Description

Technical Field

[0001] The present invention relates to the technical field of lamp installation, and in particular to a lamp hanging device. Background Art

[0002] Plant growth lights simulate sunlight to the greatest extent possible and are widely used in greenhouse crops such as vegetables, fruits, flowers, and fruit trees, as well as lawns, rice seedlings, and tissue culture rooms. They significantly overcome the short daylight hours in winter and spring that can lead to light shortages in greenhouse crops. Insufficient light during the seedling and flowering / fruiting stages can lead to seedling death, low survival rates, developmental abnormalities, and flower and fruit drop, resulting in reduced yields. Using supplemental light sources to illuminate plants can alleviate these issues.

[0003] Existing fixtures typically use a combination of steel clips and screws. The clips are fixed to the fixture, and the screws and wire ropes tighten to achieve installation. This installation method requires tools like screwdrivers and is difficult for one person to perform. It typically requires two people, resulting in cumbersome operation and high labor costs. Screws and screwdrivers can also fall off. Summary of the Invention

[0004] The object of the present invention is to provide a lamp hanging device to improve the convenience and stability of lamp installation.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A lamp hanging device includes a clamping assembly and a cable tie. The clamping assembly includes a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate are hingedly connected. The first clamping plate and the second clamping plate respectively have a first bending portion and a second bending portion. The first bending portion and the second bending portion are respectively used to clamp with the two edges of the lamp housing. The first clamping plate is provided with a first tooth between the first bending portion and the first hinge portion, and the second clamping plate is provided with a second tooth between the second bending portion and the second hinge portion. The first tooth and the second tooth are arranged opposite to each other and are used to clamp the outer periphery of the wire rope; the first clamping plate is provided with a first through hole, and the second clamping plate is provided with a second through hole. The first through hole and the second through hole are for the cable tie to pass through. When in use, the cable tie is also wrapped around the bottom sides of the first bending portion and the second bending portion to clamp the lamp between the first bending portion and the second bending portion.

[0007] Furthermore, the plate body of the first clamping plate on which the first teeth are set is a first flat plate, and the plate body of the second clamping plate on which the second teeth are set is a second flat plate. The upper part of the first flat plate is integrally provided with the first hinge part, the lower part of the first flat plate is integrally provided with the first bending part, and the upper part of the second flat plate is integrally provided with the second hinge part. Note that the first flat plate and the second flat plate are in a left-right relationship, then the front and rear ends of the first flat plate are both provided with first teeth, and the front and rear ends of the second flat plate are both provided with second teeth; the first through hole is provided on the first flat plate, and the second through hole is provided on the second flat plate.

[0008] Furthermore, U-shaped slots are provided on the lower sides of the first bending portion and the second bending portion for the cable tie to be wound around.

[0009] Furthermore, the position where the cable tie passes through the first through hole and the second through hole is lower than the position of the steel wire rope.

[0010] Furthermore, the cable tie is a detachable cable tie.

[0011] Furthermore, the first flat plate and / or the second flat plate is provided with at least one hanging ear for connecting a stabilizing rope or a wire clamp.

[0012] Furthermore, at least one hanging ear is provided on the first plate and the second plate respectively, wherein at least one hanging ear is connected to a stabilizing rope, and the other hanging ear is connected to a wire clamp assembly; the stabilizing rope includes a rope body and locks at both ends, and the locks at both ends of the stabilizing rope are respectively used to connect the lamp hanging devices located on the two steel ropes, and the locks are connected to the hanging ears.

[0013] Furthermore, the wire clamp assembly includes a wire clamp and a wire rope. A lock is provided at one end of the wire rope for connecting to the hanging ear, and the other end is connected to the wire clamp. The wire clamp includes two clips hinged together by a hinge shaft. A torsion spring is provided on the hinge shaft. The two spring arms of the torsion spring respectively press against the inner sides of the two clips. Both clips have an arc-shaped clamping groove, and the two arc-shaped clamping grooves are arranged opposite to each other for clamping the wire rope; the two clips are respectively recorded as the first clip and the second clip, and the axial direction of the hinge shaft is defined as the front-to-back direction. The first support arm is provided at the position of the first clip below the arc-shaped clamping groove, and the second support arm is provided at the position of the second clip below the arc-shaped clamping groove; the first support arm and the second support arm can allow the cable to pass through when the wire clamp is open, and support the cable when the wire clamp is closed.

[0014] Furthermore, the first support arm and the second support arm are spaced apart in the front-to-back direction. When the wire clamp is closed, the first support arm and the second support arm form an annular cavity to support the cable therein.

[0015] Furthermore, the groove wall of the arc-shaped clamping groove is provided with a plurality of pointed portions.

[0016] Beneficial effects of the present invention:

[0017] Two sets of clamping assemblies and cable ties are used to secure the luminaire near its ends. First, secure one end, then the other. To secure one end, the operator first opens the clamping wire rope and luminaire housing, leveraging the rotatable clamping assembly. With their other hand, they manipulate the cable tie, threading it through the two clamping plates of the clamping assembly and then into the tie head. The cable tie tightens as it is pulled, making it easier to secure. Once tightened, the cable tie not only secures the luminaire to the clamping assembly, but also features teeth between the two clamping plates that securely grip the outer circumference of the wire rope, preventing displacement. The combination of the clamping assembly and cable tie allows for single-handed installation of the luminaire without the need for screws or screwdrivers, making it easier to install and preventing the risk of dropped screws or tools. Lifting the other end is also easier because the luminaire is no longer vulnerable to falling.

[0018] Furthermore, by setting up stabilizing ropes, the lamps can be connected in series between the steel ropes to form a grid, which is more stable as a whole and reduces the rotation and shaking of the lamps.

[0019] Furthermore, a cable clamp secures the lamp's cable to the wire rope, effectively organizing and securing the cable. The clamp is specifically designed with an arc-shaped groove that mates with the wire rope, and the two supporting arms of the clamps form a ring cavity for supporting the cable. This clamp is also easy to operate. Furthermore, by securing the cable, it provides an additional layer of security. For example, if the cable tie at one end of the lamp falls off for any reason, the cable still has some support. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] Example:

[0035] like Figures 1-11 As shown, a lighting fixture hanging device includes a clamping assembly and a cable tie 3. The clamping assembly includes a first clamping plate 1 and a second clamping plate 2. The first clamping plate 1 and the second clamping plate 2 are hingedly connected at their upper portions. Each clamping plate has a hinged portion, which is a sleeve structure that allows a hinged rod 4 to pass through. The two clamping plates can rotate relative to each other to open or close. The upper portion of the first clamping plate 1 is designated as the first hinged portion 13, and the upper portion of the second clamping plate 2 is designated as the second hinged portion 23. The axis of the hinged rod 4 is defined as the front-to-back direction.

[0036] The first and second clamping plates 1 and 2 respectively have a first bent portion 11 and a second bent portion 21, which are used to engage with the two edges of the housing of the lamp 6. In this embodiment, the lamp 6 has an aluminum alloy housing and is generally elongated. The first and second bent portions 11 and 21 each have an arc-shaped notch that fits the housing of the lamp 6, and the two bent portions clamp the lamp 6.

[0037] The first clamping plate 1 is provided with a first tooth 14 between the first bending portion 11 and the first hinge portion 13 , and the second clamping plate 2 is provided with a second tooth 24 between the second bending portion 21 and the second hinge portion 23 . The first tooth 14 and the second tooth 24 are arranged opposite to each other and are used to clamp the outer circumference of the wire rope 5 .

[0038] The first plate 12 of the first clamping plate 1 is provided with the first teeth 14, while the second plate 22 of the second clamping plate 2 is provided with the second teeth 24. The upper portion of the first plate 12 is integrally formed with the first hinge portion 13, the lower portion of the first plate 12 is integrally formed with the first bend portion 11, and the upper portion of the second plate 22 is integrally formed with the second hinge portion 23. The first and second plates 12 and 22 are arranged in a left-right relationship. Therefore, the first plate 12 is provided with first teeth 14 at both the front and rear ends, and the second plate 22 is provided with second teeth 24 at both the front and rear ends. In this embodiment, three first teeth 14 and three second teeth 24 are provided on each side, forming a sawtooth pattern.

[0039] The first clamping plate 1 and the second clamping plate 2 can be made of stainless steel plates.

[0040] A first through hole 15 is provided on the first flat plate 12, and a second through hole 26 is provided on the second flat plate 22. The first through hole 15 and the second through hole 26 are for a cable tie to pass through. During use, the cable tie is also wound around the bottom sides of the first and second bent portions 11, 21 to clamp the lamp 6 between the first and second bent portions 11, 21. The through holes are rectangular holes with a diameter slightly larger than the cable tie to facilitate the cable tie's passage, but the through holes should not be too large to prevent the cable tie from being misplaced.

[0041] The bottoms of the first and second through-holes 15, 26 are positioned adjacent to the upper sides of the corresponding bends. This allows the cable tie to rest squarely against the bend after passing through the corresponding through-holes, creating a large contact area between the cable tie and the bend, and ensuring a more secure connection. The first and second through-holes 15, 26 are positioned in a corresponding, bilaterally symmetrical manner, allowing the cable tie to pass through in a straight line. Furthermore, the close proximity of the two through-holes and the inherent rigidity of the nylon cable tie make it relatively easy to pass through during installation.

[0042] The lower sides of the first and second bent portions 11, 21 are each provided with a U-shaped slot 25 for the cable tie to be wound around. That is, the lower portion of the cable tie passes through the U-shaped slot 25. The U-shaped slot 25 ensures that the cable tie is positioned more accurately when in use, serving as a pre-positioning mechanism. Furthermore, the cable tie is confined within the U-shaped slot 25, preventing it from moving forward or backward.

[0043] The position where the cable tie passes through the first through hole 15 and the second through hole 26 is lower than the position of the wire rope 5. The wire rope 5 here refers to the one set in the greenhouse or other occasions for hanging lamps 6. A horizontally set wire rope 5 can be used to install several lamps.

[0044] Figure 3 As shown, the cable tie 3 is a detachable cable tie, which adopts the structure of the prior art; other embodiments may also adopt existing non-detachable cable ties. A brief introduction is as follows: the detachable cable tie includes a strap 31 and a strap head 32. The strap head 32 has a rectangular hole and is also provided with a clip 33. The strap 31 is provided with a row of teeth. When the strap 31 is passed through the rectangular hole during use, the clip 33 and the teeth on the strap 31 form a one-way stop. That is, the strap 31 can be tightened and the strap 31 will not automatically fall out. When the clip 33 is pressed, it contacts the limit of the teeth on the strap 31, and the strap 31 can fall out.

[0045] First, take a lamp 6 to be hoisted on the wire rope 5 as an example to illustrate the hoisting method of the hoisting device of this embodiment. After hoisting, Figure 4 shown.

[0046] The operator holds a clamping assembly in one hand and holds the lamp 6 in the other hand. The lamp 6 is located at the lower side of the wire rope 5, and the clamping assembly is clamped from above the wire rope 5. The two clamping plates of the clamping assembly can be easily opened with a single hand, and the arc-shaped notch of the clamping plate is initially matched with the edge of the lamp 6 shell. At this time, the same hand can hold the clamping assembly and the lamp 6; at this time, the other hand takes out the cable tie, and the cable tie and the clamping assembly can be pre-placed in the tool bag at the same time (carried by the operator or placed somewhere). The hand holding the clamping assembly can simultaneously press one end of the cable tie (one side of the cable tie head 32) or pinch it, and the other hand passes the strap 31 around the lower side of the lamp 6 from the U-shaped slot of the bent part on one side, and comes out from the U-shaped slot on the other side. The strap 31 passes through the through holes on the two clamping plates, and then passes through the cable tie head 32, and is tightened by force to complete the fixation. Under the action of the tie force, the position of the lamp relative to the clamping assembly is relatively fixed, and at the same time the teeth on the two clamping plates bite the wire rope 5, so the clamping assembly will not easily move axially relative to the wire rope 5 or rotate around the wire rope 5.

[0047] Lighting fixtures are typically long and narrow, so it's best to use two clip-on assemblies and cable ties, one for securing the fixture near each end. Once one end is secured, the other end is easier to access because it's no longer vulnerable to falling. Using the same method as above, secure the other end with another clip-on assembly and cable tie. This process, using the clip-on assemblies and cable ties, allows for the fixture to be hoisted without the need for screws, screwdrivers, or other tools. This makes hoisting more convenient and avoids the risk of dropped screws or tools.

[0048] Nylon cable ties themselves have high tensile strength and impact resistance, strong acid and alkali resistance, can withstand certain high and low temperature environments, and have strong adaptability to the environment.

[0049] Furthermore, in order to improve the stability of multiple groups of lamps, at least one hanging ear 27 is provided on the first plate 12 and the second plate 22 for connecting a stabilizing rope, such as Figure 5 shown.

[0050] At least one lug 27 is provided on each of the first and second flat plates 12 and 22, wherein at least one lug 27 is connected to a stabilizing rope. In this embodiment, two lugs 27 are provided. The lug 27 can be a ring, a semicircular ring, a triangle, etc., as long as it can be locked and hung.

[0051] like Figure 6 As shown, the stabilizing rope includes a rope body 73 and lock buckles at both ends, which are recorded as first lock buckles 71. The first lock buckles 71 at both ends of the stabilizing rope are respectively used to connect the lamps and the hoisting devices located on the two steel wire ropes. The first lock buckle 71 is connected to the hanging ear 27. The rope body 73 can be made of steel wire, and the two ends of the rope body 73 are respectively connected to the first lock buckle 71. The steel wire can be passed through and then folded back, and the steel wire can be fixed by flattening the rope loop 72. The first lock buckle 71 has a pressing arm 711, which is hinged on the lock buckle body and can be pressed to open. After closing, the rope body 73 and the first lock buckle 71 will not separate without the action of external human force. The clamping components on the two steel wire ropes are connected through the stabilizing rope to improve the overall stability, such as preventing the lamp from rotating and shaking. If there are three or more steel ropes arranged in parallel, the side walls of the first flat plate 12 and the second flat plate 22 can also be provided with hanging ears 27, that is, the middle clamping component and the clamping components on both sides (on the other steel ropes) are connected by stabilizing ropes.

[0052] Another mounting lug 27 on the tablet connects to a wire clamp assembly, which includes a wire clamp 83 and a cord 82. Cord 82 has a buckle at one end for attaching to mounting lug 27 and a buckle at the other end for attaching to clamp 83. This buckle is referred to as second buckle 81. While its structure is identical to first buckle 71, it is smaller in size.

[0053] The wire clamp 83 comprises two clips hinged together by a hinge 833. A torsion spring 838 is mounted on the hinge 833. The two spring arms of the torsion spring 838 abut the inner sides of the two clips, each of which has a corresponding spring reservoir 8311. The ends of the torsion spring 838 are located within the reservoirs 8311. Both clips have arcuate clamping grooves 835, which are arranged opposite each other to clamp the wire rope 5. The walls of the arcuate clamping grooves 835 are provided with several sharp points 8351 to better engage the wire rope 5.

[0054] The two clips are designated as first clip 831 and second clip 832, respectively. The axis of hinge shaft 833 is defined as the front-to-back direction. A first support arm 836 is provided on first clip 831, located below arcuate slot 835. A second support arm 837 is provided on second clip 832, located below arcuate slot 835. First and second support arms 836, 837 allow cables to pass through when cable clamp 83 is open, and support the cables when clamp 83 is closed. The cables are those attached to lamp 6 and can be power cables or cables combining power supply and control. Cable clamp 83 secures and organizes the cables.

[0055] The first clamping piece 831 and the second clamping piece 832 are both provided with a rope threading hole 834. Generally, one of them is used. Two rope threading holes are designed to be approximately symmetrical. Of course, two rope threading holes may also be used in some occasions.

[0056] The first support arm 836 and the second support arm 837 are spaced apart in the front-to-back direction. When the cable clamp 83 is closed, the first support arm 836 and the second support arm 837 form an annular cavity to support the cable therein. The first support arm 836 and the second support arm 837 are spaced apart in the front-to-back direction. It can be understood that the thickness of each of the first support arm 836 and the second support arm 837 is less than the thickness of the clip in the front-to-back direction. When the first support arm 836 and the second support arm 837 are interlaced (i.e., when the cable clamp is closed), the total thickness is close to the thickness of the clip in the front-to-back direction.

[0057] During use, after the lamp 6 is fixed, the operator pinches the wire clamp 83, opens the wire clamp 83, and uses the arc-shaped clamping groove 835 on the inner side of the clamp to clamp the wire rope 5. During the opening process of the wire clamp 83, the cable on the lamp 6 can be placed on the support arm on one side of the wire clamp 83. After the wire clamp 83 is loosened, the wire clamp 83 automatically closes under the restoring force of the torsion spring 838, and the arc-shaped clamping groove 835 of the two clamps is clamped on the wire rope 5; the first support arm 836 and the second support arm 837 form an annular cavity to support the cable therein.

[0058] The inner diameter of the annular cavity is slightly larger than the outer diameter of the cable, which facilitates the insertion of the cable. In other embodiments, a soft material layer, such as a silicone layer, can be provided on the inner side of the support arm. After the layer is provided, the annular cavities of the two support arms can clamp the outer circumference of the cable after the cable is inserted, making the cable more stable and preventing damage to the cable.

[0059] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
