Description

Technical Field

[0001] This utility model relates to the field of steel frame construction technology, and more specifically, to a level instrument for steel frame construction. Background Technology

[0002] A level is an instrument used to measure the elevation difference between two points. It obtains the horizontal line of sight by centering the bubble in the level tube or by using an electronic sensor to determine the elevation of a point on the ground. It is widely used in engineering construction, topographic mapping, geological exploration and other fields, and is a core tool for elevation measurement.

[0003] For example, Chinese patent CN220268884U discloses an engineering construction level, including a support sleeve. A tripod is installed on the outer wall of the support sleeve near the bottom. A mounting plate is fixedly connected to the top outer wall of a threaded rod. A protective box is fixedly connected to the outer wall of the mounting plate on the side away from the threaded rod. Two raised sliders are fixedly connected to the inner walls of both sides of the protective box. A lifting plate is slidably connected to the outer walls of multiple raised sliders. An adjustment component for adjusting the height of the lifting plate is installed inside the protective box. In this utility model, by setting up the protective box, raised sliders, lifting plate, and adjustment component, when it is necessary to move the level body, the lifting plate can be quickly lowered to drive the level body into the interior of the protective box and close the box door. The protective box and the box door can effectively protect the level body and effectively avoid collisions during the movement of the level body, thereby effectively reducing the damage to the level body during the transfer process.

[0004] The aforementioned patent has the following problems: The patented device has some drawbacks in its use. For example, when using the device, workers need to unlock the cabinet door first, then open it, and then turn the handle to remove the level instrument. This process is cumbersome and time-consuming, especially in scenarios with frequent use, where it is inefficient. Therefore, we propose a level instrument for steel frame construction. Summary of the Invention

[0005] The purpose of this invention is to provide a level instrument for steel frame construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A leveling instrument for steel frame construction includes a support frame, a housing, and the instrument body, and further includes: Two fixed blocks are fixedly installed on the housing, which is fixedly installed on the top of the bracket. A spirit level is inserted between the two fixed blocks. Each of the two fixed blocks has a sliding groove, and a sliding block is slidably installed in each of the two sliding grooves. Both sliding blocks are located on top of the spirit level. Two sealing plates are rotatably mounted on the top of the housing, and a sliding plate is slidably mounted inside the housing. The level body is fixedly mounted on the top of the sliding plate. Two sets of driving components are located in two fixed blocks respectively, and are used to drive the two sliding blocks to slide. A power assembly, located within the housing, is used to drive the sliding plate to slide and the two sealing plates to rotate.

[0007] In this technical solution, when the level instrument body needs to be used, the set power component can drive the sliding block to slide upward, the sliding block drives the level instrument body to move upward, and the set power component can drive the two sealing plates to rotate upward. After the two sealing plates rotate 180°, the level instrument body also rises to a suitable position, which is convenient for using the level instrument body and does not require manual operation by the staff, making it simple and quick. When the bubble level needs to be replaced after prolonged use, the sliding block can be pulled upwards using the set drive component, allowing the bubble level to be removed. Then, the new bubble level is placed between the two fixed blocks, and the sliding block can be pulled downwards using the set drive component. Finally, the two sliding blocks can fix the bubble level, making it easy to replace the corresponding bubble level. The operation is simple and requires no tools.

[0008] As an improvement of this utility model, the driving component includes: A fixed column is fixedly installed in a sliding groove. The upper end of the fixed column passes through a sliding block, and the sliding block is slidably connected to the fixed column. A tension spring is sleeved on the fixed column, and a rotating rod is rotatably installed on the sliding block. The rotating rod is inserted into the sliding groove.

[0009] In this technical solution, when the bubble level needs to be replaced after prolonged use, first pull the rotating rod to cause the sliding block to slide upwards. The sliding block pulls the tension spring to extend. When the sliding block slides to the appropriate position, rotate the rotating rod forward. The rotating rod will insert into the sliding groove, thus fixing the position of the sliding block. At this point, the bubble level can be removed. Place the new bubble level between the two fixed blocks, and then rotate the rotating rod in the opposite direction. The rotating rod will disengage from the sliding groove. Under the tension of the tension spring, the sliding block will slide downwards. Finally, the two sliding blocks can fix the bubble level, making it convenient to replace the corresponding bubble level. The operation is simple and requires no tools.

[0010] As an improvement of this utility model, the power assembly includes: The power chamber is located inside the housing. A motor is fixedly installed inside the power chamber.

A third bevel gear is fixedly installed at both ends of the second bevel gear. A fourth bevel gear is meshed with the tops of both third bevel gears. Two worm gears are fixedly mounted on the tops of two fourth bevel gears. A worm wheel is meshed on one side of each worm gear. One end of each worm wheel passes through the power chamber and is fixedly connected to two sealing plates.

[0011] In this technical solution, when the level instrument body needs to be used, the motor is first started. The motor is powered on and drives the threaded rod to rotate. Under the action of the thread, the threaded rod drives the sliding block to slide upward. The sliding block drives the level instrument body to move upward. At the same time, the threaded rod drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear meshing with it to rotate. The second bevel gear drives two third bevel gears to rotate. The two third bevel gears drive two fourth bevel gears meshing with them to rotate. The two fourth bevel gears drive two worm gears to rotate. The two worm gears drive two worm wheels meshing with them to rotate. The two worm wheels drive two sealing plates to rotate upward. After the two sealing plates rotate 180°, the level instrument body also rises to a suitable position, making it convenient to use. It does not require manual operation by the staff, making it simple and quick.

[0012] As an improvement of this utility model, the bottoms of the two sliding blocks are arc-shaped.

[0013] In this technical solution, it is ensured that the two sliding blocks can fix the spirit level.

[0014] As an improvement of this utility model, sealing rubber gaskets are fixedly installed on the sides of the two sealing plates that are close to each other, and the two sealing rubber gaskets are in close contact.

[0015] In this technical solution, the sealing rubber gasket ensures that the housing can be sealed.

[0016] As an improvement of this utility model, the output shaft, threaded rod, first bevel gear, second bevel gear, two third bevel gears, two fourth bevel gears, two worms, and two worm wheels of the motor are all rotatably connected to the power cavity.

[0019] In this technical solution, the stability of the sliding plate is ensured, and the stability of the level instrument body's lifting and lowering is guaranteed.

[0020] As an improvement of this utility model, the two ends of the tension spring are welded to the sliding block and the inner wall of the sliding groove, respectively.

[0021] This technical solution ensures the stability of the tension spring during use.

[0022] The steel frame construction level instrument of this utility model has the following beneficial effects: 1. The level instrument used in this steel frame construction can be used to move the sliding block upwards via a power component when the instrument body is needed.
