Description

Technical Field

[0001] This invention relates to the field of fixed installation technology, and more specifically, to quick-installation and disassembly fasteners for fixing electronic products to walls or ceilings. Background Technology

[0002] Installing electronic devices, such as lights, decorative lights, fans, and audio equipment, on the ceiling or walls of a house usually requires tools or structures for fixing and suspending them. Typically, a mounting plate is fixed to the ceiling or wall with screws, and the electronic device is then suspended from the mounting plate. This installation method can easily damage the ceiling or walls and is difficult to remove after installation.

[0003] Currently, some mounting plates have clips on their bottom surface with springs inside. The springs' elasticity pushes the clips to press the mounting plate together, allowing electronic equipment to be installed on ceilings or walls. However, due to the significant weight of the mounting plate and electronic equipment, the springs require high elasticity. Furthermore, after prolonged use, the springs experience elastic fatigue and are prone to rebound, resulting in insecure fixing and easy loosening.

[0004] Therefore, it is necessary to develop new fasteners that allow for quick installation and removal to address the shortcomings of existing technologies. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a fastening fastener for quick installation and disassembly, used to mount electronic devices onto a board. By setting up mounting components and fastener components, the fastener clamps the wall or ceiling between them, making it firmly fixed, not easy to loosen, and easy to install and disassemble, thus solving the shortcomings of the existing technology.

[0006] The technical solution of the present invention is as follows: A fastening fastener for quick installation and removal, used to install electronic devices at mounting holes in a board, comprising a mounting assembly and at least one fastener assembly; the mounting assembly includes a mounting plate, a mating cylinder disposed on the bottom surface of the mounting plate, and at least one guide extending vertically downward from the bottom surface of the mounting plate; the mating cylinder fits against the wall of the mounting hole, and the mounting plate is disposed around the mounting hole on the top surface of the mounting plate; the guide is disposed within the mating cylinder and extends out of the mating cylinder; the fastener assembly is disposed on the guide and abuts against the bottom surface of the board, thereby clamping the board between the mounting plate and the fastener assembly.

[0007] The fastener assembly has a clamping member with an acute angle between the clamping member and the guide member, and it is inclined upward to abut against the bottom surface of the plate.

[0008] The fastener assembly includes a base; the base is mounted on the guide member, and the clamping member is pivotally connected to the base.

[0009] The base has a mounting post on each of its two opposite sides, and the two ends of a torsion spring are respectively wound around the mounting post; the clamping member includes a main board and two side plates on both sides of the main board, and one end of each of the two side plates is provided with a mounting groove; the mounting post is inserted into the mounting groove, thereby pivotally connecting the clamping member to the base; the main board is provided with a blocking part, and a gap is formed between the blocking part and the main board; the middle part of the torsion spring passes through the gap and elastically abuts against the clamping member, so that the other end of the clamping member can be tilted towards the mounting plate, forming an acute angle with the guide member, and abutting against the plate.

[0010] The guide member is cylindrical with a hollow inner cavity and a long groove on its side wall that connects to the inner cavity; a first elastic member is a circular spring built into the inner cavity of the guide member; the base includes a frame and a central post located at the center of the frame, the central post being connected to the frame through a connecting part; the frame is fitted over the guide member; the connecting part is inserted into and passes through the long groove, the central post is placed in the inner cavity of the guide member, and one end of the central post abuts against the first elastic member.

[0011] The mounting plate has a first through hole located directly opposite the central column.

[0012] A blocking member is also provided at the bottom end of the guide member. When the clamping member is pushed along the guide member away from the mounting plate by the base, the clamping member moves with it. When the clamping member contacts the blocking member and is blocked by it, it rotates around the mounting post towards the guide member and is stored under the mounting plate.

[0013] The fastener assembly also includes a locking member located beside the guide member and pivotally connected to the bottom surface of the mounting plate. The locking member can be rotated to abut against the base of the fastener to lock it, or the locking member can be moved to release the base of the fastener.

[0014] The locking member has a second through hole in the middle, and two opposite pairs of holes protrude a locking part and a toggle part towards the base, respectively; the bottom surface of the mounting plate has a mounting post, which passes through the second through hole of the locking member, thereby pivotally connecting the locking member to the mounting post.

[0015] The mounting plate is further provided with a receiving groove between the locking member and the guide member, and a second elastic member is provided in the receiving groove, which elastically abuts against the locking member.

[0016] The beneficial effects of this invention are as follows: The quick-installation and disassembly fastener of this invention only requires pre-drilling mounting holes on the plate. The plate can be clamped by the mounting assembly and the fastener assembly, allowing for quick and easy installation and disassembly without damaging the plate. The fastener assembly has a clamping member that forms an acute angle with the guide member. That is, the clamping member, the guide member, and the plate form a right-angled triangle, resulting in a stable structure that allows the clamping member to firmly support the plate without loosening.

[0026] To make the objectives, technical solutions, and effects of this invention clearer, the invention will be further described below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A quick-installation and detachable fastener 10 is used to mount an electronic device 11 onto a panel 2. The panel 2 can be a ceiling or roof panel. A mounting hole 3 is cut into the panel 2. The quick-installation and detachable fastener 10 is installed at the mounting hole 33 and includes a mounting assembly 100 and at least one fastener assembly 200. The mounting assembly 100 includes a mounting plate 110, a mating sleeve 120 disposed on the bottom surface of the mounting plate 110, and at least one guide member 130 extending vertically downward from the bottom surface of the mounting plate 110. Preferably, four guide members 130 are provided, evenly and symmetrically distributed on the mounting plate 110. The periphery of the mounting plate 110 is disposed around the mounting hole 3 on the top surface of the mounting plate 110, and the mating sleeve 120 fits into the mounting hole 3 on the panel 2. The electronic device 1 is mounted at the center of the mounting plate 110. The electronic device 1 can be a lamp, chandelier, fan, audio equipment, etc. The guide member 130 is disposed inside the mating cylinder 120 and extends out of the guide cylinder 120 to abut against the bottom surface of the plate 2, thereby fixing the plate 2 between the mounting plate 110 and the fastener assembly 200.

[0028] Reference Figure 3 The fastener assembly 200 has a clamping member 230, which forms an acute angle α with the guide member 130, and tilts upward to abut against the bottom surface of the plate 2. That is, the clamping member 230, the guide member 130, and the plate 2 form a right-angled triangle, providing a stable structure that allows the clamping member 230 to firmly support the plate 2 without loosening.

[0029] Reference Figure 3 and Figure 5 The fastener assembly 200 includes a base 210. The base 210 is mounted on the guide member 130, and the clamping member 230 is pivotally connected to the base 210. Specifically, the base 210 has a mounting post 214 on each of its two opposite sides, and the two ends 241 of a torsion spring 240 are respectively wound around the mounting post 214.

[0030] Reference Figure 5The clamping member 230 includes a main board 231 and two side plates 232 disposed on both sides of the main board 231. Each side plate 232 has a mounting groove 233 at one end. Mounting posts 214 are provided on both sides of the frame 211. The mounting posts 214 are inserted into the mounting grooves 233, thereby pivotally connecting the clamping member 230 to the base 210. A blocking portion 234 is provided on the main board 231. A gap 235 is formed between the blocking portion 234 and the main board 231. The middle portion 242 of the torsion spring 241 passes through the gap 235 and elastically abuts against the blocking portion 234, allowing the other end of the clamping member 230 to tilt towards the mounting plate 110, forming an acute angle with the guide member 130 and abutting against the plate 2. The other end of the clamping member 230 is provided with ratchet teeth 235, which can grip the plate 2.

[0031] The fastener assembly 200 further includes a first elastic element 220, which is located below the base 210 and elastically abuts against the base 210. During installation, under the action of external force, the base 210 is pushed to slide along the guide member 130 away from the mounting plate 110, and the first elastic element 220 is compressed, thereby adjusting the distance between the mounting plate 110 and the base 210 to suit plates 2 of different thicknesses. When the plate 2 is placed between the base 210 and the mounting plate 110, the base 210 is released. Under the elastic force of the first elastic element 220, the base 210 slides towards the mounting plate 110 and abuts against the plate 2, thereby clamping the plate 2 between the mounting plate 110 and the base 210. The quick-installation and disassembly fastener 210 can be quickly installed on the plate 2, and is firmly fixed without loosening.

[0032] Reference Figure 3 , Figure 4 and Figure 5 The guide member 130 is cylindrical with a hollow inner cavity 131 and a long groove 132 communicating with the inner cavity on its side wall. The first elastic member 220 is a circular spring built into the inner cavity of the guide member 130. The base 210 includes a frame 211 and a central post 212 located at the center of the frame. The central post 212 is connected to the frame 211 through a connecting part 213. The frame 211 is sleeved on the guide member 130; the connecting part 213 is inserted into and passes through the long groove 132; the central post 212 is placed in the inner cavity of the guide member 130, with one end abutting against the first elastic member 220; the other end abuts against the mounting plate 110 when not in use and against the plate 1 when in use.

[0033] Reference Figure 3The mounting plate 110 has a first through hole 111 located opposite the central post 212. During installation, the user can insert an installation tool, such as a push rod, into the first through hole 111 to push the base 210 and compress the first elastic member 220, thereby pushing the base 210 to move away from the mounting plate 110 along the guide member 130.

[0034] Since the clamping member 230 is located on one side of the base 210 and clamps the plate 2 together with the mounting plate 110, its orthogonal projection on the mounting plate 110 may be outside the mounting plate 110, or in other words, the clamping member 230 may extend beyond the periphery of the mounting plate 110. Therefore, during installation, the clamping member 230 may be too large to pass through the mounting hole 3 on the plate 1. For this reason, a blocking member 140 is also provided at the bottom end of the guide member 130. Figure 6 As shown, when the clamping member 230 is pushed along the guide member 130 away from the mounting plate 110 by the base 210, the clamping member 230 moves with it. When the clamping member 230 contacts the blocking member 140 and is blocked by it, it rotates around the mounting post 214 towards the guide member 130 and is stored under the mounting plate 110, thereby facilitating the quick-installation and disassembly fixing fastener 10 to pass through the mounting hole 3, placing the mounting plate 110 on the plate 2, and placing the fastener assembly 200 under the plate.

[0035] like Figure 7 As shown, the blocking member 140 is disposed at the bottom end of the guide member 130 and is also used to abut against the first elastic member 220.

[0036] Reference Figure 3 , Figure 4 and Figure 6 The fastener assembly 200 further includes a locking member 240, which is located beside the guide member 130 and pivotally connected to the bottom surface of the mounting plate 110, for locking or releasing the base 210.

[0037] Specifically, such as Figure 6 As shown, when the base 210 moves to the appropriate position along the guide member 130, the locking member 240 locks the base 210, preventing it from moving under the elastic force of the first elastic member 220. After the plate 2 is placed between the mounting plate 110 and the base 210, the locking member 240 releases the base 210, and the first elastic member 220 pushes the base 210 toward the plate 2, thereby causing the base 210 to clamp the plate 2 between the mounting plate 110 and the plate 2.

[0038] Preferably, refer to Figure 8 and Figure 9 The locking member 240 has a second through hole (not shown) in the middle, with two opposite pairs of holes protruding towards the base 210, one a locking part 242 and the other a toggle part 243. The bottom surface of the mounting plate 110 has a rotating post 112 that passes through the second through hole (not shown) of the locking member 240, thereby pivotally connecting the locking member 240 to the rotating post 112. The mounting plate 110 has a third through hole 113 at a position corresponding to the locking member 240. The toggle part 243 extends into the third through hole 113, allowing the user to rotate the locking member 240 at the third through hole 113, causing the locking part 242 to press against the base 210 to lock it, or to release the base 210. The mounting plate 110 also has a receiving groove 114 between the locking member 240 and the guide member 130. The locking member 240 has a protrusion 244 below the actuating part 243, the protrusion 244 facing the receiving groove 114, and a second elastic member 115 is provided in the receiving groove 114. The second elastic member 115 is sleeved on the protrusion 244 and elastically abuts against the actuating part 243. When the locking part 242 abuts against the base 210, the second elastic member 115 elastically abuts against the actuating part 243 in the opposite direction, so that the locking part 242 can continuously abut against the base 210, thereby locking it. Alternatively, by actuating the actuating part 243, the locking part 242 is disengaged from the base 210, and the base 210 slides along the guide member 130 towards the mounting plate 110 under the elastic force of the first elastic member 220, thereby clamping the plate 2.

[0039] When the quick-installation and disassembly fastener 10 is used, a push rod first pushes the base 210 to overcome the elastic force of the first elastic member 220 and move it away from the mounting plate 110 along the guide member 130. The clamping member 230 moves with the base 210. When the blocking member 140 contacts and blocks the clamping member 230, it overcomes the elastic force of the torsion spring 240, causing the clamping member 230 to move around the mounting post 214 toward the guide member 130 and be stored under the mounting plate 110. Moving the locking member 240 causes the locking part 242 to abut against the base 210 and lock it, thus preventing the base 210 from moving toward the mounting plate 110 under the elastic force of the elastic member. The quick-install and removable fastener 10 is placed at the mounting hole 3 of the plate 2, so that the mounting plate 110 is placed on the plate 2 at the opening of the mounting hole 3, the mating sleeve 120 fits against the mounting hole 3, and the guide member 130 is located below the mounting hole 3. The locking member 240 is moved to release the base 210. Under the action of the first elastic member 220, the base 210 moves towards the mounting plate 110, causing the clamping member 230 to disengage from the blocking member 140. Under the action of the torsion spring 240, its other end rotates away from the guide member 130, and the ratchet abuts against the plate 2, thereby fixing the quick-install and removable fastener 10 onto the plate 2, that is, installing the electronic device mounted on the quick-install and removable fastener 10 onto the plate 2. This installation method is simple and secure.

[0040] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention and should not be construed as limiting the specific implementation of the invention to these descriptions. For those skilled in the art, the architectural form of this invention can be flexibly varied without departing from its conceptual framework, leading to the derivation of a series of products. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
