Description

Technical Field

[0001] The utility model relates to the technical field of concrete treatment, in particular to a handheld concrete vibrating device. Background Art

[0002] At present, when construction workers pour concrete for a conventional structural column, in order to compact the concrete, a vibrating rod is used in accordance with the requirements of the construction specification. And the conventional concrete vibrating rod needs to be inserted into the freshly poured concrete to play its role. Moreover, in order to ensure that the vibrating plate can be placed and prevent concrete leakage, there must be an upward opening in the concrete pouring area.

[0003] And these usage requirements for the concrete vibrating rod lead to the following situation: when pouring concrete for some structural columns at the top inside a building and only having a pouring opening on the side, it is very restricted to use the vibrating rod. In this regard, in order to ensure the dense pouring of concrete, on-site construction workers can only install a formwork on the side of the structural column and then hold a steel pipe or a hammer to hammer the formwork by hand. Limited by manpower, this manual vibration is actually very laborious, and the vibration efficiency is extremely low, and at the same time, the vibration effect is not stable. Content of the Utility Model

[0004] The utility model provides a handheld concrete vibrating device. By pressing the vibrating plate against the formwork, the vibration of the electric hammer can be transmitted to the formwork through the vibrating plate and further transmitted to the concrete, so as to quickly compact the concrete, realizing the construction operation of vibrating the concrete without having to extend into the concrete, and solving the above technical problems.

[0005] The technical solution adopted by the utility model to solve the above problems is: to provide a handheld concrete vibrating device, including an electric hammer, a connecting rod, and a vibrating plate. One end of the connecting rod is inserted into the output end of the electric hammer. A sleeve is provided on one side of the vibrating plate, and the other end of the connecting rod is correspondingly inserted into the sleeve to connect the vibrating plate. An insertion limiting groove is also opened on the sleeve, and an insertion limiting member is arranged at the other end of the connecting rod. When the connecting rod is inserted into the sleeve, the insertion limiting member is inserted into the insertion limiting groove to limit the insertion connection between the connecting rod and the vibrating plate.

[0006] Furthermore, a cushion layer is also provided on one side of the vibrating plate.

[0007] Furthermore, the cushion layer is a rigid plastic plate.

[0008] Furthermore, the insertion limiting member is radially movably arranged on the connecting rod; the insertion limiting member moves to insert into the insertion limiting groove or moves to withdraw from the insertion limiting groove to facilitate the separation of the vibrating plate from the connecting rod.

[0009] Further, the other end of the connecting rod is internally hollow, and one end of the inserted limiting member extends into the internal cavity of the connecting rod; meanwhile, an elastic member for pushing the inserted limiting member to extend outwards is further arranged in the internal cavity of the connecting rod.

[0010] Further, one end of the elastic member is fixed to the inner cavity wall of the connecting rod, and the other end is fixedly connected to the inserted end of the inserted limiting member, and the elastic member is always in an elastically compressed state when arranged in the internal cavity of the connecting rod.

[0011] Further, the diameter of the elastic member is larger than the diameter of the through hole on the vibrating rod for the inserted limiting member to movably insert, so that the elastic member cannot pass through the through hole, thereby ensuring that the elastic member is always in an elastically compressed state in the internal cavity of the connecting rod.

[0012] Further, the other end of the inserted limiting member inserted into the inserted limiting groove is an arc surface; moreover, along the axial direction of the connecting rod, both sides of the arc surface are lower than the middle.

[0013] Further, the electric hammer is a wireless electric hammer.

[0014] Further, along the axial direction of the connecting rod, the axial width of the inserted limiting groove is larger than the maximum axial width of the inserted limiting member; moreover, the diameter of the sleeve is also larger than the diameter of the connecting rod.

[0015] Advantages of the utility model:

[0016] A handheld concrete vibrating device of the utility model, on-site construction workers can hold the device and press the device against the formwork on the outer side of the structural column to realize the operation of vibrating the concrete of the structural column from the outside, and this operation is relatively simple and convenient. Moreover, through this device, construction workers can vibrate the concrete in areas where traditional vibrating rods are inconvenient or even unable to reach during on-site construction, so that the concrete in this part of the area is poured densely, ensuring its structural strength.

[0017] In addition, in the face of different sizes of vibrating operation spaces, the vibrating plate can also be replaced according to requirements with a plate body having a shape that can fit the formwork and corresponding dimensions that can most improve the vibrating efficiency, so as to effectively improve the vibrating efficiency and reduce the operation difficulty.

In these drawings, like reference numerals are used to represent like elements. The drawings in the following description are some embodiments of the present utility model, not all embodiments. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0019] Figure 1 is a schematic diagram of the overall structure of the handheld concrete vibrating device for this embodiment;

[0020] Figure 2 is Figure 1 an enlarged view of the partial structure at A in

[0022] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may accordingly change depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0023] Please refer to Figure 1 and Figure 2 , a handheld concrete vibrating device according to a specific embodiment of the present utility model, includes an electric hammer 1, a vibrating rod 2, and a vibrating plate 3. The electric hammer 1 is a common cordless electric hammer on the market, using a built-in battery with a single working duration of about 20 minutes. The vibrating rod 2 is a metal rod, which can be obtained by modifying a drill bit. The left end of the vibrating rod 2 is inserted into the insertion end of the electric hammer 1, and the vibrating plate 3 is installed at the right end of the vibrating rod 2. Correspondingly, the construction worker can hold the electric hammer 1 and press the vibrating plate 3 against the formwork on the outer side of the structural column, and then turn on the electric hammer 1 to transfer the vibration to the formwork and vibrate the concrete inside the formwork, making the concrete vibrate densely to ensure that there are no voids after the structural column is formed.

[0024] Furthermore, in this embodiment, a sleeve 4 is integrally and laterally provided on the left side of the vibrating plate 3, and the right end of the vibrating rod 2 is correspondingly inserted into the sleeve 4 to connect the vibrating plate 3; in this regard, when the construction workers normally operate the electric hammer 1 and press the vibrating plate 3 against the formwork, due to the presence of the sleeve 4, the vibrating plate 3 can be limited in all directions and will not fall off. However, when the construction workers replace the battery of the electric hammer 1 or take a short break, the electric hammer 1 does not work at this time, and the vibrating plate 3 is not pressed against the formwork. The sleeve 4 structure alone cannot prevent the vibrating plate 3 from separating from the vibrating rod 2. In order to avoid the workers repeatedly installing the vibrating plate 3 on the right end of the vibrating rod 2, the sleeve 4 is provided with plug-in limit grooves 5 at the upper and lower positions of the wall, and the upper and lower sides of the vibrating rod 2 are correspondingly provided with plug-in limit members 6; correspondingly, when the workers insert the vibrating rod 2 into the sleeve 4, the plug-in limit member 6 can also be inserted into the plug-in limit groove 5 at the same time, so that the vibrating rod 2 remains inserted into the sleeve 4 and does not fall off, thereby making it difficult for the vibrating plate 3 to separate from the vibrating rod 2, thereby reducing the amount of work for the workers.

[0025] In this embodiment, when the vibrating rod 2 is inserted into the sleeve 4, in order to make the plug-in limit piece 6 correspondingly and exactly inserted into the plug-in limit groove 5, and to make the plug-in limit piece 6 also withdraw from the plug-in limit groove 5 under the action of external force, so as to facilitate the replacement of vibrating plates 3 of other shapes, a plug-in limit groove 5 is also provided on the sleeve 4, and the left end of the vibrating rod 2 is hollow inside, and two plug-in limit pieces 6 are respectively vertically movably plugged in the upper and lower sides of the left end of the vibrating rod 2, and one end of the two plug-in limit pieces 6 extends into the internal cavity of the left end of the vibrating rod 2, and an elastic piece 8 is provided between the end of the two plug-in limit pieces 6 extending into the cavity and the inner wall of the cavity of the vibrating rod 2.

[0026] In this regard, in the present embodiment, the elastic member 8 is always in an elastically compressed state when it is arranged in the cavity, and the elastic member 8 in the compressed state will correspondingly push the corresponding plug-in limiting member 6 to extend outward, so that when the left end of the vibrating rod 2 is inserted into the sleeve 4, the plug-in limiting member 6 is automatically extended and inserted into the plug-in limiting groove 5 under the elastic force of the elastic member 8, so as to limit the vibrating rod 2 from being separated from the sleeve 4. In addition, when it is necessary to insert the vibrating rod 2 into the sleeve 4 or to pull the vibrating rod 2 out of the sleeve 4, the construction worker can also press the plug-in limiting member 6 with force, so that the plug-in limiting member 6 retracts toward the center of the vibrating rod 2 to be hidden in the vibrating rod 2 and is separated from the plug-in limiting groove 5, so as to release the mutual limiting state between the vibrating rod 2 and the sleeve 4, so as to facilitate the replacement of the vibrating plate 3.

[0027] In addition, in order to facilitate the insertion of the vibrating rod 2 into the sleeve 4, and in order to allow the construction workers to insert the vibrating rod 2 into the sleeve 4 without directly pressing the plug-in limiter 6, the plug-in limiter 6 is configured as a plate; Figure 2Taking the plug-in limiting member 6 set upward as an example, the upper end of the plug-in limiting member 6 is an arc edge, and along the axial direction of the vibrating rod 2, the left and right sides of the plug-in limiting member 6 are lower than the middle part thereof. Therefore, when the construction worker inserts the vibrating rod 2 into the sleeve 4, due to the arc-shaped upper edge serving as an arc transition, the plug-in limiting member 6 can automatically retract into the vibrating rod 2 under the pressure of the sleeve wall of the sleeve 4 until the vibrating rod 2 is inserted in place, and when the plug-in limiting member 6 is exactly aligned with the plug-in limiting groove 5, the plug-in limiting member 6 will correspondingly extend into the plug-in limiting groove 5 under the elastic thrust of the elastic member 8, so that the vibrating rod 2 and the sleeve 4 are mutually limited and plugged together, and the vibrating plate 3 will not be easily separated from the vibrating rod 2.

[0028] Furthermore, in order to ensure that the elastic member 8 can always maintain an elastically compressed state in the cavity at the right end of the vibrating rod 2 and prevent the plug-in limiting member 6 from completely falling off the vibrating rod 2 under the elastic force of the elastic member 8, when the plug-in limiting member 6 is set as a plate body, the width of the strip-shaped through hole corresponding to the plug-in limiting member 6 for movable insertion at the right end of the vibrating rod 2 is smaller than the diameter of the elastic member 8.

[0029] In other embodiments, the number of the plug-in limiting members 6 can be one or more. In addition to being arranged staggeredly up and down, the two plug-in limiting members 6 above and below can also be symmetrically arranged and share one elastic member 8. In addition, in this embodiment, the elastic member 8 is a spring.

[0030] In addition, in order to avoid damage to the connection structure between the vibrating rod 2 and the vibrating plate 3 caused by the vibration generated during the operation of the electric hammer 1, along the axial direction of the vibrating rod 2, the axial width of the plug-in limiting groove 5 is greater than the maximum axial width of the plug-in limiting member 6; moreover, the diameter of the sleeve 4 is also greater than the diameter of the vibrating rod 2.

[0031] Furthermore, in order to prevent the vibrating plate 3 from damaging the formwork during vibration, a cushion layer 7 is also attached to the right side of the vibrating plate 3; and in order to avoid the vibration not being effectively transmitted to the concrete inside the formwork due to the cushion layer 7 being too soft, the cushion layer 7 is a plate body formed by a hard plastic material; in this regard, the vibrating plate 3 can form an effective buffer with the formwork through the cushion layer 7, and the vibration of the vibrating plate 3 will not be overly weakened by the cushion layer 7.

[0032] It should be noted that: in other embodiments, in order to enable the cushion layer 7 to serve as a buffer and not overly weaken the vibration force, the cushion layer 7 can also be a plate body made of rubber material or other known materials with a moderate softness and hardness.

[0033] For the parts not mentioned above, the prior art is applicable.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
