Description

Technical Field

[0001] This utility model belongs to the field of building construction tools technology, specifically relating to a building wall plastering device. Background Technology

[0002] In building wall plastering projects, plastering rollers are widely used due to their efficient and uniform coating capabilities. Traditional plastering rollers typically consist of a fixedly connected handle and roller, arranged in a perpendicular cross structure (i.e., the handle and roller axis form a 90° angle). This design performs well in plastering open wall surfaces. However, in actual projects, walls often have narrow areas such as around door and window frames, corners, and pipe shafts. The fixed structure of traditional rollers reveals the following significant defects:

[0003] 1. Limited operation in confined spaces

[0004] When a narrow area of ​​the wall needs to be brushed horizontally, the operator must hold the handle vertically. At this time, the roller is in a horizontal position, which may make it difficult to reach the narrow area due to insufficient space. If the operation is forced, it may cause mortar to splash out or the brushing to be uneven.

[0005] 2. Limitations of grip direction switching

[0006] If the handle is changed to a horizontal grip so that the roller can enter the narrow area vertically, the horizontal grip itself will take up extra space, further hindering the operation, and may even cause the roller to go out of control due to an unstable grip, affecting construction efficiency and safety.

[0007] 3. Lack of dynamic adaptability

[0008] The fixed structure of traditional rollers cannot adjust the angle in real time according to the wall structure. Operators need to frequently change tools or adjust their positions, which increases labor intensity and reduces the continuity of work.

[0009] Therefore, this utility model proposes a building wall plastering device. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1 to 4 This is the first embodiment of the present utility model, which provides a technical solution: a building wall plastering device, comprising...

[0031] 2. Handle; 3. Top seat welded and fixed to the top surface of handle 2; 4. Rotatable support plate set on the left side surface of top seat 3; 5. Two side plates welded and fixed to the left side surface of support plate 4; 6. Roller 6 installed between the two side plates 5 via a rotating shaft. The outermost layer of roller 6 is wrapped with a layer of polyester fiber felt. The polyester fiber felt absorbs the water in the mortar through capillary action to form a stable mortar film. In actual plastering, simply hold handle 2 and roll the roller 6 with mortar onto the wall to perform the plastering operation.

[0032] A shaft block 8 is fixed on the right side surface of the support plate 4, and the top seat 3 is rotatably sleeved on the surface of the shaft block 8, so that the support plate 4 can rotate the roller 6 on the left side of the top seat 3, thereby realizing the rotation adjustment of the roller 6 angle. The operator can quickly rotate and adjust the roller 6 according to the actual operation needs, easily cope with narrow areas such as door and window frames and wall corners, and the handle 2 always maintains a comfortable grip posture, such as horizontal roller brushing in narrow areas or vertical roller brushing in open areas.

[0033] A locking structure is provided between the handle 2 and the shaft block 8 to lock the support plate 4 and the shaft block 8 after rotation adjustment, ensuring stability during daily use.

[0034] In this embodiment, preferably, the locking structure includes a latching block 71 movably mounted on the right side surface of the grip 2, a movable locking rod 72 welded and fixed to the top surface of the latching block 71, and four limiting slots 73 evenly provided on the surface of the shaft block 8 corresponding to the movable locking rod 72. The top end of the movable locking rod 72 is inserted into one of the limiting slots 73 to achieve stable positioning of the shaft block 8, the support plate 4, and the roller 6 during daily use. The locking structure also includes a strip-shaped sliding opening 74 on the surface of the grip 2, a guide rod 76 fixed in the strip-shaped sliding opening 74, an inner slider 75 located in the strip-shaped sliding opening 74 and movably sleeved on the surface of the guide rod 76, and a spring 77. The right end of the inner slider 75 extends to the right side surface of the grip 2 and is fixed to the latching block 71. Under the pushing of the spring 77, the top end of the movable locking rod 72 can be stably locked in one of the limiting slots 73 during daily use, ensuring the positioning of the shaft block 8. The limiting stability of block 8, support plate 4, and roller 6 is ensured. If roller 6 needs to be rotated later, the operator simply needs to use their finger to push down the latch block 71, causing the inner slider 75 to slide down and compress the spring 77. This causes the top of the movable lever 72 to move out of the limiting slot 73, quickly releasing the limiting of block 8, support plate 4, and roller 6. At this point, support plate 4 can be rotated to the left of top seat 3 to achieve rotational adjustment of roller 6. After roller 6 rotates 90 degrees, another limiting slot 73 will align with the movable lever 72. The operator then simply needs to release the latch block 71, causing the spring 77 to push the inner slider 75 back, and the top of the movable lever 72 to engage in the limiting slot 73. This quickly completes the limiting of block 8, support plate 4, and roller 6, allowing roller 6 to be quickly rotated 90 degrees according to actual usage requirements, satisfying different usage scenarios and needs.

[0035] In this embodiment, preferably, the bottom end of the spring 77 abuts against the inner wall of the bottom end of the strip-shaped sliding opening 74, and the top end of the spring 77 abuts against the bottom surface of the inner slider 75.

[0036] In this embodiment, preferably, the surface of the inner slider 75 is provided with a sleeve hole that matches the guide rod 76, so that the inner slider 75 can be smoothly slidably sleeved on the guide rod 76, and the inner slider 75 can then smoothly slide up and down.

[0037] In this embodiment, preferably, a handle sleeve 1 is fixed to the bottom surface of the handle 2 to facilitate the operator's grip on the handle 2.

[0038] Example 2

[0039] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that the sealing gasket 9 can be set to prevent some foreign objects from entering the strip-shaped sliding opening 74 during daily use.

[0040] Specifically, a sealing gasket 9 is installed on the left side surface of the grip 2, and the sealing gasket 9 covers the strip-shaped sliding opening 74, which can prevent foreign objects from entering the strip-shaped sliding opening 74 during daily use.

[0041] In this embodiment, preferably, the side of the sealing gasket 9 is provided with two integrated plugs 91, and the side of the plugs 91 is provided with an integrated triangular side locking block 92. Both are made of rubber and will undergo elastic deformation when squeezed. The inner wall of the strip-shaped sliding opening 74 is provided with a side locking groove 741 corresponding to the triangular side locking block 92. The plugs 91 are inserted into the strip-shaped sliding opening 74, and the triangular side locking block 92 is embedded in the side locking groove 741, which can stably limit the sealing gasket 9 and ensure the installation stability of the sealing gasket 9 during daily use. If the sealing gasket 9 needs to be removed later, simply pull the sealing gasket 9 to the side, so that the triangular side locking block 92 is squeezed and undergoes elastic deformation until the triangular side locking block 92 is squeezed out from the side locking groove 741, and the sealing gasket 9 can be easily removed from the side of the handle 2. After the sealing gasket 9 is no longer obstructed, the inside of the strip-shaped sliding opening 74 can be cleaned and maintained.

[0042] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
