Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a tool for controlling the flatness of concrete floors. Background Technology

[0002] An electric pick is a double-insulated handheld power tool powered by a single-phase series motor. It is safe, reliable, efficient, and easy to operate, and is widely used in the construction and home decoration industries.

[0003] An electric hammer mainly consists of an electric motor, a gear reducer, a crank-connecting rod impact structure, a working tool, a power switch, and power connection components. The working principle of an electric hammer is that the electric motor drives the crank-connecting rod impact structure, causing the working tool to reciprocate, thereby enabling operations such as breaking, leveling, and excavating materials such as concrete, bricks, and brick walls.

[0004] Currently, existing electric picks (such as patent number: CN214352209U) disclose an electric pick. This invention improves the problem that children or animals may accidentally touch the switch, which may cause harm to personal safety. This application has an anti-touch bracket installed on the electric pick, so that the switch button is not easily accidentally touched and turned on when not in use, thus improving the safety of the electric pick.

[0005] However, during the implementation of the above technical solutions, at least the following technical problems were found: In use, the existing handheld electric picks have pointed tips. When the pointed handheld electric picks are inserted into concrete, they mainly break the concrete through point impact force from the pointed tip. This point breaking method will cause the concrete surface to be broken into small, uneven pieces. During the leveling process, it is difficult to control the flatness of the entire surface through the pointed tip. This requires high skill from the technicians and is inconvenient to operate. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a tool for controlling the flatness of concrete floors. It solves the problem that existing handheld electric picks have pointed tips. When these picks are inserted into concrete, they mainly break the concrete through point-like impact force at the tip. This point-like breaking method results in the concrete surface being broken into uneven small pieces. During the leveling process, it is difficult to control the flatness of the entire surface using the pointed tip. This also poses a technical problem that requires highly skilled technicians and is inconvenient to operate.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A tool for controlling the flatness of a concrete floor includes a handheld electric pick. The handheld electric pick has a horizontal plate mechanism for leveling the concrete slab. The horizontal plate mechanism includes a shovel plate, and a mounting rod is fixedly installed on the side end of the shovel plate. The shovel plate is made of metal and has a thickness of five millimeters. The side end of the handheld electric pick has a mounting connector. The inner side wall of the mounting connector has two mounting grooves. Four limiting plates are fixedly installed on the side end of the mounting connector, with each pair of limiting plates forming a group. The upper end of each component has a first circular groove. A side plate is fixedly installed on the side end of the mounting connector. A threaded rod is rotatably installed on the upper end of the side plate. Two uprights are fixedly installed on the upper end of the side plate. A pressure plate is provided on the upper end of the side plate. Two locking rods are fixedly installed on the lower end of the pressure plate. A threaded groove is opened through the upper end of the pressure plate. The threaded rod is rotatably installed on the inner side wall of the threaded groove. Two second circular grooves are opened through the upper end of the pressure plate. The two uprights are slidably installed on the inner side wall of the second circular grooves.

[0011] Preferably, two rectangular slide bars are fixedly installed at the circumferential end of the mounting rod, and positioning blocks are fixedly installed at the side ends of the two rectangular slide bars.

[0012] Preferably, the upper ends of the two positioning blocks are provided with locking holes, the two rectangular slide rods are respectively slidably installed on the inner sidewall of the mounting groove, and the locking rod is slidably installed through the inner sidewall of the two first circular grooves and the locking holes.

[0013] (III) Beneficial Effects

[0014] 1. This device sets the end of the handheld electric pick as a flat shovel, changing the pointed tip to a flat tip. Since the contact area of ​​the flat tip is relatively large and more uniform, it is easier to flatten the concrete surface according to the predetermined height and level during operation. Compared with pointed tools, it can cover a larger area more efficiently and leave a smoother surface.

[0015] 2. This device features a locking mechanism that is easy to install and disassemble. The locking rod on the pressure plate engages with the inner wall of the first circular groove and the locking hole to fix the shovel plate, ensuring that the shovel plate can be firmly locked on the handheld electric pick. This provides high stability, reduces the risk of the shovel plate accidentally falling off during operation, and facilitates quick disassembly and maintenance of the shovel plate.

Detailed Implementation

[0022] This application provides a tool for controlling the flatness of concrete floors, effectively solving the problem that existing handheld electric picks 1, with their pointed tips, primarily break concrete through point-like impact when inserted into it. This point-like breaking method results in the concrete surface being broken into uneven small pieces, making it difficult to control the flatness of the entire surface during leveling. This also presents technical challenges due to the high skill requirements and inconvenience of operation. This device addresses these issues by setting the end of the handheld electric pick 1 as a flat shovel 4, replacing the pointed tip with a flat one. Since the flat tip has a relatively larger and more uniform contact area, it is easier to level the concrete surface to a predetermined height and levelness during operation. Compared to pointed tools, it can more efficiently cover a larger area and leave a smoother surface.

[0023] Example

[0024] The technical solution in this application embodiment effectively solves the problem that existing handheld electric picks 1, with their pointed ends, primarily break concrete through point-like impact when inserted into it. This point-like breaking method results in the concrete surface being broken into uneven small pieces. During leveling, it is difficult to control the flatness of the entire surface using only the pointed end, requiring highly skilled technicians and causing operational inconvenience. The overall approach is as follows: A tool for controlling the flatness of a concrete floor surface, comprising a handheld electric pick 1, with a horizontal plate mechanism on the handheld electric pick 1 to facilitate leveling of the concrete floor slab. The horizontal plate mechanism includes a shovel... The flat plate 4 has a mounting rod 41 fixedly installed on its side end. The flat plate 4 is made of metal and has a thickness of five millimeters. When in use, this device can drive the handheld electric pick 1. After the handheld electric pick 1 is started, it will cause the flat plate 4 to vibrate. The user can control the handheld electric pick 1 to move the flat plate 4 to the position to be flattened and flatten the concrete floor slab. This device replaces the pointed head on the ordinary handheld electric pick 1 with the flat plate 4, which effectively reduces the destructiveness of the handheld electric pick 1. By using the optimized handheld electric pick 1 to flatten the concrete floor surface to be treated, the flatness of the concrete floor surface is effectively improved and the overall appearance quality is effectively improved.

[0025] The side end of the handheld electric pick 1 is provided with a mounting connector 2. The inner side wall of the mounting connector 2 has two mounting grooves 21. Four limiting plates 22 are fixedly installed on the side end of the mounting connector 2. The limiting plates 22 are in pairs. The upper end of each pair of limiting plates 22 is provided with a first circular groove 23. The side end of the mounting connector 2 is fixedly installed with a side plate 24. The upper end of the side plate 24 is rotatably installed with a threaded rod 26. The upper end of the side plate 24 is fixedly installed with two uprights 25. The upper end of the side plate 24 is provided with a pressure plate 3. The lower end of the pressure plate 3 is fixedly installed with two locking rods 31. The upper end of the pressure plate 3 is provided with a threaded groove 33. The threaded rod 26 is rotatably installed on the inner side wall of the threaded groove 33. When using, the force of the handheld electric pick 1 can be controlled according to the flatness of the floor to adjust the flatness of the floor. When it is necessary to disassemble or assemble the scraper plate 4, the user can rotate the threaded rod 26. The rotation of the threaded rod 26 drives the pressure plate 3 to move upward.

[0026] Two second circular grooves 32 are formed through the upper end of the pressure plate 3. Two uprights 25 are slidably installed on the inner sidewalls of the second circular grooves 32. Two rectangular sliding rods 42 are fixedly installed on the circumferential end of the mounting rod 41. Positioning blocks 43 are fixedly installed on the side ends of the two rectangular sliding rods 42. Locking holes 44 are formed through the upper ends of the two positioning blocks 43. The two rectangular sliding rods 42 are slidably installed on the inner sidewalls of the mounting groove 21. Locking rod 31 is slidably installed through the inner sidewalls of the two first circular grooves 23 and the locking holes 44. The pressure plate 3 moves upward and gradually moves away from the inner sidewalls of the first circular grooves 23 and the locking holes 44. After the locking rod 31 slides away from the inner sidewall of the locking holes 44, the user can pull out the shovel plate 4 to drive the rectangular sliding rods 42 on the mounting rod 41 out of the mounting groove 21. The disassembly and assembly are convenient.

[0027] To address the problems existing in the prior art, this utility model provides a tool for controlling the flatness of concrete floors. This device sets the end of the handheld electric pick 1 as a flat shovel 4, changing the pointed tip to a flat tip. Since the contact area of ​​the flat tip is relatively large and more uniform, it is easier to flatten the concrete surface according to the predetermined height and level during operation. Compared with pointed tools, it can cover a larger area more efficiently and leave a relatively flat surface.

[0028] Working principle:

[0029] When in use, this device drives a handheld electric pick 1. Once activated, the handheld electric pick 1 causes the scraper plate 4 to vibrate. The user can control the handheld electric pick 1 to move the scraper plate 4 to the position to be leveled, thus leveling the concrete slab. This device replaces the pointed tip of a regular handheld electric pick 1 with the scraper plate 4, effectively reducing the destructive power of the handheld electric pick 1. By using the optimized handheld electric pick 1 to level the concrete surface, the flatness of the concrete surface is effectively improved, and the overall appearance quality is significantly enhanced. During use, the flatness of the concrete slab is adjusted according to the desired levelness. The user can control the force of the handheld electric pick 1 to smooth the floor surface. When it is necessary to disassemble or assemble the pick plate 4, the user can rotate the threaded rod 26. The rotation of the threaded rod 26 drives the pressure plate 3 to move upward. The pressure plate 3 moves upward and gradually moves away from the inner wall of the first circular groove 23 and the locking hole 44. After the locking rod 31 slides away from the inner wall of the locking hole 44, the user can pull out the pick plate 4 and drive the rectangular sliding rod 42 on the mounting rod 41 out of the mounting groove 21. Disassembly and assembly are convenient. In the current handheld electric pick 1, the end is pointed. When a pointed-end handheld electric pick 1 is inserted into concrete, it primarily breaks the concrete through point-like impact force from its tip. This point-like breaking method results in the concrete surface being broken into uneven small pieces. During the leveling process, it is difficult to control the flatness of the entire surface using the pointed end, requiring highly skilled technicians and being inconvenient to operate. This device, by setting the end of the handheld electric pick 1 as a flat shovel 4, replaces the pointed tip with a flat one. Since the contact area of ​​the flat one is relatively large and more uniform, it is easier to level the concrete surface according to the predetermined height and levelness during operation. Compared with pointed tools, it can cover a larger area more efficiently and leave a relatively flat surface. Furthermore, this device is equipped with a locking mechanism that is easy to disassemble and assemble. The locking rod 31 on the pressure plate 3 is engaged with the inner wall of the first circular groove 23 and the locking hole 44 to fix the flat shovel 4, ensuring that the flat shovel 4 can be firmly locked onto the handheld electric pick 1. This provides high stability, reduces the risk of the flat shovel 4 accidentally falling off during operation, and facilitates quick disassembly and maintenance of the flat shovel 4.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
