Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to an adjustable auxiliary device for plastering building walls. Background Technology
[0002] Wall plastering is an important step in building construction, referring to the application of one or more layers of mortar to the wall surface to achieve leveling, protection, decoration, or improvement of wall performance. It is a fundamental step in building decoration, directly affecting the quality of subsequent painting, tiling, and other construction work. Wall plastering auxiliary devices are tools or equipment used in building construction for wall plastering, primarily to improve the smoothness, verticality, and efficiency of the plastering process.
[0003] After cement is applied to the wall, to ensure a smooth surface, workers typically use a plastering device against the wall, ensuring the side of the device is in contact with the wall surface for smoothing. Current wall plastering devices require the operator to hold the device and repeatedly scrape with wrist force when using it. Moving the device up and down requires continuous internal and external wrist rotation. Existing solutions are insufficient in terms of angle adjustment, quick locking, and stability, leading to poor wrist posture and fatigue during frequent posture changes. Utility Model Content
[0004] The purpose of this utility model is to provide an adjustable auxiliary device for plastering building walls, in order to solve the problem mentioned in the background art that the existing wall decoration plastering devices require the user to hold the device and repeatedly scrape with wrist force when using them. When moving the plastering device up and down, the operator needs to continuously perform internal / external rotation of the wrist joint. Long-term operation can lead to occupational diseases such as tenosynovitis and carpal tunnel syndrome, which brings a great health burden and economic loss to the user.
[0005] To solve the above problems, this utility model provides the following technical solution: an adjustable building wall plastering auxiliary device, including a scraper and a gripping part:
[0006] The scraper has a vertical plate on its side and a connecting post on its top surface. The grip is located on the top surface of the scraper and has a rotating shaft rotatably mounted on the top surface of the connecting post. The top surface of the rotating shaft has a rotating joint, and the top surface of the rotating joint has a handle. An adjusting block is laterally slidably mounted inside the handle, and one end of the adjusting block has a locking head that engages with the rotating joint to fix the tilt angle of the handle.
[0007] By adopting the above technical solution, the relative horizontal angle between the scraper and the handle can be adjusted by rotating the rotating shaft on the connecting pile. At the same time, the handle can be rotated by using the rotating joint, and the tilt angle of the handle can be flexibly fixed by engaging the clamp with the rotating joint to adapt to different wall plastering angle requirements. This makes it convenient for construction workers to perform wall plastering operations in various positions and angles, improving work efficiency and construction quality.
[0008] Preferably, the grip also has a slider that slides vertically and is nested outside the rotating shaft, and a spring a is nested outside the rotating shaft, the spring a being disposed between the rotating joint and the slider.
[0009] By adopting the above technical solution, the slider can slide vertically on the rotating shaft, and the spring a plays a role in resetting. When an external force is applied to the slider, the spring a is compressed and the slider slides upward. After the slider is released, the spring a restores its elastic deformation and pushes the slider downward to reset.
[0010] Preferably, the gripping part also has a stud provided at the bottom of the slider, and a limiting hole a is provided at the top of the connecting stud, and the stud is inserted into the limiting hole a and engaged with the connecting stud.
[0011] By adopting the above technical solution, when the slider slides down, the insertion stake can be embedded into the limiting hole a at the top of the connecting stake, thereby achieving the engagement and fixation of the gripping part and the scraper, restricting the horizontal rotation of the rotating shaft on the connecting stake, and ensuring the stability of the relative position of the scraper and the gripping part during the wall plastering process.
[0012] Preferably, the grip portion also has a limiting block disposed on the side of the rotation axis, which is vertically slidably connected to the slider.
[0013] By adopting the above technical solution, the vertical sliding of the slider can be guided and limited by the limiting block, ensuring that the slider can only slide vertically along the axial direction of the rotation axis, and preventing the slider from deviating or shaking during the sliding process.
[0014] Preferably, the gripping part also has several limiting holes b opened inside the rotating joint, and the locking head engages with the limiting holes b.
[0015] By adopting the above technical solution, when adjusting the tilt angle of the handle, the locking head can be inserted into the limiting hole b at different positions to fix the handle at multiple tilt angles.
[0016] Preferably, the surface of the grip has grooves that fit the fingers, and the top of the adjustment block extends to the outside of the grip and has anti-slip texture.
[0017] By adopting the above technical solution, construction workers can better fit their fingers into the grooves on the handle surface when holding the handle, increasing the comfort and stability of the grip. The anti-slip texture on the top of the adjustment block makes it easy for construction workers to push the adjustment block to slide laterally inside the handle with their fingers.
[0018] Preferably, the grip portion also has a spring b disposed inside the handle, the spring b being located between the adjusting block and the handle.
[0019] By adopting the above technical solution, when the adjusting block is pushed to disengage the chuck from the limiting hole b, the spring b is compressed. When the adjusting block is released, the spring b restores its elastic deformation, pushes the adjusting block to reset, and allows the chuck to automatically engage in the corresponding limiting hole b, ensuring the fixing effect after the handle tilt angle is adjusted.
[0020] Preferably, one end of the card head is provided with a chamfered arc surface.
[0021] By adopting the above technical solution, the chuck can slide into or out of the limiting hole b more easily, reducing friction and jamming between the chuck and the rotating joint.
[0022] Compared with the prior art, the beneficial effects of this utility model are: by providing a gripping part, the relative horizontal angle between the scraper and the gripping part can be adjusted by rotating the rotating shaft on the connecting pile. At the same time, the handle can be rotated by using the rotating joint, and the tilt angle of the handle can be flexibly fixed by engaging the clamp head with the rotating joint to adapt to different wall plastering angle requirements. This makes it convenient for construction workers to perform wall plastering operations in various positions and angles, improving work efficiency and construction quality.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Example 1
[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: an adjustable building wall plastering auxiliary device, including a scraper 1 and a gripping part 2.
[0034] A vertical plate 101 is vertically installed on the side of the scraper 1, which facilitates the operator to apply the coating to the inside corners of the wall. A connecting post 102 is installed on the top surface of the scraper 1. A grip 2 is installed on the top surface of the scraper 1. The grip 2 has a rotating shaft 201 rotatably installed on the top surface of the connecting post 102. A rotating joint 203 is installed on the top surface of the rotating shaft 201. A handle 208 is rotatably installed on the top surface of the rotating joint 203. An adjusting block 209 is slidably installed laterally inside the handle 208. A locking head 210 is installed at one end of the adjusting block 209. The locking head 210 is connected to... The swivel joint 203 engages to fix the tilt angle of the handle 208. The relative horizontal angle between the scraper 1 and the gripping part 2 can be adjusted by rotating the swivel shaft 201 on the connecting pile 102. At the same time, the swivel joint 203 allows the handle 208 to rotate. When the construction worker adjusts the handle 208 to a suitable tilt angle, the engagement of the locking head 210 with the swivel joint 203 keeps the handle 208 at that angle. This makes it convenient for the construction worker to perform wall plastering operations in various positions and angles, effectively improving work efficiency and construction quality.
[0035] Example 2
[0036] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: an adjustable building wall plastering auxiliary device, including a scraper 1 and a gripping part 2.
[0037] A slider 204 is vertically nested outside the rotating shaft 201, and a spring a206 is nested outside the rotating shaft 201. The spring a206 is located between the rotating joint 203 and the slider 204.
[0038] The slider 204 can slide vertically on the rotating shaft 201. The spring a206 plays a role in resetting. When an external force is applied to the slider 204, the spring a206 is compressed and the slider 204 slides upward. After the slider 204 is released, the spring a206 restores its elastic deformation and pushes the slider 204 to reset downward.
[0039] A stake 205 is integrally provided at the bottom of the slider 204. A limiting hole a103 is provided at the top of the connecting stake 102. The stake 205 is inserted into the limiting hole a103 and engaged with the connecting stake 102. When the slider 204 slides down, the stake 205 is inserted into the limiting hole a103 at the top of the connecting stake 102, thereby achieving the engagement and fixation of the gripping part 2 and the scraper 1, restricting the horizontal rotation of the rotating shaft 201 on the connecting stake 102, and ensuring the stability of the relative position of the scraper 1 and the gripping part 2 during the wall plastering process.
[0040] A limit block 202 is integrally provided on the side of the rotating shaft 201. The limit block 202 is vertically slidably connected to the slider 204. The limit block 202 can be used to guide and limit the vertical sliding of the slider 204, ensuring that the slider 204 can only slide vertically along the axial direction of the rotating shaft 201, and preventing the slider 204 from deviating or shaking during the sliding process.
[0041] Several limiting holes b207 are provided inside the rotating joint 203. The locking head 210 is engaged with the limiting holes b207. When adjusting the tilt angle of the handle 208, the locking head 210 can be inserted into the limiting holes b207 at different positions to fix the handle 208 at multiple tilt angles.
[0042] Example 3
[0043] Please see Figure 5 , Figure 6 and Figure 7 This embodiment provides a technical solution: an adjustable building wall plastering auxiliary device, including a gripping part 2:
[0044] The surface of the handle 208 is provided with grooves that fit the fingers. The top of the adjustment block 209 extends to the outside of the handle 208 and is provided with anti-slip texture. This allows the fingers of the construction worker to better fit the grooves on the surface of the handle 208 when holding the handle 208, increasing the comfort and stability of the grip. The anti-slip texture on the top of the adjustment block 209 makes it easy for the construction worker to push the adjustment block 209 to slide laterally inside the handle 208 with their fingers.
[0045] A spring b211 is provided inside the handle 208. The spring b211 is located between the adjusting block 209 and the handle 208. When the adjusting block 209 is pushed to disengage the locking head 210 from the limiting hole b207, the spring b211 is compressed. When the adjusting block 209 is released, the spring b211 restores its elastic deformation, pushes the adjusting block 209 to reset, and allows the locking head 210 to automatically lock into the corresponding limiting hole b207, ensuring the fixing effect after the tilt angle of the handle 208 is adjusted.
[0046] One end of the chuck 210 is provided with a chamfered arc surface, which makes it easier for the chuck 210 to slide into or out of the limiting hole b207, reducing friction and jamming between the chuck 210 and the rotating joint 203.
[0047] Working principle: First, construction workers can flexibly adjust the relative position and angle of the scraper 1 and the grip 2 according to different positions and angles of the wall. For adjusting the horizontal angle, the relative horizontal angle between the scraper 1 and the grip 2 is changed by rotating the rotating shaft 201 on the connecting pile 102, thus meeting the construction requirements of different wall positions. For adjusting the tilt angle of the handle 208, the construction worker pushes the adjusting block 209, causing the locking head 210 to disengage from the limiting hole b207. At this time, the spring b211 is compressed, and then the grip is rotated. When the handle 208 is tilted to a suitable angle, the adjusting block 209 is released, the spring b211 returns to its elastic deformation, and the adjusting block 209 is pushed back to its original position, so that the locking head 210 automatically engages in the corresponding limiting hole b207, thus fixing the handle 208 at this tilt angle. This allows construction personnel to operate in a comfortable posture. When it is necessary to fix the relative position of the grip 2 and the scraper 1 and restrict the horizontal rotation of the rotating shaft 201 on the connecting pile 102, the construction personnel push the slider 204 upward, the spring a206 is compressed, and the slider 204 moves along the rotation... The rotating shaft 201 slides upward, and the limiting block 202 guides and limits the sliding of the slider 204 to prevent it from deviating or wobbling. When the slider 204 slides to the appropriate position, it is released, the spring a206 returns to its elastic deformation, and pushes the slider 204 downward to reset, so that the insertion post 205 is embedded in the limiting hole a103 at the top of the connecting post 102, realizing the engagement and fixation of the gripping part 2 and the scraper 1. This allows the gripping part 2 to be adjusted at the horizontal angle of the top of the scraper 1, ensuring the relative position of the scraper 1 and the gripping part 2 during the wall plastering process. In terms of stability, during construction, the upright plate 101 on the side of the scraper 1 makes it convenient for operators to apply plaster to the inside corners of the wall. The groove on the surface of the handle 208 that fits the fingers and the anti-slip texture on the top of the adjustment block 209 increase the comfort of holding and the convenience of operation. The chamfered arc surface at one end of the clamp 210 makes the clamp 210 slide into or out of the limiting hole b207 more smoothly, reducing friction and jamming, improving the overall efficiency and service life of the device, thereby effectively improving the work efficiency and construction quality of wall plastering.
