Description

Technical Field

[0001] This utility model relates to the field of concrete construction equipment technology, and in particular to a concrete leveling device for concrete pouring. Background Technology

[0002] In construction engineering, concrete pouring is a crucial step, and the subsequent leveling directly impacts the quality of the concrete surface. Currently, a long handle connected to a horizontal plate is typically used to level the concrete surface. However, the handle length is usually fixed, making it inconvenient to carry and store due to its length. Furthermore, the fixed handle length may not meet the needs of different operators and construction scenarios. In addition, the horizontal plate of existing leveling devices is mostly fixed and cannot be folded. In confined spaces, the large horizontal plate is difficult to maneuver, while in open areas, the fixed size may result in low leveling efficiency. Therefore, there is an urgent need for a concrete leveling device with an adjustable handle length for easy storage and use, and a foldable horizontal plate that can be flexibly used in both confined and open spaces. Utility Model Content

[0003] The main objective of this invention is to provide a concrete leveling device for concrete pouring, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a concrete leveling device for concrete pouring, including a leveling mechanism, wherein a telescopic mechanism is rotatably connected to the middle of the leveling mechanism, and a handle is provided at the upper end of the telescopic mechanism;

[0005] The telescopic mechanism includes an outer limiting sleeve, a knob, a groove, a hexagonal bolt post, a threaded rod, and an internally threaded tube. The lower end of the internally threaded tube is rotatably connected to one side of the middle of the main board. The lower part of the outer limiting sleeve is slidably connected to the outer circumference of the internally threaded tube. The lower part of the knob is rotatably connected to the upper end of the outer limiting sleeve through damping. The upper end of the threaded rod is fixedly connected to the middle of the knob. The lower part of the threaded rod is threadedly connected to the middle of the internally threaded tube. The groove is formed in the middle of the upper side of the knob. The lower end of the hexagonal bolt post is fixedly connected to the bottom wall of the groove. One end of the handle is fixedly connected to the left and right sides of the upper part of the outer limiting sleeve.

[0006] Preferably, a bellows cover is fixedly connected to the lower part of the outer limiting sleeve. The bellows cover is sleeved on the outer periphery of the outer limiting sleeve and the inner threaded tube, and the lower part of the bellows cover is fixedly connected to the bottom of the inner threaded tube.

[0007] Preferably, a rubber shock-absorbing sleeve is provided on the outer periphery of the handle.

[0008] Preferably, the flattening mechanism includes a main board, a connecting component, and a sub-board. One end of the sub-board is rotatably connected to the left and right sides of the main board via a hinge, and the main board and the sub-board are connected in the middle via the connecting component.

[0009] Preferably, a bracket is fixedly connected to the other side of the middle part of the motherboard, a vibration motor is provided on the upper part of the bracket, and a power controller is installed on the upper part of the outer limiting sleeve. The power controller and the vibration motor are electrically connected.

[0010] Preferably, the connecting assembly includes a fixed base, a plug rod, a connecting base, a spring, a pull ring, and a retaining ring. The lower part of the connecting base is fixedly connected to the left and right sides of the main board, and the lower part of the fixed base is fixedly connected to the end of the sub-board near the main board. One end of the plug rod is slidably connected to the upper part of the fixed base, and the other end of the plug rod is disposed inside the connecting base. The middle part of the retaining ring is fixedly connected to the middle part of the plug rod. The spring is sleeved on the outer periphery of the plug rod and is disposed between the fixed base and the retaining ring. The pull ring is fixedly connected to the end of the plug rod away from the connecting base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When the length of the telescopic mechanism needs to be adjusted, rotate the knob or use an electric wrench to rotate the hexagonal bolt post, which in turn rotates the threaded rod. Since the outer limit sleeve and the inner threaded tube restrict each other's rotation, the threaded rod causes the outer limit sleeve to move relative to the inner threaded tube, thereby adjusting the length of the telescopic mechanism for easy storage or use.

[0013] By pulling the ring, the insert rod moves the retaining ring, which in turn compresses the spring, causing the end of the insert rod to disengage from the connector. This allows the sub-plate to be folded relative to the main plate, thus changing the length of the horizontal plate and enabling it to be used in different environments. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a concrete leveling device for concrete pouring includes a leveling mechanism 2, a telescopic mechanism 1 rotatably connected to the middle of the leveling mechanism 2, and a handle 6 provided at the upper end of the telescopic mechanism 1.

[0021] In this embodiment, the telescopic mechanism 1 includes an outer limiting sleeve 101, a knob 102, a groove 103, a hexagonal bolt post 104, a threaded rod 105, and an internally threaded tube 106. The lower end of the internally threaded tube 106 is rotatably connected to one side of the middle portion of the main board 201. The lower part of the outer limiting sleeve 101 is slidably connected to the outer periphery of the internally threaded tube 106. The lower part of the knob 102 is rotatably connected to the upper end of the outer limiting sleeve 101 through damping. The upper end of the threaded rod 105 is fixedly connected to the middle portion of the knob 102. The lower part of the threaded rod 105 is threadedly connected to the middle portion of the internally threaded tube 106. The groove 103 is formed in the middle of the upper side of the knob 102. The lower end of the bolt 104 is fixedly connected to the bottom wall of the groove 103. One end of the handle 6 is fixedly connected to the upper left and right sides of the outer limiting sleeve 101. A bellows cover is fixedly connected to the lower part of the outer limiting sleeve 101. The bellows cover is fitted around the outer periphery of the outer limiting sleeve 101 and the internal threaded tube 106. The lower part of the bellows cover is fixedly connected to the bottom of the internal threaded tube 106. A rubber shock-absorbing sleeve 7 is provided around the outer periphery of the handle 6. A bracket 3 is fixedly connected to the other side of the middle part of the main board 201. A vibration motor 4 is provided on the upper part of the bracket 3. A power controller 5 is installed in the upper part of the outer limiting sleeve 101. The power controller 5 and the vibration motor 4 are electrically connected.

[0022] Specifically, when it is necessary to adjust the length of the telescopic mechanism 1, rotate the knob 102, or use an electric wrench to drive the hexagonal bolt post 104 to rotate, thereby causing the threaded rod 105 to rotate. Since the outer limiting sleeve 101 and the inner threaded tube 106 restrict each other's rotation, the threaded rod 105 drives the outer limiting sleeve 101 to move relative to the inner threaded tube 106, thereby adjusting the length of the telescopic mechanism 1 for easy storage or use.

[0023] In this embodiment, the leveling mechanism 2 includes a main board 201, a connecting component 202, and a secondary board 203. One end of the secondary board 203 is rotatably connected to the left and right sides of the main board 201 via a hinge. The main board 201 and the secondary board 203 are connected in the middle via the connecting component 202. The connecting component 202 includes a fixing seat 2021, a plug rod 2022, a connecting seat 2023, a spring 2024, a pull ring 2025, and a retaining ring. The lower part of the connecting seat 2023 is fixedly connected to the left and right sides of the main board 201. The lower part of the fixed seat 2021 is fixedly connected to the end of the sub-plate 203 near the main plate 201. One end of the insertion rod 2022 is slidably connected to the upper part of the fixed seat 2021. The other end of the insertion rod 2022 is located inside the connecting seat 2023. The middle part of the retaining ring is fixedly connected to the middle part of the insertion rod 2022. The spring 2024 is sleeved on the outer circumference of the insertion rod 2022 and is located between the fixed seat 2021 and the retaining ring. The pull ring 2025 is fixedly connected to the end of the insertion rod 2022 away from the connecting seat 2023.

[0024] Specifically, by pulling the pull ring 2025, the insert rod 2022 moves the retaining ring, which in turn compresses the retaining ring 2024, causing the end of the insert rod 2022 to disengage from the connecting seat 2023. This allows the sub-plate 203 to be folded relative to the main plate 201, thereby changing the length of the horizontal plate and enabling it to be used in different environments.

[0025] Working principle:

[0026] When the length of the telescopic mechanism 1 needs to be adjusted, rotate the knob 102, or use an electric wrench to rotate the hexagonal bolt post 104, which in turn causes the threaded rod 105 to rotate. Since the outer limiting sleeve 101 and the inner threaded tube 106 restrict each other's rotation, the threaded rod 105 causes the outer limiting sleeve 101 to move relative to the inner threaded tube 106, thereby adjusting the length of the telescopic mechanism 1 for easy storage or use. By pulling the pull ring 2025, the insertion rod 2022 causes the retaining ring to move, which in turn causes the retaining ring to compress the spring 2024, thereby causing the end of the insertion rod 2022 to disengage from the connecting seat 2023, so that the sub-plate 203 can be folded relative to the main plate 201, thereby changing the length of the horizontal plate, so that it can be used in different environments.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
