Technical Field

[0001] This application relates to the field of building surveying technology, and in particular to portable municipal building surveying devices. Background Technology

[0002] Building surveying, also known as building construction surveying, is an indispensable part of the building construction process. It involves a comprehensive and in-depth investigation and analysis of the natural conditions of the proposed building site, such as geology, topography, landforms, hydrology, and climate, as well as the surrounding environment, transportation, supporting facilities, and other socio-economic conditions. Infrared rangefinders are required in building surveying.

[0003] The existing patent document "CN212646988U A Handheld Laser Rangefinder" discloses a laser rangefinder. Although the laser rangefinder in the above technical solution can be used for surveying during building construction, it is used when handheld. Especially when used in a more complex environment, the user is prone to instability and dropping the device when holding it for a long time. At the same time, in outdoor construction sites, dust and foreign objects are easy to adhere to the lens of the rangefinder, resulting in measurement errors.

[0004] In other words, existing technologies have the following technical problems: when ordinary laser rangefinders are used handheld in complex environments, prolonged handheld use can easily lead to instability and loss of control. Therefore, a portable municipal building surveying device is proposed to address these issues. Summary of the Invention

[0035] Auxiliary grip component 2 is fixedly disposed on the bottom surface of the infrared rangefinder body 1. The auxiliary grip component 2 is used to assist in fixing the infrared rangefinder body 1 when it is held in hand.

[0036] Lens protection component 3 is fixedly installed on the side wall of the outer shell of the infrared rangefinder body 1. The lens protection component 3 is used to protect the lens 102. When holding and measuring, the lens protection component 3 automatically opens.

[0037] Through the above technical solution, the auxiliary grip component 2 effectively provides auxiliary fixation between the fingers during handheld use, ensuring grip strength and preventing accidental slippage. The included ring 203 allows for convenient hanging on a backpack hook or other location when not in use, improving portability. Furthermore, to prevent dust and foreign matter from contaminating the lens during prolonged use at outdoor construction sites, this application designs a lens protection component 3. This component automatically shields and protects the lens when not in use, and automatically flips open when handheld, offering flexible and convenient use suitable for widespread adoption.

[0038] The auxiliary grip component 2 includes a rectangular fixed base 201, a sliding plate 202, a finger ring 203 and a connecting spring 204. The rectangular fixed base 201 is fixedly installed at the bottom of the infrared rangefinder body 1. The rectangular fixed base 201 has an inner cavity, and the sliding plate 202 is slidably connected in the inner cavity of the rectangular fixed base 201.

[0039] A finger ring 203 is fixedly connected to the bottom end of the sliding plate 202. With this technical solution, when the user holds the device for measurement, the user's thumb can be inserted into the inside of the finger ring 203 to hold the infrared rangefinder body 1. The finger ring 203, set on the user's thumb, can play an auxiliary role in fixing it and prevent it from slipping out of the hand due to unstable grip.

[0040] The lens protection assembly 3 includes a fixed shell 301, a movable seat 302, a connecting frame 303, a fixed foot 304, a flip frame 305, a protective baffle 306, a fixed guide rod 307, a limiting slider 308, a return spring 309, a contact plate 310, a spacer plate 311, and a swing arm 313. The fixed shell 301 is fixedly installed on the side wall of the outer shell of the infrared rangefinder body 1. The spacer plate 311 is fixedly connected in the inner cavity of the fixed shell 301. One end of the sliding plate 202 extends into the inner cavity of the fixed shell 301. One end of the connecting spring 204 is fixedly connected to the upper end of the sliding plate 202. The other end of the connecting spring 204 is fixedly connected to the bottom surface of the spacer plate 311.

[0041] A fixed guide rod 307 is fixedly connected to the inner cavity of the fixed housing 301. A limiting slider 308 is slidably connected to the fixed guide rod 307. One end of a return spring 309 is fixedly connected to one side wall of the limiting slider 308. The other end of the return spring 309 is fixedly connected to the inner cavity side wall of the fixed housing 301.

[0042] A fixed shaft 312 is fixedly connected to the partition plate 311, and a swing arm 313 is rotatably connected to the fixed shaft 312. The bottom end of the swing arm 313 contacts the upper surface of the sliding plate 202, and the upper end of the swing arm 313 contacts the side wall of the contact plate 310. With this technical solution, when the user holds the device, applying a certain gripping force to the sliding plate 202 can push the sliding plate 202 to move upward. The upward movement of the sliding plate 202 can push the swing arm 313 to rotate. The rotation of the swing arm 313 can push the contact plate 310 to move to the right, thereby driving the limiting slider 308 to move.

[0043] A movable seat 302 is slidably connected to the outer wall of the fixed shell 301. The movable seat 302 is fixedly connected to the limiting slider 308. With this technical solution, when the limiting slider 308 moves, it can drive the movable seat 302 to move.
