Description

Technical Field

[0001] This utility model relates to the field of building construction surveying technology, and in particular to an adjustable-angle laser rangefinder. Background Technology

[0002] A laser rangefinder is a precision instrument that calculates distance using the reflection time of a laser pulse. It features high precision, non-contact measurement, and fast response.

[0003] Patent specification CN219328897U discloses an adjustable-angle laser rangefinder device, comprising: a base; a movable seat disposed above the base, a mounting seat fixedly mounted on the movable seat, a frame rotatably mounted on the mounting seat via a pivot, and a laser rangefinder hinged to the frame via a pin; and a lifting mechanism for adjusting the height of the laser rangefinder. The device first adjusts the height of the laser rangefinder via the lifting mechanism, then rotates the frame to adjust the orientation of the laser rangefinder, and finally directly deflects the laser rangefinder to adjust its angle, thereby adjusting the laser rangefinder to the target position and angle to meet actual measurement needs. This eliminates the need for manual operation, offering convenience and labor-saving features while ensuring the measurement accuracy of the laser rangefinder.

[0004] However, in implementing the relevant technology, the above-mentioned adjustable-angle laser rangefinder has the following problems: the height of the laser rangefinder is adjusted by a lifting mechanism, but the vibration generated by the lifting mechanism during operation may cause errors in the height adjustment of the laser rangefinder. In addition, the laser rangefinder is fixedly connected to the mounting base, which is not conducive to carrying. In scenarios where the measurement location needs to be moved frequently, it is not convenient to carry, which reduces the versatility of the device. In view of this, an adjustable-angle laser rangefinder is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-angle laser rangefinder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable-angle laser rangefinder device, comprising a tripod, a base plate fixedly connected to the upper end of the tripod, an adjusting circular plate fixedly connected to the upper end of the base plate, a connecting circular plate rotatably connected to the upper end of the adjusting circular plate, a circular clamping plate attached to the upper end of the connecting circular plate, a laser rangefinder body fixedly connected to the upper end of the circular clamping plate, a spirit level fixedly connected to the upper edge of the base plate, a damping circular plate fixedly connected to the lower end of the connecting circular plate, a hollow block fixedly connected inside the adjusting circular plate, a bidirectional threaded rod rotatably connected inside the hollow block, a damping plate threadedly connected to the outer side of the bidirectional threaded rod, and adjusting knobs fixedly connected to the left and right ends of the bidirectional threaded rod.

[0007] As a further description of the above technical solution: the outer side of the damping circular plate is in contact with the inner wall of the adjusting circular plate, the outer side of the damping circular plate is in contact with the inner wall of the damping plate, and the front and rear ends of the damping plate are slidably connected to the inside of the adjusting circular plate, so that the damping circular plate generates resistance when the inner wall of the adjusting circular plate rotates, which facilitates the control of the angle adjustment of the laser rangefinder body.

[0008] As a further description of the above technical solution: the upper end of the adjusting circular plate is provided with a circular groove, and the diameter and depth of the circular groove are matched with the diameter and depth of the damping circular plate, so that the damping circular plate can rotate inside the adjusting circular plate.

[0009] As a further description of the above technical solution: the adjusting circular plate has a positioning groove inside, and the shape and size of the positioning groove cross-section are matched with the shape and size of the damping plate cross-section, so that the damping plate can move in the positioning groove inside the adjusting circular plate.

[0010] As a further description of the above technical solution: the adjusting circular plate has a hollow structure inside, and the hollow block and the bidirectional threaded rod are both inside the hollow structure. The hollow block has through holes at both ends, and the diameter of the through holes matches the diameter of the bidirectional threaded rod. The rotation of the bidirectional threaded rod drives the damping plate to move, thereby clamping the damping circular plate and increasing the friction.

[0011] As a further description of the above technical solution: the left and right ends of the adjustment disc are provided with through circular holes, and the diameter of the circular holes matches the diameter of the bidirectional threaded rod, so that the bidirectional threaded rod passes through the adjustment disc and connects to the adjustment knob, and the damping plate is adjusted by rotating the adjustment knob.

[0012] As a further description of the above technical solution: a first spring is fixedly connected inside the circular card plate, and a card block is fixedly connected to the end of the first spring away from the circular card plate. A second spring is fixedly connected inside the connecting circular plate, and an arc plate is fixedly connected to the end of the second spring away from the connecting circular plate. A button is fixedly connected to the outside of the arc plate, so that the arc plate moves inward, pushing the card block into the circular card plate, thereby separating the connecting circular plate from the circular card plate.

[0013] As a further description of the above technical solution: the circular card plate has a card slot inside, and the shape and size of the card slot cross-section match the shape and size of the card block cross-section. The connecting circular plate has a groove inside, and the shape and size of the groove cross-section match the shape and size of the card block cross-section. This allows the connecting circular plate to be separated from the circular card plate by pressing the button, facilitating the quick disassembly of the device.

[0014] This utility model has the following beneficial effects:

[0015] The adjustable-angle laser rangefinder designed in this invention utilizes the coordinated design of an adjusting circular plate and a damping circular plate to provide appropriate resistance during angle adjustment, preventing overshoot during adjustment. By rotating the adjustment knob, the damping plate clamps onto the damping circular plate, increasing damping and helping to accurately lock onto the target direction. At the same time, it keeps the instrument stable before locking, reducing the impact of hand tremors or external interference on measurement accuracy.

[0016] The adjustable-angle laser rangefinder device designed in this utility model, through the design and cooperation of the locking block and the arc plate, allows the laser rangefinder body to be separated from the tripod, making it easy to carry and operate by hand. At the same time, multiple locking blocks set inside the circular locking plate engage the connecting circular plate, making the engagement between the circular locking plate and the connecting circular plate more secure. By pressing the button, the locking block can be pushed into the circular locking plate, realizing the separation of the laser rangefinder body from the tripod. Attached Figure Description

[0028] As a further implementation of the above technical solution: a circular groove is provided at the upper end of the adjusting circular plate 3, and the diameter and depth of the circular groove are matched with the diameter and depth of the damping circular plate 8, so that the damping circular plate 8 can rotate inside the adjusting circular plate 3.

Adjust the damping of the laser rangefinder body 6. At the same time, press the button 17, so that the arc plate 16 compresses the second spring 15 and pushes the clamping block 14 to retract into the circular clamping plate 5, so that the laser rangefinder body 6 can be separated from the tripod 1.
