock absorption structures, heat dissipation and transmission structures, and top display structures inside the equipment. It can isolate the internal precision components from dust, minor bumps, and external pressure at the construction site, while also organizing the installation positions of each component to ensure that each structure works independently and in a coordinated manner.

[0021] A display screen 2 is installed on the top side of the outer casing 1. The display screen 2 is the visual display terminal of the device, which can display various measurement parameters such as laser ranging data, spatial tilt data, and azimuth angle data in real time. With the subsequent adjustable support structure, it can adapt to the viewing needs of different measurement conditions, making it convenient for operators to intuitively read various construction parameters of decoration measurement.

[0022] The main control board 5 is fixedly installed inside the outer casing 1. The main control board 5 is the core control center of the equipment. It is electrically connected to all functional components of the equipment and can uniformly receive the acquisition signals from the laser ranging component 7 and the angle and attitude sensing component 8, complete data calculation, error correction and data analysis, and control the start and stop of the laser line projection component 9, so as to realize the integrated intelligent control of equipment measurement, line projection and data calibration.

[0023] The interior of the outer shell 1 is also equipped with three isolation chambers through three isolation plates 6. The isolation plates 6 adopt a split isolation design, dividing the interior of the outer shell 1 into three independent installation cavities, effectively isolating the electromagnetic interference and structural vibration interference generated during the operation of each working component, ensuring that each functional module operates independently and stably, and avoiding data disorder and functional failure when multiple components are integrated.

[0024] The three isolation chambers are respectively equipped with a laser ranging component 7, an angle and attitude sensing component 8, and a laser line projection component 9. By installing them in separate isolation chambers, the three core measurement functions of decoration—range measurement, attitude detection, and laser line projection—are integrated into one unit. The laser ranging component 7 is responsible for measuring various dimensions, elevations, and spacing data; the angle and attitude sensing component 8 is responsible for correcting equipment attitude errors; and the laser line projection component 9 is responsible for providing construction benchmark lines, comprehensively covering construction scenarios such as measuring, positioning, leveling, and tiling in interior decoration.

[0025] Cylinders 11 are fixedly installed on both sides of the bottom of the outer shell 1. The cylinders 11 are the core mounting base of the hydraulic shock absorption structure of the equipment. They are fixed at symmetrical positions at the bottom of the outer shell 1 to ensure that the shock absorption structure is subjected to balanced force. They provide a closed and stable installation space for the subsequent hydraulic buffer and damping reset structure. They are the key external structure for realizing the shock absorption protection of the laser ranging component 7.

[0026] Cylindrical blocks 12 are fixedly installed on both sides of the cylinder body 11, and the inside of the cylinder body 11 is divided into an inner cavity 13 in the middle and outer cavities 14 on both sides by the two cylindrical blocks 12. The cylindrical blocks 12 are cavity dividing components. By symmetrically fixing them, the inside of the cylinder body 11 is precisely divided into independent inner cavities 13 and outer cavities 14, forming a bidirectional hydraulic flow cavity structure, which provides a structural basis for the differentiated flow of hydraulic oil 15 and the realization of unidirectional damping and shock absorption effect.

[0027] Both the inner cavity 13 and the outer cavity 14 are filled with hydraulic oil 15. The hydraulic oil 15 serves as a shock-absorbing transmission medium and can circulate between the inner cavity 13 and the outer cavity 14. Through its smooth forward flow and reverse damping and flow-limiting characteristics, it works in conjunction with various flow-blocking components to achieve buffering and shock absorption functions, thereby offsetting the interference of equipment vibration on the measurement of the laser ranging component 7.

[0028] The cylindrical stop 12 has several flow grooves 16 inside. The flow grooves 16 are dedicated channels for the bidirectional flow of hydraulic oil 15 between the inner cavity 13 and the outer cavity 14. They are evenly distributed inside the cylindrical stop 12 to ensure that the hydraulic oil 15 flows evenly and is under stable force, and to ensure that the overall shock absorption structure works smoothly without local jamming or stagnation.

[0029] Several conical flow dividers 17 are fixedly installed inside the flow channel 16. The conical flow dividers 17 are hydraulic damping flow dividers. They mainly function to divide each flow of hydraulic oil 15 back into two evenly during the reverse flow process, change the original flow trajectory of the fluid, initially lose fluid kinetic energy, increase reverse flow resistance, and provide a basic guarantee for the shock absorption and damping effect.

[0030] Inside the flow channel 16, hook-shaped flow blocking fluids 18 are fixedly installed on both sides near each conical flow divider 17. The hook-shaped flow blocking fluids 18 work together with the conical flow dividers 17 to further change the direction of fluid movement after the hydraulic oil 15 is reversed, causing multiple fluids to collide and turbulently flow together, greatly reducing the return kinetic energy of the hydraulic oil 15, significantly improving the reverse flow damping, and effectively reducing the reset sway speed of the ranging component.

[0031] Rubber baffles 19 are installed on both sides of the flow channel 16. The rubber baffles 19 are unidirectional flow-guiding sealing components with elastic opening and closing characteristics. They can automatically open and close according to the pressure difference between the inner cavity 13 and the outer cavity 14, adapting to the forward and reverse flow requirements of the hydraulic oil 15, ensuring smooth forward buffering and pressure relief, and stable reverse damping and flow limiting, thus achieving differentiated shock absorption function.

[0032] In this embodiment, a control button 3 is fixedly installed on the other side of the top of the outer shell 1. The control button 3 is the human-machine interaction operation component of the device and is electrically connected to the main control board 5. Operators can use the control button 3 to complete operations such as powering on the device, switching functions, setting parameters, and starting and stopping components. The operation is simple and convenient, and it meets the needs of rapid operation on the construction site.

[0033] Furthermore, a battery compartment 4 is provided at the bottom center of the outer casing 1. The battery compartment 4 is the mounting cavity for the power supply components of the device, which is used to house the power supply battery to provide continuous power to the display screen 2, the main control board 5 and various measurement and sensing components. At the same time, the built-in mounting structure can protect the power supply battery from impact damage and ensure normal use of the device in outdoor and field scenarios where there is no external power supply.

[0034] Furthermore, the bottom four corners of the laser ranging component 7 are all connected to the inside of the outer shell 1 by buffer springs 10. The buffer springs 10 evenly distributed at the four corners form a suspension support structure, which provides flexible suspension support for the laser ranging component 7. When the equipment is subjected to shaking or collision vibration, it can initially buffer the downward impact force, weaken the transmission of rigid vibration, and provide a pre-buffering effect for subsequent hydraulic damping shock absorption.

[0035] Furthermore, push-pull rods 20 are movably installed inside the outer cavity 14. The push-pull rods 20 are vibration transmission components that can perform horizontal reciprocating extension and retraction movements inside the outer cavity 14 to accurately transmit the swaying displacement of the laser ranging component 7, realize the linkage transmission between the mechanical structure and the hydraulic structure, and ensure that the shock absorption structure responds synchronously to the vibration state of the equipment.

[0036] Pistons 21 are fixedly installed on the inner end of the push-pull rod 20. The pistons 21 fit precisely with the inner wall of the outer cavity 14 and can move synchronously with the push-pull rod 20. The displacement of the pistons 21 changes the internal volume and pressure of the outer cavity 14, providing pressure power for the flow of hydraulic oil 15. It is the core transmission component for realizing hydraulic damping operation.

[0037] The outer ends of the push-pull rods 20 extend to the outside of the cylinder body 11 and are movably mounted with connecting rods 22. The connecting rods 22 serve as intermediate transmission connectors, which can flexibly adapt to angle deflection, eliminate mechanical jamming during displacement transmission, and stably convert the vertical swaying displacement of the laser ranging component 7 into the horizontal extension and retraction displacement of the push-pull rods 20, ensuring accurate and smooth transmission.

[0038] The ends of the connecting rods 22 are all movably mounted on the bottom of the laser ranging component 7. Through the bottom hinged mounting method, they can follow the up and down swaying motion of the laser ranging component 7 in real time, accurately transmit vibration displacement, and ensure that the shock absorption structure can respond to every tiny vibration in real time, thus ensuring measurement stability in all aspects.

[0039] Furthermore, an arc-shaped spring tube 23 is fixedly installed at the inner bottom of the outer casing 1. The arc-shaped spring tube 23 is a temperature-sensing deformation component with thermal expansion and contraction deformation characteristics. When the internal temperature of the equipment rises, it will produce elastic deformation with a straightening tendency. When the temperature drops, it can automatically reset, providing a power source for the adaptive heat dissipation structure.

[0040] Inside the outer casing 1, near the center of the arc-shaped spring tube 23, a central shaft 24 is movably installed. The central shaft 24 is the rotating main shaft of the heat dissipation shielding structure, which can rotate flexibly to support the straight rod 29 and the shading plate 30, drive the shielding structure to rotate as a whole, and realize the opening and closing of the heat dissipation hole 31.

[0041] A transmission gear 25 is fixedly installed on the outer diameter of the central shaft 24. The transmission gear 25 is the core component of the gear transmission. It rotates synchronously with the central shaft 24 and transmits power through gear meshing to realize the linkage between temperature deformation action and heat dissipation opening and closing action.

[0042] Inside the outer casing 1, on the side near the central shaft 24, a lever frame 26 is movably mounted via a movable shaft. The lever frame 26 is a lever transmission component that can rotate around the movable shaft, amplifying and converting the minute deformation displacement of the arc-shaped spring tube 23 into rotational motion, thereby improving transmission sensitivity and ensuring timely response of the heat dissipation structure.

[0043] A sector gear 27 is fixedly installed on the inner end of the lever frame 26, and the sector gear 27 is meshed with the inner end of the transmission gear 25. The sector gear 27 and the transmission gear 25 mesh precisely, so as to stably transmit the rotational power of the lever frame 26 to the central shaft 24, realize the mechanical transmission without jamming and with high precision, and ensure the precise opening and closing of the heat dissipation structure.

[0044] Furthermore, a rocker arm 28 is movably mounted on one end of the arc-shaped spring tube 23, and the end of the rocker arm 28 is movably mounted on the outer end of the lever frame 26. The rocker arm 28 is a displacement transmission component, which can accurately transmit the deformation displacement of the arc-shaped spring tube 23 to the lever frame 26, thereby driving the lever frame 26 to complete the rotation action and realizing the linkage between temperature and mechanical transmission.

[0045] Several straight rods 29 are evenly fixedly installed at the bottom of the central shaft 24. The multiple sets of straight rods 29 are evenly arranged as extension support components, synchronously transmitting the rotational power of the central shaft 24, and ensuring that the multiple sets of hole-blocking plates 30 at the bottom rotate synchronously and in the same direction.

[0046] Several hole-blocking plates 30 are fixedly installed at the bottom of the straight rod 29. The hole-blocking plates 30 are sealing components for blocking the heat dissipation holes 31. They rotate with the straight rod 29 to switch positions, realizing two working states: opening for heat dissipation and closing for dust prevention.

[0047] Heat dissipation holes 31 are provided at the bottom of the outer casing 1 near the perforated plate 30. The heat dissipation holes 31 are channels for the heat to be discharged from the inside of the equipment. The heat dissipation holes are opened when the equipment is heated up and closed to prevent dust when the equipment is stopped, so as to realize the adaptive heat dissipation and dust prevention function.

[0048] Furthermore, an outer cylinder 32 is fixedly installed on the top of the outer shell 1 near the display screen 2. The outer cylinder 32 is the outermost fixed base of the multi-stage telescopic adjustment structure. It is fixed to the top of the outer shell 1 and provides a limiting and supporting basis for the telescopic movement of the middle cylinder 33 and the inner cylinder 34.

[0049] The outer cylinder 32 has a movable middle cylinder 33 installed inside. The middle cylinder 33 is an intermediate telescopic adjustment component that can slide vertically inside the outer cylinder 32 to realize two-level height adjustment of the display screen 2, adapting to the usage needs of different measurement heights.

[0050] An inner cylinder 34 is movably installed inside the middle cylinder 33. The inner cylinder 34 is an inner telescopic adjustment component that can flexibly extend and retract inside the middle cylinder 33. Together with the outer cylinder 32 and the middle cylinder 33, it forms a three-stage telescopic structure, which greatly improves the height adjustment range of the display screen 2.

[0051] The top of the inner cylinder 34 is fixedly installed with a ball seat 35, and the top of the ball seat 35 is fixedly installed at the bottom center of the display screen 2. The ball seat 35 is a universal adjustment component. Relying on the spherical rotation characteristics, the display screen 2 can be adjusted to multiple angles such as flipping up and down and rotating left and right, adapting to different observation angles such as looking up at the ceiling, looking down at the ground, and looking straight at the wall.

[0052] The inner walls of the outer cylinder 32, the middle cylinder 33 and the inner cylinder 34 are all connected by several limiting protrusions 36 through interference fit. The limiting protrusions 36, through interference fit, allow the multi-stage cylinder to be stably limited to any position after the extension and retraction adjustment, preventing the display screen 2 from slipping or shaking on its own, and ensuring the stability of use after adjustment.

[0053] Working principle: Powering on via control button 3, the laser ranging component 7 measures the width, height, and depth of door and window openings; the cross-sectional dimensions, location (distance from the wall), and bottom elevation of beams and columns; the height of switches and sockets from the ground and distance from the wall; and the location and elevation of water pipes and heating pipes. The laser projection component 9 projects horizontal, vertical, and cross lines, providing visual references for wall leveling, floor sloping, ceiling installation, tile laying, and cabinet positioning. The angle and attitude sensing component 8 detects the equipment's horizontal and vertical tilt angles in real time, collects spatial orientation and rotation data, and corrects measurement attitude errors. Pulling the display screen 2 outwards allows the outer cylinder 32, middle cylinder 33, and inner cylinder 34 to raise it. The limiting protrusion 36 provides an interference fit for limiting the height, and the ball seat 35 allows the display screen 2 to be flipped up and down and rotated left and right. Measurements can be taken from any position—high or low, looking up at the ceiling or down at the ground—ensuring a direct view and avoiding limited viewing angles during high / low or high / low measurements. The laser ranging component 7 has a suspended shock-absorbing component inside. When the user walks or bumps into something, the laser ranging component 7 will shake. When it shakes and descends, the buffer spring 10 increases the downward resistance. At this time, the connecting rod 2... 2. The push-pull rod 20 moves inward, causing the piston 21 to follow. The pressure inside the outer cavity 14 increases, opening the rubber baffle 19. Hydraulic oil 15 in the outer cavity 14 enters the inner cavity 13 through the flow groove 16. During this inward flow, the hydraulic oil 15 is almost unaffected by the outer ends of the conical fluid divider 17 and the hook-shaped fluid blocker 18, resulting in relatively smooth flow. When the piston rises to its restoring position, the connecting rod 22 moves the push-pull rod 20 and piston 21 outward. At this time, the pressure inside the outer cavity 14 decreases, and the rubber baffle 19 opens again, allowing the hydraulic oil 15 in the inner cavity 13 to flow outward through the flow groove 16. The hydraulic oil 15 flowing into the outer cavity 14 flows in reverse through the channel 16. During the reverse flow, each hydraulic oil 15 entering the channel 16 is divided in two by the conical fluid divider 17. Then, during the flow, the direction of movement is changed and collision occurs by the hook-shaped fluid blocking 18 on both sides, resulting in loss of kinetic energy. Through the action of multiple sets of conical fluid dividers 17 and hook-shaped fluid blocking 18, the resistance of the hydraulic oil 15 during the return flow is greatly increased, thereby greatly reducing the reset speed of the push-pull rod 20 and the connecting rod 22, achieving the vibration reduction effect of the laser ranging component 7, and avoiding laser drift and ranging jumps during measurement.

[0054] After prolonged use, the equipment will generate internal heat. This heat acts on the wall of the arc-shaped spring tube 23, causing it to undergo elastic deformation with a tendency to straighten. This displacement at the tail of the tube leads to the rotation of the lever frame 26 via the swing rod 28. The rotation of the lever frame 26 causes the sector gear 27 to rotate as well. The rotating sector gear 27 meshes with the transmission gear 25, causing the central shaft 24 to rotate. The central shaft 24 then causes all the straight rods 29 to rotate, thereby moving all the hole-blocking plates 30 and releasing their blocking effect on the heat dissipation holes 31. This allows heat to escape from the heat dissipation holes 31, achieving real-time heat dissipation. When the equipment is stopped, the internal temperature returns to normal, the arc-shaped spring tube 23 resets, and all the hole-blocking plates 30 re-block the heat dissipation holes 31, preventing external dust and dirt from entering the equipment when it is not in use.
