Description

Technical Field

[0001] This invention relates to the field of on-site testing technology, and more specifically, to a handheld tilt angle detection and marking tool, which is mainly used for the later detection of component tilt angle and verticality, point marking, and multiple retesting and verification operations at construction sites of buildings and bridges. Background Technology

[0002] During the construction of buildings, bridges, steel structures, and other engineering projects, it is necessary to measure and monitor the installation tilt angle and spatial posture of various components to ensure that the installation accuracy of the components meets the design requirements. Currently, the commonly used tilt measurement tools on engineering sites are mainly digital tiltmeters and total stations.

[0003] Existing handheld digital inclinometers include single-axis and dual-axis types, typically employing a square box structure. They measure by fitting the bottom plane against the component being measured, and feature real-time angle display and reading hold locking functions. However, their locking buttons are mostly located on the side of the device, with the pressing direction parallel to the instrument's contact surface. Lateral pressing can easily cause slight slippage or deflection of the instrument, resulting in distorted locking angles. This usually requires two-handed operation. Furthermore, existing inclinometers only have angle measurement functions and lack an integrated physical marking structure. The location of the measuring point can only be roughly delineated manually by the operator afterward, resulting in low marking accuracy. During remeasurement, it is difficult to accurately locate the same measuring point, making multiple accurate verifications of the same location impossible, and leading to insufficient continuity and traceability of measurement data.

[0004] Total stations can indirectly calculate the tilt angle of components by measuring the three-dimensional coordinates of measuring points and converting them. They offer high overall measurement accuracy and can achieve multi-point synchronous monitoring, making them suitable for overall alignment control of large components. However, total stations are large and heavy, and the on-site setup process is complex, requiring leveling, centering, and setting backsight points, resulting in lengthy preparation time. The measurement process is heavily dependent on line-of-sight conditions and is significantly limited by construction obstructions, ambient light, and work site conditions, making it impossible to quickly inspect components in narrow or concealed locations. Total stations only output coordinate data and cannot directly display tilt angle values, requiring manual conversion later, resulting in poor on-site reading intuitiveness. Furthermore, total stations lack direct physical point marking capabilities, and re-measurement relies on coordinate positioning, inevitably leading to point deviations. Their portability and on-site rapid detection capabilities are insufficient, making it difficult to meet the needs of multi-point, high-frequency, rapid tilt angle detection and long-term verification monitoring on construction sites.

[0005] In summary, none of the existing tilt measurement tools integrate the physical marking function of the measuring points, resulting in low positioning accuracy of the measuring points, difficulty in re-measurement and alignment, and difficulty in long-term continuous tracking and comparison of measurement data. They cannot meet the needs of efficient, accurate, traceable, and repeatedly verifiable tilt detection operations in engineering sites. Summary of the Invention

[0006] To overcome the above deficiencies, the present invention provides a handheld tilt angle detection and marking tool, which overcomes or at least partially solves the above technical problems.

[0007] This invention provides a handheld tilt angle detection and marking tool, including a tool housing. The tool housing is a vertical cylindrical structure, which is divided into a front end, a cylindrical body section, and a rear end along the axial direction. The front end is provided with a marking impact rod, a measuring contact plane, and a front end limiting partition. The cylindrical body section is provided with a guide rod assembly, an energy storage spring, a sliding impact disc, a transmission rack, a first connecting bar, a middle base partition, a gear limiting pawl assembly, a reduction drive motor, a one-way clutch ratchet mechanism, and a forward and reverse gear set. The rear end is provided with a tail base partition, a return spring, a second connecting bar, an impact trigger button, and several control buttons.

[0008] Preferably, the marking impact rod is a cylindrical telescopic rod with a conical tip at the front end and a rigid connection between the rear end and the sliding impact disc. The marking impact rod passes through the marking impact rod guide bushing and achieves axial extension and contraction at the center of the measuring contact plane.

[0009] Preferably, the measuring contact plane is located at the front end of the tool, with an inlet and outlet for marking the impact rod at the center. A dual-axis tilt sensor is symmetrically integrated inside the measuring contact plane, and a ring-shaped lighting strip is arranged around the inlet and outlet.

[0010] Preferably, the guide rod assembly consists of three guide rods, with the upper end fixed to the middle base partition and the lower end fixed to the front limiting partition, arranged evenly in a Y-shape; the sliding impact disc has guide holes and is slidably fitted onto the guide rod assembly; the energy storage spring consists of three sets, each fitted onto one of the three guide rod assemblies, with the upper end of the energy storage spring abutting against the middle base partition and the lower end abutting against the upper surface of the sliding impact disc.

[0011] Preferably, the sliding striking disc has integrally formed transmission racks on both sides, and the upper and lower ends of the transmission racks on both sides are connected by a No. 1 connecting strip to form a frame-like integral structure; the output end of the reduction drive motor is connected to a forward and reverse gear set, which meshes with the transmission racks on both sides respectively, and a one-way clutch ratchet mechanism is provided inside the reduction drive motor.

[0012] Preferably, the outer wall of the cylinder section is symmetrically provided with two foldable assistive blades. The foldable assistive blades are normally folded and attached to the outer wall of the tool housing, and are folded outwards and unfolded when in use.

[0013] Preferably, a display screen and a lighting switch are embedded in the side wall of the cylinder section, and both the display screen and the lighting switch are flush with the outer wall of the tool housing; the rear end is provided with an on / off switch, a HOLD data lock button, a strike trigger button, a first-level energy storage button, a second-level energy storage button, and a third-level energy storage button.

[0014] Preferably, the gear limit pawl assembly is evenly arranged along the inner wall of the cylinder to limit the stroke of the sliding striking disc; the striking trigger button is mechanically connected to the gear limit pawl assembly via a second connecting strip, and the reset spring is connected to the gear limit pawl assembly to achieve reset.

[0015] Preferably, the rear end is provided with a main control circuit board and a rechargeable battery compartment, and the tool housing is provided with a charging port connected to the rechargeable battery compartment; the main control circuit board is electrically connected to the dual-axis tilt sensor, the ring lighting strip, the display screen, the reduction drive motor and each control button.

[0016] The targeted solution provided by this invention has the following beneficial effects: 1. This invention integrates a dual-axis tilt sensor directly into the measuring contact plane and arranges them symmetrically around the inlet and outlet of the marking impact rod. This allows the tool to simultaneously read the verticality and bidirectional tilt angle when it is in contact with the surface to be measured. Users do not need to use a level to align the tool or switch between measuring and marking tools repeatedly. The angle is displayed on the side screen at the same time as the tool is in contact. If the tool is not perpendicular, it can be adjusted immediately and the tool can be marked directly. This combines the two actions of measuring and marking into one. 2. This invention employs a structure of three Y-shaped guide rods evenly arranged and fixed at both ends, combined with three sets of separately fitted energy storage springs, a weighted sliding impact disc, and transmission racks on both sides, so that the impact force is stably concentrated on the central axis. The reduction drive motor drives the impact disc to move upward and compress the spring through the gear set, and multiple sets of one-way pawls on the inner wall of the cylinder limit different strokes, realizing the switching of multiple levels of impact force. Whether making color markings or permanent indentations, the appropriate force can be selected with one click to make marks of consistent depth and accurate position, avoiding slippage or misalignment. 3. This invention addresses situations where there is insufficient lighting or limited operating space at the construction site. A ring of lighting is installed around the inlet and outlet of the marking impact rod at the front end of the tool. A switch on the side wall can illuminate the measuring area with one click. At the same time, foldable auxiliary wings are designed on the left and right sides of the outer wall of the cylinder. When folded, they do not take up space, and when unfolded, they facilitate stable pressure application with both hands. Even in dark, high, or corner environments, users can clearly see the contact surface and apply force evenly, avoiding tool tilting or misalignment when pressing with one hand.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of 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, 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.

[0021] Example Reference Figures 1-10 This invention provides a technical solution: a handheld tilt angle detection and marking tool, including a tool housing 30, which is a vertical cylindrical structure, divided into a front end, a cylindrical body section and a rear end along the axial direction. The front end is provided with a marking impact rod 1, a measuring contact plane 4 and a front end limiting partition 5. The cylindrical body section is provided with a guide rod assembly 7, an energy storage spring 8, a sliding impact disc 9, a transmission rack 10, a first connecting bar 11, a middle base partition 12, a gear limiting ratchet assembly 14, a reduction drive motor 15, a one-way clutch ratchet mechanism 16 and a forward and reverse gear assembly 17. The rear end is provided with a tail base partition 32, a reset spring 31, a second connecting bar 33, an impact trigger button 26 and several control buttons.

[0022] Furthermore, the marking impact rod 1 is a cylindrical telescopic rod with a conical tip at the front end and a rigid connection between the rear end and the sliding impact disc 9. The marking impact rod 1 passes through the marking impact rod guide bushing 6 and achieves axial extension and contraction at the center of the measuring contact plane 4. In the free state, the rod head and part of the rod body of the marking impact rod 1 extend out of the center of the contact surface.

[0023] Furthermore, the measuring contact plane 4 is set at the front end of the tool, with an inlet and outlet for marking the impact rod 1 in the center. A dual-axis tilt sensor 3 is symmetrically integrated inside the measuring contact plane 4 and around the inlet and outlet, which can simultaneously detect the tilt angle in two orthogonal directions, realizing simultaneous measurement of verticality and bidirectional tilt. A ring-shaped lighting strip 2 is set around the inlet and outlet for supplemental lighting of the measuring point area in dark construction environments.

[0024] Furthermore, the guide rod assembly 7 consists of three guide rods, with the upper end fixed to the middle base partition 12 and the lower end fixed to the front limiting partition 5, arranged in a Y-shape to form a stable frame structure with fixed at both ends; the sliding impact plate 9 has guide sliding holes and is slidably fitted onto the guide rod assembly 7. The energy storage spring 8 consists of three sets, which are respectively sleeved on the three guide rod assemblies 7. The upper end of the energy storage spring 8 abuts against the middle base partition 12, and the lower end abuts against the upper surface of the sliding impact plate 9. When the sliding impact plate 9 moves upward, it compresses the three sets of springs simultaneously to achieve graded energy storage.

[0025] Furthermore, the sliding striking disc 9 has integrated transmission racks 10 on both sides. The upper and lower ends of the transmission racks 10 on both sides are connected by a connecting strip 11 to form a frame-like integral structure. The sliding striking disc 9 adopts a weighted structure design. The output end of the speed reduction drive motor 15 is connected to the forward and reverse gear set 17. The forward and reverse gear set 17 meshes with the transmission racks 10 on both sides respectively. The speed reduction drive motor 15 is equipped with a one-way clutch ratchet mechanism 16. When the energy is stored and the motor moves upward, the ratchet engages and drives the motor. When the motor moves downward and releases its energy, the ratchet rotates freely to prevent the motor from being driven in the opposite direction.

[0026] Furthermore, two foldable assistive blades 18 are symmetrically arranged on the left and right sides of the outer wall of the cylinder section. The foldable assistive blades 18 are normally folded and attached to the outer wall of the tool housing 30. When in use, they are folded outward to increase the gripping contact area and facilitate the application of stable axial pressing pressure.

[0027] Furthermore, a display screen 22 and a lighting switch 23 are embedded in the side wall of the barrel section. Both the display screen 22 and the lighting switch 23 are flush with the outer wall of the tool housing 30 and do not protrude from the outline. The display screen 22 is arranged laterally to display the tilt angle of the measured plane. The lighting switch 23 is used to control the opening and closing of the front ring lighting strip 2. The rear end is provided with an on / off switch 24, a HOLD data lock button 25, a strike trigger button 26, an energy storage level 1 button 27, an energy storage level 28, and an energy storage level 3 button 29. The on / off switch 24 controls the power on and off of the display screen. The HOLD data lock button 25 is used to lock the stable measurement value with one click. The energy storage level button is used to switch the strike intensity to adapt to the requirements of color marking or permanent indentation marking.

[0028] Furthermore, the gear limit pawl group 14 is evenly arranged along the inner wall of the cylinder, with a total of three groups of six one-way pawls, which are used to limit the stroke of the sliding striking disc 9. Different height slots correspond to different energy storage compression gears. The strike trigger button 26 is mechanically connected to the gear limit pawl group 14 via the second connecting strip 33. When pressed, the pawl retracts, and the energy storage spring instantly releases potential energy to drive the sliding strike disc and the marking impact rod to quickly pop out and complete the striking. The reset spring 31 is connected to the gear limit pawl group 14. When the strike trigger button is released, it drives the pawl to reset.

[0029] Furthermore, the rear end is equipped with a main control circuit board 19 and a rechargeable battery compartment 20, and the tool housing 30 is equipped with a charging port 21 connected to the rechargeable battery compartment 20; the main control circuit board 19 is electrically connected to the dual-axis tilt sensor 3, the ring lighting strip 2, the display screen 22, the geared drive motor 15 and various control buttons, respectively, to realize logic control and power supply functions such as motor start / stop, lighting on / off, data locking, and gear adjustment.

[0030] In practice Before use, the operator places the measuring contact plane 4 at the front end of the tool against the surface of the component to be measured. At this time, the dual-axis tilt sensor 3 integrated inside the plane begins to synchronously collect tilt angle data in two orthogonal directions. The sensor converts the mechanical tilt angle change into an electrical signal, which is transmitted to the main control circuit board 19 inside the rear for processing. The real-time angle value is then displayed on the side-mounted display screen 22. If the ambient light is insufficient, the ring-shaped lighting strip 2 set around the inlet and outlet of the marking impact rod 1 can be activated by the lighting switch 23 to ensure that the measuring point area is clearly visible. When the reading is stable, the HOLD data lock button 25 is pressed, and the main control circuit board 19 immediately locks the current measurement value for comparison or recording, providing a basis for whether to perform marking impact in the future. Depending on the hardness of the material to be marked or the required marking depth, the operator selects the striking force using the first energy storage button 27, the second energy storage button 28, or the third energy storage button 29. After receiving the gear command, the main control circuit board 19 starts the reduction drive motor 15. Its output end meshes with the transmission racks 10 on both sides of the sliding striking disc 9 through the forward and reverse gear set 17. The sliding striking disc 9 moves upward along the guide rod assembly 7, synchronously compressing the energy storage spring 8 sleeved on the three guide rods. When the sliding striking disc 9 reaches the corresponding gear height, the three sets of gear limit pawls 14, which are evenly arranged along the inner wall of the cylinder, with a total of six one-way pawls, mechanically lock its position. The one-way clutch ratchet mechanism 16 set inside the reduction drive motor 15 maintains the meshing transmission when the energy storage moves upward to prevent energy backflow. After confirming the tilt angle is qualified and energy storage is completed, the operator holds the rear end of the tool and presses the strike trigger button 26. This button is mechanically connected to the gear limit pawl group 14 through the second connecting bar 33. At the moment of pressing, all the pawls retract synchronously, releasing the constraint on the sliding strike disc 9. The three energy storage springs 8 release all their potential energy at the same time, driving the sliding strike disc 9 to descend at high speed along the guide rod assembly 7. This causes the marking impact rod 1, which is rigidly connected to it, to quickly pop out from the center inlet and outlet of the measuring contact plane 4. The front conical tip strikes the plane to be measured to complete the color marking or permanent indentation marking. After the impact, the reset spring 31 connected to the gear limit pawl group 14 automatically drives the pawls to return to the initial locking state. During the downward release process of the sliding strike disc 9, the one-way clutch ratchet mechanism 16 turns into free rotation to prevent reverse drive of the reduction drive motor 15.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
