Description

A type of fastener for installing building insulation and decorative panels Technical Field

[0001] This utility model relates to the field of installation fastener technology, and more specifically, to an installation fastener for building insulation and decorative panels. Background Technology

[0002] Building insulation and decorative panel installation fasteners are important components used to fix insulation and decorative panels. Their function is to firmly fix the insulation and decorative panels to the wall, preventing them from falling off due to their own weight, wind force, earthquakes and other external forces, thus ensuring the safety of the building and the insulation and decoration effect.

[0003] Currently, large corner brackets are typically installed at external corners to connect one end of two decorative panels. This not only enhances aesthetics but also improves the overall stability of the decorative panels. The structure consists of a main clip and two cover plates. In use, the user secures the main clip to the surfaces of the two decorative panels with several bolts, and then uses the two cover plates to conceal the bolts. Currently, the cover plates are typically secured to the main clip surface by inserting clips into slots; however, this method is prone to loosening after prolonged use.

[0004] Therefore, under the current circumstances, it is necessary to design a new type of building insulation and decorative panel installation fastener to solve the problem that the shielding panels at large external corners are prone to loosening after long-term use. Summary of the Invention

[0005] In view of this, the present invention proposes a fastener for installing building insulation and decorative panels, the specific technical solution of which is as follows:

[0006] A fastener for installing building insulation and decorative panels includes a corner plate and a shielding plate. The corner plate includes two mutually perpendicular and fixedly connected external corner plates. The two external corner plates are correspondingly attached to two decorative panels located on the inner side. An outwardly protruding L-shaped plate is integrally connected to the outer side of the intersection of the edges of the two external corner plates. Several mounting bolts are slidably inserted into each external corner plate. During installation, the front ends of the mounting bolts are screwed into the corresponding decorative panel and the wall in sequence. An installation groove is opened on the outer side wall of each of the two bent plates in the L-shaped plate. Two gaps are formed between the two external corner plates and the L-shaped plate. The two shielding plates are respectively adapted to be installed in the two gaps. At the same time, the corresponding side ends of the shielding plates are slidably inserted into the mounting grooves on the same side. The inner wall of the shielding plate is also connected to the surface of the mounting bolts on the inner side of the corresponding external corner plate.

[0007] Preferably, a fixing nut is screwed onto the corresponding thread of the mounting bolt. After the mounting bolt passes through the corner plate and is screwed into the corresponding decorative panel and wall, the fixing nut is rotated to press tightly against the outer wall of the corner plate, which can limit the fixing bolt and make the corner plate fit tightly against the inner decorative panel.

[0008] Preferably, the shielding plate is connected to the surface of the mounting bolt via a connecting unit. The connecting unit includes several annular notches on the inner wall of the shielding plate. Each fixing nut has an annular groove on its outer circumferential surface. After the shielding plate is slidably inserted into the corresponding mounting groove, the annular notch can simultaneously fit and slide onto the annular groove on the fixing nut at the corresponding position, and can conform to the inner wall of the annular groove.

[0009] Preferably, the corresponding side end of the baffle is restricted to the interior of the mounting groove by a limiting unit. The limiting unit includes a plug provided on the side end of the baffle. The plug is adapted to the inner cavity of the mounting groove, and limiting grooves are provided on the inner groove walls on both sides of the mounting groove. Abutment heads are provided on both sides of the plug. The abutment heads are made of elastic material. After the plug enters the mounting groove, the abutment heads on it are correspondingly engaged in the limiting grooves.

[0010] Preferably, both the limiting groove and the contact head are provided with a plurality of them.

[0011] Preferably, an L-shaped fixing piece is threaded onto the outer front end of all the mounting bolts, and during installation, the fixing piece is located between the decorative panel and the wall.

[0012] Preferably, the fixing piece is made of metal.

[0013] Compared with existing technologies, the building insulation and decorative panel installation fastener of this utility model has the following advantages:

[0014] 1. In this utility model, two opposing mounting grooves are opened on the L-shaped plate protruding from the surface of the corner plate. During use, the user attaches the two corner plates to the surfaces of the two decorative panels, then slides several mounting bolts into each corner plate, threading the front ends of the bolts into the corresponding decorative panel surfaces. Finally, the bolts are threaded into the wall, fixing the ends of the two decorative panels to the wall and the corner plate to the surfaces of the two decorative panels. Finally, a baffle plate is placed in each of the two openings formed on the corner plate to complete the operation. The side ends of the baffle plates slide into the mounting grooves on the same side of the L-shaped plate, and the inner walls of the two baffle plates are connected to several mounting bolts on the corresponding inner corner plates, further ensuring the stability of the installation after the two baffle plates are inserted into the corresponding mounting grooves.

[0015] 2. In this utility model, after the user slides the mounting bolt into and through the corner plate, the fixing nut that is threaded onto the surface of the mounting bolt's thread groove is rotated, and the fixing nut is pressed against the outer wall of the corner plate, thereby limiting the installation of the mounting bolt. Compared with the method of directly screwing the mounting bolt into the corner plate, this limiting method does not require drilling a threaded hole in the corner plate, thus avoiding the problem of the threaded hole being damaged during transportation and affecting normal use.

[0016] 3. In this utility model, while the side end of the baffle plate is slidably inserted into the corresponding mounting groove, several annular notches opened on the inner wall of the baffle plate will slide and fit onto the annular grooves on the corresponding fixing nuts, and fit against the inner wall of the several annular grooves, thereby realizing the connection limit between the baffle plate and the surface of the several fixing nuts. Ultimately, this ensures the stable limit of the two baffle plates in the two gaps of the corner plate, avoiding the problem of the baffle plates easily becoming loose after long-term use.

[0017] 4. In this utility model, an L-shaped fixing piece adapted to the shape of the corner plate is set on the front side of the corner plate. The fixing piece is made of metal. In use, the user first attaches the fixing piece to the corner of the wall, then attaches both decorative panels to the surface of the fixing piece, and then attaches the corner plate to the surface of the decorative panels. Several mounting bolts are then passed through the two corner plates and threaded into the two decorative panels, the fixing piece, and the wall. The significance of adding the fixing piece to this device is that installation quality issues with the decorative panels can lead to warping at the ends. By placing the fixing piece between the decorative panel and the wall, the ends of the decorative panel are clamped between the fixing piece and the corner plate, preventing warping.

[0028] Example:

[0029] This embodiment provides a fastener for installing building insulation and decorative panels, mainly used to solve the problem of loosening of the shielding panels at large external corners after long-term use, and provides the following technical solution, which will be explained in detail below with reference to Figures 1-5:

[0030] A fastener for installing building insulation and decorative panels includes a corner plate 1 and a shielding plate 2. The corner plate 1 includes two mutually perpendicular and fixedly connected external corner plates 3. The two external corner plates 3 are correspondingly attached to two decorative panels located on the inner side, and an outwardly protruding L-shaped plate 4 is integrally connected to the outer side of the intersection of the edges of the two external corner plates 3. Several mounting bolts 5 are slidably inserted on each external corner plate 3. During installation, the front ends of the mounting bolts 5 are screwed into the corresponding decorative panel and the wall in sequence. An installation groove 6 is opened on the outer side wall of each of the two bent plates in the L-shaped plate 4. Two gaps 7 are formed between the two external corner plates 3 and the L-shaped plate 4. The two shielding plates 2 are respectively adapted to be installed in the two gaps 7, and the corresponding side ends of the shielding plates 2 are slidably inserted into the mounting grooves 6 on the same side. The inner wall of the shielding plate 2 is also connected to the surface of the mounting bolts 5 on the corresponding internal external corner plate 3.

[0031] In use, the user attaches the two external corner plates 3 on the corner plate 1 to the surfaces of the two decorative panels. Then, several mounting bolts 5 are slidably inserted into the two external corner plates 3, with the front ends of each bolt threaded into the surface of the corresponding decorative panel. Finally, the bolts are threaded into the wall, fixing the ends of the two decorative panels to the wall and securing the corner plate 1 to the surfaces of the two decorative panels. Finally, a shielding plate 2 is placed in each of the two openings 7 formed on the corner plate 1 to complete the operation. The side end of the shielding plate 2 is slidably inserted into the mounting groove 6 on the same side of the L-shaped plate 4. The inner walls of the two shielding plates 2 are also connected to several mounting bolts 5 on the inner side of the corresponding external corner plates 3, further ensuring the stability of the installation after the two shielding plates 2 are inserted into the corresponding mounting grooves 6.

[0032] In a further specific embodiment, a fixing nut 8 is screwed onto the corresponding thread of the mounting bolt 5. After the mounting bolt 5 passes through the corner plate 3 and is screwed into the corresponding decorative panel and wall, the fixing nut 8 is rotated to press tightly against the outer wall of the corner plate 3, which can limit the mounting bolt 5 and make the corner plate 3 fit tightly against the inner decorative panel.

[0033] Since the mounting bolt 5 has a threaded groove on its surface, after the user slides the mounting bolt 5 into and through the corner plate 3, the fixing nut 8, which is threaded and fitted onto the threaded groove of the mounting bolt, can be rotated to make the fixing nut 8 abut against the outer wall of the corner plate 3, thereby limiting the installation of the mounting bolt 5. Compared with the method of directly screwing the mounting bolt 5 into the corner plate 3, this limiting method does not require the drilling of a threaded hole in the corner plate 3, thus avoiding the problem of the threaded hole being damaged during transportation and affecting normal use.

[0034] Furthermore, the shield 2 is connected to the surface of the mounting bolts 5 via a connecting unit. The connecting unit specifically includes several annular notches 9 on the inner wall of the shield. Each fixing nut 8 has an annular groove 10 on its outer circumference. In use, the user first slides the side end of the shield 2 into the corresponding mounting groove 6. At the same time, several annular notches 9 on the inner wall of the shield will slide and fit onto the annular grooves 10 on the corresponding fixing nuts 8, and fit against the inner wall of several annular grooves 10, thus achieving the connection between the shield 2 and the surfaces of several fixing nuts.

[0035] In a further specific embodiment, the corresponding side end of the baffle plate 2 is restricted to the interior of the mounting groove 6 by a limiting unit. The limiting unit includes a plug 11 provided on the side end of the baffle plate. The plug 11 is adapted to the inner cavity of the mounting groove 6, and limiting grooves 12 are provided on the inner groove walls on both sides of the mounting groove 6. The plug 11 is provided with abutment heads 13 on both sides. The abutment heads 13 are made of elastic material. After the plug 11 enters the mounting groove 6, the abutment heads 13 on it are correspondingly engaged in the limiting grooves 12.

[0036] In use, the user needs to slide the plugs 11 in the two baffles 2 into the inner walls of the two mounting slots 6 respectively (the mounting slots have cavities with the same shape as the plugs for fixing the plugs). At the same time, there are contact heads 13 made of elastic material on both sides of the two plugs 11. Therefore, after the plugs 11 are inserted into the mounting slots 6, the contact heads 13 on both sides can abut against the limiting slots 12 on the inner wall of the mounting slots, thereby limiting the two baffles 2 in the two mounting slots 6.

[0037] Furthermore, to ensure the limiting effect, several limiting grooves 12 and contact heads 13 are provided. In this embodiment, as shown in Figures 3 and 4, three limiting grooves 12 are parallel to each other on one side of the inner groove wall of the mounting groove 6, and correspondingly, three contact heads 13 are parallel to each other on one side of the plug 11.

[0038] In a further specific embodiment, as shown in Figures 1 and 2, an L-shaped fixing plate 14 is threaded onto the outer front end of all mounting bolts 5. During installation, the fixing plate 14 is located between the decorative panel and the wall. Furthermore, the fixing plate 14 is made of metal.

[0039] In this embodiment, an L-shaped fixing piece 14, made of metal, is installed on the front side of the corner plate 1. The user first attaches the fixing piece 14 to the corner of the wall, then attaches both decorative panels to the surface of the fixing piece 14, and then attaches the corner plate 1 to the surface of the decorative panels. Several mounting bolts 5 are then threaded through the two corner plates 3 and inserted into the two decorative panels, the fixing piece 14, and the wall. The significance of adding the fixing piece 14 in this device is that installation quality issues with the decorative panels can lead to warping at the ends. By placing the fixing piece 14 between the decorative panel and the wall, the ends of the decorative panel are clamped between the fixing piece 14 and the corner plate 1 (as shown in Figure 5, where A represents the wall and B represents the decorative panel), thus preventing warping.

[0040] The working process of this utility model is as follows:

[0041] First, the user attaches the fixing piece 14 to the corner of the wall, then attaches both decorative panels to the surface of the fixing piece 14, and then attaches the corner plate 1 to the surface of the decorative panel. Then, several mounting bolts 5 are passed through the two corner plates 3 and then threaded into the two decorative panels, the fixing piece 14 and the wall respectively. This will fix the two decorative panels to the wall and install the corner plate 1 at both ends of the two decorative panels. The ends of the decorative panels are sandwiched between the fixing piece 14 and the corner plate 1.

[0042] Secondly, the user needs to slide the plugs 11 of the two shields 2 into the inner walls of the corresponding two mounting slots 6. At the same time, several elastic contact heads 13 on both sides of the plugs will hook into the limiting grooves 12 in the inner walls of the two mounting slots 6. That is, the two shields 2 are limited in the two mounting slots 6 through friction and locking. While the side ends of the two shields 2 are slid into the corresponding mounting slots 6, several annular notches 9 on the inner walls of the shields will slide and fit into the annular grooves 10 on the corresponding fixing nuts 8, and fit against the inner walls of the annular grooves 10, realizing the connection and limitation between the shields 2 and the surfaces of the fixing nuts. Through the connection and cooperation of the plugs 11, annular notches 9 and other structures, this device ultimately ensures the stable limitation of the two shields 2 in the two empty spaces 7 of the corner plate 1, avoiding the problem of the shields 2 becoming loose after long-term use.

[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
