Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to an adjustable surveying device for easy building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project, encompassing the building process for various types of structures. Exterior walls may involve plastering, insulation, painting, and curtain wall installation; interior walls involve plastering, puttying, wallpapering, or painting with latex paint, emphasizing the adhesion, surface smoothness, and aesthetics of the decorative layer. A laser level is a measuring instrument that uses a laser beam to provide a horizontal or vertical baseline, widely used in construction, decoration, and surveying.

[0003] In interior wall decoration within the construction industry, laser levels are essential for measuring and mapping walls and floors. Precise baseline measurements using a laser beam ensure accurate construction. However, existing laser levels require positioning during use to prevent collisions that could shift the laser beam's position. Current devices rely on clamping and friction for positioning, resulting in poor stability. Therefore, we propose an adjustable mapping device for convenient use in construction. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an adjustable surveying device that is convenient for building construction, so as to solve the technical problems of current equipment clamping and fixing, friction affecting the fixing strength and poor stability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable surveying device for easy construction, including a rear frame and a fixed base. The fixed base has an assembly opening, and an airbag is installed in the assembly opening. Side wing plates are slidably installed at the openings on both sides of the fixed base. Side strips are fixed at the side openings of the fixed base, and synchronizing rods are slidably installed at the front ends of the two side strips. A piston rod is slidably installed in the inner cavity of the side strip, and the outer end of the piston rod is fixed to the synchronizing rod. A battery box is provided on the front side of the rear frame, and the battery box is inserted into the rear opening of the laser level. A movable plate is provided at the lower end of the rear frame, and the lower end of the movable plate is connected to the fixed base.

[0006] In use, the battery box of this utility model is inserted into the compartment at the rear of the laser level to provide power. When placed on the ground, the side wing plates unfold to increase the support surface. When fixed to a wall or door, the tightening bolts are loosened by rotating them, and then the movable plate is deflected 90 degrees to adjust the position of the fixing seat, facilitating wall fixing and keeping the laser level parallel to the wall. Through the above structural design, the device can be easily adjusted for fixing angles, and can be operated according to actual installation needs, improving practicality. When fixing the fixing seat, first pull the synchronous rod outward to synchronously drive the movable plate. The piston rod drives the linkage rod to slide and close, causing the side wing plate to retract inward. After the side wing plate passes through the side opening of the fixed seat, it squeezes the airbag. The gas in the airbag is discharged through the vacuum suction cup. After the fixed seat is pressed against the smooth fixed surface, the synchronous rod is released and reset by the spring. At this time, the side wing plate unfolds outward, synchronously pulling the airbag to extend outward. At this time, the cavity inside the airbag increases, causing the air pressure to decrease and generating a high-intensity negative pressure. Through the above structural design, the device uses a press-type structural design to facilitate the adsorption fixation of the connection parts, effectively improving the connection strength while reducing the difficulty of operation.

[0007] Preferably, the side wing plate is L-shaped, and the lower end plane of the side wing plate is at the same height as the bottom of the fixing base, and the inner end of the side wing plate is connected and fixed to the airbag.

[0008] Preferably, both ends of the outer side of the edge strip are provided with side openings, and a linkage rod is provided in the side opening. The two ends of the linkage rod are respectively rotatably mounted on the side wing plate and the piston rod by hinges.

[0009] Preferably, a spring is sleeved at the front end of the piston rod, and the two ends of the spring are fixed to the top of the side strip and the synchronizing rod, respectively. A vacuum suction cup is fixed in the bottom recess of the fixing seat, and the vacuum suction cup is connected to the air bag through a conduit.

[0010] Preferably, the lower end of the rear frame is provided with a connecting groove, the upper end of the movable plate is rotatably installed inside the connecting groove, and a clamping bolt is threaded on the lower rear end of the rear frame.

[0011] Preferably, the threaded portion of the clamping bolt passes through the movable plate and is threadedly installed in the connecting groove, and the clamping surface of the clamping bolt is in contact with the surface pressure port of the movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a rear-mounted frame with a battery box inserted into the compartment at the rear of the laser level for power supply. When placed on the ground, the side panels unfold to increase the support surface. When fixed to a wall or door, the tightening bolts are loosened by rotating the frame, and the movable plate is rotated 90 degrees to adjust the position of the fixing seat, facilitating wall fixation and ensuring the laser level remains parallel to the wall. This structural design allows for easy adjustment of the fixing angle, enabling operation according to actual installation needs and improving practicality.

[0013] 2. This utility model also incorporates a fixed base design. When the fixed base is in place, the synchronous rod is pulled outward to synchronously drive the piston rod. The piston rod drives the linkage rod to slide and close, causing the side wing plate to retract inward. After the side wing plate passes through the side opening of the fixed base, it compresses the airbag. The gas inside the airbag is discharged through the vacuum suction cup. After the fixed base is pressed against the smooth fixing surface, the synchronous rod is released and the spring returns to its original position. At this time, the side wing plate unfolds outward, synchronously pulling the airbag outward. The increased cavity inside the airbag reduces the air pressure, generating a high-intensity negative pressure. Through the above structural design, this device, with its press-type structural design, facilitates the adsorption-type fixing of the connection parts, effectively improving the connection strength while reducing the difficulty of operation.
