Description

Technical Field

[0001] The invention relates to the technical field of lamp hanging components, and in particular to a tongue-type punch-free installation hanging plate and a height-adjustable chandelier. Background Art

[0002] There are many types of ceiling-mounted lamps in different sizes. When installing, they need to be fixed on the ceiling with expansion screws, and drilling tools are needed to work at height, which not only destroys the beauty of the ceiling, but also causes noise and dust problems. In addition, when replacing lamps, it is difficult to ensure that the position of the fixing holes of the new ceiling lamp is consistent with the original ceiling lamp, and in most cases, new holes have to be drilled.

[0003] The Chinese patent application number CN201410835316.2 discloses a household ceiling lamp punch-free mounting bracket, including a base, a main body bracket, a telescopic bracket and a junction box, wherein the junction box is connected to the upper end of the base, the lower end of the base is connected to the upper end of the main body bracket, the lower end or the upper end of the main body bracket is connected to the telescopic bracket, and the outer end of the telescopic bracket is provided with a ceiling lamp fixing hole; the base is provided with a main body bracket connecting hole, the main body bracket is provided with a base connecting hole, the main body bracket connecting hole and the base connecting hole are placed correspondingly to connect the main body bracket to the base, and the main body bracket can rotate around the main body bracket connecting hole. The screw holes of the base of the invention match the screw holes of the 86-type power supply dark box reserved in the ceiling, and the mounting bracket can be fixed to the ceiling without punching holes, which ensures the integrity and beauty of the ceiling while achieving simple and safe connection of the power cord.

[0004] However, this technology requires connecting the screw holes on the power dark box. However, the screw holes on the power dark box are often damaged after installation and during use, which is why many businesses currently offer power dark box repairers. Obviously, using the existing screw holes on the power dark box as a lighting fixture hanging solution has uncertainties in terms of successful installation and a high risk of falling safety.

[0005] The Chinese patent application number CN202321278059.8 discloses a punch-free lamp mounting bracket, including a long strip-shaped mounting strip, each end of which is provided with a mounting hole, and the mounting strip is detachably connected to the emergency lighting lamp through the mounting holes; two long strip-shaped slots are provided in the middle of the mounting strip, and the slots are stepped, with the larger side of the slots facing the emergency lighting lamp, and a mounting screw is movably arranged in each of the slots, and an adapter is arranged on each of the mounting screws, and the adapter is located in the wire box.

[0006] Although this patented technology eliminates the need for drilling holes in the wall (ceiling panel) when installing traditional lamps, as well as the need to connect to the screw holes on the power supply box, it has problems such as complex structure, high cost, and excessive space occupied by the power supply box, making it difficult to store the lamp hanging wires in the power supply box, and is particularly difficult to adapt to the installation of height-adjustable chandeliers. Summary of the invention

[0007] The purpose of the present invention includes providing a tongue-type punch-free installation hanging plate which can be injection molded in one step, has high production efficiency, low cost, occupies less internal space of a power supply dark box, and is more convenient to install.

[0008] The purpose of the present invention also includes providing a height-adjustable chandelier that can be hoisted and stored with lamp hanging wires through a power supply dark box.

[0009] In order to achieve the above object, the present invention has the following technical solutions:

[0010] The tongue-type punch-free installation hanging plate provided by the present invention comprises a hanging plate body, a threading hole is provided in the middle of the hanging plate body, a snap-on tongue and a screw wedging column are provided on the hanging plate body, one end of the snap-on tongue is close to or adjacent to one side of the hanging plate body, and the other end extends out of the hanging plate body; the screw wedging column is vertically connected to the side of the hanging plate body away from the snap-on tongue.

[0011] Preferably, the snap-fitting tongue is an L-shaped plate, one end of which is connected to the hanging plate body and is close to or adjacent to one side of the hanging plate body, and the other end of which extends out of the hanging plate body.

[0012] Preferably, the cross section of the portion of the L-shaped plate extending out of the hanging plate body is arc-shaped.

[0013] Preferably, the cross-section of the portion of the L-shaped plate extending out of the hanging plate body gradually decreases as it approaches the distal end.

[0014] Preferably, the width of the cross section is equal to the inner diameter of the threading tube.

[0015] Preferably, the screw wedging column includes two quarter-circular tubes, one end of the quarter-circular tube is provided with a semicircular notch, and the other end is provided with a closed inclined surface, and the two quarter-circular tubes are vertically connected to the two ends of the edge of the hanging plate body away from the clamping tongue through the arc surface at the end of the semicircular notch.

[0016] Preferably, a thread for threading a locking wire buckle is provided in the threading hole.

[0017] Preferably, the hanging plate body is a square or circular flat plate.

[0018] Preferably, reinforcing ribs are provided on the upper surface of the flat plate.

[0020] Preferably, the hanging plate body is provided with a strong magnet for connecting to the chassis of the lamp, and / or a preset screw hole, for convenient hanging of more types of lamps.

[0021] Preferably, the hanging plate body is made of ABS plastic.

[0022] A height-adjustable chandelier comprises a lamp holder connected with at least a light bulb, a lamp hanging wire, a locking wire buckle connected to the lamp hanging wire, and the above-mentioned tongue-type punch-free installation hanging plate, wherein:

[0023] The protruding tongue-type punch-free installation hanging plate is plugged into the mouth of the threading tube inserted into the power dark box through the clamping protruding tongue, and is connected to the inner wall of the power dark box by screws through the screw wedge column;

[0024] The upper end of the locking wire buckle is connected to the threading hole on the tongue-type punch-free installation hanging plate by thread connection or clamping;

[0025] The lower end of the lamp hanging wire is connected to the chandelier, and the upper end is electrically connected to the power line after being inserted into a power dark box.

[0026] Preferably, the power supply dark box is made of plastic.

In addition, the two quarter-circular tubes connected to the edge of the hanging plate body are not only several times smaller in volume than the prior art, but also are each located in a corner of the power supply box after connection. Therefore, the present invention hardly occupies the internal space of the power supply box, so that more lamp hanging wires can be easily stored in the power supply box, which can adapt to the hoisting and height adjustment of height-adjustable chandeliers.

[0032] 2. The tongue-type punch-free installation hanging plate provided by the present invention has a simple structure, is easy to be made by integral injection molding, has high production efficiency and low cost.

[0033] 3. When installing the tongue-type punch-free installation hanging plate provided by the present invention, there is no need for a punching process or a screw hole for connecting to the power dark box. Moreover, since it hardly occupies the internal space of the power dark box, it is not easily disturbed by the power line inside the power dark box during installation, and the installation is more convenient.

[0034] 4. The tongue-type punch-free installation hanging plate provided by the present invention is more firmly and reliably connected through the hanging of the clamping tongue and the wedging of two screws and the threaded connection to the power supply dark box. The connection method is adapted to the structural characteristics of the existing power supply dark box and has good applicability. BRIEF DESCRIPTION OF THE DRAWINGS
