Description

Technical Field

[0001] This utility model relates to the technical field of lighting equipment installation accessories, and in particular to a T-shaped cross-shaped wire threading structure. Background Technology

[0002] In existing lighting equipment installation technology, the T-type connector is a key component for connecting the lamp to the mounting carrier (such as wall, ceiling, bracket, etc.), and the design of its wire hole directly affects the installation efficiency and stability.

[0003] Currently, most T-shaped wire holes on the market have a one-way through structure, which can lead to problems such as limited wire threading angle, insufficient fixing stability and poor compatibility. This results in time-consuming and labor-intensive installation, and the wires are prone to loosening or shifting due to uneven force, resulting in poor installation effect. Therefore, we propose a T-shaped cross wire threading structure. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a T-shaped cross-shaped threading structure, which allows fasteners (such as wires and screws) to be inserted from eight directions, including horizontal and vertical directions. This solves the alignment problem of traditional one-way holes when installing in narrow spaces or at special angles, and improves installation efficiency by more than 40%.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a T-shaped cross-threading structure, including a T-shaped connecting lamp holder, a detachable light guide column and a bulb. The T-shaped connecting lamp holder includes a connecting seat, which is provided with a first vertical connecting hole, a first horizontal connecting hole, a second vertical connecting hole and a second horizontal connecting hole. The first vertical connecting hole and the first horizontal connecting hole, and the second vertical connecting hole and the second horizontal connecting hole are respectively cross-connected.

[0006] As a preferred embodiment of this utility model, the inner walls of the first vertical connecting hole, the first horizontal connecting hole, the second vertical connecting hole, and the second horizontal connecting hole are all provided with rounded corner transition structures, and the radius of the rounded corner transition structures is 0.5 to 1 mm.

[0007] As a preferred technical solution of this utility model, the connection part between the detachable light guide column and the T-shaped connecting lamp holder is provided with a matching structure of annular protrusion and annular groove.

[0008] As a preferred embodiment of this utility model, the detachable light guide column includes an outer protective ring, a first magnetic component, and a positioning pin. The bulb includes a second magnetic component, a positioning groove, and a rubber ring. The detachable light guide column is magnetically attracted to the second magnetic component on the bulb via the first magnetic component. The positioning pin is inserted into the positioning groove. The rubber ring is used to seal the connection between the detachable light guide column and the bulb.

[0009] In a preferred embodiment of this invention, the first magnetic component is a permanent magnet, the second magnetic component is a magnetic ring, and the attraction force between the permanent magnet and the magnetic ring is ≥30N.

[0010] As a preferred technical solution of this utility model, the number of positioning pins is four and they are evenly distributed at the bottom of the detachable light guide column, and the positioning grooves are set one-to-one with the positioning pins.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By setting the first vertical connecting hole and the first horizontal connecting hole, and the second vertical connecting hole and the second horizontal connecting hole, a double set of cross-shaped wire-passing channels are formed, allowing fasteners (such as wires and screws) to pass through from eight directions in total, both horizontal and vertical. This solves the alignment problem of traditional one-way holes when installing in narrow spaces or at special angles, and improves installation efficiency by more than 40%.

[0013] 2. Through the dual connection of magnetic attraction and positioning, the magnetic attraction between the first and second magnetic components enables the light guide column and the bulb to be quickly connected. With the precise insertion of four evenly distributed positioning pins and positioning slots, assembly can be completed without tools. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example 1:

[0022] like Figures 1-3 As shown, a T-shaped cross-shaped threading structure includes a T-shaped connecting lamp holder 1, a detachable light guide post 2, and a bulb 3. The T-shaped connecting lamp holder 1 includes a connecting base 11, which has a first vertical connecting hole 12, a first horizontal connecting hole 13, a second vertical connecting hole 14, and a second horizontal connecting hole 15. The first vertical connecting hole 12 and the first horizontal connecting hole 13, and the second vertical connecting hole 14 and the second horizontal connecting hole 15 are respectively cross-connected. The inner walls of the first vertical connecting hole 12, the first horizontal connecting hole 13, the second vertical connecting hole 14, and the second horizontal connecting hole 15 are all provided with rounded corner transition structures, and the radius of the rounded corner transition structures is 0.5 to 1 mm. The connection part between the detachable light guide post 2 and the T-shaped connecting lamp holder 1 is provided with a matching structure of annular protrusion and annular groove.

[0023] This embodiment applies to the installation of household ceiling lights:

[0024] T-shaped connecting lamp holder 1: Made of ABS engineering plastic through one-piece injection molding. The horizontal length of the connecting seat 11 is 80mm and the vertical height is 60mm. The diameter of the first vertical connecting hole 12 and the second vertical connecting hole 14 is 5mm, and the axial spacing is 30mm. The diameter of the first horizontal connecting hole 13 and the second horizontal connecting hole 15 is 6mm. The distance between the intersection points of the axis and the vertical hole axis is 20mm. The radius of the inner corner of all holes is 0.8mm.

[0025] Detachable light guide column 2: The bottom outer circumference is provided with an annular protrusion with a width of 3mm and a height of 2mm, which is fitted with the annular groove at the top of the T-shaped connecting lamp holder 1 with a width of 3.1mm and a depth of 2.1mm. After assembly, it can withstand ±5° of angle micro-adjustment without loosening or abnormal noise.

[0026] Installation process: M5 expansion screws are inserted through the first horizontal connecting hole 13 to fix the light fixture to the ceiling keel. Iron wire is inserted through the second vertical connecting hole 14 to assist in the hoisting. The double cross holes allow the light fixture to be adjusted in both horizontal and vertical directions during installation. The final fixing deviation is ≤2mm, which reduces more than 3 adjustment steps compared to the traditional structure.

[0027] The cross-shaped wire-passing hole optimizes installation flexibility: Through the cross-connection design of the first vertical connection hole and the first horizontal connection hole, and the second vertical connection hole and the second horizontal connection hole, a double set of cross-shaped wire-passing channels are formed, allowing fasteners such as wires and screws to be passed in from eight directions, both horizontal and vertical. This solves the alignment problem of traditional unidirectional holes when installing in narrow spaces or at special angles, and improves installation efficiency by more than 40%.

[0028] Rounded corners protect wires and ensure operational safety: The 0.5-1mm rounded corner structure on the inner wall of the hole avoids sharp edges from causing abrasion to wires such as iron wires and electrical wires during the threading process, while reducing the risk of scratches to operators and extending the service life of the wires to 1.5 times that of traditional structures.

[0029] The ring-shaped fit enhances structural stability: The detachable light guide column and the T-shaped connecting lamp holder are fitted together by the nesting of the ring protrusion and the ring groove. This allows for 360° rotation and fine adjustment of the light guide column to facilitate light angle calibration, while also limiting axial wobbling. The concentricity deviation of the connection part is ≤0.1mm, ensuring stable light transmission.

[0030] Example 2:

[0031] In other embodiments, this embodiment discloses, please refer to Figure 4 , Figure 5 As shown, the detachable light guide 2 includes an outer protective ring 21, a first magnetic component 22, and a positioning pin 23. The bulb 3 includes a second magnetic component 31, a positioning groove 32, and a rubber ring 33. The detachable light guide 2 is magnetically attracted to the second magnetic component 31 on the bulb 3 via the first magnetic component 22. The positioning pin 23 is inserted into the positioning groove 32. The rubber ring 33 is used to seal the connection between the detachable light guide 2 and the bulb 3. The first magnetic component 22 is a permanent magnet, and the second magnetic component 31 is a magnetic ring. The attraction force between the permanent magnet and the magnetic ring is ≥30N. There are four positioning pins 23, which are evenly distributed at the bottom of the detachable light guide 2. The positioning groove 32 and the positioning pin 23 are set one-to-one.

[0032] This embodiment is applied to spotlights in shopping mall windows where bulbs need to be frequently replaced to adjust the lighting effect.

[0033] Detachable light guide post 2: The outer protective ring 21 is made of transparent PC material, and the bottom is embedded with a ring-shaped N35 neodymium iron boron permanent magnet first magnetic component 22, which is 2mm thick and 30mm in diameter; the four positioning pins 23 are cylindrical with a diameter of 2mm and a height of 1.5mm, and are evenly distributed along the circumference of the permanent magnet with an adjacent spacing of 90°.

[0034] Bulb 3: The top of the bulb holder is equipped with a low-carbon steel magnetic ring second magnetic component 31, which is 1.5mm thick and 30mm in diameter. The actual measured attraction force with the permanent magnet is 35N. There are four positioning grooves 32 corresponding to the positioning pin position, which are 2.1mm in diameter and 1.6mm deep. The inner wall of the groove is embedded with a 0.3mm thick silicone rubber ring 33.

[0035] Usage effect: When replacing the bulb, a 40N axial pulling force can separate the light guide column from the bulb. The new bulb can be aligned with the positioning groove and gently pushed to be fixed by magnetic attraction. The whole process does not require tools and can be completed by one person in 10 seconds. The rubber ring ensures that there are no water ingress marks at the connection part after 30 minutes of simulated spray test, and the light transmittance of the light guide column remains above 95%.

[0036] Magnetic attraction and positioning dual connection improve assembly efficiency: The magnetic attraction force of the first magnetic component and the second magnetic component is ≥30N, which enables the light guide column and the bulb to be quickly connected. With the precise insertion of four evenly distributed positioning pins and positioning slots, assembly can be completed without tools, taking ≤3 seconds. Traditional threaded connections take 10-15 seconds, and the circumferential positioning deviation is ≤0.5°, ensuring that the light emission direction is consistent.

[0037] Enhanced environmental adaptability through sealing structure: The rubber ring forms a ring seal at the connection point, achieving an IP54 dustproof and waterproof rating. This solves the problem of dust and moisture easily entering through gaps in traditional threaded connections, making it especially suitable for humid environments such as kitchens and bathrooms.

[0038] Modular design facilitates maintenance and replacement: The detachable feature of the magnetic connection allows bulb replacement without rotation. It can be completed simply by axial insertion and removal in a confined space, improving maintenance efficiency by 60%. Furthermore, the guiding effect of the positioning pin and positioning groove prevents structural damage during blind installation.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
