Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a tool for installing and returning a decorative panel. Background Art

[0002] Decorative panels are sheet-like materials used for interior and exterior decoration, often applied to surfaces such as walls, ceilings, and furniture. They can be used to enhance the aesthetics of a space and are available in a variety of materials, styles, and colors, including wood, metal, plastic, fiberboard, and decorative panels with single-sided decorative effects.

[0003] With the continuous development of the construction industry, prefabricated buildings are gradually replacing the original building forms. Prefabricated door frames are a module in prefabricated buildings. During construction, it is necessary to fill the gaps in the door frames with foaming agent. However, construction workers have found that prefabricated door frames often expand due to the expansion of the filling foaming agent, causing the door frames to open and the flatness to decrease, thus affecting the visual quality acceptance. In order to improve the comfort and convenience of occupancy, decorative panels need to be installed on the outside of the wall during the construction process. Most panel fixing structures are aimed at the fixed relationship between the wall and the panel, but there are fewer improvements for holes in the wall such as door openings, door frames, window frames, door frames, etc., and they are basically bonded on site, and then supported by wood. This not only fails to guarantee the fitting quality of the decorative panels, but also affects the flatness requirements of the decorative panels, affecting the later quality and appearance.

[0004] The Chinese patent application number "CN202322098710.X" discloses an adjustable door frame support leveler, which includes a diamond-shaped bracket, which includes four unit rods, and the unit rods are hingedly connected end to end. The diamond-shaped bracket has a hydraulic rod installed between two opposing inner corners of the diamond bracket. The unit rods are also vertically provided with support rods for supporting the door frame. The end of the support rod away from the diamond bracket is provided with a rubber pad for supporting the door frame. The unit rods are also provided with a bubble level for measuring the flatness of the door frame. This application has the effect of fixing the door frame and improving the problem of door frame deformation during the filling process of the foaming agent.

[0005] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0006] Installation is cumbersome and has poor stability: when installing door frames or decorative panels, glue, foaming agent or cement mortar is needed to seal the seams and bond them, and the mainstream support method is still to use wooden support rods for support (such as application number: CN201320555076.1). Since the wooden support rods themselves cannot be adjusted, and for holes of different shapes and sizes such as door openings and window openings, wooden support rods of corresponding sizes must be made respectively, which results in a large workload on site, waste of time, poor stability, especially excessive demand for wood, waste of materials, and high production time and cost; the existing solutions mainly use adjustable screws instead of wooden support rods, and adjust the length of the screws to suit different needs, but the existing Some adjustable screws mostly require the use of tools to adjust and lock (for example, the patent application number is: "CN202322098710.X", the limiter is a bolt, which needs to be rotated with the help of a wrench or other tools. In addition, since the sleeve cannot rotate and there is no structure on the surface of the screw that can be used for direct clamping, the extension and retraction of the screw requires the use of tools or the construction worker to rotate it by hand), which makes the installation or subsequent adjustments very cumbersome. In addition, due to the complex construction site environment, it is inconvenient for construction workers to carry equipment that is too large or too heavy. Moreover, the biggest reason for whether a device can be effectively used on the construction site is whether the device is easy to use. For this reason, we propose a decorative panel installation and top-back tool. Utility Model Content

[0007] (1) Technical problems solved

[0008] In response to the deficiencies in the prior art, the present invention provides a decorative panel installation and retraction tool. Since a threaded ring with a handle is used as an adjustment tool for the long screw, the extension and retraction of the long screw can be adjusted by manually rotating the threaded ring. In addition, after the adjustment is completed, the handle can be folded into the embedded groove on the surface of the connecting piece, thereby indirectly locking the position between the threaded ring and the connecting piece, thereby maintaining the stability of the extension of the long screw. Therefore, the present invention effectively solves the technical problem that the support tools used in the existing door frames or decorative panels during installation are cumbersome to install and have poor stability, thereby realizing manual adjustment of the extension and retraction of the long screw, and locking it after the adjustment is completed, thereby improving the stability after adjustment, preventing the adjusted long screw from shaking or deviating, and solving the technical problem that the support tools used in the existing door frames or decorative panels during installation are cumbersome to install and have poor stability.

[0009] (2) Technical solution

[0010] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] A decorative panel installation and top-returning tool, the top-returning tool comprising:

[0012] The top-returning tool includes a plurality of interconnected connecting parts. The connecting parts can be connected by "tail" relative to each other, or by installing two "vertical" connecting parts on them. Then, the channel steel plate is installed on the docking plate outside the connecting parts. At this time, the door or window opening can be supported and the decorative panel on the inner wall of the door opening can be squeezed to maintain the fit between the decorative panel and the inner wall of the door opening. After that, a foaming agent or glue can be poured into the gap between the wall and the decorative panel, so that the decorative panel and the wall form a whole.

[0013] The support member includes a long screw rod inserted into the interior of the connector, and the long screw rod is threadedly connected to the threaded ring at the end of the connector. When the threaded ring rotates, the long screw rod can be telescopically moved along the extension direction of the connector.

[0014] Preferably, the long screw is movable and must rotate relative to the threaded ring, while the threaded ring can rotate under the drive of the handle. Therefore, it is necessary to keep the long screw from rotating. For this purpose, we install a docking plate and a sliding block at both ends of the long screw. The end with the sliding block is inserted into the interior of the connecting piece (and the sliding block can slide inside the connecting piece) and corresponds to the shape of the inner wall of the connecting piece. In this way, the long screw cannot rotate relative to the connecting piece, but can only perform telescopic movement; the docking plate at the other end fits with the groove on the surface of the channel steel plate, and can be connected by welding or bolts. Since the surface of the docking plate is rough, it can also be fitted with the groove of the connecting channel steel plate by extrusion.

[0015] Preferably, the threaded ring is connected to the bearing at the end of the square steel tube, and a cylindrical docking tube is connected to one side of the threaded ring, and this docking tube is inserted into the interior of the connector and connected to the bearing at the end of the connector. The long screw passes through the center of the bearing, and the threaded ring is threadedly connected to the long screw inside the connector, so when the threaded ring rotates, it can drive the long screw to perform telescopic movement.

[0016] Preferably, two handles are symmetrically provided on the surface of the threaded ring, and the handles are hinged to the threaded ring;

[0017] The end of the handle is connected to a rectangular connecting block, and the handle is hinged to the threaded ring through the connecting block. When the handle and the long screw are perpendicular to each other, the connecting block fits against the outer wall of the threaded ring.

[0018] Preferably, embedding grooves are provided on the outer walls on both sides of the connecting piece, and the embedding grooves correspond to the handles on the threaded ring, which can be received in the embedding grooves by rotating the handles, and by pulling the handles located in the embedding grooves outwards, since the connecting block at the end of the handles is connected to the threaded rings through a rotating shaft, the handles can be pulled outwards during rotation; after use, the handles are made to correspond to the embedding grooves on both sides of the connecting piece, and then the handles can be rotated into the embedding grooves until the handles are completely inserted into the embedding grooves, at this time, the threaded ring connected to the handles cannot rotate relative to the connecting piece, and since the extension and shortening of the long screw rod requires the relative rotation of the threaded ring and the connecting piece, when the threaded ring cannot rotate, the length of the long screw rod is locked, thereby maintaining the state of the long screw rod and preventing it from shaking or offsetting during use.

[0019] Preferably, the surface of the connecting member and the end away from the support member are provided with a plurality of symmetrically arranged threaded holes. When the two connecting members need to be connected to each other, the "tails" of the two connecting members are first docked relative to each other. At this time, the threaded holes at the ends of the two connecting members correspond to each other, and then bolts are passed through the threaded holes (the inner wall of the threaded hole is provided with threads that can be directly screwed with the bolts) to connect the two adjacent connecting members together.

[0020] Preferably, a reserved groove is provided on the surface of the connecting member, and the reserved groove is close to an end of the connecting member away from the supporting member, and the reserved groove corresponds to the threaded hole at the end of the connecting member.

[0021] Preferably, two adjacent connecting members are connected by a hinge.

[0022] (3) Beneficial effects

[0023] 1. Since a threaded ring with a handle is used as an adjustment tool for the long screw, the extension and retraction of the long screw can be adjusted by manually rotating the threaded ring. In addition, after the adjustment is completed, the handle can be folded into the embedded groove on the surface of the connecting piece, thereby indirectly locking the position between the threaded ring and the connecting piece, thereby maintaining the stability of the extension of the long screw. Therefore, it effectively solves the technical problems of cumbersome installation and poor stability of the supporting tools used in the installation of existing door frames or decorative panels, thereby realizing manual adjustment of the extension and retraction of the long screw, and can also be locked after the adjustment is completed, thereby improving the stability after adjustment and preventing the adjusted long screw from shaking or deviation.

[0024] 2. Since a connector with a threaded hole is used as the carrier of the support, the two connectors can be assembled together by bolts to adapt to different shape requirements. At the same time, the volume of the device can be reduced when not in use or transported. In addition, two adjacent connectors can be connected together by hinges, thereby avoiding the need for tools for installation and combination, thereby improving the convenience of using the device.

[0039] The embodiment of the present application solves the technical problem of cumbersome installation and poor stability of the supporting tools used in the installation of existing door frames or decorative panels by providing a decorative panel installation and returning tool. Since a threaded ring with a handle is used as an adjustment tool for the long screw, the extension and retraction of the long screw can be adjusted by manually rotating the threaded ring. In addition, after the adjustment is completed, the handle can be folded into the embedding groove on the surface of the connecting part, thereby indirectly locking the position between the threaded ring and the connecting part, thereby maintaining the stability of the elongation of the long screw, thereby realizing manual adjustment of the extension and retraction of the long screw, and it can also be locked after the adjustment is completed, thereby improving the stability after adjustment and preventing the adjusted long screw from shaking or deviation.

[0040] Example 1: The technical solution in the embodiment of the present application is to solve the technical problem that the support tools used in the installation of existing door frames or decorative panels are cumbersome to install and have poor stability. The overall idea is as follows:

[0041] In view of the problems existing in the prior art, the utility model provides a decorative panel installation and top-returning tool, which includes a plurality of interconnected connecting members 1, such as Figure 2 As shown, the connectors 1 can be connected in a manner that the "tails" are opposite to each other (such as Figure 2 The structure below), or by installing a "vertical" connection member 1 (such as Figure 2 The channel steel plate 3 is then installed on the butt joint plate 22 outside the connector 1 to form a Figure 1 The structure shown in the figure can now support the door opening or window opening and squeeze the decorative panel on the inner wall of the door opening, such as Figure 9 As shown, this can maintain the fit between the decorative panel and the inner wall of the door opening, and then the foaming agent or glue can be poured into the gap between the wall and the decorative panel, so that the decorative panel and the wall form a whole.

[0042] In order to be applicable to different situations, such as door openings or window openings of different sizes, it is necessary to adjust the size of the device to suit different needs, as follows;

[0043] like Figure 4 As shown, follow the order from top to bottom, such as Figure 4 As shown in (a), the first step is to pull the handle 25 located in the embedded groove outward. Since the connecting block 26 at the end of the handle 25 is connected to the threaded ring 24 through the rotating shaft, the handle 25 can be pulled outward when rotating to form a Figure 4 (b) is shown in the structure.

[0044] The second step is Figure 4As shown in (b), by manually rotating the handle 25, the handle 25 drives the threaded ring 24 to rotate. Since the threaded ring 24 is connected to the bearing 13 at the end of the square steel tube 11 (as shown in FIG. Figure 5 and Figure 6 As shown, one side of the threaded ring 24 is connected to a cylindrical docking tube 27, and this docking tube 27 is inserted into the interior of the connector 1 and connected to the end bearing 13 of the connector 1, and the long screw 21 passes through the center of the bearing 13), and the threaded ring 24 is threadedly connected to the long screw 21 inside the connector 1, so when the threaded ring 24 rotates, it can drive the long screw 21 to perform telescopic movement.

[0045] In the above manner, the degree of elongation of the long screw 21 can be adjusted to adapt to the size requirements of different door and window holes. After adjustment, the handle 25 corresponds to the embedding grooves on both sides of the connector 1. Then, the handle 25 can be rotated into the embedding groove until the handle 25 is completely inserted into the embedding groove. At this time, the threaded ring 24 connected to the handle 25 cannot rotate relative to the connector 1. Since the elongation and shortening of the long screw 21 require the relative rotation of the threaded ring 24 and the connector 1, when the threaded ring 24 cannot rotate, the length of the long screw 21 is locked, thereby maintaining the state of the long screw 21 and preventing it from shaking or offsetting during use.

[0046] In addition, it was found during use that when the long screw 21 moves, it must rotate relative to the threaded ring 24, and the threaded ring 24 can rotate under the drive of the handle 25, so it is necessary to keep the long screw 21 from rotating. For this reason, we install a docking plate 22 and a sliding block 23 at both ends of the long screw 21. The end with the sliding block 23 is inserted into the interior of the connector 1 (and the sliding block 23 can slide inside the connector 1) and corresponds to the shape of the inner wall of the connector 1. In this way, the long screw 21 cannot rotate relative to the connector 1, but can only perform telescopic movement; the docking plate 22 at the other end fits with the groove on the surface of the channel steel plate 3, and can be connected by welding or bolts. Since the surface of the docking plate 22 is rough, it can also be fitted with the groove of the connecting channel steel plate 3 by extrusion.

[0047] The connecting block 26 at the end of the handle 25 is designed to be rectangular, and when the handle 25 and the long screw 21 are perpendicular to each other, the connecting block 26 fits with the outer wall of the threaded ring 24, as shown in FIG. Figure 6 As shown, the handle 25 cannot continue to rotate outward, thereby maintaining the stability of the handle 25 during rotation.

[0048] In the specific implementation process, Figure 1 Place the device shown in the door opening, then follow the steps below. Figure 4As shown in the steps, first pull the handle 25 located in the embedded groove outward. Since the connecting block 26 at the end of the handle 25 is connected to the threaded ring 24 through the rotating shaft, the handle 25 can be pulled outward when rotating to form a Figure 4 (b) shows the structure. The handle 25 is then manually rotated, causing the handle 25 to rotate the threaded ring 24. Because the threaded ring 24 is connected to the bearing 13 at the end of the square steel tube 11 and is threadedly connected to the long screw 21 inside the connector 1, the rotation of the threaded ring 24 can drive the long screw 21 to extend and retract.

[0049] After the long screw 21 is adjusted, the handle 25 is rotated to a position corresponding to the embedding grooves on both sides of the connector 1, and then the handle 25 can be rotated into the embedding groove by rotating until the handle 25 is completely inserted into the embedding groove. At this time, the threaded ring 24 connected to the handle 25 cannot rotate relative to the connector 1. Since the extension and shortening of the long screw 21 require the relative rotation of the threaded ring 24 and the connector 1, when the threaded ring 24 cannot rotate, the length of the long screw 21 is locked, thereby maintaining the state of the long screw 21 to prevent it from shaking or deflecting during use. Figure 3 shown.

[0050] Example 2: Based on Example 1, this embodiment of the present application provides a structure that facilitates assembly and disassembly of connectors. The overall concept is as follows:

[0051] There are multiple symmetrically arranged threaded holes on the surface of the connecting member 1 and on the end away from the supporting member 2, such as Figure 4 As shown, when two connectors 1 need to be docked with each other, first dock the "tails" of the two connectors 1 relative to each other (as shown in FIG. Figure 2 The threaded holes at the ends of the two connectors 1 correspond to each other, and then bolts are passed through the threaded holes (the inner walls of the threaded holes are provided with threads that can be directly screwed with the bolts) to connect the two adjacent connectors 1 together.

[0052] For the installation of two connecting pieces 1 perpendicular to each other, the threaded hole at the end of one connecting piece 1 is matched with the threaded hole on the surface of the other connecting piece 1, such as Figure 3 As shown, it is then connected to the threaded hole by bolts.

[0053] In order to facilitate the rotation of the bolt, a reserved groove 12 is opened on the surface of the connector 1, and this reserved groove 12 is close to the end of the connector 1 away from the support 2, and the reserved groove 12 corresponds to the threaded hole at the end of the connector 1. Figure 5 shown.

[0054] Example 3: Based on Example 1, this embodiment of the present application is a structure that can facilitate the assembly and disassembly of the connector, and is different from Example 2. The overall idea is as follows:

[0055] Two adjacent connecting members 1 are connected by hinges, such as Figure 8 When storing as shown, follow the Figure 8 As shown, the retraction and extension are performed from top to bottom. First, the vertically placed connector 1 is rotated to both sides, as shown in FIG. Figure 8 (a) to Figure 8 As shown in (b), the originally vertically placed connecting piece 1 is now fitted with the horizontally placed connecting piece 1. Figure 8 As shown in (b), the two horizontally arranged connecting members 1 are then folded toward the center by rotation, as shown in FIG. Figure 8 (b) to Figure 8 (c) until the two horizontally arranged connecting members 1 are attached as shown. Figure 8 As shown in (c), the folding is completed.

[0056] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
