Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a construction tool for plastering internal and external corners. Background Technique

[0002] The plastering boards for internal and external corners are usually divided into external corner plastering boards and internal corner plastering boards according to the direction of the handle. In order to make the construction more convenient, at present, there are already plastering boards that can be used for both internal and external corner plastering by rotating the handle, but the position of the rotating handle cannot be adjusted. When plastering internal and external corners, the position of the handle and the plastering board is fixed, resulting in problems such as uncomfortable operation and inconvenient observation. For example, when the handle is in a suitable position during external corner construction, after rotation and conversion to internal corner construction, the handle may be too close to the two side plates, making it inconvenient for construction workers to operate and observe. Moreover, different workers have different operating habits, and the non-adjustable position of the handle also makes its applicability poor. In addition, the current handle rotation and fixation method is not convenient enough, resulting in inconvenient use and adjustment.

[0003] Therefore, how to solve the above technical problems becomes the topic faced by the utility model. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a construction tool for plastering internal and external corners with stronger applicability and convenient adjustment.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the utility model provides a construction tool for plastering internal and external corners, which includes two plastering boards arranged at a 90-degree angle. Between the upper and lower sides of each plastering board, there is a handle. Both ends of the handle are connected with an angle adjustment and fixation component, and the angle adjustment and fixation component is connected with a sliding component.

[0006] Both inner sides of the two plastering boards are provided with through grooves from top to bottom. The sliding component includes a sliding block slidably connected to the center of the inner side of the through groove. Vertically arranged connecting rods are fixedly connected to the centers of the upper and lower sides of the sliding block. One end of each connecting rod away from the sliding block is fixedly connected with a connecting block slidably matched with the inner side of the through groove. The connecting block is fixedly connected with a mounting plate on the side away from the connecting rod. The two mounting plates are respectively located outside the two sides of the through groove, and the mounting plate is connected with the angle adjustment and fixation component.

[0007] A vertical installation cavity is provided inside the intersection of the two plastering boards. A threaded hole is horizontally opened through the center of the sliding block. A threaded rod is threadedly connected to the inner side of the threaded hole. One end of the two adjacent threaded rods is coaxially sleeved with a first bevel gear, and the two first bevel gears are meshed with both sides of the second bevel gear located above them;

[0008] The second bevel gear is coaxially sleeved outside the rotating rod, the rotating rod is vertically rotatably connected to the inside of the installation cavity, and the top end of the rotating rod extends above the plastering board and is coaxially and fixedly connected with a knob.

[0009] The angle adjustment and fixing component includes an upper connecting cylinder and a lower connecting cylinder respectively fixedly connected to the upper and lower mounting plates. A through top hole is formed at the top of the upper connecting cylinder, and a through bottom hole is formed at the bottom of the lower connecting cylinder;

[0010] A top rod is vertically arranged at the central part inside the upper connecting cylinder. A turntable is rotatably connected to the outer side of the bottom of the top rod. An upper gear that is rotationally and slidably matched with the top rod is coaxially sleeved on the outer side of the upper part of the top rod. A spring is fixedly connected between the top of the turntable and the bottom of the upper gear;

[0011] A plurality of insertion rods are vertically arranged equidistantly along the circumferential direction near the edge of the turntable. The insertion rods penetrate through the upper gear and are slidably matched with the penetrating part of the upper gear. The top of the upper gear is fixedly connected to the top of the handle;

[0012] An upper tooth ring that is meshed and matched with the upper gear is arranged above the inside of the upper connecting cylinder.

[0013] A bottom rod is vertically arranged at the central part inside the lower connecting cylinder. A lower gear that is rotationally and slidably matched with the bottom rod is coaxially arranged on the outer side of the bottom rod. A lower tooth ring that is meshed and matched with the lower gear is arranged above the inside of the lower connecting cylinder;

[0014] The bottom of the lower gear is fixedly connected to the bottom of the handle.

[0016] A handle sleeve is sleeved on the outer side of the handle, and the outer wall of the handle sleeve is in a multi-edge shape.

[0017] When the utility model is actually used: Determine the direction of the handle according to the plastering of the internal angle or external angle. When the handle needs to be rotated, hold the handle and press it down as a whole. The upper fixing rod pushes the upper gear to move downward and disengage from the upper tooth ring, and at the same time drives the lower gear to move downward and disengage from the lower tooth ring. Immediately, the locking state of the handle is released. Then rotate the handle to a suitable position on the other side of the plastering board and release the handle. Under the action of the spring, the upper gear meshes with the upper tooth ring again, and the lower gear meshes with the lower tooth ring to lock the position of the handle. The support point positions of the two handles can be synchronously adjusted by rotating the knob according to the operating habits of the operator and the on-site situation.

[0018] The beneficial effects of the utility model are:

[0019] 1. By rotating the handle of the utility model, the plastering board can be used for plastering the external corner and the internal corner.

[0020] 2. By changing the support point of the handle of the utility model, the handle has stronger applicability. Whether it is for plastering the internal corner or the external corner, or there are certain differences in the operating habits of construction workers, the plastering operation can be carried out conveniently and comfortably.

[0021] 3. The angle adjustment and fixing component of the utility model is arranged so that the locking state of the handle can be quickly released by pressing, and the locking state can be restored by releasing the handle, and the operation is flexible and convenient.
