Description

Technical Field

[0001] This application relates to the field of building engineering, and in particular to a fastener. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] Currently, in the construction industry, temporary housing is needed to ensure temporary accommodation for people. Temporary housing is generally constructed using panels. During the construction of panel housing, when two adjacent panels are joined together, multiple construction workers are needed to support the panels to ensure their verticality and stability. Then, the two perpendicular panels are fixed or connected. The method of supporting the panels by construction workers to ensure stability is quite laborious, and manual support may cause the perpendicular panels to deviate in position. Utility Model Content

[0004] To address the problem that ensuring stability through manual support by construction workers is laborious and may lead to misalignment of perpendicular plates, this application provides a fastener.

[0005] The fastener provided in this application adopts the following technical solution:

[0006] The device includes an L-shaped connector, with fixed slots at both ends and an installation slot on the side of the fixed slot. A limit frame is fixedly installed inside the installation slot, and a movable abutment block is movably installed inside the limit frame. A connecting block is installed on the movable abutment block, and a push plate is connected to the connecting block by a first screw.

[0007] By adopting the above technical solution, the two ends of the push plate push the connecting blocks to move. At this time, the connecting blocks push the movable abutment block to move inside the limiting frame. When the movable abutment block moves, the limiting strip on it moves inside the limiting groove, which can ensure that the movable abutment block moves more smoothly. When the movable abutment block moves, its inner side gradually contacts the side of the wall panel. Through the continuous movement of the movable abutment block, the wall panel can be fixed.

[0008] Preferably, a threaded connector is installed in the middle of the push plate, and an installation hole is provided on the L-shaped connector. A rotating rod is rotatably installed inside the installation hole, and the rotating rod passes through the middle of the threaded connector.

[0009] By adopting the above technical solution, when the rotating rod rotates, the threaded connector can move along the rotating rod through the cooperation of the connecting thread and the threaded connector, and the threaded connector drives the push plate to move.

[0010] Preferably, the rotating rod has a connecting thread, the rotating rod is connected by a connecting thread and a threaded connector, and a knob is installed at one end of the rotating rod.

[0011] By adopting the above technical solution, the rotating rod is driven to rotate inside the mounting hole by the knob. When the rotating rod rotates, the threaded connector can move along the rotating rod by cooperating with the connecting thread and the threaded connector.

[0012] Preferably, there are four mounting slots, which are located in pairs on the outer sides of both ends of the L-shaped connector. The L-shaped connector has a protruding strip on the inner wall of the fixed slot, and the protruding strip and the movable abutment block are respectively located on both sides of the fixed slot and are arranged opposite to each other.

[0013] By adopting the above technical solution, force can be applied to the wall panel by the continuous movement of the moving abutment block, so that the other side of the wall panel gradually contacts the protrusion strip, thereby fixing the wall panel.

[0014] Preferably, the upper and lower inner sides of the limiting frame are provided with limiting grooves, and the upper and lower parts of the movable abutment block are provided with limiting strips. The width of the limiting strips is adapted to the width of the limiting grooves. The limiting strips are located inside the limiting grooves and can move inside the limiting grooves.

[0015] By adopting the above technical solution, when the movable abutment block moves, the limiting strip on it moves inside the limiting groove, which can ensure that the movement of the movable abutment block is more stable.

[0016] Preferably, a second screw is provided on the outer side of the corner of the L-shaped connector, and the L-shaped connector is connected to a fixed sheet metal part by the second screw.

[0017] By adopting the above technical solution, the entire structure is fixed to the column by fixing sheet metal parts, thus ensuring the stability of the entire structure.

[0018] Preferably, the fixed sheet metal part has a connecting groove, and the number of connecting grooves is multiple, which are evenly distributed on both sides of the fixed sheet metal part.

[0019] By adopting the above technical solution, fixing bolts are installed inside multiple slots to connect the fixed sheet metal parts and external devices, making the whole more stable.

[0020] Preferably, the inner side of the L-shaped connector is provided with reinforcing ribs, and one end surface of the movable abutment block is flush with the inner wall of the fixed groove.

[0021] By adopting the above technical solution, by making one end surface of the movable abutment block flush with the inner wall of the fixed groove, the side of the wall panel can be easily inserted into the interior of the fixed groove.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application pushes the connecting block to move by pushing the two ends of the push plate. The connecting block pushes the moving abutment block to move inside the limiting frame. When the moving abutment block moves, the limiting strip on it moves inside the limiting groove, which can ensure that the moving abutment block moves more smoothly. When the moving abutment block moves, its inner side gradually contacts the side of the wall panel. Through the continuous movement of the moving abutment block, force can be applied to the wall panel, so that the other side of the wall panel gradually contacts the protrusion strip, thereby fixing the wall panel.

[0024] 2. This application uses a knob to drive a rotating rod to rotate inside the mounting hole. When the rotating rod rotates, the connecting thread and threaded connector cooperate to move the threaded connector along the rotating rod. The threaded connector drives the push plate to move, and then the wall panel can be fixed, which facilitates the operation of the whole. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] This application discloses a fastener including an L-shaped connector 1. The L-shaped connector 1 has fixing slots 2 at both ends. An installation slot 3 is formed on the side of the fixing slots 2 on the L-shaped connector 1. A limiting frame 4 is fixedly installed inside the installation slot 3. A movable abutment block 5 is movably installed inside the limiting frame 4. A connecting block 6 is installed on the movable abutment block 5. A push plate 8 is connected to the connecting block 6 via a first screw 7. A threaded connector 9 is installed in the middle of the push plate 8. An installation hole 11 is formed on the L-shaped connector 1. A rotating rod 10 is rotatably installed inside the installation hole 11. The rotating rod 10 passes through the middle of the threaded connector 9. A connecting screw is formed on the rotating rod 10. The rotating rod 10 is connected to the threaded connector 9 via the connecting thread 12. A knob 13 is installed at one end of the rotating rod 10. The knob 13 drives the rotating rod 10 to rotate inside the mounting hole 11. When the rotating rod 10 rotates, the threaded connector 9 can move along the rotating rod 10 through the cooperation of the connecting thread 12 and the threaded connector 9. The threaded connector 9 drives the push plate 8 to move. The two ends of the push plate 8 push the connecting block 6 to move. At this time, the connecting block 6 pushes the moving abutment block 5 to move inside the limit frame 4. When the moving abutment block 5 moves, its inner side gradually contacts the side of the wall panel. Through the continuous movement of the moving abutment block 5, force can be applied to the wall panel.

[0033] Please refer to Figures 1 to 5 There are four mounting slots 3, which are located in pairs on the outer sides of both ends of the L-shaped connector 1. The L-shaped connector 1 has a protrusion 16 on the inner wall of the fixed slot 2. The protrusion 16 and the movable abutment block 5 are respectively located on both sides of the fixed slot 2 and are arranged opposite to each other. The upper and lower parts of the inner side of the limiting frame 4 have limiting slots 14. The upper and lower parts of the movable abutment block 5 are provided with limiting strips 15. The width of the limiting strip 15 is adapted to the width of the limiting slot 14. The limiting strip 15 is located inside the limiting slot 14 and can move inside the limiting slot 14. When the movable abutment block 5 moves, the limiting strip 15 on it moves inside the limiting slot 14, which can ensure that the movable abutment block 5 moves more smoothly.

[0034] Please refer to Figure 1 and Figure 2 A second screw 18 is provided on the outer side of the corner of the L-shaped connector 1. The L-shaped connector 1 is connected to a fixed sheet metal part 19 through the second screw 18. The fixed sheet metal part 19 has a connecting groove 20. There are multiple connecting grooves 20, which are evenly distributed on both sides of the fixed sheet metal part 19. A column is built at the connection of the wall panel. The whole is fixed to the column by the fixed sheet metal part 19, which can maintain the stability of the whole. Alternatively, this utility model can be installed after a wall panel is fixed. At this time, it is not necessary to build a column to ensure stability.

[0035] Please refer to Figure 1 and Figure 3 The inner side of the L-shaped connector 1 is provided with reinforcing ribs 17. One end surface of the movable abutment block 5 is flush with the inner wall of the fixed groove 2. By making one end surface of the movable abutment block 5 flush with the inner wall of the fixed groove 2, the side of the wall panel can easily enter the interior of the fixed groove 2.

[0036] The implementation principle of a fastener according to an embodiment of this application is as follows: In use, firstly, the side of a wall panel is moved into the interior of a fixing slot 2 on the L-shaped connector 1. Then, the knob 13 on the outside of the fixing slot 2 is rotated. The knob 13 drives the rotating rod 10 to rotate inside the mounting hole 11. When the rotating rod 10 rotates, it engages with the threaded connector 9 via the connecting thread 12, allowing the threaded connector 9 to move along the rotating rod 10. The threaded connector 9 drives the push plate 8 to move, and the two ends of the push plate 8 push the connecting block 6 to move. At this time, the connecting block 6 pushes and moves, abutting the block 5 within the limit... When the moving abutment block 5 moves, the limiting strip 15 on it moves inside the limiting groove 14, which can ensure that the moving abutment block 5 moves more smoothly. When the moving abutment block 5 moves, its inner side gradually contacts the side of the wall panel. Through the continuous movement of the moving abutment block 5, force can be applied to the wall panel, so that the other side of the wall panel gradually contacts the protrusion 16, thereby fixing the wall panel. Then repeat the above steps to fix another mutually perpendicular wall panel. Finally, a column is built at the connection of the wall panels, and the whole is fixed to the column by fixing sheet metal parts 19.

[0037] 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.
