Abstract
Description
Technical Field
[0001] This application relates to the field of building construction equipment technology, and specifically discloses an adjustable angle corner puller. Background Technology
[0002] In the construction process of building projects, the general procedure for applying cement mortar plaster to the inside and outside corners is to first use a square ruler to find the square of the inside and outside corners, then make baselines on both sides of the inside and outside corners, and then pop up the plastering control lines. Finally, mark the inside and outside corners on both sides and use a regular trowel to mark the height of the bottom screed to ensure that the plastered inside and outside corners are vertical.
[0003] However, in traditional construction processes, when using only ordinary mortar trowels, it is not easy to meet the standards for the verticality and squareness of the inside and outside corners. Therefore, the prior art provides a corner puller specifically used in the construction of inside and outside corners to perform plastering at a fixed angle.
[0004] In existing technologies, corner brackets are mainly composed of two plasterboards joined together, usually by welding or keying, to achieve uniform verticality and squareness during plastering. However, in practical applications, the angles of inside and outside corners vary depending on the construction standards and the angle of the corner, and existing corner brackets typically do not have angle adjustment capabilities.
[0005] Therefore, the inventor has provided an adjustable angle corner puller to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to solve the problem that traditional corner pullers used for plastering the inside and outside corners during plastering construction do not have an angle adjustment function.
[0007] To achieve the above objectives, the basic solution of this utility model provides an adjustable angle corner puller, including a first gray plate and a second gray plate, a first connector on one side of the first gray plate, and a second connector on one side of the second gray plate;
[0008] It also includes an angle adjusting component for connecting the first connector and the second connector. When the first connector and the second connector are connected by the angle adjusting component, the adjacent side edges of the first gray plate and the second gray plate fit together and form a gap for accommodating the inside and outside corners. The angle adjusting component includes a positioning sleeve for connecting the second connector, a connecting rod that is slidably connected to the positioning sleeve and rotatable, and a fixing component that is detachably connected to both ends of the positioning sleeve and used to fix the connecting rod. The connecting rod is also provided with a connecting structure for connecting the first connector.
[0009] Furthermore, the positioning sleeve has an exposed slot for the connecting structure to be exposed, and both the first and second connecting members have coaxial through holes for the positioning sleeve to pass through. The first connecting member also has a first connecting slot that communicates with the through hole and allows the connecting structure to extend into it.
[0010] Furthermore, both ends of the connecting rod are provided with external threads, and both ends of the positioning sleeve are provided with internal threads that are respectively threaded to the external threads at both ends of the connecting rod.
[0011] Furthermore, the fixing components are a top nut and a bottom nut that are respectively threaded onto the connecting rods on the outer sides of both ends of the positioning sleeve.
[0012] Furthermore, the connection structure includes a first connecting plate that is vertically slidably connected to the connecting rod and snapped into the first connecting member.
[0013] Furthermore, the two ends of the first connecting plate are respectively provided with a rotating structure that is rotatably connected to the inside of the exposed slot.
[0014] Furthermore, a second connecting plate that engages with the second connecting member is fixedly connected to the outer side of the positioning sleeve.
[0015] The principle and effect of this solution are as follows:
[0016] 1. Compared with the prior art, this utility model uses an angle adjustment component to combine and install the first connecting component and the second connecting component. In this way, the first and second plaster boards are combined and assembled into a complete corner puller. The angle adjustment component can be used to adjust and fix the angle of the first and second plaster boards, thereby adapting to different angles of inside and outside corners in different construction sites. This solves the problem that traditional corner pullers used for plastering both sides of inside and outside corners in the plastering process do not have an angle adjustment function.
[0017] 2. Compared with the prior art, the angle adjustment component of this utility model adjusts the gap between the first and second gray plates by rotating the connecting rod. The rotation adjustment method can make the inner walls of the first and second gray plates fit together at the inside and outside corners more quickly, and the angle can be directly fixed by the fixing component, which is convenient to use.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0023] The reference numerals in the accompanying drawings include: first gray plate 1, second gray plate 2, first adjusting plate 3, second adjusting plate 4, connecting rod 5, positioning sleeve 6, handle 7, top nut 8, bottom nut 9, first connecting plate 10, second connecting plate 11, T-shaped ring platform 12, limiting block 13, locking key 14, limiting cross block 15, and T-shaped ring groove 16.
[0024] An adjustable angle corner puller, for example, Figure 1 As shown:
[0025] It includes a first gray plate 1, a second gray plate 2, and angle adjusting components. Two sets of first adjusting components are provided on the inner side of the first gray plate 1, and two sets of second adjusting components are correspondingly provided on the inner side of the second gray plate 2. The angle adjusting components connect the first and second adjusting components, and make the adjacent edges of the first gray plate 1 and the second gray plate 2 fit together, forming a gap for accommodating inside and outside corners.
[0026] The first adjusting component includes two first adjusting plates 3 welded to the inner side of the first gray plate 1, and the second adjusting component includes a second adjusting plate 4 welded to the inner side of the second gray plate 2. The gap between the two first adjusting plates 3 allows the second adjusting plate 4 to slide in. A through hole is coaxially formed on the first adjusting plate 3 and the second adjusting plate 4.
[0027] The angle adjustment component includes a positioning sleeve 6 for connecting the second adjustment plate 4, a connecting rod 5 installed inside the positioning sleeve 6, and fixing components installed at both ends of the positioning sleeve 6 for fixing the position and angle of the connecting rod 5. A connecting structure for connecting the first connecting component is also installed on the connecting rod 5, and the connecting rod 5 can slide and rotate inside the positioning sleeve 6.
[0028] Specifically, both ends of the connecting rod 5 are provided with external threads, and both ends of the positioning sleeve 6 are respectively provided with internal threads. Through the connection of the external and internal threads, the connecting rod 5 can rotate within the positioning sleeve 6 and slide up and down while rotating. The fixing parts are the top nut 8 and the bottom nut 9 installed on the connecting rod 5 on the outer sides of both ends of the fixing sleeve. When it is necessary to rotate the connecting rod 5, the top nut 8 and the bottom nut 9 are turned outwards at both ends to loosen the connecting rod 5 and allow it to rotate. When the first gray plate 1 and the second gray plate 2 are respectively attached to the outer walls of the inside and outside corners, the top nut 8 and the bottom nut 9 are turned inwards at both ends until the top nut 8 and the bottom nut 9 abut against both ends of the positioning sleeve 6, thereby fixing the position and angle of the connecting rod 5.
[0029] like Figure 2 and Figure 3 As shown, in this embodiment, two sets of connecting structures are installed on the connecting rod 5. The connecting structure includes two first connecting plates 10 installed on the connecting rod 5. Limiting blocks 13 are integrally formed on both sides of the connecting rod 5. Each of the first connecting plates 10 has a connecting hole coaxially opened for the connecting rod 5 to pass through, and each of the first connecting plates 10 also has a limiting groove for the limiting block 13 to slide inside.
[0030] The positioning sleeve 6 has an exposed slot for the first connecting plate 10 to be exposed, and the first connecting plate 10 can rotate within the exposed slot. The first adjusting plate 3 also has a first connecting slot that communicates with the through hole and allows the first connecting plate 10 to extend into it. A second connecting plate 11 is welded to the outside of the positioning sleeve 6 between two adjacent first connecting plates 10 within the same set of connecting structures. The second adjusting plate 4 also has a second connecting slot that communicates with the through hole and allows the second connecting plate 11 to extend into it.
[0031] Furthermore, in this embodiment, both ends of the first connecting plate 10 located in the exposed slot are integrally formed with a closed T-shaped ring platform 12, and T-shaped ring grooves 16 are respectively opened on the inner walls of both ends of the exposed slot for the T-shaped ring platform 12 to be inserted and can slide inside.
[0032] Slots are formed on both sides of the first connecting slot of the first adjusting plate 3 and the second connecting slot of the second adjusting plate 4. Locking keys 14 are integrally formed on both sides of the first connecting plate 10 and the second connecting plate 11, corresponding to the slots. By inserting the locking keys 14 on the first connecting plate 10 and the second connecting plate 11 into the slots of the first adjusting plate 3 and the second adjusting plate 4, the connection and fixation between the first connecting plate 10 and the first adjusting plate 3, and between the second connecting plate 11 and the second adjusting plate 4 are achieved. Furthermore, limiting horizontal blocks 15 are integrally formed on both sides of the first connecting plate 10 and the second connecting plate 11. Locking keys 14 are respectively located at the two outer ends of the limiting horizontal blocks 15. Limiting horizontal grooves for the limiting horizontal blocks 15 to slide into are also correspondingly formed on the first adjusting plate 3 and the second adjusting plate 4. Slots are respectively formed at the two inner ends of the limiting horizontal grooves.
[0033] A corner plate is also welded to the inner side of the bottom end of the positioning sleeve 6, and the vertical section of the corner plate is a vertical grip 7.
[0034] When using this utility model, first install the first connecting plate 10 in the exposed slot, then insert the connecting rod 5, and pre-tighten the top nut 8 and bottom nut 9 at both ends of the connecting rod 5. Then, the first adjusting plate 3 of the first gray plate 1 is positioned and connected to the first connecting plate 10 through the snap-fit relationship between the snap-fit key 14 and the snap-fit slot. The second adjusting plate 4 of the second gray plate 2 is positioned and connected to the second connecting plate 11 through the snap-fit relationship between the snap-fit key 14 and the snap-fit slot. In this way, a complete corner puller is assembled.
[0035] Then rotate the connecting rod 5 to attach the inner walls of the first mortar board 1 and the second mortar board 2 to the two sides of the inside and outside corners respectively. Use this angle as the plastering construction angle. Then, under this angle, screw the top nut 8 and the bottom nut 9 inwards respectively until the top nut 8 and the bottom nut 9 abut against the two ends of the positioning sleeve 6 respectively. This completes the fixing of the connecting rod 5 and the angle fixing of the gap between the first mortar board 1 and the second mortar board 2. In the subsequent plastering construction process, the construction is carried out by holding the handle 7.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
