Description

Technical Field

[0001] This application relates to the technical field of interior decoration and construction, and in particular to a keel structure for fine decoration. Background Technology

[0002] A keel is a building material used to support shapes and fix structures. It is widely used in hotels, passenger stations, train stations, theaters, shopping malls, factories, office buildings, renovations of old buildings, interior decoration, and other places. A keel serves as the framework and base material for decoration and is used very commonly.

[0003] There are many types of keels. When installing a suspended ceiling, users need to select a ceiling keel. A ceiling keel includes a main keel, a secondary keel, threaded rods, and expansion tubes. The top of the main keel has a fixing hole. One end of the threaded rod passes through the fixing hole and is fixed to the main keel with a nut. The expansion tube is fixed to the other end of the threaded rod with a taper and a nut. Then, the expansion tube is fixed to the ceiling to achieve the fixed installation of the main keel. The side of the main keel is provided with a clamping plate, and the secondary keel is clamped between the clamping plates to complete the installation of the ceiling keel.

[0004] Currently, different diameter threaded rods are needed to fix the main keel for different installation strengths. However, since the inner diameter of the fixing hole cannot be adjusted, users need to frequently replace different models of main keel, which is inconvenient for users to carry out ceiling construction. Utility Model Content

[0005] To facilitate ceiling construction, this application provides a keel structure for interior decoration.

[0006] The technical solution for a keel structure used in interior decoration provided in this application is as follows:

[0007] A keel structure for interior decoration includes a main keel, a secondary keel connected to the main keel, a lead screw detachably connected to the main keel, an expansion tube detachably connected to the end of the lead screw, and an adjusting plate detachably connected to the main keel. The top surface of the main keel has multiple fixing holes. The expansion tube is fixedly connected to one end of the lead screw by a taper and a nut. The other end of the lead screw passes through the fixing holes and is fixedly connected to the main keel by two nuts. The side surface of the main keel has multiple clamping plates spaced apart, forming a locking slot between two adjacent clamping plates. The secondary keel is a U-shaped keel. The adjusting plate has adjusting holes with an inner diameter smaller than the inner diameter of the fixing holes, and the adjusting holes and fixing holes are coaxial.

[0008] By adopting the above technical solution, when users need to replace different models of lead screws according to working conditions, the adjustment plate is installed on the main keel. At this time, since the inner diameter of the adjustment hole is smaller than the inner diameter of the fixing hole, the lead screw with a smaller diameter can pass through the fixing hole, and through the adjustment hole, the lead screw can be fixed at the main keel by the adjustment plate. Users do not need to carry multiple models of main keels at all times, which facilitates the user's ceiling construction.

[0009] Optionally, the clamping plate is detachably connected to the main keel. The clamping plate includes a fixed shell, an extension plate connected to the fixed shell, and a fixing bolt threaded to the main keel. The bottom of the fixed shell is clamped to the secondary keel. Each clamping plate includes two fixed shells. The extension plate is slidably connected between the two fixed shells. The two fixed shells are close to or far from each other. The extension plate is detachably connected to the two fixed shells by the fixing bolt. Both the fixed shell and the extension plate are detachably connected to the main keel by the fixing bolt.

[0010] By adopting the above technical solution, users can interlock the main keel and the secondary keel with the clamping plate, thus achieving a stable connection between the main keel and the secondary keel. When users select secondary keels of different widths according to the actual installation conditions, they can adjust the distance between the two fixed shells and fix the relative positions of the two fixed shells with the extension plate, thereby achieving the purpose of adjusting the overall length of the clamping plate. This adapts to the installation of secondary keels of different widths, making it convenient for users to carry out ceiling construction.

[0011] Optionally, the side wall of the main keel is provided with multiple snap-fit ​​holes, and the surface of the fixing shell and the surface of the extension plate are also provided with snap-fit ​​holes. The snap-fit ​​holes are evenly arranged along the length direction of the main keel. The snap-fit ​​holes on the clamping plate correspond to each other, and the snap-fit ​​holes on the clamping plate and the snap-fit ​​holes on the main keel correspond to each other. The inner diameter of the snap-fit ​​hole is provided with internal thread, and the fixing bolt passes through the clamping plate and is threaded to the snap-fit ​​hole on the main keel.

[0012] By adopting the above technical solution, when the user passes the fixing bolt through the clamping plate and threaded it into the clamping hole on the main keel, a stable connection between the clamping plate and the main keel is achieved. At the same time, a stable connection between the fixing shell and the extension plate is achieved, making the installation between the main keel and the secondary keel more stable and improving the safety of the ceiling.

[0013] Optionally, the adjusting plate has mounting holes at both ends, and the fixing hole has bearing holes on both sides. The mounting holes and the bearing holes are directly opposite each other. The inner diameter of the mounting hole is provided with an internal thread. The adjusting plate is provided with an adjusting bolt. The adjusting bolt passes through the bearing hole and is threaded to the mounting hole.

[0014] By adopting the above technical solution, a stable connection between the adjusting plate and the main keel can be achieved.

[0015] Optionally, the top and bottom of the side wall of the fixed shell are provided with snap-fit ​​holes, the top and bottom of the side wall of the extension plate are provided with snap-fit ​​holes, and each snap-fit ​​plate is provided with four fixing bolts, which are located at the four corners of the snap-fit ​​plate.

[0016] By adopting the above technical solution, the number of fixing points of the extension plate is increased, making the fixing of the extension plate more stable.

[0017] Optionally, the interior of the fixed shell is provided with a sliding groove, and the sliding grooves on the two fixed shells are directly opposite each other. The two ends of the extension plate are respectively slidably connected to the sliding grooves of the two directly opposite fixed shells.

[0018] By adopting the above technical solution, the sliding groove limits the extension plate, making the installation of the extension plate more stable.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The adjustable plate in this application enables the main keel to connect to different types of threaded rods, eliminating the need for users to prepare multiple types of main keels and improving the convenience of ceiling construction.

[0021] The fixed shell and extension plate in this application can adjust the length of the clamping plate according to different models of secondary keel, thereby improving the applicability of this application and the convenience of ceiling construction. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0028] Currently, in order to facilitate ceiling construction, this application proposes a keel structure for interior decoration.

[0029] This application discloses a keel structure for interior decoration. (Refer to...) Figure 1 and Figure 2 A keel structure for interior decoration includes a main keel 1, a secondary keel 2 connected to the main keel 1, a lead screw 3 detachably connected to the main keel 1, an expansion tube 4 detachably connected to the end of the lead screw 3, and an adjusting plate 5 detachably connected to the main keel 1. The top surface of the main keel 1 is provided with multiple fixing holes 11. The expansion tube 4 is fixedly connected to one end of the lead screw 3 by a screw and a nut. The other end of the lead screw 3 passes through the fixing hole 11 and is fixedly connected to the main keel 1 by two nuts. The side of the main keel 1 is provided with multiple clamping plates 6. The clamping plates 6 are detachably connected to the main keel 1. The clamping plates 6 are spaced apart, and a bayonet is formed between two adjacent clamping plates 6. The secondary keel 2 is a U-shaped keel. The main keel 1 is clamped to the secondary keel 2 by the clamping plates 6. The adjusting plate 5 is provided with an adjusting hole 51. The inner diameter of the adjusting hole 51 is smaller than the inner diameter of the fixing hole 11. The adjusting hole 51 and the fixing hole 11 are coaxial. When users need to replace different models of lead screws 3 according to working conditions, the adjustment plate 5 is installed on the main keel 1. At this time, since the inner diameter of the adjustment hole 51 is smaller than the inner diameter of the fixing hole 11, the lead screw 3 with a smaller diameter can pass through the fixing hole 11. And through the adjustment hole 51, the lead screw 3 can be fixed at the main keel 1 by the adjustment plate 5. Users do not need to carry multiple models of main keels 1 at all times, which is convenient for users to carry ceiling construction.

[0030] Reference Figure 1 and Figure 2 The adjusting plate 5 has mounting holes 53 at both ends, and bearing holes 12 on both sides of the fixing hole 11. The mounting holes 53 and bearing holes 12 are directly opposite each other. The inner diameter of the mounting hole 53 is provided with internal threads. The adjusting plate 5 is provided with adjusting bolts 52. The adjusting bolts 52 pass through the bearing holes 12 and are threaded into the mounting holes 53, thereby achieving a stable connection between the adjusting plate 5 and the main keel 1. In other embodiments of this application, the inner diameter of the bearing holes 12 can also be provided with internal threads, making the connection of the adjusting plate 5 more stable and improving the connection stability of the main keel 1.

[0031] Furthermore, refer to Figure 3 and Figure 4The clamping plate 6 includes a fixed shell 61, an extension plate 62 connected to the fixed shell 61, and a fixing bolt 63 threaded to the main keel 1. Each clamping plate 6 includes two fixed shells 61. The bottom of the fixed shell 61 is clamped to the secondary keel 2 to achieve the clamping purpose between the clamping plate 6 and the secondary keel 2, and to achieve the clamping purpose between the main keel 1 and the secondary keel 2. The fixed shell 61 is provided with a sliding groove 611 inside. The sliding grooves 611 on the two fixed shells 61 are directly opposite each other. The two ends of the extension plate 62 are respectively slidably connected to the sliding grooves 611 of the two directly opposite fixed shells 61, so that the extension plate 62 is slidably connected between the two fixed shells 61, and the two fixed shells 61 can move closer or further apart, so that the length of the clamping plate 6 can be adjusted and changed. At the same time, the sliding groove 611 limits the extension plate 62, so that the installation of the extension plate 62 is more stable.

[0032] Furthermore, the sidewall of the main keel 1 is provided with multiple snap-fit ​​holes 7. Two rows of snap-fit ​​holes 7 are provided on the surface of the fixing shell 61 and the surface of the extension plate 62. The two rows of snap-fit ​​holes 7 are located at the top and bottom of the sidewall of the fixing shell 61, and at the top and bottom of the sidewall of the extension plate 62, respectively. The snap-fit ​​holes 7 are evenly distributed along the length of the main keel 1. The snap-fit ​​holes 7 on the snap-fit ​​plate 6 correspond to each other, and the snap-fit ​​holes 7 on the snap-fit ​​plate 6 and the snap-fit ​​holes 7 on the main keel 1 correspond to each other. The inner diameter of the snap-fit ​​holes 7 is set as follows: With internal threads, the fixing bolt 63 passes through the clamping plate 6 and is threaded to the snap-fit ​​hole 7 on the main keel 1. After the fixing bolt 63 passes through and is threaded to the snap-fit ​​hole 7, the extension plate 62 is detachably connected to the two fixing shells 61 by the fixing bolt 63. This achieves the purpose that both the fixing shell 61 and the extension plate 62 are detachably connected to the main keel 1 by the fixing bolt 63, making the connection between the clamping plate 6 and the main keel 1 more stable and improving the connection stability between the main keel 1 and the secondary keel 2.

[0033] Furthermore, the fixed shell 61 and the extension plate 62 have double rows of snap-fit ​​holes 7, and each snap-fit ​​plate 6 is equipped with four fixing bolts 63, located at the four corners of the snap-fit ​​plate 6. This increases the fixing points of the extension plate 62, making its fixation more stable. When the user passes the fixing bolts 63 through the snap-fit ​​holes 7 on the main keel 1 and threads them into the snap-fit ​​holes 7, a stable connection is achieved between the fixed shell 61 and the extension plate 62, making the installation between the main keel 1 and the secondary keel 2 more stable and improving the safety of the suspended ceiling.

[0034] When a user selects a secondary keel 2 of different widths based on actual installation conditions, the user can adjust the distance between the two fixing shells 61 and fix the relative positions of the two fixing shells 61 using the extension plate 62. This allows for adjustment of the overall length of the clamping plate 6, accommodating the installation of secondary keels 2 of different widths and facilitating ceiling construction. When the width of the secondary keel 2 is small, the user can use the two fixing shells 61 on both sides of the clamping plate 6 to clamp the secondary keel 2 inside, thus fixing it. When the width of the secondary keel 2 is large, the user can adjust the length of the extension plate 62 inside the fixing shells 61, adjusting the distance between the two fixing shells 61 to accommodate the width of the secondary keel 2 and fix different models of secondary keels 2, improving the applicability of this application. When the width of the secondary keel 2 exceeds the maximum length of the clamping plate 6, the user can fix two fixing shells 61 on each side of the secondary keel 2 to secure it, further improving the applicability of this application.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
