Description

Technical Field

[0001] The utility model belongs to the technical field of LED light strips, in particular to a high-voltage single-panel LED light strip. Background Art

[0002] LED light strips are a type of lamp that assembles LEDs on a strip-shaped FPC flexible circuit board or PCB hard board. Single-panel LED light strips are commonly used as lamps to create atmosphere and decoration in daily life. When using LED light strips, they are usually cut. After cutting, the matching pins are inserted into one end of the light strip to connect with the light strip. When using, the LED light strip is simply fixed and connected to the interface of the power adapter through the pins to power the light strip. However, in daily use, the pins and the ends of the light strip cannot be accurately positioned and plugged when plugging and unplugging. At the same time, it is inconvenient to install and clamp the light strip, which can easily cause the light strip to loosen and reduce the efficiency of use.

[0003] After searching, the existing Chinese patent announcement number is CN213542152U, which discloses an LED light strip, including a circuit board, a plurality of LED lights are connected in parallel on the front of the circuit board, and a plurality of parallel pins are arranged on the back of the circuit board; a transparent member at least covers the back of the circuit board; and a light-transmitting member at least wraps the front of the circuit board. By arranging the transparent member on the back of the circuit board, the light-transmitting member wraps the front of the circuit board. When cutting the LED light strip, the user can observe the parallel pins on the back of the circuit board through the transparent member, and avoid the pin position when cutting, so as to avoid damaging the LED lights.

[0004] The cited patent document also has the same problem. During daily use, the pins and the ends of the light strip cannot be accurately positioned and connected when plugging and unplugging. It is also inconvenient to install and clamp the light strip, which can easily cause the light strip to loosen and reduce its efficiency. Utility Model Content

[0010] Preferably, the interior of the mounting support plate is provided with a stepped circular countersunk hole, and the rotating assembly includes a sealed bearing embedded in the stepped circular countersunk hole and a limiting disc fixed on the circumference of the rotating rod and adapted to the stepped circular countersunk hole.

[0011] Preferably, in this solution, one end of the rotating rod is interference fit with the inner ring of the sealing bearing to allow the H-shaped bracket to rotate and adjust the angle.

[0012] Preferably, in this solution, a first threaded hole is formed on the outer wall of the limiting disc, and a plurality of second threaded holes are formed in a circular array on the stepped platform of the stepped circular countersunk hole.

[0013] Preferably, the limiting disc is adapted to be inserted into the stepped circular countersunk hole, and the limiting disc is connected to the second threaded hole through a locking bolt passing through the first threaded hole to lock the position of the H-shaped bracket.

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0027] This embodiment discloses Figures 1 to 4 A high-voltage single-panel LED light strip is shown, comprising an H-shaped bracket 1, a rotating rod 3 is fixedly installed on the outer wall of one side of the H-shaped bracket 1, and a centripetal clamping assembly for centripetally clamping the light strip body 5 is arranged in the upper and lower concave cavities of the H-shaped bracket 1, each centripetal clamping assembly comprises two symmetrically arranged clamping plates 4 and a plurality of elastic components respectively installed on the back of the clamping plates 4, and the free ends of the two adjacent clamping plates 4 are provided with an extrusion plug-in groove 7 for extruding and inserting the light strip body 5, and the outer walls of the two adjacent clamping plates 4 are provided with a pin installation groove 8 for inserting the pin at the head end of the light strip body 5 that is clamped and fixed after cutting, and the end of the rotating rod 3 facing away from the H-shaped bracket 1 is connected to the mounting support plate 2 through a rotating assembly.

[0028] In this embodiment, the elastic component includes four clamping and extruding spring components 6 symmetrically installed in a rectangular shape on the back side of each clamping plate 4, and a positioning telescopic component installed in the clamping and extruding spring component 6. The positioning telescopic component includes four fixed sleeves 15 symmetrically installed in a rectangular shape on the inner walls of the upper and lower concave cavities of the H-shaped bracket component 1, and a telescopic extension rod 16 symmetrically installed in a rectangular shape on the back side of each clamping plate 4. The telescopic extension rod 16 is adapted to be inserted into the fixed sleeve 15, and the telescopic movement of the fixed sleeve 15 and the telescopic extension rod 16 provides for the telescopic positioning of the telescopic extension rod 16.

[0029] In this embodiment, these clamping and squeezing spring members 6 are pre-set with a certain elastic force, and when the light strip body (5) is inserted, they can automatically tighten to form a stable clamping force. The squeezing and plugging groove (7) is designed to be slightly smaller than the width of the light strip, ensuring that the light strip is neither too tight nor too loose after insertion, which is convenient for insertion and ensures good contact. In addition, a pin installation groove (8) is also provided on the outer wall of one side of each clamping plate (4), which is specially designed for the pin at the head end of the cut light strip, so that the user can directly connect to the power supply after installation.

[0030] In this embodiment, the implementation of the centripetal clamping assembly ensures the fast and accurate installation of the light strip, avoids looseness and poor contact caused by improper installation, and improves the electrical connection stability of the light strip. At the same time, the design of the pin installation groove simplifies the power connection steps, making the entire installation process smoother.

[0031] In this embodiment, the positioning telescopic component is composed of a fixed sleeve (15) and a telescopic extension rod (16), and the two are precisely matched to achieve telescopic adjustment. The telescopic extension rod (16) is inserted into the fixed sleeve (15), and can adapt to light strips of different thicknesses through its own elasticity or manual fine adjustment, ensuring that each clamping can achieve the best fixing state.

[0032] In this embodiment, a stepped circular countersunk hole 10 is opened inside the mounting support plate 2, and the rotating component includes a sealed bearing 11 embedded in the stepped circular countersunk hole 10 and a limiting disc 9 fixed on the circumference of the rotating rod 3 and adapted to the stepped circular countersunk hole 10.

[0033] In this embodiment, one end of the rotating rod 3 is interference-fitted with the inner ring of the sealing bearing 11 to allow the H-shaped bracket member 1 to rotate and adjust the angle.

[0034] In this embodiment, a first threaded hole 12 is formed on the outer wall of the limiting disc 9 , and a plurality of second threaded holes 13 are formed in a circular array on the stepped platform of the stepped circular countersunk hole 10 .

[0035] In this embodiment, the limiting disc 9 is adapted to the stepped circular countersunk hole 10 , and the limiting disc 9 is connected to the second threaded hole 13 through the locking bolt 14 passing through the first threaded hole 12 to lock the position of the H-shaped bracket 1 .

[0036] How it works

[0037] For this high-voltage single-panel LED light strip, the user first rotates the rotating rod 3, and with the help of the cooperation between the sealed bearing 11 of the rotating assembly and the limiting disc 9, the angle of the H-shaped bracket 1 relative to the mounting support disc 2 is adjusted. This process is very smooth and the positioning is accurate, thanks to the low-friction design of the sealed bearing and the precise locking mechanism of the limiting disc through the locking bolt 14. After the rotation is completed, the light strip can be positioned to the most suitable lighting angle. When the LED light strip needs to be installed or replaced, first insert the head end of the cut light strip body 5 into the extrusion and plug-in groove 7 of any clamping plate 4. At this time, the clamping extrusion spring member 6 with pre-set elastic force will automatically apply an appropriate clamping force to ensure that the light strip is firmly squeezed between the two clamping plates. Since the extrusion and plug-in groove matches the size of the light strip, this design not only simplifies the installation steps of the light strip, but also ensures good electrical contact and improves the stability of current transmission;

[0038] In order to adapt to light strips of different thicknesses and ensure uniform clamping, the positioning telescopic component composed of the telescopic extension rod 16 and the fixed sleeve 15 plays a key role. When the light strip body 5 is inserted, the telescopic extension rod 16 can automatically adapt to the thickness of the light strip body 5 under the action of elasticity or slight manual adjustment, and find the best positioning point through telescopic movement, thereby achieving a consistent tightening effect on light strips of different specifications. This adaptive mechanism not only improves the versatility of installation, but also ensures the stable connection of the light strip body 5 during long-term use, avoiding loosening problems caused by vibration and other reasons.
