Description

Technical Field

[0001] This application relates to the field of building construction equipment, and in particular to a measuring device for building construction. Background Technology

[0002] During house construction, measuring tools are often needed to measure the length, flatness, and distance of the house walls, providing effective support for the design and construction of the building.

[0003] Chinese utility model patent CN221406030U discloses a distance measuring device for building construction, including a fixed base, a measuring platform mounted above the fixed base for support, a laser distance measuring instrument placed on the upper part of the measuring platform, support legs rotatably connected to a side plate, the support legs being set at equal angles at the edges of the fixed base, and the support legs forming a flip-up structure on the outside of the fixed base, an adjusting column inserted into the middle of the fixed base, and a slotted connection between the adjusting column and a protruding rod, with the measuring platform fixedly connected to the upper end of the adjusting column. The laser distance measuring instrument is detachable via a fixing clamp on the upper part of the measuring platform. This distance measuring device for building construction facilitates height adjustment of the laser distance measuring instrument, as well as positioning and disassembly maintenance. The flip-up support legs on the side of the fixed base and the downward sliding and retracting fixing holes facilitate folding and storage of the device, improving its overall portability.

[0004] In actual use, although the laser distance measuring instrument is relatively easy to disassemble, the overall installation and fixation of the laser distance measuring instrument is not secure enough by clamping it with a fixing plate. There is a risk that the laser distance measuring instrument may fall off. In addition, only the laser distance measuring instrument is easy to disassemble. The fixing base and support legs cannot be disassembled, making it difficult to store. Utility Model Content

[0005] In order to ensure that the laser distance measuring instrument is securely installed and that the mounting base and support legs are easy to disassemble, this application provides a measuring device for building construction.

[0006] This application provides a measuring device for building construction, which adopts the following technical solution:

[0007] A measuring device for building construction includes a mounting base, a laser distance measuring instrument, and several support legs. It also includes a disassembly and assembly assembly, which is configured to correspond one-to-one with each support leg. The support legs are rotatably mounted on the bottom of the mounting base via the disassembly and assembly assembly. The device also includes a lifting assembly, on which the laser distance measuring instrument is threadedly connected. The lifting assembly is used to vertically raise and lower the laser distance measuring instrument.

[0008] By adopting the above technical solution, the support feet and mounting base on the measuring device can be disassembled and installed through the disassembly and assembly components, which facilitates the disassembly of the support feet and makes the measuring device easy to store. The laser distance measuring instrument is threadedly connected to the lifting assembly, and the threaded connection makes the laser distance measuring instrument fixed in place. At the same time, the laser distance measuring instrument is easy to disassemble and is firmly installed. The fixed base and support legs are easy to disassemble.

[0009] Optionally, the mounting base is provided with a plurality of fixed seats corresponding one-to-one with the support feet. The disassembly and assembly assembly includes a connecting column and a compression spring. One end of the connecting column is provided with a limiting ring block. The compression spring is sleeved on the connecting column. One end of the compression spring is provided with the limiting ring block, and the other end is provided with the fixed seat. The spring force direction is the same as the length direction of the connecting column. The fixed seat is provided with a through hole, and the support foot is provided with a rotating groove. The connecting column passes through the through hole and the rotating groove, and the compression spring drives the connecting column to firmly limit the support foot.

[0010] By adopting the above technical solution, when installing the support foot, pulling the connecting column stretches the compression spring, allowing the support foot to be placed into the fixed seat. The connecting column passes through the through hole and the rotating groove, completing the limit of the support foot. The compression spring compresses the connecting column, making it securely engaged. When disassembling, pulling the connecting column allows the support foot to detach, making the installation and disassembly of the support foot and the mounting seat convenient.

[0011] Optionally, the connecting column is provided with two sets of sliding components. The sliding components include a sliding block and a sliding spring. The connecting column is provided with a sliding groove for the sliding block to slide. One end of the sliding spring is located at the bottom of the sliding groove, and the other end is located on the sliding block. The spring force direction of the sliding spring is the same as the sliding direction of the sliding block. The sliding spring drives the sliding block to protrude from the connecting column, and the sliding block is engaged with the fixed seat.

[0012] By adopting the above technical solution, after the support foot is firmly engaged, the sliding spring drives the sliding block to protrude and connect. The sliding block engages with the fixed seat, further limiting the connection column and making it easier for the connection column to detach from the support foot. When the connection column needs to detach, the user presses the sliding block to make it slide along the bottom of the sliding groove. At this time, the connection column can detach, further improving the installation firmness of the mounting seat and the support foot.

[0013] Optionally, the lifting assembly includes a threaded rod, the mounting base has a threaded hole, the threaded rod is threadedly connected to the threaded hole, and the bottom of the laser distance measuring instrument is provided with a mounting sleeve, which is threadedly connected to the end of the threaded rod.

[0014] By adopting the above technical solution, the lifting component raises and lowers the laser distance measuring instrument, making it easy to adjust the height of the laser distance measuring instrument. The laser distance measuring instrument is fixed on the mounting block, and the mounting block is threadedly connected to the end of the threaded rod, making it convenient to install and disassemble the laser distance measuring instrument.

[0015] Optionally, anti-detachment blocks are provided on both sides of the end of the sliding block near the sliding spring, and anti-detachment grooves are provided on the side wall of the sliding groove for the anti-detachment blocks to slide.

[0016] By adopting the above technical solution, the anti-detachment block and the anti-detachment groove are used to prevent the sliding block from sliding out of the connecting column, and at the same time make the sliding block slide stably.

[0017] Optionally, the lifting assembly further includes a turntable, which is located at the end of the threaded rod away from the mounting base, and a handle is eccentrically mounted on the turntable.

[0018] By adopting the above technical solution, the rotation of the threaded rod is facilitated by the turntable and handle, making it convenient to raise and lower the laser distance measuring instrument.

[0019] Optionally, the support foot includes a support cylinder and a telescopic rod. The telescopic rod is slidably disposed inside the support cylinder and slides along the length direction of the support cylinder. A limit post is provided on the support cylinder. The limit post passes through and is threadedly connected to the support cylinder. A plurality of limit holes are opened on the telescopic rod. When the limit post is located in the limit hole, the telescopic rod is limited.

[0020] By adopting the above technical solution, the height of the measuring device can be adjusted by using the support cylinder and telescopic rod. Combined with the lifting component, the measuring device has two height adjustment methods, making the height adjustment more flexible.

[0021] Optionally, a limiting sleeve is provided at the bottom of the mounting base, and the limiting sleeve is sleeved on the threaded rod.

[0022] By adopting the above technical solution, the threaded rod is stabilized during lifting and lowering by the limiting sleeve, and its direction is not easily deviated.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The support feet and mounting base on the measuring device are disassembled and installed through the disassembly and assembly components.
