Description

Technical Field

[0001] The present invention relates to the field of lighting fixture technology, and particularly to the structure of a hanging ceiling.

Background Art

[0002] As an indispensable infrastructure in modern buildings and home environments, the ease of installation of lighting fixtures and the reliability of electrical connections have always been important issues in the industry. Hanging ceilings are widely used in the lighting fixture field to achieve quick connection and electrical conduction between lighting fixtures and mounting bases (for example, refer to Patent Document 1). In commercial and residential lighting systems, quick connection and electrical conduction technologies between lighting fixtures and mounting bases are widely used. The hanging ceiling, which is an important connection device, enables quick installation and removal of lighting fixtures while ensuring the stability and safety of electrical connections. In the prior art, a hanging ceiling typically includes a mounting housing, a conductive component, and a contact ring. An electrical path is realized by the cooperation of the conductive component and the contact ring, and the lighting fixture is fixed to the mounting base by a mechanical structure. This structure has formed a relatively mature technical system in practical applications.

[0003] However, in the prior art, the installation process of the hanging ceiling for installing lighting fixtures is relatively complicated, and the fitting accuracy between components is required, resulting in a decrease in production efficiency. Furthermore, electrical contact failures are likely to occur due to long-term use, which may affect the normal operation of the lighting fixtures.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In light of the above circumstances, the present invention aims to provide a ceiling hook with improved installation efficiency. [Means for solving the problem]

[0006] To achieve the above objective, the hook ceiling mount of this invention comprises a mounting portion 11, a hook claw 18 fixedly installed within the mounting portion 11, and an inner contact ring 14, an outer contact ring 13, and an annular shell 16 provided at the bottom of the mounting portion 11. The other end of the hook claw 18 penetrates the bottom of the mounting portion 11 and contacts the inner contact ring 14 and the outer contact ring 13. The inner contact ring 14, the outer contact ring 13, and the annular shell 16 are used to connect the power cord 20, and the connector terminal 21 of the power cord 20 is connected to the power board of the ceiling light.

[0007] In the hook ceiling of this invention, the mounting portion 11 comprises a rectangular room wall 110 having ribs 111 arranged alternately inside. The ribs 111 are provided with mounting grooves 112 for fixing the hook claws 18. The bottom of the mounting portion 11 extends downward, forming an outer convex ring 116, an inner convex ring 117, and a central support column 118 located at the center of the inner convex ring. A first annular mounting area 119a is formed between the outer convex ring 116 and the inner convex ring 117, and a second annular mounting area 119b is formed between the inner convex ring 117 and the central support column 118. The hook claws 18 are fixedly installed in the mounting grooves 112, with their upper end extending upward from the top of the mounting portion 11 to form a hook portion, and their lower end penetrating downward through the bottom of the mounting portion 11. The outer contact ring 13 is installed in the first annular mounting area 119a, and the inner contact ring 14 is installed in the second annular mounting area 119b. The lower end of the hooking claw 18 contacts the inner contact ring 14 and the outer contact ring 13, respectively, to form an electrical path.

[0008] In the hook ceiling of this invention, the hook claw 18 includes a conductive hook 181 such as a copper hook and a contact spring 182. The conductive hook 181 has a suspension arm 1813 whose upper end is bent to form a hook and whose lower end is bent to form a fixing plate 1811. The fixing plate 1811 has a first through hole 1812. The contact spring 182 has a fixing piece 1821 at its upper part that abuts against the fixing plate 1811. The fixing piece 1821 has a second through hole 1822 in its center that corresponds to the first through hole 1812. The fixing piece 1821 extends diagonally downward to form a first elastic arm 1823 and a second elastic arm 1824. The lower end of the second elastic arm 1824 is bent to form a pressure piece 1826, and the center of the pressure piece 1826 is recessed downward to form a pressing portion 1827. The conductive hook 181 and the contact spring 182 are fixedly connected by screws that pass through the first through hole 1812 and the second through hole 1822. The pressing portion 1827 forms conductive contact with the inner contact ring 14 or the outer contact ring 13.

[0009] In the hook ceiling of the present invention, the width of the first elastic arm 1823 is greater than the width of the second elastic arm 1824, and reinforcing ribs 1825 are provided on the outer surfaces of both the first elastic arm 1823 and the second elastic arm 1824.

[0010] In the hook ceiling of this invention, a notch 113 is provided on the side wall of the mounting portion 11, and a release button 12 and a latch 19 are attached thereto. The release button 12 and the latch 19 engage with a wedge-shaped surface, and a return spring is positioned below the latch 19. When the release button 12 is pressed, the wedge-shaped surface pushes the latch 19 laterally, releasing the lock. When the release button is released, the return spring restores the latch to the locked state.

[0011] The annular shell 16 of the hook ceiling of this invention comprises a circular base 160. The edge of the base 160 extends upward to form an outer ring wall 161, the central part of the base 160 extends upward to form an intermediate ring 162, and the central region of the base 160 extends upward to form an inner ring 163. The bottom of the base 160 extends downward to form an outer arc wall 164 and an inner arc wall 165. A first wiring region 16a is formed between the outer arc wall 164 and the inner arc wall 165, and a second wiring region 16b is formed inside the inner arc wall 165. Pins that contact the outer contact ring 13 extend to the first wiring region 16a, and pins that contact the inner contact ring 14 extend to the second wiring region 16b.

[0012] In the hook-type ceiling of this invention, the inside of the intermediate ring 162 is recessed downward to form an annular groove, and a locking hole 166 is provided in the annular groove. The pin that contacts the outer contact ring 13 passes through the locking hole 166 and extends to the first wiring area 16a.

[0013] In the present invention, the hook ceiling fixture has guide walls 167 formed at both ends of the inner curved wall 165 to guide the direction of the power cord 20.

[0014] The hook-type ceiling mount of this invention has cover grooves 115 on both sides of the outer convex ring 116, and lock slots are provided in the cover grooves 115. An insulating top cover 15 made of nylon or the like is fitted into the cover grooves 115 for insulation protection. A hook is provided on the inside of the insulating top cover 15, and when this hook engages with the bayonet (lock slot), the top cover 15 engages with the mounting part 11, and the top cover 15 and the mounting part 11 are connected.

[0015] The hook-type ceiling mount of this invention is provided with fixing lugs 114 at both ends of the mounting portion 11, and these fixing lugs 114 are fixedly connected to the ceiling light via hook-and-loop fasteners.

[0016] Thus, this invention discloses a hook-on ceiling mount that solves the technical problem of low installation efficiency caused by existing hook-on ceiling mounts. This hook-on ceiling mount includes a mounting section in which a hooking claw is fixedly attached. An inner contact ring and an outer contact ring are provided at the bottom of the mounting section. The other end of the hooking claw penetrates the bottom of the mounting section and contacts the inner and outer contact rings. The lower ends of the inner and outer contact rings are used to connect a power cord, and the connector terminals of the power cord are used to connect to the power board of the ceiling light. This solution achieves an electrical connection between the lighting fixture and the mounting base by fixing the hooking claw inside the mounting section and allowing the other end to penetrate the bottom of the mounting section and contact the inner and outer contact rings. This invention simplifies the installation process of lighting fixtures using hook-on connectors, improves production efficiency, and ensures the reliability of the electrical connection.

[0017] The hook-type ceiling mount provided by this invention has the following advantages. This invention provides a hook-type ceiling mount that realizes an electrical connection between a lighting fixture and a mounting base by fixing a hook claw within the mounting part. The other end of the hook claw penetrates the bottom of the mounting part and contacts the inner and outer contact rings. By connecting the power cord using the lower end of the inner and outer contact rings and connecting the connector terminal of the power cord to the power board of the ceiling light, a complete electrical path is formed. This design simplifies the installation process when installing lighting fixtures using hook-type ceiling mounts, avoids the complex electrical connection structure of conventional hook-type ceiling mounts, and improves production efficiency. The structural design of the mounting part allows the hook claw to be stably fixed, ensuring the reliability of the electrical connection. The installation of the inner and outer contact rings separates the wiring between the two poles, effectively preventing the risk of electrical short circuits. The structure in which the hook claw penetrates the bottom of the mounting part and contacts the contact rings eliminates the need for additional connecting parts, reduces the assembly process, and improves assembly efficiency. This integrated electrical connection design not only simplifies the manufacturing process but also improves product reliability. The hook-type ceiling connector enables quick and stable installation and electrical connection of lighting fixtures in practical applications, effectively solving the problem of low assembly efficiency in existing technologies.

Mode for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the scope of the present invention is not limited to the following examples and illustrated examples, and many changes and modifications are possible.

Example

[0021] Referring to FIGS. 1 to 11, the present invention provides a hook seal including a mounting portion 11. A hook claw 18 is fixedly attached inside the mounting portion 11. An inner contact ring 14 and an outer contact ring 13 are provided at the bottom of the mounting portion 11. The other end of the hook claw 18 penetrates the bottom of the mounting portion 11 and abuts against the inner contact ring 14 and the outer contact ring 13. The inner contact ring 14 and the outer contact ring 13 are respectively connected to the power cord 20, and the connector terminals of the power cord 20 are connected to the power supply board of the seal light.

[0022] The hook claw 18 is an integrated component that provides both conductive and mechanical connection functions. Its overall structure must meet the requirements of conductive continuity, mechanical strength, and elastic contact. The hook claw 18 is fixed within the mounting section 11 using fasteners (mounting screws). Its upper end forms a hook for suspending the lighting fixture, and its lower end extends downward, penetrating the bottom of the mounting section 11 to achieve physical contact and electrical connection with the lower contact ring. The conductive path of the hook claw 18 extends along its entire length from the hook end to the contact end. Copper is recommended, but specific materials can be selected based on current capacity and corrosion resistance requirements.

[0023] The inner contact ring 14 and the outer contact ring 13 are concentrically arranged annular conductive components that maintain electrical insulation between them. The outer contact ring 13 is positioned on the outside and the inner contact ring 14 on the inside, forming a bipolar conductive interface. The axial height, radial spacing, and flatness of the two can be adapted and set according to the bottom structure of the mounting portion 11. The lower end of the outer contact ring 13 is provided with a crimp terminal, solder pin, or plug terminal for secure connection to the metal terminal 22b of the power cord 20.

[0024] The other end of the hooking claw 18 penetrates the bottom of the mounting portion 11 and contacts the inner contact ring 14 and the outer contact ring 13. This contact method is either elastic or rigid. The surface of the contact portion may be plated with nickel, silver, or tin to improve conductivity and oxidation resistance. The contact pressure is provided by the structural elasticity of the hooking claw 18 itself, an additional spring, or a pre-compressed spring, ensuring stable contact resistance under conditions such as vibration and thermal expansion and contraction. The inner contact ring 14 and the outer contact ring 13 are connected to wires of different polarities of the power cord 20, respectively. For example, by connecting the outer contact ring 13 to the neutral wire via a metal terminal 22b and the inner contact ring 14 to the live wire via an annular terminal 22a, the hook is attached and the circuit configuration is completed.

[0025] The connector terminal 21 of the power cord 20 is used to connect to the power supply board of the ceiling light. Terminal 21a of the connector terminal 21 is connected to the annular terminal 22a, and terminal 21b is connected to the metal terminal 22b. Methods for connecting the connector terminal 21 to the power supply board of the ceiling light include soldering, IDC crimping (no soldering required), screw terminal connection, or quick connect adapter connection, with a quick connect adapter being preferred. The power supply board can be an LED driver power supply board, a constant current source module, or an intelligent dimming control board, and its input interface corresponds one-to-one with the output terminal of the power cord 20. After exiting the mounting compartment 11, the power cord 20 is routed along the inner wall of the lamp housing and secured using a cable tray, cable tie holes, or cable pass-through holes to prevent loosening due to pulling.

[0026] With the above technical solution, as soon as the ceiling light's suspension operation is complete, the lower end of the hook claw 18 automatically forms stable contact with the inner contact ring 14 and the outer contact ring 13, thus creating a complete path for the current from the hook claw 18, inner contact ring 14, outer contact ring 13, power cord 20, and ceiling light power board. No additional wiring or connection work is required, significantly improving installation efficiency. The separated layout of the inner and outer rings and the physical insulation structure effectively prevent short circuits between the poles. In addition, the through-conductive path and elastic contact design ensure contact reliability and electrical stability during long-term use.

[0027] The mounting portion 11 is integrally injection molded and has a rectangular chamber wall 110 as its main body. On the inside of the chamber wall 110, there are alternately arranged ribs 111, each having a mounting groove 112 for fixing the hook claw 18. The bottom of the mounting portion 11 extends downward and has an outer convex ring 116, an inner convex ring 117, and a central support 118 located in the center of the inner convex ring 117. Between the outer convex ring 116 and the inner convex ring 117, there is a first annular mounting area 119a for mounting the outer contact ring 13. Between the inner convex ring 117 and the central support 118, there is a second annular mounting area 119b for mounting the inner contact ring 14. The side wall of the mounting portion 11 is provided with a notch 113 for mounting and positioning the release button 12. Fixing lugs 114 are provided at both ends of the mounting portion 11, and the mounting portion 11 is fixed to the lamp housing using screws. Cover grooves 115 are provided on both sides of the outer convex ring 116, and inside these grooves are nut positioning holes and bayonet mounts for attaching the nylon top cover 15, thereby providing insulation protection and improving the appearance. Inside the nylon top cover 15 is a hook that engages with the bayonet mount to secure the nylon top cover 15 to the mounting portion 11.

[0028] The ribs 111 are arranged intersectingly along the inside of the chamber wall 110, forming a lattice-like support frame. The cross-sectional shape of the ribs 111 can be rectangular, trapezoidal, or arc-shaped, and their height can be 0.8 to 1.5 times the thickness of the chamber wall 110. This intersecting arrangement evenly distributes stress from the hooks and stress during assembly tightening, improving the bending rigidity and torsional stability of the mounting chamber 11 under long-term suspension loads. The number, spacing, and intersection angle of the ribs 111 can be adjusted according to the molding process requirements and structural strength requirements.

[0029] The outer convex ring 116, the inner convex ring 117, and the central support 118 are all integrally formed from the bottom of the mounting portion 11 and extend downward. They are coaxially arranged, and their axes are perpendicular to the bottom surface of the mounting portion 11. The outer convex ring 116 is an annular projection with an outer diameter slightly smaller than the outer diameter of the bottom surface of the mounting portion 11. The inner convex ring 117 is an annular projection concentrically positioned inside the outer convex ring 116, with an inner diameter larger than the outer diameter of the central support 118. The central support 118 is cylindrical in shape, approximately the same height as or slightly taller than the inner convex ring 117, and serves to provide structural support to the bottom and limit the axial displacement of the inner contact ring 14. The radial dimensional relationships between the outer convex ring 116, the inner convex ring 117, and the central support 118 can be set to match the dimensions of the outer contact ring 13 and the inner contact ring 14.

[0030] This technical solution utilizes the chamber wall 110 and internal ribs (interlace ribs) 111 to employ a high-strength support frame, thereby improving the overall rigidity and deformation resistance of the mounting bin 11 without significantly increasing the volume of the mounting bin 11. The mounting grooves 112 of the ribs 111 ensure accurate axial and circumferential positioning of the hooking claws 18, preventing poor contact due to assembly misalignment. The double-ring mounting area formed by the outer convex ring 116, the inner convex ring 117, and the central support 118 provides independent and stable mounting and positioning of the outer contact ring 13 and the inner contact ring 14, effectively suppressing their displacement and loosening under vibration and thermal expansion and contraction conditions. The central support 118 further enhances the support stability of the bottom structure, preventing collapse of the bottom of the mounting section 11 and ensuring reliable long-term electrical conduction between the hooking claws 18 and the two contact rings.

[0031] Referring to Figures 7 and 8, the hooking claw 18 is formed by screwing together a copper hook 181 and a contact spring 182. The copper hook 181 is made of brass and has a vertical suspension arm 1813. The tip of the suspension arm 1813 is bent at 90° to form a hook 1814, which is quickly attached in conjunction with a suspension groove on the mounting base. The lower part of the suspension arm 1813 is bent at 90° to form a fixing plate 1811, which has a first through hole 1812.

[0032] The contact spring 182 is also made of copper and has a fixing piece 1821 at its top that contacts the fixing plate 1811. A second through hole 1822 corresponding to the first through hole 1812 is formed in the center of the fixing piece 1821. Multiple protrusions are provided around the second through hole 1822 to increase the contact strength with the screw and prevent loosening. The fixing piece 1821 extends diagonally downward to form a first elastic arm 1823 and a second elastic arm 1824. The width of the first elastic arm 1823 is wider than the width of the second elastic arm 1824, and is designed to optimize the transmission path of elastic force. Reinforcing ribs 1825 are provided on the outer surfaces of the first elastic arm 1823 and the second elastic arm 1824 to improve structural strength. The lower end of the second elastic arm 1824 is bent to form a pressure piece 1826. The central part of the pressure piece 1826 is recessed downwards to form a pressing portion 1827, which is used to form surface contact with the inner contact ring 14 or the outer contact ring 13. Two sets of hooking claws 18 are fixed to the mounting groove 112 by screws. The hook 1814 extends upward to the top of the mounting portion 11, and the pressing portion 1827 penetrates downward to the bottom of the mounting portion 11, contacting the inner contact ring 14 and the outer contact ring 13 respectively to form an electrical path.

[0033] The width of the first elastic arm 1823 is wider than the width of the second elastic arm 1824. This means that, at the same cross-sectional position along the extension direction of the elastic arms in the contact spring 182, the dimension perpendicular to the length of the first elastic arm 1823 is larger than the corresponding dimension of the second elastic arm 1824. This difference in width creates an asymmetric stiffness distribution structure, where the first elastic arm 1823 functions as the main load support, responsible for the main bending deformation and torque transmission, while the second elastic arm 1824 functions as a transition, guiding the deformation path and releasing local stresses. The ratio of the widths of the first elastic arm 1823 to the second elastic arm 1824 can be set according to the requirements of the actual contact pressure, rebound stroke, and fatigue life.

[0034] Reinforcement ribs 1825 are provided on the outer surfaces of the first elastic arm 1823 and the second elastic arm 1824, along the longitudinal direction of the elastic arms. The cross-sectional shape of the reinforcement ribs 1825 is rectangular, trapezoidal, or arc-shaped projection, and their height is set according to the bending stiffness requirements. There may be one or more reinforcement ribs 1825. For example, two parallel reinforcement ribs 1825 are provided on the outer surface of the first elastic arm 1823, and one centrally located reinforcement rib 1825 is provided on the outer surface of the second elastic arm 1824. The reinforcement ribs 1825 are integrally molded with the contact spring 182 body by stamping, etching, or injection molding insert molding, and their material matches that of the substrate of the contact spring 182. The arrangement, number, height, and cross-sectional shape of the reinforcement ribs 1825 can be adjusted as appropriate according to the actual needs.

[0035] The outer surfaces of the first elastic arm 1823 and the second elastic arm 1824 refer to the surfaces facing outward from the mounting portion 11 and opposite to the fixing piece 1821. The reinforcing rib 1825 is provided on the surface without changing the assembly gap between the inside of the elastic arm and the adjacent structure, and without affecting the degree of freedom of movement or contact posture of the pressure piece 1826 and the pressing portion 1827.

[0036] This technical solution achieves high bending rigidity due to the wide width of the first elastic arm 1823, which is responsible for the main elastic deformation when the hook 1814 descends under pressure, and suppresses plastic yielding due to overload. The second elastic arm 1824 has excellent flexibility due to its narrow width, enabling controllable bending deformation with a smaller driving force, and ensuring that the pressing portion 1827 smoothly follows the surface of the inner contact ring 14 or the outer contact ring 13. The reinforcing rib 1825 further increases the moment of inertia of the entire elastic arm section, strengthening resistance to torsion and lateral buckling.

[0037] The copper hook 181 is a integrally molded metal part, made of brass, copper, or a copper alloy. It is used to conduct the main circuit current and to provide an external suspension function. The vertical suspension arm 1813 extends longitudinally along the interior of the mounting section 11. Its cross-sectional shape is rectangular, circular, or elliptical, and its size is set according to the actual current-carrying requirements. The hook 1814 is formed by bending the upper part of the suspension arm 1813 horizontally or at an angle, with its opening facing upward. The fixing plate 1811 is formed by bending the lower end of the suspension arm 1813 horizontally or at an angle. It is located inside the bottom of the mounting section 11 and is used to provide an assembly reference surface with the contact spring 182. The first through hole 1812 is a circular through hole located in the central region of the fixing plate 1811, and its diameter is set according to the specifications of the screw used.

[0038] The contact spring 182 is an elastic metal structure for providing continuous and stable contact pressure after assembly. The fixing plate is the upper load-bearing region of the contact spring 182, and its shape conforms to the contour of the fixing plate 1811, and it adheres flat to the surface of the fixing plate 1811. The second through-hole is a circular through-hole located coaxially with the first through-hole 1812, and its diameter is slightly larger than that of the first through-hole 1812, and it houses a screw, enabling press-fitting of the two by tightening. The first elastic arm 1823 and the second elastic arm 1824 form a continuously curved elastic cantilever structure, and their width, thickness, and bending angle are adjusted according to the required elastic force and compression stroke. The pressure piece 1826 is formed by bending the lower end of the second elastic arm, and its plane is perpendicular to the extension direction of the second elastic arm, and it is used to concentrate and transmit the elastic deformation force to the contact region. The pressing portion 1827 is an arc-shaped or spherical recess formed by recessing the central part of the pressure piece 1826 downwards, and its radius of curvature is set according to the surface shape of the contact ring. This recessed structure allows the pressing portion 1827 to make conductive contact with the inner contact ring 14 or the outer contact ring 13.

[0039] The copper hook 181 and contact spring 182 are mechanically fixed and electrically connected by screws passing through the first through hole 1812 and the second through hole 1822. The length of the screws ensures that the fixing piece 1821 is pressed against the surface of the fixing plate 1811 when tightened. The pressing part 1827 also applies a predetermined contact pressure to the contact ring. This connection method avoids non-removable connection processes such as hot working, welding, and riveting, facilitating individual manufacturing, individual inspection, and subsequent replacement and maintenance.

[0040] The pressing portion 1827 forms conductive contact with either the inner contact ring 14 or the outer contact ring 13. After assembling the hook ceiling 10, the lower end of the hook claw 18 passes through the bottom of the mounting portion 11, and the pressing portion 1827 contacts either the upper surface of the inner contact ring 14 or the upper surface of the outer contact ring 13, respectively. The elastic deformation of the contact spring 182 generates vertical pressure, ensuring continuous contact between the pressing portion 1827 and the corresponding contact ring.

[0041] This technical solution enables a modular design and reliable conductive connection of the hook claws 18 in the ceiling hook 10. The copper hook 181 functions as the main load-bearing component, providing high conductivity and structural rigidity. The contact spring 182, an elastic contact component, provides stable, adjustable, and durable contact pressure within a limited space through its multi-stage elastic arm structure and concave design of the pressing section. The two are fastened together with coaxial through-holes and screws, ensuring conductivity of a low-resistance electrical path while also considering adaptability to assembly tolerances and maintainability. As a result, conductive reliability, ease of assembly, and long-term contact stability are significantly improved without changing the overall structure of the ceiling hook 10.

[0042] As shown in Figures 2 and 4, the release button 12 and latch 19 are located in the notch 113 and are engaged by a wedge-shaped inclined surface. A compression spring that provides a reset force is provided at the bottom of the latch 19. When the release button 12 is pressed, the wedge-shaped inclined surface converts the vertical pressing force into a horizontal pressing force, pushing the latch 19 laterally to overcome the spring force and release the lock. When the release button 12 is released, the spring pushes the latch 19 back to its original position, and the wedge-shaped surface engages again, returning it to the locked state. This wedge structure achieves a lever effect, converting a small pressing force into a large locking force, and significantly reducing the operating force.

[0043] The notch 113 is a rectangular or trapezoidal through groove formed in the side wall of the mounting portion 11. Its size and position are determined according to the assembly space requirements of the release button 12 and the latch 19, and correspond to the vertical pressing stroke of the release button 12 and the horizontal sliding stroke of the latch 19. The edge structure of the notch 113 can be customized according to the actual situation. For example, guide chamfers or limiting steps can be provided to guide the release button 12 into place and limit excessive movement.

[0044] The release button 12 is a block-shaped or columnar structure with a wedge-shaped operating surface. Its wedge-shaped surface and the mating surface of the latch 19 are arranged in complementary slanted surfaces. The wedge angle can be set according to the required mechanical gain ratio. The exposed end of the release button 12 is treated with an anti-slip surface or a raised structure to facilitate the application of force by the user.

[0045] The latch 19 is a strip-shaped or L-shaped component that can slide horizontally within the notch 113. The side that engages with the release button 12 is provided with a bevel that conforms to the wedge-shaped surface of the notch 113. The sliding path of the latch 19 is restricted by a guide rail groove or limiting rib provided within the mounting portion 11.

[0046] The return spring is a compression coil spring, with one end in contact with the end of the latch 19 and the other end in contact with a spring seat or baffle pre-installed on the inner wall of the mounting portion 11. The spring force of the return spring is set according to the required locking and holding force of the latch 19.

[0047] This technical solution efficiently converts vertical pressing force into horizontal unlocking drive force using a wedge-shaped surface, reducing the user's operating force. The return spring provides a stable and reliable self-returning function, ensuring that the latch 19 is always in a preloaded locked state and preventing accidental release. The notch 113, release button 12, latch 19, and return spring constitute a compact, integrated linear unlocking mechanism.

[0048] Referring to Figures 9 and 10, the annular shell 16 is integrally injection-molded and comprises a circular base 160. As shown in Figure 9, the edge of the base 160 extends upward to form an outer ring wall 161, the central part of the base 160 extends upward to form an intermediate ring 162, the height of the intermediate ring 162 is lower than the height of the outer ring wall 161, and the central part of the base 160 extends upward to form an inner ring 163. An annular groove is provided on the inside of the intermediate ring 162, and a locking hole 166 for positioning the pin of the outer contact ring 13 is provided in the annular groove. As shown in Figure 10, the bottom of the base 160 extends downward to form an outer arc wall 164 and an inner arc wall 165. A first wiring region 16a is formed between the outer arc wall 164 and the inner arc wall 165, and a second wiring region 16b is formed on the inside of the inner arc wall 165. The pins of the outer contact ring 13 extend through the locking holes 166 to the first wiring area 16a, and the pins of the inner contact ring 14 extend through the inner ring 163 to the second wiring area 16b. Guide walls 167 for guiding the wiring are connected to both ends of the inner arc wall 165, and hollow columns 168 for positioning and fixing the bottom cover 17 are provided on the outer arc wall 164.

[0049] The annular shell 16 is an independently molded insulating structural component, and its material can be customized according to the actual situation, such as flame-retardant polycarbonate, modified polypropylene, or engineering plastic ABS. The circular base 160 is positioned horizontally, and its outer diameter matches the bottom contour of the mounting portion 11, covering the entire exposed area of ​​the bottom of the mounting portion 11. The outer ring wall 161, intermediate ring 162, and inner ring 163 extend vertically upward along the axial direction of the base 160, are arranged concentrically, and their heights decrease in order. The outer ring wall 161 is the tallest and is used to form a restricting fit with the lamp housing or mounting bracket. The intermediate ring 162 supports and positions the outer contact ring 13. The inner ring 163 surrounds and supports the installation area of ​​the inner contact ring 14.

[0050] The outer arc wall 164 and the inner arc wall 165 are both formed by extending downward from the bottom surface of the base 160. Both are arc-shaped side walls, arranged coaxially, and the radius of the outer arc wall 164 is greater than the radius of the inner arc wall 165. The annular gap between the outer arc wall 164 and the inner arc wall 165 constitutes a first wiring area 16a for accommodating pins that contact the outer contact ring 13 and power line branches connected thereto. The central area enclosed by the inner arc wall 165 constitutes a second wiring area 16b for accommodating pins that contact the inner contact ring 14 and corresponding power line branches. The first wiring area 16a and the second wiring area 16b are spatially separated to avoid interference between lines of different potentials and creepage risks.

[0051] The pins of the outer contact ring 13 extend vertically downward from the bottom of the main body, pass through the locking holes 166 in the intermediate ring 162, and enter the first wiring area 16a. The pins of the inner contact ring 14 extend vertically downward from the bottom of the main body and enter the second wiring area 16b through the central opening of the inner ring 163. Each pin either remains naturally suspended within its corresponding wiring area or is constrained by the guide wall 167 to reduce bending stress. The guide wall 167 is connected to both ends of the inner arc wall 165 and has an arc-shaped sheet structure that tapers inward, guiding the power cord 20 along a predetermined path to the ceiling light power board connection end.

[0052] This technical solution realizes an annular shell 16 as an independent protective structure covering the lower surface of the mounting portion 11. The base 160 and the extending ring wall form a sealed wiring cavity with physical isolation. The partition structure formed by the outer arc wall 164 and the inner arc wall 165 allows the pins of the outer contact ring 13 and the inner contact ring 14 to be placed in the uninterconnected first wiring area 16a and second wiring area 16b, respectively, thereby effectively spatially separating high-voltage and low-voltage lines. The guide wall 167, in conjunction with the arc-shaped wall structure, guides and restrains the wiring of the power cord 20, reducing the possibility of damage to the power cord due to bending.

[0053] Guide walls 167 are connected to both ends of the inner curved wall 165 to guide the wiring of the power cord 20. The inner arc wall 165 is an arc-shaped side wall extending downward from the central region of the base 160 of the annular shell 16. Its axial height, radial thickness, and radius of curvature are set according to the actual assembly space and the requirements for compatibility with the outer diameter of the power cable. The guide wall 167 is a strip-shaped or arc-shaped extension structure circumferentially connected to both ends of the inner arc wall 165, restricting and guiding the path of the power cord to the second wiring area 16b. The extension direction of the guide wall 167 coincides with the natural wiring direction of the power cable drawn out from the pin of the inner contact ring 14, allowing the power cable to bend gently along the guide wall surface as it enters the second wiring area 16b, avoiding sharp bends smaller than the minimum allowable bending radius of the power cable. The width, thickness, and cross-sectional shape of the guide wall 167 are not particularly limited. The guide wall 167 can be injection molded integrally with the annular shell 16 or retrofitted using inserts, clips, or ultrasonic welding.

[0054] Figure 11 illustrates how to connect the ends of the power cord 20. The power cord 20 includes two parallel insulated power cords. One of the two power cords extends to the first wiring area 16a of the annular shell 16, and the metal terminal 22b at the end of the power cord is joined to the pin 130 of the outer contact ring 13 using a conductive bonding material 23 (e.g., soldering) (note that in Figure 12, the pin 130 is hidden under the conductive bonding material 23 and is not depicted). The other power cord extends to the second wiring area 16b, and the annular terminal 22a at the end of the power cord is crimped to the pin of the inner contact ring 14. The connector terminals 21 of the two power cords 20 are then connected to the power board of the ceiling light, realizing two-pole independent wiring.

[0055] This technical solution actively restrains the path of the power cable emerging from the inner contact ring 14 pin by providing guide walls 167 at both ends of the inner arc wall 165, preventing irregular bending and interference. The guide walls provide a continuous and smooth guide path, keeping the bending radius of the power cable within the second wiring area 16b above a safety threshold, reducing the risk of dielectric breakdown and conductor breakage. The power cable can be neatly arranged without additional positioning work, improving the overall installation efficiency of the hook ceiling 10.

[0056] The bottom cover 17 is circular and can be injection molded from ABS material. Its edge is provided with a hook that engages with the latch of the cover groove 115, allowing it to be installed without tools. The bottom cover 17 is provided with fixing holes corresponding to the hollow column 168, and when screwed to the annular shell 16, it forms a complete bottom seal structure.

[0057] The operation process of this invention is as follows: During installation, the ceiling light's suspension adapter is pushed up into the suspension groove of the ceiling mounting base. The hook 1814 of the hooking claw 18 engages with the suspension groove, achieving initial positioning. The latch 19 automatically engages with the lock hole of the base due to the action of the spring, completing the mechanical lock. At the same time, the pressing part 1827 makes close contact with the inner contact ring 14 and the outer contact ring 13, forming a stable electrical path. When removing, pressing the release button 12 causes the wedge surface to push the latch 19 laterally, disengaging it from the lock hole and allowing the ceiling light to be removed. Figure 12 shows a cross-sectional view of a ceiling hook.

[0058] The ceiling hook provided by this invention has the following advantages. This invention provides a ceiling hook with a hooking claw fixed to the mounting part. The other end of the hooking claw penetrates the bottom of the mounting part and contacts the inner and outer contact rings, thereby realizing an electrical connection between the lighting fixture and the mounting base. A complete electrical path is formed by connecting the power cord using the lower ends of the inner and outer contact rings and connecting the other end of the power cord to the power board of the lighting fixture. This design simplifies the installation process when installing lighting fixtures using a ceiling hook, avoids the complex electrical connection structure of conventional ceiling hooks, and improves production efficiency. The structural design of the mounting part allows for stable fixing of the hooking claw, ensuring the reliability of the electrical connection. The arrangement of the inner and outer contact rings allows for the separation of wiring between the two poles, effectively preventing the risk of short circuits. The structure in which the hooking claw penetrates the bottom of the mounting part and contacts the contact rings eliminates the need for additional connecting parts, reduces the assembly process, and improves assembly efficiency. This integrated electrical connection design not only simplifies the manufacturing process but also improves product reliability. The hook-type ceiling connector enables quick and stable installation and electrical connection of lighting fixtures in practical applications, effectively solving the problem of low assembly efficiency in existing technologies.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be within the scope of protection of the present invention.
