Abstract
Description
Technical Field
[0001] This application relates to the field of reinforcement nail technology, and more specifically, to a special reinforcement nail for preventing loosening of exterior walls. Background Technology
[0002] Exterior wall insulation boards are boards applied to the exterior of building walls for insulation. They are made from polystyrene resin and other raw materials and polymers through extrusion. They have moisture-proof and waterproof properties, reducing the thickness of the building's external envelope and thus increasing usable indoor space. In current technology, exterior wall insulation boards are fixed to the exterior wall using reinforcing nails during construction. To ensure a secure installation, expansion bolts are typically used. The expansion tubes of the bolts are inserted into pre-drilled holes. However, since drilling generally involves a gradual decrease in hole diameter from the opening to the depth of the hole, if the bolt slips when it is deep within the hole, the increasing hole diameter makes it impossible to continue securing it, causing it to fall off. Removing the expansion bolts is also quite difficult.
[0003] Therefore, a special type of reinforcing nail for preventing loosening of exterior walls is needed to solve the above problems. Utility Model Content
[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a special reinforcement nail for preventing loosening of exterior walls, comprising: a nail head and a nail body; a hexagonal hole on the nail head; an inner hole in the nail body; a screw rotatably connected within the inner hole; one end of the screw fixedly connected to a rotating head; a rotating hole on the rotating head; circumferentially distributed locking grooves on the nail body; a locking strip rotatably connected within the locking grooves; a threaded block slidably connected within the inner hole; the threaded block threadedly engaging with the screw; a hinged rod connected to the locking strip bracket of the threaded block; one end of the hinged rod hinged to the threaded block; and the other end of the hinged rod hinged to the locking strip.
[0006] With the screw and locking strip in place, after the nail body is inserted into the outer wall through the hexagonal hole, the screw is rotated through the rotating hole, which in turn causes the threaded block to move, causing the locking strip to deflect and fix the nail body in place, preventing it from loosening.
[0007] Furthermore, the hinged rod includes a sleeve and a connecting rod. The sleeve is fitted onto the connecting rod and slides with the connecting rod, allowing the hinged rod to extend and retract as a whole. A spring connects the sleeve and the connecting rod.
[0008] When the threaded block moves, it will drive the connecting rod to move. If one end of the locking strip abuts against the wall, it will cause the spring to compress, so that the locking strip will generate a certain pre-tightening force on the wall. At the same time, when the nail body becomes loose, the locking strip can continue to be locked in different positions in the wall under the action of the spring, preventing the nail body from slipping and becoming loose.
[0009] Furthermore, a first hinge joint is fixedly connected to the threaded block, one end of the sleeve is hinged to the threaded block through the first hinge joint, a second hinge joint is fixedly connected to the locking strip, and one end of the connecting rod is hinged to the locking strip through the second hinge joint.
[0010] By using the first and second hinge joints, the locking strip can be deflected when the threaded block moves.
[0011] Furthermore, a guide groove is provided on the inner sidewall, and a guide block that slides within the guide groove is fixedly connected to the threaded block.
[0012] With the guide groove and guide block set up, when the guide block moves to the limit position, it will abut against the side wall of the guide groove. At this time, the locking strip can abut against the wall with the maximum force.
[0013] Furthermore, the plane perpendicular to the nail axis is set as the first plane, and the projection range of the rotating hole on the first plane is smaller than the projection range of the hexagonal hole on the first plane.
[0014] A larger hex wrench can be used to turn the nail head, and after the nail body is screwed into the wall, a smaller hex wrench can be used to turn the screw rod to fix the retaining strip in place and prevent it from loosening.
[0015] Furthermore, a washer is fixedly connected to the nail head, and multiple circumferentially distributed support plates are rotatably connected to the washer. A rotating ring is also rotatably connected to the nail head, and a protrusion is fixedly connected to the support plate. A sliding groove for the protrusion to be inserted is provided on the rotating ring.
[0016] By using the shims and support plates, the position of one end of the support plate can be adjusted by deflecting the support plate, thereby adjusting the support range of the fixing nail on the insulation board.
[0017] Furthermore, the locking strip is provided with a rotating shaft, which rotates and engages with the side wall of the locking groove.
[0018] By deflecting the locking strip around the rotating shaft, one end of the locking strip deflects out of the locking groove, thereby stably locking the nail body.
[0019] Furthermore, a rotating shaft is provided on the support plate, and the rotating shaft is in rotational engagement with the washer.
[0020] By rotating the support plate around the rotating part, the support plate can be adjusted to adjust the range of support for the insulation board.
[0021] The beneficial effects of this application are as follows:
[0022] 1. With the screw and locking strip in place, after the nail body is inserted into the outer wall through the hexagonal hole, the screw is rotated through the rotating hole, which in turn causes the threaded block to move, causing the locking strip to deflect and fix the nail body to prevent it from loosening.
[0023] 2. With the spring in place, when one end of the locking strip abuts against the wall, the spring will be compressed, which will cause the locking strip to exert a certain pre-tightening force on the wall. At the same time, when the nail body becomes loose, the locking strip can continue to be locked in different positions in the wall under the action of the spring, preventing the nail body from slipping and becoming loose.
[0024] 3. By using the shims and support plates, the position of one end of the support plate can be adjusted by deflecting the support plate, thereby adjusting the support range of the fixing nail on the insulation board. Attached Figure Description

[0040] Reference Figure 1-5A special reinforcement nail for preventing loosening of exterior walls includes: a nail head 10, a nail body 11, a hexagonal hole 12, an inner hole 13, a screw 14, a rotating head 15, a rotating hole 16, a locking groove 17, a locking strip 18, a threaded block 19, and a hinged rod. When installing insulation boards, the nail body 11 passes through the insulation board and is screwed into the exterior wall to fix the insulation board. A washer 20 is fixedly connected to the nail head 10, and three circumferentially distributed support plates 21 are rotatably connected to the washer 20. A rotating shaft 22 is provided on the support plates 21, and the rotating shaft 22 rotatably engages with the washer 20. A rotating ring 23 is also rotatably connected to the nail head 10, and a protrusion 24 is fixedly connected to the support plates 21. The rotating ring 23 has a sliding groove 25 for the protrusion 24 to be inserted into. When the rotating ring 23 is rotated, the support plate 21 can be driven to deflect around the rotating shaft 22 under the action of the sliding groove 25 and the protrusion 24. At this time, one end of the support plate 21 gradually moves away from the axis of the reinforcing nail, adjusting the support range of the support plate 21 on the insulation board.
[0041] In one embodiment, the nail head 10 has a hexagonal hole 12, and the nail body 11 has an inner hole 13. A screw 14 is rotatably connected to the inner hole 13, and one end of the screw 14 is fixedly connected to a rotating head 15. The rotating head 15 has a rotating hole 16. One end of the rotating head extends into the hexagonal hole 12. A plane perpendicular to the nail axis is defined as a first plane, and the projection range of the rotating hole 16 on the first plane is smaller than the projection range of the hexagonal hole 12 on the first plane. After the nail body 11 is inserted into the outer wall through the hexagonal hole 12, the screw 14 is rotated through the rotating hole 16. The nail body 11 has circumferentially distributed locking grooves 17, and a locking strip 18 is rotatably connected to the locking groove 17. The locking strip 18 is provided with a rotating shaft portion 26, which rotatably engages with the side wall of the locking groove 17. A threaded block 19 is slidably connected in the inner hole 13. The threaded block 19 is threadedly engaged with the screw 14. A hinged rod is connected to the locking strip 18 bracket of the threaded block 19. One end of the hinged rod is hinged to the threaded block 19, and the other end is hinged to the locking strip 18. Rotating the screw 14 will cause the hinged rod to move, which in turn will cause the locking strip 18 to deflect around the rotating shaft 26, so that the locking strip 18 is locked in the wall, fixing the nail body 11 and preventing it from loosening. A guide groove 27 is provided on the side wall of the inner hole 13, and a guide block 31 is fixedly connected to the threaded block 19 and slides within the guide groove 27.
[0042] In one embodiment, the hinge member includes a sleeve 28 and a connecting rod 29. The sleeve 28 is fitted onto the connecting rod 29 and slides in cooperation with the connecting rod 29, allowing the hinge member to extend and retract as a whole. A spring 30 connects the sleeve 28 and the connecting rod 29. With the spring 30, when one end of the locking strip 18 abuts against the wall, the spring 30 is compressed, causing the locking strip 18 to exert a certain preload on the wall. Simultaneously, when the nail body 11 becomes loose, the locking strip 18 can continue to be locked in different positions within the wall under the action of the spring 30, preventing the nail body 11 from slipping and becoming loose.
[0043] Working process or usage method:
[0044] 1. When installing the insulation board, the nail head 10 is turned by a hex wrench, which causes the nail body 11 to pass through the insulation board and screw into the outer wall. Then, the rotating head 15 is turned by a hex wrench of different models, which drives the screw 14 to rotate, causing the threaded block 19 to move. Then, under the action of the connecting rod 29 and the sleeve 28, the locking strip 18 is deflected and locked in the wall, thus limiting and fixing the nail body 11.
[0045] 2. After the locking strip 18 is secured in the wall, continue to rotate the screw 14 until the guide block 31 abuts against the side wall of the guide groove 27. At this time, the spring 30 is in a compressed state, providing a certain pre-tightening force to the locking strip 18 to prevent loosening. When loosening occurs due to wall damage, the locking strip 18 can always be secured in the wall.
