Description

Technical Field

[0001] This utility model relates to the technical field of plastering construction, and more specifically, to a vibratory plastering device. Background Technology

[0002] In the main construction of a building, plastering is one of the most important construction procedures. During the plastering process, plasterboard is one of the commonly used tools for applying and smoothing the mortar.

[0003] However, most existing plasterboards are of a fixed shape, usually straight. In some architectural decoration projects with curved structures, using straight plasterboards makes it difficult to evenly apply the mortar and adhere it to the curved surface. This not only results in low construction efficiency but also makes it difficult to guarantee the quality of plastering, easily leading to problems such as inconsistent mortar thickness and uneven surfaces. This requires a lot of repair work later, increasing construction costs and time.

[0004] In addition, air bubbles are easily generated inside the mortar during the plastering process. If they are not removed in time, they will reduce the density and bonding strength of the mortar, thus affecting the plastering quality.

[0005] In summary, how to effectively perform plastering operations on curved structures and promptly remove air bubbles generated inside the mortar is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a vibratory plastering device that effectively solves the problem that existing plasterboards cannot adapt to construction surfaces with different curvatures, improves the efficiency and quality of plastering construction, and reduces construction costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A vibratory plastering device includes a handle and a flexible plaster shovel. Multiple connecting rods are provided between the handle and the flexible plaster shovel to allow the flexible plaster shovel to bend into a certain arc. A vibration device is provided on the handle to drive the flexible plaster shovel to vibrate.

[0009] Preferably, the two ends of the plurality of connecting rods are respectively hinged to the handle and the flexible ash shovel, and each connecting rod is provided with an adjustment structure to adjust the distance between the handle and the flexible ash shovel at that point.

[0010] Preferably, the adjustment structure includes:

[0011] A groove is formed on the corresponding connecting rod, and the groove extends along the length direction of the connecting rod;

[0012] An adjusting bolt is slidably disposed within the slide groove, and the adjusting bolt is fixed between the slide groove and the handle by a positioning nut.

[0013] Preferably, each of the connecting rods is provided with a hinge at the end opposite to the handle, and the hinge is connected to the non-working surface of the flexible shovel so that the connecting rod is hinged to the flexible shovel.

[0014] Preferably, a buffer pad is provided between each of the hinge members and the flexible ash shovel.

[0015] Preferably, the buffer pad is a rubber buffer pad.

[0016] Preferably, the flexible ash shovel is a rubber ash shovel.

[0017] Preferably, it also includes a switch, wherein a battery is built into the handle, and the switch is electrically connected between the battery and the vibration device.

[0018] Preferably, the vibration device includes a vibration motor, which is mounted on the handle.

[0019] Preferably, it also includes a charging interface, which is disposed on the handle, and a converter is electrically connected between the charging interface and the battery.

[0020] The vibratory plastering device provided by this utility model features a flexible plaster shovel connected to its handle by multiple connecting rods. This allows the flexible shovel to bend into a specific arc shape according to construction needs, adapting to different shaped construction surfaces. Especially when dealing with curved walls or columns, it enables uniform application of mortar, avoiding the low construction efficiency caused by traditional straight plaster shovels failing to conform to curved surfaces. Simultaneously, the vibration device on the handle effectively drives the flexible shovel to vibrate, helping to expel air bubbles from the mortar, improving its density and bonding strength, and further enhancing the plastering quality.

[0021] The further solutions provided in this application can also achieve at least one of the following beneficial technical effects:

[0022] The adjustable structure allows the curvature of the flexible plastering trowel to be flexibly adjusted according to actual construction needs. This design not only improves the adaptability of the plastering tool to surfaces with different curvatures, but also significantly enhances construction efficiency.

[0023] The use of buffer pads effectively reduces rigid contact between the flexible trowel and the connecting rod during adjustment and use, preventing localized deformation or damage to the flexible trowel due to concentrated force transmission, thereby extending the service life of the device. Simultaneously, the buffer pads also enhance the stability of the flexible trowel when adjusting to different curvatures, ensuring surface smoothness and consistent quality during plastering operations.

[0024] The built-in battery design eliminates the limitation of external power sources, improving the portability and applicability of the device, and showing significant advantages, especially in construction environments where power is inconvenient to obtain. Attached Figure Description

This application discloses a vibratory plastering device.

[0035] The core of this utility model is to provide a vibratory plastering device.

[0036] Please refer to Figure 1 .

[0037] The vibratory plastering device provided by this utility model includes a handle 1 and a flexible plaster shovel 2. Multiple connecting rods 3 are provided between the handle 1 and the flexible plaster shovel 2 to allow the flexible plaster shovel 2 to bend into a certain arc (e.g., ...). Figure 4 As shown in the figure, a vibration device is provided on the handle 1, which is used to drive the flexible ash shovel 2 to vibrate.

[0038] Specifically, multiple connecting rods 3 are connected between the handle 1 and the flexible ash shovel 2. In this embodiment, four connecting rods 3 are used. In other embodiments, no less than two connecting rods should be selected and arranged opposite each other on the handle 1. The handle 1 can be in the shape of a bow handle to facilitate the worker's grip. The vibration device can be set on the side surface of the handle 1 or in the installation space opened inside the handle 1.

[0039] Optionally, the surface of the handle 1 can be provided with a flexible sleeve to cushion the vibration generated by the vibration device, improve the operator's hand comfort, and reduce hand fatigue during prolonged use. The flexible sleeve can be made of rubber, silicone, or other materials with high elasticity and abrasion resistance. These materials not only have good cushioning performance but also effectively isolate vibration, protecting the operator's hands from injury. Furthermore, the design of the flexible sleeve can take ergonomic principles into account, making it more suitable for the operator's grip habits and further enhancing the user experience. For example, raised or recessed textures can be provided in the grip area of ​​the handle 1 to increase friction, prevent slippage during operation, and improve grip stability.

[0040] The aforementioned vibratory plastering device connects the flexible trowel 2 and the handle 1 via multiple connecting rods 3. This allows the flexible trowel 2 to bend into a specific arc according to construction needs, adapting to different shaped construction surfaces. Especially when dealing with curved walls or columns, it enables uniform application of mortar, avoiding the low construction efficiency caused by the inability of traditional straight mortar boards to adhere to curved surfaces. Simultaneously, the vibration device on the handle 1 effectively drives the flexible trowel 2 to vibrate, helping to expel air bubbles from the mortar, improving the density and bonding strength of the mortar, and further enhancing the plastering quality.

[0041] The vibratory plastering device provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0042] In one specific implementation, reference is made to... Figure 1 The two ends of the multiple connecting rods 3 are respectively hinged to the handle 1 and the flexible shovel 2. Each connecting rod 3 is provided with an adjustment structure to adjust the distance between the handle 1 and the flexible shovel 2 at that point.

[0043] Specifically, each connecting rod 3 is hinged to both ends of the handle 1 and the flexible shovel 2. This hinged connection allows the flexible shovel 2 to bend flexibly relative to the handle 1, adapting to different curvatures of the work surface. To further enhance the device's applicability, each connecting rod 3 is equipped with an adjustment mechanism. This mechanism effectively adjusts the distance between the connection point A between the connecting rod 3 and the handle 1, and the connection point B between the connecting rod 3 and the flexible shovel 2. By changing the distance between A and B at multiple points on the flexible shovel 2, the flexible shovel 2 can bend to the desired curvature to adapt to different working environments.

[0044] Furthermore, the adjustment structure includes a slide groove 4 and an adjusting bolt 5. The slide groove 4 is formed on the corresponding connecting rod 3 and extends along the length of the connecting rod 3. The adjusting bolt 5 is slidably disposed in the slide groove 4 and is fixed between the slide groove 4 and the handle 1 by a positioning nut 6.

[0045] Specifically, such as Figure 1 and Figure 3 As shown, the slide groove 4 is opened along the length of the connecting rod 3. The adjusting bolt 5 is slidably set in the slide groove 4. The position of the adjusting bolt 5 in the slide groove 4 is fixed by the positioning nut 6, and the adjusting bolt 5 is fixed to the handle 1 by the positioning nut 6, thereby adjusting the curvature of the flexible ash shovel 2.

[0046] Optionally, the handle 1 has multiple slide openings in the vertical direction for mounting the connecting rod 3. The connecting rod 3 is slidably set in the corresponding slide opening. The position of the adjusting bolt 5 in the slide groove 4 is adjusted by loosening the positioning nut 6. After reaching the designated position, the position is fixed by the positioning nut 6, thereby completing the adjustment of the bending degree of the flexible ash shovel 2.

[0047] Based on any of the above embodiments, refer to Figure 1 and Figure 2 Each connecting rod 3 is provided with a hinge 7 at the end away from the handle 1. The hinge 7 is connected to the non-working surface of the flexible shovel 2 so that the connecting rod 3 is hinged to the flexible shovel 2.

[0048] Specifically, the hinge 7, as a connecting component, allows the flexible plaster trowel 2 to rotate and adjust its angle relative to the connecting rod 3 to a certain extent. This hinge allows the flexible plaster trowel 2 to adapt more flexibly to construction surfaces with different curvatures, ensuring smooth plastering operations. Figure 1 and Figure 2 In the illustration, we can see that the hinge 7 is installed at the end of the connecting rod 3 and connected to the non-working surface (i.e., the side that does not directly contact the mortar) of the flexible trowel 2. Through the design of the hinge 7, construction workers can adjust the curvature of the flexible trowel 2 according to actual construction needs. When facing curved walls or columns, simply adjust the length of the connecting rod 3 between the handle 1 and the flexible trowel 2 (as before, achieved through the groove 4 and adjusting bolt 5), and combine this with the rotation function of the hinge 7 to make the flexible trowel 2 conform to the construction surface. This improves the flexibility and efficiency of construction and also ensures the uniformity and consistency of plastering quality.

[0049] Optionally, the hinge 7 can be made of high-strength, corrosion-resistant materials and undergo precision machining and heat treatment to ensure that it will not fail due to excessive force or long-term wear during use.

[0050] Furthermore, a buffer pad 8 is provided between each hinge 7 and the flexible ash shovel 2.

[0051] Specifically, the buffer pad 8 effectively absorbs and disperses the vibration and impact forces transmitted from the connecting rod 3 to the flexible trowel 2. During plastering operations, the vibrating device generates vibrations. If these vibrations are directly transmitted to the flexible trowel 2, they may damage the trowel and even affect the plastering effect. The buffer pad 8 acts as a "shock absorber," effectively mitigating these vibrations and impact forces and protecting the flexible trowel 2 from damage. The buffer pad 8 also increases the contact area between the hinge 7 and the flexible trowel 2, improving the stability and durability of the connection. By increasing the contact area, the pressure per unit area can be reduced, thus avoiding damage to the connecting parts caused by localized stress concentration. Simultaneously, the softness and elasticity of the buffer pad 8 better accommodate the minor deformations of the flexible trowel 2 during operation, maintaining the tightness and reliability of the connection.

[0052] In summary, the buffer pad 8 effectively reduces rigid contact between the flexible trowel 2 and the connecting rod 3 during adjustment and use, preventing localized deformation or damage to the flexible trowel 2 due to concentrated force transmission, thereby extending the service life of the device. Simultaneously, the buffer pad enhances the stability of the flexible trowel 2 during adjustments at different curvatures, ensuring surface smoothness and consistent quality during plastering operations.

[0053] Optionally, the buffer pad 8 is a rubber buffer pad. Specifically, as a high-performance shock-absorbing material, the rubber buffer pad has excellent elasticity, wear resistance, and corrosion resistance, and is suitable for the connection between the hinge 7 and the flexible trowel 2. The rubber buffer pad also has a certain degree of wear resistance and corrosion resistance, and can maintain stable performance during use. Because the plastering operation environment is relatively harsh, dust, moisture, and other impurities may cause corrosion or wear to the connection parts. The wear resistance and corrosion resistance of the rubber buffer pad can effectively resist the effects of these adverse factors and extend the service life of the connection parts. At the same time, the rubber buffer pad is relatively inexpensive, easy to process and install. Through simple cutting and pasting processes, the rubber buffer pad can be installed at the connection between the hinge 7 and the flexible trowel 2 to achieve the effects of shock absorption and protection.

[0054] Optionally, the flexible trowel 2 is a rubber trowel. Specifically, the rubber trowel is made of high-strength rubber. High-strength rubber trowels have excellent flexibility, easily bending into various curves to closely conform to different shaped work surfaces. Whether it's a flat, curved, or irregular surface, the high-strength rubber trowel ensures even mortar application, significantly improving plastering quality. Simultaneously, high-strength rubber material is wear-resistant and corrosion-resistant. During plastering, the trowel needs to frequently come into contact with mortar and wall surfaces, making it susceptible to wear and corrosion. The high-strength rubber trowel can resist these adverse factors, extending its service life and reducing construction costs. The high-strength rubber trowel also has good elasticity, effectively buffering vibrations generated by vibration devices during plastering. This buffering effect not only reduces the formation of air bubbles in the mortar, improving its density and bonding strength, but also reduces operator hand fatigue, enhancing work comfort.

[0055] Based on any of the above embodiments, refer to Figure 1 and Figure 5 The vibratory plastering device provided by this utility model also includes a switch 9, and a storage battery 10 is built into the handle 1. The switch 9 is electrically connected between the storage battery 10 and the vibratory device.

[0056] Specifically, switch 9 allows operators to easily control the start and stop of the vibration device. When plastering work is required, the operator simply presses switch 9, and the battery 10 supplies power to the vibration device, causing it to start working and vibrate to remove air bubbles from the mortar and improve the plastering quality. When the work is completed or needs to be paused, the operator simply presses switch 9 again to cut off the power and stop the vibration device. The built-in battery 10 design eliminates the limitation of external power sources, improving the device's portability and applicability, especially demonstrating significant advantages in construction environments where power is scarce.

[0057] Furthermore, the vibration device includes a vibration motor 11, which is mounted on the handle 1.

[0058] Optionally, the vibratory motor 11 is a miniature vibratory motor. Specifically, miniature vibratory motors are small in size and lightweight, making the entire vibratory plastering device more portable, easy to carry, and easy to operate. Operators can hold it for extended periods without fatigue, thus improving work efficiency. Miniature vibratory motors typically have a high vibration frequency and moderate amplitude, generating sufficient vibration energy to effectively remove air bubbles from the mortar while avoiding excessive vibration or damage to the plastering surface.

[0059] Based on any of the above embodiments, refer to Figure 1 and Figure 5The vibratory plastering device provided by this utility model also includes a charging interface 12, which is disposed on the handle 1, and a converter 13 is electrically connected between the charging interface 12 and the storage battery 10.

[0060] Specifically, the charging interface 12 allows the vibratory plastering device to be conveniently charged, thereby extending its service life. Operators only need to insert the charger into the charging interface 12 to charge the battery 10 without disassembling the handle or the entire device, improving charging convenience and efficiency. The converter 13, as the electrical connection between the charging interface 12 and the battery 10, performs voltage conversion and current regulation. Since the output voltage and current of the external charger may not match the charging requirements of the battery 10, conversion and regulation are necessary through the converter 13 to ensure that the battery 10 can be charged safely and effectively.

[0061] In practical applications, converter 13 typically features multiple protection functions such as overcharge protection, over-discharge protection, and short-circuit protection to ensure the safety and stability of battery 10 during charging. Simultaneously, converter 13 can also achieve high conversion efficiency, reducing energy loss during charging and improving charging efficiency.

[0062] Furthermore, the charging port 12 and converter 13 are designed with waterproof and dustproof protection measures in mind to adapt to different construction environments. These protective measures ensure that the charging port 12 and converter 1 can still function normally under harsh construction conditions, extending their service life.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0064] The above provides a detailed description of the vibratory plastering device provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
