Description

Technical Field

[0001] This application relates to the technical field of laser rangefinders, and in particular to a laser rangefinder for building inspection. Background Technology

[0002] In housing construction projects, the accuracy of measurement work directly affects the quality of the project. Traditional measuring tools, such as tape measures, are cumbersome to operate and their accuracy is greatly affected by human factors. Therefore, laser rangefinders are needed.

[0003] Existing laser rangefinders typically require a tripod for use, meaning they are supported in mid-air by a tripod. This means that the laser rangefinder must be fixed to the tripod every time it is used. The current fixing method is usually a bolt connection, which can be relatively troublesome when frequent disassembly is required. Therefore, further improvements are needed. Utility Model Content

[0004] To address the above problems, this application provides a laser rangefinder for building inspection.

[0005] This application provides a laser rangefinder for building inspection, which adopts the following technical solution: A laser rangefinder for building inspection includes a rangefinder body, a mounting base for mounting the rangefinder body, a tripod mounted on the mounting base, and a connecting assembly for detachably connecting the rangefinder body to the mounting base. The connecting assembly includes a plug-in portion disposed at the lower end of the rangefinder body, a limiting rod disposed on the mounting base, an elastic element for moving the limiting rod toward the plug-in portion, and a control element for controlling the limiting rod to slide away from the plug-in portion. The upper surface of the mounting base has a slot for the plug-in portion to be inserted into, and the plug-in portion has a limiting hole for the limiting rod to be inserted into.

[0006] By adopting the above technical solution, before the connector is inserted into the slot, the control component drives the limit rod to retract. After the connector is inserted into the slot, the force applied to the control component is released. At this time, the limit rod slides into the limit hole under the action of the elastic component. Compared with bolts, this allows for a quick connection between the rangefinder body and the mounting base, which is simple to operate and highly stable. The design of the control component allows the user to manually control the limit rod to slide away from the connector, further simplifying the disassembly process, improving efficiency, and making the connection between the rangefinder body and the mounting base relatively fast.

[0007] Preferably, guide grooves are symmetrically formed on the opposite side walls of the insertion part.

[0008] By adopting the above technical solution, the symmetrical opening of guide grooves on the opposite side walls of the connector effectively improves the assembly accuracy between the connector and the mounting base, making the connector smoother when inserted into the slot, reducing offset or jamming during assembly, and thus improving the stability of the rangefinder body installation. Furthermore, the guide groove design also enhances the structure's guiding properties, reducing the risk of component damage due to improper operation.

[0009] Preferably, the connection assembly further includes a magnetic absorbing sheet built into the plug portion and a magnetic absorbing block magnetically attracted to the magnetic absorbing sheet, wherein the magnetic absorbing block is installed in the mounting base.

[0010] By adopting the above technical solution, the magnetic connection between the magnetic accumulator and the magnetic block can enhance the connection stability between the plug and the mounting base, and reduce the loosening of the rangefinder body due to vibration or external force during use.

[0011] Preferably, the control component includes a toggle block disposed on the limiting rod, the side wall of the mounting base is provided with a through groove for the limiting rod to pass through, the through groove is connected to the slot, the toggle block is embedded in the through groove, the elastic element is built into the through groove, and the two ends of the elastic element are respectively connected to the inner wall of the through groove and the surface of the toggle block near the limiting rod.

[0012] By adopting the above technical solution, the actuating block is set on the limiting rod and embedded in the through groove, allowing the user to control the sliding of the limiting rod by actuating the block. This enables the limiting rod to quickly disengage or insert with the connector, facilitating the installation and disassembly of the rangefinder body. This design effectively simplifies the connection operation between the rangefinder body and the mounting base, improving ease of use.

[0013] Preferably, the outer surface of the actuating block is provided with an elastic pad, the outer surface of the elastic pad is provided with anti-slip texture, and the actuating block is partially exposed in the groove.

[0014] By adopting the above technical solution, and by setting an elastic pad, it can be relatively stably embedded in the slot, and corresponding anti-slip texture is opened, so that the user can obtain better friction when operating the toggle block, thereby making it easier to control the limit rod to slide out of the plug part.

[0015] Preferably, the mounting base is provided with a cleaning component for cleaning dust from the lens of the rangefinder body.

[0016] By adopting the above technical solution, the cleaning component installed on the mounting base can effectively remove dust from the lens of the rangefinder body, thereby improving the measurement accuracy and reliability of the laser rangefinder during use.

[0017] Preferably, the mounting base has a storage cavity for storing gas. The cleaning assembly includes a piston rod slidably connected to the storage cavity, a connecting rod connected to the piston rod, and an air blowing pipe communicating with the storage cavity to blow air toward the lens on the rangefinder body. The mounting base has an air inlet, and a first one-way valve is provided at the air inlet. The flow direction of the first one-way valve is from outside the mounting base to inside the storage cavity. A second one-way valve is provided inside the air blowing pipe. The flow direction of the second one-way valve is from inside the storage cavity to inside the air blowing pipe. The connecting rod is connected to the limiting rod.

[0018] By adopting the above technical solution, when the limiting rod moves away from the limiting hole, the outside air flows into the storage cavity through the first one-way valve. When the limiting rod moves closer to the limiting hole, it drives the piston rod to compress the air in the storage cavity and allow it to flow through the second one-way valve to the air blowing pipe to blow air onto the lens, effectively removing dust from the lens surface and improving measurement accuracy and reliability.

[0019] Preferably, the upper surface of the mounting base is provided with a mounting hole for installing the air blowing pipe, the mounting base is provided with an elastic airbag in the slot, and the mounting base is provided with a connecting groove in the slot that communicates with the storage cavity.

[0020] By adopting the above technical solution, an elastic airbag is installed inside the slot, which provides buffer protection when the rangefinder body is inserted, reducing the impact of vibration on the device. At the same time, a connecting groove is opened in the slot to connect the elastic airbag to the storage cavity, so that when the elastic airbag is compressed, gas can be introduced into the storage cavity, thereby enhancing the gas storage capacity of the cleaning component and improving the lens cleaning effect.

[0021] In summary, this utility model has the following beneficial effects: By cooperating with the plug-in part, limit rod, elastic element and control element in the connecting assembly, a quick and detachable connection between the rangefinder body and the mounting base is achieved, which significantly improves the efficiency of disassembly and assembly, while ensuring the firmness of the connection.

In this embodiment, the plug-in portion 41 is a rectangular plug, and guide grooves 411 are symmetrically provided on the opposite side walls of the plug-in portion 41 so that the cross-sectional area of ​​the plug-in portion 41 gradually decreases in the direction away from the rangefinder body 1. The upper surface of the mounting base 2 is provided with a slot 21 for the plug-in portion 41 to be inserted, and the plug-in portion 41 is provided with a limiting hole 412 for the limiting rod 42 to be inserted.

[0028] The mounting base 2 has a through groove 22 on its side wall for the limit rod 42 to pass through. The through groove 22 is connected to the slot 21. The elastic element 43 is a spring, which is built into the through groove 22. The two ends of the elastic element 43 are respectively connected to the inner wall of the through groove 22 and the surface of the toggle block near the limit rod 42.

[0029] In this embodiment, the control component 44 is a toggle block disposed on the limiting rod 42. The toggle block is fixedly connected to the end of the limiting rod 42 away from the limiting hole 412. The toggle block is embedded in the through groove 22, and a portion of the toggle block is exposed outside the through groove 22. An elastic pad 441 is wrapped around the outer surface of the toggle block. The toggle block drives the elastic pad 441 to be partially embedded in the through groove 22. The outer surface of the elastic pad 441 is provided with anti-slip texture 442 to increase the friction during operation.

[0030] Furthermore, the mounting base 2 is provided with a cleaning component 5 for cleaning dust from the lens of the rangefinder body 1. The mounting base 2 has a storage chamber 23 for storing gas. The cleaning component 5 specifically includes a piston rod 51 slidably connected to the storage chamber, a connecting rod 52 connected to the piston rod 51, and an air blowing pipe 53 connected to the storage chamber 23 for blowing air towards the lens of the rangefinder body 1.
