Description

Technical Field

[0001] This utility model relates to the technical field of lamp connectors, specifically a lamp rotating connector with an adjustable swing angle. Background Technology

[0002] In the field of lighting installation and use, rotating connectors are the core components for adjusting the angle of lighting fixtures. They are widely used in scenarios such as track lights, spotlights, and grid lights where the direction of lighting needs to be flexibly adjusted.

[0003] Existing connectors mostly use simple shaft-hole mating structures (such as metal pins directly inserted into the fixing seat), which lack precise control over the rotation trajectory. When adjusting the lamp angle, the pin is prone to radial displacement within the fixing seat hole, causing the lamp to jam or deviate when swinging, making it impossible to adjust smoothly along the preset arc trajectory. This deviation is more pronounced when the adjustment range is large, affecting the precise control of the lighting angle. Therefore, a lamp rotating connector with an adjustable swing angle is proposed. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a lamp rotating connector with an adjustable swing angle, thus solving the problem of limited swing angle in lamp rotating connectors.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a lamp rotating connector with an adjustable swing angle, comprising a first connecting profile, wherein a rotating shaft seat is fixedly installed on the upper surface of the first connecting profile; The first connecting profile is provided with a rotating mechanism, which includes a second connecting profile and a fixing pin; The second connecting profile is disposed on the upper surface of the first connecting profile, and two fixing pins are fixedly installed on both sides of the second connecting profile. Both fixing pins are rotated on the inner surface of the pivot seat.

[0006] Preferably, the rotating mechanism further includes PC film, with two PC films respectively fixedly sleeved on the outer surfaces of the two fixing pins.

[0007] Preferably, the rotating mechanism further includes springs, with two springs respectively fixedly installed in the inner walls of two fixing pins.

[0008] Preferably, the rotating mechanism further includes sealing heads, with four sealing heads respectively fixedly installed on both sides of the first connecting profile and the second connecting profile.

[0009] (III) Beneficial Effects Compared with the prior art, this utility model provides a lamp rotating connector with an adjustable swing angle, which has the following advantages: 1. This adjustable luminaire rotating connector uses a fixed pin as a rotating shaft that engages with the shaft seat to ensure a stable swing trajectory. A PC film is fitted over the fixed pin to reduce direct metal-to-metal friction, thereby reducing swing resistance and noise. A spring is installed on the inner wall of the fixed pin to provide elastic preload. The combination of these three elements makes the adjustment process smooth and controllable. After the external force is removed, the inertia can be quickly offset, allowing the second connecting profile to drive the luminaire to accurately maintain the target angle and prevent loosening or shaking.

[0010] 2. The swivel-angle rotating connector for lamps uses the first connecting profile as the core carrier, integrating components such as the pivot seat, and connecting the fixed end of the lamp to ensure the overall structural strength and stability. Four sealing heads are installed on both sides of the first and second connecting profiles respectively, which not only seal the port to prevent internal components from falling off, but also cover the end structure of the profile, improving the assembly integrity while optimizing the overall aesthetics of the connector.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a new technical solution: a lamp rotating connector with an adjustable angle, including a first connecting profile 1, and a rotating shaft seat 3 is fixedly installed on the upper surface of the first connecting profile 1; The first connecting profile 1 is provided with a rotating mechanism, which includes a second connecting profile 4 and a fixing pin 5. The second connecting profile 4 is disposed on the upper surface of the first connecting profile 1, and two fixing pins 5 are fixedly installed on both sides of the second connecting profile 4. Both fixing pins 5 are rotated on the inner surface of the pivot seat 3.

[0015] Furthermore, the rotating mechanism also includes PC film 6, with two PC film 6 respectively fixedly sleeved on the outer surface of two fixing pins 5.

[0016] Furthermore, the rotating mechanism also includes springs 7, with two springs 7 respectively fixedly installed in the inner walls of two fixing pins 5.

[0017] Furthermore, the rotating mechanism also includes sealing heads 2, with four sealing heads 2 respectively fixedly installed on both sides of the first connecting profile 1 and the second connecting profile 4; Structural Explanation: First connecting profile 1: It is the basic load-bearing component of the entire connector. The upper surface is fixedly mounted with the pivot seat 3, which provides the installation benchmark and support for other components. As the fixed end, it connects the fixed part of the lamp and integrates the components together through its own structure to ensure the stability of the overall structure. It is the basic carrier for realizing the swing function of the lamp.

[0018] Sealing head 2: There are four in total, which are installed on both sides of the first connecting profile 1 and the second connecting profile 4 respectively. Their main function is to seal the profile port to prevent the internal components of the profile from falling off during use. At the same time, they cover the structure at the end of the profile, improve the overall aesthetics of the connector, and enhance the structural integrity.

[0019] Rotary shaft seat 3: Fixed to the upper surface of the first connecting profile 1, it is a key mating component of the rotating mechanism. Its inner surface forms a rotating connection with the two fixed pins 5, providing a rotation fulcrum and trajectory restriction for the fixed pins 5, ensuring that the second connecting profile 4 can swing stably around it, and is an important support structure for realizing angle adjustment.

[0020] The second connecting profile 4 is set on the upper surface of the first connecting profile 1 and serves as the connecting carrier for the movable end of the lamp. Fixing pins 5 are installed on both sides of it. The swing is achieved through the cooperation of the fixing pins 5 and the rotating shaft seat 3, thereby driving the movable end of the lamp to adjust the angle. It is the core component for transmitting the swing action.

[0021] Fixed pins 5: There are two of them, which are fixed on both sides of the second connecting profile 4 and both form a rotational fit with the inner surface of the rotating shaft seat 3. They serve as rotating shafts to connect the second connecting profile 4 and the rotating shaft seat 3. They are the key rotating components for realizing the swing function and directly transmit the swing action.

[0022] PC film 6: There are two of them, which are fixedly sleeved on the outer surface of the two fixing pins 5 respectively. Their function is to reduce the direct friction between the fixing pins 5 and the rotating shaft seat 3, reduce the resistance and wear during rotation, make the swing smoother, reduce noise, and extend the service life of the parts.

[0023] Spring 7: There are two springs, which are installed in the inner walls of the two fixing pins 5 respectively. They can provide elastic preload to make the fixing pins 5 and the rotating shaft seat 3 fit more tightly, avoid loosening or shaking during swinging, and help the lamp maintain stable positioning after the angle is adjusted. When no external force is applied, the swivel-angle rotating connector for the lamp maintains a preset initial relative angle between the second connecting profile 4 and the first connecting profile 1. At this time, the fixing pin 5 is stationary in the support hole of the rotating shaft seat 3, the PC film 6 is in a natural fit, the spring 7 has no obvious deformation and only maintains a small preload, and the four sealing heads 2 seal the ends of each profile. The entire device is in a stable stationary state. When the user needs to adjust the lamp angle, an external force is applied to the lamp connected to the second connecting profile 4. The external force is transmitted to the second connecting profile 4 through the lamp, causing the second connecting profile 4 to start rotating around the axis of the fixing pin 5. At this time, the fixing pin 5 rotates synchronously in the support hole of the rotating shaft seat 3, and the PC film 6 sleeved on the fixing pin 5 rotates along with it, reducing... The lack of direct friction between metal parts avoids producing harsh noises. At the same time, the spring 7 on the inner wall of the fixing pin 5 is slightly compressed due to the relative movement with the rotating shaft seat 3, generating elastic damping force, making the rotation process smooth and controllable, and preventing rapid rotation due to excessive external force. When the lamp is adjusted to the target angle, the user removes the applied external force. At this time, the elastic damping force of the spring 7 and the friction force of the PC film 6 work together to quickly counteract the inertial rotation tendency of the fixing pin 5, causing the fixing pin 5 to stop rotating. The second connecting profile 4 also stops with the fixing pin 5, and is stably maintained at the adjusted angle position. The lamp is also fixed at the target angle, completing a complete swing angle adjustment process. If further adjustment is needed, the above steps of external force driving and undoing positioning can be repeated.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
