Description

Technical Field

[0001] This invention belongs to the field of spring clip technology, specifically relating to a spring clip for embedded lighting fixtures and its implementation method. Background Technology

[0002] With the rapid development of building decoration and lighting technology, recessed downlights have become the mainstream lighting choice for modern homes and commercial spaces due to their simple and beautiful appearance and uniform light. Traditional downlight installation mainly relies on spring clips for fixing. The light fixture is secured by manually compressing the spring clips and pushing them into the ceiling opening, using the spring's rebound force.

[0003] However, this installation method has many drawbacks in practical applications, such as:

[0004] 1. Operational safety hazards: During installation, the spring clip needs to be squeezed with your fingers. This is especially dangerous in the narrow space of the ceiling, as it is easy to pinch your fingers. In addition, the spring clip rebounds quickly and can easily lose control and hit the plasterboard, causing damage to the ceiling or light fixtures.

[0005] 2. Low installation efficiency: Since the spring clip needs to be continuously applied to maintain the compressed state, when installing by a single person, one hand is often needed to hold the lamp body and the other hand to compress the spring. The operation is unstable and the installation process is time-consuming and laborious. Summary of the Invention

[0006] The purpose of this invention is to provide a spring clip for recessed lighting fixtures to solve the problems mentioned in the background section. The spring clip provided by this invention eliminates the need for manual spring compression during fixture installation, ensuring both installation safety and improved efficiency.

[0007] Another objective of this invention is to provide a method for implementing a spring clip for embedded lighting fixtures.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a spring clip for recessed lighting fixtures, comprising a mounting block and an unfolding arm, one end of the unfolding arm being rotatably connected to the mounting block, the unfolding arm also being connected to the mounting block via an unfolding arm torsion spring, a rotatable limiting member being rotatably mounted on the mounting block, the limiting member being connected to the mounting block via a reset torsion spring, the limiting member comprising a connecting portion, one end of the connecting portion being connected to an L-shaped trigger portion, a limiting step being provided on the rotating end of the unfolding arm, and a limiting inclined surface corresponding to the limiting step being provided on the inner side of the connecting end of the trigger portion and the connecting portion.

[0009] To ensure stability when the limiting step and the limiting ramp are engaged, the inclination angle of the limiting ramp is further set at 45°.

[0010] To facilitate unlocking, the limiting ramp can be separated from the limiting step. Furthermore, a guide ramp is provided on the upper side of the connection end between the trigger part and the connecting part. The inclination angle of the guide ramp is 30°.

[0011] To achieve a rotatable connection between the deployable arm and the mounting block, the deployable arm and the mounting block are further connected via a deployable arm pivot.

[0012] To enable the trigger to automatically reset, the reset torsion spring is made of stainless steel and has a torque of 0.5 N·m.

[0013] In order to make the trigger part fit with the mounting surface and cause the trigger part to rotate to unlock, the trigger end of the trigger part extends 5-8mm beyond the outer surface of the mounting block.

[0014] Furthermore, in this invention, a plurality of concave grooves are provided on the upper surface of the trigger end of the trigger part.

[0015] To prevent metal fatigue and installation risks caused by the impact when the extendable arm resets after unlocking, and to protect hands and the ceiling surface, a rubber sleeve is further attached to the other end of the extendable arm.

[0016] Furthermore, in this invention, the method for implementing a spring clip for an embedded lamp includes the following steps:

[0017] (i) Secure the mounting block to the housing of the recessed lamp using screws;

[0018] (ii) Rotate the unfolding arm clockwise until the limiting step engages with the limiting inclined surface;

[0019] (III) Insert the recessed lamp into the lamp mounting hole. During the insertion process, the trigger part contacts the mounting surface. Under the obstruction of the mounting surface, the trigger part rotates counterclockwise, causing the limiting inclined surface to separate from the limiting step.

[0020] (iv) The unfolding arm springs back and clamps the back of the mounting surface under the restoring force of the unfolding arm torsion spring, thus fixing the embedded lamp. The trigger part is reset under the restoring force of the reset torsion spring.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. When the unfolding arm is rotated clockwise to a roughly vertical position, the limiting step and the limiting inclined surface cooperate to lock the unfolding arm. Therefore, when installing the recessed lighting fixture, there is no need to manually control the unfolding arm to be in the open state, avoiding the situation of pinching hands during installation, making the installation of the recessed lighting fixture simpler and more convenient.

[0023] 2. The inclination angle of the limiting slope of the present invention is 45° to ensure the stability when the limiting step and the limiting slope are engaged.

[0024] 3. The upper side of the connection end between the trigger part and the connecting part of the present invention is provided with a guide slope. The inclination angle of the guide slope is 30°, so that the limiting slope can be separated from the limiting step when unlocking.

[0025] 4. The other end of the unfolding arm of this invention is connected to a rubber sleeve to avoid metal fatigue and installation risks caused by the impact when the unfolding arm is reset after unlocking, so as to protect the hands and the ceiling surface. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figures 1-6The present invention provides the following technical solution: a spring clip for recessed lighting fixtures, comprising a mounting block 1 and an unfolding arm 6. One end of the unfolding arm 6 is rotatably connected to the mounting block 1 via an unfolding arm pivot 4. An unfolding arm torsion spring 3 is sleeved on the unfolding arm pivot 4. One torsion arm of the unfolding arm torsion spring 3 is limitedly connected to the mounting block 1, and the other torsion arm of the unfolding arm torsion spring 3 is limitedly connected to the unfolding arm 6. The invention also includes a limiting member 5, which includes a connecting part 51. The connecting part 51 has a cylindrical structure and is rotatably connected to the mounting block 1. The connecting part 51 is located below the unfolding arm pivot 4. A reset torsion spring 2 is sleeved on the connecting part 51. 2 is made of stainless steel, and the torque of the reset torsion spring 2 is 0.5 N·m. One torsion arm of the reset torsion spring 2 is limitedly connected to the connecting part 51, and the other torsion arm of the reset torsion spring 2 is limitedly connected to the mounting block 1. One end of the connecting part 51 is integrally formed with an L-shaped trigger part 52. The initial position of the trigger part 52 is horizontal. The rotating end of the unfolding arm 6 is provided with a limiting step 61. The inner side of the connecting end of the trigger part 52 and the connecting part 51 is provided with a limiting inclined surface 54 corresponding to the limiting step 61. When the unfolding arm 6 is rotated clockwise to a roughly vertical state, the limiting step 61 and the limiting inclined surface 54 cooperate to lock the unfolding arm 6.

[0036] By adopting the above technical solution, the present invention provides a limiting member 5, which includes a connecting part 51 and an L-shaped trigger part 52. A limiting step 61 is provided on the rotating end of the unfolding arm 6, and a limiting inclined surface 54 corresponding to the limiting step 61 is provided on the inner side of the connecting end of the trigger part 52 and the connecting part 51. When the unfolding arm 6 is rotated clockwise to a roughly vertical state, the limiting step 61 and the limiting inclined surface 54 cooperate to lock the unfolding arm 6. Thus, when installing the recessed lamp, there is no need to manually control the unfolding arm 6 to be in the open state, avoiding the situation of pinching hands during installation, making the installation of the recessed lamp simpler and more convenient.

[0037] Specifically, the inclination angle of the limiting slope 54 is 45°.

[0038] By adopting the above technical solution, the stability of the limiting step 61 and the limiting inclined surface 54 is guaranteed.

[0039] Specifically, the trigger end of the trigger part 52 extends 5-8mm beyond the outer surface of the mounting block 1. In this embodiment, it is preferably 6mm. The actual design length is determined by the corresponding lamp mounting hole diameter.

[0040] By adopting the above technical solution, the trigger part 52 is made to cooperate with the mounting surface, causing the trigger part 52 to rotate and thus unlocking.

[0041] Example 2

[0042] The difference between this embodiment and embodiment 1 is that, specifically, a guide slope 53 is provided on the upper side of the connection end between the trigger part 52 and the connecting part 51, and the inclination angle of the guide slope 53 is 30°.

[0043] By adopting the above technical solution, it is convenient for the limiting inclined surface 54 to separate from the limiting step 61 when unlocking.

[0044] Example 3

[0045] The difference between this embodiment and embodiment 1 is that, specifically, a rubber sleeve 7 is connected to the other end of the unfolding arm 6.

[0046] By adopting the above technical solution, the impact during the reset of the extended arm 6 after unlocking is avoided, which could lead to metal fatigue and installation risks, thus protecting the hands and ceiling surface.

[0047] Example 4

[0048] The difference between this embodiment and embodiment 1 is that, specifically, the upper surface of the trigger end of the trigger part 52 is provided with several concave grooves 55.

[0049] By adopting the above technical solution, friction is increased, thereby increasing the triggering coefficient and preventing the failure to trigger due to voids.

[0050] Example 5

[0051] Furthermore, the method for implementing a spring clip for an embedded lamp according to the present invention includes the following steps:

[0052] (i) Secure mounting block 1 to the housing of the recessed lamp using screws;

[0053] (ii) Rotate the unfolding arm 6 clockwise until the limiting step 61 engages with the limiting inclined surface 54;

[0054] (III) Insert the recessed lamp into the lamp mounting hole. During the insertion process, the trigger part 52 contacts the mounting surface. Under the obstruction of the mounting surface, the trigger part 52 rotates counterclockwise, causing the limiting inclined surface 54 to separate from the limiting step 61.

[0055] (iv) The unfolding arm 6 springs back and clamps the back of the mounting surface under the restoring force of the unfolding arm torsion spring 3, thus fixing the embedded lamp. The trigger part 52 is reset under the restoring force of the reset torsion spring 2.

[0056] In summary, when the extendable arm 6 is rotated clockwise to a roughly vertical position, the limiting step 61 and the limiting inclined surface 54 engage to lock the extendable arm 6. This eliminates the need for manual control of the extendable arm 6 during installation of the recessed lighting fixture, preventing hand pinching and simplifying installation. The limiting inclined surface 54 has an inclination angle of 45°, ensuring stability when the limiting step 61 engages with it. A guide inclined surface 53 with an inclination angle of 30° is provided on the upper side of the connection between the trigger part 52 and the connecting part 51, facilitating separation of the limiting inclined surface 54 from the limiting step 61 during unlocking. A rubber sleeve 7 is connected to the other end of the extendable arm 6 to prevent metal fatigue and installation risks caused by the impact during the reset of the extendable arm 6 after unlocking, thus protecting hands and the ceiling surface.
