Description

Technical Field

[0001] This utility model belongs to the field of building distance measurement technology, and in particular a distance measuring instrument for building construction. Background Technology

[0002] A building rangefinder is a distance measuring instrument used to measure the distance to a target and calculate flight paths. Specifically, a building rangefinder includes a leg assembly and a rangefinder body mounted on the leg assembly. The leg assembly supports the rangefinder body on a load-bearing surface such as the ground to achieve distance measurement. In practical use, a protective shell is designed to protect the rangefinder; however, many protective structures are enclosed, making manual adjustment inconvenient during use.

[0003] A search revealed a Chinese patent document (authorization announcement number CN220016880U) regarding a distance measuring device for building construction, comprising a distance measuring device body and a leg assembly. The leg assembly includes a first leg and a second leg. The top end of the first leg is connected to the distance measuring device body, and the bottom end of the second leg is disposed on a bearing surface. The top end of the second leg is rotatably connected to the bottom end of the first leg, and the first leg has a receiving cavity for housing the second leg, allowing the second leg to rotate relative to the first leg to be housed within the receiving cavity or to rotate out of the receiving cavity. A locking structure is provided between the second leg and the first leg. When the distance measuring device for building construction is not in use, the second leg can be rotated and folded into the receiving cavity to reduce the overall size of the distance measuring device, thus facilitating portability. When the distance measuring device for building construction is needed, the second leg can be rotated out of the receiving cavity and locked by the locking structure, so that the second leg is in an unfolded state, facilitating installation on the bearing surface for distance measurement. The aforementioned patent designs a protective frame to protect the rangefinder, but the protective frame is enclosed, making it inconvenient to manually adjust during use. Utility Model Content

[0004] The purpose of this utility model is to provide a distance measuring instrument for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distance measuring instrument for building construction, comprising:

[0006] The rangefinder itself is used for measuring distances to buildings;

[0007] The protective frame is used to protect the rangefinder body. The inner top wall of the protective frame is rotatably connected to two movable plates for sealing the protective frame via a damping shaft. The movable plates and the sides of the protective frame are all embedded with viewing windows.

[0008] The spring is fixedly connected to the inner top wall of the protective frame, and the bottom end of the spring is connected to the upper abutment plate for fixing the rangefinder body.

[0009] A threaded tube is embedded in the bottom of the protective frame. The threaded tube is threadedly connected to an adjusting threaded rod, which is rotatably connected to a lower support plate for supporting the rangefinder body via a bearing.

[0010] The bottom of the protective frame is rotatably connected to multiple support components.

[0011] As a preferred embodiment, two limiting rods are welded to the inner top wall and inner bottom wall of the protective frame, and limiting tubes adapted to the limiting rods are welded to the top of the upper abutment plate and the bottom of the lower abutment plate.

[0012] As a preferred implementation, the multiple support components include:

[0013] The hollow panel is rotatably connected to the protective frame via hinges.

[0014] An adjusting plate is located inside the hollow plate, and a counterweight plate is rotatably connected to the side of the adjusting plate.

[0015] As a preferred embodiment, the top of the counterweight plate is provided with a threaded channel, and the threaded channel is threadedly connected to an anchor rod.

[0016] As a preferred embodiment, the hollow plate has a threaded hole on its side, and the threaded hole is threadedly connected to a threaded rod for fixing the adjusting plate.

[0017] As a preferred embodiment, an auxiliary block is welded to the outer periphery of the hollow plate, and a threaded storage tube adapted to the anchor rod is welded to the side of the auxiliary block.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0020] This building rangefinder benefits from the design of a protective frame and two movable plates. The combination of the protective frame and the two movable plates can achieve box-like protection for the rangefinder body. When the two movable plates are opened, one of them does not affect the use of the tester, while the other allows the user to easily reach into the protective frame from that point to operate the buttons on the fixed tester, meeting different testing needs. Compared with the traditional fully enclosed protective design, it can meet the needs of adjustment operation.

[0021] This building rangefinder benefits from the design of the adjusting screw rod and spring. The rotation of the adjusting screw rod can change the position of the lower support plate. The lower support plate, together with the upper support plate, can fix the rangefinder body of various sizes. The spring design provides a certain degree of protection when the whole is moved and carried.

[0022] The rangefinder used in this building construction benefits from the design of the support components. The four support components are tilted and then anchored into the ground to ensure overall stability. In addition, by adjusting the tilt angle of the hollow board and adjusting the extension of the board, it can adapt to the fixing needs of various terrains.

[0023] The rangefinder used in this building can not only provide shielding and protection, but also be opened so that a hand can be reached inside to operate the buttons. Attached Figure Description
