Description

Technical Field

[0001] This utility model belongs to the field of surveying ruler technology, specifically relating to an adjustable intelligent surveying ruler. Background Technology

[0002] Surveying rulers are professional tools used for measurement and drawing. They are typically made of high-precision materials and feature clear graduations and multifunctional designs (such as rulers, set squares, and measuring tapes). They can accurately measure lengths and angles or assist in drawing diagrams. Widely used in civil engineering, architectural planning, and geographical surveying, they balance portability and durability, making them essential tools for engineers and draftsmen. Some surveying rulers also include a scale conversion function for quick conversion between drawings and actual dimensions.

[0003] A known authorized patent with application number 202322804706.0 discloses a surveying ruler for mapping: a support plate with a measuring ruler fixedly connected to its inner side. This utility model, by setting a measuring ruler, allows for the measurement of the length of an object. After measurement, pulling a lever allows the surveying pen to move linearly for drawing, improving the convenience of the surveying equipment. The inclusion of a movable stud allows the locking block to move, facilitating adjustment of its range of motion and improving the stability of the mapping device. The use of a circular ruler allows the object to be measured to be placed between a fixed plate and a rotating plate, and then the rotating plate is rotated to clamp the object with the fixed plate, thus measuring the object's angle and expanding the device's measurement range. Finally, the inclusion of a diameter ruler allows for the measurement of the object's diameter after clamping it with the clamping plate, further expanding the device's measurement range and solving the problem of the surveying ruler's relatively limited function.

[0004] However, in implementing the relevant technology, the following problems were found with the above technical solution: when in use, the device can only measure smaller objects, and it is difficult to accurately measure larger objects such as those inside a house.

[0005] Therefore, an adjustable intelligent surveying ruler is proposed to solve the above problems. Utility Model Content

[0006] This invention proposes an adjustable intelligent measuring ruler, which solves the problem in related technologies that the device can only measure smaller objects and is difficult to accurately measure larger items such as those inside a house.

[0007] The technical solution of this utility model is as follows: an adjustable intelligent measuring ruler, including: a horizontal ruler, a movable base and a braking component, wherein a locking block is provided at the bottom of the movable base, the locking block is slidably connected to the inner wall of the horizontal ruler, and the braking component is provided on the outer wall of the movable base.

[0008] An angle sensor is provided on the outer wall of the movable seat, a fixed block is provided at the detection end of the angle sensor, and a laser rangefinder is placed above the fixed block.

[0009] The angle sensor's detection end is equipped with a through-braking assembly;

[0010] The outer wall of the ruler is provided with length markings, and the outer wall of the fixing block is provided with angle markings.

[0011] Preferably, the braking assembly includes a support arm, a fixed housing, a spring, and a friction block. The support arm is fixedly connected to the outer wall of the movable seat, the fixed housing is disposed at the top of the support arm, the friction block is sleeved inside the fixed housing, one end of the spring is fixedly connected to the inner wall of the fixed housing, the other end of the spring is fixedly connected to the outer wall of the friction block, and the inner wall of the friction block is in close contact with the detection end of the angle sensor.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Implementation

[0026] Please see Figure 1 -4. Adjustable intelligent measuring ruler, including: horizontal ruler 1, movable base 2 and braking component 4. The bottom of the movable base 2 is provided with a locking block 12, which is slidably connected to the inner wall of the horizontal ruler 1. The braking component 4 is provided on the outer wall of the movable base 2.

[0027] An angle sensor 3 is provided on the outer wall of the movable base 2. A fixed block 8 is provided on the detection end of the angle sensor 3. A laser rangefinder 5 is placed on top of the fixed block 8.

[0028] Angle sensor 3 is equipped with a through-braking assembly 4 at its detection end;

[0029] The outer wall of the horizontal ruler 1 is provided with length markings 16, and the outer wall of the fixing block 8 is provided with angle markings 17.

[0030] The technical solution provided in this embodiment is as follows: When using the device, first place it on the ground. If placed in a corner, the vertical ruler 14 should be pressed tightly against the wall. Then, use the optical difference measuring level tube 15 to verify the overall levelness of the device. First, start the laser rangefinder 5, then observe the attitude level tube 10. If imbalance is found, adjust it promptly. After adjustment, zero the angle sensor 3. After zeroing, measure using the laser rangefinder 5. If tilt measurement is required, simply rotate the fixed block 8. During rotation, the angle sensor 3 records the rotation angle in real time, then brakes. The friction block 44 in component 4, under the action of spring 43, continuously brakes the detection end of angle sensor 3, ensuring that the laser rangefinder 5 can be suspended at any angle when it rotates, so that the angle will not change during measurement. If it is necessary to move the position of laser rangefinder 5, the drive motor 13 can be started. The drive motor 13 drives the moving screw 11 to rotate, and the moving screw 11 drives the threadedly connected locking block 12 to move, so that the position of laser rangefinder 5 can be moved. During the movement, the distance moved is measured through length scale 16 to ensure that the actual movement distance is the same as the actual distance.

[0031] Furthermore, the braking assembly 4 includes a support arm 41, a fixed housing 42, a spring 43, and a friction block 44. The support arm 41 is fixedly connected to the outer wall of the movable seat 2. The fixed housing 42 is disposed at the top of the support arm 41. The friction block 44 is sleeved inside the fixed housing 42. One end of the spring 43 is fixedly connected to the inner wall of the fixed housing 42, and the other end of the spring 43 is fixedly connected to the outer wall of the friction block 44. The inner wall of the friction block 44 is in close contact with the detection end of the angle sensor 3.

[0032] Specifically, the braking component 4 can effectively suppress unexpected changes in the angle of the angle sensor 3 caused by the weight of the laser rangefinder 5 or other reasons, which would lead to inaccurate measurement results and large errors.

[0033] Furthermore, a fixed side plate 6 is provided at the top of the fixed block 8, and a rear plate 9 is fixedly provided at the top of the fixed block 8. The laser rangefinder 5 is located between the fixed side plate 6 and the rear plate 9, and a bidirectional screw 7 is connected to the internal thread of the fixed side plate 6.

[0034] Specifically, the fixed side plate 6 and the rear plate 9 can fix the laser rangefinder 5 in a relatively simple way. Then, by rotating the bidirectional screw 7, the two fixed side plates 6 can move relative to each other to clamp the laser rangefinder 5, which improves the accuracy of single-sided fixation.

[0035] Furthermore, a movable screw 11 is rotatably connected to the inner wall of the horizontal ruler 1, the inner wall of the locking block 12 is threadedly connected to the outer wall of the movable screw 11, and a drive motor 13 is fixedly installed inside the horizontal ruler 1, with the output end of the drive motor 13 fixedly connected to one end of the movable screw 11.

[0036] Specifically, by setting the movable screw 11, the drive motor 13 can rotate the movable screw 11, causing the locking block 12 to drive the movable seat 2 to move. At the same time, after the movement, due to the self-locking property of the screw, the accidental movement of the movable seat 2 can be prevented.

[0037] Furthermore, the outer wall of the fixed block 8 is provided with an attitude level tube 10, and the outer wall of the fixed side plate 6 is provided with an attitude level tube 10, and the angles between the attitude level tubes 10 are perpendicular to each other.

[0038] Specifically, the attitude level tube 10 can effectively and intuitively observe the angle of the fixed block 8 and perform timely calibration to avoid errors caused by angle issues during measurement.

[0039] Furthermore, a measuring level tube 15 is provided on the outer wall of the horizontal ruler 1, and vertical rulers 14 are provided at both ends of the horizontal ruler 1. A measuring level tube 15 is provided on the outer wall of the vertical ruler 14, and the measuring level tubes 15 are perpendicular to each other.

[0040] Specifically, the level tube 15 can detect the overall level and verticality of the equipment, enabling the equipment to measure the levelness of the ground and other surfaces.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
