[0002] In existing technology, plastering boards are key equipment used for applying mortar to walls during building construction. Traditional plastering boards are mostly flat boards. When working on inside corners, both sides of the inside corner need to be worked on separately, which is inefficient and can easily leave joint marks, affecting the construction quality. Utility Model Content

[0003] To overcome the shortcomings of traditional plastering boards, which are mostly flat boards, requiring separate construction on both sides of the inside corner when working on it, resulting in low efficiency and easy appearance of joint marks that affect the construction quality, this utility model provides a hinged, adjustable-angle plastering device.

[0004] The technical solution is as follows: a hinged adjustable angle plastering device, comprising: a plastering board, consisting of a first plate and a second plate that are in contact with each other, wherein a plurality of connecting parts are fixedly connected between the first plate and the second plate; an angle adjustment unit, installed on the first plate and the second plate; and a handle, fixedly connected to the angle adjustment unit via a connecting block.

[0005] As an improvement to the above solution, the connecting member is configured as a hinge, and the center of the hinge rotation axis is in the same plane as the contact surfaces of the first plate and the second plate.

[0006] As an improvement to the above solution, the angle adjustment unit includes two arc-shaped sliding sleeves disposed above the plastering board and four arc-shaped sliding rods slidably connected to the two ends of the two arc-shaped sliding sleeves respectively. The four arc-shaped sliding rods are fixedly connected to the first plate and the second plate in pairs.

[0007] As an improvement to the above solution, it also includes a mating block used as a peripheral accessory. The mating block is provided with two symmetrical protrusions. The first plate and the second plate have mating grooves on opposite sides that match the protrusions on the mating block. The mating block is provided with various specifications.

[0008] As an improvement to the above solution, it also includes two sets of insert rods that are respectively inserted into the first plate and the second plate. The two insert rods form a set, and the two protrusions of the mating block are each provided with a hole corresponding to each set of insert rods.

[0009] As an improvement to the above solution, each of the insertion rods is provided with a threaded portion, and the first plate and the second plate are provided with corresponding threaded holes.

[0010] As an improvement to the above solution, it also includes a sealing block adapted to the mating grooves on the opposite sides of the first plate and the second plate, and the sealing block also has a socket corresponding to each set of plug rods.

[0011] As an improvement to the above solution, the hinge is configured as a damped hinge.

[0012] As an improvement to the above solution, the arc-shaped slide bar is provided with scale lines and numbers for cooperating with the arc-shaped sliding sleeve to indicate the included angle between the first plate and the second plate.

[0013] This utility model has the following advantages: by screwing the insert rod into the corresponding threaded hole, the stability of the insert rod locking the mating block is ensured, thus making the mating block, the first plate, and the second plate a stable assembly. This avoids misalignment of the mating block with the first and second plates during use, which would affect the construction quality. As a result, the operator can simultaneously work on both sides of the inside corner. Compared with traditional plastering boards, this improves construction efficiency and avoids joint marks caused by separate work on both sides of the inside corner, thereby improving construction quality. Furthermore, it can be adjusted to various angles according to the needs of the construction site, making it highly adaptable and increasing its practicality. Attached Figure Description

[0016] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0017] Example A hinged, adjustable-angle plastering device, according to Figures 1-5As shown, it includes: The plastering board 1 is composed of a first plate 101 and a second plate 102 that are in contact with each other, and a number of connectors 2 are fixedly connected between the first plate 101 and the second plate 102. Angle adjustment units are mounted on the first plate 101 and the second plate 102; and The handle 5 is fixed to the angle adjustment unit via a connecting block.

[0018] The connector 2 is configured as a hinge, and the center of the hinge rotation axis is in the same plane as the contact surfaces of the first plate 101 and the second plate 102.

[0019] The angle adjustment unit includes two arc-shaped sliding sleeves 4 disposed above the plastering board 1 and four arc-shaped sliding rods 3 slidably connected to the two ends of the two arc-shaped sliding sleeves 4 respectively. The four arc-shaped sliding rods 3 are fixedly connected to the first plate 101 and the second plate 102 in pairs.

[0020] It also includes a fitting block 6 used as a peripheral accessory. The fitting block 6 has two symmetrical protrusions. The first plate 101 and the second plate 102 have mating grooves on opposite sides that match the protrusions on the fitting block 6. The fitting block 6 is available in various sizes to accommodate the first plate 101 and the second plate 102 at different angles for use.

[0021] It also includes two sets of insert rods 7 that are respectively inserted into the first plate 101 and the second plate 102. The two insert rods 7 form a set. The two protrusions of the mating block 6 are each opened with a corresponding insertion hole. By inserting the four insert rods 7 into the first plate 101 and the second plate 102, and making the end of each insert rod 7 inserted into the corresponding insertion hole, the mating block 6 is limited, so that the mating block 6 and the first plate 101 and the second plate 102 form a stable assembly, and avoid misalignment of the mating block 6 and the first plate 101 and the second plate 102 during use, which would affect the construction quality.

[0022] Each of the insert rods 7 is provided with a threaded portion 701. The first plate 101 and the second plate 102 are provided with corresponding threaded holes. When the insert rod 7 is inserted into the first plate 101 and the second plate 102 to lock the mating block 6, the threaded portion 701 is screwed into the corresponding threaded hole by turning the insert rod 7, thereby ensuring the stability of the lock of the insert rod 7 on the mating block 6.

[0023] It also includes a sealing block 8 that is adapted to the mating grooves on the opposite sides of the first plate 101 and the second plate 102, and the sealing block 8 also has a hole corresponding to each set of insert rods 7. When the plastering board 1 is used as a flat plate, the mating groove is sealed by the sealing block 8 to prevent mortar from entering and causing blockage, which would affect the subsequent insertion of the mating block 6.

[0024] The hinge is a damped hinge, which facilitates the adjustment of the angle between the first plate 101 and the second plate 102.

[0025] The arc-shaped slide bar 3 is provided with scale lines and numbers for cooperating with the arc-shaped slide sleeve 4 to indicate the angle between the first plate 101 and the second plate 102. During the adjustment process, the angle formed by the first plate 101 and the second plate 102 can be known by observing the scale lines and numbers at the end of the arc-shaped slide sleeve 4, which facilitates quick and accurate adjustment.

[0026] During construction, the plasterboard 1 can be used directly as a flat plate as needed. The sealing block 8 seals the fitting groove. The insert rod 7 is inserted into the first flat plate 101 and the second flat plate 102. By screwing the insert rod 7, the threaded part 701 is screwed into the corresponding threaded hole, allowing the end of the insert rod 7 to insert into the insertion hole on the sealing block 8. This ensures a stable sealing effect of the sealing block 8 during the use of the plasterboard 1, preventing mortar from entering and causing blockages that could affect the subsequent insertion of the fitting block 6. If it is necessary to adjust the angle between the first flat plate 101 and the second flat plate 102, the locking of the insert rod 7 onto the sealing block 8 is released, and the sealing block 8 is removed. Then, the operator pulls the first flat plate 101 and the second flat plate 102 towards the handle 5, causing them to rotate around the hinge axis. Simultaneously, the arc-shaped sliding rod 3 slides within the arc-shaped sliding sleeve 4. By observing the scale lines and numbers on the arc-shaped sliding sleeve 4 corresponding to the arc-shaped sliding rod 3, the first flat plate 101 and the second flat plate 102 are aligned. The plate 102 can be adjusted by rotating it to a preset angle. Then, the matching mating block 6 is inserted between the first plate 101 and the second plate 102, so that the two protrusions on the mating block 6 are inserted into the fitting grooves of the first plate 101 and the second plate 102. Then, the threaded part 701 is screwed into the corresponding threaded hole by turning the insertion rod 7, thereby ensuring the stability of the locking of the insertion rod 7 to the mating block 6. This makes the mating block 6 and the first plate 101 and the second plate 102 a stable combination, avoiding misalignment of the mating block 6 and the first plate 101 and the second plate 102 during use, which would affect the construction quality. The state is shown in the figure. Then it can be used. The operator can simultaneously construct both sides of the inside corner. Compared with the traditional plastering board 1, it improves the construction efficiency and avoids the joint marks caused by constructing the two sides of the inside corner separately, thereby improving the construction quality. Moreover, it can be adjusted to various angles according to the needs of the construction site, which has strong adaptability and increases practicality.
